These forward-looking statements are based upon current estimates and assumptions that, while considered reasonable by IQM and its management, and RAAQ and its management, as the case may be, are inherently uncertain. These statements include: projections of market opportunity and market share; estimates of customer adoption rates and usage patterns; projections regarding IQM's ability to commercialize new products and technologies; projections of development and commercialization costs and timelines; expectations regarding IQM's ability to execute its business model and the expected financial benefits of such model; expectations regarding IQM's ability to attract, retain and expand its customer base; IQM's deployment of proceeds from capital raising transactions; IQM's expectations concerning relationships with strategic partners, suppliers, governments, state-funded entities, regulatory bodies and other third parties; IQM's ability to maintain, protect and enhance its intellectual property; future ventures or investments in companies, products, services or technologies; development of favorable regulations affecting IQM's markets; the successful consummation and potential benefits of the proposed Business Combination and expectations related to its terms and timing; the stock exchanges on which the securities of the combined company are expected to trade; proceeds from the Business Combination and related PIPE; funds received by the combined company from RAAQ's trust account and redemptions by RAAQ's public shareholders; IQM's ability to commercialize its hardware and software; the expectation that IQM is building the sovereign infrastructure that allows quantum ecosystems to grow; and the potential for IQM to increase in value.

These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions, many of which are beyond the control of IQM and RAAQ.

These forward-looking statements are subject to known and unknown risks, uncertainties and assumptions that may cause the actual results of the combined company following the proposed Business Combination, 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 IQM is pursuing an emerging technology, which faces significant technical challenges and may not achieve commercialization or market acceptance; IQM's historical net losses and limited operating history; IQM's expectations regarding future financial performance, capital requirements and unit economics; IQM's use and reporting of business and operational metrics; IQM's competitive landscape; IQM's dependence on members of its senior management and its ability to attract and retain qualified personnel; the potential need for additional future financing; IQM's concentration of revenue in contracts with government or state-funded entities; IQM's ability to manage growth and expand its operations; potential future acquisitions or investments in companies, products, services or technologies; IQM's reliance on strategic partners and other third parties; IQM'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, rate of adoption 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 possibility that required regulatory approvals for the proposed Business Combination are delayed or are not obtained, which could adversely affect the combined company or the expected benefits of the proposed Business Combination; the risk that shareholders of RAAQ 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 IQM or RAAQ; failure to realize the anticipated benefits of the proposed Business Combination; the ability of IQM or the combined company to issue equity or equity-linked securities in connection with the proposed Business Combination or in the future; and other factors described in the Registration Statement and RAAQ's and IQM's other filings with the SEC. These forward-looking statements are based on certain assumptions, including that none of the risks identified above materialize; that there are no unforeseen changes to economic and market conditions, and that no significant events occur outside the ordinary course of business. Additional information concerning these and other factors that may impact such forward-looking statements can be found in filings and potential filings by IQM, RAAQ or the combined company resulting from the proposed Business Combination with the SEC, including under the heading "Risk Factors." If any of these risks materialize or assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. In addition, these statements reflect the expectations, plans and forecasts of IQM's and RAAQ's management as of the date of this communication; subsequent events and developments may cause their assessments to change. While IQM and RAAQ may elect to update these forward-looking statements at some point in the future, they specifically disclaim any obligation to do so, unless required by applicable securities laws. Accordingly, undue reliance should not be placed upon these statements.

In addition, statements that "we believe" and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this communication, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information.
