Actual events and circumstances are difficult or impossible to predict and will differ from assumptions, many of which are beyond the control of PlusAI and Churchill.

These forward-looking statements are subject to known and unknown risks, uncertainties and assumptions that may cause our 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 PlusAI is pursuing an emerging technology, faces significant technical challenges and may not achieve commercialization or market acceptance; PlusAI’s historical net losses and limited operating history; PlusAI’s expectations regarding future financial performance, capital requirements and unit economics; PlusAI’s use and reporting of business and operational metrics; PlusAI’s competitive landscape; PlusAI’s dependence on members of its senior management and its ability to attract and retain qualified personnel; the capital requirements of PlusAI’s business plans and the potential need for additional future financing; PlusAI’s ability to manage growth and expand its operations; potential future acquisitions or investments in companies, products, services or technologies; PlusAI’s reliance on strategic partners and other third parties; PlusAI’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 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 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 PlusAI 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
