**EXPLANATORY NOTE**

MFA Financial, Inc. (the "Company," "we" or "our") is filing this post-effective amendment to deregister the shares of 7.50% Series B Cumulative Redeemable Preferred Stock, par value $0.01 per share ("Series B Preferred Stock"), of the Company, previously registered under the Company's registration statement on Form S-8 No. 333-272960 (the "Registration Statement"), which registered the offering of 40,000 shares of Series B Preferred Stock and an indeterminate number of interests pursuant to the Company's 401(k) Savings Plan (the "Plan").

Effective after 4:00 p.m. Eastern Time on December 1, 2025, investing in our Series B Preferred Stock ceased to be an investment option under the Plan, and from and after such time and date through December 5, 2025, all balances invested in our Series B Preferred Stock and related plan interests were liquidated. Accordingly, no offers or sales of shares of Series B Preferred Stock under the Plan or any related plan interests related thereto are required to be registered under the Registration Statement. The Company hereby terminates the effectiveness of the Registration Statement, and the Registrant hereby deregisters all shares of the Series B Preferred Stock and all related plan interests registered pursuant to the Registration Statement that remain unsold or unissued as of the date hereof. The Registration Statement is hereby amended, as appropriate, to reflect the deregistration of such Series B Preferred Stock and related plan interests.
