PROSPECTUS SUMMARY

This summary highlights selected information appearing elsewhere in this prospectus. Because it is a summary, it may not contain all of the information that may be important to you. To understand this offering fully, you should read this entire prospectus, the registration statement of which this prospectus is a part carefully, including the information set forth under the heading “Risk Factors” and our financial statements.

The Company

indie offers highly innovative automotive semiconductors and software solutions for Advanced Driver Assistance Systems (“ADAS”), including LiDAR, connected car, user experience and electrification applications. 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 we rely on every day. indie is an approved vendor to Tier 1 automotive suppliers and its platforms can be found in marquee automotive OEMs around the world. Headquartered in Aliso Viejo, California, indie has design centers and sales offices in Austin, Texas; Boston, Massachusetts; Detroit, Michigan; San Francisco and San Jose, California; Budapest, Hungary; Dresden, Germany; Edinburgh, Scotland; and several locations throughout China.

Background

On June10, 2021, Thunder Bridge II domesticated into a Delaware corporation and consummated a series of transactions that resulted in the combination (the “Business Combination”) of Thunder Bridge II with Ay Dee Kay, LLC d/b/a indie Semiconductor (“ADK LLC”) pursuant to a Master Transactions Agreement, dated December14, 2020, as amended on May3, 2021, by and among Thunder Bridge II, Thunder Bridge II Surviving Pubco, Inc. (“Surviving Pubco”), ADK LLC, and the other parties named therein, following the approval at the extraordinary general meeting of the shareholders of Thunder Bridge II held on June9, 2021 (the “Special Meeting”).

On December14, 2020, Thunder Bridge II entered into subscription agreements (the “Subscription Agreements”) with the investors named therein (the “PIPE Investors”), including Mr.Kight and an affiliate of the Sponsor, pursuant to which Thunder Bridge II agreed to issue and sell to the PIPE Investors an aggregate of 15,000,000 of Thunder Bridge II Class A ordinary shares, at a price of $10.00 per Class A ordinary share, simultaneously with or immediately prior to the Closing (the “PIPE Financing”). Upon the closing of the Business Combination, the shares issued pursuant to the PIPE Financing were automatically exchanged for 15,000,000shares of our Class A common stock (the “PIPE Shares”). Effective upon the closing of the Business Combination, Surviving Pubco changed its name to indie Semiconductor, Inc.

Our Class A common stock and our public warrants are currently traded on Nasdaq under the symbols “INDI” and “INDIW,” respectively.

The rights of holders of our Class A common stock and warrants are governed by our amended and restated certificate of incorporation, our bylaws and the Delaware General Corporation Law (the “DGCL”), and in the case of the warrants, the Warrant Agreement, dated August8, 2019, by and between Thunder Bridge II and Continental Stock Transfer & Trust Company, as amended by the Assignment, Assumption and Amendment Agreement, dated as of June10, 2021, by and among Thunder Bridge II, Surviving Pubco and Continental Stock Transfer & Trust Company (as amended, the “Warrant Agreement”). See the sections entitled “Description of Securities” and “Selling Securityholders — Certain Relationships with the Selling Securityholders.”

Implications of Being an Emerging Growth Company

We are an “emerging growth company” as defined in Section 2(a) of the Securities Act of 1933, as amended (the “Securities Act”), as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). As an emerging growth company, we may benefit from specified reduced disclosure and other requirements that are otherwise applicable generally to public companies. These provisions include:

•        presentation of only two years of audited financial statements and only two years of related management’s discussion and analysis of financial condition and results of operations in this prospectus;

•        reduced disclosure about our executive compensation arrangements;

1

•        no non-binding stockholder advisory votes on executive compensation or golden parachute arrangements;

•        exemption from any requirement of the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (i.e., an auditor discussion and analysis); and

•        exemption from the auditor attestation requirement in the assessment of our internal control over financial reporting.

We may benefit from these exemptions until December31, 2024 or such earlier time that we are no longer an emerging growth company. We will cease to be an emerging growth company upon the earliest of: (1) December31, 2024; (2) the first fiscal year after our annual gross revenues are $1.07billion or more; (3) the date on which we have, during the previous three-year period, issued more than $1.0billion in non-convertible debt securities; or (4) the date on which we are deemed to be a “large accelerated filer” under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We may choose to benefit from some but not all of these reduced disclosure obligations in future filings. If we do, the information that we provide stockholders may be different than you might get from other public companies in which you hold stock.

Summary of Risks

An investment in shares of our Class A common stock and warrants involves substantial risks and uncertainties that may adversely affect the value of your investment. Some of the more significant challenges and risks relating to an investment in our company include, among other things, the following:

Risks Related to Our Operations and Industry

•        The cyclical nature of the semiconductor industry may limit our ability to maintain or improve our net sales and profitability.

•        The semiconductor industry is highly competitive. If we fail to introduce new technologies and products in a timely manner, it could adversely affect business.

•        The average selling prices of products in our markets have historically decreased over time and could do so in the future, which could adversely impact our revenue and profitability.

•        Much of our business depends on winning competitive bid selection processes, and the failure to be selected could adversely affect business in those market segments.

•        The demand for our products depends to a significant degree on the demand for our customers’ end products.

•        Our sales are made primarily to Tier 1 suppliers. Any downturn in the automotive market could significantly harm our financial results.

•        Our business could suffer from third-party manufacturing problems, which could reduce our yield, margins and adversely impact our business and profitability.

•        We rely on the timely supply of materials and could suffer if suppliers fail to meet their delivery obligations or raise prices. Certain materials needed in our manufacturing operations are only available from a limited number of suppliers.

•        We may be unsuccessful in developing and selling new products with profit margins similar to or better than what we have experienced in the past, which would impact our overall financial performance.

•        The semiconductor industry is characterized by continued price erosion, especially after a product has been on the market for a period of time.

2

•        We may pursue mergers, acquisitions, investments and joint ventures, which could adversely affect our results of operations.

•        We may seek additional capital to take advantage of business opportunities and support the further expansion of our business, which may result in dilution to our stockholders.

•        From time to time, we may rely on strategic partnerships, joint ventures and alliances for manufacturing and research and development. However, we do not control these partnerships and joint ventures, and actions taken by any of our partners or the termination of these partnerships or joint ventures could adversely affect our business.

•        We may from time to time desire to exit certain programs or businesses, or to restructure our operations, but may not be successful in doing so.

•        Disruptions in our relationships with any one of our key customers could adversely affect our business.

•        Conflict minerals disclosure regulations may require us to incur additional expenses, may result in damage to our business reputation and may adversely impact our ability to conduct our business.

Risks Related to Our Organizational Structure

•        We are a holding company and our only material asset is our interest in ADK LLC, and we are accordingly dependent upon distributions made by our subsidiaries to pay taxes, make payments under the Tax Receivable Agreement and pay dividends.

•        Under the Tax Receivable Agreement, we will be required to pay 85% of the tax benefits relating to tax depreciation or amortization deductions as a result of the tax basis step-up we receive in connection with the exchanges of LLC Units into our Class A common stock and related transactions, and those payments may be substantial. In certain cases, payments under the Tax Receivable Agreement may exceed the actual tax benefits we realize or may be accelerated.

Risks Related to Macroeconomic Conditions

•        Downturns or volatility in general economic conditions could have a material adverse effect on our business, financial condition, results of operations and liquidity

•        Fluctuations in foreign exchange rates could decrease revenues, increase operating costs and have an adverse effect on our results of operations.

•        Our worldwide operations are subject to political, economic and health risks and natural disasters, which could have a material adverse effect on our business operations.

Risks Related to our Intellectual Property, Technology and Cybersecurity.

•        We rely to a significant extent on proprietary intellectual property and may not be able to protect this intellectual property against improper use by our competitors or others.

•        We may become party to intellectual property claims or litigation that could cause us to incur substantial costs, pay substantial damages or prohibit us from selling our products.

•        Certain software that we use in our products is licensed from third parties and may not be availableto us in the future, which may delay product development and production or cause us to incur additional expense.

•        Interruptions in information technology systems could adversely affect business.

•        Our computer systems and networks are subject to attempted security breaches and other cybersecurity incidents, which, if successful, could be costly and could impact our business.

3

Risks Related to Regulatory Compliance and Legal Matters

•        Our failure to comply with the large body of laws and regulations to which we are subject could have a material adverse effect on our business and operations.

•        Our business may be adversely affected by costs relating to product defects, and we could be faced with product liability claims.

•        We may face significant warranty claims, which could be expense and adversely impact our business and results of operations.

•        Significant litigation could impair our reputation and cause us to incur substantial costs.

•        Our business and operations could be negatively affected if we become subject to any securities litigation or stockholder activism, which could cause us to incur significant expense, hinder execution of business and growth strategy and impact our stock price.

•        We are subject to export restrictions and laws affecting trade and investments that could materially and adversely affect our business and results of operations.

•        We could be subject to domestic or international changes in tax rates or the adoption of new tax legislation, or we could otherwise have exposure to additional tax liabilities, which could adversely affect our results of operations or financial condition.

•        We could be adversely affected by violations of applicable anti-corruption laws or violations of our internal policies designed to ensure ethical business practices.

•        In order to comply with environmental and occupational health and safety laws and regulations, we may need to modify our activities or incur substantial costs, and such laws and regulations, including any failure to comply with such laws and regulations, could subject us to substantial costs, liabilities, obligations and fines, or require us to have suppliers alter their processes.

Risks Related to Financial Reporting, Internal Controls and Being a Public Company

•        The unaudited pro forma financial information included in the section entitled “Unaudited Pro Forma Condensed Combined Financial Information” may not be representative of our results after the Business Combination.

•        Inadequate internal controls could result in inaccurate financial reporting.

•        We may not be able to timely and effectively implement and maintain controls and procedures required by Section 404 of the Sarbanes-Oxley Act that are applicable to us.

•        We will incur significant increased expenses and administrative burdens as a public company, which could have a material adverse effect on our business, financial condition and results of operations.

•        We qualify as an “emerging growth company” within the meaning of the Securities Act, and if we take advantage of certain exemptions from disclosure requirements available to emerging growth companies, we could make our securities less attractive to investors and may make it more difficult to compare our performance to the performance of other public companies.

•        Our actual operating results may differ significantly from our guidance.

Risks Related to Ownership of Our Class A Common Stock and Warrants, and Organizational Documents

•        There can be no assurance we will be able to comply with the continued listing standards of Nasdaq for our Class A common stock.

•        We may redeem your unexpired warrants prior to their exercise at a time that is disadvantageous to you, thereby making your warrants worthless.

4

•        Our warrants may have an adverse effect on the market price of our Class A common stock.

•        You may be diluted by the future issuance of additional Class A common stock or LLC Units in connection with our incentive plans, acquisitions or otherwise.

•        There may be sales of a substantial amount of Class A common stock by our stockholders and these sales could cause the price of our securities to fall.

•        Delaware law and our Certificate of Incorporation and Bylaws contain certain provisions, including anti-takeover provisions, that limit the ability of stockholders to take certain actions and could delay or discourage takeover attempts that stockholders may consider favorable.

•        Our Certificate of Incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or other employees.

General Risk Factors

•        The market price of our securities may fluctuate or decline

•        Loss of key management or other highly skilled personnel, or an inability to attract such management and other personnel, could adversely affect our business.

•        Our operating results are subject to substantial quarterly and annual fluctuations.

Please see “Risk Factors” for a discussion of these and other factors you should consider before making an investment in our securities.

RISK FACTORS

The following risk factors apply to our business and operations. These risk factors are not exhaustive, and investors are encouraged to perform their own investigation with respect to our business, financial condition and prospects. You should carefully consider the following risk factors in addition to the other information included in this prospectus, including matters addressed in the section entitled “Cautionary Note Regarding Forward-Looking Statements.” We may face additional risks and uncertainties that are not presently known to us, or that we currently deem immaterial, which may also impair our business or financial condition. The following discussion should be read in conjunction with the financial statements and notes to the financial statements included herein.

Risks Related to Our Operations and Industry

The cyclical nature of the semiconductor industry may limit our ability to maintain or improve our net sales and profitability.

The semiconductor industry is highly cyclical and is prone to significant downturns from time to time. Cyclical downturns can result in substantial declines in semiconductor demand, production overcapacity, high inventory levels and accelerated erosion of average selling prices. Such downturns result from a variety of market forces including constant and rapid technological change, quick product obsolescence, price erosion, evolving standards, short product life cycles and wide fluctuations in product supply and demand.

Recently, downturns in the semiconductor industry have been attributed to a variety of factors including the current COVID-19 pandemic, ongoing trade disputes between the United States and China, weakness in demand and pricing for semiconductors across applications, and excess inventory. These downturns have directly impacted our business, suppliers, distributors and customers.

Conversely, significant upturns could cause us to be unable to satisfy demand in a timely and cost-efficient manner, and could result in increased competition for access to third-party foundry, assembly and testing capacity. In the event of such an upturn, we may not be able to expand our workforce and operations in a sufficiently timely manner, procure adequate resources and raw materials, or locate suitable suppliers or other subcontractors to respond effectively to changes in demand for our existing products or to the demand for new products. Accordingly, our business, financial condition and results of operations could be materially and adversely affected.

The semiconductor industry is highly competitive. If we fail to introduce new technologies and products in a timely manner, it could adversely affect business.

The semiconductor industry is highly competitive and characterized by constant and rapid technological change, short product lifecycles, significant price erosion, and evolving standards for quality. Accordingly, the success of our business depends, to a large extent, on our ability to meet evolving industry requirements and introduce new products and technologies, both in a timely manner and at prices that are acceptable to customers.

Moreover, the costs related to the research and development necessary to develop new technologies and products are significant and some of our competitors may have greater resources than us. If they significantly increase the resources that they devote to developing and marketing their products, we may not be able to compete effectively.

Further, industry consolidation could enhance competitors’ product offerings and financial resources, strengthening their competitive position.

As a result of these competitive pressures, we may face declining sales volumes or lower prices for our products, and may not be able to reduce total costs in line with declining revenue. If any of these risks materialize, they could have a material adverse effect on our business, financial condition and results of operations.

The average selling prices of products in our markets have historically decreased over time and could do so in the future, which could adversely impact our revenue and profitability.

Average selling prices of semiconductor products in the markets we serve have historically decreased over time. Profit margins and financial results may suffer if we are unable to offset any reductions in average selling prices by reducing costs, developing new or enhanced products on a timely basis with higher selling prices or profit margins, or increasing sales volumes. Although we have contractual agreements with customers, there is no assurance that those price agreements will be honored. As a result, our average selling prices may decline faster than forecasted.

8

Much of our business depends on winning competitive bid selection processes, and the failure to be selected could adversely affect business in those market segments.

The competitive selection processes often require an investment of significant time and capital resources, with no guarantee of winning the contract and generating revenue. In the automotive semiconductor market in which we compete, due to the longer design cycles involved, failure to win a design-in could prevent access to a customer for several years. Our failure to win a significant number of these bids could result in reduced revenues, and hurt our competitive position for future selection processes, which could have a material adverse effect on our business, financial condition and results of operations.

The demand for our products depends to a significant degree on the demand for our customers’ end products.

The vast majority of our revenue is derived from sales to manufacturers in the automotive industry. Demand in this market fluctuates significantly, driven by consumer spending, consumer preferences, the development of new technologies and prevailing economic conditions. In addition, the end products in which our semiconductors are incorporated may not be successful, or may experience price erosion or other competitive factors that could affect the price manufacturers are willing to pay. Such customers have in the past, and may in the future, vary order levels significantly from period to period, request postponements of scheduled delivery dates, modify their orders or reduce lead times. This is particularly common during periods of low demand. This can make managing business difficult, as it limits the predictability of future revenue. It can also affect the accuracy of our financial forecasts.

Furthermore, developing industry trends, including customers’ use of outsourcing and new and revised supply chain models, may affect our revenue, costs and working capital requirements.

Our sales are made primarily to Tier 1 suppliers. Any downturn in the automotive market could significantly harm our financial results.

This automotive concentration of sales exposes us to the risks associated with the automotive market. For example, our anticipated future growth is highly dependent on the adoption of ADAS, user interface, connectivity and electrification technologies, which are expected to have increased sensor and power product content. A downturn in the automotive market could delay automakers’ plans to introduce new vehicles with these features, which would negatively impact the demand for products and our ability to grow our business.

The automotive industry continues to undergo consolidation and reorganization. Further, such changes in the automotive market could have a material adverse effect on our business, financial condition and results of operations.

Moreover, recent governmental actions to contain the spread of the COVID-19 pandemic have adversely affected the automotive industry, including manufacturers, dealers, distributors and third-party suppliers. For example, many automotive manufacturers were forced to suspend manufacturing operations and have only recently resumed production. While demand in the automotive industry is dependent on a number of factors, automotive manufacturers expect the impact of the COVID-19 pandemic to be highly dependent on its duration and severity.

The foregoing operational and economic impacts and other adverse effects on the automotive industry could have a material adverse effect on our business, financial condition and results of operations.

Our business could suffer from third-party manufacturing problems.

The manufacture of our products, including the fabrication of semiconductor wafers, and the assembly and testing of our products, involve highly complex processes. For example, minute levels of contaminants in the manufacturing environment, difficulties in the wafer fabrication process or other factors can cause a substantial portion of the components on a wafer to be nonfunctional. These problems may be difficult to detect at an early stage of the manufacturing process and often are time-consuming and expensive to correct.

From time to time, we have experienced problems achieving acceptable yields at our third-party wafer fabrication partners, resulting in delays in the availability of components. Moreover, an increase in the rejection rate of products during the quality control process before, during or after manufacture and/or shipping of such products, results in lower yields and margins.

9

In addition, changes in manufacturing processes required as a result of changes in product specifications, changing customer needs and the introduction of new product lines have historically significantly reduced manufacturing yields, resulting in low or negative margins on those products. Poor manufacturing yields over a prolonged period of time could adversely affect our ability to deliver products on a timely basis and harm relationships with our customers, which could materially and adversely affect our business, financial condition and results of operations.

We rely on the timely supply of materials and could suffer if suppliers fail to meet their delivery obligations or raise prices. Certain materials needed in our manufacturing operations are only available from a limited number of suppliers.

Our manufacturing operations depend on deliveries of materials in a timely manner and, in some cases, on a just-in-time basis. From time to time, suppliers may extend lead times, limit the amounts supplied or increase prices due to capacity constraints or other factors. Supply disruptions may also occur due to shortages in critical materials or components. Because our products are complex, it is frequently difficult or impossible to substitute one type of material with another. A failure by suppliers to deliver requirements could result in disruptions to our third-party manufacturing operations. Our business, financial condition and results of operations could be harmed if we are unable to obtain adequate supplies of materials in a timely manner or if there are significant increases in the costs of materials.

We may be unsuccessful in developing and selling new products with profit margins similar to or better than what we have experienced in the past, which would impact our overall financial performance.

Should we fail to improve our profit margin in the future, and accordingly develop and introduce sufficiently unique products, our business, financial condition and results of operations could be materially and adversely affected.

The semiconductor industry is characterized by continued price erosion, especially after a product has been on the market for a period of time.

One of the results of the rapid innovation in the semiconductor industry is that pricing pressure, especially on products containing older technology, can be intense. Product life cycles are relatively short, and as a result, products tend to be replaced by more technologically advanced substitutes on a regular basis. In turn, demand for older technology falls, causing the price at which such products can be sold to drop, in some cases precipitously.

In order to continue profitably supplying these products, we must reduce our product costs in line with the lower revenue we can expect to generate. Usually, this must be accomplished through improvements in process technology and production efficiencies. If we cannot advance our process technologies or improve our efficiencies to a degree sufficient to maintain required margins, we will no longer be able to make a profit from the sale of these products. Moreover, we may not be able to cease production of such products, either due to contractual obligations or for customer relationship reasons, and as a result we may be required to bear a loss on such products. We cannot guarantee that competition in our core product markets will not lead to price erosion, lower revenue or lower margins in the future. Should reductions in our manufacturing costs fail to keep pace with reductions in market prices for the products we sell, this could have a material adverse effect on our business, financial condition and results of operations.

We may pursue mergers, acquisitions, investments and joint ventures, which could adversely affect our results of operations.

Our growth strategy includes acquiring or investing in businesses that offer complementary products, services and technologies, or enhance our market coverage or technological capabilities. Any acquisitions we may undertake and their integration involve risks and uncertainties. There could be unexpected delays, challenges and related expenses, and disruption of our business. Inaccuracies in our estimates and assumptions used to assess a transaction may result in us not realizing the expected financial or strategic benefits of any such transaction. In addition, U.S. and foreign regulatory approvals required in connection with an acquisition may take longer than anticipated to obtain, may not be forthcoming or may contain burdensome conditions, which may jeopardize, delay or reduce the anticipated benefits to us of the transaction.

10

We may seek additional capital to take advantage of business opportunities and support the further expansion of our business, which capital might not be available on acceptable terms, if at all, or may result in dilution to our stockholders.

While we believe that the net proceeds from the Business Combination will be sufficient to meet our current capital requirements, we may seek additional equity or debt financing to pursue strategic opportunities, acquire complementary businesses, products or technologies or to fund the further expansion of our business. If additional funds are raised through the issuance of equity or debt securities, the percentage ownership of our existing stockholders would be reduced, and such securities may have rights, preferences or privileges senior to those of the holders of our Class A common stock.

From time to time, we may rely on strategic partnerships, joint ventures and alliances for manufacturing and research and development. However, we do not control these partnerships and joint ventures, and actions taken by any of our partners or the termination of these partnerships or joint ventures could adversely affect our business.

As part of our strategy, we may enter into a number of long-term strategic partnerships and alliances, including mergers and acquisitions. There can be no assurances that they will be successful. If any of our current strategic partners or alliances we may engage with in the future were to encounter financial difficulties or change their business strategies, they may no longer be able or willing to participate in these groups or alliances, which could have a material adverse effect on our business, financial condition and results of operations.

We may from time to time desire to exit certain programs or businesses, or to restructure our operations, but may not be successful in doing so.

From time to time, we may decide to divest certain businesses or restructure our operations, including through the contribution of assets to joint ventures. However, our ability to successfully exit businesses, or to close or consolidate operations, depends on a number of factors, many of which are outside of our control. For example, if we are seeking a buyer for a particular business, none may be available, or we may not be successful in negotiating satisfactory terms with prospective buyers. In some cases, particularly with respect to European operations, there may be laws or other legal impediments affecting our ability to carry out such sales or restructuring.

If we are unable to exit a business in a timely manner, or to restructure our operations in a manner we deem to be advantageous, this could have a material adverse effect on our business, financial condition and results of operations. Even if a divestment is successful, we may face indemnity and other liability claims by the acquirer or other parties.

Disruptions in our relationships with any one of our key customers could adversely affect our business.

A substantial portion of our revenue is derived from top customers. We cannot guarantee that we will be able to generate similar levels of revenue from our largest customers in the future. If one or more of these customers substantially reduces its purchases from us, it could have a material adverse effect on our business, financial condition and results of operations. Sales to Aptiv, a leading Tier 1 automotive supplier, represented approximately 61%, 57% and 77% of our total revenue for the three months ended March31, 2021 and the years ended December31, 2020 and 2019, respectively. The loss of this customer would have a material impact on our consolidated financial results.

Conflict minerals disclosure regulations may require us to incur additional expenses, may result in damage to our business reputation and may adversely impact our ability to conduct our business.

The SEC has disclosure requirements for companies that use conflict minerals in their products. Some of these metals are commonly used in semiconductor devices, including our products. These SEC rules require companies to investigate, disclose and report whether or not such metals originated from the Democratic Republic of Congo or adjoining countries. We have numerous foreign suppliers, many of whom are not obligated by law to investigate their own supply chains. As a result, we may incur significant costs to comply with the diligence and disclosure requirements, including costs related to determining the source of any of the relevant metals used in our products. In addition, because our supply chain is with third parties, we may not be able to sufficiently verify the origin of all the relevant metals used in our products through the due diligence procedures we implement. We may also face difficulties in satisfying our customers if they require that we prove or certify that our products are “conflict free.” Key components and parts that can be shown to be “conflict free” may not be available to us in sufficient quantity, or at all,

11

or may only be available at significantly higher cost to us. If we are not able to meet customer requirements, customers may discontinue purchasing from us. Any of these outcomes could adversely impact our business, financial condition or operating results.

Risks Related to Our Organizational Structure

We are a holding company and our only material asset is our interest in ADK LLC, and we are accordingly dependent upon distributions made by our subsidiaries to pay taxes, make payments under the Tax Receivable Agreement and pay dividends.

We are a holding company with no material assets other than our ownership of LLC Units and our managing member interest in ADK LLC. As a result, we will have no independent means of generating revenue or cash flow. Our ability to pay taxes, make payments under the Tax Receivable Agreement and pay dividends will depend on the financial results and cash flows of ADK LLC and its subsidiaries and the distributions we receive from ADK LLC. Deterioration in the financial condition, earnings or cash flow of ADK LLC and its subsidiaries for any reason could limit or impair ADK LLC’s ability to pay such distributions. Additionally, to the extent that we need funds and ADK LLC and/or any of its subsidiaries are restricted from making such distributions under applicable law or regulation or under the terms of any financing arrangements, or ADK LLC is otherwise unable to provide such funds, it could materially adversely affect our liquidity and financial condition.

ADK LLC will continue to be treated as a partnership for U.S. federal income tax purposes and, as such, generally will not be subject to any entity-level U.S. federal income tax. Instead, taxable income will be allocated to holders of LLC Units. Accordingly, we will be required to pay income taxes on our allocable share of any net taxable income of ADK LLC. Under the terms of the Amended Operating Agreement, ADK LLC is obligated to make tax distributions to holders of LLC Units (including us) calculated at certain assumed tax rates. In addition to tax expenses, we will also incur expenses related to our operations, including payment obligations under the Tax Receivable Agreement (and the cost of administering such payment obligations), which could be significant. See the section entitled “Certain Relationships and Related Person Transactions — Tax Receivable Agreement.” We intend to cause ADK LLC to make distributions to holders of LLC Units in amounts sufficient to cover all applicable taxes (calculated at assumed tax rates), relevant operating expenses, payments under the Tax Receivable Agreement and dividends, if any, declared by us. However, as discussed below, ADK LLC’s ability to make such distributions may be subject to various limitations and restrictions including, but not limited to, restrictions on distributions that would either violate any contract or agreement to which ADK LLC is then a party, including debt agreements, or any applicable law, or that would have the effect of rendering ADK LLC insolvent. If our cash resources are insufficient to meet our obligations under the Tax Receivable Agreement and to fund our obligations, we may be required to incur additional indebtedness to provide the liquidity needed to make such payments, which could materially adversely affect our liquidity and financial condition and subject us to various restrictions imposed by any such lenders. To the extent that we are unable to make payments under the Tax Receivable Agreement for any reason, such payments will be deferred and will accrue interest until paid; provided, however, that nonpayment for a specified period may constitute a material breach of a material obligation under the Tax Receivable Agreement and therefore accelerate payments due under the Tax Receivable Agreement.

Additionally, although ADK LLC generally will not be subject to any entity-level U.S. federal income tax, it may be liable under recent federal tax legislation for adjustments to its tax return, absent an election to the contrary. In the event ADK LLC’s calculations of taxable income are incorrect, its members, including us, in later years may be subject to material liabilities pursuant to this federal legislation and its related guidance.

We anticipate that the distributions we will receive from ADK LLC may, in certain periods, exceed our actual tax liabilities and obligations to make payments under the Tax Receivable Agreement. Our board of directors, in its sole discretion, will make any determination from time to time with respect to the use of any such excess cash so accumulated, which may include, among other uses, to acquire additional newly issued LLC Units from ADK LLC at a per unit price determined by reference to the market value of the Class A common stock; to pay dividends, which may include special dividends, on our Class A common stock; to fund repurchases of Class A common stock; or any combination of the foregoing. We will have no obligation to distribute such cash (or other available cash other than any declared dividend) to our stockholders. To the extent that we do not distribute such excess cash as dividends on Class A common stock or otherwise undertake ameliorative actions between LLC Units and shares of Class A common stock and instead, for example, hold such cash balances, holders of LLC Units that held interests in ADK LLC pre-Business Combination may benefit from any value attributable to such cash balances as a result of their ownership of Class A

12

common stock following an exchange of their LLC Units, notwithstanding that such holders may previously have participated as holders of LLC Units in distributions by ADK LLC that resulted in such excess cash balances held by us. See the section entitled “Certain Relationships and Related Person Transactions — Amended Operating Agreement.”

Dividends on our common stock, if any, will be paid at the discretion of our board of directors, which will consider, among other things, our business, operating results, financial condition, current and expected cash needs, plans for expansion and any legal or contractual limitations on our ability to pay such dividends. Financing arrangements may include restrictive covenants that restrict our ability to pay dividends or make other distributions to our stockholders. In addition, ADK LLC is generally prohibited under state law from making a distribution to a member to the extent that, at the time of the distribution, after giving effect to the distribution, liabilities of ADK LLC (with certain exceptions) exceed the fair value of its assets. ADK LLC’s subsidiaries are generally subject to similar legal limitations on their ability to make distributions to ADK LLC. If ADK LLC does not have sufficient funds to make distributions, our ability to declare and pay cash dividends may also be restricted or impaired.

Under the Tax Receivable Agreement, we will be required to pay 85% of the tax benefits relating to tax depreciation or amortization deductions as a result of the tax basis step-up we receive in connection with the exchanges of LLC Units into our Class A common stock and related transactions, and those payments may be substantial.

Certain indie Equity Holders may exchange their LLC Units for shares of Class A common stock pursuant to the Exchange Agreement, subject to certain conditions and transfer restrictions as set forth therein and in the Amended Operating Agreement. These exchanges are expected to result in increases in our allocable share of the tax basis of the tangible and intangible assets of ADK LLC. These increases in tax basis may increase (for tax purposes) depreciation and amortization deductions and therefore reduce the amount of income or franchise tax that we would otherwise be required to pay in the future had such exchanges never occurred.

In connection with the Business Combination, we entered into the Tax Receivable Agreement, which generally provides for the payment by us of 85% of certain tax benefits, if any, that we realize (or in certain cases are deemed to realize) as a result of these increases in tax basis and certain tax attributes of the ADK Blocker Group and tax benefits related to entering into the Tax Receivable Agreement, including tax benefits attributable to payments under the Tax Receivable Agreement. These payments are the obligations of us and not of ADK LLC. The actual increase in our allocable share of ADK LLC’s tax basis in its assets, as well as the amount and timing of any payments under the Tax Receivable Agreement, will vary depending upon a number of factors, including the timing of exchanges, the market price of the Class A common stock at the time of the exchange, the extent to which such exchanges are taxable and the amount and timing of the recognition of our income. While many of the factors that will determine the amount of payments that we will make under the Tax Receivable Agreement are outside of our control, we expect that the payments we will make under the Tax Receivable Agreement will be substantial and could have a material adverse effect on our financial condition. Any payments made by us under the Tax Receivable Agreement will generally reduce the amount of overall cash flow that might have otherwise been available to us. To the extent that we are unable to make timely payments under the Tax Receivable Agreement for any reason, the unpaid amounts will be deferred and will accrue interest until paid. Furthermore, our future obligation to make payments under the Tax Receivable Agreement could make us a less attractive target for an acquisition, particularly in the case of an acquirer that cannot use some or all of the tax benefits that may be deemed realized under the Tax Receivable Agreement. See the section entitled “Certain Relationships and Related Person Transactions — Tax Receivable Agreement.”

In certain cases, payments under the Tax Receivable Agreement may exceed the actual tax benefits we realize or may be accelerated.

Payments under the Tax Receivable Agreement will be based on the tax reporting positions that we determine, and the Internal Revenue Service (the “IRS”) or another taxing authority may challenge all or any part of the tax basis increases, as well as other tax positions that we take, and a court may sustain such a challenge. In the event any tax benefits initially claimed by us are disallowed, the indie Equity Holders will not be required to reimburse us for any excess payments that may previously have been made under the Tax Receivable Agreement, for example, due to adjustments resulting from examinations by taxing authorities. Rather, excess payments made to such holders will be netted against any future cash payments otherwise required to be made by us, if any, after the determination of such excess. However, a challenge to any tax benefits initially claimed by us may not arise for a number of years following the initial time of such payment or, even if challenged early, such excess cash payment may be greater than the amount of future cash payments that we might otherwise be required to make under the terms of the Tax

13

Receivable Agreement and, as a result, there might not be future cash payments from which to net against. As a result, in certain circumstances we could make payments under the Tax Receivable Agreement in excess of our actual income or franchise tax savings, which could materially impair our financial condition.

Moreover, the Tax Receivable Agreement provides that, in the event that (i) we exercise our early termination rights under the Tax Receivable Agreement, (ii) we become bankrupt or undergo a similar insolvency event, (iii) certain changes of control occur (as described in the Tax Receivable Agreement) or (iv) we are more than three months late in making of a payment due under the Tax Receivable Agreement (unless we in good faith determine that hawse have insufficient funds to make such payment), our obligations under the Tax Receivable Agreement will accelerate and we will be required to make an immediate lump-sum cash payment to the indie Equity Holders equal to the present value of all forecasted future payments that would have otherwise been made under the Tax Receivable Agreement, which lump-sum payment would be based on certain assumptions, including those relating to our future taxable income. The lump-sum payment to the indie Equity Holders could be substantial and could exceed the actual tax benefits that we realize subsequent to such payment because such payment would be calculated assuming, among other things, that we would be able to use the assumed potential tax benefits in future years, and that tax rates applicable to us would be the same as they were in the year of the termination.

There may be a material negative effect on our liquidity if the payments under the Tax Receivable Agreement exceed the actual income or franchise tax savings that we realize. Furthermore, our obligations to make payments under the Tax Receivable Agreement could also have the effect of delaying, deferring or preventing certain mergers, asset sales, other forms of business combinations or other changes of control. We may need to incur additional indebtedness to finance payments under the Tax Receivable Agreement to the extent its cash resources are insufficient to meet our obligations under the Tax Receivable Agreement as a result of timing discrepancies or otherwise. Such indebtedness may have a material adverse effect on our financial condition.

Risks Related to Macroeconomic Conditions

Downturns or volatility in general economic conditions could have a material adverse effect on our business, financial condition, results of operations and liquidity.

Our net sales and profitability depend significantly on general economic conditions and the demand for the end products in the markets in which our customers compete. Weaknesses in the global economy and financial markets, including the current weaknesses resulting from the ongoing COVID-19 pandemic, have led to lower automotive demand. A decline in end-user demand can affect the need that customers have for our products, as well as the ability of customers to obtain credit or meet their payment obligations to us, and may increase the likelihood of customers canceling or deferring existing orders. Any further adverse changes in economic conditions, including any recession, economic slowdown or disruption of credit markets, may also lead to lower demand for our products. Volatile and uncertain economic conditions can make it difficult to accurately forecast and plan future business activities. This could result in an oversupply of products relative to customer demand.

In addition, any disruption in the credit markets, including as a result of the current COVID-19 pandemic, could impede our access to additional capital. If there is limited access to additional financing sources, we may be required to defer capital expenditures or seek other sources of liquidity, which may not be available on acceptable terms or at all. Similarly, if our suppliers face challenges in obtaining credit or other financial difficulties, they may be unable to provide the necessary materials or services to us.

All of these factors related to global economic conditions, which are beyond our control, could adversely impact our business, financial condition, results of operations and liquidity.

Fluctuations in foreign exchange rates could have an adverse effect on our results of operations.

We operate in various worldwide locations and our consolidated financial results are reported in U.S. dollars. However, some of the revenue and expenses of our foreign subsidiaries are denominated in local currencies. Fluctuations in foreign exchange rates against the U.S. dollar could result in changes in reported revenues and operating results due to the foreign exchange impact of translating these transactions into U.S. dollars. Currency fluctuations could decrease revenue and increase our operating costs. Though we have exposure to fluctuations in currency exchange rates, historically, the impact has generally not been material to our consolidated results of operations or financial position.

14

Our worldwide operations are subject to political, economic and health risks and natural disasters, which could have a material adverse effect on our business operations.

Our offices in California, the production facilities of third-party wafer suppliers, integrated circuit testing and manufacturing facilities, a portion of our assembly and research and development activities, and certain other critical business operations are located in or near seismically active regions and are subject to periodic earthquakes. We do not maintain earthquake insurance and could be materially and adversely affected in the event of a major earthquake.

Much of our revenue, as well as our manufacturers and assemblers, are concentrated in Asia, particularly in China. Such concentration increases the risk that natural disasters, labor strikes, terrorism, war, intensified political unrest, epidemics, and/or health advisories could damage, destroy or disrupt our suppliers or contract manufacturing facilities, disrupt operations, delay new production and shipments of existing products or result in costly repairs, replacements or other costs, all of which would negatively impact our business. A large natural disaster may result in disruptions in distribution channels or supply chains and significant increases in the prices of raw materials used for manufacturing processes. Furthermore, any disaster affecting our customers (or their respective customers) may significantly negatively impact the demand for our products and therefore our revenue. There is increasing concern that climate change is occurring that may cause a rising number of natural disasters with potentially dramatic effects on human activity.

The COVID-19 outbreak first identified in China in December 2019 has resulted in significant disruptions in business operations and other economic activities in many parts of the country. The World Health Organization has declared the growing disease to be a global health emergency, and the U.S. government has issued travel restrictions to and from China. Any prolonged health threat from COVID-19 globally could have a material adverse impact on our business operations and results of operations.

In addition, we rely heavily on internal information and communications systems and on systems or support services from third parties to manage our operations efficiently and effectively. Any of these are subject to failure due to a natural disaster or other disruptions. System-wide or local failures that affect our information processing could have material adverse effects on our business, financial condition, results of operations and cash flows.

Risks Related to our Intellectual Property, Technology and Cybersecurity.

We rely to a significant extent on proprietary intellectual property. We may not be able to protect this intellectual property against improper use by our competitors or others.

Our success and future revenue growth depend, in part, on our ability to protect our proprietary technology, products, designs and fabrication processes, and other intellectual property, against misappropriation by others. We primarily rely on patent, copyright, trademark and trade secret laws, as well as nondisclosure agreements and other methods, to protect our intellectual property. We may have difficulty obtaining patents and other intellectual property rights to protect our proprietary products, technology and intellectual property, and the patents and other intellectual property rights received may be insufficient to provide us with meaningful protection or commercial advantage. We may not obtain patent protection or secure other intellectual property rights in all the countries in which we operate, and under the laws of such countries, patents and other intellectual property rights may be or become unavailable or limited in scope. Even if new patents are issued, the claims allowed may not be sufficiently broad to effectively protect proprietary technology, processes and other intellectual property. In addition, any of our existing patents, and any future patents issued, may be challenged, invalidated or circumvented.

Further, proprietary technology, designs and processes and other intellectual property may be vulnerable to disclosure or misappropriation by employees, contractors and other persons. It is possible that competitors or other unauthorized third parties may obtain, copy, use or disclose our proprietary technologies, products, designs, processes and other intellectual property despite efforts to protect intellectual property. While we have a number of patent filings in process, there can be no assurances that these patents will be issued or that any rights will be granted and provide meaningful protection against misappropriation of intellectual property. Competitors may also be able to develop similar technology independently or design around our patents. We may not have or pursue patents or pending applications in all the countries in which we operate corresponding to all primary patents and applications. Even if patents are granted, effective enforcement in some countries may not be available. In particular, intellectual property rights are difficult to enforce in countries where the application and enforcement of the laws governing such rights may not have reached the same level as compared to other jurisdictions where we operate. Consequently, operating

15

in some countries may subject us to an increased risk that unauthorized parties may attempt to copy or otherwise use intellectual property or the intellectual property of suppliers or other parties with whom we engage. There is no assurance that we will be able to protect our intellectual property rights or have adequate legal recourse in the event that we seek legal or judicial enforcement of our intellectual property rights under the laws of such countries. Any inability on our part to adequately protect our intellectual property may have a material adverse effect on our business, financial condition and results of operations.

We may become party to intellectual property claims or litigation that could cause us to incur substantial costs, pay substantial damages or prohibit us from selling our products.

The semiconductor industry is characterized by frequent litigation regarding patent and other intellectual property rights. From time to time, we may receive communications from third parties that allege that our products or technologies infringe their patent or other intellectual property rights. Lawsuits or other proceedings resulting from allegations of infringement could subject us to significant liability for damages, invalidate our proprietary rights and adversely affect our business. In the event that any third-party succeeds in asserting a valid claim against us or any of our customers, we could be forced to do one or more of the following:

•        discontinue selling, importing or using certain technologies that contain the allegedly infringing intellectual property which could cause us to stop manufacturing certain products;

•        seek to develop non-infringing technologies, which may not be feasible;

•        incur significant legal expenses;

•        pay substantial monetary damages to the party whose intellectual property rights we may be found to be infringing; and/or

•        we or our customers could be required to seek licenses to the infringed technology that may not be available on commercially reasonable terms, if at all.

If a third-party causes us to discontinue the use of any technologies, we could be required to design around those technologies. This could be costly and time consuming and could have an adverse effect on our financial results. Any significant impairments of intellectual property rights from any litigation we face could materially and adversely impact our business, financial condition, results of operations and our ability to compete.

Certain software that we use in our products is licensed from third parties and may not be available to us in the future, which may delay product development and production or cause us to incur additional expense.

Some of our solutions contain software licensed from third parties, some of which may not be available to us in the future on terms that are acceptable to us or allow our products to remain competitive. The loss of these licenses or the inability to maintain any of them on commercially acceptable terms could delay development of future products or the enhancement of existing products.

Interruptions in information technology systems could adversely affect business.

We rely on the efficient and uninterrupted operation of complex information technology applications, systems and networks to operate our business. The reliability and security of information technology infrastructure and software, and our ability to expand and continually update technologies in response to changing needs is critical to our business. Any significant interruption in these applications, systems or networks, including but not limited to new system implementations, computer viruses, cyberattacks, security breaches, facility issues or energy blackouts, could have a material adverse impact on our business, financial condition and results of operations.

Our business also depends on various outsourced IT services. We rely on third-party vendors to provide critical services and to adequately address cyber security threats to their own systems. Any failure of third-party systems and services to operate effectively could disrupt our operations and could have a material adverse effect on our business, financial condition and results of operations.

16

Our computer systems and networks are subject to attempted security breaches and other cybersecurity incidents, which, if successful, could be costly and could impact our business.

Cyber-attacks attempting to obtain access to our computer systems and networks could result in the misappropriation of proprietary information and technology. There can be no assurance that any breach or incident will not have a material impact on our operations and financial results. In the current environment, there are numerous and evolving risks to cybersecurity and privacy, including criminal hackers, state-sponsored intrusions, industrial espionage, employee malfeasance, and human or technological error. In the event of such breaches, us, our customers or other third parties could be exposed to potential liability, litigation, and regulatory action, as well as the loss of existing or potential customers, damage to reputation, and other financial loss.

In addition, the cost and operational consequences of responding to breaches and implementing remediation measures could be significant. We could also be impacted by existing and proposed laws and regulations, as well as government policies and practices related to cybersecurity, privacy and data protection.

Cyber-attacks or other catastrophic events could result in interruptions or delays to us, our customers, or other third party operations or services, financial loss, potential liability, and damage to our reputation and affect our relationships with customers and suppliers.

Further, we may be subject to theft, loss, or misuse of personal and confidential data regarding our employees, customers and suppliers that is routinely collected, used, stored, and transferred to run our business. Such theft, loss, or misuse could result in significantly increased business and security costs or costs related to defending legal claims.

Global privacy legislation, enforcement, and policy activity in this area are rapidly expanding and creating a complex regulatory compliance environment. In addition, even inadvertent failure to comply with federal, state, or international privacy-related or data protection laws and regulations could result in proceedings against us by governmental entities or others.

Our costs to comply with and implement these privacy-related and data protection measures could be significant.

Risks Related to Regulatory Compliance and Legal Matters

Our failure to comply with the large body of laws and regulations to which we are subject could have a material adverse effect on our business and operations.

We are subject to regulation by various governmental agencies in the United States and other jurisdictions in which we operate. These include traditional automotive quality standards/regulations as well as international trade regulations. Our failure to comply with any applicable regulations or requirements could subject us to investigations, sanctions, enforcement actions, fines, damages, penalties, or injunctions. If any governmental sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, financial condition and results of operations could be materially and adversely affected. In addition, responding to any action will likely result in a significant diversion of management’s attention and financial resources.

Our business may be adversely affected by costs relating to product defects, and we could be faced with product liability claims.

There is a risk that defects may occur in our products. We make highly complex integrated circuits and our customers typically integrate the semiconductors we sell into numerous automotive products, which are then sold into the marketplace. A defect in any of our products could give rise to significant costs, including expenses relating to recalling the products, replacing defective items and writing down defective inventory as well as lead to the loss of potential sales.

In addition, the occurrence of such defects may give rise to product liability claims, including liability for damages caused by such defects if our semiconductors or the consumer products based on them malfunction and result in personal injury or death. Such claims could result in significant costs and expenses relating to damages and attorneys’ fees. Moreover, since the cost of replacing defective semiconductor devices is often much higher than the value of the devices themselves, we may at times face damage claims from customers that are in excess of the amounts paid to us for products, including consequential damages. We may be even named in product liability claims where there is no evidence that our products caused the damage in question.

