Disclaimers and Forward-Looking Statements This presentation contains forward-looking statements. All statements other than statements of historical fact contained in this presentation and the related webcast are forward-looking statements, including but not limited to: statements regarding Infleqtion, Inc.’s (“Infleqtion” or the “Company”) commercial opportunities; the Company’s quantum computing and sensing product roadmap, including targets for logical qubit count, physical qubit count, and gate performance; the Company’s projections of market opportunity and market share; estimates of customer adoption rates and usage patterns; projections regarding the Company’s ability to commercialize its products and technologies; the expected benefits of the Company’s relationships with strategic partners, governments, state-funded entities, and government entities, including potential task order awards under indefinite delivery/indefinite quantity contract vehicles and the amount, availability and timing of the proposed U.S. Department of Commerce funding and the satisfaction of conditions to definitive agreements and government approvals; the potential financial benefits from the U.S. Department of Commerce funding; and the potential for the Company to increase in value. In some cases, you can identify forward-looking statements by terms such as “anticipate,” “expect,” “project,” “intend,” “believe,” “may,” “will,” “should,” “plan,” “could,” “continue,” “target,” “contemplate,” “estimate,” “forecast,” “guidance,” “predict,” “possible,” “potential,” “pursue,” “likely,” “on track,” and words and terms of similar substance used in connection with any discussion of future plans, actions, or events. You should not rely upon forward-looking statements as predictions of future events. We have based the forward-looking statements in this presentation largely on our current expectations and projections about future events and trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives, and financial needs, but the forward-looking statements are subject to known and unknown risks uncertainties, assumptions, and other factors that may cause actual results or outcomes to be materially different from any future results or outcomes expressed or implied by the forward-looking statements. These risks, uncertainties, assumptions, and other factors include, but are not limited to, our ability to grow and manage growth profitably; our financial and business performance; changes in our strategy, future operations, financial position, prospects and plans; the implementation, market acceptance and success of our business model, growth strategy and opportunities, and our ability to commercialize our quantum computing technology; our expectations with respect to market opportunity and market growth; the expected benefits of and ability to maintain and enter into new contracts, awards and other relationships, partnerships or collaborations with governments and government entities; our ability to maintain our NYSE listing; the potential for our quantum computing technology to achieve quantum advantage; the ability of our products to meet government counterparties’ and customers’ technical requirements and compliance and regulatory needs; our ability to achieve timing and product development milestones on our product roadmap; our ability to attract and retain qualified employees and management; our expectations regarding our ability to obtain and maintain intellectual property protection and not infringe on the rights of others; expectations regarding the time during which we will be an emerging growth company under the Jumpstart Our Business Startups Act of 2012, as amended; our future capital requirements and sources and uses of cash; our ability to obtain funding for our operations and future growth; and the outcome of any known and unknown litigation and regulatory proceedings. The forward-looking statements contained in this presentation are also subject to additional risks, uncertainties, and factors, including those more fully described in the Company’s filings with the Securities and Exchange Commission (the “SEC”), including its most recently filed Annual Report on Form 10-K and subsequent filings with the SEC.
