Pursuant to the Business Combination Agreement, (i) Tether has purchased 4,812.220927 Bitcoin (the “Initial PIPE Bitcoin”) for an aggregate purchase price of $458.7 million (the “Initial PIPE Net Proceeds”), being equal to the aggregate gross cash proceeds of the Initial Convertible Notes PIPE and the April Equity PIPE less a holdback of $52 million, and, at Closing, Tether will sell the Initial PIPE Bitcoin to Pubco for an amount equal to the Initial PIPE Net Proceeds, and (ii) Tether has purchased 917.47360612 Bitcoin (the “Option PIPE Bitcoin”) for an aggregate purchase price of $99.5 million (the “Option PIPE Net Proceeds”), being equal to the gross proceeds of the Option Notes less a holdback of $500,000, and, at Closing, Tether will sell the Option PIPE Bitcoin to Pubco at a purchase price equal to the Option PIPE Net Proceeds, in exchange for additional shares of Pubco Class A Stock and Pubco Class B Stock.

With the inclusion of the Subscription Notes, Option Notes, Exchange Notes and Engagement Letter Notes, the total aggregate principal value of the Convertible Notes will be $486.5 million.

The Sponsor Support Agreement also provides that, among other things, (i) the Sponsor will vote its CEP Class A Ordinary Shares, and its Class B ordinary shares of CEP, par value $0.0001 per share (“CEP Class B Ordinary Shares” and, together with the CEP Class A Ordinary Shares, the “CEP Ordinary Shares”) in favor of the adoption and approval of the Business Combination Agreement and the Business Combination and each of the other proposals to be approved by CEP Shareholders at the Meeting (the “CEP Shareholder Approval Matters”), (ii) the Sponsor will vote its CEP Ordinary Shares against any alternative transactions, (iii) the Sponsor will comply with the restrictions imposed by the letter agreement, dated as of August 12, 2024, by and among CEP, the Sponsor and the then current directors and executive officers of CEP (the “Insider Letter”), including with respect to the restrictions on transfer and redemption of CEP Ordinary Shares in connection with the Business Combination, (iv) prior to the Closing, the Sponsor will amend the Insider Letter to reduce the post-Closing lock-up period applicable to the shares of Pubco Class A Stock received by the Sponsor in exchange for its CEP Class B Ordinary Shares (the “Founder Shares”) from 12 months to six months, and (v) subject to and conditioned upon the Closing, any loans outstanding from the Sponsor to CEP shall be repaid as follows: (a) with respect to the amended and restated promissory note, dated November 5, 2024, and effective as of August 12, 2024 (the “Sponsor Loan”), the aggregate amount owed by CEP, as set forth on the pre-Closing statement to be delivered by CEP prior to the Closing (the “CEP Pre-Closing Statement”), will be automatically converted, immediately prior to the CEP Merger, into CEP Class A Ordinary Shares at $10.00 per share, and that upon the issuance and delivery of such CEP Class A Ordinary Shares to the Sponsor, the Sponsor Loan will be deemed satisfied in full, provided, however, that the portion of the Sponsor Loan that is drawn by or on behalf of CEP to pay for any fees, costs or expenses of the U.S. Securities and Exchange Commission (the “SEC”) or Nasdaq pursuant to the Business Combination Agreement will be repaid in cash at the Closing in accordance with the Business Combination Agreement and (b) with respect to all other loans of the Sponsor to CEP, all amounts outstanding thereunder as of the Closing, as set forth on the CEP Pre-Closing Statement, will be repaid in cash at the Closing in accordance the Business Combination Agreement.

On June 25, 2025, Pubco, CEP and the Sponsor entered into the Sponsor Support Agreement Amendment, pursuant to which the Sponsor has agreed to forfeit a number of CEP Class A Ordinary Shares it receives upon conversion of its CEP Class B Ordinary Shares so that such number of CEP Class A Ordinary Shares retained by the Sponsor equals the lesser of (a) 25% of the sum of the number of Public Shares not subject to redemption in connection with the Closing and the number of CEP Class A Ordinary Shares issued in the Equity PIPE and (b) the sum of (i) 7,084,804 and (ii) 1.5% of the gross proceeds received by Pubco and CEP pursuant to the April PIPE Investments, divided by $10.00.

