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 developer, manufacturer and marketer of innovative thermal management technologies for a broad range of heating, cooling and temperature control applications, primarily for the automotive and medical industries and pneumatic comfort technologies for the automotive industry. Within the automotive industry, our products provide solutions for passenger climate comfort and convenience, lumbar and massage comfort solutions, valve system technologies, battery thermal management and cell connecting systems. Within the medical industry our products provide patient temperature management solutions. Our automotive products can be found on vehicles manufactured by nearly all the major automotive original equipment manufacturers (“OEMs”) operating in North America and Europe, and several major OEMs in Asia. We operate in locations aligned with our major customers’ product strategies to provide locally enhanced design, integration and production capabilities. The Company is also developing a number of new technologies and products that are expected to enable improvements to existing products and to create new product applications for existing and new markets. 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, 2021. The operating results for interim periods are not necessarily indicative of results that may be expected for any other interim period 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 outside sources, as appropriate. These estimates and assumptions are subject to an inherent degree of uncertainty. We are not presently aware of any events or circumstances that would require us to update such estimates and assumptions or revise the carrying value of our assets or liabilities. Our estimates may change, however, 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. 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 (“VIE”) 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. Variable Interest Entities The Company maintains an ownership interest in a VIE, Carrar Ltd. (“Carrar”). Carrar is a technology developer of advanced thermal management systems for the electric mobility market. The Company determined that Carrar is a VIE; however, the Company does not have a controlling financial interest or have the power to direct the activities that most significantly affect the economic performance of the investment. Therefore, the Company has concluded that it is not the primary beneficiary. Gentherm’s investment in Carrar is measured at cost, less impairments, adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer. The Carrar investment was $ 5,200 as of June 30, 2022 and December 31, 2021 , and is recorded in Other non-current assets in the consolidated condensed balance sheets. Revenue Recognition The Company has no material contract assets or contract liabilities as of June 30, 2022. The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if the benefits of those costs are expected to be realized for a period greater than one year . Total capitalized costs to obtain a contract were $ 1,772 and $ 1,946 as of June 30, 2022 and December 31, 2021 , respectively. These amounts are recorded in Other non-current assets and are being amortized into Product revenues over the expected production life of the applicable program.

Accounting Standards Update and Change in Accounting Principle [Abstract]
New Accounting Pronouncements	Note 2 – New Accounting Pronouncements Reference Rate Reform In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of Effects of Reference Rate Reform on Financial Reporting”. ASU 2020-04 provides practical expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The expedients and exceptions provided by the amendments in this update apply only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate or another reference rate expected to be discontinued as a result of reference rate reform. These amendments are not applicable to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022. In January 2021, the FASB subsequently issued ASU 2021-01, “Reference Rate Reform (Topic 848): Scope” to clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. ASU 2020-04 and ASU 2021-01 are effective as of March 12, 2020 through December 31, 2022 and may be applied retrospectively to contract modifications and hedging relationships from the beginning of an interim period that includes or is subsequent to March 12, 2020, or on a prospective basis to new modifications from any date within an interim period that includes or is subsequent to the date of the issuance of a final update, up to the date that financial statements are available to be issued. The adoption of this standard is not expected to have a material impact on the Company’s financial statements.

