1 1 Disclaimers Forward Looking Statements This presentation contains forward - looking statements as defined by the Private Securities Litigation Reform Act of 1995. These statements are based on the beliefs and assumptions of management. Although the Company believes that its plans, intentions, and expectations reflected in or suggested by these forward - looking statements are reasonab le, the Company cannot assure you that it will achieve or realize these plans, intentions, or expectations. Forward - looking statements are inherently subject to risks, uncertainties, and assumptions. Generally, statements that are not historical facts, including statements concerning the Company’s possible or assumed future actions, business strategies, events, or results of operations, are forward - looking statements. In some instances, these statements may be preceded by, followed by or include the words “believes,” “estimates,” “expects,” “projects,” “forecasts,” “may,” “will,” “should,” “seeks,” “plans,” “scheduled,” “anticipates” or “intends” or the ne gatives of these terms or variations of them or similar terminology. Forward - looking statements are not guarantees of performance. You should not put undue reliance on these statements which speak only as of the date hereof. You should understand that the following important factors, among others, could affect the Company’s future results and could cause those results or other outcomes to differ materially from those expressed or implied in the Company’s forward - looking statements: the outcome of any legal proceedings that may be instituted against the Company or others; the impacts of the ongoing COVID - 19 pandemic; the ability of the Company to grow and m anage growth profitably, maintain relationships with customers, compete within its industry and retain its key employees; the possibility that the Company may be adversely impacted by other economic conditions (includ ing the rapidly evolving conflict between Russian and the Ukraine), business, and/or competitive factors; future exchange and interest rates; and other risks and uncertainties included under “Risk Factors” in other Company fi lings that have been made or will be made with the Securities and Exchange Commission. The Company undertakes no obligations to update or revise publicly any forward - looking statements, whether as a result of new inform ation, future events or otherwise, except as required by law. Non - GAAP Financial Measures This presentation includes certain non - GAAP financial measures that are not prepared in accordance with accounting principles ge nerally accepted in the United States (“GAAP”) and that may be different from non - GAAP financial measures used by other companies. The Company believes EBITDA, Adjusted EBITDA, Adjusted Net Income and Adjusted EP S a re useful to investors in evaluating the Company’s financial performance. The Company uses these measures internally to establish forecasts, budgets and operational goals to manage and monitor its business, as w ell as evaluate its underlying historical performance and to measure incentive compensation, as we believe that these non - GAAP financial measures depict the true performance of the business by encompassing only relevant and con trollable events, enabling the Company to evaluate and plan more effectively for the future. Due to the forward - looking nature of the financial guidance included above, specific quantification of the charges excluded from the non - GAAP financial measures included in such financial guidance, including with respect to depreciation, amortization, interest, and taxes, that would be required to reconcile the non GAAP financial measures included in such financial guidance to GAAP measures are not available, so it is not feasible to provide accurate forecasted non - GAAP reconciliations without unreasonable effort. Consequently, no disclosure of estimated comparable GA AP measures is included, and no reconciliation of the forward - looking non - GAAP financial measures is included. In addition, the Company’s debt agreements contain covenants that use a variation of these measures for pu rposes of determining debt covenant compliance. The Company believes that investors should have access to the same set of tools that its management uses in analyzing operating results. EBITDA, Adjusted EBITDA, Adjust ed Net Income and Adjusted EPS should not be considered as measures of financial performance under U.S. GAAP, and the items excluded from EBITDA, Adjusted EBITDA, Adjusted Net Income and Adjusted EPS are significant co mpo nents in understanding and assessing the Company’s financial performance. Accordingly, these key business metrics have limitations as an analytical tool. They should not be considered as an alternative to net inc ome or any other performance measures derived in accordance with U.S. GAAP or as an alternative to cash flows from operating activities as a measure of the Company’s liquidity and may be different from similarly titled non - GAAP measures used by other companies. Please refer to the tables below for the reconciliation of net income to EBITDA, Adjusted EBITDA, Adjusted Net Income and Adjusted EPS for the quarters and nine months ended September 30, 202 2 and September 30, 2021. Industry and Market Information Statements in this presentation concerning our industry and the markets in which we operate, including our general expectatio ns and competitive position, business opportunity and market size, growth and share, are based on information from independent industry organizations and other third - party sources, data from our internal research and manage ment estimates. Management estimates are derived from publicly available information and the information and data referred to above and are based on assumptions and calculations made by us based upon our interpreta tio n of such information and data. The information and data referred to above are imprecise and may prove to be inaccurate because the information cannot always be verified with complete certainty due to the limitatio ns on the availability and reliability of raw data, the voluntary nature of the data gathering process and other limitations and uncertainties. As a result, please be aware that the data and statistical information in this prese nta tion may differ from information provided by our competitors or from information found in current or future studies conducted by market research institutes, consultancy firms or independent sources.