17

Additionally, customers may recall their end products if they prove to be defective or they may make compensatory payments in accordance with industry or business practice or in order to maintain good customer relationships. If such a recall or payment is caused by a defect in one of our products, customers may seek to recover all or a portion of their losses from us. If any of these risks materialize, our reputation would be harmed and there could be a material adverse effect on our business, financial condition and results of operations.

We may face significant warranty claims.

Our semiconductor devices are sold with warranties. The warranty for our products requires us to repair or replace products that are deficient. As a result, we bear the risk of warranty claims on all products we supply, including those manufactured by third parties. There can be no assurance that we will be successful in claiming under any warranty or indemnity provided to us by our suppliers or vendors in the event of a successful warranty claim against us by a customer, or that any recovery from such vendor or supplier would be adequate. There is a risk that warranty claims made against us will exceed our warranty reserve and could have a material adverse effect on our financial condition, results of operations, business and/or prospects.

Significant litigation could impair our reputation and cause us to incur substantial costs.

We may be party to various lawsuits and claims arising in the ordinary course of business, including claims relating to intellectual property, customer contracts, employment matters, third-party manufacturers or subcontractors, or other aspects of our business. Litigation, regardless of outcome, could result in substantial costs, reputational harm and a diversion of management’s attention and resources. The outcome of litigation is often difficult to predict, and any litigation may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our business and operations could be negatively affected if it becomes subject to any securities litigation or stockholder activism, which could cause us to incur significant expense, hinder execution of business and growth strategy and impact our stock price.

In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been brought against that company. Stockholder activism, which could take many forms or arise in a variety of situations, has been increasing recently. Volatility in the stock price of our Class A common stock, allegations arising in connection with the Business Combination or other reasons may in the future cause it to become the target of securities litigation or stockholder activism. Securities litigation and stockholder activism, including potential proxy contests, could result in substantial costs and divert management’s and our board of directors’ attention and resources from our business. Additionally, such securities litigation and stockholder activism could give rise to perceived uncertainties as to our future, adversely affect our relationships with service providers and make it more difficult to attract and retain qualified personnel. Also, we may be required to incur significant legal fees and other expenses related to any securities litigation and activist stockholder matters. Further, our stock price could be subject to significant fluctuation or otherwise be adversely affected by the events, risks and uncertainties of any securities litigation and stockholder activism.

We are subject to export restrictions and laws affecting trade and investments that could materially and adversely affect our business and results of operations.

We have material operations and relationships in China, including an interest in a Chinese subsidiary. Since the beginning of 2018, there have been several instances of U.S. tariffs on Chinese goods, some of which prompted retaliatory Chinese tariffs on U.S. goods. In May 2019, the U.S. president issued an executive order that invoked national emergency economic powers to implement a framework to regulate the acquisition or transfer of information communications technology in transactions that imposed undue national security risks. These actions could lead to additional restrictions on the export of products that include or enable certain technologies, including products we provide to China-based customers.

The institution of trade tariffs both globally and between the U.S. and China specifically carries the risk of negatively affecting China’s overall economic condition, which could have a negative impact on us as we have significant operations in China.

18

Furthermore, the imposition of tariffs could cause a decrease in the sales of products to customers located in China or other customers selling to Chinese end users, which could materially and adversely affect our business, financial condition and results of operations.

We are subject to U.S. laws and regulations that could limit and restrict the export of some products and services and may restrict transactions with certain customers, business partners and other persons, including, in certain cases, dealings with or between our employees and subsidiaries. In certain circumstances, export control and economic sanctions regulations may prohibit the export of certain products, services and technologies and in other circumstances we may be required to obtain an export license before exporting the controlled item. Compliance with these laws and regulations could materially limit operations or sales, which would materially and adversely affect our business and results of operations.

In addition, U.S. laws and regulations and sanctions, or threat of sanctions, that could limit and restrict the export of some of our products and services to customers, may also encourage customers to develop their own solutions to replace our products, or seek to obtain a greater supply of similar or substitute products from competitors that are not subject to these restrictions, which could materially and adversely affect our business, financial condition and results of operations.

We could be subject to domestic or international changes in tax rates or the adoption of new tax legislation, or we could otherwise have exposure to additional tax liabilities, which could adversely affect our results of operations or financial condition.

We are subject to income and other taxes in both the United States and various foreign jurisdictions. Changes to sustained yield or regulations in the jurisdictions in which we operate, or in the interpretation of such laws or regulations, could significantly increase our effective tax rate and reduce cash flow from operating activities, and otherwise have a material adverse effect on our financial condition. In addition, other factors or events, including business combinations and investment transactions, changes in the valuation of deferred tax assets and liabilities, adjustments to taxes upon finalization of various tax returns or as a result of deficiencies asserted by taxing authorities, increases in expenses not deductible for tax purposes, changes in available tax credits, changes in transfer pricing methodologies, other changes in the apportionment of income and other activities among tax jurisdictions, and changes in tax rates, could also increase our effective tax rate.

Our tax filings are subject to review or audit by the U.S. Internal Revenue Service (the “IRS”) and state, local and foreign taxing authorities. We exercise significant judgment in determining our worldwide provision for taxes and, in the ordinary course of business, there may be transactions and calculations where the proper tax treatment is uncertain. Our determinations are not binding on the IRS or any other taxing authorities, and accordingly the final determination in an audit or other proceeding may be materially different than the treatment reflected in our tax provisions, accruals and returns. An assessment of additional taxes because of an audit could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We could be adversely affected by violations of applicable anti-corruption laws or violations of our internal policies designed to ensure ethical business practices.

We operate in a number of countries throughout the world, including in countries that do not have as strong a commitment to anti-corruption and ethical behavior as is required by U.S. laws or by corporate policies. We are subject to the risk that us, our U.S. employees or our employees located in other jurisdictions or any third parties that we engage to do work on our behalf in foreign countries may take action determined to be in violation of anti-corruption laws in any jurisdiction in which we conduct business, including the U.S. Foreign Corrupt Practices Act of 1977 (the “FCPA”). In addition, we operate in certain countries in which the government may take an ownership stake in an enterprise and such government ownership may not be readily apparent (thereby increasing potential FCPA violations). Any violation of the FCPA or any similar anti-corruption law or regulation could result in substantial fines, sanctions, civil and/or criminal penalties and curtailment of operations in certain jurisdictions and might adversely affect our business, results of operations or financial condition. In addition, we have internal ethics policies that we require our employees to comply with in order to ensure that our business is conducted in a manner that our management deems appropriate. If these anti-corruption laws or internal policies were to be violated, our reputation and operations could also be substantially harmed.

19

In order to comply with environmental and occupational health and safety laws and regulations, we may need to modify our activities or incur substantial costs, and such laws and regulations, including any failure to comply with such laws and regulations, could subject us to substantial costs, liabilities, obligations and fines, or require us to have suppliers alter their processes.

The semiconductor industry is subject to a variety of international, federal, state, local and non-U.S. laws and regulations governing pollution, environmental protection and occupational health and safety. Compliance with current or future environmental and occupational health and safety laws and regulations could restrict our ability to expand our business or require us to modify processes or incur other substantial expenses which could harm business. Environmental and occupational health and safety laws and regulations have tended to become more stringent over time, causing a need to redesign technologies, imposing greater compliance costs and increasing risks and penalties associated with violations, which could seriously harm business.

Risks Related to Financial Reporting, Internal Controls and Being a Public Company

The unaudited pro forma financial information included in the section entitled “Unaudited Pro Forma Condensed Combined Financial Information” may not be representative of our results after the Business Combination.

Prior to the Business Combination, Thunder Bridge II and ADK LLC operated as separate companies and had no prior history as a combined entity, and our operations and those of ADK LLC have not previously been managed on a combined basis. The pro forma financial information included in this prospectus is presented for informational purposes only and is not necessarily indicative of the financial position or results of operations that would have actually occurred had the Business Combination been completed at or as of the dates indicated, nor is it indicative of our future operating results or financial position. The pro forma statement of operations does not reflect future nonrecurring charges resulting from the Business Combination. The unaudited pro forma financial information does not reflect future events that may occur after the Business Combination and does not consider potential impacts of future market conditions on revenues or expenses. The pro forma financial information included in the section entitled “Unaudited Pro Forma Condensed Combined Financial Information” has been derived from Thunder Bridge II’s and ADK LLC’s historical financial statements and certain adjustments and assumptions have been made regarding us after giving effect to the Business Combination. There may be differences between preliminary estimates in the pro forma financial information and the final acquisition accounting, which could result in material differences from the pro forma information presented in this prospectus in respect of our estimated financial position and results of operations.

In addition, the assumptions used in preparing the pro forma financial information may not prove to be accurate and other factors may affect our financial condition or results of operations. Any potential decline in our financial condition or results of operations may cause significant variations in our stock price.

Inadequate internal controls could result in inaccurate financial reporting.

If we fail to maintain an effective system of internal controls, we may not be able to accurately report our financial results. As a result, our stakeholders could lose confidence in our financial reporting, which could adversely affect the results of our business and our enterprise value.

We will need to undertake significant efforts to strengthen our processes and systems and adapt them to changes as our business evolves (including with respect to becoming a publicly traded company). This continuous process of maintaining and adapting our internal controls is expensive and time-consuming, and requires significant management attention. We cannot be certain that our internal control measures will, in the future, provide adequate control over our financial processes and reporting. Furthermore, as our business evolves, and if we expand through acquisitions of other companies, make significant investments in other companies or enter into joint development and similar arrangements, our internal controls may become more complex and we will require significantly more resources to ensure our internal controls remain effective. Failure to implement required new or improved controls, or difficulties encountered in their implementation, could harm our operating results or cause us to fail to meet our reporting obligations. If we or our independent registered public accounting firm identify material weaknesses, the disclosure of that fact, even if quickly remediated, could reduce the market’s confidence in our financial statements and harm our enterprise value.

20

We may not be able to timely and effectively implement and maintain controls and procedures required by Section 404 of the Sarbanes-Oxley Act that are applicable to us.

As a public company, we are required to comply with the SEC’s rules implementing Sections 302 and 404 of the Sarbanes-Oxley Act, which require management to certify financial and other information in our quarterly and annual reports and provide an annual management report on the effectiveness of internal control over financial reporting. To comply with the requirements of being a public company, we will be required to provide attestation on internal controls, and we may need to undertake various actions, such as implementing additional internal controls and procedures and hiring additional accounting or internal audit staff. The standards required for a public company under Section 404 of the Sarbanes-Oxley Act are significantly more stringent than those required of us as a privately held company. Management may not be able to effectively implement and maintain controls and procedures that adequately respond to the increased regulatory compliance and reporting requirements that are applicable to us. If we are not able to satisfy the additional requirements of Section 404 in a timely manner or with adequate compliance, we may not be able to assess whether our internal controls over financial reporting are effective, which may subject us to adverse regulatory consequences and could harm investor confidence and the market price of our securities. Further, as an emerging growth company, our independent registered public accounting firm is not required to formally attest to the effectiveness of our internal controls over financial reporting pursuant to Section 404 until the date we are no longer an emerging growth company. At such time, our independent registered public accounting firm may issue a report that is adverse in the event that it is not satisfied with the level at which our controls are documented, designed or operating.

We will incur significant increased expenses and administrative burdens as a public company, which could have a material adverse effect on our business, financial condition and results of operations.

We face increased legal, accounting, administrative and other costs and expenses as a public company that we have not incurred as a private company. The Sarbanes-Oxley Act, including the requirements of Section 404, as well as rules and regulations subsequently implemented by the SEC, the Dodd-Frank Act and the rules and regulations promulgated and to be promulgated thereunder, the Public Company Accounting Oversight Board and the securities exchanges, impose additional reporting and other obligations on public companies. Compliance with public company requirements increases costs and makes certain activities more time-consuming. A number of those requirements require us to carry out activities we did not do previously. For example, we created new board committees and adopted new internal controls and disclosure controls and procedures. In addition, additional expenses associated with SEC reporting requirements will be incurred. Furthermore, if any issues in complying with those requirements are identified (for example, if the auditors identify a material weakness or significant deficiency in our internal control over financial reporting), we could incur additional costs rectifying those issues, and the existence of those issues could adversely affect our reputation or investor perceptions of it. It may also be more expensive to obtain director and officer liability insurance. Risks associated with our status as a public company may make it more difficult to attract and retain qualified persons to serve on the board of directors or as executive officers. The additional reporting and other obligations imposed by these rules and regulations will increase legal and financial compliance costs and the costs of related legal, accounting and administrative activities. These increased costs will require us to divert a significant amount of money that could otherwise be used to expand the business and achieve strategic objectives. Advocacy efforts by stockholders and third parties may also prompt additional changes in governance and reporting requirements, which could further increase costs.

We qualify as an “emerging growth company” within the meaning of the Securities Act, and if we take advantage of certain exemptions from disclosure requirements available to emerging growth companies, we could make our securities less attractive to investors and may make it more difficult to compare our performance to the performance of other public companies.

We qualify as an “emerging growth company” as defined in Section 2(a)(19) of the Securities Act, as modified by the JOBS Act. As such, we are eligible for and intend to take advantage of certain exemptions from various reporting requirements applicable to other public companies that are not emerging growth companies for as long as we continue to be an emerging growth company, including (a) the exemption from the auditor attestation requirements with respect to internal control over financial reporting under Section 404(b) of the Sarbanes-Oxley Act, (b) the exemptions from say-on-pay, say-on-frequency and say-on-golden parachute voting requirements and (c) reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. We will remain an emerging growth company until the earliest of (i) the last day of the fiscal year in which the market value of common stock that is held by non-affiliates exceeds $700.0million as of June 30 of that fiscal year, (ii) the last day of

21

the fiscal year in which we have total annual gross revenue of $1.07billion or more during such fiscal year (as indexed for inflation), (iii) the date on which we have issued more than $1billion in non-convertible debt in the prior three-year period or (iv) December31, 2024. In addition, Section 107 of the JOBS Act also provides that an emerging growth company can take advantage of the exemption from complying with new or revised accounting standards provided in Section 7(a)(2)(B) of the Securities Act as long as it is an emerging growth company. An emerging growth company can therefore delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected not to opt out of such extended transition period and, therefore, we may not be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies. Investors may find our securities less attractive because we will rely on these exemptions, which may result in a less active trading market for our securities.

Our actual operating results may differ significantly from our guidance.

From time to time, we provide forward-looking estimates regarding our future performance that represent our management’s estimates as of a point in time. These forward-looking statements are based on projections prepared by our management. These projections are not prepared with a view toward compliance with published guidelines of the American Institute of Certified Public Accountants, and neither our independent registered public accountants nor any other independent expert or outside party compiles or examines the projections and, accordingly, no such person expresses any opinion or any other form of assurance on our projections.

Projections are based upon a number of assumptions and estimates that, while presented with numerical specificity, are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond our control and are based upon specific assumptions with respect to future business decisions and conditions, some of which will change. The principal reason that we provide forward-looking information is to provide a basis for our management to discuss our business outlook with stakeholders. Forward-looking statements are necessarily speculative in nature, and it can be expected that some or all of the assumptions of our forward-looking statements will not materialize or will vary significantly from actual results. Accordingly, our forward-looking statements are only an estimate of what management believes is realizable as of the date of release. Actual results will vary from our forward-looking statements and the variations may be material. In light of the foregoing, investors are urged not to rely upon, or otherwise consider, our guidance in making investment decisions.

Risks Related to Ownership of Our Class A Common Stock and Warrants, and Organizational Documents

There can be no assurance we will be able to comply with the continued listing standards of Nasdaq for our Class A common stock.

Our Class A common stock and public warrants are currently listed on the Nasdaq Stock Market. In order to maintain such listing, we must satisfy minimum financial and other continued listing requirements and standards. If Nasdaq delists our Class A common stock from trading on its exchange for failure to meet the listing standards, we and our securityholders could face significant material adverse consequences including:

•        a limited availability of market quotations for our securities;

•        reduced liquidity for our securities;

•        a determination that shares of the Class A common stock are a “penny stock” which will require brokers trading in the Class A common stock to adhere to more stringent rules and possibly result in a reduced level of trading activity in the secondary trading market for our securities;

•        a limited amount of news and analyst coverage; and

•        a decreased ability to issue additional securities or obtain additional financing in the future.

We may redeem your unexpired warrants prior to their exercise at a time that is disadvantageous to you, thereby making your warrants worthless.

We have the ability to redeem outstanding warrants at any time after they become exercisable and prior to their expiration, at a price of $0.01 per warrant; provided that the last reported sales price of our Class A common stock equals or exceeds $18.00 per share (as adjusted for share splits, share dividends, reorganizations, recapitalizations and

22

the like) for any 20 trading days within a 30 trading-day period ending on the third trading day prior to the date we send the notice of such redemption to the warrant holders. If and when the warrants become redeemable by us, we may exercise our redemption right even if we are unable to register or qualify the underlying securities for sale under all applicable state securities laws. Redemption of the outstanding warrants could force you (i) to exercise your warrants and pay the exercise price therefor at a time when it may be disadvantageous for you to do so, (ii) to sell your warrants at the then-current market price when you might otherwise wish to hold your warrants or (iii) to accept the nominal redemption price which, at the time the outstanding warrants are called for redemption, is likely to be substantially less than the market value of your warrants.

Our warrants may have an adverse effect on the market price of our Class A common stock.

We have outstanding warrants to purchase up to 27,400,000shares of our Class A common stock. To the extent such warrants are exercised, additional shares of our Class A common stock will be issued, which will result in dilution to our stockholders and increase the number of shares of Class A common stock eligible for resale in the public market. Sales of substantial numbers of such shares in the public market or the fact that such warrants may be exercised could adversely affect the market price of our Class A common stock.

You may be diluted by the future issuance of additional Class A common stock or LLC Units in connection with our incentive plans, acquisitions or otherwise.

We have 250,000,000shares of Class A common stock authorized but unissued, including 34,476,883shares of Class A common stock issuable upon exchange of LLC Units that are held by certain indie Equity Holders and 27,400,000shares of Class A common stock issuable upon exercise of the warrants and 10,368,750shares of Class A common stock reserved for issuance under the Equity Incentive Plan as described below. Our Certificate of Incorporation authorizes us to issue these shares of Class A common stock and options, rights, warrants and appreciation rights relating to Class A common stock for the consideration and on the terms and conditions established by our board of directors in its sole discretion, whether in connection with acquisitions or otherwise. Similarly, the Amended Operating Agreement permits ADK LLC to issue an unlimited number of additional limited liability company interests of ADK LLC with designations, preferences, rights, powers and duties that are different from, and may be senior to, those applicable to the LLC Units, and which may be exchangeable for shares of Class A common stock. Additionally, we have reserved an aggregate of 10,368,750shares of Class A common stock and LLC Units for issuance under the Equity Incentive Plan. Any Class A common stock that we issue, including under the Equity Incentive Plan or other equity incentive plans that we may adopt in the future, would dilute the percentage ownership held by the investors who own shares of Class A common stock.

There may be sales of a substantial amount of Class A common stock by our stockholders and these sales could cause the price of our securities to fall.

Pursuant to the Registration Rights Agreement described in “Certain Relationships and Related Person Transactions — Registration Rights Agreement,” certain stockholders are entitled to demand that we register the resale of their securities subject to certain minimum requirements. This prospectus forms the part of a registration statement we have filed with the SEC to register the resale of securities held by certain of our stockholders, as further described herein. The stockholders who are parties to the Registration Rights Agreement also have certain “piggyback” registration rights with respect to registration statements filed subsequent to the Business Combination.

Upon effectiveness of any registration statement we file pursuant to the Registration Rights Agreement (including the registration statement of which prospectus is a party), and upon the expiration of the lockup periods applicable to the parties to the Registration Rights Agreement, these parties may sell large amounts of our Class A common stock in the open market or in privately negotiated transactions, which could have the effect of increasing the volatility in the share price of Class A common stock or putting significant downward pressure on the price of our Class A common stock.

Sales of substantial amounts of our Class A common stock in the public market, or the perception that such sales will occur, could adversely affect the market price of our Class A common stock and make it difficult for us to raise funds through securities offerings in the future.

23

Delaware law and our Certificate of Incorporation and Bylaws contain certain provisions, including anti-takeover provisions, that limit the ability of stockholders to take certain actions and could delay or discourage takeover attempts that stockholders may consider favorable.

Our Certificate of Incorporation and Bylaws, and the DGCL, contain provisions that could have the effect of rendering more difficult, delaying, or preventing an acquisition that stockholders may consider favorable, including transactions in which stockholders might otherwise receive a premium for their shares. These provisions could also limit the price that investors might be willing to pay in the future for shares of our common stock, and therefore depress the trading price of our Class A common stock. These provisions could also make it difficult for stockholders to take certain actions, including electing directors who are not nominated by the current members of our board of directors or taking other corporate actions, including effecting changes in management. Among other things, the Certificate of Incorporation and Bylaws include provisions regarding:

•        a classified board of directors with three-year staggered terms, which could delay the ability of stockholders to change the membership of a majority of our board of directors;

•        the ability of our board of directors to issue shares of preferred stock, including “blank check” preferred stock and to determine the price and other terms of those shares, including preferences and voting rights, without stockholder approval, which could be used to significantly dilute the ownership of a hostile acquirer;

•        the limitation of the liability of, and the indemnification of, our directors and officers;

•        the right of our board of directors to elect a director to fill a vacancy created by the expansion of our board of directors or the resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on our board of directors;

•        the requirement that directors may only be removed from our board of directors for cause;

•        the requirement that a special meeting of stockholders may be called only by our board of directors, the chairman of our board of directors or our chief executive officer, which could delay the ability of stockholders to force consideration of a proposal or to take action, including the removal of directors;

•        controlling the procedures for the conduct and scheduling of meetings of our board of directors and stockholders;

•        the requirement for the affirmative vote of holders of 66⅔% of the voting power of our outstanding voting capital stock, voting together as a single class to amend, alter, change or repeal certain provisions in the Certificate of Incorporation and the Bylaws, respectively, which could preclude stockholders from bringing matters before annual or special meetings of stockholders and delay changes in our board of directors and also may inhibit the ability of an acquirer to effect such amendments to facilitate an unsolicited takeover attempt;

•        the ability of our board of directors to amend the Bylaws, which may allow our board of directors to take additional actions to prevent an unsolicited takeover and inhibit the ability of an acquirer to amend the Bylaws to facilitate an unsolicited takeover attempt; and

•        advance notice procedures with which stockholders must comply to nominate candidates to our board of directors or to propose matters to be acted upon at a stockholders’ meeting, which could preclude stockholders from bringing matters before annual or special meetings of stockholders and delay changes in our board of directors and also may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of us.

These provisions, alone or together, could delay or prevent hostile takeovers and changes in control or changes in our board of directors or management.

24

In addition, as a Delaware corporation, we are generally subject to provisions of Delaware law, including the DGCL. Although we have elected not to be governed by Section 203 of the DGCL, certain provisions of the Certificate of Incorporation, in a manner substantially similar to Section 203 of the DGCL, prohibit certain stockholders (other than those stockholders who are party to a stockholders’ agreement with us) who hold 15% or more of our outstanding capital stock from engaging in certain business combination transactions with us for a specified period of time unless certain conditions are met. See the section entitled “Description of Securities — Anti-Takeover Effects of the Certificate of Incorporation, the Bylaws and Certain Provisions of Delaware Law.”

Any provision of the Certificate of Incorporation, Bylaws or Delaware law that has the effect of delaying or preventing a change in control could limit the opportunity for stockholders to receive a premium for their shares of our capital stock and could also affect the price that some investors are willing to pay for our common stock.

The form of the Certificate of Incorporation is attached as an exhibit to the registration statement of which the prospectus forms a part, and we urge you to read it.

Our Certificate of Incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or other employees.

Our Certificate of Incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by law, be the sole and exclusive forum for any (1) derivative action or proceeding brought on behalf of us, (2) action asserting a claim of breach of a fiduciary duty owed by any director, officer, employee or agent of ours to us or our stockholders, or any claim for aiding and abetting any such alleged breach, (3) action arising pursuant to any provision of the DGCL or our Certificate of Incorporation or our Bylaws or as to which the DGCL confers jurisdiction on the Court of Chancery, or (4) action asserting a claim against us. Our Certificate of Incorporation also provides that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States of America will be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. Notwithstanding the foregoing, the inclusion of such provision in our Certificate of Incorporation will not be deemed to be a waiver by our stockholders of our obligation to comply with federal securities laws, rules and regulations, and the provisions of this paragraph will not apply to suits brought to enforce any liability or duty created by the Exchange Act or any other claim for which the federal district courts of the United States of America shall be the sole and exclusive forum. Any person or entity purchasing or otherwise acquiring any interest in any shares of our capital stock shall be deemed to have notice of and to have consented to the forum provisions in our Certificate of Incorporation. If any action the subject matter of which is within the scope of the Delaware Exclusive Forum Provision is filed in a court other than a court located within the State of Delaware (a “foreign action”) in the name of any stockholder, such stockholder shall be deemed to have consented to: (x) the personal jurisdiction of the state and federal courts located within the State of Delaware in connection with any action brought in any such court to enforce the forum provisions (an “enforcement action”), and (y) having service of process made upon such stockholder in any such enforcement action by service upon such stockholder’s counsel in the foreign action as agent for such stockholder.

This choice-of-forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits. Alternatively, if a court were to find this provision of our Certificate of Incorporation inapplicable or unenforceable with respect to one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could materially and adversely affect our business, financial condition and results of operations and result in a diversion of the time and resources of our management and board of directors.

General Risk Factors

The market price of our securities may fluctuate or decline.

Fluctuations in the price of our securities could contribute to the loss of all or part of your investment. The trading price of our securities could be volatile and subject to wide fluctuations in response to various factors, some of which are beyond our control. Any of the factors listed below could have a material adverse effect on your investment in our securities and our securities may trade at prices significantly below the price you paid for them. In such circumstances, the trading price of our securities may not recover and may experience a further decline.

Factors affecting the trading price of our securities may include:

•        actual or anticipated fluctuations in our quarterly financial results or the quarterly financial results of companies perceived to be similar to us;

•        changes in the market’s expectations about our operating results;

•        success of competitors;

•        our operating results failing to meet the expectation of securities analysts or investors in a particular period;

•        changes in financial estimates and recommendations by securities analysts concerning us or our industry in general;

•        operating and share price performance of other companies that investors deem comparable to us;

•        our ability to market new and enhanced products on a timely basis;

•        changes in laws and regulations affecting our business;

•        our ability to meet compliance requirements;

•        commencement of, or involvement in, litigation involving us;

•        changes in our capital structure, such as future issuances of securities or the incurrence of additional debt;

•        the volume of shares of Class A common stock available for public sale;

•        any major change in our board of directors or management;

•        sales of substantial amounts of Class A common stock by our directors, executive officers or significant stockholders or the perception that such sales could occur; and

•        general economic and political conditions such as recessions, interest rates, international currency fluctuations and acts of war or terrorism.

Broad market and industry factors may materially harm the market price of our securities irrespective of our operating performance. The stock market in general has experienced price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of the particular companies affected. The trading prices and valuations of these stocks, and of our securities, may not be predictable. A loss of investor confidence in the market for retail stocks or the stocks of other companies which investors perceive to be similar to us could depress our stock price regardless of our business, prospects, financial condition or results of operations. A decline in the market price of our securities also could adversely affect our ability to issue additional securities and our ability to obtain additional financing in the future.

26

Loss of key management or other highly skilled personnel, or an inability to attract such management and other personnel, could adversely affect our business.

We depend on key management to run our business and on development engineers to develop new products and technologies. The loss of any key personnel could have a material adverse effect on our business. In addition, the market for qualified employees, including skilled engineers and other individuals with the required technical expertise to succeed in our business, is highly competitive and an inability to attract, retain and motivate the employees required for the operation of our business could hinder our ability to successfully conduct research activities or develop marketable products.

Generally, our employees are not bound by obligations that require them to continue to work for any specified period and, therefore, they could terminate their employment at any time. Moreover, our employees are generally not subject to non-competition agreements.

In addition, we must attract and retain highly qualified personnel, including certain foreign nationals who are not U.S. citizens or permanent residents, many of whom are highly skilled and constitute an important part of our U.S. workforce, particularly in the areas of engineering and product development. Our ability to hire and retain these employees and their ability to remain and work in the U.S. are impacted by laws and regulations, as well as by procedures and enforcement practices of various government agencies. Changes in immigration laws, regulations or procedures, including those that may be enacted by the current U.S. presidential administration, may adversely affect our ability to hire or retain such workers, increase operating expenses and negatively impact our ability to deliver products and services, any of which would adversely affect our business, financial condition and results of operations.

The loss of one or more of our executive officers or other key personnel or our inability to locate suitable or qualified replacements could be significantly detrimental to product development efforts and could have a material adverse effect on our business, financial condition and results of operations.

Our operating results are subject to substantial quarterly and annual fluctuations.

Our operating results have fluctuated in the past and are likely to fluctuate in the future. These fluctuations may occur on a quarterly or annual basis and are due to a number of factors, many of which are beyond our control and are often difficult to predict. In addition, a significant amount of our operating expenses are relatively fixed in nature. Any failure to adjust spending quickly enough to compensate for a revenue shortfall could magnify the adverse impact of such revenue shortfall on our results of operations. As a result, quarter-to-quarter comparisons of our revenue and operating results may not be a meaningful or reliable indicator of our future performance.

27

USE OF PROCEEDS

All of the Class A common stock offered by the Selling Securityholders pursuant to this prospectus will be sold by the Selling Securityholders for their respective accounts. The Company will not receive any of the proceeds from these sales.

The Company will receive up to an aggregate of approximately $315.1million from the exercise of the warrants, assuming the exercise in full of all of the warrants for cash. The Company expects to use the net proceeds from the exercise such warrants for other general corporate purposes. There is no assurance that the holders of the warrants will elect to exercise any or all of such warrants. To the extent that warrants are exercised on a “cashless basis,” the amount of cash we would receive from the exercise of such warrants will decrease. See “Description of Securities” for additional information regarding the warrants.

The Selling Securityholders will pay any underwriting fees, discounts and selling commissions incurred by such Selling Securityholders in disposing of their Class A common stock. Pursuant to the Registration Rights Agreement, the Company will bear all other costs, fees and expenses incurred in effecting the registration of the Class A common stock covered by this prospectus, including, without limitation, all registration and filing fees, Nasdaq listing fees and fees and expenses of counsel and independent registered public accountants.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

1. Description of the Transactions

The Business Combination

On December14, 2020, Thunder Bridge II entered into the MTA with Surviving Pubco, the Merger Subs, indie, the ADK Blocker Group, ADK Service Provider Holdco and the indie Securityholder Representative.

As a result of the Domestication and the Business Combination, each issued and outstanding Class A ordinary share and Class B ordinary share of Thunder Bridge II was converted into a share of Class A common stock of the Company, and each issued and outstanding warrant to purchase Class A ordinary shares of Thunder Bridge II is exercisable by its terms to purchase an equal number of shares of Class A common stock of the Company.

Subject to the terms and conditions set forth in the MTA, at the Effective Time, the limited liability company interests of each indie Equity Holder automatically converted into the right to receive (i) the merger consideration consisting of either Class A common stock of the Company or the right to exchange Post-Merger indie Units into Class A common stock of the Company, and (ii) any shares of Class A common stock of the Company or Post-Merger indie Units issued pursuant to an earn-out as discussed elsewhere in this prospectus.

The merger consideration paid by Thunder Bridge II pursuant to the MTA was $894.6million, subject to adjustment, paid as an aggregate of 89,462,823shares of Class A common stock of the Company or rights to receive shares of Class A common stock of the Company (valued at $10.00 per share) or Post-Merger indie Units (valued at $10.00 per unit) (each of which units will be exchangeable on a one-for-one basis for shares of Class A common stock pursuant to the Exchange Agreement, subject to customary conversion rate adjustments, including common stock splits, stock dividends and reclassifications). The merger consideration was reduced by any amount that the Target Companies’ indebtedness at Closing exceeded the Target Companies’ cash and cash equivalents at Closing. Additionally, certain recipients of Post-Merger indie Units received an identical amount of shares of Class V common stock of the Company having no economic rights, each of which shares of Class V common stock entitles the holder thereof the right to one vote as a stockholder of the Company. After the six-month anniversary of the Closing, holders of Post-Merger indie Units will be permitted to exchange such units for shares of Class A common stock of the Company on a one-for-one basis pursuant to the Exchange Agreement (subject to customary conversion rate adjustments for stock splits, stock dividends and reclassifications), and upon any such conversion an identical number of Class V common stock shall be automatically cancelled.

In addition to the consideration set forth above, the indie Equity Holders and holders of Phantom Equity Units (once vested) will also have a contingent earn-out right to receive the Earn-Out Shares after the Closing based on the stock price of the Company at any time prior to December31, 2027 as set forth below:

•        If prior to December31, 2027, the volume weighted average price of the Class A common stock is greater than or equal to $12.50 over any 20 trading days within any 30 trading day period, the indie Equity Holders will be entitled to receive 5,000,000 Earn-Out Shares; and

•        If prior to December31, 2027, the volume weighted average price of the Class A common stock is greater than or equal to $15.00 over any 20 trading days within any 30 trading day period, the indie Equity Holders will be entitled to receive another 5,000,000 Earn-Out Shares.

Certain indie Equity Holders who hold Post-Merger indie Units and holders of Phantom Equity Units shall receive their respective share of the Earn-Out Shares as additional Post-Merger indie Units, calculated in accordance with the MTA and subject to exchange into Class A common stock pursuant to the Exchange Agreement.

Notwithstanding the foregoing, if there is a Company Sale (as defined in the MTA) after the Closing and prior to December31, 2027, where the implied per share consideration received by the stockholders of the Company in such sale is greater than $10.00 per share, then all of the remaining unpaid Earn-Out Shares will be deemed to be earned and paid out to the indie Equity Holders (less any Earn-Out Shares paid in satisfaction of certain transaction expenses).

35

The Earn-Out Shares issuable to indie Equity Holders are accounted for as contingent consideration in accordance with ASC 805, Business Combinations. The contingent consideration is not considered indexed to the Company’s own stock and is therefore classified as a liability in the unaudited pro forma condensed combined balance sheet and will be remeasured to fair value at each reporting date (see Note 5(i)).

The PIPE Financing

Contemporaneously with the execution of the MTA, Thunder Bridge II entered into separate Subscription Agreements with a number of subscribers (the “PIPE Investors”), pursuant to which the subscribers agreed to purchase, and Thunder Bridge II agreed to sell, an aggregate of up to 15,000,000shares of Class A common stock of the Company (the “PIPE Shares”), in a private placement for a purchase price of $10.00 per share and an aggregate purchase price of $150million (the “PIPE Financing”).

The closing of the sale of the PIPE Shares pursuant to the Subscription Agreements occurred concurrently Closing of the Business Combination. The purpose of the PIPE Financing was to raise additional capital for use by the Company following the Closing.

The Additional SAFE Agreement

During April 2021, indie entered into a simple agreement for future equity (SAFE) with a third-party investor for a total purchase amount of $5.0million (the “Additional SAFE Agreement”). The terms of the Additional SAFE Agreement are substantially the same as those issued in March and October 2020, except that the conversion cap is based on a $460million valuation cap. Such cap will be reduced to $350million if the Business Combination is not closed within 75 days of the funding of the Additional SAFE. The Additional SAFE Agreement issued in April 2021 has not been reflected in indie’s historical consolidated financial statements as of March31, 2021 but is a converting security with respect to the Business Combination.

2. Basis of Presentation

The unaudited pro forma condensed combined financial statements were prepared in accordance with Article 11 of SEC Regulation S-X as amended by the final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses.” Release No. 33-10786 replaces the existing pro forma adjustment criteria with simplified requirements to depict the accounting for the transaction (“Transaction Accounting Adjustments”) and present the reasonably estimable synergies and other transaction effects that have occurred or reasonably expected to occur (“Management’s Adjustments”). indie has elected not to present Management’s Adjustments and will only be presenting Transaction Accounting Adjustments in the unaudited pro forma condensed combined financial information. The adjustments presented in the unaudited pro forma condensed combined financial statements have been identified and presented to provide relevant information necessary for an understanding of the combined company upon consummation of the Business Combination, the PIPE Financing, and the Additional SAFE Agreement.

The unaudited pro forma condensed combined balance sheet as of March31, 2021 gives effect to the Business Combination, the PIPE Financing, and the Additional SAFE Agreement as if they occurred on March31, 2021. The unaudited pro forma condensed combined statements of operations for the three months ended March31, 2021 and for the year ended December31, 2020 give effect to the Business Combination, the PIPE Financing, and the Additional SAFE Agreement as if they occurred on January1, 2020, the beginning of the earliest period presented.

The pro forma adjustments reflecting the consummation of the Business Combination, the PIPE Financing, and the Additional SAFE Agreement are based on certain currently available information and certain assumptions and methodologies that indie believes are reasonable under the circumstances. indie believes that its assumptions and methodologies provide a reasonable basis for presenting all of the significant effects of the Business Combination, the PIPE Financing, and the Additional SAFE Agreement based on information available to management at this time and that the pro forma adjustments give appropriate effect to those assumptions and are properly applied in the unaudited pro forma condensed combined financial information.

36

The unaudited pro forma condensed combined financial information does not give effect to any anticipated synergies, operating efficiencies, tax savings, or cost savings that may be associated with the Business Combination. Thunder Bridge II and indie have not had any historical relationship prior to the Business Combination. Accordingly, no pro forma adjustments were required to eliminate activities between the companies. Amounts are presented in thousands, except for share and per share amounts or as otherwise specified.

The unaudited pro forma condensed combined financial information has been prepared using actual redemptions of 9,877,106 Thunder Bridge II outstanding ordinary shares for aggregate redemption payments of $100.1million out of the trust account on the closing date of the Business Combination. No other Thunder Bridge II ordinary shares are subject to redemption.

These unaudited pro forma condensed combined financial statements and related notes have been derived from and should be read in conjunction with:

•        the (i) audited historical financial statements of Thunder Bridge II as of and for the year ended December31, 2020 and (ii) unaudited historical condensed financial statements of Thunder Bridge II as of and for the three months ended March31, 2021 and the related notes, in each case, included elsewhere in the registration statement to which this prospectus forms a part;

•        the (i) audited historical consolidated financial statements of indie as of and for the year ended December31, 2020 and (ii) unaudited historical condensed consolidated financial statements of indie as of and for the three months ended March31, 2021 and the related notes, in each case, included elsewhere in the registration statement to which this prospectus forms a part; and

•        the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and other financial information included elsewhere in the registration statement to which this prospectus forms a part.

The unaudited pro forma condensed combined financial information is for illustrative purposes only and is not necessarily indicative of what the actual results of operations and financial position would have been had the Business Combination, the PIPE Financing, and the Additional SAFE Agreement taken place on the dates indicated, nor are they indicative of the future consolidated results of operations or financial position of the combined company.

3. Accounting for the Business Combination

The Business Combination will be accounted for as a reverse recapitalization, in accordance with GAAP. Under this method of accounting, although Thunder Bridge II issued shares for outstanding equity interests of indie in the Business Combination, Thunder Bridge II was be treated as the “acquired” company for financial reporting purposes. Accordingly, the Business Combination was treated as the equivalent of indie issuing stock for the net assets of Thunder Bridge II, accompanied by a recapitalization. The net assets of Thunder Bridge II were stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination will be those of indie.

indie has been determined to be the accounting acquirer based on the evaluation of the following facts and circumstances:

•        The former owners of indie hold the largest portion of voting rights in the combined company;

•        indie has the right to appoint a majority of the directors in the combined company;

•        indie’s existing senior management team will comprise senior management of the combined company;

•        The operations of the combined company will represent the operations of indie;

•        The combined company will assume indie’s name and headquarters.

MANAGEMENT’S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Unless the context otherwise requires, all references in this section to the “Company,” “we,” “us,” or “our” refer to the business of indie and its subsidiaries. Throughout this section, unless otherwise noted, “indie” refers to Ay Dee Kay, LLC, d/b/a indie Semiconductor, and its consolidated subsidiaries.

You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and the related notes appearing elsewhere in this prospectus. This discussion contains forward-looking statements that reflect our plans, estimates, and beliefs that involve risks and uncertainties. Certain amounts may not foot due to rounding. This discussion and analysis contains forward-looking statements and involves numerous risks and uncertainties, including, but not limited to, those described under the sections entitled “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” included in this prospectus. We assume no obligation to update any of these forward-looking statements except as required by law. Actual results may differ materially from those contained in any forward-looking statements.

Overview

indie offers highly innovative automotive semiconductors and software solutions for ADAS, including LiDAR, connected car, user experience and electrification applications. 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 we rely on every day. indie is an approved vendor to multiple 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, Boston, Massachusetts, Detroit, Michigan, San Francisco and San Jose, California, Dresden, Germany, Edinburgh, Scotland, and various locations in China.

Our go-to-market strategy focuses on collaborating with innovative customers and partnering with dozens of Tier 1 automotive suppliers through aligned new product development, in pursuit of solutions addressing the highest growth emerging technologies. We leverage our core capabilities in system-level hardware and software integration expertise to demonstrate to both existing and new customers, our ability to extend our current platform and scale into new products and markets.

Additionally, our innovative products are designed to meet or exceed the quality standards that are specified by the more than 20 global automotive manufacturers who utilize our devices. We support leading customers from our design and application centers located in North America, Asia and Europe, where our local teams work closely on customers’ unique design requirements.

We maintain design centers for our semiconductor engineers and designers in the United States, Scotland and China. We engage subcontractors to manufacture our products. These subcontractors, as well as the majority of our customers’ locations, are primarily in Asia. For the three months ended March31, 2021 and 2020, approximately 84% and 66%, respectively, of our product revenues were recognized for shipments to customer locations in Asia. For the years ended December31, 2020 and 2019, 75% and 86%, respectively, of the Company’s product revenues were recognized for shipments to customer locations in Asia.

Although revenue generated by each design win and the timing of the recognition of that revenue can vary significantly, we consider ongoing partnerships with Tier 1 automotive suppliers to be a key factor in our future success. A win occurs when our customer or contract manufacturer notifies us that it has selected our products to be incorporated into a product or system under development. We consider a design win to occur when an OEM or contract manufacturer notifies us that it has selected our products to be incorporated into a product or system under development. The design win process is typically lengthy, and our sales cycles will vary based on the market served, whether the design win is with an existing or new customer and whether our product is under consideration for inclusion in a first or subsequent generation product. In addition, our customers’ products that incorporate our semiconductors can be complex and can require a substantial amount of time to define, design and produce in volume. As a result, we can incur significant design and development expenditures in circumstances where we do not ultimately recognize, or experience delays in recognizing revenue. Our customers generally order our products on a purchase order basis. We generally do not have firm long-term purchase commitments (in excess of six months) from any of our customers. Once our product is incorporated into a customer’s design, however, we believe that our product is likely to continue

41

to be purchased for that design throughout that product’s life cycle because of the time and expense associated with redesigning the product or substituting an alternative semiconductor. Our design cycle from initial engagement to volume shipment is typically two to three years. Product life cycles in the markets we serve typically range from five to ten years and vary by application.

Since our inception, we have devoted substantially all of our efforts to organizing and staffing our company, research and development activities, producing devices and making sales to customers, raising capital and providing general and administrative support for these operations. Historically, we principally raised capital through the issuance and sale of our member units to outside investors in private equity financings, convertible debt financing and SAFEs. On June10, 2021, we completed the Business Combination with Thunder Bridge Acquisition II pursuant to the MTA. In connection with the Business Combination, Thunder Bridge II Surviving Pubco, Inc, a Delaware corporation (“Surviving Pubco”), was formed to be the successor public company to Thunder Bridge II, and a merger subsidiary of Surviving Pubco was merged with and into Thunder Bridge II. The most significant change in our future reported financial position and results is an estimated $400million in gross cash proceeds from the merger transaction and a net increase in cash (as compared to our consolidated balance sheet at December31, 2020) of approximately $335million. The estimate includes roughly $150million in proceeds from a private placement (“PIPE Investment”) that was consummated in conjunction with the Transaction, offset by additional transaction costs incurred in connection with the Business Combination “plus the retirement of indie’s long-term debt.

We have incurred significant operating losses since inception. Our net operating losses were $8.1million and $4.5million for the three months ended March31, 2021 and 2020, respectively, of which $0.5million and $0.3million, respectively, was attributable to the non-controlling interest. In addition, as of March31, 2021 and December31, 2020, we had an accumulated deficit of $142.4million and $153.3, respectively. Our net losses were $98.4million and $20.9million for the years ended December31, 2020 and 2019, respectively, of which $0.9million and $0.5million, respectively, was attributable to the non-controlling interest. In addition, as of December31, 2020 and 2019, we had an accumulated deficit of $153.3million and $55.8million, respectively.

