TOKYO, May 29, 2024 - Coincheck Group B.V. (“CCG” or “Coincheck Group”), a consolidated subsidiary of Monex Group, Inc. (headquarters: Tokyo, Japan; Representative Executive Officer and CEO: Yuko Seimei; the “Company”), which will be a holding company of Coincheck, Inc. (“Coincheck”), is working closely with Thunder Bridge Capital Partners IV, Inc. (“THCP” or “Thunder Bridge”), a special purpose acquisition company (“SPAC”) publicly listed on the Nasdaq Global Market (“Nasdaq”), to complete the previously announced merger which will result in CCG becoming a publicly listed company on Nasdaq (the “CCG De-SPAC Transaction”) pursuant to the Business Combination Agreement, dated March 22, 2022 and amended May 31, 2023, among CCG and certain of its affiliates and THCP (as amended from time to time, the “Business Combination Agreement”). In response to the U.S. Securities and Exchange Commission’s (“SEC”) prolonged registration review process, THCP filed a proxy statement on May 28, 2024 (EDT) in connection with a special meeting of stockholders of THCP that will be held in late June, 2024 (the “THCP Stockholders Meeting”), which includes, among other things, a proposal to amend its amended and restated certificate of incorporation to extend the date by which THCP must consummate a de-SPAC transaction from July 2, 2024 to January 2, 2025 (the “Extension Proposal”). In light of the above, the parties to the Business Combination Agreement have agreed to extend the deadline for completing the CCG De-SPAC Transaction by six months until January 2, 2025, subject to stockholder approval of the Extension Proposal at the THCP Stockholders Meeting. The listing of CCG on Nasdaq through the CCG De-SPAC Transaction will enable us to gain exposure to international investors and to utilize Nasdaq-listed shares as effective currency for recruiting talent and making global acquisitions, thereby further expanding our crypto asset business. We intend to continue our efforts toward completing the CCG De-SPAC Transaction in accordance with the Business Combination Agreement
