As previously disclosed, on October 1, 2018, Garrett Motion Inc. (the “Company”) was spun off (the “Spin-Off”) from Honeywell International Inc. (“Honeywell”). The Company’s Combined Interim Financial Statements included in its Quarterly Report on Form 10-Q for the quarter ended September 30, 2018 (the “Form 10-Q”), filed with the Securities and Exchange Commission (“SEC”) on November 6, 2018 are carve-out financial statements, as the Company was still part of Honeywell during the third quarter of 2018. The Company is providing, in Exhibit 99.1 to this Current Report on Form 8-K, unaudited pro forma combined statements of operations for the nine months ended September 30, 2018 and the year ended December 31, 2017, and an unaudited pro forma combined balance sheet as of September 30, 2018, which reflect the Company’s results and financial position as if the Spin-Off and related transactions had occurred as of January 1, 2017.

The unaudited pro forma financial information presented in Exhibit 99.1 does not in any way restate or revise the historical Combined Financial Statements of the Company included in the Company’s Registration Statement on Form 10, as amended and filed with the SEC on September 5, 2018, and the Form 10-Q. The unaudited pro forma financial information is provided as supplemental financial information that the Company believes may be of interest to the Company’s stockholders.

The information in Item 2.02 and Exhibit 99.1 of this Current Report on Form 8-K shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934 (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933 or the Exchange Act, except as expressly set forth by specific reference in such a filing.
