Organization, Consolidation and Presentation of Financial Statements [Abstract]
Overview	Note 1 – Overview Gentherm Incorporated, a Michigan corporation, and its consolidated subsidiaries (“Gentherm”, “we”, “us”, “our” or the “Company”) is a global market leader of innovative thermal management and pneumatic comfort technologies. Our automotive products include Climate Control Seats (CCS®), Climate Control Interiors (CCI™), Lumbar and Massage Comfort Solutions, Valve Systems, and Climate and Comfort Electronics. We operate in locations aligned with our major customers’ product strategies to provide locally enhanced design, integration and production capabilities. Our medical products include patient temperature management systems that can be found in hospitals throughout the world. IME Acquisition On July 1, 2026, the Company completed its acquisition of Innovative Medical Equipment, LLC (“IME”). IME, headquartered in Beachwood, Ohio, is a provider of the ThermaZone® thermal therapy device. ThermaZone is a non-opioid thermal therapy solution designed to support pain management and recovery through controlled hot-and-cold therapy. The Company acquired all of the membership interests in IME for $34,000, net of cash and debt, and subject to customary adjustments related to IME’s net working capital as of the closing date. The purchase price may be increased after closing by up to $1,000 upon the achievement of a specified performance milestone. The transaction was funded through a combination of the Company’s existing cash balances and borrowings under the Revolving Credit Facility, as defined below. Modine Transaction On January 29, 2026, the Company, entered into definitive agreements to combine the Performance Technologies business (“Performance Technologies”) of Modine Manufacturing Co., a Wisconsin corporation (“Modine”), with the Company (the “Modine Transaction”). The Modine Transaction is structured as a Reverse Morris Trust transaction, where a wholly owned subsidiary of Modine (“SpinCo”), owning Performance Technologies, will be spun off to Modine shareholders (the “Distribution”) and simultaneously merged with a wholly owned subsidiary of the Company (the “Merger”). The transaction was valued at approximately $1,000,000 as of the date of signing, based on specified assumptions. Shareholders of the Company immediately prior to the Merger are expected to own approximately 60.0% of the combined company and Modine shareholders are expected to own approximately 40.0% of the combined company, on a fully diluted basis, without taking into account any overlapping shareholder ownership and subject to adjustment. Prior to and as a condition of, the Distribution, Modine will receive a cash distribution from SpinCo of $210,000, subject to adjustment for cash, working capital and indebtedness of SpinCo, and subject to decrease if additional shares of Common Stock will be issued to Modine shareholders to support the intended tax-free treatment of the Distribution to Modine shareholders for U.S. federal income tax purposes (the “SpinCo Cash Distribution”). The transaction is expected to close by early fourth quarter of 2026, subject to various closing conditions, including specified approvals by the Company’s shareholders, a customary IRS tax ruling and the satisfaction of other customary closing conditions. The Merger Agreement contains specified termination rights for the Company and Modine, including a right allowing the Company or Modine to terminate the Merger Agreement if the Merger has not been consummated on or prior to March 31, 2027 (which date may be extended to June 30, 2027 in the event that required regulatory approvals have not been received). Additionally, the Merger Agreement requires the Company to pay Modine a termination fee of $45,000 if the Merger Agreement is terminated under certain circumstances. In connection with the Merger Agreement, the Company, SpinCo and a financial institution executed a 364-day bridge loan facility commitment letter, pursuant to which such financial institution committed (i) to provide bridge financing of $290,000 to fund dividends, fees and expenses related to the transactions contemplated by the Merger Agreement (“Bridge Facility”) and (ii) to provide the Company a backstop of the Company’s credit agreement (“Backstop Commitment”). On February 24, 2026, the Company amended its credit agreement to permit the Modine Transaction, which terminated the Backstop Commitment. On June 29, 2026, SpinCo replaced the Bridge Facility with permanent financing by entering into a credit agreement, providing for a delayed-draw term loan facility with aggregate commitments of up to $250,000 (the "Senior Credit Facility"). Borrowings under the Senior Credit Facility are expected to be funded on the closing date of the Modine Transaction and used to fund the SpinCo Cash Distribution and to pay certain other amounts required under the Merger Agreement. During the three and six months ended June 30, 2026, the Company incurred $2,145 and $5,135, respectively, of fees associated with the Bridge Facility, Backstop Commitment and Senior Credit Facility. Such fees are recorded in Selling, general and administrative expenses. Basis of Presentation and Significant Accounting Policies The unaudited consolidated condensed financial statements included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to those rules and regulations. The information furnished in the consolidated condensed financial statements include all adjustments (consisting of only normal, recurring adjustments) considered necessary to present fairly the results of operations, financial position and cash flows of the Company. These financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. The operating results for interim periods are not necessarily indicative of results that may be expected for other interim periods or for the full year. In preparing these financial statements, management was required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. These estimates and assumptions are based on our historical experience, the terms of existing contracts, our evaluation of trends in the industry, information provided by our customers and suppliers and information available from other third-party sources, as appropriate. These estimates and assumptions are subject to an inherent degree of uncertainty and may change as new events occur and additional information is obtained. As a result, actual results may differ significantly from our estimates, and any such differences may be material to our financial statements. All amounts in these notes to the consolidated condensed financial statements are presented in thousands, except share and per share data. Principles of Consolidation The consolidated condensed financial statements include the accounts of the Company, its wholly owned subsidiaries and those entities in which it has a controlling financial interest. The Company evaluates its relationship with other entities for consolidation and to identify whether such entities are variable interest entities and to assess whether the Company is the primary beneficiary of such entities. Investments in affiliates in which Gentherm does not have control but does have the ability to exercise significant influence over operating and financial policies are accounted for under the equity method. When Gentherm does not have the ability to exercise significant influence (generally when ownership interest is less than 20%), investments in affiliates are measured at cost, less impairments, adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer. Revenue Recognition - payments to customers From time to time, the Company provides cash incentives to customers in exchange for new business awards. The Company evaluates the underlying economics of each amount of consideration payable to a customer to determine the proper accounting by understanding the reasons for the payment, the rights and obligations resulting from the payment, the nature of the promises in the contract, and other relevant facts and circumstances. When the Company concludes that the payment is incurred only if the new business is obtained and the Company expects to recover the amounts from the customer over the term of the new business arrangement, the Company recognizes these payments as an asset. The Company amortizes the asset as a reduction of revenue as products related to the payment are transferred to the customer, based on the total amount of products expected to be sold over the term of the arrangement (generally 5 to 10 years following start of production). The Company evaluates the amounts capitalized each reporting period for recoverability and recognizes a reduction of revenue for any amounts that are no longer expected to be recovered over the term of the business arrangement. Payments to customers that are not capitalized are recognized as a reduction to revenue at the time of the commitment to make such payments. As of June 30, 2026 and December 31, 2025, total capitalized payments to customers were $22,142 and $18,168, respectively. During the three and six months ended June 30, 2026, the Company recognized $541 and $975 as reductions of revenue due to amortization and write-off of previously capitalized payments. During the three and six months ended June 30, 2025, the Company recognized $208 and $1,044 as reductions of revenue due to amortization and write-off of previously capitalized payments. The Company had no other material contract assets or contract liabilities as of June 30, 2026. Loss on Sale of Land and Building, net In January 2025, we completed the sale of our former headquarters building in Northville, Michigan for cash proceeds of $3,740. As a result, the Company recognized a loss on sale of $2,311 during the six months ended June 30, 2025.
