Cooper-Standard Holdings Inc.

Evaluation of Disclosure Controls and Procedures

The Company has evaluated, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, the effectiveness of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of December 31, 2025. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. However, based on that evaluation, the Company’s Chief Executive Officer along with the Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective at a reasonable assurance level as of December 31, 2025.
