Summary of Significant Accounting Policies (Policies)	12 Months Ended
Dec. 31, 2025
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the consolidated financial statements and the reported amounts of expenses during the reporting period. Actual results could differ materially from those estimates and assumptions. On an ongoing basis, management evaluates its estimates assumptions, including those related to (i) the collectability of accounts receivable; (ii) write-down for excess and obsolete inventories; (iii) valuation of acquired intangibles and goodwill; (iv) warranty obligations; (v) the value assigned to and estimated useful lives of long-lived assets; (vi) the realization of tax assets and estimates of tax liabilities and tax reserves; (vii) amounts recorded in connection with acquisitions; (viii) recoverability of intangible assets and goodwill; (ix) the recognition and disclosure of fair value of debt instruments and contingent liabilities; (x) the computation of share-based compensation; (xi) accrued expenses; and (xii) the recognition of revenue based on a cost-to-cost measure of progress for certain engineering services contracts. These estimates are based on historical data and experience, as well as various other factors that management believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. The Company engages third-party valuation specialists to assist with estimates related to the valuation of certain financial instruments and assets acquired in connection with acquisitions as well as the valuation of reporting units and certain intangible assets in connection with quantitative impairment analyses over goodwill and intangible assets. Such estimates often require the selection of appropriate valuation methodologies and models, and significant judgment in evaluating ranges of assumptions and financial inputs. Actual results may differ from those estimates under different assumptions or circumstances.
Foreign Currency	Foreign Currency Certain of the Company’s self-sustaining foreign subsidiaries use their respective local currency as their functional currency. Assets and liabilities for these subsidiaries have been translated into U.S. dollars at the exchange rates prevailing at the end of the period and results of operations at the average exchange rates for the period. Unrealized exchange gains and losses arising from the translation of the financial statements of our non-U.S. functional currency operations are accumulated in the cumulative translation adjustments account in accumulated other comprehensive loss. For those foreign subsidiaries where the U.S. dollar is the functional currency, all foreign currency-denominated accounts are remeasured into U.S. dollars. Unrealized exchange gains and losses arising from remeasurements of foreign currency-denominated assets and liabilities are included within Other income (expense), net in the consolidated statements of operations and comprehensive loss. Gains and losses arising from international intercompany transactions that are of a long-term investment nature are reported in the same manner as translation gains and losses. Realized exchange gains and losses are included in net income for the periods presented.
Forward Exchange Contracts	Forward Exchange Contracts The Company’s forward exchange contracts, which are used to hedge anticipated U.S. dollar denominated sales and purchases as well as other foreign currency denominated sales and purchases such as Canadian Dollar, Euro and Great British Pound do not qualify for hedge accounting and are recognized at fair value. Any change in the fair value of these contracts is reflected as part of Other income (expense), net in the consolidated statement of operations.
Consolidation	Consolidation The consolidated financial statements comprise the financial statements of the Company, its wholly owned subsidiaries, and subsidiaries that it controls due to ownership of a majority voting interest. Subsidiaries are fully consolidated from the date of acquisition, being the date on which the Company obtains control, and continue to be consolidated until the date when such control ceases. All significant intercompany accounts and transactions are eliminated in consolidation. The Company recognizes noncontrolling interest related to its less-than-wholly-owned subsidiary as equity in the consolidated financial statements separate from the parent entity’s equity. The net loss attributable to noncontrolling interest is included in net loss in the consolidated statements of operations and comprehensive loss.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents are defined as short-term, highly liquid investments with original maturities of 90 days or less at the date of purchase. As of December 31, 2025 and 2024, cash and cash equivalents consisted of money market funds and cash deposits that were held by reputable financial institutions in local jurisdictions of the Company’s subsidiaries including primarily the United States, Austria, Canada, China, Germany, Great Britain and Switzerland denominated in U.S. dollars and local currency.
Restricted Cash	Restricted Cash The Company’s restricted cash consists of cash that the Company is contractually obligated to maintain in accordance with the terms of its Wells Fargo Bank revolving line of credit agreement.
Accounts Receivable	Accounts Receivable Accounts receivable consist of amounts due primarily from customers for product sales and engineering services agreements. Accounts receivable are recorded at the invoiced amount and do not bear interest. The Company accounts for potential losses in accounts receivable utilizing the allowance method. The Company closely monitors outstanding accounts receivable and considers its knowledge of customers, historical losses, and current and expected economic conditions in establishing the allowance for doubtful accounts. The Company wrote off $1,831 of accounts receivable, which was fully reserved under the allowance for doubtful accounts in the prior years, for the year ended December 31, 2025. The Company did not have any write-offs in any other periods presented.
Concentration of Credit Risk	Concentration of Credit Risk The Company deposits its cash with large financial institutions. At times, the Company’s cash balances with individual banking institutions will exceed the limits insured by the FDIC, however, the Company has not experienced any losses on such deposits. The Company extends credit to its customers based upon an evaluation of the customers’ financial condition and credit history and generally does not require collateral. Credit losses, if any estimated, are provided for in the consolidated financial statements and consistently have been within management’s expectations. See Note 15 — Revenue — Concentrations.
Inventory	Inventory The Company values inventories at the lower of cost or net realizable value on a first-in, first-out basis. Cost is computed using standard cost, which approximates actual cost, on a first-in, first-out basis. Inventories are reduced for write-downs based on periodic reviews for evidence of slow-moving or obsolete parts. The write-down is based on the comparison between inventory on hand and forecasted customer demand for each specific product. Once written down, inventory write-downs are not reversed until the inventory is sold or scrapped. Inventory write-downs are also established when conditions indicate the net realizable value is less than cost due to physical deterioration, technological obsolescence, changes in price level or other causes. All inventory provisions are recorded to cost of goods sold in the consolidated statement of operations.
Property and Equipment, net	Property and Equipment, net The Company’s property and equipment primarily consist of lab equipment, production tooling and masks, equipment, furniture and fixtures, leasehold improvements, and computer hardware and software. Property and equipment are recorded at cost less accumulated depreciation. Depreciation is calculated using the straight-line method based on the estimated useful lives of between three and seven years and for leasehold improvements the lesser of the remaining lease term or useful life. Major improvements are capitalized while routine repairs and maintenance are charged to expense when incurred. Production masks with discernible future benefits, namely that they will be used to manufacture products to service customer demand, are capitalized and amortized over the estimated useful life of four years. Production masks being used for research and development or testing do not meet the criteria for capitalization and are expensed as research and development costs. The Company recorded $376 of impairment charges related to certain software licenses as part of its 2025 Restructuring Plan.
Business Combinations	Business Combinations The Company accounts for its business acquisitions under the ASC Topic 805, Business Combinations guidance for business combinations. The total cost of acquisitions is allocated to the underlying identifiable net assets based on their respective estimated fair values. Determining the fair value of assets acquired and liabilities assumed requires management’s judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash inflows and outflows, discount rates, asset lives and market multiples, among other items.
Intangible Assets, net	Intangible Assets, net The Company’s intangible assets include intangible assets acquired from business combinations, intellectual property (“IP”) and software licensed from third parties. The majority of the intangible assets have finite lives, except for those related to in-progress research and development (“IPR&D”), and are amortized over a period of two to twelve years, on a straight-line basis, which approximates the pattern in which economic benefits of these assets are expected to be utilized. IPR&D is considered to have indefinite life until the abandonment or completion of the associated research and development efforts. If the development is abandoned in the future, these assets will be expensed in the period of abandonment. If and when the development activities are completed, IPR&D assets will be reclassified to developed technology, management will make a determination of the useful lives and methods of amortization of these assets.
