**Item 5.04 Temporary Suspension of Trading Under Registrant's Employee Benefit Plans**

On October 30, 2025, MFA Financial, Inc. (the "Company") delivered to its directors and executive officers (collectively, the "Covered Persons") a notice (the "Blackout Period Notice") pursuant to Rule 104(b)(2)(i) of Regulation BTR adopted by the Securities and Exchange Commission, which informed the Covered Persons of upcoming restrictions on the trading of the Company's common stock (the "Common Stock") and the Company's 7.50% Series B Cumulative Redeemable Preferred Stock (the "Series B Preferred") due to a planned "blackout period" relating to the MFA Financial, Inc. 401(k) Savings Plan (the "Plan").

The blackout period under the Plan is being imposed in connection with the removal of each of the Common Stock and the Series B Preferred as investment options under the Plan and the liquidation of shares of Common Stock and Series B Preferred held in the Plan at the time of the blackout period. The blackout period will begin at 4:00 p.m. Eastern Time on December 1, 2025, and it is expected to end following the close of business on December 5, 2025.

During the blackout period, participants in the Plan will be unable to execute any transactions involving either the Common Stock or the Series B Preferred in their Plan accounts, including transactions involving exchanges in and/or out of the Common Stock and the Series B Preferred and distributions involving the Common Stock and the Series B Preferred. In addition, during the blackout period, participants in the Plan will be unable to direct or diversify the assets that had been invested in the Common Stock and/or the Series B Preferred at the start of the blackout period.

While the blackout period is in effect, the Covered Persons (and their immediate family members who share their residence) will be prohibited from, directly or indirectly, engaging in any purchase, sale, transfer, acquisition, or disposition of any shares of Common Stock and/or Series B Preferred, including any options or other derivative securities with respect to any of these securities, subject to limited exclusions and exemptions. These restrictions apply whether or not the Covered Person is a participant in, or is eligible to participate in, the Plan. The Company will advise the Covered Persons if the blackout period ends earlier or later than the specified date and time.

Inquiries regarding the blackout period may be directed to Hal Schwartz, Senior Vice President and General Counsel of the Company, by telephone at 212-207-6400 or in writing at c/o MFA Financial, Inc., One Vanderbilt Avenue, 48th Floor, New York, New York 10017.
