Issuable Upon Exercise of Warrants

Secondary Offering of

70,846,446 shares of Class A Common Stock and

This prospectus supplement no. 4 amends and supplements the prospectus dated July 13, 2021 (as supplemented or amended from time to time, the “Prospectus”), which forms a part of our Registration Statement on Form S-1 (No. 333-257629). This prospectus supplement is being filed to update and supplement the information in the Prospectus with the information contained in our Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on October 25, 2021 (the “Current Report”). Accordingly, we have attached the Current Report to this prospectus supplement.

The Prospectus relates to the issuance by us of up to 27,400,000 shares of our Class A common stock, par value $0.0001 per share (“Class A common stock”). Of these shares:

	●	17,250,000 shares are issuable upon the exercise of warrants (the “public warrants”) initially issued as part of the units issued in the initial public offering of Thunder Bridge Acquisition II, Ltd. (“Thunder Bridge II”);
	●	8,650,000 shares are issuable upon the exercise of warrants (the “private placement warrants”) initially issued to Thunder Bridge Acquisition II LLC (the “Sponsor”) in a private placement that occurred simultaneously with the initial public offering of Thunder Bridge II; and
	●	1,500,000 shares are issuable upon the exercise of warrants issued to an affiliate of the Sponsor in connection with loans it made to Thunder Bridge II prior to the closing of the Business Combination (as defined below) (the “sponsor warrants” and collectively with the public warrants and the private placement warrants, the “warrants”).

Each warrant entitles the holder thereof to purchase one share of our Class A common stock at a price of $11.50 per share. We will receive the proceeds from the exercise of the warrants, but not from the sale of the underlying shares of Class A common stock.

In addition, the Selling Securityholders identified in the Prospectus may, from time to time in one or more offerings, offer and sell up to 70,846,446 shares of our Class A common stock, of which:

	●	8,625,000 shares were exchanged in our Business Combination for shares of Class A common stock issued to the Sponsor in a private placement prior to Thunder Bridge II’s initial public offering (the “sponsor shares”);
	●	37,071,446 shares are issuable upon the exchange of an equal number of units (the “LLC Units”) representing limited liability company interests in Ay Dee Kay LLC, d/b/a indie Semiconductor (“ADK LLC”), our direct subsidiary;
	●	15,000,000 shares were issued in private placements in connection with our business combination with ADK LLC, which we completed on June 10, 2021 (the “Business Combination”);
	●	8,650,000 shares are issuable upon the exercise of private placement warrants; and
	●	1,500,000 shares are issuable upon the exercise of sponsor warrants.

The Selling Securityholders may also, from time to time in one or more offerings, offer and sell up to 8,650,000 private placement warrants and 1,500,000 sponsor warrants.

We will not receive any proceeds from the sale of our Class A common stock or the sale of the private placement warrants or sponsor warrants by Selling Securityholders, but we are required to pay certain offering fees and expenses in connection with the registration of the Selling Securityholders’ securities and to indemnify certain Selling Securityholders against certain liabilities.

The Selling Securityholders may offer and sell our Class A common stock, private placement warrants and sponsor warrants to or through one or more underwriters, dealers and agents, or directly to purchasers, on a continuous or delayed basis. In addition, certain Selling Securityholders may offer and sell these securities from time to time, together or separately. If the Selling Securityholders use underwriters, dealers or agents to sell such securities, we will name them and describe their compensation in a prospectus supplement. The price to the public of those securities and the net proceeds any Selling Securityholders expect to receive from that sale will also be set forth in a prospectus supplement.

Our Class A common stock and our public warrants are listed on the Nasdaq Capital Market (“Nasdaq”) under the symbols “INDI” and “INDIW,” respectively. On October 22, 2021, the closing price of our Class A common stock was $12.13 and the closing price for our public warrants was $3.71.

This prospectus supplement updates and supplements the information in the Prospectus and is not complete without, and may not be delivered or utilized except in combination with, the Prospectus, including any amendments or supplements thereto. This prospectus supplement should be read in conjunction with the Prospectus and if there is any inconsistency between the information in the Prospectus and this prospectus supplement, you should rely on the information in this prospectus supplement.

Investing in our securities involves risks that are described in the ”Risk Factors” section beginning on page 8 of the Prospectus.

Neither the SEC nor any state securities commission has approved or disapproved of the securities to be issued under the Prospectus or determined if the Prospectus or this prospectus supplement is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this prospectus supplement is October 25, 2021.

The principal and interest on this Note is payable in lawful money of the United States of America in immediately available funds at such place in the United States as Payee may from time to time designate in writing to Payor.

This Note is made pursuant to that certain Share Purchase Agreement (the “Purchase Agreement”), dated October __, 2021 by and among Payor and Payee.

Interest on the principal balance of this Note outstanding from time to time until paid in full in cash shall accrue at the rate equal to the Applicable Rate per annum, computed on the basis of a 365 or 366-day year, as appropriate, for the actual number of days elapsed, commencing on the date hereof (and on the date of issuance with respect to any PIK Note). “Applicable Rate” shall mean (A) 0% prior to the occurrence of any Event of Default (as defined below) hereunder and, (B) 15% after the occurrence and during the continuance of an Event of Default. Interest shall be payable in arrears upon Payee’s demand (such payment of interest, the “Interest”).

Upon any partial prepayment, at the request either of Payee or Payor, this Note shall be surrendered to Payor in exchange for a substitute note, which shall set forth the revised principal amount but otherwise be identical to this Note. In the event that this Note is prepaid in its entirety, this Note shall be surrendered to Payor for cancellation.

1.4. Payment Only on Business Days; Payments Free and Clear. Any payment hereunder which, but for this Section 1.4, would be payable on a day which is not a Business Day, shall instead be due and payable on the Business Day next following such date for payment.
