Introductory Note.

As previously disclosed, on March 22, 2022, Thunder Bridge Capital Partners IV, Inc., a Delaware corporation (“Thunder Bridge” or the “Company”), entered into a Business Combination Agreement (as amended to date, the “Business Combination Agreement”) by and among the Company, Coincheck Group B.V., a Dutch private limited liability company (besloten vennootschap met beperkte aansprakelijkheid) (“PubCo”), M1 Co G.K., a Japanese limited liability company (godo kaisha) (“HoldCo”), Coincheck Merger Sub, Inc., a Delaware corporation (“Merger Sub”), and Coincheck, Inc., a Japanese joint stock company (kabushiki kaisha) (“Coincheck”). The transactions contemplated by the Business Combination Agreement are referred to herein as the “Business Combination”.

On December 10, 2024 (the “Closing Date”), as contemplated by the Business Combination Agreement, Merger Sub merged with and into Thunder Bridge, with Thunder Bridge surviving as a wholly-owned subsidiary of PubCo. Pursuant to the terms set forth in the Business Combination Agreement,, (i) PubCo issued its ordinary shares (the “Ordinary Shares”) to M1 GK and, pursuant to a share exchange, M1 GK, at that time a wholly owned subsidiary of PubCo, exchanged all of its shares of PubCo for all of the outstanding common shares of Coincheck (the “Share Exchange”), resulting in Coincheck becoming a direct wholly owned subsidiary of M1 GK and an indirect wholly-owned subsidiary of PubCo. Immediately after giving effect to the Share Exchange, PubCo changed its legal form from a Dutch private limited liability company (besloten vennootschap met beperkte aansprakelijkheid) to a Dutch public limited liability company (naamloze vennootschap); (ii) Merger Sub merged with and into Thunder Bridge on the Closing Date, with Thunder Bridge continuing as the surviving corporation (the “Merger”); (iii) as a result of the Merger, each outstanding Thunder Bridge share sold as part of a unit in Thunder Bridge’s initial public offering (the “IPO” or “Thunder Bridge’s IPO”; each unit, a “Thunder Bridge Unit”; and each Thunder Bridge share, a “Thunder Bridge Public Share”), for the avoidance of doubt, not including any Thunder Bridge Share held by TBCP IV, LLC, Thunder Bridge’s sponsor (the “Thunder Bridge Sponsor”), as of the date of the Business Combination Agreement (the “Sponsor Shares”), was exchanged for one Ordinary Share; and (iv) as a result of the Merger, each outstanding private warrant exercisable for Thunder Bridge shares (a “Private Warrant”) and each outstanding public warrant exercisable for Thunder Bridge shares sold as part of a unit in Thunder Bridge’s IPO (a “Public Warrant” and the Public Warrants together with the Private Warrants, the “Thunder Bridge Warrants”) became a warrant exercisable for the number of Ordinary Shares that the holder thereof would have received if such warrant had been exercisable and exercised immediately prior to the Business Combination (each such warrant exercisable for Ordinary Shares, a “Public Warrant”).

The description of the Business Combination Agreement contained in this Current Report on Form 8-K does not purport to be complete and is qualified in its entirety by the text of (i) the Business Combination Agreement, which was filed as Exhibit 2.1 to Thunder Bridge’s Current Report on Form 8-K filed on March 22, 2022, and (ii) the First Amendment, which was filed as Exhibit 2.1 to Thunder Bridge’s Current Report on Form 8-K filed on May 31, 2023, (iii) the Second Amendment, which was filed as Exhibit 2.1 to Thunder Bridge’s Current Report on Form 8-K filed on May 30, 2024, (iv) the Third Amendment, which was filed as Exhibit 2.1 to Thunder Bridge’s Current Report on Form 8-K filed on October 11, 2024, each of which is incorporated by reference herein.

Item 1.01 Entry into a Material Definitive Agreement.

The information set forth in the Introductory Note of this Current Report on Form 8-K is incorporated herein by reference.

On the Closing Date, Thunder Bridge, PubCo and Continental Stock Transfer & Trust Company (“Continental”) entered into that certain Warrant Assumption and Amendment Agreement (the “New Warrant Agreement”). The New Warrant Agreement amends that certain Warrant Agreement, dated as of June 29, 2021, by and between Thunder Bridge and Continental (the “Existing Warrant Agreement”), to provide for the assignment by Thunder Bridge of all its rights, title and interest in the warrants of Thunder Bridge to PubCo. Pursuant to the New Warrant Agreement, all Thunder Bridge warrants under the Existing Warrant Agreement will no longer be exercisable for shares of Thunder Bridge’s Class A common stock, but instead will be exercisable for PubCo Ordinary Shares.

The foregoing description of the New Warrant Agreement does not purport to be complete and is qualified in its entirety by reference to the text of the New Warrant Agreement, which is filed as Exhibit 4.1 hereto and is incorporated herein by reference.

Item 1.02 Termination of a Material Definitive Agreement.
