MidCap Financial Investment Corporation is a closed-end, externally managed Business Development Company and regulated investment company that originates and invests in directly negotiated first lien senior secured loans to privately held U.S. middle-market companies, typically with less than $75 million in EBITDA, and to a lesser extent in subordinated debt, mezzanine loans, and equity interests in middle-market firms. The company generates current income and long-term capital appreciation through its diversified portfolio of primarily floating-rate, below-investment-grade debt instruments that are typically illiquid and difficult to value. MidCap Financial is advised and managed by Apollo Investment Management, an affiliate of Apollo Global Management, and operates under the regulatory framework of a Business Development Company subject to the Investment Company Act of 1940.
