Momentus Inc. (Nasdaq: MNTS) is a commercial space infrastructure company providing in-space transportation and services to satellite operators and other space customers. The company went public in 2021 through a merger with Stable Road Acquisition Corp., a blank-check vehicle sponsored by Stable Road Capital. The transaction attracted significant regulatory attention: the SEC brought enforcement actions against both Momentus and Stable Road, which settled charges tied to allegedly misleading investor disclosures about the company's propulsion technology and a national-security review of its former chief executive. The S-1 filed in September 2021 registered shares issued in connection with the completed merger. Sign up on SpacDesk for full filing history, deal analytics, and trading data on MNTS.