Restructuring and Related Activities [Abstract]
Restructuring	Note 3 – Restructuring Manufacturing Footprint Rationalization In September 2019, the Company committed to a restructuring plan (“Plan”) to improve the Company’s manufacturing productivity and rationalize its footprint. Under this Plan, the Company is relocating and consolidating certain automotive electronics manufacturing plants in North America and China. During 2021, the Company completed the closures and relocation of its automotive electronics manufacturing operations from Burlington, Canada to Celaya, Mexico and from Longgang, Shenzhen, China to Bantian, Shenzhen, China. As of June 30, 2022, the electronics manufacturing in Acuña, Mexico continues to transition to Celaya, Mexico. During the three and six months ended June 30, 2022 , the Company recognized restructuring expense of $ 0 and $ 50 , respectively, for employee separation costs and $ 97 and $ 198 , respectively, for other costs. During the three and six months ended June 30, 2021 , the Company recognized restructuring expense of $ 759 and $ 965 for employee separation costs, respectively, $ 97 and $ 192 for accelerated depreciation, respectively, and $ 488 and $ 652 for other costs, respectively. The Company has recorded approximately $ 10,353 of restructuring expenses since the inception of this program and as of June 30, 2022 , $ 538 remains accrued. Actions under the Plan are expected to be substantially completed by the end of 2022 and future expenses are expected to be less than $ 1,000 . Other Restructuring Activities As part of the Company’s continued efforts to optimize its cost structure, the Company has undertaken several discrete restructuring actions. During the three and six months ended June 30, 2022 , the Company recognized $ 277 and $ 307 , respectively, for other costs. During the three and six months ended June 30, 2021 , the Company recognized $ 747 and $ 1,073 , respectively, of employee separation costs. These restructuring expenses were primarily associated with restructuring actions focused on the rotation of our manufacturing footprint to best cost locations and the reduction of global overhead costs. Restructuring Expenses By Reporting Segment The following table summarizes restructuring expense for the three and six months ended June 30, 2022 and 2021 by reporting segment: Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Automotive $ 374 $ 1,075 $ 555 $ 1,866 Medical — — — — Corporate — 1,016 — 1,016 Total $ 374 $ 2,091 $ 555 $ 2,882 Restructuring Liability Restructuring liabilities are classified as Other current liabilities in the consolidated condensed balance sheets.

The Second Amended and Restated Credit Agreement amends and restates in its entirety the Amended and Restated Credit Agreement dated June 27, 2019, by and among Gentherm, certain of its direct and indirect subsidiaries, the lenders party thereto and the Agent. The Second Amended and Restated Credit Agreement provides for a $ 500,000 secured revolving credit facility (the “Revolving Credit Facility”) (a $ 25,000 increase from the revolving credit facility under the Amended and Restated Credit Agreement), with a $ 50,000 sublimit for swing line loans and a $ 15,000 sublimit for the issuance of standby letters of credit. Any amount of the facility utilized for swing line loans or letters of credit outstanding will reduce the amount available under the Second Amended and Restated Credit Agreement. The Company had no outstanding letters of credit issued as of June 30, 2022 and December 31, 2021. Subject to specified conditions, Gentherm can increase the Revolving Credit Facility or incur secured term loans in an aggregate amount of up to $ 200,000 . The Second Amended and Restated Credit Agreement extends the maturity of the Revolving Credit Facility from June 27, 2024 to June 10, 2027 . The outstanding principal and interest (of approximately $ 35,000 as of June 10, 2022) under the Amended and Restated Credit Agreement continued and remained obligations under the Second Amended and Restated Credit Agreement. The U.S. borrowers and guarantors participating in the Second Amended and Restated Credit Agreement also entered into a Second Amended and Restated Pledge and Security Agreement (the “Second Amended and Restated Security Agreement”). The Second Amended and Restated Security Agreement grants a security interest to the Agent in substantially all of the personal property of the Company and its U.S. subsidiaries designated as borrowers to secure their respective obligations under the Second Amended and Restated Security Agreement, including the stock and membership interests of specified subsidiaries (limited to 66 % of the stock in the case of certain non-U.S. subsidiaries). In addition to the security obligations, all obligations under the Second Amended and Restated Credit Agreement (including all obligations of any U.S. or non-U.S. loan party) are unconditionally guaranteed by certain of Gentherm’s domestic subsidiaries, and the German subsidiary borrowers and certain other foreign subsidiaries guarantee all obligations of the non-U.S. loan parties under the Second Amended and Restated Credit Agreement. The Second Amended and Restated Credit Agreement restricts, among other