BlackRock TCP Capital Corp. is a business development company that provides debt and equity capital to U.S. middle-market companies, primarily through senior and junior secured loans and other private credit investments. The company operates as a regulated investment company, which means it is structured to pass through most taxable income to shareholders rather than pay corporate-level tax. Its investment activities are managed by an advisor within the BlackRock platform, giving it access to BlackRock’s broader credit, risk management, and institutional infrastructure. In 2024 and 2025, the company also went through major platform changes, including the merger with BlackRock Capital Investment Corporation and the addition of HPS senior personnel to the investment committee after BlackRock acquired HPS Investment Partners.
