Acorn Capital Management

Acorn invests solely in middle-market companies supporting aerospace, defense, intelligence, and space programs. The firm's current portfolio covers aviation services, defense electronics, specialty parts distribution, technical asset management, and commercial flight training. There is no evidence of diversification into other industries.

Acorn operates through sequential private equity funds, currently labeled Fund IV and Fund V on its website. Portfolio companies are assigned to a specific fund — for example, Berry Aviation, DIMO, Raisbeck, Robbins-Gioia, and Sentry Aerospares sit in Fund IV, while EirTrade Aviation and Pan Am Flight Academy are held in Fund V. The firm's website does not publish total assets under management or individual fund sizes.

Acorn is headquartered in Oklahoma City with an additional office in Washington, D.C. and a UK office in Watford, Hertfordshire. Portfolio companies operate across the contiguous United States and internationally — Berry Aviation has conducted OCONUS operations including Hawaii, Afghanistan, Peru, and Africa, while EirTrade Aviation maintains facilities in Ireland and Dallas, Texas.

Acorn's own portfolio page describes the firm as a private equity investor that acquires companies outright; every listed portfolio company is a platform-level operating business, not a fund commitment. The firm does not disclose making LP commitments to external managers or running a fund-of-funds program.

Acorn does not publicly disclose the names or titles of its principals on its website or in available public filings. No investment committee, managing partner, or founder is identified in the firm's owned media or the Altss research record. This non-disclosure distinguishes Acorn from peers who routinely publish team pages.
