ROGERS CORP 10-Q

Item 4. Controls and Procedures EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES We conducted, with the participation of our Principal Executive Officer and our Chief Financial Officer, an evaluation of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d- 15(e) under the Exchange Act, as of June 30, 2025. Our disclosure controls and procedures are designed (i) to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and (ii) to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our Principal Executive Officer and our Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Based on their evaluation, our Principal Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were effective as of June 30, 2025. CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING We are in the process of a multi-year implementation of a new global ERP system, which will replace our existing operating and financial systems. The implementation is expected to occur in phases over the next several years. During the first quarter of 2025, we completed the implementation of our new ERP system for one of our manufacturing sites. The portion of the transition to the new ERP system that we have completed to date did not result in significant changes in our internal control over financial reporting. However, as the next phases of the updated processes are rolled out in connection with the ERP implementation, we will give appropriate consideration to whether these process changes necessitate changes in the design of and the testing for effectiveness of internal controls over financial reporting. There were no changes in the Company’s internal control over financial reporting during the second quarter of fiscal year ending December 31, 2025, that have materially affected or are reasonably likely to materially affect the Company’s internal control over financial reporting, as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act.
