Momentus Inc. has entered into a securities purchase agreement with a single existing institutional investor for the purchase and sale of 925,926 shares of common stock (or common stock equivalents) and warrants to purchase up to 925,926 shares, raising $5.0 million through an at-the-market facility under Nasdaq rules. The funds are earmarked for advancing the Vigoride orbital service vehicle program, supporting mission preparation costs and supply-chain development. The offering is expected to close upon satisfaction of customary closing conditions and regulatory approvals.

Momentus, in collaboration with Velo3D, has developed an advanced metal additive manufactured fuel tank slated for in-orbit testing aboard its Vigoride-7 mission. Utilizing Velo3D’s Sapphire® printers and Flow™ software, the tank features complex internal geometries and weight savings of up to 20% compared to traditionally fabricated counterparts. The successful demonstration will validate reduced production timelines—from months to weeks—and pave the way for Momentus to qualify as a supplier of space-rated fuel tanks for commercial and government customers.

According to CEO John Rood, the Vigoride-7 fuel tank milestone underscores the strategic value of Momentus’s partnership with Velo3D, positioning the company to diversify its revenue streams by offering additively manufactured components. Velo3D CEO Arun Jeldi noted that the collaboration highlights how integrated additive workflows can deliver performance and reliability in demanding space environments. Looking ahead, Momentus plans to leverage this technology to shorten development cycles by 50%, reduce component costs by an estimated 30%, and enhance the resilience of its orbital service vehicles on future missions.
