Forward-looking statements may be identified by the use of words such as “estimate,” “plan,” “project,” “forecast,” “intend,” “will,” “expect,” “anticipate,” “believe,” “seek,” “target” or other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These statements are based on various assumptions, whether or not identified in this Current Report, and on the current expectations of EigenQ’s and SVAQ’s management and are not predictions of actual performance.

These forward-looking statements are provided for illustrative purposes only and are not intended to serve as and must not be relied on by any investor 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 actual events and circumstances are beyond the control of EigenQ and SVAQ. These forward-looking statements are subject to a number of risks and uncertainties, including (1) the occurrence of any event, change or other circumstances that could give rise to the termination of the proposed Business Combination; (2) the outcome of any legal proceedings that may be instituted against EigenQ or SVAQ, the combined company or others following the announcement of the proposed Business Combination; (3) the inability to complete the proposed Business Combination due to the failure to obtain approval of the shareholders of EigenQ or SVAQ or to satisfy other conditions to closing; (4) changes to the proposed structure of the proposed Business Combination that may be required or appropriate as a result of applicable laws or regulations or as a condition to obtaining regulatory approval of the proposed Business Combination; (5) the ability to meet stock exchange listing standards following the consummation of the proposed Business Combination; (6) the risk that the proposed Business Combination disrupts current plans and operations of EigenQ as a result of the announcement and consummation of the proposed Business Combination; (7) EigenQ’s ability to scale and grow its business, and the ability to recognize the anticipated benefits of the proposed Business Combination, which may be affected by, among other things, competition and the ability of the combined company to grow and manage growth profitably, maintain relationships with customers and retain its management and key employees; (8) the ability to implement business plans, forecasts, identify and realize additional opportunities, and other expectations; (9) political, social or economic instability in the emerging markets, including the Middle East, and other countries in which EigenQ, the post-combination company, relevant OEMs and other channel participants and customers of some or all of the foregoing operate or plan to operate; (10) risks relating to product development and commercialization timing, OEM integration, customer adoption and strategic partnerships; (11) EigenQ’s ability to maintain and recognize benefits from its existing strategic relationships; (12) costs related to the proposed Business Combination; (13) changes in applicable laws or regulations; (14) changes in government mandates, requirements and standards as they relate to quantum security and infrastructure; (15) EigenQ’s estimates of expenses and profitability and underlying assumptions with respect to shareholder redemptions and purchase price and other adjustments; (16) any downturn or volatility in economic conditions; (17) changes in the competitive environment affecting EigenQ or its customers, including EigenQ’s inability to introduce new products or technologies; (18) the impact of pricing pressure and erosion; (19) supply chain risks; (20) risks to EigenQ’s ability to protect its intellectual property and avoid infringement by others, or claims of infringement against EigenQ; (21) the possibility that EigenQ or SVAQ may be adversely affected by other economic, business and/or competitive factors; (22) EigenQ’s estimates of its financial performance; (23) risks related to the fact that SVAQ is incorporated in the Cayman Islands and governed by Cayman Islands law; and those factors discussed in SVAQ’s Annual Report on Form 10-K for the period ended December 31, 2025, and Quarterly Report on Form 10-Q for the quarter ended March 31, 2026, in each case, under the heading “Risk Factors,” and subsequent Quarterly Reports on Form 10-Q, the Registration Statement and proxy statement/prospectus, or other documents that will be filed with the SEC. If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that neither EigenQ nor SVAQ presently knows or that EigenQ and SVAQ currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect EigenQ’s and SVAQ’s expectations, plans or forecasts of future events and views as of the date of this Current Report. EigenQ and SVAQ anticipate that subsequent events and developments will cause EigenQ’s and SVAQ’s assessments to change. However, while EigenQ and SVAQ may elect to update these forward-looking statements at some point in the future, EigenQ and SVAQ specifically disclaim any obligation to do so. These forward-looking statements should not be relied upon as representing EigenQ’s and SVAQ’s assessments as of any date after the date of this Current Report. Accordingly, undue reliance should not be placed upon the forward-looking statements.
