Updated Pro Forma Financial Statements

As previously disclosed, on June 30, 2025, the Company completed its previously announced acquisition contemplated by the Agreement and Plan of Merger, dated December 11, 2024, as amended by that certain First Amendment to Agreement and Plan of Merger, dated May 5, 2025 (as amended, the “Merger Agreement”), by and among the Company, Hura Merger Sub I, Inc., a Delaware corporation and a direct wholly-owned subsidiary of the Company (“Merger Sub I”), Hura Merger Sub II, LLC, a Delaware limited liability company and direct wholly-owned subsidiary of the Company (“Merger Sub II”), Kineta, Inc., a Delaware corporation (“Kineta”), and Craig Philips, solely in his capacity as the representative, agent and attorney-in-fact of the stockholders of Kineta. Pursuant to the terms of the Merger Agreement, among other things, (a) Merger Sub I merged with and into Kineta (the “First Merger”), with Kineta being the surviving corporation of the First Merger, also known as the “Surviving Entity” and (b) immediately following the First Merger, the Surviving Entity merged with and into Merger Sub II (the “Second Merger”, and together with the First Merger, the “Mergers”), with Merger Sub II being the surviving company of the Second Merger.

On April 8, 2026, the Company filed a Current Report on Form 8-K (the “Prior Report”) to provide its unaudited pro forma condensed combined statement of operations for the year ended December 31, 2025 on a pro forma basis as if the Mergers had been consummated on January 1, 2025 (the “Prior Pro Formas”). The Company is filing this amendment to the Prior Report solely to amend the Prior Pro Formas to correct certain errors contained therein. Such revised pro formas are filed as Exhibit 99.1 to this amended Current Report, which replaces the Exhibit 99.1 filed with the Prior Report in its entirety. This amendment does not include any other updates or amendments to the Prior Report.
