Use of Non-GAAP Financial Measures

This press release includes references to non-GAAP financial measures, including Adjusted EBITDA, Adjusted net income, and Diluted adjusted net income per share (the “Company’s Non-GAAP Financial Measures”). These non-GAAP financial measures are not based on any comprehensive set of accounting rules or principles and should not be considered a substitute for, or superior to, financial measures calculated in accordance with GAAP, and may be different from non-GAAP financial measures used by other companies. In addition, the Company’s Non-GAAP Financial Measures should be read in conjunction with the Company’s financial statements prepared in accordance with GAAP. The reconciliations of the Company’s Non-GAAP Financial Measures to the corresponding GAAP measures should be carefully evaluated.

The Company’s Non-GAAP Financial Measures are non-GAAP measures of the Company’s operating performance and should not be considered as an alternative to net income as a measure of financial performance or any other performance measure derived in accordance with U.S. GAAP and should not be construed as an inference that the Company’s future results will be unaffected by unusual or nonrecurring items. Adjusted EBITDA is defined as net income before interest expense, net, income tax provision, depreciation and amortization expense, (gain) loss on sale of assets, net, stock-based compensation expense, acquisition expenses, non-cash rent expense, expenses associated with the IPO, and other nonrecurring charges. Adjusted net income is defined as net income before (gain) loss on sale of assets, net, stock-based compensation expense, acquisition expenses, non-cash rent expense, expenses associated with the Company’s initial public offering, other nonrecurring charges, tax benefits related to stock awards

exercised and the tax impact of adjustments to net income. Adjusted net income per share is defined as basic net income per share before (gain) loss on sale of assets, net, stock-based compensation expense, acquisition expenses, non-cash rent expense, expenses associated with the Company’s initial public offering, other nonrecurring charges, tax benefits related to stock awards exercised and the tax impact of adjustments to basic net income per share. Diluted adjusted net income per share is defined as diluted net income per share before (gain) loss on sale of assets, net, stock-based compensation expense, acquisition expenses, non-cash rent expense, expenses associated with the IPO, other nonrecurring charges, tax benefits related to stock awards exercised and the tax impact of adjustments to basic net income per share.

Management believes the Company’s Non-GAAP Financial Measures assist investors and analysts in comparing the Company’s operating performance across reporting periods on a consistent basis by excluding items that management does not believe are indicative of the Company’s ongoing operating performance. Investors are encouraged to evaluate these adjustments and the reasons the Company considers them appropriate for supplemental analysis. In evaluating Company’s Non-GAAP Financial Measures, investors should be aware that in the future the Company may incur expenses that are the same as or similar to some of the adjustments in the Company’s presentation of Company’s Non-GAAP Financial Measures. The Company’s presentation of Company’s Non-GAAP Financial Measures should not be construed as an inference that the Company’s future results will be unaffected by unusual or nonrecurring items. There can be no assurance that the Company will not modify the presentation of the Company’s Non-GAAP Financial Measures in future periods, and any such modification may be material. In addition, the Company’s Non-GAAP Financial Measures may not be comparable to similarly titled measures used by other companies in the Company’s industry or across different industries.

Management believes that the Company’s Non-GAAP Financial Measures are helpful in highlighting trends in the Company’s core operating performance compared to other measures, which can differ significantly depending on long-term strategic decisions regarding capital structure, the tax jurisdictions in which companies operate and capital investments. Management also uses Adjusted EBITDA in connection with establishing discretionary annual incentive compensation; to supplement U.S. GAAP measures of performance in the evaluation of the effectiveness of the Company’s business strategies; to make budgeting decisions; and because the Company’s credit facilities use measures similar to Adjusted EBITDA to measure the Company’s compliance with certain covenants.

The Company’s Non-GAAP Financial Measures have limitations as analytical tools, and investors should not consider these measures in isolation or as substitutes for analysis of the Company’s results as reported under U.S. GAAP. Some of these limitations include, for example, Adjusted EBITDA does not reflect: the Company’s cash expenditure or future requirements for capital expenditures or contractual commitments; the Company’s cash requirements for the Company’s working capital needs; the interest expense and the cash requirements necessary to service interest or principal payments on the Company’s debt; cash requirements for replacement of assets that are being depreciated and amortized; and the impact of certain cash charges or cash receipts resulting from matters management does not find indicative of the Company’s ongoing operations. In addition, other companies in the Company’s industry may calculate similarly titled non-GAAP financial measures differently than the Company.

The Company is not providing a reconciliation of the fiscal 2023 outlook for Adjusted EBITDA, Adjusted net income and Diluted adjusted net income per share because we are unable to predict with reasonable certainty the reconciling items that may affect the most directly comparable GAAP financial measures without unreasonable efforts. The amounts that are necessary for such reconciliations, including acquisition expenses, other expenses and the other adjustments reflected are uncertain, depend on various factors and could significantly impact, either individually or in the aggregate, the GAAP measures.