Contemporaneously with the execution of the Business Combination Agreement, Tether and SoftBank entered into a sale and purchase agreement, as amended and restated on June 23, 2025, pursuant to which, among other things, immediately following the Closing, Tether will transfer to SoftBank an equal number of shares of Pubco Class A Stock and Pubco Class B Stock, and SoftBank will pay Tether consideration calculated based on a formula described thereunder.

On April 22, 2025, along with the Business Combination Agreement, Tether, Bitfinex and SoftBank entered into the Governance Term Sheet, which sets out the main terms upon which Pubco will prepare the Proposed Organizational Documents, which will be adopted at or prior to Closing. At Closing, Tether, Bitfinex and SoftBank will enter into the Governance Agreement, which will implement the terms of the Governance Term Sheet. Pursuant to the Governance Agreement, Pubco will issue two (2) classes of shares of Pubco Stock, with different voting and economic rights attached to them. The shares of Pubco Class A Stock will have no voting rights other than as required by applicable law, until all shares of Pubco Class B Stock are canceled, whereas, holders of shares of Pubco Class B Stock will be entitled to one vote per share. Once all shares of Pubco Class B Stock are canceled, holders of Pubco Class A Stock will acquire full voting rights. Holders of Pubco Class A Stock will be entitled to receive distributions in proportion to the number of shares of Pubco Class A Stock held by them, whereas, holders of Pubco Class B Stock will not have any economic rights. In addition, the shares of Pubco Class A Stock will be listed for trading and will be freely transferable, subject to the terms of the Lock-Up Agreements, the Insider Letter and any restrictions pursuant to applicable laws. The shares of Pubco Class B Stock will not be listed or freely transferable, except to Affiliates. The parties agreed to take all necessary action so that effective as of the Closing, the board of directors of Pubco will consist of seven individuals, six of which are to be designated by the Sellers and SoftBank, with the final director to be the chief executive officer of Pubco.

On July 26, 2025, the parties to the Business Combination Agreement entered into Amendment No. 1 to the Business Combination Agreement, which amends the Business Combination Agreement, among other things, to provide that the Additional PIPE Bitcoin Purchase Price used to determine the value of Tether’s contribution of the Additional PIPE to Pubco at the Closing and the number of shares of Pubco Class A Stock and Pubco Class B Stock to be issued to Tether at the Closing in exchange for the sale of the Additional PIPE Bitcoin by Tether to Pubco shall be based on $84,863.57, which is equal to the average Bitcoin price for the ten-day period ending April 21, 2025, the day prior to the date of the Business Combination Agreement (the “Signing Bitcoin Price”), rather than on the aggregate amount Tether paid to purchase the Additional PIPE Bitcoin.

Concurrently with the Closing, Tether, Bitfinex and SoftBank will each enter into a Lock-Up Agreement with Pubco, pursuant to which each Seller and SoftBank will agree that the shares of Pubco Class A Stock received by each Seller and the shares of Pubco Class A Stock transferred by Tether to SoftBank will be locked-up and subject to transfer restrictions, as described below, subject to certain exceptions.

Concurrently with the Closing, CEP, Pubco, the Sponsor, each Seller and SoftBank will enter into an Amended and Restated Registration Rights Agreement that will amend and restate the registration rights agreement, dated as of August 12, 2024, by and between CEP and the Sponsor.

Concurrently with the Closing, Pubco and Tether will enter into a Services Agreement, pursuant to which Tether will agree to provide, or cause to be provided, certain services to Pubco and its subsidiaries in exchange for a services fee in the amount of $30,000 per calendar quarter or such other amount as may be agreed by the parties thereto.

