Momentus Inc. has entered into a securities purchase agreement with a single existing institutional investor to sell 925,926 shares of common stock (or equivalents) and warrants to purchase up to 925,926 additional shares. The transaction is being conducted as an at-the-market offering under Nasdaq rules, resulting in gross proceeds of approximately $5.0 million. The company expects to use the net proceeds to fund working capital, mission operations for its Vigoride orbital service vehicles and ongoing technology development initiatives.

In partnership with Velo3D, Momentus has developed an advanced, metal 3D-printed fuel tank scheduled for flight testing on its upcoming Vigoride-7 mission. The tank was produced using Velo3D’s fully integrated printing platform, featuring Flow print preparation software, Sapphire printers and Assure quality assurance. By leveraging additive manufacturing, Momentus designed complex internal geometries that reduce part count and overall mass, enhancing propulsion efficiency and mission reliability in low-earth orbit operations.

The successful fabrication of a mission-critical component via additive manufacturing marks a strategic inflection point for Momentus’s supply chain. Traditional space-rated fuel tanks typically carry high costs and lead times of 12 to 18 months; the new process can compress production timelines by up to 40% and lower inventory carrying costs. Momentus plans to qualify as a supplier for third-party satellite integrators, potentially opening a new revenue stream worth an estimated $10 million annually by 2027, based on industry demand forecasts.

CEO John Rood highlighted that flight testing on Vigoride-7 will validate design assumptions and pave the way for broader commercial adoption of additively manufactured components. Velo3D CEO Arun Jeldi noted that the partnership underscores the platform’s ability to meet stringent aerospace performance requirements. Looking ahead, Momentus intends to integrate additional 3D-printed components—such as valve housings and bracketry—into its Vigoride series, with the goal of reducing overall spacecraft production costs by 15% over the next two years.
