Churchill Capital Corp IX, a special purpose acquisition company (SPAC) listed on NASDAQ under the ticker CCIX, has announced the postponement of its extraordinary general meeting of shareholders. The meeting, originally scheduled for February 3, 2026, has been rescheduled to February 11, 2026, at 9:00 a.m. Eastern Time. The event will take place in person at Willkie Farr & Gallagher LLP’s offices in New York and will also be available via live webcast at https://www.cstproxy.com/churchillcapitalx/2026. The delay was made by the Board of Directors to allow additional time for engagement with shareholders, particularly following PlusAI’s recent announcement of an expanded partnership with TRATON Group. This update was filed by Churchill IX in a Current Report on Form 8-K on January 26, 2026. As a result of the rescheduling, the deadline for public shareholders to submit redemption requests has been extended from January 30, 2026, to 5:00 p.m. Eastern Time on February 9, 2026—the second business day before the new meeting date. Shareholders who have already submitted redemption requests may revoke them before the new deadline by following the procedures outlined in the proxy statement/prospectus, available at http://www.sec.gov. All shareholders of record as of the close of business on January 7, 2026, are eligible to vote at the postponed meeting. Churchill IX encourages all shareholders to submit their proxies promptly, whether online or by mail, regardless of the number of shares held. Valid proxies previously submitted remain valid for the rescheduled meeting. For voting assistance, shareholders can contact Sodali & Co, Churchill IX’s proxy solicitor, at (800) 662-5200 (toll-free) or (203) 658-9400 (for banks and brokers), or email [email protected]. Additional information about the proposed business combination and the matters to be voted on can be found in the proxy statement/prospectus on the SEC’s website. Churchill IX’s board recommends that shareholders vote in favor of the proposed business combination with Plus Automation, Inc. (PlusAI), a leader in AI-powered software for autonomous trucks. If all conditions are met, including shareholder approval, the combined company plans to list its common stock and public warrants on Nasdaq under the symbols “PLS” and “PLSW,” respectively, subject to Nasdaq’s listing requirements and the closing of the transaction. PlusAI, headquartered in Silicon Valley with operations in the U.S. and Europe, has partnered with major industry players including TRATON Group, Hyundai, Iveco, NVIDIA, Bosch, DSV, and Goodyear. The company was recognized by Fast Company as one of the World’s Most Innovative Companies.