As a result, we will need substantial additional funding to support our continuing operations, fund our product development plans, capital expenditure requirements and service our debt obligations. Until such time as we can achieve profitability, we expect to finance our operations through the sale of equity, debt financings, other capital sources, or a combination thereof.

Impact of COVID-19

In March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic (the “COVID-19 pandemic”), and the virus continues to spread in areas where we operate and sell our products and services. Several public health organizations have recommended, and many local governments have implemented, certain measures to slow and limit the transmission of the virus, including shelter in place and social distancing ordinances, which have resulted in a significant deterioration of economic conditions in many of the countries in which we operate.

The impact of the COVID-19 pandemic and the related disruptions caused to the global economy had a material impact on our business during the year ended December31, 2020 and for the three months ended March31, 2021. The semiconductor industry experienced supply chain interruptions, extended production lead times and higher costs, and, reduced capacity in customer and supplier manufacturing facilities. We experienced a decrease in customer demand and product shipments in the second quarter of fiscal year 2020. This decrease was primarily the result of closures or reduced capacity at customer manufacturing facilities in China. During the second half of fiscal year 2020, customer manufacturing facilities re-opened and the customer demand improved. We transitioned to a remote work environment for our employees since the second fiscal quarter of 2020 and have reduced discretionary spending. Given the increasing vaccination rates and reduced COVID-19 infections, the Company plans to transition most of its employees back to the office work environment during the third quarter of 2021. However, the Company cannot predict the duration or magnitude of the COVID-19 pandemic or the full impact that it may have on the Company’s financial condition, operations, and workforce. The Company will continue to actively monitor the rapidly evolving situation related to the COVID-19 pandemic and may take further actions that alter the Company’s operations, including those that may be required by federal, state or local authorities, or that the Company determines are in the best interests of its employees and other third parties with whom the Company does business.

42

As customer demand increased during the second half of fiscal year 2020, the semiconductor industry, and automotive semiconductors in particular, experienced material shortages and supply constraints. Given our reliance on third party manufacturing suppliers, these industry dynamics present a significant risk to us. As a result of the COVID-19 pandemic, it is possible that our business results and outcomes may differ from our estimates and assumptions.

Master Transaction Agreement

On December14, 2020, we entered into the MTA with Thunder Bridge II. Pursuant to the MTA, as amended on May31, 2021, we completed the Business Combination on June10, 2021.

The Business Combination is accounted for as a reverse recapitalization in accordance with US GAAP. Under the guidance in ASC 805, Thunder Bridge II is expected to be treated as the “acquired” company for financial reporting purposes. We are deemed the accounting predecessor of the combined business, and indie Semiconductor, Inc., as the parent company of the combined business, will be the successor SEC registrant, meaning that our financial statements for previous periods will be disclosed in the registrant’s future periodic reports filed with the SEC. The Business Combination has had a significant impact on our future reported financial position and results as a consequence of the reverse capitalization. The most significant changes in indie’s future reported financial position and results are expected to be an estimated net increase in cash (as compared to our consolidated balance sheet as of December31, 2020) of approximately $355million. See “Unaudited Pro Forma Condensed Combined Financial Information” elsewhere in this prospectus for additional information.

Results of Operations and Key Operating Metrics

Revenue

We design, develop and manufacture analog, digital and mixed signal ICs together with software running on the embedded processors in the majority of the ICs. Our revenue represents both non-recurring engineering (“NRE”) fees for the development of ICs and prototypes and product sales, the sale of semiconductors under separate commercial supply arrangements.

Our revenues fluctuate in response to a combination of factors, including the following:

•        our overall product mix and sales volumes;

•        gains and losses in market share and design win traction;

•        semiconductor content per vehicle;

•        pace at which technology is adopted in our end markets;

•        fluctuations in currency exchange rates that affect our prices;

•        the stage of our products in their respective life cycles;

•        the effects of competition and competitive pricing strategies;

•        governmental regulations influencing our markets; and

•        the global and regional economic cycles.

Product Revenue.    Our product revenue is recognized when the customer obtains control of the product and is based on the contractual shipping terms of a contract. We provide an assurance-type warranty which is not sold separately and does not represent a separate performance obligation. Therefore, the estimated costs of warranty claims are generally accrued as cost of goods sold in the period the related revenue is recorded. Under limited circumstances, we may offer an extended limited warranty to customers for certain products. We accrue for known warranty and indemnification issues if a loss is probable and can be reasonably estimated. The majority of our product revenue originates from sales shipped to customer locations in Asia, the United States, and Brazil.

43

Contract Revenue.    Contract revenue is revenue earned from non-recurring engineering services (“NRE”). Generally, our NRE contracts with our customers initially contain a single distinct performance obligation, which is to provide NRE design services for ICs based on the customer’s specifications. Generally, our contracts also include the optional purchase of ICs that may be exercised at stated prices subsequent to completion of NRE design services. We have determined that the option to purchase ICs is not a material right and have not allocated transaction price to this provision.

For NRE arrangements, we recognize revenue 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. 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.

Cost of Goods Sold

Cost of goods sold consists primarily of the cost of semiconductors purchased from subcontractors, including wafer fabrication, assembly, testing and packaging, board and device costs, manufacturing support costs, including labor and overhead associated with such purchases, final test yield fallout, inventory and warranty provisions, memory and component costs, and shipping costs. Cost of goods sold also includes compensation related to personnel associated with manufacturing. Cost of goods sold does not include development costs incurred related to servicing our NRE services contracts, which are recorded to research and development and expensed as incurred.

Research and Development Expense

Costs related to research, design, and development of our products are expensed as incurred. Research and development expense consists primarily of pre-production costs related to the design and development of our products and technologies, including costs related to NRE services contracts with customers such as employee compensation, benefits and related costs of sustaining our engineering teams, project material costs, third party fees paid to consultants, prototype development expenses, and other costs incurred in the product design and development process.

Selling, General, and Administrative Expense

Selling, general, and administrative costs include employee compensation, including compensation and benefits for executive, finance, accounting, legal, business operations and other administrative personnel. In addition, it includes marketing and advertising, outside legal, tax and accounting services, insurance, and occupancy costs and related overhead based on headcount. Selling, general, and administrative costs are expensed as incurred.

Interest Expense

Interest expense primarily consists of cash and non-cash interest under our term loan facilities, convertible notes and line of credit.

Other Expense

Other expense primarily comprises the change in the fair value of the SAFEs issued during 2020. The settlement or conversion of the SAFEs in conjunction with the Business Combination or another liquidity or financing transaction would eliminate the need for remeasurement of the instruments and thereby eliminate the other expense or income related to such.

Income Taxes

We are a limited liability company for U.S. federal income tax purposes and have elected to be treated as a partnership for income tax purposes. indie is not subject to income tax, but may be subject to certain tax fees imposed by the states. We record these tax fees as general and administrative expenses because they are not considered income taxes under ASC 740, Income Taxes. As such, all taxable income for indie is passed directly to the members, and is subject to income tax at the members’ level. Our subsidiary corporations may be subject to taxes. Refer to Note17, Income Tax, in our accompanying financial statements elsewhere in this prospectus. Our tax exposure through our subsidiaries is limited.

We expect research and development expense to continue to increase as we grow our headcount to support pent-up customer demand.

Selling, General and Administrative Expense

Selling, general and administrative expense for the three months ended March31, 2021 increased by $1.2million to $2.7million, or 81%, when compared to the three months ended March31, 2020. The increase is primarily due to a $0.4million increase in audit and tax consulting costs, $0.4million increased compensation expense related to headcount growth and $0.3million increase in the Transaction related expenses. We expect selling, general, and administrative expense to continue to increase as we grow our headcount to support our global expansion.

45

Interest Income

Interest income for the three months ended March31, 2021 increased by 17% from the three months ended March31, 2020. The increase was a result of higher cash balances held in interest bearing accounts.

Interest Expense

Interest expenses for the three months ended March31, 2021 was $0.6million, compared to $0.5million for the three months ended March31, 2020, an increase of $0.1million, or 12%. Interest expense relates primarily to interest on outstanding debt obligations and has increased based on the mix of outstanding debt and the associated interest rates.

Other Income (Expense)

Other expenses for the three months ended March31, 2021 increased to $19.4million, compared to the three months ended March31, 2020. The change was primarily due to the non-cash gain from the fair value of SAFEs as a result of changes in the valuation inputs in the current fiscal quarter.

Income Tax Expense

Income tax expenses for the three months ended March31, 2021 primarily a result of operations in the United Kingdom.

Liquidity and Capital Resources

The following table summarizes our consolidated cash flows for the three months ended March31, 2021 and 2020:

Net cash provided by (used in) investing activities		(161	)		(259	)
Net cash provided by (used in) financing activities		(632	)		4,130

Historically, we derive liquidity primarily from debt and equity financing activities as we have historically had negative cash flows from operations. As of March31, 2021, our balance of cash and cash equivalents was $8.9million, which is an increase of $4million or 82% compared to March31, 2020.

Our primary use of cash is to fund operating expenses, which consist primarily of research and development expenditures, working capital requirements related to inventory, accounts payable and accounts receivable, and general and administrative expenditures. In addition, we use cash to fund our debt service obligations, and purchases of capital and software assets.

We expect to continue to incur net operating losses and negative cash flows from operations and we expect our research and development expenses, general and administrative expenses and capital expenditures will continue to increase as we continue to expand our operations. We also anticipate our expenses and capital requirements to increase in connection with our ongoing initiatives to expand our operations, product offerings and customer base.

Research and Development Expense

Research and development expense for the year ended December31, 2020 increased by $1.8million to $22million, or 9%, as compared to the year ended December31, 2019. The increase is primarily driven by a $2.9million increase in the compensation costs as we increased the number of employees working on product development programs. However, there was a $1.1million decrease in amortization expense recognized for intangible assets attributable to research and development activities. We expect research and development expense to continue to increase as we grow our headcount to support our expansion.

Selling, General, and Administrative Expense

Selling, general, and administrative expense for the year ended December31, 2020 increased by $1.1million to $6.8million, or 19%, when compared to the year ended December31, 2019. The increase is primarily due to a $1.6million increase in legal, audit and tax consulting costs and increased compensation expense related to headcount growth. We expect selling, general, and administrative expense to continue to increase as we grow our headcount to support our expansion.

Interest Income

Interest income for the year ended December31, 2020 decreased $0.2million, or 86%, from the year ended December31, 2019. The decrease was the result of lower cash balances held in interest bearing accounts.

Interest Expense

Interest expenses for the year ended December31, 2020 was $2.2million, compared to $2.2million for the year ended December31, 2019, a decrease of less than $0.1million, or 1%. Interest expense relates primarily to interest on outstanding debt obligations and has decreased based on the mix of outstanding debt and the associated interest rates.

Other Income (Expense), Net

Other income (expense), net for the year ended December31, 2020 increased to $76.9million, compared to the year ended December31, 2019. The change was primarily due to $76.9million expense related to the recognition and change in the fair value of SAFEs.

Income Tax Expense

Income tax expenses for the year ended December31, 2020 and 2019 remained relatively consistent and are primarily a result of operations in the United Kingdom.

Liquidity and Capital Resources

Our primary use of cash is to fund operating expenses, which consist primarily of research and development expenditures, working capital requirements related to inventory, accounts payable and accounts receivable, and general and administrative expenditures. In addition, we use cash to fund our debt service obligations, and purchases of capital and software assets.

We expect to continue to incur net operating losses and negative cash flows from operations and we expect our research and development expenses, general and administrative expenses and capital expenditures will continue to increase as we continue to expand our operations. We expect our expenses and capital requirements to increase in connection with our ongoing initiatives to expand our operations, product offerings and customer base.

48

Historically, we have funded our operations primarily from the issuance and sale of preferred member units, convertible notes, and SAFEs. To date, we have raised $71.3million from these sources. We have also raised funds from term loans from multiple sources, of which $14.3million was outstanding as of December31, 2020. We have access to a revolving line of credit with Pacific Western Bank (formerly Square 1 Bank), for up to $2.0million, limited to a percentage of domestic accounts receivables less than 90 days past due, of which $1.7million is outstanding as of December31, 2020. We have also issued $5.6million of convertible notes and received a PPP Loan of $1.9million, as described below. In April 2021, we raised an additional $5.0million from the issuance of an additional SAFE, which is not reflected in the financial statements as of December31, 2020.

U.S. Small Business Administration’s Paycheck Protection Program

The Company participated in the Small Business Administration Payment Protection Plan (“PPP”) established by the Coronavirus Aid, Relief and Economic Security (“CARES”) Act, which was intended to provide economic relief to small businesses that have been adversely impacted by COVID-19.

In May 2020, the loan was approved and the Company received the proceeds from the loan in the amount of $1.9million (the “PPP Loan”). The PPP Loan took the form of a promissory note issued by the Company that matures in May 2022 and bears interest at a rate of 1.0% per annum. The Company accounts for the PPP Loan as part of long-term debt.

Cash Flows

Net cash provided by financing activities		33,474			125

We have historically funded our operations primarily from debt and equity financing activities as we have historically had negative cash flows from operations. As of December31, 2020, our balance of cash and cash equivalents was $18.7million, which is an increase of $11.5million or 161% compared to December31, 2019. The increase in cash year over year was mostly due to $25.8million of proceeds received from the issuance of SAFEs. Our total outstanding debt principal balance as of December31, 2020 was $21.6million, which represents an increase of $2.2million over the total debt outstanding as of December31, 2019 of $19.4million. The increase in outstanding debt principal consists of an additional $5.0million from proceeds from the issuance of debt and offset by payments on our existing debt obligations of $3.1million.

Operating Activities

Cash flows from operating activities during 2020 mostly consisted of net loss adjusted for certain non-cash items and changes in operating assets and liabilities. Non-cash adjustments primarily included $76.9million expense associated with the remeasurement of liabilities under SAFEs and $2.6million in depreciation and amortization.

Changes in the timing of collections have resulted in a decrease in cash from operating activities of $1.3million during 2020. Customer collections have slowed throughout 2020, though bad debts have decreased from $0.3 in 2019 to $0.1 in 2020. Decreases in inventory and increases in accounts payable and accrued expenses and other current liabilities were driven by the increasing linearity of revenue and the associated production in the fourth quarter of 2020 compared to the same period in 2019.

49

Cash used in operating activities during 2019 mostly consisted of net loss of $20.9million adjusted for certain non-cash items and changes in operating assets and liabilities. Non-cash charges primarily consisted of $4.0million in depreciation and amortization and $2.3million of inventory impairment charges.

Changes in the timing of supplier payments resulted in an increase in cash from operations of $3.0million that was offset by increases in inventory. Existing inventory increased during 2019 to align with anticipated future customer demand and represented $1.8million of cash used in operations.

Investing Activities

Net cash used in investing activities for the year ended December31, 2020 of $0.8million was primarily due to $0.6million used for the purchase of property and equipment. Purchases of property and equipment mostly consisted of production tooling used in production of ICs and office equipment associated with leasehold improvements at our Edinburgh, Scotland corporate office location.

Net cash used in investing activities for the year ended December31, 2019 of $2.2million was primarily due to $1.6million used for the purchase of property and equipment and $0.5million in payments for acquired software licenses. Purchases of property and equipment mostly consisted of research and development equipment for our lab facilities and office equipment across all our office locations. Purchases of software licenses related to software used in research and development for our products.

Financing Activities

Cash provided by financing activities during 2020 of $33.5million was primarily the result of $25.8million proceeds from SAFE note issued, $6.2million in proceeds from the sale of noncontrolling interest, $6.1million proceeds from the issuance of debt and offset by $4.2million payments on debt principal. During 2020, we entered into SAFEs with existing and new investors for gross proceeds of $25.8million and have used the proceeds to fund operations. From time to time, we have sold equity interest in our subsidiary, Wuxi, to raise funds to support operations. During 2020, we sold 13% of the outstanding equity for gross proceeds of $6.2million.

Cash provided by financing activities during 2019 of $0.1million was primarily the result of $2.6million in proceeds from the sale of noncontrolling interest, $0.3million in proceeds from the issuance of debt and offset by $2.0million payments on debt principal and $0.7million payments on financed software. Proceeds received from issuance of debt related to the outstanding debt obligation of our Chinese subsidiary, Wuxi, which used the proceeds to fund operations. During 2019, we sold 10% of the outstanding equity in our subsidiary, Wuxi, for gross proceeds of $2.6million to raise funds and support operations. Cash used in the financing activities includes repayment of outstanding debt principal in accordance with the terms of our loan agreements and payments for financed software purchases. During 2019, we have made payments for software used in the research and development that was purchased under financing arrangements.

Critical Accounting Policies and Estimates

The preparation of financial statements and related disclosures in accordance with U.S. GAAP requires our management to make judgments, assumptions and estimates that affect the amounts reported in our accompanying consolidated financial statements and the accompanying notes included elsewhere in this prospectus. Our management bases its estimates and judgments on historical experience, current economic and industry conditions and on various other factors that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

The methods, estimates, and judgments that we use in applying our accounting policies have a significant impact on the results that we report in our consolidated financial statements. Some of our accounting policies require us to make difficult and subjective judgments, often as a result of the need to make estimates regarding matters that are inherently uncertain.

Our most critical accounting estimates include revenue recognition, the valuation of inventory, and the fair value measurement of SAFEs.

50

Revenue Recognition

Prior to January1, 2019, we recognized revenue when there was persuasive evidence of an arrangement, delivery had occurred, the fee was fixed or determinable and collection was reasonably assured.

We adopted Financial Accounting Standards Board (“FASB”) Accounting Standard Update (“ASU”) 2014-09, Revenue from Contracts with Customers, on January1, 2019. The FASB subsequently issued several amendments and updates to the new revenue standard. We refer to ASU 2014-09 and its related ASUs as “ASC 606”. We applied ASC 606 using the modified retrospective method and elected to apply this initial application of the standard only to contracts that are not completed at the date of initial application. The cumulative effect of adopting ASC 606 resulted in a $4.0million adjustment to the opening balance of retained earnings as of January1, 2019, with an offsetting adjustment to deferred revenues.

Revenue is recognized when a customer obtains control of products or services in an amount that reflects the consideration which we expect to receive in exchange for those goods or services. To determine revenue recognition for arrangements within the scope of ASC 606, we perform the following five steps: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) we satisfy performance obligations. We recognize revenue when the control of the promised goods or services is transferred to customers in an amount that reflects the consideration we expect to receive in exchange for such goods or services.

The majority of our revenue is derived from the sale of semiconductor products. In determining the transaction price, we evaluate whether the price is subject to refund or adjustment to determine the net consideration to which we expect to be entitled.

Revenue is recognized when control of the product is transferred to the customer (i.e., when our performance obligation is satisfied), which is defined by the commercial terms of each purchase but typically occurs at shipment. In determining whether control has transferred, we consider if there is a present right to payment and legal title, and whether risks and rewards of ownership have transferred to the customer. Refer to Note 2 to our consolidated financial statements included elsewhere in this prospectus for additional discussion of our revenue recognition policy.

Inventories

Historically, the semiconductor industry has experienced periods of extreme volatility in product demand and in industry capacity, resulting in significant price fluctuations. This volatility has also resulted in significant fluctuations in price within relatively short timeframes.

Inventories are valued at the lower of cost or market. We regularly review our inventories and write down our inventories for estimated losses due to obsolescence. This allowance is determined for groups of products based on sales of our products in the recent past and/or expected future demand. Future demand is affected by market conditions, technological obsolescence, new products and strategic plans, each of which is subject to change with little or no forewarning. In estimating obsolescence, we utilize information that includes projecting future demand.

The need for strategic inventory levels to ensure competitive delivery performance to our customers are balanced against the risk of inventory obsolescence due to rapidly changing technology and customer requirements.

Valuation of SAFEs

The fair value of the SAFEs issued from March 2020 through December 2020 was estimated using a scenario-based analysis that estimates the fair value of the SAFEs based on the probability-weighted present value of expected future investment returns, considering each of the possible outcomes available to the noteholders, including conversions in various initial public offering, settlement, equity financing, corporate transaction and dissolution scenarios.

Off-Balance Sheet Commitments and Arrangements

As of December31, 2020 and as of March31, 2021, we did not have any off-balance sheet arrangements as defined in Item 303(a)(4)(ii) of Regulation S-K.

51

Recently Issued and Adopted Accounting Pronouncements

See Note 2 to both of our unaudited condensed financial statements and audited consolidated financial statements included elsewhere in this prospectus for a discussion of accounting pronouncements recently adopted and recently issued accounting pronouncements not yet adopted and their potential impact to our financial statements.

JOBS Act Accounting Election

We are an emerging growth company, as defined in the JOBS Act. The JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards applicable to public companies, allowing them to delay the adoption of those standards until those standards would otherwise apply to private companies. We have elected to use this extended transition period under the JOBS Act. As a result, following the Business Combination, our consolidated financial statements may not be comparable to the financial statements of companies that are required to comply with the effective dates for new or revised accounting standards that are applicable to public companies, which may make common stock less attractive to investors.

52

BUSINESS

Unless the context otherwise requires, all references in this section to “we,” “us,” “our,” “indie” or the “Company” refer to indie Semiconductor, Inc. and its consolidated subsidiaries.

indie Semiconductor, Inc.

indie offers highly innovative automotive semiconductors and software solutions for Advanced Driver Assistance Systems (“ADAS”), including LiDAR, connected car, user experience and electrification applications. 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 we 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, Boston, Massachusetts, Detroit, Michigan, San Francisco and San Jose, California, Dresden, Germany, Edinburgh, Scotland, and various locations throughout China.

Industry Overview

At the highest level, semiconductors can be classified either as discrete devices, such as individual transistors, or integrated circuits (“ICs”), where a number of transistors and other components are combined to form a more complicated electronic subsystem. ICs can be divided into three primary categories: digital, analog, and mixed-signal. Digital ICs, such as memory devices and microprocessors, can store or perform arithmetic functions with data. Analog ICs, by contrast, handle real-world signals such as temperature, pressure, light, sound or speed, and also perform power management functions such as regulating or converting voltages for electronic devices. Mixed-signal ICs combine digital and analog functions onto a single chip and play an important role in bridging real world inputs into the digital domain.

Historically, growth in the semiconductor industry has been driven by content expansion in computing, mobile and consumer electronics. However, research analysts anticipate that as each of these markets approach saturation, the automotive sector will become one of the fastest growing opportunities. Specifically, according to IHS research, the automotive semiconductor market is expected to grow from $33billion in 2020 to $59billion in 2025, representing a 12 percent Compound Annual Growth Rate (“CAGR”) compared to the overall semiconductor industry which, according to Fortune Business Insights, is expected to grow at a 5 percent CAGR over the same timeframe.

indie’s Market Opportunity

In today’s automobiles, semiconductors perform a variety of functions across multiple electronic components and systems, including sensing, processing data, storing information and converting or controlling signals. Semiconductor architectures vary significantly depending upon the specific function or application of the end product. They also differ based on a number of technical characteristics, including the degree of integration, level of customization, programmability and the underlying process technology utilized in manufacturing and assembly.

While semiconductors have always comprised the core building blocks of automotive electronic systems and equipment, recent technological advances have substantially increased their features, functionality and performance. Today, they support enhanced user interfaces and offer improved power consumption — all with reduced footprints and lower costs. These innovations have resulted in significant growth opportunities spanning diverse end markets and applications.

The twin technology megatrends driving the automotive semiconductor market are the rapid proliferation of electric vehicles (“EVs”) and adoption of ADAS functionality. Deloitte’s global EV forecast is for a 29 percent CAGR over the next 10 years, with total annual EV sales growing from 2.5million in 2020 to 31.1million by 2030, representing almost one third of all new car production. These estimated sales volumes are driven in part by increasing governmental mandates in Europe and Asia, along with similar new legislation in the United States. For example, special provisions in the United States Clean Air Act allow states to either follow the federal requirements or adopt California’s vehicle emission regulations. Currently, 10 states are following California and implementing its Zero Emission Vehicle (“ZEV”) regulations, including the requirements that about 10 percent of new vehicles must be ZEVs by 2025.Further, EVs are also benefitting from higher performance in terms of horsepower and range as well as compelling long-term economics resulting from decreased battery prices, lower lifetime maintenance costs and total cost of ownership.

53

At the same time, global ADAS volumes are expected to increase substantially, driven by consumer demand and government mandates for increased vehicle safety features. The European New Car Assessment Program (“NCAP”), which has been focused on fostering safe cars since 1996, requires a minimum level of crash mitigation functionality in new vehicles, such as Automatic Electronic Braking (“AEB”), Lane Keeping Assist (“LKA”) and other driver-assist features, in order for a vehicle to be awarded a 5-star rating. Similarly, the European Union is moving towards requiring speed assistance, driver drowsiness, attention-warning and driver distraction systems. In the United States, ADAS adoption and consumer education on advanced crash avoidance capabilities are being fueled by industry standards such as the U.S. NCAP and the Insurance Institute for Highway Safety “Top Safety Pick” and “Top Safety Pick+” awards. Additionally, the National Highway Traffic Safety Administration and 20 automakers recently pledged to voluntarily equip nearly all new passenger vehicles by September1, 2022, with low-speed AEB systems that include forward-collision warning. With global safety rating programs and auto manufacturers pushing to deliver more safety and comfort features to customers, many industry experts expect near complete adoption of ADAS functionalities in all new vehicles produced in Europe, the United States, Japan and South Korea by 2026.

indie’s addressable market is not solely dependent on global automotive volumes, but rather on the increased levels of semiconductor content that are required in vehicles to support safety systems, connected car, enhanced user experiences and EV applications as defined below:

•        Safety Systems:    Automotive safety features are evolving from passive to active systems, with the addition of ADAS and sensor technologies such as radar and vision. The path to Level 4 (high autonomy) and Level 5 (full autonomy) also contributes to ADAS adoption in vehicles today.

•        Connected Car:    Vehicles are increasingly called upon to communicate not only within the cabin, but also with external devices and networks. Smart car access, automotive Near-Field Communication (NFC) and Ultra-Wide Band (“UWB”) technologies, which enable the connection of vehicles and keys with external devices (including smart phones and vehicle to vehicle applications), are becoming increasingly standardized in baseline vehicle models rather than solely in the luxury or customized vehicles segments. Data integrity and security hardware features for safeguarding memory and other critical data are also becoming standard across all vehicle models, particularly as vehicles interface with external networks.

•        User Experience:    Comfort and convenience systems coupled with user interface applications, such as the inclusion of digital cockpits with multiple, large, interactive screens, require increased processing power. In addition, indie believes that consumer demand for the standardization of higher-end options across a greater number of vehicle classes, as well as complex internal vehicle customization, will drive higher semiconductor content.

•        Electrification:    Higher performance, broader availability of charging stations and more stringent emissions regulations are each accelerating the move toward electric vehicles.

Process and Packaging Technology

Packaging is becoming increasingly crucial to the performance and reliability of automotive ICs, especially given the challenging operating environment of vehicles. indie’s technology development engineers have long-established expertise in delivering leading edge capabilities, such as system-in-package (“SiP”) technology. Further, we leverage our proprietary packaging capabilities to integrate multiple chips into a single package solution.

Automotive Quality and Safety

We employ wafer and package technologies that meet or exceed the rigorous quality and safety requirements set by industry standards and our customers. Our robust development processes and company guidelines have resulted in indie devices that are capable of exceeding the requirements of AEC Q100 Automotive Grade.

Our dedication to our customers begins with a commitment to design, produce and deliver the highest quality products that meet or exceed the performance levels required for each application. We encourage our customers to frequently visit both our design centers and our manufacturing partners to ensure that the processes and quality meet the standards they have come to expect. We are ISO9001 certified and intend to pursue further certifications.

Intellectual Property

The core strengths of our business are our intellectual property portfolio and engineering experience, both of which guide product development activities and our approach to patent filings.

Our future success and competitive position depend in part upon our ability to obtain and maintain protection of our proprietary technologies. In general, we have elected to pursue patent protection for aspects of our circuit and device designs that we believe are patentable. We have a number of core technology patents currently in process, including provisions, but we do not rely on any particular patent or patents for our success and have instead relied on our know-how and trade secrets. We also rely on a combination of non-disclosure agreements and other contractual provisions, as well as our employees’ commitment to confidentiality and loyalty, to protect our technology and processes.

The semiconductor industry in general is characterized by frequent claims of infringement and litigation regarding patent and other intellectual property rights. Patent infringement is an ongoing risk, in part because other companies in our industry could have patent rights that may not be identifiable when we initiate development efforts. Litigation may be necessary to enforce our intellectual property rights, and we may have to defend ourselves against infringement claims.

Competition

The market for high-performance analog, digital and mixed-signal semiconductors for automotive applications, is competitive although recent consolidation across the semiconductor industry has reduced the number of viable competitors and created design opportunities for us. Our primary competitors are other automotive-focused semiconductor companies, including Infineon, Monolithic Power Systems, NXP, Renesas and ST Microelectronics.

Some competitors have more financial resources than we do, while others have a more diversified set of products and end markets. Accordingly, such competitors may be able to more quickly respond to customer requests and market developments, and to better withstand external economic or market factors.

However, we believe that our technical and design experience, our existing approved vendor list position across a dozen Tier 1 automotive suppliers, and a growing demand for software embedded solutions with proprietary manufacturing and packaging capabilities, position us to outpace our addressable market.

Employees

As of March31, 2021, we had 199 full-time employees. We believe that relations between our management and employees are good.

58

Manufacturing

We utilize a fabless business model, working with a network of third parties to manufacture, assemble and test our designs. This approach allows us to focus our engineering and design resources on our core competencies and to control and reduce our fixed costs and capital expenditures.

Wafers, which are the fundamental components of our devices, can be manufactured by multiple foundries. Having several sources provides us with an enhanced security of supply. Our primary manufacturing partners are X-FAB, HHGrace, ASE Group, and GlobalFoundries. We contract with X-FAB for mixed signal and high voltage foundry. HHGrace provides us deeper sub-micron capabilities with embedded Flash Memory. ASE Group is contracted for packaging and testing. We dual source packaging and testing locations at ASE Groups’ Taiwan and Shanghai facilities. We use GlobalFoundries as our foundry partner for several process technologies including advanced nodes.

Manufacturing is typically a 13-week cycle. The process begins by indie submitting a purchase order for wafers (which normally has a 70-day cycle), while simultaneously sending a forecast of demand to assembly and test partners so that they may order materials and secure capacity for indie, respectively. Assembly is a 10 to15 day process, while testing takes 1 to 5 days. The finished product is then warehoused and drop-shipped to a specific location. We currently ship products to China (Shanghai, Anting, Shenzhen and Changsha), Hong Kong, Taiwan, the United States, Portugal, Korea, Mexico, and Germany.

Design Centers and Other Facilities

Our headquarters is located in Aliso Viejo, California, with additional design, sales and support centers strategically located across Asia, Europe and North America. The map below outlines our specific locations. Our global footprint allows us to address customers’ needs while simultaneously attracting the talent needed to support our business.

Code of Ethics

We have adopted a Code of Ethics that applies to all of our employees, officers and directors, including our Chief Executive Officer, Chief Financial Officer and other executive and senior financial officers. The full text of our Code of Ethics is available on our website at investors.indiesemi.com under “Governance.” In addition, a copy of the Code of Ethics will be provided without charge upon request to us in writing at 32 Journey, Suite 100, Aliso Viejo, California 92656. Our Code of Ethics is a “code of ethics,” as defined in Item 406(b) of Regulation S-K. We will make any legally required disclosures regarding amendments to, or waivers of, provisions of our code of ethics on our website. The information contained on, or accessible from, our website is not part of this prospectus by reference or otherwise.

Board Composition

Our business affairs are managed under the direction of our board of directors. Our board of directors consists of nine members, seven of whom are independent within the meaning of the Nasdaq rules. Messrs. McClymont and Aoki are not considered independent.

Our board of directors is currently comprised of Donald McClymont, Ichiro Aoki, David Aldrich, Diane Brink, Peter Kight, Karl-Thomas Neumann, Jeffrey Owens, Sonalee Parekh and William Woodward.

63

Our board of directors is divided into three staggered classes of directors. At each annual meeting of our stockholders, a class of directors will be elected for a three-year term to succeed the same class whose term is then expiring, as follows:

•        the Class I directors are Sonalee Parekh, Ichiro Aoki and Jeffrey Owens and their terms will expire at the annual meeting of stockholders to be held in 2022;

•        the Class II directors are William Woodward, Karl-Thomas Neumann and Diane Brink and their terms will expire at the annual meeting of stockholders to be held in 2023; and

•        the Class III directors are Donald McClymont, Peter Kight and David Aldrich and their terms will expire at the annual meeting of stockholders to be held in 2024.

The Certificate of Incorporation provides that our board of directors will consist of one or more members, and the number of directors may be increased or decreased from time to time by a resolution of the board of directors provided that the number of directors constituting the whole board of directors shall not be more than nine. Each director’s term will continue until the election and qualification of his or her successor, or his or her earlier death, resignation, or removal. Any increase or decrease in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the total number of directors. This classification of the board of directors may have the effect of delaying or preventing changes in control of the Company.

Each of our officers will serve at the discretion of the board of directors and will hold office until his or her successor is duly appointed and qualified or until his or her earlier death, resignation or removal. There are no family relationships among any of our directors or officers.

Director Independence

Our Class A common stock is listed on Nasdaq. Under the rules of Nasdaq, independent directors must comprise a majority of a listed company’s board of directors. In addition, the rules of Nasdaq require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent. Under the rules of Nasdaq, a director will only qualify as an “independent director” if, in the opinion of that company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Audit committee members must also satisfy the additional independence criteria set forth in Rule 10A-3 under the Exchange Act and the rules of Nasdaq. Compensation committee members must also satisfy the additional independence criteria set forth in Rule 10C-1 under the Exchange Act and the rules of Nasdaq.

In order to be considered independent for purposes of Rule 10A-3 under the Exchange Act and under the rules of Nasdaq, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the committee, the board of directors, or any other board committee: (1) accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries; or (2) be an affiliated person of the listed company or any of its subsidiaries.

To be considered independent for purposes of Rule 10C-1 under the Exchange Act and under the rules of Nasdaq, the board of directors must affirmatively determine that the member of the compensation committee is independent, including a consideration of all factors specifically relevant to determining whether the director has a relationship to the company which is material to that director’s ability to be independent from management in connection with the duties of a compensation committee member, including, but not limited to: (i) the source of compensation of such director, including any consulting, advisory or other compensatory fee paid by the company to such director; and (ii) whether such director is affiliated with the company, a subsidiary of the company or an affiliate of a subsidiary of the company.

Our board of directors has undertaken a review of the independence of each director and considered whether each of our directors has a material relationship with the Company that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. As a result of this review, we have determined that Messrs. Aldrich, Kight, Neumann, Owens and Woodward, and Ms. Brink and Ms. Parekh are considered “independent directors” as defined under the listing requirements and rules of Nasdaq and the applicable rules of the Exchange Act.

64

Each of the members of our audit committee satisfies the requirements for independence and financial literacy under the applicable rules and regulations of the SEC and rules of Nasdaq.

EXECUTIVE COMPENSATION

This section discusses the material components of the executive compensation programs for our named executive officers (identified below). This discussion may contain forward- looking statements that are based on our current plans, considerations, expectations and determinations regarding future compensation programs. Actual compensation programs that we adopt may differ materially from the existing and currently planned programs summarized or referred to in this discussion.

We have opted to comply with the executive compensation disclosure rules applicable to emerging growth companies, as we are an emerging growth company. The scaled down disclosure rules are those applicable to “smaller reporting companies,” as such term is defined in the rules promulgated under the Securities Act, which require compensation disclosure for our principal executive officer and our two most highly compensated executive officers other than the principal executive officer, who were serving as executive officers as of December31, 2020. Since the Company is a newly-formed entity that recently became a public company on June10, 2021 as a result of the Business Combination, we have provided the compensation awarded to, earned by or paid to the CEO and the two most highly compensated executive officers of ADK LLC while employed by ADK LLC for the years ended December31, 2020 and 2019. (the “named executive officers”). Each of such persons currently hold the same positions with the Company.

Donald McClymont was our principal executive officer of ADK LLC for the entirety of fiscal 2020 and fiscal 2019. Our two most highly compensated executive officers that were serving in such capacity at the end of fiscal year 2019 (other than Mr.McClymont) were Ichiro Aoki and Scott Kee. Our three most highly compensated executive officers that were serving in such capacity at the end of fiscal 2020 (other than Mr.McClymont) were Thomas Schiller, Ichiro Aoki and Scott Kee.

Therefore, for the fiscal year ended December31, 2020, our named executive officers were:

•        Donald McClymont, Chief Executive Officer;

•        Ichiro Aoki, President;

•        Thomas Schiller, Chief Financial Officer and Executive Vice President of Strategy; and

•        Scott Kee, Chief Technology Officer.

(1)      This grant includes both performance-based stock awards and time based awards granted in fiscal 2020. The fair value of these awards represents the estimated grant date fair value of the stock awards as determined under the provisions of FASB Accounting Standard Codification Topic 718. Such estimated fair value amounts do not necessarily correspond to the potential actual value realized from the stock awards. The assumptions made in computing the estimated fair value of such stock awards are discussed in Note 13 of the accompanying financial statements. In 2020, Mr. Schiller received a grant of 75,000 Class B LLC units of ADK LLC, which had five individual vesting schedules as follows:

•        26,000 units vest as to 25% of the shares on the anniversary of the grant date and thereafter vests as to the remaining 75% of the shares monthly in equal installments over a three year period;

•        25,000 units vest in its entirety on the date of successful closing of the Business Combination;

67

•        12,000 units vest in its entirety upon the Company’s achievement of at least $150,000,000 in trailing twelve-month revenue;

•        6,000 units vest in its entirety upon the completion of a capital raise in the amount of at least $50,000,000 with a minimum pre-money valuation of $350,000,000 as determined in the financing round (which shares vested in full at the closing of the Business Combination); and

•        6,000 units vest in its entirety upon the Company’s achievement of at least $50,000,000 in trailing twelve-month revenue.

(2)      In connection with the Business Combination, the 75,000 Class B LLC units of ADK LLC were split into an aggregate of 2,085,019 Class B LLC Units and then were converted into 2,085,019shares of the Company’s Class A common stock.

(3)      Amount consists of Company matching contributions under the 401(k) Plan in the amount of $8,800, $0, $11,200, and $0 for Messrs. McClymont, Aoki, Schiller and Kee, respectively. Each of such officer also was provided with Armadacare, which is an executive medical cost reimbursement program, which program costs $6,622, $3,509, $10,144 and $3,509 for Messrs. McClymont, Aoki, Schiller and Kee, respectively, which was paid for by the Company.

(4)      Mr.Thomas Schiller’s service as our Chief Financial Officer and Executive Vice President of Strategy commenced in October 2019, and as a result, his salary was prorated based on an annual balance of $300,000.

Employment Arrangements with Named Executive Officers

None of Messrs. McClymont, Schiller, Aoki or Kee had an employment agreement with us during fiscal 2020 and fiscal 2019. Mr.Thomas Schiller’s service as our Chief Financial Officer and Executive Vice President of Strategy commenced in October 2019, and as a result, he was not one of the two most highly compensated executive officers after Mr.McClymont during fiscal 2019. In connection with the Business Combination, we indicated that we intend to enter into employment agreements with each of our executive officers on mutually acceptable terms upon the consummation of the Business Combination.

2020 Equity-Based Compensation

Class B Units

We have entered into Class B Unit Purchase Agreements with certain employees and executives pursuant to which we awarded Class B Units. Class B Units provide for the grant of “profits interests” that give the grantee the right to participate in future profits and appreciation in the value of ADK LLC. The profits interests generally vest over four years, with 25% vesting on the first anniversary of the grant date and the remainder vesting in equal monthly installments over the next three years. The agreements provide for double trigger accelerated vesting if there is a change of control and the grantee’s employment is terminated other than for “cause” or if the grantee resigns for “good reason” as defined in such agreements.

Treatment of Class B Units in Business Combination

Mr.Schiller, our Chief Financial Officer, is the only named executive officer who received Class B LLC Units in ADK LLC. In 2020, Mr.Schiller contributed all of his 75,000 LLC Units to ADK Service Provider Holdco LLC (“Holdco”) in exchange for shares of common stock in Holdco. In connection with the Business Combination, all of Mr.Schiller’s Holdco shares were exchanged and converted into 2,085,019shares of Class A common stock of the Company, 937,100 of which were unvested as of the Closing.

Equity Incentive Plan

The 2021 Omnibus Equity Incentive Plan (the “Equity Incentive Plan”) is a comprehensive incentive compensation plan under which we can grant equity-based and other incentive awards to our officers, employees, directors, consultants and advisers. The purpose of the Equity Incentive Plan is to help us attract, motivate and retain such persons with awards under the Equity Incentive Plan and thereby enhance shareholder value.

Administration.    The Equity Incentive Plan is administered by the compensation committee of our board of directors, which consists of three members of our board of directors, each of whom is a “non-employee director” within the meaning of Rule 16b-3 promulgated under the Exchange Act and “independent” for purposes of Nasdaq requirements. If a member of the compensation committee is eligible to receive an award under the Equity Incentive Plan, such compensation committee member shall have no authority under the plan with respect to his or her own award. Among other things, the compensation committee has complete discretion, subject to the express limits of the Equity Incentive Plan, to determine the directors, employees and nonemployee consultants to be granted an award,

68

the type of award to be granted, the terms and conditions of the award, the form of payment to be made and/or the number of shares of common stock subject to each award, the exercise price of each option and base price of each stock appreciation right (“SAR”), the term of each award, the vesting schedule for an award, whether to accelerate vesting, the value of the common stock underlying the award, and the required withholding, if any. The compensation committee may amend, modify or terminate any outstanding award, provided that the participant’s consent to such action is required if the action would impair the participant’s rights or entitlements with respect to that award. The compensation committee is also authorized to construe the award agreements, and may prescribe rules relating to the Equity Incentive Plan. Notwithstanding the foregoing, the compensation committee does not have any authority to grant or modify an award under the Equity Incentive Plan with terms or conditions that would cause the grant, vesting or exercise thereof to be considered nonqualified “deferred compensation” subject to Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), unless such award is structured to be exempt from or comply with all requirements of Code Section 409A.

Grant of Awards; Shares Available for Awards.    The Equity Incentive Plan provides for the grant of stock options, SARs, performance share awards, performance unit awards, distribution equivalent right awards, restricted stock awards, restricted stock unit awards and unrestricted stock awards to non-employee directors, officers, employees and consultants of the Company or its affiliates. The aggregate number of shares of common stock reserved and available for grant and issuance under the Equity Incentive Plan is 10,368,750. No more than 10,368,750shares of common stock in the aggregate may be issued under the Equity Incentive Plan in connection with incentive stock options. Shares shall be deemed to have been issued under the Equity Incentive Plan solely to the extent actually issued and delivered pursuant to an award. If any award expires, is cancelled, or terminates unexercised or is forfeited, the number of shares subject thereto is again available for grant under the Equity Incentive Plan. The Equity Incentive Plan shall continue in effect, unless sooner terminated, until the tenth (10th) anniversary of the date on which it was adopted by our board of directors. The board of directors in its discretion may terminate the Equity Incentive Plan at any time with respect to any shares for which awards have not theretofore been granted; provided, however, that the Equity Incentive Plan’s termination shall not materially and adversely impair the rights of a holder, without the consent of the holder, with respect to any award previously granted.

Stock Options.    The Equity Incentive Plan provides for either “incentive stock options” (“ISOs”), which are intended to meet the requirements for special federal income tax treatment under Section 422 of the Code, or “nonqualified stock options” (“NQSOs”).

Stock options may be granted on such terms and conditions as the compensation committee may determine, which shall be specified in the option agreement; provided, however, that the per share exercise price under a stock option may not be less than the fair market value of a share of common stock on the date of grant and the term of the stock option may not exceed 10 years (110% of such value and five years in the case of an ISO granted to an employee who owns (or is deemed to own) more than 10% of the total combined voting power of all classes of our capital stock or that of a parent or subsidiary).

ISOs may only be granted to employees. In addition, the aggregate fair market value of common stock covered by one or more ISOs (determined at the time of grant), which are exercisable for the first time by an employee during any calendar year may not exceed $100,000. Any excess is treated as a NQSO.

No ISO shall be granted to an employee if, at the time the ISO is granted, such employee owns shares possessing more than ten percent (10%) of our total combined voting power, unless (i) at the time such ISO is granted the option price is at least one hundred ten percent (110%) of the fair market value of the shares subject to the ISO, and (ii) such ISO by its terms is not exercisable after the expiration of five (5) years from the date of grant.

No ISO shall be granted more than ten (10) years from the earlier of the effective date of the Equity Incentive Plan or the date on which the Equity Incentive Plan was approved by the Thunder Bridge II shareholders.

