Item 1. Security and Issuer.

This Amendment No. 7 amends the Schedule 13D filed on October 29, 2020 (the “Original Schedule 13D” and, as amended by Amendment No. 1 to Schedule 13D filed on November 3, 2020, Amendment No. 2 to Schedule 13D filed on November 17, 2020, Amendment No. 3 to Schedule 13D filed on December 23, 2020, Amendment No. 4 to Schedule 13D filed on January 12, 2021, Amendment No. 5 to Schedule 13D filed on January 27, 2021, Amendment No. 6 to Schedule 13D filed on February 17, 2021 and this Amendment No. 7, the “Schedule 13D”). This statement of beneficial ownership on Schedule 13D relates to the shares of common stock, $0.001 par value per share (the “Shares”), of Garrett Motion Inc., a Delaware corporation (the “Company”). According to the Company, the address of its principal executive office is La Pièce 16, Rolle, Switzerland 1180. Unless specifically amended hereby, the disclosures set forth in the Original Schedule 13D remain unchanged. Capitalized terms used but not otherwise defined herein have the meanings given to them in the Original Schedule 13D filed on October 29, 2020.

Item 4. Purpose of Transaction.

Item 4 of the Original Schedule 13D is hereby amended as follows:

On March 9, 2021, the Company and its affiliated Debtors entered into a Second Amended and Restated Plan Support Agreement (including all exhibits and schedules attached thereto, the “Second Amended Plan Support Agreement”) with the Plan Sponsors, Honeywell International Inc. (“Honeywell” or the “Reporting Person”) and the Additional Investors (each as defined therein), setting forth the terms by which the foregoing parties committed to provide capital to and/or support the Company in connection with its plan of reorganization. The Second Amended Plan Support Agreement amended and restated the Amended Plan Support Agreement, entered into by the Debtors, the Plan Sponsors, Honeywell, the Additional Investors, the Initial Consenting Noteholders (as defined in the Second Amended Plan Support Agreement), and the Initial Consenting Lenders (as defined in the Second Amended Plan Support Agreement) on February 15, 2021 and terminated the Equity Backstop Commitment Agreement, entered into by the Debtors, the Plan Sponsors, and certain of the Additional Investors on January 22, 2021 (the “Original BCA”) and certain equity commitment letters previously provided by the Additional Investors to the Debtors. The Second Amended Plan Support Agreement is filed as Exhibit 99.1 hereto and incorporated by reference.

On the same day, the Company and the other Debtors (as defined therein) entered into a Replacement Equity Backstop Commitment Agreement (the “Replacement BCA”) with the Equity Backstop Parties (as defined therein), setting forth the terms by which the Equity Backstop Parties committed to participate in a rights offering to provide capital to the Debtors in connection with the Debtors’ plan of reorganization. The Replacement BCA replaced the Original BCA and supplements the Second Amended and Restated Plan Support Agreement. The Replacement BCA is filed as Exhibit 99.2 hereto and incorporated by reference.

The Reporting Person by itself or with the Additional Investors, the Plan Sponsors, and the Initial Consenting Noteholders (to the extent they own Shares) may be deemed to constitute a group for purposes of Rule 13d-3 under the Act. The Reporting Person anticipates that the Plan Sponsors, the Additional Investors and the Initial Consenting Noteholders will file separate statements of beneficial ownership on Schedule 13D pursuant to Rule 13d-1(k)(2) under the Act, and any amendments thereto, containing their required information. The Reporting Person assumes no responsibility for the information contained in any filings by any other person. The Reporting Person expressly disclaims beneficial ownership of any securities beneficially owned or acquired by any other person except to the extent of their pecuniary interest therein. As of the date of this Amendment No. 7, based on information provided by the Plan Sponsors, the Additional Investors and the Consenting Noteholders, the Reporting Person believes that the Reporting Person, the Plan Sponsors, the Additional Investors and the Consenting Noteholders beneficially own in the aggregate 57.4% of the 76,068,026 outstanding Shares, as set forth in Section 4.4 of the Replacement BCA.
