PRELIMINARY PROXY MATERIALS - SUBJECT TO COMPLETION, DATED JULY 17, 2023
What constitutes a quorum?
The holders of one-third of the proposals in this proxy statement,voting power of the electionshares of director nominees is a non-routine matter,our common stock issued and the appointment of an independent registered public accounting firm is a routine matter. A “broker non-vote” refers to a share represented at the meeting held by a broker, as to which instructions have not been received from the beneficial owner or personoutstanding and entitled to vote, such shares and with respect to which, on onein person or more but not all matters, the broker does not have discretionary voting power to vote such share.

Can I change my vote?

You may revoke yourrepresented by proxy at any time before itthe Special Meeting, constitute a quorum. A quorum is voted by notifyingnecessary to transact business at the Company’s Corporate Secretary in writing, by returning a signed proxy with a later date, by transmitting a subsequentSpecial Meeting.

What is the required vote overto approve the internet or by telephone prior toproposals?
Under Delaware law, the closeaffirmative vote of the internet voting facility or the telephone voting facility. You may also attend the virtual meeting and vote during the meeting. If your stock is held in street name, you must contact your broker or nominee for instructions as to how to change your vote.

How is a quorum reached?

The presence, by virtual attendance or by proxy, of holders of at least a majority of the total numbervoting power of the outstanding shares of our Class A common stock entitled to vote at the Special Meeting is necessaryrequired to constituteauthorize our Board to amend our Second Amended and Restated Certificate of Incorporation to effect the Reverse Stock Split.

The affirmative vote of a majority of the voting power of the shares of our Class A common stock present in person or represented by proxy at the Special Meeting is required to approve the Adjournment Proposal.
The Delaware General Assembly has passed amendments to the Delaware General Corporation Law (the “DGCL”) that would change the stockholder vote required to effect a reverse split of stock that is listed on a national securities exchange and meets certain other requirements. The DGCL amendments are anticipated to become effective on August 1, 2023, if they are signed into law by the Governor of Delaware, or otherwise enacted pursuant to Delaware law, on or before that date. If the amendments to the DGCL become effective before Momentus files the amendment to the Second Amended and Restated Certificate of Incorporation of Momentus with the Delaware Secretary of State to effect the Reverse Stock Split, the Board reserves the right to rely upon the new stockholder vote requirements authorized by the DGCL amendments to determine if Proposal No. 1 has been adopted. The DGCL amendments would permit Momentus to effect the Reverse Stock Split if the votes cast “FOR” Proposal No. 1 exceed the votes cast “AGAINST” Proposal No. 1, assuming the presence of a quorum and if the shares of Class A common stock meet the listing requirement of the national securities exchange on which they are listed immediately after the amendment to the Second Amended and Restated Certificate of Incorporation effecting the Reverse Stock Split becomes effective. Under this voting standard, abstentions and broker non-votes (if any), and shares of Class A common stock that are not present in person or by proxy at the Special Meeting, will have no effect on the outcome of the vote on Proposal No. 1.
What is the effect of abstentions and broker non-votes?
Abstentions and broker non-votes will be treated as shares present for the purpose of determining the presence of a quorum for the transaction of business at the AnnualSpecial Meeting. Shares held of record by stockholders or brokers, bankers or other nominees who do not return a signed and dated proxy or attend the Annual Meeting virtually will not be considered present or represented at the Annual Meeting and will not be counted in determining the presence of a quorum. Abstentions and broker non-votes, if any, will be counted for purposes of determining whether a quorum is present for the transaction of business at the meeting.

What vote is required to approve each item and how are votes counted?

Votes cast by proxy or online at the Annual Meeting will be counted by the persons appointed by the Company to act as tabulators for the meeting. The tabulators will count all votes FOR, AGAINST, abstentions and broker non-votes, as applicable, for each matter to be voted on at the Annual Meeting. Abstentions and broker non-votes are not counted as votes cast and, therefore, do not have the effect of votes in opposition to such proposals. A broker non-vote occurs when a bank, broker or other nominee holding shares for a beneficial owner does not votesubmits a proxy for the Special Meeting without voting on a particular proposal, because the bank, broker or other nominee has not received instructions from the beneficial owner and does not have discretionary voting power with respect to that item and has not received instructions from theproposal. If you are a beneficial owner.