Stock Appreciation Rights.    A SAR entitles the participant, upon exercise, to receive an amount, in cash or stock or a combination thereof, equal to the increase in the fair market value of the underlying common stock between the date of grant and the date of exercise. The compensation committee shall set forth in the applicable SAR award agreement the terms and conditions of the SAR, including the base value for the SAR (which shall not be less than the fair market value of a share on the date of grant), the number of shares subject to the SAR and the period during which the SAR may be exercised and any other special rules and/or requirements which the compensation committee imposes on the SAR. No SAR shall be exercisable after the expiration of ten (10) years from the date of grant. SARs

69

may be granted in tandem with, or independently of, stock options granted under the Equity Incentive Plan. A SAR granted in tandem with a stock option: (i) is exercisable only at such times, and to the extent, that the related stock option is exercisable in accordance with the procedure for exercise of the related stock option; (ii) terminates upon termination or exercise of the related stock option (likewise, the common stock option granted in tandem with a SAR terminates upon exercise of the SAR); (iii) is transferable only with the related stock option; and (iv) if the related stock option is an ISO, may be exercised only when the value of the stock subject to the stock option exceeds the exercise price of the stock option. A SAR that is not granted in tandem with a stock option is exercisable at such times as the compensation committee may specify.

Performance Shares and Performance Unit Awards.    Performance share and performance unit awards entitle the participant to receive cash or shares of common stock upon the attainment of specified performance goals. In the case of performance units, the right to acquire the units is denominated in cash values. The compensation committee shall set forth in the applicable award agreement the performance goals and objectives and the period of time to which such goals and objectives shall apply. If such goals and objectives are achieved, such distribution of shares, or payment in cash, as the case may be, shall be made no later than by the fifteenth (15th) day of the third (3rd) calendar month next following the end of our fiscal year to which such performance goals and objectives relate, unless otherwise structured to comply with Code Section 409A.

Distribution Equivalent Right Awards.    A distribution equivalent right award entitles the participant to receive bookkeeping credits, cash payments and/or common stock distributions equal in amount to the distributions that would have been made to the participant had the participant held a specified number of shares of common stock during the period the participant held the distribution equivalent right. A distribution equivalent right may be awarded as a component of another award (but not an option or SAR award) under the Equity Incentive Plan, where, if so awarded, such distribution equivalent right will expire or be forfeited by the participant under the same conditions as under such other award. The compensation committee shall set forth in the applicable distribution equivalent rights award agreement the terms and conditions, if any, including whether the holder is to receive credits currently in cash, is to have such credits reinvested (at fair market value determined as of the date of reinvestment) in additional shares, or is to be entitled to choose among such alternatives.

Restricted Stock Awards.    A restricted stock award is a grant or sale of common stock to the holder, subject to such restrictions on transferability, risk of forfeiture and other restrictions, if any, as the compensation committee or the board of directors may impose, which restrictions may lapse separately or in combination at such times, under such circumstances (including based on achievement of performance goals and/or future service requirements), in such installments or otherwise, as the compensation committee or the board of directors may determine at the date of grant or purchase or thereafter. If provided for under the restricted stock award agreement, a participant who is granted or has purchased restricted stock shall have all of the rights of a stockholder, including the right to vote the restricted stock and the right to receive dividends thereon (subject to any mandatory reinvestment or other requirement imposed by the compensation committee or the board of directors or in the award agreement). During the restricted period applicable to the restricted stock, subject to certain exceptions, the restricted stock may not be sold, transferred, pledged, exchanged, hypothecated, or otherwise disposed of by the participant.

Restricted Stock Unit Awards.    A restricted stock unit award provides for a grant of shares or a cash payment to be made to the holder upon the satisfaction of predetermined individual service-related vesting requirements, based on the number of units awarded to the holder. The compensation committee shall set forth in the applicable restricted stock unit award agreement the individual service-based vesting requirements which the holder would be required to satisfy before the holder would become entitled to payment and the number of units awarded to the holder. The holder of a restricted stock unit shall be entitled to receive a cash payment equal to the fair market value of a share of common stock, or one share of common stock, as determined in the sole discretion of the compensation committee and as set forth in the restricted stock unit award agreement, for each restricted stock unit subject to such restricted stock unit award, if and to the extent the holder satisfies the applicable vesting requirements. Such payment or distribution shall be made no later than by the fifteenth (15th) day of the third (3rd) calendar month next following the end of the calendar year in which the restricted stock unit first becomes vested, unless otherwise structured to comply with Code Section 409A. A restricted stock unit shall not constitute an equity interest in the Company and shall not entitle the holder to voting rights, dividends or any other rights associated with ownership of shares prior to the time the holder shall receive a distribution of shares.

70

Unrestricted Stock Awards.    An unrestricted stock award is a grant or sale of shares of our common stock to the employees, non-employee directors or non-employee consultants that are not subject to transfer, forfeiture or other restrictions, in consideration for past services rendered to us or an affiliate or for other valid consideration.

Change-in-Control Provisions.    The compensation committee may, in its sole discretion, at the time an award is granted or at any time prior to, coincident with or after the time of a change in control, cause any award either (i) to be canceled in consideration of a payment in cash or other consideration in amount per share equal to the excess, if any, of the price or implied price per share of common stock in the change in control over the per share exercise, base or purchase price of such award, which may be paid immediately or over the vesting schedule of the award; (ii) to be assumed, or new rights substituted therefore, by the surviving corporation or a parent or subsidiary of such surviving corporation following such change in control; (iii) to have its time periods accelerated, or waive any other conditions, relating to the vesting, exercise, payment or distribution of an award so that any award to a holder whose employment has been terminated as a result of a change in control may be vested, exercised, paid or distributed in full on or before a date fixed by the compensation committee; (iv) to be purchased from a holder whose employment has been terminated as a result of a change in control, upon the holder’s request, for an amount of cash equal to the amount that could have been obtained upon the exercise, payment or distribution of such rights had such award been currently exercisable or payable; or (v) terminate any then outstanding award or make any other adjustment to the awards then outstanding as the compensation committee deems necessary or appropriate to reflect such transaction or change. The number of shares subject to any award shall be rounded to the nearest whole number.

Amendment and Termination.    The compensation committee may adopt, amend and rescind rules relating to the administration of the Equity Incentive Plan, and amend, suspend or terminate the Equity Incentive Plan, but no such amendment or termination will be made that materially and adversely impairs the rights of any participant with respect to any award received thereby under the Equity Incentive Plan without the participant’s consent, other than amendments that are necessary to permit the granting of awards in compliance with applicable laws.

Certain U.S. Federal Income Tax Consequences of the Equity Incentive Plan

The following is a general summary of certain U.S. federal income tax consequences under current tax law to us (to the extent it is subject to U.S. federal income taxation on its net income) and to participants in the Equity Incentive Plan who are individual citizens or residents of the United States for federal income tax purposes (“U.S. Participants”) of stock options which are ISOs, or stock options which are NQSOs, unrestricted stock, restricted stock, restricted stock units, performance stock, performance units, SARs, and dividend equivalent rights. This summary does not purport to cover all of the special rules that may apply, including special rules relating to limitations on our ability to deduct certain compensation, special rules relating to deferred compensation, golden parachutes, U.S. Participants subject to Section 16(b) of the Exchange Act or the exercise of a stock option with previously-acquired shares. This summary assumes that U.S. Participants will hold their shares as capital assets within the meaning of Section 1221 of the Code. In addition, this summary does not address the foreign, state or local or other tax consequences, or any U.S. federal non-income tax consequences, inherent in the acquisition, ownership, vesting, exercise, termination or disposition of an award under the Equity Incentive Plan, or ordinary shares issued pursuant thereto. Participants are urged to consult with their own tax advisors concerning the tax consequences to them of an award under the Equity Incentive Plan or shares issued thereunder pursuant to the Equity Incentive Plan.

A U.S. Participant generally does not recognize taxable income upon the grant of a NQSO if structured to be exempt from or comply with Code Section 409A. Upon the exercise of a NQSO, the U.S. Participant generally recognizes ordinary compensation income in an amount equal to the excess, if any, of the fair market value of the shares acquired on the date of exercise over the exercise price thereof, and the Company generally will be entitled to a deduction for such amount at that time. If the U.S. Participant later sells shares acquired pursuant to the exercise of a NQSO, the U.S. Participant recognizes a long-term or short-term capital gain or loss, depending on the period for which the shares were held. A long-term capital gain is generally subject to more favorable tax treatment than ordinary income or a short-term capital gain. The deductibility of capital losses is subject to certain limitations.

A U.S. Participant generally does not recognize taxable income upon the grant or, except for purposes of the U.S. alternative minimum tax (“AMT”) the exercise, of an ISO. For purposes of the AMT, which is payable to the extent it exceeds the U.S. Participant’s regular income tax, upon the exercise of an ISO, the excess of the fair market value of the shares subject to the ISO over the exercise price is a preference item for AMT purposes. If the U.S. Participant disposes of the shares acquired pursuant to the exercise of an ISO more than two years after the date of grant and more than one year after the transfer of the shares to the U.S. Participant, the U.S. Participant generally recognizes a long-term capital gain or loss, and we will not be entitled to a deduction. However, if the U.S. Participant disposes of such shares prior to the end of either of the required holding periods, the U.S. Participant will have ordinary compensation income equal to the excess (if any) of the fair market value of such shares on the date of exercise (or, if less, the amount realized on the disposition of such shares) over the exercise price paid for such shares, and we generally will be entitled to deduct such amount.

A U.S. Participant generally does not recognize income upon the grant of a SAR. The U.S. Participant recognizes ordinary compensation income upon exercise of the SAR equal to the increase in the value of the underlying shares, and we generally will be entitled to a deduction for such amount.

A U.S. Participant generally does not recognize income on the receipt of a performance stock award, performance unit award, restricted stock unit award, unrestricted stock award or dividend equivalent rights award until a cash payment or a distribution of shares is received thereunder. At such time, the U.S. Participant recognizes ordinary compensation income equal to the excess, if any, of the fair market value of the shares or the amount of cash received over any amount paid therefor, and we generally will be entitled to deduct such amount at such time.

A U.S. Participant who receives a restricted stock award generally recognizes ordinary compensation income equal to the excess, if any, of the fair market value of such shares at the time the restriction lapses over any amount paid for the shares. Alternatively, the U.S. Participant may make an election under Section 83(b) of the Code to be taxed on the fair market value of such shares at the time of grant. We generally will be entitled to a deduction at the same time and in the same amount as the income that is required to be included by the U.S. Participant.

Tax Advice

The preceding discussion is based on U.S. tax laws and regulations presently in effect, which are subject to change, and the discussion does not purport to be a complete description of the U.S. income tax aspects of the Equity Incentive Plan. A participant may also be subject to state and local taxes in connection with the grant of awards under the Equity Incentive Plan. In addition, if a participant resides outside the United States, the participant may be subject to taxation in other countries. The actual tax implications for any participant will depend on the legislation in the relevant tax jurisdiction for that Participant and their personal circumstances.

Tax-Qualified Retirement Plan

We maintain a defined contribution 401(k) plan for our executives and employees, which allows them to defer a percentage of their compensation on a tax-free basis. We match 100% of a participant’s elective deferrals up to 3% of eligible compensation for the plan year, plus 50% of the portion of a participant’s elective deferrals that exceeds 3%, but not to exceed 5% of eligible compensation for the plan year. Participants are always 100% vested in their elective deferrals and our matching contributions. The 401(k) plan also contains a Roth IRA component.

(1)      As of December 31, 2020, all shares previously granted to Messrs. McClymont, Aoki and Kee were fully vested.

(2)      Units vest as to 25% of the shares on the anniversary of the grant date and thereafter vests as to the remaining 75% of the shares monthly in equal installments over a three year period.

(3)      Units vest in their entirety on the date of successful closing of the Business Combination.

(4)      Units vest in their entirety upon the Company’s achievement of at least $150,000,000 in trailing twelve-month revenue.

(5)      Units vest in their entirety upon the completion of a capital raise in the amount of at least $50,000,000 with a minimum pre-money valuation of $350,000,000 as determined in the financing round.

(6)      Units vest in their entirety upon the Company’s achievement of at least $50,000,000 in trailing twelve-month revenue.

(7)      The fair value of these awards represents the valuation of Class B LLC units of ADK LLC as of December 31, 2020. Since the Company was not a publicly-traded company at that time, this calculation was based on the $10 per share valuation of the Company’s Class A common stock pursuant to the MTA. Upon closing of the Business Combination on June 10, 2021, the Class B LLC Units of ADK LLC were split into 2,085,019 Class B LLC Units and then were converted into 2,085,019 shares of Class A common stock.

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

Unless the context otherwise requires, all references in this section to “we,” “us,” “our,” “indie” or the “Company” refer to indie Semiconductor, Inc. and its consolidated subsidiaries.

Exchange Agreement

Concurrently with the completion of the Business Combination, Surviving Pubco entered into an Exchange Agreement with certain holders of Post-Merger indie Units, including Messrs. Aoki, McClymont, Schiller and Kee, which provides for the exchange of such holders’ Post-Merger indie Units into shares of our Class A common stock.

Exchange Mechanics

Certain holders of Post-Merger indie Units are, from and after the six-month anniversary of the Closing, at any time and from time to time, able to exchange all or any portion of their Post-Merger indie Units for shares of our Class A common stock by delivering a written notice to us; provided, that we may, in our sole and absolute discretion, in lieu of delivering shares of Class A common stock for any Post-Merger indie Units surrendered for exchange, pay an amount in cash per Post-Merger indie Unit equal to the volume weighted average price of the Class A common stock on the date of the receipt of the written notice of the exchange. Certain holders of Post-Merger indie Units that hold Class B Units of ADK LLC will not be able to exchange their units under the Exchange Agreement until the later of six months from the Closing or the second anniversary of the most recent Class B Unit award.

Exchange Ratio

The initial exchange ratio was one Post-Merger indie Unit for one share of Class A common stock. The exchange ratio will be adjusted for any subdivision (split, unit distribution, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse unit split, reclassification, reorganization, recapitalization or otherwise) of the Post-Merger indie Units that is not accompanied by an identical subdivision or combination of the Class A common stock or, by any such subdivision or combination of the Class A common stock that is not accompanied by an identical subdivision or combination of the Post-Merger indie Units. If our Class A common stock is converted or changed into another security, securities or other property, on any subsequent exchange an exchanging holder of Post-Merger indie Units will be entitled to receive such security, securities or other property. The exchange ratio will also adjust in certain circumstances when we acquire Post-Merger indie Units other than through an exchange for shares of Class A common stock.

Restrictions on Exchange

We may refuse to effect an exchange if we determine that an exchange would violate applicable law (including securities laws). We may also limit the rights of holders of Post-Merger indie Units to exchange their Post-Merger indie Units under the Exchange Agreement if we determine in good faith that such restrictions are necessary so that we will not be treated as a “publicly traded partnership” under applicable tax laws and regulations. In addition, holders of Post-Merger indie Units that hold Class B Units of ADK LLC will not be able to exchange their units under the Exchange Agreement until the later of six months from the Closing or the second anniversary of the most recent Class B Unit award.

Expenses

The Company and each holder of Post-Merger indie Units will bear its own expense regarding the exchange except that we will be responsible for transfer taxes, stamp taxes and similar duties (unless the holder has requested the shares of Class A common stock to be issued in the name of another holder).

The form of Exchange Agreement is included as an exhibit to the registration statement for which this prospectus forms a part and is incorporated by reference herein.

Tax Receivable Agreement

Concurrently with the completion of the Business Combination, Surviving Pubco entered into the Tax Receivable Agreement with certain indie Equity Holders.

74

Holders of Post-Merger indie Units that are party to the Exchange Agreement (other than the Company) may, subject to certain conditions, from and after the six-month anniversary of the date of the completion of the Business Combination, exchange their Post-Merger indie Units for shares of our Class A common stock on a one-for-one basis, subject to the terms of the Exchange Agreement, including in certain cases, adjustments as set forth therein. We intend to have in effect an election under Section 754 of the Code for each taxable year in which an exchange of Post-Merger indie Units for shares of Class A common stock occurs, which we expect will result in increases to the tax basis of ADK LLC’s assets at the time of an exchange of Post-Merger indie Units. The exchanges are expected to result in increases in the tax basis of ADK LLC’s tangible and intangible assets. These increases in tax basis may reduce the amount of tax that we would otherwise be required to pay in the future. These increases in tax basis may also decrease gains (or increase losses) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets.

The Tax Receivable Agreement provides for the payment by us to exchanging holders of Post-Merger indie Units of 85% of the tax benefits, if any, that we realize (or in certain cases are deemed to realize) as a result of these increases in tax basis and certain tax attributes of the ADK Blocker Group (as defined in the MTA) and tax benefits related to entering into the Tax Receivable Agreement, including tax benefits attributable to payments under the Tax Receivable Agreement. This payment obligation is an obligation of us and not of ADK LLC. For purposes of the Tax Receivable Agreement, the cash tax savings in income tax will be computed by comparing our actual income tax liability (calculated with certain assumptions) to the amount of such taxes that we would have been required to pay had there been no increase (or decrease) to the tax basis of the assets of ADK LLC as a result of the exchanges and had we not entered into the Tax Receivable Agreement. Such increase or decrease will be calculated under the Tax Receivable Agreement without regard to any transfers of Post-Merger indie Units or distributions with respect to Post-Merger indie Units before the exchange under the Exchange Agreement.

The term of the Tax Receivable Agreement will continue until all such tax benefits have been utilized or expired unless we exercise our right to terminate the Tax Receivable Agreement for an amount representing the present value of anticipated future tax benefits of the Tax Receivable Agreement is otherwise accelerated (as described in more detail below). Estimating the amount of payments that may be made under the Tax Receivable Agreement is by its nature imprecise, insofar as the calculation of amounts payable depends on a variety of factors. The actual increase in tax basis, as well as the amount and timing of any payments under the Tax Receivable Agreement, will vary depending upon a number of factors, including:

•        the timing of exchanges — for instance, the increase in any tax deductions will vary depending on the fair market value, which may fluctuate over time, of the depreciable or amortizable assets of ADK LLC at the time of each exchange;

•        the price of shares of our Class A common stock at the time of each exchange — the increase in any tax deductions, as well as the tax basis increase in other assets of ADK LLC, is directly proportional to the price of shares of our Class A common stock at the time of each exchange;

•        the extent to which such exchanges are taxable — if an exchange is not taxable for any reason, increased deductions will not be available; and

•        the amount and timing of our income — we will be required to pay 85% of tax benefits as and when realized, under the terms of the Tax Receivable Agreement. Except as discussed below with respect to a material breach of a material obligation under the Tax Receivable Agreement, a change of control, or other circumstances requiring an early termination of the tax receivable agreement, if we do not have taxable income, we generally will not be required to make payments under the Tax Receivable Agreement for that taxable year because no tax benefits will have actually been realized. However, any tax benefits that do not result in realized benefits in a given tax year will likely generate tax attributes that may be utilized to generate benefits in previous or future tax years. The utilization of such tax attributes will result in payments under the Tax Receivables Agreement.

We anticipate that we will account for the effects of these increases in tax basis and associated payments under the Tax Receivable Agreement arising from future exchanges as follows:

•        we will record an increase in deferred tax assets for the estimated income tax effects of the increases in tax basis based on enacted federal and state tax rates at the date of the exchange;

75

•        to the extent we estimate that we will not realize the full benefit represented by the deferred tax asset, based on an analysis that will consider, among other things, our expectation of future earnings, we will reduce the deferred tax asset with a valuation allowance;

•        we will record the estimated realizable tax benefit (which is the recorded deferred tax asset less any recorded valuation allowance) as an increase to the liability due under the Tax Receivable Agreement; and

•        all of the effects of changes in any of our estimates after the date of the exchange will be included in net income. Similarly, the effect of subsequent changes in the enacted tax rates will be included in net income.

We expect that, as a result of the size of the increases in the tax basis of the tangible and intangible assets of ADK LLC, the payments that we may make under the Tax Receivable Agreement will be substantial. There may be a material negative effect on our liquidity if, as a result of timing discrepancies or otherwise, the payments under the Tax Receivable Agreement exceed the actual cash tax savings that we realize in respect of the tax attributes subject to the Tax Receivable Agreement and/or distributions to us by ADK LLC are not sufficient to permit us to make payments under the Tax Receivable Agreement after we have paid taxes. Late payments under the Tax Receivable Agreement generally will accrue interest at an uncapped rate equal to LIBOR plus 500 basis points. The payments under the Tax Receivable Agreement are not conditioned upon continued ownership of us by holders of Post-Merger indie Units. The rights of each party under the Tax Receivable Agreement other than us are assignable.

In addition, the Tax Receivable Agreement provides that, if we materially breach any of our obligations under the Tax Receivable Agreement of if certain mergers, asset sales, other forms of business combination, or other changes of control were to occur, our (or our successor’s) obligations with respect to exchanged or acquired Post-Merger indie Units (whether exchanged or acquired before or after such transaction) would be based on certain assumptions, including that we would have sufficient taxable income to fully utilize the deductions arising from the increased tax deductions and tax basis and other benefits related to entering into the Tax Receivable Agreement.

Furthermore, we may elect to terminate the Tax Receivable Agreement early by making an immediate payment equal to the present value of the anticipated future cash tax savings. In determining such anticipated future cash tax savings, the Tax Receivable Agreement includes several assumptions, including (i) that any Post-Merger indie Units that have not been exchanged are deemed exchanged for the market value of the shares of our Class A common stock at the time of termination, (ii) we will have sufficient taxable income in each future taxable year to fully realize all potential tax savings, (iii) the tax rates for future years will be those specified in the law as in effect at the time of termination and (iv) certain non-amortizable assets are deemed disposed of within specified time periods. In addition, the present value of such anticipated future cash tax savings are discounted at a rate equal to LIBOR plus 100 basis points. If we were to elect to terminate the Tax Receivable Agreement at the current time, we estimate that we would be required to pay approximately $97 million to satisfy our total Tax Receivable Agreement liability.

As a result of the change of control provisions and the early termination right, we could be required to make payments under the Tax Receivable Agreement that are greater than or less than the actual cash tax savings that we realize in respect of the tax attributes subject to the Tax Receivable Agreement. In these situations, our obligations under the Tax Receivable Agreement could have a substantial negative impact on our liquidity.

Decisions made by us in the course of running our business may influence the timing and amount of payments that are received by an exchanging or selling existing owner under the Tax Receivable Agreement. For example, the earlier disposition of assets following an exchange or acquisition transaction generally will accelerate payments under the Tax Receivable Agreement and increase the present value of such payments, and the disposition of assets before an exchange or acquisition transaction will increase an existing owner’s tax liability without giving rise to any rights of an existing owner to receive payments under the Tax Receivable Agreement.

Payments under the Tax Receivable Agreement are based on the tax reporting positions that we will determine. We will not be reimbursed for any payments previously made under the Tax Receivable Agreement if a tax item is successfully challenged by the IRS. As a result, in certain circumstances, payments could be made under the Tax Receivable Agreement in excess of our cash tax savings.

The form of Tax Receivable Agreement is included as an exhibit to the registration statement for which this prospectus forms a part and is incorporated by reference herein.

Amended Operating Agreement

Concurrently with the completion of the Business Combination, the existing amended and restated limited liability company agreement of ADK LLC was further amended and restated in its entirety to become the Amended Operating Agreement. Below is a summary of some of the provisions of the Amended Operating Agreement.

Rights of the Units

The Post-Merger indie Units will be entitled to share in the profits and losses of ADK LLC and to receive distributions as and if declared by the managing member of ADK LLC and will have no voting rights.

Management

The Company, as the manager of ADK LLC, will have the sole vote on all matters that require a vote of members under the Amended Operating Agreement or applicable law. The business, property and affairs of ADK LLC will be managed solely by the manager.

Distributions

The Company, as managing member of ADK LLC may, in its sole discretion, authorize distributions to the ADK LLC members. All such distributions will be made pro rata in accordance with each member’s interest in ADK LLC.

The Amended Operating Agreement provides for cash distributions, which we refer to as “tax distributions,” to the holders of Post-Merger indie Units if we, as the sole manager of ADK LLC, reasonably determine that a holder, by reason of holding Post-Merger indie Units, will incur an income tax liability. Generally, these tax distributions will be computed based on our estimate of the net taxable income of ADK LLC multiplied by an assumed tax rate equal to the highest effective marginal combined United States federal, state and local income tax rate prescribed for a corporate resident in California (taking into account the non-deductibility of certain expenses and the character of our income).

Upon the liquidation or winding up of ADK LLC, all net proceeds thereof will be distributed one hundred percent (100%) to the holders of Post-Merger indie Units, pro rata based on their percentage interests.

Transfer Restrictions

The Amended Operating Agreement will contain restrictions on transfers of units and will require the prior consent of the manager for such transfers, except, in each case, for (i) certain transfers to permitted transferees under certain conditions and (ii) exchanges of Post-Merger indie Units for our Class A common stock pursuant to the Exchange Agreement as described below.

The Amended Operating Agreement is included as an exhibit to the registration statement for which this prospectus forms a part and is incorporated by reference herein.

Sponsor Letter Agreement

Simultaneously with the execution of the MTA, the Sponsor entered into a letter agreement with Thunder Bridge II and ADK LLC (the “Sponsor Letter Agreement”), pursuant to which at the Closing the Sponsor deposited with Continental Stock Transfer and Trust, as escrow agent (the “Sponsor Escrow Agent”), the Sponsor Escrow Shares, along with any earnings or proceeds thereon. At any time subsequent to the Closing, the Sponsor may liquidate pursuant to its organizational documents and distribute the rights to the Escrow Shares among its members in accordance with its operating agreement, subject to the escrow restrictions. Following this dissolution, Gary Simanson, the managing member of the Sponsor, will have the authority to act on behalf of the Sponsor’s members, subject to the escrow agreement, in releasing from escrow or otherwise disposing of the Escrow Shares. While the Escrow Shares are held in escrow, the Sponsor’s members have full ownership rights to the Escrow Shares, including voting rights, but any earnings or proceeds from the Escrow Shares will be retained in the escrow account, and neither the Sponsor’s members nor Mr. Simanson following the Sponsor dissolution will have the right to transfer the Escrow Shares.

77

Release Escrow Shares

Fifty percent of the Escrow Shares will be released from escrow to the Sponsor (along with any related earnings and proceeds) if at any time prior to December 31, 2027 the closing price of shares of our Class A common stock (or any successor equity security) on the principal exchange on which such securities are then listed or quoted will have been at or above $12.50 for 20 trading days over a 30 trading day period (subject to equitable adjustment for stock splits, stock dividends, reorganizations or extra ordinary dividends), and 100% of the remaining Escrow Shares will vest and be released from escrow to the Sponsor (along with any related earnings and proceeds) if at any time prior to December 31, 2027 the closing price of shares of our Class A common stock (or any successor equity security) on the principal exchange on which such securities are then listed or quoted will have been at or above $15.00 for 20 trading days over a 30 trading day period (subject to equitable adjustment for stock splits, stock dividends, reorganizations or extra ordinary dividends).

Additionally, all of the Escrow Shares will vest and be released from escrow to the Sponsor (along with any related earnings and proceeds) if prior to December 31, 2027, (i) we engage in a going private transaction or otherwise ceases to be subject to reporting obligations under Sections 13 or 15(d) of the Exchange Act, (ii) shares of Class A common stock or successor securities cease to be listed on a national securities exchange other than due to a violation of (x) minimum exchange listing requirements (including minimum round lot holder requirements), unless such failure is caused by an action or omission of us with the primary intent to cause, or that would reasonably be expected to cause, the delisting or (y) a minimum price per share requirement or (iii) there is a change of control of us.

In the event that the Escrow Shares (and related escrow property) are not released from escrow prior to December 31, 2027, they will be forfeited to us and cancelled.

Subscription Agreements

On December 14, 2020, Thunder Bridge II entered into Subscription Agreements with PIPE Investors, including Peter Kight, a member of our Board of Directors and an affiliate of the Sponsor, pursuant to which Thunder Bridge II agreed to issue and sell to the PIPE Investors an aggregate of 15,000,000 of Thunder Bridge II Class A ordinary shares, at a price of $10.00 per Class A ordinary share, simultaneously with or immediately prior to the Closing. Upon the Business Combination, the shares issued pursuant to the PIPE Financing were automatically exchanged for 15,000,000shares of our Class A common stock.

Pursuant to the Subscription Agreements, we have agreed that, within 30 calendar days after the Closing, we will file with the SEC (at our sole cost and expense) a registration statement registering the resale of the PIPE Shares, and we shall use our commercially reasonable efforts to have such registration statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) the 90th calendar day (or 120th calendar day if the SEC notifies us that it will “review” the registration statement) following the Closing and (ii) the fifth business day after the date we are notified (orally or in writing, whichever is earlier) by the SEC that the registration statement will not be “reviewed” or will not be subject to further review.

Registration Rights Agreement

On the Closing Date, Surviving Pubco entered into a registration rights agreement, dated as of the Closing Date, with Mr.McClymont, Mr.Aoki, certain other indie Equity Holders, Mr.Schiller and Bison Capital Partners IV, L.P., pursuant to which Surviving Pubco has agreed to register for resale under the Securities Act shares of Class A common stock issued to such parties as consideration in connection with the Business Combination, and to provide such parties with certain rights relating to the registration of the securities held by them.

The foregoing description of the registration rights agreement does not purport to be complete and is qualified in its entirety by the terms and conditions of the registration rights agreement, which is included as an exhibit to the registration statement for which this prospectus forms a part and is incorporated by reference herein.

78

Lock-up Agreements

On the Closing Date, we entered into lock-up agreements, dated as of the Closing Date, with certain indie Equity Holders, including each of our executive officers and directors, pursuant to which such indie Equity Holders agreed not to offer, sell, contract to sell, pledge or otherwise dispose of any shares of Class A common stock received as consideration in connection with the Business Combination, including any Earn Out Shares, for a period of six months from the Closing.

The foregoing description of the lock-up agreements does not purport to be complete and is qualified in its entirety by the terms and conditions of the lock-up agreements, a form of which is included as an exhibit to the registration statement for which this prospectus forms a part and is incorporated by reference herein.

Other Transactions

Simultaneously with the consummation of the Business Combination, the Sponsor converted $1,500,000 principal amount of working capital promissory notes issued to it by Thunder Bridge II warrants to purchase 1,500,000shares of our Class A common stock at pursuant to the terms of such notes. The terms of the sponsor warrants are substantially the same as the private placement warrants.

Statement of Policy Regarding Transactions with Related Persons

We plan to adopt a formal written policy providing that our officers, directors, nominees for election as directors, beneficial owners of more than 5% of any class of our capital stock, any member of the immediate family of any of the foregoing persons and any firm, corporation or other entity in which any of the foregoing persons is employed or is a general partner or principal or in a similar position or in which such person has a 5% or greater beneficial ownership interest, are not permitted to enter into a related person transaction with us without the approval of our nominating and corporate governance committee, subject to certain exceptions approved by our Audit Committee

Indemnification of Directors and Officers

Our Bylaws provide that we will indemnify our directors and officers to the fullest extent permitted by the Delaware General Corporation Law (the “DGCL”). In addition, our Certificate of Incorporation provides that our directors will not be liable for monetary damages for breach of fiduciary duty to the fullest extent permitted by the DGCL. In addition, we have entered into indemnification agreements with each of our directors and executive officers, to provide indemnification and reimbursement of expenses to the fullest extent permitted by law. The Company has entered into indemnification agreements with each of its officers and directors, which provide indemnification and advancement/reimbursement of expenses to the fullest extent permitted by law.

____________

*        Represents less than 1% of the total voting power.

(1)      Holders of Class A common stock are entitled to one vote for each share of Class A common stock held by them. Certain indie Equity Holders own Post-Merger indie Units and a corresponding number of shares of Class V common stock and will be entitled to one vote per share of Class V common stock. Subject to the terms of the Exchange Agreement, the Post-Merger indie Units are initially exchangeable for shares of Class A common stock on a one-for-one basis from and after the six-month anniversary of the Closing. Upon such exchange, the corresponding shares of Class V common stock will be cancelled.

80

(2)      Represents the percentage of voting power of the holders of Class A common stock and Class V common stock of indie voting together as a single class.

(3)      Includes 937,100shares subject to vesting conditions.

(4)      Includes 1,000,000 Class A common shares acquired in the PIPE Financing.

DESCRIPTION OF SECURITIES

The following summary of the material terms of our securities is not intended to be a complete summary of the rights and preferences of such securities, and is qualified by reference to our Amended and Restated Certificate of Incorporation (as amended, the “Certificate of Incorporation”), our Bylaws (the “Bylaws”) and the warrant-related documents described herein, which are exhibits to the registration statement of which this prospectus is a part. We urge to you reach each of the Certificate of Incorporation, Bylaws and the warrant-related documents described herein in their entirety for a complete description of the rights and preferences of our securities.

Authorized and Outstanding Stock

The Certificate of Incorporation authorizes the issuance of 300,000,000shares, consisting of:

•        10,000,000shares of preferred stock, par value $0.0001 per share (“Preferred Stock”); and

•        250,000,000shares of Class A common stock, par value $0.0001 per share, and 40,000,000shares of Class V common stock, par value $0.0001 per share.

Class A Common Stock

As of June30, 2021, we had 101,482,466shares of Class A common stock outstanding. All issued and outstanding shares of Class A common stock are fully paid and non-assessable. In connection with the Business Combination, the sponsor shares held by the Sponsor were converted into shares of our Class A common stock of the Company, of which 3,450,000shares of Class A common stock held by the Sponsor will held in escrow and subject to forfeiture if certain stock price performance thresholds of the Company are not achieved by December31, 2027. See the section entitled “Certain Relationships and Related Person Transactions — Sponsor Letter Agreement.”

Voting rights.    Each holder of Class A common stock is entitled to one vote for each share of Class A common stock held of record by such holder on all matters on which stockholders generally are entitled to vote. The holders of Class A common stock do not have cumulative voting rights in the election of directors. Generally, all matters to be voted on by stockholders must be approved by a majority vote (or, in the case of election of directors, by a plurality) of the votes entitled to be cast by all stockholders present in person or represented by proxy and voting affirmatively or negatively on the matter, voting together as a single class. Notwithstanding the foregoing, to the fullest extent permitted by law, holders of Class A common stock, as such, will have no voting power with respect to, and will not be entitled to vote on, any amendment to the Certificate of Incorporation (including any certificate of designations relating to any series of Preferred Stock) that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to the Certificate of Incorporation (including any certificate of designations relating to any series of Preferred Stock) or pursuant to the DGCL.

Dividend rights.    Subject to preferences that may be applicable to any outstanding Preferred Stock, the holders of shares of Class A common stock are entitled to receive ratably such dividends, if any, as may be declared from time to time by our board of directors out of funds legally available therefor.

Rights upon liquidation.    In the event of any voluntary or involuntary liquidation, dissolution or winding up of our affairs, the holders of Class A common stock are entitled to share ratably in all assets remaining after payment of our debts and other liabilities, subject to prior distribution rights of Preferred Stock or any class or series of stock having a preference over the Class A common stock, then outstanding, if any.

Other rights.    The holders of Class A common stock have no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to the Class A common stock. The rights, preferences and privileges of holders of the Class A common stock will be subject to those of the holders of any shares of the Preferred Stock the Company may issue in the future.

Class V Common Stock

As of June30, 2021, we had 33,827,371shares of Class V common stock outstanding. All outstanding shares of Class V common stock are fully paid and non-assessable.

86

Voting rights.    The holders of the Class V common stock are entitled to one vote for each share of Class V common stock held of record by such holders on all matters on which stockholders generally are entitled to vote. The holders of Class V common stock do not have cumulative voting rights in the election of directors. Holders of shares of Class V common stock will vote together with holders of the Class A common stock as a single class on all matters presented to the Company’s stockholders for their vote or approval. Generally, all matters to be voted on by stockholders must be approved by a majority (or, in the case of election of directors, by a plurality) of the votes entitled to be cast by all stockholders present in person or represented by proxy, voting together as a single class. Notwithstanding the foregoing, to the fullest extent permitted by law, holders of Class V common stock, as such, will have no voting power with respect to, and will not be entitled to vote on, any amendment to the Certificate of Incorporation (including any certificate of designations relating to any series of Preferred Stock) that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to the Certificate of Incorporation (including any certificate of designations relating to any series of Preferred Stock) or pursuant to the DGCL.

Dividend rights.    The holders of the Class V common stock will not participate in any dividends declared by the board of directors.

Rights upon liquidation.    In the event of any voluntary or involuntary liquidation, dissolution or winding up of our affairs, the holders of Class V common stock are not entitled to receive any of our assets.

Other rights.    The holders of shares of Class V common stock do not have preemptive, subscription, redemption or conversion rights. There are no redemption or sinking fund provisions applicable to the Class V common stock.

Issuance and retirement of Class V common stock.    In the event that any outstanding share of Class V common stock ceases to be held directly or indirectly by a holder of a Post-Merger indie Unit, such share will automatically be transferred to us for no consideration and thereupon will be retired. We will not issue additional shares of Class V common stock after the adoption of the Certificate of Incorporation other than in connection with the valid issuance or transfer of Post-Merger indie Units in accordance with our governing documents and those of ADK LLC.

Preferred Stock

As of June30, 2021, no shares of Preferred Stock were issued or outstanding. The Certificate of Incorporation authorizes our board of directors to establish one or more series of Preferred Stock. Unless required by law or any stock exchange, the authorized shares of Preferred Stock will be available for issuance without further action by the holders of the Common Stock. Our board of directors has the discretion to determine the powers, preferences and relative, participating, optional and other special rights, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, of each series of Preferred Stock.

The issuance of Preferred Stock may have the effect of delaying, deferring or preventing a change in control of the Company without further action by the stockholders. Additionally, the issuance of Preferred Stock may adversely affect the holders of our Common Stock by restricting dividends on the Class A common stock, diluting the voting power of the Class A common stock and the Class V common stock or subordinating the liquidation rights of the Class A common stock. As a result of these or other factors, the issuance of Preferred Stock could have an adverse impact on the market price of our Class A common stock. At present, we have no plans to issue any Preferred Stock.

Dividends

It is our present intention to retain any earnings for use in our business operations and, accordingly, we do not anticipate the board of directors declaring any dividends on the shares of Class A common stock in the foreseeable future. The payment of cash dividends in the future will be dependent upon our revenues and earnings, if any, capital requirements and general financial condition. The payment of any cash dividends will be within the discretion of our board of directors.

We are a holding company with no material assets other than our interest in ADK LLC. We intend to cause ADK LLC to make distributions to holders of Post-Merger indie Units in amounts sufficient to cover applicable taxes and other obligations under the Tax Receivable Agreement as well as any cash dividends declared by us.

87

The Amended Operating Agreement provides that pro rata cash distributions be made to holders of Post-Merger indie Units (including us) at certain assumed tax rates, which we refer to as “tax distributions.” See the section entitled “Certain Relationships and Related Person Transactions — Amended Operating Agreement.” We anticipate that amounts we will receive may, in certain periods, exceed our actual tax liabilities and obligations to make payments under the Tax Receivable Agreement. Our board of directors, in its sole discretion, will make any determination from time to time with respect to the use of any such excess cash so accumulated, which may include, among other uses, to acquire additional newly issued Post-Merger indie Units from indie at a per unit price determined by reference to the market value of the Class A common stock; to pay dividends, which may include special dividends, on our Class A common stock; to fund repurchases of Class A common stock; or any combination of the foregoing. We also expect, if necessary, to undertake ameliorative actions, which may include pro rata or non-pro rata reclassifications, combinations, subdivisions or adjustments of outstanding Post-Merger indie Units, to maintain one-for-one parity between Post-Merger indie Units and shares of Class A common stock of the Company. See the risk factor entitled “Risk Factors — Risks Related to Our Organizational Structure — We are a holding company and our only material asset is our interest in ADK LLC, and we are accordingly dependent upon distributions made by our subsidiaries to pay taxes, make payments under the Tax Receivable Agreement and pay dividends.”

Anti-Takeover Effects of the Certificate of Incorporation, the Bylaws and Certain Provisions of Delaware Law

The Certificate of Incorporation, the Bylaws and the DGCL contain provisions, which are summarized in the following paragraphs, which are intended to enhance the likelihood of continuity and stability in the composition of our board of directors and to discourage certain types of transactions that may involve an actual or threatened acquisition of the Company. These provisions are intended to avoid costly takeover battles, reduce our vulnerability to a hostile change of control or other unsolicited acquisition proposal, and enhance the ability of the board of directors to maximize stockholder value in connection with any unsolicited offer to acquire us. However, these provisions may have the effect of delaying, deterring or preventing a merger or acquisition of the Company by means of a tender offer, a proxy contest or other takeover attempt that a stockholder might consider in its best interest, including attempts that might result in a premium over the prevailing market price for the shares of Class A common stock. See also “Risk Factors — Risks Related to Ownership of Our Class A Common Stock and Warrants — Delaware law and our Certificate of Incorporation and Bylaws contain certain provisions, including anti-takeover provisions, that limit the ability of stockholders to take certain actions and could delay or discourage takeover attempts that stockholders may consider favorable.”

Authorized but Unissued Capital Stock

Delaware law does not require stockholder approval for any issuance of authorized shares. However, the listing requirements of Nasdaq, which apply so long as the Class A common stock remains listed on Nasdaq, require stockholder approval of certain issuances equal to or exceeding 20% of the then outstanding voting power or then outstanding number of shares of Class A common stock. Additional shares that may be issued in the future may be used for a variety of corporate purposes, including future public offerings, to raise additional capital or to facilitate acquisitions.

One of the effects of the existence of unissued and unreserved common stock may be to enable the board of directors to issue shares to persons friendly to current management, which issuance could render more difficult or discourage an attempt to obtain control of the Company by means of a merger, tender offer, proxy contest or otherwise and thereby protect the continuity of management and possibly deprive stockholders of opportunities to sell their shares of Class A common stock at prices higher than prevailing market prices.

Election of Directors and Vacancies

The Certificate of Incorporation provides that the board of directors will determine the number of directors who will serve on the board. The exact number of directors will be fixed from time to time by a majority of the board of directors. The board of directors is divided into three classes designated as Class I, Class II and Class III. Class I directors will initially serve for a term expiring at the first annual meeting of stockholders following the closing of the Business Combination. Class II and Class III directors will initially serve for a term expiring at the second and third annual meeting of stockholders following the closing of the Business Combination, respectively. At each succeeding annual meeting of stockholders, directors will be elected for a full term of three years to succeed the directors of the class whose terms expire at such annual meeting of the stockholders. There will be no limit on the number of terms a director may serve on the board of directors.

88

In addition, the Certificate of Incorporation provides that any vacancy on the board of directors, including a vacancy that results from an increase in the number of directors or a vacancy that results from the removal of a director with cause, may be filled only by a majority of the directors then in office, subject to the provisions of any rights of the holders of Preferred Stock.

Notwithstanding the foregoing provisions of this section, each director will serve until his or her successor is duly elected and qualified or until his or her earlier death, resignation or removal. No decrease in the number of directors constituting the board of directors will shorten the term of any incumbent director.

No Cumulative Voting

Under Delaware law, the right to vote cumulatively does not exist unless the certificate of incorporation expressly authorizes cumulative voting. The Certificate of Incorporation does not authorize cumulative voting.

General Stockholder Meetings

The Certificate of Incorporation provides that special meetings of stockholders may be called only by or at the direction of the Chairman of the Board, the Chief Executive Officer or a majority of the total number of directors that the Company would have if there were no vacancies on the board of directors.

Requirements for Advance Notification of Stockholder Meetings, Nominations and Proposals

The Bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of the board of directors or a committee of the board of directors. For any matter to be “properly brought” before a meeting, a stockholder will have to comply with advance notice requirements and provide us with certain information. Generally, to be timely, a stockholder’s notice must be received at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary date of the immediately preceding annual meeting of stockholders. The Bylaws also specify requirements as to the form and content of a stockholder’s notice. The Bylaws allow the presiding officer at a meeting of the stockholders to adopt rules and regulations for the conduct of meetings which may have the effect of precluding the conduct of certain business at a meeting if the rules and regulations are not followed. These provisions may also defer, delay or discourage a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to influence or obtain control of the Company.

Supermajority Provisions

The DGCL provides generally that the affirmative vote of a majority of the outstanding shares entitled to vote thereon, voting together as a single class, is required to amend a corporation’s certificate of incorporation, unless the certificate of incorporation requires a greater percentage. The Certificate of Incorporation provides that the affirmative vote of the holders of at least 66⅔% of our capital stock, voting together as a single class, will be required to amend provisions of the Certificate of Incorporation regarding calling special meetings of stockholders and stockholder action by written consent.

The Bylaws provide that, except as otherwise provided by law or the Certificate of Incorporation, the Bylaws may be amended in any respect or repealed at any time, either (a) at any meeting of stockholders, provided that any amendment or supplement proposed to be acted upon at any such meeting has been properly described or referred to in the notice of such meeting, or (b) by the board of directors, provided that no amendment adopted by the board of directors may vary or conflict with any amendment adopted by the stockholders in accordance with the Certificate of Incorporation and the Bylaws. The Bylaws provide that the following provisions therein may be amended, altered, repealed or rescinded only by the affirmative vote of the holders of at least 66⅔% in voting power of all our outstanding voting capital stock, voting together as a single class:

•        the provisions regarding calling annual and special meetings of stockholders;

•        the provisions regarding the nominations of directors and the proposal of other business at an annual or special meeting of stockholders;

•        the provisions regarding the conduct of stockholder meetings;

89

•        the provisions providing for a classified board of directors (including the election and term of directors);

•        the provisions regarding filling vacancies on the board of directors and newly created directorships;

•        the provisions regarding removal of directors; and

•        the amendment provision requiring that the above provisions be amended only with an 66⅔% supermajority vote.

