Ladies and Gentlemen:

I have acted as counsel to indie Semiconductor, Inc., a Delaware corporation (the “Company”), in connection with the preparation of the Registration Statement on Form S-3 (the “Registration Statement”) filed by the Company with the Securities and Exchange Commission (the “Commission”) on the date hereof under the Securities Act of 1933, as amended (the “Securities Act”). The Registration Statement relates to the offer and sale from time to time, pursuant to Rule 415 of the General Rules and Regulations of the Commission promulgated under the Securities Act, of an indeterminate amount of the following securities: (i) shares of the Company’s Class A common stock, par value $0.0001 per share (“Common Stock”); (ii) shares of the Company’s preferred stock, par value $0.0001 per share (“Preferred Stock”), in one or more series; (iii) debt securities of the Company, which may be either senior debt securities or subordinated debt securities (“Debt Securities”), to be issued pursuant to an indenture to be entered into between the Company and a trustee to be named in such indenture (the “Trustee”) in the form filed as an exhibit to the Registration Statement (the “Base Indenture”); (iv) warrants to purchase shares of Common Stock (the “Common Stock Warrants”), which may be issued pursuant to a warrant agreement between the Company and a warrant agent to be appointed prior to the issuance of Common Stock Warrants (the “Common Stock Warrant Agreement”); (v) warrants to purchase shares of Preferred Stock (the “Preferred Stock Warrants”), which may be issued pursuant to a warrant agreement between the Company and a warrant agent to be appointed prior to the issuance of Preferred Stock Warrants (the “Preferred Stock Warrant Agreement”); (vi) warrants to purchase Debt Securities (the “Debt Security Warrants” and, together with the Common Stock Warrants and the Preferred Stock Warrants, the “Warrants”), which may be issued pursuant to a warrant agreement between the Company and a warrant agent to be appointed prior to the issuance of Debt Security Warrants (together with the Common Stock Warrant Agreement and the Preferred Stock Warrant Agreement, the “Warrant Agreement”); (vii) rights to purchase shares of Common Stock (the “Common Stock Rights”) to be issued pursuant to a rights agreement between the Company and a rights agent to be appointed prior to the issuance of Common Stock Rights (the “Common Stock Rights Agreement”); (viii) rights to purchase shares of Preferred Stock, (the “Preferred Stock Rights” and, together with the Common Stock, the “Rights”) to be issued pursuant to a rights agreement between the Company and a rights agent to be appointed prior to the issuance of Preferred Stock Rights (together with the Common Stock Rights Agreement, the “Rights Agreement”); and (ix) units consisting of two or more classes or series of Common Stock, Preferred Stock, Debt Securities, Warrants and/or Rights (the “Units” and together with the Common Stock, Preferred Stock, Warrants and Rights, the “Securities”) to be issued pursuant to a unit agreement between the Company and a unit agent to be appointed prior to the issuance of the Units (the “Unit Agreement” and, together with the Indenture, the Warrant Agreement and the Rights Agreement, the “Agreements”);

In rendering the opinion below, I have examined originals or copies of those corporate and other records and documents as we considered appropriate including, without limitation:

In my examination, I have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to me as originals, the conformity to original documents of all documents submitted to us as certified, conformed or photostatic copies and the authenticity of the originals of such latter documents. I have also assumed that New York law will be chosen to govern each of the Agreements and that such choice of law is a valid and legal provisions. To the extent that the Company’s obligations depend on the enforceability of any agreement against the other parties to the agreement, I have assumed that such agreement is enforceable against such other parties. As to any facts material to the opinions expressed herein which were not independently established or verified, I have relied upon oral or written statements and representations of officers and other representatives of the Company. In addition, I have obtained and relied upon those certificates of public officials I considered appropriate.

In connection with each of the opinions expressed below, I have assumed that, at or prior to the time of delivery of any Security, (i) the effectiveness of the Registration Statement has not been terminated or rescinded, (ii) a prospectus supplement, to the extent required by the Securities Act and the relevant rules and regulations of the Commission thereunder, has been prepared, delivered and has been or will be timely filed with the Commission describing each class or series of Securities offered thereby and any other matters required thereby and will comply with the Securities Act and the applicable rules and regulations thereunder, (iii) the Company is validly existing and in good standing under the laws of Delaware, with all corporate power and authority to enter into the Agreements to which it is or may be a party and to perform its obligations thereunder, (iv) the definitive terms of the issuance and sale of each class or series of Securities will have been duly established in accordance with the authorizing resolutions adopted by the Company’s Board of Directors (or an authorized committee thereof) and in conformity with the Organizational Documents and applicable law, (v) all Securities will be issued and sold in the manner contemplated by the Registration Statement and any applicable prospectus supplement and any Securities that consist of shares of Common Stock or Preferred Stock, including Common Stock or Preferred Stock which may be issued upon conversion, exercise or exchange of any other Securities convertible into or exercisable or exchangeable for Common Stock or Preferred Stock (a “Convertible Security”), will have been authorized and the requisite number of shares of Common Stock or Preferred Stock will have been reserved for issuance upon the conversion, exercise or exchange of any Convertible Security, in each case, within the limits of the then remaining authorized but unissued and unreserved amounts of such Common Stock or Preferred Stock, and (vi) there has not occurred any change in law affecting the validity or enforceability of such Security. I have also assumed that none of the terms of any Security to be established after the date hereof, nor the issuance and delivery of such Security, nor the compliance by the Company with the terms of such Security, will violate any applicable law or public policy or result in a violation of any provision of any instrument or agreement then binding upon the Company or any restriction imposed by any court or governmental body having jurisdiction over the Company.
