October 26, 2020 – Santa Clara, CA – Momentus Inc. (“Momentus” or the “Company”), a
commercial space company providing in-space infrastructure services, and Gran Systems, a
newspace service provider for Taiwainese and Southeast Asia, today announced a service
agreement for Gran System’s 2U CubeSat NUTSAT to fly on Momentus’ December 2020
Vigoride demo mission.

The 2U NUTSAT was designed by the National Formosa University with the backing of the
National Space Organization (NSPO) in Taiwan. One of the three NSPO cubesats launching
this year, NUTSAT is a systems engineering training education program integrating an ADS-B
receiver onto the cubeSat to demonstrate and enhance commercial aviation safety technology.
NUTSAT is the first of the three cubesats to go for the launch integration.

“We are pleased that Momentus will accommodate NUTSAT,” said Kaung-Han Ke, CEO of
Gran Systems. “NUTSAT was shipped and delivered to Momentus the same hour that
Momentus made a big announcement which upped their profile in investor relations, and we are
very happy to be onboard.”

“This is the first NSPO cubesat mission that Momentus will support,” said Mikhail Kokorich, CEO
of Momentus. “We are thrilled to be expanding business opportunities and growing with the
Taiwanese newspace sector where our technology is uniquely positioned.”
