As previously reported on an Current Report on Form 8-K filed on August 7, 2025, on August 7, 2025, CEPO and Pubco entered into subscription agreements with certain investors (the “August Convertible Notes Investors”), pursuant to which the August Convertible Notes Investors have agreed to purchase, upon the terms and subject to the conditions set forth therein, in a private placement, $30.5 million aggregate principal amount of Convertible Notes (such subscriptions, the “August Convertible Notes Private Placement”), to be issued by Pubco pursuant to the same Indenture as the Convertible Notes to be issued pursuant to the July Convertible Notes Subscription Agreements.

August Preferred Stock Private Placement

On August 25, 2025, CEPO and Pubco entered into subscription agreements (the “August Preferred Stock Subscription Agreements”) with certain investors (the “August Preferred Stock Investors”), pursuant to which the August Preferred Stock Investors have agreed to purchase, upon the terms and subject to the conditions set forth therein, in a private placement, an aggregate of approximately 0.48 million shares of Preferred Stock with an aggregate principal amount of approximately $48.3 million, at a purchase price of $85.00 per share, for an aggregate purchase price of approximately $41.05 million (the “August Preferred Stock Private Placement”). The Preferred Stock to be issued by Pubco pursuant to the August Preferred Stock Subscription Agreements will be governed by the same Certificate of Designations as the Preferred Stock subscribed for pursuant to the July Preferred Stock Subscription Agreement and which was included as an exhibit to the August Preferred Stock Subscription Agreements.

Pursuant to the August Preferred Stock Subscription Agreements, Pubco has agreed to certain obligations to register and maintain the registration of the Preferred Stock and the shares of Class A common stock, par value $0.01 per share, of Pubco (“Pubco Class A Stock”) issuable upon conversion of such Preferred Stock including that, within 30 calendar days after the Closing, Pubco will file with the SEC (at Pubco’s sole cost and expense) a registration statement registering the resale of the Preferred Stock and the shares of Pubco Class A Stock underlying the Preferred Stock, and Pubco shall use its commercially reasonable efforts to have such registration statement declared effective as soon as practicable after the filing thereof, but no later than 90 calendar days after the Closing, which may be extended an additional 90 calendar days depending on the level of SEC review involved. Each August Preferred Stock Subscription Agreement shall terminate and be void and of no further force and effect upon the earliest to occur of (i) such date and time as the Business Combination Agreement is terminated in accordance with its terms; (ii) the mutual written agreement of the respective parties to terminate such agreement; or (iii) July 16, 2026.

The form of August Preferred Stock Subscription Agreement is filed as Exhibit 10.1 to this Current Report on Form 8-K, and the foregoing description thereof is qualified in its entirety by reference to the full text of the form of August Preferred Stock Subscription Agreement and the terms of which are incorporated by reference herein.

Item 3.02 Unregistered Sale of Equity Securities

The disclosure set forth above in Item 1.01 of this Current Report on Form 8-K is incorporated by reference herein, to the extent applicable. The Convertible Notes and the Preferred Stock that may be issued in connection with the Second Convertible Notes Option (as defined below), the Preferred Stock Option (as defined below), the Unexercised Option (as defined below), and the August Preferred Stock Private Placement will not be registered under the Securities Act, in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act and/or Regulation D promulgated thereunder.

Item 8.01 Other Events.

Contemporaneously with the execution of the Business Combination Agreement, CEPO and Pubco entered into the July Convertible Notes Subscription Agreements, pursuant to which Pubco granted the July Convertible Notes Investors (i) an option to purchase additional Convertible Notes in an aggregate principal amount of up to $125 million, exercisable within 15 days following the execution of the July Convertible Notes Subscription Agreements (the “First Convertible Notes Option”), (ii) an option to purchase additional Convertible Notes in an aggregate principal amount of up to $125 million, exercisable within 30 days following the execution of the Convertible Notes Subscription Agreements (the “Second Convertible Notes Option” and, together with the First Convertible Notes Option, the “Convertible Notes Options”) and (iii) an option (the “Preferred Stock Option” and, together with the Convertible Notes Options, the “Options”) to purchase up to 3,200,000 shares of Preferred Stock with an aggregate principal amount of $320 million to be issued by Pubco pursuant to and on the terms set forth in the Certificate of Designations at a purchase price of $85.00 per share, exercisable within 30 days following the execution of the July Convertible Notes Subscription Agreements, in each case, on a pro rata basis based on such July Convertible Notes Investor’s participation in the July Convertible Notes Private Placement. Pursuant to the July Convertible Notes Subscription Agreements, if any July Convertible Notes Investors should elect not to exercise their pro rata share of any Option, such unexercised portion of such Option (the “Unexercised Option”) would be offered to and may be exercised by the remaining July Convertible Notes Investors pro rata to their participation in the July Convertible Note Private Placement and the applicable Option during and until 5:00 p.m. New York time on the Business Day immediately after the expiry of the applicable Option.