These provisions may have the effect of deterring hostile takeovers or delaying or preventing changes in control of the Company or its management, such as a merger, reorganization or tender offer. These provisions are intended to enhance the likelihood of continued stability in the composition of the board of directors and its policies and to discourage certain types of transactions that may involve an actual or threatened acquisition of the Company. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. The provisions are also intended to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, may inhibit fluctuations in the market price of our shares that could result from actual or rumored takeover attempts. Such provisions may also have the effect of preventing changes in management.

Exclusive Forum

The Certificate of Incorporation provides that, unless we consent to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, in the event that the Chancery Court does not have jurisdiction, the federal district court for the District of Delaware) will, to the fullest extent permitted by law, be the sole and exclusive forum for (1) any derivative action, suit or proceeding brought on behalf of the Company, (2) any action, suit or proceeding asserting a claim of breach of a fiduciary duty owed by any director, officer, employee or stockholder of the Company to the Company or to the Company’s stockholders, (3) any action, suit or proceeding arising pursuant to any provision of the DGCL or the Bylaws or the Certificate of Incorporation or as to which the DGCL confers jurisdiction on the Chancery Court, or (4) any action, suit or proceeding asserting a claim against the Company governed by the internal affairs doctrine. Our Certificate of Incorporation also provides that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States of America will be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. Notwithstanding the foregoing, the inclusion of such provision in our Certificate of Incorporation will not be deemed to be a waiver by our stockholders of our obligation to comply with federal securities laws, rules and regulations, and the provisions of this paragraph will not apply to suits brought to enforce any liability or duty created by the Exchange Act or any other claim for which the federal district courts of the United States of America shall be the sole and exclusive forum. Although we believe the Exclusive Forum Provision benefits us by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against our directors and officers. Furthermore, the enforceability of choice of forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that a court could find these types of provisions to be inapplicable or unenforceable.

Limitations on Liability and Indemnification of Officers and Directors

The DGCL authorizes corporations to limit or eliminate the personal liability of directors to corporations and their stockholders for monetary damages for breaches of directors’ fiduciary duties, subject to certain exceptions. The Certificate of Incorporation includes a provision that eliminates the personal liability of directors for monetary damages for any breach of fiduciary duty or other act or omission as a director of the Company, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL. The effect of these provisions is to eliminate the rights of the Company and its stockholders, through stockholders’ derivative suits on the Company’s behalf, to recover monetary damages from a director for breach of fiduciary duty as a director, including breaches resulting from grossly negligent behavior. However, exculpation does not apply to any director if the director has breached his or her duty of loyalty to the Company or its stockholder or for any act not in good faith or which involve intentional misconduct or a knowing violation of law.

The Certificate of Incorporation provides that we must indemnify and advance expenses to directors and officers to the fullest extent authorized by the DGCL. We are also expressly authorized to carry directors’ and officers’ liability insurance providing indemnification for directors, officers and certain employees for some liabilities. The limitation of

90

liability, indemnification and advancement provisions in the Certificate of Incorporation may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our stockholders. In addition, your investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions. We believe that these provisions, liability insurance and the indemnity agreements are necessary to attract and retain talented and experienced directors and officers.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

There is currently no pending material litigation or proceeding involving any of our respective directors, officers or employees for which indemnification is sought.

Warrants

As of June10, 2021, 27,400,000 warrants were outstanding, including 17,250,000 public warrants, 8,650,000 private placement warrants and 1,500,000 sponsor warrants. Each whole public warrant entitles the registered holder to purchase one share of Class A common stock at a price of $11.50 per share, subject to adjustment as discussed below, at any time commencing upon the later of 12months from the closing of the IPO or 30 days after the completion of the Business Combination. Pursuant to the warrant agreement, as amended by the assignment, assumption and amendment agreement entered into in connection with the Business Combination, the Warrant Agreement, a public warrant holder may exercise its warrants only for a whole number of shares. This means that only a whole number of warrants may be exercised at any given time by a public warrant holder. However, except as set forth below, no public warrants will be exercisable for cash unless we have an effective and current registration statement covering the shares of Class A common stock issuable upon exercise of the warrants and a current prospectus relating to such shares of common stock. Notwithstanding the foregoing, if a registration statement covering the shares of Class A common stock issuable upon exercise of the public warrants is not effective within 60 business days from the completion of the Business Combination, public warrant holders may, until such time as there is an effective registration statement and during any period when we will have failed to maintain an effective registration statement, exercise warrants on a cashless basis pursuant to an available exemption from registration under the Securities Act. If an exemption from registration is not available, holders will not be able to exercise their warrants on a cashless basis. The public warrants will expire at 5:00 p.m., New York City time on the earlier to occur of: (i) five years from the completion of the Business Combination or (ii) the redemption date as fixed by us pursuant to the Warrant Agreement, if we elect to redeem all warrants.

The private placement warrants and sponsor warrants are identical to the public warrants except that the private placement warrants and sponsor warrants (including the shares of Class A common stock issuable upon exercise of the private placement warrants and sponsor warrants) will (i) not be transferable, assignable or salable until 30 days after the completion of the Business Combination, (ii) be exercisable for cash (even if a registration statement covering the Class A common stock issuable upon exercise of such warrants is not effective) or on a cashless basis, at the holder’s option, and (iii) not be redeemable by us, in each case so long as they are still held by the initial purchasers or their respective affiliates.

We may call the warrants for redemption (excluding the private placement warrants and sponsor warrants), in whole and not in part, at a price of $0.01 per warrant:

•        at any time while the warrants are exercisable,

•        upon not less than 30 days’ prior written notice of redemption to each public warrant holder,

•        if and only if, the reported last sale price of the shares of our Class A common stock equals or exceeds $18.00 per share, for any 20 trading days within a 30-day trading period ending on the third business day prior to the notice of redemption to public warrant holders, and

•        if and only if, there is a current registration statement in effect with respect to the shares of Class A common stock underlying such warrants at the redemption date and for the entire 30-day trading period referred to above and continuing each day thereafter until the date of redemption.

91

The right to exercise will be forfeited unless the warrants are exercised prior to the date specified in the notice of redemption. On and after the redemption date, a record holder of a warrant will have no further rights except to receive the redemption price for such holder’s warrant upon surrender of such warrant.

The redemption criteria for the warrants have been established at a price which is intended to provide public warrant holders a reasonable premium to the initial exercise price and provide a sufficient differential between the then-prevailing share price and the warrant exercise price so that if the share price declines as a result of a redemption call, the redemption will not cause the share price to drop below the exercise price of the warrants.

If we call the warrants for redemption as described above, our management will have the option to require all holders that wish to exercise warrants to do so on a “cashless basis.” In such event, each holder would pay the exercise price by surrendering the warrants for that number of shares of Class A common stock equal to the quotient obtained by dividing (x) the product of the number of shares underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” will mean the average reported last sale price of the Class A common stock for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants. Whether we will exercise our option to require all holders to exercise their warrants on a “cashless basis” will depend on a variety of factors including the price of the Class A common stock at the time the warrants are called for redemption, our cash needs at such time and concerns regarding dilutive share issuances.

The warrants are issued under a Warrant Agreement, as amended, between us and Continental Stock Transfer & Trust Company, as warrant agent. The Warrant Agreement provides that the terms of the warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval, by written consent or vote, of the holders of a majority of the then outstanding public warrants in order to make any change that adversely affects the interests of the registered holders.

The exercise price and number of shares of Class A common stock issuable on exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, stock split or our recapitalization, reorganization, merger or consolidation. However, the warrants will not be adjusted for issuances of shares of Class A common stock at a price below their respective exercise prices. We are also permitted, in our sole discretion, to lower the exercise price (but not below the par value of a shares of Class A common stock) at any time prior to the expiration date for a period of not less than 10 business days; provided, however, that we provide at least 10 business days’ prior written notice of such reduction to registered holders of the warrants and that any such reduction will be applied consistently to all of the warrants. Any such reduction in the exercise price will comply with any applicable regulations under the federal securities laws, including Rule 13e-4 under the Exchange Act generally and Rule 13e-4(f)(1)(i) specifically.

The warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price, by certified or official bank check payable to us, for the number of warrants being exercised. The public warrant holder will not have the rights or privileges of holders of shares of Class A common stock and any voting rights until they exercise their warrants and receive shares of Class A common stock. After the issuance of Class A common stock upon exercise of the warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

Except as described above, no public warrants will be exercisable and we will not be obligated to issue shares of Class A common stock unless at the time a holder seeks to exercise such warrant, a prospectus relating to the Class A common stock issuable upon exercise of the warrants is current and the Class A common stock has been registered or qualified or deemed to be exempt under the securities laws of the state of residence of the holder of the warrants. Under the terms of the Warrant Agreement, we have agreed to use our best efforts to meet these conditions and to maintain a current prospectus relating to the Class A common stock issuable upon exercise of the warrants until the expiration of the warrants. However, we cannot assure you that we will be able to do so and, if we do not maintain a current prospectus relating to the Class A common stock issuable upon exercise of the warrants, holders will be unable to exercise their warrants and we will not be required to settle any such warrant. If the prospectus relating to the shares of Class A common stock issuable upon the exercise of the warrants is not current or if the Class A common stock is not qualified or exempt from qualification in the jurisdictions in which the holders of the warrants reside, we will not be required to net cash settle or cash settle the warrant exercise, the warrants may have no value, the market for the warrants may be limited and the warrants may expire worthless.

92

Public warrant holders may elect, at their sole option and discretion, to be subject to a restriction on the exercise of their warrants such that an electing public warrant holder (and his, her or its affiliates) would not be able to exercise their warrants to the extent that, after giving effect to such exercise, such holder (and his, her or its affiliates) would beneficially own in excess of 9.8% of the Class A common stock outstanding. Notwithstanding the foregoing, any person who acquires a warrant with the purpose or effect of changing or influencing the control of the Company, or in connection with or as a participant in any transaction having such purpose or effect, immediately upon such acquisition will be deemed to be the beneficial owner of the underlying shares of Class A common stock and not be able to take advantage of this provision.

No fractional shares will be issued upon exercise of the warrants. If, upon exercise of the warrants, a holder would be entitled to receive a fractional interest in a share (as a result of a subsequent stock dividend payable in shares of common stock, or by a split of the Class A common stock or other similar event), we will, upon exercise, round up or down to the nearest whole number the number of shares of Class A common stock to be issued to the public warrant holder.

Contractual Arrangements with respect to Certain Warrants

We have agreed that so long as the private placement warrants and sponsor warrants are still held by the initial purchasers or their affiliates, we will not redeem such warrants, we will allow the holders to exercise such warrants on a cashless basis and such warrants may be exercisable for cash.

Our Transfer Agent and Warrant Agent

The transfer agent for our Class A common stock and warrant agent for our warrants is Continental Stock Transfer & Trust Company. We have agreed to indemnify Continental Stock Transfer & Trust Company in its roles as transfer agent and warrant agent, its agents and each of its shareholders, directors, officers and employees against all liabilities, including judgments, costs and reasonable counsel fees that may arise out of acts performed or omitted for its activities in that capacity, except for any liability due to any gross negligence, willful misconduct or bad faith of the indemnified person or entity.

Rule 144

Rule 144 is not available for the resale of securities initially issued by shell companies (other than business combination related shell companies) or issuers that have been at any time previously a shell company, such as us. However, Rule 144 also includes an important exception to this prohibition if the following conditions are met:

•        the issuer of the securities that was formerly a shell company has ceased to be a shell company;

•        the issuer of the securities is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act;

•        the issuer of the securities has filed all Exchange Act reports and material required to be filed, as applicable, during the preceding 12months (or such shorter period that the issuer was required to file such reports and materials), other than Form 8-K reports; and

•        at least one year has elapsed from the time that the issuer filed current Form 10 type information with the SEC reflecting its status as an entity that is not a shell company.

Upon the closing of the Business Combination, we ceased to be a shell company. As a result, the Selling Securityholders will be able to sell their shares of Class A common stock and private placement warrants and sponsor warrants, as applicable, pursuant to Rule 144 without registration one year from the Closing so long as the other conditions set forth in the exceptions listed above and the other conditions of Rule 144 described below are satisfied.

When and if Rule 144 becomes available for the resale of our securities, a person who has beneficially owned restricted shares of our Class A common stock or warrants for at least six months would be entitled to sell their securities, provided that (i) such person is not deemed to have been one of our affiliates at the time of, or at any time during the three months preceding, a sale, and (ii) we are subject to the Exchange Act periodic reporting requirements for at least three months before the sale and have filed all required reports under Section 13 or 15(d) of the Exchange Act during the 12months (or such shorter period as we were required to file reports) preceding the sale.

93

Persons who have beneficially owned restricted shares of our Class A common stock or warrants for at least six months but who are our affiliates at the time of, or at any time during the three months preceding, a sale, would be subject to additional restrictions, by which such person would be entitled to sell within any three-month period only a number of securities that does not exceed the greater of:

•        one percent (1%) of the total number of shares of common stock then outstanding; or

•        the average weekly reported trading volume of the Class A common stock during the four calendar weeks preceding the filing of a notice on Form 144 with respect to the sale.

Sales by our affiliates under Rule 144 will also be limited by manner of sale provisions and notice requirements and to the availability of current public information about us.

PLAN OF DISTRIBUTION

We are registering the issuance by us of up to 27,400,000shares of Class A common stock, which consists of (i) up to 17,250,000shares of Class A common stock that are issuable upon the exercise of the public warrants, (ii) up to 8,650,000shares of Class A common stock that are issuable upon the exercise of the private placement warrants, and (iii) up to 1,500,000shares of Class A common stock that are issuable upon the exercise of the sponsor warrants. We are also registering for resale by the Selling Securityholders from time to time of (i) up to 70,846,446shares of Class A common stock, comprised of (a) 8,625,000 sponsor shares, (b) 37,071,446shares of Class A common stock issuable upon the exchange of an equal number of LLC Units, and (c) 15,000,000shares of Class A common stock issued in the PIPE Financing, and up to 10,150,000shares of Class A common stock that are issuable upon the exercise of the private placement warrants and sponsor warrants by the holders thereof.

We will not receive any proceeds from the sale of shares of Class A common stock by the Selling Securityholders. We will receive proceeds from the exercise of the warrants, assuming the exercise in full of all of the warrants for cash. The aggregate proceeds to the Selling Securityholders will be the purchase price of the securities less any discounts and commissions borne by the Selling Securityholders.

The Selling Securityholders will pay any underwriting discounts and commissions and expenses incurred by the Selling Securityholders for brokerage, accounting, tax or legal services or any other expenses incurred by the Selling Securityholders in disposing of the securities. We are required to pay all other fees and expenses incident to the registration of the shares of our Class A common stock to be offered and sold pursuant to this prospectus.

The shares of Class A common stock, the private placement warrants and the sponsor warrants beneficially owned by the Selling Securityholders covered by this prospectus may be offered and sold from time to time by the Selling Securityholders. The term “Selling Securityholders” includes donees, pledgees, transferees or other successors in interest selling securities received after the date of this prospectus from a Selling Securityholder as a gift, pledge, partnership distribution or other transfer.

The Selling Securityholders will act independently of us in making decisions with respect to the timing, manner and size of each sale. Such sales may be made on one or more exchanges or in the over-the-counter market or otherwise, at prices and under terms then prevailing or at prices related to the then current market price or in negotiated transactions. Each Selling Securityholder reserves the right to accept and, together with its respective agents, to reject, any proposed purchase of securities to be made directly or through agents. The Selling Securityholders and any of their permitted transferees may sell their securities offered by this prospectus on any stock exchange, market or trading facility on which the securities are traded or in private transactions. If underwriters are used in the sale, such underwriters will acquire the shares for their own account. These sales may be at a fixed price or varying prices, which may be changed, or at market prices prevailing at the time of sale, at prices relating to prevailing market prices or at negotiated prices. The securities may be offered to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. The obligations of the underwriters to purchase the securities will be subject to certain conditions.

The Selling Securityholders may sell their shares and warrants by one or more of, or a combination of, the following methods:

•        purchases by a broker-dealer as principal and resale by such broker-dealer for its own account pursuant to this prospectus;

•        ordinary brokerage transactions and transactions in which the broker solicits purchasers;

•        block trades in which the broker-dealer so engaged will attempt to sell the offered securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•        an over-the-counter distribution in accordance with the rules of Nasdaq;

•        through trading plans entered into by a Selling Securityholder pursuant to Rule 10b5-1 under the Exchange Act, that are in place at the time of an offering pursuant to this prospectus and any applicable prospectus supplement hereto that provide for periodic sales of their securities on the basis of parameters described in such trading plans;

95

•        through the distribution of the securities by any Selling Securityholder to its partners, members or stockholders

•        through one or more underwritten offerings on a firm commitment or best efforts basis;

•        settlement of short sales entered into after the effective date the registration statement of which this prospectus is a part;

•        agreements with broker-dealers to sell a specified number of the securities at a stipulated price per share or warrant;

•        in “at the market” offerings, as defined in Rule 415 under the Securities Act, at negotiated prices, at prices prevailing at the time of sale or at prices related to such prevailing market prices, including sales made directly on a national securities exchange or sales made through a market maker other than on an exchange or other similar offerings through sales agents;

•        in privately negotiated transactions;

•        in options transactions;

•        through a combination of any of the above methods of sale; or

•        any other method permitted pursuant to applicable law.

There can be no assurance that the Selling Securityholders will sell all or any of the securities offered by this prospectus. In addition, any shares that qualify for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this prospectus. The Selling Securityholders have the sole and absolute discretion not to accept any purchase offer or make any sale of securities if they deem the purchase price to be unsatisfactory at any particular time.

Subject to the terms of the agreement(s) governing the registration rights applicable to a Selling Securityholder’s shares of Class A common stock, such Selling Securityholder may transfer shares of Class A common stock to one or more “permitted transferees” in accordance with such agreements and, if so transferred, such permitted transferee(s) will be the selling beneficial owner(s) for purposes of this prospectus. Upon being notified by a Selling Securityholder that it intends to sell our securities, we will, to the extent required, promptly file a supplement to this prospectus to name specifically such person as a Selling Securityholder.

With respect to a particular offering of the securities held by the Selling Securityholders, to the extent required, an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement of which this prospectus is part, will be prepared and will set forth, to the extent required. the following information:

•        the specific securities to be offered and sold;

•        the names of the Selling Securityholders;

•        the respective purchase prices and public offering prices, the proceeds to be received from the sale, if any, and other material terms of the offering;

•        settlement of short sales entered into after the date of this prospectus;

•        the names of any participating agents, broker-dealers or underwriters, if not already named herein; and

•        any applicable commissions, discounts, concessions and other items constituting compensation from the Selling Securityholders.

In connection with distributions of the shares or otherwise, the Selling Securityholders may enter into hedging transactions with broker-dealers or other financial institutions. In connection with such transactions, broker-dealers or other financial institutions may engage in short sales of shares of Class A common stock in the course of hedging transactions, broker-dealers or other financial institutions may engage in short sales of shares of Class A common stock in the course of hedging the positions they assume with Selling Securityholders. The Selling Securityholders may also sell shares of Class A common stock short and redeliver the shares to close out such short positions. The Selling Securityholders may also enter into option or other transactions with broker-dealers or other financial institutions which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus,

96

which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction). The Selling Securityholders may also pledge shares to a broker-dealer or other financial institution, and, upon a default, such broker-dealer or other financial institution, may effect sales of the pledged shares pursuant to this prospectus (as supplemented or amended to reflect such transaction).

In order to facilitate the offering of the securities offered by this prospectus, any underwriters or agents, as the case may be, involved in the offering of such securities may engage in transactions that stabilize, maintain or otherwise affect the price of our securities. Specifically, the underwriters or agents, as the case may be, may over-allot in connection with the offering, creating a short position in our securities for their own account. In addition, to cover overallotments or to stabilize the price of our securities, the underwriters or agents, as the case may be, may bid for, and purchase, such securities in the open market. Finally, in any offering of securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allotted to an underwriter or a broker-dealer for distributing such securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. The underwriters or agents, as the case may be, are not required to engage in these activities, and may end any of these activities at any time.

The Selling Securityholders may solicit offers to purchase the securities directly from, and may sell such securities directly to, institutional investors or others. In this case, no underwriters or agents would be involved. The terms of any of those sales, including the terms of any bidding or auction process, if utilized, will be described in the applicable prospectus supplement.

It is possible that one or more underwriters may make a market in our securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot give any assurance as to the liquidity of the trading market for our securities. Our shares of Class A common stock and warrants are currently listed on Nasdaq under the symbols “INDI” and “INDIW,” respectively.

The Selling Securityholders may authorize underwriters, broker-dealers or agents to solicit offers by certain purchasers to purchase the securities at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth any commissions we or the Selling Securityholders pay for solicitation of these contracts.

A Selling Securityholder may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by any Selling Securityholder or borrowed from any Selling Securityholder or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from any Selling Securityholder in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement (or a post-effective amendment). In addition, any Selling Securityholder may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

In effecting sales, broker-dealers or agents engaged by the Selling Securityholders may arrange for other broker-dealers to participate. Broker-dealers or agents may receive commissions, discounts or concessions from the Selling Securityholders in amounts to be negotiated immediately prior to the sale.

If at the time of any offering made under this prospectus a member of FINRA participating in the offering has a “conflict of interest” as defined in FINRA Rule 5121 (“Rule 5121”), that offering will be conducted in accordance with the relevant provisions of Rule 5121.

To our knowledge, there are currently no plans, arrangements or understandings between the Selling Securityholders and any broker-dealer or agent regarding the sale of the securities by the Selling Securityholders. Upon our notification by a Selling Securityholder that any material arrangement has been entered into with an underwriter or broker-dealer for the sale of securities through a block trade, special offering, exchange distribution, secondary

97

distribution or a purchase by an underwriter or broker-dealer, we will file, if required by applicable law or regulation, a supplement to this prospectus pursuant to Rule 424(b) under the Securities Act disclosing certain material information relating to such underwriter or broker-dealer and such offering.

Underwriters, broker-dealers or agents may facilitate the marketing of an offering online directly or through one of their affiliates. In those cases, prospective investors may view offering terms and a prospectus online and, depending upon the particular underwriter, broker-dealer or agent, place orders online or through their financial advisors.

In offering the shares covered by this prospectus, the Selling Securityholders and any broker-dealers who execute sales for the Selling Securityholders may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. Any discounts, commissions, concessions or profit they earn on any resale of those securities may be underwriting discounts and commissions under the Securities Act.

In order to comply with the securities laws of certain states, if applicable, the shares must be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states the shares may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

We have advised the Selling Securityholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the Selling Securityholders and their affiliates. In addition, we will make copies of this prospectus available to the Selling Securityholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The Selling Securityholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.

A holder of warrants may exercise its warrants in accordance with the Warrant Agreement on or before the expiration date set forth therein by surrendering, at the office of the warrant agent, Continental Stock Transfer & Trust Company, the certificate evidencing such warrant, with the form of election to purchase set forth thereon, properly completed and duly executed, accompanied by full payment of the exercise price and any and all applicable taxes due in connection with the exercise of the warrant, subject to any applicable provisions relating to cashless exercises in accordance with the Warrant Agreement.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of certain United States federal income tax consequences of the ownership and disposition of our Class A common stock. This summary deals only with Class A common stock that is held as a capital asset by a non-U.S. holder (as defined below).

A “non-U.S. holder” means a beneficial owner of our Class A common stock (other than an entity or arrangement treated as a partnership for United States federal income tax purposes) that is not, for United States federal income tax purposes, any of the following:

•        an individual citizen or resident of the United States;

•        a corporation (or any other entity treated as a corporation for United States federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

•        an estate the income of which is subject to United States federal income taxation regardless of its source; or

•        a trust if it (1) is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust or (2) has a valid election in effect under applicable United States Treasury regulations to be treated as a United States person.

This summary is based upon provisions of the Code, and regulations, rulings and judicial decisions as of the date hereof. Those authorities may be changed, perhaps retroactively, so as to result in United States federal income tax consequences different from those summarized below. This summary does not address all of the United States federal income tax consequences that may be relevant to you in light of your particular circumstances, nor does it address the Medicare tax on net investment income, United States federal estate and gift taxes or the effects of any state, local or non-United States tax laws. In addition, it does not represent a detailed description of the United States federal income tax consequences applicable to you if you are subject to special treatment under the United States federal income tax laws (including if you are a United States expatriate, foreign pension fund, “controlled foreign corporation,” “passive foreign investment company” or a partnership or other pass-through entity for United States federal income tax purposes). We cannot assure you that a change in law will not alter significantly the tax considerations that we describe in this summary.

If a partnership (or other entity or arrangement treated as a partnership for United States federal income tax purposes) holds our Class A common stock, the tax treatment of a partner generally will depend upon the status of the partner and the activities of the partnership. If you are a partnership or a partner of a partnership considering an investment in our Class A common stock, you should consult your tax advisors.

If you are considering the purchase of our Class A common stock, you should consult your own tax advisors concerning the particular United States federal income tax consequences to you of the ownership and disposition of our Class A common stock, as well as the consequences to you arising under other United States federal tax laws and the laws of any other taxing jurisdiction.

Dividends

In the event that we make a distribution of cash or other property (other than certain pro rata distributions of our stock) in respect of our Class A common stock, the distribution generally will be treated as a dividend for United States federal income tax purposes to the extent it is paid from our current or accumulated earnings and profits, as determined under United States federal income tax principles. Any portion of a distribution that exceeds our current and accumulated earnings and profits generally will be treated first as a tax-free return of capital, causing a reduction in the adjusted tax basis of a non-U.S. holder’s Class A common stock, and to the extent the amount of the distribution exceeds a non-U.S. holder’s adjusted tax basis in our Class A common stock, the excess will be treated as gain from the disposition of our Class A common stock (the tax treatment of which is discussed below under “— Gainon Disposition of Class A Common Stock”).

99

Dividends paid to a non-U.S. holder generally will be subject to withholding of United States federal income tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. However, dividends that are effectively connected with the conduct of a trade or business by the non-U.S. holder within the United States (and, if required by an applicable income tax treaty, are attributable to a United States permanent establishment) are not subject to the withholding tax, provided certain certification and disclosure requirements are satisfied. Instead, such dividends are subject to United States federal income tax on a net income basis generally in the same manner as if the non-U.S. holder were a United States person as defined under the Code. Any such effectively connected dividends received by a foreign corporation may be subject to an additional “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.

A non-U.S. holder who wishes to claim the benefit of an applicable treaty rate and avoid backup withholding, as discussed below, for dividends will be required (a) to provide the applicable withholding agent with a properly executed Internal Revenue Service (“IRS”) Form W-BEN or Form W-8BEN-E (or other applicable form) certifying under penalty of perjury that such holder is not a United States person as defined under the Code and is eligible for treaty benefits or (b) if our Class A common stock is held through certain foreign intermediaries, to satisfy the relevant certification requirements of applicable United States Treasury regulations. Special certification and other requirements apply to certain non-U.S. holders that are pass-through entities rather than corporations or individuals.

A non-U.S. holder eligible for a reduced rate of United States federal withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

Gain on Disposition of Class A Common Stock

Subject to the discussion of backup withholding below, any gain realized by a non-U.S. holder on the sale or other disposition of our Class A common stock generally will not be subject to United States federal income tax unless:

•        the gain is effectively connected with a trade or business of the non-U.S. holder in the United States (and, if required by an applicable income tax treaty, is attributable to a United States permanent establishment of the non-U.S. holder);

•        the non-U.S. holder is an individual who is present in the United States for 183 days or more in the taxable year of that disposition, and certain other conditions are met; or

•        we are or have been a “United States real property holding corporation” for United States federal income tax purposes and certain other conditions are met.

A non-U.S. holder described in the first bullet point immediately above will be subject to tax on the gain derived from the sale or other disposition in the same manner as if the non-U.S. holder were a United States person as defined under the Code. In addition, if any non-U.S. holder described in the first bullet point immediately above is a foreign corporation, the gain realized by such non-U.S. holder may be subject to an additional “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. An individual non-U.S. holder described in the second bullet point immediately above will be subject to a 30% (or such lower rate as may be specified by an applicable income tax treaty) tax on the gain derived from the sale or other disposition, which gain may be offset by United States source capital losses even though the individual is not considered a resident of the United States.

Generally, a corporation is a “United States real property holding corporation” if the fair market value of its United States real property interests equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests and its other assets used or held for use in a trade or business (all as determined for United States federal income tax purposes). We believe we are not and do not anticipate becoming a “United States real property holding corporation” for United States federal income tax purposes.

Information Reporting and Backup Withholding

Distributions paid to a non-U.S. holder and the amount of any tax withheld with respect to such distributions generally will be reported to the IRS. Copies of the information returns reporting such distributions and any withholding may also be made available to the tax authorities in the country in which the non-U.S. holder resides under the provisions of an applicable income tax treaty.

100

A non-U.S. holder will not be subject to backup withholding on distributions received if such holder certifies under penalty of perjury that it is a non-U.S. holder (and the payor does not have actual knowledge or reason to know that such holder is a United States person as defined under the Code), or such holder otherwise establishes an exemption.

Information reporting and, depending on the circumstances, backup withholding will apply to the proceeds of a sale or other disposition of our Class A common stock within the United States or conducted through certain United States-related financial intermediaries, unless the beneficial owner certifies under penalty of perjury that it is a non-U.S. holder (and the payor does not have actual knowledge or reason to know that the beneficial owner is a United States person as defined under the Code), or such owner otherwise establishes an exemption.

Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a non-U.S. holder’s United States federal income tax liability provided the required information is timely furnished to the IRS.

Additional Withholding Requirements

Under Sections 1471 through 1474 of the Code (such Sections commonly referred to as “FATCA”), a 30% United States federal withholding tax may apply to any dividends paid on our Class A common stock to (i) a “foreign financial institution” (as specifically defined in the Code and whether such foreign financial institution is the beneficial owner or an intermediary) which does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (x) an exemption from FATCA, or (y) its compliance (or deemed compliance) with FATCA (which may alternatively be in the form of compliance with an intergovernmental agreement with the United States) in a manner which avoids withholding, or (ii) a “non-financial foreign entity” (as specifically defined in the Code and whether such non-financial foreign entity is the beneficial owner of an intermediary) which does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (x) an exemption from FATCA, or (y) adequate information regarding certain substantial United States beneficial owners of such entity (if any). If a dividend payment is both subject to withholding under FATCA and subject to the withholding tax discussed above under “— Dividends,” an applicable withholding agent may credit the withholding under FATCA against, and therefore reduce, such other withholding tax. While withholding under FATCA would also have applied to payments of gross proceeds from the sale or other taxable disposition of our Class A common stock, proposed United States Treasury regulations (upon which taxpayers may rely until final regulations are issued) eliminate FATCA withholding on payments of gross proceeds entirely. You should consult your own tax advisors regarding these requirements and whether they may be relevant to your ownership and disposition of our Class A common stock.

101

1.     Nature of the Business and Basis of Presentation

Ay Dee Kay, LLC, d/b/a indie Semiconductor, and Subsidiaries (“indie” or the “Company”) offers highly innovative automotive semiconductors and software solutions for Advanced Driver Assistance Systems (ADAS), including light detection and ranging (“LiDAR”), connected car, user experience and electrification applications. 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 we 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, Boston, Massachusetts, Detroit, Michigan, San Francisco and San Jose, California, Dresden, Germany, Edinburgh, Scotland, and various locations in China. The Company engages subcontractors to manufacture its products. The majority of these subcontractors are located in Asia.

Risks and Uncertainties

In December 2019, COVID-19 was first reported to the World Health Organization (“WHO”), and in January 2020, the WHO declared the outbreak to be a public health emergency. In March 2020, the WHO characterized COVID-19 as a pandemic. Since then, the COVID-19 pandemic (the “Pandemic”) and efforts to control its spread have significantly curtailed the movement of people, goods, and services worldwide. The duration and extent of the Pandemic depends on future developments that cannot be accurately predicted at this time, such as the extent and effectiveness of containment and mitigation actions. It has already had an adverse effect on the global economy, and the ultimate societal and economic impact of the Pandemic remains unknown.

The Company experienced a decrease in customer demand and product shipments in the second quarter of fiscal year 2020. This decrease was primarily the result of closures or reduced capacity at customer manufacturing facilities in China. During the second half of fiscal year 2020, customer manufacturing facilities re-opened and demand increased. The Company has transitioned to a remote work environment for its employees and starting the second fiscal quarter of 2020 to date and reduced discretionary spending. As customer demand increased during the second half of fiscal year 2020 and the first quarter of 2021, the semiconductor industry, and automotive semiconductors in particular, experienced material shortages and supply constraints. Given the Company’s reliance on third-party manufacturing suppliers, these industry dynamics have resulted in certain instances of extended production lead times, increased production and expedite costs, and delays in meeting increasing customer demand for its products, which if unabated, present a significant risk to the Company. In certain circumstances, the Company has increased order lead times, and placed purchase orders with suppliers based on its anticipated demand requirements for the balance of 2021 in efforts to secure production capacity allocation. However, the Company cannot predict the duration or magnitude of the Pandemic or the full impact that it may have on the Company’s financial condition, operations, and workforce. The Company will continue to actively monitor the rapidly evolving situation related to the Pandemic and may take further actions that alter the Company’s operations, including those that may be required by federal, state or local authorities, or that the Company determines are in the best interests of its employees and other third parties with whom the Company does business.

Recent Accounting Pronouncements

Recently Issued Accounting Pronouncements Not Yet Adopted

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”), whereby lessees will be required to recognize for all leases at the commencement date a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. A modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the condensed consolidated financial statements must be applied. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. The FASB issued ASU 2019-10-Financial Instruments-Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates in November 2019 and ASU 2020-05-Revenue from Contracts with Customers (Topic 606) and Leases (Topic 842): Effective Dates for Certain Entities in June 2020. The ASUs change some effective dates for ASU 2016-02 on leasing. After applying ASU 2019-10 and 2020-05, ASU 2016-02 is effective for annual periods beginning after December15, 2021, and interim periods within fiscal years beginning after December15, 2022. The adoption of the new standard is expected to result in the recognition of additional lease liabilities and right-of-use assets as of January1, 2022. The Company is currently evaluating the impact of the new standard on the Company’s condensed consolidated financial statements and related disclosures.

In June 2016, the FASB amended guidance related to impairment of financial instruments as part of ASU 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaces the incurred loss impairment methodology with an expected credit loss model for which a company recognizes an allowance based on the estimate of expected credit loss. This ASU requires entities to measure the impairment of certain financial instruments, including accounts receivable, based on expected losses rather than incurred losses. For non-public business entities, this ASU is effective for fiscal years beginning after December15, 2022, with early adoption permitted, and will be effective for the Company beginning in 2023. The Company is currently evaluating the impact of the new standard on the Company’s condensed consolidated financial statements and related disclosures.

1.     Nature of the Business and Basis of Presentation (cont.)

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) — Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles of ASC 740, Income Taxes. The amendments also improve consistent application of and simplify GAAP for other areas of ASC 740 by clarifying and amending existing guidance. ASU 2019-12 is effective for fiscal years beginning after December15, 2020 (and December15, 2021 for nonpublic companies) and early adoption is permitted. Depending on the amendment, adoption may be applied on a retrospective, modified retrospective, or prospective basis. The Company is currently assessing the impact that this standard will have on its condensed consolidated financial statements and related disclosures.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848), which provides optional expedients and exceptions to contract modifications and hedging relationships that reference the London Interbank Offered Rate or another reference rate expected to be discontinued. The standard is effective upon issuance through December31, 2022 and may be applied at the beginning of the interim period that includes March12, 2020 or any date thereafter. However, ASU 2020-04 will only be available for a limited time (generally through December31, 2022). The Company is currently evaluating the impact of the reference rate reform and ASU 2020-04 on its financial statements and disclosures.

In August 2020, the FASB issued ASU 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40). The new standard reduces the number of accounting models for convertible debt instruments and convertible preferred stock. Limiting the accounting models results in fewer embedded conversion features being separately recognized from the host contract as compared with current U.S. GAAP. Convertible instruments that continue to be subject to separation models are (1) those with embedded conversion features that are not clearly and closely related to the host contract, that meet the definition of a derivative, and that do not qualify for a scope exception from derivative accounting and (2) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital. The standard also amends the guidance for the derivatives scope exception for contracts in an entity’s own equity. For non-public entities, ASU 2020-06 is effective for annual reporting periods beginning after December15, 2023, including interim periods within those fiscal years, and early adoption is permitted, but no earlier than fiscal years beginning after December15, 2020. The Company is in the process of completing its review of its existing convertible instruments under ASU 2020-06 and does not expect the adoption of ASU 2020-06 to have a material impact on its financial position, results of operations, or cash flows.

2.     Acquisition of City Semiconductor, Inc.

On May13, 2020, the Company acquired certain assets and liabilities of City Semiconductor, Inc. (“City Semi”), which has developed technology related to analog and mixed-signal integrated circuitry, with a focus on high-speed analog-to-digital converters and digital-to analog-intellectual property cores. The Company accounted for the acquisition as a business combination. The transaction costs associated with the acquisition were not material and were expensed as incurred. The acquisition date fair value of the consideration transferred for City Semi was approximately $2,029, which consisted of the following:

	Fair Value As of May 13, 2020
Class H units issued	$	711
Contingent consideration		1,180
Cash consideration to be transferred at a later date		138
Total	$	2,029

2.     Acquisition of City Semiconductor, Inc. (cont.)

The maximum contingent consideration payable in connection with the acquisition is $2,000. The acquisition date fair value of the contingent consideration was determined based on the Company’s assessment of the probability of achieving the performance targets that ultimately obligate the Company to transfer additional consideration to the seller. 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 this target 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 condensed consolidated statement of operations. The fair value of the first and second tranche contingent consideration liabilities was $500 and $960, respectively, as of March31, 2021, and $500 and $900, respectively, as of December31, 2020. The fair value of the first tranche contingent consideration liability is reflected in other current liabilities within the condensed consolidated balance sheet and the fair value of the second tranche contingent consideration liability is reflected in other long-term liabilities.

In connection with this acquisition, the two existing employees of City Semi, including the founder and sole shareholder of City Semi, entered into employment agreements with the Company. As there is a service condition associated with these agreements, the related compensation expense is accounted for separately from the acquisition. The Company recognizes the related compensation expense as research and development expense in the condensed consolidated statement of operations on a straight-line basis over the requisite service period.

The following table summarizes the fair values of assets acquired and liabilities assumed as of the date of acquisition:

	Fair Value As of May 13, 2020
Intangible asset – Software license	$	139
Intangible asset – Developed technology		369
Goodwill		1,739
Deferred revenue		(41	)
Accrued expenses		(177	)
Net assets acquired	$	2,029

The Company estimates that the useful life of the acquired developed technology intangible asset is seven years and the useful life of the acquired software license intangible asset is approximately one year, which represents the remaining duration of the software license. The excess of purchase consideration over the fair value of net assets acquired was recorded as goodwill, which is primarily attributed to the assembled workforce. None of the goodwill recognized is expected to be deductible for income tax purposes.

There are no amounts of revenue and earnings of City Semi included in the Company’s condensed consolidated statement of operations for the three months ended March31, 2020.

Embry Convertible Subordinated Notes Payable

On December4, 2012, the Company entered into two convertible note and exchange agreements with an investor, pursuant to which the entire outstanding principal of $3,500 and corresponding accrued interest of $107 held under existing loan agreements were exchanged for two convertible subordinated notes with aggregate principal amounts of $2,604 and $1,003. The convertible subordinated notes bore interest of 0.93% per annum, which is compounded annually. The aggregate principal and all accrued and unpaid interest were due in full on December4, 2017. On December3, 2017, the Company entered into a 12-month extension of these two convertible note and exchange agreements.

On December3, 2018, the Company entered into a 36-month extension of these two convertible note and exchange agreements. The interest rate on the 36-month extension was amended to 3.07% per annum. The Company recorded a discount on this convertible debt extension and a corresponding increase in additional paid-in capital related to the enhanced value of the embedded conversion options. The Company is amortizing the discount to interest expense over the 36-month extension period.

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 may be converted to 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”). Cézanne subsequently submitted a written notice of conversion to the Company in February 2021 to exercise its right to convert at the SPAC transaction closing on or before December31, 2021. As the conversion is contingent upon the successful closure of the closing of the SPAC transaction, the Company concluded a conversion event did not occur and the Embry convertible notes should remain as debt as of March31, 2021.

At March31, 2021 and December31, 2020, the total carrying value of the convertible subordinated notes payable, net of unamortized discount, was $3,526 and $3,496, respectively. Total accrued interest as of March31, 2021 and December31, 2020 was $488 and $458, respectively, and is included in accrued expenses and other current liabilities on the Company’s condensed consolidated balance sheets. Contractual interest incurred related to the convertible subordinated notes was $31 and $30 for the three months ended March31, 2021 and 2020, respectively, and is included in interest expense in the Company’s condensed consolidated statements of operations.

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 basis points above the prime rate in effect, or 4.25% on outstanding borrowings. The terms of the loan and security agreement have been amended from time to time, with the most recent amendment dated June8, 2021 (see Note 16 — Subsequent Events for further information). The amendments have extended the maturity date of the loan and adjusted the financial covenants’ borrowing limits. In August 2017 and as part of an amendment to the loan and security agreement, the Company issued warrants to PacWest to purchase 3,388 Membership Units.

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 January30, 2020. In addition, the amendments modified certain financial covenants, including the Company maintain a minimum cash balance of $2,300 and adjusted the borrowing limits to $2,000. The maturity date of the revolving line of credit has been amended to the earlier of July20, 2021 (see Note 16 — Subsequent Events for further information regarding the transaction).

As of March31, 2021 and December31, 2020, the Company had no outstanding balance on the term loan.

Contractual interest incurred related to the term loan and line of credit was $18 and $8 for the three months ended March31, 2021 and 2020, respectively, and is included in interest expense in the Company’s condensed consolidated statements of operations. The amortization of the debt discount resulted in interest expense of $0 and $6 for the three months ended March31, 2021 and March31, 2020, respectively, and is also included in interest expense in the Company’s condensed consolidated statements of operations.

As of March31, 2021 and December31, 2020, the revolving line of credit had an outstanding balance of $1,675. The Company’s borrowings under the term loan and revolving line of credit were subject to an aggregate borrowing limit of $2,000 as of March31, 2021 and December31, 2020. Total borrowings at any given time under the agreement are limited to a percentage of domestic accounts receivables less than 90 days past due and other factors.

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%. In connection with such loan, the Company issued 6,250 warrants to Trinity to acquire 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 has 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.

The new loan has a maturity date of October1, 2024 and bears interest equal to the greater of 10.75% or the Prime Rate plus 7.5%. The term loan may be prepaid by paying the principal and interest plus a prepayment fee ranging from 4.0% to 1.0% of the principal being repaid, depending on the length of time between the effective date and the prepayment date. Upon final repayment, an end-of-term fee of $720 must be paid by the Company to Trinity. The term loan is collateralized by substantially all of the Company’s assets to the extent they are not already securing the senior debt of PacWest.

As of March31, 2021 and December31, 2020, the Company had $11,407 and $11,335 outstanding under the Trinity Term loans, respectively, net of the unamortized discount and issuance cost generated as a result of the warrant issuance described in Note 9 — Members’ Equity. The debt discount and issuance costs are being amortized through

interest expense over the term of the loan using the effective interest method. The old loan required monthly interest only payments of $141 until November 2019 when repayment of principal began, and payments increased to $493 per month. The new loan requires interest only payments of $108 until October 2021 when repayment of principal begins, and payments increase to $391 per month with an effective interest rate of 15.8%.

Paycheck Protection Program

In April 2020, the Company applied for a loan pursuant to the Paycheck Protection Program of the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) as administered by the U.S. Small Business Administration (the “SBA”). In May 2020, the loan was approved, and the Company received the 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). 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 against any individual shareholder, except to the extent that such party uses the loan proceeds for an unauthorized purpose.

6.     Debt (cont.)

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 costs. Forgiveness is reduced if full-time headcount declines, or if salaries and wages for employees with salaries of $100,000 or less annually are reduced by more than 25%. No assurance can be given that the Company will obtain forgiveness of the PPP Loan either in whole or in part. Accordingly, the Company accounts for the PPP Loan as part of long-term debt.

