About ARMOUR Residential REIT, Inc.
ARMOUR Residential REIT is a mortgage real estate investment trust based in Vero Beach, Florida. It doesn't own property: it borrows heavily to buy residential mortgage-backed securities (mostly ones guaranteed by Fannie Mae, Freddie Mac or Ginnie Mae). It's known for paying a very high monthly dividend, recently $0.24 a share, which works out to a yield of roughly 20%+. The company is externally managed, so it has very few employees of its own.
How it makes money
ARMOUR earns interest on its mortgage-backed securities, which are funded mostly with short-term repurchase (repo) borrowing. Its profit comes largely from the gap between the interest it earns and its borrowing costs, adjusted for interest-rate hedges such as swaps. It's highly leveraged, with debt at roughly 7–8 times equity. That means swings in bond prices can sharply change its book value. In Q3 2026, for example, it reported a GAAP net loss of about $327 million and book value per share fell about 17% as mortgage spreads widened and Treasury yields rose. As a REIT, it must pay out most of its taxable income as dividends.
