Armour Residential REIT, Inc. Annual Report Summary

This summary distills the key financial performance, strategic actions, and risks for Armour Residential REIT, Inc. for the fiscal year ended December 31, 2025, including important developments in early 2026. We aim to provide retail investors with a clear and comprehensive understanding of the company's operations.

Business Overview

Armour Residential REIT, Inc. (ARR) operates as a mortgage real estate investment trust (mREIT). It primarily invests in Agency Mortgage-Backed Securities (MBS) and U.S. Treasury Securities. Agency MBS are debt instruments backed by residential mortgages and guaranteed by U.S. government-sponsored enterprises like Fannie Mae and Freddie Mac, making them relatively low-credit-risk investments. U.S. Treasury Securities are direct obligations of the U.S. government, considered among the safest investments available. ARR's core strategy is to generate income from the net interest margin—the difference between the interest it earns on its portfolio assets and the cost of its borrowings.

To manage the inherent interest rate risks of its portfolio, ARR actively uses financial derivatives such as interest rate swaps and Eurodollar futures. These instruments act as hedges, aiming to lessen the impact of adverse interest rate movements on its asset values and borrowing costs.

Financial Performance

For the fiscal year 2025, Armour Residential REIT reported a net income of approximately $75 million. This marks a decrease from $110 million in 2024 but an improvement from a net loss of $25 million in 2023. Earnings Per Share (EPS) stood at $0.85 for 2025, down from $1.20 in 2024. The challenging interest rate environment and increased funding costs primarily drove the decline in net income, leading to a narrowing of the net interest margin. Effective hedging strategies partially offset this compression.

Total revenue for 2025 reached an estimated $280 million, compared to $350 million in 2024 and $200 million in 2023. The company maintained a consistent dividend payout of $0.10 per common share per month throughout 2025, demonstrating its commitment to shareholder returns. As of December 31, 2025, the Book Value Per Share (BVPS) was approximately $9.50, a slight decrease from $10.20 at the end of 2024, mainly due to mark-to-market adjustments on its investment portfolio.

Risk Factors

Investors should be aware of the following principal risks:

• Interest Rate Risk: As an mREIT, ARR is highly sensitive to interest rate changes. Rising rates can increase borrowing costs, decrease the value of existing MBS, and potentially lead to spread compression (a narrowing of the net interest margin). While ARR employs hedging strategies, they may not fully mitigate these risks.
• Counterparty Concentration Risk: A substantial portion of ARR's repurchase agreements and derivative contracts are concentrated with a limited number of financial institutions, including BUCKLER Securities LLC. The financial distress or default of a major counterparty could severely impact ARR's liquidity and financial position.
• Fair Value Fluctuations: The fair value of ARR's investment portfolio, particularly its Agency MBS, is subject to market volatility. Changes in interest rates, credit spreads, and market liquidity can lead to significant unrealized gains or losses, affecting the company's book value and profitability. Valuing these assets relies on various inputs, including Level 2 (observable market data) and Level 3 (unobservable inputs) fair value measurements, which carry inherent estimation risk.
• Prepayment Risk: When interest rates decline, mortgage holders may refinance their loans, leading to earlier-than-expected principal payments on MBS. This prepayment risk can force ARR to reinvest capital at lower yields, negatively impacting its net interest income.
• Leverage Risk: The company's high leverage ratio amplifies both potential gains and losses. Adverse market movements can rapidly erode equity and trigger margin calls on its repurchase agreements.

Management Discussion (MD&A Highlights)

Management highlighted the challenging interest rate environment in 2025. This environment led to a narrowing of the net interest margin and a decrease in net income compared to the prior year, despite effective hedging strategies. To manage capital and enhance shareholder value, ARR continued its common stock repurchase program, buying back approximately 5 million shares. The company also used "At-the-Market" (ATM) sales agreements, which allow for flexible capital raising, to generate an estimated $50 million through common stock and $30 million through preferred stock. These funds provided flexible financing for portfolio management and general corporate purposes. Management demonstrated alignment with shareholders by waiving approximately $5 million in management fees, which boosted profitability.

ARR managed its liquidity and capital resources through cash on hand, secured repurchase agreements, and capital raises. The company's highly leveraged investment strategy, with a leverage ratio of approximately 8.5x, is typical for mREITs and is actively managed through its hedging program. The ongoing relationship with BUCKLER Securities LLC, which handles a significant portion of borrowing and investment transactions, forms a key component of ARR's operational and financial structure. Management's strategic focus remains on dynamic portfolio adjustments and risk mitigation to navigate market volatility and optimize returns.

Financial Health

As of December 31, 2025, Armour reported total assets of approximately $12.5 billion and total debt of $11.0 billion. The company held a cash and cash equivalents balance of $150 million, providing immediate liquidity.

ARR primarily finances its investments through repurchase agreements. These are a common form of secured short-term borrowing in the mREIT sector, where the company sells securities and agrees to repurchase them later at a slightly higher price. The company's capital structure includes both common stock and Series C Preferred Stock, offering investors different risk-return profiles. The leverage ratio (total debt to equity) stood at approximately 8.5x at year-end 2025, indicating a highly leveraged investment strategy typical for mREITs.

A significant aspect of ARR's financial structure involves its relationship with BUCKLER Securities LLC, a related party. BUCKLER Securities LLC acts as a counterparty for certain borrowing activities and investment transactions in Agency and U.S. Treasury securities. In 2025, transactions with BUCKLER represented approximately 15% of total repurchase agreements and 10% of total investment purchases, highlighting a concentrated and integral relationship that warrants investor attention.

Future Outlook

Armour's management and Board of Directors receive incentives through a 2009 Stock Incentive Plan, which includes Restricted Stock Units (RSUs), aligning their interests with long-term shareholder value. The consistent and significant dealings with BUCKLER Securities LLC suggest a stable operational and advisory framework.

Looking ahead, Armour Residential REIT anticipates continued volatility in the interest rate environment, influenced by global economic conditions and central bank monetary policies. The company's strategy for 2026 and beyond focuses on:

• Dynamic portfolio management: Actively adjusting its MBS portfolio and hedging strategies to optimize net interest margin as market conditions evolve.
• Prudent capital allocation: Balancing share repurchases, dividend distributions, and new capital raises (via ATM programs) to maintain financial flexibility and enhance shareholder returns.
• Risk management: Continuously monitoring and adapting its hedging instruments to mitigate interest rate and prepayment risks.

Subsequent events in early 2026 show the company actively managing its portfolio. In January and February 2026, it completed approximately $500 million in MBS sales and $400 million in new MBS purchases, reflecting ongoing portfolio rebalancing efforts. The company remains sensitive to potential regulatory changes affecting the housing finance market and the broader financial sector, which could impact its operating environment.

Competitive Position

The mREIT sector is highly competitive, with numerous companies vying for investment opportunities in Agency MBS and other mortgage-related assets. Competition primarily centers on access to capital, management expertise in portfolio construction and risk management, and the ability to efficiently execute trades and hedging strategies. Barriers to entry are relatively low, as the business primarily involves financial transactions rather than physical assets. ARR competes by leveraging its management team's experience, its established relationships with counterparties for financing and derivatives, and its disciplined approach to risk management. The company's ability to effectively manage its cost of funds and optimize its net interest margin in varying interest rate environments is crucial for maintaining its competitive standing.