Proposal 1—Electionowner of two Class II director nominees

The two nominees for director to receive the highest number of votes FOR election will be elected as directors. This is called a plurality. Proposal 1 is a non-routine matter. Therefore, if your shares are held by your brokerage firm in street name and you do not timely provide voting instructionsinstruct your broker how to vote your shares, the question of whether your broker will still be able to vote your shares depends on whether the New York Stock Exchange (the “NYSE”) deems the particular proposal to be a “routine” matter. Although our shares of Class A common stock are listed with Nasdaq, the NYSE regulates broker-dealers and their discretion to vote on stockholder proposals. Under the NYSE rules applicable to brokers and other similar organizations that are subject to NYSE rules, such organizations may use their discretion to vote your “uninstructed shares” with respect to matters considered to be “routine” under NYSE rules, but not with respect to “non-routine” matters. Under such rules and interpretations, non-routine matters are matters that may substantially affect the rights or privileges of stockholders, such as mergers, stockholder proposals, elections of directors (even if not contested), executive compensation (including any advisory stockholder votes on executive compensation), and certain corporate governance proposals, even if management-supported. We understand the proposal to authorize the Board to amend the Second Amended and Restated Certificate of Incorporation to effect the Reverse Stock Split and the Adjournment Proposal will be considered “routine” by the NYSE and, accordingly, we believe that your shares, your brokerage firm cannotbroker may vote your shares on Proposal 1. Shares heldsuch proposals without instructions from you. Nevertheless, whether a proposal is “routine” or “non-routine” remains subject to the final determination of the NYSE.

We strongly encourage you to submit your voting instructions to your broker to ensure your shares of common stock are voted in street nameaccordance with your instructions at the Special Meeting.

PRELIMINARY PROXY MATERIALS - SUBJECT TO COMPLETION, DATED JULY 17, 2023
Because adoption and approval of the amendment to our Second Amended and Restated Certificate of Incorporation to effect the Reverse Stock Split requires a majority of the voting power of the outstanding shares of Class A common stock, an abstention with respect to the Reverse Stock Split proposal will have the same effect as a vote “Against” the proposal; however, in the event that recent amendments to the DGCL approved by banks, brokerage firms or other nominees who indicate on their proxies that they do not have authority to vote the shares on Proposal 1 will not be counted as votes FOR or WITHHELD from any nominee. As a result, such “broker non-votes”Delaware General Assembly go into effect, abstentions will have no effect on the votingoutcome of the vote on Proposal No. 1. You may:

vote FOR all nominees;

vote FOR one or more nominees and WITHHOLD from other nominees; or

WITHHOLD your vote from all nominees.

Votes that are withheld will not be included inSee “What is the required vote tally for the election of the director.

Proposal 2—Ratification of the selection of Armanino LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2023

To approve Proposal 2, holders of a majority of the votes cast on the matter must vote FOR the proposal. For the ratification of the selection of Armanino LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2023, the votes cast FOR must exceed the votes cast AGAINST. Only FOR and AGAINST votes will affect the outcome. Abstentions will have no effect on the voting of Proposal 2. Proposal 2 is a routine matter. Therefore, if your shares are held by your bank, broker or other nominee in street name and you do not vote your shares, your bank, broker or other nominee may vote your shares on Proposal 2.

If there are insufficient votes to approve Proposals 1 or 2, your proxy may be voted by the persons named in the proxy to adjourn the Annual Meeting in order to solicit additional proxies in favor of the approval of such proposal. If the Annual Meeting is adjourned or postponed for any purpose, at any subsequent reconvening of the meeting, your proxy will be voted in the same manner as it would have been voted at the original convening of the Annual Meeting unless you withdraw or revoke your proxy. Your proxy may be voted in this manner even though it may have been voted on the same or any other matter at a previous session of the Annual Meeting.

Could other matters be decided at the Annual Meeting?

The Company does not know of any other matters that may be presented for action at the Annual Meeting.

This practice, referred to as “householding,” benefits both you and the Company. It reduces the volume of duplicate information received at your household and helps to reduce our periodicexpenses.

Corporate Governance

Director Composition

As illustrated by the director biographies on the previous pages, our board is made up of a diverse group of leaders with substantial experience in their respective fields. We believe that diversity in our board’s composition, skills, qualifications and experiences contributes to an effective and well-functioning board. As such, we believe that the board possesses the necessary qualifications to provide effective oversight and insightful strategic guidance for the Company.

We regularly review our board’s composition to identify the skills needed for our Company both in the near term and into the future. We highly value diversity in composition, experience and skills in evaluating and recommending new directors for our board. Ongoing strategic board succession planning assures that the board continues to maintain an appropriate mix of objectivity, skills and experiences to provide fresh perspectives and effective oversight and guidance to management, while leveraging the institutional knowledge and historical perspective of more experienced directors.