Upon the completion of the Business Combination and the consummation of the PIPE Investments, and assuming, among other things, that no Public Shareholders exercise redemption rights with respect to their Public Shares upon completion of the Business Combination, that all PIPE Investors fund their commitments in their PIPE Subscription Agreements, that no Convertible Notes are converted into shares of Pubco Class A Stock and that no shares of Pubco Class A Stock are issued pursuant to the Twenty One Capital, Inc. 2025 Incentive Award Incentive Plan, as amended from time to time, to become effective upon the Closing (the “Incentive Plan”), (i) Public Shareholders, (ii) the April Equity PIPE Investors, (iii) the June Equity PIPE Investors, (iv) the Sponsor and its Affiliates, (v) the directors and officers of CEP, (vi) the Sellers and (vii) SoftBank will own, pursuant to the respective agreements, shares of the issued and outstanding shares of Pubco Class A and Class B Common Stock.

Each holder of shares of Pubco Class A Stock will have no voting rights except as required by the Texas Business Organizations Code (“TBOC”), until all shares of Pubco Class B Stock are canceled. Once all shares of Pubco Class B Stock are canceled, holders of Pubco Class A Stock will acquire full voting rights. Each holder of shares of Pubco Class B Stock will be entitled to one vote for each share of Pubco Class B Stock held of record by such holder on all matters on which stockholders are generally entitled to vote.

The price per share of Pubco Class A Stock is $10.00 per share for (i) Public Shareholders, (ii) the April Equity PIPE Investors, (iii) the Sponsor and its Affiliates, (iv) the directors and officers of CEP, (v) the Sellers and (vi) SoftBank, and $21.00 per share for the June Equity PIPE Investors.

The value of the consideration that the Public Shareholders are each receiving in connection with the Business Combination is thus $10.00 per share.

The Business Combination will be accounted for as a reverse recapitalization, in accordance with U.S. GAAP. Under this method of accounting, CEP will be treated as the acquired company for financial reporting purposes, and Twenty One will be the accounting acquirer. Accordingly, the Business Combination was treated as the equivalent of Twenty One issuing stock for the net assets of CEP, accompanied by a recapitalization. The net assets of CEP were stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination were those of Twenty-One.

If Pubco’s application for listing is approved, shares of Pubco Class A Stock are expected to be traded on NYSE, Nasdaq or another national securities exchange under the symbol “XXI.” The CEP Class A Ordinary Shares will not trade after the Closing.

On April 22, 2025, along with the Business Combination Agreement, Tether, Bitfinex and SoftBank entered into the Governance Term Sheet, which sets out the main terms upon which Pubco will prepare the Proposed Organizational Documents, which will be adopted at or prior to Closing. At Closing, Tether, Bitfinex and SoftBank will enter into the Governance Agreement, which will implement the terms of the Governance Term Sheet. Pursuant to the Governance Agreement, Pubco will issue two (2) classes of shares of Pubco Stock, with different voting and economic rights attached to them. The shares of Pubco Class A Stock will have no voting rights other than as required by applicable law, until all shares of Pubco Class B Stock are canceled, whereas, holders of shares of Pubco Class B Stock will be entitled to one vote per share. Once all shares of Pubco Class B Stock are canceled, holders of Pubco Class A Stock will acquire full voting rights. Holders of Pubco Class A Stock will be entitled to receive distributions in proportion to the number of shares of Pubco Class A Stock held by them, whereas, holders of Pubco Class B Stock will not have any economic rights. In addition, the shares of Pubco Class A Stock will be listed for trading and will be freely transferable, subject to the terms of the Lock-Up Agreements, the Insider Letter and any restrictions pursuant to applicable laws. The shares of Pubco Class B Stock will not be listed or freely transferable, except to Affiliates. The parties agreed to take all necessary action so that effective as of the Closing, the board of directors of Pubco will consist of seven individuals, six of which are to be designated by the Sellers and SoftBank, with the final director to be the chief executive officer of Pubco.

