PROSPECTUS SUMMARY

The following summary highlights selected information contained elsewhere in this prospectus and does not contain all of the information that you should consider in making your investment decision. Before investing in our securities, you should carefully read this entire prospectus, including our consolidated financial statements and the related notes and other documents incorporated by reference herein this prospectus and the information set forth under the headings “Risk Factors.”

The Company

Momentus is a U.S. commercial space company that offers satellites, satellite buses, and other satellite components, transportation and infrastructure services, including hosted payloads and other in-orbit services to help enable the commercialization of space. Satellite operators are our principal customers and target customers. Momentus offers satellites and satellite buses and technology designed to meet the specific needs of government and commercials customers. The Company also performs analysis and provides engineering services to U.S. Government organizations.

Products that we provide or plan to provide include satellites, satellite buses, solar arrays, and other satellite components. Our satellites and satellite technologies offer competitive advantages to customers such as greater payload capability, significant on-orbit power, flexibility of design and ability to accommodate a range of sensors, communications equipment, and other space instruments, low cost, and speed of delivery.

Our Tape Spring Solar Array (“TASSA”) is an innovative solar array that Momentus is developing. It offers the potential to produce power at substantially lower cost than competing arrays. It also has important advantages from its ability to be deployed and retracted to protect the array from in-space collisions with debris and to more easily maneuver the satellite to different locations or adjust its characteristics.

Services that we provide or plan to provide include “last mile” satellite transportation, payload-hosting, on-orbit satellite refueling, on-orbit inspection, on-orbit satellite maintenance, de-orbiting, debris removal, and other satellite-to-satellite service offerings. We believe our planned service offerings will increase deployment options for satellite operators and lower their operating costs relative to traditional approaches while also minimizing environmental impact given our choice of water as a propellant.

We plan to provide these services with Orbital Service Vehicles (“OSVs”) that we design and manufacture. While we plan to eventually operate a family of progressively larger and more capable OSVs, we are currently focused on the first vehicle of the family, Vigoride, which will primarily operate in low-earth orbit (LEO). We believe that Vigoride, has the ability to deliver fast, versatile, and cost-effective transportation and infrastructure services to our customers. We conducted our inaugural test and demonstration mission with Vigoride in 2022 as well as two additional test and demonstration missions during 2023. The Company plans to use technological milestones like completion of development of Block 2.2 configuration of the Vigoride OSV, MET propulsion, and TASSA in space, and experience gained in both satellite deployment and hosted payloads as standards to build new OSVs and explore commercial opportunities.

Our transportation service offering focuses on delivering our customers’ satellites to precision orbits of their choosing. To accomplish this, we partner with leading launch service providers, such as SpaceX to “ride share” our customer’s satellites from Earth to space on a midsized or large rocket. Customer satellites can also be carried aboard small launch vehicles for dedicated missions. Our OSVs would then provide “last mile” transportation services from the rocket’s drop-off orbit to a custom orbit of the satellite operator’s choosing. We believe this “hub-and-spoke” model has the potential to expand our customers’ deployment options relative to what they would be able to achieve with ride share launch alone, while reducing their costs relative to what they could achieve with a dedicated small launch vehicle. Over time, we plan to begin introducing additional services beyond transportation.

Our OSVs will initially be expendable, meaning they will be used to perform services before they de-orbit themselves upon completion of their first mission. However, our goal is to eventually make our OSVs reusable, or capable of remaining in space to conduct follow-on missions, which has the potential to lower our cost to deliver services to our customers. To achieve reusability, we need to develop additional technologies that will allow our vehicles to locate and navigate to customer satellites in space, physically connect to them, and perform a variety of robotic operations including fluid transfer.

TABLE OF CONTENTS

We are also offering variants of our Vigoride OSV to government and commercial customers as a traditional bus manufacture and satellite prime contractor. Vigoride, and its variants, M-500 and M-1000, are being offered to provide payload technology demonstrations as well as forming the space infrastructure backbone for constellations of satellites.

Momentus offers or plans to offer production and operation of small satellites to meet a range of defense, government, and commercial needs such as communications, tracking of missiles, remote sensing, and space domain awareness. There is a growing need for such capabilities for defense, government, and commercial customers. Technologies used to support the Hosted Payload market are directly applicable to offering customer-owned satellites for use in constellations. Momentus is offering high-volume production of busses, based on Vigoride’s technologies, and integrating customer’s unique payloads for a variety of missions ranging from communications to Earth Observation. This market heavily leverages prior investments in satellite technology to access a large and growing market segment. We introduced variants of Vigoride tailored specifically for constellation applications as M-500 and M-1000 in August 2023.

