Amendment to Offer Letter between Gentherm Incorporated and Vishnu Sundaram, dated as of February 5, 2024

Gentherm has established a Severance Pay Plan for Eligible Employees of Gentherm Incorporated dated January 29, 2021 (as amended from time to time, the “Plan”), which provides for Severance Benefits (as defined in the Plan) to be provided in the Company’s discretion to eligible employees whose employment is involuntarily terminated without Cause (as defined in the Plan) in accordance with the terms of the Plan;

The Parties agree that, if Executive is eligible for Severance Benefits in the event of an involuntary termination without Cause, the Company will provide such benefits to Executive notwithstanding its discretionary authority not to do so under the Plan, with such benefits to be provided in accordance with the other terms and requirements of the Plan, including but not limited to the release requirement set forth in Appendix B of the Plan; and

The Parties further agree that, if Executive resigns his employment with the Company for Good Reason (as defined below), then Executive will be eligible to receive the Severance Benefits under the Plan as if Executive had been involuntarily terminated without Cause, notwithstanding Gentherm’s discretionary authority not to provide benefits under the Plan in that circumstance, with such benefits to be provided in accordance with the other terms and requirements of the Plan, including but not limited to the release requirement set forth in Appendix B of the Plan.

For purposes of this Amendment, “Good Reason” means the occurrence of any of the following without Executive’s consent: (i) a material breach of the Offer Letter; (ii) a material diminution in Executive’s then-current compensation or benefits, authority, duties, or responsibilities, including following a Change in Control; (iii) a change in Executive’s primary work location to a location that is more than 50 miles away from

Executive’s primary work location as of the date of this Amendment; (iv) any successor’s failure to assume the Company’s duties and obligations under the terms of the Offer Letter and this Amendment; or (v) the Company’s termination of the Plan or an amendment thereof that results in a material diminution of the available Severance Benefits for Executive. Notwithstanding the above, no “Good Reason” will exist unless (x) Executive notifies the Company in writing within 30 days after the existence of any condition listed above, and the Company fails to cure the condition within 30 days after receiving notice, and (y) Executive terminates employment by no later than 45 days after the providing the notice.

If Executive’s employment is terminated by the Company or its successor without Cause or by Executive for Good Reason during the window period starting with the signing of an agreement to engage in a Change in Control (as defined below) until twelve (12) months after the Change in Control, then the Severance Benefits otherwise payable to Executive in accordance with Section 1 and the Plan will be increased as follows:

For purposes of this Amendment, a “Change in Control” means the earliest to occur of any of the following events, each of which must also constitute a “change in control event” within the meaning of Treas. Reg. section 1.409A-3(i)(5): (i) any one Person or more than one Person Acting as a Group (each as defined below) acquires, or has acquired during the 12-month period ending on the date of the most recent acquisition by such Person or Group, beneficial ownership of more than a majority of the total fair market value or total voting power of the then-outstanding stock of the Company; (ii) any one Person or more than one Person Acting as a Group acquires, or has acquired during the 12-

month period ending on the date of the most recent acquisition by such Person or Group, the assets of the Company that have a total gross fair market value (as determined by Gentherm’s Board of Directors (the “Board”)) of more than 50% of the total gross fair market value of all of the assets of the Company immediately prior to the initiation of the acquisition; or (iii) a majority of the members of the Board is replaced during any 12-month period by directors whose appointment or election is not endorsed or approved by a majority of the members of the Board who were members of the Board prior to the initiation of the replacement.

For purposes of this Amendment, a “Person” means any individual, entity or group within the meaning of section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), other than (i) the Company, (ii) any trustee or other fiduciary holding securities under an employee benefit plan of the Company, or (iii) any corporation owned, directly or indirectly, by the shareholders of the Company in substantially the same proportions as their ownership of stock of the Company. Persons will be considered to be “Acting as a Group” (or a “Group”) if they are a “group” as defined under Section 13 of the Exchange Act. If a Person owns equity interests in both entities that enter into a merger, consolidation, purchase or acquisition of stock, or similar transaction, such shareholder is considered to be Acting as a Group with other shareholders only with respect to the ownership in that entity before the transaction giving rise to the change and not with respect to the ownership interest in the other entity. Persons will not be considered to be Acting as a Group solely because they purchase assets of the same entity at the same time or purchase or own stock of the same entity at the same time, or as a result of the same public offering.

Effect on Other Agreements. This Amendment sets forth the Parties’ entire agreement regarding severance benefits available to Executive and supersedes any severance opportunity provided in the Offer Letter, the Amended and Restated Gentherm Incorporated Senior Level Performance Bonus Plan or any other agreement. For clarity, this Amendment does not supersede or modify any provision governing the treatment of Executive’s equity interests or rights to acquire equity interests following the termination of Executive’s employment. Except as expressly set forth in this Amendment, the Offer Letter remains unmodified, in full force and effect.

If any payment or benefit that Executive would otherwise receive pursuant to this Amendment (when considered together with any payment or benefit Executive would otherwise receive under any other agreement or practice) (collectively, a “Payment”) would (a) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (b) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall be equal to the Reduced Amount. The “Reduced Amount” shall be either: (y) the largest portion of the Payment that would result in no portion of the Payment (after reduction) being subject to the Excise Tax; or (z) the entire Payment, whichever amount after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate, net of the maximum reduction in federal
