EXPLANATORY NOTE

This Amendment No. 4 (this “Amendment No. 4”) to the Statement on Schedule 13D (as amended, the “Statement”) is being filed with the Securities and Exchange Commission (the “Commission”) relating to the Class A Common Stock, par value $0.00001 per share (the “Shares”) of Momentus, Inc., a corporation organized under the laws of the state of Delaware (the “Issuer”). This Amendment amends and supplements the Statement originally filed on October 8, 2021 with the Commission. Unless otherwise defined herein, capitalized terms used herein shall have the meanings ascribed thereto in the Statement. Except as otherwise provided herein, each Item of the Schedule 13D remains unchanged.

Item 4.

Interest in Securities of the Issuer

Item 4 of the Statement is hereby supplemented as follows:

The Reporting Persons acquired the Shares based on the Reporting Persons’ belief that the Shares, when acquired, represented an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of Shares at prices that would make the purchase or sale of Shares desirable, the Reporting Persons may endeavor to increase or decrease their position in the Issuer through, among other things, the purchase or sale of Shares on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable.

Previously, the Reporting Persons have engaged with members of the Issuer’s Board of Directors (the “Board”) and management team to share their serious concerns with the trajectory of the Issuer. The Reporting Persons have appreciated the Board’s willingness to engage in meaningful discussions to date.

In communications with management and the Board of the Issuer, the Reporting Persons have requested that the Issuer immediately appoint, subject to customary onboarding procedures, Mr. Sloss to the Board to ensure that there is a direct stockholder representative in the boardroom and requested that the Issuer provide certain information regarding the Issuer’s capital expenditures, operational expenditures, plans to raise capital and growth forecasts.

The Reporting Persons hope to continue to engage constructively with the Board and management, but the Reporting Persons intend to closely monitor their investment in the Issuer and will continue to evaluate all potential courses of action to protect their interests and the interest of all stockholders of the Issuer.

No Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon or in connection with completion of, or following, any of the actions discussed herein. The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Depending on various factors including, without limitation, the Issuer’s financial position and investment strategy, the price levels of the Shares, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, continuing to engage in communications with management and the Board of the Issuer, engaging in discussions with stockholders of the Issuer or other third parties about the Issuer and the Reporting Persons’ investment, including potential business combinations or dispositions involving the Issuer or certain of its businesses, making recommendations or proposals to the Issuer concerning changes to the capitalization, ownership structure, board structure (including Board composition), potential business combinations or dispositions involving the Issuer or certain of its businesses, or suggestions for improving the Issuer’s financial and/or operational performance, purchasing additional Shares, selling some or all of their Shares, engaging in short selling of or any hedging or similar transaction with respect to the Shares, including swaps and other derivative instruments, or changing their intention with respect to any and all matters referred to in Item 4.