things, the amount of dividend payments the Company can make to shareholders. The Second Amended and Restated Credit Agreement contains covenants, that, among other things, (i) prohibit or limit the ability of the borrowers and any material subsidiary to incur additional indebtedness, create liens, pay dividends, make certain types of investments (including acquisitions), enter into certain types of transactions with affiliates, prepay other indebtedness, sell assets or enter into certain other transactions outside the ordinary course of business, and (ii) require that Gentherm maintain a minimum Consolidated Interest Coverage Ratio and a maximum Consolidated Net Leverage Ratio (based on consolidated EBITDA for the applicable trailing four fiscal quarters) as of the end of any fiscal quarter. The Second Amended and Restated Credit Agreement also contains customary events of default. As of June 30, 2022, the Company was in compliance with the terms of the Second Amended and Restated Credit Agreement. The Second Amended and Restated Credit Agreement additionally contains customary events of default. Upon the occurrence of an event of default, the amounts outstanding under the Revolving Credit Facility may be accelerated and may become immediately due and payable. Under the Second Amended and Restated Credit Agreement, U.S. Dollar denominated loans bear interest at either a base rate (“Base Rate Loans”) or Term SOFR rate (“Term SOFR Rate Loans”), plus a margin (“Applicable Rate”). The rate for Base Rate Loans is equal to the highest of the Federal Funds Rate plus 0.50 %, Bank of America’s prime rate, or the Term SOFR rate plus 1.00 %. The rate for Term SOFR Rate Loans denominated in U.S. Dollars is equal to the forward-looking Secured Overnight Financing Rate (“SOFR”) term rate administered by the CME with a term of one month. All loans denominated in a currency other than the U.S. Dollar must be Term SOFR Rate Loans. Interest is payable at least quarterly. Additionally, a commitment fee of between 0.175 % to 0.300 %, which will vary based on the Consolidated Net Leverage Ratio, as defined in the Second Amended and Restated Credit Agreement, is payable on the average daily unused amounts under the Revolving Credit Facility. The Applicable Rate varies based on the Consolidated Net Leverage Ratio reported by the Company. As long as the Company is not in default of the terms and conditions of the Second Amended and Restated Credit Agreement, the lowest and highest possible Applicable Rate is 1.125 % and 2.125 %, respectively, for Term SOFR Rate Loans and 0.125 % and 1.125 %, respectively, for Base Rate Loans. Borrowing availability is subject to, among other things, the Company’s compliance with the minimum Consolidated Interest Coverage Ratio and the maximum Consolidated Net Leverage Ratio as of the end of any fiscal quarter. Based upon consolidated EBITDA for the trailing four fiscal quarters calculated for purposes of the Consolidated Net Leverage Ratio, $357,017 remained available as of June 30, 2022 for additional borrowings under the Second Amended and Restated Credit Agreement subject to specified conditions that Gentherm currently satisfies. In connection with the Second Amended and Restated Credit Agreement, the Company incurred debt issuance costs of $ 1,417 , which have been capitalized and will be amortized into interest expense over the term of the credit facility. In addition, unamortized deferred debt issuance costs of $ 144 were written-off and recognized in Interest expense, net during three months ended June 30, 2022. DEG Vietnam Loan The Company also has a fixed interest rate loan with the German Investment Corporation (“DEG”), a subsidiary of KfW Banking Group, a Germany government-owned development bank. The fixed interest rate senior loan agreement with DEG was used to finance the construction and set up of the Vietnam production facility (“DEG Vietnam Loan”). The DEG Vietnam Loan is subject to semi-annual principal payments that began November 2017 and will end May 2023 . Under the terms of the DEG Vietnam Loan, the Company must maintain a minimum Enhanced Equity Ratio, as defined by the DEG Vietnam Loan agreement, based on the financial statements of Gentherm’s wholly owned subsidiary, Gentherm Vietnam Co. Ltd. As of June 30, 2022, the Company was in compliance with the terms of the DEG Vietnam Loan. The scheduled principal maturities of our debt as of June 30, 2022 were as follows: DEG U.S. Total 2022 $ 1,250 $ — $ 1,250 2023 1,250 — 1,250 2024 — — — 2025 — — — 2026 — — — 2027 — 35,000 35,000 Total $ 2,500 $ 35,000 $ 37,500

