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, the registration statement of which this prospectus is a part and the documents incorporated by reference herein, including the information set forth under the heading “Risk Factors” and our consolidated financial statements and the related notes herein.

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 commercial customers.

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 with Vigoride 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

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, we received a letter from the Listing Qualifications Staff of Nasdaq (the “Staff”) indicating that, based upon the closing bid price of the Common Stock, we were 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, should it be necessary, as part of the Company’s plan to regain compliance with Nasdaq rules.

On January 13, 2025, the Company received a letter issued by the Panel granting the Company’s request to continue its listing on Nasdaq until April 15, 2025 while the Company executes its plan to regain compliance with the requirements of Nasdaq Listing Rule 5550(b). Additionally, the Panel confirmed that the Company has regained compliance with the Minimum Bid Price Requirement, as set forth in Nasdaq Listing Rule 5550(a)(2), as a result of the reverse stock split the Company effected on December 12, 2024.

As disclosed in the Company’s Current Report on Form 8-K filed on April 14, 2025, on April 12, 2025, the Company entered into a master services agreement (the “Master Services Agreement”) with Velo3D, Inc. (OTC: VLDX) (“VLD”), a provider of additive manufacturing solutions, also referred to as 3D printing, pursuant to which VLD will 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 Class A common stock and 673,408 shares of non-voting Series A Convertible Preferred Stock, par value 0.00001 per share.

As a result of the transaction, and as of April 15, 2025, the Company believes it has stockholders’ equity of approximately $8.1 million and thereby satisfies the Equity Rule.

TABLE OF CONTENTS

Notwithstanding, the Company must await Nasdaq’s formal confirmation that it has evidenced compliance with the Equity Rule. Furthermore, if deemed compliant, Nasdaq will continue to monitor the Company to ensure its ongoing compliance with the Equity Rule and, if at the time of filing of the Company’s next periodic financial statements the Company does not evidence compliance with the Equity Rule, the Company may again be subject to delisting from Nasdaq.

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”). Unless otherwise noted, all information presented in this prospectus is presented on a post-split basis.

Going Concern Uncertainty

Our consolidated 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 losses of $34.9 million for the year ended December 31, 2024 and an accumulated deficit of $408.0 million as of December 31, 2024. Additionally, the Company used net cash of $16.6 million to fund its operating activities for the year ended December 31, 2024, and had cash and cash equivalents of $1.6 million as of December 31, 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 financial statements for the year ended December 31, 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 financial statements. The Company believes that its current level of cash and cash equivalents are not sufficient to fund commercial scale production and sale of its 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 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 opportunities to access additional capital through all 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.

Implications of Being a Smaller Reporting Company

As a company with less than $100 million of annual revenue in our most recently completed fiscal year and the market value of our stock held by non-affiliates as of June 30, 2024, was less than $700 million, we qualify as a “smaller reporting company” as defined in Rule 12b-2 of the Securities Exchange Act of 1934, as amended. A smaller reporting 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, reduced disclosure about our executive compensation arrangements and an exemption from the requirements to obtain a non-binding advisory vote on golden parachute arrangements. Accordingly, the information contained herein may be different from the information you receive from other public companies in which you hold stock.

TABLE OF CONTENTS

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 in this section and 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, 2024, filed with the SEC on April 1, 2025, 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 April 9, 2025 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. In that even, the price of our Common Stock could decline, and you could lose part or all of your investment.

We may not currently or in the future be able to continue as a going concern.

The financial statements incorporated by reference in this prospectus have been prepared on a going concern basis of accounting which assumes that we will continue as a going concern, and do not reflect any adjustments that might result if the Company is unable to continue as a going concern. The Company’s ability to continue as a going concern is dependent on the Company’s ability to generate revenues and raise capital. To date, the Company has not generated sufficient revenues to provide cash flows that enable the Company to finance its operations internally. In connection with an evaluation conducted by the Company’s management during the preparation of this report, management concluded that there were conditions and events 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 the financial statements included in this report.

