EXPLANATORY NOTE

Momentus Inc. (“Momentus”) is filing this Amendment No. 1 on Form 10-K/A (this “Amendment”) to provide a revised Exhibit Index in Part IV, Item 15 of its Annual Report on Form 10-K for the fiscal year ended December 31, 2024, as filed with the Securities and Exchange Commission (the “SEC”) on April 1, 2025 (the “Original 10-K”), including removing Exhibit 23.2 (Armanino’s consent), and to file Exhibit 23.1 (Frank Rimerman’s consent), which was inadvertently omitted from the Original 10-K filing. Accordingly, the Exhibit Index has been amended and restated in its entirety to reflect these changes. Momentus is also providing new certifications from its principal executive officer and principal financial officer as required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended.

Except as described above, Momentus has not modified or updated any disclosures contained in the Original 10-K. Accordingly, this Amendment does not reflect events occurring after the date of filing of the Original 10-K and therefore continues to speak only as of the date of the Original 10-K.
