**Item 1.01&nbsp;&nbsp;&nbsp;&nbsp;Entry into a Material Definitive Agreement.**

On January 28, 2026, ARMOUR Residential REIT, Inc. ("ARMOUR" or the "Company") entered into Amendment No. 7 (the "Seventh Sales Agreement Amendment"), pursuant to which ARMOUR increased by 15,000,000 the number of shares of common stock, par value $0.001 per share ("Common Stock"), that may be offered and sold under the Company's Equity Sales Agreement, dated July 26, 2023 (the "Sales Agreement"), with BUCKLER Securities LLC, an affiliate of the Company ("BUCKLER"), B. Riley Securities, Inc. ("B. Riley Securities"), Citizens JMP Securities LLC ("Citizens Capital Markets"), JonesTrading Institutional Services LLC ("Jones") and Ladenburg Thalmann & Co. Inc. ("Ladenburg Thalmann"), as sales agents, and the Company's external manager, ARMOUR Capital Management LP, as amended by Amendment No. 1, dated October 25, 2023 (the "First Sales Agreement Amendment"), pursuant to which the Company added StockBlock Securities LLC ("StockBlock") to the Sales Agreement, as further amended by Amendment No. 2, dated June 20, 2024 (the "Second Sales Agreement Amendment"), pursuant to which the Company added BTIG, LLC ("BTIG") to the Sales Agreement, as further amended by Amendment No. 3, dated August 23, 2024 (the "Third Sales Agreement Amendment"), pursuant to which the number of shares of our common stock that may be offered and sold under the Sales Agreement was increased by 25,000,000, as further amended by Amendment No. 4, dated September 20, 2024 (the "Fourth Sales Agreement Amendment"), pursuant to which the Company added Janney Montgomery Scott LLC, as further amended by Amendment No. 5, dated February 13, 2025 (the "Fifth Sales Agreement Amendment"), pursuant to which the number of shares of our common stock that may be offered and sold under the Sales Agreement was increased by 15,000,000, as further amended by Amendment No. 6, dated July 25, 2026 (the "Sixth Sales Agreement Amendment"), pursuant to which the number of shares of our common stock that may be offered and sold under the Sales Agreement was increased by 9,500,000 (as so amended, the "Amended Sales Agreement"). The purpose of the Seventh Sales Agreement Amendment was to (i) increase the number of shares of Common Stock available under the Sales Agreement by 15,000,000 and (ii) remove Janney as a sales agent and add Huntington Securities, Inc. ("Huntington" and together with BUCKLER, B. Riley Securities, BTIG, Citizens Capital Markets, Jones, Ladenburg Thalmann and StockBlock, the "Agents"), as a sales agent. Pursuant to the Amended Sales Agreement, the Company may, from time to time, issue and sell up to 23,244,198 shares (the "Shares") of the Company's Common Stock through or to the Agents. The Amended Sales Agreement includes the offer of 8,244,198 Shares that remained unsold under the Sales Agreement, as amended by the First Sales Agreement Amendment, the Second Sales Agreement Amendment, the Third Sales Agreement Amendment, the Fourth Sales Agreement Amendment, the Fifth Sales Agreement Amendment and the Sixth Sales Agreement, in addition to the offer of an additional 15,000,000 Shares.

The Amended Sales Agreement relates to an "at the market offering" program (the "Offering") and the shares of Common Stock to be sold in the Offering will be issued pursuant to a prospectus supplement (the "ATM Prospectus Supplement") filed with the Securities and Exchange Commission (the "SEC") on January 28, 2026, in connection with the Company's effective shelf registration statement on Form S-3 (Registration No. 333-278327). ARMOUR originally established the equity sales program on July 26, 2023 when it entered into the Sales Agreement, and filed a related prospectus supplement. ARMOUR entered into the First Sales Agreement Amendment on October 25, 2023 and filed a related prospectus supplement. ARMOUR entered into the Second Sales Agreement Amendment on June 20, 2024 and filed a related prospectus supplement. ARMOUR entered into the Third Sales Agreement Amendment on August 23, 2024 and filed a related prospectus supplement. ARMOUR entered into the Fourth Sales Agreement Amendment on September 20, 2024 and filed a related prospectus supplement. ARMOUR entered into the Fifth Sales Agreement Amendment on February 13, 2025 and filed a related prospectus supplement. ARMOUR entered into the Sixth Sales Agreement Amendment on July 25, 2025 and filed a related prospectus supplement. The ATM Prospectus Supplement amends and restates in its entirety such related prospectus supplement and the Common Stock to which the ATM Prospectus Supplement relates is offered pursuant to the terms of the Amended Sales Agreement.

The Seventh Sales Agreement Amendment is filed as Exhibit 1.1 to this Current Report on Form 8-K and is incorporated herein by reference. The foregoing description of the Seventh Sales Agreement Amendment and the transactions contemplated thereby is qualified in its entirety by reference to Exhibit 1.1.

The Company is also filing this Current Report on Form 8-K to provide a legal opinion regarding the validity of the Shares to be issued and sold in the Offering, which opinion is attached hereto as Exhibit 5.1, and is incorporated herein by reference.

This Current Report on Form 8-K shall not constitute an offer to sell or a solicitation of an offer to buy any securities, nor shall there be any sale of these securities in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or other jurisdiction.

Re: Shelf Registration Statement on Form S-3 (Registration No. 333-278327)

Ladies and Gentlemen:

Reference is made to the Registration Statement on Form S-3 (Registration No. 333-278327) (the "Registration Statement") filed with the Securities and Exchange Commission (the "Commission") on March 28, 2024 by ARMOUR Residential REIT, Inc. (the "Company") pursuant to the requirements of the Securities Act of 1933, as amended (the "Act"). We are rendering this opinion letter in connection with the filing of a prospectus supplement dated January 28, 2026 (the "Prospectus Supplement"). The Prospectus Supplement relates to the offering by the Company of up to 23,244,198 shares (the "Shares") of the Company's common stock, par value $0.001 per share (the "Common Stock"), in an "at-the-market" offering, pursuant to an Equity Sales Agreement dated July 26, 2023, as amended by Amendment No. 1 dated October 25, 2023, as further amended by Amendment No. 2 dated June 20, 2024, as further amended by Amendment No. 3 dated August 23, 2024, as further amended by Amendment No. 4 dated September 20, 2024, as further amended by Amendment No. 5, dated February 13, 2025, as further amended by Amendment No. 6, dated July 25, 2025, as further amended by Amendment No. 7, dated January 28, 2026, which Shares are covered by the Registration Statement. We understand that the Shares are to be offered and sold in the manner set forth in the Registration Statement and the Prospectus Supplement.

We have acted as your counsel in connection with the preparation of the Prospectus Supplement. We are familiar with the proceedings taken by the Board of Directors of the Company in connection with the authorization, issuance and sale of the Shares. We have examined all such documents as we have considered necessary in order to enable us to render this opinion letter, including, but not limited to, (i) the Registration Statement, (ii) the Base Prospectus, dated March 28, 2024, included with the Registration Statement (the "Prospectus"), (iii) the Prospectus Supplement, (iv) the Company's Articles of Incorporation, as amended, (v) the Company's Bylaws, as amended, (vi) certain resolutions adopted by the Board of Directors of the Company, the independent members of the Board of Directors of the Company and the Audit Committee of the Board of Directors of the Company, (vii) corporate records and instruments, (viii) a specimen certificate representing the Shares, and (ix) such laws and regulations as we have deemed necessary for the purposes of rendering the opinion set forth herein.
