Silvaco Group, Inc. (Nasdaq: SVCO) Financial Supplement Key Takeaways • Acquired 9 new customers across key markets including AI infrastructure (Power, Memory, Foundry) Photonics, and IoT markets, which represented approximately 23% of gross bookings for the quarter. We also expanded opportunities with existing customers, which accounted for 38% of gross bookings. • Gained momentum with Power, Photonics, and Advanced CMOS customers as they expand adoption of the FTCO platform for their next-generation product development. We announced that Excelliance MOS adopted Silvaco DTCO Flow for next generation silicon carbide devices and our partnership with Korean Kyung Hee University’s Professor Jin Jang on FTCO for next generation display technologies. • Expanded SAM by an estimated $600 million with the acquisitions of Cadence’s PPC product line and Tech-X Corporation. • Faraday Technology selected Silvaco FlexCAN IP for advanced automotive ASIC design. • ProMOS adopted our Victory TCAD solution for the development of next generation silicon photonics devices. • On April 29, 2025, Silvaco closed the acquisition of Tech-X Corporation, expanding our product offerings into wafer-level and photonics digital twin modeling. • Beginning with this quarter, we will be providing a new performance metric called Annual Contract Value, or ACV. We believe that ACV will be a more meaningful metric for measuring the underlying performance and health of the business. In particular ACV lowers the impact of quarterly volatility in revenue that results from ASC 606 revenue accounting rules.

Note 1: As of May 7, 2025, Silvaco is providing updated guidance for its second quarter of 2025 and its full-year 2025, which represents Silvaco’s current estimates on its operations and financial results. The financial information below represents forward-looking financial information and in some instances forward-looking, non-GAAP financial information, including estimates of non-GAAP gross margin, non-GAAP operating income (loss) and non-GAAP diluted net income (loss) per share. GAAP gross margin is the most comparable GAAP measure to non-GAAP gross margin and GAAP operating income (loss) is the most comparable GAAP measure to non-GAAP operating income (loss). GAAP diluted net income (loss) per share is the most comparable GAAP measure to non-GAAP diluted net income (loss) per share. Non-GAAP gross margin differs from GAAP gross margin in that it excludes items such as stock-based compensation expense, amortization of acquired intangible assets, and acquisition-related professional fees and retention bonuses. Non- GAAP operating income (loss) differs from GAAP operating income (loss) in that it excludes items such as acquisition-related estimated litigation claim and legal costs, stock-based compensation expense, amortization of acquired intangible assets, acquisition-related professional fees and retention bonuses, and IPO preparation costs. Non-GAAP diluted net income (loss) per share differs from GAAP diluted net income (loss) per share in that it excludes certain costs, including IPO preparation costs, acquisition-related estimated litigation claim and legal costs, stock-based compensation expense, amortization of acquired intangible assets, acquisition-related professional fees and retention bonuses, change in fair value of contingent consideration, foreign exchange (gain) loss, and the income tax effect on non-GAAP items. Silvaco is unable to predict with reasonable certainty the ultimate outcome of these exclusions without unreasonable effort. Therefore, Silvaco has not provided guidance for GAAP gross margin, GAAP operating income or GAAP diluted net income (loss) per share or a reconciliation of the forward-looking non-GAAP gross margin or non-GAAP operating income or non-GAAP diluted net income (loss) per share guidance to GAAP gross margin or GAAP operating income or GAAP diluted net income (loss) per share, respectively. However, it is important to note that these excluded items could be material to our results computed in accordance with GAAP in future periods. x Silvaco Group, Inc. Financial Results 1