Goodwill	Goodwill Goodwill represents the excess of the fair value of purchase consideration of an acquired business over the fair value of the identifiable net assets acquired. Goodwill is not amortized but is tested for impairment at a reporting unit level on an annual basis on October 1, or more frequently if circumstances change or an event occurs that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Significant judgment may be required when goodwill is assessed for impairment. Qualitative factors may be assessed to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount. If the assessment of all relevant qualitative factors indicates that it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, a quantitative goodwill impairment test is not necessary. These qualitative factors may include, but are not limited to, a significant change in the macroeconomic and business climate, medium to long-term revenue forecasts per industry trend and/or product launch timeline, operating performance indicators, adequacy of capital level to support ongoing business needs, and other factors. If the assessment of all relevant qualitative factors indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company will perform a quantitative goodwill impairment test. The quantitative impairment test for goodwill consists of a comparison of the fair value of a reporting unit with its carrying value, including the goodwill allocated to that reporting unit. If the carrying value of a reporting unit exceeds its fair value, the Company will recognize an impairment loss equal to the amount of the excess, limited to the amount of goodwill allocated to that reporting unit. Application of the impairment test requires judgment, including the identification of reporting units, assignment of assets and liabilities to reporting units and the determination of fair value of each reporting unit. For the year ended December 31, 2025, the Company performed a quantitative analysis over its two reporting units on October 1 using a combination of the income and market valuation approaches. The fair value of both reporting units exceeded their carrying values. For the years ended December 31, 2024 and 2023, the Company performed a qualitative analysis over its two reporting units on October 1 and concluded that it was not more likely than not that the fair value of the reporting units were less than their carrying amount. As a result, the Company did not record any impairment to goodwill for the years ended December 31, 2025, 2024 and 2023.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company reviews its long-lived assets, consisting of property and equipment, right-of-use assets and intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company regularly reviews its operating performance for indicators of impairment. Factors considered important that could trigger an impairment review include a significant underperformance relative to expected historical or projected future operating results, or a significant change in the manner of the use of the assets. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset (or asset group) to estimated undiscounted future cash flows expected to be generated by the asset (or asset group). If the carrying amount of an asset (or asset group) exceeds its estimated undiscounted future cash flows, an impairment charge is recognized to the extent the fair value is less than the carrying value. The Company recorded $3,260 of impairment charges related to certain software licenses as part of its 2025 Restructuring Plan. The Company recorded $998 of impairment charges related to certain property and equipment and right-of-use assets for the year ended December 31, 2024 as part of its 2024 Restructuring Plan initiative that commenced in August 2024 (see Note 4 — Restructuring Costs). As a result, all pre-tax charges related to such initiatives are separately reflected in Restructuring costs in the consolidated statement of operations. The Company did not record any impairment to long-lived assets for the years ended December 31, 2023.
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between willing, able and knowledgeable market participants at the measurement date. Fair value measurements are not adjusted for transaction costs. In addition, a three-tiered hierarchy for inputs is used in management’s determination of fair value of financial instruments that emphasizes the use of observable inputs over the use of unobservable inputs by requiring that the observable inputs be used when available. Observable inputs are market participant assumptions based on market data obtained from sources independent of the Company. Unobservable inputs are the reporting entity’s own assumptions about market participants based on the best information available under the circumstances. In assessing the appropriateness of using observable inputs in making its fair value determinations, the Company considers whether the market for a particular security is “active” or not based on all the relevant facts and circumstances. Valuation service providers typically obtain data about market transactions and other key valuation model inputs from multiple sources and, through the use of widely accepted valuation models, provide a single fair value measurement for individual securities for which a fair value has been requested under the terms of service agreements. The inputs used by the valuation service providers include, but are not limited to, market prices from recently completed transactions and transactions of comparable securities, interest rate yield curves, credit spreads, currency rates and other market observable information, as applicable. The valuation models consider, among other things, market observable information as of the measurement date as well as the specific attributes of the security being valued including its term, interest rate, credit rating, industry sector and, when applicable, collateral quality and other issue or issuer specific information. When market transactions or other market observable data is limited, the extent to which judgment is applied in determining fair value is greatly increased. As a basis for considering such assumptions, a three-tier value hierarchy is used in management’s determination of fair value based on the reliability and observability of inputs as follows: Level 1 — Valuations are based on unadjusted quoted prices in active markets that the Company has the ability to access for identical, unrestricted assets and do not involve any meaningful degree of judgment. An active market is defined as a market where transactions for the financial instrument occur with sufficient frequency and volume to provide pricing information on an ongoing basis; Level 2 — Valuations are based on direct and indirect observable inputs other than quoted market prices included in Level 1. Level 2 inputs include quoted prices for similar assets in active markets and inputs other than quoted prices that are observable for the asset, such as the terms of the security and market-based inputs; and Level 3 — Valuations are based on techniques that use significant inputs that are unobservable. The valuation of Level 3 assets and liabilities requires the greatest degree of judgment. These measurements may be made under circumstances in which there is little, if any, market activity for the asset or liability. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment. In making the assessment, the Company considers factors specific to the asset. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement is classified is determined based on the lowest level input that is significant to the fair value measurement in its entirety. See Note 11 — Contingent and Earn-Out Liabilities and Note 12 — Fair Value Measurements for additional information. The Company’s fair value measurements in each reporting period include cash equivalents, debt instruments, share-based awards, contingent considerations and earn-out liabilities. The Company’s financial instruments of accounts receivable, accounts payable and accrued expenses are stated at their carrying value, which approximates fair value due to the short time to the expected receipt or payment date. The Company continues to remeasure its contingent considerations and earn-out liabilities associated with business combinations using Level 3 fair value measurements.
Warrant Liability	Warrant Liability The Company accounted for the Public Warrants and the Private Warrants, which were issued on June 10, 2021 in connection with the Transaction (as defined below), in accordance with ASC 815-40, Derivatives and Hedging—Contracts in Entity’s Own Equity (“ASC 815”), under which the Warrants do not meet the criteria for equity classification and must be recorded as liabilities. As the Warrants did not meet the definition of a derivative as contemplated in ASC 815, the warrants were measured at fair value at inception and at each reporting date in accordance with ASC 820, Fair Value Measurement, with changes in fair value recognized as a component of Other income (expense), net on the consolidated statement of operations. During the year ended December 31, 2023, indie completed the exchange of the Warrants, which eliminated the need for future remeasurement of the warrant liabilities. See Note 1 - Nature of the Business and Basis of Presentation - Warrant Exchange for further information.
Segment Information	Segment Information Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The chief operating decision maker (“CODM”) is the Chief Executive Officer. The Company has multiple business activities and are managed and held accountable for operations, operating results and plans for levels or components below the consolidated unit level by individual segment managers. However, discrete financial information is not reviewed by the CODM as the operating results of the Company are reviewed by the CODM only on a consolidated basis. Accordingly, the Company has one operating segment, and therefore, one reportable segment.