The future maturities of the convertible debt, term loans, PPP loan, and revolving line of credit are collectively as follows:

2021 (remaining nine months)	$	8,570
2022		5,377
2023		4,006
2024 and thereafter		2,981

7.     Simple Agreements for Future Equity

During the year ended December31, 2020, the Company entered into SAFEs with existing investors and third-party investors for total proceeds of $25,765. The SAFEs require that the Company issue equity to the SAFE holders in exchange for their investment upon an equity raise of at least $35,000. The conversion price of the equity to be issued in exchange for the SAFE investment would be equal to the lower of a 25% discount to the equity issued or such price that implies the pre-money valuation of the Company is $250,000 for the SAFEs issued to existing investors while the SAFEs issued to new third-party investors have a pre-money valuation of $350,000 (all other features are the same). In the event of a dissolution, the SAFE holders are entitled to receive payment in the amount of the original purchase amount, in preference to any membership units. In the event of a liquidation, the SAFE holders are entitled to redeem the SAFE for two times the original purchase amount. In the event of a change in control of the Company, the SAFE holders receive a return of their purchase price for the SAFE. Certain SAFE holders may convert the SAFE into preferred units of the Company if change of control or another exit event has not occurred prior to December31, 2021. The SAFEs have no interest rate or maturity date, and the SAFE holders have no voting rights prior to conversion.

The SAFEs are recorded at fair value at issuance and remeasured at each reporting date. Changes in fair value are recorded in other income (expense), net in the condensed consolidated statement of operations. The fair value of the SAFEs was $83,600 and $102,700 as of March31, 2021 and December31, 2020, respectively. The changes in the fair value of the SAFEs are reflective of changes in the valuation of the Company as the Company evaluates strategic opportunities. See Note 8 — Fair Value Measurements.

8.     Fair Value Measurements

The Company’s debt instruments are recorded at their carrying values in its condensed 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 approximate their carrying values. The following table presents the Company’s Embry convertible notes carrying and fair values:

Level 3 Disclosures

The SAFEs were valued using a probability-weighted expected return method (“PWERM”) valuation approach aligned to the SAFE provisions, including (i) conversion through qualified equity financing, (ii) conversion through acquisition of a special purpose acquisition company, (iii) no conversion through equity or acquisition prior to December31, 2021, (iv) a liquidation event, and (v) a dissolution event. Determining the fair value of the SAFEs using the PWERM requires assumptions and estimates for both the probability of each scenario and the fair value determined under each scenario. The SAFEs were valued through each scenario using an appropriate valuation approach, including calculations based on the terms of the SAFEs and a Monte Carlo simulation, which utilized the Geometric Brownian Motion formula to simulate the conversion and payout of the SAFEs. The significant unobservable inputs include the discount rate, constant volatility factor and the Geometric Brownian Motion. Significant increases (decreases) in any of those inputs in isolation would result in a significantly lower (higher) fair value measurement.

9.     Members’ Equity (cont.)

Following the Company’s announcement of the Master Transactions Agreement (“MTA”), PacWest issued a letter dated February3, 2021 to the Company demanding 52,632 warrants in satisfaction of the provisions contained in the August9, 2017 credit facility amendment. On June8, 2021, the Company and PacWest entered into a settlement agreement and mutual release where both parties acknowledged and agreed that the original 3,388 warrants issued were in full compliance of the 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 2 — Acquisition of City Semiconductor.

As of March31, 2021 and December31, 2020, the Company owned 50% of its subsidiary, Wuxi. From time to time, Wuxi has sold equity ownership and the transactions have reduced the Company’s controlling interest in Wuxi on the condensed consolidated balance sheets. As of March31, 2021, the Company maintained majority ownership interest in Wuxi and a controlling financial interest.

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.

10.     Noncontrolling Interest

The Company’s ownership of Wuxi was 50% as of March31, 2021 and December31, 2020. From time to time, Wuxi has sold equity ownership and the transactions have reduced the Company’s controlling interest in Wuxi on the condensed consolidated balance sheets. As of March31, 2021, the Company maintained majority ownership interest in Wuxi and a controlling financial interest.

Disaggregation of Revenue

The Company disaggregates revenue from contracts with customers by geographic region, as the Company’s management believes it best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors.

The following tables present revenue disaggregated by geography of the customer’s shipping location for the three months ended March31, 2021 and 2020:

	Product revenue				Contract revenue
	Three months ended March 31,				Three months ended March 31,

South Korea		—		634		—		—
Total	$	7,483	$	4,225	$	631	$	438

Contract Balances

Contract assets or contract liabilities are recorded depending on the timing of revenue recognition, billings and cash collections on a contract-by-contract basis. Contract liabilities primarily relate to deferred revenue, including advance consideration received from customers for contracts prior to the transfer of control to the customer, and therefore revenue is recognized upon delivery of products and services or as the services are performed. The Company recorded contract assets of $0 and $55 at March31, 2021 and December31, 2020, respectively. The balance represents unbilled revenue and is included in prepaid expenses and other current assets in the accompanying consolidated balance sheets.

11.     Revenue (cont.)

The following table presents the contract liabilities as of March31, 2021 and December31, 2020:

	March 31, 2021		December 31, 2020
Deferred revenue	$	1,101	$	1,665

As of March31, 2021 and December31, 2020, contract liabilities were included as deferred revenue and classified as current liabilities in the condensed consolidated balance sheets.

During the three months ended March31, 2021 and 2020, the Company recognized $631 and $420, respectively, of revenue related to amounts that were previously included in contract liabilities at the beginning of the period. Deferred revenue decreased $564 from December31, 2020 to March31, 2021 due to the timing of payments received from customers.

Revenue related to remaining performance obligations represents the amount of contracted development arrangements that has not been recognized, which includes deferred revenue on the on the unaudited condensed consolidated balance sheet and unbilled amounts that will be recognized as revenue in future periods. As of March31, 2021, the amount of performance obligations that have not been recognized as revenue was $2,127, of which approximately 62% is expected to be recognized as revenue over the next twelve months and the remainder thereafter. This amount excludes the value of remaining performance obligations for contracts with an original expected length of one year or less. Variable consideration that has been constrained is excluded from the amount of performance obligations that have not been recognized.

Concentrations

Revenues for the three months ended March31, 2021 and 2020 include sales to one significant customer and their subcontractors, totaling approximately $4,972, or 61%, and $3,348, or 72%, of total revenue and percentage of total revenue, respectively, for the three months ended March31, 2021 and 2020, respectively. The loss of this customer would have a material impact on the Company’s condensed consolidated financial results.

The two largest customers represented 59% and 12% of accounts receivable as of March31, 2021 and the two largest customers represented 35% and 12% of accounts receivable as of December31, 2020. No other individual customer represented more than 10% of accounts receivable at either March31, 2021 or December31, 2020.

12.     Unit-Based Compensation

Per the Company’s operating agreement, the Company may issue Class B Units (“profits interests”, “units”) to employees, directors and consultants of the Company. Class B Units entitle the holders of such units to a share of the Company’s profits and distributions of the Company’s assets to the extent their capital accounts are positive. Holders of Class B Units do not have voting rights except to the extent required by law.

The board of directors has authorized 513,846 units for grant under the operating agreement. As of March31, 2021, 367,927 Class B Units were granted, and 145,919 units remained available for grant. All awards are subject to the terms of the Company’s operating agreement and the related Class B Unit purchase agreements, including forfeiture.

The Class B units are incentive units of the Company subject to vesting and certain restrictions. The Class B unit generally has a four-year vesting schedule, in which 25% of units vest after 12months and the remaining 75% vest monthly over the following three-year period.

In the event of voluntary or involuntary termination of the holder of the profit interest, the Company has the right, but not the obligation, to repurchase the profit interest at fair market value (the “Repurchase Right”), at any time during the 180-day period following the cessation of service from the unit holder.

12.     Unit-Based Compensation (cont.)

The profit interests are equity-classified awards. The Company has had a history of net losses and is in an accumulated deficit position. No compensation cost will be recognized until a change of control qualifying event is deemed probable to occur as the vested units are considered to have no value until distributions are made. Upon occurrence of a qualifying change of control performance condition, the compensation cost will be recognized in full for vested awards.

The following table summarizes activity related to profit interests for the three months ended March31, 2021:

	Number of units		Weighted- average grant date fair value
Nonvested profit interests as of December 31, 2020	138,195		$	72.68
Granted	—		$	—
Vested	(22,702	)	$	44.56
Forfeited	—		$	—
Nonvested profit interests as of March 31, 2021	115,493		$	80.44

As of March31, 2021 and December31, 2020, there was $11,745 and $11,573, respectively, of total unrecognized compensation cost related to profit interests. These unrecognized compensation costs will be recognized in full when a change of control satisfying the in-substance performance condition becomes probable.

The grant date fair value of the profit interests is determined using the Monte Carlo simulation. The significant assumptions used in valuation include the constant risk-free rate, constant volatility factor and the Geometric Brownian Motion. The following table presents the weighted average assumptions used in the valuations for grants in the three months ended March31, 2021:

	March 31, 2021
Constant risk free rate	0.8	%
Constant volatility factor	40	%
Geometric Brownian Motion	0.981

There were no awards granted in the three months ended March31, 2020.

On January29, 2021, the Company entered into agreements with employees and nonemployees for a total of 62,998 contingently issuable restricted stock awards with a grant date fair value of $6.83 per share. The awards are restricted stock awards that are issued upon the closing of the potential transaction with Thunder Bridge II and vest upon the later of 180 days after the closing date of such transaction or the stated vesting schedule. The agreements contain stated vesting terms that include performance and service conditions. The performance conditions are not considered probable, and no expense has been recognized for the awards in the three months ended March31, 2021. The awards are settleable by the Company in common stock of the surviving entity of the potential transaction with Thunder Bridge II or in cash, at the Company’s discretion. As of March31, 2021, there was $430 of total unrecognized compensation cost related to the contingently issuable restricted stock awards. The unrecognized compensation costs will be recognized if the performance condition becomes probable and over the required service period.

Basic and diluted net income (loss) per common unit was calculated as follows:

Numerator:
Net income (loss)	$	10,361		$	(5,380	)

Weighted average units outstanding – diluted		1,410,720			1,114,116

Net income (loss) per unit attributable to unit holders – diluted	$	(9.68	)	$	(4.60	)

Prior to the issuance of the financial statements as of March31, 2021, but after the period then ended, the Company completed a series of business transactions with Thunder Bridge II pursuant to the MTA. This transaction has materially impacted the number of shares outstanding. See Note 16 — Subsequent Events for more information regarding the transaction.

The Company’s potentially dilutive securities, which include unvested Class B 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 income (loss) per unit as the effect would be to reduce the net loss per unit. Therefore, in the three months ended March31, 2020, the weighted average number of shares outstanding used to calculate both basic and diluted net loss per unit attributable to unitholders is the same. The Company excluded the following potential units, presented based on amounts outstanding at each period end, from the computation of diluted net loss per unit attributable to unitholders for the periods indicated because including them would have had an antidilutive effect:

	Three months ended March 31,
	2021	2020
SAFEs	—	19,554
Class B unvested units	115,493	43,348
Convertible preferred units	1,146,047	1,141,547

14.     Income Taxes

The Company recorded a provision for income taxes of $13 and $3 for the three months ended March31, 2021 and 2020, respectively, related to its operations in the UK. As of March31, 2021, the Company continues to maintain a full valuation allowance against certain deferred tax assets due primarily from its history of generating net operating losses and future projection of tax losses.

15.     Commitments and Contingencies

Litigation

The Company may be a party to routine claims or litigation incidental to its business. The Company does not believe that it is a party to any pending legal proceeding that is likely to have a material adverse effect on its business, financial condition or results of operations.

Lease Commitments

In July 2015, the Company entered into a five-year operating lease for its 14,881 square foot headquarters in Aliso Viejo, California, which is payable monthly with periodic rent adjustments over the lease term. The lease requires a security deposit of $30, which is recorded in other assets on the Company’s condensed consolidated balance sheets as well as a tiered, time-based letter of credit that has now reached its lowest tier of $200. Subsequently, the lease was extended through the end of June 2023.

In October 2015, the Company entered into a five-year operating lease for its Scotland Design Center in Edinburgh, Scotland, which is payable monthly with periodic rent adjustments over the lease term. The lease expired in October 2020. During 2019, the Company entered into a sub-lease agreement with a third party for the Scotland Design Center facility. Separately, effective January 2020, the Company entered into a lease for a property in Scotland. The lease agreement has a term through December 2022 and monthly rent of approximately $19.

In August 2017, the Company entered into a lease assignment and assumption agreement for its design center in Austin, Texas. Rent for the associated office is payable monthly with periodic rent adjustments over the lease term, which expires in April 2021.

In October 2017, the Company entered into a 26-month operating lease for its Wuxi sales and design center. Rent for the associated office is payable monthly with periodic rent adjustments over the lease term. The lease was subsequently extended through December 2021.

In April 2020, the Company entered into a lease for a location in Shanghai, China. The lease expires in February 2022. Rent is approximately $3 per month.

In June 2020, the Company entered into a month-to-month lease for a location in San Francisco for approximately $1 a month.

Tax Distributions

To the extent the Company has funds legally available, the board of directors will approve distributions to each member, prior to March 15 of each year, in an amount per unit that, when added to all other distributions made to such member with respect to the previous calendar year, equals the estimated federal and state income tax liabilities applicable to such member as the result of its, his or her ownership of the units and the associated net taxable income allocated with respect to such units for the previous calendar year. There were no distributions approved by the board of directors or paid by the Company during the months ended March31, 2021 and 2020.

16.     Subsequent Events

For its condensed consolidated financial statements as of March31, 2021 and the three months then ended, management reviewed and evaluated material subsequent events from the condensed consolidated balance sheet date of March31, 2021 through June16, 2021, the date the condensed consolidated financial statements were issued.

SAFE Issuance

During April 2021, the Company entered into SAFEs with a third-party investor for a total purchase amount of $5,000. The SAFEs require that the Company issue equity to the SAFE holders in exchange for their investment upon an equity financing (including a SPAC transaction) with an aggregate purchase price of at least $35,000.

The equity issued in exchange for the SAFEs was determined based on using a conversion price assuming a valuation cap of $460,000 at the close of the transaction with Thunder Bridge II on June10, 2021.

PacWest Revolving Line of Credit Amendment

On June8, 2021, the Company entered into an amendment that extended the maturity date of the revolving credit facility with PacWest to July21, 2021. Other than the change in maturity date, there were no material changes to the terms of the credit facility.

Transactions with Thunder Bridge II

On June10, 2021, the Company completed a series of transactions (the “Transaction”) with Thunder Bridge II pursuant to the Master Transactions Agreement dated December14, 2020, as amended on May31, 2021. 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 Thunder Bridge II, and a merger subsidiary of Surviving Pubco was merged with and into Thunder Bridge II. Immediately prior to the closing of the Transaction (the “Closing”), shareholders of Thunder Bridge II redeemed an aggregate of approximately 9.9million common shares of Thunder Bridge II and the outstanding common shares and warrants of Thunder Bridge II were converted into approximately 24.6million Class A shares of Surviving Pubco and 12.3million warrants to purchase Class A shares of Surviving Pubco. Concurrent with the Closing, Thunder Bridge II raised $150,000 in a PIPE financing, pursuant to which Surviving Pubco issued 15million Class A shares. Surviving Pubco changed its name to indie Semiconductor, Inc.

Immediately prior to the Transaction, (i) the Company’s existing warrants to purchase the Company’s Class G units were net exercised and 10,021 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 Cezanne notes and the interest accrued thereunder were converted into an aggregate of 185,000 Class A units and 100,000 Class C units; and (iv) all of the Class C, D, E, F and G units of the Company were converted into an aggregate of 1,251,566 Class A Units of the Company. Immediately thereafter, each outstanding Class A Unit and Class B units was split into approximately 27.8 Class A units and Class B units, respectively.

The Transaction was accounted for as a reverse recapitalization in accordance with GAAP. Under the guidance in ASC 805, indie Semiconductor 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 SEC registrant, 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 future reported financial position and results is an estimated $400,000 in gross cash proceeds from the merger transaction and a net increase in cash (as compared to our consolidated balance sheet at December31, 2020) of approximately $335,000. The estimate includes roughly $150,000 in proceeds from a private placement (“PIPE Investment”) that was consummated in conjunction with the Transaction offset by additional transaction costs incurred in connection with the Transaction plus the retirement of indie’s long-term debt.

Report of Independent Registered Public Accounting Firm

To the Members and Board of Directors

Ay Dee Kay, LLC:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Ay Dee Kay, LLC, d/b/a indie Semiconductor, and subsidiaries (the Company) as of December31, 2020 and 2019, the related consolidated statements of operations, comprehensive loss, members’ equity (deficit) and noncontrolling interest, and cash flows for each of the years in the two-year period ended December31, 2020, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December31, 2020 and 2019, and the results of its operations and its cash flows for each of the years in the two-year period ended December31, 2020, in conformity with U.S. generally accepted accounting principles.

Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has suffered recurring losses from operations and negative cash flows from operating activities and has a net capital deficiency that raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

/s/ KPMG LLP

We have served as the Company’s auditor since 2017.

The Company engages subcontractors to manufacture its products. The majority of these subcontractors are located in Asia.

Going Concern

In accordance with Accounting Standards Update (“ASU”) 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40), the Company has evaluated whether there are certain conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued.

Since its inception, the Company has funded its operations with proceeds from the sales of Member units including Preferred Units and borrowing funds via convertible subordinated notes, term loans, venture debt, convertible debt and a revolving line of credit. These borrowings are subject to covenants, the failure to meet such covenants could result in the outstanding balance becoming immediately due and payable.

Primarily as a result of ongoing product development investments, the Company has incurred recurring losses and negative cash flows from operating activities since its inception, including net operating losses of $19,241 and $18,910 for the years ended December31, 2020 and 2019, respectively. Net losses, which amongst other things include the impact of fair value changes in the Company’s Simple Agreement for Future Equity (SAFE) liabilities and interest expenses, were $98,364 and $20,940, for the years ended December31, 2020 and 2019, respectively, of which $866 and $486 was attributable to the noncontrolling interest for the years ended December31, 2020 and 2019, respectively. As of December31, 2020, the Company had an accumulated deficit of $153,264. The Company expects to continue to invest in product development and generate operating losses in the future. As of the issuance date of the annual financial statements for the year ended December31, 2020, the Company recognizes the possibility that its cash and cash equivalents will not be sufficient to fund its operating expenses, capital expenditure requirements and debt service payments for the subsequent twelve months without raising additional capital to finance its operations.

On December14, 2020, the Company entered into a merger agreement with Thunder Bridge Acquisition II, Ltd. (“Thunder Bridge”) (the “Merger Agreement”). The Company is pursuing the consummation of a merger with Thunder Bridge under the Merger Agreement. If the merger is unable to be completed and the Company is not able to secure alternative sources of financing, the Company will be forced to reduce operating expenditures, which could adversely affect its business prospects, or the Company may be unable to continue operations. Although management continues to pursue these plans, there is no assurance that the Company will be successful in obtaining sufficient funding on terms acceptable to the Company to fund continuing operations, if at all.

Based on its recurring losses from operations and negative cash flows from operating activities incurred since inception, the expectation of continuing operating losses in the future, and the need to raise additional capital to finance its future operations, as of the issuance date of the annual financial statements for the year ended December31, 2020, the Company has concluded that there is substantial doubt about its ability to continue as a going concern within one year after the date that the financial statements are issued.

1) Nature of the Business and Basis of Presentation (cont.)

The accompanying financial statements do not include any adjustments that might result from the outcome of this uncertainty. Accordingly, the financial statements have been prepared on a basis that assumes the Company will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities and commitments in the ordinary course of business.

Risks and Uncertainties

In December 2019, COVID-19 was first reported to the World Health Organization (“WHO”), and in January 2020, the WHO declared the outbreak to be a public health emergency. In March 2020, the WHO characterized COVID-19 as a pandemic. Since then, the COVID-19 pandemic (the “Pandemic”) and efforts to control its spread have significantly curtailed the movement of people, goods, and services worldwide. The duration and extent of the Pandemic depends on future developments that cannot be accurately predicted at this time, such as the extent and effectiveness of containment and mitigation actions. It has already had an adverse effect on the global economy, and the ultimate societal and economic impact of the Pandemic remains unknown. Concerns over the economic impact of the Pandemic have caused volatility in financial and other capital markets, which may adversely affect the Company’s ability to access capital markets in the future.

The Company experienced a decrease in customer demand and product shipments in the second quarter of fiscal year 2020. This decrease was primarily the result of closures or reduced capacity at customer manufacturing facilities in China. During the second half of fiscal year 2020, customer manufacturing facilities re-opened and demand increased. The Company has transitioned to a remote work environment for its employees and, during the second and third fiscal quarters of 2020, reduced discretionary spending. As customer demand increased during the second half of fiscal year 2020, the semiconductor industry, and automotive semiconductors in particular, experienced material shortages and supply constraints. Given the Company’s reliance on third-party manufacturing suppliers, these industry dynamics present a significant risk to the Company. The Company has reduced discretionary spending and transitioned to a remote work environment for its employees. However, the Company cannot predict the duration or magnitude of the pandemic or the full impact that it may have on the Company’s financial condition, operations, and workforce. The Company will continue to actively monitor the rapidly evolving situation related to the Pandemic and may take further actions that alter the Company’s operations, including those that may be required by federal, state or local authorities, or that the Company determines are in the best interests of its employees and other third parties with whom the Company does business.

Basis of Presentation

The consolidated financial statements are prepared in accordance with accounting principles generally accepted 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 Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). The consolidated financial statements include the accounts of Ay Dee Kay, LLC, its wholly owned subsidiaries ADK LLC, a California entity, Ay Dee Kay Limited, a private limited company incorporated under the laws of Scotland, indie GmbH, a private limited liability company incorporated under the laws of Germany, its majority owned subsidiary, Wuxi indie Microelectronics (“Wuxi”), a Chinese entity 50% owned by the Company as of December31, 2020 and Wuxi’s wholly owned subsidiary indie Semiconductor HK, 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 members’ equity (deficit) in the consolidated balance sheets, and a noncontrolling interest in the consolidated statements of operations and consolidated statements of members’ equity (deficit) and noncontrolling interest (see Note 2 — Summary of Significant Accounting Policies — Consolidation).

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 for excess and obsolete inventories; (iii) warranty obligations; (iv) the value assigned to and estimated useful lives of long-lived assets; (v) the realization of tax assets and estimates of tax liabilities and tax reserves; (vi) the measurement of non-marketable equity securities; (vii) amounts recorded in connection with acquisitions; (viii) recoverability of intangible assets and goodwill; (ix) the recognition and disclosure of fair value of convertible debt and contingent liabilities; (x) the computation of unit-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 associated with various contractual arrangements, and valuation of assets acquired in connection with acquisitions. 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

The Company’s foreign subsidiaries use the local currency as their functional currency. Accordingly, foreign currency assets and liabilities are translated at the rate of exchange existing at the consolidated balance sheet date, and income and expense amounts are translated at the average of the monthly exchange rates. Gains or losses from foreign currency transactions are included in foreign currency translation adjustments in the consolidated statements of comprehensive loss.

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. The Company accounts for investments in which it has significant influence but not a controlling interest using the equity method of accounting. See Note 6 — Equity Method Investment.

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 December31, 2020 and 2019, cash and cash equivalents consisted of cash deposits that were held by reputable financial institutions in local jurisdictions of the Company’s subsidiaries including the U.S., Great Britain, and China denominated in U.S. dollars and local currency.

2) Summary of Significant Accounting Policies (cont.)

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.

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;

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

(amounts in thousands, except unit and per unit amounts)

2) Summary of Significant Accounting Policies (cont.)

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, convertible debt, and unit-based awards. 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 remeasures its simple agreements for future equity (SAFEs) and contingent considerations associated with the business combination using Level 3 fair value measurements.

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 is the chief executive officer. The Company has one business activity and there are no segment managers who are held accountable for operations, operating results and plans for levels or components below the consolidated unit level. Accordingly, the Company has one operating segment, and therefore, one reportable segment.

Revenue

Revenue is 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, 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.

The Company has agreements with certain distribution customers which may include certain rights of return and pricing programs, including stock rotation and price protection which affect the transaction price. Sales to these customers and programs offered are in accordance with terms set forth in written agreements, which require the Company to assess the potential revenue effects of this variable consideration utilizing the expected value method. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. As such, revenue on sales to customers that include rights of return and pricing programs are recorded net of estimated variable consideration, utilizing the expected value method based on historical sales data. Pricing adjustments on these items have not been historically significant.

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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(amounts in thousands, except unit and per unit amounts)

2) Summary of Significant Accounting Policies (cont.)

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.

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 December31, 2020 and 2019, 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 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.

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 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 costs. All research and development costs are expensed as incurred.

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 are expensed as incurred.

2) Summary of Significant Accounting Policies (cont.)

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 wrote off $116 and $3 of accounts receivable, for the years ended December31, 2020 and 2019, respectively.

Inventory, Net

The Company values inventories at the lower of cost or net realizable value. 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.

Intangible Assets, Net

The Company’s intangible assets include intellectual property (“IP”) and software licensed from third parties. The IP and software licenses have finite lives and are amortized over a period of three to eight years, on a straight-line basis, which approximates the pattern in which economic benefits of the IP and software is expected to be utilized.

Impairment of Long-Lived Assets

The Company reviews its long-lived assets, consisting of property and equipment 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 did not record any impairment to long-lived assets for the years ended December31, 2020 and 2019.

2) Summary of Significant Accounting Policies (cont.)

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.

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 October1, 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.

Debt Issuance Costs

In relation to the issuance of the outstanding term loans discussed in Note 10 — Debt, there is a balance of $48 and $77 of debt issuance costs as of December31, 2020 and 2019, respectively. The debt issuance costs are being amortized using the effective interest method over the terms of the underlying obligation and are included in interest expense in the consolidated statements of operations.

Unit-Based Compensation

The Company has a long-term incentive plan and awards Class B Units (“profit interests”) to its employees and non-employee consultants. Profit interests represent an interest in the profits and losses and distributions of the Company. The profit interests, which are non-voting, are accounted for under ASC 718, Compensation — Stock Compensation. The fair value of the equity-classified awards is determined using a Monte-Carlo simulation as of the grant date. The awards are subject to a substantive performance condition involving a change of control, upon which, all the unvested units accelerate and become fully vested. The Company has had a history of net losses and is in an accumulated deficit position. No compensation cost will be recognized until a change of control qualifying event is deemed probable to occur as the vested units are considered to have no value until distributions are made. As of the date of these financial statements, the performance condition was not deemed probable and accordingly, no stock compensation expense was recognized. The expense that would become recognizable upon satisfaction of the performance conditions are disclosed in Note 16 — Unit-Based Compensation.

2) Summary of Significant Accounting Policies (cont.)

Income Taxes

Ay Dee Kay, LLC is a limited liability company for U.S. federal income tax purposes and has elected to be treated as a partnership for income tax purposes. The Company is not subject to income tax, instead it may be subject to certain tax fees imposed by the states. The Company records these tax fees as general and administrative expenses because they are not considered income taxes under ASC 740, Income Taxes. As such, all income taxes and other related information are passed directly to the members and subject to income tax at the members’ level.

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 December31, 2020 and 2019, 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 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. Then the Company 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 December31, 2020 and 2019, 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 December31, 2020 and 2019, no accrued interest or penalties are recorded on the consolidated balance sheet, and the Company has not recorded any related expenses.

Comprehensive Loss

Foreign currency translation adjustments of $158 and ($81) represent the difference between net loss and comprehensive loss for the year ended December31, 2020 and 2019, respectively.

Net Loss Per Common Unit

The Company follows the two-class method when computing net loss per common unit as the Company has issued units that meet the definition of participating securities. The two-class method determines net loss per common unit for each class of common and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method requires income available to common unitholders for the period to be allocated between common and participating securities based upon their respective rights to receive dividends as if all income for the period had been distributed.

Basic net loss per common unit is computed by dividing the net loss attributable to Ay Dee Kay, LLC by the weighted average number of common units outstanding for the period. Diluted net loss per common unit is computed by adjusting net loss to reallocate undistributed earnings based on the potential impact of dilutive securities. Diluted net loss per common unit is computed including the impacts of potential dilutive common units.

2) Summary of Significant Accounting Policies (cont.)

The Company’s convertible preferred units contractually entitle the holders of such units to participate in dividends but do not contractually require the holders of such units to participate in losses of the Company. Accordingly, for the years ended December31, 2020 and 2019 in which the Company reported net losses, such losses are not allocated to such securities and diluted net loss per common unit is the same as basic net loss per common unit, since dilutive common units are not assumed to have been issued if their effect is anti-dilutive.

Recent Accounting Pronouncements

Recently Issued Accounting Pronouncements Not Yet Adopted

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”), whereby lessees will be required to recognize for all leases at the commencement date a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. A modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the consolidated financial statements must be applied. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. The FASB issued ASU 2019-10-Financial Instruments-Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates in November 2019 and ASU 2020-05-Revenue from Contracts with Customers (Topic 606) and Leases (Topic 842): Effective Dates for Certain Entities in June 2020. The ASUs change some effective dates for ASU 2016-02 on leasing. After applying ASU 2019-10 and 2020-05, ASU 2016-02 is effective for annual periods beginning after December15, 2021, and interim periods within fiscal years beginning after December15, 2022. The adoption of the new standard is expected to result in the recognition of additional lease liabilities and right-of-use assets as of January1, 2022. The Company is currently evaluating the impact of the new standard on the Company’s consolidated financial statements and related disclosures.

In June 2016, the FASB amended guidance related to impairment of financial instruments as part of ASU 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaces the incurred loss impairment methodology with an expected credit loss model for which a company recognizes an allowance based on the estimate of expected credit loss. This ASU requires entities to measure the impairment of certain financial instruments, including accounts receivable, based on expected losses rather than incurred losses. For non-public business entities, this ASU is effective for fiscal years beginning after December 15, 2022, with early adoption permitted, and will be effective for the Company beginning in 2023. The Company is currently evaluating the impact of the new standard on the Company’s consolidated financial statements and related disclosures.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) — Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles of ASC 740, Income Taxes. The amendments also improve consistent application of and simplify GAAP for other areas of ASC 740 by clarifying and amending existing guidance. ASU 2019-12 is effective for fiscal years beginning after December 15, 2020 (and December15, 2021 for nonpublic companies) and early adoption is permitted. Depending on the amendment, adoption may be applied on a retrospective, modified retrospective, or prospective basis. The Company is currently assessing the impact that this standard will have on its consolidated financial statements and related disclosures.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848), which provides optional expedients and exceptions to contract modifications and hedging relationships that reference the London Interbank Offered Rate or another reference rate expected to be discontinued. The standard is effective upon issuance through December 31, 2022 and may be applied at the beginning of the interim period that includes March12, 2020 or any date thereafter. However, ASU 2020-04 will only be available for a limited time (generally through December31, 2022). The Company is currently evaluating the impact of the reference rate reform and ASU 2020-04 on its financial statements and disclosures.

2) Summary of Significant Accounting Policies (cont.)

In August 2020, the FASB issued ASU 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40). The new standard reduces the number of accounting models for convertible debt instruments and convertible preferred stock. Limiting the accounting models results in fewer embedded conversion features being separately recognized from the host contract as compared with current U.S. GAAP. Convertible instruments that continue to be subject to separation models are (1) those with embedded conversion features that are not clearly and closely related to the host contract, that meet the definition of a derivative, and that do not qualify for a scope exception from derivative accounting and (2) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital. The standard also amends the guidance for the derivatives scope exception for contracts in an entity’s own equity. For non-public entities, ASU 2020-06 is effective for annual reporting periods beginning after December15, 2023, including interim periods within those fiscal years, and early adoption is permitted, but no earlier than fiscal years beginning after December15, 2020. The Company is in the process of completing its review of its existing convertible instruments under ASU 2020-06 and does not expect the adoption of ASU 2020-06 to have a material impact on its financial position, results of operations, or cash flows.

3) Acquisition of City Semiconductor, Inc.

On May13, 2020, the Company acquired certain assets and liabilities of City Semiconductor, Inc. (“City Semi”), which has developed technology related to analog and mixed-signal integrated circuitry, with a focus on high-speed analog-to-digital converters and digital-to analog-intellectual property cores. The Company accounted for the acquisition as a business combination. The transaction costs associated with the acquisition were not material and were expensed as incurred. The acquisition date fair value of the consideration transferred for City Semi was approximately $2,029, which consisted of the following:

	As of May 13, 2020
Class H units issued	$	711
Contingent consideration		1,180
Cash consideration to be transferred at a later date		138
Total	$	2,029

The maximum contingent consideration payable in connection with the acquisition is $2,000. The acquisition date fair value of the contingent consideration was determined based on the Company’s assessment of the probability of achieving the performance targets that ultimately obligate the Company to transfer additional consideration to the seller. 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 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. As of December31, 2020, the fair value of the first and second tranche contingent consideration liabilities was $500 and $900, respectively. The fair value of the first tranche contingent consideration liability is reflected in other current liabilities within the consolidated balance sheet and the fair value of the second tranche contingent consideration liability is reflected in other long-term liabilities.

In connection with the acquisition, the two existing employees of City Semi, including the founder and sole shareholder of City Semi, entered into employment agreements with the Company. As there is a service condition associated with these agreements, the related compensation expense is accounted for separately from the acquisition. The Company recognizes the related compensation expense as research and development expense in the consolidated statement of operations on a straight-line basis over the requisite service period.

Net assets acquired	$	2,029

The Company estimates that the useful life of the acquired developed technology intangible asset is seven years and the useful life of the acquired software license intangible asset is approximately one year, which represents the remaining duration of the software license. The excess of purchase consideration over the fair value of net assets acquired was recorded as goodwill, which is primarily attributed to the assembled workforce. None of the goodwill recognized is expected to be deductible for income tax purposes.

The amounts of revenue and earnings of City Semi included in the Company’s consolidated statement of operations from the acquisition date of May13, 2020 through December31, 2020 are $591 and ($396), respectively.

Embry Convertible Subordinated Notes Payable

On December4, 2012, the Company entered into two convertible note and exchange agreements with an investor, pursuant to which the entire outstanding principal of $3,500 and corresponding accrued interest of $107 held under existing loan agreements were exchanged for two convertible subordinated notes with aggregate principal amounts of $2,604 and $1,003. The convertible subordinated notes bore interest of 0.93% per annum, which is compounded annually. The aggregate principal and all accrued and unpaid interest were due in full on December4, 2017. On December3, 2017, the Company entered into a 12-month extension of these two convertible note and exchange agreements.

On December3, 2018, the Company entered into a 36-month extension of these two convertible note and exchange agreements. The interest rate on the 36-month extension was amended to 3.07% per annum. The Company recorded a discount on this convertible debt extension and a corresponding increase in additional paid-in capital related to the enhanced value of the embedded conversion options. The Company is amortizing the discount to interest expense over the 36-month extension period.

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 may be converted to 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.

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 basis points above the prime rate in effect, or 4.25%, on outstanding borrowings. The terms of the loan and security agreement have been amended from time to time, with the most recent amendment dated February21, 2021. The amendments have extended the maturity date of the loan and adjusted the financial covenants’ borrowing limits. In August 2017 and as part of an amendment to the loan and security agreement, the Company issued warrants to PacWest to purchase 3,388 Membership Units, see Note 19 — Commitments and Contingencies.

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 January30, 2020. In addition, the amendments modified certain financial covenants, including the Company maintain a minimum cash balance of $2,300 and adjusted the borrowing limits to $2,000. The maturity date of the revolving line of credit has been amended to April1, 2021, see Note 21 — Subsequent Events.

As of December31, 2020 and 2019, the Company had $0 and $981 outstanding on the term loan, net of the unamortized discount, respectively, generated as a result of the warrant issuance described in Note 13 — Members’ Equity. The discount associated with the term loan was fully amortized as of December31, 2020.

Contractual interest incurred related to the term loan and line of credit was $48 and $111 for the years ended December31, 2020 and 2019, respectively, and is included in interest expense in the Company’s consolidated statements of operations. The amortization of the debt discount resulted in interest expense of $19 and $25 for the years ended December31, 2020 and 2019, respectively, and is also included in interest expense in the Company’s consolidated statements of operations.

As of December31, 2020 and 2019, the revolving line of credit had an outstanding balance of $1,675 and $0, respectively. The Company’s borrowings under the term loan and revolving line of credit were subject to an aggregate borrowing limit of $2,000 and $10,000 as of December31, 2020 and 2019, respectively.

10) Debt (cont.)

In October 2020, the Company entered into a new loan agreement with Trinity, which replaced the March 2018 agreement. The new loan has 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.

The new loan has a maturity date of October1, 2024 and bears interest equal to the greater of 10.75% or the Prime Rate plus 7.5%. The term loan may be prepaid by paying the principal and interest plus a prepayment fee ranging from 4.0% to 1.0% of the principal being repaid, depending on the length of time between the effective date and the prepayment date. Upon final repayment, an end-of-term fee of $720 must be paid by the Company to Trinity. The term loan is collateralized by substantially all of the Company’s assets to the extent they are not claimed by the senior debt holder, PacWest.

As of December31, 2020 and 2019, the Company had $11,335 and $14,323 outstanding under the Trinity Term Loans, respectively, net of the issuance cost and unamortized discount generated as a result of the warrant issuance described in Note 13 — Members’ Equity. The debt discount and issuance costs are being amortized through interest expense over the term of the loan using the effective interest method. The old loan required monthly interest only payments of $141 until November 2019 when repayment of principal began and payments increased to $493 per month. The new loan requires interest only payments of $108 until October 2021 when repayment of principal begins and payments increase to $391 per month with an effective interest rate of 15.8%.

Contractual interest incurred related to the term loans was $1,523 and $1,785 for the years ended December31, 2020 and 2019, respectively, and is included in interest expense in the Company’s consolidated statements of operations. The amortization of the debt discount and cost of issuance resulted in interest expense of $129 and $53 for the years ended December31, 2020 and 2019, respectively, and is also included in interest expense in the Company’s consolidated statements of operations.

This loan, along with other outstanding debt are 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.

units in an equity financing transaction for aggregate gross proceeds in excess of $20,000 and the financing occurs prior to the maturity of the loan. The loan is convertible into the same class of units as issued in the qualifying equity financing transaction at a conversion price of 75% of the cash received per unit. Interest expense related to the loan was $220 and $0 for the years ended December31, 2020 and 2019, respectively, and is included in interest expense in the Company’s consolidated statements of operations. The note was amended on January21, 2021 to extend the maturity date to the earlier of December31, 2021 or the closing of the merger with Thunder Bridge described in Note 1 — Nature of the Business and Basis of Presentation. Additionally, the January21, 2021 amendment removed the conversion rights associated with the loan. See Note 21 — Subsequent Events.

Paycheck Protection Program

In April 2020, the Company applied for a loan pursuant to the Paycheck Protection Program of the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) as administered by the U.S. Small Business Administration (the “SBA”). In May 2020, the loan was approved, and the Company received the 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 against any individual shareholder, except to the extent that such party uses the loan proceeds for an unauthorized purpose.

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 costs. Forgiveness is reduced if full-time headcount declines, or if salaries and wages for employees with salaries of $100,000 or less annually are reduced by more than 25%. No assurance can be given that the Company will obtain forgiveness of the PPP Loan either in whole or in part. Accordingly, the Company accounts for the PPP Loan as part of long-term debt.

The future maturities of the convertible debt, term loans, PPP loan, and revolving line of credit are as follows:

2021	$	8,488
2022		5,359
2023		4,005
2024 and thereafter		2,981

11) Simple Agreements for Future Equity

During the year ended December31, 2020, between March 2020 and October 2020, the Company entered into SAFEs with existing investors and third-party investors for total proceeds of $25,765. The SAFEs require that the Company issue equity to the SAFE holders in exchange for their investment upon an equity raise of at least $35,000. The conversion price of the equity to be issued in exchange for the SAFE investment would be equal to the lower of a 25% discount to the equity issued or such price that implies the pre-money valuation of the Company is $250,000 for the SAFEs issued to existing investors while the SAFEs issued to new third-party investors have a pre-money valuation of $350,000 (all other features are the same). In the event of a dissolution, the SAFE holders are entitled to receive payment in the amount of the original purchase amount, in preference to any membership units. In the event

of a liquidation, the SAFE holders are entitled to redeem the SAFE for two times the original purchase amount. In the event of a change in control of the Company, the SAFE holders receive a return of their purchase price for the SAFE. Certain SAFE holders may convert the SAFE into preferred units of the Company if change of control or another exit event has not occurred prior to December31, 2021. The SAFEs have no interest rate or maturity date and the SAFE holders have no voting rights prior to conversion.

The SAFEs are recorded at fair value at issuance and remeasured at each reporting date. Changes in fair value are recorded in other income (expense) in the consolidated statement of operations. The fair value of the SAFEs was $102,700 as of December31, 2020. The increase in the fair value of the SAFEs is reflective of changes in the valuation of the Company as the Company evaluates strategic opportunities. See Note 12 — Fair Value Measurements.

12) 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 debt is determined using valuation inputs categorized as Level 3. The fair values of the Company’s term loans and Tropez convertible debt generally approximate their carrying values. The following table presents the Company’s Embry convertible debt carrying and fair values:

	December 31, 2020				December 31, 2019
	Carrying value		Fair value		Carrying value		Fair value
Convertible debt	$	3,496	$	103,200	$	3,375	$	3,750

As of December31, 2019, the Company did not have any financial assets or liabilities measured at fair value. The following table presents the Company’s fair value hierarchy for financial assets and liabilities measured as of December31, 2020:

	Fair Value Measurements as of December 31, 2020
	Level 1		Level 2		Level 3		Total
Liabilities:

First Tranche Contingent Consideration	$	—	$	—	$	500	$	500
Second Tranche Contingent Consideration	$	—	$	—	$	900	$	900

Level 3 Disclosures

The SAFEs were valued using a probability-weighted expected return method (PWERM) valuation approach aligned to the SAFE provisions, including (i) conversion through qualified equity financing, (ii) conversion through acquisition of a special purpose acquisition company, (iii) no conversion through equity or acquisition prior to December31, 2021, (iv) a liquidation event, and (v) a dissolution event. Determining the fair value of the SAFEs using the PWERM requires assumptions and estimates for both the probability of each scenario and the fair value determined under each scenario. The SAFEs were valued through each scenario using an appropriate valuation approach, including calculations based on the terms of the SAFEs and a Monte Carlo simulation, which utilized the Geometric Brownian

13) Members’ Equity(cont.)

On July25, 2017, the Company issued 112,916 Class E units to investors at an original issue price of $35.42 per unit for cash consideration of $3,963, net of issuance costs of $37.

The Company has issued warrants to purchase Class G Units as part of amendments to the terms of debt agreements with Trinity and PacWest, see Note 10 — Debt. In connection with entering into the term loan agreement with Trinity in March 2018, the Company issued 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 19 — Commitments and Contingencies). On October1, 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. All warrants can be exercised through payment of the exercise price or by net share settlement and the holders of Class G units do not have voting rights.

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 — Acquisition of City Semiconductor.

As of December31, 2020 and 2019, the Company owned 50% and 63% of its subsidiary, Wuxi, respectively. From time to time, Wuxi has sold equity ownership and the transactions have reduced the Company’s controlling interest in Wuxi on the consolidated balance sheets. As of December31, 2020, the Company maintained majority ownership interest in Wuxi and a controlling financial interest.

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.

13) Members’ Equity(cont.)

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.

14) Noncontrolling Interest

The Company’s ownership of Wuxi was 50% and 63% as of December31, 2020 and 2019, respectively. From time to time, Wuxi has sold equity ownership and the transactions have reduced the Company’s controlling interest in Wuxi on the consolidated balance sheets. As of December31, 2020, the Company maintained majority ownership interest in Wuxi and a controlling financial interest.

Contract Balances

Contract assets or contract liabilities are recorded depending on the timing of revenue recognition, billings and cash collections on a contract-by-contract basis. Contract liabilities primarily relate to deferred revenue, including advance consideration received from customers for contracts prior to the transfer of control to the customer, and therefore revenue is recognized upon delivery of products and services or as the services are performed. The Company recorded contract assets of $55 and $0 at December21, 2020 and 2019, respectively. The balance represents unbilled revenue and is included in prepaid expenses and other current assets in the accompanying consolidated balance sheets.

The following table presents the changes in contract liabilities during the years ended December31, 2020 and 2019 after the effects of the adoption of ASC 606 on January1, 2019:

	December 31,				January 1, 2019
	2020		2019
Deferred revenue	$	1,665	$	3,486	$	4,528

As of December31, 2020 and 2019, contract liabilities were included as deferred revenue and classified as current liabilities in the consolidated balance sheets.

During the year ended December31, 2020 and 2019, the Company recognized $2,143 and $1,722, respectively, of revenue related to amounts that were previously included in contract liabilities at the beginning of the year. Deferred revenue decreased $1,042 from January1, 2019 to December31, 2019 and decreased $1,821 from December31, 2019 to December31, 2020 due to the timing of payments received from customers.

Revenue related to remaining performance obligations represents the amount of contracted development arrangements that has not been recognized. As of December31, 2020, the amount of performance obligations that have not been recognized as revenue was $2,774, of which approximately 62% is expected to be recognized as revenue over the next twelve months and the remainder thereafter. This amount excludes the value of remaining performance obligations for contracts with an original expected length of one year or less. Variable consideration that has been constrained is excluded from the amount of performance obligations that have not been recognized.

