TABLE OF CONTENTS

Will my shares be voted if I do not return my proxy?

If your shares are registered directly in your name, you are a “stockholder of record” who may vote at the Annual Meeting. As the stockholder of record, you have the right to direct the voting of your shares by voting over the internet, by telephone, by returning your proxy or by voting online during the Annual Meeting.

If your shares are held in an account at a bank or at a brokerage firm or other nominee holder, you are considered the beneficial owner of shares held in “street name,” and these proxy materials are being forwarded to you by your bank, broker or other nominee who is considered the stockholder of record for purposes of voting at the Annual Meeting. As the beneficial owner, you have the right to direct your bank, broker or other nominee on how to vote your shares and to participate in the Annual Meeting. You will receive instructions from your bank, broker or other nominee explaining how you can vote your shares and whether they permit internet or telephone voting. Follow the instructions from your bank, broker or other nominee included with these proxy materials, or contact your bank, broker or other nominee to request a voting instruction form. We encourage you to provide voting instructions to your bank, broker or other nominee by giving your voting instruction to them. This ensures that your shares will be voted at the Annual Meeting according to your instructions. If you want to vote in person virtually at the Annual Meeting, you must obtain a legal proxy from your broker, bank or other nominee and submit a copy to the Company’s Corporate Secretary in advance of the Annual Meeting. Further instructions will be provided to you as part of your registration process.

Note that under New York Stock Exchange, or NYSE, rules that apply to voting by nominees, which apply to both NYSE- and Nasdaq-listed companies, if you hold shares through a bank, broker or other institution and you do not provide your voting instructions to them at least 10 days before the Annual Meeting, that firm has the discretion to vote your shares on proposals that NYSE has determined are routine. Such firm will not have the discretion to vote your shares on proposals that NYSE has determined are non-routine. For purposes of the proposals in this proxy statement, the election of director nominees is a non-routine matter, 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 Annual Meeting held by a broker, as to which instructions have not been received from the beneficial owner or person entitled to vote such shares and with respect to which, on one 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 your proxy at any time before it is voted by notifying the Company’s Corporate Secretary in writing, by returning a signed proxy with a later date, by transmitting a subsequent vote over the internet or by telephone prior to the close of the internet voting facility or the telephone voting facility. You may also attend the virtual meeting and vote during the Annual 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 one-third of the total number of outstanding shares entitled to vote is necessary to constitute a quorum for the transaction of business at the Annual 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 Annual 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 Annual 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 the proposals described in this Proxy Statement. A broker non-vote occurs when a

3

TABLE OF CONTENTS

nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received instructions from the beneficial owner.

Proposal 1—Election of three Class I director nominees

The three 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 instructions with respect to your shares, your brokerage firm cannot vote your shares on Proposal 1. Shares held in street name 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” will have no effect on the voting on Proposal 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 in the vote tally for the election of the director.

Proposal 2—Ratification of the selection of Frank, Rimerman + Co. LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2025

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 Frank, Rimerman + Co. LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2025, 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.

Proposal 3—The Warrant Repricing Proposal

To approve Proposal 3, holders of a majority of the votes cast on the matter must vote FOR the proposal. For the approval of the Warrant Repricing Proposal, 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 3. The Warrant Repricing Proposal involves matters that we believe will be considered non-routine and brokers and other intermediaries will not have the discretion to vote in it without voting instructions. We encourage you to provide voting instructions to the organization that holds your shares by carefully following the instructions provided by such organization.

Proposal 4—The Inducement Warrant Proposal

To approve Proposal 4, holders of a majority of the votes cast on the matter must vote FOR the proposal. For the approval of the Inducement Warrant Proposal, 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 4. The Inducement Warrant Proposal involves matters that we believe will be considered non-routine and brokers and other intermediaries will not have the discretion to vote in it without voting instructions. We encourage you to provide voting instructions to the organization that holds your shares by carefully following the instructions provided by such organization.

Proposal 5—The Convertible Notes and Warrants Proposal

To approve Proposal 5, holders of a majority of the votes cast on the matter must vote FOR the proposal. For the approval of the Convertible Notes and Warrants Proposal, 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 5. The Convertible Notes and Warrants Proposal involves matters that we believe will be

considered non-routine and brokers and other intermediaries will not have the discretion to vote in it without voting instructions. We encourage you to provide voting instructions to the organization that holds your shares by carefully following the instructions provided by such organization.

Proposal 6—The Conversion Proposal

To approve Proposal 6, holders of a majority of the votes cast on the matter must vote FOR the proposal. For the approval of the Conversion Proposal, 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 6. The Conversion Proposal involves matters that we believe will be considered non-routine and brokers and other intermediaries will not have the discretion to vote in it without voting instructions. We encourage you to provide voting instructions to the organization that holds your shares by carefully following the instructions provided by such organization.

If there are insufficient votes to approve Proposals 1, 2, 3, 4, 5, or 6, 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 Annual 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. Should any other business come before the Annual Meeting, the persons named on the enclosed proxy will have discretionary authority to vote the shares represented by such proxies in accordance with their best judgment. If you hold shares through a broker, bank or other nominee as described above, they will not be able to vote your shares on any other business that comes before the Annual Meeting unless they receive instructions from you with respect to such matter.

What happens if the meeting is postponed or adjourned?

Your proxy may be voted at the postponed or adjourned Annual Meeting. You will still be able to change your proxy until it is voted.

How can I find out the results of the voting at the Annual Meeting?

Preliminary voting results will be announced at the Annual Meeting. Final voting results will be published in a Current Report on Form 8-K, or Form 8-K, that we expect to file with the SEC within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the Annual Meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results.

What does it mean if I receive more than one proxy card or voting instruction form?

