Exhibit 99.1

Churchill Capital Corp X Shareholders Approve Business Combination with Infleqtion

Nearly 100% of trust cash retained ahead of closing

Over $550 million of gross proceeds to be delivered to Infleqtion

Transaction expected to close February 13, 2026

NEW YORK – February 12, 2026 – Churchill Capital Corp X (“Churchill X”) (NASDAQ: CCCX), a publicly traded special purpose acquisition company, today announced that its shareholders have approved the previously announced business combination with Infleqtion, Inc. (“Infleqtion”), a global leader in quantum sensing and quantum computing powered by neutral-atom technology.

At a special meeting held today, the business combination and all related proposals were approved with overwhelming support from Churchill X shareholders, with over 90% of votes cast at the meeting voting in favor of the business combination (the “Transaction”).

The strong support from Churchill X’s shareholders is expected to result in Infleqtion receiving over $550 million of gross proceeds (the “Churchill X Proceeds”), including nearly 100% of the cash held in Churchill X’s trust account prior to the redemption deadline and more than $125 million of incremental capital raised through a common stock PIPE at the transaction valuation from leading existing Infleqtion stockholders and new institutional investors.

Infleqtion expects to be well capitalized at closing, combining the Churchill X Proceeds with existing cash on hand to support continued execution. The strengthened balance sheet is expected to accelerate Infleqtion’s technology roadmap and product commercialization, expanding deployments across artificial intelligence, national security, and space while enabling additional real-world applications.

Upon closing of the Transaction, Infleqtion will become the first publicly listed neutral-atom quantum technology company and the only public company with commercial leadership across both quantum computing and precision sensing.

Based on the approval of the domestication proposal by Churchill X’s shareholders, Churchill X will effect a deregistration, pursuant to which Churchill’s jurisdiction of incorporation will change from

the Cayman Islands to the State of Delaware. Effective upon the domestication, the continuing entity will be renamed “Infleqtion, Inc.” and existing shareholders of Churchill will hold shares in Infleqtion, Inc. rather than in a Cayman Islands company.

Churchill X, whose shares of common stock, warrants and units are currently listed on The Nasdaq Stock Market LLC (“Nasdaq”), will delist from Nasdaq. Shares of common stock and warrants of the post-combination company, Infleqtion, Inc., will be listed on the New York Stock Exchange (“NYSE”) beginning on February 17, 2026, under the ticker symbols “INFQ” and “INFQ WS”, respectively. Prior to the closing of the Transaction, each of the units sold by Churchill X in its initial public offering will be separated into one Class A ordinary share and one-quarter of one warrant of Churchill X and will no longer be listed on Nasdaq following the closing of the Transaction. The NYSE listing and Nasdaq delisting are subject to the closing of the Transaction and fulfillment of all NYSE listing requirements.

The closing is expected to occur on February 13, 2026, subject to satisfaction of customary closing conditions.
