Momentus has entered into a securities purchase agreement with a single existing institutional investor to sell 925,926 shares of its common stock (or equivalents) and warrants to purchase up to 925,926 additional shares. The transaction, conducted at-the-market under Nasdaq rules, is expected to generate gross proceeds of approximately $5.0 million. Proceeds will be used to fund ongoing operations, accelerate product development and support the upcoming Vigoride-7 mission. The financing represents a 7.5% increase in outstanding shares on a fully diluted basis, and the warrants carry a five-year term, reinforcing the investor’s confidence in Momentus’s long-term growth trajectory.

Momentus, in collaboration with Velo3D, has developed an advanced metal additive manufactured fuel tank slated for flight testing aboard its Vigoride-7 Orbital Service Vehicle later this year. Utilizing Velo3D’s Sapphire® printer and Flow™ software, the tank features complex internal cooling channels and optimized wall thicknesses that reduce weight by 20% compared with traditionally machined designs. This represents a strategic milestone in qualifying additive manufacturing for mission-critical spacecraft components, with estimated production lead times cut by 50% and cost savings of up to 30%. Management projects that successful demonstration will open a new high-margin revenue stream as a qualified supplier of space-rated propellant systems.
