Risk Factors Investing in us involves a high degree of risk. The risks and uncertainties set out below are a summary only and are not the only risks we face. See the section entitled"RiskFactors" in the Registration Statement on Form S-4 filed by Churchill IX with the SEC (as amended), and the prospectus/proxy statement included therein, as well as other information included in the Registration Statement and proxy statement/prospectus for a more detailed discussion of factors that you should consider carefully before making an investment decision. We may face additional risks and uncertainties that are not presently known to us, or that we currently deem immaterial, which may also impair our business or financial condition. • Autonomous driving technology is an emerging technology, and we face significant technical challenges to commercialize our technology. • PlusAI have incurred net losses since our inception, and we expect to incur significant expenses and continuing losses for the foreseeable future. •PlusAI's limited operating history makes it difficult to evaluate its future prospects and the risks and challenges it may encounter, particularly with respect to its nascent HyperFoundry data and tools offerings. •PlusAI's technology may be lesser performing or developing and commercializing and scaling our technology may take us longer to complete than we currently anticipate. • PlusAI operate in an intensely competitive market and some market participants have substantially greater resources. • PlusAI expect to rely on a limited number of customers for a significant portion of its future revenue, particularly with respect to its nascent HyperFoundry data and tools offerings. • It is possible thatPlusAI's model does not materialize as expected, in particular as a result ofPlusAI's software-focused business model and its limited experience with its nascent HyperFoundry data and tools offerings. • Deployment and commercialization may be delayed due to delays inPlusAI's anticipated timeline for completion and validation of acceptable safety testing and measures for our technology and the development of plans for ensuring acceptable driver-out safety, delays in the production, reliability or revision of truck and computer hardware required for our technology from our partners or suppliers.PlusAI's leading global original equipment manufacturers partners and their customers, or the industry more generally, may delay, scale back or deprioritize the necessary investment required for the adoption of our technology or autonomous technology generally. • PlusAI is highly dependent on the services of our senior management team and, specifically, our co-founders. •PlusAI's technology may not function as intended due to flaws or errors inPlusAI's software, hardware, systems or processes, product defects, or human error in administering these systems or processes. • PlusAI is subject to evolving and uncertain regulations, including those governing motor carriers and autonomous vehicles, and unfavorable changes to these regulations or any failure by us to comply with these regulations may adversely affect PlusAI. • PlusAI may be subject to product liability that could result in significant direct or indirect costs, which could materially and adversely affectPlusAI's business, financial condition and results of operations. • PlusAI identified material weaknesses in our internal control over financial reporting in connection with the preparation and audit of our financial statements for the years ended December 31, 2025 and 2024, and we may identify additional material weaknesses in the future that may cause us to fail to meet our reporting obligations or result in material misstatements of our financial statements. If we fail to remediate existing material weaknesses, identify additional material weaknesses or fail to establish and maintain effective internal control over financial reporting, our ability to accurately and timely report our financial results could be adversely affected. • PlusAI may not be able to adequately obtain, maintain, protect, defend or adequately enforce our intellectual property rights or prevent unauthorized parties from copying or reverse engineering its solutions in a cost-effective manner or at all, particularly with respect to its nascent HyperFoundry data and tools offerings. • Third-party claims that we are infringing intellectual property rights, whether successful or not, could subject us to costly and time-consuming litigation or expensive licenses.

Risk Factors • The Sponsor, certain members of the CHURCHILL IX Board and certain CHURCHILL IX officers have interests in the business combination that are different from or are in addition to other shareholders in recommending that shareholders vote in favor of approval of the business combination proposal and approval of the other proposals described in the proxy statement/prospectus. • The estimated net cash per share of CHURCHILL IX Ordinary Shares that will be contributed to the post-closing company in the business combination is less than the redemption price. Accordingly, CHURCHILL IX public shareholders who do not exercise redemption rights will receive shares of post-closing company Class A common stock that may have a value less than the amount they would receive upon exercising their redemption rights. Further, the shares of most companies that have recently completed business combinations between a special purpose acquisition company and an operating company have traded at prices below $10.00 per share. Accordingly, CHURCHILL IX public shareholders who do not exercise their redemption rights may hold shares of post-closing company Class A common stock that never obtain a value equal to or exceeding their per share value of the trust account. • CHURCHILLIX's shareholders will experience dilution as a consequence of, among other transactions, the issuance of post-closing company Class A common stock as consideration in the business combination. Having a minority share position may reduce the influence that CHURCHILLIX's current shareholders will have on the management of the post-closing company. • The deregistration of CHURCHILL IX as an exempted company registered under the laws of the Cayman Islands and registration by way of continuation and domestication of CHURCHILL IX into a Delaware corporation being undertaken in connection with the business combination may result in adverse tax consequences for holders of CHURCHILL IX public shares or CHURCHILL IX Warrants. • CHURCHILL IX and PlusAI have incurred and expect to incur significant costs associated with the business combination. Whether or not the business combination is completed, the incurrence of these costs will reduce the amount of cash available to be used for other corporate purposes by CHURCHILL IX if the business combination is not completed. • Upon the closing of the business combination, the rights of holders of post-closing company Class A common stock arising under the Delaware General Corporate Law will differ from and may be less favorable in certain aspects to the current rights of holders of CHURCHILL IX Ordinary Shares arising under the Companies Act (As Revised) of the Cayman Islands. • A market for the post-closingcompany's securities may not continue, which would adversely affect the liquidity and price of the Post-ClosingCompany's securities. • Following the Closing, the Nasdaq may delist shares of post-closing company Class A common stock from trading on its exchange, which could limitinvestors' ability to transact in our securities and subject us to additional trading restrictions. • If the businesscombination's benefits do not meet the expectations of investors, shareholders or financial analysts, the market price of the post-closingcompany's securities may decline. • We cannot assure you that we will be able to complete the Transactions or another initial business combination by the end of the completion window, in which case CHURCHILL IX will cease all operations except for the purpose of winding up and CHURCHILL IX would redeem the CHURCHILL IX public shares and liquidate, in which case CHURCHILLIX's public shareholders would only receive approximately $10.70 per share (based on amounts in the trust account at December 31, 2025), or less than such amount in certain circumstances. • Because CHURCHILL IX is incorporated under the laws of the Cayman Islands, in the event the business combination is not completed, you may face difficulties in protecting your interests, and your ability to protect your rights through the U.S. federal courts may be limited. • Legal proceedings in connection with the business combination, the outcomes of which are uncertain, could delay or prevent the completion of the business combination. • PlusAI may not be able to reach additional definitive agreements with respect to its HyperFoundry platform beyond the TRATON Agreement, or may reach such agreements on terms less favorable to PlusAI than currently anticipated.