Exercise of the Options

First Convertible Notes Option

As previously reported on a Current Report on Form 8-K filed on August 7, 2025 with the SEC, certain July Convertible Note Investors exercised their pro rata share of the First Convertible Notes Option and the Unexercised Option with respect to the First Convertible Notes Option to purchase additional Convertible Notes in an aggregate principal amount of $34.87 million.

Second Convertible Notes Option

As of August 18, 2025, certain July Convertible Notes Investors exercised their pro rata share of the Second Convertible Notes Option and the Unexercised Option for the Second Convertible Notes Option to purchase additional Convertible Notes in an aggregate principal amount of $9.323 million. The Convertible Notes to be issued pursuant to the Second Convertible Notes Option will be governed by the same Indenture and the related collateral will be governed by the same security agreement as the Convertible Notes initially subscribed for pursuant to the July Convertible Notes Subscription Agreements.

Preferred Stock Option

Further, as of August 18, 2025, certain July Convertible Notes Investors exercised their pro rata share of the Preferred Stock Option and the Unexercised Option for the Preferred Stock Option to purchase an aggregate of approximately 2.217 million shares of Preferred Stock with an aggregate principal amount of approximately $221.7 million at a purchase price of $85.00 per share for a total aggregate purchase price of approximately $188.5 million. The Preferred Stock to be issued pursuant to the Preferred Stock Option will be governed by the same Certificate of Designations as the Preferred Stock subscribed for pursuant to the July Preferred Stock Subscription Agreement and which was included as an exhibit to the July Preferred Stock Subscription Agreement.

The closing of the July Convertible Notes Private Placement (including the sale and issuance of Convertible Notes pursuant to the Convertible Notes Options and the sale and issuance of Preferred Stock pursuant to the Preferred Stock Option) is contingent upon the satisfaction of all closing conditions to consummate the transactions as set forth in the Business Combination Agreement and the July Convertible Notes Subscription Agreements (which include the July Convertible Notes Investors’ consent to any amendments, modifications or waivers to the terms of the Business Combination Agreement that would reasonably be expected to materially and adversely affect the economic benefits of the July Convertible Notes Investors), among other customary closing conditions.

