Nature of the Business and Basis of Presentation		1) 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 vision. These functions represent the core underpinnings of both electric and autonomous vehicles, while the advanced user interfaces are transforming the in -cabin Recent Acquisitions On October 1, 2021, indie entered into a definitive agreement and completed its acquisition of ON Design Israel Ltd. (“ON Design Israel”), for $4,974 in cash paid upon close (net of cash acquired), $7,500 of cash in 2022 and up to $7,500 of cash based on design win performance. Upon completion of the acquisition, ON Design Israel was renamed to indie Semiconductor Design Israel Ltd. On October 12, 2021, indie completed its acquisition of all of the outstanding capital stock of TERAXION INC, a Canadian corporation (“TeraXion”) from the existing stockholders of TeraXion. The acquisition was consummated pursuant to a Share Purchase Agreement dated August 27, 2021 (the “Purchase Agreement”). The total consideration paid for this acquisition consisted of (i) approximately $75,282 in cash (including debt paid at closing and net of cash acquired); (ii) the issuance by indie of 5,805,144 On October 21, 2021, indie entered into a definitive agreement with Analog Devices to acquire Symeo GmbH (“Symeo”) for $10,000 in cash at closing, $10,000 in cash in 2023 and an equity -based -out See Note 3 - Business Combinations for additional description of these acquisitions. Reverse Recapitalization with Thunder Bridge Acquisition II On June 10, 2021 (the “Closing Date”), the Company 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. In connection with the Transaction, Thunder Bridge Acquisition II Surviving Pubco, Inc, a Delaware corporation (“Surviving Pubco”), was formed to be the successor public company to TB2, and TB2 was domesticated into a Delaware corporation and merged with and into a merger subsidiary of Surviving Pubco. Immediately prior to the closing of the Transaction (the “Closing”), shareholders of TB2 redeemed an aggregate of 9,877,106 common shares of TB2 and the outstanding common shares and warrants of TB2 were converted into 24,622,894 Class A common shares of Surviving Pubco and 17,250,000 warrants to purchase Class A common shares of Surviving Pubco. The outstanding common shares and warrants of TB2 sponsors were converted into 8,625,000 note (see Note 10 - Warrant Liability). Concurrent with the Closing, TB2 raised $150,000 in a Private Investment in Public Entity (“PIPE”) financing, pursuant to which Surviving Pubco issued 15,000,000 Class A common shares. On the Closing Date, Surviving PubCo changed its name to indie Semiconductor, Inc., and listed its shares of Class A common stock, par value $0.0001 per share (“Common Stock”) on the Nasdaq under the symbol “INDI.” Immediately prior to the Transaction, (i) the Company’s existing warrants to purchase the Company’s Class G units were net exercised and 10,019 Class G units of the Company were issued to the holders of the warrants; (ii) the SAFEs were converted into an aggregate of 284,925 Class A units; (iii) the Embry notes and the interest accrued thereunder were converted into 185,000 Class A units and 100,000 Class C units; and (iv) all 1,251,566 Class C, D, E, F and G units of the Company were converted into Class A units as per their rights and preferences. Immediately thereafter, each outstanding Class A unit and Class B unit was split into approximately 27.8 Class A units and Class B units, respectively (the “Exchange Ratio”). Following the split, 77,497,793 Class A units were exchanged for 43,670,422 Class A common shares and 33,827,371 Class V common shares in indie and 9,564,150 Class B units were exchanged for 9,564,150 Class A common shares in indie (1,791,147 of such shares were subject to vesting conditions). The closing Exchange Ratio was determined by dividing (i) a number of shares of the Company’s Class A common stock equal to (A) the Closing Merger Consideration (as defined below), divided by (B) $10.00 per share, by (ii) the total number of ADK LLC membership units outstanding immediately prior to the Closing. The “Closing Merger Consideration” of $894,628 was determined by taking $900,000 of merger consideration less applicable adjustments of $5,372. 3,450,000 Class A common shares of indie were issued and held in escrow (“Escrow Shares”) for the potential future release to the sponsors of TB2 in the event the earn -out -out -out -Out Immediately following the Closing, the Company’s board of directors consisted of nine directors, seven of whom were designated by the Company. A majority of the directors qualified as independent directors under rules of Nasdaq. The Transaction was accounted for as a reverse recapitalization in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). Under the guidance in Accounting Standards Codifications (“ASC”) Topic 805, indie is treated as the “acquirer” for financial reporting purposes. As such, the Company is deemed the accounting predecessor of the combined business and is the successor registrant for U.S. Securities and Exchange Commission (“SEC”) purposes, meaning that the Company’s financial statements for previous periods will be disclosed in the registrant’s future periodic reports filed with the SEC. The most significant change in our reported financial position and results of operations was gross cash proceeds of $399,511 from the merger transaction, which includes 150,000 in gross proceeds from the PIPE financing that was consummated in conjunction with the Transaction. The increase in cash was offset by transaction costs incurred in connection with the Transaction of approximately $43,463 plus the retirement of indie’s long -term -term The table below summarizes the shares of Class A and Class V common stock issued immediately after the closing of the Transaction as well as the impact of the Transaction on the consolidated statement of stockholders’ equity as of June 10, 2021: Class A Class V Additional Shares Amount Shares Amount Redemption of Class H units (125,101 ) $ — — $ — $ (900 ) Embry notes conversion 8,023,072 1 — — 4,118 Warrants net settlement conversion 278,533 — — — — SAFEs conversion 7,466,891 1 454,077 — 86,099 PIPE and SPAC financing 44,797,894 4 — — 377,654 Earn-out liability — — — — (119,759 ) Transaction expenses — — — — (21,575 ) Warrants liability — — — — (74,408 ) Reverse recapitalization on June 10, 2021 60,441,289 $ 6 454,077 $ — $ 251,229 Risks and Uncertainties The COVID -19 -resistant -19 -19 -19 The Company experienced a decrease in customer demand and product shipments in the second quarter of fiscal year 2020.

