Item 9A. Controls and Procedures

(a)Evaluation of Disclosure Controls and Procedures. As of October 31, 2025, Synopsys carried out an evaluation under the supervision and with the participation of Synopsys' management, including the Chief Executive Officer and Chief Financial Officer, 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 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 Chief Executive Officer and Chief Financial Officer have concluded that, as of October 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 Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding its required disclosure.

(b)Management's Report on Internal Control Over Financial Reporting. Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) for Synopsys.

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of October 31, 2025. In assessing the effectiveness of our internal control over financial reporting, our management used the framework established in Internal Control Integrated Framework (2013) issued by The Committee of Sponsoring Organizations of the Treadway Commission (COSO).

Our management has concluded that, as of October 31, 2025, our internal control over financial reporting was effective based on these criteria.

We acquired Ansys during fiscal 2025 and have excluded Ansys from our assessment of the effectiveness of our internal control over financial reporting as of October 31, 2025. Total assets and total revenues of Ansys represent approximately 21% and 11% of each of our total consolidated assets and of total consolidated revenue as of and for the year ended October 31, 2025.

Our independent registered public accounting firm, KPMG LLP, has issued an auditors' report on the effectiveness of our internal control over financial reporting, which is included herein.

(c)Changes in Internal Control Over Financial Reporting. There were no changes in Synopsys' internal control over financial reporting during the fiscal quarter ended October 31, 2025 that have materially affected, or are reasonably likely to materially affect, Synopsys' 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.
