Momentus Inc. reported first-quarter 2026 service revenue of $3.2 million, up sharply from $0.3 million a year earlier, driven by hosted payload and engineering services, largely for U.S. government customers. The company still posted a net loss of $9.5 million, but cash and equivalents rose to $23.5 million as of March 31, 2026, supported by $16.7 million in net financing inflows. Additional raises after quarter-end, including a $5.0 million private placement and about $10.5 million of Class A stock sales in May 2026, led management to conclude that prior substantial doubt about its ability to continue as a going concern no longer exists. Shares outstanding reached 9,992,398 Class A shares as of May 13, 2026 following conversions of preferred and convertible notes and warrant exercises.
Momentus Inc. released a shareholder letter and press release outlining sharp expected growth and a stronger balance sheet. The company forecasts $10.0 million in 2026 revenue, a roughly 9x increase from $1.1 million in 2025, largely from milestone payments on existing NASA and defense contracts.
As of April 23, 2026, Momentus held $26.2 million in cash, up from $12.8 million at 2025 year-end, and reports having no outstanding debt after retiring $1.35 million of convertible notes. A recent private placement raised about $5 million through the sale of 1,333,334 shares or equivalents.
The letter highlights successful launch and operation of the Vigoride 7 orbital service vehicle with 10 payloads, a sold-out Vigoride 8 mission planned for 2027, and active contracts including approximately $4.2 million with DARPA and $1.9 million with SpaceWERX. Momentus has expanded into a 61,100‑square‑foot San Jose facility to support growing demand from defense and NASA programs.
