2023 Outlook Adjusted EPS* ranging from $2.15 to $2.40 Would represent highest EPS in Company’s history and YoY growth of 10%-22%, despite aggregate headwind of ~$0.23 from higher interest expense and normalization of tax rate 16  Revenue of $1.58 B to $1.72 B; represents YoY growth of 10%- 20% vs. $1.43 B in 2022  Double-digit improvement in pre-tax earnings  Depreciation and amortization expense of ~$62 M -$65 M  Capital expenditures of $25 M to $30 M  Interest expense of ~$18-20 M; YoY EPS headwind of ~$0.11  Effective tax rate resets to a normalized rate between 25% and 26%, excluding discrete items; YoY EPS headwind of ~$0.12  ~61-62 M weighted average shares outstanding Key Assumptions  YoY earnings improvement expected in Q1, although seasonal effects typically result in Q1 earnings being lower than subsequent quarters  Expect Q1 2023 earnings to represent similar % of full- year earnings as in 2022  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, expected to close during Q2 *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).

Appendix V: Non-GAAP Measures (Adjusted EPS) 27 Adjusted net income and earnings per share (“EPS”) The Company believes that modifying its 2022 and 2021 net income and diluted EPS provides additional measures which are representative of the Company’s underlying performance and improves the comparability of results between reporting periods. During the years ended December 31, 2022 and 2021, adjustments were made to reported GAAP net income and diluted EPS to exclude the impact of acquisition and integration-related benefits, pension-related charges, coronavirus-related expenses, debt settlement charges, and purchase accounting effects, where applicable. ($ in millions, except per share data) 2022 2021 Net income 120.4$ 100.6$ Add (less): Income tax expense 30.5 17.0 Income before income taxes 150.9 117.6 Add (less): Acquisition and integration-related benefits (0.5) (2.1) Pension-related charges (1) - 10.6 Coronavirus-related expenses (2) - 1.2 Debt settlement charges 0.1 - Purchase accounting effects (3) - 0.7 Adjusted income before income taxes 150.5 128.0 Adjusted income tax expense (4) (30.4) (19.6) Adjusted net income 120.1$ 108.4$ Diluted EPS 1.97$ 1.63$ Adjusted diluted EPS 1.96$ 1.75$ (4) Adjusted income tax expense for the twelve months ended December 31, 2022 and 2021 was recomputed after excluding the impact of acquisition and integration-related benefits, pension-related charges, coronavirus-related expenses, debt settlement charges, and purchase accounting effects, where applicable. Year Ended December 31, (1) Pension-related charges in the twelve months ended December 31, 2021 primarily relate to pension settlement charges incurred in connection with a pension annuitization project. (2) Coronavirus-related expenses in the twelve months ended December 31, 2021 relate to direct expenses incurred in connection with the Company's response to the coronavirus pandemic, that are incremental to, and separable from, normal operations. Such expenses primarily relate to incremental paid time off provided to employees and costs incurred to implement enhanced workplace safety protocols. (3) Purchase accounting effects in the twelve months ended December 31, 2021 relate to adjustments to exclude the step-up in the valuation of equipment acquired in recent business combinations that was sold during the periods presented.

Appendix V: Non-GAAP Measures (Adjusted EBITDA) 28 Adjusted EBITDA and adjusted EBITDA margin The Company uses adjusted EBITDA and adjusted EBITDA margin as additional measures which are 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 are meaningful metrics to investors in evaluating the Company’s underlying financial performance. Adjusted EBITDA is a non-GAAP measure that represents the total of net income (from continuing operations), interest expense, pension settlement charges, hearing loss settlement charges, acquisition and integration-related expenses (benefits), coronavirus-related expenses, restructuring activity, executive severance costs, debt settlement charges, purchase accounting effects, other income/expense, income tax expense, depreciation and amortization expense, and the impact of adoption of a new lease accounting standard, where applicable. Consolidated adjusted EBITDA margin is a non-GAAP measure that represents the total of net income (from continuing operations), interest expense, pension settlement charges, hearing loss settlement charges, acquisition and integration-related expenses (benefits), coronavirus-related expenses, restructuring activity, executive severance costs, purchase accounting effects, other income/expense, income tax expense, depreciation and amortization expense, and the impact of adoption of a new lease accounting standard, where applicable, divided by net sales for the applicable period(s). Other companies may use different methods to calculate adjusted EBITDA and adjusted EBITDA margin.