Revenue	Revenue Revenue is primarily derived from the design and sale of semiconductor solutions. Revenue is recognized within the scope of ASC 606, Revenue from Contracts with Customers. The Company recognizes product revenue in the consolidated statement of operations when it satisfies performance obligations under the terms of its contracts and upon transfer of control at a point in time when title transfers either upon shipment to or receipt by the customer as determined by the contractual shipping terms of the contract, net of accruals for estimated sales returns and allowances. To date, total returns and allowances issued by the Company has been de minimis. Sales and other taxes the Company collects, if any, are excluded from revenue. Product revenue arrangements do not contain significant financing components. The Company generally offers a limited warranty to customers covering a period of twelve months which obligates the Company to repair or replace manufacturing defective products. The warranty is not sold separately and does not represent a separate performance obligation. Therefore, such warranties are accounted for under ASC 460, Guarantees, and the estimated costs of warranty claims are accrued as cost of goods sold in the period the related revenue is recorded. Infrequently, the Company offers an extended limited warranty to customers for certain products. The Company accrues for known warranty and indemnification issues if a loss is probable and can be reasonably estimated. As of December 31, 2025, total warranty liability is not material. Engineering services contracts with customers typically contain only one distinct performance obligation, which is primarily design services for integrated circuits (“ICs”) based on agreed upon specifications. Engineering services contracts typically also include the purchase, at the customer’s option, of the designed products at agreed upon prices subsequent to completion of the design services. The Company has determined that the option to purchase these products is not a material right and has not allocated transaction price to this provision. For these engineering services arrangements, revenue is recognized over time as services are provided based on the terms of the contract on an input basis, using costs incurred as the measure of progress and is recorded as contract revenue in the consolidated statement of operations. The costs incurred represent the most reliable measure of transfer of control to the customer. Revenue is deferred for amounts billed or received prior to delivery of the services. Practical Expedients and Elections ASC 606 requires disclosure of the aggregate amount of transaction price that is allocated to performance obligations that have not yet been satisfied as of the reporting periods presented. The guidance provides certain practical expedients that limit this requirement and, therefore, disclosure of the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which revenue is recognized at the amount to which the Company has the right to invoice for services performed is not provided. The Company has elected not to disclose the aggregate amount of transaction prices associated with unsatisfied or partially unsatisfied performance obligations for contracts where these criteria are met. The Company’s policy is to capitalize any incremental costs incurred to obtain a customer contract, only to the extent that the benefit associated with the costs is expected to be longer than one year. Capitalizable contract costs were not significant as of both December 31, 2025 and 2024 and accordingly, no costs have been capitalized. The Company accounts for shipping and handling activities related to contracts with customers as costs to fulfill the promise to transfer the associated products. When shipping and handling costs are incurred after a customer obtains control of the products, the Company has elected to account for these as costs to fulfill the promise and not as a separate performance obligation. Shipping and handling costs associated with the distribution of products to customers are insignificant, but if incurred, are recorded in cost of goods sold generally when the related product is shipped to the customer. Upon adoption of ASC 842, Leases, the Company elected the package of practical expedients permitted under the transition guidance, which does not require reassessment of prior conclusions related to contracts containing a lease, lease classification and initial direct lease costs. Further, the Company elected to exclude short-term leases (term of 12 months or less) from the balance sheet presentation and accounted for non-lease and lease components in a contract as a single lease for certain asset classes.
Cost of Goods Sold	Cost of Goods Sold Cost of goods sold includes cost of materials and contract manufacturing services, including semiconductor wafers processed by third-party foundries, costs associated with packaging, assembly, testing and shipping products. In addition, cost of goods sold includes the costs of personnel, certain royalties for embedded intellectual property, production tooling used in the manufacturing process, logistics, warranty, and amortization of production mask costs. Cost of goods sold also include amortization of certain intangible assets acquired through business combinations. In addition to generating revenues from product shipments, the Company recognizes revenues related to certain engineering services contracts which help offset the costs of developing ICs for customers. The costs associated with fulfilling these contracts are expensed as incurred as research and development in the period incurred.
Research and Development Expense	Research and Development Expenses Research and development expenses consist of costs incurred in performing product design and development activities including employee compensation and benefits, third-party fees paid to consultants, occupancy costs, pre-production engineering mask costs, engineering samples and prototypes, packaging, test development and product qualification costs. In certain situations, the Company enters into engineering services agreements with certain customers to develop ICs. The costs incurred in satisfying these contracts are recorded as research and development expenses. Research and development expenses also include amortization of certain intangible assets acquired through business combinations. All research and development costs are expensed as incurred.
Selling, General and Administrative Expenses	Selling, General, and Administrative Expenses Selling, general, and administrative expenses include employee compensation and benefits for executive management, finance, sales, accounting, legal, human resources and other administrative personnel. In addition, it includes marketing and advertising, outside legal, tax and accounting services, insurance, and occupancy costs and related overhead costs allocated based on headcount. Selling, general, and administrative costs also include amortization of certain intangible assets acquired through business combinations. Selling, general, and administrative costs are expensed as incurred.
Restructuring Costs	Restructuring Costs In May 2025, the Company initiated a restructuring plan designed to improve operational efficiencies, reduce operating costs, better align the Company's workforce with top strategic priorities and key growth opportunities, and exit over time some of the Company's lower margin products outside of the ADAS application (the "2025 Restructuring Plan"). The 2025 Restructuring Plan includes, but is not limited to, consolidation of facilities, reduction of workforce in various geographic locations, impairment of certain intangible assets related to intellectual property licenses and early termination of certain contractual obligations. In August 2024, the Company initiated a plan intended to improve its operating performance (the “2024 Restructuring Plan”). The 2024 Restructuring Plan consisted of actions including, but not limited to, workforce and facilities reductions. Due to the size, nature and frequency of both the 2025 Restructuring Plan and the 2024 Restructuring Plan, they are fundamentally different from the Company’s ongoing productivity actions. As a result, all pre-tax charges related to aforementioned initiatives are separately reflected in Restructuring costs in the consolidated statement of operations.
Share-Based Compensation	Share-Based Compensation The Company recognizes compensation expense for all share-based payment awards made to employees and directors. The fair value of share-based payment awards is amortized over the requisite service period, which is defined as the period during which an employee is required to provide service in exchange for an award. The Company generally uses a straight-line attribution method for all grants that include only a service condition. Awards with both performance and service conditions are expensed over the service period for each separately vesting tranche. Share-based compensation expense recognized during the period includes actual expense on vested awards and expense associated with unvested awards. Forfeitures are recorded as incurred. The determination of fair value of restricted and certain market- or performance-based stock awards and units is based on the value of the Company’s stock on the date of grant with performance-based awards and units adjusted for the actual outcome of the underlying vesting conditions. The determination of fair value of shares issued through the Company’s Employee Equity Participation Plan and options granted are based on the Black-Scholes model. The fair value of market-based awards is based on Monte Carlo Simulations analysis.