It means that you have multiple accounts at the transfer agent or with brokers. Please complete and return all proxy cards or voting instruction forms to ensure that all of your shares are voted.

What if I have technical difficulties or trouble accessing the Annual Meeting?

If you encounter any technical difficulties with the virtual meeting platform on the Annual Meeting day, please call the technical support number that will be posted on the virtual Annual Meeting log-in page. Technical support will be available starting at 8:45 a.m. Pacific time on May 19, 2025 and will remain available until the Annual Meeting has ended.

What are the implications of being a “smaller reporting company”?

We are a “smaller reporting company,” meaning that the market value of our stock held by non-affiliates is less than $700 million and our annual revenue was less than $100 million during the most recently completed fiscal year. We may continue to be a smaller reporting company if either (i) the market value of our stock held by non-affiliates is less than $250 million or (ii) our annual revenue was less than $100 million during the most recently completed fiscal year and the market value of our stock held by non-affiliates is less than $700 million.

Specifically, as a smaller reporting company we may choose to present only the two most recent fiscal years of audited financial statements in our Annual Report and smaller reporting companies have reduced disclosure obligations regarding executive compensation.

Who should I contact if I have any additional questions?

If you hold your shares directly, please contract an investor relations representative at [email protected] . If your shares are held in street name, please contact the telephone number provided on your voting instruction form or contact your broker or nominee holder directly.

Anchor Board of Directors

The primary responsibilities of the Board of Directors are to provide oversight, strategic guidance, counseling and direction to the Company’s management. When considering whether directors and director nominees have the experience, qualifications, attributes and skills, taken as a whole, to enable the Board to satisfy its oversight responsibilities effectively in light of its business and structure, the Board will focus primarily on each person’s background and experience as reflected in the information discussed in each of the directors’ individual biographies set forth below in order to provide an appropriate mix of experience and skills relevant to the size and nature of its business. The Board is divided into three classes, with members of each class serving staggered three-year terms. The Board held 26 meetings in the 2024 fiscal year and all directors attended at least 75% of the Board meetings.

Anchor Corporate Governance

Anchor 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.

Anchor Director Independence

Each of the directors on the Board, 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 rules of the SEC and Nasdaq relating to the membership, qualifications and operations of the Audit Committee, as discussed below.

Anchor Stock Ownership Guidelines

The Board believes that it is in the best interests of the Company and its shareholders that directors and executive officers have a meaningful proprietary stake in the Company so that their interests are aligned 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.

Under our Stock Ownership Guidelines, non-employee 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 Members Five times the individual’s annual cash retainer (not including any chair, lead independent director, committee or committee chair service retainers)
Chief Executive Officer Five times the individual’s annual base salary
All Other Executive Officers Three times the individual’s annual base salary

Under our Stock Ownership Guidelines, each director and officer is required 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 later of the original period or three years from the effective date of such promotion or increase in base salary.

Anchor 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 transactions that hedge or offset any decrease in the market value of the Company’s securities.

Anchor 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.

Anchor Board Leadership Structure

The Board has determined that it should maintain the flexibility to select the Chair of the Board of the Company and adjust its Board leadership structure based on circumstances existing from time to time and based on criteria that are in the Company’s best interests and the best interests of our stockholders, including the composition, skills, diversity and experience of the Board and its members, specific challenges faced by the Company or the industry in which we operate and governance efficiency. The Board has adopted Corporate Governance Guidelines, which provides for the appointment of a lead independent director at any time when the Chairperson is not independent. As Mr. Rood, our Chief Executive Officer, is the Chairperson of the Board, the Board has appointed Linda J. Reiners as lead independent director.

Anchor Security Director

Under our National Security Agreement (the “NSA”), which terminated effective January 29, 2024, the Board includes a director who is approved by the CFIUS Monitoring Agencies. When the NSA was in effect, this director, referred to as the “Security Director,” had a fiduciary duty, to the extent consistent with his or her fiduciary duties to the Company and its stockholders under Delaware law, to the U.S. government. The Security Director served as the primary liaison between the Board of Directors and the CFIUS Monitoring Agencies and had authority to oversee compliance with the NSA. To the extent that the Security Director believed that a conflict of interest was reasonably likely to exist between her or his fiduciary duties under Delaware law to the Company and/or its stockholders and to the CFIUS Monitoring Agencies, the Security Director was required to promptly inform the CFIUS Monitoring Agencies of such conflict. The Security Director is the sole member of the Security Committee of the Board of Directors.

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

• 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;

• 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; and

• 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.

Our Second Amended and Restated Certificate of Incorporation, as amended, provides that the Security Director may only be removed for cause and with the approval of the CFIUS Monitoring Agencies and at least two-thirds of the voting power of the then outstanding shares of capital stock of the Company entitled to vote generally in the election of directors voting as a single class.

Anchor 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.

Anchor Committees of the Board of Directors

The Company has an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee, each of which has the composition and responsibilities described below.

• providing oversight of and recommending improvements to the Company’s overall compensation and incentive plans and benefit programs.

The Compensation Committee’s charter provides that it may delegate authority to one or more subcommittees or one or more officers of the Company. If the Compensation Committee delegates authority to an officer of the Company, such officer will not be delegated any authority that relates to the amount or form of compensation of “officers” as defined in Section 16 of the Exchange Act, which includes the authority related to the administration of compensation and incentive plans and benefit programs.

The charter also provides that the Compensation Committee may, in its sole discretion, retain or obtain the advice of a compensation consultant, legal counsel or other adviser to assist in the evaluation of CEO or executive officer compensation at the Company’s expense, and is directly responsible for the appointment, compensation and oversight of the work of any such adviser. However, before engaging or receiving advice from a compensation consultant, external legal counsel or any other adviser, the Compensation Committee will consider the independence of each such adviser, including the factors required by Nasdaq and the SEC.