The uncertainty regarding our ability to continue as a going concern could materially adversely affect our share price and our ability to service our indebtedness, raise new capital or enter into commercial transactions. To address these matters, the Company may take actions that materially and adversely affect our business, including significant reductions in research, development, administrative and commercial activities, reduction of our employee base, and ultimately curtailing or ceasing operations, any of which could materially adversely affect our business, financial condition, results of operations and share price. In addition, doubts about our ability to continue as a going concern could impact our relationships with customers, vendors and other third parties and our ability to obtain, maintain or renew contracts with them, or negatively impact our negotiating leverage with such parties, which could have a material adverse effect on our business, financial condition and results of operations. Furthermore, any loss of key personnel, employee attrition or material erosion of employee morale arising out of doubts about our ability to operate as a going concern could have a material adverse effect on our ability to effectively conduct our business and could impair our ability to execute our strategy and implement our business objectives, thereby having a material adverse effect on our business, financial condition and results of operations.

If we fail to comply with the continued listing requirements of Nasdaq we face possible delisting, which would result in a limited public market for our shares and make obtaining future debt or equity financing more difficult for us.

On March 27, 2024, the Company received a letter from the Listing Qualifications Staff of Nasdaq 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).

TABLE OF CONTENTS

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 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 was effective at the opening of trading on Nasdaq on December 13, 2024 (the “Effective Date”). On December 27, 2024, the Company’s Common Stock closed above the minimum bid price for ten consecutive trading days as required to regain compliance with the Minimum Bid Price Requirement.

As a result of the transaction, and as of the date of this filing, the Company believes it has stockholders’ equity of approximately $8.1 million and thereby satisfies the Equity Rule.

There can be no assurance that the Company will be able to regain compliance with the Minimum Bid Price Requirement or will otherwise be in compliance with other applicable Nasdaq listing rules, that the Company will be able to successfully implement a reverse stock split if it decides to pursue one, that the Panel will grant the Company’s request for a suspension of delisting on Nasdaq, or that the Company’s appeal of the delisting determination will be successful.

TABLE OF CONTENTS

If at the time of filing of the Company’s next periodic financial statements the Company does not evidence compliance with the Equity Rule, the Company may again be subject to delisting from Nasdaq. If the Common Stock loses its listing on the Nasdaq Capital Market, the Common Stock would likely trade in the over-the-counter market. If the Common Stock were to trade on the over-the-counter market, selling the Common Stock could be more difficult because smaller quantities of shares would likely be bought and sold, transactions could be delayed, and security analysts’ coverage of us may be reduced. In addition, in the event the Common Stock is delisted, broker-dealers have certain regulatory burdens imposed upon them, which may discourage broker-dealers from effecting transactions in the Common Stock, further limiting the liquidity of such shares. A determination that the Common Stock is a “penny stock” would require brokers trading in the Common Stock to adhere to even more stringent rules and possibly result in a reduced level of trading activity in the secondary trading market for the Common Stock. These factors could result in lower prices and larger spreads in the bid and ask prices for the Common Stock. Such delisting from the Nasdaq Capital Market and continued or further declines in the price of shares of the Common Stock could also greatly impair our ability to raise additional necessary capital through equity or debt financing, and could significantly increase the ownership dilution to stockholders caused by our issuing equity in financing or other transactions.

We need additional capital and any additional capital we seek may not be available in the amount or at the time we need it.

We need to raise funds in the future to execute our business plan. We may seek to raise additional capital to expand our business, pursue strategic investments, and take advantage of financing or other opportunities that we believe to be in our best interests and the interests of our stockholders. Additional capital may be raised through the sale of common or preferred equity or convertible debt securities, entry into debt facilities or other third-party funding arrangements. The sale of equity and convertible debt securities may result in dilution to our stockholders and those securities may have rights senior to those of the Common Stock. Agreements entered into in connection with such capital raising activities could contain covenants that would restrict our operations or require us to relinquish certain rights. Additional capital may not be available on reasonable terms, or at all. If we cannot timely raise any needed funds, we may be forced to reduce our operating expenses, which could adversely affect our ability to implement our long-term strategic roadmap and grow our business. Our ability to raise capital through the sale of securities may be limited by our inability to utilize a registration statement on Form S-3 to raise capital until March 2026 due to the late filing of our Annual Report on Form 10-K for the year ending December 31, 2023, the late filing of our Quarterly Report on Form 10-Q for the quarter ending March 31, 2024, the late filing of our Quarterly Report on Form 10-Q for the quarter ending June 30, 2024, and the late filing of our Current Report on Form 8-K dated March 20, 2025.

