MFA Financial Inc (NYSE: MFA) is a real estate finance company that invests in residential mortgage assets, primarily residential whole loans and mortgage-backed securities. It earns income on the spread between the yield on its mortgage assets and the cost of borrowing used to finance those assets. The residential whole loan portfolio includes loans on one-to-four family properties that do not meet the definition of a Qualified Mortgage, as well as other residential loan types disclosed in the FY2025 10-K filed February 20, 2026. MFA operates as a real estate investment trust (REIT), which requires it to distribute the majority of taxable income to shareholders. The portfolio is organized into segments reported in Note 15 of the FY2025 consolidated financial statements. Capital structure is debt-heavy by design, as leverage is the primary mechanism for generating returns on mortgage spread.
