Forward-Looking Statements This presentation ("Presentation") and any oral statements made in connection with the Presentation do not constitute an offer to sell or a solicitation of an offer to buy any securities. Certain statements in this Presentation may constitute "forward-looking statements" within the meaning of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements include statements regarding the expectations, hopes, beliefs, intentions or strategies of NuScale Power Corporation (the "Company") regarding the future, including, without limitation, statements regarding plans for research and development programs and expectations regarding revenues and profitability. In addition, any statements regarding projections, forecasts, or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. Words such as "anticipate," "believe," "continue," "could," "estimate," "expect," "intend," "may," "might," "plan," "possible," "potential,” “predict," "project," "should," "strive," "would" and similar expressions may identify forward-looking statements, but the absence of these words does not mean that statement is not forward looking. Forward-looking statements are based on current expectations and assumptions that, while considered reasonable by the Company and its management, are inherently uncertain. New risks and uncertainties may emerge from time to time, and it is not possible to predict all risks and uncertainties. Factors that may cause actual results to differ materially from current expectations include, but are not limited to, general economic conditions and other risks, uncertainties and factors (a) set forth in the section entitled "Cautionary Statement Regarding Forward-Looking Statements and Risk Factors"" in the Company's annual report on Form 10-K for the period ended December 31, 2023, the Form S-1 filed on March 20, 2023 and declared effective on March 23, 2023, the Registration Statement on Form S-3 filed on June 1, 2023 and declared effective on June 5, 2023, and under similar headings in subsequent filings with the SEC, and (b) associated with companies like the Company that operate in the energy industry. Such differences may result both from actions within the control of the Company, such as capital investments, asset acquisitions, and marketing initiatives, and from actions outside the control of the Company, such as the demand for the Company's products, changes in technology, competition and general economic and market conditions.