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 7 – Commitments and Contingencies Legal and other contingencies The Company may be subject to various legal actions and claims in the ordinary course of its business, including those arising out of breach of contracts, intellectual property rights, environmental matters, regulatory matters and employment-related matters. The Company establishes accruals for matters that it believes that losses are probable and can be reasonably estimated. Although it is not possible to predict with certainty the outcome of these matters, the Company is of the opinion that the ultimate resolution of these matters will not have a material adverse effect on its consolidated results of operations or financial position. Product Liability and Warranty Matters In the event that the Company’s products fail to perform as expected or result in alleged bodily injury or property damage, our products may subject us to warranty claims and product liability. If any of our products are or are alleged to be defective, we may be required to participate in a recall or other corrective action involving such products. The Company maintains liability insurance coverage at levels based on commercial norms and historical claims experience. The Company can provide no assurances that it will not experience material claims in the future or that it will not incur significant costs to defend such claims. The Company accrues warranty obligations for products sold based on management estimates of future failure rates and current claim cost experience, with support from the sales, engineering, quality and legal functions. Using historical information available to the Company, including claims already filed by customers, the warranty accrual is adjusted quarterly to reflect management’s best estimate of future claims. The following is a reconciliation of the changes in accrued warranty costs: Six Months Ended June 30, 2022 2021 Balance at the beginning of the period $ 1,916 $ 2,391 Warranty claims paid ( 623 ) ( 599 ) Warranty expense for products shipped during the current period 818 1,043 Adjustments to warranty estimates from prior periods ( 171 ) ( 314 ) Adjustments due to currency translation ( 41 ) ( 26 ) Balance at the end of the period $ 1,899 $ 2,495 Other matters Purchase commitments for materials, supplies, services and capital expenditures, as part of the normal course of business, are generally consistent from year to year. In addition, due to supply shortages of semiconductors, the Company has entered into agreements with various suppliers to reserve the right to purchase certain semiconductor chips over rolling periods of 12 - 24 months , with volume commitments determined based on our anticipated production requirements. As of June 30, 2022 , the Company’s total commitments for these semiconductor chip agreements was $ 40,378 . Such agreements provide the Company with priority access to semiconductor chips as they become available, however, these agreements do not guarantee that our suppliers will meet the timing and quantities requested by Gentherm. All other purchase commitments as of June 30, 2022 were immaterial.

Earnings Per Share [Abstract]
Earnings per Share	Note 8 – Earnings Per Share Basic earnings per share are computed by dividing net income by the weighted average number of shares of Common Stock outstanding during the period. The Company’s diluted earnings per share give effect to all potential shares of Common Stock outstanding during a period that do not have an anti-dilutive impact to the calculation. In computing the diluted earnings per share, the treasury stock method is used in determining the number of shares assumed to be issued from the exercise of Common Stock equivalents. The following table illustrates earnings per share and the weighted average shares outstanding used in calculating basic and diluted earnings per share: Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Net income $ 7,072 $ 24,791 $ 18,819 $ 57,700 Basic weighted average shares of Common Stock outstanding 33,119,085 33,100,230 33,077,029 33,025,432 Dilutive effect of stock options, restricted stock awards and restricted stock units 307,038 443,978 344,958 443,417 Diluted weighted average shares of Common Stock outstanding 33,426,123 33,544,208 33,421,987 33,468,849 Basic earnings per share $ 0.21 $ 0.75 $ 0.57 $ 1.75 Diluted earnings per share $ 0.21 $ 0.74 $ 0.56 $ 1.72 There were no shares excluded from the Company’s diluted earnings per share for the three and six months ended June 30, 2022 and 2021 on the basis that their inclusion would have an anti-dilutive impact on the calculation.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	Note 9 – Financial Instruments Derivative Financial Instruments The Company is exposed to various market risks including, but not limited to, changes in foreign currency exchange rates, changes in interest rates and price fluctuations of certain material commodities such as copper. Market risks for changes in interest rates relate primarily to its debt obligations under the Second Amended and Restated Credit Agreement. Foreign currency exchange risks are attributable to sales to foreign customers and purchases from foreign suppliers not denominated in a location’s functional currency, foreign plant operations, intercompany indebtedness, acquisitions denominated in foreign currencies, intercompany investments and include exposures to the Euro, Mexican Peso, Canadian Dollar, Hungarian Forint, North Macedonian Denar, Ukrainian Hryvnia, Japanese Yen, Chinese Renminbi, Korean Won and Vietnamese Dong. The Company regularly enters into derivative contracts with the objective of managing its financial and operational exposure arising from these risks by offsetting gains and losses on the underlying exposures with gains and losses on the financial instruments used to hedge them. The decision of whether and when