Additional information on potential risks, uncertainties and other factors that could affect Synopsys' results is included in filings we make with the SEC from time to time, including in the sections entitled "Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended October 31, 2022 and in our latest Quarterly Report on Form 10-Q. The financial information contained in this presentation should be read in conjunction with the consolidated financial statements and notes thereto included in Synopsys' most recent reports on Forms 10-K and 10-Q, each as may be amended from time to time. Synopsys' financial results for its second quarter of fiscal year 2023 are not necessarily indicative of Synopsys' operating results for any future periods. The information provided herein is as of May 17, 2023. Synopsys undertakes no duty to, and does not intend to, update any forward-looking statement, whether as a result of new information, future events or otherwise, unless required by law. synopsys® Regulation G In addition to financial results prepared in accordance with Generally Accepted Accounting Principles, or GAAP, this presentation also contains certain non- GAAP financial measures. When possible, Synopsys provides a reconciliation of non-GAAP financial measures to their most closely applicable GAAP financial measures. Reconciliations of certain of the non-GAAP financial measures (either contained in this presentation or given verbally) to their most comparable GAAP measures are included in the table at the end of this presentation, along with the second quarter of fiscal year 2023 earnings release and financial supplement, dated May 17, 2023, and available on Synopsys' website at https://investor.synopsys.com/news/default.aspx. Synopsys is unable to provide a reconciliation of certain non-GAAP guidance measures to the corresponding GAAP measures on a forward-looking basis because doing so would not be possible without unreasonable effort due to, among other things, the potential variability and limited visibility of the excluded items. For the same reasons, Synopsys is unable to address the probable significance of the unavailable information. © 2023 Synopsys, Inc. 2
