Item 1.01 Entry into a Material Definitive Agreement.

On July 6, 2026, Tarsus Pharmaceuticals, Inc. (the “Company”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with iRenix Medical, Inc., a Delaware corporation (“iRenix”), Dolores Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of the Company (“Merger Sub”) and Fortis Advisors LLC, as the securityholders’ representative (the “Securityholders’ Representative”). Pursuant to the Merger Agreement, on July 6, 2026, Merger Sub merged with and into iRenix (the “Merger”), with iRenix surviving the Merger as a wholly-owned subsidiary of the Company. The aggregate up-front consideration (the “Up-front Consideration”) paid by the Company for the transactions contemplated by the Merger Agreement (the “Acquisition”) was (i) an amount in cash equal to $37,500,000, subject to customary adjustments and a post-closing purchase price adjustment, and (ii) 607,093 shares of common stock, par value $0.0001 per share, of the Company. In addition to the Up-front Consideration, the equityholders of iRenix will be entitled to receive: (i) milestone payments up to an aggregate amount equal to $490,000,000 in the event certain regulatory approval and/or commercial sales milestones are achieved and (ii) revenue sharing payments in the low-to-mid single digits of future net sales of certain products.

In connection with the Merger Agreement, the Company and the Securityholders’ Representative entered into an escrow agreement pursuant to which the Company has deposited certain funds for purposes of securing the indemnification obligations of the former securityholders of iRenix and for purposes of securing any Merger Consideration adjustments.

The Merger Agreement contains customary representations, warranties and covenants for a transaction of this nature.

The foregoing description of the Merger Agreement is not complete and is qualified in its entirety by reference to the full text of the Merger Agreement, which will be filed as an exhibit with the Company’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2026.

Item 3.02 Unregistered Sales of Equity Securities.

To the extent required by this Item, the information included in Item 1.01 of this Current Report on Form 8-K is incorporated herein by reference.

The Stock Consideration was issued in private placements exempt from registration under Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”), and/or Regulation D promulgated thereunder, because the offer and sale of such securities did not involve a “public offering” as defined in Section 4(a)(2) of the Securities Act, and other applicable requirements were met. The issuance of the Stock Consideration was made only to those stockholders of iRenix determined to be “accredited investors” as defined pursuant to Rule 501(a) of Regulation D promulgated under the Securities Act.

Item 8.01 Other Events.

On July 8, 2026, the Company issued a press release announcing the completion of the Acquisition. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
