Momentus Inc.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q (this “Form 10-Q”), including, without limitation, statements under the headings “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended, (the “Exchange Act”). Generally, statements that are not historical facts, including statements concerning Momentus Inc.’s (the “Company,” “Momentus,” “we,” “us,” or “our”) possible or assumed future actions, business strategies, events, or results of operations, are forward-looking statements. These forward-looking statements can be identified by the use of forward-looking terminology, including the words “believes,” “estimates,” “anticipates,” “expects,” “intends,” “plans,” “may,” “will,” “potential,” “projects,” “predicts,” “continue,” or “should,” or, in each case, their negative or other variations or comparable terminology, but the absence of these words does not mean that a statement is not forward-looking. There can be no assurance that actual results will not materially differ from expectations.

The forward-looking statements contained in this Form 10-Q are based on our current expectations and beliefs concerning future developments and their potential effects on us. Future developments affecting us may not be those that we have anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control) and other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, without limitation, the ability of the Company to raise additional capital to finance its longer-term business plan; the ability of the Company to obtain licenses and government approvals for its missions, which are essential to its operations; the ability of the Company to effectively market and sell satellites and satellite components; the ability to market and sell transportation services and planned in-orbit services; the ability of the Company to protect its intellectual property and trade secrets; the development of markets for small satellites and satellite transport and in-orbit services; the ability of the Company to develop, test and validate its technology, including its water plasma propulsion technology and Tape Spring Solar Array; delays or impediments that the Company may face in the development, manufacture and deployment of next generation satellite transport systems; the ability of the Company to convert backlog or inbound inquiries into revenue; changes in applicable laws or regulations and extensive and evolving government regulations that impact operations and business, including export control license requirements; the ability to attract or maintain a qualified workforce with the required security clearances and requisite skills; level of product service or product or launch failures or delays that could lead customers to use competitors’ services; investigations, claims, disputes, enforcement actions, litigation and/or other regulatory or legal proceedings; the possibility that the Company may be adversely affected by other economic, business, and/or competitive factors; and/or other risks and uncertainties described under Part II, Item 1A: “Risk Factors,” in this Form 10-Q and under Part I, Item 1A in our Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (the

“SEC”) on March 31, 2026. Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. We undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise, except as may be required under applicable securities laws. These risks and others described under Part II, Item 1A: “Risk Factors,” in this Form 10-Q and under Part I, Item 1A in our Annual Report on Form 10-K filed with the SEC on March 31, 2026, may not be exhaustive.

By their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that may or may not occur in the future. We caution you that forward-looking statements are not guarantees of future performance and that our actual results of operations, financial condition and liquidity, and developments in the industry in which we operate may differ materially from those made in or suggested by the forward-looking statements contained in this Form 10-Q. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements. In addition, even if our results or operations, financial condition and liquidity, and developments in the industry in which we operate are consistent with the forward-looking statements contained in this Form 10-Q, those results or developments may not be indicative of results or developments in subsequent periods.
