(1)Pursuant to Rule 416(a) of the Securities Act of 1933, as amended ('Securities Act'), there are also being registered an indeterminable number of additional securities as may be issued to prevent dilution resulting from stock splits, stock dividends or similar transactions.

(2)New Nextdoor Class A common stock issuable upon the conversion of New Nextdoor Class B common stock, including upon exercise or settlement of New Nextdoor stock options and restricted stock units ('RSUs').

(3)Pursuant to Rule 457(i) promulgated under the Securities Act, no separate registration fee is required.

In addition, in connection with the closing of KVSB's initial public offering, KVSB entered into a forward purchase agreement pursuant to which the Sponsor (and its transfers and assigns, if any), agreed to purchase, upon the closing of KVSB's initial business combination if necessary to meet the Minimum Cash Condition, an aggregate of up to 1,000,000 shares of New Nextdoor Class A common stock for an aggregate purchase price of $10,000,000, or $10.00 per share, of New Nextdoor Class A common stock.

Pursuant to KVSB's current certificate of incorporation, its public stockholders may demand that KVSB redeem their shares of KVSB Class A common stock for cash if the Business Combination is consummated. Public stockholders will be entitled to receive cash for their shares of KVSB Class A common stock without voting and, if they do vote, irrespective of whether they vote for or against the BCA Proposal. If the Business Combination is not completed, these shares of KVSB Class A common stock will not be redeemed. If a public stockholder properly demands redemption, KVSB will redeem each share of KVSB Class A common stock for a pro rata portion of the trust account holding the proceeds from KVSB's initial public offering, calculated as of two business days prior to the Closing.

Thank you for your participation. We look forward to your continued support.

By Order of the Board of Directors

These risks and uncertainties include, but are not limited to, those factors described under the heading 'Risk Factors' beginning on page 34 of this proxy statement/prospectus. Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. KVSB and Nextdoor undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws.

Before any KVSB stockholder grants its proxy or instructs how its vote should be cast or votes on the proposals to be put to the special meeting, such stockholder should be aware that the occurrence of the events described in the 'Risk Factors' section and elsewhere in this proxy statement/prospectus may adversely affect us.

Q: What proposals are stockholders of KVSB being asked to vote upon?

A: At the special meeting, KVSB is asking holders of KVSB common stock to consider and vote upon:

a.a proposal to approve and adopt the Merger Agreement (the 'BCA Proposal');

b.a proposal to approve, assuming the BCA Proposal is approved and adopted, the Proposed Charter, which will amend and restate the Existing Charter, and which Proposed Charter will be in effect when duly filed with the Secretary of State of the State of Delaware in connection with the Closing (the 'Charter Proposal');

c.several proposals to approve, on a non-binding advisory basis, the following material differences between the Proposed Charter and the Current Charter, which are being presented in accordance with the requirements of the SEC as seven separate sub-proposals (the 'Advisory Charter Amendment Proposals'):

i.Advisory Charter Amendment Proposal A - To change KVSB's name to 'Nextdoor Holdings, Inc.';

ii.Advisory Charter Amendment Proposal B - To increase the number of authorized shares of New Nextdoor Class A common stock, New Nextdoor Class B common stock and 'blank check' preferred stock and to eliminate the authorized shares of KVSB Class K common stock;

iii.Advisory Charter Amendment Proposal C - To provide that holders of New Nextdoor Class A common stock will be entitled to one vote per share of New Nextdoor

Class A common stock and holders of New Nextdoor Class B common stock will be entitled to ten votes per share of New Nextdoor Class B common stock;

iv.Advisory Charter Amendment Proposal D - To require that stockholders only act at annual and special meeting of the corporation and not by written consent;

v.Advisory Charter Amendment Proposal E - To eliminate the current limitations in place on the corporate opportunity doctrine;

vi.Advisory Charter Amendment Proposal F - To establish the required vote thresholds for approving amendments to the Proposed Charter as follows: (i) at least two-thirds of the voting power of all of the then outstanding shares of capital stock will be required to amend certain provisions of the Proposed Charter, including provisions relating to the classified board, the size of the New Nextdoor board of directors, removal of directors, special meetings, actions by written consent and designation of our preferred stock, provided that if two-thirds of the New Nextdoor board of directors has approved such amendment only the affirmative vote of a majority of the voting power of all of the then outstanding shares of capital stock shall be required to amend the Proposed Charter, (ii) at least two-thirds of the voting power of the New Nextdoor Class B common stock will be required to amend certain provisions relating to the New Nextdoor Class B common stock and take certain other actions that impact the New Nextdoor Class B common stock, and (iii) the affirmative vote of holders of at least 75% of the voting power of each of our Class A common stock and Class B common stock, voting separately by class, will be required to amend certain provisions of the Proposed Charter relating to the terms of the New Nextdoor Class A common stock or New Nextdoor Class B common stock; and

vii.Advisory Charter Amendment Proposal G - To approve all other changes including eliminating certain provisions related to special purpose acquisition corporations that will no longer be relevant following the Closing.

d.a proposal to approve, for purposes of complying with the applicable provisions of Nasdaq Listing Rule 5635, the issuance of New Nextdoor common stock to (a) the PIPE Investors, including the Sponsor Related PIPE Investor and the Nextdoor PIPE Investors, pursuant to the PIPE Investment, (b) the New Nextdoor stockholders pursuant to the Merger Agreement and (c) the Sponsor (or its assigns) pursuant to the Forward Purchase Agreement (the 'Stock Issuance Proposal');

e.a proposal to approve the New Nextdoor Equity Incentive Plan, a copy of which is attached to this proxy statement/prospectus as Annex H (the 'Equity Incentive Plan Proposal');

f.a proposal to approve the New Nextdoor Employee Stock Purchase Plan, a copy of which is attached to this proxy statement/prospectus as Annex I (the 'ESPP Proposal'); and

g.a proposal to approve the adjournment of the special meeting to a later date or dates, if necessary, to permit further solicitation and vote of proxies in the event that there are insufficient votes for the approval of one or more proposals at the special meeting (the 'Adjournment Proposal').

If KVSB's stockholders do not approve each of the Condition Precedent Proposals, then unless certain conditions in the Merger Agreement are waived by the applicable parties to the Merger Agreement, the Merger Agreement could terminate and the Business Combination may not be consummated. See the sections entitled 'BCA Proposal,' 'Charter Proposal,' 'Stock Issuance Proposal,' 'Equity Incentive Plan Proposal,' 'ESPP Proposal' and 'Adjournment Proposal.'

KVSB will hold the special meeting to consider and vote upon these proposals. This proxy statement/prospectus contains important information about the Business Combination and the other matters to be acted upon at the special meeting. Stockholders of KVSB should read it carefully.

After careful consideration, the KVSB Board has determined that the BCA Proposal, each of the Charter Proposal, the Advisory Charter Amendment Proposals, the Stock Issuance Proposal, the Equity Incentive Plan

xii

Proposal, the ESPP Proposal and the Adjournment Proposal, if necessary, are in the best interests of KVSB and its stockholders, and unanimously recommends that you vote or give instruction to vote 'FOR' each of those proposals, if presented to the special meeting.

The existence of financial and personal interests of one or more of KVSB's directors may result in a conflict of interest on the part of such director(s) between what he, she or they may believe is in the best interests of KVSB and its stockholders and what he, she or they may believe is best for himself, herself or themselves in determining to recommend that stockholders vote for the proposals. In addition, KVSB's officers have interests in the Business Combination that may conflict with your interests as a stockholder. See the section entitled 'BCA Proposal - Interests of KVSB's Directors and Executive Officers in the Business Combination' for a further discussion of these considerations.

Q: Are the proposals conditioned on one another?

A: Yes. The Business Combination is conditioned on the approval of each of the Condition Precedent Proposals at the special meeting. Each of the Condition Precedent Proposals is cross-conditioned on the approval of each other. The Advisory Charter Amendment Proposals and the Adjournment Proposal are each not conditioned upon the approval of any other proposal.

Q: Why is KVSB proposing the Business Combination?

A: KVSB was organized to effect a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination, with one or more businesses or entities.

Based on its due diligence investigations of Nextdoor and the industry in which they operate, including the financial and other information provided by Nextdoor in the course of KVSB's due diligence investigations, the KVSB board of directors (the 'KVSB Board') believes that the Business Combination with Nextdoor is in the best interests of KVSB and its stockholders and presents an opportunity to increase stockholder value. However, there is no assurance of this. See the section entitled 'BCA Proposal - The KVSB Board's Reasons for the Business Combination' for additional information.

Although the KVSB Board believes that the Business Combination with Nextdoor presents a unique business combination opportunity and is in the best interests of KVSB and its stockholders, the KVSB Board did consider the following potentially material negative factors in arriving at that conclusion:

a.Execution risks associated with Nextdoor's business. For an additional description of these risks, see the section entitled 'Risk Factors.'

b.Liquidation of KVSB.The risks and costs to KVSB if the Business Combination is not completed, including the risk of diverting management focus and resources from other businesses combination opportunities, which could result in KVSB being unable to effect a business combination within the timeframe provided for under its Existing Charter and forcing KVSB to liquidate.

c.Exclusivity.The fact that the Merger Agreement includes an exclusivity provision that prohibits KVSB from soliciting other business combination proposals and restricts KVSB's ability to consider other potential business combinations so long as the Merger Agreement is in effect.

d.Stockholder vote.The risk that KVSB's stockholders may fail to provide the respective votes necessary to effect the Business Combination.

e.Redemption risk. The risk that the current public stockholders of KVSB would redeem their public shares for cash in connection with consummation of the Business Combination, thereby reducing the amount of cash available to Nextdoor following the consummation of the Business Combination and potentially allowing Nextdoor to terminate the Business Combination.

f.Post-business combination corporate governance. The KVSB Board considered the corporate governance provisions of the Merger Agreement and the proposed material provisions of the Proposed Governing Documents

xiii

and the effect of those provisions on the governance of Nextdoor. See the sections entitled 'BCA Proposal - The Merger Agreement' and 'Management of Nextdoor Following the Business Combination' for detailed discussions of the terms and conditions of these documents.

g.Limitations of review. The KVSB Board considered that it was not obtaining a third-party valuation or fairness opinion from any independent investment banking or accounting firm. In addition, KVSB's management and outside counsel reviewed only certain materials in connection with their due diligence review of Nextdoor. Accordingly, the KVSB Board considered that KVSB may not have properly valued Nextdoor.

h.Closing conditions.The fact that completion of the Business Combination is conditioned on the satisfaction of certain closing conditions that are not within KVSB's control.

i.KVSB stockholders holding a minority position in Nextdoor. The fact that KVSB's stockholders will hold a minority position in the post-combination company (approximately 9.7% assuming that no shares of KVSB Class A common stock are elected to be redeemed by KVSB stockholders), which may reduce the influence that KVSB's current stockholders have on the management of Nextdoor.

j.No survival of remedies for breach of representations, warranties or covenants of Nextdoor.That the terms of the Merger Agreement provide that KVSB will not have any surviving remedies against Nextdoor after the Closing to recover for losses as a result of any inaccuracies or breaches of Nextdoor's representations, warranties or covenants set forth in the Merger Agreement.

k.Litigation.The possibility of litigation challenging the Business Combination or that an adverse judgment granting injunctive relief could indefinitely delay or otherwise permanently prohibit consummation of the Business Combination.

l.Fees and expenses.The fees and expenses associated with completing the Business Combination.

m.Other risks.Various other risks associated with the Business Combination, the business of KVSB and the business of Nextdoor described under the section entitled 'Risk Factors.'

These factors are discussed in greater detail in the sections entitled 'BCA Proposal - The KVSB Board's Reasons for the Business Combination' and 'Risk Factors - Risks Related to Nextdoor's Business and Industry.'

Q: What will Nextdoor Stockholders receive in return for KVSB's acquisition of all of the issued and outstanding equity interests of Nextdoor?

A: At the effective time of the Merger, among other things, Nextdoor's equityholders (assuming the vesting and exercise on a net basis as of the Closing of all Nextdoor options that will be assumed or substituted in the Business Combination) will receive an aggregate of 350.0 million shares of New Nextdoor Class B common stock. For further details, see the sections entitled 'BCA Proposal - The Merger Agreement - Consideration to Nextdoor Stockholders in the Merger' and 'Equity Incentive Plan Proposal.'

Q: What is the value of the consideration to be received in the Merger?

A: The exact value of the consideration to be received by holders of equity interests of Nextdoor at the Closing will depend on the price of shares of common stock of KVSB as of such time and the aggregate fully diluted number of shares of Nextdoor common stock as of such time, and will not be known with certainty until the Closing.

For informational purposes only, assuming (i) a purchase price of $10.00 per share, (ii) the aggregate fully diluted number of shares of Nextdoor common stock as of Closing of 112,724,907 (and a resulting Exchange Ratio of approximately 3.1049) and (iii) a market price of KVSB Class A common stock of $ per share (based on

xiv

the closing price of KVSB Class A common stock on Nasdaq on ,2021), if the Closing had occurred on , 2021, then, each share of the fully diluted Nextdoor common stockwould have been canceled and converted into the right to receive shares of New Nextdoor Class B common stock with an aggregate market value (based on the market price of KVSB Class A common stock as of such date) of $ .

We have provided the above calculations for informational purposes only based on the assumptions set forth above. The actual Exchange Ratio will be determined at the Closing pursuant to the formula and terms set forth in the Merger Agreement. The aggregate number of fully diluted shares of Nextdoor common stock as of Closing, and the market price of public shares assumed for purposes of the foregoing illustration are each subject to change, and the actual values for such inputs at the time of the Closing could result in the actual Exchange Ratio and the value of the consideration to be received by holders of equity interests in Nextdoor being more or less than the amounts reflected above. We urge you to obtain current market quotations for public shares.

The 41,634,412 shares of New Nextdoor Class A common stock collectively held by KVSB's public stockholders, if unrestricted and freely tradable, would have had an aggregate market value of approximately $ million based upon the closing price of $ per share on Nasdaq on , 2021, the most recent practicable date prior to the date of this proxy statement/prospectus. Based on the above assumed prices, the aggregate value KVSB public stockholders will receive with the Business Combination and related transactions is approximately $ million. The 10,232,269 shares of New Nextdoor Class B common stock into which the founder shares held by the Sponsor will convert and be exchanged in connection with the Merger, if unrestricted, fully vested and freely tradable, would have had an aggregate market value of approximately $ million based upon the closing price of $ per share on Nasdaq on , 2021, the most recent practicable date prior to the date of this proxy statement/prospectus. The 176,334 shares of New Nextdoor Class B common stock into which the 120,000 shares of KVSB Class B common stock held by KVSB's independent directors will automatically convert and be exchanged in connection with the Merger, if unrestricted and freely tradable, would have had an aggregate market value of approximately $ million based upon the closing price of $ per share on Nasdaq on , 2021, the most recent practicable date prior to the date of this proxy statement/prospectus. The 1,132,688 shares of New Nextdoor Class B common stock that will be issued to Sponsor in exchange for the 1,132,688 private placement shares held by the Sponsor, if unrestricted and freely tradable, would have had an aggregate market value of approximately $ million based upon the closing price of $ per share on the Nasdaq on , 2021, the most recent practicable date prior to the date of this proxy statement/prospectus. The Sponsor Related PIPE Investors have subscribed for $7.5 million of the PIPE Investment, for which they will receive 750,000 shares of New Nextdoor Class A common stock, which, if unrestricted and freely tradable, would have had an aggregate market value of approximately $ million based upon the closing price of $ per share on Nasdaq on , 2021, the most recent practicable date prior to the date of this proxy statement/prospectus. Based on the current price, the aggregate value Sponsor and related parties will receive with the Business Combination and related transactions is approximately $ , all of which will be subject to a lock-up.

Q: What equity stake will current KVSB stockholders and Nextdoor Stockholders hold in New Nextdoor immediately after the consummation of the Business Combination?

A: As of the date of this proxy statement/prospectus, KVSB had 52,767,100 shares of KVSB common stock issued and outstanding, which includes the 10,000,000 founder shares held by the Sponsor and the independent directors (without giving effect to the conversion and exchange of the founder shares into New Nextdoor Class B common stock in connection with the closing of the Business Combination), the 1,132,688 private placement shares held by the Sponsor and the 41,634,412 public shares.

Investors are expected to own approximately 7.1% of the outstanding New Nextdoor common stock (and 0.8% of the voting power of the New Nextdoor common stock). These percentages assume (i) that no public stockholders exercise their redemption rights in connection with the Business Combination, (ii) the exclusion of (a) an estimated 62,168,894 shares of New Nextdoor Class B common stock reserved for potential future issuance upon the exercise of New Nextdoor Options and settlement of New Nextdoor RSUs or New Nextdoor Restricted Stock Awards (or 47,698,062 shares of New Nextdoor Class B common stock assuming that all Nextdoor Awards are net settled at a deemed value of $10.00 per share and a weighted-average exercise price for the New Nextdoor Options of $2.35 per share after giving effect to the Exchange Ratio) and (b) an estimated 180,503 shares of New Nextdoor Class B common stock related to certain entitlements to receive Nextdoor common stock pursuant to the terms of the Pixel Labs Merger Agreement, which were canceled and converted into the right to receive New Nextdoor Class B common stock equal to the Exchange Ratio multiplied by the number of Nextdoor common stock held by such holder immediately prior to the Effective Time, (iii) the inclusion of New Nextdoor Class B common stock issued as the Aggregate Merger Consideration pursuant to the Merger Agreement, which in the aggregate equals 302,532,879 shares of New Nextdoor Class B common stock, (iv) New Nextdoor issues 27,000,000 shares of New Nextdoor Class A common stock to the PIPE Investors pursuant to the PIPE Investment, (v) New Nextdoor issues zero shares of New Nextdoor common stock to Sponsor (together with any permitted transferees under the Forward Purchase Agreement) pursuant to the Forward Purchase Agreement, (vi) the conversion and exchange of all outstanding KVSB Class B common stock shares into an aggregate of 7,347,249 shares of New Nextdoor Class B common stock, (vii) the conversion of all outstanding private placement shares purchased by the Sponsor simultaneously with the consummation of the initial public offering of KVSB into an aggregate of 1,132,688 shares of New Nextdoor Class B common stock and (viii) the conversion of all outstanding KVSB Class K common stock shares into an aggregate of 3,061,354 shares of New Nextdoor Class B common stock. If the actual facts are different from these assumptions, the percentage ownership retained by the Company's existing stockholders in the combined company will be different.

The following table illustrates varying ownership levels in New Nextdoor immediately following the consummation of the Business Combination based on the assumptions above:


Share Ownership in New Nextdoor
Pro Forma Combined (Assuming No Redemptions)	Pro Forma Combined (Assuming Maximum Redemptions)(5)
Class A	Class B(2)	Class A	Class B(2)
Number of Shares	Number of Shares	% Ownership	% Voting	Number of Shares	Number of Shares	% Ownership	% Voting
Nextdoor stockholders(1)	-	302,532,879	79.0	%	94.3	%	-	302,532,879	84.3	%	95.0	%

(5)Assumes maximum redemptions of 24,932,638 public shares of KVSB's Class A common stock in connection with the Transactions at an assumed redemption price of approximately $10.00 per share based on funds held in the trust account as of June 30, 2021 and still satisfy the Minimum Cash Condition required to consummate the Transactions of at least $400.0 million after giving effect to the proceeds from the PIPE Investment, the payment of the estimated transaction costs, and the proceeds from the Sponsor Forward Purchase Agreement.

(6)Excludes the PIPE Investment made by the Sponsor Related PIPE Investors and includes shares held by members of the board of directors of KVSB.

For further details, see 'BCA Proposal - The Merger Agreement - Consideration to Nextdoor Stockholders in the Merger.'

Q: What is the maximum number of shares that may be redeemed in order for KVSB to satisfy the Minimum Cash Condition?

A: Assuming aggregate transaction expenses of $47.0 million and that the PIPE Investment is completed and the full amount of the Forward Purchase Agreement is funded to KVSB, the maximum number of shares that may be redeemed in order for KVSB to satisfy the Minimum Cash Condition is 24,932,638.

Q: How has the announcement of the Business Combination affected the trading price of the public shares?

A: On July 2, 2021, the trading date before the public announcement of the Business Combination, KVSB's public shares closed at $9.91. On , 2021, the most recent practicable date prior to the date of this proxy statement/prospectus, KVSB's public shares closed at $ .

Q: Will the Company obtain new financing in connection with the Business Combination?

A: Yes. The PIPE Investors have agreed to purchase in the aggregate 27.0 million shares of New Nextdoor common stock, for approximately $270.0 million of gross proceeds, in the PIPE Investment, a portion of which is expected to be funded by the Sponsor Related PIPE Investor and Nextdoor PIPE Investors. The PIPE Investment is contingent upon, among other things, the closing of the Business Combination. See the sections entitled 'BCA Proposal - Related Agreements - Subscription Agreements' and '- Forward Purchase Agreement.'

Q: Do I have redemption rights?

A: If you are a holder of public shares, you have the right to request that we redeem all or a portion of your public shares for cash provided that you follow the procedures and deadlines described elsewhere in this proxy statement/prospectus. Public stockholders may elect to redeem all or a portion of the public shares held by them regardless of if or how they vote in respect of the BCA Proposal. If you wish to exercise your redemption rights, please see the answer to the next question: 'How do I exercise my redemption rights?'

Notwithstanding the foregoing, a public stockholder, together with any affiliate of such public stockholder or any other person with whom such public stockholder is acting in concert or as a 'group' (as defined in Section 13(d)(3) of the Exchange Act), will be restricted from redeeming its public shares with respect to more than an aggregate of 15% of the public shares. Accordingly, if a public stockholder, alone or acting in concert or as a group, seeks to redeem more than 15% of the public shares, then any such shares in excess of that 15% limit would not be redeemed for cash.

The Sponsor and KVSB's independent directors have agreed to waive their redemption rights with respect to all of the founder shares in connection with the consummation of the Business Combination. The founder shares will be excluded from the pro rata calculation used to determine the per-share redemption price.

Q: How do I exercise my redemption rights?

A: If you are a public stockholder and wish to exercise your right to redeem the public shares, you must:

a.hold public shares;

xvii

b.submit a written request to Continental Stock Transfer & Trust Company, KVSB's transfer agent, that New Nextdoor redeem all or a portion of your public shares for cash; and

c.deliver your public shares to Continental Stock Transfer & Trust Company, KVSB's transfer agent, physically or electronically through The Depository Trust Company ('DTC').

Holders must complete the procedures for electing to redeem their public shares in the manner described above prior to 5:00 p.m., Eastern Time, on , 2021 (two business days before the special meeting) in order for their shares to be redeemed.

The address of Continental Stock Transfer & Trust Company, KVSB's transfer agent, is listed under the question 'Who can help answer my questions?' below.

Public stockholders will be entitled to request that their public shares be redeemed for a pro rata portion of the amount then on deposit in the trust account calculated as of two business days prior to the consummation of the Business Combination including interest earned on the funds held in the trust account and not previously released to us (net of taxes payable). For illustrative purposes, as of , 2021, this would have amounted to approximately $ per issued and outstanding public share. However, the proceeds deposited in the trust account could become subject to the claims of KVSB's creditors, if any, which could have priority over the claims of the public stockholders, regardless of whether such public stockholder votes or, if they do vote, irrespective of if they vote for or against the BCA Proposal. Therefore, the per share distribution from the trust account in such a situation may be less than originally expected due to such claims. Whether you vote, and if you do vote irrespective of how you vote, on any proposal, including the BCA Proposal, will have no impact on the amount you will receive upon exercise of your redemption rights. It is expected that the funds to be distributed to public stockholders electing to redeem their public shares will be distributed promptly after the consummation of the Business Combination.

Any request for redemption, once made by a holder of public shares, may be withdrawn at any time until the deadline for exercising redemption requests and thereafter, with KVSB's consent, until the time the vote is taken with respect to the BCA Proposal at the special meeting. If you deliver your shares for redemption to , KVSB's transfer agent, and later decide prior to the special meeting not to elect redemption, you may request that KVSB's transfer agent return the shares (physically or electronically) to you. You may make such request by contacting Continental Stock Transfer & Trust Company, KVSB's transfer agent, at the phone number or address listed at the end of this section.

Any corrected or changed written exercise of redemption rights must be received by Continental Stock Transfer & Trust Company, KVSB's transfer agent, prior to the vote taken on the BCA Proposal at the special meeting. No request for redemption will be honored unless the holder's public shares have been delivered (either physically or electronically) to Continental Stock Transfer & Trust Company, KVSB's transfer agent, at least two business days prior to the vote at the special meeting.

If a demand to exercise redemption rights is properly made as described above, then, if the business combination is consummated, KVSB will redeem these shares for a pro rata portion of funds deposited in the trust account. If you exercise your redemption rights, then you will be exchanging your public shares for cash.

Q: What are the U.S. federal income tax consequences of exercising my redemption rights?

A: The U.S. federal income tax consequences of exercising redemption rights that may be relevant to holders of shares of KVSB Class A common stock are discussed in more detail in the section entitled 'U.S. Federal Income Tax Considerations - Material U.S. Federal Income Tax Consequences of the Redemption of KVSB Public Stockholders.' The discussion of the U.S. federal income tax consequences contained in this proxy statement/prospectus is intended to provide only a general discussion and is not a complete analysis or description of all of the U.S. federal income tax considerations that are applicable to holders of shares of KVSB Class A common stock in respect of the exercise of their redemption rights, nor does it address any tax considerations arising under U.S. state or local or non-U.S. tax laws.

xviii

TAX MATTERS ARE COMPLICATED, AND THE TAX CONSEQUENCES TO HOLDERS OF SHARES OF KVSB CLASS A COMMON STOCK OF EXERCISING THEIR REDEMPTION RIGHTS WILL DEPEND ON THE FACTS OF THEIR OWN SITUATION. EACH HOLDER OF SHARES OF KVSB CLASS A COMMON STOCK SHOULD CONSULT THEIR OWN TAX ADVISOR AS TO THE SPECIFIC TAX CONSEQUENCES OF THE EXERCISE OF REDEMPTION RIGHTS TO SUCH HOLDER IN THEIR PARTICULAR CIRCUMSTANCES.

Q: What happens to the funds deposited in the trust account after consummation of the Business Combination?

A: Following the closing of KVSB's initial public offering, a total of approximately $416.3 million, comprised of proceeds from KVSB's initial public offering and certain proceeds from the sale of the private placement shares, was placed in the trust account. As of June 30, 2021, funds in the trust account totaled $416.4 million and were invested in U.S. government treasury bills with a maturity of 185 days or less or in money market funds investing solely in U.S. Treasuries and meeting certain conditions under Rule 2a-7 under the Investment Company Act of 1940, as amended. These funds will remain in the trust account, except for the withdrawal of interest to fund KVSB's working capital requirements, subject to an annual limit of $500,000, and/or to pay taxes, if any, until the earliest of (1) the completion of a business combination (including the closing of the Business Combination), (2) the redemption of any public shares properly tendered in connection with a stockholder vote to amend the Existing Organizational Documents to modify the substance or timing of KVSB's obligation to redeem 100% of the public shares if it does not complete a business combination within 24 months from the closing of the initial public offering or (ii) with respect to any other provisions relating to stockholders' rights or pre-initial business combination activity, and (c) the redemption of all of the Company's public shares if it is unable to complete its business combination within 24 months from the closing of the initial public offering, subject to applicable law.

Upon consummation of the Business Combination, the funds deposited in the trust account will be released to pay holders of public shares who properly exercise their redemption rights; to pay transaction fees and expenses associated with the Business Combination; and for working capital and general corporate purposes of New Nextdoor following the Business Combination. See 'Summary of the Proxy Statement/Prospectus - Sources and Uses of Funds for the Business Combination.'

Q: What happens if a substantial number of the public stockholders vote in favor of the BCA Proposal and exercise their redemption rights?

A: Our public stockholders are not required to vote in respect of the Business Combination in order to exercise their redemption rights. Accordingly, the Business Combination may be consummated even though the funds available from the trust account and the number of public stockholders are reduced as a result of redemptions by public stockholders.

The Merger Agreement provides that the obligations of Nextdoor to consummate the Merger are conditioned on, among other things, the satisfaction of the Minimum Cash Condition. If such condition is not met, and such condition is not waived under the terms of the Merger Agreement, then the Merger Agreement could terminate and the proposed Business Combination may not be consummated. There can be no assurance that Nextdoor would waive the Minimum Cash Condition. In addition, pursuant to the Existing Organizational Documents, in no event will we redeem public shares in an amount that would cause New Nextdoor's net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) of the Exchange Act) to be less than $5,000,001.

Q: What conditions must be satisfied to complete the Business Combination?

A: The Merger Agreement is subject to the satisfaction or waiver of certain customary closing conditions, including, among others, (i) approval of the Transactions and related matters by KVSB's stockholders and equity holders of the Nextdoor Parties, (ii) the effectiveness of the Registration Statement of which this proxy statement/prospectus forms a part, (iii) the receipt of certain regulatory approvals (including, but not limited to, approval for listing on Nasdaq of the shares of New Nextdoor Class A common stock issuable upon the conversion of New Nextdoor Class B common stock to be issued in connection with the Merger and related transactions and the

xix

expiration or early termination of the waiting period or periods under the HSR Act), (iv) that KVSB has at least $5,000,001 of net tangible assets upon Closing and (v) the absence of any injunctions.

Nextdoor's obligation to consummate the Merger is also conditioned on the requirement that as of the Closing, the Available Cash (the sum of the Trust Amount, the PIPE Investment Amount and the Forward Purchase Amount (if any), after payment of transaction expenses) is equal to or greater than $400 million.

For more information about conditions to the consummation of the Business Combination, see the section entitled 'BCA Proposal - The Merger Agreement.'

Q: What are the material U.S. federal income tax consequences of the Merger to holders of Nextdoor common stock?

A: Certain material U.S. federal income tax considerations that may be relevant to holders of Nextdoor common stock in respect of the Business Combination are discussed in more detail in the section entitled 'U.S. Federal Income Tax Considerations - Material U.S. Federal Income Tax Consequences of the Merger.' The discussion of the U.S. federal income tax consequences contained in this proxy statement/prospectus is intended to provide only a general discussion and is not a complete analysis or description of all of the U.S. federal income tax considerations that are applicable to holders of Nextdoor common stock in respect of the Merger, nor does it address any tax considerations arising under U.S. state or local or non-U.S. tax laws.

TAX MATTERS ARE COMPLICATED, AND THE TAX CONSEQUENCES OF THE BUSINESS COMBINATION WILL DEPEND ON THE FACTS APPLICABLE TO EACH HOLDER OF NEXTDOOR COMMON STOCK. EACH HOLDER OF NEXTDOOR COMMON STOCK SHOULD CONSULT THEIR OWN TAX ADVISOR AS TO THE SPECIFIC TAX CONSEQUENCES OF THE BUSINESS COMBINATION TO SUCH HOLDER BASED ON SUCH HOLDER'S PARTICULAR CIRCUMSTANCES.

Q: When do you expect the Business Combination to be completed?

A: It is currently expected that the Business Combination will be consummated in the fourth quarter of 2021. This date depends, among other things, on the approval of the proposals to be put to KVSB stockholders at the special meeting. However, such meetings could be adjourned if the Adjournment Proposal is adopted at the special meeting, and KVSB elects to adjourn the special meeting to a later date or dates, if necessary, to permit further solicitation and vote of proxies in the event that there are insufficient votes for the approval of one or more proposals at the special meeting. For a description of the conditions for the completion of the Business Combination, see 'BCA Proposal - The Merger Agreement.'

Q: What happens if the Business Combination is not consummated?

A: If KVSB is not able to complete the Business Combination with Nextdoor by the Liquidation Date and is not able to complete another business combination by such date, in each case, as such date may be extended pursuant to the Existing Organizational Documents, KVSB will: (1) cease all operations except for the purpose of winding up; (2) as promptly as reasonably possible, but not more than 10 business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest (less up to $100,000 of interest to pay dissolution expenses and which interest shall be net of taxes payable), divided by the number of then issued and outstanding public shares, which redemption will completely extinguish public stockholders' rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law; and (3) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our board, dissolve and liquidate, subject in each case to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

Q: Do I have appraisal rights in connection with the proposed Business Combination?

A: KVSB's stockholders do not have appraisal rights in connection with the Business Combination under the DGCL.

Q: What do I need to do now?

A: KVSB urges you to read this proxy statement/prospectus, including the Annexes and the documents referred to herein, carefully and in their entirety and to consider how the Business Combination will affect you as a stockholder. KVSB's stockholders should then vote as soon as possible in accordance with the instructions provided in this proxy statement/prospectus and on the enclosed proxy cards, as applicable.

Q: How do I vote?

A: If you are a holder of record of KVSB Class A common stock and KVSB Class B common stock on the record date for the special meeting, you may vote in person virtually at the special meeting or by submitting a proxy for the special meeting. You may submit your proxy by completing, signing, dating and returning the enclosed proxy cards, as applicable, in the accompanying pre-addressed postage-paid envelope. If you hold your shares in 'street name,' which means your shares are held of record by a broker, bank or nominee, you should contact your broker, bank or nominee to ensure that votes related to the shares you beneficially own are properly counted. In this regard, you must provide the broker, bank or nominee with instructions on how to vote your shares or, if you wish to virtually attend the special meeting and vote in person, obtain a valid proxy from your broker, bank or nominee.

Q: If my shares are held in 'street name,' will my broker, bank or nominee automatically vote my shares for me?

A: No. If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the 'beneficial holder' of the shares held for you in what is known as 'street name.' If this is the case, this proxy statement/prospectus may have been forwarded to you by your brokerage firm, bank or other nominee, or its agent, and you may need to obtain a proxy form from the institution that holds your shares and follow the instructions included on that form regarding how to instruct your broker, bank or nominee as to how to vote your shares. Under the rules of various national and regional securities exchanges, your broker, bank, or nominee cannot vote your shares with respect to non-discretionary matters unless you provide instructions on how to vote in accordance with the information and procedures provided to you by your broker, bank, or nominee. We believe all the proposals presented to the stockholders will be considered non-discretionary and therefore your broker, bank, or nominee cannot vote your shares without your instruction. Your bank, broker, or other nominee can vote your shares only if you provide instructions on how to vote. As the beneficial holder, you have the right to direct your broker, bank or other nominee as to how to vote your shares and you should instruct your broker to vote your shares in accordance with directions you provide. If you do not provide voting instructions to your broker on a particular proposal on which your broker does not have discretionary authority to vote, your shares, as applicable, will not be voted on that proposal. This is called a 'broker non-vote.' A broker non-vote will not be counted towards the quorum requirement, as we believe all proposals presented to the stockholders will be considered non-discretionary, or count as a vote cast at the special meeting.

Q: When and where will the special meeting be held?

A: The special meeting will be held will be held virtually via live webcast at at , Eastern Time, on , 2021, or such other date, time and place to which such meeting may be adjourned or postponed, to consider and vote upon the proposals.

Q: How do I attend a virtual meeting?

A: As a registered stockholder, you will receive the applicable proxy card(s) from .

Q: Who is entitled to vote at the special meeting?

A: KVSB has fixed , 2021 as the record date for the special meeting. If you were a stockholder of KVSB at the close of business on the record date, you are entitled to vote on matters that come before the special meeting. However, a stockholder may only vote his or her shares if he or she is present in person virtually or is represented by proxy at the special meeting.

Q: How many votes do I have?

A: KVSB stockholders are entitled to:

(i)one vote at the special meeting for each share of KVSB Class A common stock held of record as of the record date; and

(ii)1.4694498 votes at the special meeting for each share of KVSB Class B common stock held of record as of the record date, except for purposes of the BCA Proposal KVSB stockholders will be entitled to only one vote at the special meeting for each share of KVSB Class B common stock held of record as of the record date.

The holders of outstanding shares of KVSB Class K common stock are not entitled to vote except as provided by law or our certificate of incorporation.

As of the close of business on the record date for the special meeting, there were shares of KVSB Class A common stock issued and outstanding (of which were issued and outstanding public shares), shares of KVSB Class B common stock issued and outstanding and shares of KVSB Class K common stock issued and outstanding.

Q: What constitutes a quorum?

A: A quorum of KVSB stockholders is necessary to hold a valid meeting. A quorum will be present at the special meeting if the holders of outstanding KVSB common stock representing a majority of the voting power of all outstanding shares entitled to vote at the special meeting are represented in person or by proxy at the special meeting. As of the record date for the special meeting, an aggregate of shares of KVSB Class A common stock and KVSB Class B common stock (on an as-converted basis) would be required to achieve a quorum.

Q: What vote is required to approve each proposal at the special meeting?

A: The following votes are required for each proposal at the special meeting:

a.BCA Proposal: The approval of the BCA Proposal requires the affirmative vote of holders of a majority of the shares of KVSB Class A common stock and KVSB Class B common stock that are voted at the special meeting.

xxii

Assuming the minimum number of shares of KVSB Class A common stock and KVSB Class B common stock representing a quorum are present and voted, and assuming that all shares of KVSB Class B common stock and all private placement shares are present and voted in favor of the BCA Proposal, a total of 5,809,088 public shares would need to be voted in favor of the BCA Proposal.

b.Charter Proposal: The approval of the Charter Proposal requires (1) the affirmative vote of holders of a majority of the voting power of the outstanding shares of KVSB Class A common stock and KVSB Class B common stock, voting together as a single class, (2) the affirmative vote or written consent of the holders of a majority of the voting power of the outstanding shares of KVSB Class K common stock, voting separately as a series (which consent has already been obtained prior to the special meeting) and (3) the affirmative vote or written consent of the holders of a majority of the voting power of the outstanding shares of KVSB Class B common stock, voting separately as a series.

c.Advisory Charter Amendment Proposals: The approval of the Advisory Charter Amendment Proposals require the affirmative vote of holders of a majority of the votes cast by holders of shares of KVSB Class A common stock and KVSB Class B common stock represented in person or by proxy and entitled to vote thereon, voting together as a single class.

d.Stock Issuance Proposal: The approval of the Stock Issuance Proposal requires the affirmative vote of the holders of a majority of the votes cast by holders of shares of KVSB Class A common stock and KVSB Class B common stock represented in person or by proxy and entitled to vote thereon, voting together as a single class.

e.Equity Incentive Plan Proposal: The approval of the Equity Incentive Plan Proposal requires the affirmative vote of a majority of the votes cast by holders of shares of KVSB Class A common stock and KVSB Class B common stock represented in person or by proxy and entitled to vote thereon, voting together as a single class.

f.ESPP Proposal: The approval of the ESPP Proposal requires the affirmative vote of a majority of the votes cast by holders of shares of KVSB Class A common stock and KVSB Class B common stock represented in person or by proxy and entitled to vote thereon, voting together as a single class.

g.Adjournment Proposal: The approval of the Adjournment Proposal requires the affirmative vote of a majority of the votes cast by holders of shares of KVSB Class A common stock and KVSB Class B common stock represented in person or by proxy and entitled to vote thereon, voting together as a single class.

Q: What are the recommendations of KVSB's board of directors?

A: The KVSB Board believes that the BCA Proposal and the other proposals to be presented at the special meeting are in the best interest of KVSB's stockholders, and unanimously recommends that you vote or give instruction to vote 'FOR' the BCA Proposal, 'FOR' the Charter Proposal, 'FOR' each of the separate Advisory Charter Amendment Proposals, 'FOR' the Stock Issuance Proposal, 'FOR' the Equity Incentive Plan Proposal, 'FOR' the ESPP Proposal, and 'FOR' the Adjournment Proposal, in each case, if presented to the special meeting.

Q: How does the Sponsor intend to vote its shares?

A: Unlike some other blank check companies in which the initial stockholders agree to vote their shares in accordance with the majority of the votes cast by the public stockholders in connection with an initial business combination, the Sponsor and all of its directors and officers have agreed to vote all of the shares of KVSB common

xxiii

stock they may hold in favor of all the proposals being presented at the special meeting. As of the date of this proxy statement/prospectus, the Sponsor and KVSB's independent directors collectively own issued and outstanding shares of KVSB common stock representing 16.9% of the outstanding voting power on an as-converted basis, and 12.8% of the outstanding voting power on a per actual share basis.

At any time at or prior to the Business Combination, subject to applicable securities laws (including with respect to material nonpublic information), the Sponsor, the existing stockholders of Nextdoor or our or their respective directors, officers, advisors or respective affiliates may (i) purchase public shares from institutional and other investors who vote, or indicate an intention to vote, against any of the Condition Precedent Proposals, or elect to redeem, or indicate an intention to redeem, public shares, (ii) execute agreements to purchase such shares from such investors in the future or (iii) enter into transactions with such investors and others to provide them with incentives to acquire public shares, vote their public shares in favor of the Condition Precedent Proposals or not redeem their public shares. Such a purchase may include a contractual acknowledgement that such stockholder, although still the record holder of KVSB's shares, is no longer the beneficial owner thereof and therefore agrees not to exercise its redemption rights. In the event that the Sponsor, the existing stockholders of Nextdoor or our or their respective directors, officers, advisors, or respective affiliates purchase shares in privately negotiated transactions from public stockholders who have already elected to exercise their redemption rights, such selling stockholders would be required to revoke their prior elections to redeem their shares. The purpose of such stock purchases and other transactions would be to (x) increase the likelihood of approving the Condition Precedent Proposals and (y) limit the number of public shares electing to redeem, including to satisfy any redemption threshold.

Entering into any such arrangements may have a depressive effect on KVSB common stock (e.g., by giving an investor or holder the ability to effectively purchase shares at a price lower than market, such investor or holder may therefore become more likely to sell the shares he or she owns, either at or prior to the Business Combination). If such transactions are effected, the consequence could be to cause the Business Combination to be consummated in circumstances where such consummation could not otherwise occur. Purchases of shares by the persons described above would allow them to exert more influence over the approval of the proposals to be presented at the special meeting and would likely increase the chances that such proposals would be approved. KVSB will file or submit a Current Report on Form 8-K to disclose any material arrangements entered into or significant purchases made by any of the aforementioned persons that would affect the vote on the proposals to be put to the special meeting or the redemption threshold. Any such report will include descriptions of any arrangements entered into or significant purchases by any of the aforementioned persons.

The existence of financial and personal interests of one or more of KVSB's directors may result in a conflict of interest on the part of such director(s) between what he, she or they may believe is in the best interests of KVSB and its stockholders and what he, she or they may believe is best for himself or themselves in determining to recommend that stockholders vote for the proposals. In addition, KVSB's officers have interests in the Business Combination that may conflict with your interests as a stockholder. See the section entitled 'BCA Proposal - Interests of KVSB's Directors and Executive Officers in the Business Combination' for a further discussion of these considerations.

Q: What happens if I sell my KVSB common stock before the special meeting?

A: The record date for the special meeting is earlier than the date of the special meeting and earlier than the date that the Business Combination is expected to be completed. If you transfer your public shares after the applicable record date, but before the special meeting, unless you grant a proxy to the transferee, you will retain your right to vote at such special meeting, as applicable, but the transferee, and not you, will have the ability to redeem such shares (if time permits).

Q: May I change my vote after I have mailed my signed proxy card(s)?

A: Yes. Stockholders may send later-dated, signed proxy card(s) to KVSB's Secretary at KVSB's address set forth below so that such proxy card(s) received by KVSB's Secretary prior to the vote at the special meeting, as applicable (which is scheduled to take place on , 2021) or virtually attend the special meeting, as applicable, in person and vote. Stockholders also may revoke their proxy by sending a notice of revocation to KVSB's Secretary, which must be received by KVSB's Secretary prior to the vote at the special meeting, as

xxiv

applicable. However, if your shares are held in 'street name' by your broker, bank or another nominee, you must contact your broker, bank or other nominee to change your vote.

Q: What happens if I fail to take any action with respect to the special meeting?

A: If you fail to take any action with respect to the special meeting and the Business Combination is approved by stockholders and the Business Combination is consummated, you will become a stockholder of New Nextdoor. If you fail to take any action with respect to the special meeting and the Business Combination is not approved, you will remain a stockholder of KVSB. However, if you fail to vote with respect to the special meeting, you will nonetheless be able to elect to redeem your public shares in connection with the Business Combination (if time permits).

Q: What should I do with my share certificates?

A: Our stockholders who exercise their redemption rights must deliver (either physically or electronically) their share certificates to , KVSB's transfer agent, prior to the special meeting.

Public stockholders who do not elect to have their public shares redeemed for the pro rata share of the trust account should not submit the certificates relating to their public shares.

Upon the completion of the Merger, holders of KVSB Class A common stock, KVSB Class B common stock and KVSB Class K common stock will hold shares of New Nextdoor Class A common stock without needing to take any action and, accordingly, such holders should not submit any certificates relating to their KVSB Class A common stock (unless such holder elects to redeem the public shares in accordance with the procedures set forth above), KVSB Class B common stock or KVSB Class K common stock.

Q: What should I do if I receive more than one set of voting materials?

A: Stockholders may receive more than one set of voting materials, including multiple copies of this proxy statement/prospectus and multiple proxy cards or voting instruction cards. For example, if you hold your shares in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold shares. If you are a holder of record and your shares are registered in more than one name, you will receive more than one proxy card for each applicable meeting. Please complete, sign, date and return each proxy card and voting instruction card that you receive in order to cast a vote with respect to all of your KVSB common stock.

Q: Who will solicit and pay the cost of soliciting proxies for the special meeting?

A: KVSB will pay the cost of soliciting proxies for the special meeting. KVSB has engaged (' ') to assist in the solicitation of proxies for the special meeting. KVSB has agreed to pay a fee of $ , plus disbursements (to be paid with non-trust account funds). KVSB will also reimburse banks, brokers and other custodians, nominees and fiduciaries representing beneficial owners of KVSB Class A common stock for their expenses in forwarding soliciting materials to beneficial owners of KVSB Class A common stock and in obtaining voting instructions from those owners. KVSB's directors and officers may also solicit proxies by telephone, by facsimile, by mail, on the Internet or in person. They will not be paid any additional amounts for soliciting proxies.

Q: Where can I find the voting results of the special meeting?

A: The preliminary voting results will be expected to be announced at the special meeting, as applicable. KVSB will publish final voting results of the special meeting in a Current Report on Form 8-K within four business days after the special meeting.

Business Summary

Nextdoor is the neighborhood network

At Nextdoor, our purpose is to cultivate a kinder world where everyone has a neighborhood they can rely on. Every day we come to work to leverage technology to connect millions of neighbors online and in real life to build stronger, more vibrant, and resilient neighborhoods.

The simple human truth is that we are all social creatures. We crave connection to the people and places around us. Countless studies show that well-being is higher among people who have regular contact with their neighbors. According to a Nextdoor global loneliness study, knowing as few as six neighbors reduces the likelihood of feeling lonely and is linked to lower depression, social anxiety, and financial concerns.

It has been inspiring to see kindness thriving in neighborhoods around the globe, and we are confident that using technology to enable real-world connections is possible and makes a difference.

Global flywheel of growth

Today, Nextdoor is in more than 280,000 neighborhoods around the world. In the United States, nearly 1 in 3 households turn to Nextdoor to access trusted information, give and get help, and build real-world connections with people and organizations nearby - including neighbors, small and mid-sized businesses, large brands, public agencies, and nonprofits. Nextdoor is the neighborhood network that brings all of these stakeholders together to get things done locally and build thriving communities.

Our business strengthens as we scale, benefiting from strong network effects. Our sole focus on neighborhoods has allowed us to optimize our product and strategy to drive neighbor growth and engagement on our platform. As neighborhood adoption of Nextdoor increases, activity among neighbors also increases, adding more relevant local content. This prompts more engagement from other neighbors, leading to further growth through word of mouth and an enhanced overall experience that strengthens neighbor retention. As of June 30, 2021, our three month neighbor retention was 76%, our six month neighbor retention was 67%, our one year neighbor retention was 59%, and our two year neighbor retention was 57%. Our retention rate only includes neighbors who were active in the last 30 days of the period for which our retention rate is calculated. Once a neighbor joins and experiences the value of Nextdoor, they are very likely to stay and continue to engage on our platform.

In addition, other major stakeholders in the neighborhood such as businesses and public agencies, also contribute to this flywheel of growth. We see businesses asking neighbors to join and recommend their business. We see public agencies actively recruiting neighbors so that they can be assured that urgent alerts and other messages are getting widespread distribution. These viral growth loops will continue to drive growth and engagement on Nextdoor.

Our need to be connected to neighbors was amplified during the pandemic - and that need is real and lasting. For the three months ended June 30, 2021, neighbors who engaged with Nextdoor daily posted 2.1 times more often than in the same prior year period. As the world reopens, consumer behavior is changed for good, with an increased focus on local.

Neighborhoods matter more than ever

Everyone around the world is a neighbor whether they reside in a city, suburb, small town, or a rural area - we are all part of a neighborhood. We all want to feel connected and to belong. According to a recent study from Open Mind Strategy, 73% of U.S. adults say neighbors are one of the most important communities in their lives.

We also know local consumption has taken on greater importance. Consumer behavior has structurally changed post pandemic, with an increasing interest and involvement in day-to-day local activities. According to Brightpearl, 75% of neighbors plan to shop more locally and according to Owl Labs, 80% expect to work from home at least three times per week.

Furthermore, once neighbors are on our platform, they stay and use it frequently due to the utility that it affords them. Weekly active users engage with Nextdoor nearly four times a week in 2020, making Nextdoor one of the most frequently used consumer products, according to data from App Annie.

Just as people turn to digital networks to enhance their work (e.g., LinkedIn) and play (e.g., Instagram and TikTok), they are looking for a way to do the same in their neighborhood. As the neighborhood network, Nextdoor is an authentic, purpose driven brand that connects neighbors online and offline.

Strong competitive moat with viral growth loops built in

Nextdoor offers neighbors around the world the unique ability to connect to their neighborhood, feel welcome, and belong. We leverage technology to enable online and real-world connections between neighbors, businesses, and public agencies - all of which are a valuable part of the neighborhood ecosystem.

Our mission is to be the neighborhood hub for trusted connections and the exchange of helpful information, goods, and services. To that end, we have built Nextdoor one neighbor, one street, one neighborhood at a time, based on our powerful points of difference.

Our strengths helped us create a new category and give us a competitive advantage:

•Real people: We ensure neighbors are connected to real people by requiring everyone to sign up with their real names and addresses.

•Hyperlocal proximity: We connect people to their neighborhood ecosystem based on physical proximity. We also connect them to the broader set of neighborhoods that matter to them, such as where they work, where their parents or children live, where they own a business, and where they might be interested in moving.

•Trusted information: From day one, Nextdoor has been built on trusted information. This includes connecting neighbors to credible hyperlocal information from relevant authorities. Government entities and organizations - from Mayor Khan in London to the Ministry of Health in France or the Red Cross in Houston - use Nextdoor to be the go-to source for sharing real time information with the neighborhood.

•Local perspective: Whether a neighbor wants to give or get help, they can get a truly insider perspective from their neighbors on Nextdoor. Want to find out who to use for a babysitter, how to get involved in the community clean up, or if the bakery still has fresh donuts? Neighbors are a first hand source for highly relevant hyperlocal information and recommendations.

during a hurricane or wildfire. We also instantly connect businesses to customers nearby. Given that most commerce is local, providing hyperlocal reach at scale without needing to build followership is a key differentiator for Nextdoor.

These strengths lead to viral growth loops in the product across our three distinct audiences - neighbors, businesses, and public agencies. For example, neighbors often flag to local businesses that other neighbors are looking for their services. Businesses often invite neighbors to Nextdoor in order to leave a recommendation. And public agencies often actively recruit neighbors to Nextdoor as we become their de facto communication platform.

Three distinct audiences

Connecting neighbors to the neighborhood

Neighbors come to Nextdoor to connect to the neighborhoods that matter to them. They turn to Nextdoor daily to access trusted information, give and get help, and build real-world connections with neighbors, businesses, and public agencies.

How neighbors discover what's happening nearby

•Newsfeed. The Newsfeed is where neighbors find constantly updated posts, discussions, photos, and links.

•Notifications. In-app Notifications inform neighbors about news, items, and activities they are interested in.

•Search. Search gives neighbors the ability to find specific content and businesses related to their neighborhood.

How neighbors find local resources

•Businesses. Neighbors visit the Businesses section to discover spots most loved by locals, find exclusive deals and promotions, and interact with business owners' updates.

•Finds. Finds is our truly local marketplace where neighbors buy, sell, or give away items, and even offer services such as babysitting and dog walking.

•Recommendations. Neighbors can reach out to those who know best for recommendations nearby.

How neighbors connect with other neighbors

•Posts, Comments and Reactions. Posts, Comments and Reactions enable neighbors to express themselves through a variety of content types and reach out to the neighborhood to get and give information that is locally relevant, trusted, and in real time.

•Groups. Neighbors create Groups to connect with those nearby with a common interest.

•Messaging. Neighbors can contact other neighbors and organizations through direct messaging.

Connecting businesses to their customers

How large brands reach their customers

•Sponsored Post in Newsfeed. Large brands use Sponsored Posts in the Newsfeed to build awareness. Ads are featured prominently where neighbors first look for what is happening on Nextdoor.

•Sponsored Post Email and In-App Digest. Large brands can also use Sponsored Posts in the Email and In-App Digests to create awareness among neighbors who turn to their summary of top posts.

•Sponsored Post in Finds. Large brands can leverage Sponsored Posts in Finds to drive action such as shop now. Our local marketplace is where neighbors with high intent to buy will go.

How small businesses reach their customers

•Neighborhood Sponsorships. Small businesses leverage Neighborhood Sponsorships to drive awareness, build a positive reputation, and keep their business top of mind.

•Local Deals. Small businesses and neighbors offering services use Local Deals to target specific neighborhoods and drive sales.

Connecting public agencies to their constituents

How public agencies keep constituents informed

•Emergency alerts. Public agencies use our platform to post real-time, geo-targeted alerts to inform neighbors in need.

•Respond to questions. Agency employees are able to manage content and respond to questions from the neighbors in their area.

•Education. Agencies can keep the neighbors in the areas they serve, up to date on information and education relevant to them.

Strong business model with a unique selling proposition

Our solutions set help businesses reach their goals, from awareness to action:

•Access to untapped audiences. According to Comscore data from March 2021, 63% of the users who visit Nextdoor at least once a month did not visit Twitter, 52% did not visit Pinterest, and 27% did not visit Facebook and Facebook Messenger.

•High relevance. Neighbor content is highly relevant to the locality in which it is placed and provides a unique environment for our customers to place their message - with the ability to reach across varying demographics and geographies.

•Neighborhood level data provides actionable insights. We have a unique ability to track consumer behavior and trends from a national to a neighborhood level. In March 2020, we launched our proprietary Nextdoor Insights Series, showcasing U.S. neighborhood trends. Our trove of data can provide valuable insights to our customers to help them better serve their customers.

•Hyperlocal targeting and customization. Businesses can reach neighbors near them at scale with personalized messaging.

•Timely reach with high intent audiences. Neighbors often come to Nextdoor looking for a real-time solution nearby. This creates an attractive environment for our customers.

Large and growing total addressable market

On Nextdoor, large brands, small and mid-sized businesses, and public agencies benefit from our hyperlocal targeting to provide relevant information to people in their neighborhoods. Our customers enjoy instant access to our large base of engaged neighbors that can be harder to find on other platforms. Many of our neighbors come to Nextdoor to access local information and get things done in their neighborhoods, and brands on Nextdoor are able to provide applicable information at the time that they are ready to act.

The total global digital advertising market for consumers was estimated at $355 billion in 2020, growing by 71% to $607 billion in 2024.This estimate is based on data from eMarketer and excludes 6% of digital advertising spend which is, by our estimation, business-to-business spend and which Nextdoor does not address.

Over time, we believe we can also build new revenue streams in addition to advertising.

Growth strategies with powerful network effects

We are focused on the following growth strategies:

•Increase neighbors on our network. As of June 30, 2021, we had nearly 47 million claimed households (defined as a household with at least one Verified Neighbor) worldwide. Reaching total penetration in-line with our top quartile U.S. neighborhoods would increase our reach to over 200 million households. To date, we have primarily grown organically, with neighbors inviting other neighbors to connect through word of mouth, email invitations, and mailed invites. To continue our momentum and expand our network, we are focused on product-driven growth and global growth.

Our product-driven growth centers around enabling an active valued community, making it easy to discover our platform, invite others to join Nextdoor, and share content. We believe that allowing neighbors to access and discover neighborhood content through online search will drive fast understanding and adoption of our platform. Our global growth builds on the successes we have seen in markets outside of the United States.

We will continue to invest in making it easier to engage, share interests, and create meaningful connections.

•Increase monetization on our platform. We are still in the early stages of monetization on our platform and believe there are many vectors for sustained revenue growth.

Scaling our advertising business involves further improving advertising products and tools, organizing and growing our salesforce, and investing in media agency relationships. We are continuing to invest in our self-serve advertising platform which will improve ad relevance and decisioning.

For additional information, see 'Adjournment Proposal.'

KVSB's Board of Directors' Reasons for the Business Combination

KVSB was organized for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses.

In evaluating the Business Combination, the KVSB Board consulted with KVSB's management and considered a number of factors. In particular, the KVSB Board considered, among other things, the following factors, although not weighted or in any order of significance:

has allowed it to optimize its product and strategy to drive neighbor growth and engagement on its platform. Historically, as neighborhood adoption increased, activity among neighbors also increased, adding more relevant local content. This has prompted more engagement from other neighbors, leading to further growth through word of mouth and an enhanced overall experience that strengthens neighbor retention. Other major stakeholders in the neighborhood, such as businesses and public agencies also contribute to this flywheel of growth. Further, the KVSB Board believes that the Nextdoor platform is unique in its ability to enable online and real-world connections between neighbors, businesses, and public agencies which are a valuable part of the neighborhood ecosystem.

•Each social link is highly valuable because most commerce is local.The KVSB Board considered the fact that each social link on Nextdoor is highly valuable because most commerce is local. Nextdoor neighbors tend to be in an advertiser-friendly demographic: as of December 2020, 61% were women, 93% were over 25 years old, 79% were homeowners, and they had a median annual income of $90,000. Consumer behavior has changed during the pandemic, with an increasing interest and involvement in day-to-day local activities.

•Robust current digital advertising market and future potential revenue models.The KVSB Board considered the fact that the total global digital advertising market for consumers is large and expanding and that Nextdoor has developed a suite of highly engaging digital ad formats such as video and maps, self-serve advertising capabilities, measurement tools, and a vertically-focused sales force to capture a greater share of digital advertising spend. In addition the KVSB Board considered the fact that Nextdoor has the potential to build new revenue streams over time, including potential monetization opportunities from Nextdoor's Finds marketplace, the facilitation of local commerce, home services, real estate, and local events.

•Many growth vectors for revenue.The KVSB Board considered the fact that Nextdoor is in the early stages of monetizing its platform. However, the KVSB Board also considered the fact that Nextdoor seems well positioned to scale its advertising business and to develop new revenue streams, and that there is potential for international expansion both in terms of users and monetization of international users.

•Competitive position is strong: hard and slow early network to build.The KVSB Board considered the fact that Nextdoor competes in almost every aspect of its business with companies that provide a variety of internet products, services, content, and online advertising, including Facebook, Google, Pinterest, Snap, and Twitter. However, the KVSB Board also considered the fact that unlike these competitors, Nextdoor has been singularly focused, over an extended period of time, on creating and strengthening its neighborhood networks (which contain both physical and digital aspects).

•Team well positioned for acceleration and execution.The KVSB Board considered the fact that Nextdoor after the business combination will be led by the senior management team of Nextdoor. The KVSB Board also believes that the willingness of Nextdoor's management team to roll over their equity stake and subject their equity stakes to prohibitions on the transfer of their Nextdoor equity for a period of time following the consummation of the Business Combination reflected management's belief in and commitment to Nextdoor's continued growth following the consummation of the Business Combination.

•Backed by strong investor syndicate.Nextdoor's existing investors include Benchmark Capital, Shasta Ventures, Greylock Partners, and Tiger Global. The KVSB Board believes these investors provide additional validation to Nextdoor's business strategies, innovation and high-growth potential.

•Financial analysis conducted by KVSB.The financial analysis conducted by KVSB's management team and reviewed by the KVSB Board supported the equity valuation of Nextdoor. See the section entitled '- Projected Financial Information.'

business plan based upon the process used to evaluate and assess other potential acquisition targets, and the KVSB Board's belief that such process has not presented a better alternative.

•Negotiated transaction.The financial and other terms of the Merger Agreement and the fact that such terms and conditions are reasonable and were the product of arm's length negotiations between KVSB and Nextdoor.

For a more complete description of the KVSB board of directors' reasons for approving the Business Combination, including other factors and risks considered by the KVSB board of directors, see the section entitled 'BCA Proposal - KVSB's Board of Directors' Reasons for the Business Combination.'

Forward Purchase Agreement

In connection with the closing of KVSB's initial public offering, the Sponsor entered into the Forward Purchase Agreement pursuant to which the Sponsor (together with any permitted transferees under the Forward Purchase Agreement) agreed to purchase, upon the closing of KVSB's initial business combination, an aggregate of up to 1,000,000 shares of KVSB Class A common stock, for an aggregate purchase price of up to $10,000,000, or $10.00 per share, of KVSB Class A common stock. The proceeds from the sale of these forward-purchase shares, together with the amounts available to KVSB from the trust account (after giving effect to any redemptions of public shares) and any other equity or debt financing obtained by it in connection with the Business Combination, will be used to satisfy the cash requirements of the Business Combination, including funding the purchase price and paying expenses and retaining specified amounts to be used by the post-Business Combination company for working capital or other purposes. To the extent that the amounts available from the trust account and other financing are sufficient for such cash requirements, the Sponsor may purchase less than 1,000,000 forward-purchase shares.

Ownership of New Nextdoor following Business Combination

As of the date of this proxy statement/prospectus, KVSB had 52,767,100 shares of KVSB common stock issued and outstanding, which includes the 10,000,000 founder shares held by the Sponsor (including KVSB's independent directors), 1,132,688 private placement shares and 41,634,412 public shares.

It is anticipated that, following the Business Combination, (1) KVSB's public stockholders are expected to own approximately 10.9% of the outstanding New Nextdoor common stock (and 1.3% of the voting power of the New Nextdoor common stock), (2) Nextdoor Stockholders (without taking into account any public shares held by Nextdoor Stockholders prior to the consummation of the Business Combination) are expected to own approximately 79.0% of the outstanding New Nextdoor common stock (and 94.3% of the voting power of the New Nextdoor common stock), (3) the Sponsor and related parties are expected to own approximately 3.0% of the outstanding New Nextdoor common stock (and 3.6% of the voting power of the New Nextdoor common stock) and (4) the PIPE Investors are expected to own approximately 7.1% of the outstanding New Nextdoor common stock (and 0.8% of the voting power of the New Nextdoor common stock). These percentages assume (i) that no public stockholders exercise their redemption rights in connection with the Business Combination, (ii) the exclusion of (a) an estimated 62,168,894 shares of New Nextdoor Class B common stock reserved for potential future issuance upon the exercise of New Nextdoor Options and settlement of New Nextdoor RSUs or New Nextdoor Restricted Stock Awards and (b) an estimated 180,503 shares of New Nextdoor Class B common stock related to certain entitlements to receive Nextdoor common stock pursuant to the terms of the Pixel Labs Merger Agreement, which were canceled and converted into the right to receive New Nextdoor Class B common stock equal to the Exchange Ratio multiplied by the number of Nextdoor common stock held by such holder immediately prior to the Effective Time, (iii) the inclusion of New Nextdoor Class B common stock issued as the Aggregate Merger Consideration pursuant to the Merger Agreement, which in the aggregate equals 302,532,879 shares of New Nextdoor Class B common stock, (iv) New Nextdoor issues 27,000,000 shares of New Nextdoor Class A common stock to the PIPE Investors pursuant to the PIPE Investment, (v) New Nextdoor issues zero shares of New Nextdoor common stock to Sponsor (together with any permitted transferees under the Forward Purchase Agreement) pursuant to the Forward Purchase Agreement, (vi) the conversion and exchange of all outstanding KVSB Class B common stock shares into an aggregate of 7,347,249 shares of New Nextdoor Class B common stock, (vii) the conversion of all outstanding private placement shares purchased by the Sponsor simultaneously with the consummation of the initial public offering of KVSB into an aggregate of 1,132,688 shares of New Nextdoor Class B common stock and (viii) the conversion of all outstanding KVSB Class K common stock shares into an aggregate of 3,061,354 shares of New Nextdoor Class B common stock. If the actual facts are different from these assumptions, the percentage ownership retained by the Company's existing stockholders in the combined company will be different.

The following table illustrates varying ownership levels in New Nextdoor immediately following the consummation of the Business Combination based on the assumptions above.

For illustrative purposes, as of , 2021, this would have amounted to approximately $10.00 per issued and outstanding public share. If a public stockholder exercises its redemption rights in full, then it will be electing to exchange its public shares for cash and will no longer own public shares. The redemption takes place following the Business Combination and, accordingly, it is shares of New Nextdoor common stock that will be redeemed immediately after consummation of the Business Combination. See the section entitled 'Special Meeting of KVSB - Redemption Rights' in this proxy statement/prospectus for a detailed description of the procedures to be followed if you wish to redeem your public shares for cash.

The Sponsor has agreed to vote in favor of the Business Combination, regardless of how our public stockholders vote. Unlike some other blank check companies in which the initial stockholders agree to vote their shares in accordance with the majority of the votes cast by the public stockholders in connection with an initial business combination, the Sponsor and each director of KVSB have agreed to, among other things, vote in favor of the Merger Agreement and the transactions contemplated thereby, in each case, subject to the terms and conditions contemplated by the Sponsor Support Agreement. As of the date of this proxy statement/prospectus, the Sponsor (including KVSB's independent directors) owns issued and outstanding KVSB common stock representing 16.9% of the outstanding voting power on an as-converted basis, and 12.8% of the outstanding voting power on a per actual share basis.

Appraisal Rights

KVSB stockholders do not have appraisal rights in connection with the Business Combination under the DGCL.

Proxy Solicitation

Proxies may be solicited by mail, telephone or in person. KVSB has engaged to assist in the solicitation of proxies.

If a stockholder grants a proxy, it may still vote its shares in person if it revokes its proxy before the special meeting. A stockholder also may change its vote by submitting a later-dated proxy as described in the section entitled 'Special Meeting of KVSB - Revoking Your Proxy.'

Interests of KVSB's Directors and Executive Officers in the Business Combination

When you consider the recommendation of the KVSB Board in favor of approval of the BCA Proposal, you should keep in mind that the Sponsor and KVSB's directors and executive officers have interests in such proposal that are different from, or in addition to, those of KVSB stockholders generally. These interests include, among other things, the interests listed below:

•Prior to KVSB's initial public offering, the Sponsor purchased 10,000,000 founder shares, for $0.0025 per share. Subsequent to the share capitalization, the Sponsor transferred 40,000 founder shares to each of Enrico Gaglioti, Anita Sands and Dmitri Schlosser, KVSB's independent directors. If KVSB does not consummate a business combination by the Liquidation Date, it would cease all operations except for the purpose of winding up, redeeming all of the outstanding public shares for cash and, subject to the approval of its remaining stockholders and its board of directors, dissolving and liquidating, subject in each case to its obligations under the DGCL to provide for claims of creditors and the requirements of other applicable law. In such event, the 10,000,000 founder shares owned by the Sponsor and KVSB's independent directors would be worthless because following the redemption of the public shares, KVSB would likely have few, if any, net assets and because the Sponsor and KVSB's directors and officers have agreed to waive their respective rights to liquidating distributions from the trust account in respect of the 10,000,000 founder shares held by them if KVSB fails to complete a business combination within the required period. Additionally, in such event, the 1,132,688 private placement shares purchased by the Sponsor simultaneously with the consummation of the initial public offering for an aggregate purchase price of $11.3 million, will also expire worthless. Mr. Kaul, KVSB's Chairman and Chief Executive Officer, also has an economic interest in such private placement shares and in the 9,880,000 founder shares owned by the Sponsor. The 10,232,269shares of New Nextdoor Class B common stock into which the 9,880,000 founder shares held by the Sponsor will automatically convert and be exchanged in connection with the Merger, if unrestricted, fully vested and freely tradable, would have had an aggregate market value of approximately $ million based upon the closing price of $ per share on Nasdaq on , 2021, the most recent practicable date prior to the date of this proxy statement/prospectus. However, given that such shares of New Nextdoor Class B common stock will be subject to certain lock-up restrictions, KVSB believes such shares may have less value. The 176,334shares of New Nextdoor Class B common stock into which the 120,000 founder shares held by KVSB's independent directors will automatically convert and be exchanged in connection with the Merger, if unrestricted and freely tradable, would have had an aggregate market value of approximately $ million based upon the closing price of $ per share on the Nasdaq on , 2021, the most recent practicable date prior to the date of this proxy statement/prospectus. The 1,132,688 shares of New Nextdoor Class B common stock representing the 1,132,688 private placement shares held by the Sponsor (after exchange), if unrestricted and freely tradable, would have had an aggregate market value of approximately $ million based upon the closing price of $ per share on the Nasdaq on , 2021, the most recent practicable date prior to the date of this proxy statement/prospectus. The Sponsor Related PIPE Investors have subscribed for $7,500,000 of the PIPE Investment, for which they will receive 750,000 shares of New Nextdoor Class A common stock, which, if unrestricted and freely tradable, would have had an aggregate market value of approximately $ million based upon the closing price of $ per share on Nasdaq on , 2021, the most recent practicable date prior to the date of this proxy statement/prospectus. Based on the difference in the purchase price of $0.0025 that the Sponsor paid for the founder shares, as compared to the purchase price of $10.00 per share of KVSB Class A common stock sold in the initial public offering, the Sponsor and its affiliates may earn a positive rate of return on their investment even if the share price of New Nextdoor Class A common stock after the Closing falls below the price initially paid for the KVSB Class A common stock in the initial public offering and the public stockholders experience a negative rate of return on their investment following the Closing of the Business Combination.

•The Sponsor (including its representatives and affiliates) and KVSB's directors and officers, are, or may in the future become, affiliated with entities that are engaged in a similar business to KVSB. For example, certain officers and directors of KVSB, who may be considered an affiliate of the Sponsor, have also recently incorporated Khosla Ventures Acquisition Co. I ('KVSA'), Khosla Ventures Acquisition Co. III ('KVSC') and Khosla Ventures Acquisition Co. IV ('KVSD'), each of which is a blank check company incorporated as a Delaware corporation for the purpose of effecting their respective initial business combinations. Mr. Kaul is Chairman and Chief Executive Officer and Mr. Buckland is Chief Operating Officer, Chief Financial Officer, Treasurer and Secretary of each of KVSB, KVSC and KVSD. Additionally, Mr. Shklovsky is a director of KVSA. The Sponsor and KVSB's directors and officers are not prohibited from sponsoring, or otherwise becoming involved with, any other blank check companies prior to KVSB completing its initial business combination. Moreover, certain of KVSB's directors and officers have time and attention requirements for investment funds of which affiliates of the Sponsor are the investment managers. KVSB's directors and officers also may become aware of business opportunities which may be appropriate for presentation to KVSB, and the other entities to which they owe certain fiduciary or contractual duties, including KVSA, KVSC and KVSD. Accordingly, they may have had conflicts of interest in determining to which entity a particular business opportunity should be presented. These conflicts may not be resolved in KVSB's favor and such potential business opportunities may be presented to other entities prior to their presentation to KVSB, subject to applicable fiduciary duties under the DGCL. KVSB's Existing Organizational Documents provide that KVSB renounces its interest in any corporate opportunity offered to any director or officer of KVSB.

•The Sponsor Related PIPE Investor has subscribed for $7.5 million of the PIPE Investment, for which they will receive up to 750,000 shares of New Nextdoor Class A common stock. Mr. Kaul has an economic interest in the Sponsor Related PIPE Investor. The 750,000 shares of New Nextdoor Class A common stock which the Sponsor Related PIPE Investor has subscribed for in the PIPE Investment, if unrestricted and freely tradable, would have had an aggregate market value of approximately $ million based upon the closing price of $ per share on the Nasdaq on , 2021, the most recent practicable date prior to the date of this proxy statement/prospectus. See the section entitled 'Certain Relationships and Related Person Transactions - KVSB - Subscription Agreements.'

•KVSB's existing directors and officers will be eligible for continued indemnification and continued coverage under KVSB's directors' and officers' liability insurance after the Merger and pursuant to the Merger Agreement.

•In the event that KVSB fails to consummate a business combination within the prescribed time frame (pursuant to the Existing Organizational Documents), or upon the exercise of a redemption right in connection with the Business Combination, KVSB will be required to provide for payment of claims of creditors that were not waived that may be brought against KVSB within the ten years following such redemption. In order to protect the amounts held in KVSB's trust account, the Sponsor has agreed that it will be liable to KVSB if and to the extent any claims by a third party (other than KVSB's independent auditors) for services rendered or products sold to KVSB, or a prospective target business with which KVSB has discussed entering into a transaction agreement, reduce the amount of funds in the trust account to below (i) $10.00 per public share or (ii) such lesser amount per public share held in the trust account as of the date of the liquidation of the trust account, due to reductions in value of the trust assets, in each case, net of the amount of interest which may be withdrawn to fund KVSB's working capital requirements, subject to an annual limit of $500,000, and/or to pay taxes, except as to any claims by a third party who executed a waiver of any and all rights to seek access to the trust account and except as to any claims under the indemnity of the underwriters of KVSB's initial public offering against certain liabilities, including liabilities under the Securities Act.

these expenses on behalf of KVSB, they are entitled to reimbursement of such payments. However, if KVSB fails to consummate a business combination by the Liquidation Date, they will not have any claim against the trust account for reimbursement. Accordingly, KVSB may not be able to reimburse the expenses advanced by KVSB's officers and directors or their affiliates if the Business Combination, or another business combination, is not completed by the Liquidation Date.

•Pursuant to the Registration Rights Agreement, the Sponsor and the Sponsor Related PIPE Investor will have customary registration rights, including demand and piggy-back rights, subject to cooperation and cut-back provisions with respect to the shares of New Nextdoor common stock held by such parties following the consummation of the Business Combination.

The Sponsor has agreed to vote in favor of the Business Combination, regardless of how our public stockholders vote. Unlike some other blank check companies in which the initial stockholders agree to vote their shares in accordance with the majority of the votes cast by the public stockholders in connection with an initial business combination, the Sponsor and each director of KVSB have agreed to, among other things, vote in favor of the Merger Agreement and the transactions contemplated thereby, in each case, subject to the terms and conditions contemplated by the Sponsor Support Agreement. As of the date of this proxy statement/prospectus, the Sponsor (including KVSB's independent directors) owns issued and outstanding shares of KVSB common stock representing 16.9% of the outstanding voting power on an as-converted basis, and 12.8% of the outstanding voting power on a per actual share basis.

At any time at or prior to the Business Combination, during a period when they are not then aware of any material nonpublic information regarding us or KVSB's securities, the Sponsor, Nextdoor or their directors, officers, advisors or respective affiliates may purchase public shares from institutional and other investors who vote, or indicate an intention to vote, against any of the Condition Precedent Proposals, or execute agreements to purchase such shares from such investors in the future, or they may enter into transactions with such investors and others to provide them with incentives to acquire public shares or vote their public shares in favor of the Condition Precedent Proposals. Such a purchase may include a contractual acknowledgement that such stockholder, although still the record holder of KVSB's shares, is no longer the beneficial owner thereof and therefore agrees not to exercise its redemption rights. In the event that the Sponsor, Nextdoor or their directors, officers, advisors or respective affiliates purchase shares in privately negotiated transactions from public stockholders who have already elected to exercise their redemption rights, such selling stockholder would be required to revoke their prior elections to redeem their shares. The purpose of such share purchases and other transactions would be to increase the likelihood of (1) satisfaction of the requirement that the BCA Proposal, the Charter Proposal, the Equity Incentive Plan Proposal, the ESPP Proposal and the Adjournment Proposal by a requisite vote of our stockholders, (2) satisfaction of the Minimum Cash Condition, (3) otherwise limiting the number of public shares electing to redeem and (4) KVSB's net tangible assets (as determined in accordance with Rule 3a51(g)(1) of the Exchange Act) being at least $5,000,001.

Entering into any such arrangements may have a depressive effect on the common stock (e.g., by giving an investor or holder the ability to effectively purchase shares at a price lower than market, such investor or holder may therefore become more likely to sell the shares he or she owns, either at or prior to the Business Combination). If such transactions are effected, the consequence could be to cause the Business Combination to be consummated in circumstances where such consummation could not otherwise occur. Purchases of shares by the persons described above would allow them to exert more influence over the approval of the proposals to be presented at the special meeting and would likely increase the chances that such proposals would be approved. KVSB will file or submit a Current Report on Form 8-K to disclose any material arrangements entered into or significant purchases made by any of the aforementioned persons that would affect the vote on the proposals to be put to the special meeting or the redemption threshold. Any such report will include descriptions of any arrangements entered into or significant purchases by any of the aforementioned persons.

Combination that may conflict with your interests as a stockholder. See the section entitled 'BCA Proposal - Interests of KVSB's Directors and Executive Officers in the Business Combination' for a further discussion of these considerations.

Interests of Nextdoor's Directors and Executive Officers in the Business Combination

When you consider the recommendation of the KVSB Board in favor of approval of the BCA Proposal, you should keep in mind that Nextdoor's directors and executive officers may have interests in such proposal that are different from, or in addition to, those of KVSB stockholders generally. These interests include, among other things, the interests listed below:

•Sarah Friar. Ms. Friar, Nextdoor's Chief Executive Officer and President, has agreed to subscribe for and purchase 500,000 shares of New Nextdoor Class A common stock at $10.00 per share in the PIPE Investment on the same terms and conditions as the other PIPE Investors, for aggregate proceeds of $5,000,000. Such shares of New Nextdoor Class A common stock would have had an estimated aggregate value of $ based on the closing price of $ per public share on Nasdaq on , 2021, the closing price on the record date. In addition, in March 2021, Ms. Friar was granted a stock option award to purchase 743,184 shares of Nextdoor common stock, with an aggregate grant date fair value of $8,513,428, which will vest upon closing of the Business Combination, subject to Ms. Friar's continuous employment through such date.

•Severance Agreements. Prior to the Business Combination it is expected that New Nextdoor will enter into individual change-in-control and severance agreements ('Severance Agreements') with the current executive officers of Nextdoor. Under each Severance Agreement, the applicable executive officer who is terminated by New Nextdoor without cause or who resigns for good reason outside of a change in control (each such term as defined in each Severance Agreement) will receive, in exchange for a customary release of claims: (i) a severance payment of six months base salary in a cash lump sum and (ii) payment of premiums for continued medical benefits for up to six months following termination. In addition, if an executive officer's employment is terminated by New Nextdoor without cause or by an executive for good reason within the three months preceding a change in control (but after a legally binding and definitive agreement for a potential change of control has been executed) or within the twelve months following a change in control, the Severance Agreements provide the following benefits in exchange for a customary release of claims: (i) a severance payment of twelve months' base salary and then-current target bonus opportunity at 100% achievement of target paid in a cash lump sum, (ii) full acceleration of time-vesting equity awards and accelerated vesting of performance-vesting equity awards at the greater of (x) actual performance through the date of termination or (y) target level (unless an individual equity award agreement provides otherwise), and (iii) payment of premiums for continued medical benefits for up to twelve months following termination. See the section entitled 'Management of New Nextdoor Following the Business Combination - Executive Offer Letters - Severance Agreements' for further discussion.

Recommendation to Stockholders of KVSB

The KVSB Board believes that the BCA Proposal and the other proposals to be presented at the special meeting are in the best interest of KVSB's stockholders and unanimously recommends that its stockholders vote 'FOR' the BCA Proposal, 'FOR' the Stock Issuance Proposal, 'FOR' the Charter Proposal, 'FOR' the Advisory Charter Amendment Proposals, 'FOR' the Equity Incentive Plan Proposal, 'FOR' the ESPP Proposal and 'FOR' the Adjournment Proposal, in each case, if presented to the special meeting.

Sources and Uses of Funds for the Business Combination

The following table summarizes the sources and uses for funding the Business Combination. These figures assume that (i) no public stockholders exercise their redemption rights in connection with the Business Combination or our extension proposal, (ii) all outstanding shares of capital stock of Nextdoor will be cancelled in exchange for the right to receive an aggregate of 302,532,879 shares of New Nextdoor Class B common stock (at a deemed value of $10.00 per share) and (iii) all outstanding Nextdoor Awards outstanding as of immediately prior to the Closing will be converted into awards to purchase an aggregate of 47,698,062 shares of New Nextdoor Class B common stock (at a deemed value of $10.00 per share and a weighted-average exercise price for the New Nextdoor Options of $2.35 per share after giving effect to the Exchange Ratio and assuming that all Nextdoor Awards are net settled) and 180,503 shares of New Nextdoor Class B common stock will be reserved for issuance pursuant to the Pixel Labs Merger Agreement, representing a pre-transaction equity value of Nextdoor of $3.5 billion. If the actual facts are different from these assumptions, the below figures will be different.


Sources	Uses
($ in millions)
Cash and investments held in trust account(1)	$	416	Equity consideration to Nextdoor Stockholders	$	3,500
PIPE Investment(2)	270	Cash to balance sheet	639
Nextdoor rollover equity	3,500	Estimated transaction expenses(3)	47
Total sources	$	4,186	Total uses	$	4,186

__________________

(1)Calculated as of August 31, 2021 and based on the assumptions noted above the table.

(2)Shares issued in the PIPE Investment are at a deemed value of $10.00 per share.

(3)Includes deferred underwriting commission of $14.6 million. Such deferred underwriting commissions are equal to 3.5% of the aggregate proceeds of the initial public offering of KVSB, and will be payable if and when a Business Combination is consummated. Such deferred underwriting commission will not otherwise be adjusted based on the amount of redemptions. Assuming the maximum redemptions of an aggregate of $249.3 million (which is derived from the number of shares that could be redeemed in connection with the Transactions at an assumed redemption price of approximately $10.00 per share based on funds held in the trust account as of June 30, 2021 and still satisfy the Minimum Cash Condition required to consummate the Transactions of at least $400.0 million, after giving effect to the (i) proceeds from the PIPE Investment, (ii) payment of the estimated transaction costs incurred in connection with the Transactions of $47.0 million, including deferred underwriting commissions and unpaid offering costs from KVSB's initial public offering, and (iii) proceeds of $10.0 million from the Sponsor Forward Purchase Agreement), such deferred underwriting commissions would represent approximately 8.7% of the net proceeds of the initial public offering of KVSB after giving effect to such redemptions. Assuming redemptions of an aggregate of $124.7 million (which is half of the maximum redemptions set forth above), such deferred underwriting commissions would represent approximately 5.0% of the net proceeds of the initial public offering of KVSB after giving effect to such redemptions.

U.S. Federal Income Tax Considerations-Material U.S. Federal Income Tax Consequences of the Merger

Nextdoor and KVSB intend for the Merger to qualify as a 'reorganization' within the meaning of Section 368(a) of the Code. In connection with the filing of this registration statement, Nextdoor is receiving an opinion of legal counsel, based on certain factual representations from Nextdoor and KVSB and certain customary factual assumptions, to the effect that the Merger will qualify as a 'reorganization.' It is not, however, a condition to the completion of the Merger that any of the parties receive an opinion of counsel as to the tax consequences of the Merger. Further, no ruling has been, or will be, sought by Nextdoor or KVSB from the IRS with respect to the Merger and there can be no assurance that the IRS will not challenge the qualification of the Merger as a 'reorganization' under Section 368(a) of the Code or that a court would not sustain such a challenge.

Assuming that the Business Combination qualifies as a reorganization under the provisions of section 368(a) of the Code, the following tax consequences generally will result to U.S. Holders who exchange stock of Nextdoor for New Nextdoor Class B common stock:

U.S. Holders receiving New Nextdoor Class B common stock in exchange for common stock of Nextdoor will recognize neither gain nor loss. The aggregate tax basis of the New Nextdoor Class B common stock received by a U.S. Holder in the Merger generally will be the same as the aggregate tax basis of common stock of Nextdoor surrendered in exchange therefor. The holding period of New Nextdoor Class B common stock received by a U.S. Holder in the Merger will include the holding period of the common stock of Nextdoor surrendered therefor by the

U.S. Holder in the Merger. The tax consequences of the transactions to each Nextdoor stockholder may depend on such holder's particular facts and circumstances. Nextdoor stockholders should consult with their tax advisors regarding the tax consequences of the Merger and the requirements that must be satisfied in order for the Merger to qualify as a reorganization under Section 368(a) of the Code. For more information, please see 'U.S. Federal Income Tax Considerations-Material U.S. Federal Income Tax Consequences of the Merger.'

Expected Accounting Treatment of the Transactions

The Business Combination

We expect the Transactions to be accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, KVSB is expected to be treated as the 'acquired' company for financial reporting purposes. Accordingly, the Transactions are expected to be reflected as the equivalent of Nextdoor issuing stock for the net assets of KVSB, accompanied by a recapitalization. The net assets of KVSB will be stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Transactions will be those of Nextdoor. See the sections entitled 'BCA Proposal - Expected Accounting Treatment of the Business Combination' and 'Unaudited Pro Forma Condensed Combined Financial Information.'

Regulatory Matters

Under the HSR Act and the rules that have been promulgated thereunder by the Federal Trade Commission (''FTC''), certain transactions may not be consummated unless information has been furnished to the Antitrust Division of the Department of Justice ('Antitrust Division') and the FTC and certain waiting period requirements have been satisfied. The Business Combination is subject to these requirements and may not be completed until the expiration of a 30-day waiting period following the two filings of the required Notification and Report Forms with the Antitrust Division and the FTC or until early termination is granted. On July 19, 2021, KVSB and Nextdoor filed the required forms under the HSR Act with respect to the Business Combination with the Antitrust Division and the FTC and requested early termination. The waiting period expired at 11:59 p.m. (ET) on August 18, 2021.

At any time before or after consummation of the Business Combination, notwithstanding termination of the respective waiting periods under the HSR Act, the Department of Justice or the FTC, or any state or foreign governmental authority could take such action under applicable antitrust laws as such authority deems necessary or desirable in the public interest, including seeking to enjoin the consummation of the Business Combination, conditionally approving the Business Combination upon divestiture of assets, subjecting the completion of the Business Combination to regulatory conditions or seeking other remedies. Private parties may also seek to take legal action under the antitrust laws under certain circumstances. KVSB cannot assure you that the Antitrust Division, the FTC, any state attorney general or any other government authority will not attempt to challenge the Business Combination on antitrust grounds, and, if such a challenge is made, KVSB cannot assure you as to its result.

None of KVSB nor Nextdoor are aware of any material regulatory approvals or actions that are required for completion of the Business Combination other than the expiration or early termination of the waiting period under the HSR Act. It is presently contemplated that if any such additional regulatory approvals or actions are required, those approvals or actions will be sought. There can be no assurance, however, that any additional approvals or actions will be obtained.

Emerging Growth Company

KVSB is an 'emerging growth company,' as defined in Section 2(a) of the Securities Act, as modified by the JOBS Act, and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in KVSB's periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

Further, section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. KVSB has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, KVSB, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of KVSB's financial statements with certain other public companies difficult or impossible because of the potential differences in accounting standards used.

