Exhibit 10.1

June 10, 2018

Mr. R. Bruce McDonald

Dear Bruce:

This letter agreement (“Letter Agreement”) sets forth the understanding between R. Bruce McDonald (“McDonald”), Adient plc (together with its subsidiaries, the “Company”) and Adient US LLC (the “Employer”) regarding McDonald’s retirement. Capitalized terms not otherwise defined in this Letter Agreement have the meaning set forth in the Key Executive Severance and Change of Control Agreement, dated January 17, 2017, by and among McDonald, the Company and the Employer (McDonald’s “Severance and Change of Control Agreement”).

(a) Senior Advisor. McDonald will cease to be Chairman and Chief Executive Officer of the Company effective June 11, 2018 (the “Transition Date”). McDonald will remain employed by the Employer as the Senior Advisor to the Chief Executive Officer, reporting to the Chief Executive Officer, from the Transition Date until September 30, 2018 when his retirement shall take effect (the “Retirement Date”, and the period from the Transition Date to the Retirement Date, the “Advisory Period”). As Senior Advisor, McDonald will perform such duties as are reasonably assigned to him by the Chief Executive Officer from time to time. McDonald and the Company agree that, effective as of the Transition Date, he will no longer serve as an officer of the Company.

(b) Transition from Other Positions. Effective as of the Transition Date, McDonald will cease to be a member of the Company’s Board of Directors and will resign from all director, officer and fiduciary positions that he holds with the Company and any of the Company’s subsidiaries, affiliates, joint ventures and other related entities. On the date of execution of this Letter Agreement, McDonald will deliver an executed resignation letter to the Company’s Board of Directors in the form attached as Exhibit A hereto.

(a) Base Salary. During the Advisory Period, McDonald will continue to be paid his base salary at his current rate, and consistent with the current payment schedule.

(b) Annual Incentive Bonus. McDonald will not be eligible to receive a bonus for the fiscal year ending September 30, 2018.

(c) Equity Awards. During McDonald’s continued employment through the Advisory Period, all of his outstanding restricted stock units (“RSUs”), performance share units (“PSUs”) and stock option awards will continue to vest and be earned and, for stock options, be exercisable, in accordance with their current terms. McDonald will receive no further equity awards under the Company’s equity incentive plans.

(d) Pension and Welfare Benefits. During the Advisory Period, McDonald will continue to be eligible to participate in the Employer’s 401(k) Plan, Retirement Restoration Plan and welfare benefit plans. McDonald will participate in the Employer’s Savings and Investment Plan (the RIC) to the same extent as senior executives of the Company. McDonald will also continue to receive the 5% perquisite allowance and participate in the car lease program during the Advisory Period.

(e) Business Expenses. During the periods in which McDonald is employed by the Employer as Senior Advisor, the Company will reimburse any business expenses incurred by him in accordance with applicable Company policies.

(f) Treatment of Outstanding Company Equity Awards on the Retirement Date. Upon the Retirement Date, the Company equity awards granted to McDonald before 2017 will receive the “Retirement” treatment set forth in Exhibit B. The Company equity awards granted in 2017 will be forfeited on the Retirement Date. The amount of equity award units that will vest upon the Retirement Date pursuant to the Retirement Treatment set forth in Exhibit B will not be reduced by the Company, subject to the terms of the Company’s Executive Incentive Compensation Recoupment Policy (the “Clawback Policy”) that will continue to apply to McDonald. The Company agrees to reasonably cooperate in connection with any reasonable request by McDonald or Johnson Controls International plc (“JCI”) regarding the effect of McDonald’s retirement from the Company in relation to his outstanding JCI equity awards. In the event of McDonald’s death after the Retirement Date, the Company equity awards will be treated in accordance with the terms of the Company’s 2016 Omnibus Incentive Plan.

(g) Relocation Benefits. The Employer will pay McDonald $250,000 for relocation expenses, within ten (10) days of McDonald’s Retirement Date.

(h) No Severance Benefits. McDonald will not be entitled to any other severance payments or benefits. McDonald agrees that the changes to his position, duties, responsibilities, compensation, work location and other terms and conditions of employment contemplated by this Letter Agreement do not constitute “Good Reason” for him to resign (as set forth in his Severance and Change of Control Agreement, or any other agreement he has with the Company or Employer).

(i) Irish Tax Filings. Tax services related to filings in Ireland will be provided at the Company’s expense for calendar year 2018 consistent with the Company’s past practice.

(a) General Waiver and Release. McDonald’s eligibility for the equity award treatment and benefits provided in Section 2 above will be contingent on his execution (and non-revocation) of a release of claims in favor of the Company (the “Release”). The form of Release is attached as Exhibit C and must be executed by McDonald (1) in connection with the execution of this Letter Agreement and (2) again upon his termination of employment, in each case within the time period specified in the Release.

(a) Ongoing Obligations. McDonald agrees and acknowledges that his obligations under Article III (Restrictive Covenants) of his Severance and Change of Control Agreement will continue in accordance with their terms (including for the 18-month “Restricted Period” after the Retirement Date to the extent set forth in such covenants). McDonald affirms that such provisions are not unduly burdensome to him and are reasonably necessary to protect the legitimate interests of the Company and the Employer.

(b) Clawback Policy. The Clawback Policy will continue to apply to McDonald.

