EXPLANATORY NOTE

First Internet Bancorp (the “Company”) is filing this Post-Effective Amendment No. 2 to Form S-8 Registration Statement (this “Post-Effective Amendment”) to deregister certain securities originally registered by the Company pursuant to its Registration Statement on Form S-8 (File No. 333-188741) filed with the Securities and Exchange Commission (the “Commission”) on May 21, 2013, as amended by the Post-Effective Amendment No. 1 thereto filed with the Commission on May 18, 2022 (collectively referred to herein as the “Prior Registration Statement”) with respect to shares of the Company’s common stock, no par value per share (the “Common Stock”), thereby registered for offer or sale pursuant to the First Internet Bancorp 2013 Equity Incentive Plan (the “2013 Plan”). The Prior Registration Statement registered 750,000 shares of Common Stock with respect to the 2013 Plan.

The Company has since adopted a new equity incentive plan, the First Internet Bancorp 2022 Equity Incentive Plan (the “2022 Plan”), which replaced the 2013 Plan as of May 16, 2022, the date the Company’s shareholders approved the 2022 Plan. No future awards will be made under the 2013 Plan. This Post-Effective Amendment is being filed solely to deregister shares registered under the Prior Registration Statement that will not be used for awards under the 2013 Plan. Such shares are hereby deregistered under the Prior Registration Statement.

As of the date of this Post-Effective Amendment, the total number of shares of Common Stock subject to awards that expired, were cancelled, were forfeited, or were settled in cash under the 2013 Plan, and not yet registered under the 2022 Plan, is 253,381 (the “Newly Available 2022 Plan Shares”). These Newly Available 2022 Plan Shares are no longer available for new awards under the 2013 Plan and will not be issued under the 2013 Plan.

The Registrant is concurrently filing a separate Registration Statement on Form S-8 to register the Newly Available 2022 Plan Shares for issuance under the 2022 Plan. This Post-Effective Amendment is hereby filed to reflect that, following the date hereof, the Newly Available 2022 Plan Shares may not be issued under the 2013 Plan and to deregister the Newly Available 2022 Plan Shares under the Prior Registration Statement. As of the date of this Post-Effective Amendment, there are no remaining outstanding awards under the 2013 Plan, and all of the shares of Common Stock that were initially registered under the Prior Registration Statement have either been issued pursuant to awards under the 2013 Plan or deregistered pursuant to this Post-Effective Amendment.

SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, the Company certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Post-Effective Amendment No. 2 to Form S-8 Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the city of Fishers, State of Indiana, on May 20, 2025.
