---

On December 3, 2025, the Board of Directors (the "Board") of Momentus Inc., a Delaware corporation (the "Company") approved a reverse stock split of the Company's issued and outstanding shares of Class A Common Stock, $0.00001 par value per share (the "Common Stock"), at a ratio of 1-for-17.85 (the "Reverse Stock Split"). The Reverse Stock Split will be effective as of 5:00 p.m. Eastern Time on Wednesday, December 17, 2025 (the "Effective Date"), with the Common Stock trading on the Nasdaq Capital Market on a reverse-split adjusted basis under the Company's existing trading symbol, "MNTS," at the market open on Thursday, December 18, 2025.

#### Reason for the Reverse Stock Split
The Company is effecting the Reverse Stock Split to satisfy the $1.00 minimum bid price requirement, as set forth in Listing Rule 5450(a)(1) (the "Minimum Bid Requirement"), for continued listing on the Nasdaq Stock Market LLC ("Nasdaq") exchange.

#### Effects of the Reverse Stock Split
*Effective Date; Symbol; CUSIP Number*. The Reverse Stock Split becomes effective with Nasdaq and the Common Stock will begin trading on a split-adjusted basis at the open of business on the day following the Effective Date. In connection with the Reverse Stock Split, the CUSIP number for the Common Stock will change to 60879E408. The trading symbol for the Company, MNTS, will not be changed.

*Split Adjustment; Treatment of Fractional Shares*. On the Effective Date, the total number of shares of Common Stock held by each stockholder of the Company will be converted automatically into (i) the number of issued and outstanding shares of Common Stock held by each such stockholder immediately prior to the Reverse Stock Split divided by (ii) seventeen and eighty-five hundredths (17.85). Any fractional share of Common Stock that would otherwise result from the Reverse Stock Split will be rounded to a whole share and, as such, any stockholder who otherwise would have held a fractional share after giving effect to the Reverse Stock Split will instead hold one whole share of the post-Reverse Stock Split Common Stock after giving effect to the Reverse Stock Split. As a result, no fractional shares will be issued in connection with the Reverse Stock Split and no cash or other consideration will be paid in connection with any fractional shares that would otherwise have resulted from the Reverse Stock Split. The Company intends to treat stockholders holding shares of Common Stock in "street name" (that is, held through a bank, broker or other nominee) in the same manner as stockholders of record whose shares of Common Stock are registered in their names. Banks, brokers or other nominees will be instructed to effect the Reverse Stock Split for their beneficial holders holding shares of our Common Stock in "street name;" however, these banks, brokers or other nominees may apply their own specific procedures for processing the Reverse Stock Split.

Also on the Effective Date, all options, warrants and other convertible securities of the Company outstanding immediately prior to the Reverse Stock Split will be adjusted by dividing the number of shares of Common Stock into which the options, warrants and other convertible securities are exercisable or convertible by 17.85 and multiplying the exercise or conversion price thereof by seventeen and eighty-five hundredths (17.85), all in accordance with the terms of the plans, agreements or arrangements governing such options, warrants and other convertible securities and subject to rounding to the nearest whole share. Such proportional adjustments will also be made to the number of shares and restricted stock units issued and issuable under the Company's equity compensation plan.

*Certificated and Non-Certificated Shares*. Stockholders who are holding their shares in electronic form at brokerage firms do not need to take any action, as the effect of the Reverse Stock Split will automatically be reflected in their brokerage accounts.

------

After the Reverse Stock Split becomes effective, stockholders holding paper certificates may (but are not required to) send the certificates to the Company's transfer agent and registrar, Continental Stock Transfer & Trust Company ("Continental") at the address set forth below. Continental will issue a new stock certificate reflecting the Reverse Stock Split to each requesting stockholder. Continental can be contacted at (212) 509-4000 and (800) 509-5586.