For a further description of the risks associated with our business, see “Risk Factors.” Investors are cautioned to review the following description of Momentus’ business together with the entirety of this prospectus, including the within-mentioned risk factors.

Nasdaq Deficiency

Our Common Stock is currently listed for quotation on the Nasdaq Capital Market. We are required to meet Nasdaq listing rules in order to maintain such listing.

On March 27, 2024, the Company received a letter from the Listing Qualifications Staff of Nasdaq (the “Staff”) indicating that, based upon the closing bid price of the Common Stock, the Company was not in compliance with the requirement to maintain a minimum bid price of $1.00 per share (the “Minimum Bid Price Requirement”) for continued listing on The Nasdaq Capital Market, as set forth in Nasdaq Listing Rule 5550(a)(2) (the “Original Notice”). At that time, the Company was provided a compliance period of 180 calendar days from the date of the Original Notice, or until September 23, 2024, to regain compliance with the Minimum Bid Price Requirement, pursuant to Nasdaq Listing Rule 5810(c)(3)(A).

As the Company did not regain compliance with the Minimum Bid Price Requirement by September 23, 2024, and it was determined that the Company is not eligible for another 180 calendar-day extension because it did not meet the minimum stockholders’ equity initial listing requirements of $5,000,000 for Nasdaq, as set forth under Nasdaq Listing Rule 5505(b), the Company received a delisting determination letter on September 24, 2024 (the “Delisting Determination Letter”).

The Company also received deficiency letters on May 23, 2024 and August 21, 2024, respectively, from the Staff notifying the Company that the Company had not filed its Form 10-Q for the periods ending March 31, 2024 and June 30, 2024, respectively, as required for continued listing on the Nasdaq under Nasdaq Listing Rule 5250(c)(1) (the “Periodic Reporting Requirement”). Pursuant to Nasdaq Listing Rule 5810(d)(2), the failures to comply with the Periodic Reporting Requirement individually became additional and separate bases for delisting.

On October 15, 2024, the Company filed its Quarterly Reports on Form 10-Q for the quarters ended March 31, 2024 and June 30, 2024, resolving two of the deficiencies previously identified by Nasdaq.

On October 17, 2024, the Company received further notice from the Listing Qualifications Department of Nasdaq notifying the Company that it was not in compliance with the requirements of Nasdaq Listing Rule 5550(b) as a result of not having a minimum of $2,500,000 in stockholders’ equity for continued listing as of June 30, 2024, a market value of listed securities of at least $35 million, or net income from continuing operations of $500,000 in the most recently completed fiscal year or in two of the last three most recently completed fiscal years.

As permitted by Nasdaq rules, the Company timely requested a hearing before a Nasdaq Hearing Panel (the “Panel”) to appeal Nasdaq’s delisting determination. The Company requested and received a stay of the suspension of trading and delisting of the Common Stock pending the conclusion of the hearing process, which allows the Common Stock to remain listed on Nasdaq at least until the Panel renders a decision following the hearing. The hearing before the Panel was held on November 14, 2024, at which the Company requested a suspension of delisting pending its return to compliance. The Company called a special meeting of stockholders on December 2, 2024, where the stockholders approved a reverse stock split as part of the Company’s plan to regain compliance with Nasdaq rules.

TABLE OF CONTENTS

2024 Reverse Stock Split

In order to regain compliance with the Minimum Bid Price Requirement, on December 4, 2024 the board of directors of the Company approved a reverse stock split ratio of 1-for-14 approved by the stockholders of the Company on December 2, 2024 (the “Reverse Stock Split”). The Reverse Stock Split will be effective as of 5:00 p.m. eastern time on Thursday, December 12, 2024 (the “Effective Date”), with the Common Stock trading on the Nasdaq Capital Market on a reverse-split adjusted basis under the Company’s trading symbol “MNTS”, at the market open on Friday, December 13, 2024.