During the fiscal year ended 2024, the Compensation Committee directly engaged Frederic W. Cook & Co., Inc. (“F.W.

Anchor Proposal 2 – Ratification of Appointment of Independent Registered Public Accounting Firm

The Audit Committee is responsible for the appointment, compensation (including final approval of audit and other fees), retention and oversight of the independent registered public accounting firm that audits our financial statements and our internal control over financial reporting. The Audit Committee has appointed Frank, Rimerman + Co. LLP (“Frank, Rimerman”) as the independent registered public accounting firm to audit our consolidated financial statements for the year ending December 31, 2025, including the audit of our internal control over financial reporting. Representatives of Frank, Rimerman 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 Frank, Rimerman’s independence and performance in deciding whether to retain Frank, Rimerman or engage an alternative independent auditor. As part of this review, the Audit Committee, among other factors, considers the following:

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

• Frank, Rimerman’s expertise and qualifications in serving as independent auditor for our different business operations.

• A review of Frank, Rimerman’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 Frank, Rimerman and its peer firms.

• Frank, Rimerman’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.

• Frank, Rimerman’s conclusion that they are independent with respect to serving as our independent auditor.

In addition to Frank, Rimerman’s conclusion that they are independent, the Audit Committee believes that Frank, Rimerman is independent and that there are controls and processes that help ensure such independence including the following: (a) Audit Committee oversight of Frank, Rimerman 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 Frank, Rimerman is an appropriate service provider; (d) discussions with Frank, Rimerman 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 Frank, Rimerman is subject to as an independent registered public accounting firm.

We are asking you to ratify the selection of Frank, Rimerman as our independent registered public accounting firm for the 2025 fiscal year. Although ratification is not required by our Amended and Restated Bylaws, as amended, or otherwise, the Board is submitting the selection of Frank, Rimerman 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.

Anchor Audit Committee Report

The Audit Committee annually reviews the performance of its duties under its charter. The charter complies with all current regulatory requirements, including requirements pertaining to the Nasdaq listing standards definitions, provisions and applicable exceptions concerning the independence of audit committee members.

In 2024, the Audit Committee held seven meetings. The Audit Committee’s meeting agendas are established by the Audit Committee Chair, Linda J. Reiners. The Audit Committee met with the senior members of the Company’s financial management team prior to each meeting.

As previously reported on the Company’s Current Report on Form 8-K, dated July 25, 2023, on July 19, 2023, the Company was informed by Armanino LLP (“Armanino”), the Company’s then independent registered public accounting firm, that Armanino would resign as the Company’s independent registered public accounting firm effective as of the filing of the Company’s quarterly report on Form 10-Q for the fiscal quarter ending September 30, 2023 (the “Q3 Form 10-Q”). Armanino advised the Company that its decision to resign was due to Armanino’s transition away from providing financial statement audit services to public companies. In light of Armanino’s determination, the Audit Committee initiated a process to select a new accounting firm to serve as the Company’s independent registered public accountant commencing with the audit of the Company’s financial statements for the fiscal year ended December 31, 2023. The Company filed the Q3 Form 10-Q on November 14, 2023, at which time Armanino’s resignation became effective.

On December 2, 2023, the Audit Committee appointed Frank, Rimerman to serve as the principal accountant to audit the Company’s financial statements.

Armanino audited the Company’s consolidated financial statements as of and for the fiscal years ended December 31, 2022 and 2021. The reports of Armanino on the financial statements of the Company for the fiscal years ended December 31, 2022 and 2021 did not contain any adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.

During the Company’s fiscal years ended December 31, 2022 and 2021, and through the interim period ended March 31, 2023, there were no disagreements between the Company and Armanino 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 Armanino, would have caused Armanino to make reference to the subject matter of the disagreements in connection with its audit reports on the Company’s financial statements. During the Company’s fiscal years ended December 31, 2022 and 2021, and the interim period ended March 31, 2023, Armanino did not advise the Company of any “reportable events” within the meaning of Item 304(a)(1)(v) of Regulation S-K with respect to the Company.

During the fiscal years ended December 31, 2021 and 2022, and the subsequent interim period through September 30, 2023, the Company has not consulted with Frank, Rimerman regarding either: (i) the application of accounting principles to any specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements; or (ii) any matter that was either the subject of a disagreement (as defined in Regulation S-K, Item 304(a)(1)(iv) and the related instructions) or reportable event (as defined in Regulation S-K, Item 304(a)(1)(v)).

The Audit Committee appointed Frank, Rimerman as the Company’s independent registered public accounting firm for the year ended December 31, 2024, and reviewed with the Company’s financial managers, the independent registered public accounting firm, and the Company’s internal auditor, overall audit scopes and plans, the results of internal and external controls and the quality of the Company’s financial reporting.

The Company’s management is primarily responsible for the preparation, presentation and integrity of the Company’s financial statements, accounting and financial reporting principles, internal controls, and procedures designed to ensure compliance with accounting standards, applicable laws and regulations. As the Company’s independent registered public accounting firm, Frank, Rimerman is responsible for performing an independent audit of the Company’s consolidated financial statements in accordance with generally accepted accounting principles and for expressing an opinion on the conformity of the audited financial statements to accounting principles generally accepted in the United States of America.

