Item 1.02 Termination of a Material Definitive Agreement.

On May 19, 2026, in connection with the consummation of the Transaction (as defined below), that certain Governance Agreement, dated December 8, 2025 (the “Governance Agreement”), by and among Twenty One Capital, Inc. (the “Company”), Tether Investments, S.A. de C.V., an El Salvador sociedad anónima de capital variable (“Tether Investments”), Stellar Beacon LLC, a Delaware limited liability company (“SoftBank”) and iFinex, Inc., a British Virgin Islands company (“Bitfinex”), was terminated in accordance with the terms of the Governance Agreement.

As previously disclosed, pursuant to the Governance Agreement, matters over which Tether Investments, Bitfinex and SoftBank may individually, directly or indirectly, exercise significant influence included: (i) the election of the directors on the Company’s board of directors; (ii) amendments to the Company’s Certificate of Formation and bylaws; (iii) changes in the size of the Company’s board of directors; and (iv) matters identified as 20% Reserved Matters and 10% Reserved Matters (each as defined in the Governance Agreement).

The descriptions of the Governance Agreement in this Current Report on Form 8-K do not purport to be complete and are subject to, and qualified in their entirety by reference to, the full text of the Governance Agreement, a copy of which is included as Exhibit 10.18 to the Company’s Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission (the “SEC”) on December 12, 2025 and incorporated herein by reference.

Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing

As previously disclosed in the Company’s Current Report on Form 8-K filed on March 16, 2026, each of Jared Roscoe and Vikas J. Parekh executed and delivered a letter of resignation from the Company’s board of directors and all applicable committees thereof, which resignation would become effective immediately upon request by SoftBank. On May 19, 2026, in connection with the consummation of the Transaction, SoftBank requested the resignation of Mr. Roscoe and Mr. Parekh and their resignation from the Company’s board of directors and all applicable committees thereof become effective immediately as of the consummation of the Transaction, pursuant to the Governance Agreement. The resignations of Mr. Roscoe and Mr. Parekh are not related to any disagreements with the Company on any matter relating to its operations, policies or practices.

Prior to his resignation, Mr. Roscoe served as a member of the audit committee, the compensation committee and the nominating and corporate governance committee of the Company’s board of directors.

Prior to Mr. Roscoe’s resignation, the audit committee of the Company’s board of directors was comprised of two independent directors, the minimum number required during the transition period for compliance with Section 303A.07(a) of the NYSE Listed Company Manual, as provided in Section 303A.00 of the NYSE Listed Company Manual. As a result of Mr. Roscoe’s resignation, the audit committee does not have two independent members as required under NYSE rules.

The Company notified the NYSE of the resulting non-compliance on May 20, 2026. The Company expects to appoint, as soon as practicable, an additional member to the audit committee who meets the independence requirements of Rule 10A-3 under the Securities Exchange Act of 1934, as amended, and Section 303A.02 of the Listed Company Manual.

Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

The information set forth under Item 3.01 of this Current Report on Form 8-K is incorporated by reference into this Item 5.02 to the extent required herein. The resignation of Mr. Roscoe and Mr. Parekh and their resignation from the Company’s board of directors and all applicable committees thereof became effective on May 19, 2026.
