| Item 2.01 | Completion of Acquisition or Disposition of Assets. |
On January 23, 2026, Mirum Pharmaceuticals, Inc. (the “Company”) completed the previously announced acquisition of Bluejay Therapeutics, Inc., a Delaware corporation (“Target”), contemplated by the Agreement and Plan of Merger and Reorganization, dated December 6, 2025 (the “Merger Agreement”), by and among the Company, Bjork Merger Sub I, Inc., a Delaware corporation and a direct wholly owned subsidiary of the Company (“Merger Sub I”), Bjork Merger Sub II, LLC, a Delaware limited liability company and a direct wholly owned subsidiary of the Company (“Merger Sub II”), Target and Fortis Advisors LLC, a Delaware limited liability company, solely in its capacity as the representative, agent and attorney in fact of the Target security holders, pursuant to which, among other things, Merger Sub I merged with and into Target (the “First Merger”), with Target surviving the First Merger and becoming a wholly owned subsidiary of the Company, and, as part of the same overall transaction, Target, as the surviving entity of the First Merger, merged with and into Merger Sub II (the “Second Merger” and collectively with the First Merger, the “Mergers”), with Merger Sub II surviving the Second Merger as a direct wholly owned subsidiary of the Company.
Pursuant to the Merger Agreement, upon the closing of the Mergers, the Company acquired Target’s net cash of approximately $56.6 million and paid or will pay to the holders of Target’s securities up to an aggregate amount of (i) $280.8 million in cash and (ii) 4,673,597 shares of Company common stock, subject to the Company’s receipt of deliverables that are a condition to payment and deduction to satisfy applicable taxes (collectively, the “Upfront Consideration”), and will pay to the holders of Target’s securities in accordance with the Merger Agreement up to an aggregate amount of (a) $25.8 million in cash and (b) 522,375 shares of Company common stock, subject to the Company’s receipt of deliverables that are a condition to payment, deduction to satisfy applicable taxes and certain holdbacks pursuant to the terms and conditions of the Merger Agreement (the “Holdback Consideration”). Pursuant to the Merger Agreement, the Company will pay to the holders of Target’s securities, upon the achievement of certain net sales milestones, milestone payments in an aggregate amount of up to $200 million in cash (together with the Upfront Consideration and the Holdback Consideration, the “Merger Consideration”).
Under the terms of the Merger Agreement, all issued and outstanding Target capital stock (other than any cancelled shares and dissenting shares) and all outstanding Target options (whether vested or unvested) as of immediately prior to the consummation of the Mergers were cancelled in exchange for their applicable pro rata portions of the Merger Consideration as set forth in the Merger Agreement.
Entities affiliated with Frazier Life Sciences IX, L.P., which are associated with a member of the Company’s board of directors and are beneficial owners of more than five percent of the Company’s outstanding capital stock, are Target security holders and received their pro rata portion of the Upfront Consideration and are entitled to receive their pro rata portion of the remainder of the Merger Consideration, including the Holdback Consideration, in accordance with and subject to the terms of the Merger Agreement.
The foregoing description of the Merger Agreement and the Mergers does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K (this “Form 8-K”) and is incorporated herein by reference.