Income Taxes	Income Taxes On June 10, 2021, we completed a series of transactions (the “Transaction”) with Thunder Bridge Acquisition II, Ltd (“TB2”) pursuant to the Master Transactions Agreement dated December 14, 2020, as amended on May 3, 2021 (the “MTA”). In connection with the Transaction, Thunder Bridge II Surviving Pubco, Inc, a Delaware corporation (“Surviving Pubco”), was formed to be the successor public company to TB2, TB2 was domesticated into a Delaware corporation and merged with and into a merger subsidiary of Surviving Pubco, and Surviving Pubco changed its name to indie Semiconductor, Inc. As a result of the Transaction, indie Semiconductor, Inc. became the holding company for ADK LLC. ADK LLC is treated as a partnership for U.S. federal and most applicable state and local income tax purposes. As a partnership, ADK LLC is not subject to U.S. federal and certain state and local income taxes. Any taxable income or loss generated by ADK LLC is passed through to and included in the taxable income or loss of its members, including indie, based on its economic interest held in the partnership. indie is taxed as a corporation and is subject to U.S. federal, state and local income taxes with respect to its allocable share of any taxable income or loss of ADK LLC, as well as any stand-alone income or loss generated by indie. Income taxes are recognized based upon our underlying annual blended federal, state and foreign income tax rates for the year. As the sole managing member of ADK LLC, indie Semiconductor, Inc. consolidates the financial results of ADK LLC and its subsidiaries. Further, indie Semiconductor Inc. is taxed as a corporation and is subject to U.S. federal, state and local income taxes with respect to its allocable share of any taxable income or loss of ADK LLC, as well as any stand-alone income or loss generated by indie. Income tax benefits for the year ended December 31, 2025 are primarily related to the Company’s foreign operations and U.S. subsidiaries that are nonconsolidated for tax purposes. Income tax benefits for the year ended December 31, 2024 are primarily related to our foreign operations. The Company accounts for income taxes under the asset and liability method pursuant to ASC 740 for its corporate subsidiaries. Under this method, the Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recorded for deferred tax assets if it is more likely than not that some portion or all of the deferred tax assets will not be realized based on all available positive and negative evidence. As of December 31, 2025, the Company continues to maintain a full valuation allowance against its deferred tax assets in the United States, but has released the valuation allowance for entities in China. The Company recognizes liabilities for uncertain tax positions based on a two-step process regarding recognition and measurement. The Company recognizes a tax benefit only if it is more likely than not the tax position will be sustained on examination by the local taxing authorities based on the technical merits of the position. The Company then measures the tax benefits recognized in the financial statements from such positions based on the largest benefit greater than 50% likelihood of being realized upon ultimate settlement with the related tax authority. The changes in recognition or measurement are reflected in the period in which the change in judgment occurs based on new information not previously available. As of December 31, 2025, the Company has not identified any uncertain tax positions. The Company records interest and penalties related to unrecognized tax benefits in its tax provision. As of December 31, 2025, no accrued interest or penalties are recorded on the consolidated balance sheet, and the Company has not recorded any related expenses.
Comprehensive Loss	Comprehensive Loss Other comprehensive loss consists of two components, net loss and other comprehensive income (loss) (“OCI”). OCI refers to revenue, expenses and gains and losses that under U.S. GAAP are recorded as an element of stockholders’ equity and excluded from net income (loss). indie’s OCI consists of foreign currency translation adjustments from its subsidiaries not using the U.S. dollar as their functional currency. Foreign currency translation gain (loss) adjustments of $23,828, ($18,814) and $5,781 represent the difference between net loss and comprehensive loss for the years ended December 31, 2025, 2024 and 2023, respectively.
Net Loss Per Share Attributable to Common Stockholders	Net Loss Per Share Attributable to Common Stockholders The Company’s basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period. The computation of net loss attributable to common stockholders is computed by deducting net earnings or loss attributable to non-controlling interests from the consolidated net earnings or loss. The diluted net loss per share attributable to common stockholders is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. The dilutive effect of these potential common shares is reflected in diluted earnings per share by application of (i) the treasury stock method for assumed exercise of stock options, vesting of outstanding equity awards; and (ii) if-converted method for assumed issuance of shares related to the convertible debt.
Stock Repurchase	Stock Repurchase The Company accounts for stock repurchases in the consolidated balance sheet by reducing common stock for the par value of the shares, reducing paid-in capital for the amount in excess of par to zero during the period in which the shares are repurchased, and recording the residual amount, if any, to retained earnings.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Issued Not Yet Adopted Accounting Pronouncements In December 2025, the FASB issued ASU 2025-12, Codification Improvements. The amendments in this update address changes to the Codification that clarify, correct errors and make minor improvements, making the Codification easier to understand and apply. The new guidance will be applied prospectively and is effective for fiscal years beginning after December 15, 2026, and interim periods within those annual reporting periods, with the option to apply retrospectively. Early adoption is permitted. The adoption of this guidance is not expected to have a significant impact on the Company's consolidated financial statements. In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements (ASU 2025-11), to amend the guidance in “Interim Reporting” (Topic 270). The update provides clarifications intended to improve the consistency and usability of interim disclosure requirements, including a comprehensive listing of required interim disclosures and a new disclosure principle for reporting material events occurring after the most recent annual period. The amendments do not change the underlying objectives of interim reporting but are designed to enhance clarity in application. The guidance is effective for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years. The Company is currently evaluating the impact that the new guidance will have on the presentation of our consolidated financial statements and accompanying notes. In July 2025, the FASB issued ASU No. 2025-05, Financial Instruments — Credit Losses (Topic 326): Measurements of Credit Losses for Accounts Receivable and Contract Assets (ASU 2025-05). The amendments in this update provide a practical expedient related to the estimation of expected credit losses for current accounts receivable and current contract assets that arise from transactions accounted for under FASB Accounting Standards Codification 606. Under ASU 2025-05, an entity is required to disclose whether it has elected to use the practical expedient. An entity that makes the accounting policy election is required to disclose the date through which subsequent cash collection are evaluated. ASU 2025-05 is effective for the Company beginning in the fiscal year ending February 28, 2027. The Company is currently evaluating the impacts of the adoption of ASU 2025-05 on the consolidated financial statements. In November 2024, the FASB issued ASU No. 2024-03, Income Statement — Reporting Comprehensive Income — Expenses Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which provides guidance to enhance disclosures related to the disaggregation of income statement expenses. The standard requires, in the notes to the financial statements, disclosure of specified information about certain costs and expenses which includes purchases of inventory, employee compensation, depreciation, and intangible asset amortization included in each relevant expense caption. The standard also requires amounts that are already required to be disclosed under U.S. GAAP in the same disclosure as the other disaggregation requirements, disclosure of a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively, and disclosure of the total amount of selling expenses and, in annual reporting periods, an entity's definition of selling expenses. The amendments in this standard are effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Companies have the option to apply the guidance either on a retrospective or prospective basis, and early adoption is permitted. The standard will become effective for indie for its fiscal year 2027 annual financial statements and interim financial statements thereafter and may be applied prospectively to periods after the adoption date or retrospectively for all prior periods presented in the financial statements, with early adoption permitted. The Company plans to adopt the standard when it becomes effective beginning in its fiscal year 2027 annual financial statements and is currently evaluating the impact this guidance will have on its consolidated financial statements. Recently Adopted Accounting Pronouncements In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740) — Improvements to Income Tax Disclosures, to require enhanced income tax disclosures to provide information to assess how an entity’s operations and related tax risks, tax planning, and operational opportunities affect its tax rate and prospects for future cash flows. The amendments in this update provide that a business entity disclose (1) a tabular income tax rate reconciliation, using both percentages and amounts, (2) separate disclosure of any individual reconciling items that are equal to or greater than 5% of the amount computed by multiplying the income (loss) from continuing operations before income taxes by the applicable statutory income tax rate, and disaggregation of certain items that are significant and (3) amount of income taxes paid (net of refunds received) disaggregated by federal, state and foreign jurisdictions, including separate disclosure of any individual jurisdictions greater than 5% of total income taxes paid. These amendments are effective for the Company for annual periods in 2025, applied prospectively, with early adoption and retrospective application permitted. The Company adopted the guidance as of December 31, 2025 on a prospective basis. The adoption of ASU 2023-09 did not have a material impact on the Company's consolidated financial statements (see Note 18 - Income Taxes for further information).