Anchor Proposal 3 – Warrant Repricing Proposal

Anchor General

Momentus is asking stockholders to approve, in accordance with Nasdaq Listing Rule 5635(d), the repricing of certain existing warrants of the Company (the “Warrant Repricing Proposal”). As previously disclosed, on February 11, 2025, we closed a transaction with an institutional investor as the purchaser (the “Investor”) in which we sold, and the Investor purchased, in a “best efforts” public offering (i) an aggregate of 300,000 shares of the Company’s Class A common stock, at a purchase price of $3.92499 per share of Class A common stock and one February 2025 Warrant (as defined below), (ii) in lieu of Class A common stock, at the election of the Investor, pre-funded warrants to purchase 973,886 shares of Class A common stock, at a purchase price of $3.925 per pre-funded warrant, and (iii) warrants to purchase 1,273,886 shares of Class A common stock (the “February 2025 Warrants”), pursuant to the terms of a Securities Purchase Agreement (the “Securities Purchase Agreement”) that we entered into with the Investor.

Additionally, the Securities Purchase Agreement provides for a warrant repricing transaction (the “Warrant Repricing Transaction”) with respect to warrants to purchase up to 2,228,572 shares of the Company’s Class A common stock initially issued by the Company to the Investor on each of September 17, 2024 (the “Class A September 2024 Warrant” and the “Class B September 2024 Warrant”), October 24, 2024 (the “October 2024 Warrant”), and December 18, 2024 (the ‘December 2024 Warrant”, and, collectively with the Class A September 2024 Warrant, the Class B September 2024 Warrant, and the October 2024 Warrant, the “Warrants”). The Securities Purchase Agreement requires the Company, among its other obligations, to hold a meeting of stockholders by May 11, 2025 to request stockholder approval of the Warrant Repricing Transaction (the “Stockholder Approval”) for a reduction of the exercise price per share of the Class A common stock under each Warrant to $3.80, subject to adjustment and an extension of the termination date of the Warrants to February 11, 2030.

If the Stockholder Approval is not obtained at the Annual Meeting, then the Company will be required to call another meeting of stockholders every sixty (60) days thereafter to seek the Stockholder Approval until the earlier of the date Stockholder Approval is achieved and August 10, 2025, which is the date that is six (6) months after the Warrant Repricing Transaction. If Stockholder Approval is not obtained by August 10, 2025, then automatically and without any approval of stockholders (i) the exercise price of the Warrants will be reduced (if and only if such new exercise price on the repricing date is lower than the exercise price of the Warrants then in effect) to be the Minimum Price (as defined below) of the Class A common stock on August 10, 2025, and (ii) the termination date of the Warrants shall automatically revert to the termination date as set forth in the originally issued Warrants.

The Warrants and the February 2025 Warrants all provide that the Investor will not have the right to exercise any portion of such warrants if the exercise would cause (i) the aggregate number of shares of our Class A common stock beneficially owned by the Investor (together with its affiliates) to exceed 4.99% (or, at the election of the Investor, 9.99%) of the number of shares of Class A common stock outstanding immediately after giving effect to the exercise, or (ii) the combined voting power of the Company’s securities beneficially owned by the Investor (together with its affiliates) to exceed 4.99% (or, at the election of the Investor, 9.99%) of the combined voting power of all of the Company’s securities then outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the warrants.

The Company previously solicited stockholder approval in connection with a similar warrant repricing transaction with respect to warrants to purchase up to 263,358 shares of the Company’s Class A common stock initially issued by the Company to the Investor on January 17, 2024 (the “January 2024 Warrants”). The Company called to order an annual meeting of stockholders on June 28, 2024 (the “2024 Annual Meeting”) to hold a vote on the repricing transaction of the January 2024 Warrants, and the proposal to reprice the January 2024 Warrants passed, resulting in (i) the exercise price of the January 2024 Warrants was reduced from $13.44 per share to $10.36 per share, and (ii) the termination date of the January 2024 Warrants was extended to March 7, 2029.

The Company also previously solicited stockholder approval in connection with a similar warrant repricing transaction with respect to warrants to purchase up to 414,896 shares of the Company’s Class A

common stock initially issued by the Company to the Investor on November 9, 2023 (the “November 2023 Warrants”). The Company called to order a special meeting of stockholders on March 15, 2024 (the “March Special Meeting”) to hold a vote on the repricing transaction of the November 2023 Warrants, however there were not present or represented by proxy a sufficient number of shares of the Company’s common stock in order to constitute a quorum at the March Special Meeting. Due to lack of quorum, the Company later cancelled the adjourned March Special Meeting and therefore, automatically and without any approval of stockholders, (i) the exercise price of the November 2023 Warrants was reduced to be the Minimum Price (as defined below) of the Class A common stock on May 9, 2024, and (ii) the termination date of the November 2023 Warrants was extended to May 9, 2029.

Anchor Proposal 4 – Inducement Warrant Proposal

Anchor General

Momentus is asking stockholders to approve, for purposes of complying with Nasdaq Listing Rule 5635(d), the potential issuance of up to 2,142,858 shares of Class A common stock upon the exercise of the Inducement Warrants issued by the Company pursuant to the Inducement Agreement (such shares of Class A common stock issuable upon exercise thereof, the “Inducement Warrant Shares”). The key terms of the Inducement Agreement and the Inducement Warrants relating to this Inducement Warrant Proposal are as summarized below and as described in the Current Report on Form 8-K filed by the Company with the SEC on March 21, 2025 (the “Form 8-K”).

The information set forth in this proposal is further qualified in its entirety by reference to the full text of the forms of the Inducement Warrant and Warrant Inducement Agreement, each attached as Exhibits 4.1 and 10.1, respectively to the Form 8-K. Stockholders are urged to carefully read these documents.