Going Concern Uncertainty

Our consolidated interim financial statements are prepared assuming that the Company will continue as a going concern. The going concern basis of presentation assumes that the Company will continue in operation one year after the date the consolidated interim financial statements are issued and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. The Company’s ability to continue as a going concern is dependent on the Company’s ability to successfully raise capital to fund its business operations and execute on its business plan. To date the Company remains heavily focused on growth and continued development of its proprietary technology, and as a result, it has not generated sufficient revenues to provide cash flows that enable the Company to finance its operations internally and the Company’s financial position and operating results raise substantial doubt about the Company’s ability to continue as a going concern. This is reflected by the Company’s incurred net loss of $23.1 million for the nine months ended September 30, 2024, and accumulated deficit of $396.1 million as of September 30, 2024. Additionally, the Company used net cash of $10.9 million to fund its operating activities for the nine months ended September 30, 2024, and had cash and cash equivalents of $0.8 million as of September 30, 2024.

Pursuant to the requirements of ASC Sub-Topic 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date the consolidated interim financial statements are issued. This evaluation does not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented or are not within control of the Company as of the date the consolidated interim financial statements are issued. When substantial doubt exists, management evaluates whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company’s ability to continue as a going concern. The mitigating effect of management’s plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the consolidated interim financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the consolidated interim financial statements are issued.

In connection with the preparation of the consolidated interim financial statements for the nine months ended September 30, 2024, management conducted an evaluation and concluded that there were conditions and events, considered in the aggregate, which raised substantial doubt as to the Company’s ability to continue as a going concern within twelve months after the date of the issuance of such consolidated interim financial statements. The Company believes that its current level of cash and cash equivalents are not sufficient to fund its regular operations, scaling of commercial production, and maintain its existing services and products. These conditions raise substantial doubt regarding its ability to continue as a going concern for a period of at least one year from the date of issuance of these consolidated interim financial statements. In order to proceed with the Company’s business plan and operating strategy, the Company will need to raise substantial additional capital to fund its operations. Until such time, if ever, the Company can generate revenues sufficient to achieve profitability, the Company expects to finance its operations through equity or debt financings, which may not be available to the Company on the timing needed or on terms that the Company deems to be favorable. In an effort to alleviate these conditions, the Company continues to seek and evaluate all opportunities to access additional capital through any available means.

As a result of these uncertainties, and notwithstanding management’s plans and efforts to date, there is substantial doubt about the Company’s ability to continue as a going concern. If the Company is unable to raise substantial additional capital in the near term, the Company’s operations and business plan will need to be scaled back or halted altogether. Additionally, if the Company is able to raise additional capital but that capital is insufficient to provide a bridge to full commercial production at a profit, the Company’s operations could be severely curtailed or cease entirely and the Company may not realize any significant value from its assets.

Litigation Update

On September 16, 2024, the U.S. District Court for the Northern District of California issued an order primarily approving the settlement and providing for notice of the settlement to stockholders of the Company in the matters captioned Hanna v. Kabot, et al., Case No. 5:23-cv-00374 (N.D. Cal.); Rivlin v. Kabot, et al., Case No. 2:23-cv-03120 (C.D. Cal.); Lindsey v. Quiroga, et al., Case No. 20230674 (Del. Ch.); and the litigation demand made by Momentus stockholder, Kamal Qureshi (collectively, the “Derivative Matters”). The proposed settlement calls for the Company to adopt certain corporate governance reforms and pay lead plaintiffs’ attorney’s fees, litigation expenses, and lead plaintiff service awards. Plaintiffs have moved for final approval of the proposed settlement to resolve all three actions. The settlement approval motion was set to be heard on November 21, 2024. On November 14, 2024, with no parties or the court having received any objection to the proposed settlement, the court took the settlement approval motion under consideration without oral argument.

On March 24, 2023, Lev Khasis filed a verified complaint against the Company in the Delaware Court of Chancery (Case. No. 2023-0361) seeking indemnification and advancement of expenses from the Company. On April 17, 2023, the Company filed a motion to dismiss. On May 16, 2023. Mr. Khasis filed an amended complaint. On May 23, 2023, Momentus filed a motion to dismiss the amended complaint. Separately, Khasis has requested an expedited trial in his claim for advancement of fees. On June 23, 2023, the Court of Chancery ordered that Khasis indemnification litigation will not be stayed pending the appeal of the Kokorich claim. Moreover, the Court of Chancery further ordered the parties to prepare a scheduling order to the Court which includes all relevant deadlines to argue the Company’s motion to dismiss and Khasis’ expedited motion for advancement concurrently. On October 17, 2023, the parties reached an agreement to stay the proceeding until January 1, 2024. On October 18, 2023, the Company conditionally paid Mr. Khasis $0.1 million related to Mr. Khasis’ legal expenses. In response to the Court’s request for a status update, the Plaintiff moved to voluntarily dismiss its complaint without prejudice, which Momentus did not oppose. On November 26, 2024, the Court granted Plaintiff’s motion.

