Cautionary Note Regarding Forward-Looking Statements

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, SVIII’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 SVIII 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 SVIII’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 SVIII 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 SVIII 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 SVIII’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 SVIII’s

business combination deadline and the potential failure to obtain an extension of the business combination deadline if sought by SVIII;

(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 SVIII nor General Fusion presently know or that SVIII 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 SVIII

from time to time. General Fusion and SVIII 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 SVIII 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 SVIII 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 SVIII’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.