Anchor Description of the Inducement Agreement and Inducement Warrants

On March 20, 2025, we entered into the Inducement Agreement with an existing holder (the “Warrant Investor”) of certain existing warrants (the “Existing Warrants”) to purchase shares of Class A common stock that we previously issued pursuant to a Registration Statement on Form S-1 (File No. 333-282724), as amended, which was declared effective by the SEC on November 5, 2024 by the Company. Pursuant to the Inducement Agreement, the Warrant Investor agreed to, among other things, exercise for cash all of the Existing Warrants to purchase an aggregate of 1,071,429 shares of Class A common stock, at an exercise price of $1.93 per share. In consideration for exercising the Existing Warrants, we agreed to issue to the Warrant Investor the Inducement Warrants to purchase up to 2,142,858 shares of Class A common stock (the “Inducement Warrant Shares”).

Under the Inducement Warrants, we are obligated to seek stockholder approval for the exercise of the Inducement Warrants at either an annual or special meeting of stockholders to be held on or prior to May 19, 2025.

The Inducement Warrants, which were issued in conjunction with the entrance into the Inducement Agreement, will become exercisable upon the date we receive approval of our stockholders (the “Stockholder Approval Date”) in accordance with the applicable rules and regulations of Nasdaq, and may be exercised following such date through the five (5) year anniversary of the Stockholder Approval Date, at an exercise price of $2.00 per share of Class A common stock (the “Exercise Price”).

Upon obtaining stockholder approval, the Inducement Warrants will become immediately exercisable. The Exercise Price is subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting the Class A common stock. Subject to limited exceptions, the holder of the Inducement Warrants will not have the right to exercise any portion of its Inducement Warrants if the holder (together with such holder’s affiliates, and any persons acting as a group together with the holder or any of the holder’s affiliates) would beneficially own a number of shares of Class A common stock in excess of 4.99% of the shares of Class A common stock then outstanding. At the holder’s option, upon notice to the Company, the holder may increase or decrease this beneficial ownership limitation not to exceed 9.99% of the shares of Class A common stock then outstanding, with any such increase becoming effective upon 61 days’ prior notice to the Company.

In addition, the Company is obligated to file a registration statement on Form S-1 no later than thirty (30) calendar days following the date of the Inducement Agreement providing for the resale of the Inducement Warrant Shares and to use commercially reasonable efforts to cause such registration statement to become effective as soon as practicable. The Company also agreed, subject to certain exceptions, not to issue any shares of Class A common stock or common stock equivalents until thirty (30) days following the date of the Inducement Agreement or enter into or effect Variable Rate Transaction (as defined in the Inducement Agreement) until six (6) months following the date of the Inducement Agreement.

The Inducement Warrants, and the Inducement Warrant Shares underlying the Inducement Warrants, were issued pursuant to an exemption from the registration requirements of the Securities Act of 1933, as amended, contained in Section 4(a)(2) thereof.

TABLE OF CONTENTS

Anchor Why We Need Stockholder Approval

Our Board of Directors has determined that the Inducement Warrants, and the Company’s ability to issue Class A common stock upon exercise of the Inducement Warrants, are in the best interests of the Company and its stockholders because the exercise of the Existing Warrants in connection with the sale of the Inducement Warrants provided the Company with significant capital. Accordingly, we are seeking stockholder approval of this proposal in order to comply with the terms of the Inducement Agreement and Nasdaq Rule 5635(d), to the extent applicable.

Nasdaq Listing Rule 5635(d) requires stockholder approval in connection with a transaction, other than a public offering, involving the sale or issuance by the issuer of common stock (or securities convertible into or exchangeable for common stock) equal to 20% or more of the common stock or 20% or more of the voting power of such company outstanding before the issuance for a price that is less than the lower of: (i) the closing price of the common stock immediately preceding the signing of the binding agreement for the issuance of such securities and (ii) the average closing price of the common stock for the five (5) trading days immediately preceding the signing of the binding agreement for the issuance of such securities.

Accordingly, to satisfy Nasdaq Listing Rule 5635(d), we are seeking stockholder approval for the potential issuance of the 2,142,858 Inducement Warrant Shares. Further, under the Inducement Warrants, we are obligated to seek stockholder approval for the exercise of the Inducement Warrants at either an annual or special meeting of stockholders to be held on or prior to May 19, 2025.

Anchor Potential Effects of Approval of this Proposal

If approved, this proposal would allow the holder of the Inducement Warrants to acquire up to 2,142,858 Inducement Warrant Shares, subject to applicable beneficial ownership limitations. The number of Inducement Warrant Shares issuable under the Inducement Warrants is subject to adjustment in proportion to a stock split or reverse stock split. Once issued, each Inducement Warrant Share would have the same rights and privileges as each currently outstanding share of Class A common stock. The issuance of the Inducement Warrants or the Inducement Warrant Shares will not affect the rights of the holders of outstanding shares of Class A common stock, but any issuance of the Inducement Warrant Shares will have a dilutive effect on holders of our Class A common stock or securities convertible into Class A common stock, including the voting power, liquidation value, book value and economic rights of existing stockholders, and may result in a decline in the Company’s stock price or greater price volatility. In addition, upon issuance of the Inducement Warrant Shares, there would be a greater number of shares of our Class A common stock eligible for sale in the public markets. Any such sales, or the anticipation of the possibility of such sales, represents an overhang on the market and could depress the market price of our Class A common stock.

If this proposal is approved and the Inducement Warrants are exercised for cash, we will receive proceeds of up to an additional approximately $4.3 million, before giving effect to any beneficial ownership limitations contained in the Inducement Warrants, which may have the effect of limiting the Inducement Warrants holder’s ability to exercise the Inducement Warrants in full, or at all. Any proceeds that we may receive upon exercise(s) of the Inducement Warrants would allow us to continue to execute upon our current business plan.