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2025

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the consolidated financial statements and the reported amounts of expenses during the reporting period. Actual results could differ materially from those estimates and assumptions.

On an ongoing basis, management evaluates its estimates assumptions, including those related to (i) the collectability of accounts receivable; (ii) write-down for excess and obsolete inventories; (iii) valuation of acquired intangibles and goodwill; (iv) warranty obligations; (v) the value assigned to and estimated useful lives of long-lived assets; (vi) the realization of tax assets and estimates of tax liabilities and tax reserves; (vii) amounts recorded in connection with acquisitions; (viii) recoverability of intangible assets and goodwill; (ix) the recognition and disclosure of fair value of debt instruments and contingent liabilities; (x) the computation of share-based compensation; (xi) accrued expenses; and (xii) the recognition of revenue based on a cost-to-cost measure of progress for certain engineering services contracts. These estimates are based on historical data and experience, as well as various other factors that management believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. The Company engages third-party valuation specialists to assist with estimates related to the valuation of certain financial instruments and assets acquired in connection with acquisitions as well as the valuation of reporting units and certain intangible assets in connection with quantitative impairment analyses

over goodwill and intangible assets. Such estimates often require the selection of appropriate valuation methodologies and models, and significant judgment in evaluating ranges of assumptions and financial inputs. Actual results may differ from those estimates under different assumptions or circumstances.

Foreign Currency

Certain of the Company’s self-sustaining foreign subsidiaries use their respective local currency as their functional currency. Assets and liabilities for these subsidiaries have been translated into U.S. dollars at the exchange rates prevailing at the end of the period and results of operations at the average exchange rates for the period. Unrealized exchange gains and losses arising from the translation of the financial statements of our non-U.S. functional currency operations are accumulated in the cumulative translation adjustments account in accumulated other comprehensive loss.

For those foreign subsidiaries where the U.S. dollar is the functional currency, all foreign currency-denominated accounts are remeasured into U.S. dollars. Unrealized exchange gains and losses arising from remeasurements of foreign currency-denominated assets and liabilities are included within Other income (expense), net in the consolidated statements of operations and comprehensive loss. Gains and losses arising from international intercompany transactions that are of a long-term investment nature are reported in the same manner as translation gains and losses. Realized exchange gains and losses are included in net income for the periods presented.

Forward Exchange Contracts

The Company’s forward exchange contracts, which are used to hedge anticipated U.S. dollar denominated sales and purchases as well as other foreign currency denominated sales and purchases such as Canadian Dollar, Euro and Great British Pound do not qualify for hedge accounting and are recognized at fair value. Any change in the fair value of these contracts is reflected as part of Other income (expense), net in the consolidated statement of operations.

Consolidation

The consolidated financial statements comprise the financial statements of the Company, its wholly owned subsidiaries, and subsidiaries that it controls due to ownership of a majority voting interest. Subsidiaries are fully consolidated from the date of acquisition, being the date on which the Company obtains control, and continue to be consolidated until the date when such control ceases. All significant intercompany accounts and transactions are eliminated in consolidation. The Company recognizes noncontrolling interest related to its less-than-wholly-owned subsidiary as equity in the consolidated financial statements separate from the parent entity’s equity. The net loss attributable to noncontrolling interest is included in net loss in the consolidated statements of operations and comprehensive loss.

Cash and Cash Equivalents

Cash and cash equivalents are defined as short-term, highly liquid investments with original maturities of 90 days or less at the date of purchase. As of December 31, 2025 and 2024, cash and cash equivalents consisted of money market funds and cash deposits that were held by reputable financial institutions in local jurisdictions of the Company’s subsidiaries including primarily the United States, Austria, Canada, China, Germany, Great Britain and Switzerland denominated in U.S. dollars and local currency.

Restricted Cash

The Company’s restricted cash consists of cash that the Company is contractually obligated to maintain in accordance with the terms of its Wells Fargo Bank revolving line of credit agreement.

Accounts Receivable

Accounts receivable consist of amounts due primarily from customers for product sales and engineering services agreements. Accounts receivable are recorded at the invoiced amount and do not bear interest. The Company accounts for potential losses in accounts receivable utilizing the allowance method. The Company closely monitors outstanding accounts receivable and considers its knowledge of customers, historical losses, and current and expected economic conditions in establishing the allowance for doubtful accounts. The

Company wrote off $1,831 of accounts receivable, which was fully reserved under the allowance for doubtful accounts in the prior years, for the year ended December 31, 2025. The Company did not have any write-offs in any other periods presented.

Concentration of Credit Risk

The Company deposits its cash with large financial institutions. At times, the Company’s cash balances with individual banking institutions will exceed the limits insured by the FDIC, however, the Company has not experienced any losses on such deposits.

The Company extends credit to its customers based upon an evaluation of the customers’ financial condition and credit history and generally does not require collateral. Credit losses, if any estimated, are provided for in the consolidated financial statements and consistently have been within management’s expectations. See Note 15 — Revenue — Concentrations.

Inventory

The Company values inventories at the lower of cost or net realizable value on a first-in, first-out basis. Cost is computed using standard cost, which approximates actual cost, on a first-in, first-out basis. Inventories are reduced for write-downs based on periodic reviews for evidence of slow-moving or obsolete parts. The write-down is based on the comparison between inventory on hand and forecasted customer demand for each specific product. Once written down, inventory write-downs are not reversed until the inventory is sold or scrapped. Inventory write-downs are also established when conditions indicate the net realizable value is less than cost due to physical deterioration, technological obsolescence, changes in price level or other causes. All inventory provisions are recorded to cost of goods sold in the consolidated statement of operations.

Property and Equipment, net

The Company’s property and equipment primarily consist of lab equipment, production tooling and masks, equipment, furniture and fixtures, leasehold improvements, and computer hardware and software. Property and equipment are recorded at cost less accumulated depreciation. Depreciation is calculated using the straight-line method based on the estimated useful lives of between three and seven years and for leasehold improvements the lesser of the remaining lease term or useful life. Major improvements are capitalized while routine repairs and maintenance are charged to expense when incurred.

Production masks with discernible future benefits, namely that they will be used to manufacture products to service customer demand, are capitalized and amortized over the estimated useful life of four years. Production masks being used for research and development or testing do not meet the criteria for capitalization and are expensed as research and development costs.

The Company recorded $376 of impairment charges related to certain software licenses as part of its 2025 Restructuring Plan.

Business Combinations

The Company accounts for its business acquisitions under the ASC Topic 805, Business Combinations guidance for business combinations. The total cost of acquisitions is allocated to the underlying identifiable net assets based on their respective estimated fair values. Determining the fair value of assets acquired and liabilities assumed requires management’s judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash inflows and outflows, discount rates, asset lives and market multiples, among other items.

Intangible Assets, net

The Company’s intangible assets include intangible assets acquired from business combinations, intellectual property (“IP”) and software licensed from third parties. The majority of the intangible assets have finite lives, except for those related to in-progress research and development (“IPR&D”), and are amortized over a period of two to twelve years, on a straight-line basis, which approximates the pattern in which economic benefits of these assets are expected to be utilized. IPR&D is considered to have indefinite life until the abandonment or completion of the associated research and development efforts. If the development is abandoned in the future, these assets will be expensed in the period of abandonment. If and when the development activities are completed, IPR&D assets will be

reclassified to developed technology, management will make a determination of the useful lives and methods of amortization of these assets.