Summary of Significant Accounting Policies		2) Summary of Significant Accounting Policies 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 -lived -based -to-cost -party Foreign Currency Certain of the Company’s self -sustaining -U For those foreign subsidiaries where the U.S. dollar is the functional currency, all foreign currency -denominated -denominated Other (income) expense, net -term 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 euro -denominated Other income (expense), net 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 Emerging Growth Company Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”) exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can choose not to take advantage of the extended transition period and comply with the requirements that apply to non -emerging -Combination -affiliates -convertible -year Cash and Cash Equivalents Cash and cash equivalents are defined as short -term 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 PacWest Revolving Line of Credit and accumulated credit limit. 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 16 — Revenue — Concentrations. 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 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 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 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. The Company’s fair value measurements in each reporting period include cash equivalents, debt instruments, share -based -out -out 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 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. 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 Engineering services contracts with customers contain only one distinct performance obligation, which is 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 ICs at agreed upon prices subsequent to completion of ICs design services. The Company has determined that the option to purchase ICs is not a material right and has not allocated transaction price to this provision. For ICs development 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. 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, 2021 and 2020, 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. Cost of Goods Sold Cost of goods sold includes cost of materials and contract manufacturing services, including semiconductor wafers processed by third -party 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 Costs Research and development expenses consist of costs incurred in performing product design and development activities including employee compensation and benefits, third -party -production Selling, General, and Administrative Costs Selling, general, and administrative costs include employee compensation and benefits for sales, executive management, finance, 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. 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 economic conditions in establishing the allowance for doubtful accounts. The Company did not have material write -offs Inventory, Net The Company values inventories at the lower of cost or net realizable value on a first -in -out -in -out -downs -moving -down -downs -downs 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 three seven 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 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 -line Impairment of Long-Lived Assets The Company reviews its long -lived 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 did not record any impairment to long -lived Business Combinations The Company accounts for its business acquisitions under the ASC Topic 805, Business Combinations 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. 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 judgement, including the identification of reporting units, assignment of assets and liabilities to reporting units and the determination of fair value of each reporting unit. Warrant Liability The Company accounts for the public and private placement warrants issued in connection with the Transaction in accordance with ASC 815 -40 Derivatives and Hedging — Contracts in Entity’s Own Equity Fair Value Measurement Other income (expense), net Earn-out Liability The earn -out -out -out -classified -based over time.

