Sunshine Biopharma Inc.

Item 1.01. Entry into a Material Definitive Agreement. On October 8, 2026, Sunshine Biopharma Inc. (the “Company”) entered into a placement agent agreement (the “Placement Agent Agreement”) with Aegis Capital Corp. (the “Placement Agent”), in connection with a best efforts public offering (the “Offering”) of (A) 10,509,082 common units (the “Common Units”), each consisting of (i) one share of the Company’s common stock, par value $0.001 per share (“Common Stock”), and (ii) two Series D warrants (the “Series D Warrants”), each exercisable for one share of Common Stock; and (B) 400,000 pre-funded units (the “Pre-Funded Units”), each consisting of (i) one pre-funded warrant (the “Pre-Funded Warrants”) to purchase one share of Common Stock and (ii) two Series D Warrants. The purchase price of each Common Unit was $0.55, and the purchase price of each Pre-Funded Unit was $0.54999. The Pre-Funded Warrants are immediately exercisable, have an exercise price of $0.00001 and may be exercised at any time until all Pre-Funded Warrants are exercised in full. The Pre-Funded Warrants were exercised in full prior to the closing of the Offering. The Series D Warrants are exercisable immediately upon issuance at an initial exercise price of $0.66 per share (equal to 120% of the public offering price per Common Unit) and will expire five years from the date of issuance.

The Share Combination Event provision will be effective only upon receipt of such stockholder approval as may be required by the applicable rules and regulations of the Nasdaq Capital Market. The Series D Warrants will be subject to no more than one such adjustment upon a Share Combination Event. The Offering closed on October 9, 2026. The gross proceeds to the Company were approximately $6 million, before deducting placement agent fees and other expenses payable by the Company. The Offering was made pursuant to an effective registration statement on Form S-1 (File No. 333-299274) and the preliminary prospectus contained therein, which was filed by the Company with the Securities and Exchange Commission (the “SEC”) on October 2, 2026 and declared effective on October 7, 2026.