The market price of the Common Stock has been, and may continue to be, volatile, which could reduce the market price of the Common Stock.

The publicly traded shares of the Common Stock have experienced, and may experience in the future significant price and volume fluctuations. During the 12 months ended April 16, 2025, the market price of the Common Stock has ranged from a high of $28.56 per share to a low of $1.56 per share. This market volatility could reduce the market price of the Common Stock without regard to our operating performance. In addition, the trading price of the Common Stock could change significantly in response to actual or anticipated variations in our quarterly operating results, announcements by us or our competitors, factors affecting the space transportation industry generally, changes in national or regional economic conditions, changes in securities analysts’ estimates for us or our competitors’ or industry’s future performance or general market conditions, making it more difficult for shares of the Common Stock to be sold at a favorable price or at all. The market price of the Common Stock could also be reduced by general market price declines or market volatility in the future or future declines or volatility in the prices of stocks for companies in our industry.

Pursuant to the terms of the Master Services Agreement, we are required to recommend that our stockholders approve the conversion of all outstanding shares of our non-voting Series A Convertible Preferred Stock into shares of our Common Stock. We cannot guarantee that our stockholders will approve this matter.

Under the terms of the Master Services Agreement, we agreed to call and hold a meeting of our stockholders to obtain, among other things, the requisite approvals for the conversion of all outstanding shares of non-voting Series A Convertible Preferred Stock to be issued under the Master Services Agreement into shares of our Common Stock and to seek approval of a potential issuance of common stock in excess of 20% of the number of shares of common stock outstanding before the issuance of the stock under Nasdaq Listing Rule 5635(A)(1), in each case as required by the

TABLE OF CONTENTS

Nasdaq Stock Market LLC listing rules. If such approval is not obtained at that meeting, the Company agreed to seek to obtain such approvals at an annual or special stockholders meeting to be held at least every ninety (90) days thereafter until such approval is obtained, which would be time consuming and costly.

The issuance of Common Stock upon conversion of our outstanding non-voting Series A Convertible Preferred Stock will cause immediate and substantial dilution to existing shareholders.

As of the date of this Registration Statement on Form S-1, we had 673,408 outstanding shares of non-voting Series A Convertible Preferred Stock. If the Company’s stockholders approve the conversion of the Preferred Stock into Common Stock, the holder of the Series A Convertible Preferred Stock may, at its option, convert each of its shares of Preferred Stock into ten shares of Common Stock, subject to the limitations in the Certificate of Designations of Preferences, Rights and Limitations of Series A Convertible Preferred Stock (the “Certificate of Designations”), including that VLD hold no more than 9.99% of the outstanding shares of our Common Stock at any time. The conversion of the non-voting Series A Convertible Preferred Stock of the Company will cause significant dilution to the then holders of our Common Stock. In addition, the Common Stock issuable upon conversion of our outstanding non-voting Series A Convertible Preferred Stock may represent overhang that may also adversely affect the market price of our Common Stock. Overhang occurs when there is a greater supply of a company’s stock in the market than there is demand for that stock, which typically depresses a company’s stock price. If we experience overhang, any additional shares which the then holders of our Common Stock attempt to sell in the market will only further decrease the market price of our Common Stock.

USE OF PROCEEDS

We will not receive any of the proceeds from the sale of the Shares by the Selling Stockholders pursuant to this prospectus. We will bear all fees and expenses incident to our obligation to register such shares.

