DISCLAIMER (cont.) Non-U.S.-GAAP Financial Measures This presentation includes certain financial information that is not presented in accordance with The U.S. GAAP, including Adjusted EBITDA and Adjusted EBITDA Margin. We refer to these measures as “non-U.S. GAAP” financial measures. We present these non-U.S. GAAP measures as we believe that their presentation of these enhances an investor’s understanding of our financial performance. Although these non-U.S. GAAP measures are frequently used by investors and securities analysts in their evaluations of companies in industries similar to ours, these non-U.S. GAAP measures have limitations as analytical tools, are not measurements of our performance under U.S. GAAP and should not be considered as alternatives to net income or any other performance measures derived in accordance with U.S. GAAP and should not be used by investors or other users of our financial statements in isolation for formulating decisions, as such non-U.S. GAAP measures exclude a number of important cash and non-cash charges. You should be aware that our presentation of these and other non-U.S. GAAP financial measures in this presentation may not be comparable to similarly titled measures used by other companies. A reconciliation of each of these non-U.S. GAAP measures to its most directly comparable financial measure calculated in accordance with U.S. GAAP is provided in the Appendix to this presentation. Industry and Market Data Within this presentation, we reference information and statistics regarding the market for our products and services. We have obtained some of this statistical data, market data and other industry data from public filings, industry publications and studies conducted by third-party sources. Some data and other information contained in this presentation are also based on management’s estimates and calculations, which are derived from our review and interpretation of internal surveys and independent sources. Data regarding the industries in which we compete and our market position and market share within these industries are inherently imprecise and are subject to significant business, economic and competitive uncertainties beyond our control, but we believe they generally indicate size, position and market share within this industry. In addition, assumptions and estimates of our and our industries’ future performance are necessarily subject to a high degree of uncertainty and risk due to a variety of factors. These and other factors could cause our future performance to differ materially from our assumptions and estimates.

This presentation also contains trademarks, tradenames, service marks and copyrights of other companies, which are, to our knowledge, the property of their respective owners.
