Stable Road Acquisition Corp. Information Request Form

(a) Stable Road’s acquistion target, Momentus’s 2019 test of its key technology, a water plasma thruster, had failed to meet Momentus’s own public and internal pre-launch criteria for success, and was conducted on a prototype that was not designed to generate commercially significant amounts of thrust; (b) the U.S. government had conveyed that it considered Momentus’s Chief Executive Officer a national security threat, jeopardizing his continued leadership of Momentus and Momentus’s launch schedule and business prospects; (c) consequently, the revenue projections and business and operational plans provided to investors regarding Momentus and the commercial viability and timeline of its products were materially false and misleading and lacked a reasonable basis in fact; and (d) Stable Road had failed to conduct appropriate due diligence of Momentus and its business operations and defendants had materially misrepresented the due diligence activities being conducted by Stable Road executives and its sponsor in connection with the merger.