TABLE OF CONTENTS

SELLING STOCKHOLDERS

This prospectus covers the resale or other disposition by the Selling Stockholders identified in the table below of the Shares, consisting of up to an aggregate of 2,142,858 shares of Common Stock. The Selling Stockholders acquired the Inducement Warrants exercisable for the Shares in the transaction described above under the heading “Prospectus Summary—Warrant Inducement Transaction.”

The Inducement Warrants provide that the Selling Stockholders will not have the right to exercise any portion of the Inducement Warrants if such exercise would cause the aggregate number of shares of Common Stock beneficially owned by the applicable 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 exercise, as such percentage ownership is determined in accordance with the terms of the Warrants. By written notice to the Company, a Selling Stockholder may decrease or increase the Ownership Limitation to any other percentage, provided that in no event can the Ownership Limitation exceed 9.99%. Any such increase will not be effective until the 61st day after such notice is delivered to the Company by the Selling Stockholders.

The table below sets forth, as of April 17, 2025, the following information regarding the Selling Stockholders:

•	Name of the Selling Stockholders;

•	Number of shares of Common Stock beneficially owned by the Selling Stockholders prior to the exercise of the Inducement Warrants; and

•	Number of Inducement Warrants to purchase shares of Common Stock beneficially owned by the Selling Stockholders.

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 Stockholders has been furnished by or on behalf of the Selling Stockholders. We believe, based on information supplied by the Selling Stockholders, that except as may otherwise be indicated in the footnotes to the table below, the Selling Stockholders have sole voting and dispositive power with respect to the shares of Common Stock reported as beneficially owned by the Selling Stockholders. Because the Selling Stockholders 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 Stockholders upon termination of this offering. In addition, the Selling Stockholders 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 Stockholders will sell all of their respective 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 Stockholders 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 securities are directly held by Armistice Capital Master Fund Ltd., a Cayman Islands exempted company (the “Master Fund”), and may be deemed to be beneficially owned by: (i) Armistice Capital, LLC (“Armistice Capital”), as the investment manager of the Master Fund; and (ii) Steven Boyd, as the Managing Member of Armistice Capital. The warrants are subject to a beneficial ownership limitation of 4.99% (or, at the election of the Selling Stockholder, up to 9.99%), which such limitation restricts the Selling Stockholder from exercising that portion of the warrants that would result in the Selling Stockholder and its affiliates owning, after exercise, a number of shares of common stock in excess of the beneficial ownership limitation. The address of Armistice Capital Master Fund Ltd. is c/o Armistice Capital, LLC, 510 Madison Avenue, 7th Floor, New York, NY 10022.

PLAN OF DISTRIBUTION

The Selling Stockholders and any of their respective pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their securities covered hereby on Nasdaq or any other stock exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. The Selling Stockholders may use any one or more of the following methods when selling securities:

•	ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

•	block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•	purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

•	an exchange distribution in accordance with the rules of the applicable exchange;

•	privately negotiated transactions;

•	settlement of short sales;

•	in transactions through broker-dealers that agree with the applicable Selling Stockholder to sell a specified number of such securities at a stipulated price per security;

•	through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

•	a combination of any such methods of sale; or

•	any other method permitted pursuant to applicable law.

The Selling Stockholders may also sell securities under Rule 144 or any other exemption from registration under the Securities Act of 1933, as amended (the “Securities Act”), if available, rather than under this prospectus.

Broker-dealers engaged by the applicable Selling Stockholder may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the applicable Selling Stockholder (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2121; and in the case of a principal transaction a markup or markdown in compliance with FINRA Rule 2121.

In connection with the sale of the securities or interests therein, the applicable Selling Stockholder may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The applicable Selling Stockholder may also sell securities short and deliver these securities to close out its short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The applicable Selling Stockholder may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The applicable 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 Stockholders 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.

The Company is required to pay certain fees and expenses incurred by the Company incident to the registration of the securities. The Company has agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities.

We agreed to keep this prospectus effective until the earlier of (i) the date on which the securities may be resold by the Selling Stockholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in compliance with the current public information

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.