Income Taxes 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 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. ADK LLC is treated as a partnership and therefore not subject to U.S. federal and most applicable state and local income tax. Any taxable income or loss generated by ADK LLC and its subsidiaries is passed through to and included in the taxable income or loss of its members, including indie Semiconductor, Inc., based on its economic interest held in ADK LLC.

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, 2021 and 2020, the Company continues to maintain a full valuation allowance against its deferred tax assets. The Company recognizes liabilities for uncertain tax positions based on a two -step The Company records interest and penalties related to unrecognized tax benefits in its tax provision.

Business Combinations		3) Business Combinations The Company acquired City Semiconductor, Inc. (“City Semi”) in May 2020 and both TeraXion and On Design Israel in October 2021. These acquisitions were recorded by allocating the purchase consideration to the net assets acquired based on their estimated fair values at the acquisition date. The excess of the purchase consideration for the acquisition over the fair value of the net assets acquired is recorded as goodwill. The fair values were based on management’s analysis, including work performed by third -party City Semi TeraXion OnDesign Purchase price – cash consideration $ 138 $ 74,050 $ 6,107 Add: debt paid at closing — 6,857 — Less: cash acquired — (5,625 ) (1,133 ) Net cash paid 138 75,282 4,974 Total equity consideration 711 82,441 — Purchase price – accrued cash consideration — — 7,500 Contingent consideration 1,180 — 4,000 Net consideration $ 2,029 $ 157,723 $ 16,474 Fair value of net assets and liabilities assumed: Current assets other than cash — 7,627 119 Property and equipment — 6,009 1,315 Intangible assets – Software license 139 — — Developed technology 369 43,594 5,077 In-progress research & development — 10,304 1,562 Customer relationships — 12,682 — Backlog — 2,378 — Trade name — 6,125 — Other non-current assets — — 66 Current liabilities (177 ) (5,840 ) (754 ) Deferred revenue (41 ) (1,025 ) — Deferred tax liabilities, non-current — (20,272 ) (1,578 ) Other non-current liabilities — — — Long-term debt — (7,580 ) — Total fair value of net assets acquired 290 54,002 5,807 Goodwill $ 1,739 $ 103,721 $ 10,667 Any changes in the estimated fair values of the net assets recorded for the business combination of TeraXion or On Design Israel upon the finalization of more detailed analyses of the facts and circumstances that existed at the date of the transaction will change the allocation of the purchase price. Any subsequent changes to the purchase allocation during the measurement period that are material will be recorded in the reporting period in which the adjustment amounts are determined. Trade receivables and payables, as well as other current and non -current Due to the fact that the acquisitions related to TeraXion and On Design Israel have just recently occurred in the current interim period, the magnitude of the transaction, and the significant information to be obtained and analyzed, some of which resides in foreign jurisdictions, the Company’s fair value estimates for the purchase price allocation are preliminary and may change during the allowable measurement period, which is up to the point the Company obtains and analyzes the information that existed as of the date of the acquisition necessary to determine the fair values of the assets acquired and liabilities assumed, but in no case to exceed more than one year from the date of acquisition. As of April 8, 2022, the Company had not finalized the determination of fair values allocated to various assets and liabilities, including, but not limited to, property, plant and equipment, identifiable intangible assets, other assets, deferred taxes, goodwill, tax uncertainties, income taxes payable, and other liabilities. Specifically for the valuation of intangibles assets acquired, the Company used publicly available benchmarking information, as well as a variety of other assumptions, including market participant assumptions to determine the preliminary values. Any changes in the fair values of the assets acquired and liabilities assumed during the measurement period may result in material adjustments to goodwill. Acquisition of City Semiconductor, Inc On May 13, 2020, the Company acquired certain assets and liabilities of City Semi, which had developed technology related to analog and mixed -signal -speed -to-digital -to -intellectual Total purchase consideration transferred at closing included contingent consideration that had a fair value of $1,180 as of the acquisition date. The maximum contingent consideration payable in connection with the acquisition is $2,000.

