Forward Looking Statements This presentation may contain “forward-looking statements” within the meaning of Section 21E of the Exchange Act, as amended. All statements, other than statements of fact, that address activities, events or developments that the Company or the Company’s management intend, expe ct, project, believe or anticipate will or may occur in the future are forward-looking statements. The Presentation includes estimated financial information and projections for the Company after giving effect to transactions that are expected to occur at the time of or prior to the Company’s emergence from chapter 11. All projections reflect numerous estimates and assumptions made by management of the Company with respect to its financial condition, the performance of its b usiness and conditions within its industry, general economic, market and financial conditions and numerous other factors, including the impact of COVID -19. The financial information presented in this Presentation reflects assumptions about the terms of the Company’s proposed exit financing and other post-emergence securities, including with respect to fees and interest rates, which may differ from actual terms, including fees or rates, and such differences may be material. Although the Company believes forward-looking statements are based upon reasonable assumptions, such statements involve known and unknown risks, uncertainties , and other factors, which may cause the actual results or performance of the Company to be materially different from any future results or performance expressed or implied by such forward-looking statements. Such risks and uncertainties include, but are not limited to those described in the Company’s annual report on Form 10-K for the year ended December 31, 2020, as well as in the Company’s other filings with the Securities and Exchange Commission, under the hea dings “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements.” In addition, many of the transactions set out in the Presentation remain subject to court approval, and the Company may not obtain financing or consummate the proposed transactions on the terms contemplated or at all. You are ca utioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this document. Forward-looking statements are not guarantees of future performance, and actual results, developments and business decisions may differ from those envisaged by the Company’s forward -looking statements. Non-GAAP Financial Measures This presentation includes Adjusted EBITDA and other financial measures not compliant with generally accepted accounting prin ciples in the United States (“GAAP”). Adjusted EBITDA is adjusted for certain items as presented in the section of the Appendix titled Adj. EBITDA Walkdown and may not be directly comparable to similar measures used by other companies in our industry, as other companies may define such measures different ly. Management believes that, when considered together with reported amounts, these measures are useful to investors and management in understanding our on going operations and in analysis of ongoing operating trends. Garrett believes that Adjusted EBITDA is an important indicator of operating performanc e because it excludes the effects of income taxes and certain other items, as well as the effects of financing and investing activities by eliminating the effects of interest and depreciation expenses and therefore more closely measures our operational performance. The non-GAAP metrics included in this presentation should be considered in addition to, and not as replacements for, the most comparable GAAP measure. For additional information, see our annual report on Form 10 -K for the year ended December 31, 2020.
