[424B5] MFA Financial, Inc Prospectus Supplement (Debt Securities)
MFA Financial, Inc. is offering up to $100,000,000 of preferred stock through an “at the market” distribution agreement with BTIG and JonesTrading. The offering includes 7.50% Series B cumulative redeemable preferred stock and 6.50% Series C fixed-to-floating rate cumulative redeemable preferred stock, which will be fungible with existing series and carry the same CUSIPs. As of the supplement date there are 8,000,000 Series B and 11,000,000 Series C shares outstanding; last reported NYSE sale prices on August 14, 2025 were $21.67 (Series B) and $24.44 (Series C).
The company reported total assets of approximately $11.7 billion at June 30, 2025 with about $8.8 billion (76%) in residential whole loans and approximately $1.8 billion (16%) in securities. Proceeds will fund general corporate purposes, including additional mortgage-related investments, share repurchases and potential debt repayment. The Series C dividend is linked to Three-Month CME Term SOFR plus spreads; neither series has a credit rating. The preferred stock ranks junior to indebtedness; at June 30, 2025 approximately $9.9 billion of liabilities ranked senior to the preferred stock.
- Access to capital: Up to $100,000,000 available via an ATM program provides flexible funding for growth, buybacks or debt repayment.
- Market integration: Offered shares are fungible with existing Series B and Series C and are listed on the NYSE, aiding liquidity and secondary market trading.
- Different income options: Investors can choose fixed-rate income (7.50% Series B) or SOFR-linked floating income (6.50% Series C) aligned with interest-rate views.
- Subordination risk: Both preferred series are junior to approximately $9.9 billion of existing indebtedness, reducing recovery priority in distress scenarios.
- No credit rating: Neither Series B nor Series C has been rated, which may reduce market demand or increase volatility for these securities.
- SOFR exposure: Series C dividends reference Three-month CME Term SOFR plus spreads; SOFR has a limited history and may be volatile or subject to methodology changes.
- Potential dilution and issuance authority: Board can issue additional preferred or senior securities that could dilute holders and affect dividend or redemption prospects.
- Ownership limits: Charter’s 9.8% ownership restriction to preserve REIT status may limit convertible holders’ ability to receive or hold common stock upon conversion.
Insights
TL;DR: This ATM preferred offering raises flexible capital but increases claims junior to substantial existing debt.
The offering provides MFA with up to $100 million of incremental capital that can be deployed for mortgage assets, share repurchases or debt reduction, which supports liquidity and balance sheet flexibility. The Series B carries a fixed 7.50% coupon and the Series C uses a SOFR-linked floating rate, giving investors differing income profiles. The shares are listed on the NYSE and will be fungible with existing series, easing market integration. However, the preferred stock is unrated and ranks junior to about $9.9 billion of existing liabilities, which is material relative to the capital structure and relevant to recovery in downside scenarios.
TL;DR: Charter provisions and ownership limits protect REIT status but may restrict investor flexibility and conversion mechanics.
MFA’s charter retains broad board authority to issue additional preferred or senior securities and includes a 9.8% ownership limit designed to preserve REIT qualification; these features can dilute voting influence and limit conversions into common stock. Change-of-control conversion caps (the Share Caps) and redemption rights may constrain holders’ ability to realize full liquidation preference in certain scenarios. Limited voting rights for preferred holders are standard but notable in the context of potential dividend arrearages triggering director elections. These governance elements materially affect investor remedies and control dynamics.