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 Momentus 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 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 Common Stock at a conversion price of $0.5292 per share. The conversion price and the number of shares of 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 Common Stock.

In addition to the Subsequent Convertible Note, the Company agreed to issue to SIV warrants to purchase up to 6,485,103 shares of Common Stock, or 463,222 shares of Common Stock on a Post-Split Basis, with an exercise price of $0.5292 per share (the “SIV Warrants”), of which warrants to purchase 3,779,289 shares of 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 Common Stock issuable upon exercise of the SIV Warrants is subject to appropriate adjustments in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting the 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 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 2,705,814 shares of Common Stock with an exercise price of $0.5292 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 Common Stock issuable upon conversion of the Convertible Notes and the warrants issued to SIV.

TABLE OF CONTENTS

9.99% of the number of shares of Common Stock outstanding immediately after giving effect to the conversion or exercise, as applicable. By written notice, SIV may, with the agreement of the Company, from time to time increase or decrease this ownership limitation to any other percentage.

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.

Implications of Being an Emerging Growth Company

As a company with less than $1.235 billion in revenues during our last completed fiscal year, we qualify as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. An emerging growth company may take advantage of specified reduced reporting requirements that are otherwise applicable generally to public companies. These reduced reporting requirements include, but are not limited to:

•	an exemption from compliance with the auditor attestation requirement on the effectiveness of our internal control over financial reporting;

•	an exemption from compliance with any requirement that the Public Company Accounting Oversight Board may adopt regarding a supplement to the auditor’s report providing additional information about the audit and the financial statements;

•	reduced disclosure about our executive compensation arrangements; and

•	an exemption from the requirements to obtain a non-binding advisory vote on executive compensation or a stockholder approval of any golden parachute arrangements.

We may choose to take advantage of some, but not all, of the available benefits under the JOBS Act. Accordingly, the information contained herein may be different from the information you receive from other public companies in which you hold stock. Further, pursuant to Section 107 of the JOBS Act, as an emerging growth company, we have elected to use the extended transition period for complying with new or revised accounting standards until those standards would otherwise apply to private companies. As a result, our consolidated financial statements may not be comparable to the financial statements of issuers who are required to comply with the effective dates for new or revised accounting standards that are applicable to public companies, which may make the Common Stock less attractive to investors.

We will remain an emerging growth company until the earlier of (1) the last day of the fiscal year (a) following November 13, 2024, (b) in which we have total annual gross revenue of at least $1.235 billion, or (c) in which we are deemed to be a large accelerated filer, which means the market value of the Common Stock that is held by non-affiliates exceeds $700 million as of the last business day of our most recently completed second fiscal quarter, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.

RISK FACTORS

Investing in our Common Stock involves a high degree of risk. Prior to making a decision about investing in our Common Stock, you should consider carefully the specific risk factors discussed above under “Cautionary Note Regarding Forward-Looking Statements”, under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on June 6, 2024, which is incorporated by reference into this prospectus in its entirety, as well as any amendment or updates to our risk factors reflected in subsequent filings with the SEC, including Form 10-K/A filed on September 16, 2024 and any prospectus supplement hereto or any related free writing prospectus. These risks and uncertainties are not the only risks and uncertainties we face. Additional risks and uncertainties not presently known to us, or that we currently view as immaterial, may also impair our business. If any of the risks or uncertainties described in our SEC filings or any additional risks and uncertainties actually occur, our business, financial conditions, results of operations, stock price and prospectus could be materially and adversely affected.

TABLE OF CONTENTS

SELLING STOCKHOLDER

This prospectus covers the resale or other disposition by the Selling Stockholder identified in the table below of the Conversion Shares and the Warrant Shares, consisting of up to an aggregate of 15,414,414 shares of Common Stock. The Selling Stockholder acquired the Conversion Shares and Warrants into which the Conversion Shares and Warrant Shares can be converted or exercised respectively, in the transaction described above under the heading “Prospectus Summary—Convertible Notes Transactions.”