Anchor Potential Effects of Non-Approval of this Proposal

We are not seeking the approval of our stockholders to authorize the Company’s entry into the transactions described above, as the Company has already done so and such documents are already binding obligations of the Company. The failure of stockholders to approve this proposal will not negate the existing terms of the transactions or the relevant documents, which will remain binding on the Company.

If the Company does not obtain stockholder approval at the Annual Meeting, the Company is required pursuant to the terms of the Inducement Warrants to hold a subsequent annual or special meeting every three (3) months thereafter to seek stockholder approval until the date stockholder approval is obtained. If the stockholders do not approve this proposal at the Annual Meeting, the Company will not be able to issue shares of Class A common stock to the Warrant Investor upon the receipt of a notice of exercise of the Inducement Warrants, thereby requiring the Company to hold another meeting seeking stockholder approval

at further expense to the Company. The Company’s ability to successfully implement its business plans and continue as a going concern is dependent on its ability to maximize capital raising opportunities, including exercises of its outstanding warrants, like the Inducement Warrants. Accordingly, if stockholder approval of this proposal is not obtained, the Company may need to seek alternative sources of financing, which financing may not be available on advantageous terms, or at all, and which may result in the incurrence of additional transaction expenses.

Anchor Vote Required

Assuming a quorum is present, the affirmative vote of a majority of the total votes cast on this proposal is required for approval of this Inducement Warrant Proposal. For purposes of the approval of this Inducement Warrant Proposal, abstentions and broker non-votes will have no effect on the result of the vote.

Anchor Proposal 5 – Convertible Notes and Warrants Proposal

Anchor General

Momentus is asking stockholders to approve, for purposes of complying with Nasdaq Listing Rule 5635(d), the potential issuance of shares of our Class A common stock to the holders of the Convertible Notes and Warrants in excess of 19.99% of our outstanding shares of Class A common stock pursuant to the Nasdaq Listing Rules.

Anchor Background

On July 12, 2024, the Company and Space Infrastructures Ventures, LLC (“SIV”), entered into a secured convertible promissory note (the “Initial Convertible Note”) pursuant to which the Company may borrow up to $2.3 million prior to September 1, 2024, consisting of (i) an initial loan in the principal amount of $500,000 which may be borrowed on or after July 17, 2024, and (ii) one or more subsequent loans totaling up to $1.8 million in aggregate principal amount which may be borrowed on or after August 7, 2024, with the $1.8 million subject to certain conditions including the availability of financing to SIV. Borrowings under the Initial Convertible Note bear interest at 15% per annum. Principal on the Initial Convertible Note is to be re-paid in four equal payments on a quarterly basis, commencing on December 1, 2024, and the Initial Convertible Note has a maturity date of September 1, 2025, at which time all accrued interest is due. As of September 30, 2024, all amounts available under the Initial Convertible Note have been borrowed by the Company.

Amounts borrowed under the Initial Convertible Note are secured by a lien on substantially all of the assets of the Company. In lieu of cash payments of accrued interest, SIV, in its sole discretion, may elect to receive shares of the Company’s Class A common stock at a conversion price of $7.41 per share (the “Conversion Price”). On the maturity date, subject to the satisfaction of applicable legal and regulatory conditions, all outstanding obligations under the Initial Convertible Note automatically convert into Class A common stock at the Conversion Price. The proceeds of the Initial Convertible Note are to be used solely for the following purposes: (a) to fund day-to-day working capital needs in the order course of business, consistent with Momentus practices prior to the execution of the Initial Convertible Note, (b) for general purposes in the ordinary course of business, consistent with Momentus practices prior to the execution of the Initial Convertible Note, and (c) to repay secured indebtedness owed to certain directors and officers of the Company.

On October 24, 2024, the Company and SIV entered into a secured convertible promissory note (the “Subsequent Convertible Note”, and, together with the Initial Convertible Note, the “Convertible Notes”) pursuant to which the Company may borrow up to $3.0 million in two tranches, consisting of (i) an initial loan in the principal amount of $2 million, and (ii) up to an additional $1 million in principal amount which may be borrowed from December 22, 2024 through February 14, 2025. Borrowings under the Subsequent Convertible Note bear interest at 15% per annum. The Subsequent Convertible Note has a maturity date of October 24, 2025, at which time all principal and accrued interest is due. Amounts borrowed under the Subsequent Convertible Note are secured by a lien on substantially all of the assets of the Company.

At any time after the date that is six (6) months after the original issuance date of the Subsequent Convertible Note, SIV may convert some or all of the outstanding obligations under the Subsequent Convertible Note into shares of Class A common stock at a conversion price of $7.41 per share. The conversion price and the number of shares of Class A common stock issuable upon conversion of the Subsequent Convertible Note is subject to appropriate adjustments in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting the Class A common stock.

In addition to the Subsequent Convertible Note, the Company agreed to issue to SIV warrants to purchase up to 463,223 shares of Class A common stock with an exercise price of $7.41 per share (the “SIV Warrants”), of which warrants to purchase 269,950 shares of Class A common stock were issued on November 14, 2024 following the funding of the first tranche under the Subsequent Convertible Note. The exercise price and the number of shares of Class A common stock issuable upon exercise of the SIV Warrants is subject to appropriate adjustments in the event of certain stock dividends and distributions,

TABLE OF CONTENTS

stock splits, stock combinations, reclassifications or similar events affecting the Class A common stock. SIV may not exercise the SIV Warrants prior to April 24, 2025, and the SIV Warrants will expire April 24, 2030.

