(a) Evaluation of disclosure controls and procedures

The company’s management has evaluated, with the participation of the Chief Executive Officer and Chief Financial Officer, the effectiveness of the company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this report. Based on this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the company’s disclosure controls and procedures were effective as of September 30, 2025.

(b) Changes in internal control over financial reporting

In the third quarter of 2025, the company significantly progressed a multi-year implementation of an updated global enterprise resource planning (ERP) system. As a result, the company made corresponding changes to its business processes and information systems, updating applicable internal control over financial reporting where necessary.

Except with respect to the ongoing implementation of ERP systems, there were no changes in the company’s internal control over financial reporting during the quarter ended September 30, 2025, that have materially affected, or are reasonably likely to materially affect, the company’s internal control over financial reporting.