The Convertible Notes and the Warrants to be issued in the Convertible Notes Transactions provide that the Selling Stockholder will not have the right to convert the Convertible Notes or exercise any portion of the Warrants if such conversion or exercise would cause (i) the aggregate number of shares of Common Stock beneficially owned by the Selling Stockholder (together with its affiliates) to exceed 4.99% (the “Ownership Limitation”) of the number of shares of Common Stock outstanding immediately after giving effect to the conversion or exercise, or (ii) the combined voting power of the Company’s securities beneficially owned by the Selling Stockholder (together with its affiliates) to exceed the Ownership Limitation 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. By written notice to the Company, the Selling Stockholder may decrease or increase the Ownership Limitation to any other percentage, with agreement of the Company in 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 by the Selling Stockholder.

The table below sets forth, as of December 9, 2024, the following information regarding the Selling Stockholder:

•	Name of the Selling Stockholder;

•	Number of shares of Common Stock beneficially owned by the Selling Stockholder prior to the Convertible Notes Transactions; and

•	Number of warrants issuable upon the conversion of the Convertible Notes and the exercise of the Warrants;

The number of shares owned are those beneficially owned, as determined under the rules of the SEC, and the information is not necessarily indicative of beneficial ownership for any other purpose.

All information with respect to the Common Stock ownership of the Selling Stockholder has been furnished by or on behalf of the Selling Stockholder. We believe, based on information supplied by the Selling Stockholder, that except as may otherwise be indicated in the footnotes to the table below, the Selling Stockholder have sole voting and dispositive power with respect to the shares of Common Stock reported as beneficially owned by the Selling Stockholder. Because the Selling Stockholder identified in the table may sell some or all of the shares of Common Stock beneficially owned by them and covered by this prospectus, and because there are currently no agreement, arrangements, or understanding with respect to the sale of any of the shares of Common Stock, no estimate can be given as to the number of shares of Common Stock available for resale hereby that will be held by the Selling Stockholder upon termination of this offering. In addition, the Selling Stockholder may have sold, transferred or otherwise disposed of, or may sell, transfer or otherwise dispose of, at any time from time to time, the shares of Common Stock they beneficially own in transactions exempt from the registration requirements of the Securities Act after the date on which it provided the information set forth in the table below. We have, therefore, assumed for the purposes of the following table, that the Selling Stockholder will sell all of its shares of Common Stock owned beneficially by them that are covered by this prospectus, but will not sell any other shares of Common Stock that they presently own. Except as set forth below, the Selling Stockholder have not held any position or office, or has otherwise had a material relationship, with us or any of our subsidiaries within the past three ears other than as a result of the ownership of our shares of Common Stock or other securities.

The Selling Stockholder and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. The Selling Stockholder have informed the Company that they do not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

Miscellaneous			$5,000

Item 14.

Indemnification of Directors and Officers.

Section 145 of the Delaware General Corporation Law (the “DGCL”) provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with any threatened, pending or completed actions, suits or proceedings in which such person is made a party by reason of such person being or having been a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise. The DGCL provides that Section 145 is not exclusive of other rights to which those seeking indemnification may be entitled under any bylaws, agreement, vote of stockholders or disinterested directors or otherwise. The registrant’s Second Amended and Restated Certificate of Incorporation, as amended, and Amended and Restated Bylaws, as amended, provide for indemnification by the registrant of its directors and officers to the fullest extent permitted by the DGCL.

Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (1) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) for unlawful payments of dividends or unlawful stock repurchases, redemptions or other distributions or (4) for any transaction from which the director derived an improper personal benefit. The registrant’s Second Amended and Restated Certificate of Incorporation, as amended, provides for such limitation of liability to the fullest extent permitted by the DGCL.

The registrant has entered into, and expects to continue to enter into, indemnification agreements with each of its directors and executive officers. These agreements provide that the registrant will indemnify each of its directors and such officers to the fullest extent permitted by law.

Any underwriting agreement or distribution agreement that the registrant enters into with any underwriters or agents involved in the offering or sale of any securities registered hereby may require such underwriters or dealers to indemnify the registrant, some or all of its directors and officers and its controlling persons, if any, for specified liabilities, which may include liabilities under the Securities Act.