On July 26, 2025, the parties to the Business Combination Agreement entered into Amendment No. 1 to the Business Combination Agreement, which amends the Business Combination Agreement, among other things, to provide that the Additional PIPE Bitcoin Purchase Price used to determine the value of Tether’s contribution of the Additional PIPE to Pubco at the Closing and the number of shares of Pubco Class A Stock and Pubco Class B Stock to be issued to Tether at the Closing in exchange for the sale of the Additional PIPE Bitcoin by Tether to Pubco shall be $84,863.57, which is equal to the average Bitcoin price for the ten-day period ending April 21, 2025, the day prior to the date of the Business Combination Agreement (the “Signing Bitcoin Price”), rather than on the aggregate amount Tether paid to purchase the Additional PIPE Bitcoin.

Concurrently with the Closing, Tether, Bitfinex and SoftBank will each enter into a Lock-Up Agreement with Pubco, pursuant to which each Seller and SoftBank will agree that the shares of Pubco Class A Stock received by each Seller and the shares of Pubco Class A Stock transferred by Tether to SoftBank will be locked-up and subject to transfer restrictions, as described below, subject to certain exceptions.

Concurrently with the Closing, CEP, Pubco, the Sponsor, each Seller and SoftBank will enter into an Amended and Restated Registration Rights Agreement that will amend and restate the registration rights agreement, dated as of August 12, 2024, by and between CEP and the Sponsor.

Concurrently with the Closing, Pubco and Tether will enter into a Services Agreement, pursuant to which Tether will agree to provide, or cause to be provided, certain services to Pubco and its subsidiaries in exchange for a services fee in the amount of $30,000 per calendar quarter or such other amount as may be agreed by the parties thereto.

Upon the completion of the Business Combination and the consummation of the PIPE Investments, and assuming, among other things, that no Public Shareholders exercise redemption rights with respect to their Public Shares upon completion of the Business Combination, that all PIPE Investors fund their commitments in their PIPE Subscription Agreements, that no Convertible Notes are converted into shares of Pubco Class A Stock and that no shares of Pubco Class A Stock are issued pursuant to the Twenty One Capital, Inc. 2025 Incentive Award Incentive Plan, as amended from time to time, to become effective upon the Closing (the “Incentive Plan”), (i) Public Shareholders, (ii) the April Equity PIPE Investors, (iii) the June Equity PIPE Investors, (iv) the Sponsor and its Affiliates, (v) the directors and officers of CEP, (vi) the Sellers and (vii) SoftBank will own, pursuant to the respective agreements, shares of the issued and outstanding shares of Pubco Class A and Class B Common Stock.

Each holder of shares of Pubco Class A Stock will have no voting rights except as required by the Texas Business Organizations Code (“TBOC), until all shares of Pubco Class B Stock are canceled. Once all shares of Pubco Class B Stock are canceled, holders of Pubco Class A Stock will acquire full voting rights. Each holder of shares of Pubco Class B Stock will be entitled to one vote for each share of Pubco Class B Stock held of record by such holder on all matters on which stockholders are generally entitled to vote.

The price per share of Pubco Class A Stock is $10.00 per share for (i) Public Shareholders, (ii) the April Equity PIPE Investors, (iii) the Sponsor and its Affiliates, (iv) the directors and officers of CEP, (v) the Sellers and (vi) SoftBank, and $21.00 per share for the June Equity PIPE Investors.

The value of the consideration that the Public Shareholders are each receiving in connection with the Business Combination is thus $10.00 per share.

The Business Combination will be accounted for as a reverse recapitalization, in accordance with U.S. GAAP. Under this method of accounting, CEP will be treated as the acquired company for financial reporting purposes, and Twenty One will be the accounting acquirer. Accordingly, the Business Combination was treated as the equivalent of Twenty One issuing stock for the net assets of CEP, accompanied by a recapitalization. The net assets of CEP were stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination were those of Twenty-One.

If Pubco’s application for listing is approved, shares of Pubco Class A Stock are expected to be traded on NYSE, Nasdaq or another national securities exchange under the symbol “XXI.” The CEP Class A Ordinary Shares will not trade after the Closing.