to execute derivative financial instruments, along with the duration of the instrument, may vary from period to period depending on market conditions, the relative costs of the instruments and capacity to hedge. The duration is linked to the timing of the underlying exposure, with the connection between the two being regularly monitored. The Company does not enter into derivative financial instruments for speculative or trading purposes. Some derivative contracts do not qualify for hedge accounting; for other derivative contracts, we elect to not apply hedge accounting. The Company’s designated hedging relationships are formally documented at the inception of the hedge, and hedges must be highly effective in offsetting changes to future cash flows on hedged transactions both at the inception of a hedge and on an ongoing basis to be designated for hedge accounting treatment. For derivative contracts which can be classified as a cash flow hedge, the effective portion of the change in the fair value of the derivative is recorded to Accumulated other comprehensive loss in the consolidated condensed balance sheets. When the underlying hedge transaction is realized, the gain or loss included in Accumulated other comprehensive loss is recorded in earnings in the consolidated condensed statements of income on the same line as the gain or loss on the hedged item attributable to the hedged risk. The Company records the ineffective portion of designated foreign currency and copper commodity hedging instruments, if any, to cost of sales in the consolidated condensed statements of income. Cash flows associated with derivatives are reported in net cash (used in) provided by operating activities in the Company’s consolidated condensed statements of cash flows. The Company uses an income approach to value derivative instruments, analyzing quoted market prices to calculate the forward values and then discounting such forward values to the present value using benchmark rates at commonly quoted intervals for the instrument’s full term. During the three months ended June 30, 2022, the Company entered into a floating-to-fixed interest rate swap agreement with a notional amount of $ 100,000 . This interest rate swap is an undesignated hedge of the Company’s exposure to interest payment fluctuations on a portion of the expected Credit Facility borrowings to be drawn for the acquisitions of Alfmeier and Dacheng. See Note 15, “Subsequent Events,” for information about the Company’s acquisition activities. The periodic changes in fair value is recognized in Interest expense, net. During the three months ended June 30, 2022, the Company entered into forward contracts with a notional amount of $ 128,319 to hedge the foreign currency risk associated with the forecasted purchase of Alfmeier. These forward contracts are not designated as hedging instruments. The periodic changes in fair value is recognized in Foreign currency gain (loss). Information related to the recurring fair value measurement of derivative instruments in our consolidated condensed balance sheet as of June 30, 2022 is as follows: Asset Derivatives Liability Derivatives Fair Value Notional Amount Balance Sheet Fair Balance Sheet Fair Net Asset/ Derivatives Designated as Cash Flow Hedges Foreign currency derivatives Level 2 $ 14,075 Other current assets $ 588 Other current liabilities $ — $ 588 Derivatives Not Designated as Hedging Instruments Foreign currency derivatives Level 2 $ 128,319 Other current assets $ 1,403 Other current liabilities $ 921 $ 482 Interest rate contracts Level 2 $ 100,000 Other current assets $ — Other current liabilities $ 693 $ 693 Information related to the recurring fair value measurement of derivative instruments in our consolidated condensed balance sheet as of December 31, 2021 is as follows: Asset Derivatives Liability Derivatives Fair Value Notional Amount Balance Sheet Fair Balance Sheet Fair Net Asset/ Derivatives Designated as Cash Flow Hedges Foreign currency derivatives Level 2 $ 13,974 Other current assets $ 294 Other current liabilities $ — $ 294 Commodity hedges Level 2 $ 309 Other current assets $ 6 Other current liabilities $ — $ 6 Information relating to the effect of derivative instruments on our consolidated condensed statements of income and the consolidated condensed statements of comprehensive income is as follows: Three Months Ended June 30, Six Months Ended June 30, Location 2022 2021 2022 2021 Derivatives Designated as Cash Flow Hedges Foreign currency derivatives Cost of sales – income $ 333 $ 529 $ 486 $ 1,007 Other comprehensive (loss) income ( 316 ) ( 62 ) 294 ( 729 ) Total foreign currency derivatives $ 17 $ 467 $ 780 $ 278 Commodity derivatives Cost of sales – income $ — $ — $ 19 $ — Other comprehensive loss — — ( 6 ) — Total commodity derivatives $ — $ — $ 13 $ — Derivatives Not Designated as Hedging Instruments Foreign currency derivatives Foreign currency gain (loss) $ 482 $ — $ 482 $ — Total foreign currency derivatives $ 482 $ — $ 482 $ — Interest rate contracts Interest expense, net $ ( 693 ) $ — $ ( 693 ) $ — Total interest rate derivatives $ ( 693 ) $ — $ ( 693 ) $ — Accounts Receivable Factoring The Company is party to a receivable factoring agreement with HSBC Bank USA, National Association.

