Purpose of Transaction (Item 4)
John C. Lame
The Shares covered by this Schedule 13D were acquired for investment purposes in the ordinary course of business. The Reporting Persons purchased shares based on their belief that the value of the Issuer is in excess of the current market price. The Reporting Persons' investment objective is to profit from appreciation in the market price of the Issuer's voting common stock. Mr. Lame intends to discuss the Issuer's returns for shareholders and the Issuer's strategy for the creation of shareholder value with management, the Issuer's board of directors, and other shareholders of the Issuer. Although the Reporting Persons have no other specific plan or proposal that relates to or would result in any of the actions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D, consistent with their investment purpose, the Reporting Persons at any time and from time to time may acquire additional shares of voting common stock or dispose of any or all of the shares of voting common stock depending upon an ongoing evaluation of the investment in the common stock, prevailing market conditions, other investment opportunities, liquidity requirements of the Reporting Person, and/or other investment considerations.Item 4 of the SCHEDULE 13D filed 2026-04-08

Questions about who owns First Internet Bancorp
Who owns First Internet Bancorp?
On this page, one holder's latest ownership filing reports 5% or more of First Internet Bancorp: Dimensional Fund Advisors LP (5%, Schedule 13G/A, filed 2026-01-21).
When did Dimensional Fund Advisors LP buy into First Internet Bancorp?
The filings give report dates, not purchase dates. The earliest filing from Dimensional Fund Advisors LP on this page is the Schedule 13G/A, filed 2026-01-21, reporting 5%. That earliest filing is itself an amendment, which updates an earlier report.
Is this an audit or a full list?
Neither. The ownership list on this page covers only Schedule 13D and 13G filings, which holders make once they own 5% or more of a class of shares (an amendment can report a stake that has since fallen below 5%); 5 such filings are shown here. It is not an audit and not a full cap table: holders who never reached 5% are not listed, and a stake can change after its latest filing.

Where this comes from
Anyone who comes to own more than 5% of a class of a listed company's voting shares has to tell the SEC. A holder who may seek to change or influence the company files Schedule 13D, and has to say in Item 4, "Purpose of Transaction", what it intends to do. A holder with no such intent, such as many index and passive funds, may file the shorter Schedule 13G. Both are amended when the stake changes, including when it falls below 5%.
Every row here is one of those filings, linked to the filing itself. Percentages and share counts are exactly as the holder filed them, for the holder the filing names; an amendment showing a lower figure is shown as filed. Item 4 text is quoted word for word. Where a 13D's Item 4 contains a sentence stating a definite intent to influence the company, that sentence is marked and quoted; the page does not describe the holder or its motives beyond the words it filed. Nothing here is investment advice.
