Mach Industries acquires Exquadrum for $50 million

Defense startup Mach Industries has acquired Exquadrum, a developer of solid rocket motors (SRMs)—a critical propulsion component—in a cash-and-equity deal valued at $50 million. Following the transaction, Exquadrum has been rebranded as Mach Energetics and fully integrated into Mach’s operations. The acquisition brings Exquadrum’s 85 employees and its 70,000-square-foot facility in Victorville, California, under Mach’s control. The two companies first connected last September at an MIT recruiting event, and Mach reportedly beat out upward of eight other potential buyers to secure the deal roughly five months later.

The acquisition targets a critical bottleneck in the domestic defense industrial base. The domestic solid rocket motor market is effectively controlled by just two large primes (large defense contractors): Aerojet Rocketdyne and Northrop Grumman. This concentration has left the supply chain highly constrained, with lead times stretching for years. To address these shortages, the Pentagon has begun funding alternative suppliers, including awarding $43.7 million to defense tech firm Anduril in February to expand its solid rocket motor production capacity.

Mach plans to use the acquisition to transition from a pure systems builder into a component supplier for the broader defense ecosystem. Mach Energetics plans to sell components, testing services, and subsystems to other defense firms. Ethan Thornton, the founder and CEO of Mach Industries, framed the supply chain consolidation as an operational necessity.

“As we deliver vehicles to the warfighter, we’ll continue to vertically integrate our supply chain across solid rocket motors, engines, radar, and avionics to ensure we deliver the best possible product at the lowest cost. In many areas of the defense industrial base, these components are not only too expensive or lacking performance, they’re simply unavailable, with lead times stretching years. In short, vertical integration is non-optional,” Thornton said.

With the integration of Exquadrum’s team, the combined company now employs roughly 350 people. Exquadrum co-founders Kevin Mahaffy and Eric Schmidt are taking on leadership roles within Mach Energetics and the broader organization. The acquisition comes as Mach prepares to scale production, with five vehicle programs currently in development and plans to enter production on at least three of them this year.

The company’s financial position includes:

• Total funding raised: Nearly $200 million
• Most recent round: A $100 million Series B funding round closed last June
• Lead investors: Bedrock Capital, Khosla Ventures, and Sequoia Capital
• Current valuation: $470 million

Why it matters

This acquisition signals a strategic shift for Mach Industries from a systems builder to a critical infrastructure supplier, highlighting the intense pressure on defense startups to vertically integrate in a market defined by supply chain constraints.