Concentrations

Revenues for the years ended December31, 2020 and 2019 include sales to one significant customer and its subcontractors, totaling approximately $12,877 or 57% of total revenue for 2020 and $17,423 or 77% of total revenue for 2019. The loss of this customer would have a material impact on the Company’s consolidated financial results.

15) Revenue(cont.)

The two largest customers represented 34% and 12% of accounts receivable as of December31, 2020 and the two largest customers represented 40% and 20% of accounts receivable as of December31, 2019. No other individual customer represented more than 10% of accounts receivable at either December31, 2020 or 2019.

16) Unit-Based Compensation

Per the Company’s operating agreement, the Company may issue Class B Units (“profits interests”, “units”) to employees, directors and consultants of the Company. Class B Units entitle the holders of such units to a share of the Company’s profits and distributions of the Company’s assets to the extent their capital accounts are positive. Holders of Class B Units do not have voting rights.

The board of directors has authorized 513,846 units for grant under the agreement. As of December31, 2020, 367,927 Class B Units were granted, and 145,919 units remained available for grant. All awards are subject to the terms of the Company’s operating agreement, including forfeiture.

The Class B units are incentive units of the Company subject to vesting and certain restrictions. The standard Class B unit has a four-year vesting schedule, in which 25% of units vest after 12months and the remaining 75% vest monthly over the following three-year period. Upon (1) a change of control and (2) termination of employment other than for cause or if the grantee resigns for good reason, all the unvested units accelerate and become fully vested. Non-standard Class B unvested units will accelerate and become fully vested upon (i) a capital raise of $50,000, (ii) the Company achievement of $150,000 in trailing twelve-month revenue or (iii) a change in control or firm commitment underwritten public offering.

In the event of voluntary or involuntary termination of the holder of the profit interest, the Company has the right, but not the obligation, to repurchase the profit interest at fair market value (the “Repurchase Right”), at any time during the 180-day period following the cessation of service from the unit holder.

The profit interests are equity-classified awards. The Company has had a history of net losses and is in an accumulated deficit position. No compensation cost will be recognized until a change of control qualifying event is deemed probable to occur as the vested units are considered to have no value until distributions are made. Upon occurrence of a qualifying change of control performance condition, the compensation cost will be recognized in full for vested awards.

The following table summarizes activity related to profit interests for the years ended December31, 2020:

	Number of units		Weighted average grant date fair value
Nonvested profit interests as of December 31, 2019	61,492		$	2.58
Granted	120,800		$	91.30
Vested	(31,758	)	$	15.23
Forfeited	(12,339	)	$	2.51
Nonvested profit interests as of December 31, 2020	138,195		$	72.68

As of December31, 2020 and 2019, there was $11,348 and $369, respectively, of total unrecognized compensation cost related to profit interests. These unrecognized compensation costs will be recognized in full when a change of control satisfying the in-substance performance condition becomes probable.

16) Unit-Based Compensation (cont.)

The grant date fair value of the profit interests is determined using the Monte Carlo simulation. The significant assumptions used in valuation include the constant risk free rate, constant volatility factor and the Geometric Brownian Motion. The following table presents the weighted average assumptions used in the valuations for grants in the years ended December31, 2020 and 2019:

	December 31,

Constant risk free rate	1.5	%	2.4	%
Constant volatility factor	54	%	50	%
Geometric Brownian Motion	0.853		0.798

17) Net Loss Per Common Unit

Basic and diluted net loss per common unit was calculated as follows:

	Year Ended December 31,
	2020			2019
Numerator:
Net loss	$	(98,364	)	$	(20,940	)
Less: Net loss attributable to noncontrolling interest		(866	)		(486	)
Net loss attributable to common unitholders	$	(97,498	)	$	(20,454	)
Denominator:
Weighted average shares used to compute net loss per unit attributable to common unitholders, basic and diluted		1,124,864			1,100,423
Net loss per unit attributable to common unitholders, basic and diluted	$	(86.68	)	$	(18.59	)

The Company’s potentially dilutive securities, which include unvested Class B Units, preferred units, warrants for Class A units, and convertible debt, have been excluded from the computation of diluted net loss per unit as the effect would be to reduce the net loss per unit. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per unit attributable to common unitholders is the same. The Company excluded the following potential common units, presented based on amounts outstanding at each period end, from the computation of diluted net loss per unit attributable to common unitholders for the periods indicated because including them would have had an antidilutive effect:

	Year Ended December 31,
	2020	2019
Class B unvested units	138,195	61,492
Preferred units	1,146,047	1,141,547
Warrants to purchase Class G units	11,482	9,638
Convertible debt into Class A and Class C Units	285,000	285,000

18) Income Taxes(cont.)

Changes in the valuation allowance for deferred tax assets during the years ended December31, 2020 and 2019, are as follows:

	2020		2019
Valuation Allowance as on January 1st	$	617	$	126

Valuation Allowance as on December 31st	$	1,040	$	617

As of December31, 2020, the Company has approximately $4,374 of net operating loss carryforwards primarily in China that begin to expire at various dates through 2025.

In evaluating its ability to realize its net deferred tax assets, the Company considered all available positive and negative evidence, such as past operating results, forecasted earnings, prudent and feasible tax planning strategies, and the future realization of the tax benefits of existing temporary differences. The Company determined that it was not possible to reasonably quantify future taxable income and, considering its history of generating net operating losses, determined that it is more likely than not that its net deferred tax assets in China will not be realized. As a result, the Company continues to maintain a full valuation allowance as of December31, 2020 and 2019 for its China operations. The Company’s net deferred tax liability position is the result of the UK operations.

The Company does not provide for foreign income and withholding, U.S. Federal, or state income taxes or tax benefits on 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 plan to indefinitely reinvest on a quarterly basis. In making its decision to indefinitely reinvest, the Company evaluates its plans of reinvestment, its ability to control repatriation and to mobilize funds without triggering basis differences, and the profitability of U.S. operations and their cash requirements and the need, if any, to repatriate funds. If the assessment of the Company with respect to earnings of non-U.S. subsidiaries changes, deferred U.S. income taxes, foreign income taxes, and foreign withholding taxes may have to be accrued. At this time, determination of the unrecognized deferred tax liabilities for temporary differences related to the Company’s investment in non-US subsidiaries is not practicable.

A reconciliation of the federal statutory income tax rate to the effective tax rate for the years ended December31, 2020 and 2019 are as follows:

The calculation of the Company’s tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations for the jurisdictions in which it operates or does business in. 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.

18) Income Taxes(cont.)

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 December31, 2020 and 2019, 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 general and administrative expenses. As of December31, 2020 and 2019, 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 2016 to the present.

19) Commitments and Contingencies

Litigation

The Company may be a party to routine claims or litigation incidental to its business. The Company does not believe that it is a party to any pending legal proceeding that is likely to have a material adverse effect on its business, financial condition or results of operations.

In connection with a credit facility amendment executed with PacWest on August 9, 2017, the Company agreed to issue the bank warrants to acquire Membership Units. In 2018, the Company and the bank agreed that 3,388 warrants would be issued at a strike price of $35.42 per unit, which was subsequently reflected in the Company’s books and records. Following the Company’s announcement of the Master Transactions Agreement (MTA), on February3, 2021, PacWest issued a letter to the Company demanding 52,632 warrants in satisfaction of the provisions contained in the August9, 2017 credit facility amendment. The Company has offered PacWest warrants for the amount the Company believes it is obligated to provide. While the Company believes the bank’s claims are unfounded and subject to meritorious defenses, the ultimate resolution of the matter, which is expected to occur within one year from the date of the financial statements, could result in the Company issuing a number of warrants higher than the Company believes it is contractually obligated to provide. An estimate of any cost of the resolution of these claims cannot be made as the number of and fair value of any additional warrants that may ultimately be issued based on the final resolution cannot be determined at this time. The Company expects any outcome could be settled in warrants and could result in additional equity dilution to the Company.

Lease Commitments

In July 2015, the Company entered into a five-year operating lease for its 14,881 square foot headquarters in Aliso Viejo, California, which is payable monthly with periodic rent adjustments over the lease term. The lease requires a security deposit of $30, which is recorded in other assets on the Company’s consolidated balance sheets as well as a tiered, time-based letter of credit that has now reached its lowest tier of $200. Subsequently, the lease was extended through the end of June 2023.

In October 2015, the Company entered into a five-year operating lease for its Scotland Design Center in Edinburgh, Scotland, which is payable monthly with periodic rent adjustments over the lease term. The lease expired in October 2020. During 2019, the Company entered into a sub-lease agreement with a third party for the Scotland Design Center facility. Separately, effective January 2020, the Company entered into a lease for a property in Scotland. The lease agreement has a term through December 2022 and monthly rent of approximately $19.

Note 1 — Organization and Plan of Business Operations

Thunder Bridge Acquisition II, Ltd. (the “Company”) is a newly organized blank check company incorporated as a Cayman Islands exempted company on February13, 2019. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (a “Business Combination”). The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended (the “Securities Act”), as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”).

All activity for the period from February13, 2019 (date of inception) through August13, 2019 relates to the Company’s formation and its initial public offering (the “Initial Public Offering”), which is described in Note 3.

The registration statement for the Initial Public Offering was declared effective on August8, 2019. On August13, 2019 the Company consummated the Initial Public Offering of 34,500,000 units (“Units” and, with respect to the Class A ordinary shares included in the Units offered, the “Public Shares”), generating gross proceeds of $345,000,000, which is described in Note 3.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 8,650,000 warrants (the “Private Placement Warrants”) at a price of $1.00 per warrant in a private placement to Thunder Bridge Acquisition II, LLC (the “Sponsor”), generating gross proceeds of $8,650,000, which is described in Note 4.

Following the closing of the Initial Public Offering, on August13, 2019, an amount of $345,000,000 ($10.00 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the sale of the Private Placement Warrants was placed in a trust account (“Trust Account”) which may be invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 180 days or less or in any open-ended investment company that holds itself out as a money market fund selected by the Company meeting the conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the consummation of a Business Combination or (ii) the distribution of the Trust Account, as described below.

Transaction costs amounted to $19,483,537 consisting of $6,900,000 of underwriting fees, $12,075,000 of deferred underwriting fees (see Note 6) and $508,537 of other costs. In addition, $1,230,680 of cash was held outside of the Trust Account and is available for working capital purposes.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. The Company’s initial Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (excluding any deferred underwriting commissions and taxes payable on the income earned on the Trust Account) at the time of the signing an agreement to enter into a Business Combination. However, the Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act. There is no assurance that the Company will be able to successfully effect a Business Combination.

The Company will provide the holders of the public shares (the “Public Shareholders”) with the opportunity to redeem all or a portion of their public shares upon the completion of the Business Combination, either (i) in connection with a shareholder meeting called to approve the Business Combination or (ii) by means of a tender offer, in either case at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Business Combination, including interest (which interest shall be net of taxes payable) divided by the number of then outstanding public shares. Notwithstanding the foregoing, if the Company seeks shareholder approval of the Business Combination and the Company does not conduct redemptions pursuant to the tender offer rules, a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined in Section 13(d)(3) of the Securities

Note 1 — Organization and Plan of Business Operations (cont.)

Exchange Act of 1934, as amended (the “Exchange Act”), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the public shares. In connection with any shareholder vote required to approve any Business Combination, the Sponsor and any other shareholder of the Company prior to the consummation of the Public Offering (collectively with the Sponsor, the “Initial Shareholders”) and the Company’s directors and officers will agree (i) to vote any of their respective Ordinary Shares (as defined below) in favor of the initial Business Combination and (ii) not to redeem any of their Ordinary Shares in connection therewith. The Company will proceed with a Business Combination only if it has net tangible assets of at least $5,000,001 upon consummation of the Business Combination and, in the case of a shareholder vote, a majority of the outstanding Ordinary Shares voted are voted in favor of the Business Combination.

The NASDAQ rules require that the Business Combination must be with one or more target businesses that together have an aggregate fair market value equal to at least 80% of the balance in the Trust Account (less any Deferred Commissions (as defined below) and taxes payable on interest earned) at the time of the Company signing a definitive agreement in connection with the Business Combination.

The Company will have until August13, 2021 to consummate a Business Combination (the “Combination Period”). If the Company has not completed a Business Combination within 24months of the closing of the Initial Public Offering, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable, and less up to $100,000 of interest to pay dissolution expenses) divided by the number of then outstanding public shares, which redemption will completely extinguish the rights of the Public Shareholders as shareholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and its Board of Directors, dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. In the event of a liquidation, the Public Shareholders will be entitled to receive a full pro rata interest in the Trust Account (initially anticipated to be approximately $10.00 per share, plus any pro rata interest earned on the Trust Fund not previously released to the Company and less up to $100,000 of interest to pay dissolution expenses). There will be no redemption rights or liquidating distributions with respect to the Founder Shares (as defined below) or the Private Placement Warrants, which will expire worthless if the Company fails to complete a Business Combination within the 24-month time period.

Note 2 — Significant Accounting Policies

Basis of Presentation

The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) and pursuant to the accounting and disclosure rules and regulations of the U.S. Securities and Exchange Commission.

Net Income Per Ordinary Share

Basic net income per ordinary share is computed by dividing net income applicable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period. Consistent with FASB 480, ordinary shares subject to possible redemption, as well as their pro rata share of undistributed trust earnings consistent with the two-class method, have been excluded from the calculation of loss per ordinary share for the three months ended March31, 2021 and 2020, respectively. Such shares, if redeemed, only participate in their pro rata share of trust earnings. Diluted loss per share includes the incremental number of shares of ordinary shares to be issued to settle warrants, as calculated using the treasury method. For the three months ended March31, 2021 and 2020, the Company did not have any dilutive warrants, securities or other contracts that could potentially, be exercised or converted into ordinary shares. As a result, diluted loss per ordinary share is the same as basic loss per ordinary share for all periods presented.

Note 2 — Significant Accounting Policies(cont.)

A reconciliation of net loss per ordinary share as adjusted for the portion of income that is attributable to ordinary shares subject to redemption is as follows:

	For the Three Months Ended March 31,
	2021			2020
Net income	$	38,507,524		$	6,779,032
Less: Income attributable to ordinary shares		(8,621	)		(1,788,302	)
Net income available to ordinary shares	$	38,498,903		$	4,990,730
Weighted average shares outstanding, basic and diluted		8,625,000			8,625,000
Basic and diluted net income per ordinary share	$	4.46		$	0.58

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents are carried at cost, which approximates fair value.

Use of Estimates

The preparation of financial statements in conformity with US 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 date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates.

Ordinary shares subject to possible redemption

The Company accounts for its ordinary shares subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Ordinary shares subject to mandatory redemption (if any) is classified as a liability instrument and is measured at fair value. Conditionally redeemable ordinary shares (including ordinary shares that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) is classified as temporary equity. At all other times, ordinary shares is classified as shareholders’ equity. The Company’s ordinary shares features certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at March31, 2021, ordinary shares subject to possible redemption is presented as temporary equity, outside of the shareholders’ equity section of the Company’s balance sheet.

Offering costs

Offering costs consist of legal, accounting, underwriting fees and other costs incurred through the balance sheet date that are directly related to our initial public offering. Offering costs amounting to $19,483,537, of which $18,509,360 were charged to shareholders’ equity upon the completion of our initial public offering, with the balance expensed as a cost of the warrant liability.

Income Taxes

The Company accounts for income taxes under FASB ASC 740, Income Taxes (“ASC 740”). ASC 740 requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the financial statement and tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carry forwards. ASC 740 additionally requires a valuation allowance to be established when it is more likely than not that all or a portion of deferred tax assets will not be realized.

F-69

THUNDER BRIDGE ACQUISITION II, LTD.
NOTES TO THE CONDENSED FINANCIAL STATEMENTS
(Unaudited)

Note 2 — Significant Accounting Policies(cont.)

ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits as of March31, 2021. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position.

There is currently no taxation imposed on income by the Government of the Cayman Islands.

Recent Accounting Pronouncements

Management does not believe that any other recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying financial statements.

Emerging Growth Company

Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which at times, may exceed the Federal depository insurance coverage of $250,000. The Company has not experienced losses on these accounts.

Financial Instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB ASC 820, Fair Value Measurements and Disclosures, approximates the carrying amounts represented in the balance sheet.

Derivative Financial Instruments

The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, “Derivatives and Hedging”. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued at each reporting date, with changes in the fair value reported in the statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the balance sheet as current or non-current based on whether or not net-cash settlement or conversion of the instrument could be required within 12months of the balance sheet date.

Management of the Company evaluates events that have occurred after the balance sheet date of March31, 2021 through the date these financial statements were issued. Based upon the review, management did not identify any recognized or non-recognized subsequent events that would have required adjustment or disclosure in the financial statements.

Note 3 — Initial Public Offering

Pursuant to the Initial Public Offering, the Company sold 34,500,000 Units at a purchase price of $10.00 per Unit. Each Unit consists of one Class A Share and one-half redeemable Warrant. Each whole warrant (“Public Warrant”) entitles the holder to purchase one Class A Share at a price of $11.50 per share (See Note 7).

Note 4 — Private Placement

Simultaneously with the Initial Public Offering, the Sponsor purchased an aggregate of 8,650,000 Private Placement Warrants at $1.00 per Private Placement Warrant, for an aggregate purchase price of $8,650,000 (the “Private Placement”). Each Private Placement Warrant is exercisable to purchase one share of Class A ordinary shares at an exercise price of $11.50. The proceeds from the Private Placement Warrants were added to the proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the proceeds of the sale of the Private Placement Warrants will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law) and the Private Placement Warrants will expire worthless. There will be no redemption rights or liquidating distributions from the Trust Account with respect to the Private Placement Warrants.

The Private Placement Warrants are identical to the Public Warrants underlying the Units sold in the Initial Public Offering, except that the Private Placement Warrants: (i) will not be redeemable by the Company; (ii) may be exercised for cash or on a cashless basis, so long as they are held by the Sponsor or any of its permitted transferees and (iii) are (including the ordinary shares issuable upon exercise of the Private Placement Warrants) entitled to registration rights. Additionally, the Sponsor has agreed not to transfer, assign or sell any of the Private Placement Warrants, including the Class A Shares issuable upon exercise of the Private Placement Warrants (except to certain permitted transferees), until 30 days after the completion of the Business Combination.

Founder Shares

On February19, 2019, an aggregate 8,625,000 Class B Shares (the “Founder Shares”) were sold to the Sponsor at a price of approximately $0.003 per share, for an aggregate price of $25,000. This number included an aggregate of up to 1,125,000 Founder Shares that were subject to forfeiture if the over-allotment option is not exercised in full by the Underwriters in order to maintain the Initial Shareholders’ ownership at 20% of the issued and outstanding Ordinary Shares upon completion of the Initial Public Offering. The Underwriters exercised their over-allotment option in full so none of the Founder Shares were forfeited. The Founder Shares are identical to the Class A Shares included in the Units being sold in the Initial Public Offering, except that the Founder Shares (i) have the voting rights described in Note8, (ii) are subject to certain transfer restrictions described below and (iii) are convertible into Class A Shares on a one-for-one basis, subject to adjustment pursuant to the anti-dilution provisions contained therein. The Founder Shares may not be transferred, assigned or sold until the earlier of (i) one year after the completion of the Business Combination and (ii) the date on which the Company completes a liquidation, merger, share exchange, reorganization or other similar transaction after the Business Combination that results in all of the Public Shareholders having the right to exchange their Class A Shares for cash, securities or other property. Notwithstanding the foregoing, if the last sale price of the Class A Shares equals or exceeds $12.00 per share (as adjusted for share splits, share dividends, rights issuances, subdivisions, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Business Combination, the Founder Shares will be released from the lock-up.

Private Placement Warrants

The sponsor purchased from the Company and aggregate of 8,650,000 Private Placement Warrants at $1.00 per Private Placement Warrant, for an aggregate purchase price of $8,650,000.

Administrative Services Agreement

The Company entered into an agreement whereby, commencing on August8, 2019 through the earlier of the consummation of a Business Combination or the Company’s liquidation, the Company will pay an affiliate of the Sponsor a monthly fee of $10,000 for office space, utilities and administrative support. The Company had incurred and paid $30,000 and $30,000 as of March31, 2021 and 2020, respectively.

Advisory Agreement

The Company entered into an agreement, whereby, commencing on August8, 2019 through the earlier of the consummation of a Business Combination or the Company’s liquidation, the Company will pay an affiliate of Chief Executive Officer a monthly fee of $20,000 for advisory services related to its search for and consummation of its Initial Business Combination. The Company had incurred and paid $60,000 and $60,000 as of March31, 2021 and 2020, respectively.

Related Party Loans

In order to finance transaction costs in connection with the Business Combination, the Sponsor or an affiliate of the Sponsor or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes the Business Combination, the Company would repay such loaned amounts. In the event that the Business Combination does not close, the Company may use a portion of the working capital held outside the trust account to repay such loaned amounts but no proceeds from the trust account would be used for such repayment. Up to $1,500,000 of such loans may be convertible into warrants at a price of $1.00 per warrant at the option of the lender. The warrants would be identical to the private placement warrants issued to the Sponsor. The terms of such loans by the Company’s officers and directors, if any, have not been determined and no written agreements exist with respect to such loans. The Company does not expect to seek loans from parties other than the Sponsor or its directors or officers or their respective affiliates as it does not believe third parties will be willing to loan such funds and provide a waiver against any and all rights to seek access to funds in the trust account. There were loans outstanding of $937,407 and $300,000 as of March31, 2021 and December31, 2020, respectively.

Financing Agreement

The Company and a member of the Sponsor entered into a letter agreement on August8, 2019, under the terms of which the Company will provide such member with a right of first refusal to provide up to 51% of any necessary debt financing in connection with the Company’s Business Combination and to act as lead agent and arranger in connection thereto.

Note Payable to Sponsor

On February20, 2019, the Sponsor and the Company executed an unsecured promissory note pursuant to which the Company may borrow up to $300,000 in the aggregate to cover the Initial Public Offering (the “Promissory Note”). The Promissory Note was non-interest bearing and payable on the earlier of December31, 2019 or the completion of the Initial Public Offering. On August13, 2019, the outstanding balance of $277,000 in borrowings outstanding under the Promissory Note was repaid.

Note 6 — Commitments

Registration Rights

Pursuant to a registration rights agreement entered into on August8, 2019, the holders of the Founder Shares, Private Placement Warrants (and their underlying securities) and the warrants that may be issued upon conversion of the Working Capital Loans (and their underlying securities) are entitled to registration rights. The holders of a majority of these securities are entitled to make up to three demands, excluding short form demands, that the Company register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of a Business Combination and rights to require the Company to register for resale such securities pursuant to Rule 415 under the Securities Act. However, the registration rights agreement provides that the Company will not permit any registration statement filed under the Securities Act to become effective until termination of the applicable lock-up period. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriters Agreement

The Company granted the underwriters a 45-day option to purchase up to 4,500,000 additional Units to cover over-allotments at the Initial Public Offering price, less the underwriting discounts and commissions, which was exercised on August13, 2019.

The underwriters were paid a cash underwriting discount of 2.0% of the gross proceeds of the Initial Public Offering, or $6,900,000. In addition, the underwriters are entitled to a deferred underwriting discount of 3.5% of the gross proceeds of the Initial Public Offering, or $12,075,000. The deferred commission was placed in the Trust Account and will be paid in cash upon the closing of a Business Combination, subject to the terms of the underwriting agreement.

Note 7 — Warrant Liability

Public Warrants may only be exercised for a whole number of shares. No fractional warrants will be issued upon separation of the Units and only whole warrants will trade. The Public Warrants will become exercisable on the later of (a) 30 days after the completion of a Business Combination or (b) 12months from the closing of the Initial Public Offering. The Public Warrants will expire five years after the completion of a Business Combination or earlier upon redemption or liquidation.

The Company is not obligated to deliver any Class A ordinary shares pursuant to the exercise of a warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act with respect to the Class A ordinary shares underlying the warrants is then effective and a prospectus relating thereto is current, subject to the Company satisfying its obligations with respect to registration. No warrant will be exercisable and the Company will not be obligated to issue any Class A ordinary shares upon exercise of a warrant unless Class A ordinary shares issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants.

Note 7 — Warrant Liability(cont.)

The Company has agreed that as soon as practicable, but in no event later than 15 business days, after the closing of a Business Combination, the Company will use its best efforts to file, and within 60 business days following a Business Combination to have declared effective, a registration statement covering the Class A ordinary shares issuable upon exercise of the warrants. The Company will use its reasonable best efforts to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the warrants in accordance with the provisions of the warrant agreement. Notwithstanding the above, if the Class A ordinary shares at the time of any exercise of a warrant not listed on a national securities exchange such that it satisfies the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, the Company will not be required to file or maintain in effect a registration statement, but will be required to use its best efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available.

Redemptions of Warrants — Once the warrants become exercisable, the Company may redeem the Public Warrants:

•        in whole and not in part;

•        at a price of $0.01 per warrant;

•        upon not less than 30 days’ prior written notice of redemption to each warrant holder; and

•        if, and only if, the reported last sale price of the Company’s Class A ordinary shares equals or exceeds $18.00 per share for any 20 trading days within a 30-trading day period ending three business days before the Company sends the notice of redemption to each warrant holder.

If and when the warrants become redeemable by the Company, the Company may exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state securities laws.

If the Company calls the Public Warrants for redemption, management will have the option to require all holders that wish to exercise the Public Warrants to do so on a “cashless basis,” as described in the warrant agreement. The exercise price and number of shares of Class A ordinary shares issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, or recapitalization, reorganization, merger or consolidation. However, the warrants will not be adjusted for issuance of Class A ordinary shares at a price below its exercise price. Additionally, in no event will the Company be required to net cash settle the warrants. If the Company is unable to complete a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of warrants will not receive any of such funds with respect to their warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with the respect to such warrants. Accordingly, the warrants may expire worthless.

In addition, if the Company issues additional ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of a Business Combination at a newly issued price of less than $9.20 per ordinary share (with such issue price or effective issue price to be determined in good faith by the Company’s board of directors, and in the case of any such issuance to the sponsor or its affiliates, without taking into account any Founder Shares held by the sponsor or such affiliates, as applicable, prior to such issuance), the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the newly issued price and the redemption price of the warrants shall be adjusted to equal 180% of the newly issued price.

The Private Placement Warrants are identical to the Public Warrants underlying the Units sold in the Initial Public Offering, except that the Private Placement Warrants and the Class A ordinary shares issuable upon the exercise of the Private Placement Warrants will not be transferable, assignable or saleable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Placement Warrants will be exercisable on a cashless basis and be non-redeemable so long as they are held by the initial purchasers or their permitted

transferees. If the Private Placement Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants.

At March31, 2021 and 2020, there were 17,250,000 whole public warrants and 8,650,000 private placement warrants outstanding, respectively, with a fair value of $57,614,968 and $97,181,794, respectively.

The Company accounts for the 17,250,000 warrants issued in connection with the Initial Public Offering and the 8,650,000 Private Placement Warrants in accordance with the guidance contained in ASC 815-40. Such guidance provides that because the warrants do not meet the criteria for equity treatment thereunder, each warrant must be recorded as a liability. The warrant agreement contains an Alternative Issuance provision that if less than 70% of the consideration receivable by the holders of the Class A common stock in the Business Combination is payable in the form of common equity in the successor entity, and if the holders of the warrants properly exercises the warrants within thirty days following the public disclosure of the consummation of Business Combination by the Company, the warrant price shall be reduced by an amount equal to the difference (but in no event less than zero) of (i) the warrant price in effect prior to such reduction minus (ii) (A) the Per Share Consideration (as defined below) minus (B) the Black-Scholes Warrant Value (as defined below). The “Black-Scholes Warrant Value” means the value of a Warrant immediately prior to the consummation of the Business Combination based on the Black-Scholes Warrant Model for a Capped American Call on Bloomberg Financial Markets. “Per Share Consideration” means (i) if the consideration paid to holders of the common stock consists exclusively of cash, the amount of such cash per common stock, and (ii) in all other cases, the volume weighted average price of the common stock as reported during the ten-trading day period ending on the trading day prior to the effective date of the Business Combination.

The Company believes that the adjustments to the exercise price of the warrants is based on a variable that is not an input to the fair value of a “fixed-for-fixed” option as defined under FASB ASC Topic No. 815 –40, and thus the warrants are not eligible for an exception from derivative accounting. The accounting treatment of derivative financial instruments requires that the Company record a derivative liability upon the closing of the Proposed Public Offering. Accordingly, the Company will classify each warrant as a liability at its fair value and the warrants will be allocated a portion of the proceeds from the issuance of the Units equal to its fair value determined by the Monte Carlo simulation. This liability is subject to re-measurement at each balance sheet date. With each such remeasurement, the warrant liability will be adjusted to fair value, with the change in fair value recognized in the Company’s statement of operations. The Company will reassess the classification at each balance sheet date. If the classification changes as a result of events during the period, the warrants will be reclassified as of the date of the event that causes the reclassification.

Preferred Shares

The Company is authorized to issue 1,000,000 preferred shares with a par value of $0.0001. The Company’s board of directors will be authorized to fix the voting rights, if any, designations, powers, preferences, the relative, participating, optional or other special rights and any qualifications, limitations and restrictions thereof, applicable to the shares of each series. The board of directors will be able to, without shareholder approval, issue preferred shares with voting and other rights that could adversely affect the voting power and other rights of the holders of the Ordinary Shares and could have anti-takeover effects.

At March31, 2021 and 2020, there were no preferred shares issued or outstanding.

Share; provided that only holders of the Class B Shares have the right to vote on the election of directors prior to the Business Combination. The Class B Shares will automatically convert into Class A Shares at the time of the Business Combination, on a one-for-one basis, subject to adjustment for share splits, share dividends, rights issuances, subdivisions, reorganizations, recapitalizations and the like, and subject to further adjustment as provided herein. In the case that additional Class A Shares, or equity-linked securities, are issued or deemed issued in excess of the amounts sold in the Initial Public Offering and related to the closing of the Business Combination, the ratio at which the Class B Shares shall convert into Class A Shares will be adjusted (unless the holders of a majority of the outstanding Class B ordinary shares agree to waive such anti-dilution adjustment with respect to any such issuance or deemed issuance) so that the number of Class A Shares issuable upon conversion of all Class B Shares will equal, in the aggregate, 20% of the sum of all Ordinary Shares outstanding upon completion of the Initial Public Offering plus all Class A Shares and equity-linked securities issued or deemed issued in connection with the Business Combination, excluding any Ordinary Shares or equity-linked securities issued, or to be issued, to any seller in the Business Combination, or any Private Placement-equivalent Warrants issued to the Sponsor or its affiliates upon conversion of loans made to the Company. Holders of Founder Shares may also elect to convert their Class B Shares into an equal number of Class A Shares, subject to adjustment as provided above, at any time.

At March31, 2021 and 2020, there were 7,540,460, and 3,437,357 Class A Shares issued and outstanding, (excluding 26,959,540 and 31,062,643 Class A shares subject to possible redemption), and there were 8,625,000 Class B Shares issued and outstanding, respectively.

Founder Shares

On February20, 2019, an aggregate of 8,625,000 Class B Shares (the “Founder Shares”) were sold to the Sponsor at a price of approximately $0.003 per share, for an aggregate price of $25,000. This number included an aggregate of up to 1,125,000 Founder Shares that were subject to forfeiture if the over-allotment option is not exercised in full by the Underwriters in order to maintain the Initial Shareholders’ ownership at 20% of the issued and outstanding Ordinary Shares upon completion of the Initial Public Offering. The Underwriters exercised their over-allotment option in full so none of the Founder Shares were forfeited. The Founder Shares are identical to the Class A Shares included in the Units sold in the Initial Public Offering, except that the Founder Shares (i) have the voting rights described in this Note7, (ii) are subject to certain transfer restrictions described below and (iii) are convertible into Class A Shares on a one-for-one basis, subject to adjustment pursuant to the anti-dilution provisions contained therein. The Founder Shares may not be transferred, assigned or sold until the earlier of (i) one year after the completion of the Business Combination and (ii) the date on which the Company completes a liquidation, merger, share exchange, reorganization or other similar transaction after the Business Combination that results in all of the Public Shareholders having the right to exchange their Class A Shares for cash, securities or other property.

Notwithstanding the foregoing, if the last sale price of the Class A Shares equals or exceeds $12.00 per share (as adjusted for share splits, share dividends, rights issuances, subdivisions, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Business Combination, the Founder Shares will be released from the lock-up agreement.

Pursuant to the MTA, subject to the terms and conditions set forth therein, upon the closing of the transactions contemplated thereby (the “Closing”): (i) Thunder Bridge II will domesticate into a Delaware corporation (the “Domestication”), (ii) TBII Merger Sub will merge with and into Thunder Bridge II (the “Thunder Bridge II Merger”) with Thunder Bridge II being the surviving corporation and pursuant to which Thunder Bridge II equity holders will receive corresponding shares in Surviving Pubco, (iii) ADK Merger Sub will merge with and into the Company (the “Company Merger”) with the Company being the surviving limited liability company (in such capacity after the Company Merger, the “Surviving Company”), (iv) the ADK Blockers will merge with and into ADK Blocker Merger Sub, with ADK Blocker Merger Sub being the surviving limited liability company (the “Blocker Mergers,”) and (v) ADK Service Provider Merger Sub will merge with and into ADK Service Provider Holdco, with ADK Service Provider Holdco being the surviving limited liability company (“Service Provider Merger,” and collectively with the Thunder Bridge II Merger, the Company Merger and the Blocker Mergers, the “Mergers,” and the Mergers collectively with the other transactions contemplated by the Merger Agreement, the “Transactions”). Following the Mergers, Surviving Pubco will be the successor issuer and public company pursuant to the federal securities laws, and Surviving Pubco’s corporate name will change to “indie Semiconductor, Inc.”

As a result of the Transactions, each issued and outstanding Class A ordinary share and Class B ordinary share of Thunder Bridge II will convert into a share of Class A common stock of Surviving Pubco, and each issued and outstanding warrant to purchase Class A ordinary shares of Thunder Bridge II will be exercisable by its terms to purchase an equal number of shares of Class A common stock of Surviving Pubco. Each share of Surviving Pubco Class A common stock will provide the holder with the rights to vote, receive dividends, share in distributions in connection with a liquidation and other stockholder rights with respect to Surviving Pubco.

Merger Consideration

The merger consideration (the “Merger Consideration”) to be paid to holders of the limited liability company interests of the Company (collectively, the “Company Equity Holders”) pursuant to the MTA will be an amount equal to 90,000,000shares of Class A common stock of Thunder Bridge II, subject to adjustment as described below, paid in either shares of Class A common stock of Surviving Pubco or limited liability company interests in the Company (valued at $10.00 per unit) (the “Post-Merger Company Units”), which will be exchangeable on a one-for-one basis for shares of Class A common stock of Surviving Pubco. The Merger Consideration is subject to adjustment downward for the amount that Company indebtedness exceeds Company indebtedness at closing.

Those Company Equity Holders that receive Post-Merger Company Units will also receive one share of Class V common stock of Surviving Pubco, which will have no economic rights in Surviving Pubco but will entitle the holder to vote as a stockholder of Surviving Pubco, with the number of votes equal to the number of Post-Merger Company Units held by the Company Equity Holder. After the Closing, each Company Equity Holder will be permitted to exchange its Post-Merger Company Unit for a share of Class A common stock of Surviving Pubco on a one-for-one basis.

The Earn Out

In addition to the consideration set forth above, the Company Equity Holders will also have a contingent earn out right to receive up to an additional 10,000,000shares of Class A common stock of Surviving Pubco (the “Earn Out Shares”) after the Closing based on the following:

•        If at any time following the Closing and prior to December31, 2027, the volume weighted average price of the Class A common stock of Surviving Pubco is greater than or equal to $12.50 over any 20 trading days within any 30 trading day period, the Company Equity Holders will be entitled to receive 50% of the Earn Out Shares; and

•        If at any time following the Closing and prior to December31, 2027, the volume weighted average price of the Class A common stock is greater than or equal to $15.00 over any 20 trading days within any 30 trading day period, the Company Equity Holders will be entitled to receive 100% of the remaining unissued Earn Out Shares.

Payments of the Earn Out Shares to holders of Class A common stock of the Surviving Pubco or holders of the Post-Merger Company Units will not depend on the holders continuing to hold the holders’ Class A common stock or Units, as the case may be, at the time of the payout of the Earn Out Shares.

The Earn Out Shares will be paid either in shares of Class A common stock of the Surviving Pubco, or in Post-Merger Company Units, valued at the applicable price target stated above. Holders of Class A common stock of the Surviving Pubco will be paid the Earn Out Shares in additional shares of Class A common stock of the Surviving Pubco. Holders of Post-Merger Company Units will be paid the Earn Out Shares in additional Post-Merger Company Units.

The price targets shall be equitably adjusted for stock splits, dividends, reorganizations, combinations, recapitalizations and similar transactions affecting the shares of Class A common stock of Surviving Pubco.

Notwithstanding the foregoing, if there is a Surviving Pubco Sale (as defined in the MTA) at any time following the Closing and prior to December31, 2027, then all of the remaining unissued Earn Out Shares will be deemed to be earned and will paid out to the Company Equity Holders.

Covenants of the Parties

Each party agreed in the MTA to use its reasonable best efforts to effect the Closing. The MTA also contains certain customary covenants by each of the parties during the period between the signing of the MTA and the earlier of the Closing or the termination of the MTA in accordance with its terms, including the conduct of their respective businesses, provision of information, notification of certain matters, obtaining governmental consents (including making any filings required under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”)), filing a registration statement and proxy statement soliciting the approval of Thunder Bridge II stockholders for the Transaction, terminating affiliate contracts, maintaining books and records, entering into a Paying and Exchange Agent Agreement for the distribution of the Merger Consideration and earned Earn Out Shares, establishing an equity incentive plan effective at the Closing, as well as certain customary covenants, such as publicity, that will continue after the termination of the MTA.

The foregoing description of the MTA and the Transactions do not purport to be complete and are qualified in their entirety by the terms and conditions of the MTA, a copy of which is filed as Exhibit 2.1 hereto and incorporated herein by reference.

The MTA contains representations, warranties and covenants that the respective parties made to each other as of the date of such agreement or other specific dates.

It is not intended to provide any other factual information about Thunder Bridge II, the Company or any other party to the MTA. In particular, the representations, warranties, covenants and agreements contained in the MTA, which were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to the MTA, may be subject to limitations agreed upon by the contracting parties (including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the MTA instead of establishing these matters as facts) and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors and reports and documents filed with the SEC.

to the MTA. In addition, the representations, warranties, covenants and agreements and other terms of the MTA may be subject to subsequent waiver or modification. Moreover, information concerning the subject matter of the representations and warranties and other terms may change after the date of the MTA, which subsequent information may or may not be fully reflected in Thunder Bridge II’s public disclosures.

Subscription Agreements

Contemporaneously with the execution of the MTA, Thunder Bridge II entered into separate Subscription Agreements with a number of subscribers (each a “Subscriber”), pursuant to which the Subscribers agreed to purchase, and Thunder Bridge II agreed to sell to the Subscribers, an aggregate of up to 15,000,000shares of Class A common stock of Thunder Bridge II (the “PIPE Shares”), in a private placement for a purchase price of $10.00 per share and an aggregate purchase price of $150million (the “PIPE Investments”).

The closing of the sale of the PIPE Shares pursuant to the Subscription Agreements is contingent upon, among other customary closing conditions, the substantially concurrent Closing of the Transactions. The purpose of the PIPE Investments is to raise additional capital for use by the Company following the Closing.

Pursuant to the Subscription Agreements, Thunder Bridge II agreed that, within 30 calendar days after the Closing, Thunder Bridge II (or its successor) will file with the SEC (at Thunder Bridge II’s sole cost and expense) a registration statement registering the resale of the PIPE Shares, and Thunder Bridge II shall use its commercially reasonable efforts to have such registration statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) the 90th calendar day (or 120th calendar day if the SEC notifies Thunder Bridge II that it will “review” the registration statement) following the Closing and (ii) the fifth business day after the date Thunder Bridge II is notified (orally or in writing, whichever is earlier) by the SEC that the registration statement will not be “reviewed” or will not be subject to further review.

The foregoing description of the Subscription Agreements does not purport to be complete and is qualified in its entirety by the terms and conditions of the Subscription Agreements, a form of which is filed as Exhibit 10.1 hereto, and is incorporated herein by reference.

Exchange Agreement

Concurrently with the completion of the Mergers, Surviving Pubco will enter into an exchange agreement with the Company and the Company Equity Holders receiving Post-Merger Company Units (the “Exchange Agreement”), which will provide for the exchange of Post-Merger Company Units into shares of Class A common stock of the Surviving Pubco. Holders of Post-Merger Company Units will, from and after the six-month anniversary of the Closing, be able to elect to exchange all or any portion of their Post-Merger Company Units for shares of Class A common stock by delivering a notice to the Surviving Pubco; provided, that Thunder Bridge II, at its sole election, may instead pay for such Post-Merger Company Units in cash based on the volume weighted average price of the Class A common stock. The initial exchange ratio will be one Post-Merger Company Unit for one share of Class A common stock, subject to certain adjustments.

The foregoing description of the Exchange Agreement does not purport to be complete and is qualified in its entirety by the terms and conditions of the Exchange Agreement, a copy of which is filed as Exhibit 10.2 hereto and is incorporated herein by reference.

Tax Receivable Agreement

Concurrently with the completion of the Transactions and as a condition precedent for the Closing, the Surviving Pubco will enter into the tax receivable agreement (the “Tax Receivable Agreement”) with certain holders of the Post-Merger Company Units (the “TRA Participants”). Pursuant to the Tax Receivable Agreement, the Surviving Pubco will be required to pay the TRA Participants 85% of the amount of savings, if any, in U.S. federal, state and

local income tax that the Surviving Pubco actually realizes as a result of (i) the increases in tax basis of the Surviving Company’s assets attributable to and resulting from any exchanges of Post-Merger Company Units for Class A common stock of Surviving Pubco and (ii) certain net operating loss carryforwards of the ADK Blockers inherited by Surviving Pubco in connection with the Transactions. All such payments to the TRA Participants will be the Surviving Pubco’s obligation, and not that of the Company.

The foregoing description of the Tax Receivable Agreement does not purport to be complete and is qualified in its entirety by the terms and conditions of the Tax Receivable Agreement, a copy of which is filed as Exhibit 10.3 hereto and is incorporated herein by reference.

Support Agreements

Simultaneously with the execution of the MTA, each of (i) the Sponsor and (ii) certain officers and directors of the Company and certain Company Equity Holders entered into support agreements (collectively, the “Support Agreements”) in favor of Thunder Bridge II and the Company and their present and future successors and subsidiaries.

In the Support Agreements for the officers and directors of the Company and certain Company Equity Holders, they each agreed to vote all of their Company membership interests in favor of the MTA and related transactions and to take certain other actions in support of the MTA and related transactions. The Support Agreements also prevent them from transferring their voting rights with respect to their Company membership interests or otherwise transferring their Company membership interests prior to the meeting of the Company’s members to approve the MTA and related transactions, except for certain permitted transfers.

In its Support Agreement, the Sponsor agreed with the Company to vote all of its equity interests in Thunder Bridge II in favor of the MTA and related transactions and to take certain other actions in support of the MTA and related transactions. The Support Agreement also prevents the Sponsor from transferring its voting rights with respect to its equity interests in Thunder Bridge II or otherwise transferring its equity interests in Thunder Bridge II prior to the meeting of Thunder Bridge II’s stockholders to approve the MTA and related transactions, except for certain permitted transfers.

The foregoing description of the Support Agreements does not purport to be complete and is qualified in its entirety by the terms and conditions of the Support Agreements, copies of which, or the forms of which, are filed as Exhibit 10.4 and Exhibit 10.5 hereto and incorporated by reference herein.

Sponsor Earnout Letter

Simultaneously with the execution of the MTA, the Sponsor entered into a letter agreement (the “Sponsor Letter Agreement”) with Thunder Bridge II and the Company, pursuant to which the Sponsor agreed at the Closing to deposit with Continental Stock Transfer and Trust Company, as escrow agent (the “Sponsor Escrow Agent”), 3,450,000shares of its Class B ordinary shares of Thunder Bridge II (including any shares of Surviving Pubco Class A common stock issued in exchange therefore in the Transactions, the “Escrow Shares”) to be held in escrow by the Sponsor Escrow Agent, along with any earnings or proceeds thereon. Fifty percent of the Escrow Shares will be released from escrow if at any time prior to December31, 2027, the closing price of shares of Class A common stock on the principal exchange on which such securities are then listed or quoted will have been at or above $12.50 for 20 trading days over a 30 trading day period, and 100% of the remaining Escrow Shares will be released from escrow if at any time prior to the seventh anniversary of the Closing the closing price of shares of Class A common stock on the principal exchange on which such securities are then listed or quoted will have been at or above $15.00 for 20 trading days over a 30 trading day period. Additionally, all of the Escrow Shares will be released from escrow to the Sponsor (along with any related earnings and proceeds) upon the occurrence of certain Triggering Events described therein prior to December31, 2027.

Note 10 — Fair Value Measurements

Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include:

•        Level1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets;

•        Level2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and

•        Level3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.