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 sell and issue to such stockholder (i) pre-funded warrants (the “Pre-Funded Warrants”) to purchase up to 357,143 shares of Common Stock, (ii) Class A Warrants to purchase up to 714,286 shares of Common Stock and (iii) Class B Warrants to purchase up to 357,143 shares of 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 $8.05 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 to purchase up to 35,715 shares of Common Stock at an exercise price of $8.855, 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 December 31, 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 $7.45 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.

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 $7.41 per share. The conversion price and the number of shares of Common

In addition to the Subsequent Convertible Note, the Company agreed to issue to SIV warrants to purchase up to 463,223 shares of Common Stock with an exercise price of $7.41 per share (the “SIV Warrants”), of which warrants to purchase 269,950 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 193,273 shares of 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 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 4.99% of the number of shares of 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 December 13, 2024, the Company entered into the Loan Agreement with J.J. Astor & Co. pursuant to which the Company issued to J.J. Astor & Co. the Lender Warrants to purchase up to 28,572 shares of Common Stock at an exercise price of $5.92. The exercise price and the number of shares of Common Stock issuable upon exercise of the Lender 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.

Momentus entered into a Registration Rights Agreement with J.J. Astor & Co. that required the Company to file a resale shelf registration statement registering the resale of the shares of Common Stock issuable upon exercise of the Lender Warrants within 31 calendar days following the closing date.

None of the Lender Warrants can be converted or exercised if it would cause the aggregate number of shares of Common Stock beneficially owned by J.J. Astor & Co. (together with its affiliates) to exceed 4.99% of the number of shares of Common Stock outstanding immediately after giving effect to the exercise. By written notice, J.J. Astor & Co. may from time to time increase or decrease this ownership limitation to any other percentage up to 9.99%, provided, that any such increase will not be effective until the 61st day after such notice is delivered to the Company.

The Company has agreed to call a special meeting of shareholders by no later than March 13, 2025 to obtain shareholder approval.

Best Efforts Offering

On February 11, 2025, the Company consummated a “best efforts” public placement pursuant of an aggregate of (i) 300,000 shares (the “Shares”) of Common Stock, (ii) 973,886 pre-funded warrants (the “Pre-Funded Warrants”) to purchase up to 973,886 shares of Common Stock, and (iii) 1,273,886 Common Stock purchase warrants (“Common Warrants”) to purchase up to 1,273,886 shares of Common Stock (the “Common Stock Shares”). Each share of Common Stock, or a Pre-Funded Warrant in lieu thereof, was sold together with an accompanying Common Warrant to purchase one share of Common Stock.

The public offering price for each share of Common Stock and one accompanying Common Warrant was $3.92499. The public offering price of each Pre-Funded Warrant and one accompanying Common Warrant was $3.925, which equals the price at which one share of Common Stock and accompanying Common Warrant was sold to the public in this offering, minus $0.00001. The exercise price of each Pre-Funded Warrant is $0.00001 per share. Each Common Warrant offered in the Offering is exercisable for one share of Common Stock and has an initial exercise price equal to $3.80. The exercise price of the Common Warrants and the Pre-Funded Warrants and number of shares of Common Stock issuable upon exercise will adjust in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events.

In connection with the offering, on February 10, 2025, the Company entered into a Placement Agency Agreement with A.G.P./Alliance Global Partners (“A.G.P.” or the “Placement Agent”), pursuant to which the Placement Agent agreed to act as Placement Agent on a reasonable “best efforts” basis in connection with the Offering. The Company paid the Placement Agent a cash fee equal to 7.0% of the gross proceeds raised in the Offering. In addition, the Company has also agreed to reimburse the Placement Agent for legal expenses incurred by it in connection with the Offering in an amount not to exceed $95,000 and up to $10,000 for certain reasonable non-accountable fees and expenses. In addition, the Placement Agent will receive warrants (the “Placement Agent Warrants”) to purchase such number of shares of Common Stock equal to 5.0% of the aggregate number of shares of Common Stock sold in the Offering, or an aggregate of 63,694 shares of Common Stock. The Placement Agent Warrants will have substantially the same terms as the Common Warrants, except that the Placement Agent Warrants will have an exercise price of $4.3175 per share (representing 110% of the offering price per share of Common Stock and accompanying Common Warrant) and will expire five years from the commencement of the sales pursuant to the Offering.

