Stable Road Urges All Stockholders to Vote Today to Approve Extension Amendment Proposal

Stable Road Acquisition Corp. (NASDAQ: SRAC, SRACU, and SRACW) (“Stable Road” or the “Company”) reminds every stockholder to vote their shares in favor of the proposal (the “Extension Amendment Proposal”) to allow the Company more time to complete its proposed business combination with Momentus Inc. (“Momentus”) by extending the date by which the Company has to consummate the proposed business combination with Momentus from May 13, 2021 to August 13, 2021. It is strongly recommended that stockholders complete their proxy card before the special meeting of stockholders (the “Special Meeting”), which will be held virtually on May 6, 2021 at 11:00am ET.

If the Extension Amendment Proposal is not approved, the Company will be unable to consummate the proposed business combination with Momentus and Stable Road may need to be dissolved. In such an event, your shares would be redeemed for approximately $10.03 per share.

The Extension Amendment Proposal requires approval by the affirmative vote of the holders of at least 65% of the outstanding shares of Class A common stock and Class B common stock, voting as a single class. If stockholders do not vote, this will have the same effect as a vote against the extension amendment.

“We appreciate the overwhelming support for the Extension Amendment Proposal that preliminary early voting results have indicated. However, in order to meet the required threshold for the Extension Amendment Proposal to be approved, more stockholders who owned shares of Class A common stock or Class B common stock on March 22, 2021 must vote. Every vote is important, no matter how many shares you own,” said Brian Kabot, Chairman and Chief Executive Officer of Stable Road.

Stable Road strongly encourages and recommends that stockholders of record as of March 22, 2021 complete and return their proxy card, voting “FOR” the Extension Amendment Proposal and “FOR” the other proposals set forth in the proxy statement for the Special Meeting, as soon as possible to prevent an adjournment of the Annual Meeting and ensure that all shares are represented at the Special Meeting.