As of June 30, 2022 , there were no outstanding receivables transferred under the receivable factoring agreement and our availability under the receivables factoring agreement was $ 32,431 .

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 10 – Fair Value Measurements Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value measurements are based on one or more of the following three valuation techniques: Market : This approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. Income : This approach uses valuation techniques to convert future amounts to a single present value amount based on current market expectations. Cost : This approach is based on the amount that would be required to replace the service capacity of an asset (replacement cost). The Company uses the following fair value hierarchy to measure fair value into three broad levels, which are described below: Level 1 : Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs. Level 2 : Inputs, other than quoted market prices included in Level 1, that are observable either directly or indirectly for the asset or liability. Level 3 : Unobservable inputs that are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs. Items Measured at Fair Value on a Recurring Basis Except for derivative instruments (see Note 9) and pension plan assets, the Company had no material financial assets and liabilities that were carried at fair value at June 30, 2022 and December 31, 2021. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible and also considers counterparty credit risk in its assessment of fair value. Items Measured at Fair Value on a Nonrecurring Basis The Company measures certain assets and liabilities at fair value on a non-recurring basis. As these nonrecurring fair value measurements are generally determined using unobservable inputs, these fair value measurements are classified within Level 3 of the fair value hierarchy. As of June 30, 2022 and December 31, 2021 , there were no significant assets or liabilities measured at fair value on a non-recurring basis. Items Not Carried at Fair Value The Company uses an income valuation technique to measure the fair values of its debt instruments by converting amounts of future cash flows to a single present value amount using rates based on current market expectations (Level 2 inputs). As of June 30, 2022, and December 31, 2021, the carrying values of the indebtedness under the Company’s Second Amended and Restated Credit Agreement were not materially different than the estimated fair values because the interest rates on variable rate debt approximated rates currently available to the Company (see Note 6). Discount rates used to measure the fair value of Gentherm’s DEG Vietnam Loan are based on quoted swap rates. As of June 30, 2022 , the carrying value of the DEG Vietnam Loan was $ 2,500 as compared to an estimated fair value of $ 2,490 . As of December 31, 2021 , the carrying value of the DEG Vietnam Loan was $ 3,750 as compared to an estimated fair value of $ 3,778 .

