Acorn Capital Management

Acorn Capital Management

Acorn Capital Management invests from Oklahoma City, with additional offices in Washington, D.C. and Watford, UK. The firm focuses exclusively on middle-market companies that support aerospace, defense, intelligence, and space programs, a posture reinforced across more than two decades of operations. Its portfolio spans aviation services, specialty parts distribution, defense electronics, and technical asset services. Confirmed holdings include Berry Aviation, a Department of Defense CARB-approved air carrier with a fleet exceeding 25 aircraft; TSS Solutions, which upgrades and repairs ground-based radar and SATCOM systems for the U.S. and allied militaries; and EirTrade Aviation, acquired in 2023, an engine and airframe end-of-life services provider with operations in Ireland and Dallas, Texas. Other named portfolio companies — Pan Am Flight Academy, Raisbeck, DIMO, Robbins-Gioia, and Sentry Aerospares — fill adjacent positions in commercial aviation training, aircraft performance modification, and mission-critical parts supply. The firm operates through sequential funds, with current vehicles labeled Fund IV and Fund V on its website. The firm's website indicates a multi-fund structure with portfolio companies assigned to Fund IV and Fund V. In 2023, Acorn acquired EirTrade Aviation to expand its technical asset servicing and parts-trading capability across Europe and the United States. Beyond its Oklahoma City headquarters, the firm maintains a presence near federal procurement and intelligence hubs through its Washington, D.C. office and supports transatlantic logistics from Watford, UK. No separate philanthropic foundation, co-investor club membership, or adjacent operating business is disclosed in available public materials. Acorn occupies a structurally distinct position by concentrating entirely on the defense-industrial middle market. The firm does not diversify into consumer, software, or healthcare verticals common among generalist private equity managers. Its proximity to U.S. government contracting apparatus — physically and strategically — allows it to source, diligence, and manage companies whose revenue is anchored in long-cycle defense procurement and sustainment programs.
