Momentus Awarded NASA Contract to Provide Flight and Payload Integration Services

Momentus Inc. (NASDAQ: MNTS)("Momentus" or the "Company"), a leading provider of in-space transportation services, is pleased to announce that it has been awarded a NASA indefinite-delivery/indefinite-quantity (ID/IQ) base contract award with a performance period of five years to provide flight and payload integration services to advance technologies and procedures for operating in space.

Under the ID/IQ contract awarded by NASA, Momentus is among 15 companies selected that are eligible to receive task or delivery orders to provide in-space transportation services, including propulsion systems and orbital transfer capabilities, to facilitate the deployment of satellites, payloads, and scientific instruments.

"We are honored to be selected by NASA for this important opportunity to support the United States' efforts in space," said John Rood, CEO of Momentus.

The contracts will be managed by NASA's Flight Opportunities program, in collaboration with the Small Spacecraft Technology program, both part of the agency's Space Technology Mission Directorate.

Momentus' Vigoride vehicle offers flexible and reliable transportation solutions for a wide range of mission profiles at various orbits. The company's technology includes water plasma thrusters, which are safer and more environmentally friendly than traditional chemical propulsion systems and flexible solar arrays to allow deployment and retraction of critical power generation capabilities.

"We look forward to collaborating closely with NASA and contributing to the success of their ambitious space programs," added Rob Schwarz, Momentus' Chief Technology Officer.