Director Independence

Each of the directors on the Board of Directors, other than John C. Rood, qualifies as an independent director, as defined under Nasdaq listing rules, and the board consists of a majority of “independent directors,” as defined under the rules of the SEC and Nasdaq listing rules relating to director independence requirements. In addition, we are subject to the rulesfull text of the SECproposed amendment, which is attached to this Proxy Statement as Annex A.

If stockholders approve this proposal, the Board will cause the Certificate of Amendment to be filed with the Delaware Secretary of State and Nasdaq relatingeffect the Reverse Stock Split only if the Board determines that the Reverse Stock Split would be in the best interests of Momentus and its stockholders at that time. The Reverse Stock Split could become effective as soon as the business day immediately following the Special Meeting. The Board also may determine in its discretion not to effect the Reverse Stock Split and not to file the Certificate of Amendment. No further action on the part of stockholders will be required for the Board to either implement or abandon the Reverse Stock Split.
The proposed amendment, if effected, will effect a Reverse Stock Split of the outstanding shares of Momentus’ common stock at a reverse stock split ratio in the range of 1-for-[•] through 1-for-[•] (the “Ratio Range”), as determined by our Board at a later date. As of the Record Date, [•] shares of our Class A common stock were issued and outstanding. Based on such number of shares of our common stock issued and outstanding, immediately following the effectiveness of the Reverse Stock Split (and without giving effect to rounding for fractional shares), we will have, depending on the reverse stock split ratio selected by our Board, issued and outstanding shares of common stock as illustrated in the table under the caption “—Effects of the Reverse Stock Split—Effect on Shares of Class A Common Stock.” All holders of Momentus’ Class A common stock will be affected proportionately by the Reverse Stock Split.
We will not issue any fractional shares as a result of the Reverse Stock Split and in lieu thereof any stockholders that would otherwise be entitled to receive a fractional share will be entitled to have their post-Reverse Stock Split share amount rounded up to the membership, qualifications and operationsnearest whole share (which we describe below). Each stockholder will hold the same percentage of common stock immediately following the Reverse Stock Split as such stockholder held immediately prior to the Reverse Stock Split other than the nominal effect of the Audit Committee, as discussed below.

treatment of fractional shares. The par value of our Class A common stock will continue to be $0.00001 per share (see “—Effects of the Reverse Stock Ownership Guidelines

TheSplit—Reduction in Stated Capital”).

Reasons for the Reverse Stock Split
Reverse Stock Split
Our Board of Directors believeshas determined that it is in the best interests of Momentus and its stockholders to combine our shares of common stock within a range of 1-for-[•] through 1-for-[•], as determined by the Board at a later date, in order to raise the per share trading price of our Class A common stock. Our Class A common stock is publicly traded and listed on the Nasdaq Stock Market LLC (“Nasdaq”) under the symbol “MNTS.”
On March 22, 2023, we received a written notice (the “Nasdaq Notice”) from Nasdaq notifying us that, for the prior 30 consecutive business days, the bid price for the Company’s Class A common stock had closed below the $1.00 per share minimum bid price requirement for continued inclusion on The Nasdaq Global Select Market pursuant to Nasdaq Listing Rule 5450(a)(1) (the “Minimum Bid Price Requirement”). The Nasdaq Notice had no immediate effect on the listing of the Class A common stock, which continues to trade on The Nasdaq Global Select Market.
In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company has a period of 180 calendar days, or until September 18, 2023, to regain compliance with the Minimum Bid Price Requirement. To regain
7

