Adjusted earnings per share (“EPS”) is a non-GAAP measure, which includes certain adjustments to reported GAAP net income and diluted EPS. In the three months ended March 31, 2025 and 2024, we made adjustments to exclude the impact of acquisition and integration-related expenses, net, purchase accounting effects, and certain special income tax items, where applicable. In prior years, we have also made adjustments to exclude the impact of environmental remediation costs of a discontinued operation, pension-related charges, and certain other unusual or non- recurring items. Should any similar items occur in the remainder of 2025, we would expect to exclude them from the determination of adjusted EPS. However, because of the underlying uncertainty in quantifying amounts which may not yet be known, a reconciliation of our Adjusted EPS outlook to the most applicable GAAP measure is excluded based on the unreasonable efforts exception in Item 10(e)(1)(i)(B).

Federal Signal Q1 2025 Earnings Call 14 Appendix

Non-GAAP Measures 15 • Adjusted net income and earnings per share (“EPS”) - The Company believes that modifying its 2025 and 2024 net income and diluted EPS provides additional measures to assist it in comparing its performance on a consistent basis for purposes of business decision making by removing the impact of certain items that management believes are not representative of its underlying performance and to improve the comparability of results across reporting periods. During the three months ended March 31, 2025 and 2024 adjustments were made to reported GAAP net income and diluted EPS to exclude the impact of acquisition and integration-related expenses, net, purchase accounting effects, and certain special income tax items, where applicable. • Adjusted EBITDA and adjusted EBITDA margin - The Company uses adjusted EBITDA and the ratio of adjusted EBITDA to net sales (“adjusted EBITDA margin”), at both the consolidated and segment level, as additional measures to assist in comparing its performance on a consistent basis for purposes of business decision making by removing the impact of certain items that management believes are not representative of its underlying performance and to improve the comparability of results across reporting periods. We believe that investors use versions of these metrics in a similar manner. For these reasons, the Company believes that adjusted EBITDA and adjusted EBITDA margin, at both the consolidated and segment level, are meaningful metrics to investors in evaluating the Company’s underlying financial performance. • Consolidated adjusted EBITDA is a non-GAAP measure that represents the total of net income, interest expense, net, acquisition and integration-related expenses, net, purchase accounting effects, other expense, net, income tax expense (benefit), and depreciation and amortization expense, as applicable. Consolidated adjusted EBITDA margin is a non-GAAP measure that represents the total of net income, interest expense, net, acquisition and integration-related expenses, net, purchase accounting effects, other expense, net, income tax expense (benefit), and depreciation and amortization expense, as applicable, divided by net sales for the applicable period(s). • Segment adjusted EBITDA is a non-GAAP measure that represents the total of segment operating income, acquisition and integration-related expenses, net, purchase accounting effects, and depreciation and amortization expense, as applicable. Segment adjusted EBITDA margin is a non-GAAP measure that represents the total of segment operating income, acquisition and integration-related expenses, net, purchase accounting effects, and depreciation and amortization expense, as applicable, divided by segment net sales for the applicable period(s). Segment operating income includes all revenues, costs and expenses directly related to the segment involved. In determining segment operating income, neither corporate nor interest expenses are included. Segment depreciation and amortization expense relates to those assets, both tangible and intangible, that are utilized by the respective segment. Other companies may use different methods to calculate adjusted EBITDA and adjusted EBITDA margin.
