ARMOUR RESIDENTIAL REIT, INC.

Monthly Update FEBRUARY 2024

ARMOUR Residential REIT, Inc. (“ARMOUR”; NYSE ticker ARR) brings private capital into the mortgage markets to support home ownership for a broad and diverse spectrum of Americans. 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 on 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.

ARMOUR is externally managed by ARMOUR Capital Management LP, who is also the majority owner of BUCKLER Securities LLC, a FINRA registered broker-dealer that is the largest provider of ARMOUR’s repurchase financing.
