First Internet Bancorp (the "Company") (NASDAQ:INBK), the parent company of First Internet Bank (the "Bank"), announced today financial and operational results for the third quarter ended September 30, 2025.

"Our third quarter results demonstrated strong operational momentum with solid growth in net interest income and continued improvement in our net interest margin," said David Becker, CEO and Chairman of First Internet Bancorp. "We have now achieved eight consecutive quarters of increasing net interest income, attributable to higher yields on our earning assets and reduced funding costs, both of which have materially enhanced our operating efficiency. Additionally, we attained significant growth in fintech deposits, which has enabled us to maintain strong balance sheet liquidity, as evidenced by our favorable loans-to-deposits ratio. We also completed a major loan sale and moved deposits off balance sheet which will enhance our regulatory capital ratios and provide balance sheet flexibility."

"In the third quarter, we took decisive action to address credit issues in our small business lending and franchise finance portfolios, which provides us with a cleaner credit profile and sets the stage for improved performance in future quarters. Entering the fourth quarter, we see encouraging signs in both portfolios with asset quality improving and delinquencies at their lowest level in a year. Our loan pipelines remain robust, and we are now well-positioned to grow earnings and accelerate our ability to achieve a ROAA of 1%. I wish to express my sincere appreciation for the dedication and diligence of our team as we worked extremely hard this quarter to position the Company for success going forward and enhance shareholder value."
