On February 23, 2026, NRx Pharmaceuticals, Inc. (the "Company") filed its definitive proxy statement for its annual meeting of stockholders to be held on March 23, 2026 (the "Proxy Statement") with the Securities and Exchange Commission. The Company is providing this supplement (this "Supplement") solely to correct an error in the form of proxy included with the Proxy Statement that was filed (the "Proxy Card") and the cover letter to the Proxy Statement from the Chairman of the Board of Directors (the "Cover Letter"). The Proxy Card and the Cover Letter mailed to stockholders was corrected prior to the mailing.

Proposal 2 on the Proxy Card and the Cover Letter, which provides the Company's stockholders a vote, on a non-binding, advisory basis, on the compensation of the Company's named executive officers has been corrected to be numbered as Proposal 4; Proposal 3 on the Proxy Card and the Cover Letter, which provides the Company's stockholders a vote to approve an amendment to the NRx Pharmaceuticals, Inc. 2021 Omnibus Incentive Plan has been corrected to be numbered as Proposal 2; and Proposal 4 on the Proxy Card and the Cover Letter, which provides the Company's stockholders a vote to ratify the selection of Weinberg & Company, P.A. as the Company's independent auditors for the fiscal year ending December 31, 2025 has been corrected to be numbered as Proposal 3.

The corrected Proxy Card and Cover Letter are presented on the following pages of this Supplement. The Proxy Statement itself and the link for voting by internet each contain reference to the correct Proxy Card and the Cover Letter. All other information contained in the Proxy Statement and Proxy Card is correct and no other changes have been made to the Proxy Statement or the Proxy Card.

This Supplement should be read in conjunction with the Proxy Statement, and other than the revisions described above, this Supplement does not modify or supersede any information in the Proxy Statement. From and after the date of this Supplement, any references to the "Proxy Statement" are to the Proxy Statement as supplemented hereby. If you have already voted, you do not need to vote again unless you would like to change or revoke your prior vote on any proposal. If you would like to change or revoke your prior vote on any proposal, please refer to the section titled "May I revoke my proxy?" in the Proxy Statement for specific instructions on how to do so.
