ARMOUR Residential REIT Inc (NYSE: ARR) is a mortgage real estate investment trust that invests in residential mortgage-backed securities. It makes money by earning the spread between interest income on its leveraged MBS portfolio and the cost of short-term repurchase financing used to fund those holdings. ARMOUR deploys private capital into U.S. mortgage markets by holding a diversified portfolio of MBS, using hedging strategies to moderate interest rate and MBS price risk. The company prioritizes maintaining common share dividends suited to intermediate-term sustainability rather than short-term optimization. Management responsibilities, including MBS portfolio analysis, equity capital access, repurchase financing, and hedging, are handled by an experienced external-style team relying on decades of mortgage market experience. ARMOUR completed a one-for-five reverse stock split effective September 29, 2023. The 10-K for the fiscal year ended was filed February 18, 2026 (accession 0001428205-26-000029).
