©2024 Silvaco Group, Inc. 2 Disclaimer This presentation is for informational purposes only and does not constitute an offer to sell, a solicitation of an offer to buy, or a recommendation to purchase any equity, debt or other financial instruments, of Silvaco Group, Inc. ("Silvaco" or the “Company”). The information contained herein does not purport to be all-inclusive. The data contained herein is derived from various internal and external sources. No representation is made as to the reasonableness of the assumptions made or the accuracy or completeness of any projections or modeling or any other information contained herein. Any data on past performance or modeling contained herein is not an indication as to future performance. Silvaco assumes no obligation to update any information in this presentation, except as required by law. This presentation and the accompanying oral presentation include express and implied “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. In some cases, you can identify forward-looking statements by terms such as “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “project,” “will,” “would,"” “should,” “could,” “can,” “predict,” “potential,” “target,” “explore,” “continue,” or the negative of these terms, and similar expressions intended to identify forward-looking statements. However, not all forward-looking statements contain these identifying words. These statements may relate to our market size and growth strategy, our estimated and projected costs, margins, revenue, expenditures and growth rates, our future results of operations or financial condition, our plans and objectives for future operations, growth, initiatives, or strategies. By their nature, these statements are subject to numerous uncertainties and risks, including factors beyond our control, that could cause actual results, performance or achievement to differ materially and adversely from those anticipated or implied in the statements. These assumptions, uncertainties and risks include, among others, risks related to market conditions and global economic factors (including the potential adverse effects of the ongoing global COVID-19 pandemic and the ongoing conflicts between Russia and Ukraine), and Israel and Hamas our ability to access debt and equity financing, our efforts to establish and maintain proper and effective internal controls, and other factors relating to our business, operations and financial performance. It is not possible for us to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results or outcomes to differ materially from those contained in any forward-looking statements we may make. You should not rely upon forward-looking statements as predictions of future events. Although our management believes that the expectations reflected in our statements are reasonable, we cannot guarantee that the future results, levels of activity, performance or events and circumstances described in the forward-looking statements will be achieved or occur. Moreover, neither we, nor any other person, assumes responsibility for the accuracy and completeness of these statements. Recipients are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date such statements are made and should not be construed as statements of fact. Except to the extent required by federal securities laws, we undertake no obligation to update any information or any forward-looking statements as a result of new information, subsequent events, or any other circumstances after the date hereof, or to reflect the occurrence of unanticipated events. This presentation and the accompanying oral presentation also contain estimates and other statistical data made by independent parties and by us relating to market size and growth and other data about our industry. This data involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. In addition, projections, assumptions, and estimates of our future performance and the future performance of the markets in which we compete are necessarily subject to a high degree of uncertainty and risk. This presentation contains unaudited financial information. The unaudited financial information has been prepared on the same basis as the Company's audited financial statements and, in the opinion of management, reflects all adjustments necessary for the fair presentation of the unaudited financial information. However, the unaudited financial information contained in this presentation is preliminary and may be subject to change. Accordingly, such financial information may be adjusted or may be presented differently in periodic reports or other filings filed by the Company with the Securities and Exchange Commission, and such differences may be material. In addition, past performance is not a guarantee or indication of future financial condition and/or results of operations and should not be relied upon for such reason. In addition to the financials presented in accordance with U.S. generally accepted accounting principles (“GAAP”), this presentation includes non-GAAP operating income (loss). Non-GAAP metrics have limitations as analytical tools and you should not consider them in isolation or as a substitute for or superior to the most directly comparable financial measures prepared in accordance with U.S. GAAP. There are a number of limitations related to the use of non-GAAP metrics versus their nearest GAAP equivalents. Other companies, including companies in our industry, may calculate non-GAAP metrics differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP metrics as tools for comparison. We urge you to review the reconciliation of Silvaco's non-GAAP metrics to the most directly comparable GAAP financial measures, and not to rely on any single financial measure to evaluate our business. See the Appendix for reconciliation between each non-GAAP metric and the most comparable GAAP measure. Silvaco and the Silvaco logo are trademarks of Silvaco Group, Inc.
