SYNOPSYS INC

(a)Evaluation of Disclosure Controls and Procedures. As of May 4, 2024, Synopsys carried out an evaluation under the supervision and with the participation of Synopsys’ management, including the Chief Executive Officer (CEO) and Chief Financial Officer (CFO), of the effectiveness of the design and operation of Synopsys’ disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act)). There are inherent limitations to the effectiveness of any system of disclosure controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable, not absolute, assurance of achieving their control objectives. Our CEO and CFO have concluded that, as of May 4, 2024, Synopsys’ disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in the reports Synopsys files and submits under the Exchange Act is recorded, processed, summarized and reported as and when required, and that such information is accumulated and communicated to Synopsys’ management, including the CEO and CFO, to allow timely decisions regarding its required disclosure.

(b)Changes in Internal Control over Financial Reporting. There were no changes in Synopsys’ internal control over financial reporting during the fiscal quarter ended May 4, 2024 that have materially affected, or are reasonably likely to materially affect, Synopsys’ internal control over financial reporting.
