Momentus Inc. (NASDAQ: MNTS) (“Momentus” or the "Company”), a U.S. commercial space company that offers transportation and other in-space infrastructure services, today announced that Dawn Harms, Chief Revenue Officer, will retire effective Dec. 31, 2022.

"We express our heartfelt thanks to Dawn for her leadership, resilience, and dedication to our company and our customers,” said Momentus Chief Executive Officer John Rood. “Dawn’s contributions were integral to the transformation of our Company, particularly as we started trading on the NASDAQ last August, and as we flew our first demonstration mission in May 2022. On behalf of the entire team, we wish Dawn the best in her well-earned retirement.”

Harms joined Momentus in 2019 as Chief Revenue Officer, leading the Company’s commercial sales strategy. From January 2021 to August 2021, she served as interim Chief Executive Officer, and she returned to the CRO role at the conclusion of her interim CEO tenure.

“I’ve enjoyed supporting the transformation of the Company from startup status into a public company,” said Harms. “I am confident that Momentus will thrive as it works to bring foundational space infrastructure services to market.”

Momentus plans to announce a successor to Harms later this year.