Silvaco Group, Inc. (Nasdaq: SVCO) Appendix I - Reconciliation of GAAP to Non-GAAP Financials Measures ($ in '000s, except Per Share Data) Discussion of Non-GAAP Financial Measures We use certain non-GAAP financial measures to supplement the performance measures in our consolidated financial statements, which are presented in accordance with GAAP. These non-GAAP financial measures include non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating income (loss), non-GAAP net income (loss), and non-GAAP net income (loss) per share. We use these non-GAAP financial measures for financial and operational decision-making and as a means to assist us in evaluating period-to-period comparisons. We define non-GAAP gross profit and non-GAAP gross margin as our GAAP gross profit and GAAP gross margin adjusted to exclude certain costs, including stock-based compensation expense, amortization of acquired intangible assets, payroll tax from the IPO lock-up release, and acquisition-related professional fees and retention bonuses. We define non-GAAP operating income (loss), as our GAAP operating income (loss) adjusted to exclude certain costs, including IPO preparation costs, acquisition-related estimated litigation claim and legal costs, stock-based compensation expense, amortization of acquired intangible assets, impairment charges, payroll tax from the IPO lock-up release, executive severance costs, and acquisition-related professional fees and retention bonuses. We define non-GAAP net income (loss) as our GAAP net income (loss) adjusted to exclude certain costs, including IPO preparation costs, acquisition-related estimated litigation claim and legal costs, stock-based compensation expense, amortization of acquired intangible assets, impairment charges, payroll tax from the IPO lock-up release, executive severance costs, acquisition-related professional fees and retention bonuses, change in fair value of contingent consideration, foreign exchange (gain) loss, loss on debt extinguishment, and the income tax effect on non-GAAP items. Our non-GAAP diluted net income (loss) per share is calculated in the same way as our non-GAAP net income (loss), but on a per share basis. We monitor non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating income (loss), non-GAAP net income (loss) and non-GAAP diluted net income (loss) per share as non-GAAP financial measures to supplement the financial information we present in accordance with GAAP to provide investors with additional information regarding our financial results. Certain items are excluded from our non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating income (loss), non-GAAP net income (loss) and non-GAAP diluted net income (loss) per share because these items are non-cash in nature or are not indicative of our core operating performance and render comparisons with prior periods and competitors less meaningful. We adjust GAAP gross profit, GAAP gross margin, GAAP operating income (loss), and GAAP net income (loss) for these items to arrive at non-GAAP gross profit, non- GAAP gross margin, non-GAAP operating income (loss), and non-GAAP net income (loss) because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structure and the method by which the assets were acquired. By excluding certain items that may not be indicative of our recurring core operating results, we believe that non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating income (loss), non-GAAP net income (loss) and non- GAAP diluted net income (loss) per share provide meaningful supplemental information regarding our performance. We believe these non-GAAP financial measures are useful to investors and others because they allow for additional information with respect to financial measures used by management in its financial and operational decision-making and they may be used by our institutional investors and the analyst community to help them analyze our financial performance and the health of our business. However, there are a number of limitations related to the use of non-GAAP financial measures, and these non-GAAP measures should be considered in addition to, not as a substitute for or in isolation from, our financial results prepared in accordance with GAAP. Other companies, including companies in our industry, may calculate these non-GAAP financial measures differently or not at all, which reduces their usefulness as comparative measures. x Silvaco Group, Inc.

Note 2: On April 29, 2024, the Company effected a 1-for-2 reverse split of its common stock. All of the outstanding equity amounts have been adjusted, on a retroactive basis, to reflect this 1-for-2 reverse stock split for all periods presented. On May 13, 2024, the Company completed the sale of an aggregate of 6,000,000 shares of Common Stock to the public in the IPO. Note 3: The non-GAAP measures presented should not be considered a substitute for the financial results and measures determined or calculated in accordance with GAAP. See Appendix I for more information and a reconciliation of GAAP to Non-GAAP Financials Measures. As a result, the total of the reconciling items may not mathematically foot to the difference between GAAP and Non-GAAP EPS due to differences in share count treatment. Note 4: GAAP EPS is calculated using either basic or diluted weighted-average shares outstanding, depending on whether GAAP net income or loss was reported for the respective period. Non-GAAP EPS is calculated using diluted weighted-average shares outstanding when Non-GAAP net income is reported. Accordingly, reconciling items are presented on a per-share basis using diluted shares when applicable. Silvaco Group, Inc. Financial Results 9