We will remain an emerging growth company until the earlier of: (1) the last day of the fiscal year (a) following the fifth anniversary of the closing of KVSB's initial public offering, (b) in which we have total annual gross revenue of at least $1.07 billion or (c) in which we are deemed to be a large accelerated filer, which means the market value of our common equity that is held by non-affiliates exceeds $700 million as of the end of the prior fiscal year's second fiscal quarter; and (2) the date on which we have issued more than $1.00 billion in non-convertible debt securities during the prior three-year period. References herein to 'emerging growth company' shall have the meaning associated with it in the JOBS Act.

Risk Factors

In evaluating the proposals to be presented at the KVSB special meeting, a stockholder should carefully read this proxy statement/prospectus and especially consider the factors discussed in the section entitled 'Risk Factors.' Such risks include, but are not limited to:

Risks Related to Nextdoor's Business and Industry

•Nextdoor has a limited operating history at the current scale of its business and is still scaling up its monetization efforts, which makes it difficult to evaluate its current business and future prospects, and there is no assurance it will be able to scale its business for future growth.

•Nextdoor currently generates substantially all of its revenue from advertising. If advertisers reduce or eliminate their spending with Nextdoor, Nextdoor's business, operating results, and financial condition would be adversely impacted.

•Nextdoor's ability to attract and retain advertisers depends on its ability to collect and use data and develop products to enable it to effectively deliver and accurately measure advertisements on the Nextdoor platform.

•Nextdoor's business is highly competitive. Competition presents an ongoing threat to the success of Nextdoor's business.

•Nextdoor's business is dependent on its ability to maintain and scale its product offerings and technical infrastructure, and any significant disruption in the availability of Nextdoor's platform could damage Nextdoor's reputation, result in a potential loss of neighbors and engagement, and adversely affect Nextdoor's business, operating results, and financial condition.

•If Nextdoor's efforts to build strong brand identity and reputation are not successful, it may not be able to attract or retain neighbors, and its business, operating results, and financial condition will be adversely affected.

•Health epidemics, including the COVID-19 pandemic have had or could have an adverse impact on Nextdoor's business, operations and the markets and communities in which Nextdoor, its partners and its customers operate. In addition, during the COVD-19 pandemic, Nextdoor experienced an increase in

neighbor growth and engagement and there is no guarantee that Nextdoor will be able to maintain its neighbor growth and engagement as the COVID-19 pandemic subsidies.

•Nextdoor plans to continue expanding its international operations where it has limited operating experience and may be subject to increased business, regulatory and economic risks that could seriously harm its business, operating results, and financial condition.

•Nextdoor plans to continue to make acquisitions, which could harm its financial condition or results of operations and may adversely affect the price of its Class A common stock.

•Nextdoor's business depends largely on its ability to attract and retain talented employees, including senior management. If Nextdoor loses the services of Sarah Friar, its Chief Executive Officer, or other members of its senior management team, Nextdoor may not be able to execute on its business strategy.

•Nextdoor is dependent on third-party software and service providers, including the Google Ad Manager ('GAM') platform, for management and delivery of advertisements on the Nextdoor platform. Any failure or interruption experienced by such third-parties, including as a result of the COVID-19 pandemic, could result in the inability of certain businesses to advertise on Nextdoor's platform, and adversely impact Nextdoor's business, operating results, and financial condition.

•Nextdoor relies on third-party software and service providers, including Amazon Web Services ('AWS'), to provide systems, storage and services for its platform. Any failure or interruption experienced by such third parties, including as a result of the COVID-19 pandemic, could result in the inability of neighbors and advertisers to access or utilize Nextdoor's platform, and adversely impact Nextdoor's business, operating results, and financial condition.

•Technologies have been developed that can block the display of advertisements on the Nextdoor platform, which could adversely impact its business, operating results, and financial condition.

•Distribution and marketing of, and access to, Nextdoor's platform depends, in significant part, on a variety of third-party publishers and platforms (including mobile app stores, third-party payment providers, computer systems, and other communication systems and service providers). If these third parties limit, prohibit or otherwise interfere with or change the terms of the distribution, use or marketing of Nextdoor's platform in any material way, it could materially adversely affect Nextdoor's business, operating results, and financial condition.

•Nextdoor's ability to use its U.S. federal and state net operating losses to offset future taxable income may be subject to certain limitations which could subject Nextdoor's business to higher tax liability.

•Taxing authorities in the U.S. and in foreign jurisdictions may successfully assert that Nextdoor should have collected or in the future should collect sales and use, gross receipts, value-added or similar taxes, and may successfully impose additional obligations on Nextdoor, and any such assessments or obligations could adversely affect Nextdoor's business, operating results, and financial condition.

•Nextdoor's use of 'open source' software could subject it to possible litigation or could prevent it from offering products that include open source software or require it to obtain licenses on unfavorable terms.

Risks Related to the Business Combination and KVSB, and SPACs Generally

•Neither the KVSB board of directors nor any committee thereof obtained a third-party valuation in determining whether or not to pursue the Business Combination.

•Since the Sponsor and KVSB's directors and executive officers have interests that are different, or in addition to (and which may conflict with), the interests of our stockholders, a conflict of interest may have existed in determining whether the Business Combination with Nextdoor is appropriate as our initial business combination. Such interests include that Sponsor will lose its entire investment in us if our business combination is not completed.

•Future resales of common stock after the consummation of the Business Combination may cause the market price of New Nextdoor's securities to drop significantly, even if New Nextdoor's business is doing well.

•New Nextdoor may be subject to securities litigation, which is expensive and could divert management attention.

•The dual class structure of New Nextdoor's common stock will have the effect of concentrating voting power with Nextdoor's management and other existing stockholders, which will limit your ability to influence the outcome of important transactions, including a change in control.

Key Business Metrics and Non-GAAP Financial Measure

In addition to its financial results, Nextdoor uses the following business metrics to evaluate its business, measure its performance, identify trends affecting its business, and make strategic decisions. Nextdoor also uses Adjusted EBITDA, which is a non-GAAP financial measure, as part of its overall assessment of Nextdoor's performance, including the preparation of its annual operating budget and quarterly forecasts, to evaluate the effectiveness of its business strategies and to communicate with its board of directors concerning our financial performance. For additional information regarding these measures, see the sections entitled 'Nextdoor's Management's Discussion and Analysis of Financial Condition and Results of Operations-Key Business Metrics' and 'Nextdoor's Management's Discussion and Analysis of Financial Condition and Results of Operations-Non-GAAP Financial Measure.'

SELECTED UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The selected unaudited pro forma condensed combined financial information (the 'Selected Pro Forma Information') gives effect to the Transactions and the other related events described in the section entitled 'Unaudited Pro Forma Condensed Combined Financial Information.' The Transactions are expected to be accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, KVSB is expected to be treated as the 'acquired' company for financial reporting purposes. Accordingly, the Transactions will be reflected as the equivalent of Nextdoor issuing common stock for the net assets of KVSB, accompanied by a recapitalization. The net assets of KVSB will be stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Transactions will be those of Nextdoor in future reports of New Nextdoor.

The selected unaudited pro forma condensed combined balance sheet data as of June 30, 2021 gives pro forma effect to the Transactions and the other related events as if consummated on June 30, 2021. The selected unaudited pro forma condensed combined statements of operations data for the six months ended June 30, 2021 and for the year ended December 31, 2020 give effect to the Transactions and the other related events as if consummated on January 1, 2020, the beginning of the earliest period presented.

The following Selected Pro Forma Information has been prepared in accordance with Article 11 of Regulation S-X as amended by the final rule, Release No. 33-10786 'Amendments to Financial Disclosures about Acquired and Disposed Businesses' and should be read in conjunction with the more detailed unaudited pro forma condensed combined financial information of New Nextdoor appearing elsewhere in this proxy statement/prospectus and the accompanying notes in the section entitled 'Unaudited Pro Forma Condensed Combined Financial Information.' The unaudited pro forma condensed combined financial information is derived from and should be read in conjunction with the historical financial statements and accompanying notes of KVSB and Nextdoor for the applicable periods included elsewhere in this proxy statement/prospectus. The Selected Pro Forma Information has been presented for informational purposes only and is not necessarily indicative of what New Nextdoor's financial position or results of operations actually would have been had the Transactions and the other related events been completed as of the dates indicated. The Selected Pro Forma Information does not purport to project the financial position or operating results of New Nextdoor that may be expected for any other period in the future.

The unaudited pro forma condensed combined financial information has been prepared using the assumptions below with respect to the potential redemption by KVSB's public stockholders of shares of KVSB's Class A common stock for cash equal to their pro rata portion of the aggregate amount on deposit (as of two business days prior to the Closing) in the trust account:

•Assuming No Redemptions: this scenario assumes that no public stockholders of KVSB exercise their redemption rights with respect to their public shares of KVSB's Class A common stock for a pro rata portion of the funds in the trust account; and

•Assuming Maximum Redemptions: this scenario assumes 24,932,638 public shares of KVSB's Class A common stock are redeemed for an aggregate payment of $249.3 million, which is derived from the number of shares that could be redeemed in connection with the Transactions at an assumed redemption price of approximately $10.00 per share based on funds held in the trust account as of June 30, 2021 and still satisfy the Minimum Cash Condition required to consummate the Transactions of at least $400.0 million, after giving effect to the (i) proceeds from the PIPE Investment, (ii) payment of the estimated transaction costs incurred in connection with the Transactions of $47.0 million, including deferred underwriting commissions and unpaid offering costs from KVSB's initial public offering, and (iii) proceeds of $10.0 million from the Sponsor Forward Purchase Agreement.

The following summarizes the pro forma New Nextdoor common stock issued and outstanding immediately after the Transactions and the other related events, based on Nextdoor's capitalization as of August 31, 2021, presented under the two assumed redemption scenarios:

RISK FACTORS

KVSB stockholders should carefully consider the following risk factors, together with all of the other information included in this proxy statement/prospectus, before they decide whether to vote or instruct their vote to be cast to approve the relevant proposals described in this proxy statement/prospectus.

Unless the context otherwise requires, all references in this subsection to the 'Company,' 'we,' 'us' or 'our' refer to the business of Nextdoor, Inc. and its subsidiaries prior to the consummation of the Business Combination, which will be the business of New Nextdoor and its subsidiaries following the consummation of the Business Combination.

Risks Related to Nextdoor's Business and Industry

Nextdoor has a limited operating history at the current scale of its business and is still scaling up its monetization efforts, which makes it difficult to evaluate its current business and future prospects, and there is no assurance it will be able to scale its business for future growth.

Nextdoor commenced operating the Nextdoor platform in 2011 and began supporting the platform with advertising in 2016. Nextdoor's limited operating history at the current scale of its business may make it difficult to evaluate its current business and future prospects. Nextdoor has encountered, and will continue to encounter, risks and difficulties frequently experienced by growing companies in rapidly evolving industries, including challenges in accurate financial planning and forecasting, increasing competition and expenses as Nextdoor continues to grow its business, and Nextdoor's ability to achieve market acceptance of its platform and attract, engage and retain users, who Nextdoor calls 'neighbors' (which includes individuals) and organizations (which includes businesses and public agencies, including paying customers such as advertisers). You should consider Nextdoor's business and prospects in light of the risks and difficulties that it may encounter as a business with a limited operating history. Nextdoor cannot ensure that it will be successful in addressing these and other challenges Nextdoor may face in the future, and Nextdoor's business, operating results, and financial condition may be adversely affected if it does not manage these risks successfully. Nextdoor may not be able to maintain its current rate of growth, which is a risk characteristic often shared by companies with limited operating histories participating in rapidly evolving industries.

Additionally, Nextdoor is still in the early stages of monetizing its platform. Nextdoor's growth strategy depends on, among other things, increasing neighbors on the network, increasing engagement, developing new and improving existing products for neighbors and organizations, attracting more advertisers (including expanding its sales efforts to reach advertisers in additional international markets), scaling its business with existing advertisers, and delivering targeted advertisements based on neighbors' personal taste and interests. There can be no assurance that Nextdoor will successfully increase monetization on its platform or that it will sustain or increase the current growth rate of its revenue.

Nextdoor currently generates substantially all of its revenue from advertising. If advertisers reduce or eliminate their spending with Nextdoor, Nextdoor's business, operating results, and financial condition would be adversely impacted.

Substantially all of Nextdoor's revenue is currently generated from the sales of advertising on its platform in the form of online display advertisements, which include sponsored posts, local deals, and neighborhood sponsorships. Nextdoor's advertisers typically do not have long-term advertising spend commitments with Nextdoor. Many of Nextdoor's advertisers spend only a relatively small portion of their overall advertising budget with Nextdoor. In addition, advertisers may view some of the features on Nextdoor's platform as experimental and unproven. Advertisers will not continue to do business with Nextdoor, or they will reduce the prices they are willing to pay to advertise with Nextdoor, if Nextdoor does not deliver advertisements in an effective manner, or if advertisers do not believe that their investment in advertising with Nextdoor will generate a competitive return relative to alternatives. Nextdoor's ability to attract and retain advertisers, and ultimately generate revenue, may be adversely affected by a number of factors, including but not limited to:

•decreases in neighbor and advertiser engagement on the platform;

•slower than anticipated growth in, or lack of growth or decreases in, the number of neighbors on the platform;

•platform changes (such as the migration to Nextdoor's proprietary ad server) or inventory management decisions that change the size, format, frequency, or relative prominence of advertisements displayed on the platform;

•competitors offering more attractive pricing for advertisements than Nextdoor is unable or unwilling to match;

•a decrease in the quantity or quality of advertisements shown to neighbors;

•changes to third-party policies or applications that limit Nextdoor's ability to deliver, target, or measure the effectiveness of advertising, including changes by mobile operating system and browser providers such as Apple and Google;

•changes to demographics of Nextdoor's neighbors that make Nextdoor less attractive to advertisers;

•neighbors that upload content or take other actions that are deemed to be hostile, inappropriate, illicit, objectionable, illegal, or otherwise not consistent with the brand of Nextdoor's advertisers;

•adverse government actions or legislative, regulatory, or other legal developments;

•neighbor behavior or changes to the platform that may affect, among other things, the safety and security of other neighbors or the cultivation of a positive and inclusive online community;

•adverse media reports or other negative publicity involving Nextdoor;

•Nextdoor implementing or enforcing policies, such as advertising policies, community guidelines, and other terms or service that are perceived negatively by advertisers;

•Nextdoor's ability to develop and improve its products for advertisers;

•limitations in, or reductions to, the availability, accuracy, utility, and security of analytics and measurement solutions offered by Nextdoor or third parties that are intended to demonstrate the value of Nextdoor's advertisements to advertisers;

•changes to Nextdoor's data privacy practices that affect the type or manner of advertising that Nextdoor is able to provide, including as a result of changes to laws, regulations or regulatory actions, such as the European General Data Protection Regulation ('GDPR'), European ePrivacy Directive, UK General Data Protection Regulation ('UK GDPR'), UK Data Protection Act 2018, California Consumer Privacy Act ('CCPA'), the California Privacy Rights Act ('CPRA') or changes to third-party policies; and

•the impact of macroeconomic conditions, whether in the advertising industry in general, among specific types of advertisers or within particular geographies.

From time to time, certain of these factors have adversely affected Nextdoor's revenue to varying degrees. For example, during the second quarter of 2020, advertisers reduced their advertising spend with Nextdoor as a result of the impact of the COVID-19 pandemic on global macroeconomic conditions and on the advertising industry in general. The occurrence of any of these or other factors in the future could result in a reduction in demand for Nextdoor's advertisements, which may reduce the prices Nextdoor receives for its advertisements, or cause advertisers to stop or reduce their spend with Nextdoor, either of which would negatively affect Nextdoor's business, operating results, and financial condition. Similar occurrences in the future may impair Nextdoor's ability to maintain or increase the quantity or quality of advertisements shown to neighbors and adversely affect Nextdoor's business, operating results, and financial condition.

Nextdoor's ability to attract and retain advertisers depends on its ability to collect and use data and develop products to enable it to effectively deliver and accurately measure advertisements on the Nextdoor platform.

Most advertisers rely on tools that measure the effectiveness of their advertising campaigns in order to allocate their advertising spend among various formats and platforms. If Nextdoor is unable to accurately measure the effectiveness of advertising on its platform, if at all, or if Nextdoor is unable to convince advertisers that its platform should be part of a larger advertising budget, Nextdoor's ability to increase the demand and pricing of its advertising tools and maintain or scale its revenue may be limited or decline. Nextdoor's ability to develop and offer products that accurately measure the effectiveness of a campaign on its platform is critical to its ability to attract new advertisers and retain, and increase spend from, its existing advertisers.

Nextdoor is continually developing and improving its products for advertisers and such efforts have and are likely to continue to require significant time and resources and additional investment, and in some cases Nextdoor has relied on, and may in the future rely on, third parties to provide data and technology needed to provide certain measurement data to its advertisers. If Nextdoor cannot continue to develop and improve its products for advertisers in a timely fashion, those products are not reliable, or the measurement results are inconsistent with advertiser's expectations or goals, Nextdoor's revenue could be adversely affected.

In addition, web and mobile browser developers, such as Apple, Microsoft or Google, have implemented and may continue to implement changes, including requiring additional user permissions, in their browser or device operating system that impair Nextdoor's ability to measure and improve the effectiveness of advertising on its platform. Such changes include limiting the use of first-party and third-party cookies and related tracking technologies, such as mobile advertising identifiers, and other changes that limit Nextdoor's ability to collect information that allows it to attribute neighbors' actions on advertisers' websites to the effectiveness of advertising campaigns run on Nextdoor's platform. For example, Apple launched its Intelligent Tracking Prevention ('ITP') feature in its Safari browser. ITP blocks some or all third-party cookies by default on mobile and desktop and ITP has become increasingly restrictive over time. Apple's related Privacy-Preserving Ad Click attribution, intended to preserve some of the functionality lost with ITP, would limit cross-site and cross-device attribution, prevent measurement outside a narrowly-defined attribution window, and prevent advertisement re-targeting and optimization. Further, Apple introduced an App Tracking Transparency framework that limits the ability of mobile applications to request an iOS device's advertising identifier and may also affect Nextdoor's ability to track neighbors' actions off its platform and connect their interactions with on-platform advertising. Similarly, Google recently announced that it plans to stop supporting third-party cookies in its Google Chrome browser. These web and mobile browser developers have also implemented and may continue to implement changes and restrictions in browser or device functionality that limit Nextdoor's ability to communicate with or understand the identity of its neighbors.

These restrictions and changes make it more difficult for Nextdoor to provide the most relevant advertisements to its neighbors, as well as decrease its ability to measure the effectiveness of, re-target or optimize advertising on its platform. Developers may release additional technology that further inhibits Nextdoor's ability to collect data that allows Nextdoor to measure the effectiveness of advertising on its platform. Any other restriction, whether by law, regulation, policy (including third-party policies) or otherwise, on Nextdoor's ability to collect and share data which its advertisers find useful or that further reduce its ability to measure the effectiveness of advertising on its platform, would impede Nextdoor's ability to attract, grow and retain advertisers. Advertisers and other third parties who provide data that helps Nextdoor deliver personalized, relevant advertising may restrict or stop sharing this data and it therefore may not be possible for Nextdoor to collect this data within the platform or from another source.

Nextdoor relies heavily on its ability to collect and share data and metrics for its advertisers to help new and existing advertisers understand the performance of advertising campaigns. If advertisers do not perceive Nextdoor's metrics to be accurate representations of its neighbors and neighbor engagement, or there are inaccuracies in Nextdoor's metrics, advertisers may decrease or eliminate allocations of their budgets or resources to Nextdoor's platform, which could harm its business, operating results, and financial condition.

If Nextdoor fails to add new neighbors or retain current neighbors, or if current neighbors engage less with Nextdoor, its business, operating results, and financial condition would be adversely impacted.

The number of neighbors that use the Nextdoor platform and their level of engagement on the platform are critical to Nextdoor's success. Nextdoor must continue to engage and retain existing neighbors on its platform as well as attract, engage and retain new neighbors. The number of neighbors on Nextdoor may not continue to grow at the current growth rate, if at all, and it may even decline. In order to attract new neighbors, Nextdoor must engage with neighbors in existing neighborhoods on its platform and add new neighborhoods to the Nextdoor platform, both domestically and internationally. If Nextdoor's neighbor growth rate slows or reverses, its financial performance will be adversely impacted unless Nextdoor can increase its engagement with its existing neighbors and its monetization efforts to offset any such reduction or decrease in neighborhood growth rate. Moreover, Nextdoor is unable to predict the continued impact of the COVID-19 pandemic on neighbor growth and engagement with any certainty, and Nextdoor expects these trends to continue to be subject to volatility.

If current and potential neighbors do not perceive their experience with Nextdoor's platform to be useful, the content generated on the platform to be valuable or relevant or the social connections with fellow neighbors to be worthwhile, Nextdoor may not be able to attract new neighbors, retain existing neighbors or maintain or increase the frequency and duration of their engagement on its platform. In addition, if Nextdoor's existing neighbors decrease the frequency or duration of their engagement or the growth rate of its neighbor base slows or reverses, Nextdoor may be required to incur significantly higher marketing expenses than it currently anticipates in order to acquire new neighbors or retain current neighbors.

There are many factors that could negatively impact Nextdoor's ability to grow, retain and engage current and prospective neighbors, including but not limited to:

•neighbors increasing their engagement with competitor's platforms, products or services instead of, or more frequently than, Nextdoor's platform;

•changes in the amount of time neighbors spend across all applications and platforms, including Nextdoor's platform;

•Nextdoor failing to introduce platform enhancements that neighbors find engaging or if Nextdoor introduces new features, terms, policies or procedures, or make changes to its platform, that are not favorably received by current or prospective neighbors;

•technical or other problems frustrating the neighbor experience, such as problems that prevent Nextdoor from delivering its service in a fast and reliable manner;

•neighbors having difficulty installing, updating or otherwise accessing the Nextdoor platform on mobile devices through the app or web browsers;

•neighbor behavior on Nextdoor's platform changing, including a decrease in the quality and frequency of content shares on the platform;

•decreases in neighbor or advertiser sentiment due to questions about the quality or usefulness of Nextdoor's platform, concerns about the nature of content made available on the platform, concerns related to privacy, safety, security, well-being or other factors;

•changes mandated by legislation, government and regulatory authorities, or litigation that adversely impact Nextdoor's platform or neighbors;

•third parties preventing their content from being displayed on the Nextdoor platform;

•Nextdoor makes changes to how it promotes different features on its platform;

•initiatives designed to attract and retain neighbors and engagement are unsuccessful or discontinued, whether as a result of actions by Nextdoor, third parties, or otherwise;

•Nextdoor, or other partners and companies in the industry are the subject of adverse media reports or other negative publicity;

•Nextdoor is unable to combat spam, harassment, cyberbullying or other hostile, inappropriate, abusive or offensive content or usage on its platform; or

•Nextdoor cannot preserve and enhance its brand and reputation as a trusted neighborhood networking community.

Any decrease in neighbor growth, retention or engagement could render Nextdoor's service less attractive to neighbors or advertisers, and could harm Nextdoor's business, operating results, and financial condition. In addition, neighbor verification is a critical feature of Nextdoor's platform because it demonstrates that neighbors are real people and businesses in the neighborhood they desire to join. If Nextdoor were to change its verification methods, that may adversely impact Nextdoor's ability to add new neighbors or retain existing neighbors.

Nextdoor's business is highly competitive. Competition presents an ongoing threat to the success of Nextdoor's business.

Nextdoor competes in almost every aspect of its business with companies that provide a variety of internet products, services, content, and online advertising, including from Facebook, Google, Pinterest, Snap, and Twitter. In addition, aspects of Nextdoor's platform compete with other products and services, including real estate, classifieds, and recommendation and search engines. Nextdoor competes with these companies to attract, engage, and retain users and to attract and retain advertisers. If Nextdoor introduces or acquires new products and services or evolves its platform in a way that subjects it to additional competition or as existing competitors introduce new products and services or evolve their platforms, Nextdoor may fail to engage or retain neighbors or attract new neighbors, which could harm Nextdoor's business, operating results, and financial condition.

Some of Nextdoor's current and potential competitors have substantially broader product or service offerings and leverage their relationships based on other products or services to gain additional share of advertising spend. They have large distributed sales forces and an increasing amount of control over mobile distribution channels. Many of these competitors' economies of scale allow them to have access to larger volumes of data and platforms that are used on a more frequent basis than Nextdoor's, which may enable them to better understand their member base and develop and deliver more targeted advertising. Such competitors may not need to rely on third-party data, including data provided by advertisers, to effectively target the campaigns of advertisers, which could make their advertising products more attractive to advertisers than Nextdoor's platform if such third-party data ceases to be available to Nextdoor, whether because of regulatory changes, privacy or cybersecurity concerns or other reasons. If Nextdoor's advertisers do not believe that its value proposition is as compelling as those of Nextdoor's competitors, Nextdoor may not be able to attract new advertisers or retain existing ones, and its business, operating results, and financial condition could be adversely impacted.

Nextdoor's competitors may develop products, features, or services that are similar to Nextdoor's platform or that achieve greater acceptance, may undertake more far-reaching and successful product development efforts or marketing campaigns, or may adopt more aggressive pricing policies. Some competitors may gain a competitive advantage relative to Nextdoor in areas where it operates, including by more effectively responding to changes to third-party products and policies or by integrating competing platforms, applications, or features into products they control such as mobile device operating systems, search engines, browsers, or e-commerce platforms. For example, Apple has introduced changes to iOS 14.5 that limits Nextdoor's ability, and the ability of others in the digital advertising industry, to target and measure advertisements effectively. As a result, Nextdoor's competitors may, and in some cases will, acquire and engage neighbors or generate advertising or other revenue at the expense of Nextdoor's efforts, which would negatively affect Nextdoor's business, operating results, and financial condition. In addition, from time to time, Nextdoor may take actions in response to competitive threats, but it cannot assure you that these actions will be successful or that they will not negatively affect Nextdoor's business, operating results, and financial condition.

Nextdoor believes that its ability to compete depends upon many factors both within and beyond its control, including:

•the popularity, usefulness, ease of use, performance, and reliability of its platform compared to its competitors' products;

•the size and composition of its neighbor base;

•the engagement of neighbors with its platform and competing products;

•first- and third-party data available to Nextdoor relative to its competitors;

•Nextdoor's ability to attract and retain advertisers who use its free or paid advertisements services;

•the timing and market acceptance of developments and enhancements to Nextdoor's platform or its competitors' products;

•Nextdoor's safety and security efforts and its ability to protect neighbor data and to provide neighbors with control over their data;

•Nextdoor's ability to distribute its platform to new and existing neighbors;

•Nextdoor's ability to effectively monetize its platform;

•the successful implementation of platform changes, such as the migration to Nextdoor's proprietary ad server;

•the frequency, size, format, quality, and relative prominence of the advertisements displayed by Nextdoor or its competitors;

•customer service and support efforts;

•marketing and selling efforts, including Nextdoor's ability to measure the effectiveness of its advertisements and to provide advertisers with a compelling return on their investments;

•Nextdoor's ability to establish and maintain publisher interest in integrating their content with its platform;

•changes mandated by legislation, regulatory authorities, or litigation, some of which may have a disproportionate effect on Nextdoor;

•acquisitions or consolidation within Nextdoor's industry, which may result in more formidable competitors;

•Nextdoor's ability to attract, retain, and motivate talented employees, particularly software engineers, designers, and managers;

•Nextdoor's ability to cost-effectively manage and grow its operations; and

•Nextdoor's reputation and brand strength relative to those of its competitors.

If Nextdoor is not able to compete effectively, its neighbor base and level of neighbor engagement may decrease, it may become less attractive to advertisers and its business, operating results, and financial condition may be adversely affected.

Nextdoor's business is dependent on its ability to maintain and scale its product offerings and technical infrastructure, and any significant disruption in the availability of Nextdoor's platform could damage Nextdoor's reputation, result in a potential loss of neighbors and engagement, and adversely affect Nextdoor's business, operating results, and financial condition.

Nextdoor's reputation and ability to attract, retain, and serve its neighbors and to scale its product offerings is dependent upon the reliable performance of its platform and its underlying technical infrastructure. Nextdoor has in the past experienced, and may in the future experience, interruptions in the availability or performance of its platform from time to time. Nextdoor's systems may not be adequately designed or may not operate with the reliability and redundancy necessary to avoid performance delays or outages that could be harmful to Nextdoor's business. If Nextdoor's platform is unavailable when neighbors attempt to access it, or if it does not load as quickly as expected, neighbors may not use Nextdoor's platform as often in the future, or at all, and Nextdoor's ability to serve advertisements may be disrupted, any of which could adversely affect Nextdoor's business, operating results, and financial condition. As the amount and types of information shared on Nextdoor continues to grow and evolve, as the usage patterns of Nextdoor's communities continues to evolve, and as Nextdoor's internal operational demands continue to grow, Nextdoor will need an increasing amount of technical infrastructure, including network capacity and computing power, to continue to satisfy its needs. If Nextdoor fails to continue to effectively scale and grow its technical infrastructure to accommodate these increased demands, neighbor engagement and revenue growth may be adversely impacted. Moreover, as Nextdoor scales its platform and product offerings, including video and other platform features, that may place strain on its technical infrastructure and Nextdoor may also be unsuccessful in scaling its technical infrastructure to accommodate new product offerings and increased platform usage cost-effectively. In addition, Nextdoor's business may be subject to interruptions, delays, or failures resulting from earthquakes, fires, floods, adverse weather conditions, other natural disasters, power loss, terrorism, pandemics, geopolitical conflict, other physical security threats, cyber-attacks, or other catastrophic events. If such an event were to occur, neighbors may be subject to service disruptions or outages and Nextdoor may not be able to recover its technical infrastructure and neighbor data in a timely manner to restart or provide its services, which may adversely affect Nextdoor's financial results. In addition, the substantial majority of Nextdoor's employees are based in its headquarters located in San Francisco, California. If there is a catastrophic failure involving Nextdoor's systems or major disruptive event affecting Nextdoor's headquarters or the San Francisco area in general, Nextdoor may be unable to operate its platform.

A substantial portion of Nextdoor's network infrastructure is provided by third parties, including Amazon Web Services. Any disruption or failure in the services Nextdoor receives from these providers could impact the availability of its platform and could adversely impact Nextdoor's business, operating results and financial condition. Any financial or other difficulties these providers face may adversely affect Nextdoor's business, and Nextdoor exercises little control over these providers, which increases Nextdoor's reliance on and vulnerability to problems with the services they provide.

Any of these developments may result in interruptions in the availability or performance of Nextdoor's platform, result in neighbors ceasing to use its platform, require unfavorable changes to its platform, delay the introduction of future products, or otherwise adversely affect Nextdoor's reputation, business, operating results, and financial condition.

Nextdoor has experienced rapid growth and expects to invest in its growth for the foreseeable future. If Nextdoor fails to manage its growth effectively, its business, operating results, and financial condition would be adversely affected.

Nextdoor has experienced rapid growth in recent periods and it expects to continue to invest broadly across its organization to support its growth. Nextdoor's revenue has grown from $82.6 million for the year ended December 31, 2019 to $123.3 million for the year ended December 31, 2020 and from $51.3 million for the six months ended June 30, 2020 to $80.2 million for the six months ended June 30, 2021. Weekly Active Users on Nextdoor's platform have grown from 15.5 million as of March 31, 2019 to 29.2 million as of June 30, 2021. Moreover, the number of Nextdoor's full-time employees has grown from 240 as of January 1, 2019 to 565 as of June 30, 2021. Although Nextdoor has experienced rapid growth historically, it may not sustain its current growth rates, nor can Nextdoor assure you that its investments to support its growth will be successful. The growth and expansion of

Nextdoor's business will require it to invest significant financial and operational resources and the continuous dedication of its management team.

Nextdoor plans to continue to expand its international operations into more countries in the future, which will place additional demands on its resources and operations. The growth and expansion of Nextdoor's business has placed, and continues to place, a significant strain on its management, operations, and financial and technical infrastructure. In the event of further growth of Nextdoor's business or in the number of Nextdoor's third-party relationships, its information technology systems or its internal controls and procedures may not be adequate to support Nextdoor's operations.

To manage any future growth effectively, Nextdoor must continue to improve and expand its information technology and financial infrastructure, its operating and administrative systems and controls, and its ability to manage headcount, capital, and processes in an efficient manner. Failure to manage growth effectively could result in increases in costs, difficulties in introducing new products and services or enhancing the platform, loss of neighbors and advertisers, or other operational difficulties, any of which could adversely affect Nextdoor's business, operating results, and financial condition. For example, as Nextdoor expands its product offerings, including video, it may not be able to do so cost-effectively. Effectively managing Nextdoor's growth may also be more difficult to accomplish the longer that Nextdoor's employees, its advertisers, neighbors and the overall economy is impacted due to the COVID-19 pandemic.

Nextdoor may not be able to successfully implement or scale improvements to its systems, processes, and controls in an efficient or timely manner. In addition, Nextdoor's existing systems, processes, and controls may not prevent or detect all errors, omissions, or fraud. Nextdoor may also experience difficulties in managing improvements to its systems, processes, and controls or in connection with third-party software licensed to help Nextdoor with such improvements. Any future growth will continue to add complexity to Nextdoor's organization and require effective coordination throughout its organization. Failure to manage any future growth effectively could result in increased costs, cause difficulty or delays in attracting new neighbors or retaining or increasing the engagement of existing neighbors, cause difficulties in introducing new features, impact Nextdoor's ability to attract and retain talent or cause other operational difficulties, and any of these difficulties would adversely impact Nextdoor's business, operating results, and financial condition.

If Nextdoor does not successfully anticipate market needs and develop products and services and platform enhancements that meet those needs, or if those products, services and platform enhancements do not gain market acceptance, its business, operating results, and financial condition will be adversely impacted.

Nextdoor may not be able to anticipate future market needs or be able to improve its platform or to develop new products and services or platform enhancements to meet such needs on a timely basis, if at all. In addition, Nextdoor's inability to diversify beyond its current offerings could adversely affect its business. Any new products or services or platform enhancements that Nextdoor introduces, including by way of acquisitions, may not achieve any significant degree of market acceptance from current or potential neighbors, which would adversely affect Nextdoor's business, operating results, and financial condition. In addition, the introduction of new products or services or platform enhancements may decrease neighbor engagement with Nextdoor's platform, thereby offsetting the benefit of even a successful product or service introduction, any of which could adversely impact Nextdoor's business, operating results, and financial condition.

If Nextdoor's efforts to build strong brand identity and reputation are not successful, it may not be able to attract or retain neighbors, and its business, operating results, and financial condition will be adversely affected.

Nextdoor believes that maintaining and enhancing the 'Nextdoor' brand and reputation is critical to retaining and growing neighbors and advertisers on its platform. Nextdoor anticipates that maintaining and enhancing its brand and reputation will depend largely on its continued ability to provide high-quality, relevant, reliable, trustworthy and innovative features on its platform, which may require substantial investment and may not be successful. Nextdoor may need to introduce new products, services and features or updates to its platform and features that require neighbors to agree to new terms of service that its neighbors do not like, which may negatively affect Nextdoor's brand and reputation.

Additionally, advertisements or actions of Nextdoor's advertisers may affect Nextdoor's brand and reputation if neighbors do not think the advertisements help them accomplish their objectives, view the advertisements as intrusive or misleading or have poor experiences with Nextdoor's advertisers.

Nextdoor's brand and reputation may also be negatively affected by the content or actions of neighbors that are deemed to be hostile or inappropriate to other neighbors, by the actions of neighbors acting under false or inauthentic identities, by the use of Nextdoor's platform to disseminate misleading or false information, the use of Nextdoor's platform for fraudulent schemes and scams, or by the use of Nextdoor's service for illicit, illegal or objectionable ends. Nextdoor also may fail to respond expeditiously to the sharing of illegal, illicit or objectionable content on its service or objectionable practices by advertisers, or to otherwise address its neighbors' concerns, which could erode confidence in Nextdoor's brand and damage its reputation. Nextdoor expects that its ability to identify and respond to this content in a timely manner may decrease as the number of neighbors grows, as the amount of content on the platform increases or as Nextdoor expands its product and service offerings on its platform. Any governmental or regulatory inquiry, investigation or action, including based on the appearance of illegal, illicit or objectionable content on Nextdoor's platform or the failure to comply with laws and regulations, could damage Nextdoor's brand and reputation, regardless of the outcome.

Nextdoor has experienced, and expects to continue to experience, media, legislative, governmental and regulatory scrutiny of its decisions. Any scrutiny regarding Nextdoor, including regarding its data privacy, content moderation or other practices, platform changes, platform quality, litigation or regulatory action, or regarding the actions of its employees, neighbors, or advertisers or other issues, may harm Nextdoor's brand and reputation. In addition, scrutiny of other companies in Nextdoor's industry, including such companies' data privacy, content moderation or other practices, could also have a negative impact on Nextdoor's brand and reputation. These concerns, whether actual or unfounded, may also deter neighbors or advertisers from using Nextdoor's platform. In addition, Nextdoor may fail to adequately address the needs of neighbors and advertisers which could erode confidence in Nextdoor's brand and damage its reputation. If Nextdoor fails to promote and maintain the 'Nextdoor' brand or preserve its reputation, or if Nextdoor incurs excessive expenses in this effort, its business, operating results, and financial condition could be adversely impacted.

Unfavorable media coverage negatively affects Nextdoor's business from time to time.

Unfavorable publicity regarding Nextdoor, for example regarding Nextdoor's privacy or cybersecurity practices, terms of service, advertising policies, platform changes, platform quality, litigation or regulatory activity, the actions of Nextdoor's advertisers, the use of Nextdoor's platform for illicit or objectionable ends, the substance or enforcement of Nextdoor's community standards, the actions of Nextdoor's neighbors, the quality and integrity of content shared Nextdoor's platform, or the actions of other companies that provide similar services to Nextdoor, has in the past, and could in the future, adversely affect Nextdoor's reputation. For example, Nextdoor has been, and may in the future be, subject to negative publicity in connection with its handling of misinformation and other illicit or objectionable use of its platform. Any such negative publicity could have an adverse effect on the size, engagement, and loyalty of Nextdoor's neighbor base and advertiser demand for advertising on Nextdoor's platform, which could result in decreased revenue and adversely affect Nextdoor's business, operating results, and financial condition, and Nextdoor has experienced such adverse effects to varying degrees from time to time.

Health epidemics, including the COVID-19 pandemic have had or could have an adverse impact on Nextdoor's business, operations and the markets and communities in which Nextdoor, its partners and its customers operate. In addition, during the COVD-19 pandemic, Nextdoor experienced an increase in neighbor growth and engagement and there is no guarantee that Nextdoor will be able to maintain its neighbor growth and engagement as the COVID-19 pandemic subsidies.

The global COVID-19 pandemic outbreak and the various attempts to contain it have created significant volatility, uncertainty and economic disruption. It has adversely affected the broader economies, financial markets, and overall demand for advertising.

As a result of the COVID-19 pandemic, Nextdoor temporarily closed all its offices (including its corporate headquarters) globally, incurred additional lease expenses for leases that could not be terminated and implemented

certain travel restrictions, all of which have disrupted and could continue to disrupt how Nextdoor operates its business, including limiting certain of Nextdoor's sales and marketing plans and requiring Nextdoor to manage a significant majority of its workforce remotely. Moreover, as a result of the COVID-19 pandemic, the ability and willingness of advertisers to spend on Nextdoor has fluctuated. For example, during the second quarter of 2020, advertisers reduced their advertising spend with Nextdoor as a result of the impact of the COVID-19 pandemic on global macroeconomic conditions and on the advertising industry in general. Nextdoor does not know how evolving events related to the COVID-19 pandemic will continue to affect neighbor and advertiser behavior in the future. Nextdoor may not be able to recognize revenue, collect payment or generate future revenue from advertisers, including from those that have been or may be forced to close their businesses or are otherwise impacted by an economic downturn as a result of the COVID-19 pandemic. The pandemic has, and could in the future, adversely affect Nextdoor's business, revenue growth rate, financial performance and stock price.

Further, during the COVID-19 pandemic and the related shelter-in-place order, Nextdoor saw an increase in neighbor growth and engagement on its platform. The post-pandemic period may present challenges such as neighbor growth and engagement declining or neighbor behavior changing unexpectedly and in ways that are difficult for Nextdoor to anticipate or measure, resulting in a decrease in engagement with or reduced or different usage of its platform. Nextdoor's neighbor and revenue growth rates may continue to be volatile in the near term as a result of the COVID-19 pandemic, although Nextdoor is unable to predict the duration or degree of such volatility with any certainty. As a result, Nextdoor's financial and operating measures may not be indicative of results for future periods.

Nextdoor is currently unable to accurately predict the full impact that the COVID-19 pandemic will have on its business, operating results, and financial condition due to numerous uncertainties, including the severity and transmission rate of the virus, duration of the pandemic, including any resurgences, the extent and effectiveness of containment actions and other public health measures, the development, distribution and public acceptance of vaccines and treatments, and the impact of these and other factors on its employees, neighbors, advertisers. The COVID-19 pandemic, as well as any subsequent recovery period, may also have the effect of heightening many of the other risks described in this 'Risk Factor' section.

Nextdoor plans to continue expanding its international operations where it has limited operating experience and may be subject to increased business, regulatory and economic risks that could seriously harm its business, operating results, and financial condition.

Nextdoor plans to continue expanding its business operations abroad by opening new and expanding within existing neighborhoods outside of the United States. As of June 30, 2021, the Nextdoor platform was accessible in 11 countries (including the United States) and had over 280,000 neighborhoods. Nextdoor plans to enter new international markets where it has limited or no experience in marketing, selling, advertising and deploying its platform and related advertising. Any of Nextdoor's limited experience and infrastructure in such markets, individuals' lack of familiarity with Nextdoor or its platform, the existence of alternative platforms in such jurisdictions that offer similar products and services or the lack of a critical mass of potential neighbors in such markets may make it more difficult for Nextdoor to effectively monetize any increase in neighbors in those markets, and may increase Nextdoor's costs without a corresponding increase in revenues. If Nextdoor fails to deploy or manage its operations in international markets successfully, comply with international regulations or effectively monetize its platform in international markets to the same degree as it is able to monetize its efforts within the United States, its business, operating results and financial conditions will be adversely affected. In the future, if Nextdoor's international operations increase, or more of its expenses are denominated in currencies other than the U.S. dollar, Nextdoor's operating results may be more greatly affected by fluctuations in the exchange rates of the currencies in which it does business. In addition, as Nextdoor's international operations and sales to advertisers continue to grow, it will be subject to a variety of risks inherent in doing business internationally, including:

•political, social and economic instability;

•risks related to the legal and regulatory environment in foreign jurisdictions, including with respect to privacy and data protection, and unexpected changes in laws, regulatory requirements, and enforcement;

•potential damage to Nextdoor's brand and reputation due to compliance with local laws, including potential censorship and requirements to provide neighbor information to local authorities;

•enhanced difficulty in reviewing content on the Nextdoor platform and enforcing community standards across different languages and countries;

•fluctuations in currency exchange rates;

•foreign exchange controls and tax and other regulations and orders that might prevent Nextdoor from repatriating cash earned in countries outside the United States or otherwise limit Nextdoor's ability to move cash freely, and impede its ability to invest such cash efficiently;

•compliance with multiple U.S. and international tax jurisdictions and management of tax impact of global operations;

•potentially higher levels of credit risk and payment fraud;

•difficulties integrating any foreign acquisitions;

•burdens of complying with a variety of foreign laws, including laws related to taxation, content removal, data localization, payments, and regulatory oversight;

•reduced protection for intellectual property rights in some countries;

•different regulations and practices with respect to employee/employer relationships, existence of workers' councils and labor unions, increase in labor costs due to high wage inflation in certain international jurisdictions, and other challenges caused by distance, language and cultural differences, making it harder to do business in certain international jurisdictions; and

•difficulties in staffing and managing global operations and the increased travel, infrastructure, and legal compliance costs associated with multiple international locations.

In addition, Nextdoor must manage the potential conflicts between locally accepted business practices in any given jurisdiction and its obligations to comply with laws and regulations, including anti-money laundering laws, anti-corruption laws or regulations applicable to Nextdoor, such as the U.S. Foreign Corrupt Practices Act ('FCPA'), and the U.K. Bribery Act 2010 ('Bribery Act'). Nextdoor also must manage its obligations to comply with laws and regulations related to export controls, sanctions, and embargoes, including regulations established by the U.S. Office of Foreign Assets Control. Government agencies and authorities have a broad range of civil and criminal penalties they may seek to impose against companies for violations of anti-corruption laws or regulations, export controls, and other laws, rules, sanctions, embargoes, and regulations. Any failure by Nextdoor to comply with local business practices or the laws and regulations applicable to Nextdoor in the markets it operates may adversely affect Nextdoor's business, operating results, and financial condition. Additionally, if Nextdoor is unable to expand internationally and manage the complexity of its global operations successfully, Nextdoor's business, operating results, and financial condition could be adversely affected.

If Nextdoor needs additional capital in the future, it may not be available on favorable terms, if at all.

Nextdoor has historically relied on outside financing to fund its operations, capital expenditures and expansion. Nextdoor may require additional capital from equity or debt financing in the future to support its growth, fund its operations or to respond to competitive pressures or strategic opportunities. Nextdoor may not be able to secure timely additional financing on favorable terms, if at all. If Nextdoor raises additional funds through further issuances of equity, convertible debt securities or other securities convertible into equity, its existing stockholders, including you, could suffer significant dilution in their percentage ownership of Nextdoor, and any new securities that Nextdoor issues could have rights, preferences and privileges senior to those of holders of its common stock. Any debt financing that Nextdoor secures in the future could involve restrictive covenants relating to its capital raising activities and other financial and operational matters, including the ability to pay dividends. This may make it more difficult for Nextdoor to obtain additional capital and to pursue business opportunities, including potential

acquisitions. If Nextdoor is unable to obtain adequate financing or financing on terms that are satisfactory to it, if and when Nextdoor requires financing, Nextdoor's ability to grow or support its business and to respond to business challenges that it may face could be significantly limited.

Nextdoor plans to continue to make acquisitions, which could harm its financial condition or results of operations and may adversely affect the price of its Class A common stock.

As part of its business strategy, Nextdoor has made, and intends to make acquisitions to add specialized employees and complementary companies, products or technologies, and enter new geographic regions. Nextdoor's previous and future acquisitions may not achieve Nextdoor's goals, and it may not realize benefits from acquisitions it makes in the future. If Nextdoor fails to successfully integrate acquisitions, or the personnel or technologies associated with those acquisitions, the business, operating results, and financial condition of Nextdoor could be harmed. Any integration process will require significant time and resources, and Nextdoor may not be able to manage the process successfully. Nextdoor's acquisition strategy may change over time and any future acquisitions it completes could be viewed negatively by neighbors, advertisers, investors or other parties with whom it does business. Nextdoor may not successfully evaluate or utilize the acquired technology and accurately forecast the financial impact of an acquisition, including accounting charges. Nextdoor may also incur unanticipated liabilities that it assumes as a result of acquiring companies. Nextdoor may have to pay cash, incur debt or issue equity securities to pay for any such acquisition, each of which could affect its financial condition or the value of its securities. In the future, Nextdoor may not be able to find other suitable acquisition candidates, and it may not be able to complete acquisitions on favorable terms, if at all. Nextdoor's acquisition strategy could require significant management attention, disrupt its business and harm its business, operating results, and financial condition.

Nextdoor's business depends largely on its ability to attract and retain talented employees, including senior management. If Nextdoor loses the services of Sarah Friar, its Chief Executive Officer and President, or other members of its senior management team, Nextdoor may not be able to execute on its business strategy.

Nextdoor's future success depends on its continuing ability to attract, train, assimilate, and retain highly skilled personnel, including software engineers and sales personnel. Nextdoor faces intense competition for qualified individuals from numerous software and other technology companies. In addition, competition for qualified personnel, particularly software engineers, is particularly intense in the San Francisco Bay Area, where Nextdoor's headquarters are located. Nextdoor may not be able to retain its current key employees or attract, train, assimilate, or retain other highly skilled personnel in the future. Nextdoor may incur significant costs to attract and retain highly skilled personnel, and it may lose new employees to its competitors or other technology companies before Nextdoor realizes the benefit of its investment in recruiting and training them. As Nextdoor moves into new geographies, it will need to attract and recruit skilled personnel in those areas. If Nextdoor is unable to attract and retain suitably qualified individuals who are capable of meeting its growing technical, operational, and managerial requirements, on a timely basis or at all, Nextdoor's business, operating results, and financial condition may be adversely affected.

Nextdoor's future success also depends in large part on the continued services of senior management and other key personnel. In particular, Nextdoor is dependent on the services of Sarah Friar, its Chief Executive Officer and President, who is critical to the future vision and strategic direction of Nextdoor's business. Nextdoor relies on its leadership team and key employees in the areas of engineering, sales and product development, design, marketing, operations, strategy, security, and general and administrative functions. Nextdoor's senior management and other key personnel are all employed on an at-will basis, which means that they could terminate their employment with Nextdoor at any time, for any reason, and without notice. Nextdoor does not currently maintain key-person life insurance policies on any of its officers or employees. If Nextdoor loses the services of senior management or other key personnel, or if it is unable to attract, train, assimilate, and retain the highly skilled personnel that it needs, Nextdoor's business, operating results, and financial condition could be adversely affected.

Volatility or lack of appreciation in Nextdoor's stock price may also affect its ability to attract and retain its key employees. Employees may be more likely to leave Nextdoor if the shares they own or the shares underlying their vested options have significantly appreciated in value relative to the original purchase price of the shares or the exercise price of the options, or conversely, if the exercise price of the options that they hold are significantly above the market price of Nextdoor's Class A common stock. If Nextdoor is unable to retain its employees, or if Nextdoor

needs to increase its compensation expenses to retain its employees, Nextdoor's business, operating results, and financial condition could be adversely affected.

Nextdoor's core values may conflict with the short-term interests of its business.

Nextdoor considers its core values as a guide to the decisions it makes, which Nextdoor believes is essential to its success in increasing its neighbor growth rate and engagement and in serving the best, long-term interests of Nextdoor and its stockholders. In the past, Nextdoor has forgone, and may in the future forgo, certain expansion or revenue opportunities that it does not believe are aligned with its core values, even if Nextdoor's decision may negatively impact its operating results in the short term. Nextdoor's decisions may not result in the long-term benefits that it expects, in which case its neighbor engagement, business, operating results, and financial condition could be harmed.

Nextdoor is dependent on third-party software and service providers, including the Google Ad Manager ('GAM') platform, for management and delivery of advertisements on the Nextdoor platform. Any failure or interruption experienced by such third-parties, including as a result of the COVID-19 pandemic, could result in the inability of certain businesses to advertise on Nextdoor's platform, and adversely impact Nextdoor's business, operating results, and financial condition.

Currently, Nextdoor is dependent on third-party software and service providers, including the GAM platform, for management and delivery of advertisements on the Nextdoor platform. As such, the continued use of third-party software and service providers, including GAM, is critical to Nextdoor's continued success and any service disruptions, adverse changes to the terms of use, pricing or related terms and conditions for such third-party providers' products, or difficulties with such products, including its data usage, meeting Nextdoor's requirements or standards could result in the inability of certain businesses to advertise on Nextdoor's platform, and adversely impact Nextdoor's business, operating results, and financial condition.

Nextdoor relies on third-party software and service providers, including Amazon Web Services ('AWS'), to provide systems, storage and services for its platform. Any failure or interruption experienced by such third parties, including as a result of the COVID-19 pandemic, could result in the inability of neighbors and advertisers to access or utilize Nextdoor's platform, and adversely impact Nextdoor's business, operating results, and financial condition.

Nextdoor relies on third-party software and service providers, including AWS, to provide systems, storage and services, including neighbor login authentication, for its website. Any technical problem with, cyber-attack on or loss of access to such third parties' systems, servers, or technologies could result in the inability of neighbors to access the Nextdoor platform or result in the theft of neighbors' personal information.

Any significant disruption, limitation or loss of Nextdoor's access to or other interference with its use of AWS, including as a result of termination by AWS of its agreement with Nextdoor, would negatively impact Nextdoor's business, operating results, and financial condition. In addition, any transition of the cloud services currently provided by AWS to another cloud services provider would be difficult to implement and would cause Nextdoor to incur significant time and expense and could disrupt or degrade Nextdoor's ability to deliver its products and services. The level of service provided by AWS could affect the availability or speed of Nextdoor's services. If neighbors or advertisers are not able to access Nextdoor's platform or encounter difficulties in doing so, Nextdoor may lose neighbors or advertisers, which could harm its reputation, business, operating results, and financial condition.

Nextdoor utilizes data center hosting facilities operated by AWS, located in various facilities. Nextdoor is unable to serve network traffic from back-up data center services. An unexpected disruption of services provided by these data centers could hamper Nextdoor's ability to handle existing or increased traffic, result in the loss of data or cause Nextdoor's platform to become unavailable, which may harm Nextdoor's reputation, business, operating results, and financial condition.

Nextdoor relies on third parties, including email providers, mobile data networks, geolocation providers and the United States Postal Service ('USPS') to verify its neighbors' addresses. Any failure or interruption experienced by such third parties, including the USPS, could result in the inability of neighbors to join Nextdoor's platform, resulting in harm to Nextdoor's reputation and an adverse impact to its business, operating results, and financial condition.

Nextdoor relies on third parties to verify its neighbors' addresses through several methods, including but not limited to email, SMS text message, phone calls, geolocation and mailed invitations. For example, Nextdoor utilizes email providers, mobile data networks, geolocation providers and the USPS to verify neighbors' addresses. Address verification is a critical feature of Nextdoor's platform because it demonstrates that neighbors actually live in the neighborhood they desire to join. Any failure, interruption, or loss of access to such third parties or their software or the USPS could result in the inability of neighbors to join Nextdoor's platform. Nextdoor's reliance on third parties makes it vulnerable to any service interruptions, whether as a result of a cyber-attack, security breach, weather or other events, or delays in their operations. Additionally, alternative email providers, mobile data networks, geolocation providers or postal providers may be more costly to use than Nextdoor's current providers, including the USPS. Any disruption in the third parties, including the USPS, could harm its neighbor growth, which in turn could make Nextdoor a less attractive advertising platform and harm its reputation, and to its business, operating results, and financial condition.

Technologies have been developed that can block the display of advertisements on the Nextdoor platform, which could adversely impact its business, operating results, and financial condition.

Technologies have been developed, and will likely continue to be developed, that can block the display of advertisements on the Nextdoor platform. Nextdoor generates substantially all of its revenue from advertising, and ad-blocking technologies may prevent the display of certain advertisements appearing on Nextdoor's platform, which could harm its business, operating results, and financial condition. Existing ad-blocking technologies that have not been effective on Nextdoor's platform may become effective as Nextdoor makes certain platform changes, and new ad-blocking technologies are developed in the future. More neighbors may choose to use such ad-blocking products to block or obscure the display of advertisements on Nextdoor's platform if Nextdoor is unable to successfully balance the amount of its organic content and paid advertisements, or if neighbors' attitudes toward advertisements become more negative. Further, regardless of their effectiveness, ad-blockers may generate concern regarding the health of the digital advertising industry, which could reduce the value of digital advertising and harm Nextdoor's business, operating results, and financial condition.

Security breaches, including improper access to or disclosure of Nextdoor's data or its neighbors' data, or other hacking and phishing attacks on Nextdoor's or third-party systems, could harm its reputation and adversely affect its business.

Nextdoor collects, stores, and otherwise processes personal data relating to a number of individuals such as its neighbors, employees and partners, including, but not limited to, neighbor contact details, network details, and location data. The evolution of technology systems introduces unknown and complex security risks that can be unpredictable and difficult to defend against. Cyber-attacks continue to evolve in sophistication and volume, and inherently may be difficult to detect for long periods of time. In particular, social media companies, like Nextdoor, are prone to cyber-attacks by third parties seeking unauthorized access to company or user data or to disrupt their ability to provide access to their products and services.

Nextdoor takes a variety of technical and organizational security measures and other measures to protect its data. Although Nextdoor has implemented systems and processes that are designed to protect its data and its neighbors' data, prevent data loss, disable undesirable accounts and activities on its platform and prevent or detect security breaches, and maintains an information security policy, such measures cannot provide absolute security, and despite measures that Nextdoor has or will in the future put in place, Nextdoor may be unable to anticipate or prevent unauthorized access to such data. For example, computer malware, viruses, social engineering (predominantly spear phishing attacks), and general hacking have become more prevalent in the industry, have occurred on Nextdoor's systems in the past, and are likely to occur on Nextdoor's systems in the future. In addition, Nextdoor regularly encounters attempts to create false or undesirable accounts or take other actions on its platform

for purposes such as spamming, spreading misinformation, or other objectionable ends. Nextdoor's efforts to protect its company data or the information that it receives may also be unsuccessful due to software bugs or other technical malfunctions; employee, contractor, or vendor error or malfeasance; government surveillance; or other threats that evolve.

Some third parties, including advertisers and vendors, may store information that Nextdoor shares with them on their networks. If these third parties fail to implement adequate data-security practices or fail to comply with their contractual obligations and/or, where applicable, Nextdoor's terms and policies, neighbor data may be improperly accessed, used or disclosed. Even if these third parties take all the necessary precautions and comply with their applicable obligations, their networks may still suffer a breach, which could compromise neighbor data.

Security breaches may cause interruptions to Nextdoor's platform, degrade the neighbor experience, cause neighbors or advertisers to lose confidence and trust in Nextdoor's platform, impair Nextdoor's internal systems, or result in financial harm to Nextdoor.

In addition, affected neighbors, government authorities or other third parties could initiate legal or regulatory actions against Nextdoor in connection with any actual or perceived security breaches or improper disclosure of data, which could cause Nextdoor to incur significant expense and liability that may not be fully covered by insurance, if at all, or result in orders or consent decrees forcing Nextdoor to modify its business practices. Such incidents or Nextdoor's efforts to remediate such incidents may also result in a decline in its active neighbor base or engagement levels and trust. In addition, such incidents could also result in the loss or misuse of such data, which could harm Nextdoor's business and reputation and diminish its competitive position. In addition, any of these events could have a material and adverse effect on Nextdoor's business, operating results, financial condition, market acceptance of Nextdoor's products or revenues and may also divert development resources and increase service and support costs.

Distribution and marketing of, and access to, Nextdoor's platform depends, in significant part, on a variety of third-party publishers and platforms (including mobile app stores, third-party payment providers, computer systems, and other communication systems and service providers). If these third parties limit, prohibit or otherwise interfere with or change the terms of the distribution, use or marketing of Nextdoor's platform in any material way, it could materially adversely affect Nextdoor's business, operating results, and financial condition.

Nextdoor markets and distributes its platform (including related mobile applications) through a variety of third-party publishers and distribution channels. Nextdoor's ability to market its brands on any given property or channel is subject to the policies of the relevant third party. There is no guarantee that mobile platforms will continue to feature Nextdoor, or that neighbors using mobile devices will continue to use Nextdoor's platform rather than competing products. Nextdoor is dependent on the interoperability of its platform with mobile operating systems, networks, technologies, products, and standards that Nextdoor does not control, such as the Android and iOS operating systems. Any changes, bugs, or technical issues in such systems, or changes in Nextdoor's relationships with mobile operating system partners, handset manufacturers, or mobile carriers, or in their terms of service or policies that degrade the functionality of Nextdoor's platform, reduce or eliminate Nextdoor's ability to update or distribute its platform, give preferential treatment to competitive products, limit Nextdoor's ability to deliver, target, or measure the effectiveness of advertisements, or charge fees related to the distribution of Nextdoor's platform or Nextdoor's delivery of advertisements could materially adversely affect the usage of Nextdoor's platform on mobile devices. For example, the release of iOS 14.5 brought with it a number of new changes, including the need for neighbors using the app to opt in before their identifier for advertisers ('IDFA') can be accessed by an app (which came into effect in April 2021). Apple's IDFA is a string of numbers and letters assigned to Apple devices which advertisers use to identify app users to deliver personalized and targeted advertising. As a consequence, the ability of advertisers to accurately target and measure their advertising campaigns at the neighbor level will depend on the opt-in rate to grant IDFA access and if the opt-in rate is low, advertisers' ability to target and measure advertising campaigns on Nextdoor may become significantly limited. Nextdoor did not observe any negative impact on its business, operating results or financial condition, including its revenue, revenue growth rates, and operating income (loss), related to the introduction of IDFA during the three months ended June 30, 2021, though Nextdoor may be impacted by such changes, or other changes to third-party policies or applications in the future, and as a result, its business, operating results and financial condition, including its revenue, revenue growth rates, and operating

income (loss), could, in the future, be adversely impacted by any such changes. Further, Apple announced changes to be introduced for the Apple mail client available on its operating systems, including iOS 15, iPadOS 15, and macOS 12, expected to be released in September 2021, which will impact Nextdoor's ability to measure the effectiveness of its advertisements. As a result, advertisers may find Nextdoor's products less appealing and may seek alternative platforms on which to run their advertising campaigns.

Further, certain publishers and channels have, from time to time, limited or prohibited advertisements for a variety of reasons. There is no assurance that Nextdoor will not be limited or prohibited from using certain current or prospective marketing channels in the future. If this were to happen in the case of a significant marketing channel and/or for a significant period of time, Nextdoor's business, operating results, and financial condition could be materially adversely affected.

Nextdoor's platform and internal systems rely on software and hardware that is highly technical, and any errors, bugs, or vulnerabilities in these systems, or failures to address or mitigate technical limitations in Nextdoor's systems, could adversely affect its business.

Nextdoor's platform and internal systems rely on software and hardware, including software and hardware developed or maintained internally and/or by third parties, that is highly technical and complex. In addition, Nextdoor's platform and internal systems depend on the ability of such software and hardware to store, retrieve, process, and manage immense amounts of data. The software and hardware on which Nextdoor relies has contained, and will in the future contain, errors, bugs, or vulnerabilities, and Nextdoor's systems are subject to certain technical limitations that may compromise Nextdoor's ability to meet its objectives. Some errors, bugs, or vulnerabilities inherently may be difficult to detect and may only be discovered after the code has been released for external or internal use. Errors, bugs, vulnerabilities, design defects, or technical limitations within the software and hardware on which Nextdoor relies have in the past led to, and may in the future lead to, outcomes including a negative experience for neighbors and advertisers who use Nextdoor's platform, compromised ability of Nextdoor's platform to perform in a manner consistent with Nextdoor's terms, contracts, or policies, delayed product introductions or enhancements, targeting, measurement, or billing errors, compromised ability to protect the data of neighbors and/or Nextdoor's intellectual property or other data, or reductions in Nextdoor's ability to provide some or all of its services. For example, Nextdoor makes commitments to its neighbors as to how their data will be used within and across its platform, and Nextdoor's systems are subject to errors, bugs and technical limitations that may prevent it from fulfilling these commitments reliably. In addition, any errors, bugs, vulnerabilities, or defects in Nextdoor's systems or the software and hardware on which the company relies, failures to properly address or mitigate the technical limitations in its systems, or associated degradations or interruptions of service or failures to fulfill Nextdoor's commitments to its neighbors, have in the past led to, and may in the future lead to, outcomes including damage to Nextdoor's reputation, loss of neighbors, loss of advertisers, loss of revenue, regulatory inquiries, litigation, or liability for fines, damages, or other remedies, any of which could adversely affect Nextdoor's business, operating results, and financial condition.

Risks related to financial and accounting matters

Nextdoor's operating results may fluctuate significantly, which makes its future results difficult to predict.

Nextdoor's quarterly and annual operating results have fluctuated in the past and may fluctuate in the future. Additionally, Nextdoor has a limited operating history with the current scale of its business, which makes it difficult to forecast its future results and subjects Nextdoor to a number of uncertainties, including Nextdoor's ability to plan for and anticipate future growth. As a result, you should not rely upon Nextdoor's past quarterly and annual operating results as indicators of future performance. Nextdoor has encountered, and will continue to encounter, risks and uncertainties frequently experienced by growing companies in rapidly evolving markets, such as the risks and uncertainties described herein. Nextdoor's operating results in any given quarter can be influenced by numerous factors, many of which are unpredictable or are outside of Nextdoor's control, including, but not limited to:

•Nextdoor's ability to generate revenues from its platform;

•Nextdoor's ability to acquire, retain, and grow its neighbors and neighbor engagement on its platform;

•ability to attract and retain advertisers;

•ability to recognize revenue or collect payments from advertisers in a particular period;

•fluctuations in spending by Nextdoor's advertisers due to seasonality, episodic regional or global events, including the COVID-19 pandemic, or other factors;

•fluctuations in internet usage generally;

•the number, prominence, size, format, quality and relevancy of advertisements shown to neighbors;

•the success of technologies designed to block the display of advertisements;

•the pricing of Nextdoor's advertisements;

•the timing, cost of and mix of new and existing sales and marketing and promotional efforts;

•the availability of Nextdoor's platform and app on mobile devices and other third-party platforms;

•changes to Nextdoor's platform or the development and introduction of new products or services by Nextdoor's competitors;

•changes in advertising industry association rules and standards that limit Nextdoor's ability to deliver, target or measure the effectiveness of advertising, such as the Network Advertising Initiative ('NAI'), and Interactive Advertising Bureau ('IAB');

•neighbor behavior or platform changes that may reduce traffic to features of the platform that Nextdoor monetizes;

•system failures, disruptions, breaches of security or privacy, whether on Nextdoor's platform or on those of third parties, and the costs associated with any such breaches and remediation;

•negative publicity associated with Nextdoor's platform, including as a result of content on its platform, security breaches and neighbor privacy concerns that may result in advertisers reducing or eliminating their spend with Nextdoor;

•health epidemics, such as the COVID-19 pandemic, influenza, and other highly communicable diseases or viruses;

•the timing of incurring additional expenses, such as increases in sales and marketing or research and development, including as a result of the COVID-19 pandemic;

•adverse litigation judgments, settlements, or other litigation-related costs;

•changes in the legislative or regulatory environment, including with respect to privacy and cybersecurity, or actions by governments or regulators, including fines, orders, or consent decrees;

•changes in U.S. generally accepted accounting principles; and

•changes in domestic and global business and macroeconomic conditions, including as a result of the COVID-19 pandemic.

The impact of one or more of the foregoing and other factors may cause Nextdoor's operating results to vary significantly. As such, quarter-to-quarter comparisons of Nextdoor's operating results may not be meaningful and should not be relied upon as an indication of future performance. If Nextdoor's quarterly and annual operating

results fall below the expectations of investors or securities analysts, the price of its Class A common stock could decline substantially. If Nextdoor fails to meet or exceed the expectations of investors or securities analysts, then the trading price of its Class A common stock could fall substantially, and Nextdoor could face costly lawsuits, including securities class action suits. Furthermore, any quarterly or annual fluctuations in Nextdoor's operating results may, in turn, cause the price of its stock to fluctuate substantially.

In addition, Nextdoor believes that its rapid growth may understate the potential seasonality of its business. As Nextdoor's revenue growth rate slows, Nextdoor expects that the seasonality in its business may become more pronounced and may in the future cause its operating results to fluctuate. For example, advertising spending is traditionally seasonally strong in the fourth quarter of each year and Nextdoor believes that this seasonality affects its quarterly results, which generally reflect higher sequential revenue growth from the third to fourth quarter compared to sequential revenue growth from the fourth quarter to the subsequent first quarter. In addition, global economic concerns continue to create uncertainty and unpredictability and add risk to Nextdoor's future outlook. An economic downturn in any particular region in which Nextdoor does business or globally could result in reductions in revenue, as Nextdoor's advertisers reduce their advertising budgets, and other adverse effects that could harm Nextdoor's business, operating results, and financial condition.

Certain of Nextdoor's market opportunity estimates, growth forecasts and key metrics could prove to be inaccurate, which may increase the risk of Nextdoor becoming subject to legal proceedings, and any real or perceived inaccuracies may harm its reputation and negatively affect its business.

Market opportunity estimates and growth forecasts discussed herein, including those Nextdoor has generated itself, are subject to significant uncertainty and are based on assumptions and estimates that may not prove to be accurate. The key assumptions underlying Nextdoor's growth forecasts and projections include Nextdoor's ability to scale new neighbor growth, Nextdoor's ability to grow engagement by its existing neighbor base and Nextdoor's ability to increase monetization of its platform. These assumptions involve risks and uncertainties, including, but not limited to, those described in this 'Risk Factors' section, which could cause actual results to differ materially from Nextdoor's growth forecasts and projections. Unfavorable changes in any of these or other assumptions, most of which are beyond Nextdoor's control, could materially and adversely affect its business, operating results, and financial condition and result in the growth forecasts and projections being materially different than actual results. Market opportunity estimates and growth forecasts, whether obtained from third-party sources or developed internally, are subject to significant uncertainty and are based on assumptions and estimates that may not prove to be accurate. In particular, Nextdoor's estimates regarding its market penetration in new and existing markets are difficult to predict. In addition, this proxy statement/prospectus contains third-party estimates with respect to the addressable market for the global and U.S. digital advertising markets and the anticipated growth of such markets. Nextdoor cannot predict with precision its ability to address these markets. The addressable market Nextdoor estimates may not materialize for many years, if ever, and even if the markets in which it competes meet the size estimates and growth forecasted, its business could fail to grow at similar rates, if at all. Accordingly, Nextdoor's forecasts of market growth should not be taken as indicative of its future growth. In addition, members of the staff of the SEC have recently questioned whether the Private Securities Litigation Reform Act of 1995 safe harbor for forward-looking statements is applicable to SPAC transactions and the U.S. House Committee on Financial Services released draft legislation amending the Securities Act and the Exchange Act to specifically exclude SPACs from the safe harbor for forward-looking statements. If the safe harbor did not apply to such statements, Nextdoor may have increased risk of being subject to legal proceedings if the forward-looking statements were materially different than actual results.

Nextdoor regularly reviews key business metrics, including WAUs, Verified Users and ARPUs and other measures to evaluate growth trends, measure its performance, and make strategic decisions. These key metrics are calculated using internal company data derived from Nextdoor's analytics platform and have not been validated by an independent third party and there are inherent challenges in such measurements. For example, Apple announced changes to be introduced to the Apple email client available on its operating systems, including iOS 15, iPadOS 15, and macOS 12, expected to be released in September 2021, which will limit Nextdoor's ability to measure user engagement with Nextdoor's emails containing monetizable content for users that use the Apple email client. Nextdoor expects these changes to affect its ability to calculate WAUs, a key business metric. Following the introduction of these changes, Nextdoor will be required to rely on estimates based on past user behavior and

behavior of users engaging with Nextdoor's monetizable content on email clients other than the Apple email client in order to determine the portion of its WAU figure relating to users that engage solely with emails with monetizable content, which may impact the effectiveness of Nextdoor's analytics platform, as well as the accuracy of Nextdoor's WAU calculations. If Nextdoor fails to maintain an effective analytics platform, its key metrics calculations may be inaccurate, and Nextdoor may not be able to identify those inaccuracies. Nextdoor's key business metrics may also be impacted by compliance or fraud-related bans, technical incidents, or false or spam accounts in existence on its platform. Nextdoor regularly deactivates accounts that violate Nextdoor's terms of service, and exclude these accounts from the calculation of Nextdoor's key business metrics; however, Nextdoor may not succeed in identifying and removing all such accounts from its platform. If Nextdoor's metrics are incorrect or provide incomplete information about neighbors and their behavior, Nextdoor may make inaccurate conclusions about its business.

Nextdoor regularly reviews and may adjust its processes for calculating its market opportunity estimates, growth forecasts, and key metrics to improve their accuracy. Nextdoor's market opportunity estimates, growth forecasts, and key metrics may differ from estimates published by third parties or from similarly titled metrics of its competitors due to differences in methodology. If investors or analysts do not perceive Nextdoor's market opportunity estimates, growth forecasts, and key metrics to be accurate representations of its business, or if Nextdoor discovers material inaccuracies in its market opportunity estimates, growth forecasts and key metrics, Nextdoor's reputation, business, operating results, and financial condition would be adversely affected.

Nextdoor has a history of net losses and may experience net losses in the future and Nextdoor cannot assure you that it will achieve or sustain profitability. If Nextdoor cannot achieve and sustain profitability, its business, financial condition, and operating results will be adversely affected.

Nextdoor has experienced significant net losses each year since it began operations in 2007, including net losses of approximately $(73.3) million, $(75.2) million, and $(46.6) million for the years ended December 31, 2019 and 2020 and for the six months ended June 30, 2021, respectively. Nextdoor has an accumulated deficit of $431.7 million as of June 30, 2021. Nextdoor anticipates that its operating expenses and capital expenditures will increase substantially in the foreseeable future as it continues to invest in acquiring additional neighbors, increasing engagement on its platform, increasing monetization on its platform, expanding its platform and operations internationally, hiring additional team members, developing and enhancing its platform, marketing and sales, and enhancing its infrastructure. Nextdoor's expansion efforts may prove more expensive than it anticipates, and it may not succeed in increasing its revenues sufficiently to offset these higher expenses. Given the significant operating and capital expenditures associated with Nextdoor's business plan, Nextdoor expects to continue to incur net losses for the foreseeable future and cannot assure you that it will be able to achieve profitability. If Nextdoor does achieve profitability, it cannot be certain that Nextdoor will be able to sustain or increase such profitability.

Nextdoor's ability to use its U.S. federal and state net operating losses to offset future taxable income may be subject to certain limitations which could subject Nextdoor's business to higher tax liability.

As of December 31, 2020, Nextdoor had gross U.S. federal net operating loss ('NOL') carryforwards of approximately $331.9 million and gross state NOL carryforwards of approximately $185.0 million, which if not utilized, will begin to expire for federal and state income tax purposes beginning in 2028. To the extent that Nextdoor continues to generate taxable losses, unused losses will carry forward to offset future taxable income, if any. Under the 2017 Tax Cuts and Jobs Act (the 'Tax Act'), as modified by the Coronavirus Aid, Relief, and Economic Security Act ('CARES Act'), unused U.S. federal NOLs generated in tax years beginning after December 31, 2017, will not expire and may be carried forward indefinitely, but the deductibility of such federal NOLs in taxable years beginning after December 31, 2020, is limited to 80% of current year taxable income.

Under Section 382 of the Internal Revenue Code of 1986, as amended (the 'Code'), and corresponding provisions of state law, if a corporation that undergoes an 'ownership change,' which is generally defined as a greater than 50 percentage point change (by value) in its equity ownership by certain stockholders over a three-year period, the corporation's ability to utilize its pre-change NOL carryforwards to offset its post-change income or taxes may be limited. Nextdoor has not completed a Section 382 study, and it is possible that Nextdoor has previously undergone one or more ownership changes so that its use of NOLs is currently subject to limitation.

Nextdoor may experience an ownership change in connection with the Business Combination and may also experience ownership change(s) in the future as a result of subsequent shifts in its stock ownership, some of which may be outside Nextdoor's control. Therefore, it is possible that such an ownership change could limit the amount of NOLs Nextdoor can use to offset future taxable income. Nextdoor's current NOL carryforwards, and any NOL carryforwards of companies it has acquired, may be subject to limitations, thereby increasing Nextdoor's overall tax liability. Nextdoor's NOL carryforwards may also be impaired under similar provisions of state law. Nextdoor has recorded a full valuation allowance related to its U.S. federal and state NOL carryforwards and other net deferred tax assets due to the uncertainty of the ultimate realization of the future benefits of those assets. Nextdoor's NOL carryforwards may expire unutilized or underutilized, which could prevent it from offsetting future taxable income. Any future changes in U.S. tax laws in respect of the utilization of NOL carryforwards may further affect the limitation in future years. In addition, there may be periods during which the use of NOL carryforwards is suspended or otherwise limited at the state level, which could also impact Nextdoor's ability to utilize NOL carryforwards. As a result, even if Nextdoor attains profitability, it may be unable to use all or a material portion of its NOLs, which could adversely affect its business, operating results, financial condition, and cash flows.

Nextdoor's financial results may be adversely affected by changes in accounting principles generally accepted in the United States and its financial estimates may be different from its financial results.

GAAP is subject to interpretation by the Financial Accounting Standards Board, the American Institute of Certified Public Accountants, the SEC and various bodies formed to promulgate and interpret appropriate accounting principles. A change in these principles or interpretations could harm Nextdoor's revenue and financial results, and could affect the reporting of transactions completed before the announcement of a change.

If currency exchange rates fluctuate substantially in the future, Nextdoor's operating results, which are reported in U.S. dollars, could be adversely affected.

As Nextdoor continues to expand its international operations, it will become more exposed to the effects of fluctuations in currency exchange rates. A substantial majority of Nextdoor's revenues to date have been denominated in U.S. dollars and, therefore, Nextdoor has not historically been subject to foreign currency risk. In addition, as Nextdoor continues to expand internationally, it expects to incur increased expenses for employee compensation and other operating expenses at non-U.S. locations in the local currency. Fluctuations in the exchange rates between the U.S. dollar and other currencies could result in the dollar equivalent of such expenses being higher. This could have a negative impact on Nextdoor's operating results. Although Nextdoor may in the future decide to undertake foreign exchange hedging transactions to cover a portion of Nextdoor's foreign currency exchange exposure, it currently does not hedge its exposure to foreign currency exchange risks.

Nextdoor's global operations subject Nextdoor to potentially adverse tax consequences.

Nextdoor operates in a number of tax jurisdictions globally, including in the U.S. at the federal, state and local levels, and in many foreign countries, and plans to continue to expand the scale of its operations in the future. Nextdoor is subject to review and potential audit by a number of U.S. and non-U.S. tax authorities. A change in law or in Nextdoor's global operations could result in higher effective tax rates, reduced cash flows and lower overall profitability. In particular, Nextdoor's intercompany relationships are subject to complex transfer pricing regulations administered by taxing authorities in various jurisdictions. Significant judgment is required in determining Nextdoor's worldwide provision for income taxes and other tax liabilities. Tax authorities may disagree with and may challenge Nextdoor's tax positions. If Nextdoor's tax positions were not sustained, Nextdoor could be required to pay additional taxes, interest, penalties or other costs, or have other material consequences, which could result in higher effective tax rates, reduced cash flows, and lower overall profitability.

Taxing authorities in the U.S. and in foreign jurisdictions may successfully assert that Nextdoor should have collected or in the future should collect sales and use, gross receipts, value-added or similar taxes, and may successfully impose additional obligations on Nextdoor, and any such assessments or obligations could adversely affect Nextdoor's business, operating results, and financial condition.

The application of indirect taxes, such as sales, use, value-added, and goods and services taxes, to businesses like Nextdoor is a complex and evolving issue. Many of the fundamental statutes and regulations that impose these

taxes were established before the adoption and growth of the Internet and e-commerce. Significant judgment is required on an ongoing basis to evaluate applicable tax obligations and as a result amounts recorded are estimates and are subject to adjustments. In many cases, the ultimate tax determination is uncertain because it is not clear how new and existing statutes might apply to Nextdoor's business.

In addition, governments are increasingly looking for ways to increase revenue, which has resulted in discussions about tax reform and other legislative action to increase tax revenue, including through indirect taxes. For example, in November 2020, San Francisco voters approved Proposition F, which gradually increases the gross receipts tax rates (effective January 1, 2021) for companies doing business in San Francisco. Additionally, the State of Maryland enacted a digital advertising tax which could apply to Nextdoor effective January 1, 2022. Such taxes could adversely affect Nextdoor's business, operating results, and financial condition.

Nextdoor is subject to various indirect non-income taxes, such as payroll, sales, use, value-added and goods and services taxes in the United States and various foreign jurisdictions, and it may face indirect tax audits in various U.S. and foreign jurisdictions. In certain jurisdictions, Nextdoor collects and remits indirect taxes. However, tax authorities may question, challenge or disagree with Nextdoor's calculation, reporting or collection of taxes and may require Nextdoor to collect taxes in jurisdictions in which it does not currently do so or to remit additional taxes and interest, and could impose associated penalties and fees. A successful assertion by one or more tax authorities requiring Nextdoor to collect taxes in jurisdictions in which it does not currently do so or to collect additional taxes in a jurisdiction in which it currently collects taxes, could result in substantial tax liabilities, including taxes on past sales, as well as penalties and interest, could discourage neighbors from utilizing Nextdoor's platform or could otherwise harm Nextdoor's business, operating results, and financial condition.

Nextdoor could be subject to changes in tax rates, the adoption of new U.S. or international tax legislation, or exposure to additional tax liabilities.

Due to shifting economic and political conditions in both the United States and internationally, tax policies, laws, or rates in various jurisdictions may be subject to significant changes in ways that impair Nextdoor's financial results. Various jurisdictions around the world have enacted or are considering digital services taxes, which could lead to inconsistent and potentially overlapping international tax regimes. The Organization for Economic Cooperation and Development ('OECD') recently released proposals relating to its initiative for modernizing international tax rules, with the goal of having different countries implement a modernized and aligned international tax framework, but there can be no guarantee that this will occur.

If the Merger does not qualify as a reorganization under Section 368(a) of the Code, the stockholders of Nextdoor may be required to pay substantial U.S. federal income taxes.

The Merger is intended to qualify as a 'reorganization' within the meaning of Section 368(a) of the Code. In connection with the filing of this registration statement, Nextdoor is receiving an opinion of legal counsel, based on certain factual representations from Nextdoor and KVSB and certain customary factual assumptions, to the effect that the Merger will qualify as a 'reorganization.' However, this opinion is not binding on the IRS. Furthermore, it is not a condition to the completion of the Merger that either Nextdoor or KVSB receives an opinion of counsel as to the tax consequences of the Merger, and the Merger will occur even if it does not so qualify. No ruling has been, or will be, sought by Nextdoor or KVSB from the IRS with respect to the Merger and there can be no assurance that the IRS will not challenge the qualification of the Merger as a 'reorganization' under Section 368(a) of the Code or that a court would not sustain such a challenge. If the IRS or a court determines that the Merger should not be treated as a 'reorganization,' a holder of Nextdoor common stock would recognize gain or loss upon the taxable exchange of Nextdoor common stock for consideration pursuant to the Merger. See the section entitled 'U.S Federal Income Tax Considerations - Material U.S. Federal Income Tax Consequences of the Merger.'

Risks related to legal and regulatory matters

Nextdoor may be liable as a result of content or information that is published or made available on its platform.

Nextdoor is subject to many U.S. federal and state and foreign laws and regulations that involve matters central to its business, including laws and regulations that involve data privacy and protection, intellectual property

(including copyright and patent laws), content regulation, rights of publicity, advertising, marketing, health and safety, competition, protection of minors, consumer protection, taxation, anti-bribery, anti-money laundering and corruption, economic or other trade prohibitions or sanctions or securities law compliance. Although content on Nextdoor's platform is typically generated by third parties, and not by Nextdoor, Nextdoor may be sued or face regulatory liability for claims relating to content or information that is made available on its service, including claims of defamation, disparagement, intellectual property infringement, or other alleged damages could be asserted against Nextdoor. Nextdoor's systems, tools and personnel that help it to proactively detect potentially policy-violating or otherwise inappropriate content cannot identify all such content on its service, and in many cases this content will appear on the Nextdoor platform. This risk may increase as Nextdoor develops and increases the use of certain features, such as video, for which identifying such content is challenging. Additionally, some controversial content may not be banned on the Nextdoor platform and, even if it is not featured in advertisements to neighbors, it may still appear in the newsfeed or elsewhere. This risk is enhanced in certain jurisdictions outside of the United States where Nextdoor's protection from liability for content published on its platform by third parties may be unclear and where Nextdoor may be less protected under local laws than it is in the United States. Further, if policy-violating content is found on the Nextdoor platform, Nextdoor may be in violation of the terms of certain of its key agreements, which may result in termination of the agreement and potentially payment of damages in some cases. Nextdoor could incur significant costs in investigating and defending such claims and, if it is found liable, damages. If any of these events occur, Nextdoor's business, operating results, and financial condition could be harmed.

While Nextdoor relies on a variety of statutory and common-law frameworks and defenses, including those provided by the Digital Millennium Copyright Act, the Communications Decency Act ('CDA'), the fair-use doctrine in the United States and the Electronic Commerce Directive in the European Union, differences between statutes, limitations on immunity, requirements to maintain immunity, and moderation efforts in the many jurisdictions in which Nextdoor operates may affect its ability to rely on these frameworks and defenses, or create uncertainty regarding liability for information or content uploaded by neighbors and advertisers or otherwise contributed by third-parties to its platform.

Actions by governments that restrict access to Nextdoor's platform in their countries, or that otherwise impair Nextdoor's ability to sell advertising in their countries, could substantially harm Nextdoor's business, operating results, and financial condition.

Governments may seek to censor content available on Nextdoor's platform or restrict access to the platform from their country entirely, or impose other restrictions that may affect the accessibility of the platform in their country for an extended period of time or indefinitely. In addition, government authorities in other countries may seek to restrict neighbors' access to the platform if they consider Nextdoor to be in violation of their laws or a threat to public safety or for other reasons. It is possible that government authorities could take action that impairs Nextdoor's ability to sell advertising, including in countries where access to Nextdoor's consumer-facing platform may be blocked or restricted. In the event that content shown on Nextdoor's platform is subject to censorship, access to the platform is restricted, in whole or in part, in one or more countries, or other restrictions are imposed on the platform, or Nextdoor's competitors are able to successfully penetrate new geographic markets or capture a greater share of existing geographic markets that Nextdoor cannot access or where Nextdoor face other restrictions, Nextdoor's ability to retain or increase its neighbor base, neighbor engagement, or the level of advertising by advertisers may be adversely affected, Nextdoor may not be able to maintain or grow its revenue as anticipated, and its financial results could be adversely affected.

Nextdoor's business is subject to complex and evolving U.S. and foreign laws, regulations and industry standards, many of which are subject to change and uncertain interpretation, which uncertainty could harm Nextdoor's business, operating results, and financial condition.

Nextdoor is subject to many U.S. federal and state and foreign laws, regulations and industry standards that involve matters central to its business, including laws and regulations that involve data privacy, cybersecurity, intellectual property (including copyright and patent laws), content, rights of publicity, advertising, marketing, competition, protection of minors, consumer protection, taxation, and telecommunications. These laws and regulations are constantly evolving and may be interpreted, applied, created, or amended, in a manner that could harm Nextdoor's business. In addition, the introduction of new products, expansion of Nextdoor's activities in

certain jurisdictions, or other actions that Nextdoor may take may subject the company to additional laws, regulations, or other government scrutiny.

Nextdoor relies on a variety of statutory and common-law frameworks and defenses relevant to the content available on Nextdoor's platform, including the Digital Millennium Copyright Act, the CDA and the fair-use doctrine in the United States, and the Electronic Commerce Directive in the European Union. However, each of these statutes is subject to uncertain or evolving judicial interpretation and regulatory and legislative amendments. For example, in the United States, laws such as the CDA, which have previously been interpreted to provide substantial protection to interactive computer service providers, may change and become less predictable or unfavorable by legislative action or juridical interpretation. There have been various federal and state legislative efforts to restrict the scope of the protections available to online platforms under the CDA, in particular with regards to Section 230 of the CDA, and current protections from liability for third-party content in the United States could decrease or change. Nextdoor could incur significant costs investigating and defending such claims and, if it is found liable, significant damages.