The contingent consideration is comprised of two tranches. The first tranche is payable, up to a maximum of $500, upon the achievement of cash collection targets within twelve months of the acquisition, and $456 was achieved in May 2021. The second tranche is payable, up to a maximum of $1,500, upon the shipment of a product incorporating the acquired developed technology. The fair value of any outstanding contingent consideration liabilities will be remeasured as of the end of each reporting period with any resulting remeasurement gains or losses recognized in the consolidated statement of operations. In September 2021, the Company paid off the first tranche of the contingent consideration. The fair value of the second tranche contingent consideration liabilities was $980 as of December 31, 2021. The fair value of the first and second tranche contingent consideration liabilities was $500 and $900, respectively, as of December 31, 2020.

The convertible subordinated notes bore interest of 0.93% per annum, which was compounded annually. The aggregate principal and all accrued and unpaid interest were due in full on December 4, 2017. On December 3, 2017, the Company entered into a 12 -month On December 3, 2018, the Company entered into a 36 -month -month -in -month The amendments to extend the maturity date were treated as modifications of the debt. The convertible subordinated notes with aggregate principal of $2,604 and $1,003 were converted into an aggregate 185,000 Class A units and 100,000 Class C units, respectively, at the investors’ discretion prior to the maturity date or automatically upon a liquidity event, as defined in the loan agreement. The Company determined that the embedded conversion options should not be bifurcated from their host instruments. In December 2020, Embry assigned the notes to its affiliate, Cézanne Investments Ltd. (“Cézanne”). At December 31, 2020, the total carrying value of such convertible subordinated notes payable, net of unamortized discount, was $3,496. Total accrued interest as of December 31, 2020 was $458, and is included in Accrued expenses and other current liabilities PacWest Term Loan and Revolving Line of Credit The Company entered into a loan and security agreement with Pacific Western Bank (“PacWest”, formerly Square 1 Bank) in January 2015, that provided a term loan of up to $10,000 with a maturity date of September 2020. The term loan bore interest equal to the greater of one percent above the prime rate in effect, or 4.5% on outstanding borrowings. In addition, the loan and security agreement provided for a revolving line of credit. The revolving line of credit bore interest equal to the greater of seventy -five During 2020, the Company entered into three amendments to the PacWest loan agreement. Pursuant to the terms of the amendments, $889, the full amount of unpaid principal and interest was transferred from the PacWest term loan to the revolving line of credit as of January 30, 2020. In addition, the amendments modified certain financial covenants, including that the Company maintain a minimum cash balance of $2,300 and adjusted the borrowing limits to $2,000. As of December 31, 2021 and 2020, the Company had no outstanding balance on the term loan. As of December 31, 2021 and 2020, the revolving line of credit had an outstanding balance of zero and $1,675, respectively. The Company’s borrowings under the term loan and revolving line of credit were subject to an aggregate borrowing limit of $20,000 and $2,000 as of December 31, 2021 and 2020, respectively. Total borrowings at any given time under the line of credit are limited to a percentage of domestic accounts receivables less than 90 days past due and other factors. The revolving line of credit is subject to debt covenants which, if violated, could result in the outstanding balance becoming immediately due. The Company has complied with or obtained waivers for all such covenants as of the date these financial statements were issued. On November 5, 2021, the Company entered into an amendment to the PacWest loan agreement that (i) increased the maximum borrowing capacity under the revolving line of credit to $20,000, (ii) limited the security interests of the bank to the cash collateral set at 102.5% of the drawn amount of the loan, (iii) removed various reporting and restrictive covenants, (iv) extended the maturity date to November 4, 2022 and (iv) reduced the interest rate to 2.1% per annum. In addition, the amendment requires the Company to collateralize a cash balance equal to the total outstanding balance in a cash security account with PacWest. Upon execution of the amendment, the Company repaid the outstanding balance of $1,675 under the original line of credit to this new arrangement. Trinity Term Loan In March 2018, the Company entered into a term loan agreement with Trinity Capital Fund (“Trinity”) to borrow $15,000 at a rate of 11.25% per annum. In connection with such loan, the Company issued a warrant to Trinity to acquire 6,250 Class G units at an exercise price per unit of $35.42 In October 2020, the Company entered into a new loan agreement with Trinity, which replaced the March 2018 agreement. The new loan had a principal of $12,000, which was exchanged for the old loan’s principal balance of $11,325, lender fees of $474 and a cash payment to the Company of $194. In addition, the Company issued to Trinity 1,844 additional warrants to purchase the Company’s Class G units, which had a fair value of $405. The new loan agreement was treated as a modification for accounting purposes. The unamortized discount from the old loan was treated as additional debt discount on the new loan along with the lender fees paid to and additional warrants issued to Trinity in October 2020.

