6/4/24 Silvaco Group, Inc. Financial Results 3 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) and non-GAAP net income (loss), non-GAAP diluted earnings (loss) per share, and free cash flow. 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 acquisition-related litigation costs, executive severance, amortization of acquired intangible assets, IPO preparation costs, regulatory compliance costs and impairment charges. We define non-GAAP net income (loss) as our GAAP net income (loss) adjusted to exclude certain costs, including acquisition-related litigation costs, executive severance, amortization of acquired intangible assets, IPO preparation costs, regulatory compliance costs, impairment charges, change in fair value of contingent consideration, foreign exchange (gain) loss, and gain on extinguishment of debt. Our non-GAAP earnings per share is calculate 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 expenses, non-GAAP operating income (loss), non-GAAP net income (loss) and non-GAAP net earnings 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 on-GAAP operating expenses, non-GAAP operating income (loss), non-GAAP net income (loss) and non-GAAP net earnings per share because these items are noncash 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 diluted earnings (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
