Mach Industries Raises Additional $600 Million to Scale Defense Manufacturing

HUNTINGTON BEACH, Calif., Sept. 10, 2026 /PRNewswire/ -- Mach Industries, a defense manufacturer developing advanced autonomous systems for the U.S. military and its allies, today announced a $600 million continuation of its Series C financing, bringing the company's valuation to $3.7 billion. Mach Industries is proud to continue its partnership with Ribbit Capital, Infinite Capital, Bedrock Capital, Sequoia, and others as the company invests in its growth.

This marks a step-up in valuation for Mach Industries and provides additional capital to accelerate the company's next phase. The financing will support continued development of platforms across long-range strike, counter-UAS, and other mission areas, while expanding the manufacturing infrastructure required to produce them at scale. Across weapons platforms, propulsion, energetics, and advanced manufacturing, Mach Industries is building the capabilities required to move its portfolio of defense systems into scaled production.

"Modern deterrence requires an industrial base capable of building relevant capabilities at the speed and volume the mission demands," said Ethan Thornton, Founder and CEO of Mach Industries. "This investment allows us to continue expanding that capacity while moving new platforms from development into production faster."

Mach Industries operates a 115,000-square-foot headquarters and manufacturing facility in Huntington Beach, California, with additional propulsion, energetics, and production infrastructure across the state. The company is building a vertically integrated defense industrial base spanning airframes, jet engines, solid rocket motors, energetic systems, autonomy, and advanced manufacturing.

This financing follows Mach Industries' $300 million Series C and reflects continued progress across the company's portfolio. The company has increased capacity across airframes and propulsion while advancing systems in long-range strike, counter-UAS, and other mission areas. The launch of Mach Energetics further strengthened the company's testing and production capabilities.