The registrant also maintains standard policies of insurance under which coverage is provided to its directors and officers against loss arising from claims made by reason of breach of duty or other wrongful act, while acting in their capacity as directors and officers of the registrant.

Recent Sales of Unregistered Securities.

Issuance of Common Stock to Non-employees: During the year ended December 31, 2023, the Company issued 2,700 shares of Common Stock to a third-party consulting firm in exchange for public relations services. The shares were not issued under any equity incentive plan of the Company. Under the agreement, the shares were contingently forfeitable in the event of early termination by the Company. The shares had an issuance date fair value of

TABLE OF CONTENTS

$0.1 million to be recorded as consulting expense over the six-month term of the agreement. Related consulting expense of $0.1 million was recognized over the six-month term of the agreement. The Company issued no shares to non-employees during the nine months and year ended September 30, 2024.

Private Placement:

On September 15, 2024, the Company engaged in a private placement pursuant to which the Company agreed with an investor (the “Investor”) to (i) sell and issue to such stockholder the pre-funded warrants (the “Pre-Funded Warrants”) to purchase Common Stock, Class A Warrants to purchase Common Stock and Class B Warrants to purchase Common Stock.

The purchase price of each Pre-Funded Warrant equals the price per share at which shares of our Common Stock are being sold in the private placement minus $0.00001, and the exercise price of each Pre-Funded Warrant equals $0.00001 per share. The Pre-Funded Warrants are exercisable at any time after their original issuance and will not expire until exercised in full. The Class A Warrants have an exercise price per share of Common Stock equal to $0.575 per share. Class A Warrants will expire March 17, 2030, and the Class B Warrants will expire March 17, 2026. The exercise price and the number of shares of Common Stock issuable upon exercise of the Class A Warrants and the Class B Warrants is subject to appropriate adjustments in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting the Common Stock. The Investor may not exercise the Class A Warrants and the Class B Warrants until the date that is 6 months after the original issuance date.

In connection with the private placement, on September 15, 2024, the Company entered into a Placement Agency Agreement with the Placement Agent. As part of its compensation for acting as Placement Agent for the private placement, the Company paid the Placement Agent a cash fee of 7.0% of the aggregate gross proceeds and also agreed to issue to the Placement Agent Warrants at an exercise price of $0.6325, which are exercisable immediately. One half of the Placement Agent Warrants have a term of eighteen months from September 15, 2024, and the other half of the Placement Agent Warrants have a term of five years from September 15, 2024.

Convertible Notes Transactions

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 Momentus 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 Momentus Common Stock at a conversion price of $0.52908 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 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 Momentus.

TABLE OF CONTENTS

In addition to the Subsequent Convertible Note, the Company agreed to issue to SIV warrants to purchase up to 6,485,103 shares of Common Stock, or 463,222 shares of Common Stock on a Post-Split Basis with an exercise price of $0.5292 per share (the “SIV Warrants”), of which warrants to purchase 3,779,289 shares of 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 Common Stock issuable upon exercise of the SIV Warrants is subject to appropriate adjustments in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting the Common Stock. SIV may not exercise the SIV Warrants prior to April 24, 2025, and the SIV Warrants will expire April 24, 2030.

The Company also agreed to register the resale by SIV of all of the shares of Common Stock issuable upon conversion of the Convertible Notes and the warrants issued to SIV.

Neither the Subsequent Convertible Note nor the SIV Warrants can be converted or exercised if it would cause the aggregate number of shares of Common Stock beneficially owned by SIV (together with its affiliates) to exceed 9.99% of the number of shares of Common Stock outstanding immediately after giving effect to the conversion or exercise, as applicable. By written notice, SIV may, with the agreement of the Company, from time to time increase or decrease this ownership limitation to any other percentage.

Undertakings.

The undersigned registrant hereby undertakes to

(a)	Provide to the underwriters at the closing specified in the underwriting agreement certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

(b)	To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)	To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii)

To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii)

To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement, provided, however, that paragraphs (b)(1)(i), (ii), and (iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 (15 U.S.C. 78m or 78o(d)) that are incorporated by reference in the registration statement.

(c)

That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(d)	To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(e)

For the purpose of determining liability under the Securities Act of 1933 to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A (§230.430A of this chapter), shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration

statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(f)

That for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)	Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)	Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii)

The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv)	Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(g)

The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(h)

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

(i)

That:

(1)

For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(2)

For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