The European Union is also reviewing the regulation of digital services, and has introduced the Digital Services Act ('DSA'), a package of legislation intended to update the liability and safety rules for digital platforms, products, and services, which could negatively impact the scope of the limited immunity provided by the E-Commerce Directive. Some European jurisdictions and the United Kingdom have also proposed or intend to pass legislation that imposes new obligations and liabilities on platforms with respect to certain types of harmful content. While the scope and timing of these proposals are currently uncertain, if the rules, doctrines or currently available defenses change, if international jurisdictions refuse to apply similar protections that are currently available in the United States or the European Union or if a court were to disagree with Nextdoor's application of those rules to its service, it could be required to expend significant resources to try to comply with the new rules or incur liability, and its business, operating results, and financial condition could be harmed.

Nextdoor collects, stores, uses, shares and otherwise processes data, some of which contains personal information about individuals including, but not limited to, its neighbors, employees and partners including, contact details, network details, and location data. Nextdoor is therefore subject to U.S. (federal, state, local) and foreign laws and regulations regarding data privacy and security and the processing of personal information and other data from neighbors, employees or business partners. The regulatory framework for privacy, information security, data protection and processing worldwide and interpretations of existing laws and regulations is likely to continue to be uncertain and current or future legislation or regulations in the United States and other jurisdictions, or new interpretations of existing laws and regulations, could significantly restrict or impose conditions on Nextdoor's ability to process data and increase notice or consent requirements before Nextdoor can utilize advertising technologies.

In the United States, Nextdoor is subject to numerous federal, state and local data privacy and security laws and regulations governing the processing of information about individuals. For example, the CCPA, which took effect in January 2020, establishes certain transparency obligations and creates new data privacy rights for users, including rights to access and delete their personal information as well as opt-out of certain sales or transfers of their personal information. The law also prohibits covered businesses from discriminating against consumers (for example, charging more for services) for exercising any of their CCPA rights. The CCPA imposes statutory damages for certain violations of the law as well as a private right of action for certain data breaches that result in the loss of personal information. This private right of action is expected to increase the likelihood of, and risks associated with, data breach litigation. It remains unclear how various provisions of the CCPA will be interpreted and enforced. Additionally, California voters approved a new privacy law, the CPRA, which becomes effective January 1, 2023 (with a look back to January 2022). The CPRA will significantly modify the CCPA, including by expanding consumers' rights and establishing a new state agency that will be vested with authority to implement and enforce the CCPA and the CPRA. For example, the CPRA and the CCPA may lead other states to pass comparable legislation, with potentially greater penalties, and more rigorous compliance requirements relevant to Nextdoor's business. Virginia and Colorado have enacted the Consumer Data Protection Act ('VCDPA') and the Colorado Data privacy Act ('CDPA'), respectively, which may impose obligations similar to or more stringent than those Nextdoor may face under other data protection laws. Compliance with the CPRA, the CCPA, the VCDPA, the CDPA and any newly enacted privacy and data security laws or regulations may be challenging and cost- and time-intensive, and

may require Nextdoor to modify its data processing practices and policies and to incur substantial costs and potential liability in an effort to comply with such legislation.

In the EEA, Nextdoor is subject to the GDPR and in the United Kingdom, Nextdoor is subject to the United Kingdom data protection regime consisting primarily of the UK GDPR and the UK Data Protection Act 2018, in each case in relation to Nextdoor's collection, control, processing, sharing, disclosure and other use of data relating to an identifiable living individual (personal data). The GDPR, and national implementing legislation in EEA member states and the United Kingdom, imposes a strict data protection compliance regime, grants new rights for data subjects in regard to their personal data (including the right to be 'forgotten' and the right to data portability) and enhances current rights (e.g., data subject access requests).

We are also subject to European Union rules with respect to cross-border transfers of personal data out of the EEA and the United Kingdom. Recent legal developments in Europe have created complexity and uncertainty regarding transfers of personal data from the EEA and the United Kingdom to the United States. On July 16, 2020, the Court of Justice of the European Union (the 'CJEU') invalidated the EU-U.S. Privacy Shield Framework, or Privacy Shield, under which personal data could be transferred from the EEA to U.S. entities who had self-certified under the Privacy Shield scheme. While the CJEU upheld the adequacy of the standard contractual clauses (a standard form of contract approved by the EU Commission as an adequate personal data transfer mechanism, and potential alternative to the Privacy Shield), it made clear that reliance on them alone may not necessarily be sufficient in all circumstances. Use of the standard contractual clauses must now be assessed on a case-by-case basis taking into account the legal regime applicable in the destination country, in particular applicable surveillance laws and rights of individuals and additional measures and/or contractual provisions may need to be put in place, however, the nature of these additional measures is currently uncertain. The CJEU went on to state that if a competent supervisory authority believes that the standard contractual clauses cannot be complied with in the destination country and the required level of protection cannot be secured by other means, such supervisory authority is under an obligation to suspend or prohibit that transfer. To safeguard data transfers from the EEA to other jurisdictions, including the USA, Nextdoor currently utilizes standard contractual contracts approved by the EU Commission.

This CJEU decision may result in different EEA data protection regulators applying differing standards for the transfer of personal data from the EEA to the United States, and even require ad hoc verification of measures taken with respect to data flows. Therefore, as a result of this CJEU decision, Nextdoor may be required to review, amend and take additional steps to legitimize impacted personal data transfers. As supervisory authorities issue further guidance on personal data export mechanisms, including circumstances where the standard contractual clauses cannot be used, and/or start taking enforcement action, Nextdoor could suffer increased costs to ensure compliance as well as additional complaints and/or regulatory investigations or fines, and/or if Nextdoor is otherwise unable to transfer personal data between and among countries and regions in which Nextdoor operates, it could affect the manner in which Nextdoor provides its services, the geographical location or segregation of its relevant systems and operations, and could adversely affect Nextdoor's business, financial condition and results of operations. The EU Commission has also published revised standard contractual clauses for data transfers from the EEA: the revised clauses must be used for relevant new data transfers from September 27, 2021; existing standard contractual clauses arrangements must be migrated to the revised clauses by December 27, 2022. Where Nextdoor continues to rely on standard contractual clauses, Nextdoor will need to implement the revised standard contractual clauses, in relation to relevant existing contracts and vendor/customer arrangements, within the relevant time frames. There is some uncertainty around whether the revised clauses can be used for all types of data transfers, particularly whether they can be relied on for data transfers to non-EEA entities subject to the GDPR.

The relationship between the United Kingdom and the European Union in relation to certain aspects of data protection law remains unclear, and it is unclear how U.K. data protection laws and regulations, including those regarding data transfers to and from the United Kingdom, will develop in the medium to longer term. For example, while the EU Commission has adopted an adequacy decision in favor of the United Kingdom, enabling data transfers from EU member states to the United Kingdom without additional safeguards, the decision will automatically expire in June 2025 unless the EU Commission re-assesses and renews/extends it. These developments and this uncertainty will lead to additional costs and increase our overall risk exposure.

We are also subject to evolving E.U. and U.K. privacy laws on cookies and e-marketing. In the E.U. and the U.K., regulators are increasingly focusing on compliance with current national laws that implement the European Directive 2002/58/EC (the 'ePrivacy Directive'). The ePrivacy Directive is highly likely to be replaced by an EU regulation known as the ePrivacy Regulation that will significantly increase fines for non-compliance. In the E.U. and the U.K., informed consent is required for the placement of certain cookies or similar technologies on a user's device and for direct electronic marketing and (under the UK GDPR and the GDPR) valid consent is tightly defined, including, a prohibition on pre-checked consents and, in the context of cookies, a requirement to obtain separate consents for each type of cookie or similar technology. While the text of the ePrivacy Regulation is still under development, a recent European court decision and regulators' recent guidance are driving increased attention to cookies and tracking technologies. If regulators start to enforce the strict approach in recent guidance, this could lead to substantial costs, require significant systems changes, limit the effectiveness of Nextdoor's marketing activities, divert the attention of Nextdoor's technology personnel, adversely affect Nextdoor's margins, increase costs and subject Nextdoor to additional liabilities. Regulation of cookies and similar technologies, and any decline of cookies or similar online tracking technologies as a means to identify and potentially target users, may lead to broader restrictions and impairments on Nextdoor's marketing and personalization activities and may negatively impact its efforts to understand users.

While Nextdoor has put in efforts to comply with these regulations, the uncertainty surrounding enforcement and changing privacy landscapes could change its compliance status. Similarly, there are a number of legislative proposals in the European Union, the United States, at both the federal and state level, as well as other jurisdictions that could impose new obligations or limitations in areas affecting Nextdoor's business.

The costs of complying with these laws and regulations, which in some cases can be enforced by private parties in addition to government entities, are high and likely to increase in the future, particularly as the degree of regulation increases, Nextdoor's business grows and its geographic scope expands. The impact of these laws and regulations may disproportionately affect Nextdoor's business in comparison to its peers in the technology sector that have greater resources. Even though Nextdoor communicates with lawmakers and regulators in countries and regions in which it conducts business, and despite Nextdoor having a dedicated policy team to monitor legal and regulatory developments, any failure or perceived failure of compliance on Nextdoor's part to comply with the laws and regulations may subject it to significant liabilities or penalties, or otherwise adversely affect its business, financial condition or operating results. Furthermore, it is possible that certain governments may seek to block or limit Nextdoor's products or otherwise impose other restrictions that may affect the accessibility or usability of any or all its products for an extended period of time or indefinitely.

Nextdoor could be involved in legal disputes that are expensive and time consuming, and, if resolved adversely, could harm its business, operating results, and financial condition.

Nextdoor is currently involved in, and may in the future be involved in, actual and threatened legal proceedings, claims, investigations and government inquiries arising in the ordinary course of its business, including intellectual property, data privacy, cybersecurity, privacy and other torts, illegal or objectionable content, consumer protection, securities, stockholder derivative claims, employment, governance, workplace culture, contractual rights, civil rights infringement, false or misleading advertising, or other legal claims relating to content or information that is provided to Nextdoor or published or made available on its platform. Any proceedings, claims or inquiries involving Nextdoor, whether successful or not, may be time consuming, result in costly litigation, unfavorable outcomes, increased costs of business, may require Nextdoor to change its business practices or platform, require significant amount of management's time, may harm Nextdoor's reputation or otherwise harm its business, operating results, and financial condition.

Nextdoor is currently involved in and has been subject to actual and threatened litigation with respect to third-party patents, trademarks, copyrights and other intellectual property, and may continue to be subject to intellectual property litigation and threats thereof. Companies in the internet, technology and media industries own large numbers of patents, copyrights, trademarks and trade secrets and frequently enter into litigation based on allegations of infringement or other violations of intellectual property rights. As Nextdoor faces increasing competition, grows its business and platform offerings, and becomes increasingly high profile, the possibility of receiving a larger number of intellectual property claims against the company grows. In addition, various 'non-practicing entities' that

own patents and other intellectual property rights have asserted, and may in the future attempt to assert, intellectual property claims against Nextdoor to extract value through licensing or other settlements.

From time to time, Nextdoor receives letters from patent holders alleging that Nextdoor's platform infringes on their patent rights and from trademark holders alleging infringement of their trademark rights. Nextdoor also receives letters from holders of copyrighted content alleging infringement of their intellectual property rights. Nextdoor's technologies and content, including the content that neighbors upload to the platform, may not be able to withstand such third-party claims.

With respect to any intellectual property claims, Nextdoor may have to seek a license to continue using technologies or engaging in practices found to be in violation of a third-party's rights, which may not be available on reasonable terms and may significantly increase Nextdoor's operating expenses. A license to continue such technologies or practices may not be available to Nextdoor at all and it may be required to discontinue use of such technologies or practices or to develop alternative non-infringing technologies or practices. The development of alternative non-infringing technologies or practices could require significant effort and expense or may not be achievable at all. Nextdoor's business, operating results, and financial condition could be harmed as a result.

Exposure to United Kingdom political developments, including the effect of its withdrawal from the European Union, could be costly and difficult to comply with and could adversely impact Nextdoor's business, operations results, and financial condition.

In June 2016, a referendum was passed in the United Kingdom to leave the European Union, commonly referred to as 'Brexit.' This decision created an uncertain political and economic environment in the United Kingdom and other European Union countries, and the formal process for leaving the European Union has taken years to complete. Although the United Kingdom and the European Union have recently entered into a trade and cooperation agreement, the long-term nature of the United Kingdom's relationship with the European Union remains unclear and there is considerable uncertainty as to their future political and economic relations. The political and economic instability created by Brexit has caused and may continue to cause significant volatility in global financial markets and uncertainty regarding the regulation of cybersecurity in the United Kingdom. In addition, Brexit could lead to legal uncertainty and potentially divergent national laws and regulations as the United Kingdom determines which European Union laws to replace or replicate. For example, as discussed above, although the European Commission has adopted an adequacy decision in favor of the United Kingdom, enabling data transfers from EU member states to the United Kingdom without additional safeguards, uncertainty remains regarding how data transfers to and from the United Kingdom will be regulated in the long term. Brexit could also have the effect of disrupting the free movement of goods, services, capital, and people between the United Kingdom, the European Union, and elsewhere. The full effect of Brexit is uncertain and depends on any current and future agreements the United Kingdom makes with the European Union and others. Consequently, no assurance can be given about the impact of these developments, and Nextdoor's operational, tax, and other policies may require reassessment and Nextdoor's business, operating results, and financial condition may be seriously harmed.

The obligations associated with operating as a public company following the Business Combination will require significant resources and management attention and will cause Nextdoor to incur additional expenses, which will adversely affect its profitability.

Following the Business Combination, Nextdoor's expenses will increase as a result of the additional accounting, legal and various other additional expenses usually associated with operating as a public company and complying with public company disclosure obligations. As a non-public company, Nextdoor is not required to comply with certain corporate governance and financial reporting practices and policies required of a publicly traded company. After the Business Combination, Nextdoor will be required to comply with certain requirements of the Exchange Act, the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the 'Dodd-Frank Act'), and other applicable securities rules and regulations. The Exchange Act requires, among other things, that Nextdoor files annual, quarterly, and current reports with respect to its business and operating results with the SEC. Nextdoor will also be required to ensure that it has the ability to prepare financial statements that are fully compliant with all SEC reporting requirements on a timely basis. Compliance with these rules and regulations will increase Nextdoor's legal and financial compliance costs, make some activities more difficult, time-consuming

or costly and increase demand on Nextdoor's systems and resources. As a public company, Nextdoor will, among other things:

•prepare and distribute periodic public reports and other stockholder communications in compliance with its obligations under the federal securities laws;

•create or expand the roles and duties of its board of directors and committees of the board;

•institute more comprehensive financial reporting and disclosure compliance functions; and

•establish new and enhance existing internal policies, including those relating to disclosure controls and procedures.

These changes, and the additional involvement of accountants and legal advisors, will require a significant commitment of additional resources. Nextdoor might not be successful in complying with these obligations and the significant commitment of resources required for complying with them could have a material adverse effect on its business, financial condition, results of operations and cash flows. If Nextdoor's efforts to comply with new laws, regulations and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to practice, regulatory authorities may initiate legal proceedings against Nextdoor, and Nextdoor's business may be harmed. Moreover, in connection with this Business Combination, Nextdoor intends to increase its directors' and officers' insurance coverage, which will increase Nextdoor's insurance cost. In the future, it may be more expensive or more difficult for Nextdoor to obtain director and officer liability insurance, and Nextdoor may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These factors would also make it more difficult for Nextdoor to attract and retain qualified members of Nextdoor's board of directors, particularly to serve on Nextdoor's audit and risk committee and compensation committee, and qualified executive officers.

Failure to maintain effective systems of internal control and disclosure controls could have a material adverse effect on Nextdoor's business, operating results, and financial condition.

Effective internal and disclosure controls are necessary for Nextdoor to provide reliable financial reports and effectively prevent fraud and to operate successfully as a public company. As a public company, Nextdoor will be required by the Sarbanes-Oxley Act to design and maintain a system of internal control over financial reporting and disclosure controls and procedures. If Nextdoor cannot provide reliable financial reports or prevent fraud, its reputation and operating results would be harmed.

Nextdoor's current controls and any new controls it develops may become inadequate because of changes in conditions in our business. Further, weaknesses in Nextdoor's internal controls may be discovered in the future. Any failure to develop or maintain effective controls, or any difficulties encountered in their implementation or improvement, could harm Nextdoor's operating results, may result in a restatement of its financial statements for prior periods, cause it to fail to meet its reporting obligations, and could adversely affect the results of periodic management evaluations and annual independent registered public accounting firm attestation reports regarding the effectiveness of its internal control over financial reporting that it is required to include in the periodic reports it will file with the SEC. However, while, following the Business Combination, New Nextdoor remains an 'emerging growth company,' New Nextdoor will not be required to include an attestation report on internal control over financial reporting issued by its independent registered public accounting firm. Ineffective disclosure controls and procedures and internal control over financial reporting could also cause investors to lose confidence in New Nextdoor's reported financial and other information, which would likely have a negative effect on the market price of its Class A common stock. Nextdoor is not currently required to comply with the SEC rules that implement Sections 302 and 404 of the Sarbanes-Oxley Act, and it is therefore not required to make a formal assessment of the effectiveness of its internal control over financial reporting for that purpose.

Upon becoming a public company, and particularly after New Nextdoor is no longer an 'emerging growth company,' significant resources and management oversight will be required. As a result, management's attention may be diverted from other business concerns, which could harm New Nextdoor's business, operating results and financial condition.

Risks related to intellectual property

If Nextdoor is unable to protect its intellectual property, the value of its brands and other intangible assets may be diminished, and its business, operating results, and financial condition may be adversely affected.

Nextdoor relies and expects to continue to rely on a combination of confidentiality, assignment, and license agreements with its employees, consultants, and third parties with whom it has relationships, as well as trademark, copyright, patent, trade secret, and domain name protection laws, to protect its proprietary rights. In the United States and internationally, Nextdoor has filed various applications for protection of certain aspects of its intellectual property, and Nextdoor currently holds issued patents and copyrights in the United States, issued copyrights in the United States, and multiple trademark registrations in the United States and other foreign countries. Third parties may knowingly or unknowingly infringe Nextdoor's proprietary rights, third parties may challenge proprietary rights held by Nextdoor, and pending and future trademark and patent applications may not be approved.

Any issued patents may be challenged, invalidated or circumvented, and any rights granted under these patents may not actually provide adequate defensive protection or competitive advantages to Nextdoor. Patent applications in the U.S. are typically not published until at least 18 months after filing, or, in some cases, not at all. Nextdoor cannot be certain that it was the first to make the inventions claimed in its pending patent applications or that it was the first to file for patent protection. Additionally, the process of obtaining patent protection is expensive and time-consuming, and Nextdoor may not be able to prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. Recent changes to the patent laws in the U.S. may also bring into question the validity of certain software patents and may make it more difficult and costly to prosecute patent applications. Such changes may lead to uncertainties or increased costs and risks surrounding the prosecution, validity, ownership, enforcement, and defense of its issued patents and patent applications and other intellectual property, the outcome of third-party claims of infringement, misappropriation, or other violation of intellectual property brought against Nextdoor and the actual or enhanced damages (including treble damages) that may be awarded in connection with any such current or future claims, and could have a material adverse effect on Nextdoor's business.

Nextdoor relies on its trademarks, trade names, and brand names to distinguish its platform from the products of its competitors. However, third parties may have already registered identical or similar marks for products or solutions that also address the software market. Efforts by third parties to limit use of Nextdoor's brand names or trademarks and barriers to the registration of brand names and trademarks may restrict its ability to promote and maintain a cohesive brand throughout Nextdoor's key markets. There can also be no assurance that pending or future U.S. or foreign trademark applications will be approved in a timely manner or at all, or that such registrations will effectively protect Nextdoor's brand names and trademarks. Third parties may also oppose Nextdoor's trademark applications, or otherwise challenge Nextdoor's use of the trademarks. In the event that Nextdoor's trademarks are successfully challenged, Nextdoor could be forced to rebrand its platform, which would result in loss of brand recognition and would require it to devote resources to advertising and marketing new brands.

In addition, effective intellectual property protection may not be available in every country in which Nextdoor operates or intends to operate its business. In any or all of these cases, Nextdoor may be required to expend significant time and expense in order to prevent infringement or to enforce its rights. Although Nextdoor has generally taken measures to protect its proprietary rights, there can be no assurance that others will not offer products or concepts that are substantially similar to Nextdoor's and compete with its business. If the protection of Nextdoor's proprietary rights is inadequate to prevent unauthorized use or appropriation by third parties, the value of its brands and other intangible assets may be diminished and competitors may be able to more effectively mimic Nextdoor's platform and methods of operations.

To prevent substantial unauthorized use of Nextdoor's intellectual property rights, it may be necessary to prosecute actions for infringement and/or misappropriation of Nextdoor's proprietary rights against third parties. Any such action could result in significant costs and diversion of its resources and management's attention, and Nextdoor cannot assure that it will be successful in such action. Furthermore, many of Nextdoor's current and potential competitors have the ability to dedicate substantially greater resources to enforce their intellectual property rights (or to contest claims of infringement) than Nextdoor does. Accordingly, despite Nextdoor's efforts, it may not be able to prevent third parties from knowingly or unknowingly infringing upon, misappropriating or circumventing

its intellectual property rights. If Nextdoor is unable to protect its proprietary rights (including aspects of its software and platform protected other than by patent rights), it will find itself at a competitive disadvantage to others who need not incur the additional expense, time and effort required to create its platform. Moreover, Nextdoor may need to expend additional resources to defend its intellectual property rights in foreign countries, and its inability to do so could impair its business, results of operations and financial condition or adversely affect its business, operating results, and financial condition.

Confidentiality agreements with employees and others may not adequately prevent disclosure of trade secrets and proprietary information.

Nextdoor has devoted substantial resources to the development of its intellectual property and proprietary rights. To protect its intellectual property and proprietary rights, Nextdoor relies in part on confidentiality agreements with its employees, vendors, licensees, independent contractors and other advisors. These agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. Effective trade secret protection may also not be available in every country in which Nextdoor's platform is available or where it has employees or independent contractors. The loss of trade secret protection could make it easier for third parties to compete with Nextdoor's platform by copying functionality. In addition, any changes in, or unexpected interpretations of, the trade secret and employment laws in any country in which it operates may compromise its ability to enforce its trade secret and intellectual property rights. In addition, others may independently discover trade secrets and proprietary information and in such cases, Nextdoor could not assert any trade secret rights against such parties. Costly and time-consuming litigation could be necessary to enforce and determine the scope of Nextdoor's proprietary rights and failure to obtain or maintain trade secret protection could adversely affect its competitive business position.

Third parties may claim that Nextdoor's platform infringes their intellectual property rights and this may create liability for Nextdoor or otherwise adversely affect its business, operating results and financial condition.

Third parties may claim that Nextdoor's platform infringes their intellectual property rights, and such claims may result in legal claims against Nextdoor and its technology partners and customers. These claims may damage Nextdoor's brand and reputation and create liability for Nextdoor. Nextdoor expects the number of such claims to increase as the functionality of Nextdoor's platform overlaps with that of other products and services, and as the volume of issued software patents and patent applications continues to increase.

Companies in the software and technology industries own large numbers of patents, copyrights, trademarks, and trade secrets and frequently enter into litigation based on allegations of infringement or other violations of intellectual property rights. In addition, many of these companies have the capability to dedicate substantially greater resources to enforce their intellectual property rights and to defend claims that may be brought against them. Furthermore, patent holding companies, non-practicing entities, and other adverse patent owners that are not deterred by its existing intellectual property protections may seek to assert patent claims against Nextdoor. Nextdoor has received, and may in the future receive, notices that claim it has misappropriated, misused, or infringed other parties' intellectual property rights, and, to the extent Nextdoor gains greater market visibility, Nextdoor may face a higher risk of being the subject of intellectual property infringement claims.

Nextdoor may also face exposure to third party intellectual property infringement, misappropriation, or violation actions if Nextdoor engages software engineers or other personnel who were previously engaged by competitors or other third parties and those personnel inadvertently or deliberately incorporate proprietary technology of third parties into its products. In addition, Nextdoor may lose valuable intellectual property rights or personnel. A loss of key personnel or their work product could hamper or prevent Nextdoor's ability to develop, market and support potential products or enhancements, which could severely harm its business. Any intellectual property claims, with or without merit, could be very time-consuming, could be expensive to settle or litigate, and could divert its management's attention and other resources. These claims could also subject Nextdoor to significant liability for damages, potentially including treble damages if Nextdoor is found to have willfully infringed patents or copyrights. These claims could also result in Nextdoor having to stop using technology found to be in violation of a third party's rights. Nextdoor might be required to seek a license for the intellectual property, which may not be available on reasonable terms or at all. Even if a license were available, Nextdoor could be required to pay

significant royalties, which would increase its operating expenses. Alternatively, Nextdoor could be required to develop alternative non-infringing technology, which could require significant time, effort, and expense, and may affect the performance or features of its platform. If Nextdoor cannot license or develop alternative non-infringing substitutes for any infringing technology used in any aspect of its business, Nextdoor would be forced to limit use of its platform. Any of these results would adversely affect Nextdoor's business, operating results and financial condition.

Nextdoor's use of 'open source' software could subject it to possible litigation or could prevent it from offering products that include open source software or require it to obtain licenses on unfavorable terms.

A portion of the technologies Nextdoor uses incorporates 'open source' software, and Nextdoor may incorporate open source software in the future. Open source software is generally licensed by its authors or other third parties under open source licenses. These licenses may subject Nextdoor to certain unfavorable conditions, including requirements that Nextdoor offer its products that incorporate the open source software for no cost, that Nextdoor make publicly available the source code for any modifications or derivative work it creates based upon, incorporating or using the open source software, or that Nextdoor license such modifications or derivative works under the terms of the particular open source license. From time to time, companies that use third-party open source software have also faced claims challenging the use of such open source software and their compliance with the terms of the applicable open source license. Nextdoor may be subject to suits by parties claiming ownership of what it believes to be open source software, or claiming non-compliance with the applicable open source licensing terms.

In addition to using open source software, Nextdoor also licenses to others some of its software through open source projects. Open sourcing Nextdoor's own software requires the company to make the source code publicly available, and therefore can affect its ability to protect Nextdoor's intellectual property rights with respect to that software. Additionally, if a third-party software provider has incorporated open source software into software that Nextdoor licenses from such provider, it could be required to disclose any of its source code that incorporates or is a modification or derivative work of such licensed software. If an author or other third party that distributes open source software that Nextdoor uses or licenses were to allege that Nextdoor had not complied with the conditions of the applicable license, Nextdoor could be required to incur significant legal expenses defending against such allegations and could be subject to significant damages, enjoined from offering its products that contained the open source software, required to release proprietary source code, required to obtain licenses from third parties or otherwise required to comply with the unfavorable conditions unless and until Nextdoor can re-engineer the product so that it complies with the open source license or does not incorporate the open source software.

The terms of many open source licenses have not been interpreted by U.S. or foreign courts, and accordingly there is a risk that those licenses could be construed in a manner that imposes unanticipated conditions or restrictions on Nextdoor's ability to commercialize its platform. In that event, Nextdoor could be required to seek licenses from third parties in order to continue offering its platform, to re‑develop its platform, or to release its proprietary source code under the terms of an open source license, any of which could harm Nextdoor's business. Enforcement activity for open source licenses can also be unpredictable. Were it determined that Nextdoor's use was not in compliance with a particular license, it may be required to release its proprietary source code, defend claims, pay damages for breach of contract or copyright infringement, grant licenses to its patents, re-engineer its platform, or take other remedial action that may divert resources away from its product development efforts, any of which could negatively impact its business. Open source compliance problems can also result in damage to reputation and challenges in recruitment or retention of engineering personnel. Further, given the nature of open source software, it may be more likely that third parties might assert copyright and other intellectual property infringement claims against Nextdoor based on Nextdoor's use of these open source software programs. Litigation could be costly for Nextdoor to defend, have a material adverse effect on its business, results of operations and financial condition, or require Nextdoor to devote additional development resources to change its platform.

Nextdoor licenses technology from third parties, and Nextdoor's inability to maintain those licenses could harm its business.

Nextdoor currently incorporates, and will in the future continue to incorporate, technology that it licenses from third parties, including software, into its platform. Licensing technologies from third parties exposes Nextdoor to

increased risk of being the subject of intellectual property infringement due to, among other things, its lower level of visibility into the development process with respect to such technology and the care taken to safeguard against infringement risks. Nextdoor cannot be certain that its licensors do not or will not infringe on the intellectual property rights of third parties or that its licensors have or will have sufficient rights to the licensed intellectual property in all jurisdictions in which Nextdoor operates. Some of Nextdoor's agreements with its licensors may be terminated by them for convenience, or otherwise provide for a limited term. If Nextdoor is unable to continue to license technology because of intellectual property infringement claims brought by third parties against its licensors or against us, or if Nextdoor is unable to continue its license agreements or enter into new licenses on commercially reasonable terms, Nextdoor's ability to develop its platform that is dependent on that technology would be limited, and Nextdoor's business could be harmed. Additionally, if Nextdoor is unable to license technology from third parties, Nextdoor may be forced to acquire or develop alternative technology, which it may be unable to do in a commercially feasible manner or at all, and may require Nextdoor to use alternative technology of lower quality or performance standards. As a result, Nextdoor's business, operating results and financial condition would be adversely affected.

Risks Related to the Business Combination and KVSB, and SPACs Generally

Unless the context otherwise requires, all references in this subsection to the 'Company,' 'we,' 'us' or 'our' refer to KVSB prior to the consummation of the Business Combination and New Nextdoor following the consummation of the Business Combination.

The Sponsor and our directors and officers have agreed to vote their founder shares, private placement shares and any shares of public common stock in favor of the Business Combination, regardless of how KVSB's public stockholders vote.

Unlike some other blank check companies in which the initial stockholders agree to vote their shares in accordance with the majority of the votes cast by the public stockholders in connection with an initial business combination, the Sponsor and our directors and officers have agreed, pursuant to the terms of the Sponsor Support Agreement, to vote their founder shares, private placement shares and any public shares held by them in favor of the Business Combination. As a result, in addition to the founder shares and private placement shares, we would need 17,750,863, or 37.2% (assuming all issued and outstanding shares are voted), or 5,809,088, or 12.2% (assuming only the minimum number of shares representing a quorum are voted), of the 41,634,412 public shares of KVSB common stock sold in our initial public offering to be voted in favor of the Business Combination (including the Merger) in order to have such Business Combination approved. We expect that the Sponsor and our directors and officers will own approximately 12.8% of our issued and outstanding KVSB common stock at the time of any such stockholder vote. Accordingly, if we seek stockholder approval of our initial Business Combination, it is more likely that the necessary stockholder approval will be received than would be the case if such persons agreed to vote their founder shares in accordance with the majority of the votes cast by our public stockholders.

Neither the KVSB board of directors nor any committee thereof obtained a third-party valuation in determining whether or not to pursue the Business Combination.

Neither the KVSB board of directors nor any committee thereof is required to obtain an opinion that the price that we are paying for Nextdoor is fair to us from a financial point of view. Neither the KVSB board of directors nor any committee thereof obtained a third-party valuation in connection with the Business Combination. In analyzing the Business Combination, among other things, the KVSB board of directors and management, together with its legal, accounting and other advisors, conducted due diligence on Nextdoor. The KVSB board of directors reviewed comparisons of selected financial data of Nextdoor with its peers in the industry and the financial terms set forth in the Merger Agreement, and concluded that the Business Combination was in the best interest of KVSB's stockholders. Accordingly, investors will be relying solely on the judgment of the KVSB board of directors and management in valuing Nextdoor, and the KVSB board of directors and management may not have properly valued such businesses. The lack of a third-party valuation may also lead an increased number of stockholders to vote against the Business Combination or demand redemption of their shares, which could potentially impact our ability to consummate the Business Combination.

Our ability to seek an alternative business combination is limited even if we determine the Business Combination is no longer in our stockholders' best interest.

If we do not obtain stockholder approval at the special meeting, Nextdoor can continually obligate us to hold additional special meetings to vote on the Condition Precedent Proposals until the earlier of such stockholder approval being obtained and the Agreement End Date. This could limit our ability to seek an alternative business combination that our stockholders may prefer after such initial vote.

Since the Sponsor and KVSB's directors and executive officers have interests that are different, or in addition to (and which may conflict with), the interests of our stockholders, a conflict of interest may have existed in determining whether the Business Combination with Nextdoor is appropriate as our initial business combination. Such interests include that Sponsor will lose its entire investment in us if our business combination is not completed.

When you consider the recommendation of the KVSB Board in favor of approval of the proposals in this proxy statement/prospectus, you should keep in mind that the Sponsor and KVSB's directors and executive officers have interests in the Business Combination that may be different from, or in addition to, those of KVSB stockholders generally. The existence of financial and personal interests of one or more of KVSB's directors may result in a conflict of interest on the part of such director(s) between what he, she or they believe is in the best interests of KVSB and its stockholders and what he, she or they may believe is best for himself, herself or themselves in determining to recommend the stockholders vote for the proposals. In addition, KVSB's officers may have interests in the Business Combination that may conflict with your interests as a stockholder. These interests include, among other things, the interests listed below:

•Prior to KVSB's initial public offering, the Sponsor purchased 10,000,000 founder shares, at $0.0025 per share. Subsequent to the share capitalization, the Sponsor transferred 40,000 founder shares to each of Dmitri Shklovsky, Anita Sands and Enrico Gaglioti, KVSB's independent directors. If KVSB does not consummate a business combination by the Liquidation Date, it would cease all operations except for the purpose of winding up, redeeming all of the outstanding public shares for cash and, subject to the approval of its remaining stockholders and its board of directors, dissolving and liquidating, subject in each case to its obligations under the DGCL to provide for claims of creditors and the requirements of other applicable law. In such event, the 10,000,000 founder shares owned by the Sponsor and KVSB's independent directors would be worthless because following the redemption of the public shares, KVSB would likely have few, if any, net assets and because the Sponsor and KVSB's directors and officers have agreed to waive their respective rights to liquidating distributions from the trust account in respect of the 10,000,000 founder shares held by it if KVSB fails to complete a business combination within the required period. Additionally, in such event, the 1,132,688 private placement shares purchased by the Sponsor simultaneously with the consummation of the initial public offering for an aggregate purchase price of $11,326,880, will also expire worthless. Mr. Kaul, KVSB's Chairman and Chief Executive Officer, also has an economic interest in such private placement shares and in the 9,880,000 founder shares owned by the Sponsor. The 10,232,269 shares of New Nextdoor Class B common stock into which the 9,880,000 founder shares held by the Sponsor will convert and be exchanged, or reclassified, in connection with the Merger, if unrestricted, fully vested and freely tradable, would have had an aggregate market value of approximately $ million based upon the closing price of $ per share on Nasdaq on , 2021, the most recent practicable date prior to the date of this proxy statement/prospectus. However, given that such shares of New Nextdoor Class B common stock will be subject to certain restrictions, including those described above, KVSB believes such shares have less value. The 176,334 shares of New Nextdoor Class B common stock into which the 120,000 founder shares held by KVSB's independent directors will convert and be exchanged in connection with the Merger, if unrestricted and freely tradable, would have had an aggregate market value of approximately $ million based upon the closing price of $ per share on the Nasdaq on , 2021, the most recent practicable date prior to the date of this proxy statement/prospectus. The 1,132,688 shares of New Nextdoor Class B common stock into which the 1,132,688 private placement shares held by the Sponsor will be exchanged in connection with the Merger, if unrestricted and freely tradable, would have had an aggregate market value of approximately

$ million based upon the closing price of $ per share on the Nasdaq on , 2021, the most recent practicable date prior to the date of this proxy statement/prospectus.

•The Sponsor (including its representatives and affiliates) and KVSB's directors and officers, are, or may in the future become, affiliated with entities that are engaged in a similar business to KVSB. For example, certain officers and directors of KVSB, who may be considered an affiliate of the Sponsor, have also recently incorporated Khosla Ventures Acquisition Co. ('KVSA'), Khosla Ventures Acquisition Co. III ('KVSC') and Khosla Ventures Acquisition Co. IV ('KVSD'), each of which is a blank check company incorporated as a Delaware corporation for the purpose of effecting their respective initial business combinations. Samir Kaul is Chairman and Chief Executive Officer and Peter Buckland is Chief Operating Officer, Chief Financial Officer, Treasurer and Secretary of each of KVSA, KVSC and KVSD. Additionally, Dmitry Shklovsky is a director of KVSA. The Sponsor and KVSB's directors and officers are not prohibited from sponsoring, or otherwise becoming involved with, any other blank check companies prior to KVSB completing its initial business combination. Moreover, certain of KVSB's directors and officers have time and attention requirements for investment funds of which affiliates of the Sponsor are the investment managers. KVSB's directors and officers also may become aware of business opportunities which may be appropriate for presentation to KVSB, and the other entities to which they owe certain fiduciary or contractual duties, including KVSA, KVSC and KVSD. Accordingly, they may have had conflicts of interest in determining to which entity a particular business opportunity should be presented and KVSB's Existing Organizational Documents provide that KVSB renounces its interest in any corporate opportunity offered to any director or officer of KVSB. However, we do not believe that these conflicts materially impacted KVSB's search for an acquisition target because our management team has significant experience in identifying and executing multiple acquisition opportunities simultaneously and we were not limited by industry or geography in terms of the acquisition opportunities we could pursue.

•The Sponsor Related PIPE Investor has subscribed for $7.5 million of the PIPE Investment, for which they will receive up to 750,000 shares of New Nextdoor Class A common stock. Mr. Kaul has an economic interest in the Sponsor Related PIPE Investor. The 750,000 shares of New Nextdoor Class A common stock which the Sponsor Related PIPE Investor has subscribed for in the PIPE Investment, if unrestricted and freely tradable, would have had an aggregate market value of approximately $ million based upon the closing price of $ per share on Nasdaq on , 2021, the most recent practicable date prior to the date of this proxy statement/prospectus.

investigating possible business targets and business combinations. KVSB expects to incur approximately $28.3 million of transaction expenses (excluding the deferred underwriting commissions being held in the trust account), and to the extent that KVSB's officers and directors or their affiliates are advancing any of these expenses on behalf of KVSB, they are entitled to reimbursement of such payments. However, if KVSB fails to consummate a business combination by the Liquidation Date, they will not have any claim against the trust account for reimbursement. Accordingly, KVSB may not be able to reimburse the expenses advanced by KVSB's officers and directors or their affiliates if the Business Combination, or another business combination, is not completed by the Liquidation Date.

The personal and financial interests of the Sponsor and KVSB's directors and officers may have influenced their motivation in identifying and selecting Nextdoor as a business combination target, completing an initial business combination with Nextdoor and influencing the operation of the business following the initial business combination. In considering the recommendations of the KVSB Board to vote for the proposals, its stockholders should consider these interests.

The exercise of KVSB's directors' and executive officers' discretion in agreeing to changes or waivers in the terms of the Business Combination may result in a conflict of interest when determining whether such changes to the terms of the Business Combination or waivers of conditions are appropriate and in KVSB's stockholders' best interest.

In the period leading up to the Closing, events may occur that, pursuant to the Merger Agreement, would require KVSB to agree to amend the Merger Agreement, to consent to certain actions taken by Nextdoor or to waive rights that KVSB is entitled to under the Merger Agreement. Such events could arise because of changes in the course of Nextdoor's business or a request by Nextdoor to undertake actions that would otherwise be prohibited by the terms of the Merger Agreement. In any of such circumstances, it would be at KVSB's discretion to grant its consent or waive those rights. The existence of financial and personal interests of one or more of the directors or officers described in the preceding risk factors (and described elsewhere in this proxy statement/prospectus) may result in a conflict of interest on the part of such director(s) or officers(s) between what he, she or they may believe is best for KVSB and its stockholders and what he, she or they may believe is best for himself, herself or themselves in determining whether or not to take the requested action.

We and Nextdoor will incur significant transaction and transition costs in connection with the Business Combination.

We and Nextdoor have both incurred and expect to incur significant, non-recurring costs in connection with consummating the Business Combination and operating as a public company following the consummation of the Business Combination. We and Nextdoor may also incur additional costs to retain key employees. Certain transaction expenses incurred in connection with the Merger Agreement (including the Business Combination), including all legal, accounting, consulting, investment banking and other fees, expenses and costs, will be paid by New Nextdoor following the closing of the Business Combination.

The announcement of the proposed Business Combination could disrupt New Nextdoor's relationships with its neighbors, business partners and others, as well as its operating results and business generally.

Whether or not the Business Combination and related transactions are ultimately consummated, as a result of uncertainty related to the proposed transactions, risks relating to the impact of the announcement of the Business Combination on New Nextdoor's business include the following:

•its employees may experience uncertainty about their future roles, which might adversely affect New Nextdoor's ability to retain and hire key personnel and other employees;

•neighbors, business partners and other parties with which New Nextdoor maintains business relationships may experience uncertainty about its future and seek alternative relationships with third parties, seek to alter their business relationships with New Nextdoor or fail to extend an existing relationship with New Nextdoor; and

•New Nextdoor has expended and will continue to expend significant costs, fees and expenses for professional services and transaction costs in connection with the proposed Business Combination.

If any of the aforementioned risks were to materialize, they could lead to significant costs which may impact New Nextdoor's operating results and cash available to fund its business.

Subsequent to consummation of the Business Combination, we may be exposed to unknown or contingent liabilities and may be required to subsequently take write-downs or write-offs, restructuring and impairment or other charges that could have a significant negative effect on our financial condition, operating results and our share price, which could cause you to lose some or all of your investment.

We cannot assure you that the due diligence conducted in relation to Nextdoor has identified all material issues or risks associated with Nextdoor, its business or the industry in which it competes. Furthermore, we cannot assure you that factors outside of Nextdoor's and our control will not later arise. As a result of these factors, we may be exposed to liabilities and incur additional costs and expenses and we may be forced to later write-down or write-off assets, restructure our operations, or incur impairment or other charges that could result in our reporting losses. Even if our due diligence has identified certain risks, unexpected risks may arise and previously known risks may materialize in a manner not consistent with our preliminary risk analysis. If any of these risks materialize, this could have a material adverse effect on our financial condition and operating results and could contribute to negative market perceptions about our securities or New Nextdoor. Additionally, we have no indemnification rights against the Nextdoor Stockholders under the Merger Agreement and all of the purchase price consideration will be delivered at the Closing.

Accordingly, any stockholders of KVSB who choose to remain New Nextdoor stockholders following the Business Combination could suffer a reduction in the value of their shares. Such stockholders are unlikely to have a remedy for such reduction in value unless they are able to successfully claim that the reduction was due to the breach by our directors or officers of a duty of care or other fiduciary duty owed to them, or if they are able to successfully bring a private claim under securities laws that the registration statement or proxy statement/prospectus relating to the Business Combination contained an actionable material misstatement or material omission.

The Nextdoor projected financial information considered by KVSB may not be realized, which may adversely affect the market price of New Nextdoor Class A common stock following the completion of the Business Combination.

In performing its financial analyses, KVSB relied on, among other things, certain information, including the forecasts and financial projections described in the section entitled 'BCA Proposal - Projected Financial Information.' The Nextdoor forecasts and financial projections were prepared by, or at the direction of, the management of Nextdoor. None of these projections or forecasts were prepared with a view towards public disclosure or compliance with the published guidelines of the SEC, GAAP or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of financial forecasts. These projections and forecasts are inherently based on various estimates and assumptions that are subject to the judgment

of those preparing them. These projections and forecasts are also subject to significant economic, competitive, industry and other uncertainties and contingencies, all of which are difficult or impossible to predict and many of which are beyond the control of Nextdoor. There can be no assurance that Nextdoor's financial condition and operating results will be consistent with those set forth in such projections and forecasts, which could have an adverse impact on the market price of New Nextdoor Class A common stock or the financial position of Nextdoor following the Business Combination.

The unaudited pro forma financial information included elsewhere in this proxy statement/prospectus may not be indicative of what New Nextdoor's actual financial position or results of operations would have been.

The unaudited pro forma financial information in this proxy statement/prospectus is presented for illustrative purposes only and has been prepared based on a number of assumptions including, but not limited to, KVSB being treated as the 'acquired' company for financial reporting purposes in the Business Combination, the cash and cash equivalents of Nextdoor on the Closing Date and the number of shares of KVSB Class A common stock that are redeemed in connection with the Business Combination. Accordingly, such pro forma financial information may not be indicative of New Nextdoor's future operating or financial performance and New Nextdoor's actual financial condition and operating results may vary materially from New Nextdoor's pro forma results of operations and balance sheet contained elsewhere in this proxy statement/prospectus, including as a result of such assumptions not being accurate. See the section entitled 'Unaudited Pro Forma Condensed Combined Financial Information.'

We have a specified maximum redemption threshold. This redemption threshold may make it more difficult for us to complete the Business Combination as contemplated.

The Merger Agreement provides that Nextdoor's obligation to consummate the Business Combination is conditioned on, among other things, that as of the Closing, the amount of cash available in the trust account, (x) the amount required to satisfy KVSB's obligations to its stockholders (if any) that exercise their rights to redeem their public shares pursuant to the Existing Organizational Documents and (y) all accrued and unpaid Transaction Expenses of Nextdoor and KVSB, plus the PIPE Investment Amount actually received by KVSB prior to or substantially concurrently with Closing plus the aggregate amount of cash that has been funded to and remains with KVSB pursuant to the Forward Purchase Agreement, as applicable, shall be equal to or greater than $400.0 million.

The Minimum Cash Condition is for the sole benefit of Nextdoor. If such condition is not met, and such condition is not or cannot be waived under the terms of the Merger Agreement, then the Merger Agreement could terminate and the proposed Business Combination may not be consummated. There can be no assurance that Nextdoor could and would waive the Minimum Cash Condition. In addition, pursuant to the Existing Organizational Documents, in no event will KVSB redeem public shares in an amount that would cause New Nextdoor's net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) of the Exchange Act) to be less than $5,000,001.

If such conditions are waived and the Business Combination is consummated with less than the Minimum Available Cash Amount in the trust account, the cash held by New Nextdoor and its subsidiaries (including Nextdoor) in the aggregate, after the Closing may not be sufficient to allow us to operate and meet our financial obligations as they become due. The additional exercise of redemption rights with respect to a large number of our public stockholders may make us unable to take such actions as may be desirable in order to optimize the capital structure of New Nextdoor after consummation of the Business Combination and we may not be able to raise additional financing necessary to fund our expenses and liabilities after the Closing. Any such event in the future may negatively impact the analysis regarding our ability to continue as a going concern at such time.

The Sponsor may elect to purchase shares from public stockholders prior to the consummation of the Business Combination, which may influence the vote on the Business Combination and reduce the public 'float' of our securities.

to redeem, or indicate an intention to redeem, public shares, (ii) execute agreements to purchase such shares from such investors in the future, or (iii) enter into transactions with such investors and others to provide them with incentives to acquire public shares, vote their public shares in favor of the Condition Precedent Proposals or not redeem their public shares. Such a purchase may include a contractual acknowledgement that such stockholder, although still the record holder of KVSB's shares, is no longer the beneficial owner thereof and therefore agrees not to exercise its redemption rights. In the event that the Sponsor, the existing stockholders of Nextdoor or our or their respective directors, officers, advisors, or respective affiliates purchase shares in privately negotiated transactions from public stockholders who have already elected to exercise their redemption rights, such selling stockholders would be required to revoke their prior elections to redeem their shares. The purpose of such share purchases and other transactions would be to increase the likelihood of (1) satisfaction of the requirement that the BCA Proposal, the Charter Proposal, the Equity Incentive Plan Proposal, the ESPP Proposal and the Adjournment Proposal by a requisite vote of our stockholders, (2) satisfaction of the Minimum Cash Condition, (3) otherwise limiting the number of public shares electing to redeem and (4) KVSB's net tangible assets (as determined in accordance with Rule 3a51(g)(1) of the Exchange Act) being at least $5,000,001.

Entering into any such arrangements may have a depressive effect on the shares of KVSB common stock (e.g., by giving an investor or holder the ability to effectively purchase shares at a price lower than market, such investor or holder may therefore become more likely to sell the shares he or she owns, either at or prior to the Business Combination). If such transactions are effected, the consequence could be to cause the Business Combination to be consummated in circumstances where such consummation could not otherwise occur. Purchases of shares by the persons described above would allow them to exert more influence over the approval of the proposals to be presented at the special meeting and would likely increase the chances that such proposals would be approved. In addition, if such purchases are made, the public 'float' of our securities and the number of beneficial holders of our securities may be reduced, possibly making it difficult to maintain or obtain the quotation, listing or trading of our securities on a national securities exchange.

If third parties bring claims against us, the proceeds held in the trust account could be reduced and the per share redemption amount received by stockholders may be less than $10.00 per share (which was the offering price per unit in our initial public offering).

Our placing of funds in the trust account may not protect those funds from third-party claims against us. Although we will seek to have all vendors, service providers (other than our independent auditors), prospective target businesses and other entities with which we do business execute agreements with us waiving any right, title, interest or claim of any kind in or to any monies held in the trust account, there is no guarantee that they will execute such agreements or even if they execute such agreements that they would be prevented from bringing claims against the trust account, including, but not limited to, fraudulent inducement, breach of fiduciary responsibility or other similar claims, as well as claims challenging the enforceability of the waiver, in each case in order to gain advantage with respect to a claim against our assets, including the funds held in the trust account. If any third party refuses to execute an agreement waiving such claims to the monies held in the trust account, our management will perform an analysis of the alternatives available to it and will enter into an agreement with a third party that has not executed a waiver only if management believes that such third party's engagement would be significantly more beneficial to us than any alternative.

Examples of possible instances where we may engage a third party that refuses to execute a waiver include the engagement of a third party consultant whose particular expertise or skills are believed by management to be significantly superior to those of other consultants that would agree to execute a waiver or in cases where management is unable to find a service provider willing to execute a waiver. In addition, there is no guarantee that such entities will agree to waive any claims they may have in the future as a result of, or arising out of, any negotiations, contracts or agreements with us and will not seek recourse against the trust account for any reason. Upon redemption of our public shares, if we have not completed our business combination within the required time period, or upon the exercise of a redemption right in connection with our business combination, we will be required to provide for payment of claims of creditors that were not waived that may be brought against us within the 10 years following redemption.

Accordingly, the per share redemption amount received by public stockholders could be less than the $10.00 per public share initially held in the trust account, due to claims of such creditors.

The Sponsor has agreed that it will be liable to us if and to the extent any claims by a third party (other than our independent auditors) for services rendered or products sold to us, or a prospective target business with which we have discussed entering into a transaction agreement, reduce the amount of funds in the trust account to below the lesser of (1) $10.00 per public share or (2) the actual amount per public share held in the trust account as of the date of the liquidation of the trust account if less than $10.00 per share due to reductions in the value of the trust assets, in each case net of the interest which may be withdrawn to pay taxes, if any, provided that such liability will not apply to any claims by a third party or prospective target business that executed a waiver of any and all rights to seek access to the trust account nor will it apply to any claims under our indemnity of the underwriters of this offering against certain liabilities, including liabilities under the Securities Act. Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. We have not independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and believe that the Sponsor's only assets are securities of our company. The Sponsor may not have sufficient funds available to satisfy those obligations. We have not asked the Sponsor to reserve for such obligations, and therefore, no funds are currently set aside to cover any such obligations. As a result, if any such claims were successfully made against the trust account, the funds available for our business combination and redemptions could be reduced to less than $10.00 per public share. In such event, we may not be able to complete our business combination, and you would receive such lesser amount per share in connection with any redemption of your public shares. None of our directors or officers will indemnify us for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

If, after we distribute the proceeds in the trust account to our public stockholders, we file a winding-up or bankruptcy petition or an involuntary winding-up or bankruptcy petition is filed against us that is not dismissed, a bankruptcy court may seek to recover such proceeds, and we and our board of directors may be exposed to claims of punitive damages.

If, after we distribute the proceeds in the trust account to our public stockholders, we file a winding-up or bankruptcy petition or an involuntary winding-up or bankruptcy petition is filed against us that is not dismissed, any distributions received by stockholders could be viewed under applicable debtor/creditor and/or insolvency laws as a voidable preference. As a result, a liquidator could seek to recover all amounts received by our stockholders. In addition, our board of directors may be viewed as having breached its fiduciary duty to our creditors or having acted in bad faith, thereby exposing it and us to claims of punitive damages, by paying public stockholders from the trust account prior to addressing the claims of creditors. We cannot assure you that claims will not be brought against us for these reasons.

If, before distributing the proceeds in the trust account to our public stockholders, we file a winding-up or bankruptcy petition or an involuntary winding-up or bankruptcy petition is filed against us that is not dismissed, the claims of creditors in such proceeding may have priority over the claims of our stockholders and the per share amount that would otherwise be received by our stockholders in connection with our liquidation may be reduced.

If, before distributing the proceeds in the trust account to our public stockholders, we file a winding-up or bankruptcy petition or an involuntary winding-up or bankruptcy petition is filed against us that is not dismissed, the proceeds held in the trust account could be subject to applicable insolvency law, and may be included in our liquidation estate and subject to the claims of third parties with priority over the claims of our stockholders. To the extent any liquidation claims deplete the trust account, the per share amount that would otherwise be received by our stockholders in connection with our liquidation would be reduced.

Our stockholders may be held liable for claims by third parties against us to the extent of distributions received by them upon redemption of their shares.

If we are forced to enter into an insolvent liquidation, any distributions received by stockholders could be viewed as an unlawful payment if it was proved that immediately following the date on which the distribution was made, we were unable to pay our debts as they fall due in the ordinary course of business. As a result, a liquidator

could seek to recover all amounts received by our stockholders. Furthermore, our directors may be viewed as having breached their fiduciary duties to us or our creditors or may have acted in bad faith, and thereby exposing themselves and our company to claims, by paying public stockholders from the trust account prior to addressing the claims of creditors. We cannot assure you that claims will not be brought against us for these reasons.

Past performance by any member or members of our management team or any of their respective affiliates may not be indicative of future performance of an investment in Nextdoor or New Nextdoor.

Past performance by any member or members of our management team or any of their respective affiliates, is not a guarantee of success with respect to the Business Combination. You should not rely on the historical record of any member or members of our management team, any of their respective affiliates or any of the foregoing's related investment's performance, as indicative of the future performance of an investment in Nextdoor or New Nextdoor or the returns Nextdoor or New Nextdoor will, or is likely to, generate going forward.

The public stockholders will experience immediate dilution as a consequence of the issuance of New Nextdoor common stock as consideration in the Business Combination and the PIPE Investment and due to future issuances pursuant to the Equity Incentive Plan. Having a minority share position may reduce the influence that our current stockholders have on the management of New Nextdoor.

It is anticipated that, following the Business Combination, (1) KVSB's public stockholders are expected to own approximately 10.9% of the outstanding New Nextdoor common stock (and 1.3% of the voting power of the New Nextdoor common stock), (2) Nextdoor Stockholders (without taking into account any public shares held by Nextdoor Stockholders prior to the consummation of the Business Combination) are expected to own approximately 79.0% of the outstanding New Nextdoor common stock (and 94.3% of the voting power of the New Nextdoor common stock), (3) the Sponsor and related parties expected to own approximately 3.0% of the outstanding New Nextdoor common stock (and 3.6% of the voting power of the New Nextdoor common stock) and (4) the PIPE Investors are expected to own approximately 7.1% of the outstanding New Nextdoor common stock (and 0.8% of the voting power of the New Nextdoor common stock). These percentages assumes (i) that no public stockholders exercise their redemption rights in connection with the Business Combination, (ii) the exclusion of (a) an estimated 62,168,894 shares of New Nextdoor Class B common stock reserved for potential future issuance upon the exercise of New Nextdoor Options and settlement of New Nextdoor RSUs or New Nextdoor Restricted Stock Awards and (b) an estimated 180,503 shares of New Nextdoor Class B common stock related to certain entitlements to receive Nextdoor common stock pursuant to the terms of the Pixel Labs Merger Agreement, which were canceled and converted into the right to receive New Nextdoor Class B common stock equal to the Exchange Ratio multiplied by the number of Nextdoor common stock held by such holder immediately prior to the Effective Time, (iii) the inclusion of New Nextdoor Class B common stock issued as the Aggregate Merger Consideration pursuant to the Merger Agreement, which in the aggregate equals 302,532,879 shares of New Nextdoor Class B common stock, (iv) New Nextdoor issues 27,000,000 shares of New Nextdoor Class A common stock to the PIPE Investors pursuant to the PIPE Investment, (v) New Nextdoor issues zero shares of New Nextdoor common stock to Sponsor (together with any permitted transferees under the Forward Purchase Agreement) pursuant to the Forward Purchase Agreement, (vi) the conversion and exchange of all outstanding KVSB Class B common stock shares into an aggregate of 7,347,249 shares of New Nextdoor Class B common stock and (vii) the conversion of all outstanding KVSB Class K common stock shares into an aggregate of 3,061,354 shares of New Nextdoor Class B common stock. If the actual facts are different from these assumptions, the percentage ownership retained by the Company's existing stockholders in the combined company will be different.

The Third-Party PIPE Investors have agreed to purchase 21,750,000 shares of New Nextdoor Class A common stock, at $10.00 per share, for approximately $217.50 million of gross proceeds. The Sponsor Related PIPE Investors have agreed to purchase 750,000 shares of New Nextdoor Class A common stock, at $10.00 per share, for approximately $7.5 million of gross proceeds. The Nextdoor PIPE Investors have agreed to purchase 4,500,000 shares of New Nextdoor Class A common stock, at $10.00 per share, for approximately $45.0 million of gross proceeds.

If the actual facts are different from these assumptions, the percentage ownership retained by KVSB's existing stockholders in the combined company will be different.

In addition, Nextdoor employees, members of the board of directors, and other service providers are expected to be granted, after the Business Combination, equity awards under the Equity Incentive Plan and purchase rights under the ESPP. You will experience additional dilution when those equity awards and purchase rights become vested and settled or exercisable, as applicable, for shares of New Nextdoor Class A common stock.

The issuance of additional New Nextdoor common stock will significantly dilute the equity interests of existing holders of KVSB securities and may adversely affect prevailing market prices for our public shares.

may not list New Nextdoor's securities on its exchange, which could limit investors' ability to make transactions in New Nextdoor's securities and subject New Nextdoor to additional trading restrictions.

We will apply to have New Nextdoor's securities listed on upon consummation of the Business Combination. In order to continue to maintain the listing of our securities on Nasdaq, we will be required to demonstrate compliance with 's initial listing requirements, which are more rigorous than 's continued listing requirements.

We cannot assure you that we will be able to meet all of the initial listing requirements of . Even if New Nextdoor's securities are listed on , New Nextdoor may be unable to maintain the listing of its securities in the future.

If New Nextdoor fails to meet the initial listing requirements and does not list its securities on its exchange, Nextdoor would not be required to consummate the Business Combination. In the event that Nextdoor elected to waive this condition, and the Business Combination was consummated without New Nextdoor's securities being listed on or on another national securities exchange, New Nextdoor could face significant material adverse consequences, including:

•a limited availability of market quotations for New Nextdoor's securities;

•reduced liquidity for New Nextdoor's securities;

•a determination that New Nextdoor common stock is a 'penny stock' which will require brokers trading in New Nextdoor common stock to adhere to more stringent rules and possibly result in a reduced level of trading activity in the secondary trading market for New Nextdoor's securities;

•a limited amount of news and analyst coverage; and

•a decreased ability to issue additional securities or obtain additional financing in the future.

The National Securities Markets Improvement Act of 1996, which is a federal statute, prevents or preempts the states from regulating the sale of certain securities, which are referred to as 'covered securities.' If New Nextdoor's securities were not listed on , such securities would not qualify as covered securities and we would be subject to regulation in each state in which we offer our securities because states are not preempted from regulating the sale of securities that are not covered securities.

KVSB's and Nextdoor's ability to consummate the Business Combination, and the operations of New Nextdoor following the Business Combination, may be materially adversely affected by the recent coronavirus ('COVID-19') pandemic.

The COVID-19 outbreak has adversely affected, and other events (such as terrorist attacks, natural disasters or a significant outbreak of other infectious diseases or public health crises) could adversely affect, economies and financial markets worldwide, business operations and the conduct of commerce generally, and the business of Nextdoor or New Nextdoor following the Business Combination could be adversely affected. The extent of such impact will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of COVID-19 and the actions to contain COVID-19 or treat its impact, among others.

The outbreak of COVID-19 may also have the effect of heightening many of the other risks described in this 'Risk Factors' section, such as those related to the market for our securities.

Additional Risks Related to Ownership of New Nextdoor Class A Common Stock Following the Business Combination and New Nextdoor Operating as a Public Company

The dual class structure of New Nextdoor's common stock may adversely affect the trading market for its Class A common stock following the closing of the transaction.

S&P Dow Jones and FTSE Russell limit their eligibility criteria for inclusion of shares of public companies on certain indices, including the S&P 500, namely, to exclude companies with multiple classes of shares of common stock from being added to such indices. In addition, several shareholder advisory firms have announced their opposition to the use of multiple class structures. As a result, the dual class structure of New Nextdoor's common stock may prevent the inclusion of New Nextdoor's Class A common stock in such indices and may cause shareholder advisory firms to publish negative commentary about New Nextdoor's corporate governance practices or otherwise seek to cause New Nextdoor to change its capital structure. Any such exclusion from indices could result in a less active trading market for New Nextdoor's Class A common stock. Any actions or publications by shareholder advisory firms critical of Nextdoor's corporate governance practices or capital structure could also adversely affect the value of New Nextdoor's Class A common stock.

The dual class structure of New Nextdoor's common stock will have the effect of concentrating voting power with New Nextdoor's management and other existing stockholders, which will limit your ability to influence the outcome of important transactions, including a change in control.

New Nextdoor's Class B common stock has 10 votes per share and its Class A common stock has one vote per share. Following the Business Combination, New Nextdoor stockholders who hold shares of Class B common stock, including certain of New Nextdoor's executive officers, employees, and directors and their affiliates and other existing stockholders, including the Sponsor, together will hold a substantial majority of the voting power of New Nextdoor's outstanding capital stock. Because of the 10-to-1 voting ratio between New Nextdoor's Class B and Class A common stock, the holders of New Nextdoor's Class B common stock will, following the Business Combination, collectively control a majority of the combined voting power of common stock and therefore will be able to control all matters submitted to New Nextdoor's stockholders for approval so long as the shares of Class B common stock represent at least 9.1% of all outstanding shares of its Class A and Class B common stock. This concentrated control will limit or preclude your ability to influence the outcome of important corporate matters, including a change in control, for the foreseeable future.

Following the Business Combination, transfers by holders of Class B common stock will generally result in those shares converting to Class A common stock, subject to limited exceptions, such as certain transfers effected for estate planning or charitable purposes. The conversion of Class B common stock to Class A common stock will have the effect, over time, of increasing the relative voting power of those holders of Class B common stock who retain their shares in the long term.

The price of New Nextdoor Class A common stock may be volatile.

Upon consummation of the Business Combination, the price of New Nextdoor common stock, may fluctuate due to a variety of factors, including:

•actual or anticipated fluctuations in our user growth, retention, engagement, revenue, or other operating results;

•developments involving New Nextdoor's competitors;

•variations between our actual operating results and the expectations of securities analysts, investors, and the financial community;

•actual or anticipated fluctuations in New Nextdoor's quarterly or annual operating results;

•any forward-looking financial or operating information we may provide to the public or securities analysts, any changes in this information, or our failure to meet expectations based on this information;

•publication of research reports by securities analysts about New Nextdoor or its competitors or its industry;

•the public's reaction to New Nextdoor's press releases, its other public announcements and its filings with the SEC;

•additional shares of our common stock being sold into the market by us or our existing stockholders, or the anticipation of such sales, or if existing stockholders subject to a lock-up sell shares into the market when applicable 'lock-up' periods end;

•additions and departures of key personnel;

•commencement of, or involvement in, litigation involving the combined company;

•changes in its capital structure, such as future issuances of securities or the incurrence of additional debt;

•the volume of shares of New Nextdoor common stock available for public sale;

•announcements by us or our competitors of significant products or features, technical innovations, acquisitions, strategic partnerships, joint ventures, or capital commitments;

•announcements by us or estimates by third parties of actual or anticipated changes in the size of our user base or the level of user engagement;

•changes in operating performance and stock market valuations of technology companies in our industry, including our partners and competitors;

•price and volume fluctuations in the overall stock market, including as a result of trends in the economy as a whole;

•developments in new legislation and pending lawsuits or regulatory actions, including interim or final rulings by judicial or regulatory bodies; and

•other events or factors, including those resulting from effects of the COVID-19 outbreak, recessions, interest rates, local and national elections, international currency fluctuations, corruption, political instability and acts of war or terrorism.

In addition, extreme price and volume fluctuations in the stock markets have affected and continue to affect many technology companies' stock prices. Often, their stock prices have fluctuated in ways unrelated or disproportionate to the companies' operating performance. In the past, stockholders have filed securities class action litigation following periods of market volatility. If we were to become involved in securities litigation, it could subject us to substantial costs, divert resources and the attention of management from our business, and seriously harm our business.

New Nextdoor will have broad discretion in how we may use the net proceeds in connection with the Business Combination, and we may not use them effectively.

We cannot specify with any certainty the particular uses of the net proceeds that we will receive in connection with the Business Combination. Our management will have broad discretion in applying the net proceeds we receive in connection with the Business Combination. We may use the net proceeds for general corporate purposes, including working capital, operating expenses, and capital expenditures. We may use a portion of the net proceeds to

acquire complementary businesses, products, services, or technologies. We may also spend or invest these proceeds in a way with which our stockholders disagree. If our management fails to use these funds effectively, our business could be seriously harmed. Pending their use, the net proceeds that we receive in connection with the Business Combination may be invested in a way that does not produce income or that loses value.

New Nextdoor does not intend to pay cash dividends for the foreseeable future.

Following the Business Combination, New Nextdoor currently intends to retain its future earnings, if any, to finance the further development and expansion of its business and does not intend to pay cash dividends in the foreseeable future. Any future determination to pay dividends will be at the discretion of New Nextdoor's board of directors and will depend on its financial condition, results of operations, capital requirements, restrictions contained in future agreements and financing instruments, business prospects and such other factors as its board of directors deems relevant. As a result, you may only receive a return on your investment in our Class A common stock if the market price of our Class A common stock increases.

Because Nextdoor is going public through a business combination instead of an initial public offering, no underwriter has assumed risk in connection with the business combination or conducted due diligence of Nextdoor's business, operations or financial condition, including review of the disclosure in this proxy statement/prospectus.

Nextdoor is going public through a business combination. The business combination transaction is not an underwritten initial public offering and, therefore, underwriters have not assumed risk in connection with the business combination. Section 11 of the Securities Act ('Section 11') imposes liability on parties, including underwriters, involved in a securities offering if the registration statement contains a materially false statement or material omission. To effectively establish a due diligence defense against a cause of action brought pursuant to Section 11, a defendant, including an underwriter, carries the burden of proof to demonstrate that, after reasonable investigation, it believed that the statements in the registration statement were true and that there was no omission to state a material fact required to be stated therein or necessary to make the statements therein not misleadingmaterial omissions. In order to meet this burden of proof, underwriters in a registered offering typically conduct extensive due diligence of the registrant, including reviewing the registrant's disclosure in the registration statement. Such due diligence may include calls with the issuer's management, review of material agreements, and background checks on key personnel, among other investigations.

Because Nextdoor intends to become publicly traded through a business combination with a special purpose acquisition company rather than through an underwritten offering of its common stock, no underwriter is involved in the transaction. As a result, no underwriter has conducted diligence on Nextdoor in order to establish a due diligence defense with respect to the disclosure presented in this proxy statement/prospectus. If such investigation had occurred, certain information in this proxy statement/prospectus may have been presented in a different manner or additional information may have been presented at the request of such underwriter. Moreover, no underwriter will be subject to liability to investors in connection with misstatements in this proxy statement/prospectus.

If analysts do not publish research about New Nextdoor's business or if they publish inaccurate or unfavorable research, New Nextdoor's stock price and trading volume could decline.

The trading market for New Nextdoor common stock will depend in part on the research and reports that analysts publish about its business. New Nextdoor does not have any control over these analysts. If one or more of the analysts who cover New Nextdoor downgrade its common stock or publish inaccurate or unfavorable research about its business, the price of its common stock would likely decline. If few analysts cover New Nextdoor, demand for its common stock could decrease and its common stock price and trading volume may decline. Similar results may occur if one or more of these analysts stop covering New Nextdoor in the future or fail to publish reports on it regularly.

New Nextdoor may be subject to securities litigation, which is expensive and could divert management attention.

The market price of New Nextdoor common stock may be volatile and, in the past, companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. New

Nextdoor may be the target of this type of litigation in the future. Securities litigation against New Nextdoor could result in substantial costs and divert management's attention from other business concerns, which could seriously harm its business.

Future resales of common stock after the consummation of the Business Combination may cause the market price of New Nextdoor's securities to drop significantly, even if New Nextdoor's business is doing well.

After the consummation of the Business Combination and subject to certain exceptions, the Sponsor and the Nextdoor Stockholders will be contractually restricted from selling or transferring any of its shares of common stock (not including the shares of New Nextdoor Class A common stock issued in the PIPE Investment pursuant to the terms of the Subscription Agreements or purchased in the public market) (the 'Lock-up Shares') for certain periods of time. Under the Proposed Bylaws, and subject to certain customary exceptions, such lockup restrictions applicable to all the Nextdoor Stockholders' Lock-up Shares begin at the Closing and end on the date that is 180 days following the Closing. Pursuant to the Sponsor lock-up agreement, and subject to certain customary exceptions, such lockup restrictions applicable to the Sponsor Lock-up Shares begin at the Closing and end on the date that is one year following the Closing.

Following the expiration of each lockup, the applicable stockholders will not be restricted from selling shares of New Nextdoor common stock held by them, other than by applicable securities laws. Additionally, the Third-Party PIPE Investors will not be restricted from selling any of their shares of our Class A common stock following the closing of the Business Combination, other than by applicable securities laws. As such, sales of a substantial number of shares of New Nextdoor Class A common stock in the public market could occur at any time. These sales, or the perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market price of New Nextdoor Class A common stock. Upon completion of the Business Combination, the Sponsor and related parties and the Nextdoor Stockholders will collectively own approximately 82.0% of the outstanding shares of New Nextdoor common stock, assuming (i) that no public stockholders exercise their redemption rights in connection with the Business Combination, (ii) the exclusion of (a) an estimated 62,168,894 shares of New Nextdoor Class B common stock reserved for potential future issuance upon the exercise of New Nextdoor Options and settlement of New Nextdoor RSUs or New Nextdoor Restricted Stock Awards and (b) an estimated 180,503 shares of New Nextdoor Class B common stock related to certain entitlements to receive Nextdoor common stock pursuant to the terms of the Pixel Labs Merger Agreement, which were canceled and converted into the right to receive New Nextdoor Class B common stock equal to the Exchange Ratio multiplied by the number of Nextdoor common stock held by such holder immediately prior to the Effective Time, (iii) the inclusion of New Nextdoor Class B common stock issued as the Aggregate Merger Consideration pursuant to the Merger Agreement, which in the aggregate equals 302,532,879 shares of New Nextdoor Class B common stock, (iv) New Nextdoor issues 27,000,000 shares of New Nextdoor Class A common stock to the PIPE Investors pursuant to the PIPE Investment, (v) New Nextdoor issues zero shares of New Nextdoor common stock to Sponsor (together with any permitted transferees under the Forward Purchase Agreement) pursuant to the Forward Purchase Agreement, (vi) the conversion and exchange of all outstanding KVSB Class B common stock shares into an aggregate of 7,347,249 shares of New Nextdoor Class B common stock and (vii) the conversion of all outstanding KVSB Class K common stock shares into an aggregate of 3,061,354 shares of New Nextdoor Class B common stock. The ownership of the Sponsor and its related parties and the Nextdoor Stockholders would rise to 87.8% of the outstanding shares of New Nextdoor common stock if, in addition to the assumptions (i) through (vii) above, 24,932,638 public shares are redeemed in connection with the Business Combination.

As restrictions on resale end and registration statements (filed after the Closing to provide for the resale of such shares from time to time) are available for use, the sale or possibility of sale of these shares could have the effect of increasing the volatility in New Nextdoor's share price or the market price of New Nextdoor common stock could decline if the holders of currently restricted shares sell them or are perceived by the market as intending to sell them.

Compliance obligations under the Sarbanes-Oxley Act may make it more difficult for us to effectuate the Business Combination, require substantial financial and management resources and increase the time and costs of completing a business combination.

The fact that we are a blank check company makes compliance with the requirements of the Sarbanes-Oxley Act particularly burdensome on us as compared to other public companies because Nextdoor is not currently subject to Section 404 of the Sarbanes-Oxley Act. The standards required for a public company under Section 404 of the Sarbanes-Oxley Act are significantly more stringent than those required of Nextdoor as privately held companies. Management may not be able to effectively and timely implement controls and procedures that adequately respond to the increased regulatory compliance and reporting requirements that will be applicable to New Nextdoor after the Business Combination. If we are not able to implement the requirements of Section 404, including any additional requirements once we are no longer an emerging growth company, in a timely manner or with adequate compliance, we may not be able to assess whether its internal controls over financial reporting are effective, which may subject us to adverse regulatory consequences and could harm investor confidence and the market price of New Nextdoor common stock. Additionally, once we are no longer an emerging growth company, we will be required to comply with the independent registered public accounting firm attestation requirement on our internal control over financial reporting.

We are an emerging growth company and a smaller reporting company within the meaning of the Securities Act, and if we take advantage of certain exemptions from disclosure requirements available to emerging growth companies or smaller reporting companies, this could make our securities less attractive to investors and may make it more difficult to compare our performance with other public companies.

We are an 'emerging growth company' within the meaning of the Securities Act, as modified by the JOBS Act, and we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. As a result, our stockholders may not have access to certain information they may deem important. We could be an emerging growth company for up to five years, although circumstances could cause us to lose that status earlier, including if the market value of our shares of common stock held by non-affiliates exceeds $700 million as of the end of any second quarter of a fiscal year, in which case we would no longer be an emerging growth company as of the end of such fiscal year. We cannot predict whether investors will find our securities less attractive because we will rely on these exemptions. If some investors find our securities less attractive as a result of our reliance on these exemptions, the trading prices of our securities may be lower than they otherwise would be, there may be a less active trading market for our securities and the trading prices of our securities may be more volatile.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. We have elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make it difficult or impossible to compare our financial results with the financial results of another public company that is either not an emerging growth company or is an emerging growth company that has chosen not to take advantage of the extended transition period exemptions because of the potential differences in accounting standards used.

Additionally, we are a 'smaller reporting company' as defined in Item 10(f)(1) of Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements. We will remain a smaller reporting company until the last

day of the fiscal year in which (1) the market value of our shares of common stock held by non-affiliates equals or exceeds $250 million as of the end of that year's second fiscal quarter, and (2) our annual revenues equaled or exceeded $100 million during such completed fiscal year or the market value of our shares of common stock held by non-affiliates equals or exceeds $700 million as of the end of that year's second fiscal quarter. To the extent we take advantage of such reduced disclosure obligations, it may also make comparison of our financial statements with other public companies difficult or impossible.

Provisions in our charter documents following the Business Combination and under Delaware law, including anti-takeover provisions, could make an acquisition of us, which may be beneficial to our stockholders, more difficult and may limit attempts by our stockholders to replace or remove our current management.

Provisions in our restated certificate of incorporation and restated bylaws following the Business Combination, including anti-takeover provisions, may have the effect of delaying or preventing a merger, acquisition or other change of control of the company that our stockholders may consider favorable. In addition, because our board of directors is responsible for appointing the members of our management team, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors. Among other things, our restated certificate of incorporation and restated bylaws include provisions that:

•provide that our board of directors is classified into three classes of directors with staggered three-year terms;

•permit our board of directors to establish the number of directors and fill any vacancies and newly created directorships;

•require super-majority voting to amend some provisions in our restated certificate of incorporation and restated bylaws;

•authorize the issuance of 'blank check' preferred stock that our board of directors could use to implement a stockholder rights plan;

•provide that only our chairperson of the board of directors, our chief executive officer, the lead independent director or a majority of our board of directors will be authorized to call a special meeting of stockholders;

•eliminate the ability of our stockholders to call special meetings of stockholders;

•do not provide for cumulative voting;

•provide that directors may only be removed 'for cause' and only with the approval of two-thirds of our stockholders;

•provide for a dual class common stock structure in which holders of our Class B common stock may have the ability to control the outcome of matters requiring stockholder approval, even if they own significantly less than a majority of the outstanding shares of our common stock, including the election of directors and other significant corporate transactions, such as a merger or other sale of our company or its assets;

•prohibit stockholder action by written consent, which requires all stockholder actions to be taken at a meeting of our stockholders;

•provide that our board of directors is expressly authorized to make, alter, or repeal our bylaws; and

•establish advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted upon by stockholders at annual stockholder meetings.

Moreover, Section 203 of the DGCL may discourage, delay, or prevent a change in control of our company. Section 203 imposes certain restrictions on mergers, business combinations, and other transactions between us and holders of 15% or more of our common stock.

Our restated certificate of incorporation following the Business Combination will contain exclusive forum provisions for certain claims, which may limit our stockholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees.

Our restated certificate of incorporation following the Business Combination will provide that the Court of Chancery of the State of Delaware, to the fullest extent permitted by law, will be the exclusive forum for any derivative action or proceeding brought on our behalf, any action asserting a breach of fiduciary duty, any action asserting a claim against us arising pursuant to the DGCL, our restated certificate of incorporation, or our restated bylaws, or any action asserting a claim against us that is governed by the internal affairs doctrine.

Moreover, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all claims brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. Our restated certificate of incorporation provides that the federal district courts of the United States will, to the fullest extent permitted by law, be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act, or Federal Forum Provision. Our decision to adopt a Federal Forum Provision followed a decision by the Supreme Court of the State of Delaware holding that such provisions are facially valid under Delaware law. While there can be no assurance that federal or state courts will follow the holding of the Delaware Supreme Court or determine that the Federal Forum Provision should be enforced in a particular case, application of the Federal Forum Provision means that suits brought by our stockholders to enforce any duty or liability created by the Securities Act must be brought in federal court and cannot be brought in state court.

Section 27 of the Exchange Act creates exclusive federal jurisdiction over all claims brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. In addition, the Federal Forum Provision applies to suits brought to enforce any duty or liability created by the Exchange Act. Accordingly, actions by our stockholders to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder must be brought in federal court.

Our stockholders will not be deemed to have waived our compliance with the federal securities laws and the regulations promulgated thereunder.

Any person or entity purchasing or otherwise acquiring or holding any interest in any of our securities shall be deemed to have notice of and consented to our exclusive forum provisions, including the Federal Forum Provision. These provisions may limit a stockholders' ability to bring a claim in a judicial forum of their choosing for disputes with us or our directors, officers, or employees, which may discourage lawsuits against us and our directors, officers, and employees. Alternatively, if a court were to find the choice of forum provision contained in our restated certificate of incorporation or restated bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, financial condition, and operating results.

•a proposal to adjourn the special meeting to a later date or dates, if necessary, to permit further solicitation and vote of proxies in the event that there are insufficient votes for the approval of one or more proposals at the special meeting (the 'Adjournment Proposal').

Each of the Condition Precedent Proposals is cross-conditioned on the approval of each other. The Advisory Charter Amendment Proposals and the Adjournment Proposal are not conditioned upon the approval of any other proposal set forth in this proxy statement/prospectus.

Recommendation of KVSB Board of Directors

The KVSB Board believes that the BCA Proposal and the other proposals to be presented at the special meeting are in the best interest of KVSB's stockholders and unanimously recommends that its stockholders vote 'FOR' the BCA Proposal, 'FOR' the Charter Proposal, 'FOR' each of the Advisory Charter Amendment Proposals, 'FOR' the Stock Issuance Proposal, 'FOR' the Equity Incentive Plan Proposal, 'FOR' the ESPP Proposal and 'FOR' the Adjournment Proposal, in each case, if presented at the special meeting.

Record Date; Who is Entitled to Vote

KVSB stockholders will be entitled to vote or direct votes to be cast at the special meeting if they owned common stock at the close of business on , 2021, which is the 'record date' for the special meeting. Stockholders will have one vote for each share of KVSB common stock owned at the close of business on the record date. If your shares are held in 'street name' or are in a margin or similar account, you should contact your broker to ensure that votes related to the shares you beneficially own are properly counted. As of the close of business on the record date, there were common stock issued and outstanding, of which were issued and outstanding public shares.

The Sponsor and each director and officer of KVSB have agreed to, among other things, vote in favor of the Merger Agreement and the transactions contemplated thereby, in each case, subject to the terms and conditions contemplated by the Sponsor Support Agreement, and waive their redemption rights in connection with the consummation of the Business Combination with respect to any common stock held by them, and vote for any amendments to the governing documents as are necessary to convert or reclassify and/or exchange all shares of KVSB Class K common stock and KVSB Class B common stock into an aggregate of 10,408,603 shares of New Nextdoor Class B common stock at the Closing and all of KVSB's Class A common stock into KVSB Class B common stock, and waive any adjustments to the conversion ratio that would otherwise have been applicable for a conversion into any amount in excess of such amount. The common stock held by the Sponsor will be excluded from the pro rata calculation used to determine the per-share redemption price. As of the date of this proxy statement/prospectus, the Sponsor and KVSB's independent directors collectively own issued and outstanding shares of KVSB common stock representing 16.9% of the outstanding voting power on an as-converted basis, and 12.8% of the outstanding voting power on a per actual share basis.

Quorum

A quorum of KVSB stockholders is necessary to hold valid meetings. A quorum will be present at the special meeting if the holders of outstanding KVSB common stock representing a majority of the voting power of all outstanding shares entitled to vote at the special meeting are represented in person or by proxy at the special meeting. As of the record date for the special meeting, an aggregate of shares of KVSB Class A common stock and KVSB Class B common stock (on an as-converted basis) would be required to achieve a quorum.

Abstentions and Broker Non-Votes

Proxies that are marked 'abstain' and proxies relating to 'street name' shares that are returned to KVSB but marked by brokers as 'not voted' will be treated as shares present for purposes of determining the presence of a quorum on all matters, but they will not be treated as shares voted on the matter. Under the rules of various national and regional securities exchanges, your broker, bank, or nominee cannot vote your shares with respect to non-discretionary matters unless you provide instructions on how to vote in accordance with the information and procedures provided to you by your broker, bank, or nominee. We believe all the proposals presented to the

stockholders will be considered non-discretionary and therefore your broker, bank, or nominee cannot vote your shares without your instruction.

An abstention will be counted towards the quorum requirement but will not count as a vote cast at the special meeting. A broker non-vote will not be counted towards the quorum requirement, as we believe all proposals presented to the stockholders will be considered non-discretionary, or count as a vote cast at the special meeting.

Vote Required for Approval

The approval of the BCA Proposal requires the affirmative vote of holders of a majority of the shares of KVSB Class A common stock and KVSB Class B common stock that are voted at the special meeting. Assuming the minimum number of shares of KVSB Class A common stock and KVSB Class B common stock representing a quorum are present and voted, and assuming that all shares of KVSB Class B common stock and all private placement shares are present and voted in favor of the BCA Proposal, a total of 5,809,088 public shares would need to be voted in favor of the BCA Proposal. The BCA Proposal is conditioned on the approval of each of the Condition Precedent Proposals. Therefore, if any of the Condition Precedent Proposals is not approved, the BCA Proposal will have no effect, even if approved by such holders of KVSB common stock.

The approval of the Charter Proposal requires (1) the affirmative vote of holders of a majority of the voting power of the outstanding shares of KVSB Class A common stock and KVSB Class B common stock, voting together as a single class, (2) the affirmative vote or written consent of the holders of a majority of the voting power of the outstanding shares of KVSB Class K common stock, voting separately as a series (which consent has already been obtained prior to the special meeting) and (3) the affirmative vote or written consent of the holders of a majority of the voting power of the outstanding shares of KVSB Class B common stock, voting separately as a series.

The approval of the Stock Issuance Proposal requires the affirmative vote of the holders of a majority of the votes cast by holders of shares of KVSB Class A common stock and KVSB Class B common stock represented in person or by proxy and entitled to vote thereon, voting together as a single class. The Stock Issuance Proposal is conditioned on the approval of each of the Condition Precedent Proposals. Therefore, if any of the Condition Precedent Proposals is not approved, the Stock Issuance Proposal will have no effect, even if approved by holders of KVSB common stock.

The approval of the Equity Incentive Plan Proposal requires the affirmative vote of a majority of the votes cast by holders of shares of KVSB Class A common stock and KVSB Class B common stock represented in person or by proxy and entitled to vote thereon, voting together as a single class. The Equity Incentive Plan Proposal is conditioned on the approval of each of the Condition Precedent Proposals. Therefore, if any of the Condition Precedent Proposals is not approved, the Equity Incentive Plan Proposal will have no effect, even if approved by holders of KVSB common stock.

The approval of the ESPP Proposal requires the affirmative vote of a majority of the votes cast by holders of shares of KVSB Class A common stock and KVSB Class B common stock represented in person or by proxy and entitled to vote thereon, voting together as a single class. The ESPP Proposal is conditioned on the approval of each of the Condition Precedent Proposals. Therefore, if any of the Condition Precedent Proposals is not approved, the ESPP Proposal will have no effect, even if approved by holders of KVSB common stock.

Voting Your Shares

Each KVSB public share that you own in your name entitles you to one vote at the special meeting. Each proxy card shows the number of common stock, as applicable, that you own. If your shares are held in 'street name' or are in a margin or similar account, you should contact your broker to ensure that votes related to the shares you beneficially own are properly counted.

There are two ways to vote your KVSB common stock at the special meeting:

•You can vote by signing and returning the enclosed proxy card(s). If you vote by proxy card(s), your 'proxy,' whose name is listed on the proxy card(s), will vote your shares as you instruct on the proxy card(s). If you sign and return the proxy card(s) but do not give instructions on how to vote your shares, your shares will be voted as recommended by the KVSB Board 'FOR' the BCA Proposal, 'FOR' the Charter Proposal, 'FOR' each of the Advisory Charter Amendment Proposals, 'FOR' the Stock Issuance Proposal, 'FOR' the Equity Incentive Plan Proposal, 'FOR' the ESPP Proposal, 'FOR' the Adjournment Proposal, in each case, if presented to the special meeting, as applicable. Votes received after a matter has been voted upon at the special meeting, as applicable, will not be counted.

•You can attend the special meeting and vote in person. You will receive a ballot when you arrive. However, if your shares, as applicable, are held in the name of your broker, bank or another nominee, you must get a valid legal proxy from the broker, bank or other nominee. That is the only way KVSB can be sure that the broker, bank or nominee has not already voted your shares.

Revoking Your Proxy

If you are a KVSB stockholder and you give a proxy, you may revoke it at any time before it is exercised by doing any one of the following:

•you may send another proxy card with a later date;

•you may notify KVSB's Secretary in writing before the special meeting that you have revoked your proxy; or

•you may attend the special meeting, as applicable, revoke your proxy, and vote online, as indicated above.

Who Can Answer Your Questions About Voting Your Shares

If you are a stockholder and have any questions about how to vote or direct a vote in respect of your common stock you may call , KVSB's proxy solicitor, by calling or banks and brokers can call collect at , or by emailing .com.

