BitGo Holdings, Inc.

Item 1.01 Entry into a Material Definitive Agreement. Merger Agreement On August 27, 2026, BitGo Holdings, Inc., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Project Gotham Merger Sub I, Inc., a Delaware corporation and a direct, wholly owned subsidiary of the Company (“Merger Sub 1”), Project Gotham Merger Sub II, LLC, a Delaware limited liability company and a direct, wholly owned subsidiary of the Company (“Merger Sub 2”), NYDIG IHC LLC, a Delaware limited liability company (“Seller”), and NYDIG IF Holdings LLC, a Delaware limited liability company and a direct, wholly owned subsidiary of Seller (the “Target Company”). Pursuant to the Merger Agreement, and subject to the terms and conditions set forth therein, the Company will acquire the Target Company through a two-step merger: (i) Merger Sub 1 will merge with and into the Target Company, with the Target Company continuing as the surviving entity (the “First Merger”), and (ii) immediately thereafter, the Target Company will merge with and into Merger Sub 2, with Merger Sub 2 continuing as the surviving entity and a direct, wholly owned subsidiary of the Company (together with the First Merger, the “Mergers”). Upon consummation of the Mergers, which will occur promptly after the execution of the Merger Agreement, all outstanding limited liability company interests of the Target Company were canceled, and Seller became entitled to receive the merger consideration described below. Consideration: The aggregate consideration payable to Seller in connection with the Mergers consists of: (i) cash consideration of $7,000,000 (subject to a holdback and customary adjustments for indebtedness, cash, net working capital and transaction expenses); (ii) shares of the Company's common stock, par value $0.0001 per share (“Company Common Stock”), issuable at closing (the “Closing Consideration Shares”), with an aggregate value of approximately $35,500,000; (iii) a contingent right to receive $10,000,000 in cash upon the achievement of a specified revenue milestone; and (iv) a contingent right to receive up to $5,000,000 in cash, together with additional shares of Company Common Stock (the “Earn-Out Consideration Shares” and together with the Closing Consideration Shares, the “Shares”) upon the achievement of a second specified revenue milestone. In connection with the closing, the Company also expects to grant certain transferred employees restricted stock units with a target value of $5,000,000 in the aggregate and cash retention awards with an aggregate target value of $5,000,000, which restricted stock units and cash retention awards will vest in full upon the achievement of a second specified revenue milestone. Representations, Warranties, Covenants and Indemnification: The Merger Agreement contains customary representations, warranties and covenants of the parties, as well as customary indemnification provisions subject to certain limitations, including caps and thresholds, and customary exceptions (including for fundamental representations and fraud). The Merger Agreement has been included to provide investors and security holders with information regarding its terms. It is not intended to provide any other factual information about the Company, Seller, the Target Company or their respective subsidiaries or affiliates. The representations, warranties and covenants contained in the Merger Agreement were made only for purposes of the Merger Agreement and as of specific dates, were solely for the benefit of the parties to the Merger Agreement, and may be subject to important qualifications and limitations agreed to by the parties in connection with negotiating its terms, including being qualified by confidential disclosure schedules made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts, as well as by information contained in the Company’s periodic reports filed with the U.S. Securities and Exchange Commission (the “SEC”), and may be subject to standards of materiality applicable to the contracting parties that may differ from those applicable to investors. Investors and security holders are not third-party beneficiaries under the Merger Agreement and should not rely on the representations, warranties and covenants, or any descriptions thereof, as characterizations of the actual state of facts or condition of the Company, Seller, the Target Company or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures. Registration Rights Agreement On August 27, 2026, the Company and Seller entered into a Registration Rights Agreement (the “Registration Rights Agreement”) pursuant to which the Company agreed to file a registration statement (at the Company’s sole expense) registering the Shares (the “Registration Statement”) by the earlier of (i) 180 days after the closing of the Merger and (ii) 5 calendar days after the Company becomes eligible to file a registration statement on Form S-3. In addition, the Company agreed to use its reasonable best efforts to have the Registration Statement and any amendment declared effective by the SEC at the earliest possible date but no later than the earlier of (a) the 60th calendar day following the initial filing date of the Registration Statement if the SEC notifies the Company that it will “review” the Registration Statement and (b) the fifth business day after the date the Company is notified (orally or in writing, whichever is earlier) by the SEC that the Registration Statement will not be “reviewed” or will not be subject to further review. The foregoing description of the Merger Agreement and related transactions contemplated thereby (including, without limitation, the Mergers) and the Registration Rights Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of each of the Merger Agreement and the Registration Rights Agreement, copies of which are filed as Exhibit 2.1 and Exhibit 2.2 to this Current Report on Form 8-K, respectively, and are incorporated herein by reference.
