Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of the Business and Basis of Presentation	Nature of the Business and Basis of Presentation indie Semiconductor, Inc. (“indie”) and its predecessor for accounting purposes, Ay Dee Kay, LLC, a California limited liability company (“ADK LLC”) and its subsidiaries are collectively referred to herein as the “Company.” The Company offers highly innovative automotive semiconductors and software solutions for Advanced Driver Assistance Systems (“ADAS”), autonomous vehicle, connected car, user experience and electrification applications. The Company focuses on edge sensors across multiple modalities spanning LiDAR, radar, ultrasound and computer vision. These functions represent the core underpinnings of both electric and autonomous vehicles, while the advanced user interfaces are transforming the in-cabin experience to mirror and seamlessly connect to the mobile platforms people rely on every day. indie is an approved vendor to Tier 1 automotive suppliers and its platforms can be found in marquee automotive manufacturers around the world. Headquartered in Aliso Viejo, California, indie has design centers and sales offices in Austin, Texas; Detroit, Michigan; San Jose, California; Cordoba, Argentina; Budapest, Hungary; Dresden, Frankfurt an der Oder, Munich and Nuremberg, Germany; Edinburgh, Scotland; Schlieren, Switzerland; Rabat, Morocco; Haifa, Israel; Quebec City and Toronto, Canada; Seoul, South Korea; Tokyo, Japan and several locations throughout China. The Company engages subcontractors to manufacture its products. The majority of these subcontractors are located in Asia. Execution of At-The-Market Agreement On August 26, 2022, the Company entered into an At Market Issuance Agreement (“ATM Agreement”) with B. Riley Securities, Inc., Craig-Hallum Capital Group LLC and Roth Capital Partners, LLC (collectively as “Sales Agents”) relating to shares of its Class A common stock, par value $0.0001 per share (the “Class A common stock”). In accordance with the terms of the ATM Agreement, the Company may offer and sell shares of its Class A common stock having an aggregate offering price of up to $150,000 from time to time through the Sales Agents, acting as the Company’s agent or principal. The Company implemented this program for the flexible access that it provides to the capital markets. As of March 31, 2025, and since the inception of the program indie has raised gross proceeds of $90,187 and issued 11,138,984 shares of Class A common stock at an average per-share sales price of $8.10 and had approximately $59,813 available for future issuances under the ATM Agreement. During both the three months ended March 31, 2025 and March 31, 2024, there was no ATM related activity. Risks and Uncertainties The Company is impacted by macroeconomic conditions including continued inflation, rising prices or rising interest rates, geopolitical tensions, the risk of recession, and the effect of trade policies, which have a combined effect on overall economic activity and consumer demand for automotive products that has resulted in lower production levels for the Company’s products. Tariffs against semiconductor producing countries such as Taiwan, and retaliatory tariffs by countries such as China, could cause a decrease in the sales of the Company’s products to customers, other customers selling to end users, or other global customers, which could materially and adversely affect the Company’s business, financial condition and results of operation. The ultimate impact of any tariffs will depend on various factors, including the outcome of ongoing negotiations, the timing of implementation, and the amount, scope and nature of the tariffs. Additionally, the conflict in the Middle East and the implication of this event has created global political and economic uncertainty. The Company is closely monitoring developments, including potential impact to the Company’s business, customers, suppliers, its employees and operations in Israel, the Middle East and elsewhere. At this time, the impact to indie is subject to change given the volatile nature of the situation. Refer to Part I, Item 1A of our 2024 Annual Report on Form 10-K for the fiscal year ended December 31, 2024 under the heading “Risk Factors” for more information on our risks and uncertainties. Basis of Presentation The condensed consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”). Any reference in these notes to applicable guidance is meant to refer to the authoritative U.S. GAAP as found in the Accounting Standards Codification (“ASC”) and the Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). The condensed consolidated financial statements include the condensed consolidated accounts of the Company’s majority-owned subsidiary, ADK LLC, of which approximately 92% was owned by indie as of March 31, 2025. ADK LLC’s condensed consolidated financial statements include its wholly-owned subsidiaries indie Services Corporation, indie LLC and indie City LLC, all California entities, Ay Dee Kay Limited (“Ay Dee Kay Ltd”), a private limited company incorporated under the laws of Scotland, indie GmbH, Symeo GmbH (“Symeo”) and Silicon Radar GmbH (“Silicon Radar”), all of which are private limited liability companies incorporated under the laws of Germany, Exalos AG (“Exalos”), a company limited by shares organized under the laws of Switzerland, indie Kft, a limited liability company incorporated under the laws of Hungary, TeraXion Inc. (“TeraXion”) and Geo Semiconductor Canada Inc., both incorporated under the laws of Canada, indie Semiconductor Israel Ltd., a private limited company incorporated under the laws of Israel, Ay Dee Kay S.A., a limited liability company incorporated under the laws of Argentina, indie Semiconductor Morocco, a limited liability company under the laws of Morocco, indie Semiconductor Japan KK, a limited liability company under the laws of Japan, Wuxi indie Microelectronics (“Wuxi”), a Chinese entity with approximately 59% voting controlled and approximately 34% owned by the Company as of March 31, 2025 and Wuxi’s wholly-owned subsidiaries, indie Semiconductor Suzhou, indie Semiconductor HK, Ltd and Shanghai Ziying Microelectronics Co., Ltd. All significant intercompany accounts and transactions of the subsidiaries have been eliminated in consolidation. The noncontrolling interest attributable to the Company’s less-than-wholly-owned subsidiary is presented as a separate component from stockholders’ equity (deficit) in the condensed consolidated balance sheets, and a noncontrolling interest in the condensed consolidated statements of operations and condensed consolidated statements of stockholders’ equity (deficit) and noncontrolling interest. Unaudited Interim Financial Information The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC for interim financial reporting. Certain information and footnote disclosures, normally included in annual consolidated financial statements prepared in accordance with U.S. GAAP, have been condensed or omitted pursuant to those rules and regulations. However, in management’s opinion, the financial information reflects all adjustments, including those of a normal recurring nature, necessary to present fairly the results of operations, financial position, and cash flows of the Company for the periods presented. The results of operations, financial position, and cash flows for the Company during the interim periods are not necessarily indicative of those expected for the full year. This information should be read in conjunction with the Company’s consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024, filed with the SEC on March 3, 2025. Significant Accounting Policies The Company’s significant accounting policies are disclosed in its Annual Report on Form 10-K for the year ended December 31, 2024. There has been no material change to the Company’s significant accounting policies during the three months ended March 31, 2025. Recent Accounting Pronouncements Recently Issued Not Yet Adopted Accounting Pronouncements 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 condensed consolidated financial statements. 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 intends to adopt the amendments in this update prospectively in 2025. The impact of the adoption of the amendments in this update is not expected to be material to the Company’s condensed consolidated financial position and results of operations since the amendments require only enhancement of existing income tax disclosures in the notes to the Company’s condensed consolidated financial statements.