Redemption Rights

Pursuant to our Existing Organizational Documents, public stockholders may seek to redeem their shares for cash if the business combination is consummated, regardless of whether they vote and, if they do vote, irrespective of whether they vote 'for' or 'against' the BCA proposal. Any stockholder holding public shares as of the record date may demand that KVSB redeem such shares for a full pro rata portion of the trust account (which, for illustrative purposes, was approximately $ per share as of , 2021, the record date for the special meeting), calculated as of two business days prior to the anticipated consummation of the business combination. If a holder properly seeks redemption as described in this section and the business combination is consummated, KVSB will redeem these shares for a pro rata portion of funds deposited in the trust account and the holder will no longer own these shares following the business combination.

Notwithstanding the foregoing, a public stockholder, together with any affiliate such holder or any other person with whom such holder is acting in concert or as a 'group' (as defined in Section 13(d)(3) of the Exchange Act), will be restricted from seeking redemption rights with respect to more than 15% of the public shares. Accordingly,

all public shares in excess of 15% held by a public stockholder, together with any affiliate of such holder or any other person with whom such holder is acting in concert or as a 'group,' will not be redeemed for cash.

The Sponsor and the KVSB independent directors will not have redemption rights with respect to any shares of KVSB's common stock owned by them in connection with the Business Combination.

KVSB public stockholders may demand that KVSB redeem their public shares for cash if the business combination is consummated. Public stockholders will be entitled to receive cash for these shares without voting and, if they do vote, irrespective of whether they vote for or against the business combination. Public stockholders may demand redemption by delivering their stock, either physically or electronically using Depository Trust Company's DWAC System, to KVSB's transfer agent prior to the vote at the special meeting. If you hold the shares in street name, you will have to coordinate with your broker to have your shares certificated or delivered electronically. Certificates that have not been tendered (either physically or electronically) in accordance with these procedures will not be redeemed for cash. There is a nominal cost associated with this tendering process and the act of certificating the shares or delivering them through the DWAC system. The transfer agent will typically charge the tendering broker $100 and it would be up to the broker whether or not to pass this cost on to the redeeming stockholder. In the event the proposed business combination is not consummated this may result in an additional cost to stockholders for the return of their shares.

Any request to redeem such shares, once made, may be withdrawn at any time up to the vote on the BCA Proposal. Furthermore, if a public stockholder delivered its certificate in connection with an election of its redemption and subsequently decides prior to the applicable date not to elect to exercise such rights, it may simply request that the transfer agent return the certificate (physically or electronically).

If the business combination is not approved or completed for any reason, then KVSB's public stockholders who elected to exercise their redemption rights will not be entitled to redeem their shares for a full pro rata portion of the trust account, as applicable. In such case, KVSB will promptly return any shares delivered by public stockholders. Additionally, if KVSB would be left with less than $5,000,001 of net tangible assets as a result of the public stockholders properly demanding redemption of their shares for cash, KVSB will not be able to consummate the business combination.

The closing price of KVSB's Class A common stock on , 2021, the record date for the special meeting, was $ per share. The cash held in the trust account on such date was approximately $ ($ per public share). Prior to exercising redemption rights, stockholders should verify the market price of KVSB's common stock as they may receive higher proceeds from the sale of their KVSB common stock in the public market than from exercising their redemption rights if the market price per share is higher than the redemption price. KVSB cannot assure its stockholders that they will be able to sell their shares of KVSB's common stock in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in its securities when its stockholders wish to sell their shares.

If a public stockholder exercises its redemption rights, then it will be exchanging its shares of KVSB's common stock for cash and will no longer own those shares. You will be entitled to receive cash for these shares only if you properly demand redemption no later than the second business day preceding the vote on the BCA Proposal by delivering your stock certificate (either physically or electronically) to KVSB's transfer agent prior to the vote at the special meeting, and the business combination is consummated.

Appraisal Rights

KVSB's stockholders do not have appraisal rights in connection with the Business Combination under the DGCL.

Proxy Solicitation Costs

KVSB is soliciting proxies on behalf of its board of directors. This solicitation is being made by mail but also may be made by telephone or in person. KVSB and its directors, officers and employees may also solicit proxies in person, by telephone or by other electronic means. KVSB will bear the cost of the solicitation.

KVSB has hired to assist in the proxy solicitation process. KVSB will pay that firm a fee of $ plus disbursements. Such fee will be paid with non-trust account funds.

KVSB will ask banks, brokers and other institutions, nominees and fiduciaries to forward the proxy materials to their principals and to obtain their authority to execute proxies and voting instructions. KVSB will reimburse them for their reasonable expenses.

KVSB Initial Stockholders

As of the date of this proxy statement/prospectus, there are 52,767,100 shares of KVSB common stock issued and outstanding, which includes the 10,000,000 founder shares held by the Sponsor and KVSB's independent directors, 1,132,688 private placement shares held by the Sponsor and 41,634,412 public shares.

The Sponsor and KVSB's independent directors have agreed to vote all of their common stock in favor of the proposals being presented at the special meeting.

At any time at or prior to the Business Combination, subject to applicable securities laws (including with respect to material nonpublic information), the Sponsor, the existing stockholders of Nextdoor or our or their respective directors, officers, advisors or respective affiliates may (i) purchase public shares from institutional and other investors who vote, or indicate an intention to vote, against any of the Condition Precedent Proposals, or elect to redeem, or indicate an intention to redeem, public shares, (ii) execute agreements to purchase such shares from such investors in the future, or (ii) enter into transactions with such investors and others to provide them with incentives to acquire public shares, vote their public shares in favor of the Condition Precedent Proposals or not redeem their public shares. Such a purchase may include a contractual acknowledgement that such stockholder, although still the record holder of KVSB's shares, is no longer the beneficial owner thereof and therefore agrees not to exercise its redemption rights. In the event that the Sponsor, the existing stockholders of Nextdoor or our or their respective directors, officers, advisors, or respective affiliates purchase shares in privately negotiated transactions from public stockholders who have already elected to exercise their redemption rights, such selling stockholders would be required to revoke their prior elections to redeem their shares. The purpose of such stock purchases and other transactions would be to increase the likelihood of (1) satisfaction of the requirement that the BCA Proposal, the Charter Proposal, the Equity Incentive Plan Proposal, the ESPP Proposal and the Adjournment Proposal by a requisite vote of our stockholders, (2) satisfaction of the Minimum Cash Condition, (3) otherwise limiting the number of public shares electing to redeem and (4) KVSB's net tangible assets (as determined in accordance with Rule 3a51(g)(1) of the Exchange Act) being at least $5,000,001. Entering into any such arrangements may have a depressive effect on the common stock (e.g., by giving an investor or holder the ability to effectively purchase shares at a price lower than market, such investor or holder may therefore become more likely to sell the shares he or she owns, either at or prior to the Business Combination).

If such transactions are effected, the consequence could be to cause the Business Combination to be consummated in circumstances where such consummation could not otherwise occur. Purchases of shares by the persons described above would allow them to exert more influence over the approval of the proposals to be presented at the special meeting and would likely increase the chances that such proposals would be approved. We will file or submit a Current Report on Form 8-K to disclose any material arrangements entered into or significant purchases made by any of the aforementioned persons that would affect the vote on the proposals to be put to the special meeting or the redemption threshold. Any such report will include descriptions of any arrangements entered into or significant purchases by any of the aforementioned persons.

BCA PROPOSAL

Overview

KVSB is asking its stockholders to approve and adopt the Merger Agreement, certain related agreements and the transactions contemplated thereby (including the Merger). KVSB stockholders should read carefully this proxy statement/prospectus in its entirety for more detailed information concerning the Merger Agreement, which is attached as Annex A to this proxy statement/prospectus, and the transactions contemplated thereby. Please see '- The Merger Agreement' below for additional information and a summary of certain terms of the Merger Agreement. You are urged to read carefully the Merger Agreement in its entirety before voting on this proposal.

Because KVSB is holding a stockholder vote on the Merger, KVSB may consummate the Merger only if it is approved by the affirmative vote of the holders of a majority of the outstanding KVSB Class A common stock and KVSB Class B common stock that are voted at the special meeting.

The Merger Agreement

This subsection of the proxy statement/prospectus describes the material provisions of the Merger Agreement but does not purport to describe all of the terms of the Merger Agreement. The following summary is qualified in its entirety by reference to the complete text of the Merger Agreement, which is attached as Annex A to this proxy statement/prospectus. You are urged to read the Merger Agreement in its entirety because it is the primary legal document that governs the Merger.

The Merger Agreement contains representations, warranties and covenants that the respective parties made to each other as of the date of the Merger Agreement or other specific dates. The assertions embodied in those representations, warranties and covenants were made for purposes of the contract among the respective parties and are subject to important qualifications and limitations agreed to by the parties in connection with negotiating the Merger Agreement. The representations, warranties and covenants in the Merger Agreement are also modified in part by the underlying disclosure schedules (the 'disclosure schedules'), which are not filed publicly and were used for the purpose of allocating risk among the parties rather than establishing matters as facts. We do not believe that the disclosure schedules contain information that is material to an investment decision. Additionally, the representations and warranties of the parties to the Merger Agreement may or may not have been accurate as of any specific date and do not purport to be accurate as of the date of this proxy statement/prospectus. Accordingly, no person should rely on the representations and warranties in the Merger Agreement or the summaries thereof in this proxy statement/prospectus as characterizations of the actual state of facts about KVSB, the Sponsor, Nextdoor or any other matter.

Material Adverse Effect

Under the Merger Agreement, certain representations and warranties of Nextdoor and KVSB and Merger Sub are qualified in whole or in part by materiality thresholds. In addition, certain representations and warranties of Nextdoor and KVSB and Merger Sub are qualified in whole or in part by a material adverse effect standard for purposes of determining whether a breach of such representations and warranties has occurred.

Pursuant to the Merger Agreement, a material adverse effect with respect to Nextdoor ('Nextdoor Material Adverse Effect') means any event, state of facts, development, circumstance, occurrence or effect that (a) has had, or would reasonably be expected to have, individually or in the aggregate, a material adverse effect on the business, assets, results of operations or financial condition of Nextdoor and its subsidiaries, taken as a whole or (b) does or would reasonably be expected to, individually or in the aggregate, prevent, materially delay or materially impair the ability of Nextdoor to consummate the Merger.

However, in no event would any of the following, alone or in combination, be deemed to constitute, or be taken into account in determining whether there has been or will be, a 'Nextdoor Material Adverse Effect':

(i)any change in applicable Laws, GAAP or any COVID-19 measures or any interpretation thereof following the date of the Merger Agreement,

(ii)any change in interest rates or economic, political, business or financial market conditions generally,

(iii)the taking of any action required by the Merger Agreement,

(iv)any natural disaster (including hurricanes, storms, tornados, flooding, earthquakes, volcanic eruptions or similar occurrences), pandemic, outbreak of disease or illness or public health event (including COVID-19) or change in climate,

(v)any acts of terrorism or war, the outbreak or escalation of hostilities, geopolitical conditions, local, national or international political conditions,

(vi)any failure of Nextdoor to meet any projections or forecasts (provided that clause (vi) shall not prevent a determination that any event not otherwise excluded from the definition of Nextdoor Material Adverse Effect underlying such failure to meet budgets, projections or forecasts has resulted in a Nextdoor Material Adverse Effect),

(vii)any events generally applicable to the industries or markets in which Nextdoor and its subsidiaries operate (including increases in the cost of products, supplies, materials or other goods purchased from third-party suppliers),

(viii)the announcement of the Merger Agreement and consummation of the transactions contemplated thereby, including any termination of, reduction in or similar adverse impact (but in each case only to the extent attributable to such announcement or consummation) on relationships, contractual or otherwise, with any landlords, customers, suppliers, distributors, partners or employees of Nextdoor and its subsidiaries (it being understood that this clause (viii) shall be disregarded for purposes of the representation and warranty related to no conflicts of Nextdoor and the condition to Closing with respect thereto),

(ix)the taking by Nextdoor and its subsidiaries of any COVID-19 response measures, or

(x)any action taken by, or at the request of, KVSB or Merger Sub.

Any event referred to in clauses (i), (ii), (iv), (v) or (vii) above may be taken into account in determining if a Nextdoor Material Adverse Effect has occurred to the extent it has a disproportionate and adverse effect on the business, assets, results of operations or condition (financial or otherwise) of Nextdoor and its subsidiaries, taken as a whole, relative to similarly situated companies in the industry in which Nextdoor and its subsidiaries conduct their respective operations, but only to the extent of the incremental disproportionate effect on Nextdoor and its subsidiaries, taken as a whole, relative to similarly situated companies in the industry in which Nextdoor and its subsidiaries conduct their respective operations.

Forward Purchase Agreement

In connection with the closing of KVSB's initial public offering, the Sponsor entered into the Forward Purchase Agreement pursuant to which the Sponsor (together with any permitted transferees under the Forward Purchase Agreement) agreed to purchase, upon the closing of KVSB's initial business combination, an aggregate of up to 1,000,000 shares of KVSB Class A common stock, for an aggregate purchase price of up to $10,000,000, or $10.00 per share of KVSB Class A common stock. The proceeds from the sale of these forward-purchase shares, together with the amounts available to KVSB from the trust account (after giving effect to any redemptions of public shares) and any other equity or debt financing obtained by it in connection with the Business Combination, will be used to satisfy the cash requirements of the Business Combination, including funding the purchase price and paying expenses and retaining specified amounts to be used by the post-Business Combination company for working capital or other purposes. To the extent that the amounts available from the trust account and other financing are sufficient for such cash requirements, the Sponsor may purchase less than 1,000,000 forward-purchase shares.

Background to the Business Combination

KVSB is a blank check company incorporated in Delaware on January 29, 2021. KVSB was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination, with one or more businesses or entities. The Business Combination is the result of a search for a potential transaction using the network, investing and operating experience of the Sponsor, KVSB's

105

management team and the KVSB Board. The terms of the Business Combination are the result of arm's-length negotiations between representatives of KVSB and representatives of Nextdoor over the course of approximately two and a half months. The following is a brief description of the background of the Business Combination and related transactions.

In March 2021, KVSB completed its initial public offering of 41,634,412 shares of Class A common stock, at $10.00 per share, including 1,634,412 shares sold pursuant to a partial exercise of the underwriters' over-allotment option, generating gross proceeds to KVSB of $416.3 million, and incurring offering costs of approximately $23.6 million, inclusive of approximately $14.6 million in deferred underwriting commissions. Substantially concurrently with the closing of the initial public offering, KVSB completed the private sale of 1,132,688 shares of Class A common stock, at a price of $10.00 per share, to the Sponsor, generating aggregate gross proceeds to KVSB of approximately $11.3 million. Following the closing of the initial public offering, a total of $416.3 million of the net proceeds of the initial public offering and certain of the proceeds of the private placement was deposited into the trust account established for the benefit of KVSB's public stockholders, and the remaining proceeds became available to be used to provide for business, legal and accounting due diligence on prospective business combinations and continuing general and administrative expenses. Prior to the consummation of the initial public offering, neither KVSB nor anyone on its behalf contacted any prospective target business or had any substantive discussions, formal or otherwise, with respect to a transaction with KVSB.

Following its initial public offering, KVSB commenced a search for prospective businesses and assets to acquire. Representatives of KVSB contacted, and were contacted by, a number of individuals and entities with respect to potential business combination opportunities. KVSB's management team compiled a list of high priority potential targets and updated and supplemented such list from time to time. KVSB's goal was to identify private, high-quality growth companies addressing large market opportunities with highly differentiated, proprietary technology. KVSB believes its management team and advisors have substantial expertise and background as investors in companies spanning a number of industries, including social networking and advertising, as well as a wide and active network of relationships in those industries. Because of this combination of strengths, KVSB was able to rapidly and efficiently evaluate a wide range of potential business combination targets to determine which ones met its transaction criteria.

In the process that led to identifying Nextdoor as an attractive investment opportunity, KVSB evaluated more than 15 potential business combination targets and engaged with three of the potential targets. KVSB performed financial and industry due diligence and held meetings with the management teams of two of the potential targets (including Nextdoor, as discussed below; and such other potential target, 'Company A'). KVSB did not proceed to signing a letter of intent and exclusivity agreement with any of the potential targets other than Nextdoor for various reasons, including KVSB's concerns over product commercialization, valuation, strength of team, business model, capital needs and other reasons based on its diligence and significant historical experience evaluating investment opportunities.

On April 20, 2021, KVSB initiated contact with Company A to discuss the potential mutual benefits of pursuing a business combination. Between April 20, 2021 and April 30, 2021, the parties held a series of calls and in-person meetings and exchanged e-mails as part of KVSB's diligence process. On April 29, 2021, KVSB sent an email to the KVSB Board containing a detailed summary of the due diligence produced by the KVSB management team in connection with its review of Company A. However, the discussions between KVSB and Company A gradually diminished, primarily as a result of KVSB's concerns about Company A's ability to commercialize its product at scale. KVSB management and the KVSB Board determined that Nextdoor met its search criteria and that the Nextdoor opportunity was superior to the other targets with which it had met.

On April 20, 2021, Morgan Stanley & Co. LLC ('Morgan Stanley') initiated contact with KVSB. Between April 20, 2021 and May 24, 2021, the parties held a series of calls and in-person meetings and exchanged e-mails as part of KVSB's diligence process.

On April 21, 2021, KVSB and Nextdoor executed a mutual non-disclosure agreement.

106

On April 29, 2021, after the non-disclosure agreement was executed, members of the KVSB team attended a video conference meeting with representatives of Morgan Stanley and Evercore Group LLC (financial advisor to Nextdoor) ('Evercore') to review certain financial and other information provided by Nextdoor related to its business.

Vinod Khosla, Founder of KVSB, and David Weiden, a managing director of Khosla Ventures, are both acquainted with Sarah Friar, Chief Executive Officer and President of Nextdoor. On April 29, 2021, Mr. Khosla, Mr. Weiden and Ryno Blignaut, a consultant to KVSB, attended a video conference meeting with Ms. Friar, Mike Doyle, the Chief Financial Officer of Nextdoor and other members of Nextdoor management and certain representatives of Morgan Stanley and Evercore to explore the merits of a potential business combination transaction between Nextdoor and KVSB.

Between April 29, 2021 and May 5, 2021, members of the KVSB team conducted a detailed business and financial due diligence review of Nextdoor.

On May 6, 2021, Mr. Weiden and Mr. Blignaut held two separate meetings via video teleconference with Mr. Doyle of Nextdoor and other members of Nextdoor management to conduct a detailed financial analysis of Nextdoor and its business operations.

On May 7, 2021, Mr. Khosla, Mr. Weiden and Mr. Blignaut held a meeting via video teleconference with Ms. Friar and Mr. Doyle of Nextdoor, and representatives of Morgan Stanley and Evercore to discuss the initial parameters of a business combination.

Between May 6, 2021 and May 12, 2021, representatives of KVSB had multiple telephone conversations and e-mail exchanges with representatives of Nextdoor to conduct additional business and financial due diligence, including several diligence meetings focused on Nextdoor's financial plan, and Nextdoor continued to provide information to KVSB regarding Nextdoor and its business operations.

Between May 7, 2021 and May 9, 2021, Mr. Khosla and Ms. Friar had multiple discussions regarding the valuation of Nextdoor. During such discussions, Ms. Friar shared information prepared by Nextdoor regarding a potential valuation of Nextdoor.

On May 12, 2021, KVSB held a meeting of the board of directors of KVSB via teleconference. During the meeting, the independent directors not affiliated with the Sponsor expressed their support of the potential business combination being discussed with Nextdoor and determined it was advisable to proceed with the negotiation of a potential transaction with Nextdoor.

Later on May 12, 2021, Mr. Khosla and Samir Kaul in his capacity as Chief Executive Officer of KVSB, e-mailed to Ms. Friar an initial draft non-binding letter of intent, which included, subject to further due diligence, an initial pre-transaction equity value for Nextdoor of $3.5 billion. The initial draft non-binding letter of intent contemplated that the total consideration payable to Nextdoor's equity holders (including holders of equity awards and other exchangeable and convertible securities which would be converted into equivalent securities of Nextdoor) would be $3.5 billion and in the form of shares of common stock or equivalent securities of Nextdoor valued at $10.00 per share. The initial letter of intent also contemplated the creation of a customary post-closing equity incentive plan by Nextdoor, a PIPE Investment in a mutually agreeable amount and a 45-day exclusivity period. The $3.5 billion equity value was based on KVSB management's analysis of certain preliminary due diligence, KVSB management's further analysis of Nextdoor's business model, detailed analysis of Nextdoor's business and growth potential, the valuation information provided by Nextdoor, other materials provided by Nextdoor's management and an analysis of comparable companies in certain industries, including other social media companies. In formulating its own valuation of Nextdoor, KVSB management considered the illustrative valuation of Nextdoor and the methodologies underlying such illustrative valuation included in the information provided by management of Nextdoor.

Following the submission of the initial draft non-binding letter of intent, numerous meetings via teleconference were held and e-mails were exchanged among representatives of KVSB and Nextdoor, to discuss, among other things, Nextdoor's feedback on the initial draft non-binding letter of intent.

107

On May 23, 2021, Morgan Stanley, as representative of, and as directed by, Nextdoor, e-mailed to representatives of KVSB a counterproposal on certain key terms of the potential transaction. Nextdoor's counterproposal generally accepted KVSB's proposed pre-transaction equity value of $3.5 billion, but would in addition require among other things (i) a minimum cash condition at closing (after redemptions and payment of all transaction expenses) of at least $500 million, (ii) a commitment from the sponsor to invest $50 million on the same terms as the PIPE investment, (iii) a lock-up of all sponsor shares for 12 months with no early release based on trading triggers, and (iv) high-vote shares for all existing equityholders of Nextdoor. The Nextdoor counter-proposal also contemplated that all of the outstanding shares of Class B common stock and Class K common stock would convert into a fixed number of shares of Nextdoor common stock on closing equivalent to a 20% promote at the time of the initial public offering (with a forfeiture of the remaining shares that would have provided an up to 30% in the aggregate promote that could have been achieved based on future trading targets) and the holders of such shares would waive any anti-dilution adjustment to the conversion ratio of such shares, with the converted Class K common stock being fully vested.

After further discussions between representatives of KVSB and Nextdoor, on May 24, 2021, Latham & Watkins LLP, as representatives of KVSB ('Latham'), e-mailed to Morgan Stanley, as representatives of Nextdoor, a revised draft of the non-binding letter of intent. From May 24, 2021 through May 27, 2021, various discussions were held between the parties, including Fenwick & West LLP, as representative of Nextdoor ('Fenwick'), and Evercore around the terms of the proposed transaction and multiple drafts of the non-binding letter of intent were exchanged.

On May 27, 2021, Morgan Stanley and Evercore sent via e-mail, on behalf of Nextdoor, a proposed final form of the non-binding letter of intent as a result of the negotiations between the parties. After reviewing the terms of the proposed final form of the non-binding letter of intent (including comparisons with KVSB's initial draft non-binding letter of intent and Nextdoor management's initial counterproposal), effective as of May 27, 2021, Mr. Kaul, in his capacity of Chief Executive Officer of KVSB, on behalf of KVSB, and Ms. Friar, in her capacity of Chief Executive Officer and President of Nextdoor, on behalf of Nextdoor, executed the agreed final version of the non-binding letter of intent (the 'LOI') regarding a potential business combination transaction (subject to due diligence and negotiation of definitive agreements) involving KVSB and Nextdoor. The LOI provided for the following terms, among others:

•KVSB would acquire all of the outstanding equity interests in Nextdoor (including equity awards and other exercisable and convertible securities) by reverse triangular merger (or similar structure mutually agreed by the parties);

•the parties agreed to a pre-transaction equity value for Nextdoor of $3.5 billion (including vested and unvested equity awards and other exercisable or convertible securities of Nextdoor, but with the total number of shares issuable in respect of outstanding options calculated on the basis of the treasury share method), with no adjustment for Nextdoor's cash, debt, working capital, non-cash assets or non-debt liabilities;

•KVSB would raise no less than $200 million through the PIPE Investment, which would be committed upon signing of the definitive agreement in respect of the transaction, and the Sponsor would agree to invest up to $50 million of the PIPE Investment (as determined by Nextdoor in consultation with KVSB);

•(i) Nextdoor would have the right to designate all of the directors of Nextdoor following the business combination, including independent directors as are required to comply with stock exchange and other

108

regulatory requirements, (ii) the Nextdoor management team would consist of the current Nextdoor management team, and (iii) Mr. Khosla would have the right to attend meetings of the board of directors of Nextdoor as an observer;

•the definitive transaction agreement would include a customary closing condition (benefiting Nextdoor only) that KVSB have at least $400 million in cash and cash equivalents at closing after giving effect to all stockholder redemptions and payment of all Nextdoor and KVSB transaction expenses and to funds raised from the PIPE Investment and pursuant to the Forward Purchase Agreement (if any);

•on closing, all of the outstanding shares of Class B common stock and Class K common stock would convert into 10,408,603 shares of New Nextdoor Class B common stock (which is equivalent to a 20% promote at the time of the initial public offering (with a forfeiture of the remaining shares that would have provided an up to 30% in the aggregate promote that could have been achieved based on future trading targets)), with the converted Class K common stock being fully vested, and the holders of shares of Class B common stock and Class K common stock would waive any anti-dilution adjustment to the conversion ratio of such shares provided for under the Existing Charter; and

•each of KVSB and Nextdoor would be subject to an exclusivity period from the date of the LOI until the earlier of (i) 5:00 p.m. Pacific Time, on July 11, 2021 (which would be automatically extended to July 26, 2021 if as of July 11, 2021 unless either party has provided notice on or before such date that it wishes to terminate exclusivity) and (ii) the date, if any, on which KVSB and Nextdoor enter into a definitive agreement with respect to the proposed transaction.

On May 27, 2021, Morgan Stanley held a 'kick-off' videoconference call at which representatives of Latham, Fenwick, KVSB, Morgan Stanley, Evercore, and Nextdoor, participated in a meeting to discuss certain process matters regarding the preparation of definitive transaction documents, prospective legal due diligence, prospective business due diligence, the PIPE Investment and related work streams, the preparation of the S-4 and related work streams, including the anticipated timeline discussed by the parties in connection with the execution of the LOI, which contemplated that signing and announcement of the proposed transaction would occur in July 2021.

On May 28, 2021, representatives of Latham, on behalf of KVSB, and representatives of Fenwick, on behalf of Nextdoor, held a telephone conference call to discuss certain process matters regarding the preparation of definitive transaction documents, legal due diligence, the PIPE Investment and related work streams, including the anticipated timeline discussed by the parties in connection with the execution of the LOI, which contemplated that signing and announcement of the proposed transaction would occur by the beginning of July 2021.

Beginning on June 10, 2021, representatives of Morgan Stanley and Evercore began contacting a limited number of potential PIPE Investors, each of whom agreed to maintain the confidentiality of the information received pursuant to customary non-disclosure agreements, to discuss Nextdoor, the proposed business combination and the PIPE Investment and to determine such investors' potential interest in participating in the PIPE Investment. During the weeks of June 7, 2021, June 14, 2021 and June 21, 2021, representatives of KVSB and Nextdoor and Morgan Stanley and Evercore (in their capacity as KVSB's placement agents) participated in various virtual meetings with prospective participants in the PIPE Investment.

During the meeting, Mr. Kaul updated the KVSB Board regarding the status of the proposed transaction with Nextdoor, including the PIPE Investment, and discussed key considerations related to the proposed transaction (including the rationale for the combined business). Representatives of Latham provided an overview of its legal due diligence findings. Representatives of Latham then gave a presentation to the KVSB Board on the directors' fiduciary duties under Delaware law and summarized the key terms of the Merger Agreement and ancillary transaction documents (copies of all of which were provided to all of the members of the KVSB Board in advance of the meeting). During the presentation, the KVSB Board asked, and the advisors answered, questions about the matters presented. The KVSB Board, with the assistance of Latham, reviewed and discussed the proposed business combination, including Nextdoor as the proposed business combination target, the total merger consideration based on the equity valuation of $3.5 billion, the terms and conditions of the Merger Agreement and the key ancillary agreements, the potential benefits of, and risks relating to, the proposed business combination, and the reasons for entering into the Merger Agreement. See the section entitled '- KVSB's Board of Directors Reasons for the Business Combination' for additional information related to the factors considered by the KVSB Board in approving the Business Combination. Following this discussion, the KVSB Board unanimously approved the Merger and the other transactions contemplated by the Merger Agreement and the entry into the Merger Agreement and the documents contemplated thereby and unanimously recommended that the stockholders of KVSB approve the Business Combination.

KVSB's Board of Directors' Reasons for the Business Combination

The KVSB Board, in evaluating the Business Combination, consulted with the Sponsor, KVSB's management and its legal and other advisors. In reaching its conclusion (i) that the terms and conditions of the Merger Agreement and the transactions contemplated thereby are advisable, fair to and in the best interests of KVSB and its stockholders and (ii) to recommend that the stockholders adopt the Merger Agreement and approve the Business Combination, the KVSB Board considered and evaluated a number of factors, including, but not limited to, the factors discussed below. In light of the number and wide variety of factors considered in connection with its evaluation of the Business Combination, the KVSB Board did not consider it practicable to, and did not attempt to, quantify or otherwise assign relative weights to the specific factors that it considered in reaching its determination and supporting its decision. The KVSB Board viewed its decision as being based on all of the information available and the factors presented to and considered by it. In addition, individual directors may have given different weight to different factors. This explanation of KVSB's reasons for the Business Combination and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under 'Cautionary Statement Regarding Forward-Looking Statements.'

In evaluating the Business Combination, the KVSB Board and management considered (i) the general criteria and guidelines that KVSB believed would be important in evaluating prospective target businesses as described in the prospectus for KVSB's initial public offering and (ii) that they could enter into a business combination with a target business that does not meet those criteria and guidelines. In the prospectus for its initial public offering, KVSB stated that it intended to seek a business combination with a business:

•addressing a large market that creates the opportunity for attractive long-term growth prospects;

•protected by proprietary technology advantages;

•that has achieved sufficient technology and business maturity while maintaining significant topline growth potential;

•with a creative and ambitious management team with a proven track record of success;

•pursuing significant technology innovation that has the potential to have a significant positive impact on the world;

•with rapid innovation cycles;

•that maintains strong and defensible competitive advantages, which KVSB believes over time will lead to durable and profitable growth; and

•where KVSB can materially impact the value of the company in partnership with management.

The KVSB Board determined that the Business Combination was an attractive business opportunity that met the vast majority of the criteria and guidelines above. The KVSB Board considered a number of additional factors pertaining to the Business Combination as generally supporting its decision to enter into the Merger Agreement and the transactions contemplated thereby, including but not limited to, the following material factors:

•Network effects plus online and offline connection is unique.The KVSB Board considered the fact that Nextdoor's business can strengthen as its community scales. Nextdoor's focus on physical neighborhoods has allowed it to optimize its product and strategy to drive neighbor growth and engagement on its platform. Historically, as neighborhood adoption increased, activity among neighbors also increased, adding more relevant local content. This has prompted more engagement from other neighbors, leading to further growth through word of mouth and an enhanced overall experience that strengthens neighbor retention. Other major stakeholders in the neighborhood, such as businesses and public agencies also contribute to this flywheel of growth. Further, the KVSB Board believes that the Nextdoor platform is unique in its ability to enable online and real-world connections between neighbors, businesses, and public agencies which are a valuable part of the neighborhood ecosystem.

113

•Team well positioned for acceleration and execution.The KVSB Board considered the fact that Nextdoor after the business combination will be led by the senior management team of Nextdoor. The KVSB Board also believes that the willingness of Nextdoor's management team to roll over their equity stake and agree to prohibitions on the transfer of their Nextdoor equity for a period of time following the consummation of the Business Combination reflected management's belief in and commitment to Nextdoor's continued growth following the consummation of the Business Combination.

•Other alternatives.The KVSB Board believes, after a review of other business combination opportunities reasonably available to KVSB, that the Business Combination represents the best initial business combination for KVSB and the most attractive opportunity for KVSB's management to accelerate its business plan based upon the process used to evaluate and assess other potential acquisition targets, and the KVSB Board's belief that such process has not presented a better alternative.

114

The KVSB Board also considered a variety of uncertainties and risks and other potentially negative factors concerning the Business Combination, including, but not limited to, the following:

•Liquidation of KVSB.The risks and costs to KVSB if the Business Combination is not completed, including the risk of diverting management focus and resources from other businesses combination opportunities, which could result in KVSB being unable to effect a business combination within the timeframe provided for under its Existing Charter and forcing KVSB to liquidate.

•Exclusivity.The fact that the Merger Agreement includes an exclusivity provision that prohibits KVSB from soliciting other business combination proposals and restricts KVSB's ability to consider other potential business combinations so long as the Merger Agreement is in effect.

•Stockholder vote.The risk that KVSB's stockholders may fail to provide the respective votes necessary to effect the Business Combination.

•Redemption risk.The KVSB Board considered the risk that the current public stockholders of KVSB would redeem their public shares for cash in connection with consummation of the Business Combination, thereby reducing the amount of cash available to Nextdoor following the consummation of the Business Combination and potentially allowing Nextdoor to terminate the Business Combination or, at Nextdoor's election, waive the condition under the Merger Agreement requiring that the funds in the trust account (after giving effect to redemptions and after the payment of deferred underwriting commissions and other transaction expenses of KVSB and Nextdoor), together with the PIPE Investment Amount and the amounts funded under the Forward Purchase Agreement (if any), is equal to or exceeds $400.0 million, in order for the Business Combination to be consummated. As of June 30, 2021, without giving effect to any future redemptions that may occur, the trust account had approximately $416.4 million invested in U.S. Treasury securities and money market funds that invest in U.S. government securities.

•Post-business combination corporate governance.The KVSB Board considered the corporate governance provisions of the Merger Agreement and the proposed material provisions of the Proposed Governing Documents and the effect of those provisions on the governance of Nextdoor. See '- The Merger Agreement' and 'Management of Nextdoor Following the Business Combination' for detailed discussions of the terms and conditions of these documents.

•Limitations of review.The KVSB Board considered that it was not obtaining a third-party valuation or fairness opinion from any independent investment banking or accounting firm. In addition, KVSB's management and outside counsel reviewed only certain materials in connection with their due diligence review of Nextdoor. Accordingly, the KVSB Board considered that KVSB may not have properly valued Nextdoor.

•Closing conditions.The fact that completion of the Business Combination is conditioned on the satisfaction of certain closing conditions that are not within KVSB's control.

•KVSB public stockholders holding a minority position in Nextdoor. The fact that KVSB's public stockholders will hold a minority position in the post-combination company (approximately 10.9% of the ownership and 1.3% of the voting power, assuming that no shares of KVSB Class A common stock are elected to be redeemed by KVSB's public stockholders), which may reduce the influence that KVSB's current stockholders have on the management of Nextdoor.

•No survival of remedies for breach of representations, warranties or covenants of Nextdoor.The KVSB Board considered that the terms of the Merger Agreement provide that KVSB will not have any surviving remedies against Nextdoor after the Closing to recover for losses as a result of any inaccuracies or breaches of Nextdoor's representations, warranties or covenants set forth in the Merger Agreement. As a result, KVSB stockholders could be adversely affected by, among other things, a decrease in the financial performance or worsening of financial condition of Nextdoor prior to the Closing, whether determined before or after the Closing, without any ability to reduce the number of shares of Nextdoor common stock to be issued in the Business Combination or recover for the amount of any damages. The KVSB Board

115

determined that this structure was appropriate and customary in light of the fact that it is consistent with market practice for similar transactions and Nextdoor would not have proceeded with the Business Combination otherwise.

•Litigation.The possibility of litigation challenging the Business Combination or that an adverse judgment granting injunctive relief could indefinitely delay or otherwise permanently prohibit consummation of the Business Combination.

•Fees and expenses.The fees and expenses associated with completing the Business Combination.

•Other risks.Various other risks associated with the Business Combination, the business of KVSB and the business of Nextdoor described under the section entitled 'Risk Factors.'

In addition to considering the factors described above, the KVSB Board also considered that certain officers and directors of KVSB may have interests in the Business Combination as individuals that are in addition to, and that may be different from, the interests of KVSB's stockholders (see '- Interests of KVSB's Directors and Executive Officers in the Business Combination'). However, the KVSB Board concluded that the potentially disparate interests would be mitigated because, among other reasons, (i) certain of these interests were disclosed in the prospectus for KVSB's initial public offering and are included in this proxy statement/prospectus, (ii) these disparate interests would exist with respect to a business combination by KVSB with any other target business or businesses and (iii) the Business Combination was structured so that it may be completed even if KVSB's public stockholder redeem a substantial portion of the KVSB Class A common stock.

The KVSB Board concluded that the potential benefits that it expected KVSB and its stockholders to achieve as a result of the Business Combination outweighed the potentially negative factors associated with the Business Combination. Accordingly, the KVSB Board unanimously determined that the Merger Agreement and the Business Combination were advisable, fair to, and in the best interests of, KVSB and its stockholders.

Projected Financial Information

Nextdoor provided KVSB with its internally prepared forecasts through the year ending December 31, 2022. Nextdoor does not as a matter of course make public projections as to future revenue, earnings, or other results. However, the management of Nextdoor has prepared the prospective financial information set forth below to present key elements to the forecasts provided to KVSB. The accompanying prospective financial information was not prepared with a view toward public disclosure or with a view toward complying with the guidelines established by the American Institute of Certified Public Accountants with respect to prospective financial information, but, in the view of Nextdoor's management, was prepared on a reasonable basis, reflects the best currently available estimates and judgments, and presents, to the best of management's knowledge and belief, the expected course of action and the expected future financial performance of Nextdoor. However, this information is not fact and should not be relied upon as being necessarily indicative of future results, and readers of this proxy statement/prospectus are cautioned not to place undue reliance on the prospective financial information.

Neither Ernst & Young LLP, nor any other independent accountants, have compiled, reviewed, examined, or performed any procedures with respect to prospective financial information contained herein, nor have they expressed any opinion or any other form of assurance on such information or its achievability, and assume no responsibility for, and disclaim any association with, the information. The report of Ernst & Young LLP included in this proxy statement/prospectus relates to Nextdoor's historical audited financial statements and does not extend to the unaudited prospective financial information and should not be read to do so.

The projections are forward-looking statements that are based on assumptions and estimates that are inherently uncertain and, though considered reasonable by Nextdoor's management as of the date of its preparation, are subject to a wide variety of significant business, economic, and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information, including, among others, those risks and uncertainties set forth in the sections entitled 'Risk Factors,' 'Nextdoor's Management's Discussion and Analysis of Financial Condition and Results of Operations,' and 'Cautionary Statement Regarding Forward-Looking Statements' sections of this proxy statement/prospectus. The prospective financial information is subjective

116

in many respects and, since the prospective financial information covers multiple years, that information by its nature becomes less predictive with each successive year. Accordingly, there can be no assurance that the prospective results are indicative of the future performance of Nextdoor or that actual results will not differ materially from those presented in the prospective financial information. Furthermore, the prospective financial information does not take into account any circumstances or events occurring after the date that information was prepared.

The financial projections were requested by, and disclosed to, KVSB for use as a component in its overall evaluation of Nextdoor and are included in this proxy statement/prospectus on that account. Key assumptions were made with the best available information and estimates, including, but not limited to:

•the sustained growth, year over year, of Nextdoor's membership (neighbors), in particular in the United States;

•the engagement of Nextdoor's neighbors based on the sustained growth of average weekly active users in the past three years and projected growth of the same through the end of the year ending December 31, 2022; and

•historical growth of Nextdoor's average revenue per user over the last three years and the projected average revenue per user growth through the end of the year ending December 31, 2022, including the underlying analysis of these projections prepared by Nextdoor's management.

Inclusion of the prospective financial information in this proxy statement/prospectus should not be regarded as a representation by Nextdoor, KVSB or any other person that the results contained in the prospective financial information will be achieved, and should not be regarded as an indication that KVSB, the KVSB Board, or their respective affiliates, advisors or other representatives considered, or now considers, such financial projections necessarily to be predictive of actual future results or to support or fail to support your decision whether to vote for or against the Business Combination. You are cautioned not to rely on the projections in making a decision regarding the transaction, as the projections may be materially different than actual results. We will not refer back to the financial projections in our future periodic reports filed under the Exchange Act.

Nextdoor does not expect to generally publish its business plans and strategies or make external disclosures of its anticipated financial position or operating results in the manner provided to KVSB in connection with the Business Combination. Accordingly, Nextdoor does not intend to update or otherwise revise the projected financial information provided to KVSB to reflect circumstances existing since its preparation or to reflect the occurrence of unanticipated events, even in the event that any or all of the underlying assumptions are shown to be in error. Furthermore, Nextdoor does not intend to update or revise the projected financial information provided to KVSB to reflect changes in general economic or industry conditions.

Additional information relating to the principal assumptions used in preparing the projections is set forth below. See 'Risk Factors' for a discussion of various factors that could materially affect New Nextdoor's financial condition, operating results, business, prospects and the price of New Nextdoor's Class A common stock.

The key elements of the projections provided by management of Nextdoor to KVSB are summarized in the table below:


($ in millions)	2021E	2022E
Total Revenue	$178	$249
Total ARPU	$5.93	$6.47
Operating Expenses	$280	$352
Net Loss	$(103)	$(103)
Non-GAAP Operating Expenses(1)	$228	$294
Adjusted EBITDA(2)	$(50)	$(45)

117

___________________

(1)Non-GAAP Operating Expenses includes cost of revenue, sales and marketing, research and development, and general and administrative expenses, excluding depreciation and amortization, stock-based compensation, and acquisition-related costs.

(2)Adjusted EBITDA is a non-GAAP financial measure that represents Nextdoor's net loss, adjusted for depreciation and amortization, stock-based compensation, net interest income, provision for income taxes, and acquisition-related costs. For a historical reconciliation of Adjusted EBITDA to the most directly comparable GAAP measure of net loss, see the section entitled 'Management's Discussion and Analysis of Financial Condition and Results of Operations-Non-GAAP Financial Measure.'

Projected revenue and ARPU are based on a variety of operational assumptions, including an increase in the number of neighbors that use the Nextdoor platform, including in markets outside of the United States, increasing engagement of those neighbors, and further monetization of the Nextdoor platform, including through the scaling of its advertising business and developing new revenue streams.

Projected GAAP and non-GAAP operating expenses are driven by Nextdoor's level of investments in the business. Net loss and Adjusted EBITDA are driven by Nextdoor's projected revenue and its level of investments, including in (i) research and development to develop new products and features, (ii) sales and marketing expenses due to continued investment in sales activities, increased investment in marketing to acquire small and mid-sized customers, and further investment in international expansion and (iii) general and administrative expenses to support growth as well as due to additional costs associated with legal, accounting, compliance, investor relations, and other costs of becoming a public company.

EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE FEDERAL SECURITIES LAWS, BY INCLUDING IN THIS PROXY STATEMENT/PROSPECTUS A SUMMARY OF THE FINANCIAL PROJECTIONS FOR NEXTDOOR, EACH OF KVSB AND NEXTDOOR UNDERTAKES NO OBLIGATIONS AND EXPRESSLY DISCLAIMS ANY RESPONSIBILITY TO UPDATE OR REVISE, OR PUBLICLY DISCLOSE ANY UPDATE OR REVISION TO, THESE FINANCIAL PROJECTIONS TO REFLECT CIRCUMSTANCES OR EVENTS, INCLUDING UNANTICIPATED EVENTS, THAT MAY HAVE OCCURRED OR THAT MAY OCCUR AFTER THE PREPARATION OF THESE FINANCIAL PROJECTIONS, EVEN IN THE EVENT THAT ANY OR ALL OF THE ASSUMPTIONS UNDERLYING THE FINANCIAL PROJECTIONS ARE SHOWN TO BE IN ERROR OR CHANGE.

It is a requirement under the Nasdaq listing requirements that any business acquired by KVSB have a fair market value equal to at least 80% of the balance of the funds in the trust account at the time of the execution of a definitive agreement for an initial business combination. Based on the pre-money valuation of $3.5 billion for Nextdoor compared to the $416.3 million in the trust account, the KVSB board of directors determined that this requirement was met. The KVSB Board determined that the consideration being paid in the Business Combination, which amount was negotiated at arms-length, were fair to and in the best interests of KVSB and its stockholders and appropriately reflected Nextdoor's value. In reaching this determination, the KVSB Board concluded that it was appropriate to base such valuation in part on qualitative factors such as management strength and depth, competitive positioning, customer relationships, and technical skills, as well as quantitative factors such as its potential for future growth in revenue and profits. The KVSB Board believes that the financial skills and background of its members qualify it to conclude that the acquisition of Nextdoor met this requirement.

of its remaining stockholders and its board of directors, dissolving and liquidating, subject in each case to its obligations under the DGCL to provide for claims of creditors and the requirements of other applicable law. In such event, the 10,000,000 founder shares owned by the Sponsor and KVSB's independent directors would be worthless because following the redemption of the public shares, KVSB would likely have few, if any, net assets and because the Sponsor and KVSB's directors and officers have agreed to waive their respective rights to liquidating distributions from the trust account in respect of the 10,000,000 founder shares held by them if KVSB fails to complete a business combination within the required period. Additionally, in such event, the 1,132,688 private placement shares purchased by the Sponsor simultaneously with the consummation of the initial public offering for an aggregate purchase price of $11.3 million, will also expire worthless. Mr. Kaul, KVSB's Chairman and Chief Executive Officer, also has an economic interest in such private placement shares and in the 9,880,000 founder shares owned by the Sponsor. The 10,232,269 shares of New Nextdoor Class B common stock into which the 9,880,000 founder shares held by the Sponsor will automatically convert and be exchanged in connection with the Merger, if unrestricted, fully vested and freely tradable, would have had an aggregate market value of approximately $ million based upon the closing price of $ per share on Nasdaq on 2021, the most recent practicable date prior to the date of this proxy statement/prospectus. However, given that such shares of New Nextdoor Class B common stock will be subject to certain lock-up restrictions, KVSB believes such shares may have less value. The 176,334 shares of New Nextdoor Class B common stock into which the 120,000 founder shares held by KVSB's independent directors will automatically convert and be exchanged in connection with the Merger, if unrestricted and freely tradable, would have had an aggregate market value of approximately $ million based upon the closing price of $ per share on the Nasdaq on , 2021, the most recent practicable date prior to the date of this proxy statement/prospectus. The 1,132,688 shares of New Nextdoor Class B common stock representing the 1,132,688 private placement shares held by the Sponsor (after exchange), if unrestricted and freely tradable, would have had an aggregate market value of approximately $ million based upon the closing price of $ per share on the Nasdaq on 2021, the most recent practicable date prior to the date of this proxy statement/prospectus. The Sponsor Related PIPE Investors have subscribed for $7,500,000 of the PIPE Investment, for which they will receive 750,000 shares of New Nextdoor Class A common stock, which, if unrestricted and freely tradable, would have had an aggregate market value of approximately $ million based upon the closing price of $ per share on Nasdaq on , 2021, the most recent practicable date prior to the date of this proxy statement/prospectus. Based on the difference in the purchase price of $0.0025 that the Sponsor paid for the founder shares, as compared to the purchase price of $10.00 per share of KVSB Class A common stock sold in the initial public offering, the Sponsor and its affiliates may earn a positive rate of return on their investment even if the share price of New Nextdoor Class A common stock after the Closing falls below the price initially paid for the KVSB Class A common stock in the initial public offering and the public stockholders experience a negative rate of return on their investment following the Closing of the Business Combination.

119

These conflicts may not be resolved in KVSB's favor and such potential business opportunities may be presented to other entities prior to their presentation to KVSB, subject to applicable fiduciary duties under the DGCL. KVSB's Existing Organizational Documents provide that KVSB renounces its interest in any corporate opportunity offered to any director or officer of KVSB.

•KVSB's officers and directors and their affiliates are entitled to reimbursement of out-of-pocket expenses incurred by them in connection with certain activities on KVSB's behalf, such as identifying and investigating possible business targets and business combinations. KVSB expects to incur approximately $28.3 million of transaction expenses (excluding the deferred underwriting commissions being held in the trust account), and to the extent that KVSB's officers and directors or their affiliates are advancing any of these expenses on behalf of KVSB, they are entitled to reimbursement of such payments. However, if KVSB fails to consummate a business combination by the Liquidation Date, they will not have any claim against the trust account for reimbursement. Accordingly, KVSB may not be able to reimburse the expenses advanced by KVSB's officers and directors or their affiliates if the Business Combination, or another business combination, is not completed by the Liquidation Date.

(including KVSB's independent directors) owns issued and outstanding shares of KVSB common stock representing 16.9% of the outstanding voting power on an as-converted basis, and 12.8% of the outstanding voting power on a per actual share basis.

Interests of Nextdoor's Directors and Executive Officers in the Business Combination

Sarah Friar. Ms. Friar, Nextdoor's Chief Executive Officer and President, has agreed to subscribe for and purchase 500,000 shares of New Nextdoor Class A common stock at $10.00 per share in the PIPE Investment on the same terms and conditions as the other PIPE Investors, for aggregate proceeds of $5,000,000. Such shares of New Nextdoor Class A common stock would have had an estimated aggregate value of $ based on the closing price of $ per public share on Nasdaq on , 2021, the closing price on the record date. In addition, in March 2021, Ms. Friar was granted a stock option to purchase 743,184 shares of Nextdoor common stock, with an aggregate grant date fair value of $8,513,428, which will vest upon closing of the Business Combination, subject to Ms. Friar's continued employment through such date.

121

Severance Agreements. Prior to the Business Combination it is expected that New Nextdoor will enter into Severance Agreements with the current executive officers of Nextdoor. Under each Severance Agreement, the applicable executive officer who is terminated by New Nextdoor without cause or who resigns for good reason outside of a change in control (each such term as defined in each Severance Agreement) will receive, in exchange for a customary release of claims: (i) a severance payment of six months base salary in lump sum and (ii) payment of premiums for continued medical benefits for up to six months following termination. In addition, if an executive officer's employment is terminated by us without cause or by an executive for good reason within the three months preceding a change in control (but after a legally binding and definitive agreement for a potential change of control has been executed) or within the twelve months following a change in control, the Severance Agreements provide the following benefits in exchange for a customary release of claims: (i) a severance payment of twelve months' base salary and then-current target bonus opportunity at 100% achievement of target paid in a cash lump sum, (ii) full acceleration of time-vesting equity awards and accelerated vesting of performance-vesting equity awards at the greater of (x) actual performance through the date of termination or (y) target level (unless an individual equity award agreement provides otherwise), and (iii) payment of premiums for continued medical benefits for up to twelve months following termination. See the section entitled 'Management of New Nextdoor Following the Business Combination - Executive Offer Letters - Severance Agreements' for further discussion.

Expected Accounting Treatment of the Transactions

Nextdoor has been determined to be the accounting acquirer based on the evaluation of the following facts and circumstances under both the no and maximum redemption scenarios:

•Nextdoor stockholders will have a relative majority of the voting power of New Nextdoor;

•The board of directors of New Nextdoor will have ten members, and Nextdoor stockholders will have the ability to nominate a majority of the members of the board of directors;

•Nextdoor's senior management will comprise the senior management roles of New Nextdoor and be responsible for the day-to-day operations;

•New Nextdoor will assume the Nextdoor Holdings, Inc. name and corporate headquarters; and

•The intended strategy and operations of New Nextdoor will continue Nextdoor's current strategy and operations to leverage technology to connect millions of neighbors online and in real life to build stronger, more vibrant, and resilient neighborhoods.

Vote Required for Approval

The approval of the BCA Proposal requires the affirmative vote of holders of a majority of the shares of KVSB Class A common stock and KVSB Class B common stock that are voted at the special meeting. An abstention will be counted towards the quorum requirement but will not count as a vote cast at the special meeting. A broker non-vote will not be counted towards the quorum requirement, as we believe all proposals presented to the stockholders will be considered non-discretionary, or count as a vote cast at the special meeting.

All other proposals, including the Condition Precedent Proposals, require the affirmative vote of the holders of a majority of the votes cast by holders of shares of KVSB Class A common stock and KVSB Class B common stock represented in person or by proxy and entitled to vote thereon, voting together as a single class, other than in the case of the Charter Proposal, which requires (1) the affirmative vote of holders of a majority of the voting power of the outstanding shares of KVSB Class A common stock and KVSB Class B common stock, voting together as a single class, (2) the affirmative vote or written consent of the holders of a majority of the voting power of the

122

outstanding shares of KVSB Class K common stock, voting separately as a series (which consent has already been obtained prior to the special meeting) and (3) the affirmative vote or written consent of the holders of a majority of the voting power of the outstanding shares of KVSB Class B common stock, voting separately as a series.

The BCA Proposal is conditioned on the approval of each of the Condition Precedent Proposals. Therefore, if any of the Condition Precedent Proposals is not approved, the BCA Proposal will have no effect, even if approved by requisite holders of KVSB common stock.

Recommendation of KVSB's Board of Directors

THE KVSB BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE KVSB STOCKHOLDERS VOTE 'FOR' THE APPROVAL OF THE BCA PROPOSAL.

The Proposed Charter provides that any amendment to New Nextdoor's bylaws will require the approval of either a majority of the New Nextdoor board of directors or the holders of at least two-thirds of New Nextdoor's then-outstanding shares of capital stock entitled to vote in an election of directors, voting together as a single class; providedthat, in the case any amendment is approved by at least two-thirds of the board of directors, then the amendment will require only the affirmative vote of the holders of a majority of the then-outstanding shares of the capital stock entitled to vote in an election of directors, voting together as a single class.

127



Provisions Specific to a Blank Check Company	The Existing Charter prohibits KVSB from entering into an 'initial business combination' with another blank check company or similar company with nominal operations.	The Proposed Charter will not include this blank check company provision because the terms governing KVSB's consummation of an initial business combination will not be applicable following consummation of the Business Combination.

Reasons for the Amendments to the Existing Charter

Name Change

Changing the post-combination corporate name from 'Khosla Ventures Acquisition Co. II' to 'Nextdoor Holdings, Inc.' is desirable to reflect the Business Combination with Nextdoor and to clearly identify New Nextdoor as the publicly traded entity. Additionally, the KVSB Board believes the name of the post-combination company should more closely align with the name of the existing operating business of Nextdoor.

Authorized Shares of Common Stock

The greater number of authorized shares of New Nextdoor will be used to issue shares to the PIPE Investors and to employees of New Nextdoor under the 2021 Plan and the ESPP, each as proposed to be adopted by KVSB in connection with the Business Combination, and for general corporate purposes. Additionally, the KVSB Board believes that it is important for New Nextdoor to have available for issuance a number of authorized shares of common stock and preferred stock sufficient to support New Nextdoor's growth and to provide flexibility for future corporate needs (including, if needed, as part of financing for future growth acquisitions).

Notwithstanding the foregoing, authorized but unissued shares of common stock may enable the New Nextdoor board of directors to render it more difficult or to discourage an attempt to obtain control of New Nextdoor and thereby protect continuity of or entrench its management, which may negatively impact the market price of the common stock. If, in the due exercise of its fiduciary obligations, for example, the New Nextdoor board of directors were to determine that a takeover proposal was not in the best interests of New Nextdoor, such shares could be issued by the board of directors without stockholder approval in one or more private placements or other transactions that might prevent or render more difficult or make more costly the completion of any attempted takeover transaction by diluting voting or other rights of the proposed acquirer or insurgent stockholder group, by creating a substantial voting bloc in institutional or other hands that might support the position of the incumbent board of directors, by effecting an acquisition that might complicate or preclude the takeover, or otherwise. The authorization of additional shares will, however, enable New Nextdoor to have the flexibility to authorize the issuance of shares in the future for financing its business, for acquiring other businesses, for forming strategic partnerships and alliances and for stock dividends and stock splits. New Nextdoor currently has no such plans, proposals, or arrangements, written or otherwise, to issue any of the additional authorized shares for such purposes.

Rights of Common Stock

Under the Existing Charter, immediately after the Closing, (A) all outstanding shares of KVSB Class B common stock are automatically convertible into an amount of shares of KVSB Class A common stock equal to (i) the quotient of (x) the Outstanding Shares divided by (y) one minus the Applicable Percentage, minus (ii) the Outstanding Shares and (B) only to the extent that certain triggering events occur prior to the 10th anniversary of the Business Combination, certain outstanding shares of KVSB Class K common stock automatically convert into an amount of shares of KVSB Class A common stock equal to (i) the quotient of (x) the Outstanding Shares divided by (y) one minus the Applicable Percentage, minus (ii) the sum of (x) Outstanding Shares and (y) the number of shares of KVSB Class A common stock issued upon conversion of the KVSB Class B common stock and KVSB Class K common stock (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like). Notwithstanding the foregoing, the Merger Agreement and the Proposed Charter provide that each outstanding share of KVSB Class B common stock and KVSB Class K common stock will convert into 10,408,603 shares of New Nextdoor Class B common stock immediately following the Closing.

128

The Proposed Charter provides that (i) each holder of New Nextdoor Class A common stock shall have the right to one vote per share of New Nextdoor Class A common stock held of record by such holder and (ii) each holder of New Nextdoor Class B common stock shall have the right to ten votes per share of New Nextdoor Class B common stock held of record by such holder. Because upon consummation of the Business Combination, the Sponsor and current holders of Nextdoor common stock (including holders of Nextdoor equity awards outstanding as of the Closing) will beneficially own all outstanding shares of New Nextdoor Class B common stock, this dual class stock structure provides such holders of New Nextdoor Class B common stock with the ability to influence the outcome of matters requiring stockholder approval. The KVSB board of directors believes the success of New Nextdoor rests on the ability to undertake a long-term view and the experience, industry knowledge and significant interest of the holders of New Nextdoor Class B common stock will enhance New Nextdoor's ability to focus on long-term value creation and help insulate New Nextdoor from short-term outside influences. The voting power of the holders of Next Nextdoor's Class B common stock also provides New Nextdoor with flexibility to employ various financing and transaction strategies involving the issuance of equity securities, while maintaining such holders' control. The Proposed Charter will provide that New Nextdoor Class B common stock will be convertible into shares of New Nextdoor Class A common stock at any time upon election of the holder thereof and provide that the New Nextdoor Class B common stock will convert automatically upon certain transfers and upon the earlier of (i) the date specified by a vote of the holders of two-thirds of the then outstanding shares of New Nextdoor Class B common stock and (ii) ten years from the date of the Closing. Except the voting and conversion rights described above, the holders of New Nextdoor Class A common stock and Class B common stock shall be identical, including with respect to dividends and rights to receive liquidation distributions.

Blank Check Preferred Stock

The KVSB Board believes that these shares of 'blank check' preferred stock will provide New Nextdoor with needed flexibility to issue shares in the future in a timely manner and under circumstances it considers favorable without incurring the risk, delay and potential expense incident to obtaining stockholder approval for a particular issuance.

Notwithstanding the foregoing, authorized but unissued preferred stock may enable the New Nextdoor board of directors to render it more difficult or to discourage an attempt to obtain control of New Nextdoor and thereby protect continuity of or entrench its management, which may negatively impact the market price of the common stock of New Nextdoor. If, in the due exercise of its fiduciary obligations, for example, the New Nextdoor board of directors was to determine that a takeover proposal was not in the best interests of New Nextdoor, such preferred stock could be issued by the New Nextdoor board of directors without stockholder approval in one or more private placements or other transactions that might prevent or render more difficult or make more costly the completion of any attempted takeover transaction by diluting voting or other rights of the proposed acquirer or insurgent stockholder group, by creating a substantial voting bloc in institutional or other hands that might support the position of the incumbent board of directors, by effecting an acquisition that might complicate or preclude the takeover, or otherwise. Allowing the New Nextdoor board of directors to issue the authorized preferred stock on its own volition will enable New Nextdoor to have the flexibility to issue such preferred stock in the future for financing its business, for acquiring other businesses, for forming strategic partnerships and alliances and for stock dividends and stock splits. However, New Nextdoor currently has no such plans, proposals, or arrangements, written or otherwise, to issue any of the additional authorized stock for such purposes.

Actions by Stockholders Amendment

The complete elimination of stockholder written consents prevent a controlling stockholder or group of stockholders from amending the Proposed Charter or bylaws of New Nextdoor or removing directors without calling a special meeting of the stockholders and waiting the notice periods determined by the New Nextdoor board of directors pursuant to the bylaws prior to taking any such action. This guarantees that stockholders are given sufficient time to weigh the arguments presented by both sides in connection with any contested stockholder vote. The KVSB Board believes that a meeting of stockholders, which provides all stockholders an opportunity to deliberate about a proposed action and vote their shares, is the most appropriate forum for stockholder action. Notwithstanding the foregoing, elimination of such stockholder written consents may lengthen the amount of time

129

required to take stockholder actions since actions by written consent are generally not subject to the minimum notice requirement of a stockholders' meeting.

Corporate Opportunity Amendment

The 'corporate opportunity' doctrine provides that directors and officers of a corporation, as part of their duty of loyalty to the corporation and its stockholders, generally have a fiduciary duty to disclose opportunities to the corporation that are related to its business and are prohibited from pursuing those opportunities unless the corporation determines that it is not going to pursue them. Section 122(17) of the DGCL expressly permits Delaware corporations, such as KVSB, to renounce any interest or expectancy of the corporation in certain business opportunities. The Existing Charter currently provides that certain business opportunities are not subject to the 'corporate opportunity' doctrine. The Proposed Charter will be silent on the issue of the application of the doctrine of corporate opportunity. The removal of the corporate opportunity doctrine provisions will ensure that directors, officers and controlling stockholders will not be able to take advantage of opportunities beneficial to New Nextdoor for themselves without first disclosing the opportunity to the New Nextdoor board of directors and giving the New Nextdoor board of directors the opportunity to decline the opportunity on behalf of New Nextdoor.

Voting Thresholds Amendment

Requiring the approval by affirmative vote of (i) at least two-thirds of the voting power of all of the then outstanding shares of capital stock to amend certain provisions of the Proposed Charter, including provisions relating to the classified board, the size of the New Nextdoor board of directors, removal of directors, special meetings, actions by written consent and designation of our preferred stock (or, in the event two-thirds of the New Nextdoor board of directors has approved such amendment, the affirmative vote of a majority of the voting power of all of the then outstanding shares of capital stock), (ii) at least two-thirds of the voting power of the New Nextdoor Class B common stock to amend certain provisions of the Proposed Charter relating to the New Nextdoor Class B common stock and take certain other actions that impact the New Nextdoor Class B common stock, (iii) holders of at least 75% of the voting power of each of New Nextdoor Class A common stock and New Nextdoor Class B common stock, voting separately by class to amend certain provisions of the Proposed Charter relating to the terms of the New Nextdoor Class A common stock or New Nextdoor Class B common stock and (iv) either a majority of the New Nextdoor board of directors or the holders of at least two-thirds of New Nextdoor's then-outstanding shares of capital stock entitled to vote in an election of directors, voting together as a single class, to amend the New Nextdoor bylaws; provided that, in the case any amendment to the New Nextdoor bylaws that is approved by at least two-thirds of the board of directors, then the amendment will require only the affirmative vote of the holders of a majority of the then-outstanding shares of the capital stock entitled to vote in an election of directors, voting together as a single class, is intended to protect key provisions of the Proposed Charter and the New Nextdoor bylaws, respectively, from arbitrary amendment and to prevent a simple majority of stockholders from taking actions that may be harmful to other stockholders or making changes to provisions that are intended to protect all stockholders.

Provisions Specific to a Blank Check Company

The elimination of certain provisions related to KVSB's status as a blank check company is desirable because these provisions will serve no purpose following the Business Combination. For example, the Proposed Charter does not include the requirement to dissolve New Nextdoor after a certain time period and allows it to continue as a corporate entity with perpetual existence following consummation of the Business Combination. Perpetual existence is the usual period of existence for corporations, and the KVSB Board believes it is the most appropriate period for New Nextdoor. In addition, certain other provisions in the Existing Charter require that proceeds from the initial public offering be held in the trust account until the completion of a business combination or redemption of 100% of the outstanding public shares has occurred. These provisions cease to apply once the Business Combination is consummated and are therefore not included in the Proposed Charter.

Vote Required for Approval

Failure to submit a proxy or to vote in person at the special meeting, an abstention from voting or a broker non-vote will have the same effect as a vote 'AGAINST' the special meeting.

The adoption of the Charter Proposal is conditioned on the approval of the BCA Proposal, the Stock Issuance Proposal, the Equity Incentive Plan Proposal and the ESPP Proposal at the special meeting.

The Closing is conditioned on the approval (or waiver, as applicable) of the BCA Proposal, the Charter Proposal, the Stock Issuance Proposal, the Equity Incentive Plan Proposal and the ESPP Proposal at the special meeting.

The Sponsor has agreed to vote its shares of KVSB capital stock in favor of the Charter Proposal. See the section titled 'BCA Proposal - Related Agreements - Sponsor Support Agreement.'

Recommendation of KVSB's Board of Directors

KVSB'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE 'FOR' THE APPROVAL OF THE CHARTER PROPOSAL.

The existence of financial and personal interests of KVSB's directors may result in a conflict of interest on the part of one or more of the directors between what they may believe is in the best interests of KVSB and its stockholders and what they may believe is best for himself or themselves in determining to recommend that stockholders vote for the proposals. See the section entitled 'BCA Proposal - Interests of KVSB's Directors and Officers in the Business Combination' for a further discussion.

ADVISORY CHARTER AMENDMENT PROPOSALS

Overview

In connection with the Business Combination, KVSB is asking its stockholders to vote upon, on a non-binding advisory basis, proposals to approve certain governance provisions contained in the Proposed Charter. This separate vote is not otherwise required by Delaware law separate and apart from the Charter Proposal but, pursuant to SEC guidance, KVSB is required to submit these provisions to its stockholders separately for approval, allowing stockholders the opportunity to present their separate views on important governance provisions. However, the stockholder votes regarding these proposals are advisory votes, and are not binding on KVSB or the KVSB Board (separate and apart from the approval of the Charter Proposal). In the judgment of the KVSB Board, these provisions are necessary to adequately address the needs of New Nextdoor. Furthermore, the Business Combination is not conditioned on the separate approval of the Advisory Charter Amendment Proposals (separate and apart from approval of the Charter Proposal).

KVSB stockholders will be asked to approve, on a non-binding advisory basis, the following material differences between the Proposed Charter and the Existing Charter, which are being presented in accordance with the requirements of the SEC as seven separate sub-proposals (the 'Advisory Charter Amendment Proposals'):

Advisory Charter Amendment Proposal A- To change KVSB's name to 'Nextdoor Holdings, Inc.';

Advisory Charter Amendment Proposal B- To increase the number of authorized shares of New Nextdoor Class A common stock, New Nextdoor Class B common stock and 'blank check' preferred stock and to eliminate the authorized shares of KVSB Class K common stock;

Advisory Charter Amendment Proposal C- To provide that holders of New Nextdoor Class A common stock will be entitled to one vote per share of New Nextdoor Class A common stock and holders of New Nextdoor Class B common stock will be entitled to ten votes per share of New Nextdoor Class B common stock;

Advisory Charter Amendment Proposal D- To require that stockholders only act at annual and special meeting of the corporation and not by written consent;

Advisory Charter Amendment Proposal E- To eliminate the current limitations in place on the corporate opportunity doctrine;

Advisory Charter Amendment Proposal F- To establish the required vote thresholds for approving amendments to the certificate of incorporation and bylaws at two-thirds; and

Advisory Charter Amendment Proposal G- To establish the required vote thresholds for approving amendments to the Proposed Charter as follows: (i) at least two-thirds of the voting power of all of the then outstanding shares of capital stock will be required to amend certain provisions of the Proposed Charter, including provisions relating to the classified board, the size of the New Nextdoor board of directors, removal of directors, special meetings, actions by written consent and designation of our preferred stock, provided that if two-thirds of the New Nextdoor board of directors has approved such amendment only the affirmative vote of a majority of the voting power of all of the then outstanding shares of capital stock shall be required to amend the Proposed Charter, (ii) at least two-thirds of the voting power of the New Nextdoor Class B common stock will be required to amend certain provisions relating to the New Nextdoor Class B common stock and take certain other actions that impact the New Nextdoor Class B common stock, and (iii) the affirmative vote of holders of at least 75% of the voting power of each of our Class A common stock and Class B common stock, voting separately by class, will be required to amend certain provisions of the Proposed Charter relating to the terms of the New Nextdoor Class A common stock or New Nextdoor Class B common stock.

132

Reasons for the Advisory Charter Amendments

Advisory Charter Amendment Proposal A

Advisory Charter Amendment Proposal B

Under the Existing Charter, upon the Closing, (A) all outstanding shares of KVSB Class B common stock are automatically convertible into an amount of shares of KVSB Class A common stock equal to (i) the quotient of (x) the Outstanding Shares (as defined therein) divided by (y) one minus the Applicable Percentage (as defined therein), minus (ii) the Outstanding Shares and (B) all outstanding shares of KVSB Class K common stock are automatically convertible into an amount of shares of KVSB Class A common stock equal to (i) the quotient of (x) the Outstanding Shares divided by (y) one minus the Applicable Percentage, minus (ii) the sum of (x) Outstanding Shares and (y) the number of shares of KVSB Class A common stock issued upon conversion of the KVSB Class B common stock (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like). As a result, only one class of KVSB common stock would be outstanding upon the closing of the Business Combination. The Merger Agreement provides that each outstanding share of KVSB common stock will be converted and reclassified into the right to receive New Nextdoor common stock.

The KVSB Board believes that authorizing shares of 'blank check' preferred stock will provide New Nextdoor with needed flexibility to issue shares in the future in a timely manner and under circumstances it considers favorable without incurring the risk, delay and potential expense incident to obtaining stockholder approval for a particular issuance.

133

placements or other transactions that might prevent or render more difficult or make more costly the completion of any attempted takeover transaction by diluting voting or other rights of the proposed acquirer or insurgent stockholder group, by creating a substantial voting bloc in institutional or other hands that might support the position of the incumbent board of directors, by effecting an acquisition that might complicate or preclude the takeover, or otherwise. Allowing the New Nextdoor board of directors to issue the authorized preferred stock on its own volition will enable New Nextdoor to have the flexibility to issue such preferred stock in the future for financing its business, for acquiring other businesses, for forming strategic partnerships and alliances and for stock dividends and stock splits. However, New Nextdoor currently has no such plans, proposals, or arrangements, written or otherwise, to issue any of the additional authorized stock for such purposes.

Advisory Charter Amendment Proposal C

Because upon consummation of the Business Combination, current holders of KVSB common stock and Nextdoor common stock will beneficially own all outstanding shares of New Nextdoor Class B common stock, this dual class stock structure provides such holders of New Nextdoor Class B common stock with the ability to influence the outcome of matters requiring stockholder approval. The KVSB board of directors believes the success of New Nextdoor rests on the ability to undertake a long-term view and the experience, industry knowledge and significant interest of the holders of New Nextdoor Class B common stock will enhance New Nextdoor's ability to focus on long-term value creation and help insulate New Nextdoor from short-term outside influences. The voting power of the holders of Next Nextdoor's Class B common stock also provides New Nextdoor with flexibility to employ various financing and transaction strategies involving the issuance of equity securities, while maintaining such holders' control.

Advisory Charter Amendment Proposal D

The elimination of stockholder written consents prevent a controlling stockholder or group of stockholders from amending the Proposed Charter or bylaws of New Nextdoor or removing directors without calling a special meeting of the stockholders and waiting the notice periods determined by the New Nextdoor board of directors pursuant to the bylaws prior to taking any such action. This guarantees that stockholders are given sufficient time to weigh the arguments presented by both sides in connection with any contested stockholder vote. The KVSB Board believes that a meeting of stockholders, which provides all stockholders an opportunity to deliberate about a proposed action and vote their shares, is the most appropriate forum for stockholder action. Notwithstanding the foregoing, elimination of such stockholder written consents may lengthen the amount of time required to take stockholder actions since actions by written consent are generally not subject to the minimum notice requirement of a stockholders' meeting.

Advisory Charter Amendment Proposal E

Advisory Charter Amendment Proposal F

Requiring the approval by affirmative vote of holders of at least two-thirds of the voting power of New Nextdoor's then-outstanding shares of capital stock entitled to vote in an election of directors to make any amendment to (a) certain provisions of the Proposed Charter and (b) New Nextdoor's bylaws not approved by the New Nextdoor board of directors is intended to protect key provisions of the Proposed Charter and the New

134

Nextdoor bylaws, respectively, from arbitrary amendment and to prevent a simple majority of stockholders from taking actions that may be harmful to other stockholders or making changes to provisions that are intended to protect all stockholders.

Advisory Charter Amendment Proposal G

A copy of KVSB's Proposed Charter, as will be in effect assuming approval of the Charter Proposal and upon consummation of the Business Combination and filing with the Delaware Secretary of State, is attached to this proxy statement/prospectus as Annex C.

Vote Required for Approval

The approval of the Advisory Charter Amendment Proposals require the affirmative vote of a majority of the votes cast by holders of shares of KVSB Class A common stock and KVSB Class B common stock represented in person or by proxy and entitled to vote thereon, voting together as a single class. An abstention will be counted towards the quorum requirement but will not count as a vote cast at the special meeting. A broker non-vote will not be counted towards the quorum requirement, as we believe all proposals presented to the stockholders will be considered non-discretionary, or count as a vote cast at the special meeting.

Recommendation of KVSB's Board of Directors

THE BOARD UNANIMOUSLY RECOMMENDS THAT KVSB STOCKHOLDERS VOTE 'FOR' THE APPROVAL OF EACH OF THE ADVISORY CHARTER AMENDMENT PROPOSALS.

The existence of financial and personal interests of one or more of KVSB's directors may result in a conflict of interest on the part of such director(s) between what he or they may believe is in the best interests of KVSB and its stockholders and what he or they may believe is best for himself or themselves in determining to recommend that stockholders vote for the Proposals. In addition, KVSB's directors and officers have interests in the Business Combination that may conflict with your interests as a stockholder. See the section entitled 'BCA Proposal - Interests of the Sponsor and KVSB's Directors and Officers in the Business Combination' for a further discussion of these considerations.

135

STOCK ISSUANCE PROPOSAL

Overview

KVSB is asking its stockholders to consider and vote upon a proposal to approve and adopt, assuming the BCA Proposal and the Charter Proposal are approved, for the purposes of complying with Rule 5635(a), (b) and (d) of the Nasdaq Stock Market Listing Rules, the issuance of shares of New Nextdoor common stock to (a) the PIPE Investors, including the Sponsor Related PIPE Investor and the Nextdoor PIPE Investors, pursuant to the PIPE Investment, (b) the New Nextdoor stockholders pursuant to the Merger Agreement and (c) the Khosla Entities pursuant to the Forward Purchase Agreement (the 'Stock Issuance Proposal').

Reasons for the Approval for Purposes of Nasdaq Rule 5635

Under Nasdaq Rule 5635(a), stockholder approval is required prior to the issuance of securities in connection with the acquisition of another company if such securities are not issued in a public offering and (i) have, or will have upon issuance, voting power equal to or in excess of 20% of the voting power outstanding before the issuance of common stock (or securities convertible into or exercisable for common stock); or (ii) the number of shares of common stock to be issued is or will be equal to or in excess of 20% of the number of shares of common stock outstanding before the issuance of the stock or securities. Collectively, the Aggregate Merger Consideration and the shares being issued to the PIPE Investors will exceed 20% or more of the outstanding shares of KVSB common stock and 20% or more of the voting power, in each case outstanding before the issuance of such shares in connection with the Business Combination and the PIPE Investment.

Under Nasdaq Rule 5635(b), stockholder approval is required when any issuance or potential issuance will result in a 'change of control' of the issuer. Although Nasdaq has not adopted any rule on what constitutes a 'change of control' for purposes of Rule 5635(b), Nasdaq has previously indicated that the acquisition of, or right to acquire, by a single investor or affiliated investor group, as little as 20% of the common stock (or securities convertible into or exercisable for common stock) or voting power of an issuer could constitute a change of control. Under Nasdaq Rule 5635(b), the issuance of the Aggregate Merger Consideration and/or the shares in the PIPE Investment will result in a 'change of control' of KVSB.

Under Nasdaq Listing Rule 5635(d), stockholder approval is required for a transaction other than a public offering involving the sale, issuance or potential issuance by an issuer of common stock (or securities convertible into or exercisable for common stock) at a price that is less than the lower of (i) the closing price immediately preceding the signing of the binding agreement or (ii) the average closing price of the common stock for the five trading days immediately preceding the signing of the binding agreement, if the number of shares of common stock (or securities convertible into or exercisable for common stock) to be issued equals 20% or more of the common stock, or 20% or more of the voting power, outstanding before the issuance. Because shares of New Nextdoor common stock will be issued in exchange for all of the equity interests of Nextdoor, the deemed issuance price of the shares of the New Nextdoor common stock may be less than the lower of (i) the closing price immediately preceding the signing of the Merger Agreement or (ii) the average closing price of KVSB Class A common stock for the five trading days immediately preceding the signing of the Merger Agreement. If the BCA Proposal is approved, the issuance of the shares of New Nextdoor common stock will exceed 20% of the shares of KVSB common stock currently outstanding. Because the issuance price may be deemed to be below the lower of (i) the closing price immediately preceding the signing of the Merger Agreement or (ii) the average closing price of KVSB Class A common stock for the five trading days immediately preceding the signing of the Merger Agreement, the Nasdaq Rules may require that KVSB obtain stockholder approval of the issuance of the shares of New Nextdoor common stock in connection with the consummation of the Business Combination.

In addition, because the shares of KVSB Class A common stock issuable to the PIPE Investors (1) will be issued at a price that is less than the lower of (i) the closing price immediately preceding the signing of the Merger Agreement or (ii) the average closing price of the KVSB Class A common stock for the five trading days immediately preceding the signing of the Merger Agreement, and (2) will constitute more than 20% of the outstanding shares of KVSB common stock and more than 20% of outstanding voting power of KVSB common

136

stock prior to such issuance, KVSB is required to obtain stockholder approval of such issuance pursuant to Nasdaq Rule 5635(d).

As a result of the foregoing, KVSB is required to obtain stockholder approval pursuant to The Nasdaq Stock Market Listing Rule 5635. For a summary of the Subscription Agreements, see the section entitled 'BCA Proposal - Related Agreements - Subscription Agreements.' KVSB stockholders should read carefully this proxy statement/prospectus in its entirety for more detailed information regarding the Subscription Agreements. You are urged to read carefully the form of Subscription Agreement in its entirety before voting on this Proposal.

In the event that this proposal is not approved by KVSB stockholders, the Business Combination cannot be consummated. In the event that this proposal is approved by KVSB stockholders, but the Merger Agreement is terminated (without the Business Combination being consummated) prior to the issuance of shares of New Nextdoor common stock pursuant to the Merger Agreement or the PIPE Investment, such shares of New Nextdoor common stock will not be issued.

Vote Required for Approval

The approval of the Stock Issuance Proposal requires the affirmative vote of the holders of a majority of the votes cast by holders of shares of KVSB Class A common stock and KVSB Class B common stock represented in person or by proxy and entitled to vote thereon, voting together as a single class. An abstention will be counted towards the quorum requirement but will not count as a vote cast at the special meeting. A broker non-vote will not be counted towards the quorum requirement, as we believe all proposals presented to the stockholders will be considered non-discretionary, or count as a vote cast at the special meeting.

The Stock Issuance Proposal is conditioned on the approval of each of the Condition Precedent Proposals. Therefore, if any of the Condition Precedent Proposals is not approved, the Stock Issuance Proposal will have no effect, even if approved by holders of KVSB common stock.

Recommendation of the KVSB Board of Directors

THE KVSB BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT KVSB STOCKHOLDERS VOTE 'FOR' THE APPROVAL OF THE STOCK ISSUANCE PROPOSAL.

EQUITY INCENTIVE PLAN PROPOSAL

Overview

The Equity Incentive Plan Proposal - to consider and vote upon a proposal to approve and adopt by ordinary resolution the Nextdoor, Inc. 2021 Equity Incentive Plan, which is referred to herein as the 'Equity Incentive Plan,' a copy of which is attached to this proxy statement/prospectus as Annex H (such proposal, the 'Equity Incentive Plan Proposal').

A total of shares of New Nextdoor Class A common stock will be reserved for issuance under the Equity Incentive Plan. On , 2021, the closing price on Nasdaq of a share of KVSB Class A common stock was $ . The KVSB Board approved the Equity Incentive Plan on July 5, 2021, subject to approval by KVSB's stockholders. If the Equity Incentive Plan is approved by our stockholders, then the Equity Incentive Plan will be effective upon the consummation of the Business Combination.

The following is a summary of the material features of the Equity Incentive Plan. This summary is qualified in its entirety by the full text of the Equity Incentive Plan, a copy of which is included as Annex H to this proxy statement/prospectus.

Summary of the Nextdoor, Inc. 2021 Equity Incentive Plan

The Equity Incentive Plan was adopted by the KVSB Board prior to the Closing, subject to stockholder approval, and will become effective upon the Closing. The Equity Incentive Plan allows New Nextdoor to grant awards of stock options, restricted stock awards, stock appreciation rights ('SARs'), restricted stock units ('RSUs'), performance awards, and stock bonus awards to eligible officers, employees, directors and consultants. The KVSB Board anticipates that providing such persons with a direct stake in New Nextdoor will assure a closer alignment of the interests of such individuals with those of New Nextdoor and its stockholders, thereby stimulating their efforts on New Nextdoor's behalf and strengthening their desire to remain with New Nextdoor.

Securities to be offered. KVSB has initially reserved shares of New Nextdoor Class A common stock, less any shares subject to outstanding awards granted under the Nextdoor, Inc. 2018 Equity Incentive Plan between the date on which the Business Combination Agreement was executed and the effective date of the Equity Incentive Plan, for issuance pursuant to awards granted under the Equity Incentive Plan (provided that this deduction shall not include any Promised Equity (as defined in the Merger Agreement) that is included in the definition of Aggregate Fully Diluted Company Common Shares (as defined in the Merger Agreement)). The number of shares reserved for issuance under the Equity Incentive Plan will increase automatically on January 1 of each of 2022 through 2031 by the number of shares equal to the lesser of (i) five percent 5% of the total number of outstanding shares (rounded down to the nearest whole share) of Class A and Class B of New Nextdoor common stock as of the immediately preceding December 31, or (ii) a number as may be determined by the New Nextdoor Board. Notwithstanding anything to the contrary in the Equity Incentive Plan, no more than shares of New Nextdoor Class A common stock may be issued pursuant to the exercise of ISOs under the Equity Incentive Plan. In addition, the following shares of New Nextdoor Class A common stock will be available for grant and issuance under the Equity Incentive Plan:

•shares subject to issuance upon exercise of stock options or SARs granted under the Equity Incentive Plan that cease to be subject to the stock option or SAR for any reason other than exercise of the option or SAR;

•shares subject to awards granted under the Equity Incentive Plan that are subsequently forfeited or repurchased at the original issue price;

•shares subject to awards granted under the Equity Incentive Plan that otherwise terminate without shares being issued;

•shares surrendered pursuant to an Exchange Program (as defined in the Equity Incentive Plan);

•shares subject to an award that is paid out in cash or other property, rather than shares;

138

•shares subject to awards under the Equity Incentive Plan that are used to pay the exercise price of an award or withheld to satisfy the tax withholding obligations related to any award;

•shares issuable upon the exercise of stock options or subject to other awards under the Nextdoor, Inc. 2018 Equity Incentive Plan that cease to be subject to such stock options or other awards by forfeiture or otherwise after the effective date of the Equity Incentive Plan without such shares being issued;

•shares subject to outstanding awards under the Nextdoor, Inc. 2018 Equity Incentive Plan that are forfeited or repurchased by us at the original issue price after the effective date of the Equity Incentive Plan; and

•shares subject to awards under the Nextdoor, Inc. 2018 Equity Incentive Plan that are used to pay the exercise price of a stock option or withheld to satisfy the tax withholding obligations related to any award.

The following is a description of the material terms of the Equity Incentive Plan.

The summary below does not contain a complete description of all provisions of the Equity Incentive Plan and is qualified in its entirety by reference to the Equity Incentive Plan, a copy of which is attached to this proxy statement/prospectus as Annex H.

Administration.The Equity Incentive Plan is expected to be administered by New Nextdoor's compensation committee or by the New Nextdoor Board acting in place of the compensation committee and by the New Nextdoor Board with respect to awards granted to non-employee directors. Subject to the terms and conditions of the Equity Incentive Plan, the compensation committee will have the authority, among other things, to select the persons to whom awards may be granted, construe and interpret the Equity Incentive Plan as well as to determine the terms of such awards and prescribe, amend, and rescind the rules and regulations relating to the plan or any award granted thereunder. The Equity Incentive Plan provides that the board of directors or compensation committee may delegate its authority, including the authority to grant awards, to one or more officers to the extent permitted by applicable law, provided that awards granted to non-employee directors may only be determined by the New Nextdoor Board. References to 'compensation committee' below refer to the compensation committee or the New Nextdoor Board, in its capacity as the administrator of the Equity Incentive Plan, as applicable.

Eligibility.The Equity Incentive Plan is expected to provide for the grant of awards to eligible employees, directors, and consultants. No non-employee director may receive awards under the Equity Incentive Plan that, when combined with cash compensation received for service as a non-employee director, exceed $750,000 in value (measured as of the date of grant) in any calendar year; provided, however, that a non-employee director may receive awards under the Equity Incentive Plan that, when combined with cash compensation received for service as a non-employee director, with a value of up to $1,000,000 in value (measured as of the date of grant) in his or her initial year of service. Following the Closing, New Nextdoor is expected to have approximately employees, consultants and directors who will be eligible to receive awards under the Equity Incentive Plan. The compensation committee has the authority to select from among eligible individuals those to whom awards will be granted.

Options.The Equity Incentive Plan is expected to provide for the grant of both incentive stock options intended to qualify under Section 422 of the Code, and non-statutory stock options to purchase shares of New Nextdoor Class A common stock at a stated exercise price. Incentive stock options may only be granted to employees, including officers and directors who are also employees. The exercise price of stock options granted under the Equity Incentive Plan must be at least equal to the fair market value of New Nextdoor Class A common stock on the date of grant. Incentive stock options granted to an individual who holds, directly or by attribution, more than ten percent of the total combined voting power of all classes of New Nextdoor capital stock must have an exercise price of at least 110% of the fair market value of New Nextdoor Class A common stock on the date of grant. Subject to stock splits, dividends, recapitalizations or similar events, no more than shares may be issued pursuant to the exercise of incentive stock options granted under the Equity Incentive Plan.

Options may vest based on service or achievement of performance conditions. The compensation committee may provide for options to be exercised only as they vest or to be immediately exercisable, with any shares issued on exercise being subject to a right of repurchase that lapses as the shares vest. The maximum term of options

139

granted under the Equity Incentive Plan is ten years from the date of grant, except that the maximum permitted term of incentive stock options granted to an individual who holds, directly or by attribution, more than ten percent of the total combined voting power of all classes of New Nextdoor capital stock is five years from the date of grant. Upon exercise of options, the option exercise price must be paid in full either in cash or cash equivalents or in other manners approved by the compensation committee, including by surrender of shares of New Nextdoor Class A common stock that are beneficially owned by the optionee free of restrictions. Subject to applicable law, the exercise price may also be delivered pursuant to a broker assisted or other form of cashless exercise program implemented by New Nextdoor in connection with the Equity Incentive Plan.

