SYNOPSYS INC

(a)Evaluation of Disclosure Controls and Procedures. As of July 31, 2025, 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)). Regardless of how well designed and operated, 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 compliance programs and compliance training for employees may not prevent our employees or contractors from breaching or circumventing our policies or violating applicable laws and regulations. Our CEO and CFO have concluded that, as of July 31, 2025, 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 was no change in our internal control over financial reporting identified in connection with the evaluation required by Rules 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the period covered by this report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. We are currently in the process of integrating the Ansys operations, control processes and information systems into our systems and control environment. We believe that we have taken the necessary steps to monitor and maintain appropriate internal controls over financial reporting during this integration.
