Silvaco Group, Inc. (Nasdaq: SVCO) Financial Supplement Q3'24 Outlook (See Note 1) Based on current business trends and conditions, the company expects for second quarter 2024 the following: • Gross bookings in the range of $16.0 million to $18.0 million, which would represent a 28% to 44% increase from the third quarter of 2023. • Revenue in the range of $15.5 million to $16.5 million, which would represent a 4% to 10% increase from the third quarter of 2023. • Non-GAAP gross margin in the range of 85% to 88% • Non-GAAP operating income in the range of $1.8 million to $2.8 million, which would represent a 34% decerease to 2% increase from the third quarter of 2023. FY 2024 Outlook (See Note 1) For full year 2024, the Company expects: • Gross bookings in the range of $67.0 million to $71.0 million, which would represent an 15% to 22% increase from 2023. • Revenue in the range of $63.0 million to $66.0 million, which would represent a 16% to 22% increase from 2023. • Non-GAAP gross margin in the range of 85% to 89%. • Non-GAAP operating income in the range of $8.0 million to $11.0 million, which would represent an 82% to 150% increase from 2023. Note 1: As of August 7, 2024, Silvaco is providing guidance for its third quarter of 2024 and its full-year 2024, which represents Silvaco's current estimates on its operations and financial results. The financial information presented represents forward-looking financial information and, in some instances forward-looking, non-GAAP financial information, including estimates of non-GAAP gross margin and non-GAAP operating income. GAAP gross margin is the most comparable GAAP measure to non-GAAP gross margin, and GAAP operating income is the most comparable GAAP measure to non-GAAP operating income. Non-GAAP operating income differs from GAAP operating income in that it excludes items such as certain transaction-related costs, IPO preparation costs, acquisition-related litigation costs, stock-based compensation, amortization of acquired intangible assets, impairment charges and executive severance costs. 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 or GAAP operating income or a reconciliation of the forward-looking non-GAAP gross margin or non-GAAP operating income guidance to GAAP gross margin or GAAP operating income, 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 Key Takeaways • Q2'24 gross bookings of $19.5 million, above the high end of our previoius guidance, up 36% YoY. • Q2'24 revenue of $15.0 million, at the high end of our previous guidance, up 19% year-over-year. • Raising FY 2024 gross bookings outlook and maintaining FY 2024 revenue outlook. • Q2'24 Non-GAAP gross margin of 86%, at the midpoint of our guidance, compared to 81% in Q2 2023. • Initial public offering completed in May raising $106 million, net of underwriters fees. Q2'24 Other Financial Highlights • Revenue by Product Line - - TCAD revenue of $10.4 million, 69% of sales, up 34% YoY - EDA revenue of $3.0 million, 20% of sales, up 20% YoY - SIP revenue of $1.6 million, 11% of sales, down 30% YoY • GAAP gross profit and gross margin of $10.1 million and 68%, compared to $10.2 million and 81%, respectively in Q2 2023. Q2'24 cost of revenues includes stock- based compensation of $2.5 million. • GAAP operating loss and operating margin of ($37.8) million and (253%), compared to ($0.2) million and (2%), respectively in Q2 2023 . Q2'24 includes stock-based compensation of $21.8 million and acquistion related estimated litigation claims cost of $14.7 million. • Non-GAAP operating income and non-GAAP operating margin of $1.7 million and 11%, compared to $0.8million and 6% in Q2 2023, respectively. • GAAP net loss of $38.4 million, compared to $0.3 million in Q2 2023. • Non-GAAP net income of $1.8 million, compared to $0.8 million in Q2 2023. • GAAP basic and diluted net loss per share of $1.55. • Non-GAAP basic and diluted net income per share of $0.07. x August 2024 Silvaco Group, Inc.

Silvaco Group, Inc. (Nasdaq: SVCO) Appendix I - Reconciliation of GAAP to Non-GAAP Financials Measures (Disclaimer) 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 expenses, non-GAAP operating income (loss), non-GAAP net income (loss), non-GAAP net income (loss) per share and free cashflow. 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 operating expenses and non-GAAP operating income (loss) as our GAAP operating expenses and GAAP operating income (loss), in each case, adjusted to exclude certain costs, including certain transaction-related costs, IPO preparation costs, acquisition-related litigation claims and costs, stock-based compensation expense, amortization of acquired intangible assets, impairment charges, and executive severance costs. We define non-GAAP net income (loss) as our GAAP net income (loss) adjusted to exclude certain costs, including certain transaction-related costs, IPO preparation costs, acquisition-related litigation claims and costs, stock-based compensation expense, amortization of acquired intangible assets, impairment charges, executive severance costs, change in fair value of contingent consideration, foreign exchange (gain) loss, gain on extinguishment of debt, and the income tax effect on non-GAAP items. Our non-GAAP 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 margin, non-GAAP operating expenses, non-GAAP operating income (loss), non-GAAP net income (loss) and non-GAAP 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 operating expenses, non-GAAP operating income (loss), non-GAAP net income (loss) and non-GAAP 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 operating income (loss) and net income (loss) for these items to arrive at 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 operating income (loss), non-GAAP net income (loss) and non-GAAP net income (loss) per share, provide meaningful supplemental information regarding our performance. We define free cash flow as net cash (used in) provided by operating activities in the period minus capital expenditures. We believe that free cash flow is an important financial measure for use in evaluating the Company’s ability to generate additional cash from our business operations. Free cash flow should be considered in addition to, rather than as a substitute for net cash provided by operating activities as a measure of our liquidity. Additionally, our definition of free cash flow is limited and does not represent residual cash flows available for discretionary expenditures due to the fact that the measure does not deduct the payments required for debt service and other obligations or payments made for business acquisitions. Therefore, we believe it is important to view free cash flow as supplemental to our entire statement of cash flows. 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 August 2024 Silvaco Group, Inc.