Restricted stock awards.An award of restricted stock is an offer to sell shares of common stock subject to restrictions that may lapse based on the satisfaction of service or achievement of performance conditions. The price, if any, of an award of restricted stock will be determined by the compensation committee. Unless otherwise determined by the compensation committee, holders of restricted stock will be entitled to vote and to receive any dividends or stock distributions paid pursuant to any vested shares of restricted stock. Holders of unvested restricted stock will not be entitled to receive any dividends or stock distributions paid with respect to unvested shares of restricted stock, and any such dividends or stock distributions will be accrued and paid only as and when such shares of restricted stock become vested. If any such dividends or distributions are paid in shares of New Nextdoor Class A common stock, the shares will be subject to the same restrictions on transferability and forfeiture as the shares of restricted stock with respect to which they were paid.

Stock appreciation rights ('SARs').A SAR provides for a payment, in cash or shares of New Nextdoor common stock (up to a specified maximum of shares, if determined by the compensation committee), to the holder equal to the fair market value of New Nextdoor Class A common stock on the date of exercise less a pre-determined exercise price per share, multiplied by the number of shares with respect to which the SAR is being exercised. Under the Equity Incentive Plan, the exercise price of a SAR must be at least equal to the fair market value of a share of New Nextdoor common stock on the date of grant. SARs may vest based on service or achievement of performance conditions and may not have a term that is longer than ten years from the date of grant.

Restricted stock units ('RSUs').RSUs represent the right to receive shares of common stock at a specified date in the future, and may be subject to vesting based on service or achievement of performance conditions. Payment of earned RSUs may be made as soon as practicable after the date determined at the time of grant or on a deferred basis in the discretion of the compensation committee, and may be settled in cash, shares of common stock or a combination of both. No RSU may have a term that is longer than ten years from the date of grant.

Performance awards.Performance awards granted pursuant to the Equity Incentive Plan may be in the form of a cash bonus, or an award of performance shares or performance units denominated in shares of New Nextdoor Class A common stock, that may be settled in cash, property or by issuance of those shares subject to the satisfaction or achievement of specified performance conditions.

Stock bonus awards.A stock bonus award provides for payment in the form of cash, shares of New Nextdoor Class A common stock or a combination thereof, based on the fair market value of shares subject to such award as determined by the compensation committee. The awards may be subject to vesting restrictions based on continued service or performance conditions.

Dividend equivalent rights.Dividend equivalent rights may be granted at the discretion of the compensation committee and represent the right to receive the value of dividends, if any, paid with respect of the number of shares of New Nextdoor Class A common stock underlying an award. Dividend equivalent rights will be subject to the same vesting or performance conditions as the underlying award and, subject to the discretion of the compensation committee, may be paid when dividend payments are made to stockholders or paid only at such time as the underlying award has become fully vested. Dividend equivalent rights may be settled in cash, shares, or other property, or a combination of thereof as determined by the compensation committee. No dividend equivalent rights will be granted or paid in respect of options or SARs.

Change of control.The Equity Incentive Plan provides that, in the event of certain corporate transactions (as set forth in the Equity Incentive Plan), including the consummation of a merger or consolidation of New Nextdoor

140

with another corporation, outstanding awards under the Equity Incentive Plan shall be subject to the agreement evidencing the corporate transaction, which need not treat all outstanding awards in an identical manner, and may include one or more of the following actions: (i) the continuation of outstanding awards; (ii) the assumption of outstanding awards by the successor or acquiring entity or its parent; (iii) the substitution of outstanding awards by the successor or acquiring entity or its parent with equivalent awards with substantially the same terms; (iv) the full or partial acceleration of exercisability, vesting, or lapse of forfeiture conditions including any right of New Nextdoor to repurchase shares, and accelerated expiration of the award; or (v) the settlement of the full value of the outstanding awards (whether or not then vested or exercisable) in cash, cash equivalents, or securities of the successor entity with a fair market value equal to the required amount, as determined in accordance with the Equity Incentive Plan, which may be deferred until the date or dates the award would have become exercisable or vested. Notwithstanding the foregoing, upon a corporate transaction, the vesting of all awards granted to New Nextdoor's non-employee directors will accelerate and such awards will become exercisable (to the extent applicable) in full prior to the consummation of a corporate transaction at such times and on such conditions as the compensation committee determines.

Adjustment.In the event of a change in the number or class of outstanding shares of common stock by reason of a stock dividend, extraordinary dividend or distribution, recapitalization, stock split, reverse stock split, subdivision, combination, consolidation, reclassification, spin-off or similar change in New Nextdoor's capital structure, without consideration, appropriate proportional adjustments will be made to (i) the number and class of shares reserved for issuance under the Equity Incentive Plan and the incentive stock option limit; (ii) the exercise prices of outstanding stock options and SARs; and (iii) the number and class of shares subject to outstanding awards.

Clawback; transferability.All awards will be subject to clawback or recoupment pursuant to any compensation clawback or recoupment policy adopted by the New Nextdoor Board, to the extent set forth in such policy or applicable agreement, or as required by law. Except in limited circumstances, awards granted under the Equity Incentive Plan may generally not be transferred in any manner prior to vesting other than by will or by the laws of descent and distribution.

Amendment and termination; Exchange Program.The New Nextdoor Board may amend or terminate the Equity Incentive Plan at any time, subject to stockholder approval as may be required. The Equity Incentive Plan will automatically terminate ten years from the date the KVSB Board adopts the Plan, unless it is terminated earlier by the New Nextdoor Board. No termination or amendment of the Equity Incentive Plan may materially adversely affect any then-outstanding award without the consent of the affected participant, except as is necessary to comply with applicable law. Subject to the foregoing, the compensation committee may at any time increase or decrease the exercise price applicable to outstanding options or SARs or pay cash or issue new awards in exchange for the surrender and cancellation of any, or all, outstanding awards.

Form S-8

Following the consummation of the Business Combination, when permitted by SEC rules, we intend to file with the SEC a registration statement on Form S-8 covering the New Nextdoor Class A common stock issuable under the Equity Incentive Plan.

Certain United States Federal Income Tax Consequences

The following is a general summary under current law of certain U.S. federal income tax consequences related to awards and certain transactions under the Equity Incentive Plan. This summary deals with the general federal income tax principles that apply and is provided only for general information. It does not describe all federal tax consequences under the Equity Incentive Plan, nor does it describe state, local or foreign income tax consequences, federal employment tax consequences or any other tax consequences. This summary is not intended as tax advice to participants, who should consult their own tax advisors.

Incentive Stock Options. No taxable income is generally realized by the optionee upon the grant or exercise of an incentive stock option. If shares of New Nextdoor Class A common stock issued to an optionee pursuant to the exercise of an incentive stock option are sold or transferred after two years from the date of grant and after one year from the date of exercise, then generally (i) upon sale of such shares, any amount realized in excess of the option

141

exercise price (the amount paid for the shares) will be taxed to the optionee as a long-term capital gain, and any loss sustained will be a long-term capital loss, and (ii) New Nextdoor will not be entitled to any deduction for federal income tax purposes; provided that such incentive stock option otherwise meets all of the technical requirements of an incentive stock option. Long-term capital gains recognized by non-corporate U.S. holders may be eligible to be taxed at reduced rates. The deductibility of capital losses is subject to limitations. The exercise of an incentive stock option will give rise to an item of tax preference that may result in alternative minimum tax liability for the optionee.

If shares of New Nextdoor Class A common stock acquired upon the exercise of an incentive stock option are disposed of prior to the expiration of the two-year and one-year holding periods described above (a 'disqualifying disposition'), generally (i) the optionee will realize ordinary income in the year of disposition in an amount equal to the excess (if any) of the fair market value of the shares of New Nextdoor Class A common stock at exercise (or, if less, the amount realized on a sale of such shares of New Nextdoor Class A common stock) over the option exercise price thereof, and (ii) New Nextdoor will be entitled to deduct such amount. Special rules will apply where all or a portion of the exercise price of the incentive stock option is paid by tendering shares of New Nextdoor Class A common stock.

If an incentive stock option is exercised at a time when it no longer qualifies for the tax treatment described above, the option is treated as a non-qualified option. Generally, an incentive stock option will not be eligible for the tax treatment described above if it is exercised more than three months following termination of employment (or one year in the case of termination of employment by reason of disability). In the case of termination of employment by reason of death, the three-month rule does not apply.

Non-Qualified Options.No income is generally realized by the optionee at the time a non-qualified option is granted. Generally (i) at exercise, ordinary income is realized by the optionee in an amount equal to the difference between the option exercise price and the fair market value of the shares of New Nextdoor Class A common stock on the date of exercise, and New Nextdoor receives a tax deduction for the same amount, and (ii) at disposition, appreciation or depreciation after the date of exercise is treated as long-term capital gain or loss if the shares of New Nextdoor Class A common stock have been held for more than one year and short-term capital gain or loss if the shares of New Nextdoor Class A common stock have been held for one year or less. Long-term capital gains recognized by non-corporate U.S. holders may be eligible to be taxed at reduced rates. The deductibility of capital losses is subject to limitations.. Special rules will apply where all or a portion of the exercise price of the non-qualified option is paid by tendering shares of New Nextdoor Class A common stock.

Other Awards.The current federal income tax consequences of other awards authorized under the Equity Incentive Plan generally follow certain basic patterns: (i) stock appreciation rights are taxed and deductible in substantially the same manner as non-qualified options; (ii) nontransferable restricted stock subject to a substantial risk of forfeiture results in income recognition equal to the excess of the fair market value over the price paid, if any, only at the time the restrictions lapse (unless the recipient elects to accelerate recognition as of the date of grant through an effective Section 83(b) election); and (iii) restricted stock units, dividend equivalents and other stock or cash based awards are generally subject to tax at the time of payment. New Nextdoor or our subsidiaries or affiliates generally should be entitled to a federal income tax deduction in an amount equal to the ordinary income recognized by the participant at the time the participant recognizes such income.

Parachute Payments. The vesting of any portion of an award that is accelerated due to the occurrence of a change in control (such as a corporate transaction) or the grant or payment of awards in connection with a change in control, may cause all or a portion of the payments with respect to such accelerated, granted or paid awards to be treated as 'parachute payments' as defined in the Code. Any such parachute payments would be non-deductible to New Nextdoor, in whole or in part, and would subject the recipient to a non-deductible 20% federal excise tax on all or a portion of such payment (in addition to other taxes ordinarily payable)

Section 409A of the Code. Certain types of awards under the Equity Incentive Plan may constitute, or provide for, a deferral of compensation subject to Section 409A of the Code. Unless certain requirements set forth in Section 409A of the Code are complied with, holders of such awards may be taxed earlier than would otherwise be the case (e.g., at the time of vesting instead of the time of payment) and may be subject to an additional 20% penalty tax (and, potentially, certain interest, penalties and additional state taxes). To the extent applicable, the Equity Incentive

142

Plan and awards granted under the Equity Incentive Plan are intended to be structured and interpreted in a manner to either comply with or be exempt from Section 409A of the Code and the Department of Treasury regulations and other interpretive guidance that may be issued under Section 409A of the Code. To the extent determined necessary or appropriate by the Equity Incentive Plan administrator, the Equity Incentive Plan and applicable award agreements may be amended to further comply with Section 409A of the Code or to exempt the applicable awards from Section 409A of the Code.

YOU ARE URGED TO CONSULT YOUR TAX ADVISOR WITH RESPECT TO THE APPLICATION OF U.S. FEDERAL TAX LAWS TO YOUR PARTICULAR SITUATION, AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER THE LAWS OF ANY STATE, LOCAL OR FOREIGN JURISDICTION.

New Equity Incentive Plan Benefits

No awards have been previously granted under the Equity Incentive Plan and no awards have been granted that are contingent on stockholder approval of the Equity Incentive Plan. The awards that are to be granted to any participant or group of participants are indeterminable at the date of this proxy statement/prospectus because participation and the types of awards that may be granted under the Equity Incentive Plan are subject to the discretion of the administrator. Consequently, no new plan benefits table is included in this proxy statement/prospectus.

Vote Required for Approval

The approval of the Equity Incentive Plan Proposal requires the affirmative vote of a majority of the votes cast by holders of shares of KVSB Class A common stock and KVSB Class B common stock represented in person or by proxy and entitled to vote thereon, voting together as a single class. An abstention will be counted towards the quorum requirement but will not count as a vote cast at the special meeting. A broker non-vote will not be counted towards the quorum requirement, as we believe all proposals presented to the stockholders will be considered non-discretionary, or count as a vote cast at the special meeting.

Recommendation of KVSB's Board of Directors

THE KVSB BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE KVSB STOCKHOLDERS VOTE 'FOR' THE APPROVAL OF THE EQUITY INCENTIVE PLAN PROPOSAL.

ESPP PROPOSAL

Overview

The Employee Stock Purchase Plan Proposal- to consider and vote upon a proposal to approve and adopt by ordinary resolution the Nextdoor, Inc. Employee Stock Purchase Plan, which is referred to herein as the 'ESPP,' a copy of which is attached to this proxy statement/prospectus as Annex I (such proposal, the 'Employee Stock Purchase Plan Proposal').

On July 5, 2021, the KVSB Board adopted, subject to the approval of our stockholders, the ESPP. We believe that the adoption of the ESPP will benefit us by providing employees with an opportunity to acquire shares of New Nextdoor Class A common stock and will enable us to attract, retain and motivate valued employees.

A total of shares of New Nextdoor Class A common stock will be reserved for issuance under the ESPP. As of , 2021, the closing price on Nasdaq of a share of KVSB Class A common stock was $ . Based upon a price per share of $ , the maximum aggregate market value of the New Nextdoor Class A common stock that could potentially be issued under the ESPP at Closing is $ .

Summary of the Material Provisions of the ESPP

The following description of certain provisions of the ESPP is intended to be a summary only. The summary is qualified in its entirety by the full text of the ESPP, a copy of which is attached to this proxy statement/prospectus as Annex H. The ESPP includes two components: a Section 423 Component and a Non-Section 423 Component. It is our intention that the Section 423 Component qualify as an 'employee stock purchase plan' under Section 423 of the Code. The Non-Section 423 Component that is not intended to meet the requirements of Section 423 of the Code.

Share reserve.An aggregate of shares of New Nextdoor Class A common stock will be reserved and available for sale under the ESPP. The aggregate number of shares reserved for sale under the ESPP will increase automatically on January 1 of each of 2022 through 2031 by a number of shares equal to the lesser of one percent (1%) of the total number of outstanding shares of New Nextdoor's Class A and Class B common stock (on an as-converted to common stock basis) as of the immediately preceding December 31 or a number of shares as may be determined by the New Nextdoor Board or the compensation committee. The aggregate number of shares issued over the term of the ESPP, subject to adjustments for stock-splits, recapitalizations or similar events, may not exceed .

Administration.The compensation committee will administer the ESPP subject to the terms and conditions of the ESPP. Among other things, the compensation committee will have the authority to determine eligibility for participation in the ESPP, designate separate offerings under the ESPP, designate participating corporations and determining which such corporations will participate in the Section 423 Component or Non-Section 423 Component, and construe, interpret and apply the terms of the ESPP.

Eligibility.Employees eligible to participate in any offering pursuant to the ESPP generally include any employee who is employed by New Nextdoor at the beginning of the applicable offering period. However, any employee who owns (or is deemed to own as a result of attribution) 5% or more of the total combined voting power or value of all classes of New Nextdoor capital stock, or the capital stock of one of New Nextdoor's qualifying subsidiaries in the future, or who will own such amount as a result of participation in the ESPP, will not be eligible to participate in the ESPP. The compensation committee may impose additional restrictions on eligibility from time to time. Following the Closing, New Nextdoor is expected to have approximately employees who will be eligible to participate in the ESPP.

Offering Periods; Enrollment.Under the ESPP, eligible employees will be offered the option to purchase shares of New Nextdoor Class A common stock at a discount over a series of offering periods. Each offering period may itself consist of one or more purchase periods. No offering period may be longer than 27 months and each offering period will be determined by the compensation committee. New participants may enroll by submitting an enrollment form prior to the start of an offering period. Once an employee is enrolled, participation will be

144

automatic in subsequent offering periods. An employee's participation automatically ends upon a termination of employment for any reason, and an employee may withdraw from an offering period at any time without affecting his or her eligibility to participate in future offering periods.

Offerings; Contributions.Under the ESPP, eligible employees will be offered the option to purchase shares of New Nextdoor Class A common stock at a discount over a series of offering periods by accumulating funds through payroll deductions, unless the compensation committee determines that contributions may be made in another form, of between 1% and 15% of the employee's compensation. The purchase price for shares of New Nextdoor Class A common stock purchased under the ESPP will be 85% of the lesser of the fair market value of New Nextdoor Class A common stock on (i) the first business day of the applicable offering period and (ii) the date of purchase. However, no participant may purchase more than 2,500 shares on any one purchase date. The compensation committee, in its discretion, may set a lower maximum amount of shares which may be purchased. In addition, no participant will have the right to purchase our shares in an amount, when aggregated with purchase rights under all of New Nextdoor's employee stock purchase plans that are also in effect in the same calendar year, that has a fair market value of more than $25,000, determined as of the first day of the applicable offering period, for each calendar year in which that right is outstanding.

Subject to certain limitations, the number of shares of New Nextdoor Class A common stock a participant purchases in each offering period is determined by dividing the total amount of payroll deductions withheld from the participant's compensation during the offering period by the purchase price. In general, if an employee ceases to be a participant in the ESPP, the employee's option to purchase shares of New Nextdoor Class A common stock under the ESPP will be automatically terminated, and the amount of the employee's accumulated payroll deductions or other contributions will be refunded without interest.

Adjustments upon recapitalization.If the number or class of outstanding shares of New Nextdoor Class A common stock is changed by a stock dividend, recapitalization, stock split, reverse stock split, subdivision, combination, reclassification, or similar change in our capital structure without consideration, then the compensation committee will proportionately adjust the number and class of New Nextdoor Class A common stock that is available under the ESPP, the purchase price and number of shares any participant has elected to purchase under the ESPP, as well as the maximum number of shares which may be issued to any one participant under the ESPP.

Change of control.If we experience a corporate transaction (as defined in the ESPP), any offering period that commenced prior to the closing of the proposed corporate transaction will be shortened and terminated on a new purchase date. The new purchase date will be on or prior to the closing of the proposed corporate transaction, and the ESPP will then terminate on the closing of the corporate transaction.

Transferability.No participant may assign, transfer, pledge, or otherwise dispose of payroll deductions credited to his or her account or of any rights with regard to an election to purchase shares pursuant to the ESPP, other than by will or the laws of descent or distribution.

Amendment; termination.The compensation committee may amend, suspend, or terminate the ESPP at any time without stockholder consent, except as required by law. The ESPP will continue until the earlier to occur of (i) termination of the ESPP by the board of directors, (ii) issuance of all of the shares of New Nextdoor Class A common stock reserved for issuance under the ESPP, or (iii) the tenth anniversary of the effective date of the ESPP.

New Plan Benefits

Since participation in the ESPP is voluntary and benefits under the ESPP depend on contribution elections and the fair market value of the shares of New Nextdoor Class A common stock on various future dates, the benefits or amounts that will be received by or allocated to any individual or group of individuals under the ESPP in the future are not determinable and no awards have been granted that are contingent on stockholder approval of the ESPP.

Certain Material U.S. Federal Income Tax Consequences

Certain U.S. federal income tax consequences of the ESPP under current federal income tax law are summarized in the following discussion, which deals with the general tax principles applicable to the ESPP. The

145

following is only a summary of the effect of the United States income tax laws, regulations, rulings and decisions now in effect upon an employee and us with respect to an employee's participation in the ESPP. This summary does not purport to be a complete description of all U.S. federal tax implications of participation in the ESPP, nor does it discuss the income or other tax laws of any municipality, state or foreign country in which a participant may reside or otherwise be subject to tax or any employment, estate and gift tax considerations, due to the fact that such considerations may vary depending on individual circumstances and from locality to locality.

Section 423 Component.The Section 423 Component of the ESPP is intended to qualify under the provisions of Section 423 of the Code. A participant in the Section 423 Component of the ESPP generally recognizes no taxable income either as a result of participation in the ESPP or upon exercise of an option to purchase shares of New Nextdoor Class A common stock under the terms of the ESPP. Upon a sale or disposition of the shares purchased under the ESPP, a participant will generally be subject to tax in an amount that depends upon the length of time such shares are held by the participant prior to disposing of them.

If a participant disposes of shares purchased upon exercise of an option granted under the Section 423 Component of the ESPP within two years from the first day of the applicable offering period or within one year from the purchase date, which we refer to as a 'disqualifying disposition,' the participant will generally recognize ordinary income in the year of that disposition equal to the amount by which the fair market value of the shares on the date the shares were purchased exceeds the purchase price, and we will be entitled to a tax deduction for compensation expense in the amount of ordinary income recognized by the participant. The amount of ordinary income will be added to the participant's basis in the shares, and any additional gain or resulting loss recognized on the disposition of the shares will be a long-term or short-term capital gain or loss, depending on how long the shares were held following the date they were purchased by the participant prior to disposing of them. The deductibility of capital losses is subject to limitations. A capital gain or loss will generally be long-term if the participant's holding period is more than one year, or short-term if the participant's holding period is one year or less. Long-term capital gains recognized by non-corporate U.S. holders may be eligible to be taxed at reduced rates. If the shares are sold or otherwise disposed of in a disqualifying disposition but are sold for a price that is less than the purchase price, the participant will recognize ordinary income equal to the excess of the fair market value of the shares on the date of purchase over the purchase price (and we will be entitled to a corresponding deduction), but the participant will be able to report a capital loss equal to the difference between the sale price of the shares and the fair market value of the shares on the date of purchase.

If the participant disposes of shares purchased upon exercise of an option granted under the Section 423 Component of the ESPP at least two years after the first day of the applicable offering period and at least one year after the purchase date, or if the participant dies while holding the shares, the participant (or his or her estate) will recognize ordinary income in the year of disposition equal to the lesser of: (1) the excess of the fair market value of the shares at the time the option was granted over the amount paid and (2) the excess of the amount actually received for the New Nextdoor Class A common stock over the amount paid. The amount of any ordinary income will be added to the participant's basis in the shares, and any additional gain recognized upon the disposition after that basis adjustment will be treated as long-term capital gain. Long-term capital gains recognized by non-corporate U.S. holders may be eligible to be taxed at reduced rates. If the fair market value of the shares on the date of disposition is less than the purchase price, there will be no ordinary income and any loss recognized will be a long-term capital loss. The deductibility of capital losses is subject to limitations.

We are generally entitled to a tax deduction in the year of a disqualifying disposition equal to the amount of ordinary income recognized by the participant as a result of that disposition. In all other cases, we are not allowed a deduction.

Non-Section 423 Component. The Non-Section 423 Component of the ESPP is not intended to comply with Section 423 of the Code. If subject to U.S. tax, a participant in the Non-Section 423 Component of the ESPP generally recognizes income in the same manner in which such participant would recognize income upon the grant and exercise of a non-qualified stock option. No income is generally realized by the optionee at the time a non-qualified option is granted, nor will we be entitled to any deduction at that time. Generally (i) at exercise, ordinary income is realized by the optionee in an amount equal to the difference between the option exercise price and the fair market value of the shares of New Valo common stock on the date of exercise, and we receive a tax deduction for

146

the same amount, and (ii) at disposition, appreciation or depreciation after the date of exercise is treated as either short-term or long-term capital gain or loss depending on how long the shares of common stock have been held.

We will generally be entitled to a tax deduction at the time of exercise in an amount equal to the amount of ordinary income recognized by the participant at such time.

Vote Required for Approval

The approval of the ESPP Proposal requires the affirmative vote of a majority of the votes cast by holders of shares of KVSB Class A common stock and KVSB Class B common stock represented in person or by proxy and entitled to vote thereon, voting together as a single class. An abstention will be counted towards the quorum requirement but will not count as a vote cast at the special meeting. A broker non-vote will not be counted towards the quorum requirement, as we believe all proposals presented to the stockholders will be considered non-discretionary, or count as a vote cast at the special meeting.

Recommendation of KVSB's Board of Directors

THE KVSB BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE KVSB STOCKHOLDERS VOTE 'FOR' THE APPROVAL OF THE ESPP PROPOSAL.

147

ADJOURNMENT PROPOSAL

The Adjournment Proposal allows the KVSB Board to submit a proposal to approve the adjournment of the KVSB special meeting to a later date or dates, if necessary, to permit further solicitation and vote of proxies in the event, based on the tabulated votes, there are not sufficient votes at the time of the special meeting to approve the Condition Precedent Proposals. The purpose of the Adjournment Proposal is to permit further solicitation of proxies and votes and to provide additional time for the Sponsor and KVSB New Nextdoor and their respective stockholders to make purchases of KVSB Class A common stock and KVSB Class B common stock or other arrangements that would increase the likelihood of obtaining a favorable vote on the proposals to be put to the special meeting. See 'BCA Proposal - Interests of KVSB's Directors and Executive Officers in the Business Combination.'

Consequences if the Adjournment Proposal is Not Approved

If the Adjournment Proposal is presented to the special meeting and is not approved by the stockholders, the KVSB Board may not be able to adjourn the special meeting to a later date in the event that, based on the tabulated votes, there are not sufficient votes at the time of the special meeting to approve the Condition Precedent Proposals. In such events, the Business Combination would not be completed.

Vote Required for Approval

The approval of the Adjournment Proposal requires the affirmative vote of a majority of the votes cast by holders of shares of KVSB Class A common stock and KVSB Class B common stock represented in person or by proxy and entitled to vote thereon, voting together as a single class. An abstention will be counted towards the quorum requirement but will not count as a vote cast at the special meeting. A broker non-vote will not be counted towards the quorum requirement, as we believe all proposals presented to the stockholders will be considered non-discretionary, or count as a vote cast at the special meeting.

The Adjournment Proposal is not conditioned upon any other proposal.

Recommendation of the KVSB Board of Directors

U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following discussion does not purport to be a complete analysis or discussion of all potential tax effects relevant to the Business Combination. Stockholders are advised to consult with their own personal tax advisors concerning the specific U.S. federal, state, local, and non-U.S. income and other tax consequences of the Business Combination and related transactions applicable to them.

Material U.S. Federal Income Tax Consequences of the Redemption of KVSB Public Stockholders

The following is a discussion of certain material U.S. federal income tax consequences for holders of shares of KVSB Class A common stock that elect to have their KVSB Class A common stock redeemed for cash if the Business Combination is completed. This discussion applies only to KVSB Class A common stock that is held as a capital asset for U.S. federal income tax purposes. This discussion is a summary only and does not describe all of the tax consequences that may be relevant to holders of shares of KVSB Class A common stock in light of each holder's particular circumstances, including but not limited to the alternative minimum tax, the Medicare tax on certain net investment income and the different consequences that may apply if such a holder is subject to special rules that apply to certain types of investors, including but not limited to:

•financial institutions or financial services entities;

•broker-dealers;

•governments or agencies or instrumentalities thereof;

•regulated investment companies;

•real estate investment trusts;

•expatriates or former long-term residents of the United States;

•individual retirement or other tax-deferred accounts;

•persons owning (actually or constructively) 5% or more of our voting shares;

•insurance companies;

•dealers or traders subject to a mark-to-market method of accounting with respect to their KVSB Class A common stock;

•persons holding KVSB Class A common stock as part of a 'straddle,' constructive sale, hedge, conversion or other integrated transaction or similar transaction;

•persons owning (actually or constructively) any Nextdoor securities;

•U.S. holders (as defined below) whose functional currency is not the U.S. dollar;

•partnerships or other pass-through entities or arrangements for U.S. federal income tax purposes and any beneficial owners of such entities;

•controlled foreign corporations;

•passive foreign investment companies;

•a person required to accelerate the recognition of any item of gross income as a result of such income being recognized on an applicable financial statement;

•the Sponsors and persons related to the Sponsors;

•persons holding founder shares or forward-purchase shares; and

149

•tax-exempt entities.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds KVSB Class A common stock, the U.S. federal income tax treatment of a partner in the partnership will generally depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level. Accordingly, partnerships holding KVSB Class A common stock and partners in such partnerships should consult their own tax advisors about the consequences of the matters discussed below.

This discussion is based on the Code, and administrative pronouncements, judicial decisions and final, temporary and proposed Treasury Regulations as of the date hereof, which are subject to change, possibly on a retroactive basis, and changes to any of which subsequent to the date of this proxy statement/prospectus may affect the tax consequences described herein. This discussion does not address any aspect of state, local or non-U.S. taxation, or any U.S. federal taxes other than income taxes (such as gift and estate taxes).

We have not sought, and will not seek, a ruling from the IRS as to any U.S. federal income tax consequence described herein. The IRS may disagree with the discussion herein, and its determination may be upheld by a court. Moreover, there can be no assurance that future legislation, regulations, administrative rulings or court decisions will not adversely affect the accuracy of the statements in this discussion. Holders of shares of KVSB Class A common stock are urged to consult their tax advisor with respect to the application of U.S. federal tax laws to their particular situation, as well as any tax consequences arising under the laws of any state, local or foreign jurisdiction.

U.S. Holders

For purposes of this discussion, the term 'U.S. holder' means a beneficial owner of KVSB Class A common stock who or that is, for U.S. federal income tax purposes:

•an individual who is a citizen or resident of the United States;

•a corporation (or other entity taxable as a corporation) organized in or under the laws of the United States, any state thereof or the District of Columbia;

•an estate the income of which is included in gross income for U.S. federal income tax purposes regardless of its source; or

•a trust, if (i) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more 'United States persons' (as defined in the Code) have authority to control all substantial decisions of the trust or (ii) it has a valid election in effect under the Treasury regulations to be treated as a United States person.

In the event that a U.S. holder's KVSB Class A common stock is redeemed pursuant to the redemption provisions described in this proxy statement/prospectus above, the treatment of the redemption for U.S. federal income tax purposes will depend on whether the redemption qualifies as a sale of such holder's KVSB Class A common stock under Section 302 of the Code. If the redemption qualifies as a sale of KVSB Class A common stock, the U.S. holder will be treated as described under 'U.S. Holders - Taxation of Redemption Treated as a Sale of KVSB Class A Common Stock' below. If the redemption does not qualify as a sale of KVSB Class A common stock, the U.S. holder will be treated as receiving a corporate distribution with the tax consequences described below under 'U.S. Holders - Taxation of Redemption Treated as a Distribution.' Whether a redemption qualifies for sale treatment will depend largely on the total number of shares of our stock treated as held by the U.S. holder relative to all of our shares outstanding both before and after the redemption. The redemption of KVSB Class A common stock generally will be treated as a sale of KVSB Class A common stock (rather than as a corporate distribution) if the redemption (i) is 'substantially disproportionate' with respect to the U.S. holder, (ii) results in a 'complete termination' of the U.S. holder's interest in us or (iii) is 'not essentially equivalent to a dividend' with respect to the U.S. holder. These tests are explained more fully below.

In determining whether any of the foregoing tests are satisfied, a U.S. holder takes into account not only stock actually owned by the U.S. holder, but also shares of our stock that are constructively owned by it. A U.S. holder

150

may constructively own, in addition to stock owned directly, stock owned by certain related individuals and entities in which the U.S. holder has an interest or that have an interest in such U.S. holder, as well as any stock the U.S. holder has a right to acquire by exercise of an option. In order to meet the substantially disproportionate test, the percentage of our outstanding voting stock actually and constructively owned by the U.S. holder immediately following the redemption of its KVSB Class A common stock must, among other requirements, be less than 80% of the percentage of our outstanding voting stock actually and constructively owned by the U.S. holder immediately before the redemption. There will be a complete termination of a U.S. holder's interest if either (i) all of the shares of our stock actually and constructively owned by the U.S. holder are redeemed or (ii) all of the shares of our stock actually owned by the U.S. holder are redeemed and the U.S. holder is eligible to waive, and effectively waives in accordance with specific rules, the attribution of stock owned by certain family members and the U.S. holder does not constructively own any other shares of our stock. The redemption of KVSB Class A common stock will not be essentially equivalent to a dividend if the redemption results in a 'meaningful reduction' of the U.S. holder's proportionate interest in us. Whether the redemption will result in a meaningful reduction in a U.S. holder's proportionate interest in us will depend on the particular facts and circumstances. However, the IRS has indicated in a published ruling that even a small reduction in the proportionate interest of a small minority stockholder in a publicly held corporation who exercises no control over corporate affairs may constitute such a 'meaningful reduction.' The application of these tests generally also takes into account related transactions that occur contemporaneously with the redemption, including any contemporaneous purchases of common stock by the relevant holder (or persons whose ownership is attributed to such holder) and issuances of common stock (including pursuant to the Forward Purchase and PIPE Investment). A U.S. holder should consult with its own tax advisors as to the tax consequences of a redemption.

If none of the foregoing tests is satisfied, then the redemption will be treated as a corporate distribution and the tax effects will be as described under 'U.S. Holders - Taxation of Redemption Treated as a Distribution' below. After the application of those rules, any remaining tax basis of the U.S. holder in the redeemed KVSB Class A common stock will be added to the U.S. holder's adjusted tax basis in its remaining stock, or, if it has none, possibly to the U.S. holder's adjusted tax basis in other stock constructively owned by it.

U.S. Holders-Taxation of Redemption Treated as a Sale of KVSB Class A Common Stock

If the redemption of a U.S. holder's shares of KVSB Class A common stock is treated as a sale, a U.S. holder generally will recognize capital gain or loss in an amount equal to the difference between the amount realized and the U.S. holder's adjusted tax basis in the KVSB Class A common stock treated as sold. Any such capital gain or loss generally will be long-term capital gain or loss if the U.S. holder's holding period for the KVSB Class A common stock so disposed of exceeds one year. It is unclear, however, whether the redemption rights with respect to the KVSB Class A common stock described in this proxy statement/prospectus may suspend the running of the applicable holding period for this purpose. If the running of the holding period for the KVSB Class A common stock is suspended, then non-corporate U.S. holders may not be able to satisfy the one-year holding period requirement for long-term capital gain treatment, in which case any gain on a redemption of the shares would be subject to short-term capital gain treatment and would be taxed at regular ordinary income tax rates. Long-term capital gains recognized by non-corporate U.S. holders may be eligible to be taxed at reduced rates. The deductibility of capital losses is subject to limitations.

Generally, the amount of gain or loss recognized by a U.S. holder is an amount equal to the difference between (i) the amount of cash received in the redemption and (ii) the U.S. holder's adjusted tax basis in its KVSB Class A common stock so redeemed. A U.S. holder's adjusted tax basis in its KVSB Class A common stock generally will equal the U.S. holder's acquisition cost. Gain or loss is calculated separately with respect to each block of stock. A block of stock is stock of the same class acquired for the same price on the same day.

U.S. Holders-Taxation of Redemption Treated as a Distribution

If the redemption of a U.S. holder's shares of KVSB Class A common stock is treated as a distribution, such distribution generally will constitute a dividend for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles.

151

Distributions in excess of current and accumulated earnings and profits will constitute a return of capital that will be applied against and reduce (but not below zero) the U.S. holder's adjusted tax basis in its KVSB Class A common stock. Any remaining excess will be treated as gain realized on the sale or other disposition of KVSB Class A common stock and will be treated as described under 'U.S. Holders - Taxation of Redemption Treated as a Sale of KVSB Class A Common Stock' above. Dividends received by a U.S. holder that is a taxable corporation generally will qualify for the dividends received deduction if the requisite holding period is satisfied. With certain exceptions (including, but not limited to, dividends treated as investment income for purposes of investment interest deduction limitations), and provided certain holding period requirements are met, dividends received by a non-corporate U.S. holder may constitute 'qualified dividends' that will be subject to tax at the maximum tax rate accorded to long-term capital gains. It is unclear whether the redemption rights with respect to the KVSB Class A common stock described in this proxy statement/prospectus may prevent a U.S. holder from satisfying the applicable holding period requirements with respect to the dividends received deduction or the preferential tax rate on qualified dividend income, as the case may be. If the holding period requirements are not satisfied, then a corporation may not be able to qualify for the dividends received deduction and would have taxable income equal to the entire dividend amount, and non-corporate U.S. holders may be subject to tax on such dividend at regular ordinary income tax rates instead of the preferential rate that applies to qualified dividend income.

Information Reporting and Backup Withholding.

In general, information reporting requirements may apply to the proceeds of the redemption of the KVSB Class A common stock, unless the U.S. holder is an exempt recipient. Backup withholding may apply to such payments if the U.S. holder fails to provide a taxpayer identification number or a certification of exempt status or has been notified by the IRS that it is subject to backup withholding (and such notification has not been withdrawn).

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a U.S. holder's U.S. federal income tax liability provided the required information is timely furnished to the IRS.

Non-U.S. Holders

This section applies to you if you are a 'Non-U.S. holder' with respect to KVSB Class A common stock. As used herein, the term 'Non-U.S. holder' means a beneficial owner of KVSB Class A common stock who or that is for U.S. federal income tax purposes:

•a non-resident alien individual (other than certain former citizens and residents of the United States subject to U.S. tax as expatriates);

•a corporation (or other entity taxable as a corporation) that is not organized in or under the laws of the United States, any state thereof or the District of Columbia; or

•an estate or trust that is not a U.S. holder;

but generally does not include an individual who is present in the United States for 183 days or more in the taxable year of disposition of the KVSB Class A common stock. If you are such an individual, you should consult your tax advisor regarding the U.S. federal income tax consequences of redeeming your KVSB Class A common stock.

The characterization for U.S. federal income tax purposes of the redemption of a Non-U.S. holder's KVSB Class A common stock pursuant to the redemption provisions described in this proxy statement/prospectus under the section entitled 'Special Meeting of KVSB - Redemption Rights' generally will correspond to the U.S. federal income tax characterization of such a redemption of a U.S. holder's KVSB Class A common stock, as described under 'U.S. Holders' above, and the consequences of the redemption to the Non-U.S. holder will be as described below under 'Non-U.S. Holders - Taxation of Redemption Treated as a Sale of KVSB Class A Common Stock' and 'Non-U.S. Holders - Taxation of Redemption Treated as a Distribution,' as applicable. It is possible that because the applicable withholding agent may not be able to determine the proper characterization of a redemption of a Non-

152

U.S. holder's KVSB Class A common stock, the withholding agent might treat the redemption as a distribution subject to withholding tax, as discussed further below.

Non-U.S. Holders-Taxation of Redemption Treated as a Sale of KVSB Class A Common Stock

If KVSB's redemption of a Non-U.S. holder's shares of KVSB Class A common stock is treated as a sale, a Non-U.S. holder generally will not be subject to U.S. federal income or withholding tax in respect of gain recognized in connection with such redemption, unless:

•the gain is effectively connected with the conduct of a trade or business by the Non-U.S. holder within the United States (and, under certain income tax treaties, is attributable to a United States permanent establishment or fixed base maintained by the Non-U.S. holder); or

•we are or have been a 'United States real property holding corporation' for U.S. federal income tax purposes at any time during the shorter of the five-year period ending on the date of disposition or the period that the Non-U.S. holder held the KVSB Class A common stock, and, in the case where shares of KVSB Class A common stock are regularly traded on an established securities market, the Non-U.S. holder has owned, directly or constructively, more than 5% of the KVSB Class A common stock at any time within the shorter of the five-year period preceding the disposition or such Non-U.S. holder's holding period for the shares of KVSB Class A common stock. There can be no assurance that the KVSB Class A common stock will be treated as regularly traded on an established securities market for this purpose.

Unless an applicable treaty provides otherwise, gain described in the first bullet point above will be subject to tax at generally applicable U.S. federal income tax rates as if the Non-U.S. holder were a U.S. resident. Any gains described in the first bullet point above of a Non-U.S. holder that is a corporation for U.S. federal income tax purposes may also be subject to an additional 'branch profits tax' imposed at a 30% rate (or lower applicable treaty rate).

If the second bullet point above applies to a Non-U.S. holder, gain recognized by such holder in connection with a redemption treated as a sale of KVSB Class A common stock will be subject to tax at generally applicable U.S. federal income tax rates. In addition, we may be required to withhold U.S. federal income tax at a rate of 15% of the amount realized upon such redemption. We do not believe we currently are or have been at any time since our formation a U.S. real property holding corporation and we do not expect to be a U.S. real property holding corporation immediately after the business combination is completed. However, such determination is factual in nature, and no assurance can be provided that we will not be treated as a U.S. real property holding corporation in a future period.

Non-U.S. Holders-Taxation of Redemption Treated as a Distribution

If the redemption of a Non-U.S. holder's shares of KVSB Class A common stock is treated as a distribution, such a distribution, to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles), generally will constitute a dividend for U.S. federal income tax purposes and, provided such dividend is not effectively connected with the Non-U.S. holder's conduct of a trade or business within the United States, the gross amount of the dividend will be subject to withholding tax at a rate of 30%, unless such Non-U.S. holder is eligible for a reduced rate of withholding tax under an applicable income tax treaty and provides proper certification of its eligibility for such reduced rate (usually on an IRS Form W-8BEN or W-8BEN-E). Any distribution not constituting a dividend will be treated first as reducing (but not below zero) the Non-U.S. holder's adjusted tax basis in its shares of KVSB Class A common stock and, to the extent such distribution exceeds the Non-U.S. holder's adjusted tax basis, as gain realized from the sale or other disposition of KVSB Class A common stock, which will be treated as described under 'Non-U.S. Holders - Taxation of Redemption Treated as a Sale of KVSB Class A Common Stock' above.

The withholding tax generally does not apply to dividends paid to a Non-U.S. holder who provides an IRS Form W-8ECI, certifying that the dividends are effectively connected with the Non-U.S. holder's conduct of a trade or business within the United States. Instead, the effectively connected dividends will be subject to regular U.S. federal income tax as if the Non-U.S. holder were a U.S. resident, subject to an applicable income tax treaty providing

153

otherwise. A Non-U.S. holder that is a corporation for U.S. federal income tax purposes receiving effectively connected dividends may also be subject to an additional 'branch profits tax' imposed at a rate of 30% (or a lower applicable treaty rate).

Because it may not be certain at the time a Non-U.S. holder is redeemed whether such Non-U.S. holder's redemption will be treated as a sale or a corporate distribution, and because such determination will depend in part on a Non-U.S. holder's particular circumstances, the applicable withholding agent may not be able to determine whether (or to what extent) a Non-U.S. holder is treated as receiving a dividend for U.S. federal income tax purposes. Therefore, the applicable withholding agent may withhold tax at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty) on the gross amount of any consideration paid to a Non-U.S. holder in redemption of such Non-U.S. holder's KVSB Class A common stock, unless (i) the applicable withholding agent has established special procedures allowing Non-U.S. holders to certify that they are exempt from such withholding tax and (ii) such Non-U.S. holders are able to certify that they meet the requirements of such exemption (e.g., because such Non-U.S. holders are not treated as receiving a dividend under the Section 302 tests described above). However, there can be no assurance that any applicable withholding agent will establish such special certification procedures. If an applicable withholding agent withholds excess amounts from the amount payable to a Non-U.S. holder, such Non-U.S. holder generally may obtain a refund of any such excess amounts by timely filing an appropriate claim for refund with the IRS. Non-U.S. holders should consult their own tax advisors regarding the application of the foregoing rules in light of their particular facts and circumstances and any applicable procedures or certification requirements.

Information Reporting and Backup Withholding

Information returns will be filed with the IRS in connection with the proceeds from a redemption of KVSB Class A common stock. A Non-U.S. holder may have to comply with certification procedures to establish that it is not a United States person in order to avoid information reporting and backup withholding requirements. The certification procedures required to claim a reduced rate of withholding under a treaty generally will satisfy the certification requirements necessary to avoid the backup withholding as well.

Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a Non-U.S. holder will be allowed as a credit against such holder's U.S. federal income tax liability and may entitle such holder to a refund, provided that the required information is timely furnished to the IRS.

Foreign Account Tax Compliance Act Withholding Taxes

Sections 1471 through 1474 of the Code and the Treasury regulations and administrative guidance promulgated thereunder (commonly referred to as the 'Foreign Account Tax Compliance Act' or 'FATCA'), impose withholding of 30% on payments of dividends on the KVSB Class A common stock to 'foreign financial institutions' (which is broadly defined for this purpose and in general includes investment vehicles) and certain other non-U.S. entities unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied by, or an exemption applies to, the payee (typically certified by the delivery of a properly completed IRS Form W-8BEN-E). The IRS has issued proposed regulations (on which taxpayers may rely until final regulations are issued) that would generally not apply these withholding requirements to gross proceeds from sales or other disposition proceeds from the KVSB Class A common stock. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules. Under certain circumstances, a Non-U.S. holder might be eligible for refunds or credits of such withholding taxes, and a Non-U.S. holder might be required to file a U.S. federal income tax return to claim such refunds or credits. Prospective investors should consult their tax advisors regarding the effects of FATCA on the redemption of their KVSB Class A common stock.

THE INFORMATION PROVIDED ABOVE IS NOT TAX ADVICE. YOU ARE URGED TO CONSULT YOUR TAX ADVISOR WITH RESPECT TO THE APPLICATION OF U.S. FEDERAL INCOME TAX LAWS TO YOUR PARTICULAR SITUATION, AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR THE LAWS OF ANY STATE, LOCAL OR FOREIGN JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Material U.S. Federal Income Tax Consequences of the Merger

The following is a discussion of certain material U.S. federal income tax consequences of the Merger to U.S. holders (as defined below) of Nextdoor common stock whose shares are converted into the right to receive the Aggregate Merger Consideration. This discussion is based on the Code, and administrative pronouncements, judicial decisions and final, temporary and proposed Treasury Regulations as of the date hereof, which are subject to change, possibly on a retroactive basis, and changes to any of which subsequent to the date of this proxy statement/prospectus may affect the tax consequences described herein.

This discussion addresses only U.S. Holders who hold shares of Nextdoor common stock as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment) and exchange such shares pursuant to the Merger (and does not address holders who exercise dissenter's or appraisal rights under Delaware Law). This discussion is based upon the assumption that the Merger will be completed in accordance with the Business Combination Agreement and as described in this proxy statement/prospectus. Holders of Nextdoor common stock that are not U.S. Holders should consult their tax advisors as to the tax consequences of the Merger. Moreover, this discussion does not address any U.S. federal tax consequences other than income tax consequences (such as estate, gift or other non-income tax consequences) or any state, local or foreign income or non-income tax consequences. In addition, this discussion is a summary only and does not describe all of the tax consequences that may be relevant to holders of Nextdoor common stock in light of their particular circumstances, including but not limited to the alternative minimum tax, the Medicare tax on certain net investment income and the different consequences that may apply if such holders of Nextdoor common stock are subject to special rules that apply to certain types of investors, including but not limited to:

•financial institutions or financial services entities;

•broker-dealers;

•governments or agencies or instrumentalities thereof;

•regulated investment companies;

•real estate investment trusts;

•expatriates or former long-term residents of the United States;

•individual retirement or other tax-deferred accounts;

•persons owning (actually or constructively) 5% or more of Nextdoor common stock (by vote or value);

•persons whose stock in Nextdoor constitutes 'qualified small business stock' within the meaning of Sections 1202 and/or 1045 of the U.S. Internal Revenue Code of 1986, as amended (the 'Code');

•insurance companies;

•dealers or traders subject to a mark-to-market method of accounting with respect to their Nextdoor common stock;

•persons holding Nextdoor common stock as part of a 'straddle,' constructive sale, hedge, conversion or other integrated transaction or similar transaction;

•persons owning (actually or constructively) any Nextdoor securities;

•U.S. holders (as defined below) whose functional currency is not the U.S. dollar;

•partnerships or other pass-through entities or arrangements for U.S. federal income tax purposes and any beneficial owners of such entities;

•controlled foreign corporations;

155

•passive foreign investment companies;

•a person required to accelerate the recognition of any item of gross income as a result of such income being recognized on an applicable financial statement; and

•tax-exempt entities.

If a holder of Nextdoor common stock is a partner in a partnership (or member in a pass-through entity or other arrangement treated as a partnership) for U.S. federal income tax purposes, the U.S. federal income tax treatment of the Merger to such holder will generally depend on that holder's status and the activities of the partnership (or other pass-through entity). Partners in partnerships (and members in other pass-through entities) should consult their own tax advisors about the consequences of the Merger to them.

For purposes of this discussion, the term 'U.S. holder' means a beneficial owner of Nextdoor common stock who or that is, for U.S. federal income tax purposes:

•an individual who is a citizen or resident of the United States;

•a corporation (or other entity taxable as a corporation) organized in or under the laws of the United States, any state thereof or the District of Columbia;

•an estate the income of which is included in gross income for U.S. federal income tax purposes regardless of its source; or

Characterization of the Merger

The parties to the Merger Agreement intend that the Merger will qualify as a tax-free 'reorganization' within the meaning of Section 368(a) of the Code. The parties agree to report the Merger as a tax-free reorganization for all tax purposes, unless otherwise required by a Governmental Authority as a result of a 'determination' within the meaning of Section 1313(a) of the Code. Based on factual representations contained in letters provided by Nextdoor and KVSB, and on certain customary factual assumptions, all of which representations and assumptions must continue to be true and accurate as of the effective time of the Merger, in the opinion of Fenwick & West LLP, counsel to Nextdoor, the Merger will qualify as a 'reorganization' within the meaning of Section 368(a) of the Code. However, this opinion is not binding on the IRS. No ruling has been or will be sought from the IRS as to the U.S. federal income tax consequences of the Business Combination. It is not a condition to the completion of the Merger that any party to the Merger Agreement receive an opinion of counsel to the effect that the Merger will so qualify. The IRS may disagree with the discussion herein, and its determination may be upheld by a court. Moreover, there can be no assurance that future legislation, regulations, administrative rulings or court decisions will not adversely affect the accuracy of the statements in this discussion. Holders of Nextdoor common stock should consult with their tax advisors regarding the tax consequences of the Merger and the requirements that must be satisfied in order for the Merger to qualify as a 'reorganization' under Section 368(a) of the Code, with respect to the application of U.S. federal tax laws to their particular situation, as well as any tax consequences arising under the laws of any state, local or foreign jurisdiction.

U.S. Federal Income Tax Consequences for U.S. Holders

Assuming that the Merger qualifies as a 'reorganization' under the provisions of section 368(a) of the Code, the following tax consequences generally will result to U.S. Holders who exchange stock of Nextdoor for New Nextdoor Class B common stock:

156

U.S. Holder in the Merger generally will be the same as the aggregate tax basis of common stock of Nextdoor surrendered in exchange therefor. The holding period of New Nextdoor Class B common stock received by a U.S. Holder in the Merger will include the holding period of the common stock of Nextdoor surrendered therefor by the U.S. Holder in the Merger.

Tax Reporting for Significant Holders

Assuming that the Merger qualifies as a reorganization described above, each holder of Nextdoor stock who is required to file a U.S. federal income tax return and who is a 'significant holder' will be required to file a statement with such holder's U.S. federal income tax return in accordance with Treasury Regulations Section 1.368-3(b) setting forth such holder's basis in the common stock of Nextdoor surrendered and the fair market value of the New Nextdoor Class B common stock received in the Merger. A 'significant holder' is a holder of common stock of Nextdoor who, immediately before the Merger, owned at least 1% (by vote or value) of the outstanding stock of Nextdoor or securities of Nextdoor with a tax basis of at least $1 million.

Consequences if the Merger Does Not Qualify as a Reorganization under Section 368(a) of the Code

If the Merger were not to qualify as a reorganization, the Merger will be a taxable sale of the holders' common stock of Nextdoor. U.S. Holders will recognize gain or loss equal to the difference between the fair market value of the New Nextdoor Class B common stock received and their basis in the common stock of Nextdoor exchanged therefor. Such capital gain or loss will be long-term if the U.S. Holder has held the common stock of Nextdoor for more than one year as of the Closing Date, and will be short-term if the common stock of Nextdoor has been held for one year or less. The amount and character of any such gain will be determined separately with respect to each block of stock owned by such U.S. Holder. For purposes of the foregoing, a block of stock is shares of a particular class acquired on the same day and at the same price. The tax basis of the New Nextdoor Class B common stock received by a U.S. Holder in the Merger generally will be the aggregate value of the common stock of Nextdoor exchanged therefor. The holding period of New Nextdoor Class B common stock received by a U.S. Holder in the Merger will begin when such shares are received.

Whether or not the Merger qualifies as a reorganization, Nextdoor will not recognize corporate-level gain or loss as a result of the Merger.

HOLDERS OF COMMON STOCK OF NEXTDOOR ARE URGED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE TAX CONSEQUENCES OF THE MERGER AND RELATED TRANSACTIONS BASED ON THEIR OWN CIRCUMSTANCES, INCLUDING THE UNITED STATES FEDERAL, STATE, LOCAL AND NON-U.S. TAX CONSEQUENCES OF THE MERGER APPLICABLE TO THEM.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

Defined terms included below have the same meaning as terms defined and included elsewhere in this proxy statement/prospectus. Unless the context otherwise requires, all references in this section to 'New Nextdoor' refer to KVSB and its wholly owned subsidiaries after giving effect to the Transactions.

The unaudited pro forma condensed combined financial information of New Nextdoor has been prepared in accordance with Article 11 of Regulation S-X as amended by the final rule, Release No. 33-10786 'Amendments to Financial Disclosures about Acquired and Disposed Businesses' ('Article 11 of Regulation S-X') and presents the combination of the historical financial information of KVSB and Nextdoor adjusted to give effect to the Transactions and the other related events contemplated by the Merger Agreement.

The unaudited pro forma condensed combined balance sheet as of June 30, 2021 combines the historical audited balance sheet of KVSB as of June 30, 2021 with the historical unaudited consolidated balance sheet of Nextdoor as of June 30, 2021 on a pro forma basis as if the Transactions and the other related events, summarized below, had been consummated on June 30, 2021.

The unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X. The adjustments in the unaudited pro forma condensed combined financial information have been identified and presented to provide relevant information in accordance with GAAP necessary for an illustrative understanding of New Nextdoor upon consummation of the Transactions. Assumptions and estimates underlying the unaudited pro forma adjustments set forth in the unaudited pro forma condensed combined financial information are described in the accompanying notes.

The unaudited pro forma condensed combined financial information has been presented for illustrative purposes only and is not necessarily indicative of the operating results and financial position that would have been achieved had the Transactions occurred on the dates indicated, and does not reflect adjustments for any anticipated synergies,

operating efficiencies, tax savings, or cost savings. Any cash proceeds remaining after the consummation of the Transactions and the other related events contemplated by the Merger Agreement are expected to be used for general corporate purposes. The unaudited pro forma condensed combined financial information does not purport to project the future operating results or financial position of New Nextdoor following the completion of the Transactions. The unaudited pro forma adjustments represent management's estimates based on information available as of the date of these unaudited pro forma condensed combined financial information and are subject to change as additional information becomes available and analyses are performed. KVSB and Nextdoor have not had any historical relationship prior to the Transactions. Accordingly, no pro forma adjustments were required to eliminate activities between the companies.

The unaudited pro forma condensed combined financial information contained herein assumes that the KVSB stockholders approve the Transactions. Pursuant to the current certificate of incorporation, KVSB's public stockholders may elect to redeem their public shares for cash even if they approve the Transactions. KVSB cannot predict how many of its public stockholders will exercise their right to redeem their public shares of KVSB Class A common stock for cash. The unaudited pro forma condensed combined financial information has been prepared assuming two redemption scenarios after giving effect to the Transactions and the other related events, as follows:

The following summarizes the pro forma New Nextdoor common stock issued and outstanding immediately after the Transactions, based on Nextdoor's capitalization as of August 31, 2021, presented under the two assumed redemption scenarios:

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

1.Basis of Presentation

The Transactions are expected to be accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, KVSB is expected to be treated as the 'acquired' company for financial reporting purposes. Accordingly, the Transactions are expected to be reflected as the equivalent of Nextdoor issuing stock for the net assets of KVSB, accompanied by a recapitalization. The net assets of KVSB will be stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Transactions will be those of Nextdoor.

The unaudited pro forma condensed combined statement of operations for the six months ended June 30, 2021 combines the historical audited statement of operations of KVSB from January 29, 2021 (date of inception) to June 30, 2021 and the historical unaudited consolidated statement of operations of Nextdoor for the six months ended June 30, 2021 on a pro forma basis as if the Transactions and the other related events, summarized above, had been consummated on January 1, 2020, the beginning of the earliest period presented. The date of inception for KVSB was January 29, 2021, therefore the unaudited pro forma condensed combined statement of operations for the year ended December 31, 2020 presents only the historical audited consolidated statement of operations of Nextdoor for the year ended December 31, 2020 on a pro forma basis as if the Transactions and the other related events, summarized below, had been consummated on January 1, 2020, the beginning of the earliest period presented.

•the historical audited financial statements of KVSB as of June 30, 2021 and for the period from January 29, 2021 (date of inception) to June 30, 2021;

Management has made significant estimates and assumptions in its determination of the pro forma adjustments based on information available as of the date of this proxy statement/prospectus. As the unaudited pro forma condensed combined financial information has been prepared based on these preliminary estimates, the final amounts recorded may differ materially from the information presented as additional information becomes available. Management considers this basis of presentation to be reasonable under the circumstances.

One-time direct incremental transaction costs anticipated to be incurred prior to, or concurrent with, the Closing are reflected on the unaudited pro forma condensed combined balance sheet as a direct reduction to New Nextdoor's additional paid-in capital and are assumed to be cash settled.

167

2.Adjustments to Unaudited Pro Forma Condensed Combined Financial Information

The maximum redemption scenario takes into consideration the effects of adjustments to the unaudited pro forma condensed combined financial information presented under the no redemptions scenario plus additional adjustments necessary to present the unaudited pro forma condensed combined financial information under the maximum redemptions scenario.

Adjustments to Unaudited Pro Forma Condensed Combined Balance Sheet

The adjustments included on the unaudited pro forma condensed combined balance sheet as of June 30, 2021 are as follows:

(A) Reflects the reclassification of $416.4 million of funds held in the trust account to cash and cash equivalents that becomes available for general corporate use by New Nextdoor.

(B) Reflects the gross proceeds of $270.0 million from the sale and issuance of 27,000,000 shares of New Nextdoor Class A common stock to PIPE Investors, which includes 750,000 shares of New Nextdoor Class A common stock to the Sponsor Related PIPE Investors and 4,500,000 shares of New Nextdoor Class A common stock to the Nextdoor PIPE Investors, including 500,000 shares of New Nextdoor Class A common stock to Nextdoor's Chief Executive Officer and President, at a purchase price of $10.00 per share pursuant to the PIPE Investment. Refer to Tickmark (C) for the treatment of the associated direct and incremental transaction costs.

(C) Represents the preliminary estimated direct and incremental transaction costs of $48.1 million expected to be incurred by KVSB and Nextdoor in connection with the Transactions and the PIPE Investment, of which $0.6 million has been paid by KVSB as of June 30, 2021 and includes the deferred underwriting fees of $14.6 million, and includes Nextdoor deferred transaction costs incurred as of June 30, 2021 of $2.1 million, of which $1.6 million was unpaid and recorded in accrued expenses and other current liabilities.

(D) Reflects the conversion of Nextdoor preferred stock into Nextdoor common stock on a one-to-one basis pursuant to the conversion rate immediately prior to the Effective Time.

(E) Represents the issuance of 302,532,879 shares of New Nextdoor Class B common stock to holders of Nextdoor common stock at the Closing pursuant to the Merger Agreement to effect the reverse recapitalization.

(F) Reflects the reclassification of KVSB's Class A common stock subject to possible redemption to permanent equity assuming no redemptions and immediate conversion of 41,634,412 shares of KVSB's Class A common stock into shares of New Nextdoor Class A common stock on a one-to-one basis in connection with the Transactions.

(G) Reflects the conversion of 1,132,688 shares of KVSB Class A common stock private placement Sponsor shares into shares of New Nextdoor Class B common stock on a one-to-one basis in connection with the Transactions.

(H) Reflects the conversion of all 5,000,000 shares of KVSB's Class B common stock into 7,347,249 shares of New Nextdoor Class B common stock in connection with the Closing per the Sponsor Support Agreement.

(I) Reflects the elimination of KVSB's historical accumulated deficit with a corresponding adjustment to additional paid-in capital for New Nextdoor in connection with the reverse recapitalization at the Closing.

(J) Reflects stock-based compensation expense of $8.5 million as of June 30, 2021 related to a stock option to purchase 743,184 shares of Nextdoor common stock granted to Nextdoor's Chief Executive Officer and President, for which the performance-based vesting condition will be satisfied upon the Closing of the Transactions, which is reflected as an increase to additional paid-in capital and accumulated deficit, as further described in Note 10 to the Nextdoor consolidated financial statements included elsewhere in this proxy statement/prospectus. The option will vest in a single installment upon the Closing subject to her continuous employment through such date.

(K) Reflects the gross proceeds of $10.0 million from the sale and issuance of 1,000,000 shares of New Nextdoor Class A common stock to the Sponsor at a purchase price of $10.00 per share pursuant to the Forward

168

Purchase Agreement. The Sponsor will only be required to purchase additional shares under the Forward Purchase Agreement if the Minimum Cash Condition would not otherwise be satisfied and therefore is only reflected in the Maximum Redemptions scenario.

(L) Represents the cash disbursed under the maximum redemptions scenario to redeem 24,932,638 public shares of KVSB Class A common stock in connection with the Transactions at an assumed redemption price of approximately $10.00 per share based on funds held in the trust account as of June 30, 2021 and still satisfy the Minimum Cash Condition required to consummate the Transactions of at least $400.0 million after giving effect to the proceeds from the PIPE Investment, the payment of the estimated transaction costs, and the proceeds from the Sponsor Forward Purchase Agreement.

(M) Reflects the exchange of all 5,000,000 shares of KVSB's Class K common stock, classified as a derivative liability, into 3,061,354 shares of New Nextdoor Class B common stock in connection with the Closing per the Sponsor Support Agreement.

Adjustments to Unaudited Pro Forma Condensed Combined Statements of Operations

The adjustments included in the unaudited pro forma condensed combined statements of operations for the six months ended June 30, 2021 and the year ended December 31, 2020 were as follows:

(AA) Represents the elimination of the gain on marketable securities, dividends, and interest, related to funds held in the KVSB trust account.

(BB) Reflects the elimination of the impact of the change in fair value of the derivative liability as these securities are exchanged into shares of New Nextdoor Class B common stock in connection with the Closing per the Sponsor Support Agreement. The financing expenses related to the derivative classified instrument for KVSB's Class K founder shares incurred at KVSB's inception of $36.5 million have not been eliminated from the unaudited pro forma condensed combined statement of operations as the expenses incurred at inception are not affected by the exchange of the shares of KVSB's Class K common stock into shares of New Nextdoor Class B common stock in connection with the Closing per the Sponsor Support Agreement.

(CC) Reflects stock-based compensation expense of $8.5 million related to a stock option to purchase 743,184 shares of Nextdoor common stock granted to Nextdoor's Chief Executive Officer and President, for which the performance-based vesting condition will be satisfied upon the Closing of the Transactions, as further described in Note 10 to the Nextdoor consolidated financial statements included elsewhere in this proxy statement/prospectus. The option will vest in a single installment upon the Closing subject to her continuous employment through such date.

3.Net Loss Per Share

Represents the net loss per share calculated under the two-class method using the pro forma basic and diluted weighted average shares outstanding of New Nextdoor common stock as a result of the pro forma adjustments. The Company used the two-class method to compute net loss per share, because it had issued multiple classes of common stock. The two-class method requires earnings for the period to be allocated between multiple classes of common stock based upon their respective rights to receive distributed and undistributed earnings. As the Transactions are being reflected as if the reverse recapitalization had occurred on January 1, 2020, the calculation of weighted average shares outstanding for pro forma basic and diluted net loss per share assumes the shares issued in connection with the Transactions have been outstanding for the entire periods presented. If the maximum number of shares are redeemed, this calculation is retroactively adjusted to eliminate such shares for the entire period.

INFORMATION ABOUT KVSB

Unless the context otherwise requires, all references in this section to the 'Company,' 'we,' 'us' or 'our' refer to KVSB prior to the consummation of the Business Combination.

General

KVSB is a blank check company incorporated on January 29, 2021 as a Delaware corporation for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. Although KVSB is not limited to a particular industry or sector for purposes of consummating a business combination, KVSB focuses on businesses in the technology industries primarily located in the United States. KVSB has neither engaged in any operations nor generated any revenue to date. Based on KVSB's business activities, it is a 'shell company' as defined under the Exchange Act because it has no operations and nominal assets consisting almost entirely of cash.

On March 26, 2021, KVSB consummated its initial public offering of its public shares, excluding additional public shares sold pursuant to the partial exercise of the underwriters' option to purchase additional public shares to cover over-allotments. On March 26, 2021, KVSB's underwriters exercised in part their option to purchase additional public shares. The underwriters exercised their option to purchase an additional 1,634,412 public shares from KVSB at a price of $10.00 per share less the underwriting discount. In total, KVSB sold 41,634,412 public shares in connection with its initial public offering.

Substantially concurrently with the closing of the initial public offering, KVSB completed the private sale of 1,100,000 shares of Class A common stock of KVSB at a purchase price of $10.00 per private placement share, to KVSB's Sponsor, Khosla Ventures SPAC Sponsor II LLC, generating aggregate gross proceeds to KVSB of $11,000,000. An additional 32,688 private placement shares were sold in connection with the underwriters' partial exercise of their over-allotment option for total proceeds of $326,880. As of June 30, 2021, the Sponsor has purchased 1,132,688 private placement shares for an aggregate purchase price of $11,326,880. The private placement shares are identical to the shares sold in KVSB's initial public offering except that, so long as they are held by the Sponsor or its permitted transferees, they may not, subject to certain limited exceptions, be transferred, assigned or sold by the Sponsor until 30 days after the completion of KVSB's initial business combination.

Following the closing of KVSB's initial public offering, a total of $416,334,120, comprised of proceeds from the initial public offering, the partial exercise of the over-allotment option and the sale of the private placement shares, were placed in the trust account. The proceeds held in the trust account may be invested by the trustee only in U.S. government treasury bills with a maturity of 185 days or less or in money market funds investing solely in U.S. Treasury securities and meeting certain conditions under Rule 2a-7 under the Investment Company Act of 1940, as amended. As of June 30, 2021, funds in the trust account totaled $416,350,445. These funds will remain in the trust account, except for the withdrawal of interest to fund KVSB's working capital requirements, subject to an annual limit of $500,000, and/or to pay taxes, if any, until the earliest of (1) the completion of a business combination (including the Closing), (2) the redemption of any public shares properly tendered in connection with a stockholder vote to amend the Existing Organizational Documents to modify the substance or timing of KVSB's obligation to redeem 100% of the public shares if it does not complete a business combination by the Liquidation Date and (3) the redemption of all of the public shares if KVSB is unable to complete a business combination by the Liquidation Date, subject to applicable law.

Effecting KVSB's Initial Business Combination

Fair Market Value of Target Business

The rules of the Nasdaq and the Existing Charter require that KVSB's initial business combination must be with one or more operating businesses or assets with a fair market value equal to at least 80% of the net assets held in the trust account (net of amounts disbursed to management for the payment of taxes and excluding the amount of any deferred underwriting discount held in trust). The KVSB Board determined that this test was met in connection with the proposed Business Combination.

171

Stockholder Approval of Business Combination

KVSB is seeking stockholder approval of the Business Combination at the special meeting, at which stockholders may elect to redeem their shares, regardless of if or how they vote in respect of the BCA Proposal, into their pro rata portion of the trust account, calculated as of two business days prior to the consummation of the Business Combination including interest earned on the funds held in the trust account and not previously released to us (net of taxes payable). KVSB will consummate the Business Combination only if we have net tangible assets of at least $5,000,001 upon such consummation and the Condition Precedent Proposals have been approved. Notwithstanding the foregoing, a public stockholder, together with any affiliate of such public stockholder or any other person with whom such public stockholder is acting in concert or as a 'group' (as defined in Section 13(d)(3) of the Exchange Act), will be restricted from redeeming its public shares with respect to more than an aggregate of 15% of the public shares. Accordingly, if a public stockholder, alone or acting in concert or as a group, seeks to redeem more than 15% of the public shares, then any such shares in excess of that 15% limit would not be redeemed for cash.

At any time at or prior to the Business Combination, subject to applicable securities laws (including with respect to material nonpublic information), the Sponsor, the existing stockholders of Nextdoor or our or their respective directors, officers, advisors or respective affiliates may (i) purchase public shares from institutional and other investors who vote, or indicate an intention to vote, against any of the Condition Precedent Proposals, or elect to redeem, or indicate an intention to redeem, public shares, (ii) execute agreements to purchase such shares from such investors in the future, or (ii) enter into transactions with such investors and others to provide them with incentives to acquire public shares, vote their public shares in favor of the Condition Precedent Proposals or not redeem their public shares. Such a purchase may include a contractual acknowledgement that such stockholder, although still the record holder of KVSB's shares, is no longer the beneficial owner thereof and therefore agrees not to exercise its redemption rights. In the event that the Sponsor, the existing stockholders of Nextdoor or our or their respective directors, officers, advisors, or respective affiliates purchase shares in privately negotiated transactions from public stockholders who have already elected to exercise their redemption rights, such selling stockholders would be required to revoke their prior elections to redeem their shares. The purpose of such share purchases and other transactions would be to increase the likelihood of (1) satisfaction of the requirement that the BCA Proposal, the Charter Proposal, the Equity Incentive Plan Proposal, the ESPP Proposal and the Adjournment Proposal by a requisite vote of our stockholders, (2) satisfaction of the Minimum Cash Condition, (3) otherwise limiting the number of public shares electing to redeem and (4) KVSB's net tangible assets (as determined in accordance with Rule 3a51(g)(1) of the Exchange Act) being at least $5,000,001.

Liquidation if No Business Combination

If KVSB has not completed the Business Combination with New Nextdoor by the Liquidation Date and has not completed another business combination by such date, KVSB will: (1) cease all operations except for the purpose of winding up; (2) as promptly as reasonably possible but not more than 10 business days thereafter, redeem the 41,634,412 public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest (less up to $100,000 of interest to pay dissolution expenses and which interest will be net of taxes payable), divided by the number of then issued and outstanding public shares, which redemption will completely extinguish public stockholders' rights as stockholders (including the right to receive further liquidating distributions, if any); and (3) as promptly as reasonably possible following such redemption, subject to the approval of KVSB's remaining stockholders and its board of directors, liquidate and dissolve, subject in each case to its obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

172

Sponsor has entered into a letter agreement with KVSB, dated as of March 23, 2021 pursuant to which they have agreed to waive their redemption rights with respect to their founder shares and any public shares held by them in connection with (i) the completion of our initial business combination and (ii) a stockholder vote to approve an amendment to our amended and restated certificate of incorporation that would affect the substance or timing of our obligation to allow redemption in connection with our initial business combination or to redeem 100% of our public shares if we have not completed an initial business combination within the period to consummate the initial business combination. However, if Sponsor owns any public shares, they will be entitled to liquidating distributions from the trust account with respect to such public shares if KVSB fails to complete its business combination within the allotted time period.

KVSB expects that all costs and expenses associated with implementing its plan of dissolution, as well as payments to any creditors, will be funded from amounts held outside the trust account, although it cannot assure you that there will be sufficient funds for such purpose. However, if those funds are not sufficient to cover the costs and expenses associated with implementing KVSB's plan of dissolution, to the extent that there is any interest accrued in the trust account not required to pay taxes, KVSB may request the trustee to release to us an additional amount of up to $100,000 of such accrued interest to pay those costs and expenses.

The proceeds deposited in the trust account could, however, become subject to the claims of KVSB's creditors which would have higher priority than the claims of KVSB's public stockholders. KVSB cannot assure you that the actual per-share redemption amount received by public stockholders will not be substantially less than $10.00. See 'Risk Factors - Risks Related to the Business Combination and KVSB - If third parties bring claims against us, the proceeds held in the trust account could be reduced and the per share redemption amount received by stockholders may be less than $10.00 per share (which was the offering price per unit in our initial public offering)' and other risk factors contained herein. While KVSB intend to pay such amounts, if any, KVSB cannot assure you that KVSB will have funds sufficient to pay or provide for all creditors' claims.

Although KVSB will seek to have all vendors, service providers (other than KVSB's independent auditors), prospective target businesses and other entities with which KVSB does business execute agreements with us waiving any right, title, interest or claim of any kind in or to any monies held in the trust account for the benefit of KVSB's public stockholders, there is no guarantee that they will execute such agreements or even if they execute such agreements that they would be prevented from bringing claims against the trust account including but not limited to fraudulent inducement, breach of fiduciary responsibility or other similar claims, as well as claims challenging the enforceability of the waiver, in each case in order to gain an advantage with respect to a claim against KVSB's assets, including the funds held in the trust account. If any third party refuses to execute an agreement waiving such claims to the monies held in the trust account, KVSB's management will perform an analysis of the alternatives available to it and will enter into an agreement with a third party that has not executed a waiver only if management believes that such third party's engagement would be significantly more beneficial to us than any alternative. Examples of possible instances where KVSB may engage a third party that refuses to execute a waiver include the engagement of a third party consultant whose particular expertise or skills are believed by management to be significantly superior to those of other consultants that would agree to execute a waiver or in cases where KVSB is unable to find a service provider willing to execute a waiver. In addition, there is no guarantee that such entities will agree to waive any claims they may have in the future as a result of, or arising out of, any negotiations, contracts or agreements with us and will not seek recourse against the trust account for any reason. Upon redemption of KVSB's public shares, if KVSB has not completed KVSB's initial business combination within the required time period, or upon the exercise of a redemption right in connection with KVSB's initial business combination, KVSB will be required to provide for payment of claims of creditors that were not waived that may be brought against us within the 10 years following redemption. In order to protect the amounts held in the trust account, Sponsor has agreed that it will be liable to us if and to the extent any claims by a third party (other than KVSB's independent auditors) for services rendered or products sold to us, or a prospective target business with which KVSB has discussed entering into a transaction agreement, reduce the amount of funds in the trust account to below (i) $10.00 per public share or (ii) such lesser amount per public share held in the trust account as of the date of the liquidation of the trust account, due to reductions in value of the trust assets, in each case net of the amount of interest which may be withdrawn to fund KVSB's working capital requirements, subject to an annual limit of $500,000, and/or to pay taxes, except as to any claims by a third party who executed a waiver of any and all rights to

173

seek access to the trust account and except as to any claims under KVSB's indemnity of the underwriters of KVSB's initial public offering against certain liabilities, including liabilities under the Securities Act. In the event that an executed waiver is deemed to be unenforceable against a third party, then the Sponsor will not be responsible to the extent of any liability for such third-party claims. KVSB has not independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and KVSB believes that the Sponsor's only assets are securities of KVSB and, therefore, the Sponsor may not be able to satisfy those obligations. None of KVSB's other directors or officers will indemnify us for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

In the event that the proceeds in the trust account are reduced below (i) $10.00 per public share or (ii) such lesser amount per public share held in the trust account as of the date of the liquidation of the trust account, due to reductions in value of the trust assets, in each case net of the amount of interest which may be withdrawn to fund KVSB's working capital requirements, subject to an annual limit of $500,000, and/or to pay taxes, and the Sponsor asserts that it is unable to satisfy its indemnification obligations or that it has no indemnification obligations related to a particular claim, KVSB's independent directors would determine whether to take legal action against the Sponsor to enforce its indemnification obligations. While KVSB currently expects that KVSB's independent directors would take legal action on KVSB's behalf against the Sponsor to enforce its indemnification obligations to us, it is possible that KVSB's independent directors in exercising their business judgment may choose not to do so in any particular instance. Accordingly, KVSB cannot assure you that due to claims of creditors the actual value of the per- share redemption price will not be substantially less than $10.00 per share. See 'Risk Factors - Risks Related to the Business Combination and KVSB - If third parties bring claims against us, the proceeds held in the trust account could be reduced and the per share redemption amount received by stockholders may be less than $10.00 per share (which was the offering price per unit in our initial public offering).

KVSB will seek to reduce the possibility that the Sponsor will have to indemnify the trust account due to claims of creditors by endeavoring to have all vendors, service providers (other than KVSB's independent auditors), prospective target businesses and other entities with which KVSB does business execute agreements with us waiving any right, title, interest or claim of any kind in or to monies held in the trust account. The Sponsor will also not be liable as to any claims under KVSB's indemnity of the underwriters of the initial public offering against certain liabilities, including liabilities under the Securities Act.

If KVSB files a winding-up or bankruptcy petition or an involuntary winding-up or bankruptcy petition is filed against us that is not dismissed, the proceeds held in the trust account could be subject to applicable insolvency law, and may be included in KVSB's insolvency estate and subject to the claims of third parties with priority over the claims of KVSB's stockholders. To the extent any insolvency claims deplete the trust account, KVSB cannot assure you KVSB will be able to return $10.00 per share to KVSB's public stockholders. Additionally, if KVSB files a winding-up or bankruptcy petition or an involuntary winding-up or bankruptcy petition is filed against us that is not dismissed, any distributions received by stockholders could be viewed under applicable debtor/creditor and/or insolvency laws as a voidable performance. As a result, a bankruptcy court could seek to recover some or all amounts received by KVSB's stockholders. Furthermore, the KVSB Board may be viewed as having breached its fiduciary duty to KVSB's creditors or may have acted in bad faith, and thereby exposing itself and us to claims of punitive damages, by paying public stockholders from the trust account prior to addressing the claims of creditors. KVSB cannot assure you that claims will not be brought against us for these reasons. See 'Risk Factors - Risks Related to the Business Combination and KVSB - If, after we distribute the proceeds in the trust account to our public stockholders, KVSB files a bankruptcy petition or an involuntary bankruptcy petition is filed against us that is not dismissed, a bankruptcy court may seek to recover such proceeds, and we and our board of directors may be exposed to claims of punitive damages.'

KVSB's public stockholders will be entitled to receive funds from the trust account only upon the earliest to occur of: (1) KVSB's completion of an initial business combination, and then only in connection with those shares of KVSB Class A common stock that such stockholder properly elected to redeem, subject to the limitations

174

described herein; (2) the redemption of any public shares properly submitted in connection with a stockholder vote to amend the Existing Organizational Documents (A) to modify the substance or timing of KVSB's obligation to allow redemption in connection with KVSB's initial business combination or to redeem 100% of the public shares if KVSB does not complete KVSB's initial business combination by the Liquidation Date or (B) with respect to any other provision relating to stockholders' rights or pre-initial business combination activity; and (3) the redemption of the public shares if KVSB has not completed an initial business combination by the Liquidation Date, subject to applicable law. In no other circumstances will a stockholder have any right or interest of any kind to or in the trust account.

Facilities

KVSB currently maintains its executive offices at 2128 Sand Hill Road, Menlo Park, California 94025, and our telephone number is (650) 376-8500. KVSB considers its current office space adequate for KVSB's current operations.

Upon consummation of the Business Combination, the principal executive offices of New Nextdoor will be located at 420 Taylor Street, San Francisco, California 94012.

Legal Proceedings

On September 3, 2021, putative stockholder Evan Umbright filed a lawsuit naming KVSB and certain of its directors in the Delaware Court of Chancery, under the caption Umbright v. Khosla Ventures Acquisition Co. II, CA No.2021-0762-LWW. The complaint alleges that the holders of Class A common stock have been denied a right to vote as a separate class on a proposed amendment to KVSB's charter to increase the authorized shares of Class A common stock, in violation of Section 242(b)(2) of the DGCL. The complaint seeks preliminary and final injunctive relief and damages, along with other relief. On September 8, 2021, the plaintiff filed a motion for preliminary injunction. A hearing date has not been set. KVSB believes these claims are without merit.

Employees

KVSB currently has three executive officers. Members of KVSB's management team are not obligated to devote any specific number of hours to KVSB's matters but they intend to devote as much of their time as they deem necessary to KVSB's affairs until KVSB has completed KVSB's initial business combination. The amount of time that any members of KVSB's management team will devote in any time period will vary based on whether a target business has been selected for KVSB's business combination and the current stage of the Business Combination process.

Competition

If KVSB succeeds in effecting the Business Combination, there will be, in all likelihood, significant competition from Nextdoor's competitors. KVSB cannot assure you that, subsequent to the Business Combination, New Nextdoor will have the resources or ability to compete effectively. Information regarding New Nextdoor's competition is set forth in the sections entitled 'Information about Nextdoor - Competition.'

KVSB'S MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of KVSB's financial condition and results of operations should be read in conjunction with KVSB's consolidated financial statements and notes to those statements included in this proxy statement/prospectus. Certain information contained in the discussion and analysis set forth below includes forward-looking statements that involve risks and uncertainties. KVSB's actual results may differ materially from those anticipated in these forward-looking statements as a result of many factors. Please see 'Cautionary Statement Regarding Forward-Looking Statements' and 'Risk Factors' in this proxy statement/prospectus.

Unless the context otherwise requires, all references in this section to the 'we,' 'us,' 'our,' the 'Company' or 'KVSB' refer to KVSB prior to the consummation of the Business Combination.

Overview

We are a blank check company incorporated on January 29, 2021 as a Delaware corporation and formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. We reviewed a number of opportunities to enter into a business combination with an operating business, and entered into the Merger Agreement on July 6, 2021. We intend to effectuate our initial business combination using cash from the proceeds of the IPO and the private placement of the private placement shares, our shares, and proceeds from the PIPE investment.

The issuance of additional shares of our stock in connection with a business combination to the owners of the target or other investors:

•may significantly dilute the equity interest of investors, which dilution would increase if the anti-dilution provisions in our Class B common stock resulted in the issuance of our Class A common stock on a greater than one-to-one basis upon conversion of our Class B common stock;

•may subordinate the rights of holders of our Class A common stock if shares of preferred stock are issued with rights senior to those afforded our Class A common stock;

•could cause a change in control if a substantial number of shares of our Class A common stock are issued, which may affect, among other things, our ability to use our net operating loss carry forwards, if any, and could result in the resignation or removal of our present officers and directors;

•may have the effect of delaying or preventing a change of control of us by diluting the share ownership or voting rights of a person seeking to obtain control of us; and

•may adversely affect prevailing market prices for our Class A common stock.

Similarly, if we issue debt securities, or otherwise incur significant debt, it could result in:

•default and foreclosure on our assets if our operating revenues after an initial business combination are insufficient to repay our debt obligations;

•acceleration of our obligations to repay the indebtedness even if we make all principal and interest payments when due if we breach certain covenants that require the maintenance of certain financial ratios or reserves without a waiver or renegotiation of that covenant;

•our immediate payment of all principal and accrued interest, if any, if the debt is payable on demand;

•our inability to obtain necessary additional financing if the debt contains covenants restricting our ability to obtain such financing while the debt is outstanding;

•our inability to pay dividends on our common stock;

178

•using a substantial portion of our cash flow to pay principal and interest on our debt, which will reduce the funds available for dividends on our common stock if declared, our ability to pay expenses, make capital expenditures and acquisitions and fund other general corporate purposes;

•limitations on our flexibility in planning for and reacting to changes in our business and in the industry in which we operate;

•increased vulnerability to adverse changes in general economic, industry and competitive conditions and adverse changes in government regulation; and

•limitations on our ability to borrow additional amounts for expenses, capital expenditures, acquisitions, debt service requirements and execution of our strategy and other purposes and other disadvantages compared to our competitors who have less debt.

As indicated in the accompanying financial statements, as of June 30, 2021, we had $978,280 in cash. Further, we expect to incur significant costs in the pursuit of our initial business combination. We cannot assure you that our plans to raise capital or to complete our initial business combination will be successful.

Results of Operations

Our entire activity from inception through June 30, 2021 related to our formation, the preparation for the IPO, and since the closing of the IPO, the search for a prospective initial business combination. We have neither engaged in any operations nor generated any revenues to date. We will not generate any operating revenues until after completion of the business combination, at the earliest. We will generate non-operating income in the form of interest and investment income on cash and cash equivalents and investments. We expect to incur increased expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as for due diligence expenses.

For the period from January 29, 2021 (inception) through June 30, 2021, we had a net loss from operations of $408,967, which consisted of $25,000 in formation costs, $283,967 in general administrative expenses, and $100,000 in franchise tax expenses. We also incurred $36,537,500 in financing expenses on derivative classified instruments, and an unrealized gain on the fair value of derivative liabilities of $20,000,000, offset by interest income and unrealized gain on marketable securities held in the Trust Account of $6,327, resulting in an overall net loss of $16,940,140 for the period from January 29, 2021 (inception) through June 30, 2021.

Liquidity and Going Concern

As of June 30, 2021, KVSB had $978,280 in its cash account, $416,350,445 in securities held in the Trust Account to be used for a Business Combination or to repurchase or redeem its common stock in connection therewith and working capital of $1,461,803. As of June 30, 2021, $6,327 of the amount on deposit in the Trust Account represented interest income, which is available for working capital needs.

If KVSB is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to, suspending the pursuit of a Business Combination. KVSB cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all.

As a result of the above, in connection with KVSB's assessment of going concern considerations in accordance with Accounting Standards Update ('ASU') 2014-15, 'Disclosures of Uncertainties about an Entity's Ability to Continue as a Going Concern,' management has determined that the liquidity condition and date for mandatory liquidation and dissolution raise substantial doubt about KVSB's ability to continue as a going concern through approximately one year from the date of filing. These financial statements do not include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should KVSB be unable to continue as a going concern.

179

Prior to the consummation of the Initial Public Offering, KVSB's liquidity needs have been satisfied through receipt of a $25,000 capital contribution from the Sponsor in exchange for the issuance of the Founder Shares to the Sponsor, and a $300,000 promissory note payable to the Sponsor.

Subsequent to the consummation of the Initial Public Offering, KVSB received the net proceeds not held in the Trust Account of approximately $3,000,000. KVSB fully repaid the note to the Sponsor in April 2021. In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of KVSB's officers and directors may, but are not obligated to, loan KVSB Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans.

The Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender's discretion, up to $1,500,000 of such Working Capital Loans may be convertible into shares of the post-transaction company at $10.00 per share at the option of the lender. As of June 30, 2021, KVSB has no borrowings under the Working Capital Loans.

Off-Balance Sheet Arrangements

We have no obligations, assets or liabilities, which would be considered off-balance sheet arrangements as of June 30, 2021. We do not participate in transactions that create relationships with unconsolidated entities or financial partnerships, often referred to as variable interest entities, which would have been established for the purpose of facilitating off-balance sheet arrangements. We have not entered into any off- balance sheet financing arrangements, established any special purpose entities, guaranteed any debt or commitments of other entities, or purchased any nonfinancial assets.

Contractual Obligations

We do not have any long-term debt, capital lease obligations, operating lease obligations or long-term liabilities.

The underwriters of our IPO are entitled to a deferred fee of $0.35 per public share, or $14,572,044 in the aggregate. The deferred fee will be waived by the underwriters in the event that the Company does not complete a business combination, subject to the terms of the underwriting agreement.

On March 23, 2021, we entered into a forward purchase agreement pursuant to which the Sponsor (together with any permitted transferees under the forward purchase agreement, the 'Khosla Entities') have agreed to purchase an aggregate of up to 1,000,000 forward purchase shares for $10.00 per share, or an aggregate maximum amount of $10,000,000, in a private placement that will close simultaneously with the closing of the initial Business Combination. The Khosla Entities will purchase a number of forward-purchase shares that will result in gross proceeds to us necessary to enable us to consummate our initial Business Combination and pay related fees and expenses, after first applying amounts available to us from the Trust Account (after paying the deferred underwriting discount and giving effect to any redemptions of Public Shares) and any other financing source obtained by us for such purpose at or prior to the consummation of our initial Business Combination, plus any additional amounts mutually agreed by us and the Khosla Entities to be retained by the post-Business Combination company for working capital or other purposes. The Khosla Entities' obligation to purchase forward-purchase shares will, among other things, be conditioned on the Business Combination (including the target assets or business, and the terms of the Business Combination) being reasonably acceptable to the Khosla Entities and on a requirement that such initial Business Combination is approved by a unanimous vote of our board of directors. In determining whether a target is reasonably acceptable to the Khosla Entities, we expect that the Khosla Entities would consider many of the same criteria as we will consider but will also consider whether the investment is an appropriate investment for the Khosla Entities.

