Sept 6, 2018 | GARRETT INVESTOR CONFERENCE – NYSE: GTX New York City

Disclosure ADDITIONAL INFORMATION For additional information with respect to Garrett and the proposed spin-off, please refer to the Form 10 Registration Statement, as it may be further amended, on file with the Securities and Exchange Commission. The spin-off is subject to customary conditions, including final approval by Honeywell’s board of directors. The financial information included in this document may not necessarily reflect Garrett’s financial position, results of operations, and cash flows in the future or what Garrett’s financial position, results of operations, and cash flows would have been had Garrett been an independent, publicly traded company during the periods presented. This communication shall not constitute an offer of any securities for sale, nor shall there be any offer, sale or distribution of securities in any jurisdiction in which such offer, sale or distribution would be unlawful prior to appropriate registration or qualification under the securities laws of such jurisdiction. FORWARD LOOKING STATEMENTS This presentation contains “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934. All statements, other than statements of fact, that address activities, events or developments that we or our management intend, expect, project, believe or anticipate will or may occur in the future are forward looking statements. 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 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 our Registration Statement on Form 10 under the headings “Risk Factors” and “Cautionary 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 Consolidated EBITDA, Consolidated EBITDA Margin, Adjusted EBITDA and Adjusted EBITDA Margin figures that are not compliant with generally accepted accounting principles in the United States (“GAAP”). The Non-GAAP financial measures provided herein are consolidated for certain items as presented in the 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. Consolidated EBITDA is defined in accordance with our proposed Credit Agreement and differs from EBITDA as presented herein. Management believes that, when considered together with reported amounts, these measures are useful to investors and management in understanding our ongoing operations and in analysis of ongoing operating trends. In addition, Consolidated EBITDA is used as part of our calculations with respect to compliance with certain debt covenants included in our proposed credit agreement. Garrett believes that Consolidated EBITDA, Consolidated EBITDA Margin, Adjusted EBITDA and Adjusted EBITDA Margin are important indicators of operating performance because they exclude the effects of income taxes and certain other expenses, 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. Refer to the Appendix attached to this presentation for reconciliations of Non-GAAP financial measures to the most directly comparable GAAP measures. For additional information with respect to our Unaudited Combined Financial Statements, see our Form 10.

Summary of Honeywell Indemnification Obligation What is the background? • Honeywell is transferring responsibility to Garrett for certain Transportation Systems liabilities in connection with the separation • The liabilities are comprised of asbestos liabilities, predominately Bendix, as well as some environmental liabilities • Bendix Corporation dates back to 1920s and historically sold brake pads that contained asbestos • Honeywell acquired Bendix through its merger with Allied Signal in 1999 and it became part of the TS business • Honeywell sold Bendix assets to Federal Mogul in 2014 and retained asbestos liabilities / claims • Today, Honeywell is a defendant in asbestos personal injury actions mainly related to legacy Bendix Friction Materials business Why create an Indemnity Agreement? • Garrett has entered into an indemnification agreement with Honeywell as a means to create an obligation for Garrett to pay annually while not transferring the actual legal obligation for the liability • Honeywell will retain legal obligation related to liability and continue to manage claims and administrative processes • In a given year, Garrett will not be responsible for more than $175mm payment, plus any accrued payment amounts in respect of any year, related to the indemnification agreement • Structure removes uncertainty for Garrett (i.e., payment cannot exceed cap plus accrued amounts), subordinates agreement to Garrett’s senior debt, and means Garrett can benefit from Honeywell’s administration infrastructure already in place • Honeywell will continue to be responsible for 10% of the Bendix payment and will therefore have incentives aligned with Garrett to minimize annual payments and effectively manage the settlement of claims as they have done historically Copyrights © 2018 Garrett Motion Inc.
