Forward Looking Statements This presentation contains “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of fact, that address activities, events or developments that we or our management intend, expect, proj ect, believe or anticipate will or may occur in the future are forward-looking statements including without limitation our statements regarding our anticipated financial performance, expectations regarding global automotive demand, anticipated growth of our gasoline business, trends in foreign exchange rates, the antici pated impact of the novel coronavirus (“COVID-19”) pandemic on our business, results of operations and financial position, estimated payments to Honeywell, and projections regarding our technology solutions. Although we believe 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 mater ially 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 our annual report on Form 10-K for the year ended December 31, 2019, as updated by our quarterly report on Form 10-Q for the three months ended March 31, 2020, as well as our other filings with the Securities and Exchange Commission, under the headings “Risk Factors” and “Cautio nary Statement Concerning Forward-Looking Statements.” You are cautioned 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 our forward-looking statements. Non-GAAP Financial Measures This presentation includes EBITDA, Adjusted EBITDA, Net to Consolidated EBITDA ratio, Consolidated Debt to Consolidated EBIT DA ratio, Adjusted Free Cash Flow, Consolidated EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Earnings Per Share (“EPS”), Cash flow from operations minus capital expenditures, Free Cash Flow, Adjusted Free Cash Flow Conversion, constant currency sales growth and other financial measures not compliant with generally accepted accounting principles in the United States (“GAAP”). The Non-GAAP financial measures provided herein are adjusted for certain items as presented in the Appendix containing Non-GAAP Reconciliations and may not be directly comparable to similar measures used by other companies in our industry, as other companies may define such measures differently. Management believes that, when considered together with reported amounts, the se measures are useful to investors and management in understanding our ongoing operations and in analysis of ongoing operating trends. Garrett believe s that Adjusted EBITDA, Adjusted EBITDA Margin and Consolidated EBITDA are important indicators of operating performance because they exclude the eff ects 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. These metrics 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, 2019 and our quarterly report on Form 10-Q for the three months ended March 31, 2020.
