Certain statements included in this document are not historical facts but are forward-looking statements. All statements other than statements of historical facts contained in this document are forward-looking statements. Any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are also forward-looking statements. In some cases, you can identify forward-looking statements by words such as “estimate,” “plan,” “project,” “forecast,” “intend,” “expect,” “anticipate,” “believe,” “seek,” “strategy,” “future,” “opportunity,” “may,” “target,” “should,” “will,” “would,” “will be,” “will continue,” “will likely result,” “preliminary,” or similar expressions that predict or indicate future events or trends or that are not statements of historical matters, but the absence of these words does not mean that a statement is not forward-looking. Forward-looking statements include, without limitation, SVAC’s, General Fusion’s, or their respective management teams’ expectations concerning the Proposed Business Combination and expected benefits or timing thereof; the outlook for General Fusion’s business, including its ability to commercialize MTF or any other fusion technology on its expected timeline or at all; statements regarding the current and expected results of General Fusion’s LM26 program; the ability to execute General Fusion’s strategies, including on any expected timeline or anticipated cost basis; projected and estimated financial performance; anticipated industry trends; future capital expenditures; government regulation of fusion energy; and environmental risks; as well as any information concerning possible or assumed future results of operations of General Fusion. The forward-looking statements are based on the current expectations of the respective management teams of SVAC and General Fusion, as applicable, and are inherently subject to uncertainties and changes in circumstance and their potential effects. There can be no assurance that future developments will be those that have been anticipated. These forward-looking statements involve a number of risks, uncertainties or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to, (i) the risk that the Proposed Business Combination may not be completed in a timely manner or at all, which may adversely affect the price of SVAC’s securities; (ii) the failure to satisfy the conditions to the consummation of the Proposed Business Combination, including the adoption of the Business Combination Agreement by the shareholders of SVAC and General Fusion and the receipt of regulatory approvals; (iii) market risks; (iv) the occurrence of any event, change or other circumstance that could give rise to the termination of the Business Combination Agreement; (v) the effect of the announcement or pendency of the Proposed Business Combination on General Fusion’s business relationships, performance, and business generally; (vi) risks that the Proposed Business Combination disrupts current plans of General Fusion and potential difficulties in its employee retention as a result of the Proposed Business Combination; (vii) the outcome of any legal proceedings that may be instituted against General Fusion or SVAC related to the Business Combination Agreement or the Proposed Business Combination; (viii) failure to realize the anticipated benefits of the Proposed Business Combination; (ix) the inability to maintain the listing of SVAC’s securities or to meet listing requirements and maintain the listing of the combined company’s securities on Nasdaq; (x) the risk that the Proposed Business Combination may not be completed by SVAC’s business combination deadline and the potential failure to obtain an extension of the business combination deadline if sought by SVAC; (xi) the risk that the price of the combined company’s securities may be volatile due to a variety of factors, including changes in laws, regulations, technologies, natural disasters, national security tensions, and macro-economic and social environments affecting its business; (xii) laws and regulations governing General Fusion’s research and development activities, and changes in such laws and regulations; (xiii) any failure to commercialize MTF on the expected timeline or at all, including any failure to achieve the objectives of the LM26 program; (xiv) environmental regulations and legislation; (xv) the effects of climate change, extreme weather events, water scarcity, and seismic events, and the effectiveness of strategies to deal with these issues; (xvi) fluctuations in currency markets; (xvii) General Fusion’s ability to complete and successfully integrate any future acquisitions; (xviii) increased competition in the fusion industry; (xix) limited supply of materials and supply chain disruptions; and (xx) the risk that the proposed private placement of convertible preferred shares and warrants by General Fusion (the “PIPE Financing”) may not be completed, or that other capital needed by the combined company may not be raised on favorable terms, or at all, including as a result of the restrictions agreed to in connection with the PIPE Financing. The foregoing list is not exhaustive, and there may be additional risks that neither SVAC nor General Fusion presently know or that SVAC and General Fusion currently believe are immaterial. You should carefully consider the foregoing factors, any other factors discussed in this document and the other risks and uncertainties described in the “Risk Factors” section of the Final Prospectus and the risks described in the Registration Statement, or to be described in any amendment or supplement thereto; the risks described in the definitive proxy statement/prospectus filed with the SEC on June 12, 2026, or to be described in any amendment or supplement thereto; and those discussed and identified in filings made with the SEC by SVAC from time to time. General Fusion and SVAC caution you against placing undue reliance on forward-looking statements, which reflect current beliefs and are based on information currently available as of the date a forward-looking statement is made. Forward-looking statements set forth in this document speak only as of the date of this document. Neither General Fusion nor SVAC undertakes any obligation to revise forward-looking statements to reflect future events, changes in circumstances, or changes in beliefs. In the event that any forward-looking statement is updated, no inference should be made that General Fusion or SVAC will make additional updates with respect to that statement, related matters, or any other forward-looking statements. Any corrections or revisions and other important assumptions and factors that could cause actual results to differ materially from forward-looking statements, including discussions of significant risk factors, may appear, up to the consummation of the Proposed Business Combination, in SVAC’s public filings with the SEC, which are or will be (as applicable) accessible at www.sec.gov, and which you are advised to review carefully.