In May 2020, the loan was approved, and the Company received gross proceeds from the loan in the amount of $1,868 (the “PPP Loan”). The PPP Loan took the form of a promissory note that matures two years after the date of the note and bears interest at a rate of 1.0% per annum. Monthly principal and interest payments, less the amount of any potential forgiveness (discussed below), will commence in 2021. The PPP Loan provides for customary events of default, including, among others, those relating to failure to make payments thereunder. The Company may prepay the principal of the PPP Loan at any time without incurring any prepayment penalties. The PPP Loan is non -recourse All or a portion of the PPP Loan may be forgiven by the SBA and lender upon application by the Company and upon documentation of expenditures in accordance with the SBA requirements. Under the CARES Act, loan forgiveness is available for the sum of documented payroll costs, covered rent payments, and covered utilities during the applicable period beginning on the date of loan approval. For purposes of the CARES Act, payroll costs exclude compensation of an individual employee in excess of $100,000, prorated annually. Not more than 25% of the forgiven amount may be for non -payroll -time On May 10, 2021, the entire balance of the PPP Loan was forgiven by the SBA and lender. As a result, the Company recorded a gain on extinguishment of debt of $1,889, which represented the principal balance of $1,868 and accrued interest of $21, in the consolidated statement of operations for the year ended December 31, 2021.

The repayment of monthly installments reduces the credit limit over time. At December 31, 2021 the outstanding principal balance and credit limit of the loan was $7,102 or CAD8,976. This loan is secured with an authorized credit facility of CAD7,000 from the bank, bearing interest at prime rate plus 0.25%. This line of credit was unused at December 31, 2021.

Fair Value Measurements		13) Fair Value Measurements The Company’s debt instruments are recorded at their carrying values in its consolidated balance sheets, which may differ from their respective fair values. The fair values of the Company’s convertible notes are estimated using the valuation of the securities into which the debt is convertible, external pricing data, based on interest rates and credit ratings for similar issuances with the same remaining term as the Company’s outstanding borrowings. The fair value of the Embry convertible notes was determined using valuation inputs categorized as Level 3. The fair values of the Company’s term loans and Tropez note generally approximated their carrying values.

In connection with entering into the term loan agreement with Trinity in March 2018, the Company issued an aggregate of 6,250 warrants with a strike price of $35.42 to purchase Class G units. In April 2018, as part of an amendment to the loan and security agreement, the Company issued warrants to PacWest to purchase 3,388 Class G units with a strike price of $35.42 (see Note 21 — Commitments and Contingencies). On October 1, 2020, in connection with the new loan agreement with Trinity, the Company issued additional warrants to Trinity to purchase 1,844 Class G units at a strike price of $35.42 under the same terms and features as previously issued Class G warrants. Following the Company’s announcement of the Master Transactions Agreement (“MTA”), PacWest issued a letter dated February 3, 2021 to the Company demanding 52,632 warrants in satisfaction of the provisions contained in the August 9, 2017 credit facility amendment.