Continental Stock Transfer & Trust Company

1 State Street, 30<sup>th</sup> Floor

New York, New York 10004

*Certificate of Amendment*. The Company will effect the Reverse Stock Split pursuant to the Company's filing of a certificate of amendment to the Company's certificate of incorporation (the "Certificate") with the Delaware Secretary of State effective 5:00 p.m. Eastern Time, on December 17, 2025, in accordance with Delaware law. A copy of the Certificate is attached hereto as Exhibit 3.1 and is incorporated herein by reference.

*Stockholder Approval*. At the Company's Special Meeting held on September 17, 2025, the stockholders approved a proposal to grant the Board of Directors discretion to implement a reverse stock split in a range of one-for-five (1-for-5) up to one-for-seventeen and eighty-five hundredths (1-for-17.85). As such the Reverse Stock Split was approved in accordance with Delaware law.

*Capitalization*. As of December 1, 2025, there were 24,939,640 shares of Common Stock outstanding. As a result of the Reverse Stock Split, there will be approximately 1,397,179 shares of Common Stock outstanding (subject to adjustment due to the effect of rounding fractional shares into whole shares). The Reverse Stock Split will not have any effect on the stated par value of the Common Stock. The total number of the Company's authorized shares of Common Stock and Preferred Stock shall not be affected by the foregoing.

Immediately after the Reverse Stock Split, each stockholder's relative ownership in the interest in the Company and proportional voting power will remain virtually unchanged except for minor changes and adjustments that will result from rounding fractional shares into whole shares.

 **Exhibit 99.2**<br>

![](image00001.jpg)

#### Momentus Inc. Announces Reverse Stock Split
SAN JOSE, CA – December 15, 2025 – Momentus Inc. (NASDAQ: MNTS) ("Momentus" or the "Company"), a U.S. commercial space company that offers satellite buses, transportation and other in-space infrastructure services, today announced it has effectuated a 1-for-17.85 reverse stock split (the "Reverse Stock Split") of its Class A common stock (the "Common Stock") that will become effective on December 17, 2025 at 5:00 p.m. Eastern Time. The Company's Common Stock will continue to trade on the Nasdaq Global Select Market ("Nasdaq") under the symbol "MNTS" and will begin trading on a split-adjusted basis at the opening of the market on December 18, 2025. The new CUSIP number for the Common Stock following the Reverse Stock Split will be 60879E408.

The Reverse Stock Split was approved by the Company's stockholders at the special meeting of the stockholders on September 17, 2025. As a result of the Reverse Stock Split, every 17.85 shares of Common Stock issued and outstanding will be automatically combined into one share of Common Stock. The Reverse Stock Split will proportionately reduce the number of outstanding shares of Common Stock from approximately 25 million shares to approximately 1.4 million shares and the ownership percentage of each stockholder will remain unchanged other than as a result of fractional shares. The Company's public warrants trading on Nasdaq under the existing symbol "MNTSW," and outstanding equity-based awards and shares or share units issued under the Company's benefit plans, including applicable exercise prices, will be proportionately adjusted.

No fractional shares of Common Stock will be issued in connection with the Reverse Stock Split. Stockholders that would hold a fractional share of Common Stock as a result of the Reverse Stock Split will have such fractional shares of Common Stock rounded up to the nearest whole share of Common Stock.

To effectuate the Reverse Stock Split, the Company filed the Certificate of Amendment to its Second Amended and Restated Certificate of Incorporation, as amended, which was accepted for filing by the Secretary of State of the State of Delaware on December 15, 2025. There will be no change to the total number of authorized shares of Common Stock as set forth in the Second Amended and Restated Certificate of Incorporation of the Company, as amended.

Among other considerations, the Reverse Stock Split is intended to maintain the Company's compliance with the minimum bid price requirement for maintaining the listing of its Common Stock on Nasdaq, and to make the bid price more attractive to a broader group of institutional and retail investors. Nasdaq requires, among other things, that a listing company's common stock maintain a minimum bid price of at least $1.00 per share.