As of March31, 2021 and December31, 2020, the aggregate values of the Private Placement Warrants and Public Warrants were approximately $57.4million and $97.2million, respectively, based on the closing price of THBR on that date of $10.42 and $13.22, respectively.

The Warrants are accounted for as liabilities in accordance with ASC 815-40 and are presented within warrant liabilities on the Balance Sheet. The warrant liabilities are measured at fair value at inception and on a recurring basis, with changes in fair value presented within change in fair value of warrant liabilities in the Statement of Operations.

The following table presents information about the Company’s assets and liabilities that are measured at fair value on a recurring basis at March31, 2021 and December31, 2020 and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value:

Description	Level	March 31, 2021		December 31, 2020
Liabilities:
Public Warrants	1	$	37,605,000	$	63,738,750
Private Placement Warrants	2		19,808,500		33,443,044

No other changes in valuation techniques or inputs occurred during the years ended March31, 2021 and December31, 2020. No transfers of assets between Level 1 and Level 2 of the fair value measurement hierarchy occurred during the three months ended March31, 2021.

Thunder Bridge Acquisition II, Ltd.

Opinion on the financial statements

We have audited the accompanying balance sheets of Thunder Bridge Acquisition II, Ltd. (the “Company”) as of December31, 2020 and 2019, the related statements of operations, changes in stockholders’ equity, and cash flows for the year ended December31, 2020 and for the period from February13, 2019 (inception) through December31, 2019 and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December31, 2020 and 2019, and the results of its operations and its cash flows for the year ended December31, 2020 and for the period from February13, 2019 (inception) through December31, 2019, in conformity with accounting principles generally accepted in the United States of America.

Restatement of previously issued financial statements

As discussed in Note10, the 2019 and 2020 financial statements have been restated to correct a misstatement.

Basis for opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 2019.

NOTES TO FINANCIAL STATEMENTS

Note 1 — Organization and Plan of Business Operations

Thunder Bridge Acquisition II, Ltd. (the “Company”) is a newly organized blank check company incorporated as a Cayman Islands exempted company on February13, 2019. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (a “Business Combination”). The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended (the “Securities Act”), as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”).

All activity for the period from February13, 2019 (date of inception) through August13, 2019 relates to the Company’s formation and its initial public offering (the “Initial Public Offering”), which is described in Note 3.

The registration statement for the Initial Public Offering was declared effective on August8, 2019. On August13, 2019 the Company consummated the Initial Public Offering of 34,500,000 units (“Units” and, with respect to the Class A ordinary shares included in the Units offered, the “Public Shares”), generating gross proceeds of $345,000,000, which is described in Note 3.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 8,650,000 warrants (the “Private Placement Warrants”) at a price of $1.00 per warrant in a private placement to Thunder Bridge Acquisition II, LLC (the “Sponsor”), generating gross proceeds of $8,650,000, which is described in Note 4.

Following the closing of the Initial Public Offering, an amount of $345,000,000 ($10.00 per Unit) from the net proceeds of the sale of the units in the Initial Public Offering and the sale of the Private Placement Warrants was placed in a trust account (“Trust Account”) which may be invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 180 days or less or in any open-ended investment company that holds itself out as a money market fund selected by the Company meeting the conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the consummation of a Business Combination or (ii) the distribution of the Trust Account, as described below.

Transaction costs amounted to $19,483,537 consisting of $6,900,000 of underwriting fees, $12,075,000 of deferred underwriting fees (see Note 6) and $508,537 of other costs. In addition, $1,230,680 of cash was held outside of the Trust Account and is available for working capital purposes.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. The Company’s initial Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (excluding any deferred underwriting commissions and taxes payable on the income earned on the Trust Account) at the time of the signing an agreement to enter into a Business Combination. However, the Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act. There is no assurance that the Company will be able to successfully effect a Business Combination.

The Company will provide the holders of the public shares (the “Public Shareholders”) with the opportunity to redeem all or a portion of their public shares upon the completion of the Business Combination, either (i) in connection with a shareholder meeting called to approve the Business Combination or (ii) by means of a tender offer, in either case at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Business Combination, including interest (which interest shall be net of taxes payable) divided by the number of then outstanding public shares. Notwithstanding the foregoing, if the Company seeks shareholder approval of the Business Combination and the Company does not conduct redemptions pursuant to the tender offer rules, a Public Shareholder, together with any affiliate of such shareholder or any other

person with whom such shareholder is acting in concert or as a “group” (as defined in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the public shares. In connection with any shareholder vote required to approve any Business Combination, the Sponsor and any other shareholder of the Company prior to the consummation of the Public Offering (collectively with the Sponsor, the “Initial Shareholders”) and the Company’s directors and officers will agree (i) to vote any of their respective Ordinary Shares (as defined below) in favor of the initial Business Combination and (ii) not to redeem any of their Ordinary Shares in connection therewith. The Company will proceed with a Business Combination only if it has net tangible assets of at least $5,000,001 upon consummation of the Business Combination and, in the case of a shareholder vote, a majority of the outstanding Ordinary Shares voted are voted in favor of the Business Combination.

The NASDAQ rules require that the Business Combination must be with one or more target businesses that together have an aggregate fair market value equal to at least 80% of the balance in the Trust Account (less any Deferred Commissions (as defined below) and taxes payable on interest earned) at the time of the Company signing a definitive agreement in connection with the Business Combination.

The Company will have until August13, 2021 to consummate a Business Combination (the “Combination Period”). If the Company has not completed a Business Combination within 24months of the closing of the Initial Public Offering, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable, and less up to $100,000 of interest to pay dissolution expenses) divided by the number of then outstanding public shares, which redemption will completely extinguish the rights of the Public Shareholders as shareholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and its Board of Directors, dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. In the event of a liquidation, the Public Shareholders will be entitled to receive a full pro rata interest in the Trust Account (initially anticipated to be approximately $10.00 per share, plus any pro rata interest earned on the Trust Fund not previously released to the Company and less up to $100,000 of interest to pay dissolution expenses). There will be no redemption rights or liquidating distributions with respect to the Founder Shares (as defined below) or the Private Placement Warrants, which will expire worthless if the Company fails to complete a Business Combination within the 24-month time period.

Basis of Presentation

The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) and pursuant to the accounting and disclosure rules and regulations of the U.S. Securities and Exchange Commission.

Loss Per Ordinary Share (Restated)

Basic loss per ordinary share is computed by dividing net income (loss) applicable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period. Consistent with FASB 480, ordinary shares subject to possible redemption, as well as their pro rata share of undistributed trust earnings consistent with the two-class method, have been excluded from the calculation of loss per ordinary share for the year ended December31, 2020 and for the period from February13, 2019 (date of inception) through December31, 2019. Such shares, if redeemed, only participate in their pro rata share of trust earnings. Diluted loss per share includes the incremental number of ordinary shares to be issued to settle warrants, as calculated using the treasury method. For the year ended

Note 2 — Significant Accounting Policies(cont.)

December31, 2020 and for the period from February13, 2019 (date of inception) through December31, 2019, the Company did not have any dilutive warrants, securities or other contracts that could potentially, be exercised or converted into ordinary shares. As a result, diluted loss per ordinary share is the same as basic loss per ordinary share for all periods presented.

A reconciliation of net loss per ordinary share as adjusted for the portion of income that is attributable to ordinary shares subject to redemption is as follows:

	For the Year Ended December 31, 2020 (Restated)			For the Period from February 13, 2019 (Date of Inception) through December 31, 2019 (Restated)
Net (loss) income	$	(73,292,930	)	$	3,619,908
Less: Income attributable to ordinary shares		(2,122,286	)		(2,460,851	)
Net (loss) income available to ordinary shares	$	(75,415,216	)	$	1,159,057
Weighted average shares outstanding, basic and diluted		8,625,000			8,437,500
Basic and diluted net loss per ordinary share	$	(8.74	)	$	0.14

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents are carried at cost, which approximates fair value.

Use of Estimates

The preparation of financial statements in conformity with US 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 date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates.

Ordinary shares subject to possible redemption

The Company accounts for its ordinary shares subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Ordinary shares subject to mandatory redemption (if any) is classified as a liability instrument and is measured at fair value. Conditionally redeemable ordinary shares (including ordinary shares that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) is classified as temporary equity. At all other times, ordinary shares is classified as shareholders’ equity. The Company’s ordinary shares features certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, at December31, 2020 and 2019, ordinary shares subject to possible redemption is presented as temporary equity, outside of the shareholders’ equity section of the Company’s balance sheet.

Offering costs (restated)

Offering costs consist of legal, accounting, underwriting fees and other costs incurred through the balance sheet date that are directly related to our initial public offering. Offering costs amounting to $19,483,537, of which $18,509,360 were charged to shareholders’ equity upon the completion of our initial public offering, with the balance expensed as a cost of the warrant liability.

Income Taxes

The Company accounts for income taxes under FASB ASC 740, Income Taxes (“ASC 740”). ASC 740 requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the financial statement and tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carry forwards. ASC 740 additionally requires a valuation allowance to be established when it is more likely than not that all or a portion of deferred tax assets will not be realized.

ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits as of December31, 2019. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position.

There is currently no taxation imposed on income by the Government of the Cayman Islands.

Recent Accounting Pronouncements

Management does not believe that any other recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying financial statements.

Emerging Growth Company

Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which at times, may exceed the Federal depository insurance coverage of $250,000. The Company has not experienced losses on these accounts.

Financial Instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB ASC 820, Fair Value Measurements and Disclosures, approximates the carrying amounts represented in the financial statements.

Fair Value Measurements (restated)

Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include:

•        Level1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets;

•        Level2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and

•        Level3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.

Derivative Financial Instruments

The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, “Derivatives and Hedging”. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued at each reporting date, with changes in the fair value reported in the statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the balance sheet as current or non-current based on whether or not net-cash settlement or conversion of the instrument could be required within 12months of the balance sheet date.

Subsequent Events

Management of the Company evaluates events that have occurred after the balance sheet date of December31, 2020 through the date these financial statements were issued. Based upon the review, management did not identify any recognized or non-recognized subsequent events that would have required adjustment or disclosure in the financial statements.

Note 3 — Initial Public Offering

Pursuant to the Initial Public Offering, the Company sold 34,500,000 Units at a purchase price of $10.00 per Unit. Each Unit consists of one Class A Share and one-half redeemable Warrant. Each whole warrant (“Public Warrant”) entitles the holder to purchase one Class A Share at a price of $11.50 per share (See Note 7).

Note 4 — Private Placement

Simultaneously with the Initial Public Offering, the Sponsor purchased an aggregate of 8,650,000 Private Placement Warrants at $1.00 per Private Placement Warrant, for an aggregate purchase price of $8,650,000. Each Private Placement Warrant is exercisable to purchase one share of Class A ordinary shares at an exercise price of $11.50. The proceeds from the Private Placement Warrants were added to the proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the proceeds of the sale of the Private Placement Warrants will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law) and the Private Placement Warrants will expire worthless. There will be no redemption rights or liquidating distributions from the Trust Account with respect to the Private Placement Warrants.

The Private Placement Warrants are identical to the Public Warrants underlying the Units sold in the Initial Public Offering, except that the Private Placement Warrants: (i) will not be redeemable by the Company; (ii) may be exercised for cash or on a cashless basis, so long as they are held by the Sponsor or any of its permitted transferees and (iii) are (including the ordinary shares issuable upon exercise of the Private Placement Warrants) entitled to registration rights. Additionally, the Sponsor has agreed not to transfer, assign or sell any of the Private Placement Warrants, including the Class A Shares issuable upon exercise of the Private Placement Warrants (except to certain permitted transferees), until 30 days after the completion of the Business Combination.

Note 5 — Related Party Transactions

Founder Shares

On February19, 2019, an aggregate 8,625,000 Class B Shares (the “Founder Shares”) were sold to the Sponsor at a price of approximately $0.003 per share, for an aggregate price of $25,000. This number included an aggregate of up to 1,125,000 Founder Shares that were subject to forfeiture if the over-allotment option is not exercised in full by the Underwriters in order to maintain the Initial Shareholders’ ownership at 20% of the issued and outstanding Ordinary Shares upon completion of the Initial Public Offering. The Underwriters exercised their over-allotment option in full so none of the Founder Shares were forfeited. The Founder Shares are identical to the Class A Shares included in the Units being sold in the Initial Public Offering, except that the Founder Shares (i) have the voting rights described in Note7, (ii) are subject to certain transfer restrictions described below and (iii) are convertible into Class A Shares on a one-for-one basis, subject to adjustment pursuant to the anti-dilution provisions contained therein. The Founder Shares may not be transferred, assigned or sold until the earlier of (i) one year after the completion of the Business Combination and (ii) the date on which the Company completes a liquidation, merger, share exchange, reorganization or other similar transaction after the Business Combination that results in all of the Public Shareholders having the right to exchange their Class A Shares for cash, securities or other property. Notwithstanding the foregoing, if the last sale price of the Class A Shares equals or exceeds $12.00 per share (as adjusted for share splits, share dividends, rights issuances, subdivisions, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Business Combination, the Founder Shares will be released from the lock-up.

Private Placement Warrants

The sponsor purchased from the Company an aggregate of 8,650,000 Private Placement Warrants at $1.00 per Private Placement Warrant, for an aggregate purchase price of $8,650,000.

Administrative Services Agreement

The Company entered into an agreement whereby, commencing on August8, 2019 through the earlier of the consummation of a Business Combination or the Company’s liquidation, the Company will pay an affiliate of the sponsor a monthly fee of $10,000 for office space, utilities and administrative support. As of December31, 2020 and 2019, the Company had incurred and paid $120,000 and $50,000, respectively.

Advisory Agreement

The Company entered into an agreement, whereby, commencing on August8, 2019 through the earlier of the consummation of a Business Combination or the Company’s liquidation, the Company will pay an affiliate of Chief Executive Officer and its senior special advisor a monthly fee of $20,000 for advisory services related to its search for and consummation of its Initial Business Combination. As of December31, 2020 and 2019, the Company had incurred and paid $240,00 and $100,000, respectively.

Related Party Loans

In order to finance transaction costs in connection with the Business Combination, the Sponsor or an affiliate of the Sponsor or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes the Business Combination, the Company would repay such loaned amounts. In the event that the Business Combination does not close, the Company may use a portion of the working capital held outside the trust account to repay such loaned amounts but no proceeds from the trust account would be used for such repayment. Up to $1,500,000 of such loans may be convertible into warrants at a price of $1.00 per warrant at the option of the lender. The warrants would be identical to the private placement warrants issued to the Sponsor. The terms of such loans by the Company’s officers and directors, if any, have not been determined and no written agreements exist with respect to such loans. The Company does not expect to seek loans from parties other than the Sponsor or its directors or officers or their respective affiliates as it does not believe third parties will be willing to loan such funds and provide a waiver against any and all rights to seek access to funds in the trust account. There was $300,000 and $0 of related party loans outstanding as of December31, 2020 and 2019, respectively.

Financing Agreement

The Company and a member of the Sponsor entered into a letter agreement on August8, 2019, under the terms of which the Company will provide such member with a right of first refusal to provide up to 51% of any necessary debt financing in connection with the Company’s Business Combination and to act as lead agent and arranger in connection thereto.

Note Payable to Sponsor

On February20, 2019, the Sponsor and the Company executed an unsecured promissory note pursuant to which the Company may borrow up to $300,000 in the aggregate to cover the Initial Public Offering (the “Promissory Note”). The Promissory Note was non-interest bearing and payable on the earlier of December31, 2019 or the completion of the Initial Public Offering. On August13, 2019, the outstanding balance of $277,000 in borrowings outstanding under the Promissory Note was repaid.

Note 6 — Commitments

Registration Rights

Pursuant to a registration rights agreement entered into on August8, 2019, the holders of the Founder Shares, Private Placement Warrants (and their underlying securities) and the warrants that may be issued upon conversion of the Working Capital Loans (and their underlying securities) are entitled to registration rights. The holders of a majority of these securities are entitled to make up to three demands, excluding short form demands, that the Company register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of a Business Combination and rights to require the Company to register for resale such securities pursuant to Rule 415 under the Securities Act. However, the registration rights agreement provides that the Company will not permit any registration statement filed under the Securities Act to become effective until termination of the applicable lock-up period. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriters Agreement

The Company granted the underwriters a 45-day option to purchase up to 4,500,000 additional Units to cover over-allotments at the Initial Public Offering price, less the underwriting discounts and commissions, which was exercised on August13, 2019.

The underwriters were paid a cash underwriting discount of 2.0% of the gross proceeds of the Initial Public Offering, or $6,900,000. In addition, the underwriters are entitled to a deferred underwriting discount of 3.5% of the gross proceeds of the Initial Public Offering, or $12,075,000. The deferred commission was placed in the Trust Account and will be paid in cash upon the closing of a Business Combination, subject to the terms of the underwriting agreement.

Note 7 — Warrant Liability (Restated)

Public Warrants may only be exercised for a whole number of shares. No fractional warrants will be issued upon separation of the Units and only whole warrants will trade. The Public Warrants will become exercisable on the later of (a) 30 days after the completion of a Business Combination or (b) 12months from the closing of the Initial Public Offering. The Public Warrants will expire five years after the completion of a Business Combination or earlier upon redemption or liquidation.

The Company is not obligated to deliver any Class A ordinary shares pursuant to the exercise of a warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act with respect to the Class A ordinary shares underlying the warrants is then effective and a prospectus relating thereto is current, subject to the Company satisfying its obligations with respect to registration. No warrant will be exercisable and the Company will not be obligated to issue any Class A ordinary shares upon exercise of a warrant unless Class A ordinary shares issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants.

The Company has agreed that as soon as practicable, but in no event later than 15 business days, after the closing of a Business Combination, the Company will use its best efforts to file, and within 60 business days following a Business Combination to have declared effective, a registration statement covering the Class A ordinary shares issuable upon exercise of the warrants. The Company will use its reasonable best efforts to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the warrants in accordance

F-96

THUNDER BRIDGE ACQUISITION II, LTD.
NOTES TO FINANCIAL STATEMENTS

Note 7 — Warrant Liability (Restated)(cont.)

with the provisions of the warrant agreement. Notwithstanding the above, if the Class A ordinary shares at the time of any exercise of a warrant not listed on a national securities exchange such that it satisfies the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, the Company will not be required to file or maintain in effect a registration statement, but will be required to use its best efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available.

Redemptions of Warrants — Once the warrants become exercisable, the Company may redeem the Public Warrants:

•        in whole and not in part;

•        at a price of $0.01 per warrant;

•        upon not less than 30 days’ prior written notice of redemption to each warrant holder; and

•        if, and only if, the reported last sale price of the Company’s Class A ordinary shares equals or exceeds $18.00 per share for any 20 trading days within a 30-trading day period ending three business days before the Company sends the notice of redemption to each warrant holder.

If and when the warrants become redeemable by the Company, the Company may exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state securities laws.

If the Company calls the Public Warrants for redemption, management will have the option to require all holders that wish to exercise the Public Warrants to do so on a “cashless basis,” as described in the warrant agreement. The exercise price and number of shares of Class A ordinary shares issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, or recapitalization, reorganization, merger or consolidation. However, the warrants will not be adjusted for issuance of Class A ordinary shares at a price below its exercise price. Additionally, in no event will the Company be required to net cash settle the warrants. If the Company is unable to complete a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of warrants will not receive any of such funds with respect to their warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with the respect to such warrants. Accordingly, the warrants may expire worthless.

In addition, if the Company issues additional ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of a Business Combination at a newly issued price of less than $9.20 per ordinary share (with such issue price or effective issue price to be determined in good faith by the Company’s board of directors, and in the case of any such issuance to the sponsor or its affiliates, without taking into account any Founder Shares held by the sponsor or such affiliates, as applicable, prior to such issuance), the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the newly issued price and the redemption price of the warrants shall be adjusted to equal 180% of the newly issued price.

The Private Placement Warrants are identical to the Public Warrants underlying the Units sold in the Initial Public Offering, except that the Private Placement Warrants and the Class A ordinary shares issuable upon the exercise of the Private Placement Warrants will not be transferable, assignable or saleable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Placement Warrants will be exercisable on a cashless basis and be non-redeemable so long as they are held by the initial purchasers or their permitted transferees. If the Private Placement Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants.

At December31, 2020 and 2019, there were 17,250,000 whole public warrants and 8,650,000 private placement warrants outstanding, respectively, with a fair value of $97,181,794 and $23,387,415, respectively.

Note 7 — Warrant Liability (Restated)(cont.)

The Company accounts for the 17,250,000 warrants issued in connection with the Initial Public Offering and the 8,650,000 Private Placement Warrants in accordance with the guidance contained in ASC 815-40. Such guidance provides that because the warrants do not meet the criteria for equity treatment thereunder, each warrant must be recorded as a liability. The warrant agreement contains an Alternative Issuance provision that if less than 70% of the consideration receivable by the holders of the Class A common stock in the Business Combination is payable in the form of common equity in the successor entity, and if the holders of the warrants properly exercises the warrants within thirty days following the public disclosure of the consummation of Business Combination by the Company, the warrant price shall be reduced by an amount equal to the difference (but in no event less than zero) of (i) the warrant price in effect prior to such reduction minus (ii) (A) the Per Share Consideration (as defined below) minus (B) the Black-Scholes Warrant Value (as defined below). The “Black-Scholes Warrant Value” means the value of a Warrant immediately prior to the consummation of the Business Combination based on the Black-Scholes Warrant Model for a Capped American Call on Bloomberg Financial Markets. “Per Share Consideration” means (i) if the consideration paid to holders of the common stock consists exclusively of cash, the amount of such cash per common stock, and (ii) in all other cases, the volume weighted average price of the common stock as reported during the ten-trading day period ending on the trading day prior to the effective date of the Business Combination.

The Company believes that the adjustments to the exercise price of the warrants is based on a variable that is not an input to the fair value of a “fixed-for-fixed” option as defined under FASB ASC Topic No. 815 –40, and thus the warrants are not eligible for an exception from derivative accounting. The accounting treatment of derivative financial instruments requires that the Company record a derivative liability upon the closing of the Proposed Public Offering. Accordingly, the Company will classify each warrant as a liability at its fair value and the warrants will be allocated a portion of the proceeds from the issuance of the Units equal to its fair value determined by the Monte Carlo simulation. This liability is subject to re-measurement at each balance sheet date. With each such remeasurement, the warrant liability will be adjusted to fair value, with the change in fair value recognized in the Company’s statement of operations. The Company will reassess the classification at each balance sheet date. If the classification changes as a result of events during the period, the warrants will be reclassified as of the date of the event that causes the reclassification.

Note 8 — Shareholders’ Equity (Restated)

Preferred Shares

The Company is authorized to issue 1,000,000 preferred shares with a par value of $0.0001. The Company’s board of directors will be authorized to fix the voting rights, if any, designations, powers, preferences, the relative, participating, optional or other special rights and any qualifications, limitations and restrictions thereof, applicable to the shares of each series. The board of directors will be able to, without shareholder approval, issue preferred shares with voting and other rights that could adversely affect the voting power and other rights of the holders of the Ordinary Shares and could have anti-takeover effects.

At December31, 2020 and 2019, there were no preferred shares issued or outstanding.

Ordinary Shares

The Company is authorized to issue 200,000,000 Class A Shares, with a par value of $0.0001 each, and 20,000,000 Class B ordinary shares, with a par value of $0.0001 each (the “Class B Shares” and, together with the Class A Shares, the “Ordinary Shares”). Holders of the Ordinary Shares are entitled to one vote for each Ordinary Share; provided that only holders of the Class B Shares have the right to vote on the election of directors prior to the Business Combination. The Class B Shares will automatically convert into Class A Shares at the time of the Business Combination, on a one-for-one basis, subject to adjustment for share splits, share dividends, rights issuances, subdivisions, reorganizations, recapitalizations and the like, and subject to further adjustment as provided herein. In the case that additional Class A Shares, or equity-linked securities, are issued or deemed issued in excess of the amounts sold in the Initial Public Offering and related to the closing of the Business Combination, the ratio at which the Class B Shares shall convert into Class A Shares will be adjusted (unless the holders of a majority

of the outstanding Class B ordinary shares agree to waive such anti-dilution adjustment with respect to any such issuance or deemed issuance) so that the number of Class A Shares issuable upon conversion of all Class B Shares will equal, in the aggregate, 20% of the sum of all Ordinary Shares outstanding upon completion of the Initial Public Offering plus all Class A Shares and equity-linked securities issued or deemed issued in connection with the Business Combination, excluding any Ordinary Shares or equity-linked securities issued, or to be issued, to any seller in the Business Combination, or any Private Placement-equivalent Warrants issued to the Sponsor or its affiliates upon conversion of loans made to the Company. Holders of Founder Shares may also elect to convert their Class B Shares into an equal number of Class A Shares, subject to adjustment as provided above, at any time.

At December31, 2020 and 2019, there were 0 and 0 Class A Shares issued and outstanding, (excluding 34,500,000 and 34,500,000 Class A shares subject to possible redemption), and there were 8,625,000 Class B Shares issued and outstanding, respectively.

Founder Shares

On February20, 2019, an aggregate of 8,625,000 Class B Shares (the “Founder Shares”) were sold to the Sponsor at a price of approximately $0.003 per share, for an aggregate price of $25,000. This number included an aggregate of up to 1,125,000 Founder Shares that were subject to forfeiture if the over-allotment option is not exercised in full by the Underwriters in order to maintain the Initial Shareholders’ ownership at 20% of the issued and outstanding Ordinary Shares upon completion of the Initial Public Offering. The Founder Shares are identical to the Class A Shares included in the Units sold in the Initial Public Offering, except (i) they have the voting rights described in this Note7, (ii) they are subject to certain transfer restrictions described below and (iii) they are convertible into Class A Shares on a one-for-one basis, subject to adjustment pursuant to the anti-dilution provisions contained therein. The Founder Shares may not be transferred, assigned or sold until the earlier of (i) one year after the completion of the Business Combination and (ii) the date on which the Company completes a liquidation, merger, share exchange, reorganization or other similar transaction after the Business Combination that results in all of the Public Shareholders having the right to exchange their Class A Shares for cash, securities or other property.

Notwithstanding the foregoing, if the last sale price of the Class A Shares equals or exceeds $12.00 per share (as adjusted for share splits, share dividends, rights issuances, subdivisions, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Business Combination, the Founder Shares will be released from the lock-up.

Note 9 — Business Combination

On December14, 2020, The Company (including its successor after the Domestication (as defined below), “Thunder Bridge II”), entered into a Master Transactions Agreement (the “MTA”) with Thunder Bridge II Surviving Pubco, Inc., a Delaware corporation (“Surviving Pubco”), TBII Merger Sub Inc., a Delaware corporation and wholly-owned subsidiary of Surviving Pubco (“TBII Merger Sub”), ADK Merger Sub LLC, a Delaware limited liability company and wholly owned subsidiary of Surviving Pubco (“ADK Merger Sub”), ADK Service Provider Merger Sub LLC, a Delaware limited liability company and wholly owned subsidiary of Surviving Pubco (“ADK Service Provider Merger Sub”), ADK Blocker Merger Sub LLC, a Delaware limited liability company and wholly owned subsidiary of Surviving Pubco (“ADK Blocker Merger Sub” and collectively with the TBII Merger Sub, ADK Merger Sub and ADK Service Provider Merger Sub, the “Merger Subs”), Ay Dee Kay LLC, d/b/a indie Semiconductor, a California limited liability company (the “Company”), the corporate entities listed therein holding membership unites in the Company (the “ADK Blockers”), ADK Service Provider Holdco LLC, a Delaware limited liability company (“ADK Service Provider Holdco”), and solely in his capacity as Company Securityholder Representative, Donald McClymont (the “Company Securityholder Representative”). Pursuant to the MTA, subject to the terms and conditions set forth therein, upon the closing of the transactions contemplated thereby (the “Closing”): (i) Thunder Bridge II will domesticate into a Delaware corporation (the “Domestication”), (ii) TBII Merger Sub will merge with and into Thunder Bridge II (the “Thunder Bridge II Merger”) with Thunder Bridge II being the surviving corporation and pursuant to which Thunder Bridge II equity holders will receive corresponding shares in Surviving Pubco, (iii) ADK Merger Sub will merge with and into the Company (the “Company Merger”)

Note 9 — Business Combination(cont.)

with the Company being the surviving limited liability company (in such capacity after the Company Merger, the “Surviving Company”), (iv) the ADK Blockers will merge with and into ADK Blocker Merger Sub, with ADK Blocker Merger Sub being the surviving limited liability company (the “Blocker Mergers,”) and (v) ADK Service Provider Merger Sub will merge with and into ADK Service Provider Holdco, with ADK Service Provider Holdco being the surviving limited liability company (“Service Provider Merger,” and collectively with the Thunder Bridge II Merger, the Company Merger and the Blocker Mergers, the “Mergers,” and the Mergers collectively with the other transactions contemplated by the Merger Agreement, the “Transactions”). Following the Mergers, Surviving Pubco will be the successor issuer and public company pursuant to the federal securities laws, and Surviving Pubco’s corporate name will change to “indie Semiconductor, Inc.”

As a result of the Transactions, each issued and outstanding Class A ordinary share and Class B ordinary share of Thunder Bridge II will convert into a share of Class A common stock of Surviving Pubco, and each issued and outstanding warrant to purchase Class A ordinary shares of Thunder Bridge II will be exercisable by its terms to purchase an equal number of shares of Class A common stock of Surviving Pubco. Each share of Surviving Pubco Class A common stock will provide the holder with the rights to vote, receive dividends, share in distributions in connection with a liquidation and other stockholder rights with respect to Surviving Pubco.

Merger Consideration

The merger consideration (the “Merger Consideration”) to be paid to holders of the limited liability company interests of the Company (collectively, the “Company Equity Holders”) pursuant to the MTA will be an amount equal to 90,000,000shares of Class A common stock of Thunder Bridge II, subject to adjustment as described below, paid in either shares of Class A common stock of Surviving Pubco or limited liability company interests in the Company (valued at $10.00 per unit) (the “Post-Merger Company Units”), which will be exchangeable on a one-for-one basis for shares of Class A common stock of Surviving Pubco. The Merger Consideration is subject to adjustment downward for the amount that Company indebtedness exceeds Company indebtedness at closing. In addition, Company Equity Holders will receive the right to receive the Earn Out Shares described below, if any.

Those Company Equity Holders that receive Post-Merger Company Units will also receive one share of Class V common stock of Surviving Pubco, which will have no economic rights in Surviving Pubco but will entitle the holder to vote as a stockholder of Surviving Pubco, with the number of votes equal to the number of Post-Merger Company Units held by the Company Equity Holder. After the Closing, each Company Equity Holder will be permitted to exchange its Post-Merger Company Unit for a share of Class A common stock of Surviving Pubco on a one-for-one basis.

The Earn Out

In addition to the consideration set forth above, the Company Equity Holders will also have a contingent earn out right to receive up to an additional 10,000,000shares of Class A common stock of Surviving Pubco (the “Earn Out Shares”) after the Closing based on the following:

•        If at any time following the Closing and prior to December31, 2027, the volume weighted average price of the Class A common stock of Surviving Pubco is greater than or equal to $12.50 over any 20 trading days within any 30 trading day period, the Company Equity Holders will be entitled to receive 50% of the Earn Out Shares; and

•        If at any time following the Closing and prior to December31, 2027, the volume weighted average price of the Class A common stock is greater than or equal to $15.00 over any 20 trading days within any 30 trading day period, the Company Equity Holders will be entitled to receive 100% of the remaining unissued Earn Out Shares.

Payments of the Earn Out Shares to holders of Class A common stock of the Surviving Pubco or holders of the Post-Merger Company Units will not depend on the holders continuing to hold the holders’ Class A common stock or Units, as the case may be, at the time of the payout of the Earn Out Shares.

F-100

THUNDER BRIDGE ACQUISITION II, LTD.
NOTES TO FINANCIAL STATEMENTS

Note 9 — Business Combination(cont.)

The Earn Out Shares will be paid either in shares of Class A common stock of the Surviving Pubco, or in Post-Merger Company Units, valued at the applicable price target stated above. Holders of Class A common stock of the Surviving Pubco will be paid the Earn Out Shares in additional shares of Class A common stock of the Surviving Pubco. Holders of Post-Merger Company Units will be paid the Earn Out Shares in additional Post-Merger Company Units.

The price targets shall be equitably adjusted for stock splits, dividends, reorganizations, combinations, recapitalizations and similar transactions affecting the shares of Class A common stock of Surviving Pubco.

Notwithstanding the foregoing, if there is a Surviving Pubco Sale (as defined in the MTA) at any time following the Closing and prior to December31, 2027, then all of the remaining unissued Earn Out Shares will be deemed to be earned and will paid out to the Company Equity Holders.

Covenants of the Parties

Note 9 — Business Combination(cont.)

If the MTA is terminated, all further obligations of the parties under the MTA will terminate and will be of no further force and effect (except that certain obligations related to public announcements, confidentiality, termination, fees and expenses, waiver of claims against the trust, and certain general provisions will continue in effect), and no party will have any further liability to any other party thereto except for liability for any fraud claims or willful and intentional breach of the MTA prior to such termination.

The foregoing description of the MTA and the Transactions do not purport to be complete and are qualified in their entirety by the terms and conditions of the MTA, a copy of which is filed as Exhibit 2.1 hereto and incorporated herein by reference.

The MTA contains representations, warranties and covenants that the respective parties made to each other as of the date of such agreement or other specific dates. The assertions embodied in those representations, warranties and covenants were made for purposes of the contract among the respective parties and are subject to important qualifications and limitations agreed to by the parties in connection with negotiating such agreement. The MTA has been filed to provide investors with information regarding its terms. It is not intended to provide any other factual information about Thunder Bridge II, the Company or any other party to the MTA. In particular, the representations, warranties, covenants and agreements contained in the MTA, which were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to the MTA, may be subject to limitations agreed upon by the contracting parties (including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the MTA instead of establishing these matters as facts) and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors and reports and documents filed with the SEC. Investors should not rely on the representations, warranties, covenants and agreements, or any descriptions thereof, as characterizations of the actual state of facts or condition of any party to the MTA. In addition, the representations, warranties, covenants and agreements and other terms of the MTA may be subject to subsequent waiver or modification. Moreover, information concerning the subject matter of the representations and warranties and other terms may change after the date of the MTA, which subsequent information may or may not be fully reflected in Thunder Bridge II’s public disclosures.

Subscription Agreements

Contemporaneously with the execution of the MTA, Thunder Bridge II entered into separate Subscription Agreements with a number of subscribers (each a “Subscriber”), pursuant to which the Subscribers agreed to purchase, and Thunder Bridge II agreed to sell to the Subscribers, an aggregate of up to 15,000,000shares of Class A common stock of Thunder Bridge II (the “PIPE Shares”), in a private placement for a purchase price of $10.00 per share and an aggregate purchase price of $150million (the “PIPE Investments”).

The closing of the sale of the PIPE Shares pursuant to the Subscription Agreements is contingent upon, among other customary closing conditions, the substantially concurrent Closing of the Transactions. The purpose of the PIPE Investments is to raise additional capital for use by the Company following the Closing.

Pursuant to the Subscription Agreements, Thunder Bridge II agreed that, within 30 calendar days after the Closing, Thunder Bridge II (or its successor) will file with the SEC (at Thunder Bridge II’s sole cost and expense) a registration statement registering the resale of the PIPE Shares, and Thunder Bridge II shall use its commercially reasonable efforts to have such registration statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) the 90th calendar day (or 120th calendar day if the SEC notifies Thunder Bridge II that it will “review” the registration statement) following the Closing and (ii) the fifth business day after the date Thunder Bridge II is notified (orally or in writing, whichever is earlier) by the SEC that the registration statement will not be “reviewed” or will not be subject to further review.

The foregoing description of the Subscription Agreements does not purport to be complete and is qualified in its entirety by the terms and conditions of the Subscription Agreements, a form of which is filed as Exhibit 10.1 hereto, and is incorporated herein by reference.

Exchange Agreement

Concurrently with the completion of the Mergers, Surviving Pubco will enter into an exchange agreement with the Company and the Company Equity Holders receiving Post-Merger Company Units (the “Exchange Agreement”), which will provide for the exchange of Post-Merger Company Units into shares of Class A common stock of the Surviving Pubco. Holders of Post-Merger Company Units will, from and after the six-month anniversary of the Closing, be able to elect to exchange all or any portion of their Post-Merger Company Units for shares of Class A common stock by delivering a notice to the Surviving Pubco; provided, that Thunder Bridge II, at its sole election, may instead pay for such Post-Merger Company Units in cash based on the volume weighted average price of the Class A common stock. The initial exchange ratio will be one Post-Merger Company Unit for one share of Class A common stock, subject to certain adjustments.

The foregoing description of the Exchange Agreement does not purport to be complete and is qualified in its entirety by the terms and conditions of the Exchange Agreement, a copy of which is filed as Exhibit 10.2 hereto and is incorporated herein by reference.

Tax Receivable Agreement

Concurrently with the completion of the Transactions and as a condition precedent for the Closing, the Surviving Pubco will enter into the tax receivable agreement (the “Tax Receivable Agreement”) with certain holders of the Post-Merger Company Units (the “TRA Participants”). Pursuant to the Tax Receivable Agreement, the Surviving Pubco will be required to pay the TRA Participants 85% of the amount of savings, if any, in U.S. federal, state and local income tax that the Surviving Pubco actually realizes as a result of (i) the increases in tax basis of the Surviving Company’s assets attributable to and resulting from any exchanges of Post-Merger Company Units for Class A common stock of Surviving Pubco and (ii) certain net operating loss carryforwards of the ADK Blockers inherited by Surviving Pubco in connection with the Transactions. All such payments to the TRA Participants will be the Surviving Pubco’s obligation, and not that of the Company.

The foregoing description of the Tax Receivable Agreement does not purport to be complete and is qualified in its entirety by the terms and conditions of the Tax Receivable Agreement, a copy of which is filed as Exhibit 10.3 hereto and is incorporated herein by reference.

In the Support Agreements for the officers and directors of the Company and certain Company Equity Holders, they each agreed to vote all of their Company membership interests in favor of the MTA and related transactions and to take certain other actions in support of the MTA and related transactions. The Support Agreements also prevent them from transferring their voting rights with respect to their Company membership interests or otherwise transferring their Company membership interests prior to the meeting of the Company’s members to approve the MTA and related transactions, except for certain permitted transfers.

In its Support Agreement, the Sponsor agreed with the Company to vote all of its equity interests in Thunder Bridge II in favor of the MTA and related transactions and to take certain other actions in support of the MTA and related transactions.

Note 10 — Restatement of Previously Issued Financial Statements

On April12, 2021, the Acting Director of the Division of Corporation Finance and Acting Chief Accountant of the Securities and Exchange Commission together issued a statement regarding the accounting and reporting considerations for warrants issued by special purpose acquisition companies entitled “Staff Statement on Accounting and Reporting Considerations for Warrants Issued by Special Purpose Acquisition Companies (“SPACs”)” (the “SEC Statement”). Specifically, the SEC Statement focused on certain settlement terms and provisions related to certain tender offers following a business combination, which terms are similar to those contained in the warrant agreement, dated as of August8, 2019, between the Company and Continental Stock Transfer & Trust Company, a New York corporation, as warrant agent (the “Warrant Agreement”). As a result of the SEC Statement, the Company reevaluated the accounting treatment of (i) the 17,250,000 redeemable warrants (the “Public Warrants”) that were included in the units issued by the Company in its initial public offering (the “IPO”) and (ii) the 8,650,000 redeemable warrants that were issued to the Company’s sponsor in a private placement that closed concurrently with the closing of the IPO (the “Private Placement Warrants” and, together with the Public Warrants, the “Warrants”, which are discussed in Note3, Note4, Note 5 and Note 7). The Company previously accounted for the Warrants as components of equity.

In further consideration of the guidance in Accounting Standards Codification (“ASC”) 815-40, Derivatives and Hedging — Contracts in Entity’s Own Equity, the Company concluded that a provision in the Warrant Agreement related to certain tender or exchange offers precludes the Warrants from being accounted for as components of equity. As the Warrants meet the definition of a derivative as contemplated in ASC 815, the Warrants should be recorded as derivative liabilities on the Balance Sheet and measured at fair value at inception (on the date of the IPO) and at each reporting date in accordance with ASC 820, Fair Value Measurement, with changes in fair value recognized in the Statement of Operations in the period of change.

The Company’s management and the audit committee of the Company’s Board of Directors concluded that it is appropriate to restate the Company’s previously issued audited financial statements as of December31, 2020 and for the period from February13, 2019 (date of inception) through December31, 2019, as previously reported in its Form 10-K. The restated classification and reported values of the Warrants as accounted for under ASC 815-40 are included in the financial statements herein.

Note 11 — Fair Value Measurements

The following table presents information about the Company’s assets and liabilities that are measured at fair value on a recurring basis at December31, 2020 and 2019, and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value:

		December 31,
Description	Level	2020		2019
Liabilities:
Private Placement Warrants(1)	2	$	33,443,044	$	7,862,415
Public Warrants(1)	1	$	63,738,750	$	15,525,000

____________

(1)      Measured at fair value on a recurring basis.

Warrants

The Warrants are accounted for as liabilities in accordance with ASC 815-40 and are presented within warrant liabilities on the Balance Sheet. The warrant liabilities are measured at fair value at inception and on a recurring basis, with changes in fair value presented within change in fair value of warrant liabilities in the Statement of Operations.

Initial Measurement

The Company established the initial fair value for the Warrants on August9, 2019, the date of the Company’s Initial Public Offering, using a Monte Carlo simulation model for the Private Placement Warrants and the Public Warrants. The Company allocated the proceeds received from (i) the sale of Units (which is inclusive of one share of Class A ordinary shares and one-half of one Public Warrant), and (ii) the sale of Private Placement Warrants, first to the Warrants based on their fair values as determined at initial measurement, with the remaining proceeds allocated to Class A ordinary shares subject to possible redemption based on their relative fair values at the initial measurement date. The Warrants were classified as Level 3 at the initial measurement date due to the use of unobservable inputs.

The key inputs into the Monte Carlo simulation model for the Private Placement Warrants and Public Warrants were as follows at initial measurement:

Input	August 9, 2019
Risk-free interest rate		1.64	%
Expected term (years)		6.72
Expected Volatility		14	%
Exercise Price	$	11.50

The Company’s use of a Monte Carlo simulation model required the use of subjective assumptions:

•        The risk-free interest rate assumption was based on the 6.72 year yield the yield on the U.S. Treasury notes as of the Valuation Date that matched the time period to de-SPAC as of each Valuation Date.

•        The expected term was simulated out daily over the expected remaining life of the Public Warrants. The specific remaining life was based on Management’s estimated time to de-SPAC as well as the five-year contractual period that begins once the transaction closes.

•        The expected volatility assumption was based on the implied volatility from a set of comparable publicly-traded warrants as determined based on the size and proximity of other similar business combinations. An increase in the expected volatility, in isolation, would result in an increase in the fair value measurement of the warrant liabilities and vice versa.

Note 11 — Fair Value Measurements (cont.)

•        The fair value of the Units, which each consist of one Class A ordinary share and one-half of one Public Warrant, represents the closing price on the measurement date as observed from the ticker THBR. Based on the applied volatility assumption and the expected term to a business combination noted above, the Company determined that the risk neutral probability of exceeding the $18.00 redemption value by the start of the exercise period for the Warrants resulted in a nominal difference in value between the Public Warrants and Private Placement Warrants across the valuation dates utilized in the Monte Carlo simulation model.

Therefore, the resulting valuations for the two classes of Warrants were determined to be equal. On August9, 2019, the Private Placement Warrants and Public Warrants were determined to be $1.57 per warrant for aggregate values of $12.6million and $31.6million, respectively.

Subsequent Measurement

The Warrants are measured at fair value on a recurring basis. The subsequent measurement of the Public Warrants as of December31, 2020 is classified as Level 1 due to the use of an observable market quote in an active market under the ticker THBR. As the transfer of Private Placement Warrants to anyone outside of a small group of individuals who are permitted transferees would result in the Private Placement Warrants having substantially the same terms as the Public Warrants, the Company determined that the fair value of each Private Placement Warrant is equivalent to that of each Public Warrant, with an insignificant adjustment for short-term marketability restrictions. As such, the Private Placement Warrants are classified as Level 2.

As of December31, 2020 and 2019, the aggregate values of the Private Placement Warrants and Public Warrants were approximately $97.2million and $23.4million, respectively, based on the closing price of THBR on that date of $13.22 and $9.95, respectively.

The following table presents the changes in the fair value of warrant liabilities:

____________

(1)      Changes in valuation inputs or other assumptions are recognized in change in fair value of warrant liabilities in the Statement of Operations.

(2)      Due to the use of quoted prices in an active market (Level 1) and the use of observable inputs for similar assets or liabilities (Level 2) to measure the fair values of the Public Warrants and Private Placement Warrants, respectively, subsequent to initial measurement, the Company had transfers out of Level 3 totaling approximately $23.4million during the period from August 9, 2019 through December 31, 2019.