In June 2018, the Company issued 492,110 Class F units to investors at an issue price of $54.87 per unit for cash consideration of $26,790, net of issuance costs of $210. In May 2020, the Company issued 4,500 Class H units to the owners of City Semi as part of the business combination, see Note 3 — Business Combinations. The rights and privileges of the holders of the equity units are as follows: Liquidation Rights and Distributions with Respect to Liquidity Event Rights The Company’s Operating Agreement outlines the liquidation and other preferential rights granted to holders of Class C, D, E, F, G and H units. These rights include preferential treatment in the case of an extraordinary distribution by the Company to its members (not including any distribution of units), a sale of the Company, a liquidation event or unwind of the Company. The distribution provisions are complex and depend on the amount of proceeds to be distributed. In the scenario where the proceeds are sufficient to return the capital investment of each class and provide greater than another 50% of the capital investment of each class on a participating basis, then Class F as the most senior preference and would be entitled to the amount of the original issue price of the Class F Units, followed by Classes E, D, and C in that order, each in the respective amount of the original issue price of its units, followed by Class H and G up to the original issue price. The remaining amounts available to be distributed are shared among all of the classes of Units (except for Class G) according to their fully diluted percentages. If distribution proceeds are not sufficient to return the capital investment of each class and provide greater than another 50% of the capital investment of each class on a participating basis, then, the Operating Agreement provides numerous distribution waterfalls that are designed to achieve the rights of each class in each scenario based on the specific amount of proceeds. Generally, if a preferred class would receive through a fixed preference of 150% of its capital as compared to 100% of its capital plus its participation in the residual tranche, then the preferred class would receive up to 150% of its capital with no participation. Class A and Class B receive distributions only in the residual tranche to the extent proceeds remain after the preferences. Conversion Rights Each unit of Classes C, D, E, F, G and H shall be convertible, at the option of the holder thereof, into such number of fully paid and nonassessable Class A units as is determined by dividing the original issue price for the units of Classes C, D, E, F, G or H as applicable, by the conversion price (original issue price) applicable to such Class C, D, E, F, G and H unit in effect on the conversion date. Additionally, each Class C, D, E, F, G, or H unit shall automatically be converted into Class A units at the Conversion Price applicable to such units of Classes C, D, E, F, G or H immediately upon the Company’s sale of its securities in a firm commitment underwritten public offering pursuant to a registration statement under the Securities Act in which (i) the public offering per unit price is not less than $180.53 (adjusted for splits and reverse splits and other adjustments of Class F Units) and (ii) the anticipated aggregate offering price is at least $200,000. The conversion price shall be the initial issuance price as adjusted for any antidilution provisions as defined in the operating agreement. Voting Rights Each Class A unit shall be entitled to one point four seven (1.47) votes per Class A unit. This ratio is revised from time to time to equal (X) divided by (Y), where (X) equals the sum of (i) the Class A units issued to the initial members and their successors and assigns plus (ii) the total number of authorized B units and G units, and (Y) equals the total number of Class A units issued to the initial members and their successors and assigns. Holders of Class B units shall not be entitled to vote except as otherwise required by law. Each holder of Class C, D, E, and F units shall be entitled one vote per Class A unit into which such Class C, D, E, and F units are convertible. Holders of Class G and H units shall not be entitled to vote except as otherwise required by law or in the event the holders of Class G or H units convert their units to Class A units as in the operating agreement.

The Transaction materially impacted the number of shares outstanding. Weighted average shares outstanding in the table above have been retroactively restated to give effect to the reverse recapitalization. See Note 1 - Nature of Business and Basis of Presentation for more information regarding the Transaction. The Company’s potentially dilutive securities, which include SAFEs, unvested Class B units, unvested restricted stock units, preferred units, warrants for Class A units, warrants for Class G units, and convertible debt, have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share. For the years ended December 31, 2021 and 2020 the weighted average number of shares outstanding used to calculate both basic and diluted net loss per share attributable to common shares is the same because the Company reported a net loss for each of these periods and the effect of inclusion would be antidilutive. The Company excluded the following potential shares, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share attributable to stockholders for the periods indicated because including them would have had an antidilutive effect: Year Ended December 31, 2021 2020 SAFEs — 4,711,711 Unvested Class B units 1,612,797 3,841,856 Unvested Phantom units 1,188,862 — Unvested Restricted stock units 3,869,848 — Convertible preferred units — 35,935,292 Warrants to purchase Class G units — 267,939 Convertible debt into Class A and preferred units — 285,000 Convertible Class V common shares 30,448,081 — Public warrants for the purchase of Class A common shares 17,250,000 — Private warrants for the purchase of Class A common shares 10,150,000 — Earn-out Shares 10,000,000 — Escrow Shares 1,725,000 — 76,244,588 45,041,798