PRELIMINARY PROXY MATERIALS - SUBJECT TO COMPLETION, DATED JULY 17, 2023
compliance, the closing bid price of the Company’s Class A common stock must be at least $1.00 per share for a minimum of 10 consecutive business days as required under Nasdaq Listing Rule 5810(c)(3)(A) (unless the Nasdaq staff exercises its discretion to extend this 10-day period pursuant to Nasdaq Listing Rule 5810(c)(3)(H)) during the 180-day period prior to September 18, 2023.
If the Company does not regain compliance by September 18, 2023, the Company may be eligible for an additional 180-calendar day compliance period if it elects (and meets the listing standards) to transfer to The Nasdaq Capital Market to take advantage of the additional compliance period offered on that market. To qualify, the Company would be required, among other things, to meet the continued listing requirement for market value of publicly held shares as well as all other standards for initial listing on The Nasdaq Capital Market, with the exception of the bid price requirement, and would need to provide written notice of its intention to cure the bid price deficiency during the second compliance period. If the Company fails to regain compliance during the compliance period (including a second compliance period provided by a transfer to The Nasdaq Capital Market, if applicable), then Nasdaq will notify the Company of its determination to delist the Company’s Class A common stock, at which point the Company may appeal Nasdaq’s delisting determination to a Nasdaq hearing panel. Accordingly, the Company believes that effecting the Reverse Stock Split will be in Momentus’ and our stockholders’ best interests.
Additionally, the Company believes that an increased stock price may encourage investor interest and improve the marketability of our Class A common stock to a broader range of investors. Because of the trading volatility often associated with low-priced stocks, many brokerage firms and institutional investors have internal policies and practices that either prohibit them from investing in low-priced stocks or tend to discourage individual brokers from recommending low-priced stocks to their customers. The closing sale price of our Class A common stock on [•], 2023, was $[•] per share. The Company believes that the anticipated higher market price resulting from a reverse stock split would enable institutional investors and brokerage firms with policies and practices such as those described above to invest in our Class A common stock.
We believe that maintaining our listing on Nasdaq will provide us with a market for the Class A common stock that is more accessible than if our Class A common stock were traded on the OTC Bulletin Board or in the “pink sheets” maintained by the OTC Markets Group, Inc. Such alternative markets are generally considered to be less efficient than, and not as broad as, Nasdaq. Among other factors, trading on Nasdaq increases liquidity and may potentially minimize the spread between the “bid” and “asked” prices quoted by Market Makers (as defined in Nasdaq Rule 5005). We believe that prospective investors will view an investment in us more favorably if our Class A common stock qualifies for listing on Nasdaq as compared with the OTC markets.
Reducing the number of outstanding shares of our common stock through the Reverse Stock Split is intended, absent other factors, to increase the per share trading price of our Class A common stock. However, other factors, such as our financial results, market conditions and the market perception of our business may adversely affect the per share trading price of our Class A common stock. As a result, there can be no assurance that the Reverse Stock Split, if completed, will result in the intended benefits described above, that the per share trading price of our Class A common stock will increase following the Reverse Stock Split or that the per share trading price of our Class A common stock will not decrease in the future.
The purpose of seeking stockholder approval of exchange ratios within the Ratio Range (rather than a fixed exchange ratio) is to provide the Company and its shareholders that directors and executive officers have a meaningful proprietary stake in the Company so that their interests are alignedBoard with the interests of shareholders. Accordingly, the board has adopted Stock Ownership Guidelines applicable to our non-employee directors and our executive officers. Our Stock Ownership Guidelines are administered by the Compensation Committee.

11

Under our Stock Ownership Guidelines, nonemployee directors, the Chief Executive Officer and all other executive officers of the Company are expected to hold stock in accordance with the below table.

Board MembersFive times the individual’s annual cash retainer (not including any chair, lead independent director, committee or committee chair service retainers)
Chief Executive OfficerFive times the individual’s annual base salary
All Other Executive OfficersThree times the individual’s annual base salary

Under our Stock Ownership Guidelines, each director and officer is requiredflexibility to achieve the applicable stock ownership level within five years of first becoming subject to the Stock Ownership Guidelines. If an individual becomes subject to a greater ownership amount due to promotion or an increase in base salary, such individual is expected to meet the higher ownership amount within the laterdesired results of the original period or three years fromReverse Stock Split. If our stockholders approve this proposal, then the effective date of such promotion or increaseBoard, in base salary.

Hedging Prohibitions

Our Insider Trading Policy prohibits our directors, officers, employees or designated contractors from purchasing any financial instruments, including variable forward contracts, equity swaps, collars or exchange funds, or otherwise engaging in any transactionsits sole discretion, would effect the Reverse Stock Split only upon the determination by the Board that hedge or offset any decreasea reverse split would be in the market value of the Company’s securities.

Communications with the Board

Any matter intended for the board, or for any individual member of the board, should be directed to Momentus Inc., 3901 N. First Street, San Jose, California 95134, Attention: Corporate Secretary, with a request to forward the communication to the intended recipient. In general, any stockholder communication delivered to the Company for forwarding to board members will be forwarded in accordance with the stockholder’s instructions. The Company reserves the right not to forward to board members any abusive, threatening or otherwise inappropriate materials.

