These forward-looking statements are subject to numerous risks and uncertainties, many of which are difficult to predict, and generally beyond our control. Actual results may differ materially from those indicated or implied by such forward-looking statements. For information on identified risks and uncertainties that could impact our forecasts, expectations, and results of operations, please review the risk factors and other information disclosed from time to time in our filings with the Securities and Exchange Commission. This presentation references “Adjusted EBITDA,” a non-GAAP financial measure. This non- GAAP measure is not intended to be an alternative to any measure calculated in accordance with GAAP. We believe the presentation of Adjusted EBITDA provides useful information to investors in assessing our financial condition and results of operations. Net income is the GAAP measure most directly comparable to Adjusted EBITDA. Non-GAAP financial measures have important limitations as analytical tools because they exclude some, but not all, items that affect the most directly comparable GAAP financial measures. You should not consider Adjusted EBITDA in isolation or as a substitute for an analysis of our results as reported under GAAP. Further, Adjusted EBITDA may be defined differently by other companies in our industry, and our definition of Adjusted EBITDA may not be comparable to similarly titled measures of other companies, thereby diminishing their utility. A reconciliation of non-GAAP measures to the most directly comparable measures calculated in accordance with GAAP, is set forth in the Appendix hereto. FORWARD-LOOKING STATEMENTS
