NOTICE OF ANNUAL MEETING OF STOCKHOLDERS

TO BE HELD ON MAY 28, 2026

Notice is hereby given that the Annual Meeting of Stockholders of indie Semiconductor, Inc., a Delaware corporation, will be held virtually on May 28, 2026, at 9:00 a.m., Pacific Time. The meeting can be accessed via the link provided following registration where you will be able to listen to the meeting live, submit questions and vote online. If you plan to attend the virtual Annual Meeting, please see the instructions on page 3 of the attached Proxy Statement. You will be required to register in advance athttps://web.viewproxy.com/indi/2026 prior to the deadline of May 26, 2026 at 5:00 p.m., Pacific Time in order to attend the meeting. There will be no physical location for stockholders to attend. Stockholders only may participate by logging in with the link provided upon registration. We believe that a virtual Annual Meeting provides greater access to those who want to attend and therefore have chosen this format over an in-person meeting.

At the Annual Meeting, stockholders will be asked to consider and vote upon the following proposals:

To elect three Class II directors to our Board of Directors for terms expiring at the 2029 Annual Meeting of Stockholders and until their respective successors are elected and qualified;

To approve, on an advisory basis, the compensation of our named executive officers, as disclosed in this Proxy Statement;

To approve an amendment to the 2021 Omnibus Equity Incentive Plan (the “2021 Plan”) to increase the number of shares of Class A Common Stock reserved for issuance thereunder by 17,000,000 shares;

To ratify the appointment of KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026; and

To transact such other business as may properly come before the meeting or any adjournment or postponement thereof.

Our Board of Directors recommends that you vote “FOR” each of the nominees for Class II directors (Proposal One); “FOR” the approval, on an advisory basis, of the compensation of our named executive officers as disclosed in this Proxy Statement (Proposal Two); “FOR” the amendment to the 2021 Plan (Proposal Three); and “FOR” ratification of the appointment of the independent registered public accounting firm for fiscal 2026 (Proposal Four).

This year we are using the internet as our primary means of furnishing our proxy materials to stockholders. Accordingly, most stockholders will not receive printed copies of our proxy materials. We are instead mailing a Notice of Internet Availability of Proxy Materials with instructions for accessing the proxy materials and voting via the internet (the “Notice”). This delivery method allows us to conserve natural resources and reduce the cost of delivery while also meeting our obligations to you, our stockholders, to provide information relevant to your continued investment in indie. If you received the Notice by mail and would like to receive a printed copy of our proxy materials, you should follow the instructions in the Notice for requesting those materials. We encourage you to review the proxy materials and vote your shares.

Our Board of Directors has fixed the close of business on March 30, 2026 as the record date for determining the stockholders entitled to notice of, and to vote at, the Annual Meeting or any adjournments. For 10 days prior to the Annual Meeting, a list of such stockholders will be available for inspection by any stockholder at our principal executive offices during normal business hours.

If you were a beneficial holder as of March 30, 2026 (i.e. you held your shares in “street name” through an intermediary, such as a bank or broker), you must obtain a legal proxy, executed in your favor, from the holder of record in order to vote at the Annual Meeting, which you may upload during the registration process.

We encourage you to access the Annual Meeting before the start time of 9:00 a.m., Pacific Time, on May 28, 2026. Please allow ample time for online check-in, which will begin at 8:45 a.m., Pacific Time, on May 28, 2026.

Whether or not you plan to attend the virtual Annual Meeting, our Board of Directors urges you to read the attached Proxy Statement and submit a proxy or voting instructions for your shares via the internet or by telephone, or completing, dating, signing and returning your proxy card or voting instruction form in the pre-addressed, postage-paid envelope provided. We encourage you to submit your proxy or voting instructions via the internet, which is convenient, helps reduce the environmental impact of our Annual Meeting and saves us significant postage and processing costs. For instructions on how to submit your proxy or voting instructions, please refer to “General Information - Voting Methods” beginning on page 4 of the attached Proxy Statement.

By Order of the Board of Directors,

Audrey Wong

Secretary
