Raising 2023 Outlook Raising Full-Year Adjusted EPS* Outlook to a new range of $2.21 to $2.43, from the previous range of $2.15 to $2.40 Would represent highest EPS in Company's history and YoY growth of 13%-24%, despite aggregate headwind of -$0.23 from higher interest expense and normalization of tax rate Key Assumptions Also raising low end of full-year net sales outlook by $40 M, establishing new range of $1.62 B to $1.72 B Represents YoY growth of 13% - 20% vs. $1.43 B in 2022 ■ Double-digit improvement in pre-tax earnings ■ Depreciation and amortization expense of ~$62 M - $64 M ■ Capital expenditures of $25 M to $30 M ■ Interest expense of ~$20-21 M; YoY EPS headwind of ~$0.13 Effective tax rate resets to a normalized rate between 24% and 25%, excluding additional discrete items; YoY EPS headwind of ~$0.10 ~61-62 M weighted average shares outstanding ■ No significant deterioration in current supply chain environment; assumes supply chain improves throughout year, with steady flow of customer-provided chassis ■ No significant increase in current input costs ■Includes nominal contribution from Trackless acquisition *Adjusted earnings per share ("EPS") is a non-GAAP measure, which includes certain adjustments to reported GAAP net income and diluted EPS. In 2022, we made adjustments to exclude the impact of acquisition and integration-related expenses (benefits) and debt settlement charges, where applicable. Should any similar items occur in 2023, 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). ם FEDERAL SIGNAL 11
