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).

Non‐GAAP Measures • 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 three and twelve months 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 expenses (benefits), pension‐related charges, coronavirus‐related expenses, debt settlement charges and purchase accounting effects, 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 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, 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, pension settlement charges, acquisition and integration‐related expenses (benefits), coronavirus‐related expenses, debt settlement charges, purchase accounting effects, other income/expense, income tax benefit/expense, and depreciation and amortization expense. Consolidated adjusted EBITDA margin is a non‐ GAAP measure that represents the total of net income, interest expense, pension settlement charges, acquisition and integration‐related expenses (benefits), coronavirus‐related expenses, debt settlement charges, purchase accounting effects, other income/expense, income tax benefit/expense, and depreciation and amortization expense 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, coronavirus‐related expenses, 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, coronavirus‐ related expenses, purchase accounting effects and depreciation and amortization expense, as applicable, divided by 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 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. 21