Board Leadership Structure

The board has determined that it should maintain the flexibility to select the Chair of the Board of Directorsbest interests of the Company and adjustour stockholders at that time. See “—Criteria to Be Used for Determining Whether to Implement the Reverse Stock Split.” If the Board were to effect the Reverse Stock Split, then the Board would set the timing for such a split and select the specific ratio within the Ratio Range (the “Final Ratio”). No further action on the part of stockholders would be required for the Board to either implement or abandon the Reverse Stock Split. If our stockholders approve the proposal, and the Board determines to effect the Reverse Stock Split, we would communicate to the public, prior to the Effective Time (as defined below), additional details regarding the Reverse Stock Split, including the Final Ratio selected by the Board. If the Board does not implement the Reverse Stock Split within 12 months

from the Special Meeting, then the authority granted in this proposal to implement the Reverse Stock Split will automatically terminate. If the Board elects not to implement the Reverse Stock Split within this time, stockholder approval would again be required prior to implementing any subsequent reverse stock split. The Board reserves its board leadership structure basedright, notwithstanding stockholder approval and without further action by the stockholders, to elect not to proceed with the Reverse Stock Split at any time prior to the filing of the Certificate of Amendment to the Second Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware.
Criteria to Be Used for Determining Whether to Implement the Reverse Stock Split:
In determining whether to implement the Reverse Stock Split and which reverse stock split ratio to implement, if any, following receipt of stockholder approval authorizing the Board to amend our Second Amended and Restated Certificate of Incorporation to effect the Reverse Stock Split, our Board may consider, among other things, various factors, such as:
a.
the historical trading price and trading volume of our Class A common stock;
b.
Nasdaq continued listing standards requirements;
c.
the then-prevailing trading price and trading volume of our Class A common stock and the expected impact of the Reverse Stock Split on the trading market for our Class A common stock in the short- and long-term; and
d.
prevailing general market and economic conditions.
Certain Risks and Potential Disadvantages Associated with the Reverse Stock Split
We cannot assure you that the proposed Reverse Stock Split will increase our stock price.
We expect that the Reverse Stock Split will increase the per share trading price of our Class A common stock. However, the effect of the Reverse Stock Split on circumstances existing from time to timethe per share trading price of our Class A common stock cannot be predicted with any certainty, and based on criteriathe history of reverse stock splits for other companies is varied, particularly since some investors may view a reverse stock split negatively. It is possible that arethe per share trading price of our Class A common stock after the Reverse Stock Split will not increase in the Company’s best interestssame proportion as the reduction in the number of our outstanding shares of common stock following the Reverse Stock Split, and the best interestsReverse Stock Split may not result in a per share trading price that would attract investors who do not trade in lower priced stocks. In addition, although we believe the Reverse Stock Split may enhance the marketability of our Class A common stock to certain potential investors, we cannot assure stockholders that, if implemented, our Class A common stock will be more attractive to investors. Even if we implement the Reverse Stock Split, the per share trading price of our Class A common stock may decrease due to factors unrelated to the Reverse Stock Split, including our future performance. If the Reverse Stock Split is consummated and the per share trading price of our Class A common stock declines, the percentage decline as an absolute number and as a percentage of our overall market capitalization may be greater than might occur in the absence of the Reverse Stock Split.
The proposed Reverse Stock Split may decrease the liquidity of our Class A common stock and result in higher transaction costs.
The liquidity of our Class A common stock may be negatively impacted by the Reverse Stock Split, given the reduced number of shares that would be outstanding after the Reverse Stock Split, particularly if the per share trading price does not increase as a result of the Reverse Stock Split. In addition, if the Reverse Stock Split is implemented, it will increase the number of our stockholders includingwho own “odd lots” of fewer than 100 shares of common stock. Brokerage commission and other costs of transactions in odd lots are generally higher than the composition, skills, diversitycosts of transactions of more than 100 shares of common stock. Accordingly, the Reverse Stock Split may not achieve the desired results of increasing marketability of our Class A common stock as described above.

The Reverse Stock Split may lead to a decrease in our overall market capitalization.
The Reverse Stock Split may be viewed negatively by the market and, experienceconsequently, could lead to a decrease in our overall market capitalization. If the per share market price of our Class A common stock does not increase in proportion to the Final Ratio, or following such increase does not maintain or exceed that price, then the value of our Company, as measured by our market capitalization, will be reduced. Additionally, any reduction in our market capitalization may be magnified as a result of the boardsmaller number of total shares of Class A common stock outstanding following the Reverse Stock Split.
Effective Time
The effective time of the Reverse Stock Split (the “Effective Time”), if approved by our stockholders and its members, specific challenges facedimplemented by the Company orBoard, will be the industrydate and time set forth in which we operate and governance efficiency.the Certificate of Amendment that is filed with the Delaware Secretary of State.

Security Director

Under our National Security Agreement (the “NSA”),to when such action will be the board must include a director who is approved by the CFIUS Monitoring Agencies. This director, referred to as the “Security Director,” has a fiduciary duty, to the extent consistent with his or her fiduciary dutiesmost advantageous to the Company and our stockholders.

