Other Events.

As previously disclosed on September 8, 2025, Churchill Capital Corp X (“Churchill” or “we”) entered into an Agreement and Plan of Merger and Reorganization (the “Merger Agreement”) by and among Churchill, AH Merger Sub I, Inc., a Delaware corporation and direct, wholly-owned subsidiary of Churchill, AH Merger Sub II, LLC, a Delaware limited liability company and direct, wholly-owned subsidiary of Churchill and ColdQuanta, Inc., a Delaware corporation (the “Company”).

On November 4, 2025, we and the Company issued a joint press release announcing the confidential submission by Churchill and the Company of a draft registration on Form S-4 with the Securities and Exchange Commission (the “SEC”) on October 29, 2025, in connection with the Merger Agreement and the transactions contemplated thereby. A copy of the press release is attached hereto as Exhibit 99.1 and incorporated by reference herein.

Additional Information and Where to Find It

The proposed transaction will be submitted to shareholders of Churchill for their consideration. Churchill intends to file a registration statement on Form S-4 (the “Registration Statement”) with the SEC, which will include preliminary and definitive proxy statements to be distributed to Churchill’s shareholders in connection with Churchill’s solicitation of proxies for the vote by Churchill’s shareholders in connection with the proposed transaction and other matters to be described in the Registration Statement, as well as the prospectus relating to the offer of the securities to be issued to Company stockholders in connection with the completion of the proposed transaction. After the Registration Statement has been filed and declared effective, a definitive proxy statement/prospectus and other relevant documents will be mailed to Company stockholders and Churchill shareholders as of the record date established for voting on the proposed transaction. Before making any voting or investment decision, Churchill and Company shareholders and other interested persons are advised to read, once available, the preliminary proxy statement/prospectus and any amendments thereto and, once available, the definitive proxy statement/prospectus, as well as other documents filed with the SEC by Churchill in connection with the proposed transaction, as these documents will contain important information about Churchill, the Company and the proposed transaction. Shareholders may obtain a copy of the preliminary or definitive proxy statement/prospectus, once available, as well as other documents filed by Churchill with the SEC, without charge, at the SEC’s website located at www.sec.gov or by directing a written request to Churchill Capital Corp X, 640 Fifth Avenue, 12th Floor, New York, NY 10019.

Forward-Looking Statements

This Current Report on Form 8-K includes “forward-looking statements” within the meaning of the federal securities laws. Forward-looking statements may be identified by the use of words such as “estimate,” “plan,” “project,” “forecast,” “intend,” “will,” “expect,” “anticipate,” “believe,” “seek,” “target,” “continue,” “could,” “may,” “might,” “possible,” “potential,” “predict” or similar expressions that predict or indicate future events or trends or that are not statements of historical matters. We have based these forward-looking statements on current expectations and projections about future events. These statements include: projections of market opportunity and market share; estimates of customer adoption rates and usage patterns; projections regarding the Company’s ability to commercialize new products and technologies; projections of development and commercialization costs and timelines; expectations regarding the Company’s ability to execute its business model and the expected financial benefits of such model; expectations regarding the Company’s ability to attract, retain and expand its customer base; the Company’s deployment of proceeds from capital raising transactions; the Company’s expectations concerning relationships with strategic partners, suppliers, governments, state-funded entities, regulatory bodies and other third parties; the Company’s ability to maintain, protect and enhance its intellectual property; future ventures or investments in companies, products, services or technologies; development of favorable regulations affecting the Company’s markets; the potential benefits of the proposed transaction and expectations related to its terms and timing; and the potential for the Company to increase in value..

These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions, many of which are beyond the control of the Company and Churchill.

- 2 -

These forward-looking statements are subject to known and unknown risks, uncertainties and assumptions that may cause Churchill’s actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by such statements. Such risks and uncertainties include: that the Company is pursuing an emerging technology, faces significant technical challenges and may not achieve commercialization or market acceptance; the Company’s historical net losses and limited operating history; the Company’s expectations regarding future financial performance, capital requirements and unit economics; the Company’s use and reporting of business and operational metrics; the Company’s competitive landscape; the Company’s dependence on members of its senior management and its ability to attract and retain qualified personnel; the Company’s concentration of revenue in contracts with government or state-funded entities; the potential need for additional future financing; the Company’s ability to manage growth and expand its operations; potential future acquisitions or investments in companies, products, services or technologies; the Company’s reliance on strategic partners and other third parties; the Company’s ability to maintain, protect and defend its intellectual property rights; risks associated with privacy, data protection or cybersecurity incidents and related regulations; the use, rate of adoption and regulation of artificial intelligence and machine learning; uncertainty or changes with respect to laws and regulations; uncertainty or changes with respect to taxes, trade conditions and the macroeconomic environment; the combined company’s ability to maintain internal control over financial reporting and operate a public company; the possibility that required regulatory approvals for the proposed transaction are delayed or are not obtained, which could adversely affect the combined company or the expected benefits of the proposed transaction; the risk that shareholders of Churchill could elect to have their shares redeemed, leaving the combined company with insufficient cash to execute its business plans; the occurrence of any event, change or other circumstance that could give rise to the termination of the business combination agreement; the outcome of any legal proceedings or government investigations that may be commenced against the Company or Churchill; failure to realize the anticipated benefits of the proposed transaction; the ability of Churchill or the combined company to issue equity or equity-linked securities in connection with the proposed transaction or in the future; and other factors described in Churchill’s filings with the SEC. Additional information concerning these and other factors that may impact such forward-looking statements can be found in filings and potential filings by the Company, Churchill or the combined company resulting from the proposed transaction with the SEC, including under the heading “Risk Factors.” If any of these risks materialize or assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. In addition, these statements reflect the expectations, plans and forecasts of the Company’s and Churchill’s management as of the date of this Current Report on Form 8-K; subsequent events and developments may cause their assessments to change. While the Company and Churchill may elect to update these forward-looking statements at some point in the future, they specifically disclaim any obligation to do so. Accordingly, undue reliance should not be placed upon these statements.

In addition, statements that “we believe” and similar statements reflect Churchill’s beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this Current Report on Form 8-K, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and Churchill’s statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

An investment in Churchill is not an investment in any of Churchill’s founders’ or sponsors’ past investments, companies or affiliated funds. The historical results of those investments are not indicative of future performance of Churchill, which may differ materially from the performance of Churchill’s founders’ or sponsors’ past investments.

You can find more information about Churchill’s directors and executive officers in Churchill’s final prospectus related to its initial public offering filed with the SEC on May 15, 2025.