Goodwill

Goodwill represents the excess of the fair value of purchase consideration of an acquired business over the fair value of the identifiable net assets acquired. Goodwill is not amortized but is tested for impairment at a reporting unit level on an annual basis on October 1, or more frequently if circumstances change or an event occurs that would more likely than not reduce the fair value of a reporting unit below its carrying amount.

Significant judgment may be required when goodwill is assessed for impairment. Qualitative factors may be assessed to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount. If the assessment of all relevant qualitative factors indicates that it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, a quantitative goodwill impairment test is not necessary. These qualitative factors may include, but are not limited to, a significant change in the macroeconomic and business climate, medium to long-term revenue forecasts per industry trend and/or product launch timeline, operating performance indicators, adequacy of capital level to support ongoing business needs, and other factors. If the assessment of all relevant qualitative factors indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company will perform a quantitative goodwill impairment test. The quantitative impairment test for goodwill consists of a comparison of the fair value of a reporting unit with its carrying value, including the goodwill allocated to that reporting unit. If the carrying value of a reporting unit exceeds its fair value, the Company will recognize an impairment loss equal to the amount of the excess, limited to the amount of goodwill allocated to that reporting unit. Application of the impairment test requires judgment, including the identification of reporting units, assignment of assets and liabilities to reporting units and the determination of fair value of each reporting unit. For the year ended December 31, 2025, the Company performed a quantitative analysis over its two reporting units on October 1 using a combination of the income and market valuation approaches. The fair value of both reporting units exceeded their carrying values. For the years ended December 31, 2024 and 2023, the Company performed a qualitative analysis over its two reporting units on October 1 and concluded that it was not more likely than not that the fair value of the reporting units were less than their carrying amount. As a result, the Company did not record any impairment to goodwill for the years ended December 31, 2025, 2024 and 2023.

Impairment of Long-Lived Assets

The Company reviews its long-lived assets, consisting of property and equipment, right-of-use assets and intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company regularly reviews its operating performance for indicators of impairment. Factors considered important that could trigger an impairment review include a significant underperformance relative to expected historical or projected future operating results, or a significant change in the manner of the use of the assets. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset (or asset group) to estimated undiscounted future cash flows expected to be generated by the asset (or asset group). If the carrying amount of an asset (or asset group) exceeds its estimated undiscounted future cash flows, an impairment charge is recognized to the extent the fair value is less than the carrying value. The Company recorded $3,260 of impairment charges related to certain software licenses as part of its 2025 Restructuring Plan. The Company recorded $998 of impairment charges related to certain property and equipment and right-of-use assets for the year ended December 31, 2024 as part of its 2024 Restructuring Plan initiative that commenced in August 2024 (see Note 4 — Restructuring Costs). As a result, all pre-tax charges related to such initiatives are separately reflected in Restructuring costs in the consolidated statement of operations. The Company did not record any impairment to long-lived assets for the years ended December 31, 2023.

Fair Value Measurements

Fair value is defined as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between willing, able and knowledgeable market participants at the measurement date. Fair value measurements are not adjusted for transaction costs. In addition, a three-tiered hierarchy for inputs is used in management’s determination of fair value of financial instruments that emphasizes the use of observable inputs over the use of unobservable inputs by requiring that the observable inputs be used when available. Observable inputs are market participant assumptions based on market data obtained from sources independent of

the Company. Unobservable inputs are the reporting entity’s own assumptions about market participants based on the best information available under the circumstances. In assessing the appropriateness of using observable inputs in making its fair value determinations, the Company considers whether the market for a particular security is “active” or not based on all the relevant facts and circumstances.

Valuation service providers typically obtain data about market transactions and other key valuation model inputs from multiple sources and, through the use of widely accepted valuation models, provide a single fair value measurement for individual securities for which a fair value has been requested under the terms of service agreements. The inputs used by the valuation service providers include, but are not limited to, market prices from recently completed transactions and transactions of comparable securities, interest rate yield curves, credit spreads, currency rates and other market observable information, as applicable. The valuation models consider, among other things, market observable information as of the measurement date as well as the specific attributes of the security being valued including its term, interest rate, credit rating, industry sector and, when applicable, collateral quality and other issue or issuer specific information. When market transactions or other market observable data is limited, the extent to which judgment is applied in determining fair value is greatly increased.

As a basis for considering such assumptions, a three-tier value hierarchy is used in management’s determination of fair value based on the reliability and observability of inputs as follows:

Level 1 — Valuations are based on unadjusted quoted prices in active markets that the Company has the ability to access for identical, unrestricted assets and do not involve any meaningful degree of judgment. An active market is defined as a market where transactions for the financial instrument occur with sufficient frequency and volume to provide pricing information on an ongoing basis;

Level 2 — Valuations are based on direct and indirect observable inputs other than quoted market prices included in Level 1. Level 2 inputs include quoted prices for similar assets in active markets and inputs other than quoted prices that are observable for the asset, such as the terms of the security and market-based inputs; and

Level 3 — Valuations are based on techniques that use significant inputs that are unobservable. The valuation of Level 3 assets and liabilities requires the greatest degree of judgment. These measurements may be made under circumstances in which there is little, if any, market activity for the asset or liability. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment. In making the assessment, the Company considers factors specific to the asset. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement is classified is determined based on the lowest level input that is significant to the fair value measurement in its entirety.

See Note 11 — Contingent and Earn-Out Liabilities and Note 12 — Fair Value Measurements for additional information.

The Company’s fair value measurements in each reporting period include cash equivalents, debt instruments, share-based awards, contingent considerations and earn-out liabilities. The Company’s financial instruments of accounts receivable, accounts payable and accrued expenses are stated at their carrying value, which approximates fair value due to the short time to the expected receipt or payment date. The Company continues to remeasure its contingent considerations and earn-out liabilities associated with business combinations using Level 3 fair value measurements.

Warrant Liability

The Company accounted for the Public Warrants and the Private Warrants, which were issued on June 10, 2021 in connection with the Transaction (as defined below), in accordance with ASC 815-40, Derivatives and Hedging—Contracts in Entity’s Own Equity (“ASC 815”), under which the Warrants do not meet the criteria for equity classification and must be recorded as liabilities. As the Warrants did not meet the definition of a derivative as contemplated in ASC 815, the warrants were measured at fair value at inception and at each reporting date in accordance with ASC 820, Fair Value Measurement, with changes in fair value recognized as a component of Other income (expense), net on the consolidated statement of operations. During the year ended December 31, 2023, indie completed

the exchange of the Warrants, which eliminated the need for future remeasurement of the warrant liabilities. See Note 1 - Nature of the Business and Basis of Presentation - Warrant Exchange for further information.

Segment Information

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The chief operating decision maker (“CODM”) is the Chief Executive Officer. The Company has multiple business activities and are managed and held accountable for operations, operating results and plans for levels or components below the consolidated unit level by individual segment managers. However, discrete financial information is not reviewed by the CODM as the operating results of the Company are reviewed by the CODM only on a consolidated basis. Accordingly, the Company has one operating segment, and therefore, one reportable segment.

Revenue

Revenue is primarily derived from the design and sale of semiconductor solutions. Revenue is recognized within the scope of ASC 606, Revenue from Contracts with Customers. The Company recognizes product revenue in the consolidated statement of operations when it satisfies performance obligations under the terms of its contracts and upon transfer of control at a point in time when title transfers either upon shipment to or receipt by the customer as determined by the contractual shipping terms of the contract, net of accruals for estimated sales returns and allowances. To date, total returns and allowances issued by the Company has been de minimis. Sales and other taxes the Company collects, if any, are excluded from revenue. Product revenue arrangements do not contain significant financing components.