The Company has concluded that it is not possible to reasonably quantify future taxable income. Further, when considering its history of generating net operating losses, management concluded that it is more likely than not that some or all of the Company’s domestic deferred assets will not be realized and has established a full valuation allowance for U.S. domestic deferred tax assets. A similar conclusion regarding China and Hong Kong operations conducted through Wuxi and its subsidiaries have been reached. As a result, the Company continues to maintain a full valuation allowance as of December 31, 2021 and 2020 for its China operations. The Company’s net deferred tax liability position is the result of the UK, Israel and Canada operations. The Company does not provide for foreign income and withholding, U.S. Federal, or state income taxes expense or tax benefits for the difference between the financial reporting basis over the tax basis of its investments in foreign subsidiaries to the extent such amounts are indefinitely reinvested to support operations and continued growth plans outside the U.S. The Company reviews its indefinite reinvestment assertion on a quarterly basis and evaluates its plans for reinvestment. This includes a review of the Company’s ability to control repatriation, its ability to mobilize funds without triggering basis differences, and the profitability of U.S. operations, their cash requirements and the need, if any, to repatriate funds.

A tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, on the basis of the technical merits. The Company records tax positions as liabilities and adjusts these liabilities when its judgement changes as a result of the evaluation of new information not previously available. Because of the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from the Company’s current estimate of the recognized tax benefit liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which new information is available. As of December 31, 2021 and 2020, the Company has not recorded any uncertain tax positions in its financial statements. The Company records interest and penalties related to unrecognized tax benefits in provision of income taxes. As of December 31, 2021 and 2020, no accrued interest or penalties are recorded in the consolidated balance sheets, and the Company has not recorded any related expenses. The Company files tax returns as prescribed by the tax laws of the jurisdictions in which it operates and is subject to examinations by the various jurisdictions where applicable. There are currently no pending tax examinations. The Company’s tax years are still open under statute from 2018 to 2020 for Federal purposes and from 2017 to 2020 for California. Foreign tax statutes are generally three to five years. The company’s significant foreign taxing jurisdiction are Canada, UK, Hungary, China and Israel.

In addition, a three -tiered 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 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 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. The Company’s fair value measurements in each reporting period include cash equivalents, debt instruments, share -based -out -out
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 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. 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 Engineering services contracts with customers contain only one distinct performance obligation, which is 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 ICs at agreed upon prices subsequent to completion of ICs design services. The Company has determined that the option to purchase ICs is not a material right and has not allocated transaction price to this provision. For ICs development 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. 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, 2021 and 2020, 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.
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 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 Costs		Research and Development Costs Research and development expenses consist of costs incurred in performing product design and development activities including employee compensation and benefits, third -party -production
Selling, General, and Administrative Costs		Selling, General, and Administrative Costs Selling, general, and administrative costs include employee compensation and benefits for sales, executive management, finance, 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.
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 economic conditions in establishing the allowance for doubtful accounts. The Company did not have material write -offs

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 three seven 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
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.

Impairment of Long-Lived Assets		Impairment of Long-Lived Assets The Company reviews its long -lived 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 did not record any impairment to long -lived
Business Combinations		Business Combinations The Company accounts for its business acquisitions under the ASC Topic 805, Business Combinations
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. 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 judgement, including the identification of reporting units, assignment of assets and liabilities to reporting units and the determination of fair value of each reporting unit.

Income Taxes		Income Taxes 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 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. ADK LLC is treated as a partnership and therefore not subject to U.S. federal and most applicable state and local income tax. Any taxable income or loss generated by ADK LLC and its subsidiaries is passed through to and included in the taxable income or loss of its members, including indie Semiconductor, Inc., based on its economic interest held in ADK LLC. 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 -US 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, 2021 and 2020, the Company continues to maintain a full valuation allowance against its deferred tax assets. The Company recognizes liabilities for uncertain tax positions based on a two -step The Company records interest and penalties related to unrecognized tax benefits in its tax provision. As of December 31, 2021 and 2020, no accrued interest or penalties are recorded on the consolidated balance sheet, and the Company has not recorded any related expenses.
