Item 5.02.   Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On April 30, 2026, at the 2026 annual meeting of stockholders (the “Annual Meeting”) of ARMOUR Residential REIT, Inc. (“ARMOUR”), ARMOUR’s stockholders approved ARMOUR’s Fourth Amended and Restated 2009 Stock Incentive Plan (the “Fourth A&R Plan”), which provides for the granting of common stock, par value $0.001 per share (“Common Stock”) of ARMOUR, restricted shares of Common Stock, stock options, performance shares, performance units, restricted stock units, stock appreciation rights and other equity-based and cash-based awards to directors, officers and other employees and other persons who provide services to ARMOUR (each an “Eligible Individual”). Prior to the approval by the stockholders of the Fourth A&R Plan, ARMOUR’s existing Third Amended and Restated Stock Incentive Plan (the “Plan”) provided for the grant of up to 800,000 shares of Common Stock. The Fourth A&R Plan increases by 1,000,000 the number of shares of Common Stock authorized for issuance under the Plan. As of March 19, 2026, there were 3,506 shares that remained available for grant under the Plan. The Fourth A&R Plan also amends the Plan as follows: it (i) proportionally lowers the maximum number of shares of Common Stock that may be subject to grants of certain awards to any one Eligible Individual in any fiscal year from 750,000 to 150,000 to reflect the one-for-five reverse stock split of ARMOUR’s Common Stock effected in September 2023, in accordance with the terms of the Plan, (ii) sets the effective date of the Fourth A&R Plan as April 30, 2026, the date of the Annual Meeting, (iii) establishes a ten year term such that the Fourth A&R Plan will terminate on the day immediately preceding the tenth anniversary of the Effective Date, or April 29, 2036, (iv) adds a clawback provision to clarify that any award granted under the Fourth A&R Plan may also provide for the cancellation or forfeiture of such award and repayment to ARMOUR of any shares of common stock issued under and/or any other benefit related to an award, consistent with the terms of ARMOUR’s Clawback Policy, (v) eliminates outdated Internal Revenue Code Section 162(m) provisions and (vi) reflects certain non-material updates. Other than as described above, the Plan has not been materially changed from its state immediately prior to the Annual Meeting.

The Fourth A&R Plan is described in more detail in Proposal 5 in ARMOUR’s definitive proxy statement on Schedule 14A filed with the Securities and Exchange Commission on March 19, 2026 (the “Proxy Statement”). The descriptions of the Fourth A&R Plan contained herein and in the Proxy Statement do not purport to be complete and are qualified in their entirety by reference to the full text of the Fourth A&R Plan, a copy of which was filed as Appendix A to the Proxy Statement and is incorporated herein by reference.