The Company generally offers a limited warranty to customers covering a period of twelve months which obligates the Company to repair or replace manufacturing defective products. The warranty is not sold separately and does not represent a separate performance obligation. Therefore, such warranties are accounted for under ASC 460, Guarantees, and the estimated costs of warranty claims are accrued as cost of goods sold in the period the related revenue is recorded. Infrequently, the Company offers an extended limited warranty to customers for certain products. The Company accrues for known warranty and indemnification issues if a loss is probable and can be reasonably estimated. As of December 31, 2025, total warranty liability is not material.

Engineering services contracts with customers typically contain only one distinct performance obligation, which is primarily design services for integrated circuits (“ICs”) based on agreed upon specifications. Engineering services contracts typically also include the purchase, at the customer’s option, of the designed products at agreed upon prices subsequent to completion of the design services. The Company has determined that the option to purchase these products is not a material right and has not allocated transaction price to this provision.

For these engineering services arrangements, revenue is recognized over time as services are provided based on the terms of the contract on an input basis, using costs incurred as the measure of progress and is recorded as contract revenue in the consolidated statement of operations. The costs incurred represent the most reliable measure of transfer of control to the customer. Revenue is deferred for amounts billed or received prior to delivery of the services.

Practical Expedients and Elections

ASC 606 requires disclosure of the aggregate amount of transaction price that is allocated to performance obligations that have not yet been satisfied as of the reporting periods presented. The guidance provides certain practical expedients that limit this requirement and, therefore, disclosure of the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which revenue is recognized at the amount to which the Company has the right to invoice for services performed

is not provided. The Company has elected not to disclose the aggregate amount of transaction prices associated with unsatisfied or partially unsatisfied performance obligations for contracts where these criteria are met.

The Company’s policy is to capitalize any incremental costs incurred to obtain a customer contract, only to the extent that the benefit associated with the costs is expected to be longer than one year. Capitalizable contract costs were not significant as of both December 31, 2025 and 2024 and accordingly, no costs have been capitalized.

The Company accounts for shipping and handling activities related to contracts with customers as costs to fulfill the promise to transfer the associated products. When shipping and handling costs are incurred after a customer obtains control of the products, the Company has elected to account for these as costs to fulfill the promise and not as a separate performance obligation. Shipping and handling costs associated with the distribution of products to customers are insignificant, but if incurred, are recorded in cost of goods sold generally when the related product is shipped to the customer.

Upon adoption of ASC 842, Leases, the Company elected the package of practical expedients permitted under the transition guidance, which does not require reassessment of prior conclusions related to contracts containing a lease, lease classification and initial direct lease costs. Further, the Company elected to exclude short-term leases (term of 12 months or less) from the balance sheet presentation and accounted for non-lease and lease components in a contract as a single lease for certain asset classes.

Cost of Goods Sold

Cost of goods sold includes cost of materials and contract manufacturing services, including semiconductor wafers processed by third-party foundries, costs associated with packaging, assembly, testing and shipping products. In addition, cost of goods sold includes the costs of personnel, certain royalties for embedded intellectual property, production tooling used in the manufacturing process, logistics, warranty, and amortization of production mask costs. Cost of goods sold also include amortization of certain intangible assets acquired through business combinations.

In addition to generating revenues from product shipments, the Company recognizes revenues related to certain engineering services contracts which help offset the costs of developing ICs for customers. The costs associated with fulfilling these contracts are expensed as incurred as research and development in the period incurred.

Research and Development Expense

Research and Development Expenses

Research and development expenses consist of costs incurred in performing product design and development activities including employee compensation and benefits, third-party fees paid to consultants, occupancy costs, pre-production engineering mask costs, engineering samples and prototypes, packaging, test development and product qualification costs. In certain situations, the Company enters into engineering services agreements with certain customers to develop ICs. The costs incurred in satisfying these contracts are recorded as research and development expenses. Research and development expenses also include amortization of certain intangible assets acquired through business combinations. All research and development costs are expensed as incurred.

Selling, General and Administrative Expenses

Selling, General, and Administrative Expenses

Selling, general, and administrative expenses include employee compensation and benefits for executive management, finance, sales, accounting, legal, human resources and other administrative personnel. In addition, it includes marketing and advertising, outside legal, tax and accounting services, insurance, and occupancy costs and related overhead costs allocated based on headcount. Selling, general, and administrative costs also include amortization of certain intangible assets acquired through business combinations. Selling, general, and administrative costs are expensed as incurred.

Restructuring Costs

In May 2025, the Company initiated a restructuring plan designed to improve operational efficiencies, reduce operating costs, better align the Company's workforce with top strategic priorities and key growth opportunities, and exit over time some of the Company's lower margin products outside of the ADAS application (the "2025 Restructuring Plan"). The 2025 Restructuring Plan includes, but is

not limited to, consolidation of facilities, reduction of workforce in various geographic locations, impairment of certain intangible assets related to intellectual property licenses and early termination of certain contractual obligations.

In August 2024, the Company initiated a plan intended to improve its operating performance (the “2024 Restructuring Plan”). The 2024 Restructuring Plan consisted of actions including, but not limited to, workforce and facilities reductions.

Due to the size, nature and frequency of both the 2025 Restructuring Plan and the 2024 Restructuring Plan, they are fundamentally different from the Company’s ongoing productivity actions. As a result, all pre-tax charges related to aforementioned initiatives are separately reflected in Restructuring costs in the consolidated statement of operations.

Share-Based Compensation

The Company recognizes compensation expense for all share-based payment awards made to employees and directors. The fair value of share-based payment awards is amortized over the requisite service period, which is defined as the period during which an employee is required to provide service in exchange for an award. The Company generally uses a straight-line attribution method for all grants that include only a service condition. Awards with both performance and service conditions are expensed over the service period for each separately vesting tranche.

Share-based compensation expense recognized during the period includes actual expense on vested awards and expense associated with unvested awards. Forfeitures are recorded as incurred.

The determination of fair value of restricted and certain market- or performance-based stock awards and units is based on the value of the Company’s stock on the date of grant with performance-based awards and units adjusted for the actual outcome of the underlying vesting conditions. The determination of fair value of shares issued through the Company’s Employee Equity Participation Plan and options granted are based on the Black-Scholes model. The fair value of market-based awards is based on Monte Carlo Simulations analysis.

Income Taxes

On June 10, 2021, we completed a series of transactions (the “Transaction”) with Thunder Bridge Acquisition II, Ltd (“TB2”) pursuant to the Master Transactions Agreement dated December 14, 2020, as amended on May 3, 2021 (the “MTA”). In connection with the Transaction, Thunder Bridge II Surviving Pubco, Inc, a Delaware corporation (“Surviving Pubco”), was formed to be the successor public company to TB2, TB2 was domesticated into a Delaware corporation and merged with and into a merger subsidiary of Surviving Pubco, and Surviving Pubco changed its name to indie Semiconductor, Inc. As a result of the Transaction, indie Semiconductor, Inc. became the holding company for ADK LLC. ADK LLC is treated as a partnership for U.S. federal and most applicable state and local income tax purposes. As a partnership, ADK LLC is not subject to U.S. federal and certain state and local income taxes. Any taxable income or loss generated by ADK LLC is passed through to and included in the taxable income or loss of its members, including indie, based on its economic interest held in the partnership. indie is taxed as a corporation and is subject to U.S. federal, state and local income taxes with respect to its allocable share of any taxable income or loss of ADK LLC, as well as any stand-alone income or loss generated by indie.