Additionally, on November 30, 2024, the Company entered into amendments to the Convertible Notes. The amendments to the Subsequent Convertible Note accelerated the borrowing date for the second tranche of $1 million in principal amount to December 2, 2024, which borrowing date had previously been no earlier than December 22, 2024. Accordingly, the Company has now borrowed the full $3 million in principal amount under the Subsequent Convertible Note.

The amendments also permitted SIV to reserve out of the proceeds of the second tranche under the Subsequent Convertible Note of approximately $670 thousand, representing the amount of principal and interest due from the Company to SIV on December 1, 2024, under the Initial Convertible Note.

The amendments to the Convertible Notes also provide SIV the option to convert all amounts outstanding under either Convertible Note into shares of the Company’s Class A common stock at any time. Previously, the Initial Convertible Note only permitted conversion of interest when and as due, while the Subsequent Convertible Note only permitted conversion of outstanding amounts when and as due. The conversion price of amounts outstanding under the Initial Convertible Note and Subsequent Convertible Note remained unchanged from their respective original conversion prices described above.

In connection with the borrowing of the second tranche under the Subsequent Convertible Note, the Company issued to SIV warrants to purchase 193,273 shares of Class A common stock with an exercise price of $7.41 per share, as originally required by the Subsequent Convertible Note.

The Company also agreed to register the resale by SIV of all of the shares of Class A common stock issuable upon conversion of the Convertible Notes and the warrants issued to SIV. The Company registered the shares of Class A common stock issuable upon conversion of the Convertible Notes and the warrants issued to SIV pursuant to the Company’s registration statement on Form S-1, as amended (File No. 333-283727), filed with the Commission under the Securities Act that was declared effective on January 2, 2025.

Neither the Subsequent Convertible Note nor the SIV Warrants can be converted or exercised if it would cause the aggregate number of shares of Class A common stock beneficially owned by SIV (together with its affiliates) to exceed 4.99% of the number of shares of Class A common stock outstanding immediately after giving effect to the conversion or exercise, as applicable. By written notice to the Company, SIV may decrease or increase the ownership limitation to any other percentage, with agreement of the Company in the case of any decrease below 4.99% or increase above 9.99%, provided, that any such increase will not be effective until the 61st day after such notice is delivered to the Company.

The proceeds of the Subsequent Convertible Note are to be used solely to fund day-to-day working capital needs in the ordinary course of business, consistent with past practices, and for general purposes in the ordinary course of business, consistent with past practices. The Subsequent Convertible Note requires SIV’s consent to take certain actions, such as purchasing assets outside the ordinary course of business, extending financing, making capital expenditures in excess of $100,000, repaying debts outside the ordinary course of business or investing in any entity or enterprise.

On April 12, 2025, the Company entered into a master services agreement (the “Master Services Agreement” and the transactions contemplated thereby, the “Master Services Agreement Transactions”), between the Company and VLD. Pursuant to the Master Services Agreement, VLD shall provide services to design and produce components and systems that will be utilized by the Company or its customers in its spacecraft, systems, and components. In exchange for the services, the Company issued an aggregate of 477,455 shares of Company’s Class A common stock and 673,408 shares of the the Company’s Preferred Stock to VLD. The Preferred Stock is subject to the terms and conditions set forth in the Certificate of Designations, Rights and Limitations of Series A Convertible Preferred Stock filed by the Company with the Secretary of State of the State of Delaware (the “Certificate of Designations”).

Pursuant to the Certificate of Designations the Preferred Stock may not be converted into shares of Class A common stock if such conversion would result in the issuance, in the aggregate with all previous issuances of shares of Class A common stock, of greater than 19.9% of the amount of Class A common stock of the Company outstanding immediately preceding the date of the Master Services Agreement. Upon receipt of the requisite stockholder approval of the Conversion Proposal (as defined below), the foregoing restriction will automatically be lifted and the Preferred Stock will be convertible into an aggregate of 6,734,080 shares of common stock. The closing of the Master Services Agreement Transactions occurred simultaneously with the signing of the Master Services Agreement (the “VLD Closing”).

Anchor Nasdaq Stockholder Approval Requirement

The Class A common stock into which the Preferred Stock will convert, on a one-for-one basis, is listed on the Nasdaq Global Select Market, and, as such, the Company is subject to the Nasdaq Listing Rules, including Nasdaq Listing Rule 5635. In order to comply with the Nasdaq Listing Rules and to satisfy conditions under the Master Services Agreement, the Company is seeking stockholder approval of the Conversion Proposal. Nasdaq Listing Rule 5635(a)(1) requires stockholder approval prior to the issuance of securities that: (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 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. Although the issuance of the shares of non-voting Preferred Stock would not trigger the stockholder approval requirements of Nasdaq Listing Rule 5635 by itself, stockholder approval is required because the non-voting Preferred Stock may convert into voting Class A common stock in the future. Therefore, in accordance with the requirements of Nasdaq Listing Rule 5635(a), and pursuant to the terms of the Master Services Agreement and the Certificate of Designations, the Company is seeking the approval of its stockholders for the issuance of the non-voting Preferred Stock, which may be converted at VLD’s option on a one-for-one basis into shares of voting Class A common stock.

Anchor Consequences of Approving the Conversion Proposal

The Board is not seeking the approval of the Company’s stockholders to authorize the Company’s entry into the Master Services Agreement. The Master Services Agreement has already been executed and delivered, and the closing of the Master Services Agreement has occurred. If this Conversion Proposal is approved by stockholders, then:

  1. all of the shares of Preferred Stock issued in connection the Master Services Agreement Transactions will be eligible to be converted into 6,734,080 shares of Class A common stock at VLD’s option; and

  2. the rights and privileges associated with the new shares of Class A common stock issued upon the conversion will be identical to the rights and privileges associated with the Class A common stock held by existing stockholders.