Income Taxes

Income Taxes	6 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Note 13 – Income Taxes At the end of each interim period, the Company makes its best estimate of the annual expected effective income tax rate and applies that rate to its ordinary year-to-date earnings or loss. The income tax provision or benefit related to unusual or infrequent items, if applicable, that will be separately reported or reported net of their related tax effects are individually computed and recognized in the interim period in which those items occur. In addition, the effect of changes in enacted tax laws or rates, tax status, judgment on the realizability of a beginning-of-the-year deferred tax asset in future years or income tax contingencies is recognized in the interim period in which the change occurs. The computation of the annual expected effective income tax rate at each interim period requires certain estimates and assumptions including, but not limited to, the expected pre-tax income (or loss) for the year, projections of the proportion of income (and/or loss) earned and taxed in respective jurisdictions, permanent and temporary differences, and the likelihood of the realizability of deferred tax assets generated in the current year. Jurisdictions with a projected loss for the year for which no tax benefit can be recognized due to a valuation allowance are excluded from the estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter, based upon the composition and timing of actual earnings compared to annual projections. The estimates used to compute the provision or benefit for income taxes may change as new events occur, additional information is obtained or as our tax environment changes. To the extent that the expected annual effective income tax rate changes, the effect of the change on prior interim periods is included in the income tax provision in the period in which the change in estimate occurs. A summary of the provision for income taxes and the corresponding effective tax rate for the three and six months ended June 30, 2022 and 2021, is shown below: Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Income tax expense $ 3,919 $ 5,748 $ 8,214 $ 13,313 Earnings before income tax $ 10,991 $ 30,539 $ 27,033 $ 71,013 Effective tax rate 35.7 % 18.8 % 30.4 % 18.7 % Income tax expense was $ 3,919 for the three months ended June 30, 2022 on earnings before income tax of $ 10,991 , representing an effective tax rate of 35.7 %. The effective tax rate differed from the U.S. Federal statutory rate of 21.0 % primarily due to the impact of income taxes on foreign earnings taxed at rates varying from the U.S. statutory rate, the unfavorable impact of the global intangible low-tax income (“GILTI”), and the quarterly accrual for uncertain tax positions partially offset by the impact of certain favorable tax effects on equity vesting . Income tax expense was $ 5,748 for the three months ended June 30, 2021 on earnings before income tax of $ 30,539 , representing an effective tax rate of 18.8 %. The effective tax rate differed from the U.S. Federal statutory rate of 21 % primarily due to certain favorable tax effect on equity vesting and intercompany transactions in the second quarter of 2021, partially offset by unfavorable impact of GILTI . Income tax expense was $ 8,214 for the six months ended June 30, 2022 on earnings before income tax of $ 27,033 , representing an effective tax rate of 30.4 %. The effective tax rate differed from the U.S. Federal statutory rate of 21 % primarily due to the impact of income taxes on foreign earnings taxed at rates varying from the U.S. statutory rate, the unfavorable impact of GILTI, and the quarterly accrual for uncertain tax positions partially offset by the impact of certain favorable tax effects of equity vesting. Income tax expense was $ 13,313 for the six months ended June 30, 2021 on earnings before income tax of $ 71,013 , representing an effective tax rate of 18.7 %. The effective tax rate differed from the U.S. Federal statutory rate of 21 % primarily due to certain favorable tax effect on equity vesting and intercompany transactions in 2021, partially offset by the unfavorable impact of GILTI.

Segment Reporting [Abstract]
Segment Reporting	Note 14 – Segment Reporting Segment information is used by management for making strategic operating decisions for the Company. Management evaluates the performance of the Company’s segments based primarily on operating income or loss. The Company’s reportable segments are as follows: • Automotive – this segment represents the design, development, manufacturing and sales of automotive climate comfort systems, automotive cable systems, battery performance solutions, and automotive electronic and software systems. • Medical – this segment represents the results from our patient temperature management business within the medical industry. The Corporate category includes unallocated costs related to our corporate headquarter activities, including selling, general and administrative costs and acquisition transaction costs, which do not meet the requirements for being classified as an operating segment.

