Lone Star Investment Advisors

J. Patrick McDowell serves as President & Managing Partner and leads the firm's investment activities. His background includes a prior partnership at SCF Partners, a Houston-based energy-focused investment firm, where he contributed to deal origination and management in the energy services and industrial sectors. Day-to-day deal execution is led by the managing partner with support from the investment team, though the firm does not publicly list additional senior investment professionals.

The firm targets lower-mid-market companies across manufacturing, industrial distribution, and energy services. Enterprise values generally fall below $100 million. Transactions include control buyouts, recapitalizations, and corporate divestitures from larger industrial companies. The firm focuses on North American businesses, particularly those operating in the Texas-Oklahoma-Louisiana energy and industrial corridor.

No. Lone Star Investment Advisors is a Dallas-based lower-mid-market private equity firm founded by J. Patrick McDowell. Lone Star Funds is an entirely separate global private equity firm headquartered in Dallas, founded by John Grayken. The two firms share a city and a name but have no known affiliation, common ownership, or shared investment activity.

The firm's deal sourcing network is rooted in the energy services and industrial sectors across the Sunbelt. J. Patrick McDowell's SCF Partners background provides an operational and relationship footprint in energy-adjacent industrial businesses in Texas and surrounding states. The firm also targets corporate divestitures from larger industrial conglomerates, which serves as a distinct origination channel alongside traditional intermediary-driven deal flow.

Lone Star Investment Advisors does not publicly disclose assets under management, fund sizes, or investment performance. The firm has not registered any publicly reported fund closes with the SEC in a manner that would make such figures accessible in the public record. AUM data remains entirely undisclosed, consistent with the posture of a privately held lower-mid-market manager.