Notwithstanding stockholder approval, and without further action by the stockholders, the Board, in its stockholders under Delaware law,sole discretion, may at any time prior to the U.S. government. The Security Director serves asfiling of the primary liaison betweenCertificate of Amendment with the Delaware Secretary of State, delay or abandon the Reverse Stock Split. If the Board does not implement the Reverse Stock Split within 12 months from the Special Meeting, then the authority granted in this proposal to implement the Reverse Stock Split will automatically terminate. If the Board elects not to implement the Reverse Stock Split within this time, stockholder approval would again be required prior to implementing any subsequent reverse stock split.
Fractional Shares

In lieu of any fractional shares, we will issue to stockholders of record who would otherwise hold a fractional share because the extentnumber of shares of common stock they hold of record before the Reverse Stock Split is not evenly divisible by the Reverse Stock Split ratio that the Security Director believes that a conflictnumber of interest is reasonably likely to exist between her or his fiduciary duties under Delaware lawshares of common stock as rounded up to the Company and/or itsnearest whole share.

Effects of the Security CommitteeReverse Stock Split
General
After the Effective Time of the Board of Directors and has the power to effect the following actions:

In the Security Committee’s sole discretion, remove and replace any officer or employee of the Company;

Review all contracts with customers, third-party vendors and service providers, and all contracts related to certain technical relationships and protected technical information to ensure they comport with the obligations under the NSA; and

In the Security Committee’s sole discretion, block or terminate any contract that the Security Committee determines could reasonably be expected to allow for actions contrary to the NSA, including provisions that the Security Committee determines could reasonably be expected to provide certain parties identified in the NSA with access to protected technical information or could reasonably be expected to cause the transfer of protected technical information in a manner harmful to U.S. national security.

The Security Director is also a member of the Nominating and Corporate Governance Committee. Any individual nominatedReverse Stock Split, if implemented by the Board, each stockholder will own a reduced number of Directorsshares of Class A common stock. The principal effect of the Reverse Stock Split will be to serveproportionately decrease the number of outstanding shares of our Class A common stock based on the Final Ratio selected by our Board.

The Reverse Stock Split would be effected simultaneously for all shares of our common stock, and the Final Ratio would be the same for all shares of our common stock. The Reverse Stock Split would affect all of the holders of our common stock uniformly and would not affect any stockholder’s percentage ownership interests in the Company, voting rights or other rights in each case, other than as a director must be approved by the Security Director. Thus, no person can be nominated to serve as a directorresult of the Company without the approvaltreatment of the Security Director.

In addition to the powers above, the Security Director has the following responsibilities:

Provide timely responses to inquiries from the CFIUS Monitoring Agencies and maintain availability, upon reasonable notice from the CFIUS Monitoring Agencies, for discussions with the CFIUS Monitoring Agencies on matters related to the Company’s governance and compliance with the NSA;

Develop the annual budget for third-party services and other expenses necessary for the Company to perform its obligations under the NSA and the arrangements that set forth the terms for certain parties identified in the NSA relinquishing their ability to direct the voting of interests in the Company;

Review and approve any proposed amendments to the security plan and communications plan required by the NSA, prior to submission of the CFIUS Monitoring Agencies, and any policies and procedures adopted by the Company pursuant thereto, in each case in the Security Director’s sole discretion;

Consult with the CFIUS Monitoring Agencies on nominations to the board and exercise this authority in the Security Director’s sole discretion, subject to such consultation with the CFIUS Monitoring Agencies;

Serve as the primary liaison between the board and the CFIUS Monitoring Agencies and provide timely responses to inquiries from the CFIUS Monitoring Agencies and maintain availability, upon reasonable notice from the CFIUS Monitoring Agencies, for discussions with the CFIUS Monitoring Agencies on matters relating to the Company’s governance and compliance with the NSA; and

Report any actual or potential violation of the NSA to the CFIUS Monitoring Agencies and the third-party monitor within 24 hours of discovery.

Our second amended and restated certificatefractional shares as described herein. For example, a holder of incorporation provides that the Security Director may only be removed for cause and with the approval of the CFIUS Monitoring Agencies and at least two-thirds2% of the voting power of the then outstanding shares of capitalour common stock of the Company entitledimmediately prior to vote generally in the election of directors voting as a single class.

In addition, as required by the NSA, if the Security Director recommends that a director be removed from the board due to an identified national security concern, as determined by the Security Director in consultation with the CFIUS Monitoring Agencies, the board must ask for the resignation of such director. If such director does not resign, the board must call a special meeting of stockholders to vote on the removal of such director. Pending such vote, we are required to ensure that such director does not receive any protected technical information of the Company.

