This prospectus supplement updates and supplements the information contained in the prospectus dated December 15, 2025 (as may be supplemented or amended from time to time, the "Prospectus"), which forms part of our registration statement on Form S-1 (File No. 333-291262), as amended, with the information contained in our Current Report on Form 8-K which was filed with the Securities and Exchange Commission on December 23, 2025 (the "Current Report").

The Prospectus and this prospectus supplement relate to the resale, from time to time, which may be offered by Keystone Capital Partners, LLC ("Keystone", "Keystone Capital Partners" or the "Selling Stockholder"), or their pledgees, donees, transferees, or other successors in interest, of up to 2,506,893,959 shares of common stock, par value $0.0001 per share (the "Common Stock"), of SRx Health Solutions, Inc., a Delaware corporation ("we," "our," the "Company"). The shares of Common Stock being offered by the Selling Stockholder are outstanding or issuable pursuant to the Common Share Purchase Agreement dated July 7, 2025 by and among the Company and the Selling Stockholder, as amended on October 28, 2025 (the "ELOC Purchase Agreement"). See "The Keystone Capital Transaction" for a description of the Purchase Agreement. We may elect, in our sole discretion, to issue and sell such 2,506,893,959 shares of Common Stock (the "Keystone Purchase Shares") to Keystone, from time to time from and after the Keystone Commencement Date (as defined below) under the ELOC Purchase Agreement. Please refer to "Selling Stockholder" beginning on page 70. Such registration does not mean that Keystone will actually offer or sell any of these shares of Common Stock. We will not receive any proceeds from the sales of the above shares of Common Stock by the Selling Stockholder; however, we will receive proceeds under the Purchase Agreement if we sell shares of Common Stock to the Selling Stockholder.