In connection with the Offering, on February 10, 2025, the Company entered into a securities purchase agreement (the “Purchase Agreement”) with a single institutional investor (the “Investor”), pursuant to which the Company agreed not to effect or enter into an agreement to effect any issuance by the Company or any of its subsidiaries of shares of Common Stock or Common Stock equivalents for a period of thirty (30) days and will not effect or enter into an agreement to effect any issuance by the Company or any of its subsidiaries of shares of Common Stock or Common Stock Equivalents (or a combination of units thereof) involving a Variable Rate Transaction (as defined in the Purchase Agreement) for a period of six (6) months after the Closing Date, subject to certain exceptions.

The Investor is the holder of certain common stock purchase warrants, issued on each of (i) September 17, 2024 (the “Class A September 2024 Warrant” and the “Class B September 2024 Warrant”), (ii) October 24, 2024 (the “October 2024 Warrant”), and (iii) 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”) to purchase shares of Common Stock.

In connection with the Offering, on February 10, 2025, the Company entered into an amendment to the Warrants (the “Amendment to Common Stock Purchase Warrants”) with the Investor, pursuant to which the exercise price per share of the Common Stock under each Warrant shall be $3.80, subject to adjustment The warrant amendment is

subject to stockholder approval, and the warrants shall expire five years from the date stockholder approval is obtained. If stockholder approval is not obtained by the date that is six (6) months following the initial date of issuance of these Warrants, then the exercise price of the Warrants will automatically be reduced to the Minimum Price (as defined in Nasdaq Listing Rule 5635(d)) of the Common Stock on the date that is six (6) months following the initial date of issuance of the Warrants and the Warrants will expire five years following the date that is six (6) months following the initial date of issuance of the Warrants.

Velo3D Transaction

On April 12, 2025, the Company entered into a master services agreement (the “Master Services Agreement”) with Velo3D, Inc. (OTC: VLDX) (“VLD”), a provider of additive manufacturing solutions also referred to as 3D printing. Pursuant to the Master Services Agreement, VLD will provide services to design and produce components and systems that will be utilized by Momentus or its customers in its spacecraft, systems, and components. According to the terms of the Master Services Agreement, Momentus is entitled to services equal to the equivalent capacity of two VLD Sapphire XC 3D metal printers (or successor or comparable printers) (the “Equivalent Capacity”). Momentus will have first priority to utilize the Equivalent Capacity, and VLD will ensure the Equivalent Capacity is available for use as and when required by Momentus.

If and when the Equivalent Capacity is not utilized by Momentus, VLD may use the Equivalent Capacity to provide services to other customers. According to the Master Services Agreement, Momentus will be compensated for such use based on a formula equal to 20% of $3 million less service fees attributed to Momentus in the first year and 50% of $3 million less service fees attributed to Momentus in each subsequent year of the agreement. Such compensation shall reduce the amount in the Prepaid Reserve, as described in the Master Services Agreement. The term of the Master Services Agreement is five years unless terminated earlier in accordance with its terms.

In exchange for the services, Momentus issued an aggregate of 477,455 shares of Common Stock and 673,408 shares of non voting Series A Convertible Preferred Stock, par value 0.00001 per share (the “Preferred Stock”). Each share of Preferred Stock is convertible into ten shares of Common Stock, subject to the limitations in the Certificate of Designations of Preferences, Rights and Limitations of Series A Convertible Preferred Stock (the “Certificate of Designations”), including that VLD hold no more than 9.99% of the outstanding shares of Momentus’s Common Stock at any time.

The undersigned registrant hereby undertakes to

(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.

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.

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.