Board Role in Risk Oversight

One of the key functions of the board is informed oversight of the Company’s risk management process. This oversight function is administered directly through the board as a whole, as well as through various standing committees of the board that address risks inherent in their respective areas of oversight. In particular, the board is responsible for monitoring and assessing strategic risk exposure and the Company’s Audit Committee has the responsibility to consider and discuss the Company’s major financial risk exposures and the steps its management will take to monitor and control such exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. The Audit Committee also monitors compliance with legal and regulatory requirements. The Compensation Committee assesses and monitors whether the Company’s compensation plans, policies and programs comply with applicable legal and regulatory requirements. The Nominating and Corporate Governance Committee monitors the effectiveness of Company’s governance guidelines.

Committeesthe Reverse Stock Split will generally continue to hold 2% (other than the nominal effect of the Boardtreatment of Directors

fractional shares) of the voting power of the outstanding shares of our common stock after the Reverse Stock Split. The number of stockholders of record will not be affected by the Reverse Stock Split. If approved and implemented, the Reverse Stock Split may result in additional stockholders owning “odd lots” of less than 100 shares of our Class A common stock. Odd lot shares may be more difficult to sell, and brokerage commissions and other costs of transactions in odd lots are generally somewhat higher than the costs of transactions in “round lots” of even multiples of 100 shares. The Company has an Audit Committee, a Compensation Committeebelieves, however, that these potential effects are outweighed by the benefits of the Reverse Stock Split.

Specifically, it is expected that, among other things, the number of shares of our Class A common stock subject to awards under the Equity Plans will be adjusted in each case to equal the product of the number of shares of our Class A common stock subject to the applicable award immediately prior to the Reverse Stock Split multiplied by the Final Ratio (rounded to the nearest whole share (in the case of stock options, RSUs,down to the nearest whole share)), and other typesthe exercise price of equity awardsany stock option will be adjusted to employees, includingequal the Named Executive Officers.

The Equity Incentive Plan is intended to (i) attract and retainquotient of the best available personnel to ensure our success and accomplish our goals; (ii) incentivize employees, directors and independent contractors with long-term equity-based compensation to align their interests with our stockholders; and (iii) promote the successnumber of shares of our business.

The Equity Incentive Plan permitsClass A common stock subject to the grantapplicable stock option immediately prior to the Reverse Stock Split divided by the Final Ratio (rounded up to the nearest whole cent).

No Going Private Transaction
Notwithstanding the decrease in the number of incentive stock options, nonstatutory stock options, stock appreciation rights (“SARs”), restricted stock, RSUs and stock bonus awards (all such typesoutstanding shares following the proposed Reverse Stock Split, our Board does not intend for this transaction to be the first step in a “going private transaction” within the meaning of awards, collectively, “equity awards”), although incentive stock options may only be granted to employees.

DIRECTOR COMPENSATION

Director Compensation Policy

The Company adopted a non-employee director compensation policy to govern the Board of Directors. The policy is designed to attract and retain high quality non-employee directors by providing competitive compensation and align their interests with the interests of stockholders through equity awards. It will cover the compensation of all roles on the Board of Directors other than the Security Director and the Chairperson of the Security Committee.

Specifically, the policy provides for the following annual cash retainers, which will be payable quarterly in arrears and pro-rated for partial quarters of service:

Annual Board Member Service Retainer

All Outside Directors: $100,000
Outside Director serving as Chairperson: $60,000 (in addition to above)
Outside Director serving as Lead Independent Director: $30,000 (in addition to above)

Annual Committee Member Service Retainer

Member of the Audit Committee: $20,000
Member of the Compensation Committee: $15,000
Member of the Disclosure Committee: $15,000
Member of the Nominating and Corporate Governance Committee: $10,000

Annual Committee Chair Service Retainer (in lieu of Annual Committee Member Service Retainer)

Chairperson of the Audit Committee: $30,000
Chairperson of the Compensation Committee: $22,500
Chairperson of the Disclosure Committee: $22,500
Chairperson of the Nominating and Corporate Governance Committee: $15,000

Equity Compensation

Non-employee directors will receive annual RSU grants under the Equity Incentive Plan on the date of the Company’s Annual Meeting of Stockholders which will vest, subject to continuous service through the applicable vesting date:

RSUs initially valued at $350,000 upon initial election or appointment to board, which will vest in three equal annual installments from the date of grant; and

Additional RSUs initially valued at $250,000 annually, which will vest upon the earlier of the first anniversary of the date of grant or the day before the next annual stockholder meeting, prorated for partial years of service (including the initial year of service).

