ARMOUR RESIDENTIAL REIT Q1 2026 Investor Presentation APRIL 22, 2026 1

CORPORATE PROFILE 2 ARMOUR Residential REIT, Inc. (NYSE: ARR) ARMOUR Residential REIT, Inc. (“ARMOUR”; NYSE: ARR) brings private capital into the mortgage markets to support home ownership for a broad and diverse spectrum of homeowners. We seek to create shareholder value through thoughtful investment and risk management of a leveraged and diversified portfolio of mortgage-backed securities issued or guaranteed by U.S Government-sponsored entities. We rely on the decades of experience of our management team for (i) MBS securities portfolio analysis and selection, (ii) access to equity capital and repurchase financing at potentially attractive rates and terms, and (iii) hedging and liquidity strategies to moderate interest rate and MBS price risk. We prioritize maintaining common share dividends appropriate for the intermediate term rather than focusing on short-term market fluctuations.