Critical Accounting Policies

The preparation of condensed financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at

180

the date of the condensed financial statements, and income and expenses during the periods reported. Actual results could materially differ from those estimates. We have identified the following critical accounting policies:

Class K Founder Common Stock

Class K common stock was accounted for as a liability in accordance with ASC Topic 815 and presented as derivative liability on the accompanying June 30, 2021, balance sheet. The derivative liability was measured at fair value at inception and on a recurring basis, which changes in fair value presented within change in fair value of derivative liability in the statements of operations. In order to capture the market conditions associated with the Class K common stock liability, KVSB applied an approach that incorporated a Monte Carlo simulation, which involved random iterations of future stock-price paths over the contractual life of the Class K common stock. Based on assumptions regarding potential changes in control of KVSB, and the probability distribution of outcomes, the payoff to the holder was determined based on the achievement of the various market thresholds within each simulated path. The present value of the payoff in each simulated trial is calculated, and the fair value of the liability is determined by taking the average of all present values.

The inputs used as of June 30, 2021 was as follows: risk free rate of 1.48%; term in years 0.5 years; expected volatility 15% and the stock price was $9.94.

Recent Accounting Pronouncements

Management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on our condensed financial statements.

Quantitative and Qualitative Disclosures about Market Risk

As of June 30, 2021, we were not subject to any market or interest rate risk. Following the consummation of our initial public offering, the net proceeds of the IPO and the sale of the private placement shares held in the trust account are invested in U.S. government treasury obligations with a maturity of 180 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act which invest only in direct U.S. government treasury obligations. Due to the short-term nature of these investments, KVSB believes there is no associated material exposure to interest rate risk. However, if the interest rates of U.S. Treasury obligations become negative, KVSB may have less interest income available to it for payment of taxes, and a decline in the value of the assets held in the trust account could reduce the principal below the amount initially deposited in the trust account.

Controls and Procedures

Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

Evaluation of Disclosure Controls and Procedures

As required by Rules 13a-15 and 15d-15 under the Exchange Act, our Chief Executive Officer and Chief Financial Officer carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of June 30, 2021.

Based on this evaluation, our principal executive officer and principal financial and accounting officer have concluded that during the period covered by this report, our disclosure controls and procedures were not effective due to material weaknesses in internal controls over financial reporting related to the inaccurate accounting. Management identified errors in its historical financial statements related to the accounting for the Class A common stock and the Class K Founder Shares. Because the Class A common stock issued in the Initial Public Offering can be redeemed or become redeemable subject to the occurrence of future events considered outside of KVSB's

181

control, KVSB should have classified all of these redeemable shares in temporary equity and remeasured these redeemable shares to their redemption value (i.e., $10.00 per share) as of the end of the first reporting period after the date of KVSB's Initial Public Offering. Management also concluded that it incorrectly accounted for the Class K Founder Shares as permanent equity versus a derivative liability. To address these material weaknesses, management has devoted, and plans to continue to devote, significant effort and resources to the remediation and improvement of its internal control over financial reporting and to provide processes and controls over the internal communications within KVSB, financial advisors and independent registered public accounting firm. While we have processes to identify and appropriately apply applicable accounting requirements, we plan to enhance these processes to better evaluate our research and understanding of the nuances of the complex accounting standards that apply to our financial statements. We plan to include providing enhanced access to accounting literature, research materials and documents and increased communication among our personnel and third-party professionals with whom we consult regarding complex accounting applications. The elements of our remediation plan can only be accomplished over time, and we can offer no assurance that these initiatives will ultimately have the intended effects. Other than this issue, our disclosure controls and procedures were effective at a reasonable assurance level and, accordingly, provided reasonable assurance that the information required to be disclosed by us in reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms.

Changes in Internal Control Over Financial Reporting

During the quarter ended June 30, 2021, there has been no change in our internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting , as the circumstances that led to the material weaknesses described above had not yet been identified. We are in the process of implementing changes to our internal control over financial reporting to remediate such material weaknesses, as more fully described above. The elements of our remediation plan can only be accomplished over time, and we can offer no assurance that these initiatives will ultimately have the intended effects.

INFORMATION ABOUT NEXTDOOR

Unless the context otherwise requires, all references in this section to the 'Company,' 'we,' 'us,' or 'our' refer to the business of Nextdoor, Inc. and its subsidiaries prior to the consummation of the Business Combination.

183

Nextdoor is the neighborhood network

The simple human truth is that we are all social creatures. We crave connection to the people and places around us. According to an article by Dr. Gillian Sandstrom at the University of Essex, a wider range of relationships - such as a local barista, the host of a neighborhood block party, or the members of a local running group - may contribute to greater sense of belonging. People feel a greater sense of belonging, as well as increased positive affect, after simply having a social interaction with the barista at a coffee shop. Daily interactions with weak ties would be associated with greater social and emotional well-being.

Countless studies show that well-being is higher among people who have regular contact with their neighbors. We need no convincing that this is a reality. According to a Nextdoor global loneliness study, knowing as few as six neighbors reduces the likelihood of feeling lonely and is linked to lower depression, social anxiety, and financial concerns.

Despite the difficulties we have collectively experienced since the start of the COVID-19 pandemic, we have seen neighbors come together time and time again to give and get help. It's been inspiring to see kindness thriving in neighborhoods around the globe.

188

We are confident that using technology to enable real-world connections is possible and makes a difference. Our purpose is what connects all of us at Nextdoor. Our core values are how we bring our purpose to life.

189

Global flywheel of growth

Nextdoor began in the United States, and as of June 30, 2021, our platform was available in 11 countries. Beyond the United States, Nextdoor supports neighborhoods in the United Kingdom, Canada, Australia, Netherlands, France, Spain, Italy, Germany, Sweden, and Denmark. We intend to continue to expand household penetration globally and to increasingly become a weekly and daily use case for our neighbors. As of June 30, 2021, in our top neighborhoods across the world, more than 60% of total Verified Neighbors, who are individuals who join Nextdoor and have their address verified by us, engage with Nextdoor every day.

In addition, other major stakeholders in the neighborhood such as businesses and public agencies also contribute to this flywheel of growth. We see businesses asking neighbors to join and recommend their business. We see public agencies actively recruiting neighbors so that they can be assured that urgent alerts and other messages are getting widespread distribution. These viral growth loops will continue to drive growth and engagement on Nextdoor.

191

Our need to be connected to neighbors was amplified during the pandemic - and that need is real and lasting. For the six months ended June 30, 2021, neighbors who engaged with Nextdoor daily posted 2.1 times more often than in the same prior year period. As the world reopens, consumer behavior is changed for good, with an increased focus on local.

Neighborhoods matter more than ever

Just as people turn to digital networks to enhance their work (e.g., LinkedIn) and play (e.g., Instagram and TikTok), they are looking for a way to do the same in their neighborhood. We believe this is a massive untapped opportunity, and a global phenomenon. As the neighborhood network, Nextdoor is an authentic, purpose driven brand that connects neighbors online and offline.

Strong competitive moat with viral growth loops built in

Our strengths helped us create a new category and give us a competitive advantage:

•Real people: We ensure neighbors are connected to real people by requiring everyone to sign up with their real names and addresses.

192

•Instant distribution: We automatically connect neighbors to everyone nearby so they can build real-world connections. From day to day activities to moments of crisis, neighbors need these local and timely connections - for example to join a walk, gather for a BBQ, find a plumber when a pipe bursts, or help during a hurricane or wildfire. We also instantly connect businesses to customers nearby. Given that most commerce is local, providing hyperlocal reach at scale without needing to build followership is a key differentiator for Nextdoor.

Three distinct audiences

Connecting neighbors to the neighborhood

Connections can include everything from solving an everyday need (e.g., finding a plumber, selling a kid's bike, or finding the best local hike) to being the first line of defense in a crisis (e.g., wildfires, hurricanes, or when an elderly parent with Alzheimer's wanders off).



Welcome	Profiles	Map

When neighbors join Nextdoor, they are prompted to introduce themselves to the neighborhood.	Neighbor profiles help people know the real people they are connecting with and what their interests are.	Neighbors can explore their neighborhood using Maps - to find businesses, events and each other.

193

How neighbors discover what's happening nearby



Newsfeed	Notifications	Search

The Newsfeed is where neighbors find constantly updated posts, discussions, photos, and links from other neighbors and organizations. Neighbors can respond by commenting or adding a reaction (e.g., like, thank, and agree), and can set their feed preferences (e.g., rank by top posts, recent activity, recent posts, or popular everywhere).	In-app Notifications inform neighbors about news, items, and activities they are interested in. Notifications include everything from trending posts to direct messages about items for sale to alerts by local public agencies. Notifications keep neighbors updated in real-time and drive increased engagement on Nextdoor.	Search gives neighbors the ability to find specific content and businesses related to their neighborhood. Nextdoor's search combines an understanding of search terms with filtering capabilities to get neighbors the results they are looking for.

194

How neighbors find local resources



Businesses	Finds	Recommendations

Neighbors visit the Businesses section to discover spots most-loved by locals, find exclusive deals and promotions, and interact with business owners' updates. As of June 30, 2021, neighbors had left more than 50 million business recommendations on Nextdoor.	Finds is our truly local marketplace where neighbors buy, sell, or give away items, and even offer services such as babysitting and dog walking. The number of listings on Finds increased 47% in 2020 versus 2019, and the total value of goods listed in 2020 reached nearly $20 billion.	Neighbors can reach out to those who know best for recommendations nearby. Neighbors can find the best spice shop, hair salon, or landscaping business from a truly local perspective. They can give and get help for anything they need in the neighborhood.

195

How neighbors connect with other neighbors



Groups	Messaging	Posts/Comments

Neighbors create Groups to connect with those nearby with a common interest. Examples include San Antonio Backyard Gardeners, Opossums R Our Friends in Kansas City, and We ❤ Black Business in London. We see a significant incremental lift in engagement after a neighbor engages with a group.	Neighbors can contact other neighbors and organizations through direct messaging (e.g., neighbors messaging businesses, coordinating a time to pick up a desk, to borrow a printer, or get more information about a tutor).	Through Posts and Comments neighbors can reach out to the neighborhood to get and give information that is locally relevant, trusted, and in real time. Whether it is for a local plumber or a family friendly pizza restaurant, neighbors know best.

Connecting businesses to their customers

Businesses of all sizes come to Nextdoor to reach their customers in meaningful ways. Large brands use our platform to deliver hyperlocal targeting and personalization of advertising at scale. Small businesses rely on Nextdoor to reach customers with information that encourages action.

196

How large brands reach their customers



Sponsored Post in Newsfeed	Sponsored Post In-App Digest	Sponsored Post in Finds

Large brands use Sponsored Posts in the Newsfeed to build awareness. Ads are featured prominently where neighbors first look for what is happening on Nextdoor. Ads can also be customized with neighborhood name and store location to make them even more relevant.	Large brands can also use Sponsored Posts in the In-App Digest to create awareness among neighbors who turn to their summary of top posts. Ads are highly visible, and neighborhood names and store locations can be customized by neighborhood.	Large brands can leverage Sponsored Posts in Finds to drive action such as shop now. Our local marketplace is where neighbors with high intent to buy will go. Ads are given a top spot in this contextually relevant space with the opportunity to customize by neighborhood.

197

How small businesses reach their customers



Neighborhood Sponsorships	Local Deals

Small businesses leverage Neighborhood Sponsorships to drive awareness, build a positive reputation, and keep their business top of mind. With these sponsorships they create and distribute automated ad placements that regularly post to the newsfeed in targeted ZIP codes.	Small businesses and neighbors offering services use Local Deals to target specific neighborhoods and drive sales. Designing specific timely discounts and promotions for specific neighborhoods engages and motivates their best customers, those nearby.

Connecting public agencies to their constituents

Public agencies come to Nextdoor to deliver critical information to neighbors with hyperlocal distribution. They also leverage Nextdoor to find out what is important to their constituents and communicate with them directly. This includes keeping neighbors apprised about everything from local events such as webinars and street fairs, to timely safety updates and urgent alerts and tips to staying safe and protected, for example messaging on power outages, storms, or wildfires.

198

How public agencies keep constituents informed



Emergency Alerts	Respond to Questions	Education

Public agencies use our platform to post real-time, geo-targeted alerts to inform neighbors in need.	Agency employees are able to manage content and respond to questions from the neighbors in their area.	Agencies can keep the neighbors in the areas they serve, up to date on information and education relevant to them.

199

Strong business model with a unique selling proposition

Organizations including large brands, small and mid-sized businesses, public agencies, and nonprofits are a valuable part of the neighborhood ecosystem and neighbors want to engage and be connected to them. Neighbors come to Nextdoor with a local mindset where they are ready to find or share recommendations, and take action. Everything in our Newsfeed has contextual relevance based on neighborhood boundaries. From building awareness to driving sales, we offer organizations of all sizes distinct and differentiated products that allow them to reach the right neighbor, at the right time, with the right message. Today we focus primarily on customers in home services, financial services, telco, retail, consumer packaged goods, healthcare, auto, and entertainment. However, over time, we believe we can expand to an even broader set of verticals as our product and go-to-market capabilities improve.

Each social link on Nextdoor is highly valuable because most commerce is local. For our customers, Nextdoor neighbors also tend to be in an advertiser-friendly demographic: as of December 2020, 61% were women, 93% were over 25 years old, 79% were homeowners, and they had a median annual income of $90,000. Furthermore, as noted above, according to Brightpearl, 75% of neighbors plan to shop more locally - in their neighborhoods.

Our solutions set help businesses reach their goals.

•High relevance. Neighbors on Nextdoor share something in common - a connection to their neighborhood. Because of this, neighbor content is highly relevant to the locality in which it is placed and provides a unique environment for our customers to place their message - with the ability to reach across varying demographics and geographies.

•Neighborhood level data provides actionable insights. We have a unique ability to understand consumer behavior and trends from a national to a neighborhood level. In March 2020, we launched our proprietary Nextdoor Insights Series, showcasing U.S. neighborhood trends. For example, our first quarter 2021 report showed neighbors over-indexed on interest in Do-It-Yourself/home improvement in 2020, and were more likely to purchase furniture in the past six months. First quarter 2021 queries also showed three of the top

206

five neighbor queries are plumber, handyman, electrician - suggesting the interest remains. And a 2020 report showed top home service searches by state: lawn services in Iowa and Missouri and snow removal services in North Dakota and Maine. Our trove of data can provide valuable insights to our customers to help them better serve their customers.

•Hyperlocal targeting and customization.Businesses can reach neighbors both locally and with local customization at scale. We are able to dynamically update ad creatives to run nationally with local updates, such as neighborhood names or store locations, to create meaningful connections between our customers and neighbors.

•Timely reach with high intent audiences.Neighbors often come to Nextdoor looking for a real-time solution nearby. This creates an attractive environment for our customers. For example, during Halloween 2020, Hershey used Nextdoor to tap into the impulse behavior of neighbors. Simply sharing popular candies and chocolate, Hershey was able to significantly increase add-to-cart and sales, surpassing their benchmark by 140%.

A kind platform

Nextdoor is a leading innovator in creating a kind platform that facilitates healthy neighborhood connections and conversations. We set clear guidelines, and use a combination of people and technology to encourage the behaviors that support our purpose of cultivating a kinder world where everyone has a neighborhood they can rely on.

From day one, we've ensured that Nextdoor neighborhoods are made up of real people, nearby. We require all new neighbors to accept our Good Neighbor Pledge upon joining, in order to introduce our community guidelines and provide personal accountability for interactions on the platform. If these guidelines are violated, neighbors are able to report the inappropriate behavior.

We rely on a combination of technology and human review to effectively moderate the platform. We've always believed it's important to incorporate local context into moderation decisions, which is why we've built our community volunteer programs to empower thoughtful neighborhood moderation. Review of potentially harmful content (i.e. misinformation, discrimination) and inappropriate neighbor behavior is always handled by Nextdoor staff to ensure consistency.

Volunteer moderators are supported in their efforts with specialized tools, and access to resources and training - including an online course designed to help recognize and address bias in online discourse. We recently expanded our volunteer tool set to better foster a welcoming and inclusive community. Our Welcome teamvolunteers are alerted when a new neighbor joins, so they can reach out with a message of connection and belonging to establish rapport. Building community is at the core of Nextdoor which is why we continue to add volunteer programs that reinforce vibrant, active communities that are safe, civil, and nurture a place where everyone feels like they belong.

A great deal of social science has developed over the last century on the topic of connection and belonging. As such, we work regularly with leading experts on our Neighborhood Vitality Advisory Board to refine our community guidelines, iterate on our features and tools, and develop teams that further our innovative stance on creating a kind platform.

213



Neighbor Pledge	Kindness Reminder	Moderation Tools

All neighbors must agree to the Good Neighbor Pledge upon joining. We also make our community guidelines transparent, understandable, and easy to find. These guidelines define the community values and explicitly forbid racism, discrimination, misinformation, and other harmful types of content.	Our Kindness Reminder detects language that may potentially violate our community guidelines, and encourages the author to edit their content before they publish. This prompt, developed in conjunction with social scientist and Biasedauthor Dr. Jennifer Eberhardt, resulted in a 30% reduction in uncivil content over a three month period in 2019.	Our moderation system relies on people and technology. The product enables neighbors to report harmful content, and neighborhood volunteers use in-product tools to vote whether the reports violate community guidelines. Harmful content, e.g. misinformation of discrimination, is escalated to our trained Neighborhood Operations staff for appropriate action.

Large and growing total addressable market

The total global digital advertising market for consumers was estimated at $355 billion in 2020, growing by 71% to $607 billion in 2024. This estimate is based on data from eMarketer and excludes 6% of digital advertising spend which is, by our estimation, business-to-business spend and which Nextdoor does not address.

The total digital advertising market for consumers in the United States was estimated at $143 billion in 2020, growing by 83% to $262 billion in 2024.

Given the structural changes in consumer behavior post pandemic (e.g hybrid work from home / from office models or completely working from home, a stronger affinity for supporting local businesses) we believe that more

214

of the digital advertising market will have a local orientation. This combined with our ability to increase the return on investment for customers on our platform makes our value proposition even stronger.

We are investing in highly engaging ad formats such as video and maps, self-serve advertising capabilities, measurement tools, and our sales force, media agency partnerships, and channel partners to capture a greater share of digital advertising spend.

Over time, we believe we can build new revenue streams in addition to advertising. This includes potential monetization opportunities from our Finds marketplace. Furthermore, because many neighbors on our platform come to Nextdoor to get things done locally, including purchasing goods and services available nearby, we believe we have a large opportunity to provide a venue for local commerce on our platform. Other potential areas that may increase our total addressable market include home services, real estate, and local events.

Growth strategies with powerful network effects

Our neighborhood ecosystem has unique network effects online and offline that strengthens as we scale. The more neighbors join our neighborhood networks, the more content they create, the more valuable the experience becomes, encouraging more neighbors to join. This transfers into the real world, making these connections even more lasting. As more neighbors learn about and join Nextdoor, more brands, businesses and public agencies join to reach them, further enhancing the overall experience. These powerful network effects make Nextdoor more and more valuable as we grow.

We are focused on the following growth strategies:

•Increase neighbors on our network. As of June 30, 2021, we had nearly 47 million claimed households (defined as a household with at least one Verified Neighbor) worldwide. Reaching total penetration in-line with our top quartile U.S. neighborhoods would increase our reach to over 200 million households. To date, we have primarily grown organically, with neighbors inviting other neighbors to connect through word of mouth, email invitations, and mailed invites. Our share of organic traffic has increased as our platform has grown. In 2020, 68% of our new registered neighbors were acquired through organic and unpaid channels, up from 46% in 2019. To continue our momentum and expand our network, we are focused on product-driven growth and global growth.

Our product-driven growth centers around enabling an active valued community, making it easy to discover our platform, invite others to join Nextdoor, and share content. We believe that allowing neighbors to access and discover neighborhood content through online search will drive fast understanding and adoption of our platform. We are adding features such as contact sync which will make it easier for neighbors to invite their friends and family onto Nextdoor. And, making content sharing a more expansive and seamless experience for content creators will encourage new neighbors to join Nextdoor.

Our global growth builds on the successes we have seen in markets outside of the United States. We are still in the early stages of global expansion and will continue to focus on growth in our current international markets, as we evaluate expansion opportunities in additional geographies.

•Increase engagement on our platform. We know once a neighbor joins and experiences the utility and delight of Nextdoor, they are likely to stay. As previously stated, as of June 30, 2021, our three month neighbor retention was 76%. To reinforce an active, valued community, our product-driven growth will focus on inspiring neighbors already on the platform to be fully engaged participants.

We will continue to invest in making it easier to engage, share interests, and create meaningful connections. Creating simple and seamless ways to share conversations, videos, and polls will increase content creation and contribution. Artificial Intelligence ('AI') tools will provide automatic responses to the right messages at the right time to encourage more engagement. And, improved search and find capabilities will allow greater access to topics with real time interest. At the same time, allowing neighbors to follow multiple neighborhoods will multiply the reasons to engage on Nextdoor.

215

•Increase monetization on our platform. We are still in the early stages of monetization on our platform and believe there are many vectors for sustained revenue growth. In particular, we are focused on two areas - scaling our advertising business and developing new revenue streams.

Scaling our advertising business involves further improving advertising products and tools, organizing and growing our salesforce, and investing in media agency and channel partner relationships. We are continuing to invest in our self-serve advertising platform which will improve ad relevance and decisioning. Customers will have greater control and transparency, as well as improved measurement. Our self-serve platform will also allow for programmatic advertising. We intend to gain efficiencies in scaling, and be able to focus our salesforce on attracting and retaining larger brands, with opportunities to upsell and partner with them in more meaningful ways. And, with a focus on building media agency relationships, we believe we will gain access to more customers.

Ongoing product investments will allow us to enable and capture potential new revenue in local commerce for goods and services.

Philanthropy

As a purpose driven company, we have started the process of forming the Nextdoor Kind Foundation. The goal of this 501(c)(3) nonprofit foundation is to enable neighbors who want to improve their neighborhoods and lack the funding for their project - whether it is planting a community garden, setting up a sharing tool shed or hosting a neighborhood gathering. Given that Nextdoor brings neighbors together, helps them build relationships so they can get things done, access to capital is yet another step in Nextdoor enabling our purpose.

To that end, following the merger, Nextdoor CEO Sarah Friar, Co-Founders Nirav Tolia, Sarah Leary and Prakash Janakiraman, and founding investor J. William Gurley will each contribute a portion of their personal ownership in Nextdoor to form and sustainably fund the Nextdoor Kind Foundation, a nonprofit foundation dedicated to helping neighbors rejuvenate their neighborhoods through targeted grants.

Technology

Our investments in technology are focused on the following areas: Core Product Development, Business Solutions, and Cloud Infrastructure.

•Core product development. Our product organization focuses on creating and improving products for all our neighbors in the countries in which we operate around the world. Our platform powers hundreds of thousands of neighborhood networks and all the entities that form these neighborhoods across neighbors, businesses, and public agencies. Using machine-learning and proprietary technology, we enable locally relevant conversations, keeping neighbors informed and connected while nurturing civil and kind discussions with solutions like the Neighbor Pledge and the Kindness Reminder.

•Business solutions.Our proprietary Nextdoor Ad Manager ('NAM') is at the heart of our business solutions, powering our advertising products, advertising technology stack and reporting capabilities. Built with flexibility and modularity at its core, NAM consists of shared targeting, auction, and delivery engines. These capabilities serve all of our customers, ranging from large brands to small business owners. NAM also uses first-party data captured from the billions of daily actions on Nextdoor combined with proprietary neighborhood mapping data from our platform to create differentiated and hyperlocal audience data.

•Cloud infrastructure.We continually invest in the underlying technology platform that powers all of our products and services. From its inception, our infrastructure was built to be cloud-native, applying well-tested design patterns with distributed systems that are linearly scalable and highly flexible. We partner with Amazon Web Services ('AWS') as our preferred cloud services provider to support our growing platform needs. We enable our engineering resources to focus on improving the products for our neighbors on Nextdoor.

216

•Development principles. Execution velocity and autonomy are critical pillars of our engineering culture. We employ agile development processes and techniques combined with continuous integration ('CI') and continuous deployment ('CD') to empower our teams to rapidly improve our products and the platforms that power them.

Leveraging data generated by usage of our products is a first principle in how we develop, test, and iterate to continually improve the user experience and inform our future product roadmap.

In addition, we build our products to be global-ready and mobile first, with the majority of our neighbors using our iOS and Android mobile apps to interact with our products.

Intellectual property

Our intellectual property and core technological innovations are integral components of our business. To establish and protect our intellectual property, proprietary rights and brand, we rely on a combination of federal, state, and common-law rights in the United States and the rights under the laws of other countries, patents, trademarks, copyrights, domain name, trade secrets, including know-how, license agreements, confidentiality procedures, non-disclosure agreements with third parties, employee disclosure, and invention assignment agreements, and other contractual rights.

We own a trademark portfolio, including registered trademarks and applications in the United States and other countries, for the marks NEXTDOOR, , and . We have registered domain names that we use in or relate to our business, such as the domain name and country code top level domain name equivalents. As of June 30, 2021, we had seven issued patents and five filed patent applications in the United States and certain other foreign countries. We cannot assure you that any of our patent applications will result in the issuance of a patent or whether the examination process will require us to narrow our claims. Additionally, our current and future patents, trademarks, and other intellectual property or other proprietary rights may be contested, circumvented or found unenforceable or invalid. We may not be able to obtain or maintain sufficient protection for or successfully enforce our intellectual property. We license content, technology, and other intellectual property from our partners, and rely on our license agreements with those partners to use the intellectual property. Third parties may assert claims related to intellectual property rights against our partners or us.

For additional information, please see the section entitled 'Risk Factors - Risks Related to Intellectual Property.'

Employees

Community is at the heart of Nextdoor and our growing community of employees is our lifeblood. They are a group of diverse, talented, empathetic people who we are honored to call teammates. The wide ranging experiences and perspectives they draw from fuels our efforts to build a global platform that helps cultivate a kinder world where everyone has a neighborhood they can rely on.

As of June 30, 2021, we had 565 full-time employees located in cities around the world.

Competition

We compete in almost every aspect of our business with companies that provide a variety of internet products, services, content, and online advertising, including Facebook, Google, Pinterest, Snap, and Twitter. In addition, aspects of our platform compete with other products and services, including real estate, classifieds, and recommendation and search engines. We compete with these companies to attract, engage, and retain users and to attract and retain advertisers. As we introduce new products, as our platform evolves, or as other companies introduce new products and services, we may become subject to additional competition in other countries.

While our industry is evolving rapidly and is becoming increasingly competitive, we believe that we compete effectively due to our singular focus on creating and strengthening our neighborhood networks, the size and engagement of our user base, our ability to provide neighbors with trusted information from a uniquely local

217

perspective, our value proposition to advertisers including businesses and public agencies, and our powerful network effects.

At its core, Nextdoor is the local graph. Our strengths are real people, hyperlocal proximity, trusted information, local perspective and instant distribution, each of which reinforce each other to create a strong competitive moat.

For additional information, see the section entitled 'Risk Factors - Nextdoor's business is highly competitive. Competition presents an ongoing threat to the success of Nextdoor's business.'

Government regulation

We are subject to many U.S. federal and state and foreign laws and regulations that involve matters central to our business, including laws and regulations that involve data privacy and data protection, intellectual property (including copyright and patent laws), content, rights of publicity, advertising, marketing, competition, protection of minors, consumer protection, taxation, and telecommunications. These laws and regulations are constantly evolving and may be interpreted, applied, created, or amended, in a manner that could harm our business.

We rely on a variety of statutory and common-law frameworks and defenses relevant to the content available on our service, including the Digital Millennium Copyright Act, the Communications Decency Act ('CDA') and the fair-use doctrine in the United States, and the Electronic Commerce Directive in the European Union. However, each of these statutes is subject to uncertain or evolving judicial interpretation and regulatory and legislative amendments. For example, in the United States, laws such as the CDA, which have previously been interpreted to provide substantial protection to interactive computer service providers, may change and become less predictable or unfavorable by legislative action or juridical interpretation. There have been various federal and state legislative efforts to restrict the scope of the protections available to online platforms under the CDA, in particular with regards to Section 230 of the CDA, and current protections from liability for third-party content in the United States could decrease or change. We could incur significant costs investigating and defending such claims and, if we are found liable, significant damages.

The European Union is also reviewing the regulation of digital services, and has introduced the Digital Services Act ('DSA') a package of legislation intended to update the liability and safety rules for digital platforms, products, and services, which could negatively impact the scope of the limited immunity provided by the E-Commerce Directive. Some European jurisdictions and the United Kingdom have also proposed or intend to pass legislation that imposes new obligations and liabilities on platforms with respect to certain types of harmful content. While the scope and timing of these proposals are currently uncertain, if the rules, doctrines or currently available defenses change, if international jurisdictions refuse to apply similar protections that are currently available in the United States or the European Union or if a court were to disagree with our application of those rules to our service, we could be required to expend significant resources to try to comply with the new rules or incur liability, and our business, revenue, and financial results could be harmed.

We receive, process, store, use, and share data, some of which contains personal information. We are therefore subject to U.S. federal, state, local, and foreign laws and regulations regarding data privacy and the collection, storage, sharing, use, processing, disclosure and protection of personal information and other data from users, employees or business partners, and we currently, and from time to time, may not be in technical compliance with all such laws. Current or future legislation or regulations in the United States and other jurisdictions, or new interpretations of existing laws and regulations, could significantly restrict or impose conditions on our ability to collect, store, augment, analyze, use, and share data or increase consumer notice or consent requirements before a company can utilize advertising technologies. For example, in Europe, the General Data Protection Regulation ('GDPR'), and in the United Kingdom, the UK General Data Protection Regulation and UK Data Protection Act 2018, apply to our collection, control, processing, sharing, disclosure and use of personal data. The GDPR and UK GDPR impose strict data protection compliance regimes and include significant penalties for non-compliance. In the United States, the California Consumer Privacy Act ('CCPA') which took effect in January 2020, also establishes certain transparency rules and creates new data privacy rights for users, including rights to access and delete their personal information and new ways to opt-out of certain sales or transfers of their personal information, and provides users with additional causes of action. Additionally, California recently voters approved a new privacy law,

218

the California Privacy Rights Act ('CPRA'). Effective starting on January 1, 2023 (with a look back to January 2022), the CPRA will significantly modify the CCPA, including by expanding consumers' rights with respect to certain sensitive personal information. The CPRA also creates a new state agency that will be vested with authority to implement and enforce the CCPA and the CPRA. Similarly, there are a number of legislative proposals in the European Union, the United States, at both the federal and state level, as well as other jurisdictions that could impose new obligations or limitations in areas affecting our business. In addition, Virginia and Colorado enacted the Virginia Consumer Data Protection Act and the Colorado Data Protection Act, respectively, which have similar requirements and obligations to the CCPA.

The costs of complying with these laws and regulations, which in some cases can be enforced by private parties in addition to government entities, are high and likely to increase in the future, particularly as the degree of regulation increases, our business grows and our geographic scope expands. Further, the impact of these laws and regulations may disproportionately affect our business in comparison to our peers in the technology sector that have greater resources. Any failure on our part to comply with these laws and regulations may subject us to significant liabilities or penalties, or otherwise adversely affect our business, financial condition or operating results. Further, it is possible that certain governments may seek to block or limit our products or otherwise impose other restrictions that may affect the accessibility or usability of any or all our products for an extended period of time or indefinitely.

We communicate with lawmakers and regulators in the countries and regions in which we do business. We have a dedicated policy team that monitors legal and regulatory developments and works with policymakers and regulators around the world to help ensure that our perspective is heard in matters of importance to us.

For additional information, see the section entitled 'Risk Factors - Risks Related to Legal and Regulatory Matters.'

Facilities

We are headquartered in San Francisco, California and maintain offices in various international locations. All of our facilities are leased. We intend to procure additional space in the future as we continue to add employees and expand geographically. We believe that our current facilities are adequate to meet our current needs and that, should it be needed, suitable additional or alternative space will be available to accommodate our operations.

Legal proceedings

From time to time, we may be subject to legal proceedings and claims in the ordinary course of business. We are not presently a party to any legal proceedings that, if determined adversely to us, would individually or taken together have a material adverse effect on our business or financial results. We have received, and may in the future continue to receive, claims from third parties relating to information or content that is published or made available on our platform, among other types of claims. Our platform relies upon content that is created and posted by neighbors or other third parties. Although content on our platform is typically generated by third parties, and not by us, claims of defamation, disparagement, intellectual property infringement, or other alleged damages could be asserted against us, in addition to our neighbors and customers. Future litigation may be necessary to defend ourselves, our partners, and our customers by determining the scope, enforceability, and validity of third-party proprietary rights, or to establish our proprietary rights. The results of any current or future litigation cannot be predicted with certainty, and regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors.

NEXTDOOR'S MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Unless the context otherwise requires, all references in this section to 'we', 'us' or 'our' refer to the combined business of Nextdoor, Inc. and its consolidated subsidiaries (collectively, 'Nextdoor') prior to Closing.

The following discussion and analysis provides information which Nextdoor's management believes is relevant to an assessment and understanding of Nextdoor's consolidated results of operations and financial condition. The discussion should be read together with 'Selected Historical Financial Data of Nextdoor' and the historical consolidated financial statements as of December 31, 2020 and 2019 and for the years ended December 31, 2020 and 2019 and unaudited interim condensed consolidated financial statements as of June 30, 2021 and the six-month periods ended June 30, 2021 and 2020, and the related notes that are included elsewhere in this proxy statement/prospectus. The discussion and analysis should also be read together with the pro forma financial information as of and for the six months ended June 30, 2021 and for the year ended December 31, 2020. See the section entitled 'Unaudited Pro Forma Condensed Combined Financial Information.' This discussion may contain forward-looking statements based upon current expectations that involve risks and uncertainties. Nextdoor's actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under 'Risk Factors' or in other parts of this proxy statement/prospectus.

Overview

Since our founding, we have had a singular focus on developing our neighborhood network. As of June 30, 2021, Nextdoor was in more than 280,000 neighborhoods around the world. In the United States, nearly 1 in 3 households turn to Nextdoor to receive trusted information, give and get help, and build real-world connections with people and organizations nearby - including neighbors, small and mid-sized businesses, large brands, public agencies, and nonprofits. Nextdoor is the neighborhood network that brings all of these stakeholders together to get things done locally and build thriving communities.

Nextdoor began in the United States, and as of June 30, 2021, our platform was available in 11 countries. Beyond the United States, Nextdoor supports neighborhoods in the United Kingdom, Canada, Australia, Netherlands, France, Spain, Italy, Germany, Sweden, and Denmark. Our sole focus on neighborhoods has allowed us to introduce a range of innovative products and features that drive continuous neighbor acquisition and growth in engagement. As a result, we are increasing neighborhood penetration, and increasingly becoming a weekly and even

221

daily use case. In top neighborhoods across the world we see more than 60% of total neighbors engaging daily on our platform.

Nextdoor is a community built on trust and genuine connections. Initially, our priority was to grow our neighborhood network across the United States by adding users that we define as Verified Neighbors, who are individuals who join Nextdoor and have their address verified by us. By requiring neighbors to use their real name and address, we ensure that conversations and interactions on Nextdoor are between real people creating trust and mutual accountability.

To date, we have primarily attracted new neighbors through word-of-mouth, earned media, and through mailed invitations, and kept our content accessible only to Verified Neighbors. While we believe this approach was critical to develop our trusted platform, it also constrained our user growth relative to the total market opportunity. More recently, we have begun investing in new features to inspire neighbors to increase engagement, such as the ability to follow multiple neighborhoods, join interest groups, and make moments more engaging and shareable with enhanced video capabilities.

We took a similarly deliberate approach to our monetization efforts. We serve customers who consist of large brands and small and mid-sized businesses seeking to provide hyperlocal, engaging advertising content to our large and engaged base of neighbors. In 2016, we started to build a sales force to target large brands. We have since developed a range of advertising products that allow our customers to reach neighbors at every stage of the advertising funnel, starting with discovery, onto consideration, and ending with purchase. In 2017, we started to offer Neighborhood Sponsorships to allow businesses to build a reputation, drive awareness, and keep their business top of mind by advertising in the Nextdoor Newsfeed. Our first customers for this product were real estate agents who created automated ad placements to post to the Nextdoor Newsfeed in targeted postal codes. We have since introduced Neighborhood Sponsorships across a range of verticals and have further expanded our offering to include Local Deals and Local Search. More recently, we have been investing in building new advertising products, self-serve tools, and measurement capabilities that allow us to further deliver value to our customers. Our enterprise advertising customers, which currently make up our largest share of revenue, span a wide variety of industry verticals. For the six months ended June 30, 2021, Financial Services, Home Services, Home Improvement, Cable, Technology and Communications, and Home Security represented our five largest enterprise verticals. For the six months ended June 30, 2021, no single enterprise industry vertical made up more than 10% of our total revenue.

222

As our base of neighbors and customers has grown, we have benefited from powerful network effects. As neighborhood penetration increases, engagement also increases through additional relevant local content that is generated by neighbors on Nextdoor, prompting more engagement from other neighbors, which then leads to higher retention and increasing value for all who are in our network. Once a neighbor joins and experiences the value of Nextdoor, they are very likely to stay and engage with our platform. Historically, we have enjoyed strong user retention, with 76% of Verified Neighbors remaining active on our platform after 3 months, 67% after 6 months, 59% after 12 months, and 57% after 24 months. Our retention rate only includes neighbors who were active in the last 30 days of the period for which our retention rate is calculated. We believe that this strong user retention is due to the utility and community connections that our platform offers neighbors who come to our platform to access trusted information, build real-world connections with those nearby, and get things done locally. Additionally, increases in neighbor reach and engagement enhance the value we offer to customers, leading to improved retention and additional revenue opportunities for us.

We have grown rapidly since our inception. For the six months ended June 30, 2021 and June 30, 2020, we generated revenue of $80.2 million and $51.3 million, respectively, representing year-over-year growth of 56%. For the years ended December 31, 2020 and 2019, we generated revenue of $123.3 million and $82.6 million, respectively, representing year-over-year growth of 49%. We have made significant investments in our platform. Accordingly, we have a history of generating net losses. For the six months ended June 30, 2021, we generated a net loss of $(46.6) million and Adjusted EBITDA of $(28.1) million, as compared to a net loss of $(41.1) million and Adjusted EBITDA of $(30.4) million, respectively, for the six months ended June 30, 2020. For the year ended December 31, 2020, we generated a net loss of $(75.2) million and Adjusted EBITDA of $(50.2) million, as compared to a net loss of $(73.3) million and Adjusted EBITDA of $(58.8) million, respectively, for the year ended December 31, 2019. See 'Management's Discussion and Analysis of Financial Condition and Results of Operations-Non-GAAP Financial Measure' below for more information and for a reconciliation of net loss, the most directly comparable financial measure calculated and presented in accordance with GAAP, to Adjusted EBITDA.

Key Business Metrics and Non-GAAP Financial Measure

In addition to the measures presented in our consolidated financial statements, we use the following key business metrics to evaluate our business, measure our performance, develop financial forecasts, and make strategic decisions.

Key Business Metrics

Weekly Active Users (WAUs)

We define a Weekly Active User, or WAU, as a Nextdoor user who opens our application, logs on to our website, or engages with an email with monetizable content at least once during a defined 7-day period. We calculate average WAUs for a particular period by calculating the count of unique users, on a rolling basis for the past seven days, for each day of that period, and dividing that sum by the number of days in that period. We assess the health of our business by measuring WAUs because we believe that weekly usage best captures the cadence at which we expect a healthy user base to engage with, and derive the most utility from our platform, and by extension their neighborhood. We also present WAUs by geography because we are more advanced in engagement and monetization in the United States than internationally.

In June 2021, Apple announced changes to be introduced to the Apple email client available on its operating systems, including iOS 15, iPadOS 15, and macOS 12, expected to be released in September 2021, including changes which will limit our ability to measure user engagement with emails containing monetizable content for users that use the Apple email client. The introduction of these changes will impact our ability to accurately calculate a portion of WAUs for periods following the adoption of the updated operating systems. Following this introduction, we intend to use estimates for these user engagement numbers based on historical data sets, as well as data from users who engage with Nextdoor's monetizable content on email clients other than Apple email.

Our WAU for the years ended December 31, 2020 and 2019 was 26.7 million and 19.5 million, respectively. We saw a significant increase in WAUs in the second quarter of 2020, partly due to individuals turning to Nextdoor as a trusted source of information as well as to offer help to other neighbors during the COVID-19 pandemic. Since

223

that quarter, engagement as measured by WAUs has generally remained steady as users have returned to our platform for the utility that it offers them. As illustrated below, our international WAUs have grown at a faster rate than our U.S. WAUs, and we expect this international growth to continue to outpace U.S. growth in the near term.

Quarterly Average Weekly Active Users

(in millions)

224

A portion of our WAUs visit Nextdoor on a daily basis. We define a daily active user ('DAU') as a Nextdoor user who opens our application, logs on to our website, or engages with an email with monetizable content at least once during a defined 24 hour period. The proportion of DAUs to WAUs has generally increased over time as our users have increased their engagement with our platform. In 2020, the proportion of global DAUs to WAUs was 52%, up from 47% in 2019. For the six months ended June 30, 2021, the proportion of global DAUs to WAUs was 52%, consistent with the six months ended June 30, 2020.

Average Revenue per Weekly Active User (ARPU)

We generate revenue primarily from advertising. We measure monetization of our platform through our average revenue per weekly active user, or ARPU, metric. We define ARPU as our total revenue in that geography during a period divided by the average of the number of WAUs in that geography during the same period. We present ARPU on a U.S. and international basis because we are more advanced in our monetization in the United States than internationally.

U.S. ARPU is higher primarily due to our decision to focus our earliest monetization efforts there, the size and maturity of our audience in the United States, as well the size of the U.S. advertising market. For purposes of calculating ARPU, revenue by user geography is apportioned to each region based on a determination of the location of the account where the revenue-generating activities occur. Our ARPU for the years ended December 31, 2020 and 2019 was $4.62 and $4.23, respectively. Our ARPU reflects the seasonality of our advertising revenue, with the fourth quarter typically being the strongest quarter of each year.

Quarterly Average Revenue per User

225

Non-GAAP Financial Measure

Adjusted EBITDA

Adjusted EBITDA is a non-GAAP financial measure that represents our net loss adjusted for depreciation and amortization, stock-based compensation, net interest income, provision for income taxes, and acquisition-related costs.

We use Adjusted EBITDA in conjunction with GAAP measures as part of our overall assessment of our performance, including the preparation of our annual operating budget and quarterly forecasts, to evaluate the effectiveness of our business strategies and to communicate with our board of directors concerning our financial performance. We believe Adjusted EBITDA is also helpful to investors, analysts and other interested parties because it can assist in providing a more consistent and comparable overview of our operations across our historical financial periods. Adjusted EBITDA has limitations as an analytical tool, however, and you should not consider it in isolation or as substitutes for analysis of our results as reported under GAAP. Because of these limitations, you should consider Adjusted EBITDA alongside other financial performance measures, including net loss and our other GAAP results. In evaluating Adjusted EBITDA, you should be aware that in the future we may incur expenses that are the same as or similar to some of the adjustments in this presentation. Our presentation of Adjusted EBITDA should not be construed to imply that our future results will be unaffected by the types of items excluded from the calculation of Adjusted EBITDA. Adjusted EBITDA is not presented in accordance with GAAP and the use of this term varies from others in our industry.

The following is a reconciliation of Adjusted EBITDA to the most comparable GAAP measure, net loss:


Six Months Ended June 30,	Years Ended December 31,
(in thousands)	2021	2020	2020	2019
Net loss	$	(46,639)	$	(41,132)	$	(75,234)	$	(73,281)

Factors Affecting Our Performance

Growth in and Engagement of Users.We measure growth in, and engagement of, users by tracking WAUs and Verified Users (which we also refer to as Verified Neighbors). As the size and engagement of our user base grows, we believe the potential to increase our revenue grows.

We attract users through several channels including word-of-mouth, mailed invitations, email and text invitations, and our contact sync feature. During 2020, 68% of our new Verified Users were acquired through organic and unpaid channels. We complement our organic growth with paid marketing, which primarily focuses on newer neighborhoods where we have lower levels of penetration and are focused on growing our user base. This includes neighborhoods in international countries where we are in earlier stages of growth.

We may face challenges increasing the size and engagement of our user base due to a number of factors including competition, challenges in acquiring and engaging users, or changes in regulations.

Growth in Monetization.Monetization trends, which are reflected in our ARPU, are a key factor that affects our revenue and financial results. We are in the early stages of our monetization efforts. To increase monetization, we are focused on serving more national brands by building out our salesforce, and enhancing our self-serve tools for our customers. We are also focused on increasing our user base and engagement in the United States and internationally, which will increase the opportunities for businesses to advertise on Nextdoor.

There are many variables that impact ARPU, including the number of ad impressions shown on our platform and the price per ad, which depends on a number of factors including the engagement of our user base, the number and diversity of our customers, seasonality of advertising spend, our customers' advertising objectives, advertising performance, the effectiveness of our advertising products, our ability to measure that effectiveness for our customer, and the effect of geographic differences on each of these factors.

Due to our decision to focus our earliest monetization efforts in the United States, we have less experience monetizing international markets and therefore may experience challenges scaling and monetizing these markets. The international advertising market is also less mature than the U.S. digital advertising market.

Investment for Growth.We intend to continue to invest in technology that we believe will enhance user and customer experiences. We also intend to continue to invest heavily in our advertising products, including our self-serve advertising platform and first-party and third-party ad measurement tools, as well as our sales team. Our ability to grow our user base, attract new advertisers, increase our revenue, and expand our total addressable market will depend, in part, on our ability to continue innovating.

International Expansion. Our early proof points from launches in 10 countries outside of the United States show user engagement across international markets on par with the U.S. market. We believe that increased international monetization presents an important opportunity for growth, and we are working on localizing our product and expanding our operations to better serve our international user and customer base. We are still in the early stages of global expansion and will continue to evaluate expansion opportunities in our current international markets, and also in additional geographies. Over time, we believe that international WAUs can grow rapidly. We also believe that we can increase the monetization of users in international markets and that we can increase long-term ARPU for international WAUs from current levels. While we expect to grow ARPU for international WAUs, we still expect this to be lower than ARPU for U.S. WAUs. We expect that our international expansion will require significant investment. Although our investments in international expansion may adversely affect our operating results in the near term, we believe that they will contribute to our long-term growth. If our near-term investments do not lead to increased international WAUs and ARPU and expected revenue growth over time, we may not achieve or, if achieved, maintain profitability and our growth rates may slow or decline.

Seasonality.Industry advertising spend tends to be strongest in the fourth quarter, and we observe a similar pattern in our historical revenue. Our significant growth has partially masked these trends in historical periods, and we expect seasonality to become more pronounced in the future.

227

Components of Results of Operations

Revenue

We generate substantially all of our revenue from the delivery of advertisements on our platform which includes the delivery of advertising impressions sold on a cost per thousand, or CPM, basis and cost per click, or CPC, basis, as well as local sponsorships and local deals which are sold on a fixed-fee basis. The majority of our revenue is generated in the United States.

Cost of Revenue

Cost of revenue consists primarily of expenses associated with the delivery of our revenue generating activities, including the third-party cost of hosting our platform and allocated personnel-related costs, which include salaries, benefits, and stock-based compensation for employees engaged in development of our revenue generating products. Cost of revenue also includes third-party costs associated with delivering and supporting our advertising products and credit card transaction fees related to processing customer transactions.

We expect cost of revenue will increase on an absolute dollar basis as neighbor activity on our platform increases. While we expect to realize scale benefits over time, our cost of revenue as a percentage of revenue may vary from period-to-period and is expected to increase modestly over the near and medium term as we invest in new products and features to further increase platform engagement.

Operating Expenses

Research and Development

Research and development expenses consist primarily of personnel-related costs, including salaries, benefits, and stock-based compensation for our employees engaged in research and development, as well as costs for consultants, contractors and third-party software. In addition, allocated overhead costs, such as facilities, information technology, and depreciation are included in research and development expenses.

We expect research and development expenses will increase on an absolute dollar basis due to investments that we are making in our platform. We expect that research and development expenses as a percentage of revenue will vary from period-to-period over the short term and decrease over the long term.

Sales and Marketing

Sales and marketing expenses consist of personnel-related and other costs which include salaries, commissions, benefits, and stock-based compensation for employees engaged in sales and marketing activities as well as other costs including third-party consulting, public relations, allocated overhead costs, and amortization of acquired intangible assets. Sales and marketing expenses also include brand and performance marketing for both user and small and mid-sized customer acquisition, and neighbor services, which includes personnel-related costs for our neighbor support team, our outsourced neighbor support function, and verification costs.

Performance marketing costs related to user acquisition largely consist of the distribution of mailed invitations and, to a lesser extent, digital advertising. Performance marketing costs related to small and mid-sized customer acquisition largely consists of digital advertising and, to a lesser extent, direct mail campaigns. Fluctuations in our performance marketing expenses are driven by a variety of factors, including but not limited to: our target geographies, whether we are acquiring users or businesses, assessment of return on investment of marketing spend, strategic priorities, and seasonal factors.

We expect sales and marketing expenses will increase on an absolute dollar basis due to continued investment in sales activities, increased investment in marketing to acquire users, small and mid-sized customers, and further investment in international expansion. We expect sales and marketing expenses as a percentage of revenue will vary from period-to-period over the short term and decrease over the long term.

228

General and Administrative

General and administrative expenses consist primarily of personnel-related costs, including salaries, benefits, and stock-based compensation for certain executives, finance, legal, information technology, human resources, and other administrative employees. In addition, general and administrative expenses include fees and costs for professional services, including consulting, third-party legal and accounting services, and allocated overhead costs.

We expect general and administrative expenses will increase on an absolute dollar basis for the foreseeable future to support our growth as well as due to additional costs associated with legal, accounting, compliance, investor relations, and other costs as we become a public company. We expect general and administrative expenses as a percentage of revenue will vary from period-to-period over the short term and decrease over the long term.

Interest Income

Interest income consists of interest earned on our cash, cash equivalents, and marketable securities.

Other Income (Expense), Net

Other income (expense), net consists primarily of unrealized gains and losses from the re-measurement of monetary assets and liabilities denominated in non-functional currencies, and foreign currency transaction gains and losses.

Provision for Income Taxes

The provision for income taxes consists primarily of income taxes related to foreign and state jurisdictions in which we conduct business. We maintain a full valuation allowance on our U.S. federal and state deferred tax assets as we have concluded that it is more likely than not that the deferred tax assets will not be realized.

Quarterly Trends

Revenue

Advertising spending is traditionally seasonally strong in the fourth quarter of each year and weakest in the first quarter of each year. This seasonality in advertising spending affects our quarterly results. For the periods presented, we experienced growth in quarterly revenue for each quarter of the year, and then a decline from the fourth quarter of the year to the following first quarter. For instance, our revenue in the fourth quarter of both 2019 and 2020 increased 26% as compared to the third quarter of both 2019 and 2020, while revenue in the first quarter of 2020 decreased 7% as compared to the fourth quarter of 2019 and advertising revenue for the first quarter of 2021 decreased 14% compared to the fourth quarter of 2020. The growth in our business may have partially masked these seasonal trends to date and the seasonal impacts may be more pronounced in the future.

Cost of revenue

Cost of revenue generally increased sequentially in each of the quarters presented primarily as a result of higher third-party hosting costs driven by user growth and engagement.

Research and development

Research and development expenses generally increased sequentially in each of the quarters presented primarily as a result of increased personnel-related costs as we continued to invest in innovation of our platform.

Sales and marketing

Sales and marketing expenses increased sequentially in each of the quarters presented, with the exception of the fourth quarter in 2019 and the second quarter of 2020. These increases were primarily as a result of increased personnel-related costs and higher brand and performance marketing spend. In the fourth quarter of 2019 and the second quarter of 2020, we reduced performance marketing spend for user acquisition. Further reduction in

236

performance marketing spend for user acquisition in the third quarter of 2020 was offset by increased spend for small and mid-sized customer acquisition and sales personnel costs.

General and administrative

General and administrative expenses increased sequentially in each of the quarters presented primarily as a result of an increase in personnel-related costs as we continued to invest in general and administrative functions.

Provision for income taxes

On a quarterly basis, provision for income taxes has fluctuated primarily due to foreign taxes.

Liquidity and Capital Resources

Since inception, we have generated negative cash flows from operations and have primarily financed our operations from net proceeds received from the sale of equity securities and payments received from our customers. As of June 30, 2021, we had raised an aggregate of $470.9 million, net of issuance costs, through the sales of redeemable convertible preferred stock and issuance of restricted stock. We currently have no debt outstanding.

We have generated losses from our operations, as reflected in our accumulated deficit of $431.7 million as of June 30, 2021. We incurred operating losses and cash outflows from operations by supporting the growth of our business. We expect these losses and operating cash outflows to continue for the foreseeable future. We also expect to incur significant research and development, sales and marketing, and general and administrative expenses over the next several years in connection with the continued development and expansion of our business.

As of June 30, 2021, we had $113.6 million in cash, cash equivalents, and marketable securities. We believe that our existing cash, cash equivalents, and marketable securities will be sufficient to meet our working capital and capital expenditure needs for at least the next 12 months.

Our future capital requirements will depend on many factors, including the rate of our revenue growth, the timing and extent of spending on research and development efforts and other business initiatives, the expansion of sales and marketing activities, the introduction of new and enhanced product offerings and features, and the continuing market adoption of our platform. We may in the future enter into arrangements to acquire or invest in complementary companies, products or technologies. We may be required to seek additional equity or debt financing. In the event that additional financing is required from outside sources, we may not be able to secure

237

timely additional financing on favorable terms, if at all. If we are unable to raise additional capital or generate cash flows necessary to expand our operations and invest in new technologies, it could reduce our ability to compete successfully and harm our business, results of operations, and financial condition.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements and did not have any such arrangements during the periods presented.

Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risk in the ordinary course of our business. Market risk represents the risk of loss that may impact our financial condition due to adverse changes in financial market prices and rates. Our market risk exposure is primarily the result of fluctuations in interest rates and foreign currency exchange rates.

Interest Rate Risk

As of June 30, 2021, we had cash and cash equivalents of $79.6 million and marketable securities of $34.0 million. Our cash and cash equivalents consist of cash in bank accounts, demand deposits and money market funds. The primary objectives of our investment activities are to preserve principal and provide liquidity without significantly increasing risk. We do not enter into investments for trading or speculative purposes. Due to the relatively short-term nature of our investment portfolio, a hypothetical 100 basis point change in interest rates would not have a material effect on the fair value of our portfolio for the periods presented.

Foreign Currency Risk

The functional currencies of our foreign subsidiaries are denominated in the respective local currencies as of January 1, 2020. Prior to January 1, 2020 the functional currency of our foreign subsidiaries was U.S. Dollars. Our sales are typically denominated in the local currency of the country in which the sale was made. The majority of our revenue is denominated in U.S. Dollars. As such, our revenue is not currently exposed to significant foreign currency risk. Our operating expenses are generally denominated in the currency of the countries in which the operations are located, and are subject to fluctuations due to changes in foreign currency exchange rates, particularly the British Pound, the Euro, Canadian Dollar and the Australian Dollar. Our consolidated results of operations and cash flows are, therefore, subject to fluctuations due to changes in foreign currency exchange rates and may be adversely affected in the future due to changes in foreign exchange rates. During the six months ended June 30, 2021 and 2020, and for the years ended December 31, 2020 and 2019, we do not believe a 10% change in the relative value of the U.S. Dollar would have materially affected our consolidated financial statements. To date, we have not had a formal hedging program with respect to foreign currency, but we may do so in the future if our exposure to foreign currency should become more significant.

Critical Accounting Policies and Estimates

We prepare our consolidated financial statements in accordance with GAAP. Preparing consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosures. We evaluate our estimates and assumptions on an ongoing basis. Our estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Our actual results could differ from these estimates.

The critical accounting policies requiring estimates, assumptions, and judgments that we believe have the most significant impact on our consolidated financial statements are described below.

Revenue Recognition

We generate a majority of our revenue from the delivery of advertising services.

We determine revenue recognition through the following steps:

1)Identification of the contract, or contracts, with a customer

2)Identification of the performance obligations in the contract

3)Determination of the transaction price

240

4)Allocation of the transaction price to the performance obligations in the contract

5)Recognition of revenue when, or as, we satisfy a performance obligation

We recognize advertising revenue after satisfying our contractual performance obligation, which, for the majority of our advertising arrangements, is when an advertising impression is displayed to users. None of our arrangements contain minimum impression guarantees. We typically bill advertisers on a monthly basis and our payment terms vary by customer type and location. We have other advertising arrangements for the sale of local sponsorship and local deals which are typically fixed-fee arrangements and revenue is recognized on a straight-line basis over the non-cancellable contractual term of the agreement, generally beginning on the date our service is made available to the customer.

Deferred Revenue

In certain advertising arrangements we require payment upfront from our customers. We record deferred revenue when we collect cash from customers in advance of revenue recognition.

Leases

At the inception of our contracts we determine if the contract is or contains a lease. A contract is or contains a lease if it conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Operating leases consist of real estate leases and are included in operating lease right-of-use assets and operating lease liabilities on our consolidated balance sheets at commencement date based on the present value of remaining fixed lease payments.

When the discount rate implicit in the lease cannot be readily determined, we use the applicable incremental borrowing rate at lease commencement in order to discount lease payments to present value for purposes of performing lease classification tests and measuring the lease liability. The incremental borrowing rate is a hypothetical rate based on the rate of interest we would have to pay to borrow on a collateralized basis over a similar term and amount equal to the lease payments in a similar economic environment.

Stock-based compensation

Stock-based compensation expense for stock-based awards is measured based on the grant date fair value of the awards and recognized in the consolidated statements of operations on a straight-line basis over the requisite service period of the awards. The grant date fair value of stock options granted is estimated using the Black-Scholes option pricing model. Forfeitures are accounted for as they occur. Historically, our stock option awards and restricted stock permitted early exercise. The unvested portion of shares exercised is recorded as a liability on our consolidated balance sheets and reclassified into stockholders' deficit as vesting occurs.

The Black-Scholes option-pricing model requires the use of highly subjective assumptions. These assumptions are estimated as follows:

•Fair Value of Common Stock-See 'Common Stock Valuations' below;

•Expected Volatility-Expected volatility is a measure of the amount by which the stock price is expected to fluctuate. Since we do not have sufficient trading history of our common stock, we estimate the expected volatility of our stock options at their grant date by taking the weighted average historical volatility of a group of comparable publicly traded companies over a period equal to the expected term of the options;

•Expected Term-We determine the expected term based on the average period the stock options are expected to remain outstanding using the simplified method, calculated as the midpoint of the stock options' vesting term and contractual expiration period, as we do not have sufficient historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior;

241

•Risk Free Interest Rate-We use the U.S. Treasury yield for our risk-free interest rate that corresponds with the expected term; and

•Dividend Yield-We utilize a dividend yield of zero, as we do not currently issue dividends and do not expect to in the future.

Common Stock Valuations

Prior to the Business Combination, given the absence of a public trading market for our common stock and in accordance with the American Institute of Certified Public Accountants Practice Aid, Valuation of Privately-Held Company Equity Securities Issued as Compensation, our board of directors determined the best estimate of the fair value of our common stock exercising reasonable judgment and considering numerous objective and subjective factors. These factors included:

•contemporaneous third-party valuations of our common stock;

•the prices at which we or other holders sold our common and redeemable convertible preferred stock to third-party investors in arms-length transactions;

•the rights, preferences, and privileges of our redeemable convertible preferred stock relative to those of our common stock;

•our financial condition, results of operations, and capital resources;

•our current business conditions and projections;

•the operational and financial performance of comparable publicly traded companies;

•the lack of marketability of our common stock;

•the likelihood of achieving a liquidity event, such as an initial public offering, a merger, or acquisition of our company given prevailing market conditions;

•the history and nature of our business, industry trends, and competitive environment; and

•general economic outlook including economic growth, inflation, unemployment, interest rate environment, and global economic trends.

In determining the fair value of our common stock, we first determine the enterprise value of our business, and then allocate the value among the various classes of our equity securities to derive a per share value of our common stock.

The enterprise value of our business was primarily estimated by reference to the closest round of equity financing preceding the date of the valuation. In a few cases, we also utilized the income and market approaches. The income approach estimates the value of our business based on the future cash flows we expect to generate discounted to their present value using an appropriate discount rate to reflect the risk of achieving the expected cash flows. The market approach estimates the value of our business by applying valuation multiples derived from the observed valuation multiples of comparable public companies to our expected financial results.

In allocating the enterprise value of our business among the various classes of stock prior to March 2021, we used the option pricing method, or OPM, which models each class of stock as a call option with a unique claim on our assets. We used a combination of probability weighted OPM and probability weighted expected return method, or PWERM, to allocate the enterprise value of our business among the various classes of stock since March 31, 2021. PWERM approach involves the estimation of forward-looking analysis of the possible future outcomes of the enterprise. This method is particularly useful when discrete future outcomes can be predicted at a relatively high confidence level with a probability distribution. Discrete future outcomes considered under the PWERM include a SPAC merger and an initial public offering, or IPO, of our common stock. Determining the fair value of the

242

enterprise using the PWERM requires us to develop assumptions and estimates for both the probability and timing of both SPAC and IPO liquidity events, as well as the values we expect those outcomes could yield.

After the allocation to the various classes of stock, a discount for lack of marketability, or DLOM, is applied to arrive at a fair value of the common stock. A DLOM accounts for the lack of marketability of a stock that is not traded on public exchanges. In making the final determination of common stock value, consideration is also given to the recent sales of common stock. In addition, we also considered any secondary transactions involving our capital stock and evaluated the nature of these transactions, including the average selling prices.

Application of these approaches involves the use of estimates, judgments, and assumptions that are highly complex and subjective. Changes in any or all of these estimates and assumptions or the relationships between those assumptions impact our valuations as of each valuation date and may have a material impact on the valuation of our common stock.

Following the Business Combination, it will not be necessary to determine the fair value of our common stock as the shares will be traded in a public market.

Income Taxes

We are subject to income taxes in the United States and numerous foreign jurisdictions. Significant judgment is required in determining our uncertain tax positions. We recognize a tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position.

We account for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the consolidated financial statements or in our tax returns. Deferred income taxes are recognized for differences between financial reporting and tax bases of assets and liabilities at the enacted statutory tax rates in effect for the years in which the temporary differences are expected to reverse. We make an assessment of the likelihood that the resulting deferred tax assets will be realized. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized.

JOBS Act Accounting Election

Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can choose not to take advantage of the extended transition period and comply with the requirements that apply to non-emerging growth companies, and any such election to not take advantage of the extended transition period is irrevocable. KVSB is an 'emerging growth company' as defined in Section 2(A) of the Securities Act of 1933, as amended, and has elected to take advantage of the benefits of this extended transition period.

New Nextdoor expects to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public business entities and non-public business entities until the earlier of the date New Nextdoor (a) is no longer an emerging growth company or (b) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. This may make it difficult or impossible to compare New Nextdoor's financial results with the financial results of another public company that is either not an emerging growth company or is an emerging growth company that has chosen not to take advantage of the extended transition period exemptions because of the potential differences in accounting standards used. See Note 2 of the accompanying audited consolidated financial statements and unaudited condensed consolidated financial statements of Nextdoor included elsewhere in this proxy statement/prospectus for the recent accounting pronouncements adopted and the recent accounting pronouncements not yet adopted for the years ended December 31, 2020 and 2019 and for the six months ended June 30, 2021.

In addition, New Nextdoor intends to rely on the other exemptions and reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, if, as an emerging growth company, New

243

Nextdoor intends to rely on such exemptions, New Nextdoor is not required to, among other things: (a) provide an auditor's attestation report on New Nextdoor's system of internal control over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act; (b) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act; and (c) disclose certain executive compensation-related items such as the correlation between executive compensation and performance and comparisons of the Chief Executive Officer's compensation to median employee compensation.

New Nextdoor will remain an emerging growth company under the JOBS Act until the earliest of (a) the last day of New Nextdoor's first fiscal year following the fifth anniversary of KVSB's initial public offering, (b) the last date of New Nextdoor's fiscal year in which New Nextdoor has total annual gross revenue of at least $1.1 billion, (c) the date on which New Nextdoor is deemed to be a 'large accelerated filer' under the rules of the SEC with at least $700.0 million of outstanding securities held by non-affiliates or (d) the date on which New Nextdoor has issued more than $1.0 billion in non-convertible debt securities during the previous three years.

Election of executive officers

New Nextdoor's executive officers will be appointed by, and serve at the discretion of, the New Nextdoor Board.

Family relationships

There are no family relationships among any of New Nextdoor's expected executive officers or directors.

Board composition

New Nextdoor's business and affairs will be organized under the direction of the New Nextdoor Board. We anticipate that the New Nextdoor Board will consist of ten members upon the consummation of the Business Combination. Sarah Friar will serve as Chairperson of the New Nextdoor Board. Upon consummation of the Business Combination, the New Nextdoor Board will appoint Christopher Varelas as lead independent director. The primary responsibility of the New Nextdoor Board will be to provide oversight, strategic guidance, counseling and direction to New Nextdoor's management. The New Nextdoor Board will meet on a regular basis and additionally as required.

Classified board of directors

Effective upon the consummation of the Business Combination, the New Nextdoor Board will consist of ten members. In accordance with the terms of the Proposed Certificate of Incorporation, which will be effective upon the consummation of the Business Combination, the New Nextdoor Board will be divided into three classes of directors that will serve staggered three-year terms. At each annual meeting of stockholders, a class of directors will be elected for a three-year term to succeed the same class whose term is then expiring. As a result, only one class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms. The New Nextdoor Board will be divided among the three classes as follows:

•the Class I directors, which we anticipate will be J. William Gurley, Jason Pressman and Nirav Tolia, whose terms will expire at the first annual meeting of stockholders to be held after the consummation of the Business Combination;

•the Class II directors, which we anticipate will be Sarah Friar, Leslie Kilgore and David Sze, whose terms will expire at the second annual meeting of stockholders to be held after the consummation of the Business Combination; and

•the Class III directors, which we anticipate will be John Hope Bryant, Mary Meeker, Chris Varelas and Andrea Wishom, whose terms will expire at the third annual meeting of stockholders to be held after the consummation of the Business Combination.

Each director's term will continue until the election and qualification of his or her successor, or his or her earlier death, resignation, or removal. The Proposed Certificate of Incorporation and Proposed Bylaws, which, in each case, will be effective upon the consummation of the Business Combination will authorize only the New Nextdoor Board to fill vacancies on the New Nextdoor Board. In addition, the number of directors constituting the New Nextdoor Board may be set only by resolution adopted by a majority vote of the entire New Nextdoor Board. Any increase or decrease in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. This classification of the New Nextdoor Board may have the effect of delaying or preventing changes in control of New Nextdoor.

248

Director independence

Upon the consummation of the Business Combination, the New Nextdoor Board is expected to determine that each of the directors except for Ms. Friar and Mr. Tolia on the New Nextdoor Board will qualify as independent directors under the rules of ('Exchange'), and SEC rules and regulations. Ms. Friar was determined to not be independent because she is expected to serve as Chief Executive Officer and President of New Nextdoor and Mr. Tolia was determined not be independent because he served as Nextdoor's Chief Executive Officer in the last three years and received compensation in connection with such service. Under the rules of the Exchange, independent directors must comprise a majority of a listed company's board of directors. In addition, the rules of the Exchange require that, subject to specified exceptions, each member of a listed company's audit, compensation, and nominating and governance committees be independent. Under the rules of Exchange, a director will only qualify as an 'independent director' if, in the opinion of that company's board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In making these determinations, the New Nextdoor Board will review and discuss information provided by the directors and New Nextdoor with regard to each director's business and personal activities and relationships as they may relate to Nextdoor and its management, including the beneficial ownership of capital stock by each non-employee director and the transactions involving them as described in the section entitled 'Certain Relationships and Related Party Transactions.'

Audit and risk committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act. In order to be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors or any other board committee: (i) accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries; or (ii) be an affiliated person of the listed company or any of its subsidiaries. New Nextdoor intends to satisfy the audit committee independence requirements of Rule 10A-3 as of the consummation of the Business Combination. Additionally, compensation committee members must not have a relationship with New Nextdoor that is material to the director's ability to be independent from management in connection with the duties of a compensation committee member.

Committees of the Board

Effective upon the consummation of the Business Combination, the New Nextdoor Board will have three standing committees - an audit and risk committee, a compensation committee, and a nominating and governance committee. Following the consummation of the Business Combination, copies of the charters for each committee will be available on New Nextdoor's website. The reference to New Nextdoor's website address in this filing does not include or incorporate by reference the information on that website into this filing.

Audit and risk committee

New Nextdoor's audit and risk committee ('audit and risk committee') will consist of J. William Gurley, Jason Pressman and Chris Varelas, with J. William Gurley serving as the chair.

William Gurley qualifies as an audit committee financial expert within the meaning of the SEC regulations and meets the financial sophistication requirements of the Exchange listing rules. In making this determination, the New Nextdoor Board will consider J. William Gurley's formal education and previous experience in financial roles. Both New Nextdoor's independent registered public accounting firm and management periodically will meet privately with New Nextdoor's audit and risk committee.

The functions of this committee are expected to include, among other things:

•selecting a firm to serve as our independent registered public accounting firm to audit our financial statements;

•reviewing legal, financial, technology, and enterprise risk exposures and the steps management has taken to monitor and control such exposures.

The composition and function of the audit and risk committee will comply with all applicable requirements of the Sarbanes-Oxley Act and all applicable SEC rules and regulations. New Nextdoor will comply with future requirements to the extent they become applicable to New Nextdoor.

Compensation committee

New Nextdoor's compensation committee ('compensation committee') will consist of Leslie Kilgore, Mary Meeker, David Sze and Andrea Wishom, with Leslie Kilgore serving as the chair.

•administering and interpreting our cash and equity incentive compensation plans;

•reviewing and approving, or making recommendations to the Board with respect to, cash and equity incentive compensation; and

•establishing New Nextdoor's overall compensation philosophy.

The composition and function of the compensation committee will comply with all applicable requirements of the Sarbanes-Oxley Act and all applicable SEC rules and regulations. New Nextdoor will comply with future requirements to the extent they become applicable to New Nextdoor.

Nominating and governance committee

New Nextdoor's nominating and governance committee ('nominating and governance committee') will consist of John Hope Bryant and Chris Varelas, with Chris Varelas serving as the chair. The New Nextdoor Board is

The functions of the nominating and governance committee are expected to include:

Before the Business Combination, Nextdoor did not have a formal policy to provide any cash or equity compensation to its non-employee directors for their service on the board of directors or committees of the board of directors. Following the Business Combination, the Board expects to approve a non-employee director compensation policy, which will be designed to align compensation with New Nextdoor's business objectives and the creation of stockholder value, while enabling New Nextdoor to attract, retain, incentivize and reward directors who contribute to the long-term success of the company. The terms of such non-employee director compensation policy will be determined following the Closing.

Nextdoor is party to an offer letter agreement with Mr. Orta, dated May 31, 2018 (the 'Orta Offer Letter'), which provides for 'at-will' employment without a set term and entitled Mr. Orta to a signing bonus of $50,000, and an annual base salary of $250,000. As of December 31, 2020, Mr. Orta's base salary was $350,000.

For purposes of the Orta Offer Letter:

259

Severance Agreements

It is expected that New Nextdoor will enter into individual Severance Agreements with each of our executive officers. Under each Severance Agreement, if the applicable executive officer is terminated by us without cause or who resigns for good reason outside of a change in control (each such term as defined in each Severance Agreement), he or she will receive, in exchange for a customary release of claims: (i) a severance payment of six months' base salary in a cash lump sum and (ii) payment of premiums for continued medical benefits for up to six months following termination.

If the applicable executive officer's employment is terminated by us without cause or by an executive for good reason within the three months preceding a change in control (but after a legally binding and definitive agreement for a potential change of control has been executed) or within the twelve months following a change in control, the Severance Agreements provide the following benefits in exchange for a customary release of claims: (i) a severance payment of twelve months' base salary and then-current target bonus opportunity at 100% achievement of target (in each case, at the rates in effect immediately prior to the actions that resulted in the termination) paid in a cash lump sum, (ii) full acceleration of time-vesting equity awards and accelerated vesting of performance vesting equity awards at the greater of (x) actual achievement through the date of termination or (y) target level (unless an individual equity award agreement provides otherwise), and (iii) payment of premiums for continued medical benefits for up to twelve months following termination.

Each Severance Agreement will remain in effect until the earlier of the third anniversary of the effective date of such Severance Agreement or the date the applicable executive officer's employment with us terminates for a reason other than a Qualifying Termination or CIC Qualifying Termination (each as defined in the Severance Agreements); provided however, if a definitive agreement relating to a change in control has been signed by us on or before the expiration date, then the Severance Agreement shall remain in effect until (i) the termination of the executive officer's employment other than in a situation described above and (ii) the date that we have met all our obligations under the Severance Agreement following the termination of the executive officer's employment due to a situation described above (each capitalized term as defined in each Severance Agreement).

The benefits under the Severance Agreements will supersede all other cash severance and vesting acceleration arrangements under any agreement governing equity awards, severance and salary continuation arrangements, programs and plans which were previously offered by us to the applicable executive officers, including under any employment agreement or offer letter.

BENEFICIAL OWNERSHIP OF SECURITIES

The following table sets forth information regarding (i) the beneficial ownership of KVSB common stock as of June 30, 2021 and (ii) the expected beneficial ownership of shares of New Nextdoor common stock immediately following consummation of the Business Combination (assuming a 'no redemption' scenario and assuming a 'redemption' scenario as described below) by:

•each person who is known to be the beneficial owner of more than 5% of KVSB common stock and is expected to be the beneficial owner of more than 5% of shares of New Nextdoor common stock post-Business Combination;

•each of KVSB's current executive officers and directors;

•each person who will become an executive officer or director of New Nextdoor post-Business Combination; and

•all executive officers and directors of KVSB as a group pre-Business Combination, and all executive officers and directors of New Nextdoor post-Business Combination.

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security, including options and warrants that are currently exercisable or exercisable within 60 days.

The beneficial ownership of KVSB common stock pre-Business Combination is based on 52,767,100 shares of KVSB common stock issued and outstanding as of June 30, 2021, which includes an aggregate of 5,000,000 shares of KVSB Class B common stock outstanding as of such date.

The expected beneficial ownership of shares of New Nextdoor common stock post-Business Combination assumes two scenarios:

(i)a 'no redemption' scenario where (i) no public stockholders exercise their redemption rights in connection with the Business Combination or our extension proposal and (ii) New Nextdoor has 382,708,582 shares of New Nextdoor common stock following the Business Combination (excluding equity awards issued to Nextdoor stockholders and the shares reserved for issuance pursuant to the Pixel Labs Merger Agreement); and

(ii)a 'redemption' scenario where (i) 24,932,638 of KVSB's outstanding public shares are redeemed in connection with the Business Combination for an aggregate payment of $249.3 million, which is derived from the number of shares that could be redeemed in connection with the Transactions at an assumed redemption price of $10.00 per share based on funds held in the trust account as of June 30, 2021 and still satisfy the Minimum Cash Condition required to consummate the Transactions of at least $400.0 million after giving effect to the (a) proceeds from the PIPE Investment, (b) payment of the estimated transaction costs incurred in connection with the Transactions of $47.0 million, including deferred underwriting commissions and unpaid offering costs from KVSB's initial public offering, and (c) proceeds of $10.0 million from the Sponsor Forward Purchase Agreement and (ii) New Nextdoor has 358,775,944 shares of New Nextdoor common stock following the Business Combination (excluding equity awards issued to Nextdoor stockholders and the shares reserved for issuance pursuant to the Pixel Labs Merger Agreement).

Based on the foregoing assumptions, and including the 27,000,000 shares of New Nextdoor Class A common stock issued in connection with the PIPE Investment, we estimate that there would be 382,708,582 shares of New Nextdoor common stock issued and outstanding immediately following the consummation of the Business Combination in the 'no redemption' scenario, and 358,775,944 shares of New Nextdoor common stock issued and outstanding

261

immediately following the consummation of the Business Combination in the ' redemption' scenario. If the actual facts are different from the foregoing assumptions, ownership figures in the combined company and the columns under Post-Business Combination in the table that follows will be different.

Unless otherwise indicated, KVSB believes that all persons named in the table below have sole voting and investment power with respect to the voting securities beneficially owned by them.

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

Khosla Ventures Acquisition Co. II

Founder Shares

On January 29, 2021, the Sponsor acquired 10,000,000 founder shares for an aggregate purchase price of $25,000, consisting of 5,000,000 Class B founder shares and 5,000,000 Class K founder shares. Prior to the initial investment in KVSB of $25,000 by the sponsor, KVSB had no assets, tangible or intangible. The per share purchase price of the founder shares was determined by dividing the amount of cash contributed to KVSB by the aggregate number of founder shares issued. On March 10, 2021, the Sponsor entered into a security assignment agreement with three of KVSB's independent directors and assigned 120,000 shares of Class B common stock at an aggregate price of $300.

KVSB Class B Founder Shares

All KVSB Class B founder shares will automatically convert into an aggregate of 7,347,249 shares of KVSB Class A common stock following the completion of our initial business combination. Prior to our initial business combination, only holders of shares of our Class B common stock were entitled to vote on the appointment of directors.

KVSB Class K Founder Shares

All KVSB Class K founder shares are being converted into an aggregate of 3,061,354 shares of New Nextdoor Class B common stock. Prior to such reclassification, the Class K founder shares would only have converted into shares of Class A common stock after the initial business combination to the extent certain triggering events occurred prior to the 10th anniversary of the initial business combination, including three equal triggering events based on our stock trading at $20.00, $25.00 and $30.00 per share following the first anniversary of the closing of our initial business combination and also upon specified strategic transactions. Prior to our initial business combination, only holders of shares of our Class B common stock were entitled to vote on the appointment of directors. KVSB performed an assessment in accordance with ASC 480 - Distinguishing Liabilities from Equities and ASC 815 - Derivatives and Hedging to conclude whether the embedded features of Class K common stock constitute a liability and a derivative such that it will be fair valued separately from the KVSB's common stock. KVSB concludes that Class K common stock should be equity-classified and its embedded features should not be bifurcated.

Promissory Note - Related Parties

On February 8, 2021, KVSB issued a promissory note (the 'Promissory Note') to the Sponsor and an affiliate of the Sponsor, pursuant to which KVSB could borrow up to an aggregate principal amount of $300,000. The Promissory Note was non-interest bearing and payable on the earlier of (i) December 31, 2021 and (ii) the completion of the IPO. The outstanding balance under the Promissory Note was repaid upon consummation of the IPO. The outstanding balance under the Promissory Note at June 30, 2021 was $5,300.

Related Party Transactions

In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of KVSB's officers and directors may, but are not obligated to, loan KVSB funds as may be required ('Working Capital Loans'). If KVSB completes a Business Combination, KVSB would repay the Working Capital Loans out of the proceeds of the Trust Account released to KVSB. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, KVSB may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. To date, KVSB had no borrowings under the Working Capital Loans.

266

Private Placement Shares

Concurrently with the closing of the IPO and the partial exercise of the underwriters' over-allotment option, the Sponsor purchased 1,132,688 private placement shares from KVSB at a price of $10.00 per share in private placements for an aggregate purchase price of $11,326,880. The private placement shares are identical to the public shares, subject to certain limited exceptions. Pursuant to the sponsor support agreement, the private placement shares will be exchanged at a ratio of 1:1 into shares of New Nextdoor Class B common stock.

The initial stockholders agreed, subject to limited exceptions, not to transfer, assign or sell any of their private placement shares until 30 days after the completion of the initial business combination.

Forward Purchase Agreement

KVSB entered into a forward purchase agreement pursuant to which the Sponsor agreed to purchase an aggregate of up to 1,000,000 forward-purchase shares for $10.00 per share, or an aggregate maximum amount of $10,000,000, in a private placement that would close simultaneously with the closing of the initial business combination. The proceeds from the sale of these forward-purchase shares, together with the amounts available to KVSB from the trust account (after giving effect to any redemptions of public shares) and PIPE Investment, will be used to satisfy the cash requirements of the business combination, including funding the purchase price and paying expenses and retaining specified amounts to be used by the post-business combination company for working capital or other purposes, including the Minimum Cash Condition. To the extent that the amounts available from the trust account and other financing are sufficient for such cash requirements, the Khosla Entities may purchase less than 1,000,000 forward-purchase shares. The forward-purchase shares would be shares of KVSB Class A common stock. KVSB performed an assessment in accordance with ASC 480 - Distinguishing Liabilities from Equities and ASC 815 - Derivatives and Hedging to conclude whether the forward-purchase shares constitute a liability and a derivative such that it will be fair valued separately from KVSB's common stock. KVSB concludes that the forward-purchase shares should be equity-classified and its embedded features should not be bifurcated.

269

DESCRIPTION OF NEW NEXTDOOR SECURITIES

General

The following summary of certain provisions of New Nextdoor securities does not purport to be complete and is subject to the Proposed Certificate of Incorporation, the Proposed Bylaws and the provisions of applicable law. Copies of the Proposed Certificate of Incorporation and the Proposed Bylaws are attached to this proxy statement/prospectus as Annex C and Annex D, respectively.

Upon the completion of the Business Combination, New Nextdoor's authorized common stock will consist of 2,500,000,000 shares of New Nextdoor Class A common stock, $0.0001 par value per share, 500,000,000 shares of New Nextdoor Class B common stock, $0.0001 par value per share, and 50,000,000 shares of undesignated preferred stock, $0.0001 par value per share. New Nextdoor expects to have approximately 68,634,412 shares of New Nextdoor Class A common stock and 314,074,170 shares of New Nextdoor Class B common stock outstanding immediately after the consummation of the Business Combination, assuming no public stockholders exercise their redemption rights in connection with the Business Combination.

Class A Common Stock and Class B Common Stock

Dividend Rights

Subject to preferences that may apply to any shares of convertible preferred stock outstanding at the time, the holders of shares of New Nextdoor common stock are entitled to receive dividends out of funds legally available if New Nextdoor board of directors, in its discretion, determines to issue dividends and then only at the times and in the amounts that New Nextdoor board of directors may determine.

Voting Rights

Following the Business Combination, holders of shares of New Nextdoor Class A common stock will be entitled to one vote for each share of Class A common stock held on all matters submitted to a vote of stockholders and holders of New Nextdoor Class B common stock will be entitled to 10 votes for each share of New Nextdoor Class B common stock held on all matters submitted to a vote of stockholders. Following the Business Combination (assuming that no public stockholders exercise their redemption rights in connection with the Business Combination), the holders of New Nextdoor outstanding Class B common stock will hold approximately 97.9% of the voting power of New Nextdoor outstanding common stock, with New Nextdoor directors, executive officers, and beneficial owners of 5% or greater of New Nextdoor outstanding common stock and their respective affiliates holding 54.2% of the voting power in the aggregate. Holders of shares of New Nextdoor Class A common stock and Class B common stock vote together as a single class on all matters (including the election of directors) submitted to a vote of stockholders, unless, otherwise required by Delaware law or the Proposed Certificate of Incorporation. Delaware law could require either holders of New Nextdoor Class A common stock or Class B common stock to vote separately as a single class in the following circumstances:

•if New Nextdoor were to seek to amend the Proposed Certificate of Incorporation to increase or decrease the par value of a class of New Nextdoor common stock, then that class would be required to vote separately to approve the proposed amendment; and

•if New Nextdoor were to seek to amend the Proposed Certificate of Incorporation in a manner that alters or changes the powers, preferences, or special rights of a class of New Nextdoor common stock in a manner that affected its holders adversely, then that class would be required to vote separately to approve the proposed amendment.

New Nextdoor has not provided for cumulative voting for the election of directors in the Proposed Certificate of Incorporation that will become effective immediately prior to the completion of this offering. Accordingly, holders of a majority of the shares of New Nextdoor common stock will be able to elect all of the New Nextdoor directors.

270

No Preemptive or Similar Rights

New Nextdoor common stock is not entitled to preemptive rights, and is not subject to redemption or sinking fund provisions.

Right to Receive Liquidation Distributions

Upon New Nextdoor liquidation, dissolution or winding-up, the assets legally available for distribution to New Nextdoor stockholders would be distributable ratably among the holders of New Nextdoor common stock and any participating preferred stock outstanding at that time, subject to prior satisfaction of all outstanding debt and liabilities and the preferential rights of and the payment of liquidation preferences, if any, on any outstanding shares of preferred stock.

Conversion

Following the completion of this offering, each share of our Class B common stock will be convertible into one share of our Class A common stock automatically, without further action by New Nextdoor immediately prior to the close of business on the earlier of (i) ten (10) years from the date of the Closing and (ii) the date specified by an affirmative vote of the holders of Class B Common Stock representing not less than two-thirds (2/3) of the voting power of the outstanding shares of Class B Common Stock, voting separately as a single class.

Lock-up Period

Following the Business Combination, certain of the former holders of Nextdoor common stock, Nextdoor Options, Nextdoor Restricted Stock or other equity awards outstanding immediately prior to the effective time of the Business Combination have agreed not to sell, pledge, transfer or otherwise dispose of, or grant any option or purchase right with respect to, any shares of New Nextdoor Class A common stock or New Nextdoor Class B common stock issued to such holders pursuant to the Business Combination ('Lock-Up Shares'), or engage in any short sale, hedging transaction or other derivative security transaction involving the Lock-Up Shares, for a lock-up period commencing on the closing date of the Business Combination until 180 days following the closing of the Business Combination, subject to customary exceptions.

Preferred Stock

Following the Business Combination, New Nextdoor's board of directors will be authorized, subject to limitations prescribed by Delaware law, to issue up to 50,000,000 shares of preferred stock in one or more series, to establish from time to time the number of shares to be included in each series, and to fix the designation, powers, preferences, and rights of the shares of each series and any of its qualifications, limitations or restrictions, in each case without further vote or action by New Nextdoor's stockholders. New Nextdoor's board of directors can also increase or decrease the number of shares of any series of preferred stock, but not below the number of shares of that series then outstanding, without any further vote or action by New Nextdoor's stockholders. The number of authorized shares of New Nextdoor's preferred stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the voting stock, without a separate vote of the holders of the preferred stock, irrespective of the provisions of Section 242(b)(2) of the DGCL, unless a separate vote of the holders of one or more series is required pursuant to the terms of any applicable certificate of designation. New Nextdoor's board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of New Nextdoor's common stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring, or preventing a change in New Nextdoor's control and might adversely affect the market price of New Nextdoor's Class A common stock and the voting and other rights of the holders of New Nextdoor's Class A common stock and Class B common stock. New Nextdoor does not currently plan to issue any shares of preferred stock.

