Momentus Awarded Innovation Research Contract from U.S. Defense Department’s Space Development Agency

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, has signed a contract with the U.S. Defense Department’s Space Development Agency (SDA) for a Small Business Innovation Research Award, "Orbital Service Vehicle Enhancements to Meet Department of Defense (DoD) Mission Requirements.”

Under this award, Momentus will tailor the capabilities of its Vigoride Orbital Service Vehicle to support a full range of DoD payloads and mission requirements. The additional capabilities will be developed to a Critical Design Review maturity, setting the stage for a rapid transition to an in-space flight demonstration.

The first contract action is valued at $746,073 with an option to add an additional $1,196,404 for further work.

“Vigoride’s flexibility, payload capacity, and power make it well-positioned to support a range of national security missions like space situational awareness, surveillance, reconnaissance, and other priorities,” said Momentus Chief Executive Officer John Rood. “We’re delighted by the opportunity to make improvements to Vigoride, so it is tailored to support SDA and DoD’s growing needs for capable space systems to meet the requirements of their national security missions.”

In addition to the Vigoride Orbital Service Vehicle, Momentus is now also offering its M-1000 satellite bus, which is based on the space-proven Vigoride. The M-1000 bus offers significant advantages to commercial and government customers, such as its high power - up to 3 kW of peak power - large payload capacity, flexible configuration, speed from requirements to delivery on-orbit, and low cost. Momentus has offered the M-1000 satellite bus to both commercial constellation providers and to the U.S. Government.