Subsequent Events [Abstract]
Subsequent Events	Note 15 – Subsequent Events On May 4, 2022, the Company entered into a definitive purchase agreement to acquire the automotive business of Alfmeier Präzision SE (“Alfmeier”), a global leader in automotive lumbar and massage comfort solutions and a leading provider of advanced valve systems technology, integrated electronics and software. Also on May 4, 2022, the Company entered into a put and call option agreement with one of the owners of Alfmeier for the real property in Germany on which Alfmeier’s headquarters is located. Pursuant to this agreement, the seller had a put to sell the headquarters to the Company and the Company had an option to purchase the headquarters post-closing of the acquisition of Alfmeier. Prior to the closing of the acquisition, Alfmeier and certain of its subsidiaries completed a series of carve-out transactions such that Alfmeier’s industrial and non-automotive business would not be acquired by the Company. On July 29, 2022, the Company completed the acquisition of Alfmeier through the acquisition of all shares in Alfmeier for a total purchase price of € 181,500 (approximately $ 184,871 at foreign exchange rates as of such date), net of cash and cash-like items and debt and debt-like items, and subject to customary adjustments related to Alfmeier’s net working capital as of the closing. The Alfmeier purchase price was increased by € 4,000 (approximately $ 4,074 at foreign exchange rates as of such date) at closing as a result of the resolution of certain Alfmeier tax matters prior to closing. Also, on July 29, 2022, the Company completed the acquisition of Alfmeier’s headquarters for a purchase price of € 10,500 (approximately $ 10,730 at foreign exchange rates as of such date). The transactions were funded through a combination of the Company’s existing cash balances and borrowings under the Revolving Credit Facility. On July 13, 2022, the Company completed the acquisition of Jiangmen Dacheng Medical Equipment Co. Ltd (“Dacheng”) and its wholly owned subsidiary, IOB Medical, Inc. (“IOB”). Dacheng, a privately held company headquartered in Jiangmen, Guangdong Province, China, is a manufacturer of medical materials and medical equipment, including patient temperature management solutions, for numerous local and international customers. The acquisition provides Gentherm Medical a local presence in China’s high-growth market for patient warming devices and other medical device products, while also expanding overall manufacturing capacity to include a low-cost manufacturing site. The Company acquired all shares in Dacheng for $ 34,300 , net of cash and debt, and subject to customary adjustments related to Dacheng’s net working capital as of the closing. The purchase price may be increased by up to $ 3,000 post-closing upon the achievement of certain milestones. Also, as part of the transaction but not the purchase price or net working capital, IOB retained the obligation to satisfy an existing $ 2,700 consulting fee for work performed on IOB’s behalf. The transaction was funded through a combination of the Company’s existing cash balances and borrowings under the Revolving Credit Facility.

Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	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, 2021. The operating results for interim periods are not necessarily indicative of results that may be expected for any other interim period 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 outside sources, as appropriate. These estimates and assumptions are subject to an inherent degree of uncertainty. We are not presently aware of any events or circumstances that would require us to update such estimates and assumptions or revise the carrying value of our assets or liabilities. Our estimates may change, however, 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.
Principles of Consolidation	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 (“VIE”) 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.
Variable Interest Entities	Variable Interest Entities The Company maintains an ownership interest in a VIE, Carrar Ltd. (“Carrar”). Carrar is a technology developer of advanced thermal management systems for the electric mobility market. The Company determined that Carrar is a VIE; however, the Company does not have a controlling financial interest or have the power to direct the activities that most significantly affect the economic performance of the investment. Therefore, the Company has concluded that it is not the primary beneficiary. Gentherm’s investment in Carrar is measured at cost, less impairments, adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer. The Carrar investment was $ 5,200 as of June 30, 2022 and December 31, 2021 , and is recorded in Other non-current assets in the consolidated condensed balance sheets.
Revenue Recognition	Revenue Recognition The Company has no material contract assets or contract liabilities as of June 30, 2022. The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if the benefits of those costs are expected to be realized for a period greater than one year . Total capitalized costs to obtain a contract were $ 1,772 and $ 1,946 as of June 30, 2022 and December 31, 2021 , respectively. These amounts are recorded in Other non-current assets and are being amortized into Product revenues over the expected production life of the applicable program.
Reference Rate Reform	Reference Rate Reform In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of Effects of Reference Rate Reform on Financial Reporting”. ASU 2020-04 provides practical expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The expedients and exceptions provided by the amendments in this update apply only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate or another reference rate expected to be discontinued as a result of reference rate reform. These amendments are not applicable to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022. In January 2021, the FASB subsequently issued ASU 2021-01, “Reference Rate Reform (Topic 848): Scope” to clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. ASU 2020-04 and ASU 2021-01 are effective as of March 12, 2020 through December 31, 2022 and may be applied retrospectively to contract modifications and hedging relationships from the beginning of an interim period that includes or is subsequent to March 12, 2020, or on a prospective basis to new modifications from any date within an interim period that includes or is subsequent to the date of the issuance of a final update, up to the date that financial statements are available to be issued. The adoption of this standard is not expected to have a material impact on the Company’s financial statements.