271

Anti-Takeover Provisions

The provisions of the DGCL, the Proposed Certificate of Incorporation, and the Proposed Bylaws following this offering could have the effect of delaying, deferring or discouraging another person from acquiring control of New Nextdoor. These provisions, which are summarized below, are expected to discourage certain types of coercive takeover practices and inadequate takeover bids and encourage persons seeking to acquire control of New Nextdoor to first negotiate with the New Nextdoor board of directors. New Nextdoor believes that the benefits of increased protection of New Nextdoor potential ability to negotiate with an unfriendly or unsolicited acquirer outweigh the disadvantages of discouraging a proposal to acquire New Nextdoor because negotiation of these proposals could result in an improvement of their terms.

Delaware Law

New Nextdoor is subject to the provisions of Section 203 of the DGCL regulating corporate takeovers. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a 'business combination' with an 'interested stockholder' for a three-year period following the time that this stockholder becomes an interested stockholder, unless the business combination is approved in a prescribed manner. Under Section 203, a business combination between a corporation and an interested stockholder is prohibited unless it satisfies one of the following conditions:

•before the stockholder became interested, the New Nextdoor board of directors approved either the business combination or the transaction, which resulted in the stockholder becoming an interested stockholder;

•upon consummation of the transaction, which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding, shares owned by persons who are directors and also officers, and employee stock plans in some instances, but not the outstanding voting stock owned by the interested stockholder; or

•at or after the time the stockholder became interested, the business combination was approved by the New Nextdoor board of directors and authorized at an annual or special meeting of the stockholders by the affirmative vote of at least two-thirds of the outstanding voting stock, which is not owned by the interested stockholder.

Section 203 defines a business combination to include:

•any merger or consolidation involving the corporation and the interested stockholder;

•any sale, transfer, lease, pledge, or other disposition involving the interested stockholder of 10% or more of the assets of the corporation;

•subject to exceptions, any transaction that results in the issuance of transfer by the corporation of any stock of the corporation to the interested stockholder;

•subject to exceptions, any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation beneficially owned by the interested stockholder; and

•the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges, or other financial benefits provided by or through the corporation.

In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by the entity or person.

272

Proposed Certificate of Incorporation and Restated Bylaw Provisions

The Proposed Certificate of Incorporation and the Proposed Bylaws will include a number of provisions that may have the effect of deterring hostile takeovers, or delaying or preventing changes in control of the New Nextdoor management team or changes in the New Nextdoor board of directors or New Nextdoor governance or policy, including the following:

•Dual Class Common Stock. As described above in the section entitled '- Class A Common Stock and Class B Common Stock-Voting Rights,' the Proposed Certificate of Incorporation will provide for a dual class common stock structure pursuant to which holders of New Nextdoor Class B common stock will have the ability to control the outcome of matters requiring stockholder approval, even if they own significantly less than a majority of the shares of New Nextdoor outstanding Class A and Class B common stock, including the election of directors and significant corporate transactions, such as a merger or other sale of New Nextdoor or its assets. New Nextdoor's investors, executives, and employees will have the ability to exercise significant influence over those matters.

•Board of Directors Vacancies. The Proposed Certificate of Incorporation and the Proposed Bylaws and will authorize generally only the New Nextdoor board of directors to fill vacant directorships resulting from any cause or created by the expansion of the New Nextdoor board of directors. In addition, the number of directors constituting the New Nextdoor board of directors may be set only by resolution adopted by a majority vote of the New Nextdoor entire board of directors. These provisions prevent a stockholder from increasing the size of the New Nextdoor board of directors and gaining control of the New Nextdoor board of directors by filling the resulting vacancies with its own nominees.

•Classified Board. The Proposed Certificate of Incorporation and the Proposed Bylaws will provide that the New Nextdoor board of directors is classified into three classes of directors. The existence of a classified board of directors could delay a successful tender offeror from obtaining majority control of the New Nextdoor board of directors, and the prospect of that delay might deter a potential offeror. For additional information, see the section entitled 'Management of New Nextdoor following the Business Combination-Executive officers and directors after the Business Combination-Classified Board of Directors.'

•Directors Removed Only for Cause. The Proposed Certificate of Incorporation will provide that stockholders may remove directors only for cause and only by the affirmative vote of the holders of at least two-thirds of the voting power of the then-outstanding common stock.

•Supermajority Requirements for Amendments of the Proposed Certificate of Incorporation and Proposed Bylaws. The Proposed Certificate of Incorporation will further provide that the affirmative vote of holders of at least two-thirds (2/3) of the voting power of all of the then outstanding shares of capital stock will be required to amend certain provisions of the Proposed Charter, including provisions relating to the classified board, the size of the New Nextdoor board of directors, removal of directors, special meetings, actions by written consent and designation of our preferred stock, provided that if two-thirds of the New Nextdoor board of directors has approved such amendment only the affirmative vote of a majority of the voting power of all of the then outstanding shares of capital stock shall be required to amend the Proposed Charter. The affirmative vote of holders of at least two-thirds (2/3) of the voting power of all of the then outstanding shares of common stock will be required to amend or repeal the Proposed Bylaws, although the Proposed Bylaws may be amended by a simple majority vote of the New Nextdoor board of directors. Additionally, in the case of any proposed adoption, amendment, or repeal of any provisions of the Proposed Bylaws that is approved by the New Nextdoor board of directors and submitted to the stockholders for adoption, if two-thirds of the New Nextdoor board of directors has approved such adoption, amendment, or repeal of any provisions of the Proposed Bylaws, then only the affirmative vote of a majority of the voting power of all of the then outstanding shares of common stock shall be required to adopt, amend, or repeal any provision of the Proposed Bylaws.

•Stockholder Action; Special Meetings of Stockholders. The Proposed Certificate of Incorporation will provide that New Nextdoor stockholders may not take action by written consent, but may only take action

273

at annual or special meetings of New Nextdoor stockholders. As a result, holders of New Nextdoor common stock would not be able to amend the Proposed Bylaws or remove directors without holding a meeting of New Nextdoor stockholders called in accordance with the Proposed Bylaws. The Proposed Certificate of Incorporation and the Proposed Bylaws will provide that special meetings of New Nextdoor stockholders may be called only by a majority of the New Nextdoor board of directors, the chairman of the New Nextdoor board of directors or the New Nextdoor chief executive officer, thus prohibiting a stockholder from calling a special meeting. These provisions might delay the ability of New Nextdoor stockholders to force consideration of a proposal or for stockholders to take any action, including the removal of directors.

•Advance Notice Requirements for Stockholder Proposals and Director Nominations. The Proposed Bylaws will provide advance notice procedures for stockholders seeking to bring business before the New Nextdoor annual meeting of stockholders or to nominate candidates for election as directors at the New Nextdoor annual meeting of stockholders. The Proposed Bylaws also will specify certain requirements regarding the form and content of a stockholder's notice. These provisions may preclude New Nextdoor stockholders from bringing matters before the New Nextdoor annual meeting of stockholders or from making nominations for directors at the New Nextdoor annual meeting of stockholders. New Nextdoor expects that these provisions might also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer's own slate of directors or otherwise attempting to obtain control of New Nextdoor.

•No Cumulative Voting. The DGCL provides that stockholders are not entitled to the right to cumulate votes in the election of directors unless a corporation's certificate of incorporation provides otherwise. The Proposed Certificate of Incorporation and Proposed Bylaws will not provide for cumulative voting.

•Issuance of Undesignated Preferred Stock. New Nextdoor anticipates that after the filing of the Proposed Certificate of Incorporation, the New Nextdoor board of directors will have the authority, without further action by the stockholders, to issue up to 50,000 shares of undesignated preferred stock with rights and preferences, including voting rights, designated from time to time by the New Nextdoor board of directors. The existence of authorized but unissued shares of preferred stock enables the New Nextdoor board of directors to render more difficult or to discourage an attempt to obtain control of New Nextdoor by means of a merger, tender offer, proxy contest or otherwise.

•Choice of Forum. In addition, the Proposed Certificate of Incorporation will provide that, to the fullest extent permitted by law, the Court of Chancery of the State of Delaware will be the exclusive forum for any derivative action or proceeding brought on New Nextdoor's behalf; any action asserting a breach of fiduciary duty; any action asserting a claim against New Nextdoor arising pursuant to the DGCL, the Proposed Certificate of Incorporation or the Proposed Bylaws; any action asserting a claim against New Nextdoor that is governed by the internal affairs doctrine; or any to interpret, apply, enforce, or determine the validity of the Proposed Certificate of Incorporation or Proposed Bylaws. The enforceability of similar choice of forum provisions in other companies' certificates of incorporation has been challenged in legal proceedings, and it is possible that a court could find these types of provisions to be inapplicable or unenforceable. The Proposed Certificate of Incorporation will also provide that the federal district courts of the United States will, to the fullest extent permitted by law, be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act, or the Federal Forum Provision. While there can be no assurance that federal or state courts will follow the holding of the Delaware Supreme Court which recently found that such provisions are facially valid under Delaware law or determine that the Federal Forum Provision should be enforced in a particular case, application of the Federal Forum Provision means that suits brought by New Nextdoor stockholders to enforce any duty or liability created by the Securities Act must be brought in federal court and cannot be brought in state court. Section 27 of the Exchange Act creates exclusive federal jurisdiction over all claims brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. In addition, the Federal Forum Provision applies, to the fullest extent permitted by law, to suits brought to enforce any duty or liability created by the Exchange Act. Accordingly, actions by New Nextdoor stockholders to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder must be brought in

274

federal court. New Nextdoor stockholders will not be deemed to have waived New Nextdoor compliance with the federal securities laws and the regulations promulgated thereunder. Any person or entity purchasing or otherwise acquiring or holding any interest in any of New Nextdoor securities shall be deemed to have notice of and consented to the New Nextdoor exclusive forum provisions, including the Federal Forum Provision. These provisions may limit a stockholder's ability to bring a claim in a judicial forum of their choosing for disputes with New Nextdoor or the New Nextdoor directors, officers, or other employees, which may discourage lawsuits against New Nextdoor and the New Nextdoor directors, officers, and other employees.

Transfer Agent and Registrar

Upon the completion of the Business Combination, the transfer agent and registrar for New Nextdoor Class A common stock and Class B common stock will be . The transfer agent's address is .

275

SECURITIES ACT RESTRICTIONS ON RESALE OF NEW NEXTDOOR SECURITIES

Pursuant to Rule 144 under the Securities Act ('Rule 144'), a person who has beneficially owned restricted New Nextdoor common stock for at least six months would be entitled to sell their securities provided that (i) such person is not deemed to have been an affiliate of New Nextdoor at the time of, or at any time during the three months preceding, a sale and (ii) New Nextdoor is subject to the Exchange Act periodic reporting requirements for at least three months before the sale and have filed all required reports under Section 13 or 15(d) of the Exchange Act during the 12 months (or such shorter period as New Nextdoor was required to file reports) preceding the sale.

Persons who have beneficially owned restricted New Nextdoor shares of common stock for at least six months but who are affiliates of New Nextdoor at the time of, or at any time during the three months preceding, a sale, would be subject to additional restrictions, by which such person would be entitled to sell within any three-month period only a number of securities that does not exceed the greater of:

•1% of the total number of New Nextdoor common stock then outstanding; or

•the average weekly reported trading volume of New Nextdoor's common stock during the four calendar weeks preceding the filing of a notice on Form 144 with respect to the sale.

Sales by affiliates of New Nextdoor under Rule 144 are also limited by manner of sale provisions and notice requirements and to the availability of current public information about New Nextdoor.

Restrictions on the Use of Rule 144 by Shell Companies or Former Shell Companies

Rule 144 is not available for the resale of securities initially issued by shell companies (other than business combination related shell companies) or issuers that have been at any time previously a shell company. However, Rule 144 also includes an important exception to this prohibition if the following conditions are met:

•the issuer of the securities that was formerly a shell company has ceased to be a shell company;

•the issuer of the securities is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act;

•the issuer of the securities has filed all Exchange Act reports and material required to be filed, as applicable, during the preceding 12 months (or such shorter period that the issuer was required to file such reports and materials), other than Form 8-K reports; and

•at least one year has elapsed from the time that the issuer filed current Form 10 type information with the SEC reflecting its status as an entity that is not a shell company.

As a result, the Sponsor will be able to sell their founder shares and private placement shares, as applicable, pursuant to Rule 144 without registration one year after KVSB has completed KVSB's initial business combination.

KVSB anticipates that following the consummation of the Business Combination, New Nextdoor will no longer be a shell company, and so, once the conditions set forth in the exceptions listed above are satisfied, Rule 144 will become available for the resale of the above noted restricted securities.

276

STOCKHOLDER PROPOSALS AND NOMINATIONS

Stockholder Proposals

New Nextdoor's Proposed Bylaws establish an advance notice procedure for stockholders who wish to present a proposal before an annual meeting of stockholders.

In the event that no annual meeting was held in the previous year or New Nextdoor holds its annual meeting of stockholders more than more than 30 days before or more than 70 days after the one-year anniversary of a preceding year's annual meeting, notice of a stockholder proposal must be not later than the 90th day or earlier than the 120th day prior to such annual meeting on the 10th day following the day on which public disclosure of the date of such annual meeting was first made. Nominations and proposals also must satisfy other requirements set forth in New Nextdoor's Proposed Bylaws.

Stockholder Director Nominees

New Nextdoor's Proposed Bylaws permit stockholders to nominate directors for election at an annual meeting or at a special meeting (but only if the election of directors is a matter specified in the notice of meeting given by or at the direction of the person calling such special meeting) of stockholders, subject to the provisions of New Nextdoor's Certificate of Incorporation. To nominate a director, the stockholder must provide the information required by New Nextdoor's Proposed Bylaws. In addition, the stockholder must give timely notice to New Nextdoor's secretary in accordance with New Nextdoor's Proposed Bylaws, which, in general, require that the notice be received by New Nextdoor's secretary within the time periods described above under '- Stockholder Proposals' for stockholder proposals.

LEGAL MATTERS

Latham & Watkins LLP, San Francisco, California, has passed upon the validity of the securities of New Nextdoor offered by this proxy statement/prospectus and certain other legal matters related to this proxy statement/prospectus.

CHANGE IN ACCOUNTANTS

(a)Dismissal of Independent Registered Public Accounting Firm

On August 8, 2021, the Audit Committee of the Board of Directors of Khosla Ventures Acquisition Co. II (the 'Company') approved the dismissal of Marcum LLP ('Marcum') as the Company's independent registered public accounting firm.

The reports of Marcum on the Company's financial statements as of February 1, 2021 and for the period January 29, 2021 through February 1, 2021 and the Company's balance sheet as of March 26, 2021 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principles, other than an explanatory paragraph relating to the Company's ability to continue as a going concern in the Company's audited financial statements as of February 1, 2021 and for the period January 29, 2021 through February 1, 2021.

During the period January 29, 2021 through February 1, 2021 and through the date of termination, August 8, 2021, there were no 'disagreements' with Marcum on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements if not resolved to the satisfaction of Marcum would have caused Marcum to make reference thereto in its reports on the financial statements for such period. During the period January 29, 2021 through February 1, 2021 and through August 8, 2021, there have been no 'reportable events' (as defined in Item 304(a)(1)(iv) and Item 304(a)(1)(v) of Registration S-K), other than a material weakness in internal controls over financial reporting related to the inaccurate accounting for the value of private placement shares, underwriting discounts and over-allotment public shares issued subsequent to the closing of the Company's initial public offering, as discussed further in the Company's amended Quarterly Report on Form 10-Q/A filed on July 19, 2021.

The Company provided Marcum with a copy of the disclosure it is making herein in response to Item 304(a) of Regulation S-K, and requested Marcum furnish the Company with a copy of its letter addressed to the Securities and Exchange Commission (the 'SEC'), pursuant to Item 304(a)(3) of Regulation S-K, stating whether or not Marcum agrees with the statements related to them made by the Company in this report. A copy of Marcum's letter dated August 12, 2021 is attached as Exhibit 16.1 to this registration statement.

(b)Newly Engaged Independent Registered Public Accounting Firm

On August 8, 2021, the Audit Committee approved the appointment of BDO LLP ('BDO') as the Company's new independent public accounting firm, effective immediately. Prior to engaging BDO, neither the Company, nor anyone on its behalf, consulted BDO regarding either (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered with respect to the consolidated financial statements of the Company, and no written report or oral advice was provided to the Company by BDO that was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue; or (ii) any matter that was the subject of a 'disagreement' (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a 'reportable event' (as that term is defined in Item 304(a)(1)(v) of Regulation S-K).

279

prospectus, given on the authority of said firm as experts in auditing and accounting. The report on the financial statements contains an explanatory paragraph regarding KVSB's ability to continue as a going concern.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors of

Khosla Ventures Acquisition Co. II

Opinion on the Financial Statements

We have audited the accompanying balance sheet of Khosla Ventures Acquisition Co. II (the 'Company') as of June 30, 2021, the related statement of operations, changes in common stock subject to possible redemption and stockholders' deficit and cash flows for the period from January 29, 2021 (inception) through June 30, 2021, and the related notes (collectively referred to as the 'financial statements'). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of June 30, 2021, and the results of its operations and its cash flows for the period from January 29, 2021 (inception) through June 30, 2021, in conformity with accounting principles generally accepted in the United States of America.

Going Concern Uncertainty

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the financial statements, the Company does not have sufficient cash and working capital to sustain its operations. These conditions raise substantial doubt about the Company's ability to continue as a going concern. Management's plans in regard to these matters are also described in Notes 1 and 9. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ('PCAOB') and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

/s/ BDO USA, LLP

We have served as the Company's auditor since 2021.

NOTES TO THE FINANCIAL STATEMENTS

JUNE 30, 2021

Note 1 - Description of Organization, Business Operations, Going Concern

Khosla Ventures Acquisition Co. II (the 'Company') is a blank check company incorporated in Delaware on January 29, 2021. The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (the 'Business Combination').

As of June, 30, 2021, the Company had not commenced any operations. All activity for the period from January 29, 2021 (inception) through June 30, 2021 relates to the Company's formation and Initial Public Offering (the 'Initial Public Offering') and expenses relating to the negotiation and consummation of its proposed initial Business Combination, in each case as described below. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company generates non-operating income in the form of interest income on cash and cash equivalents from the proceeds derived from the Initial Public Offering (as defined below). The Company has selected December 31 as its fiscal year end.

On March 26, 2021, the Company consummated its Initial Public Offering of 40,000,000 shares of Class A common stock of the Company, par value $0.0001 per share (each, a 'Public Share'), excluding additional Public Shares sold pursuant to the partial exercise of the underwriters' option to purchase additional Public Shares to cover over-allotments. The Public Shares were sold at a price of $10.00 per Public Share, generating gross proceeds to the Company of $400,000,000, which is described in Note 3. On March 26, 2021, the Company's underwriters exercised in part their option to purchase additional Public Shares in connection with its Initial Public Offering. The underwriters exercised their option to purchase an additional 1,634,412 Public Shares from the Company at a price of $10.00 per share less the underwriting discount. In total, the Company sold 41,634,412 Public Shares in connection with its Initial Public Offering. The Underwriters designated March 30, 2021 as the settlement date for such additional Public Shares pursuant to the Underwriting Agreement.

Simultaneously with the closing of the Initial Public Offering, we consummated the Private Placement of 1,100,000 Private Placement Shares at a price of $10.00 per Private Placement Share to the Sponsor, generating proceeds of $11,000,000. In connection with the underwriters' partial exercise of their over-allotment option, we also consummated the sale of an additional 32,688 Private Placement Shares at $10.00 per Private Placement Share, generating additional proceeds of $326,880. Total gross proceeds from the sale of Private Placement Shares was $11,326,880 as of June 30, 2021.

Following the closing of the Initial Public Offering on March 26, 2021, and the close of underwriters exercise of their overallotment option on March 30, 2021, an amount of 416,334,120 ($10 per Public Share) of the proceeds from the Initial Public Offering, including $14,572,044 of the underwriters' deferred discount was placed in a U.S.-based Trust Account at Goldman Sachs, maintained by Continental Stock Transfer & Trust Company, LLC, acting as trustee. Except with respect to interest earned on the funds in the Trust Account that may be released to the Company to pay its franchise and income taxes and expenses relating to the administration of the Trust Account, the proceeds from the Initial Public Offering and the Private Placements held in the Trust Account will not be released until the earliest of (a) the completion of the Company's initial business combination, (b) the redemption of any public shares properly tendered in connection with a stockholder vote to amend the Company's Amended and Restated Certificate of Incorporation (i) to modify the substance or timing of its obligation to redeem 100% of its public shares if the Company does not complete its initial business combination within 24 months from the closing of the Initial Public Offering (March 23, 2023) or 27 months (June 23, 2023), if we have executed a letter of intent, agreement in principle or definitive agreement for an initial Business Combination by March 23, 2023 (the 'Combination Period') or (ii) with respect to any other provisions relating to stockholders' rights or pre-initial business combination activity, and (c) the redemption of all of the Company's public shares if it is unable to complete its business combination within the Combination Period, subject to applicable law.

F-7

On July 6, 2021, the Company entered into an Agreement and Plan of Merger (the 'Merger Agreement') with Nextdoor, Inc., a Delaware corporation ('Nextdoor'), and Lorelei Merger Sub Inc., a Delaware corporation and a direct wholly owned subsidiary of KVSB ('Merger Sub').

The Company's management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of Private Placement Shares, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete one or more initial Business Combinations having an aggregate fair market value of at least 80% of the net assets held in the Trust Account (as defined below) (excluding the amount of deferred underwriting discounts held in Trust and taxes payable on the income earned on the Trust Account) at the time of the agreement to enter into the initial Business Combination. However, the Company only intends to complete a Business Combination if the post-transaction company owns or acquires 50% or more of the issued and outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act 1940, as amended (the 'Investment Company Act'). Upon the closing of the Initial Public Offering, management has agreed that an amount equal to at least $10.00 per Public Share sold in the Initial Public Offering, including the proceeds from the sale of the private placement shares and the sale of forward purchase shares, will be held in a trust account ('Trust Account') located in the United States with Continental Stock Transfer & Trust Company acting as trustee, and invested only in United States 'government securities' within the meaning of Section 2(a)(16) of the Investment Company Act having a maturity of 180 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations, as determined by the Company, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the Trust Account as described below.

The Company will provide its holders of the Public Shares (the 'Public Stockholders') with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Stockholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially anticipated to be $10.00 per share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations). The per-share amount to be distributed to Public Stockholders who redeem their Public Shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriters (as discussed in Note 5). These Public Shares were recorded at a redemption value and classified as temporary equity upon the completion of the Initial Public Offering, in accordance with Accounting Standards Codification ('ASC') 480 'Distinguishing Liabilities from Equity.' In such case, the Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon such consummation of a Business Combination and a majority of the shares voted are voted in favor of the Business Combination. If a stockholder vote is not required by law and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will, pursuant to the amended and restated certificate of incorporation, which was adopted by the Company upon the consummation of the Initial Public Offering (the 'Amended and Restated Certificate of Incorporation'), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (the 'SEC'), and file tender offer documents with the SEC prior to completing a Business Combination. If, however, a stockholder approval of the transactions is required by law, or the Company decides to obtain stockholder approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. Additionally, each Public Stockholder may elect to redeem their Public Shares irrespective of whether they vote for or against the transaction. If the Company seeks stockholder approval in connection with a Business Combination, the holders of the Founder Shares prior to this Initial Public Offering (the 'Initial Stockholders') have agreed to vote their Founder Shares (as defined in Note 4) and any Public Shares purchased during or after the Initial Public Offering in favor of a Business Combination. In addition, the Initial Stockholders have agreed to waive their redemption rights with respect to their Founder Shares and Public Shares in connection with the completion of a Business Combination.

F-8

The Certificate of Incorporation will provide that a Public Stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a 'group' (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the 'Exchange Act')), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the Public Shares, without the prior consent of the Company. The holders of the Founder Shares (the 'initial stockholders') have agreed not to propose an amendment to the Certificate of Incorporation (A) to modify the substance or timing of the Company's obligation to allow redemption in connection with a Business Combination or to redeem 100% of the Public Shares if the Company does not complete a Business Combination within the Combination Period (as defined below) or (B) with respect to any other provision relating to stockholders' rights or pre-initial Business Combination activity, unless the Company provides the Public Stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment.

If the Company is unable to complete a Business Combination within the Combination Period and the Company's stockholders have not amended the Certificate of Incorporation to extend such Combination Period, the Company will (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but no more than ten business days thereafter subject to lawfully available funds therefor, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes, if any (less up to $100,000 of interest to pay dissolution expenses) divided by the number of the then outstanding Public Shares, which redemption will completely extinguish Public Stockholders' rights as stockholders (including the right to receive further liquidation distributions, if any), subject to applicable law; and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the board of directors, liquidate and dissolve, subject in each case to the Company's obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

The Initial Stockholders have agreed to waive their liquidation rights with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the Initial Stockholders should acquire Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete a Business Combination within the Combination Period. The underwriters have agreed to waive their rights to their deferred underwriting commission (see Note 5) held in the Trust Account in the event the Company does not complete a Business Combination within in the Combination Period and, in such event, such amounts will be included with the funds held in the Trust Account that will be available to fund the redemption of the Company's Public Shares. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be only $10.00 per share initially held in the Trust Account. In order to protect the amounts held in the Trust Account, the Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or other similar agreement or business combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per public share and (ii) the actual amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company's indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the 'Securities Act'). In the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have vendors, service providers (except the Company's independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

F-9

Going Concern and Liquidity

As of June 30, 2021, the Company had $978,280 in its cash account, $416,350,445 in securities held in the Trust Account to be used for a Business Combination or to repurchase or redeem its common stock in connection therewith and working capital of $1,461,803. As of June 30, 2021, $6,327 of the amount on deposit in the Trust Account represented interest income, which is available for working capital needs.

If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to, suspending the pursuit of a Business Combination. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all.

As a result of the above, in connection with the Company's assessment of going concern considerations in accordance with Accounting Standards Update ('ASU') 2014-15, 'Disclosures of Uncertainties about an Entity's Ability to Continue as a Going Concern,' management has determined that the liquidity condition and date for mandatory liquidation and dissolution raise substantial doubt about the Company's ability to continue as a going concern through approximately one year from the date of filing. These financial statements do not include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should the Company be unable to continue as a going concern.

Prior to the consummation of the Initial Public Offering, the Company's liquidity needs have been satisfied through receipt of a $25,000 capital contribution from the Sponsor in exchange for the issuance of the Founder Shares to the Sponsor, and a $300,000 promissory note payable to the Sponsor.

Subsequent to the consummation of the Initial Public Offering, the Company received the net proceeds not held in the Trust Account of approximately $3,000,000. The Company fully repaid the note to the Sponsor in April 2021. In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company's officers and directors may, but are not obligated to, loan the Company Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans.

The Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender's discretion, up to $1,500,000 of such Working Capital Loans may be convertible into shares of the post-transaction company at $10.00 per share at the option of the lender. As of June 30, 2021, the Company has no borrowings under the Working Capital Loans.

Risks and Uncertainties

Management continues to evaluate the impact of the COVID-19 pandemic and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company's financial position, results of its operations and/or search for a target company, the specific impact is not readily determinable as of the date of the financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Note 2 - Summary of Significant Accounting Policies

Basis of Presentation

The accompanying financial statements are presented in conformity with accounting principles generally accepted in the United States of America ('GAAP') and pursuant to the rules and regulations of the SEC.

The accompanying unaudited statement of operations and changes in common stock subject to possible redemption and stockholders' deficit for the three-month period ended June 30, 2021 are presented in U.S. dollars in conformity with GAAP and pursuant to the rules and regulations of the SEC and reflect all adjustments, consisting only of normal recurring adjustments, which are, in the opinion of management necessary for the fair presentation of the results of operations for the period presented. The interim results for the period ended June 30, 2021, are not necessarily indicative of the results to be expected for the year ending December 31, 2021, or for any future periods.

F-10

Emerging Growth Company

The Company is an 'emerging growth company,' as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the 'JOBS Act'), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company's financial statements with another public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Cash and Cash Equivalents

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had $978,280 in cash and no cash equivalents, outside of the funds held in the Trust Account, as of June 30, 2021.

Marketable Securities Held in Trust Account

As of June 30, 2021, the assets held in the Trust Account were invested in Goldman Sachs funds.

Common Stock Subject to Possible Redemption

The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in ASC Topic 480.

Conditionally redeemable common stock (including common stock that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company's control) are classified as temporary equity. At all other times, common stock is classified as stockholders' equity. The Company's Class A common stock feature contains certain redemption rights that are considered to be outside of the Company's control and subject to occurrence of uncertain future events. Accordingly, Class A common stock subject to possible redemption are classified as temporary equity, outside of the stockholders' equity section of the Company's balance sheet. Accordingly, as of June 30, 2021, 41,634,412 shares of Class A common stock subject to possible redemption is presented at redemption value as temporary equity, outside of the stockholders' equity section of the Company's balance sheet.

The Class A common stock subject to possible redemption are subject to the subsequent measurement guidance in ASC Topic 480-10-S99. Under such guidance, the Company must subsequently measure the shares to their redemption amount because, as a result of the allocation of net proceeds to transaction costs, the initial carrying amount of the common stock is less than $10.00 per share. In accordance with the guidance, the Company has elected to measure the common stock subject to possible redemption to their redemption amount (i.e., $10.00 per share) immediately as if the end of the first reporting period after the Initial Public Offering, March 26, 2021, was the redemption date. Such changes are reflected in additional paid-in capital, or in the absence of additional paid-in

F-11

capital, in accumulated deficit. From the period beginning January 29, 2021 (inception) through June 30, 2021, the Company recorded an accretion of $23,576,984, of which $11,338,767 was recorded in additional paid-in capital and $12,238,217 was recorded in accumulated deficit.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist of a cash account in a financial institution which, at times may exceed the Federal depository insurance coverage of $250,000. As of June 30, 2021, the Company had not experienced losses on this account and management believes the Company is not exposed to significant risks on such account.

Financial Instruments

The fair value of the Company's assets and liabilities, which qualify as financial instruments under ASC Topic 820, 'Fair Value Measurement,' approximates the carrying amounts represented in the balance sheet.

Derivative Financial Instruments

The Company accounts for derivative financial instruments in accordance with ASC Topic 815, 'Derivatives and Hedging'. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value upon issuance and remeasured at each reporting date, with changes in the fair value reported in the statements of operations. The classification of derivative financial instruments is evaluated at the end of each reporting period.

Fair Value Measurements

The fair value of the Company's assets and liabilities, which qualify as financial instruments under ASC Topic 820 approximates the carrying amounts represented in the balance sheet.

The fair value hierarchy is categorized into three levels based on the inputs as follows:

•Level 1: Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

•Level 2: Observable inputs other than Level 1 inputs. Example of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active.

•Level 3: Unobservable inputs based on our assessment of the assumptions that market participants would use in pricing the asset or liability.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires the Company's management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities during the reporting period. Actual results could differ from those estimates.

Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statement, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.

Offering Costs

Offering costs consist of legal, accounting, and other costs incurred through the balance sheet date that are directly related to the Initial Public Offering and were charged to temporary equity upon completion of the Initial

F-12

Public Offering. Offering costs were $23,576,984 for the period from January 29, 2021 (inception) through June 30, 2021.

Income Taxes

The Company complies with the accounting and reporting requirements of ASC Topic 740, 'Income Taxes,' which requires an asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed for differences between the financial statements and tax bases of assets and liabilities that will result in future taxable or deductible amounts, based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. As of June 30, 2021, the deferred tax asset is de minimis.

ASC Topic 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. The Company's management determined that the United States is the Company's only major tax jurisdiction.

The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of June 30, 2021. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception.

Net Loss Per Share of Common Stock

The Company complies with accounting and disclosure requirements of ASC Topic 260, 'Earnings Per Share.' Net loss per share is computed by dividing net loss by the weighted average number of common stock outstanding during the period, excluding common stock shares subject to forfeiture.

Class K common stock will convert into Class A common stock after the initial Business Combination only to the extent certain triggering events occur prior to the 10th anniversary of the initial Business Combination, including three equal triggering events based on the Company's stock trading at $20.00, $25.00 and $30.00 per share following the first anniversary of the closing of the initial Business Combination and also upon specified strategic transactions. The Company has not considered the effect of the Class K common stock in the calculation of diluted loss per share since the conversion of Class K common stock into Class A common stock is contingent upon the occurrence of future events.

Class B shares and Private Placement Shares are included in the calculation of non-redeemable earnings per share.

The Company's statements of operations include a presentation of income (loss) per share for shares of common stock subject to possible redemption in a manner similar to the two-class method of income (loss) per share. With respect to the accretion of the Class A common stock subject to possible redemption and consistent with ASC Topic 480-10-S99-3A, the Company has treated the accretion in the same manner as a dividend in the calculation of net income/(loss) per common stock. As of June 30, 2021, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into common stock and then share in the earnings of the Company. As a result, diluted loss per share is the same as basic loss per share for the period presented.

Recent Accounting Pronouncements

Management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the accompanying financial statements.

Note 3 - Initial Public Offering

Pursuant to the Initial Public Offering, the Company sold 40,000,000 Public Shares at a purchase price of $10.00 per Public Share, excluding Public Shares sold pursuant to the partial exercise of the underwriters' option to purchase additional Public Shares to cover over-allotments (See Note 5).

Substantially concurrent with the closing of the Initial Public Offering, the Company completed the private sale of 1,100,000 shares of Class A common stock of the Company, par value $0.0001 per share (the 'Private Placement Shares') at a purchase price of $10.00 per Private Placement Shares, to the Company's sponsor, Khosla Ventures SPAC Sponsor II LLC, generating aggregate gross proceeds to the Company of $11,000,000. The underwriters exercised their option to purchase an additional 1,634,412 shares of Class A common stock from the Company at a price of $10.00 per share less the underwriting discount. In total, the Company sold 41,634,412 shares of Class A common stock in connection with its Initial Public Offering. Subsequent to the Initial Public Offering, an additional $16,344,118 was placed in the Trust Account, comprised of proceeds from the sale of additional Class A common stock pursuant to the exercise of the underwriters' over-allotment option, which settled on March 30, 2021.

Note 4 - Related Party Transactions

Promissory Note - Related Parties

On February 8, 2021, the Company issued a promissory note (the 'Promissory Note') to the Sponsor and an affiliate of the Sponsor, pursuant to which the Company could borrow up to an aggregate principal amount of $300,000. The Promissory Note was non-interest bearing and payable on the earlier of (i) December 31, 2021 and (ii) the completion of the Initial Public Offering. The outstanding balance under the Promissory Note at June 30, 2021 was $5,300.

Founder Shares

On January 29, 2021, the Sponsor acquired 10,000,000 Founder Shares (the 'Founder Shares') for an aggregate purchase price of $25,000, consisting of 5,000,000 Class B Founder Shares (also known as 'Class B common stock') and 5,000,000 Class K Founder Shares (also known as 'Class K common stock'). Prior to the initial investment in the Company of $25,000 by the Sponsor, the Company had no assets, tangible or intangible. The per share purchase price of the Founder Shares was determined by dividing the amount of cash contributed to the

F-14

Company by the aggregate number of Founder Shares issued. On March 10, 2021, the Sponsor entered into a security assignment agreement with three of the Company's independent directors and assigned 120,000 shares of Class B common stock at an aggregate price of $300.

Class B Common Stock

The Class B common stock will automatically convert into shares of Class A common stock on the first business day following the completion of our initial business combination, at a ratio such that the number of shares of Class A common stock issuable upon conversion of all Class B common stock will equal, in the aggregate on an as-converted basis, 15% of the sum of (i) the total number of all shares of Class A common stock issued and outstanding upon completion of this offering (including any over-allotment shares if the underwriters exercise their overallotment option), plus (ii) the total number of shares of Class A common stock issued or deemed issued or issuable upon conversion of the Class B common stock plus (iii) unless waived, the total number of shares of Class A common stock issued or deemed issued or issuable upon conversion or exercise of any equity-linked securities (as defined herein) or rights issued or deemed issued, by the Company in connection with or in relation to the consummation of the initial business combination, excluding (x) any shares of Class A common stock or equity-linked securities exercisable for or convertible into shares of Class A common stock issued, deemed issued, or to be issued, to any seller in the initial business combination, (y) any shares of Class A common stock issuable upon conversion of the Class K Founder Shares and (z) any Private Placement Shares. Prior to our initial business combination, only holders of shares of our Class B common stock will be entitled to vote on the appointment of directors.

Class K Founder Shares

The Class K Founder Shares will convert into shares of Class A common stock after the initial business combination only to the extent certain triggering events occur prior to the 10th anniversary of the initial business combination, including three equal triggering events based on our stock trading at $20.00, $25.00 and $30.00 per share following the first anniversary of the closing of our initial business combination and also upon specified strategic transactions, in each case, as described in this prospectus. The Class K Founder Shares will be convertible into shares of Class A common stock at a ratio such that the number of shares of Class A common stock issuable upon conversion of all founder shares (including both Class B common stock and Class K Founder Shares) will equal, in the aggregate on an as-converted basis, 30% of the sum of (i) the total number of all shares of Class A common stock issued and outstanding upon completion of this offering (including any over-allotment shares if the underwriters exercise their overallotment option), plus (ii) the total number of shares of Class A common stock issued or deemed issued or issuable upon conversion of the Class B common stock and Class K Founder Shares plus (iii) unless waived, the total number of shares of Class A common stock issued or deemed issued or issuable upon conversion or exercise of any equity-linked securities (as defined herein) or rights issued or deemed issued, by the Company in connection with or in relation to the consummation of the initial business combination, excluding (x) any shares of Class A common stock or equity-linked securities exercisable for or convertible into shares of Class A common stock issued, deemed issued, or to be issued, to any seller in the initial business combination and (y) any Private Placement Shares. Prior to our initial business combination, only holders of shares of our Class B common stock were entitled to vote on the appointment of directors.

The Company accounts for the Class K Founder Shares as equity linked instruments. Based on the guidance in ASC Topic 815, certain adjustments to the settlement amount of the Class K Founder Shares are based on a variable that is not an input to the fair value of a 'fixed-for-fixed' option as defined under ASC Topic 815-40. The Class K Founder Shares are recorded as liabilities as these shares are not considered indexed to the Company's own stock and not eligible for an exception from derivative accounting.

Working Capital Loan

In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company's officers and directors may, but are not obligated to, loan the Company funds as may be required ('Working Capital Loans'). If the Company completes a Business Combination, the Company would repay the Working Capital Loans out of the proceeds of the Trust Account released to the

F-15

Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. To date, the Company had no borrowings under the Working Capital Loans.

Private Placement Shares

Simultaneously with the closing of the Initial Public Offering, the Sponsor has purchased 1,100,000 Class A common stock at a price of $10.00 per stock in a private placement for an aggregate purchase price of $11,000,000. In connection with the underwriters' partial exercise of their over-allotment option that closed on March 30, 2021, the Company also consummated the sale of an additional 32,688 Private Placement Shares at $10.00 per Private Placement Share, generating total proceeds of $326,880. The total proceeds from the sale of Private Placement Shares is $11,326,880. The Private Placement Shares are identical to the shares of Class A common stock sold in this offering, subject to certain limited exceptions. The Private Placement Shares holders do not have the option to redeem their Class A shares and as a result, the proceeds received in connection with the Initial Public Offering are excluded from temporary equity. The par value of these shares and related additional paid in capital are classified as permanent equity in the Company's financial statements.

The initial stockholders agreed, subject to limited exceptions, not to transfer, assign or sell any of their Private Placement Shares until 30 days after the completion of the initial business combination.

Forward Purchase Agreement

The Company has entered into a forward-purchase agreement pursuant to which the Sponsor agreed to purchase an aggregate of up to 1,000,000 shares of our Class A common stock (the 'forward-purchase shares') for $10.00 per share, or an aggregate maximum amount of $10,000,000, in a private placement that would close simultaneously with the closing of the initial business combination. The proceeds from the sale of these forward-purchase shares, together with the amounts available to the Company from the Trust Account (after giving effect to any redemptions of public shares) and any other equity or debt financing obtained by the Company in connection with the business combination, will be used to satisfy the cash requirements of the business combination, including funding the purchase price and paying expenses and retaining specified amounts to be used by the post-business combination company for working capital or other purposes. To the extent that the amounts available from the Trust Account and other financing are sufficient for such cash requirements, the Khosla Entities may purchase less than 1,000,000 forward-purchase shares. The forward-purchase shares would be identical to the public shares being sold in this offering, except the forward-purchase shares would be subject to transfer restrictions and certain registration rights, as described herein. The Company performed an assessment in accordance with ASC Topic 480 and ASC Topic 815, to conclude whether the forward-purchase shares constitute a liability and a derivative such that it will be fair valued separately from the Company's common stock. The Company concludes that the forward-purchase shares should be equity-classified and its embedded features should not be bifurcated.

Note 5 - Commitments & Contingencies

Registration Rights

The holders of the Founder Shares and Private Placement Shares are entitled to registration rights pursuant to the registration agreement signed prior to the consummation of the Initial Public Offering. The holders are entitled to certain demand and 'piggyback' registration rights. However, the registration rights agreement provides that the Company will not be required to effect or permit any registration or cause any registration statements to become effective until termination of the applicable lock-up period.

Underwriting Agreement

The Company granted the underwriters an option to cover over-allotments and for market stabilization purposes. The over-allotment option entitled the underwriters to purchase on a pro rata basis up to 6,000,000

F-16

additional Public Shares at the Initial Public Offering price, less the underwriting discounts and commissions. On March 26, 2021, the Company's underwriters exercised in part their option to purchase additional Public Shares in connection with its Initial Public Offering. The underwriters exercised their option to purchase an additional 1,634,412 Public Shares from the Company at a price of $10.00 per share less the underwriting discount. In total, the Company sold 41,634,412 Public Shares in connection with its Initial Public Offering. This transaction settled on March 30, 2021.

The underwriters are entitled to a deferred fee of $14,572,044. The deferred fee will be forfeited by the underwriters solely in the event that the Company fails to complete a Business Combination, subject to the terms of the underwriting agreement.

Note 6 - Stockholders' Deficit

Preferred Stock - The Company is authorized to issue 1,000,000 preferred stock, par value $0.0001 per share. As of June 30, 2021, there were no shares of preferred stock issued or outstanding.

Class A Common Stock - The Company is authorized to issue 200,000,000 Class A common stock with a par value of $0.0001 per share. Holders of the Company's Class A common stock are entitled to one vote for each share. As of June 30, 2021, there were 1,132,688 shares of Class A common stock issued and outstanding, excluding 41,634,412 shares of Class A common stock subject to possible redemption.

Class B Common Stock - The Company is authorized to issue 30,000,000 Class B common stock with a par value of $0.0001 per share. As of June 30, 2021, 5,000,000 Class B common stock were issued and outstanding.

Common stockholders of record are entitled to one vote for each share held on all matters to be voted on by stockholders. Except as described below, holders of Class A common stock and holders of Class B common stock will vote together as a single class on all matters submitted to a vote of the stockholders except as required by law.

Note 7 - Fair Value Measurements

The following table presents information about the Company's assets that are measured at fair value on a recurring basis at June 30, 2021, including the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value.


Description	Level	June 30, 2021
Assets:
Marketable securities held in Trust Account	1	$	416,350,445

Liabilities:
Derivative liability - Class K Founder Shares	3	$	16,550,000

Class K Founder common stock

Class K common stock was accounted for as a liability in accordance with ASC Topic 815 and presented as derivative liability on the accompanying June 30, 2021, balance sheet. The derivative liability was measured at fair value at inception and on a recurring basis, which changes in fair value presented within change in fair value of derivative liability in the statements of operations. In order to capture the market conditions associated with the Class K common stock liability, the Company applied an approach that incorporated a Monte Carlo simulation, which involved random iterations of future stock-price paths over the contractual life of the Class K common stock. Based on assumptions regarding potential changes in control of the Company, and the probability distribution of outcomes, the payoff to the holder was determined based on the achievement of the various market thresholds within each simulated path. The present value of the payoff in each simulated trial is calculated, and the fair value of the liability is determined by taking the average of all present values.

F-17

The key inputs into the Monte-Carlo simulation model for Class K common stock were as follows as of the issuance date and as of June 30, 2021:


Input	January 29, 2021 (Inception)	June 30, 2021
Risk-free interest rate	1.16	%	1.48	%
Term to business combination	0.9 years	0.5 years
Expected volatility	21.0	%	15.0	%
Stock Price	$	10.00	$	9.94

The following table presents a summary of the changes in the fair value of the Class K Founder Shares liability, a Level 3 liability, measured on a recurring basis, as of June 30, 2021:


Class K Founder Shares Derivative Liability
Fair value, January 29, 2021 (inception)	$	36,550,000
Change in fair value of Class K Founder Shares liability	(22,950,000)
Fair value, March 31, 2021 (unaudited)	13,600,000
Change in fair value of Class K Founder Shares liability	2,950,000
Fair value, June 30, 2021 (audited)	$	16,550,000

There were no transfers to and from Levels 1, 2, and 3 during the three months ended June 30, 2021, and the period from January 29, 2021 (inception) through June 30, 2021.

Note 8 - Subsequent Events

The Company evaluated subsequent events and transactions that occurred after the balance sheet date through the date the financial statements were issued. Based upon this review, other than as described below, the Company did not identify any subsequent events that would have required adjustment or disclosure in the financial statements other than the following.

On July 6, 2021, concurrently with the execution of the Merger Agreement, we entered into subscription agreements (the 'Subscription Agreements') with certain investors (collectively, the 'PIPE Investors'), pursuant to, and on the terms and subject to the conditions of which, the PIPE Investors have independently subscribed for an aggregate of 27 million shares of Class A common stock for an aggregate purchase price equal to $270 million (the 'PIPE Investment'). The PIPE Investment will be consummated substantially concurrently with the consummation of the transactions contemplated by the Merger Agreement.

Notes to the Consolidated Financial Statements

Note 1. Description of Business

Nextdoor, Inc. ('Nextdoor' or the 'Company'), was incorporated in Delaware in 2007 and is headquartered in San Francisco, California. Nextdoor's purpose is to cultivate a kinder world where everyone has a neighborhood they can rely on. That purpose enables the Company's mission to be the neighborhood hub for trusted connections and the exchange of helpful information, goods, and services. The Company changed its name in March 2019 to Nextdoor, Inc. from Nextdoor.com, Inc.

Note 2. Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ('GAAP') and include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The Company's fiscal year ends on December 31.

Unaudited Interim Consolidated Financial Information

The accompanying interim consolidated balance sheet as of June 30, 2021, the interim consolidated statements of operations, comprehensive loss, redeemable convertible preferred stock and stockholders' deficit, and cash flows for the six months ended June 30, 2021 and 2020 and the related notes to such interim consolidated financial statements are unaudited. These unaudited interim consolidated financial statements have been prepared in accordance with GAAP. In management's opinion, the unaudited interim consolidated financial statements have been prepared on the same basis as the annual financial statements and reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the Company's financial position as of June 30, 2021 and the Company's consolidated results of operations and cash flows for the six months ended June 30, 2021 and 2020. The consolidated results of operations for the six months ended June 30, 2021 are not necessarily indicative of the results to be expected for the full year ending December 31, 2021 or any other future interim or annual period.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Estimates include, but are not limited to, valuation of financial instruments, valuation of common stock and stock-based awards, revenue recognition, collectability of accounts receivable, valuation of acquired intangible assets and goodwill, useful lives of intangible assets, useful lives of property and equipment, the incremental borrowing rate applied in lease accounting, income taxes and deferred income tax assets and associated valuation allowances. The Company bases these estimates and assumptions on historical experience and various other assumptions that it considers reasonable. The actual results could differ materially from these estimates.

Foreign Currency

On January 1, 2020 the Company concluded that the functional currency of its foreign subsidiaries had changed from the U.S. dollar to the local currency of the economic environment in which it primarily operates. This change occurred due to changes in the Company's operating structure and global operating model. The Company accounted for the change in functional currency prospectively. The financial statements of these subsidiaries are translated into U.S. dollars using period-end rates of exchange for assets and liabilities, historical rates of exchange for equity, and average rates of exchange for revenue and expenses. For the six months ended June 30, 2021 and 2020 (unaudited) and for the year ended December 31, 2020, translation gains (losses) are recorded in accumulated other comprehensive income (loss) as a component of stockholders' deficit and unrealized foreign exchange gains and losses due to re-measurement of monetary assets and liabilities denominated in non-functional currencies as well as realized foreign exchange gains and losses on foreign exchange transactions are recorded in other income (expense),

F-26

net in the consolidated statements of operations. For the year ended December 31, 2019, foreign currency gains or losses were recorded in the consolidated statements of operations.

Cash and Cash Equivalents

Cash and cash equivalents consist of highly liquid investments with insignificant interest rate risk and original maturities of three months or less at the time of purchase. Cash and cash equivalents include demand deposits and money market accounts. Interest is accrued as earned. Cash and cash equivalents are recorded at cost, which approximates fair value.

Marketable Securities

The Company's marketable securities are comprised of certificates of deposit ('CDs'), commercial paper, corporate securities, U.S. Treasury securities, and asset-backed securities. The Company determines the appropriate classification of its investments at the time of purchase and reevaluates such designation at each balance sheet date. The Company has classified and accounted for its investments as available-for-sale securities as the Company may sell these securities at any time for use in its current operations or for other purposes, even prior to maturity. As a result, the Company classifies its investments, including securities with stated maturities beyond 12 months, within current assets on the consolidated balance sheets.

Available-for-sale securities are recorded at fair value each reporting period. Unrealized gains and losses on these investments are reported as a separate component of accumulated other comprehensive income (loss) on the consolidated balance sheets until realized. Interest income is reported within interest income in the consolidated statements of operations. The Company periodically evaluates its marketable securities to assess whether those with unrealized loss positions are other-than-temporarily impaired. The Company considers various factors in determining whether to recognize an impairment charge, including the length of time the investment has been in a loss position, the extent to which the fair value is less than the Company's cost basis, the financial condition and near-term prospects of the investee. Realized gains and losses are determined based on the specific identification method and are reported in other income (expense), net in the consolidated statements of operations. If the Company determines that the decline in an investment's fair value is other than temporary, the difference is recognized as an impairment loss in the consolidated statements of operations. The Company did not consider any of its investments to be other-than-temporarily impaired for the six months ended June 30, 2021 and 2020 (unaudited) and the years ended December 31, 2020 and 2019.

Fair Value Measurements

The Company accounts for certain assets and liabilities at fair value, which is the expected exchange price that would be received for an asset or an exit price paid to transfer a liability in an orderly transaction between market participants on the measurement date. Assets and liabilities measured at fair value are classified into the following categories based on the degree to which the inputs the Company uses to measure the fair values are observable in active markets. The Company uses the most observable inputs available when measuring fair value.

•Level 1: Observable inputs such as unadjusted quoted prices for identical assets or liabilities in active markets;

•Level 2: Observable inputs such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical assets or liabilities in inactive markets, or inputs that are derived principally from or corroborated by observable market data or other means; and

•Level 3: Unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities.

Accounts Receivable and Allowance for Doubtful Accounts

The Company records accounts receivable at the original invoiced amount. The Company maintains an allowance for doubtful accounts for any receivables it may be unable to collect and reduces the allowance when it determines that it will be unable to collect specific receivables. The Company determines the allowance based on its

F-27

receivables' age, the customers' credit quality, and current economic conditions, among other factors that may affect the customers' ability to pay.

Restricted Cash

The Company's restricted cash balance is primarily invested in a savings account and pledged as collateral for standby letters of credit as security deposits for the Company's office leases. As of June 30, 2021 (unaudited) and December 31, 2020 and 2019, the Company had restricted cash balances of $0 million, $1.1 million, and $7.0 million, respectively.

Property and Equipment

Property and equipment are recorded at cost, less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets as follows:


Estimated Useful Life
Computer equipment and software	3 years
Furniture and fixtures	5 years
Leasehold improvements	Shorter of the estimated useful life of 5 years or the lease term

Maintenance and repair costs are expensed as incurred.

Capitalized Internal-use Software

The Company capitalizes internal-use software costs when preliminary development efforts are successfully completed, management has authorized and committed project funding, and it is probable that the project will be completed, and the software will be used as intended. Costs related to preliminary project activities and post-implementation activities are expensed as incurred and costs related to the application development stage are capitalized. Capitalized costs are recorded as part of property and equipment, net. The capitalized costs related to internal-use software are amortized on a straight-line basis over an estimated useful life of two to three years. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. The Company did not capitalize any internal-use software costs during the six months ended June 30, 2021 (unaudited) and capitalized $0.2 million and $0.1 million for the years ended December 31, 2020 and 2019, respectively.

Business Combinations

The Company includes the results of operations of the businesses that it acquires from the date of acquisition. The Company accounts for its acquisitions using the acquisition method of accounting. The Company allocates the fair value of purchase consideration to the tangible assets acquired, liabilities assumed, and intangible assets acquired, based on their estimated fair values. The excess of the fair value of purchase consideration over the values of these identifiable assets and liabilities is recorded as goodwill. When determining the fair value of assets acquired and liabilities assumed, management makes significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain identifiable assets include, but are not limited to, expected long-term market growth, future expected operating expenses, appropriate discount rates, and useful lives. Management's estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. Acquisition costs, such as legal and consulting fees, are expensed as incurred. During the measurement period, the Company may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, which is not to exceed one year from the acquisition date, any subsequent adjustments are recorded in the consolidated statements of operations. See Note 3 - Acquisitions for additional information regarding the Company's acquisition.

F-28

Goodwill and Other Acquired Intangible Assets

Goodwill represents the excess of the purchase price over the fair value of net assets acquired in connection with business combinations accounted for using the acquisition method of accounting. Goodwill is not amortized, but is tested for impairment at least annually, in the fourth quarter, or whenever events or changes in circumstances indicate that goodwill might be impaired. For all periods presented the Company had one reporting unit. The Company's test for goodwill impairment starts with a qualitative assessment to determine whether it is necessary to perform the quantitative goodwill impairment test. If the Company determines, based on the qualitative factors, that the fair value of the reporting unit is more likely than not to be less than the carrying amount, then a quantitative goodwill impairment test is required. There was no impairment of goodwill recorded for the six months ended June 30, 2021 and 2020 (unaudited) and for the years ended December 31, 2020 and 2019.

Intangible assets consist of identifiable intangible assets, including customer relationships and developed technology, resulting from the Company's acquisitions. Acquired intangible assets are recorded at cost, net of accumulated amortization. Intangible assets are amortized on a straight-line basis over their estimated useful lives. Amortization costs are recorded in sales and marketing in the consolidated statements of operations.

Impairment of Long-Lived Assets

Property and equipment and other long-lived assets, such as finite-lived intangible assets, subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of these assets is measured by a comparison of the carrying amounts to the future undiscounted cash flows the assets are expected to generate. If impairment is indicated, an impairment loss is recognized as the amount by which the carrying amount exceeds the fair value. No impairment was required for long-lived assets for the six months ended June 30, 2021 and 2020 (unaudited) and for the years ended December 31, 2020 and 2019.

Leases

Results and disclosure requirements for all periods presented are presented under ASU 2016-02, Leases ('Topic 842').

The Company has various lease agreements related to real estate that are all classified as operating leases. At the inception of the Company's contracts it determines if the contract is or contains a lease. A contract is or contains a lease if it conveys the right to control the use of an identified asset for a period of time in exchange for consideration. For leases that have greater than a 12-month lease term, right-of-use ('ROU') assets and operating lease liabilities are recognized on the consolidated balance sheets at commencement date based on the present value of remaining fixed lease payments.

Certain of the Company's leases include options to extend the lease, with renewal terms that can extend the lease term from one month to five years. If the Company is reasonably certain to exercise an option to extend a lease, the extension period is included as part of the ROU asset and the operating lease liability.

When the discount rate implicit in the lease cannot be readily determined, the Company uses its incremental borrowing rate at lease commencement in order to discount lease payments to present value for purposes of performing lease classification tests and measuring the lease liability. The Company's incremental borrowing rate represents the rate of interest the Company would have to pay to borrow, on a collateralized basis, over a similar term an amount equal to the lease payments in a similar economic environment.

The operating lease ROU asset also includes accrued lease expense resulting from the straight-line accounting under prior accounting methods, which is now being amortized over the remaining life of the lease.

The Company's lease payments are largely fixed. Variable lease payments exist in circumstances such as payments for property tax, insurance, and common area maintenance. Variable lease payments are recognized in operating expense in the period in which the obligation for those payments are incurred. Certain of the Company's leases include an option to early terminate the lease. The Company's leases may contain early termination options

F-29

which may result in an early termination fee. The Company early terminated one of its leases in October 2020 and incurred an early termination fee of $0.1 million. The Company has a significant lease for its new headquarters in San Francisco, California, which does not include an option to early terminate. The first portion of the lease commenced in June 2020 and the second, and final portion of the lease, commenced in January 2021.

For the Company's leases, it has elected to not apply the recognition requirements to leases of twelve months or less. These leases are expensed on a straight-line basis and no operating lease liability will be recorded.

Deferred Transaction Costs

Deferred transaction costs, which consist of direct incremental legal, accounting, consulting, and other fees related to the Company's proposed merger with Lorelei Merger Sub Inc. ('Merger Sub'), a wholly owned subsidiary of Khosla Ventures Acquisition Co. II ('KVSB') (the 'Merger') are capitalized in other assets on the consolidated balance sheets. The deferred transaction costs will be charged to stockholders' equity upon the completion of the Merger. In the event the planned Merger is terminated, the deferred transaction costs will be immediately expensed in the consolidated statements of operations. Deferred transaction costs as of June 30, 2021 (unaudited) were $2.1 million. There were no deferred transaction costs recorded as of December 31, 2020 and 2019.

Concentration of Credit and Customer Risks

Financial instruments that are exposed to concentrations of credit risk consist principally of cash and cash equivalents, marketable securities and accounts receivable. The Company maintains cash and cash equivalents and marketable securities with domestic and foreign financial institutions and at times may exceed federally insured limits. The Company performs periodic evaluations of the relative credit standing of these institutions. The Company maintains investments in U.S. government debt and agency securities, corporate debt securities, certificates of deposit, and commercial paper that carry high credit ratings and accordingly, minimal credit risk exists with respect to these balances.

No customer represented 10% or more of accounts receivable or revenue as of and for the year ended December 31, 2020. Two customers represented 10% and 13%, respectively, of accounts receivable as of December 31, 2019. These same two customers each represented 12% of revenue for the year ended December 31, 2019.

Revenue Recognition

The Company generates a majority of its revenue from the delivery of advertising services.

The Company determines revenue recognition through the following steps:

(1)Identification of the contract, or contracts, with a customer

(2)Identification of the performance obligations in the contract

(3)Determination of the transaction price

(4)Allocation of the transaction price to the performance obligations in the contract

(5)Recognition of revenue when, or as, the Company satisfies a performance obligation

The Company recognizes advertising revenue after satisfying its contractual performance obligation, which, for the majority of its advertising arrangements, is when an advertising impression is displayed to users. None of the Company's arrangements contain minimum impression guarantees. The Company typically bills advertisers on a monthly basis and the payment terms vary by customer type and location. The Company has other advertising arrangements for the sale of local sponsorship and local deals which are typically fixed-fee arrangements and revenue is recognized on a straight-line basis over the non-cancellable contractual term of the agreement, generally beginning on the date its service is made available to the customer.

F-30

Deferred Revenue

In certain advertising arrangements the Company requires payment upfront from its customers. The Company records deferred revenue when it collects cash from customers in advance of revenue recognition. As of June 30, 2021 (unaudited) and December 31, 2020 and 2019, deferred revenue was $3.6 million, $2.6 million, and $0.7 million, respectively, and included within accrued expenses and other current liabilities on the consolidated balance sheets.

For the six months ended June 30, 2021 and 2020 (unaudited), revenue recognized from deferred revenue at the beginning of each period was $1.8 million and $0.5 million, respectively. For the years ended December 31, 2020 and 2019, revenue recognized from deferred revenue at the beginning of each year was $0.7 million and $0.2 million, respectively.

Practical Expedients and Exemptions

The Company expenses sales commissions as incurred because the expected period of benefit is less than one year. These costs are recorded within sales and marketing expenses in the consolidated statements of operations.

The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which it recognizes revenue at the amount to which it has the right to invoice for services performed.

Cost of Revenue

Cost of revenue consists primarily of expenses associated with the delivery of the Company's revenue generating activities, including third-party costs of hosting its platform and allocated personnel-related costs, including salaries, benefits and stock-based compensation for employees engaged in development of its revenue generating products. Cost of revenue also includes third-party costs associated with delivering and supporting its advertising products and credit card transaction fees related to processing customer transactions.

Research and Development

Research and development expenses consist primarily of personnel-related costs, including salaries, benefits and stock-based compensation for its employees engaged in research and development, as well as costs for consultants, contractors and third-party software. In addition, allocated overhead costs, such as facilities, information technology, and depreciation are included in research and development expenses.

Sales and Marketing

Sales and marketing expenses consist primarily of personnel-related costs and other costs which include salaries, commissions, benefits, and stock-based compensation for employees engaged in sales and marketing activities as well as other costs including third-party consulting, public relations, allocated overhead costs, and amortization of acquired intangible assets. Sales and marketing expenses also include brand and performance marketing for both user and small and mid-sized customer acquisition, and neighbor services, which includes personnel-related costs for the Company's neighbor support team, its outsourced neighbor support function, and verification costs.

General and Administrative

General and administrative expenses consist primarily of personnel-related costs, including salaries, benefits, and stock-based compensation, for certain executives, finance, legal, information technology, human resources, and other administrative employees. In addition, general and administrative expenses include fees and costs for professional services, including consulting, third-party legal and accounting services, and allocated overhead costs.

F-31

Advertising Costs

Advertising costs which consist primarily of brand and performance marketing are expensed as incurred and are included in sales and marketing expense in the consolidated statements of operations. Total advertising costs incurred were $16.5 million and $12.6 million for the six months ended June 30, 2021 and 2020 (unaudited), respectively, and $23.7 million and $38.9 million for the years ended December 31, 2020 and 2019, respectively.

Income Taxes

The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the consolidated financial statements or in the Company's tax returns. Deferred income taxes are recognized for differences between financial reporting and tax bases of assets and liabilities at the enacted statutory tax rates in effect for the years in which the temporary differences are expected to reverse. Management makes an assessment of the likelihood that the resulting deferred tax assets will be realized. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. Due to the Company's historical operating performance and the recorded cumulative net losses in prior fiscal periods, the U.S. net deferred tax assets have been fully offset by a valuation allowance.

The Company operates in various tax jurisdictions which are subject to audit by various tax authorities. The Company recognizes a tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. The Company recognizes interest and penalties related to unrecognized tax benefits in the income tax provision in the consolidated statements of operations.

Net Loss Per Share Attributable to Common Stockholders

The Company presents net loss per share attributable to common stockholders in conformity with the two-class method required for participating securities. Under the two-class method, net loss is attributed to common stockholders and participating securities based on their participation rights. The Company considers its redeemable convertible preferred stock, early exercised stock options, and unvested restricted stock to be participating securities and contractually entitles the holders of such shares to participate in dividends but does not contractually obligate the holders of such shares to participate in the Company's losses. As such, net losses for the periods presented were not allocated to these securities.

The Company computes basic net loss per share attributable to common stockholders by dividing the net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period, adjusted for outstanding shares that are subject to repurchase. Diluted net loss per share attributable to common stockholders is computed by giving effect to all potentially dilutive securities outstanding for the period. For periods in which the Company reports net losses, diluted net loss per share attributable to common stockholders is the same as basic net loss per share attributable to common stockholders, because all potentially dilutive securities are anti-dilutive.

Stock-Based Compensation

Stock-based compensation expense for stock-based awards granted to employees and non-employees is measured based on the grant date fair value of the awards and recognized in the consolidated statements of operations on a straight-line basis over the period during which services are provided in exchange for the award, generally, the vesting period of the award. The grant date fair value of stock options granted is estimated using the Black-Scholes option pricing model. Forfeitures are accounted for as they occur.

F-32

Segments

The Company has one reportable and operating segment. The Company's chief operating decision maker is its Chief Executive Officer ('CEO'), who reviews financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance, and allocating resources. See Note 14 - Geographical Information for more details on the Company's revenue and long-lived assets by jurisdiction.

Recently Adopted Accounting Pronouncements

In January 2016, the Financial Accounting Standards Board ('FASB') issued Accounting Standard Update ('ASU') 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 amends certain aspects of the recognition, measurement, presentation, and disclosure of financial instruments. The Company adopted this standard as of January 1, 2019, and the adoption did not have a material impact on the Company's consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) ('Topic 842'), which generally requires companies to recognize operating and financing lease liabilities and corresponding ROU assets on the consolidated balance sheets. On January 1, 2019, the Company adopted Topic 842 using the modified retrospective transition approach by applying the new standard to all leases existing at the date of initial application.

Upon adoption of the new standard on January 1, 2019, the Company did not elect the package of practical expedients provided under the guidance, and therefore reassessed whether existing or expired contracts are or contain a lease, the lease classification, and any initial direct costs for any existing leases.

The Company has elected to not separate the lease and non-lease components within the contract. Therefore, all fixed payments associated with the lease are included in the ROU asset and the lease liability. These costs often relate to the payments for a proportionate share of real estate taxes, insurance, common area maintenance, and other operating costs in addition to a base rent. Any variable payments related to the lease will be recorded as lease expense when and as incurred. The Company has elected this practical expedient for its real estate asset class. As an accounting policy election, the Company has also included both lease and non-lease components within the lease expense. The Company did not elect the hindsight practical expedient.

Adoption of the new standard resulted in operating lease ROU assets of $5.4 million and operating lease liabilities of $5.4 million, of which $2.8 million was recorded in operating lease liabilities, current and $2.6 million in operating lease liabilities, non-current on the consolidated balance sheets as of January 1, 2019. The adoption of the new standard did not have a material impact on the consolidated statements of operations or on the consolidated statements of cash flows.

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The Company adopted this standard as of January 1, 2019, and the adoption did not have a material impact on the Company's consolidated financial statements.

In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which allows companies to reclassify stranded tax effects resulting from the 2017 Tax Cuts and Jobs Act ('Tax Act'), from accumulated other comprehensive income to retained earnings. The Company adopted this standard as of January 1, 2019, and the adoption did not have a material impact on the Company's consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 changes the disclosure requirements for fair value measurement. The Company adopted this standard as of January 1, 2020, and the adoption did not have a material impact on the Company's consolidated financial statements.

Recently Issued Accounting Pronouncements Not Yet Adopted

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses(Topic 326): Measurement of Credit Losses on Financial Instruments, and has since issued various amendments including ASU 2018-19, ASU 2019-04, and ASU 2019-05. The guidance and related amendments modify the accounting for credit losses for most financial assets and require the use of an expected loss model, replacing the currently used incurred loss method. Under this model, entities will be required to estimate the lifetime expected credit loss on such instruments and record an allowance to offset the amortized cost basis of the financial asset, resulting in a net presentation of the amount expected to be collected on the financial asset. The new guidance will be effective for the Company beginning January 1, 2023, though early adoption is permitted. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

In December 2019, the FASB issued ASU 2019-12, Income Taxes - Topic 740 - Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principals in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The ASU is effective for fiscal years beginning after December 15, 2021, with early adoption permitted. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

Note 3. Acquisitions

Pixel Labs, Inc. Business Combination

On August 22, 2019 the Company executed a merger agreement to acquire the assets and liabilities of Pixel Labs, Inc. ('Pixel Labs'). The acquisition closed on August 27, 2019. Pixel Labs is a media technology company. The Company acquired Pixel Labs primarily for its ability to power hyperlocal content creation using machine learning and data science. The acquisition date fair value of the aggregate purchase consideration was $7.6 million, of which $5.2 million was paid in cash, $1.5 million was comprised of 165,152 shares of common stock, and a time-based cash and share holdback of $0.7 million and $0.2 million, respectively, to be paid at a future date. The cash and share holdback of $0.9 million was included within accrued expenses and other current liabilities as of December 31, 2019. In November 2020 final settlement of the holdback was completed.

At closing, certain Pixel Labs stockholders had not completed administrative forms that were required for the Company's common stock to be legally issued. There were 501,631 shares legally issuable related to the acquisition of which the Company issued 426,316 shares during the year ended December 31, 2019 related to the acquisition. Of the total 426,316 shares issued, 304,992 shares were related to Founder Shares (granted to the founder of Pixel Labs), which were not included within the purchase consideration as they were considered payment for a post-combination expense and were accounted for as post-combination compensation cost. The Company included the total fair value of the consideration for the 165,152 shares legally issued and legally issuable within additional-paid-in capital and common stock as of December 31, 2019. During the six months ended June 30, 2021 and year ended December 31, 2020 an additional 6,725 and 9,552 shares, respectively, were issued as a result of the administrative forms being completed. In April 2020 the founder of Pixel Labs departed, and therefore the unvested Founder Shares were cancelled as Founder Shares were contingent upon continued employment.

The acquisition was accounted for as a business combination, and the total purchase price was allocated to the net tangible and intangible assets and liabilities acquired based on their respective fair values on the acquisition date and the excess was recorded as goodwill. Pixel Labs' historical financial results did not have a material impact on the Company's consolidated financial statements and therefore pro forma disclosures have not been presented.

F-34

The assets acquired and liabilities assumed in connection with the acquisition were recorded at their fair value on the date of acquisition as follows (in thousands):


Cash and cash equivalents	$	20
Accounts receivable	64
Prepaid expenses and other current assets	87
Capitalized internal-use software costs (recorded in property and equipment)	897
Goodwill	1,211
Intangible assets, net	5,630
Accrued expenses and other current liabilities	(286)
Total purchase consideration	$	7,623

Intangible assets acquired included developed technology with an estimated useful life of 5 years and customer relationships and trade names with estimated useful lives of 2 years. The fair value assigned to the developed technology was determined primarily using the replacement cost approach, which estimates the cost to reproduce the asset. The Company will amortize the fair value of these intangible assets on a straight-line basis over their respective estimated useful lives. Goodwill represents the future economic benefits arising from other assets that could not be individually identified and separately recognized, such as the acquired assembled workforce of Pixel Labs. In addition, goodwill represents the future benefits as a result of the acquisition that will enhance the Company's product available to both new and existing customers and increase the Company's competitive position. The goodwill is not deductible for tax purposes.

The Company incurred acquisition-related expenses of $0.6 million which were recorded in general and administrative expenses in the consolidated statements of operations.

Total	$	4,747

Legal matters

From time to time, the Company is a party to a variety of claims, lawsuits, and proceedings which arise in the ordinary course of business, including claims of alleged infringement of intellectual property rights. The Company records a liability when it believes that it is probable that a loss will be incurred and the amount of loss or range of loss can be reasonably estimated. The Company discloses potential losses when they are reasonably possible. In the Company's opinion, resolution of pending matters is not likely to have a material adverse impact on its consolidated results of operations, cash flows, or its financial position. Given the unpredictable nature of legal proceedings, the Company bases its estimate on the information available at the time of the assessment. As additional information becomes available, the Company reassesses the potential liability and may revise the estimate. There were no such material matters as of June 30, 2021 (unaudited) and December 31, 2020 and 2019.

Indemnification

In the ordinary course of business, the Company often includes standard indemnification provisions in its arrangements with its customers, partners, suppliers, and vendors. Pursuant to these provisions, the Company may be obligated to indemnify such parties for losses or claims suffered or incurred in connection with its service, breach of representations or covenants, intellectual property infringement, or other claims made against such parties. These provisions may limit the time within which an indemnification claim can be made. It is not possible to determine the maximum potential amount under these indemnification obligations due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. For the six months ended June 30, 2021 and 2020 (unaudited) and the years ended December 31, 2020 and 2019 the Company did not incur material costs to defend lawsuits or settle claims related to these indemnifications. The Company believes the fair value of these liabilities is not material and accordingly has no liabilities recorded for these agreements as of June 30, 2021 (unaudited) and December 31, 2020 and 2019.

Note 9. Redeemable Convertible Preferred Stock

During the year ended December 31, 2019, the Company issued 8,339,262 shares of Series H redeemable convertible preferred stock for gross cash proceeds of $170.0 million, less issuance costs of $0.2 million. All Series H redeemable convertible preferred stock was issued at a purchase price of $20.3855 per share.

The Company's redeemable convertible preferred stock as of June 30, 2021 (unaudited) and December 31, 2020 and 2019 consisted of the following (in thousands, except for per share data):


Redeemable Convertible Preferred Stock Authorized	Redeemable Convertible Preferred Stock Issued and Outstanding	Issuance Price Per Share	Carrying Value	Aggregate Liquidation Preference

61,332	61,332	$	447,166	$	447,890

The holders of redeemable convertible preferred stock have various rights and preferences, as follows:

Contingent Redemption Rights- The holders of redeemable convertible preferred stock have no voluntary rights to redeem shares. A merger or consolidation of the Company into another entity, a liquidation or winding up of the Company, a greater than 50% change in control, or a sale of substantially all of its assets would constitute a redemption event. Although the redeemable convertible preferred stock is not mandatorily or currently redeemable, a liquidation or winding up of the Company would constitute a redemption event outside its control. Therefore, all shares of redeemable convertible preferred stock have been presented outside of permanent equity on the consolidated balance sheets. The carrying values of redeemable convertible preferred stock have not been accreted to their redemption values as redemption events are not considered probable of occurrence.

Voting Rights- The holder of each share of redeemable convertible preferred stock has the right to one vote for each share of common stock into which such holder's share of redeemable convertible preferred stock could then be converted with the full voting rights and powers equal to the voting rights and powers of the holders of the common stock.

Dividends- The holders of Series A, B, C, D, E, F, G, and H redeemable convertible preferred stock shall be entitled to receive non-cumulative dividends of $0.04, $0.05035, $0.2052, $0.2551, $0.7075, $1.16020, $1.4875, and $1.6308 per share, respectively, if and when declared by the Board of Directors out of funds available in preference and priority to any payment of dividends to common stockholders. After payment of such dividends, any additional dividends are distributed among the holders of redeemable convertible preferred stock and common stock pro rata on an if-converted basis. As of June 30, 2021 (unaudited) and December 31, 2020, the Company had declared no dividends to date.

Liquidation Preference- In the event of any liquidation, dissolution, or winding up of the Company, whether voluntary or involuntary, the holders of Series A, B, C, D, E, F, G, and H redeemable convertible preferred stock, prior to preference to any distribution to the holders of common stock, are entitled to be paid a per share liquidation preference of $0.50, $0.62955, $2.565, $3.1888, $8.8437, $14.5027, $18.5936, and $20.3855, respectively. A sale of substantially all of the Company's assets or a change in control is treated as a deemed liquidation. After full payment to the holders of the redeemable convertible preferred stock of their respective liquidation preference, the remaining

F-42

assets of the Company legally available for distribution to stockholders shall be distributed on a pro-rata basis to the holders of common stock.

Conversion Rights- Each share of redeemable convertible preferred stock shall be convertible at the option of the holder thereof, at any time after the date of issuance of such share, at the office of the Company or any transfer agent for such stock, into such number of fully paid and non-assessable shares of common stock as is determined by dividing the applicable original issuance price for such series by the applicable conversion price. As of June 30, 2021 (unaudited) and December 31, 2020 and 2019, the conversion price for each share of redeemable convertible preferred stock was the original issuance price such that each share would convert into common stock at a one-for-one rate.

Each share of Series A through H redeemable convertible preferred stock shall automatically be converted into shares of common stock at the then effective conversion price for such share upon the earlier of: (i) the date specified by vote or written consent or agreement of holders of at least a majority of the shares of such preferred stock then outstanding, and (ii) upon the closing of the sale of the Company's common stock in a firm commitment, underwritten public offering registered under the Securities Act of 1933, ('the Act'), as amended other than a registration relating solely to a transaction under Rule 145 under the Act (or any successor thereto) or to an employee benefit plan of the Company, with aggregate gross proceeds to the Company (prior to underwriters' discounts and commissions) that exceeds $50,000,000 (a 'Qualified IPO').

Certain stock option grant agreements permit exercise prior to vesting. Upon termination of service of an employee, the Company has the right to repurchase any unvested, but issued, common stock at the original purchase price. The consideration received for an exercise of an option is accounted for as a deposit of the exercise price and is recorded as a liability. Upon vesting of the shares pursuant to the grant agreements, the shares and related liability are reclassified into stockholder's deficit. As of June 30, 2021 (unaudited) and December 31, 2020 and 2019, the Company had $0.9 million, $1.1 million, and $1.7 million recorded in accrued expenses and other current liabilities related to 182,579, 223,136, and 324,500 unvested shares of common stock subject to repurchase, respectively.

Restricted Stock Subject to Repurchase

In 2018, an executive of the Company purchased 4,961,279 shares of restricted stock, subject to time-based service requirements, which vest over a forty-eight month period. The shares issued upon the purchase of restricted stock are considered to be legally issued and outstanding on the date of purchase and the executive has full voting rights. Upon termination of service, the Company may repurchase unvested shares acquired at a price equal to the price per share paid upon the exercise. Upon vesting of the shares pursuant to the grant agreements, the shares and related liability are reclassified into stockholder's deficit. As of June 30, 2021 (unaudited), the Company had $7.6 million recorded in deposits related to 1,653,760 unvested shares of common stock subject to repurchase. As of

F-43

December 31, 2020, the Company had $10.5 million recorded in deposits related to 2,273,919 unvested shares of common stock subject to repurchase. As of December 31, 2019, the Company had $16.2 million recorded in deposits related to 3,514,239 unvested shares of common stock subject to repurchase. For the six months ended June 30, 2021 and 2020 (unaudited) and for the years ended December 31, 2020 and 2019, the Company recorded stock-based compensation expense of $2.3 million, $2.3 million, $4.6 million, and $4.6 million, respectively, related to this restricted stock.

2008 Stock Option Plan

In 2018, the 2008 Stock Option Plan ('the Plan') was terminated, and the Company's Board of Directors approved the adoption of the 2018 Equity Incentive Plan ('the 2018 Plan'), which includes both incentive and non-statutory stock options. As of June 30, 2021 (unaudited) and December 31, 2020 and 2019, the Company had reserved 3,349,463 shares, 4,043,637 shares, and 7,762,602 shares, respectively, of its common stock under the Plan for future issuance. The Company may grant shares of common stock to employees, directors, and service providers at prices not less than the fair market value at date of grant for incentive stock options and not less than 85% of fair market value for non-qualified stock options. Options granted to a person who, at the time of the grant, owns more than 10% of the voting power of all classes of stock shall be at no less than 110% of the fair market value and expire five years from the date of grant. All other options generally have a contractual term of ten years. Options generally vest over four years.

A summary of the Company's stock option activity under the Plan and related information was as follows (in thousands, except per share data):


Number of Options	Weighted- Average Exercise Price	Weighted Average Remaining Contractual Term (years)	Aggregate Intrinsic Value
Balances at December 31, 2019	13,596	$	4.47	7.8	$	39,266

Balances at June 30, 2021 (unaudited)	19,525	$	6.49	8.5	$	283,428
Options vested and exercisable at December 31, 2020	6,274	$	3.89	6.0	$	22,405
Options vested and exercisable at June 30, 2021 (unaudited)	6,065	$	4.70	6.3	$	98,930

The intrinsic value is calculated as the difference between the exercise price of the underlying common stock option award and the estimated fair value of the Company's common stock. The weighted average grant date fair value of options granted was $11.33 per share, $8.96 per share, $7.44 per share, and $6.71 per share during the six months ended June 30, 2021 and 2020 (unaudited) and the years ended December 31, 2020 and 2019, respectively.

The total number of shares vested during the six months ended June 30, 2021 and 2020 (unaudited) and during the years ended December 31, 2020 and 2019 was 2,513,546, 1,903,007, 4,189,825, and 2,960,091, respectively. The weighted average grant-date fair value of options vested was $5.99 per share, $4.65 per share, $5.08 per share, and $3.70 per share during the six months ended June 30, 2021 and 2020 (unaudited) and the years ended December 31, 2020 and 2019, respectively. The intrinsic value of the options exercised was $8.9 million, $5.2 million, $9.8 million, and $4.4 million for the six months ended June 30, 2021 and 2020 (unaudited) and for the years ended December 31, 2020 and 2019, respectively.

F-44

The Company granted 6,324 options to non-employees during the six months ended June 30, 2021 (unaudited). The Company did not issue any grants to non-employees during the years ended December 31, 2020 and 2019.

The table above includes 743,184 options granted to the Company's Chief Executive Officer during the six months ended June 30, 2021 which are subject to a performance-based vesting condition that will be satisfied in full upon the first to occur of: (i) a Qualified IPO, (ii) a direct listing, or (iii) the closing by the Company of a transaction with a publicly traded special purpose acquisition company ('SPAC') in which the common stock is publicly listed on a securities exchange. The options will vest in a single installment upon the satisfaction of the performance-based vesting condition subject to the Chief Executive Officer's continuous employment through such date. As the performance-based vesting condition of these options is not deemed probable until consummated, no stock-based compensation expense is recorded related to these options until the performance-based vesting condition becomes probable of occurring. If the performance-based vesting condition had been satisfied on June 30, 2021, the Company would have recognized stock-based compensation expense of $8.5 million (unaudited) and would have no unrecognized stock-based compensation expense related to these options as of June 30, 2021 (unaudited).

Valuation Assumptions

The Company's use of the Black-Scholes option-pricing model to estimate the fair value of stock options granted requires the input of highly subjective assumptions. These assumptions were estimated as follows:

Fair value of the underlying common stock - Because the Company's common stock is not yet publicly traded, the Company must estimate the fair value of common stock. The Board of Directors considers numerous objective and subjective factors to determine the fair value of the Company's common stock including, but not limited to: (i) the results of contemporaneous third-party valuations of the Company's common stock; (ii) the prices, rights, preferences, and privileges of the Company's redeemable convertible preferred stock relative to those of its common stock; (iii) the lack of marketability of the Company's common stock; (iv) actual operating and financial results; (v) current business conditions and projections; (vi) the likelihood of achieving a liquidity event, such as an initial public offering, merger, or acquisition of the Company, given prevailing market conditions; (vii) transactions involving the Company's shares; (viii) the history and nature of its business, industry trends and competitive environment; and (iv) general economic outlook.

Expected volatility - Expected volatility is a measure of the amount by which the stock price is expected to fluctuate, Since the Company does not have sufficient trading history of its common stock, it estimates the expected volatility of its stock options at their grant date by taking the weighted average historical volatility of a group of comparable publicly traded companies over a period equal to the expected term of the options.

Expected term - The Company determines the expected term based on the average period the stock options are expected to remain outstanding using the simplified method, calculated as the midpoint of the stock options' vesting term and contractual expiration period, as the Company does not have sufficient historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior.

Risk-free rate - The Company uses the U.S. Treasury yield for its risk-free interest rate that corresponds with the expected term.

Expected dividend yield - The Company utilizes a dividend yield of zero, as it does not currently issue dividends and does not expect to in the future.

As of June 30, 2021 (unaudited), there was $124.7 million of unrecognized stock-based compensation expense, which is expected to be recognized over a weighted average period of 2.6 years. As of December 31, 2020, there was $65.2 million of unrecognized stock-based compensation expense, which is expected to be recognized over a weighted average period of 2.6 years.

Based upon available objective evidence, management believes it is more likely than not that the U.S. net deferred tax assets will not be fully realizable. Accordingly, the Company has established a full valuation allowance for its U.S. net deferred tax assets. The valuation allowance increased by $8.7 million and $21.5 million, respectively, during 2020 and 2019. The Company had aggregate deferred tax assets of $105.8 million and $89.3 million as of December 31, 2020 and 2019, respectively.

As of December 31, 2020, the Company had federal net operating loss carryforwards of $331.9 million, which begin to expire in 2028, and state net operating loss carryforwards of $185.0 million, which begin to expire in 2028. Of the $331.9 million U.S. federal net operating losses $152.8 million is carried forward indefinitely but is limited to 80% of taxable income. As of December 31, 2020, the Company had federal tax credits of $12.3 million, which begin to expire in 2028, and state tax credits of $10.1 million, which do not expire. The Internal Revenue Code ('IRC') limits the amount of net operating loss carryforwards that a company may use in a given year in the event of certain cumulative changes in ownership over a three-year period as described in Section 382 of the IRC. Utilization of net operating loss carryforwards and credits may be subject to a substantial annual limitation due to the ownership change limitations provided by the IRC, as amended, and similar state provisions. The annual limitation may result in the expiration of net operating losses and credits before utilization.

F-48

The Company accounts for uncertainty in income taxes in accordance with ASC 740 Income Taxes. Tax positions are evaluated in a two-step process, whereby the Company first determines whether it is more likely than not that a tax position will be sustained upon examination by the tax authority, including resolutions of any related appeals or litigation processes, based on technical merit. If a tax position meets the more-likely-than-not recognition threshold it is then measured to determine the amount of benefit to recognize in the financial statements. The tax position is measured as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement.

A reconciliation of the beginning and ending balances of unrecognized tax benefit were as follows (in thousands):


Years Ended December 31,
2020	2019
Gross unrecognized tax benefits - beginning of year	$	6,971	$	4,647
Increases related to current year tax positions	3,129	1,939
Increases related to prior year tax positions	43	386
Gross unrecognized tax benefits - end of year	$	10,143	$	6,972

All of the unrecognized tax benefits as of December 31, 2020 are accounted for as a reduction in the Company's deferred tax assets. Due to the Company's valuation allowance, none of the $10.1 million of unrecognized tax benefits, related solely to its federal and state research and development income tax credits, would affect the Company's effective tax rate, if recognized. The Company does not believe it is reasonably possible that its unrecognized tax benefits will significantly change in the next twelve months.

The Company recognizes interest and penalties related to unrecognized tax benefits as income tax expense. There was no interest or penalties accrued related to unrecognized tax benefits for the years ended December 31, 2020 and 2019, and no liability for accrued interest or penalties related to unrecognized tax benefits as of December 31, 2020 and 2019.

The Company has identified its U.S. federal and California tax returns as 'material' tax filings. The Company is not currently under examination by income tax authorities in any jurisdiction. However, because the Company has net operating losses in several jurisdictions, including the United States federal and various state jurisdictions, certain items attributable to closed tax years are still subject to adjustment by applicable taxing authorities through an adjustment to tax attributes carried forward to open years. All tax returns will remain open for examination by the federal and most state taxing authorities for three years and four years, respectively, from the date of utilization of any net operating loss carryforwards or research and development income tax credits.

For the six months ended June 30, 2021 and 2020 (unaudited)

The Company's provision for income taxes for interim periods was determined using an estimate of its annual effective tax rate, adjusted for discrete items, if any, that arose during the period. Each quarter, the Company updates its estimate of the annual effective tax rate, and if the estimated annual effective tax rate changes, the Company makes a cumulative adjustment in such period.

The Company's quarterly tax provision, and estimate of its annual effective tax rate, is subject to variation due to several factors, including variability in pretax income (or loss), the mix of jurisdictions to which such income (or loss) relates, tax law developments and changes in how the Company does business, such as acquisitions, intercompany transactions, or the Company's corporate structure.

The Company recorded an income tax expense for the six months ended June 30, 2021 and 2020, neither of which were material and both were primarily driven by foreign taxes.

resolutions adopted by the Board providing for the issuance of such series and included in a certificate of designation (a 'Preferred Stock Designation') filed pursuant to the DGCL, and the Board is hereby expressly vested with the authority to the full extent provided by law, now or hereafter, to adopt any such resolution or resolutions.