Additional Information and Where to Find It

Pubco and Newco intend to file with the SEC a Registration Statement on Form S-4 (as may be amended, the “Registration Statement”), which will include a preliminary proxy statement of CEPO and a prospectus (the “Proxy Statement/Prospectus”) in connection with the business combination (the “Business Combination”) among Pubco, CEPO, Newco and the other parties named therein, the July Convertible Notes Private Placement (including the sale and issuance of Convertible Notes pursuant to the Convertible Notes Options), the July Preferred Stock Private Placement, the Newco Private Placement, the CEPO Equity PIPEs, the August Convertible Notes Private Placement and the August Preferred Stock Private Placement (together, the “Private Placement Investments, together with the Business Combination, the “Proposed Transactions”). The definitive proxy statement and other relevant documents will be mailed to shareholders of CEPO as of a record date to be established for voting on the Business Combination and other matters as will be described in the Proxy Statement/Prospectus. CEPO and/or Pubco will also file other documents regarding the Proposed Transactions with the SEC. This Current Report on Form 8-K (this “Report”) does not contain all of the information that should be considered concerning the Proposed Transactions and is not intended to form the basis of any investment decision or any other decision in respect of the Proposed Transactions. BEFORE MAKING ANY VOTING OR INVESTMENT DECISION, SHAREHOLDERS OF CEPO AND OTHER INTERESTED PARTIES ARE URGED TO READ, WHEN AVAILABLE, THE PRELIMINARY PROXY STATEMENT/PROSPECTUS, AND AMENDMENTS THERETO, AND THE DEFINITIVE PROXY STATEMENT/PROSPECTUS AND ALL OTHER RELEVANT DOCUMENTS FILED OR THAT WILL BE FILED WITH THE SEC IN CONNECTION WITH CEPO’S SOLICITATION OF PROXIES FOR THE EXTRAORDINARY GENERAL MEETING OF ITS SHAREHOLDERS TO BE HELD TO APPROVE THE PROPOSED TRANSACTIONS AND OTHER MATTERS AS DESCRIBED IN THE PROXY STATEMENT/PROSPECTUS BECAUSE THESE DOCUMENTS WILL CONTAIN IMPORTANT INFORMATION ABOUT CEPO, NEWCO, PUBCO AND THE PROPOSED TRANSACTIONS. Investors and security holders will also be able to obtain copies of the Registration Statement and the Proxy Statement/Prospectus and all other documents filed or that will be filed with the SEC by CEPO, Pubco and Newco, without charge, once available, on the SEC’s website at www.sec.gov or by directing a request to: Cantor Equity Partners I, Inc., 110 East 59th Street, New York, NY 10022; e-mail: CantorEquityPartners@cantor.com, or upon written request to BSTR Holdings, Inc., via email at bstr@blockstreamcapitalpartners.com, respectively.

NEITHER THE SEC NOR ANY STATE SECURITIES REGULATORY AGENCY HAS APPROVED OR DISAPPROVED THE PROPOSED TRANSACTIONS DESCRIBED HEREIN, PASSED UPON THE MERITS OR FAIRNESS OF THE BUSINESS COMBINATION OR ANY RELATED PROPOSED TRANSACTIONS OR PASSED UPON THE ADEQUACY OR ACCURACY OF THE DISCLOSURE IN THIS REPORT. ANY REPRESENTATION TO THE CONTRARY CONSTITUTES A CRIMINAL OFFENSE.

The Convertible Notes and shares of Preferred Stock to be issued by Pubco, the CEPO Class A Ordinary Shares to be issued by CEPO and the Newco Class A Interests to be issued by Newco, in each case, pursuant to the Private Placement Investments, as well as the non-voting units of Newco to be issued in exchange for the Newco Class A Interests at the closing of the Business Combination, pursuant to the Business Combination Agreement, have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act.

Participants in the Solicitation

CEPO, Pubco, Newco and their respective directors and executive officers may be deemed under SEC rules to be participants in the solicitation of proxies from CEPO’s shareholders in connection with the Business Combination. A list of the names of such directors and executive officers, and information regarding their interests in the Business Combination and their ownership of CEPO’s securities are, or will be, contained in CEPO’s filings with the SEC, including CEPO’s Annual Report on Form 10-K and Quarterly Reports on Form 10-Q. Additional information regarding the interests of the persons who may, under SEC rules, be deemed participants in the solicitation of proxies of CEPO’s shareholders in connection with the Proposed Transactions, including the names and interests of Newco and Pubco’s directors and executive officers, will be set forth in the Proxy Statement/Prospectus, which is expected to be filed by CEPO, Pubco and Newco with the SEC. Investors and security holders may obtain free copies of these documents as described in the preceding paragraph.

No Offer or Solicitation

The information contained in this Report is for informational purposes only and is not a proxy statement or solicitation of a proxy, consent or authorization with respect to any securities or in respect of the Proposed Transactions and shall not constitute an offer to sell or exchange, or a solicitation of an offer to buy or exchange the securities of CEPO, Pubco or Newco, or any commodity or instrument or related derivative, nor shall there be any sale of any such securities in any state or jurisdiction in which such offer, solicitation, sale or exchange would be unlawful prior to registration or qualification under the securities laws of such state or jurisdiction. No offer of securities shall be made except by means of a prospectus meeting the requirements of the Securities Act or an exemption therefrom. Investors should consult with their counsel as to the applicable requirements for a purchaser to avail itself of any exemption under the Securities Act.

