Annaly Capital Management Inc. is one of the largest mortgage real estate investment trusts (mREITs) in the United States, operating as a diversified capital manager in the housing finance sector. The company's business model centers on generating income through the net interest margin—the spread between the interest earned on its long-term mortgage assets and its short-term borrowing costs.
Annaly operates across three core investment segments: Agency, Residential Credit, and Mortgage Servicing Rights (MSR). The Agency segment is the largest, comprising the vast majority of its portfolio, and focuses on agency mortgage-backed securities (MBS) collateralized by residential mortgages and guaranteed by entities such as Fannie Mae, Freddie Mac, and Ginnie Mae. The Residential Credit segment invests in non-agency residential whole loans and securitized products, offering higher yields with elevated credit risk. The MSR segment provides recurring fee-based revenue that often acts as a natural hedge against MBS valuation fluctuations, as servicing values typically rise when interest rates increase.
By utilizing sophisticated hedging and leverage strategies, Annaly manages interest rate and prepayment risks inherent in the mortgage market. The company relies on short-term repurchase agreements (repo financing) to fund its asset purchases. As a REIT, Annaly is exempt from federal income tax provided it distributes at least 90% of its taxable income to shareholders, making it a prominent vehicle for yield-seeking investors. The firm operates primarily in the United States and maintains a significant scale advantage that allows for operational efficiencies and competitive funding costs.
