FEDERAL SIGNAL CORP /DE/

As required by Rule 13a-15 under the Exchange Act, the Company’s management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) or Rule 15d-15(e) under the Exchange Act) as of March 31, 2026. Based on that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of March 31, 2026.

As a matter of practice, the Company’s management continues to review and document internal control and procedures for financial reporting. From time to time, the Company may make changes aimed at enhancing the effectiveness of the controls and ensuring that the systems evolve with the business. SEC guidance permits management to omit an assessment of internal control over financial reporting for an acquired business from management’s assessment of internal control over financial reporting for a period not to exceed one year from the date of the acquisition. During the three months ended March 31, 2026, the Company completed the acquisition of Mega. The Company also completed the acquisition of New Way and certain assets and liabilities of Kinloch Equipment & Supply, Inc. (“Kinloch”) in the fourth quarter of 2025. As of March 31, 2026, management has not yet fully assessed Mega, New Way, or Kinloch’s internal controls over financial reporting. Excluding the acquisitions of Mega, New Way, and Kinloch, there were no changes in the Company’s internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting during the three months ended March 31, 2026.