Forward-Looking Statements

This Report contains certain forward-looking statements within the meaning of the U.S. federal securities laws with respect to the parties and the Proposed Transactions, including, expectations, hopes, beliefs, intentions, plans, prospects, financial results, strategies and other statements relating to CEPO, Pubco, Newco and the Proposed Transactions and statements regarding the anticipated benefits and timing of the completion of the Proposed Transactions, the assets held by Newco, the terms of the Indenture and the Security Agreement, the listing of any securities of Pubco on an applicable securities exchange, Pubco’s plans and use of proceeds, and the upside potential and opportunity for investors relating to participation in the Private Placement Investments or any future securities resulting from any Proposed Transactions, any potential future capital raises, any proposed transaction structures and offering terms, future financial condition and performance and expected financial impacts of the Proposed Transactions, the satisfaction of the closing conditions of the Proposed Transactions, and any expectations, intentions, strategies, assumptions or beliefs about future events, results of operations or performance or that do not solely relate to historical or current facts.

Forward-looking statements are predictions, projections and other statements about future events or conditions that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. Many factors could cause actual future events to differ materially from the forward-looking statements in this Report, including, but not limited to: the risk that the Proposed Transactions may not be completed in a timely manner or at all, which may adversely affect the price of CEPO’s securities; the risk that the Business Combination may not be completed by CEPO’s business combination deadline; the failure by the parties to the Business Combination to satisfy the conditions to the consummation of the Business Combination, including the approval of CEPO’s shareholders, or any of the Private Placement Investments; failure to realize the anticipated benefits of the Proposed Transactions; the level of redemptions of CEPO’s public shareholders which may reduce the public float of, reduce the liquidity of the trading market of, and/or maintain the quotation, listing, or trading of the CEPO Class A Ordinary Shares or the Pubco Class A Stock; the lack of a third-party fairness opinion in determining whether or not to pursue the Business Combination; the failure of Pubco to obtain or maintain the listing of its securities any stock exchange on which Pubco Class A Stock will be listed after closing of the Business Combination; costs related to the Proposed Transactions and as a result of becoming a public company; changes in business, market, financial, political and regulatory conditions; risks relating to Pubco’s anticipated operations and business, including the highly volatile nature of the price of Bitcoin; the risk that Pubco’s stock price will be highly correlated to the price of Bitcoin and the price of Bitcoin may decrease at any time after the closing of the Proposed Transactions; risks related to increased competition in the industries in which Pubco will operate; risks relating to significant legal, commercial, regulatory and technical uncertainty regarding Bitcoin; risks relating to the treatment of crypto assets for U.S. and foreign tax purposes; risks that after consummation of the Business Combination, Pubco experiences difficulties managing its growth and expanding operations; challenges in implementing Pubco’s business plan, including Bitcoin-related advisory services and other Bitcoin-related services, due to operational challenges, significant competition and regulation; being considered to be a “shell company” by any stock exchange on which Pubco Class A Stock will be listed or by the SEC, which may impact the ability to list Pubco Class A Stock and restrict reliance on certain rules or forms in connection with the offering, sale or resale of securities; the outcome of any potential legal proceedings that may be instituted against CEPO, Pubco, Newco or others following announcement of the Business Combination; and those risk factors discussed in documents of CEPO, Pubco or Newco filed, or to be filed, with the SEC.

The foregoing list of risk factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties described in the “Risk Factors” section of the final prospectus of CEPO dated as of January 6, 2025 and filed by CEPO with the SEC on January 7, 2025, CEPO’s Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q on file, and to be filed, with the SEC and the Proxy Statement/Prospectus that will be filed by Pubco and Newco, and other documents filed by CEPO, Pubco and Newco from time to time with the SEC. These filings do or will identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. There may be additional risks that none of CEPO, Pubco and Newco presently know or that none of CEPO, Pubco and Newco currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements.

Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and none of CEPO, Pubco and Newco assume any obligation or intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise. None of CEPO, Pubco and Newco give any assurance that any of CEPO, Pubco or Newco will achieve its expectations. The inclusion of any statement in this Report does not constitute an admission by CEPO, Pubco, Newco or any other person that the events or circumstances described in such statement are material.