Section 4.3. Common Stock.

(a) Voting.

(i) Except as otherwise required by law or this Certificate (including any Preferred Stock Designation), the holders of the Common Stock shall exclusively possess all voting power with respect to the Corporation.

(ii) Except as otherwise required by law or this Certificate (including any Preferred Stock Designation), on each matter properly submitted to the stockholders on which the holders of the Common Stock are entitled to vote: (1) the holders of shares of Class A Common Stock shall be entitled to one vote for each such share and (2) the holders of shares of Class B Common Stock shall be entitled to the number of votes for each such share equal to the number of shares (including fractional shares) of Class A Common Stock into which such share of Class B Common Stock held by such holder would be convertible if converted as of the record date for determining stockholders entitled to vote on such matter.

(iv) Notwithstanding the foregoing, except as otherwise required by law or this Certificate (including any Preferred Stock Designation), holders of shares of any series of Common Stock shall not be entitled to vote on any amendment to this Certificate (including any amendment to any Preferred Stock Designation) that relates solely to the terms of one or more outstanding series of Preferred Stock or other series of Common Stock if the holders of such affected series of Preferred Stock or Common Stock, as applicable, are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to this Certificate (including any Preferred Stock Designation) or the DGCL.

(b) Class B Common Stock.

(i) Conversion. All issued and outstanding shares of Class B Common Stock shall, immediately after the closing of the initial Business Combination, automatically convert into an aggregate number of shares of Class A Common Stock equal to (A) the quotient of (i) the Outstanding Shares divided by (ii) one minus the Applicable Percentage, minus (B) the Outstanding Shares. Each share of Class B Common Stock shall convert into its pro rata number of shares of Class A Common Stock pursuant to this Section 4.3(b). The pro rata share for each holder of Class B Common Stock will be determined as follows: Each share of Class B Common Stock shall convert into such number of shares of Class A Common Stock as is equal to a fraction, the numerator of which shall be the total number of shares of Class A Common Stock into which all of the issued and outstanding shares of Class B Common Stock shall be converted pursuant to this Section 4.3(b) and the denominator of which shall be the total number of issued and outstanding shares of Class B Common Stock at the time of conversion.

Any action required or permitted to be taken at any meeting of the holders of Class B Common Stock may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, shall be signed by the holders of the outstanding Class B Common Stock having not less than the minimum number of votes that would be necessary to authorize or take such

Annex B-ii

action at a meeting at which all shares of Class B Common Stock were present and voted and shall be delivered to the Corporation by delivery to its registered office in the State of Delaware, its principal place of business, or an officer or agent of the Corporation having custody of the book in which minutes of proceedings of stockholders are recorded. Delivery made to the Corporation's registered office shall be by hand or by certified or registered mail, return receipt requested. Prompt written notice of the taking of corporate action without a meeting by less than unanimous written consent of the holders of Class B Common Stock shall, to the extent required by law, be given to those holders of Class B Common Stock who have not consented in writing and who, if the action had been taken at a meeting, would have been entitled to notice of the meeting if the record date for notice of such meeting had been the date that written consents signed by a sufficient number of holders of Class B Common Stock to take the action were delivered to the Corporation.

(i) Conversion Upon Trading Triggers.

(1) One-third of all issued and outstanding shares of Class K Common Stock as of the First Price Vesting shall automatically convert into the First Price Vesting Conversion Shares on the day following the First Price Vesting.

(2) One-third of all issued and outstanding shares of Class K Common Stock as of the Second Price Vesting shall automatically convert into the Second Price Vesting Conversion Shares on the day following the Second Price Vesting.

(1) if (and only if) the First Price Vesting shall not have occurred prior to or in connection with such Strategic Transaction and such Strategic Transaction results in the holders of Class A Common Stock having the right to exchange their shares of Class A Common Stock for cash, securities or other property at an effective price greater than $15.00 per share of Class A Common Stock and less than or equal to $20.00 per share of Class A Common Stock (each as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like), all of the then outstanding shares of Class K Common Stock will convert into a number of Class A Common Stock equal to the First Price Vesting Conversion Shares, provided, however that in calculating the First Price Vesting Conversion Shares the Applicable Percentage shall be an amount equal to (i) the original Applicable Percentage minus (ii) the product of (a) 5% multiplied by (b) a fraction, the numerator of which is equal to $20.00 minus the effective price per share of Class A Common Stock of the Strategic Transaction and the denominator of which is $5.00 (each as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like);

(2) if (and only if) the Third Price Vesting shall not have occurred prior to or in connection with such Strategic Transaction and such Strategic Transaction results in the holders of Class A Common Stock having the right to exchange their shares of Class A Common Stock for cash, securities or other property at an effective price greater than $25.00 per share of Class A Common Stock and less than or equal to $30.00 per share of Class A Common Stock (each as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like), then, (i) the First Price Vesting and Second Price Vesting shall automatically be satisfied (to the extent either had not already been satisfied) and (ii) all of the then remaining outstanding shares of Class K Common Stock (after giving effect to the First Price Vesting or Second Price Vesting that shall have occurred prior to or in connection with such Strategic Transaction) will convert into a number of Class A Common Stock equal to the Third Price Vesting Conversion Shares, provided, however that in calculating the Third Price Vesting Conversion Shares the Applicable Percentage shall be an amount equal to the (i) original Applicable Percentage minus (ii) the product of (a) 5% multiplied by (b) a fraction, the numerator of which is equal to $30.00 minus the effective price per share of Class A Common Stock of the Strategic Transaction and the denominator of which is $5.00 (each as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like); and

(3) if (and only if) the Third Price Vesting shall not have occurred prior to or in connection with such Strategic Transaction and such Strategic Transaction results in the holders of Class A Common Stock having the right to exchange their shares of Class A Common Stock for cash, securities or other property at an effective price greater than $30.00 per share of Class A Common Stock (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like), then each of the First Price Vesting, Second Price Vesting and Third Price Vesting shall automatically be satisfied (to the extent any had not already been satisfied).

(iv) Pro Rata Conversion. Each share of Class K Common Stock that is converting pursuant to this Section 4.3(c) shall convert into its pro rata number of shares of Class A Common Stock that is converting pursuant to this Section 4.3(c) based on the proportion of the number of shares of Class K Common Stock that are then converting by the number of shares of Class A Common Stock issuable upon such conversion.

(v) Forfeiture. Each share of Class K Common Stock that remains issued and outstanding as of the 10th anniversary of the Corporation's initial Business Combination shall be forfeited by the holder who holds such share Class K Common Stock for no consideration.

Except for the withdrawal of interest to pay franchise and income taxes as well as expenses relating to the administration of the Trust Account, none of the funds held in the Trust Account (including the interest earned on the funds held in the Trust Account) will be released from the Trust Account until the earliest to occur of (i) the completion of the initial Business Combination, (ii) the redemption of 100% of the Offering Shares (as defined below) if the Corporation is unable to complete its initial Business Combination within 24 months from the closing of the Offering, or 27 if the Corporation and a third-party shall have executed a letter of intent, agreement in principle or definitive agreement for an initial Business Combination within 24 months from the closing of this Offering or (iii) the redemption of shares in connection with a vote seeking to amend any provisions of this Certificate relating to stockholders' rights or pre-initial Business Combination activity (as described in Section 7.7). Holders of shares of the Common Stock

Annex B-viii

sold in the Offering (the 'Offering Shares') (whether such Offering Shares were purchased in the Offering or in the secondary market following the Offering and whether or not such holders are Khosla Ventures SPAC Sponsor II LLC (the 'Sponsor') or officers or directors of the Corporation, or affiliates of any of the foregoing) are referred to herein as 'Public Stockholders.'

Section 7.2. Redemption Rights.

(a) Prior to the consummation of the initial Business Combination, the Corporation shall provide all holders of Offering Shares with the opportunity to have their Offering Shares redeemed, out of the funds legally available therefor, upon the consummation of the initial Business Combination pursuant to, and subject to the limitations of, Section 7.2(b) and Section 7.2(c) (such rights of such holders to have their Offering Shares redeemed pursuant to such Sections, the 'Redemption Rights') for cash equal to the applicable redemption price per share determined in accordance with Section 7.2(b) (the 'Redemption Price'); provided, however, that the Corporation shall not redeem or repurchase Offering Shares to the extent that such redemption would result in the Corporation's failure to have net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) of the Exchange Act) in excess of $5,000,001 or any greater net tangible asset or cash requirement upon consummation of the Corporation's initial Business Combination which may be contained in the agreement relating to the initial Business Combination (such limitation hereinafter called the 'Redemption Limitation'). Notwithstanding anything to the contrary contained in this Certificate, there shall be no Redemption Rights or liquidating distributions with respect to any warrant issued pursuant to the Offering.

(b) If the Corporation offers to redeem the Offering Shares other than in conjunction with a stockholder vote on an initial Business Combination with a proxy solicitation pursuant to Regulation 14A of the Exchange Act (or any successor rules or regulations) and filing proxy materials with the SEC, the Corporation shall offer to redeem the Offering Shares upon the consummation of the initial Business Combination, subject to lawfully available funds therefor, in accordance with the provisions of Section 7.2(a) pursuant to a tender offer in accordance with Rule 13e-4 and Regulation 14E of the Exchange Act (or any successor rule or regulation) (such rules and regulations hereinafter called the 'Tender Offer Rules'), which it shall commence prior to the consummation of the initial Business Combination and shall file tender offer documents with the SEC prior to the consummation of the initial Business Combination that contain substantially the same financial and other information about the initial Business Combination and the Redemption Rights as is required under Regulation 14A of the Exchange Act (or any successor rule or regulation) (such rules and regulations hereinafter called the 'Proxy Solicitation Rules'), even if such information is not required under the Tender Offer Rules; provided, however, that if a stockholder vote is required by law to approve the proposed initial Business Combination, or the Corporation decides to submit the proposed initial Business Combination to the stockholders for their approval for business or other legal reasons, the Corporation shall offer to redeem the Offering Shares, subject to lawfully available funds therefor, in accordance with the provisions of Section 7.2(a) in conjunction with a proxy solicitation pursuant to the Proxy Solicitation Rules (and not the Tender Offer Rules) at a price per share equal to the Redemption Price calculated in accordance with the following provisions of this Section 7.2(b). In the event that the Corporation offers to redeem the Offering Shares pursuant to a tender offer in accordance with the Tender Offer Rules, the Redemption Price per share of the Common Stock payable to holders of the Offering Shares tendering their Offering Shares pursuant to such tender offer shall be equal to the quotient obtained by dividing: (i) the aggregate amount on deposit in the Trust Account as of two business days prior to the consummation of the initial Business Combination, including interest not previously released to the Corporation to pay its franchise and income taxes as well as expenses relating to the administration of the Trust Account, by (ii) the total number of then outstanding Offering Shares.

In no other circumstances shall a Public Stockholder have any right or interest of any kind in or to distributions from the Trust Account, and no stockholder other than a Public Stockholder shall have any interest in or to the Trust Account.

(b) Each Public Stockholder that does not exercise its Redemption Rights shall retain its interest in the Corporation and shall be deemed to have given its consent to the release of the remaining funds in the Trust Account to the Corporation, and following payment to any Public Stockholders exercising their Redemption Rights, the remaining funds in the Trust Account shall be released to the Corporation.

(c) The exercise by a Public Stockholder of the Redemption Rights shall be conditioned on such Public Stockholder following the specific procedures for redemptions set forth by the Corporation in any applicable tender offer or proxy materials sent to the Public Stockholders relating to the proposed initial Business Combination. Payment of the amounts necessary to satisfy the Redemption Rights properly exercised shall be made as promptly as practical after the consummation of the initial Business Combination.

The Corporation's ability to provide such opportunity is subject to the Redemption Limitation.

Section 7.8. Minimum Value of Target. The Corporation's initial Business Combination must occur with one or more target businesses that together have a fair market value of at least 80% of the assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on the income earned on the Trust Account) at the time of the agreement to enter into the initial Business Combination.

3.2. Voting Rights.Except as otherwise expressly provided by this Restated Certificate of Incorporation or as required by law, the holders of shares of Class A Common Stock and Class B Common Stock shall (i) at all times vote together as a single class and not as separate series or classes on all matters (including the election of directors) submitted to a vote of the stockholders of the Corporation, (ii) be entitled to notice of any stockholders' meeting in accordance with the Bylaws of the Corporation (as the same may be amended and/or restated from time to time, the 'Bylaws') and (iii) be entitled to vote upon such matters and in such manner as may be provided by applicable law; provided, however, that, except as otherwise required by law or this Restated Certificate of Incorporation, holders of shares of Class A Common Stock and Class B Common Stock shall not be entitled to vote on any amendment to this Restated Certificate of Incorporation (including any Certificate of Designation relating to any series of Preferred Stock) that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together as a class with the holders of one or more other such series, to vote thereon pursuant to this Restated Certificate of Incorporation (including any Certificate of Designation relating to any series of Preferred Stock).

Annex C-ii

available therefor; provided, however, that in the event a dividend is paid in the form of shares of Class A Common Stock or Class B Common Stock (or rights to acquire such shares), then holders of Class A Common Stock shall receive shares of Class A Common Stock (or rights to acquire such shares, as the case may be) and holders of Class B Common Stock shall receive shares of Class B Common Stock (or rights to acquire such shares, as the case may be), with holders of shares of Class A Common Stock and Class B Common Stock receiving, on a per share basis, an identical number of shares of Class A Common Stock or Class B Common Stock, as applicable. Notwithstanding the foregoing, the Board of Directors may pay or make a disparate dividend or distribution per share of Class A Common Stock or Class B Common Stock (whether in the amount of such dividend or distribution payable per share, the form in which such dividend or distribution is payable, the timing of the payment, or otherwise) if (i) such disparate dividend or distribution is approved in advance by the affirmative vote of the holders of a majority of the then-outstanding shares of Class A Common Stock and Class B Common Stock, each voting separately as a class or (ii) such disparate dividend or distribution is paid in the form of securities (or the right to receive securities) of another entity, and (A) the holders of Class A Common Stock receive securities entitling the holder thereof to cast one vote per security (or the right to receive such securities, as applicable) and (B) the holders of Class B Common Stock receive securities entitling the holder thereof to cast ten (10) votes per security (or the right to receive such securities, as applicable).

3.5. Liquidation, Dissolution or Winding Up.Subject to the preferential or other rights of any holders of Preferred Stock then outstanding, upon the liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, holders of Class A Common Stock and Class B Common Stock will be entitled to receive ratably, on a per share basis, all assets of the Corporation available for distribution to its stockholders unless disparate or different treatment of the shares of each such class with respect to distributions upon any such liquidation, dissolution or winding up is approved in advance by the affirmative vote of the holders of a majority of the then-outstanding shares of Class A Common Stock and Class B Common Stock, each voting separately as a class; provided, that for the avoidance of doubt, consideration to be paid or received by a holder of Common Stock pursuant to any employment, consulting, severance or similar services arrangement shall not be deemed to be assets of the Corporation available for distribution to its stockholders for the purpose of this Section 3.5.

3.6. Merger or Consolidation.In the case of any distribution or payment made or other consideration paid in respect, or upon conversion or exchange, of the shares of Class A Common Stock or Class B Common Stock upon the merger or consolidation of the Corporation with or into any other entity, or in the case of any other transaction having an effect on stockholders substantially similar to that resulting from a merger or consolidation, such distribution or payment shall be made, or other consideration shall be paid, ratably on a per share basis among the holders of the Class A Common Stock and Class B Common Stock as a single class; provided, however, that shares of one such class may receive different or disproportionate distributions, payments, or other consideration in connection with such merger, consolidation or other transaction if (i) the only difference in the per share distribution, payment, or other consideration to the holders of the Class A Common Stock and Class B Common Stock is that any securities that a holder of a share of Class B Common Stock receives as part of such merger, consolidation or other transaction upon conversion or in exchange for such holder's Class B Common Stock shall have ten (10) times the voting power of any securities that a holder of a share of Class A Common Stock receives as part of such merger, consolidation or other transaction upon conversion or in exchange for such holder's Class A Common Stock, or (ii) such merger, consolidation or other transaction is approved by the affirmative vote of the holders of a majority of the then-outstanding shares of Class A Common Stock and Class B Common Stock, each voting separately as a class; provided, further, that for the avoidance of doubt, consideration to be paid or received

ARTICLE V: CLASS B COMMON STOCK CONVERSION

1. Optional Conversion.Each share of Class B Common Stock shall be convertible into one (1) fully paid and nonassessable share of Class A Common Stock at the option of the holder thereof at any time upon written notice to the Corporation. Before any holder of Class B Common Stock shall be entitled to convert any of such holder's shares of such Class B Common Stock into shares of Class A Common Stock, such holder shall deliver an instruction, duly signed and authenticated in accordance with any procedures set forth in the Bylaws or any policies of the Corporation then in effect (which will be available upon request therefor made to the Secretary), at the principal corporate office of the Corporation or of any transfer agent for the Class B Common Stock, and shall give written notice to the Corporation at its principal corporate office of such holder's election to convert the same and shall state therein the name or names in which the shares of Class A Common Stock issuable on conversion thereof are to be registered on the books of the Corporation. The Corporation shall, as soon as practicable thereafter, register on the Corporation's books ownership of the number of shares of Class A Common Stock to which such record holder of Class B Common Stock, or to which the nominee or nominees of such record holder, shall be entitled as aforesaid. Such conversion shall be deemed to have occurred immediately prior to the close of business on the date such notice of the election to convert is received by the Corporation, and the person or persons entitled to receive the shares of Class A Common Stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such shares of Class A Common Stock as of such date. The Corporation shall not be required to register a conversion of a share of Class B Common Stock pursuant to this Section 1 of Article V unless it is permitted to do so by law.

2. Automatic Conversion.Each share of Class B Common Stock shall automatically, without further action by the Corporation or the holder thereof, be converted into one (1) fully paid and nonassessable share of Class A Common Stock immediately prior to the close of business on the earlier of (i) ten (10) years from the Closing Date (as defined below) and (ii) the date specified by the affirmative vote of the holders of Class B Common Stock representing not less than two-thirds (2/3) of the voting power of the outstanding shares of Class B Common Stock, voting separately as a single class (each of the events referred to in (i) through (ii) are referred to herein as an 'Automatic Conversion'). The Corporation shall provide notice of an Automatic Conversion of shares of Class B Common Stock pursuant to this Section 2 of Article V to record holders of such shares of Class B Common Stock as soon as practicable following the Automatic Conversion. Such notice shall be provided by any means then permitted by the General Corporation Law; provided, however, that no failure to give such notice nor any defect therein shall affect the validity of an Automatic Conversion. Upon and after an Automatic Conversion, the person registered on the Corporation's books as the record holder of the shares of Class B Common Stock so converted immediately prior to an Automatic Conversion shall be registered on the Corporation's books as the record holder of the shares of Class A Common Stock issued upon Automatic Conversion of such shares of Class B Common Stock, without further action on the part of the record holder thereof. Immediately upon the effectiveness of an Automatic Conversion, the rights of the holders of the shares of Class B Common Stock, converted pursuant to an Automatic Conversion shall cease, and the holders shall be treated for all purposes as having become the record holder or holders of such shares of Class A Common Stock into which such shares of Class B Common Stock were converted.

3. Conversion on Transfer.Each share of Class B Common Stock shall automatically, without further action by the Corporation or the holder thereof, be converted into one (1) fully paid and nonassessable share of

Annex C-iv

Class A Common Stock, upon the occurrence of a Transfer (as defined below), other than a Permitted Transfer (as defined below), of such share of Class B Common Stock.

4. Policies and Procedures.The Corporation may, from time to time, establish such policies and procedures, not in violation of applicable law or this Restated Certificate of Incorporation or the Bylaws, relating to the conversion of shares of the Class B Common Stock into shares of Class A Common Stock as it may deem necessary or advisable. If the Corporation has reason to believe that a Transfer that is not a Permitted Transfer has occurred, the Corporation may request that the purported transferor furnish affidavits or other evidence to the Corporation as it reasonably deems necessary to determine whether a Transfer that is not a Permitted Transfer has occurred, and if such transferor does not within ten (10) days after the date of such request furnish sufficient (as determined by the Board of Directors (but not a committee thereof)) evidence to the Corporation (in the manner provided in the request) to enable the Corporation to determine that no such Transfer has occurred, any such shares of Class B Common Stock, to the extent not previously converted, shall be automatically converted into shares of Class A Common Stock on a one to one basis, and such conversion shall thereupon be registered on the books and records of the Corporation. In connection with any action of stockholders taken at a meeting, the stock ledger of the Corporation shall be presumptive evidence as to who are the stockholders entitled to vote in person or by proxy at any meeting of stockholders and the classes of shares held by each such stockholder and the number of shares of each class held by such stockholder.

2.2.Each director shall hold office until the annual meeting at which such director's term expires and until such director's successor is duly elected and qualified, or until such director's earlier death, resignation, disqualification or removal. Any director may resign at any time upon notice to the Corporation given in writing or by any electronic transmission.

2.3.No director may be removed from the Board of Directors except for cause and only by the affirmative vote of the holders of at least two-thirds (2/3) of the voting power of all of the then-outstanding shares of capital stock of the Corporation entitled to vote generally in the election of directors, voting together as a single class.

2.4.The total number of directors constituting the Whole Board shall be fixed from time to time exclusively by resolution adopted by a majority of the Whole Board. No decrease in the number of directors constituting the Board of Directors shall shorten the term of any director. In the event of any increase or decrease in the authorized number of directors, (a) each director then serving as such shall continue as a director of the class of which he or she is a member and (b) the newly created or eliminated directorship resulting from such increase or decrease shall be apportioned by the Board of Directors among the classes of directors so as to make all classes as nearly equal in number as is practicable.

2.5.Any vacancy occurring in the Board of Directors for any cause, and any newly created directorship resulting from any increase in the authorized number of directors, shall be filled only by the affirmative vote of a majority of the directors then in office, even if less than a quorum, or by a sole remaining director, and shall not be filled by the stockholders. Any director elected in accordance with the preceding sentence shall hold office for a term expiring at the annual meeting of stockholders at which the term of office of the class to which the director has been assigned expires and until such director's successor shall have been duly elected and qualified, or until such director's earlier death, resignation, disqualification or removal.

2.6.The foregoing provisions of this Section 2 of Article VII shall not apply to any directorship elected separately by one or more classes or series of Preferred Stock hereinafter designated pursuant to Article IV, Section 2.1 unless the terms of such designation so provide.

2.7.In case of an ambiguity in the application of any provision set forth in this Section 2 of Article VII or in the meaning of any term or definition set forth in this Section 2 of Article VII (including any such term used in any other provision of this Restated Certificate of Incorporation), the Board of Directors, or a committee thereof, shall have the power to determine, in its sole discretion, the application of any such provision or any such term or definition with respect to any situation based on the facts believed in good faith by it. A determination of the Board of Directors (or a committee thereof, as applicable) in accordance with the preceding sentence shall be conclusive and binding on the stockholders of the Corporation. Such determination shall be evidenced in a writing adopted by the Board of Directors (or a committee thereof, as applicable), and such writing shall be made available for inspection by any holder of capital stock of the Corporation at the principal executive offices of the Corporation.

3. Vote by Ballot. Election of directors need not be by written ballot unless the Bylaws shall so provide.

ARTICLE VIII: DIRECTOR LIABILITY

1. Limitation of Liability.To the fullest extent permitted by law, no director of the Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director. Without limiting the effect of the preceding sentence, if the General Corporation Law is hereafter amended to authorize the further elimination or limitation of the liability of a director, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent permitted by the General Corporation Law, as so amended.

Annex C-ix

2. Change in Rights.Neither any amendment nor repeal of this Article VIII, nor the adoption of any provision of this Restated Certificate of Incorporation inconsistent with this Article VIII, shall eliminate, reduce or otherwise adversely affect any limitation on the personal liability of a director of the Corporation existing at the time of such amendment, repeal or adoption of such an inconsistent provision.

3. Advance Notice of Stockholder Nominations and Business Transacted at Special Meetings.Advance notice of stockholder nominations for the election of directors of the Corporation and of business to be brought by stockholders before any meeting of stockholders of the Corporation shall be given in the manner provided in the Bylaws. Business transacted at special meetings of stockholders shall be limited to the purpose or purposes stated in the notice of meeting.

Notwithstanding anything to the contrary herein, prior to an Automatic Conversion, and in addition to any other vote required pursuant to this Article XI, the Corporation shall not, without the prior

Annex C-x

ARTICLE XII: CHOICE OF FORUM; EXCLUSIVE FORUM

1.Unless the Corporation consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware) shall, to the fullest extent permitted by law, be the sole and exclusive forum for: (i) any derivative action or proceeding brought on behalf of the Corporation; (ii) any action asserting a claim that is based upon a breach of a fiduciary duty owed by, or other wrongdoing by, any current or former director, officer, stockholder, employee or agent of the Corporation to the Corporation or the Corporation's stockholders; (iii) any action asserting a claim against the Corporation or any current or former director, officer, stockholder, employee or agent of the Corporation arising pursuant to any provision of the General Corporation Law, this Restated Certificate of Incorporation or the Bylaws or as to which the General Corporation Law confers jurisdiction on the Court of Chancery of the State of Delaware; (iv) any action to interpret, apply, enforce or determine the validity of this Restated Certificate of Incorporation or the Bylaws; (v) any action asserting a claim against the Corporation governed by the internal affairs doctrine; or (vi) any action asserting an 'internal corporate claim' as that term is defined in Section 115 of the General Corporation Law.

RESTATED BYLAWS

As Adopted [ ], 2021 and

As Effective [ ], 2021

ARTICLE I: STOCKHOLDERS

Section 1.1: Annual Meetings. If required by applicable law, an annual meeting of stockholders shall be held for the election of directors at such date and time as the Board of Directors (the 'Board') of Nextdoor Holdings, Inc. (the 'Corporation') shall each year fix. The meeting may be held either at a place, within or without the State of Delaware as permitted by the Delaware General Corporation Law (the 'DGCL'), or by means of remote communication as the Board in its sole discretion may determine. Any proper business may be transacted at the annual meeting.

Section 1.2: Special Meetings. Special meetings of stockholders for any purpose or purposes shall be called in the manner set forth in the Restated Certificate of Incorporation of the Corporation (as the same may be amended and/or restated from time to time, the 'Certificate of Incorporation'). The special meeting may be held either at a place, within or without the State of Delaware, or by means of remote communication as the Board in its sole discretion may determine. Business transacted at any special meeting of stockholders shall be limited to matters relating to the purpose or purposes stated in the notice of the meeting.

Section 1.3: Notice of Meetings. Notice of all meetings of stockholders shall be given in writing or by electronic transmission in the manner provided by applicable law (including, without limitation, as set forth in Section 6.1.1 of these Bylaws) stating the date, time and place, if any, of the meeting, the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such meeting, and the record date for determining the stockholders entitled to vote at the meeting (if such date is different from the record date for determining the stockholders entitled to notice of the meeting). In the case of a special meeting, such notice shall also set forth the purpose or purposes for which the meeting is called. Unless otherwise required by applicable law or the Certificate of Incorporation, notice of any meeting of stockholders shall be given not less than ten (10), nor more than sixty (60), days before the date of the meeting to each stockholder of record entitled to vote at such meeting as of the record date for determining the stockholders entitled to notice of the meeting.

Section 1.4: Adjournments. Notwithstanding Section 1.5 of these Bylaws, the chairperson of the meeting shall have the power to adjourn the meeting to another time, date and place (if any) regardless of whether a quorum is present, at any time and for any reason. Any meeting of stockholders, annual or special, may be adjourned from time to time, and notice need not be given of any such adjourned meeting if the time, date and place (if any) thereof and the means of remote communication (if any) by which stockholders and proxy holders may be deemed to be present in person and vote at such adjourned meeting are announced at the meeting at which the adjournment is taken; provided, however, that if the adjournment is for more than thirty (30) days, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting. If, after the adjournment, a new record date for determination of stockholders entitled to vote is fixed for the adjourned meeting, the Board shall fix as the record date for determining stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote at the adjourned meeting, and shall give notice of the adjourned meeting to each stockholder of record as of the record date so fixed for notice of such adjourned meeting. At the adjourned meeting, the Corporation may transact any business that might have been transacted at the original meeting. To the fullest extent permitted by law, if a quorum is present at the original meeting, it shall also be deemed present at the adjourned meeting. To the fullest extent permitted by law, the Board may postpone, reschedule or cancel at any time and for any reason any previously scheduled special or annual meeting of

Annex D-i

stockholders before it (or any adjournment) is to be held, regardless of whether any notice or public disclosure with respect to any such meeting (or adjournment) has been sent or made pursuant to Section 1.3 hereof or otherwise, in which case notice shall be provided to the stockholders of the new date, time and place, if any, of the meeting as provided in Section 1.3 above.

Section 1.5: Quorum. Except as otherwise required by applicable law or as provided by the Certificate of Incorporation or these Bylaws, at each meeting of stockholders the holders of a majority of the voting power of the shares of stock issued and outstanding and entitled to vote at the meeting, present in person or represented by proxy, shall constitute a quorum for the transaction of business; provided, however, that where a separate vote by a class or classes or series of stock is required by applicable law or the Certificate of Incorporation, the holders of a majority of the voting power of the shares of such class or classes or series of the stock issued and outstanding and entitled to vote on such matter, present in person or represented by proxy at the meeting, shall constitute a quorum entitled to take action with respect to the vote on such matter. If a quorum shall fail to attend any meeting, the chairperson of the meeting or, if directed to be voted on by the chairperson of the meeting, the holders of a majority of the voting power of the shares entitled to vote who are present in person or represented by proxy at the meeting may adjourn the meeting. Shares of the Corporation's stock belonging to the Corporation (or to another corporation, if a majority of the shares entitled to vote in the election of directors of such other corporation are held, directly or indirectly, by the Corporation), shall neither be entitled to vote nor be counted for quorum purposes;provided, however, that the foregoing shall not limit the right of the Corporation or any other corporation to vote any shares of the Corporation's stock held by it in a fiduciary capacity and to count such shares for purposes of determining a quorum. A quorum, once established at a meeting, shall not be broken by the withdrawal of enough votes to leave less than a quorum, including, to the fullest extent permitted by law, at any adjournment thereof (unless a new record date is fixed for the adjourned meeting).

Section 1.6: Organization. Meetings of stockholders shall be presided over by (a) such person as the Board may designate, or (b) in the absence of such a person, the Chairperson of the Board, or (c) in the absence of such person, the Lead Independent Director, or, (d) in the absence of such person, the Chief Executive Officer of the Corporation, or (e) in the absence of such person, the President of the Corporation, or (f) in the absence of such person, by a Vice President. The Secretary of the Corporation shall act as secretary of the meeting, but in such person's absence the chairperson of the meeting may appoint any person to act as secretary of the meeting.

Section 1.7: Voting; Proxies. Each stockholder of record entitled to vote at a meeting of stockholders may authorize another person or persons to act for such stockholder by proxy. Such a proxy may be prepared, transmitted and delivered in any manner permitted by applicable law. Except as may be required in the Certificate of Incorporation, directors shall be elected by a plurality of the votes cast by the holders of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors. At all meetings of stockholders at which a quorum is present, unless a different or minimum vote is required by applicable law, rule or regulation applicable to the Corporation or its securities, the rules or regulations of any stock exchange applicable to the Corporation, the Certificate of Incorporation or these Bylaws, in which case such different or minimum vote shall be the applicable vote on the matter, every matter other than the election of directors shall be decided by the affirmative vote of the holders of a majority of the voting power of the shares of stock entitled to vote on such matter that are present in person or represented by proxy at the meeting and are voted for or against the matter (or if there are two or more classes or series of stock entitled to vote as separate classes, then in the case of each class or series, the holders of a majority of the voting power of the shares of stock of that class or series present in person or represented by proxy at the meeting voting for or against such matter).

Section 1.8: Fixing Date for Determination of Stockholders of Record. In order that the Corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board, and which record date shall, unless otherwise required by law, not be more than sixty (60) nor less than ten (10) days before the date of such meeting. If the Board so fixes a date, such date shall also be the record date for determining the stockholders entitled to vote at such meeting unless the Board determines, at the time it fixes such record date, that a later date on or before the date of the meeting shall be the date for making such determination. If no record date is fixed by the Board, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at 5:00 p.m. Eastern Time on the

Annex D-ii

day next preceding the day on which notice is given, or, if notice is waived, at 5:00 p.m. Eastern Time on the day next preceding the day on which the meeting is held. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board may fix a new record date for determination of stockholders entitled to vote at the adjourned meeting, and in such case shall also fix as the record date for stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote in accordance herewith at the adjourned meeting.

In order that the Corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board may fix, in advance, a record date, which shall not precede the date upon which the resolution fixing the record date is adopted by the Board and which shall not be more than sixty (60) days prior to such action. If no such record date is fixed by the Board, then the record date for determining stockholders for any such purpose shall be at 5:00 p.m. Eastern Time on the day on which the Board adopts the resolution relating thereto.

Section 1.9: List of Stockholders Entitled to Vote. The Corporation shall prepare, at least ten (10) days before every meeting of stockholders, a complete list of stockholders entitled to vote at the meeting (provided, however, if the record date for determining the stockholders entitled to vote is less than ten (10) days before the date of the meeting, the list shall reflect the stockholders entitled to vote as of the tenth (10th) day before the meeting date), arranged in alphabetical order and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Nothing herein shall require the Corporation to include electronic mail addresses or other electronic contact information on such list. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, for a period of at least ten (10) days prior to the meeting, (a) on a reasonably accessible electronic network as permitted by applicable law (providedthat the information required to gain access to the list is provided with the notice of the meeting), or (b) during ordinary business hours, at the principal place of business of the Corporation. If the meeting is held at a location where stockholders may attend in person, a list of stockholders entitled to vote at the meeting shall also be produced and kept at the time and place of the meeting during the whole time thereof and may be examined by any stockholder who is present at the meeting. If the meeting is held solely by means of remote communication, then the list shall be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access the list shall be provided with the notice of the meeting. Except as otherwise provided by law, the stock ledger shall be the only evidence as to who are the stockholders entitled to examine the list of stockholders required by this Section 1.9 or to vote in person or by proxy at any meeting of stockholders.

Section 1.10: Inspectors of Elections.

1.10.1 Applicability. Unless otherwise required by the Certificate of Incorporation or by applicable law, the following provisions of this Section 1.10 shall apply only if and when the Corporation has a class of voting stock that is: (a) listed on a national securities exchange; (b) authorized for quotation on an interdealer quotation system of a registered national securities association; or (c) held of record by more than two thousand (2,000) stockholders. In all other cases, observance of the provisions of this Section 1.10 shall be optional, and at the discretion of the Board.

1.10.2 Appointment. The Corporation shall, in advance of any meeting of stockholders, appoint one or more inspectors of election to act at the meeting and make a written report thereof. The Corporation may designate one or more persons as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate is able to act at a meeting of stockholders, the chairperson of the meeting shall appoint one or more inspectors to act at the meeting.

1.10.3 Inspector's Oath. Each inspector of election, before entering upon the discharge of his duties, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of such inspector's ability.

1.10.4 Duties of Inspectors. At a meeting of stockholders, the inspectors of election shall (a) ascertain the number of shares outstanding and the voting power of each share, (b) determine the shares represented at a

Annex D-iii

meeting and the validity of proxies and ballots, (c) count all votes and ballots, (d) determine and retain for a reasonable period of time a record of the disposition of any challenges made to any determination by the inspectors, and (e) certify their determination of the number of shares represented at the meeting, and their count of all votes and ballots. The inspectors may appoint or retain other persons or entities to assist the inspectors in the performance of the duties of the inspectors.

1.10.5 Opening and Closing of Polls. The date and time of the opening and the closing of the polls for each matter upon which the stockholders will vote at a meeting shall be announced at the meeting. No ballot, proxies or votes, nor any revocations thereof or changes thereto, shall be accepted by the inspectors after the closing of the polls unless the Court of Chancery upon application by a stockholder shall determine otherwise.

1.10.6 Determinations. In determining the validity and counting of proxies and ballots, the inspectors shall be limited to an examination of the proxies, any envelopes submitted with those proxies, any information provided in connection with proxies pursuant to Section 211(a)(2)b.(i) of the DGCL, or in accordance with Sections 211(e) or 212(c)(2) of the DGCL, ballots and the regular books and records of the Corporation, except that the inspectors may consider other reliable information for the limited purpose of reconciling proxies and ballots submitted by or on behalf of banks, brokers, their nominees or similar persons which represent more votes than the holder of a proxy is authorized by the record owner to cast or more votes than the stockholder holds of record. If the inspectors consider other reliable information for the limited purpose permitted herein, the inspectors at the time they make their certification of their determinations pursuant to this Section 1.10 shall specify the precise information considered by them, including the person or persons from whom they obtained the information, when the information was obtained, the means by which the information was obtained and the basis for the inspectors' belief that such information is accurate and reliable.

Section 1.11: Conduct of Meetings. The Board may adopt by resolution such rules and regulations for the conduct of the meeting of stockholders as it shall deem appropriate. Except to the extent inconsistent with such rules and regulations as adopted by the Board, the chairperson of any meeting of stockholders shall have the right and authority to convene and (for any reason) to recess and/or adjourn the meeting, to prescribe such rules, regulations and procedures and to do all such acts as, in the judgment of such chairperson, are appropriate for the proper conduct of the meeting. Such rules, regulations or procedures, whether adopted by the Board or prescribed by the chairperson of the meeting, may include, without limitation, the following: (a) the establishment of an agenda or order of business for the meeting; (b) rules and procedures for maintaining order at the meeting and the safety of those present; (c) limitations on attendance at or participation in the meeting to stockholders entitled to vote at the meeting, their duly authorized and constituted proxies or such other persons as the chairperson of the meeting shall determine; (d) restrictions on entry to the meeting after the time fixed for the commencement thereof; (e) limitations on the time (if any) allotted to questions or comments by participants; (f) restricting the use of audio/video recording devices and cell phones; and (g) complying with any state and local laws and regulations concerning safety and security. The chairperson of any meeting of stockholders, in addition to making any other determinations that may be appropriate to the conduct of the meeting, shall, if the facts warrant, determine and declare to the meeting that a matter or business was not properly brought before the meeting and if such chairperson should so determine, such chairperson shall so declare to the meeting and any such matter or business not properly brought before the meeting shall not be transacted or considered. Unless and to the extent determined by the Board or the chairperson of the meeting, meetings of stockholders shall not be required to be held in accordance with the rules of parliamentary procedure.

Notwithstanding the foregoing, the Board may provide by resolution or resolutions that some or all of any or all classes or series of its stock shall be certificated shares. Every holder of stock represented by certificates shall be entitled to have a certificate signed by, or in the name of the Corporation, by any two authorized officers of the Corporation (it being understood that each of the Chairperson of the Board, the Vice-Chairperson of the Board, the Chief Executive Officer, the President, any Vice President, the Treasurer, any Assistant Treasurer, the Secretary, and any Assistant Secretary shall be an authorized officer for such purpose), representing the number of shares registered in certificate form.

Except as otherwise required by law, notice may be given in writing directed to a stockholder's mailing address as it appears on the records of the Corporation and shall be given: (a) if mailed, when notice is deposited in the U.S. mail, postage prepaid; and (b) if delivered by courier service, the earlier of when the notice is received or left at such stockholder's address. So long as the Corporation is subject to the Securities and Exchange Commission's proxy rules set forth in Regulation 14A under the Exchange Act, notice shall be given in the manner required by such rules. To the extent permitted by such rules, or if the Corporation is not subject to Regulation 14A, notice may be given by electronic transmission directed to the stockholder's electronic mail address, and if so given, shall be given when directed to such stockholder's electronic mail address unless the stockholder has notified the Corporation in writing or by electronic transmission of an objection to receiving notice by electronic mail or such notice is prohibited by Section 232(e) of the DGCL. If notice is given by electronic mail, such notice shall comply with the applicable provisions of Sections 232(a) and 232(d) of the DGCL. Notice may be given by other forms of electronic transmission with the consent of a stockholder in the manner permitted by Section 232(b) of the DGCL and shall be deemed given as provided therein.

6.1.2 Affidavit of Giving Notice. An affidavit of the Secretary or an Assistant Secretary or of the transfer agent or other agent of the Corporation that the notice has been given in writing or by a form of electronic transmission shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

Whenever notice is required to be given under any provision of the DGCL, the Certificate of Incorporation or these Bylaws, a written waiver of notice, signed by the person entitled to notice, or waiver by electronic transmission by such person, whether before or after the time stated therein, shall be deemed equivalent to notice. Attendance of a person at a meeting shall constitute a waiver of notice of such meeting, except when the person attends a meeting for the express purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the stockholders, directors or members of a committee of directors need be specified in any waiver of notice.

ARTICLE VII: INTERESTED DIRECTORS

Section 7.1: Interested Directors. No contract or transaction between the Corporation and one or more of its members of the Board or officers, or between the Corporation and any other corporation, partnership, association or other organization in which one or more of its directors or officers are members of the board of directors or officers, or have a financial interest, shall be void or voidable solely for this reason, or solely because the director or officer is present at or participates in the meeting of the Board or committee thereof that authorizes the contract or transaction, or solely because his, her or their votes are counted for such purpose, if: (a) the material facts as to his, her or their relationship or interest and as to the contract or transaction are disclosed or are known to the Board or the committee, and the Board or committee in good faith authorizes the contract or transaction by the affirmative votes of a majority of the disinterested directors, even though the disinterested directors be less than a quorum; (b) the material facts as to his, her or their relationship or interest and as to the contract or transaction are

Annex D-xv

disclosed or are known to the stockholders entitled to vote thereon, and the contract or transaction is specifically approved in good faith by vote of the stockholders; or (c) the contract or transaction is fair as to the Corporation as of the time it is authorized, approved or ratified by the Board, a committee thereof, or the stockholders.

Section 7.2: Quorum. Interested directors may be counted in determining the presence of a quorum at a meeting of the Board or of a committee which authorizes a contract or transaction described in Section 7.1 of this Article VII.

ARTICLE VIII: INDEMNIFICATION

Section 8.1: Right to Indemnification. To the fullest extent permitted by applicable law, as the same exists or may hereafter be amended, the Corporation shall indemnify and hold harmless each person who was or is made a party or is threatened to be made a party to or is otherwise involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a 'proceeding'), by reason of the fact that he or she is or was a director or officer of the Corporation or, while a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, other enterprise or nonprofit entity, including service with respect to an employee benefit plan (hereinafter an 'Indemnitee'), whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent, or in any other capacity while serving as a director, officer, employee or agent, against all liability and loss suffered and expenses (including, without limitation, attorneys' fees, judgments, fines, ERISA excise taxes and penalties and amounts paid in settlement) reasonably incurred by such Indemnitee in connection with such proceeding; provided, however, that, except as provided in Section 8.3 with respect to proceedings to enforce rights to indemnification, the Corporation shall indemnify an Indemnitee in connection with a proceeding (or part thereof) initiated by such Indemnitee only if such proceeding (or part thereof) was authorized by the Board.

Section 8.2: Right to Advancement of Expenses. In addition to the right to indemnification conferred in Section 8.1, an Indemnitee shall also have the right to be paid by the Corporation to the fullest extent not prohibited by applicable law the expenses (including, without limitation, attorneys' fees) incurred in defending or otherwise participating in any such proceeding in advance of its final disposition (hereinafter an 'advancement of expenses'); provided, however, that, if the DGCL requires, an advancement of expenses incurred by an Indemnitee in his or her capacity as a director or officer of the Corporation (and not in any other capacity in which service was or is rendered by such Indemnitee, including, without limitation, service to an employee benefit plan) shall be made only upon the Corporation's receipt of an undertaking (hereinafter an 'undertaking'), by or on behalf of such Indemnitee, to repay all amounts so advanced if it shall ultimately be determined that such Indemnitee is not entitled to be indemnified under this Article VIII or otherwise.

Section 8.3: Right of Indemnitee to Bring Suit. If a claim under Section 8.1 or Section 8.2 is not paid in full by the Corporation within 60 days after a written claim therefor has been received by the Corporation, except in the case of a claim for an advancement of expenses, in which case the applicable period shall be 20 days, the Indemnitee may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim. If successful in whole or in part in any such suit, or in a suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Indemnitee shall also be entitled to be paid the expense of prosecuting or defending such suit. In (a) any suit brought by the Indemnitee to enforce a right to indemnification hereunder (but not in a suit brought by an Indemnitee to enforce a right to an advancement of expenses) it shall be a defense that, and (b) in any suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Corporation shall be entitled to recover such expenses upon a final judicial decision from which there is no further right to appeal (hereinafter a 'final adjudication') that, the Indemnitee has not met any applicable standard for indemnification set forth in the DGCL. Neither the failure of the Corporation (including its directors who are not parties to such action, a committee of such directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such suit that indemnification of the Indemnitee is proper in the circumstances because the Indemnitee has met the applicable standard of conduct set forth in the DGCL, nor an actual determination by the Corporation (including a determination by its directors who are not parties to such action, a committee of such directors, independent legal counsel, or its stockholders) that the Indemnitee has not met such applicable standard of conduct, shall create a

Annex D-xvi

presumption that the Indemnitee has not met the applicable standard of conduct or, in the case of such a suit brought by the Indemnitee, shall be a defense to such suit. In any suit brought by the Indemnitee to enforce a right to indemnification or to an advancement of expenses hereunder, or by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the burden of proving that the Indemnitee is not entitled to be indemnified, or to such advancement of expenses, under this Article VIII or otherwise shall be on the Corporation.

Section 8.4: Non-Exclusivity of Rights. The rights provided to any Indemnitee pursuant to this Article VIII shall not be exclusive of any other right, which such Indemnitee may have or hereafter acquire under applicable law, the Certificate of Incorporation, these Bylaws, an agreement, a vote of stockholders or disinterested directors, or otherwise.

Section 8.5: Insurance. The Corporation may maintain insurance, at its expense, to protect itself and/or any director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the DGCL.

Section 8.6: Indemnification of Other Persons. This Article VIII shall not limit the right of the Corporation to the extent and in the manner authorized or permitted by law to indemnify and to advance expenses to persons other than Indemnitees. Without limiting the foregoing, the Corporation may, to the extent authorized from time to time by the Board, grant rights to indemnification and to the advancement of expenses to any employee or agent of the Corporation and to any other person who is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan, to the fullest extent of the provisions of this Article VIII with respect to the indemnification and advancement of expenses of Indemnitees under this Article VIII.

Section 8.7: Amendments. Any repeal or amendment of this Article VIII by the Board or the stockholders of the Corporation or by changes in applicable law, or the adoption of any other provision of these Bylaws inconsistent with this Article VIII, will, to the extent permitted by applicable law, be prospective only (except to the extent such amendment or change in applicable law permits the Corporation to provide broader indemnification rights to Indemnitees on a retroactive basis than permitted prior thereto), and will not in any way diminish or adversely affect any right or protection existing hereunder in respect of any act or omission occurring prior to such repeal or amendment or adoption of such inconsistent provision; provided, however, that amendments or repeals of this Article VIII shall require the affirmative vote of the stockholders holding at least 66.7% of the voting power of all outstanding shares of capital stock of the Corporation.

Section 8.8: Certain Definitions. For purposes of this Article VIII, (a) references to 'other enterprise' shall include any employee benefit plan; (b) references to 'fines' shall include any excise taxes assessed on a person with respect to an employee benefit plan; (c) references to 'serving at the request of the Corporation' shall include any service that imposes duties on, or involves services by, a person with respect to any employee benefit plan, its participants, or beneficiaries; and (d) a person who acted in good faith and in a manner such person reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner 'not opposed to the best interest of the Corporation' for purposes of Section 145 of the DGCL.

Section 8.9: Contract Rights. The rights provided to Indemnitees pursuant to this Article VIII shall be contract rights and such rights shall continue as to an Indemnitee who has ceased to be a director, officer, agent or employee and shall inure to the benefit of the Indemnitee's heirs, executors and administrators.

Section 8.10: Severability. If any provision or provisions of this Article VIII shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Article VIII shall not in any way be affected or impaired thereby; and (b) to the fullest extent possible, the provisions of this Article VIII (including, without limitation, each such portion of this Article VIII containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested by the provision held invalid, illegal or unenforceable.

Section 9.6: Severability. If any provision of these Bylaws shall be held to be invalid, illegal, unenforceable or in conflict with the provisions of the Certificate of Incorporation, then such provision shall nonetheless be enforced to the maximum extent possible consistent with such holding and the remaining provisions of these Bylaws (including without limitation, all portions of any section of these Bylaws containing any such provision held to be invalid, illegal, unenforceable or in conflict with the Certificate of Incorporation, that are not themselves invalid, illegal, unenforceable or in conflict with the Certificate of Incorporation) shall remain in full force and effect.

Section 9.7: Time Periods.

(f) The Investor acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Shares, including those set forth in the SEC Reports.

The Investor further represents that the Investor maintains policies and procedures reasonably designed to ensure that the funds held by the Investor and used to purchase the Shares were legally derived and were not obtained, directly or indirectly, from a Prohibited Investor.

Annex E-ix

(r) The Investor acknowledges and agrees that it is not an underwriter within the meaning of Section 2(a)(11) of the Securities Act and that the purchase and sale of Shares hereunder meets the exemptions from filing under FINRA Rule 5123(b)(1).

(s) No foreign person (as defined in 31 C.F.R. Part 800.224) in which the national or subnational governments of a single foreign state have a substantial interest (as defined in 31 C.F.R. Part 800.244) will acquire a substantial interest in KVSB as a result of the purchase and sale of Shares hereunder such that a declaration to the Committee on Foreign Investment in the United States would be mandatory under 31 C.F.R. Part 800.401, and no foreign person will have control (as defined in 31 C.F.R. Part 800.208) over KVSB from and after the Closing as a result of the purchase and sale of Shares hereunder.

7. Registration Rights.

(a) KVSB agrees that, within thirty (30) calendar days following the Closing Date (such deadline, the 'Filing Deadline'), KVSB will submit to or file with the SEC (at its sole cost and expense) a registration statement for a shelf registration on Form S-1 or Form S-3 (if KVSB is then eligible to use a Form S-3 shelf registration) (the 'Registration Statement'), in each case, covering the resale of the Shares acquired by the Investor pursuant to this Subscription Agreement (the 'Registrable Shares') and KVSB shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) the ninetieth (90th) calendar day following the Closing Date if the SEC notifies KVSB that it will 'review' the Registration Statement and (ii) the fifth (5th) business day after the date KVSB is notified (orally or in writing, whichever is earlier) by the SEC that the Registration Statement will not be 'reviewed' or will not be subject to further review (such earlier date, the 'Effectiveness Deadline'); provided, however,that if the Effectiveness Deadline falls on a Saturday, Sunday or other day that the SEC is closed for business, the Effectiveness Deadline shall be extended to the next business day on which the SEC is open for business; and provided, further,that (x) KVSB shall use its commercially reasonable efforts to provide a draft of the initial Registration Statement to the Investor for review at least three (3) business days in advance of the filing of the initial Registration Statement, so long as KVSB shall not be required to delay or postpone the filing of such initial Registration Statement as a result of or in connection with the Investor's review; and (y) KVSB's obligations to include the Registrable Shares in the Registration Statement are contingent upon the Investor furnishing in writing to KVSB such information regarding the Investor, the securities of KVSB held by the Investor and the intended method of disposition of the Registrable Shares (which shall be limited to non-underwritten public offerings) as shall be reasonably requested by KVSB to effect the registration of the Registrable Shares, and the Investor shall execute such documents in connection with such registration as KVSB may reasonably request that are customary of a selling stockholder in similar situations; providedthat the Investor shall not in connection with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to transfer the Registrable Shares. The Registration Statement shall include a 'plan of distribution' that permits all lawful means of disposition of the Registrable Shares by the Investor, including block sales, agented transactions, sales directly into the market and other customary provisions (but, excluding for the avoidance of doubt, underwritten offerings). Notwithstanding the foregoing, if the SEC prevents KVSB from including any or all of the shares proposed to be registered under the Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of the Shares by the applicable shareholders or otherwise, such Registration Statement shall register for resale such number of Shares which is equal to the maximum number of Shares as is permitted by the SEC. In such event, the number of Shares to be registered for each selling shareholder named in the Registration Statement shall be reduced pro rata among all such selling shareholders, and as promptly as practicable after being permitted to register additional shares under Rule 415 under the Securities Act, KVSB shall amend the Registration Statement or file one or more new Registration Statement(s) (such new Registration Statement shall also be deemed to be 'Registration Statement' hereunder) to register such additional subscribed Shares and cause such amendment or Registration Statement(s) to become effective as promptly as practicable after the filing thereof. Unless otherwise agreed to in writing by the Investor, the Investor shall not be identified as a statutory underwriter

Annex E-x

in the Registration Statement unless requested by the SEC; provided, that if the SEC requests that Investor be identified as a statutory underwriter in the Registration Statement, Investor will have the opportunity to withdraw from the Registration Statement upon its prompt written request to KVSB. For as long as the Investor holds Shares, KVSB will use commercially reasonable efforts to file all reports for so long as the condition in Rule 144(c)(1) (or Rule 144(i)(2), if applicable) is required to be satisfied, and provide all customary and reasonable cooperation, necessary to enable the undersigned to resell the Shares acquired hereunder pursuant to Rule 144 of the Securities Act (in each case, when Rule 144 of the Securities Act becomes available to the Investors), including providing customary and reasonable legal opinions to KVSB's transfer agent. Any failure by KVSB to file the Registration Statement by the Filing Deadline or to effect such Registration Statement by the Effectiveness Deadline shall not otherwise relieve KVSB of its obligations to file or effect the Registration Statement as set forth above in this Section 7.

(b) In the case of the registration effected by KVSB pursuant to this Subscription Agreement, KVSB shall, upon reasonable request, inform the Investor as to the status of such registration. At its expense, KVSB shall:

(i) except for such times as KVSB is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under state securities laws which KVSB determines to obtain, continuously effective with respect to Investor, and to keep the applicable Registration Statement or any subsequent shelf registration statement free of any material misstatements or omissions, until the earlier of the following: (A) the Investor ceases to hold any Registrable Shares, (B) the date all Registrable Shares held by the Investor may be sold without restriction under Rule 144 and without the requirement for KVSB to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable), including without limitation, any volume and manner of sale restrictions which may be applicable to affiliates under Rule 144, and (C) two (2) years from the date of effectiveness of the Registration Statement. The period of time during which KVSB is required hereunder to keep a Registration Statement effective is referred to herein as the 'Registration Period';

(ii) during the Registration Period, advise the Investor, as expeditiously as possible:

(1) when a Registration Statement or any amendment thereto has been filed with the SEC;

(2) after it shall receive notice or obtain knowledge thereof, of the issuance by the SEC of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose;

(3) of the receipt by KVSB of any notification with respect to the suspension of the qualification of the Registrable Shares included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

(4) subject to the provisions in this Subscription Agreement, of the occurrence of any event that requires the making of any changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading.

Notwithstanding anything to the contrary set forth herein, KVSB shall not, when so advising the Investor of such events, provide the Investor with any material, nonpublic information regarding KVSB other than to the extent that providing notice to the Investor of the occurrence of the events listed in (1) through (4) above may constitute material, nonpublic information regarding KVSB;

(iii) during the Registration Period, use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable;

(iv) during the Registration Period, upon the occurrence of any event contemplated in Section 7(b)(ii)(4)above, except for such times as KVSB is permitted hereunder to suspend, and has suspended, the

Annex E-xi

use of a prospectus forming part of a Registration Statement, KVSB shall use its commercially reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Registrable Shares included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(v) during the Registration Period, use its commercially reasonable efforts to cause all Registrable Shares to be listed on each securities exchange or market, if any, on which the Shares have been listed;

(vi) during the Registration Period, use its commercially reasonable efforts to allow the Investor to review disclosure regarding the Investor in the Registration Statement; and

(vii) otherwise, in good faith, during the Registration Period, cooperate reasonably with, and take such customary actions as may reasonably be requested by the Investor, consistent with the terms of this Subscription Agreement, in connection with the registration of the Registrable Shares.

(c) Notwithstanding anything to the contrary in this Subscription Agreement, KVSB shall be entitled to delay the filing or effectiveness of, or suspend the use of, the Registration Statement if it determines that in order for the Registration Statement not to contain a material misstatement or omission, (i) an amendment thereto would be needed to include information that would at that time not otherwise be required in a current, quarterly, or annual report under the Exchange Act, or (ii) the negotiation or consummation of a transaction by KVSB or its subsidiaries is pending or an event has occurred, which negotiation, consummation or event KVSB's board of directors reasonably believes, upon advice of legal counsel, would require additional disclosure by KVSB in the Registration Statement of material information that KVSB has a bona fide business purpose for keeping confidential and the non-disclosure of which in the Registration Statement would be expected, in the reasonable determination of KVSB's board of directors, upon advice of legal counsel, to cause the Registration Statement to fail to comply with applicable disclosure requirement (each such circumstance, a 'Suspension Event'); provided, however,that KVSB may not delay or suspend the Registration Statement on more than two occasions or for more than sixty (60) consecutive calendar days, or more than ninety (90) total calendar days, in each case, during any twelve-month period. Upon receipt of any written notice from KVSB of the happening of any Suspension Event during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein (in light of the circumstances under which they were made, in the case of the prospectus) not misleading, the Investor agrees that (i) it will immediately discontinue offers and sales of the Registrable Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until the Investor receives copies of a supplemental or amended prospectus (which KVSB agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by KVSB that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by KVSB unless otherwise required by law or subpoena; providedthat, for the avoidance of doubt, such written notice shall not include any material non-public information with respect to KVSB. If so directed by KVSB, the Investor will deliver to KVSB or, in the Investor's sole discretion destroy, all copies of the prospectus covering the Registrable Shares in Investor's possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Registrable Shares shall not apply (A) to the extent the Investor is required to retain a copy of such prospectus (1) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (2) in accordance with a bona fide pre-existing document retention policy or (B) to copies stored electronically on archival servers as a result of automatic data back-up. The Investor may deliver written notice (an 'Opt-Out Notice') to KVSB requesting that the Investor not receive notices from KVSB regarding the suspension of the Registration Statement; provided, however,that the Investor may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from the Investor (unless subsequently revoked), (i) KVSB shall not deliver any such notices to the Investor and the Investor shall no longer be entitled to the rights associated with any such notice and (ii) each time prior to the Investor's intended use of an effective Registration Statement, the Investor will notify KVSB in writing at least two (2) business days in advance of such intended use, and if a notice of a suspension was previously delivered (or would have been delivered but for the provisions of this

Annex E-xii

Section 7(c)and the related suspension period remains in effect), KVSB will so notify the Investor, within one (1) business day after the Investor's notification to KVSB, by delivering to the Investor a copy of such previous notice of suspension, and thereafter will provide the Investor with the related notice of the conclusion of such suspension promptly following its availability.

(d) Indemnification.

(i) KVSB agrees to indemnify, to the extent permitted by law, the Investor (to the extent a seller under the Registration Statement), its directors, officers, employees, advisers and agents, and each person or entity who controls the Investor (within the meaning of the Securities Act), to the extent not prohibited by law, against all losses, claims, damages, liabilities and reasonable and documented out of pocket expenses (including, without limitation, reasonable and documented outside attorneys') as incurred caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, prospectus included in any Registration Statement or preliminary prospectus or any amendment thereof or supplement thereto or document incorporated by reference therein or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading, except insofar as the same are solely caused by or contained in any information or affidavit so furnished in writing to KVSB by or on behalf of the Investor expressly for use therein.

(ii) In connection with any Registration Statement in which the Investor is participating, the Investor shall furnish (or cause to be furnished) to KVSB in writing such information and affidavits as KVSB reasonably requests for use in connection with any such Registration Statement or prospectus and, to the extent not prohibited by law, shall indemnify KVSB, its directors, officers, employees, advisers and agents, and each person or entity who controls KVSB (within the meaning of the Securities Act), to the extent not prohibited by law, against all losses, claims, damages, liabilities and expenses (including, without limitation, reasonable and documented outside attorneys' fees) actually incurred as a result of any untrue or alleged untrue statement of material fact contained or incorporated by reference in any Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or document incorporated by reference therein or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading, but only to the extent that such untrue statement or omission is contained (or not contained in, in the case of an omission) in any information or affidavit so furnished in writing by on behalf of the Investor expressly for use therein; provided, however,that the liability of the Investor shall be several and not joint and shall be in proportion to and limited to the net proceeds received by the Investor from the sale of Registrable Shares giving rise to such indemnification obligation.

(iii) Any person or entity entitled to indemnification herein shall (A) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (providedthat the failure to give prompt notice shall not impair any person's or entity's right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (B) unless in such indemnified party's reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party (which consent shall not be unreasonably withheld, conditioned or delayed), consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement includes a statement or admission of fault and

Annex E-xiii

culpability on the part of such indemnified party or which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

(iv) The indemnification provided for under this Subscription Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person or entity of such indemnified party and shall survive the transfer of the Shares.

(v) If the indemnification provided under this Section 7(d)from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations; provided, however,the aggregate liability of the Investor under this Section 7shall be limited to the net proceeds received by the Investor from the sale of Registrable Shares giving rise to such indemnification obligation. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by (or not made by, in the case of an omission), or relates to information supplied by (or not supplied by, in the case of an omission), such indemnifying party or indemnified party, and the indemnifying party's and indemnified party's relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in Sections 7(d)(i), (ii)and (iii)above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 7(d)(v)from any person or entity who was not guilty of such fraudulent misrepresentation.

(e) For purposes of this Section 7,'Shares' shall mean, as of any date of determination, the subscribed Shares (as defined in the recitals to this Subscription Agreement) and any other equity security issued or issuable with respect to the subscribed Shares by way of share split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event, and 'Investor' shall include any affiliate of the Investor to which the rights under this Section 7shall have been duly assigned.

(f) In connection with any sale, assignment, transfer or other disposition of the subscribed Shares by the Investor pursuant to Rule 144 or pursuant to any other exemption under the Securities Act such that the Shares held by the Investor become freely tradable and upon compliance by the Investor with the requirements of this Section 7(f),if requested by the Investor, KVSB shall cause the transfer agent for the Shares (the 'Transfer Agent') to remove any restrictive legends related to the book entry account holding such shares and make a new, unlegended entry for such book entry shares sold or disposed of without restrictive legends within three (3) trading days of any such request therefor from the Investor, provided that KVSB and the Transfer Agent have timely received from the Investor customary representations and other documentation reasonably acceptable to KVSB and the Transfer Agent in connection therewith. Subject to receipt from the Investor by KVSB and the Transfer Agent of customary representations (including a representation that Investor will only sell the Shares in accordance with an effective registration statement or Rule 144) and other documentation reasonably acceptable to KVSB and the Transfer Agent in connection therewith, the Investor may request that KVSB remove any legend from the book entry position evidencing its subscribed Shares and KVSB will, if required by the Transfer Agent, cause an opinion of KVSB's counsel be provided, in a form reasonably acceptable to the Transfer Agent, to the effect that the removal of such restrictive legends in such circumstances may be effected under the Securities Act, following the earliest of such time as such Shares (i) (x) are subject to or (y) have been or are about to be sold or transferred pursuant to an effective registration statement, (ii) have been sold pursuant to Rule 144, or (iii) are eligible for resale under Rule 144(b)(1) or any successor provision without the requirement for KVSB to be in compliance with the current public information requirement under Rule 144 and without volume or manner-of-sale restrictions applicable to the sale or transfer of such shares. If restrictive legends are no longer required for such Shares pursuant to the foregoing, KVSB

Annex E-xiv

shall, in accordance with the provisions of this section and within three (3) trading days of any request therefor from the Investor accompanied by such customary and reasonably acceptable representations and other documentation referred to above establishing that restrictive legends are no longer required, deliver to the Transfer Agent irrevocable instructions that the Transfer Agent shall make a new, unlegended entry for such book entry shares. KVSB shall be responsible for the fees of its Transfer Agent, its legal counsel and all DTC fees associated with such issuance and the Investor shall be responsible for all other fees and expenses (including, without limitation, any applicable broker fees, fees and disbursements of their legal counsel and any applicable transfer taxes).

8. Termination.This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earliest to occur of (i) such date and time as the Transaction Agreement is terminated in accordance with its terms, (ii) upon the mutual written agreement of each of the parties hereto to terminate this Subscription Agreement, (iii) if the conditions to Closing set forth in Section 3of this Subscription Agreement are not satisfied, or are not capable of being satisfied, on or prior to the Closing and, as a result thereof, the transactions contemplated by this Subscription Agreement will not be or are not consummated at the Closing and (iv) on or after the date that is 270 days after the date hereof if the Closing has not occurred on or prior to such date; providedthat nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities or damages arising from any such willful breach. KVSB shall notify the Investor of the termination of the Transaction Agreement promptly after the termination of such agreement. Upon the termination of this Subscription Agreement in accordance with this Section 8,any monies paid by the Investor to KVSB in connection herewith shall be promptly (and in any event within one (1) business day after such termination) returned to the Investor without any deduction.

9. Investor Covenant.The Investor hereby agrees that, from the date of this Subscription Agreement, none of the Investor, its controlled affiliates, or any person or entity acting on behalf of the Investor or any of its controlled affiliates or pursuant to any understanding with the Investor or any of its controlled affiliates will engage in any Short Sales with respect to securities of KVSB prior to the Closing.

Annex E-xv

10. Trust Account Waiver.The Investor acknowledges that KVSB is a blank check company with the powers and privileges to effect a merger, asset acquisition, reorganization or similar business combination involving KVSB and one or more businesses or assets. The Investor further acknowledges that, as described in KVSB's prospectus relating to its initial public offering dated March 23, 2021 (the 'Prospectus') available at www.sec.gov, substantially all of KVSB's assets consist of the cash proceeds of KVSB's initial public offering and private placement of its securities, and substantially all of those proceeds have been deposited in a trust account (the 'Trust Account') for the benefit of KVSB, its public stockholders and the underwriter of KVSB's initial public offering. Except with respect to interest earned on the funds held in the Trust Account that may be released to KVSB to pay its tax obligations, if any, the cash in the Trust Account may be disbursed only for the purposes set forth in the Prospectus. For and in consideration of KVSB entering into this Subscription Agreement, the receipt and sufficiency of which are hereby acknowledged, the Investor hereby irrevocably waives any and all right, title and interest, or any claim of any kind it has or may have in the future, in or to any monies held in the Trust Account, as a result of, in connection with or relating in any way to, this Subscription Agreement, regardless of whether such claim arises based on contract, tort, equity or any other theory of legal liability, and irrevocably agrees not to seek recourse against the Trust Account as a result of, or arising out of, this Subscription Agreement; provided however,that nothing in this Section 10shall serve to limit or prohibit the Investor's right to pursue a claim against KVSB for legal relief against assets held outside the Trust Account, for specific performance or other equitable relief. The Investor agrees and acknowledges that such irrevocable waiver is material to this Subscription Agreement and specifically relied upon by KVSB and its affiliates to induce KVSB to enter in this Subscription Agreement, and each such party further intends and understands such waiver to be valid, binding and enforceable against the Investor and its affiliates under applicable law. To the extent the Investor commences any action or proceeding based upon, in connection with, relating to or arising out of any matter relating to KVSB or its affiliates, which proceeding seeks, in whole or in part, monetary relief against KVSB or its affiliates, the Investor hereby acknowledges and agrees that the Investor's sole remedy shall be against funds held outside of the Trust Account and that such claim shall not permit the Investor (or any person claiming on its behalf or in lieu of the Investor) to have any claim against the Trust Account (including any distributions therefrom) or any amounts contained therein. Notwithstanding anything else in this Section 10to the contrary, nothing herein shall be deemed to waive or limit the Investor or its affiliates' right, title, interest or claim to the Trust Account by virtue of the Investor's record or beneficial ownership of Shares or other equity interests of KVSB acquired by any means other than pursuant to this Subscription Agreement, including but not limited to any redemption right with respect to any such securities of KVSB.

Such Shelf shall provide for the resale of the Registrable Securities included therein pursuant to any method or combination of methods legally available to, and requested by, any Holder named therein. The Company shall maintain a Shelf in accordance with the terms hereof, and shall prepare and file with the Commission such amendments, including post-effective amendments, and supplements as may be necessary to keep a Shelf continuously effective, available for use to permit the Holders named therein to sell their Registrable Securities included therein and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities. In the event the Company files a Form S-1 Shelf, the Company shall use its commercially reasonable efforts to convert the Form S-1 Shelf (and any Subsequent Shelf Registration Statement) to a Form S-3 Shelf as soon as practicable after the Company is eligible to use a Form S-3 Shelf. The Company's obligation under this Section 2.1.1, shall, for the avoidance of doubt, be subject to Section 3.4.

2.1.2 Subsequent Shelf Registration. If any Shelf ceases to be effective under the Securities Act for any reason at any time while Registrable Securities are still outstanding, the Company shall, subject to Section 3.4, use its commercially reasonable efforts to as promptly as is reasonably practicable cause such Shelf to again become effective under the Securities Act (including using its commercially reasonable efforts to obtain the prompt withdrawal of any order suspending the effectiveness of such Shelf), and shall use its commercially reasonable efforts to as promptly as is reasonably practicable amend such Shelf in a manner reasonably expected to result in the withdrawal of any order suspending the effectiveness of such Shelf or file an additional registration statement as a Shelf Registration (a 'Subsequent Shelf Registration Statement') registering the resale of all Registrable Securities (determined as of two (2) business days prior to such filing). If a Subsequent Shelf Registration Statement is filed, the Company shall use its commercially reasonable efforts to (i) cause such Subsequent Shelf Registration Statement to become effective under the Securities Act as promptly as is reasonably

Annex F-v

practicable after the filing thereof (it being agreed that the Subsequent Shelf Registration Statement shall be an automatic shelf registration statement (as defined in Rule 405 promulgated under the Securities Act) if the Company is a well-known seasoned issuer (as defined in Rule 405 promulgated under the Securities Act) at the most recent applicable eligibility determination date) and (ii) keep such Subsequent Shelf Registration Statement continuously effective, available for use to permit the Holders named therein to sell their Registrable Securities included therein and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities.

The Company's obligation under this Section 2.1.2, shall, for the avoidance of doubt, be subject to Section 3.4.

2.1.3 Additional Registrable Securities. Subject to Section 3.4, in the event that any Holder holds Registrable Securities that are not registered for resale on a delayed or continuous basis, the Company, upon written request of such Holder, shall promptly use its commercially reasonable efforts to cause the resale of such Registrable Securities to be covered by either, at the Company's option, any then available Shelf (including by means of a post-effective amendment) or by filing a Subsequent Shelf Registration Statement and cause the same to become effective as soon as reasonably practicable after such filing and such Shelf or Subsequent Shelf Registration Statement shall be subject to the terms hereof; provided, however, that the Company shall only be required to cause such additional Registrable Securities to be so covered twice per calendar year for each of the Sponsor and the Target Holders.

2.1.4 Requests for Underwritten Shelf Takedowns. Subject to Section 3.4, at any time and from time to time when an effective Shelf is on file with the Commission, the Sponsor or a Target Holder (any of the Sponsor or such Target Holder being in such case, a 'Demanding Holder') may request to sell all or any portion of its Registrable Securities in an Underwritten Offering that is registered pursuant to the Shelf (each, an 'Underwritten Shelf Takedown'); providedthat the Company shall only be obligated to effect an Underwritten Shelf Takedown if such offering shall include Registrable Securities proposed to be sold by the Demanding Holder, either individually or together with other Demanding Holders, with a total offering price of at least, in the aggregate, $100.0 million (the 'Minimum Takedown Threshold'). All requests for Underwritten Shelf Takedowns shall be made by giving written notice to the Company, which shall specify the approximate number of Registrable Securities proposed to be sold in the Underwritten Shelf Takedown. Subject to Section 2.3.4, the Demanding Holder shall have the right to select the Underwriters for such offering (which shall consist of one or more reputable nationally recognized investment banks), subject to the Company's prior approval (which shall not be unreasonably withheld, conditioned or delayed). The Sponsor and the Target Holders may each demand not more than (i) one (1) Underwritten Shelf Takedown pursuant to this Section 2.1.4within any six (6) month period, (ii) two (2) Underwritten Shelf Takedowns pursuant to this Section 2.1.4in any twelve (12) month period or (iii) three (3) Underwritten Shelf Takedowns in the aggregate on Form S-1 or any similar long-form registration statement.

2.1.5 Reduction of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Shelf Takedown, in good faith, advises the Company, the Demanding Holders and the Holders requesting piggy-back rights pursuant to this Agreement with respect to such Underwritten Shelf Takedown (the 'Requesting Holders') (if any) in writing that the dollar amount or number of Registrable Securities that the Demanding Holders and the Requesting Holders (if any) desire to sell, taken together with all other shares of Common Stock or other equity securities that the Company desires to sell and all other shares of Common Stock or other equity securities, if any, that have been requested to be sold in such Underwritten Offering pursuant to separate written contractual piggy-back registration rights held by any other stockholders of the Company, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of such securities, as applicable, the 'Maximum Number of Securities'), then the Company shall include in such Underwritten Offering, before including any shares of Common Stock or other equity securities proposed to be sold by Company or by other holders of Common Stock or other equity securities, the Registrable Securities of (i) first, the Demanding Holders

If withdrawn, a demand for an Underwritten Shelf Takedown shall constitute a demand for an Underwritten Shelf Takedown by the withdrawing Demanding Holder for purposes of Section 2.1.4, unless such Demanding Holder reimburses the Company for all Registration Expenses with respect to such Underwritten Shelf Takedown (or, if there is more than one Demanding Holder, a pro rata portion of such Registration Expenses based on the respective number of Registrable Securities that each Demanding Holder has requested be included in such Underwritten Shelf Takedown); providedthat, if the Sponsor or a Target Holder elects to continue an Underwritten Shelf Takedown pursuant to the proviso in the immediately preceding sentence, such Underwritten Shelf Takedown shall instead count as an Underwritten Shelf Takedown demanded by the Sponsor or such Target Holder, as applicable, for purposes of Section 2.1.4. Following the receipt of any Withdrawal Notice, the Company shall reasonably promptly forward such Withdrawal Notice to any other Holders that had elected to participate in such Shelf Takedown.

3.1.1 prepare and file with the Commission as soon as practicable a Registration Statement with respect to such Registrable Securities and use its commercially reasonable efforts to cause such Registration Statement to become effective and remain effective until all Registrable Securities covered by such Registration Statement are sold in accordance with the intended plan of distribution set forth in such Registration Statement or have ceased to be Registrable Securities;

3.1.2 prepare and file with the Commission such amendments and post-effective amendments to the Registration Statement, and such supplements to the Prospectus, as may be reasonably requested by any Holder that, together with such Holder's Permitted Transferees, holds at least five percent (5%) of the Registrable Securities registered on such Registration Statement or any Underwriter of Registrable Securities or as may be required by the rules, regulations or instructions applicable to the registration form used by the Company or by the Securities Act to keep the Registration Statement effective until all Registrable Securities covered by such Registration Statement are sold in accordance with the intended plan of distribution set forth in such Registration Statement or supplement to the Prospectus or have ceased to be Registrable Securities;

3.1.3 prior to filing a Registration Statement or Prospectus, or any amendment or supplement thereto, furnish without charge to the Underwriters, if any, and the Holders of Registrable Securities included in such Registration, and such Holders' legal counsel, copies of such Registration Statement as proposed to be filed, each amendment and supplement to such Registration Statement (in each case including all exhibits thereto and documents incorporated by reference therein), the Prospectus included in such Registration Statement (including each preliminary Prospectus), and such other documents as the Underwriters and the Holders of Registrable Securities included in such Registration or the legal counsel for any such Holders may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Holders; providedthat the Company shall have no obligation to furnish any documents publicly filed or furnished with the Commission pursuant to the Electronic Data Gathering, Analysis and Retrieval System ('EDGAR');

3.1.4 prior to any public offering of Registrable Securities, use its commercially reasonable efforts to (i) register or qualify the Registrable Securities covered by the Registration Statement under such securities or 'blue sky' laws of such jurisdictions in the United States as the Holders of Registrable Securities included in such Registration Statement (in light of their intended plan of distribution) may request (or provide evidence satisfactory to such Holders that the Registrable Securities are exempt from such registration or qualification) and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement to be registered with or approved by such other governmental authorities as may be necessary by virtue of the business and operations of the Company and do any and all other acts and things that may be necessary or advisable to enable the Holders of Registrable Securities included in such Registration Statement to consummate the disposition of such Registrable Securities in such jurisdictions; provided, however, that the Company shall not be

3.1.8 at least five (5) days prior to the filing of any Registration Statement or Prospectus or any amendment or supplement to such Registration Statement or Prospectus (or such shorter period of time as may be (a) necessary in order to comply with the Securities Act or the Exchange Act, as applicable or (b) advisable in order to reduce the number of days that sales are suspended pursuant to Section 3.4), furnish a copy thereof to each seller of such Registrable Securities or its counsel (excluding any exhibits thereto and any filing made under the Exchange Act that is to be incorporated by reference therein);

3.1.11 obtain a 'comfort' letter from the Company's independent registered public accountants in the event of an Underwritten Offering, a Block Trade, an Other Coordinated Offering or sale by a broker, placement agent or sales agent pursuant to such Registration (subject to such broker, placement agent or sales agent providing such certification or representation reasonably requested by the Company's independent registered public accountants and the Company's counsel) in customary form and covering such matters of the type customarily covered by 'comfort' letters for a transaction of its type as the managing Underwriter may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating Holders;

3.1.12 in the event of an Underwritten Offering, a Block Trade, an Other Coordinated Offering or sale by a broker, placement agent or sales agent pursuant to such Registration, on the date the Registrable Securities are delivered for sale pursuant to such Registration, to the extent customary for a transaction of its type, obtain an opinion, dated such date, of counsel representing the Company for the purposes of such Registration, addressed to the participating Holders, the broker, placement agents or sales agent, if any, and the Underwriters, if any, covering such legal matters with respect to the Registration in respect of which such opinion is being given as the participating Holders, broker, placement agent, sales agent or Underwriter may reasonably request and as are customarily included in such opinions and negative assurance letters;

Annex F-xi

3.1.13 in the event of any Underwritten Offering, a Block Trade, an Other Coordinated Offering or sale by a broker, placement agent or sales agent pursuant to such Registration, enter into and perform its obligations under an underwriting or other purchase or sales agreement, in usual and customary form, with the managing Underwriter or the broker, placement agent or sales agent of such offering or sale;

3.1.14 make available to its security holders, as soon as reasonably practicable, an earnings statement (which need not be audited) covering the period of at least twelve (12) months beginning with the first day of the Company's first full calendar quarter after the effective date of the Registration Statement which satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any successor rule then in effect);

3.1.15 with respect to an Underwritten Offering pursuant to Section 2.1.4, use its commercially reasonable efforts to make available senior executives of the Company to participate in customary 'roadshow' presentations that may be reasonably requested by the Underwriter in such Underwritten Offering; and

3.1.16 otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the participating Holders, consistent with the terms of this Agreement, in connection with such Registration.

Notwithstanding the foregoing, the Company shall not be required to provide any documents or information to an Underwriter, broker, sales agent or placement agent if such Underwriter, broker, sales agent or placement agent has not then been named with respect to the applicable Underwritten Offering or other offering involving a Registration as an Underwriter, broker, sales agent or placement agent, as applicable.

3.2 Registration Expenses. The Registration Expenses of all Registrations shall be borne by the Company. It is acknowledged by the Holders that the Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters' commissions and discounts, brokerage fees, Underwriter marketing costs and, other than as set forth in the definition of 'Registration Expenses,' all reasonable fees and expenses of any legal counsel representing the Holders.

3.3 Requirements for Participation in Registration Statement in Offerings. Notwithstanding anything in this Agreement to the contrary, if any Holder does not provide the Company with its requested Holder Information, the Company may exclude such Holder's Registrable Securities from the applicable Registration Statement or Prospectus if the Company determines, based on the advice of counsel, that it is necessary or advisable to include such information in the applicable Registration Statement or Prospectus and such Holder continues thereafter to withhold such information. In addition, no person or entity may participate in any Underwritten Offering or other offering for equity securities of the Company pursuant to a Registration initiated by the Company hereunder unless such person or entity (i) agrees to sell such person's or entity's securities on the basis provided in any underwriting, sales, distribution or placement arrangements approved by the Company and (ii) completes and executes all customary questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting or other agreements and other customary documents as may be reasonably required under the terms of such underwriting, sales, distribution or placement arrangements. For the avoidance of doubt, the exclusion of a Holder's Registrable Securities as a result of this Section 3.3shall not affect the registration of the other Registrable Securities to be included in such Registration.

3.4 Suspension of Sales; Adverse Disclosure; Restrictions on Registration Rights.

3.4.1 (a) Upon receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement; (b) upon written notice from the Company that the Commission has requested an amendment or supplement to a Registration Statement or Prospectus or additional information, or an event has occurred that requires the preparation of a supplement or amendment to such Prospectus so that, as thereafter delivered to the purchasers of the securities covered by such Registration Statement or Prospectus, such Registration Statement or Prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading; or (c) if the Company has, pursuant to a written insider trading compliance program adopted by the Board with respect to 'insiders' including the relevant Holder, suspended transactions in the Company's securities, each of the Holders (in the case of (a) and (b)) or the relevant Holder(s) (in the case of (c)) shall forthwith discontinue disposition of Registrable Securities

Annex F-xii

pursuant to such Registration Statement covering such Registrable Securities until it has received copies of a supplemented or amended Prospectus (it being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as reasonably practicable after the time of such notice) or until such Holder is advised in writing by the Company that the use of the Prospectus may be resumed (in the case of (a) or (b)), or until the restriction on the ability of 'insiders' to transact in the Company's securities is removed (in the case of (c)).

3.4.2 Subject to Section 3.4.4, if the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time would (a) require the Company to make an Adverse Disclosure, (b) require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company's control, or (c) in the good faith judgment of the majority of the Board, be materially detrimental to the Company and the majority of the Board concludes as a result that it is essential to defer such filing, initial effectiveness or continued use at such time, the Company may, upon giving prompt written notice of such action to the Holders (which notice shall not specify the nature of the event giving rise to such delay or suspension), delay the filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest period of time determined in good faith by the Company to be necessary for such purpose. In the event the Company exercises its rights under this Section 3.4.2, the Holders agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable Securities until such Holder receives written notice from the Company that such sales or offers of Registrable Securities may be resumed, and in each case maintain the confidentiality of such notice and its contents.

3.4.3 Subject to Section 3.4.4, (a) during the period starting with the date sixty (60) days prior to the Company's good faith estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective date of, a Company-initiated Registration and provided that the Company continues to actively employ, in good faith, all commercially reasonable efforts to maintain the effectiveness of the applicable Shelf Registration Statement, or (b) if, pursuant to Section 2.1.4, Holders have requested an Underwritten Shelf Takedown and the Company and Holders are unable to obtain the commitment of underwriters to firmly underwrite such offering, the Company may, upon giving prompt written notice of such action to the Holders, delay any other registered offering pursuant to Section 2.1.4or 2.4.

3.4.4 The right to delay or suspend any filing, initial effectiveness or continued use of a Registration Statement pursuant to Section 3.4.2or a registered offering pursuant to Section 3.4.3shall be exercised by the Company, in the aggregate, for not more than ninety (90) consecutive calendar days or more than ninety (90) total calendar days in each case, during any twelve (12)-month period.

3.5 Reporting Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be a reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings; providedthat any documents publicly filed or furnished with the Commission pursuant to EDGAR shall be deemed to have been furnished or delivered to the Holders pursuant to this Section 3.5. The Company further covenants that it shall take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell shares of Common Stock held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule then in effect). Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements.

ARTICLE IV

INDEMNIFICATION AND CONTRIBUTION

4.1 Indemnification.

4.1.1 The Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its partners, shareholders, members, managers, officers, directors, employees and agents and

Annex F-xiii

each person or entity who controls such Holder (within the meaning of the Securities Act), against all losses, claims, damages, liabilities and out-of-pocket expenses (including, without limitation, reasonable and documented outside attorneys' fees) resulting from any untrue or alleged untrue statement of material fact contained in or incorporated by reference in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information or affidavit so furnished in writing to the Company by such Holder expressly for use therein. The Company shall indemnify the Underwriters, their officers and directors and each person or entity who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to the indemnification of the Holder.

4.1.2 In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish (or cause to be furnished) to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus (the 'Holder Information') and, to the extent permitted by law, shall indemnify the Company, its directors, officers and agents and each person or entity who controls the Company (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and out-of-pocket expenses (including, without limitation, reasonable and documented outside attorneys' fees) resulting from any untrue or alleged untrue statement of material fact contained or incorporated by reference in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement is contained in (or not contained in, in the case of an omission) any information or affidavit so furnished in writing by or on behalf of such Holder expressly for use therein; provided, however, that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify the Underwriters, their officers, directors and each person or entity who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company.

4.1.3 Any person or entity entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person's or entity's right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) unless in such indemnified party's reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its written consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the written consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement includes a statement or admission of fault and culpability on the part of such indemnified party or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

4.1.4 The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person or entity of such indemnified party and shall survive the transfer of securities.

4.1.5 If the indemnification provided under Section 4.1from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities

Annex F-xiv

and out-of-pocket expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and out-of-pocket expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by (or not made by, in the case of an omission), or relates to information supplied by (or not supplied by in the case of an omission), such indemnifying party or indemnified party, and the indemnifying party's and indemnified party's relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that the liability of any Holder under this Section 4.1.5shall be limited to the amount of the net proceeds received by such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in Sections 4.1.1, 4.1.2and 4.1.3above, any legal or other fees, charges or out-of-pocket expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.1.5were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred to in this Section 4.1.5. No person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 4.1.5from any person or entity who was not guilty of such fraudulent misrepresentation.

Upon the execution and delivery and subject to the terms of a Joinder by such Additional Holder, the Common Stock then owned, or underlying any rights then owned, by such Additional Holder (the 'Additional Holder Common Stock') shall be Registrable Securities to the extent provided herein and therein and such Additional Holder shall be a Holder under this Agreement with respect to such Additional Holder Common Stock.

5.11 Severability. It is the desire and intent of the parties that the provisions of this Agreement be enforced to the fullest extent permissible under the laws and public policies applied in each jurisdiction in which enforcement is sought. Accordingly, if any particular provision of this Agreement shall be adjudicated by a court of competent jurisdiction to be invalid, prohibited or unenforceable for any reason, such provision, as to such jurisdiction, shall be ineffective, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction. Notwithstanding the foregoing, if such provision could be more narrowly drawn so as not to be invalid, prohibited or unenforceable in such jurisdiction, it shall, as to such jurisdiction, be so narrowly drawn, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction.

5.12 Entire Agreement; Restatement. This Agreement constitutes the full and entire agreement and understanding between the parties with respect to the subject matter hereof and supersedes all prior agreements and understandings relating to such subject matter. Upon the Closing, the Original RRA shall no longer be of any force or effect.

If, and as often as, there are any changes in the Registrable Securities by way of stock split, stock dividend, combination or reclassification, or through merger, consolidation, reorganization, recapitalization or sale, or by any other means, appropriate adjustment shall be made in the provisions of this Agreement, as may be required, so that the rights, privileges, duties and obligations hereunder shall continue with respect to the Registrable Securities as so changed.