Transitional Equity Grants

Prior to the 2022 Annual Meeting, in lieu of the RSU grants described above, non-employee directors received transitional RSU grants upon the following terms under the Equity Incentive Plan, which have vested and will vest, subject to continuous service through the applicable vesting date:

Non-employee directors who served after the Closing of the Business Combination (as defined in “Certain Relationships and Related Party Transactions – Support Agreement”) (but before the 2022 Annual Meeting) were granted RSUs initially valued at $350,000, which will vest in three equal annual installments from the date of the Closing.

27

Non-employee directors who served on or after the Closing of the Business Combination were granted RSUs initially valued at $250,000 multiplied by the number of whole months that the non-employee director served from the period beginning on the Closing of the Business Combination and ending on June 1, 2022, divided by 12. Such RSUs vested on May 30, 2022.

Accelerated Vesting

The vesting of the RSU grants will accelerate in full if the non-employee director remains in continuous service until immediately prior to such director’s: (i) death, (ii) “disability,” or (iii) the closing of a “change in control” transaction (as “disability” and “change in control” are defined in the Equity Incentive Plan).

Other Terms

To avoid adverse tax consequences to non-employee directors who reside outside of the United States, the board, in its sole discretion, may provide for non-statutory stock options of equal value in lieu of RSU grants, which will have a term of ten years from the date of grant and an exercise price per share equal to 100% of the fair market value of the underlying Class A common stock on the date of grant. All other terms and conditions that apply to RSU grants under the non-employee director compensation policy will apply to such options.

If permitted by the Company, a non-employee director may elect to defer cash retainers and/or RSU awards prior to being earned into deferred stock units of the Company, which shall settle upon the earlier to occur of the director’s “separation from service” as defined in the Treasury Regulations under Section 409Aprovisions of the Internal Revenue Code of 1986, as amended (the “Code”), Treasury regulations promulgated thereunder, administrative rulings and judicial decisions as of the date hereof, all of which are subject to change, possibly with retroactive effect. Changes in these authorities, and the interpretation thereof, may result in U.S. federal income tax consequences that differ from those discussed below. We have not sought, and will not seek, an opinion of counsel or a ruling from the Internal Revenue Service (the “IRS”) regarding the U.S. federal income tax consequences of the Reverse

The Audit Committee has appointed Armanino LLP (“Armanino”) as the independent registered public accounting firm to audit our consolidated financialinclude statements for the year ending December 31, 2023, including the audit of our internal control over financial reporting. Representatives of Armanino are expected to be present at the Annual Meeting and will be offered the opportunity to make a statement if they so desire. They will also be available to respond to appropriate questions.

The Audit Committee annually reviews Armanino’s independence and performance in deciding whether to retain Armanino or engage an alternative independent auditor. As part of this review, the Audit Committee, among other factors, considers the following:

Armanino’s historical and recent performance, including input from Audit Committee members, other independent directors and our management.

Armanino’s expertise and qualifications in serving as independent auditor for our different business operations.

A review of Armanino’s known legal risks and any significant legal or regulatory proceedings in which it is involved.

Other information on audit quality and performance including recent Public Company Accounting Oversight Board (the “PCAOB”) reports on Armanino and its peer firms.

Armanino’s tenure as our independent auditor, periodic rotation of the lead partner and engagement quality review partner, and the benefits of continuity of members of the engagement team. Continuity provides institutional knowledge and experience in performing the audit of the Company.

Armanino’s conclusion that they are independent with respect to serving as our independent auditor.

In addition to Armanino’s conclusion that they are independent, the Audit Committee believes that Armanino is independent and that there are controls and processes that help ensure such independence including the following: (a) Audit Committee oversight of Armanino includes at least four private meetings each year and an additional four private meetings with the Audit Committee Chair prior to each quarterly Audit Committee meeting; (b) Audit Committee interaction with, and review of, the industry and other qualifications of the lead partner and of the concurring partner including periodic rotation of such partners; (c) oversight of non-audit services that require preapproval by the Audit Committee precludes certain non-audit services and determines that Armanino is an appropriate service provider; (d) discussions with Armanino regarding their internal system of quality control including the firm’s internal quality reviews and procedures for maintaining independence with regard to audit clients; and (e) the overall regulatory framework and regulations and requirements of the PCAOB and the SEC that Armanino is subject to as an independent registered public accounting firm.

We are asking you to ratify the selection of Armanino as our independent registered public accounting firm for the 2023 fiscal year. Although ratification is not required by our bylaws or otherwise, the board is submitting the selection of Armanino to our stockholders for ratification because we value your views on our independent registered public accounting firm and as a matter of good corporate practice. In the event that our stockholders fail to ratify the selection, it will be considered as a direction to the Audit Committee to consider the selection of a different firm. Even if the selection is ratified, the Audit Committee in its discretion may select a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of us and our stockholders.