Income taxes are recognized based upon our underlying annual blended federal, state and foreign income tax rates for the year. As the sole managing member of ADK LLC, indie Semiconductor, Inc. consolidates the financial results of ADK LLC and its subsidiaries. Further, indie Semiconductor Inc. is taxed as a corporation and is subject to U.S. federal, state and local income taxes with respect to its allocable share of any taxable income or loss of ADK LLC, as well as any stand-alone income or loss generated by indie. Income tax benefits for the year ended December 31, 2025 are primarily related to the Company’s foreign operations and U.S. subsidiaries that are nonconsolidated for tax purposes. Income tax benefits for the year ended December 31, 2024 are primarily related to our foreign operations.

The Company accounts for income taxes under the asset and liability method pursuant to ASC 740 for its corporate subsidiaries. Under this method, the Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences

between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recorded for deferred tax assets if it is more likely than not that some portion or all of the deferred tax assets will not be realized based on all available positive and negative evidence. As of December 31, 2025, the Company continues to maintain a full valuation allowance against its deferred tax assets in the United States, but has released the valuation allowance for entities in China.

The Company recognizes liabilities for uncertain tax positions based on a two-step process regarding recognition and measurement. The Company recognizes a tax benefit only if it is more likely than not the tax position will be sustained on examination by the local taxing authorities based on the technical merits of the position. The Company then measures the tax benefits recognized in the financial statements from such positions based on the largest benefit greater than 50% likelihood of being realized upon ultimate settlement with the related tax authority. The changes in recognition or measurement are reflected in the period in which the change in judgment occurs based on new information not previously available. As of December 31, 2025, the Company has not identified any uncertain tax positions.

The Company records interest and penalties related to unrecognized tax benefits in its tax provision. As of December 31, 2025, no accrued interest or penalties are recorded on the consolidated balance sheet, and the Company has not recorded any related expenses.

Comprehensive Loss

Other comprehensive loss consists of two components, net loss and other comprehensive income (loss) (“OCI”). OCI refers to revenue, expenses and gains and losses that under U.S. GAAP are recorded as an element of stockholders’ equity and excluded from net income (loss). indie’s OCI consists of foreign currency translation adjustments from its subsidiaries not using the U.S. dollar as their functional currency. Foreign currency translation gain (loss) adjustments of $23,828, ($18,814) and $5,781 represent the difference between net loss and comprehensive loss for the years ended December 31, 2025, 2024 and 2023, respectively.

Net Loss Per Share Attributable to Common Stockholders

The Company’s basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period. The computation of net loss attributable to common stockholders is computed by deducting net earnings or loss attributable to non-controlling interests from the consolidated net earnings or loss. The diluted net loss per share attributable to common stockholders is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. The dilutive effect of these potential common shares is reflected in diluted earnings per share by application of (i) the treasury stock method for assumed exercise of stock options, vesting of outstanding equity awards; and (ii) if-converted method for assumed issuance of shares related to the convertible debt.

Stock Repurchase

The Company accounts for stock repurchases in the consolidated balance sheet by reducing common stock for the par value of the shares, reducing paid-in capital for the amount in excess of par to zero during the period in which the shares are repurchased, and recording the residual amount, if any, to retained earnings.

Recent Accounting Pronouncements

Recently Issued Not Yet Adopted Accounting Pronouncements

In December 2025, the FASB issued ASU 2025-12, Codification Improvements. The amendments in this update address changes to the Codification that clarify, correct errors and make minor improvements, making the Codification easier to understand and apply. The new guidance will be applied prospectively and is effective for fiscal years beginning after December 15, 2026, and interim periods within those annual reporting periods, with the option to apply retrospectively. Early adoption is permitted. The adoption of this guidance is not expected to have a significant impact on the Company's consolidated financial statements.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements (ASU 2025-11), to amend the guidance in “Interim Reporting” (Topic 270). The update provides clarifications intended to improve the consistency and usability of interim disclosure requirements, including a comprehensive listing of required interim disclosures and a new disclosure principle for reporting material events occurring after the most recent annual period. The amendments do not change the underlying objectives of interim reporting but are designed to enhance clarity in application. The guidance is effective for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years. The Company is currently evaluating the impact that the new guidance will have on the presentation of our consolidated financial statements and accompanying notes.

In July 2025, the FASB issued ASU No. 2025-05, Financial Instruments — Credit Losses (Topic 326): Measurements of Credit Losses for Accounts Receivable and Contract Assets (ASU 2025-05). The amendments in this update provide a practical expedient related to the estimation of expected credit losses for current accounts receivable and current contract assets that arise from transactions accounted for under FASB Accounting Standards Codification 606. Under ASU 2025-05, an entity is required to disclose whether it has elected to use the practical expedient. An entity that makes the accounting policy election is required to disclose the date through which subsequent cash collection are evaluated. ASU 2025-05 is effective for the Company beginning in the fiscal year ending February 28, 2027. The Company is currently evaluating the impacts of the adoption of ASU 2025-05 on the consolidated financial statements.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement — Reporting Comprehensive Income — Expenses Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which provides guidance to enhance disclosures related to the disaggregation of income statement expenses. The standard requires, in the notes to the financial statements, disclosure of specified information about certain costs and expenses which includes purchases of inventory, employee compensation, depreciation, and intangible asset amortization included in each relevant expense caption. The standard also requires amounts that are already required to be disclosed under U.S. GAAP in the same disclosure as the other disaggregation requirements, disclosure of a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively, and disclosure of the total amount of selling expenses and, in annual reporting periods, an entity's definition of selling expenses. The amendments in this standard are effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Companies have the option to apply the guidance either on a retrospective or prospective basis, and early adoption is permitted. The standard will become effective for indie for its fiscal year 2027 annual financial statements and interim financial statements thereafter and may be applied prospectively to periods after the adoption date or retrospectively for all prior periods presented in the financial statements, with early adoption permitted. The Company plans to adopt the standard when it becomes effective beginning in its fiscal year 2027 annual financial statements and is currently evaluating the impact this guidance will have on its consolidated financial statements.

Recently Adopted Accounting Pronouncements

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740) — Improvements to Income Tax Disclosures, to require enhanced income tax disclosures to provide information to assess how an entity’s operations and related tax risks, tax planning, and operational opportunities affect its tax rate and prospects for future cash flows. The amendments in this update provide that a business entity disclose (1) a tabular income tax rate reconciliation, using both percentages and amounts, (2) separate disclosure of any individual reconciling items that are equal to or greater than 5% of the amount computed by multiplying the income (loss) from continuing operations before income taxes by the applicable statutory income tax rate, and disaggregation of certain items that are significant and (3) amount of income taxes paid (net of refunds received) disaggregated by federal, state and foreign jurisdictions, including separate disclosure of any individual jurisdictions greater than 5% of total income taxes paid. These amendments are effective for the Company for annual periods in 2025, applied prospectively, with early adoption and retrospective application permitted. The Company adopted the guidance as of December 31, 2025 on a prospective basis. The adoption of ASU 2023-09 did not have a material impact on the Company's consolidated financial statements (see Note 18 - Income Taxes for further information).