Anchor Consequences of Failing to Approve the Conversion Proposal

If this Conversion Proposal is not approved, the Company would not be able to issue the shares of Class A common stock upon conversion to the holders of Preferred Stock. Additionally, unless stockholder approval of this Conversion Proposal is received:

  1. the Preferred Stock will remain outstanding in accordance with its terms;

  2. the Company may be required to submit this Conversion Proposal to stockholders again at a subsequent meeting of stockholders; and

  3. the Preferred Stock will retain a senior liquidation preference over shares of Class A common stock in connection with any liquidation of the Company and, accordingly, no payments will be made to holders of Class A common stock upon any liquidation of the Company unless the full liquidation preference of the Preferred Stock is paid.

Anchor Vote Required

Assuming a quorum is present, the affirmative vote of a majority of the total votes cast on this proposal is required for approval of this Conversion Proposal. For purposes of the approval of this Conversion Proposal, abstentions and broker non-votes will have no effect on the result of the vote.

Anchor Recommendation

The Board recommends that you vote FOR the Conversion Proposal.

Anchor Narrative to the Summary Compensation Table

The following is a discussion of certain terms of the employment agreements with our NEOs that we believe are necessary to understand the information disclosed in the Summary Compensation Table.

Anchor Base Salaries

The Company’s NEOs receive a base salary for services rendered to the Company. The base salary payable to each NEO is intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, role and responsibilities.

Anchor Bonuses

In fiscal year 2024, Mr. Rood, Mr. Ney, and Mr. Schwarz were eligible to earn annual cash bonuses targeted at 100%, 50%, and 40%, respectively, of their respective base salaries based on their performance, as determined by the Momentus Board of Directors.

Anchor Equity Compensation

Our Compensation Committee administers our 2021 Equity Incentive Plan (the “Equity Incentive Plan”) and approves the amount of, and terms applicable to, grants of stock options, RSUs, and other types of equity awards to employees, including the Named Executive Officers.

33

End Page 37

TABLE OF CONTENTS

The Equity Incentive Plan is intended to (i) attract and retain 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 success of our business.

The Equity Incentive Plan permits the grant of incentive stock options, nonstatutory stock options, stock appreciation rights (“SARs”), restricted stock, RSUs and stock bonus awards (all such types of awards, collectively, “equity awards”), although incentive stock options may only be granted to employees.

For the grant date fair values of the options and RSUs, please see the Summary Compensation Table above.

Anchor Perquisites

In 2024, Momentus provided its NEOs with benefits intended to be competitive with market practices and to motivate them to carry out their duties with respect to the Company. Some of these benefits are provided under the NEOs’ applicable employment agreements, as described below. The amount of these benefits has been included in the Summary Compensation Table in the “All Other Compensation” column.

Momentus pays the entire premiums associated with its NEOs’ medical insurance coverage; because the Company does not pay the entire premium with respect to the medical insurance coverage of employees generally, the amounts associated with the additional percentage paid by the Company have been included in the Summary Compensation Table in the “All Other Compensation” column.

The Company has established a 401(k) plan which covers all employees. Participants may make voluntary contributions to the plan subject to Internal Revenue Service limitations. The Company does not provide a matching contribution. Momentus also provides other benefits to its NEOs on the same basis as provided to all of its employees, including vacation and paid holidays.

Mr. Rood is also entitled to reimbursement for his commuting (including first class airfare) and temporary housing expenses from his residence to Momentus’ headquarters, as reasonably required and a gross-up payment of any income taxes withheld on such commuting and temporary housing expenses until the fourth anniversary of his start date.

Anchor DIRECTOR COMPENSATION

Anchor Director Compensation Policy

The Company adopted a non-employee director compensation policy to govern the Board. 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 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:

• 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

• An additional [ ] RSUs 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).

Anchor 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).

Anchor 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 409A of the Internal Revenue Code of 1986, as amended, or the date determined by the Company.

The Company will reimburse each non-employee director for ordinary, necessary and reasonable out-of-pocket travel expenses to cover in-person attendance at, and participation in, Board and committee meetings, provided they are reimbursed in accordance with the Company’s travel and expense policy.

Anchor Security Director and Chairperson of Security Committee

In addition to compensation under the non-employee director compensation policy, Victorino G. Mercado, as the Security Director and the Chair of the Security Committee, will receive additional compensation pursuant to the terms of his offer letter.

Anchor SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

Anchor Security Ownership of Certain Beneficial Owners

The following table sets forth certain information known to us regarding the beneficial ownership of our Class A common stock as of April 3, 2025 for each of our NEOs, executive officers, directors, all executive officers and directors as a group and each person known by us to be the beneficial owner of more than 5% of our Class A common stock. 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. Under those rules, beneficial ownership includes securities that the individual or entity has the right to acquire, such as through the exercise of warrants or stock options or the vesting of RSUs, within 60 days of April 3, 2025. Class A common stock subject to warrants or options that are currently exercisable or exercisable within 60 days of April 3, 2025 or subject to RSUs that vest within 60 days of April 3, 2025 are considered outstanding and beneficially owned by the person holding such warrants, options or RSUs for the purpose of computing the percentage ownership of that person but are not treated as outstanding for the purpose of computing the percentage ownership of any other person. Except as noted by footnote, and subject to community property laws where applicable, based on the information provided to us, we believe that the persons and entities named in the table below have sole voting and investment power with respect to all shares shown as beneficially owned by them. Unless otherwise noted, the business address of each of our directors and executive officers is c/o Momentus Inc., 3901 N. First Street, San Jose, California 95134. The percentage of beneficial ownership of our shares of Class A common stock is calculated based on 4,779,337 shares of Class A common stock outstanding as of April 3, 2025.