(c) No Trading, Pledging or Hedging. During the Advisory Period, McDonald will continue to be subject to the Company’s Insider Trading Policy, including the Additional Provisions for Directors and Section 16 Officers of such policy (as if he were a director or Section 16 Officer).

(d) Future Cooperation. McDonald agrees that upon the Company’s reasonable request following the Advisory Period, he will use reasonable efforts to assist and cooperate with the Company in connection with the defense or prosecution of any claim that may be made against or by the Company arising out of events occurring during your employment, or in connection with any ongoing or future investigation or dispute or claim of any kind involving the Company. McDonald will be entitled to reasonable out-of-pocket expenses (including travel expenses) incurred in connection with providing such assistance, and if such assistance requires four (4) or more hours in one day, McDonald will also be entitled to reimbursement at a per-diem rate of $1,500.

(e) Whistleblower Policy. McDonald understands and agrees that nothing in this Letter Agreement limits or interferes with his right, without notice to or authorization from the Company, to file a charge or complaint with the Equal Employment Opportunity Commission, the National Labor Relations Board, the Occupational Safety and Health Administration, the U.S. Securities and Exchange Commission, the Financial Industry Regulatory Authority, or any other self-regulatory organization or any other federal, state or local governmental agency or commission (each a “Governmental Agency”), or to testify, assist or participate in any investigation, hearing or proceeding conducted by a Governmental Agency. In the event McDonald files a charge or complaint with a Government Agency, or a Government Agency asserts a claim on his behalf, he agrees that his release of Claims in this Letter Agreement will nevertheless bar his right (if any) to any monetary or other recovery (including reinstatement), except that he does not waive: (1) his right to receive an award from the Securities and Exchange Commission pursuant to Section 21F of the Securities Exchange Act of 1934 and (2) any other right where waiver is expressly prohibited by law.

(a) Tax Withholding. The Company may withhold from any amounts payable to McDonald under this Letter Agreement any federal, state, local or foreign taxes that are required to be withheld pursuant to applicable law or regulation.

-3-

(b) No Representations and Non-Admission. McDonald acknowledges that he has not relied on any representations or statements in determining to execute this Letter Agreement. Nothing contained in this Letter Agreement will be deemed or construed as an admission of wrongdoing or liability by McDonald or on the part of the Company or its present or past affiliates, officers, directors, executives or agents.

(c) Entire Understanding. This Letter Agreement sets forth the entire agreement between McDonald, the Company and the Employer regarding his transition to Senior Advisor and his ultimate retirement, and supersedes any other agreements, including, but not limited to, his Severance and Change of Control Agreement and all applicable equity award agreements, between McDonald and the Company except as set forth herein.

(d) Dispute Resolution; Governing Law. This Letter Agreement will be construed and enforced according to the internal laws of the State of Michigan, without reference to the choice of law provisions thereof. McDonald irrevocably and unconditionally (a) agrees that any suit, action or other legal proceeding arising under this Letter Agreement may be brought in the United States District Court for the Eastern District of Michigan, or if such court does not have jurisdiction or will not accept jurisdiction, in any court of general jurisdiction in Michigan, (b) consent to be subject to the nonexclusive personal jurisdiction of any such court in any such suit, action or proceeding, and (c) waive any objection which you may have to the laying of venue of any such suit, action or proceeding in any such court. The Employer is a Michigan limited liability company. The responsibilities of McDonald’s employment have substantial relation to the Employer’s business in Michigan.

(e) Severability; Counterparts. The invalidity or unenforceability of any provision of this Letter Agreement will not affect the validity or enforceability of any other provision. If any provision of this Letter Agreement is held invalid or unenforceable in part, the remaining portion of such provision, together with all other provisions of this Letter Agreement, will remain valid and enforceable and continue in full force and effect to the fullest extent consistent with law. This Letter Agreement may be executed in several counterparts, each of which will be deemed an original, and such counterparts will constitute one and the same instrument.

(f) Section 409A of the Code. It is the parties’ intent that the payments and benefits provided under this Letter Agreement be exempt from, or comply with, Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and this Letter Agreement will be interpreted accordingly. In this regard each payment under this Letter Agreement will be treated as a separate payment for purposes of Section 409A of the Code. If and to the extent that any payment or benefit is determined by the Company (1) to constitute “non-qualified deferred compensation” subject to Section 409A of the Code and (2) such payment or benefit must be delayed for six months following your separation from service in order to comply with Section 409A(a)(2)(B)(i) of the Code and not cause you to incur any additional tax under Section 409A of the Code, then the Company will delay making any such payment or providing such benefit until the expiration of such six-month period (or, if earlier, your death or a “change in control event” as such term is defined in Section 1.409A-3(i)(5) of the Code). All reimbursements and in-kind benefits provided under this Letter Agreement will be made or provided in accordance with the requirements of Section 409A of the Code, including, where applicable, the requirement that (i) the amount of expenses eligible for reimbursement, or in-kind benefits provided, during a calendar year may not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other calendar year (except that a plan providing health benefits

-4-

may impose a generally applicable limit on the amount that may be reimbursed or paid); (ii) the right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another benefit; and (iii) any reimbursement of an expense must be made on or before the last day of the calendar year following the calendar year in which the expense was incurred.
