Use of Non-GAAP Financial Measures

This release contains the following non-GAAP measures: adjusted EBITDA (adjusted net earnings before interest, taxes, depreciation, and amortization) margin and adjusted diluted EPS (adjusted net earnings per diluted share). These measures are used by the Company to provide meaningful supplemental information about its operating performance by excluding amounts that are not considered part of core operating results to enhance comparability of results from period to period. Management uses non-GAAP measures to evaluate the Company’s historical and prospective financial performance, measure operational profitability on a consistent basis, as a factor in determining executive compensation, and to provide enhanced transparency to the investment community. Non-GAAP measures should be viewed in addition to, and not as a substitute for, the reported financial results of the Company prepared in accordance with GAAP. Other companies may calculate these measures differently, limiting the usefulness of the measures for comparison with other companies. The Company is not providing reconciliations for these forward-looking non-GAAP financial measures because the Company is unable to predict with reasonable certainty the ultimate outcome of adjusted items without unreasonable efforts. These items are uncertain, depend on various factors and could be material to financial results computed in accordance with GAAP.
