Key Business Updates

Second Quarter 2026 Financial Performance

“Our second quarter results reflect strong momentum across the business, paired with a meaningful and encouraging improvement in our credit trends," said David Becker, Chairman and CEO of First Internet Bancorp. "Total revenue grew 23% year-over-year and pre-provision net revenue increased nearly 28%, while our fully-taxable equivalent net interest margin expanded 43 basis points to 2.47%. Just as importantly, our credit provision declined, nonperforming loans decreased sequentially for the first time in several quarters, small business lending net charge-offs improved significantly, and delinquencies across the portfolio fell sharply - clear evidence that the proactive credit actions we have taken over the past several quarters are working.

"We are equally encouraged by the acceleration of our fee-based businesses. Noninterest income grew more than 56% year-over-year, driven by the continued strength of our Banking-as-a-Service platform and the deepening of our fintech partnerships, including an expanded relationship with jaris under which we will retain all small business loans originated through its platform. We also continue to invest in AI, automation, and digital capabilities that drive efficiency and elevate the customer experience. With improving credit, growing fee income, and a more capital-efficient balance sheet, we are well-positioned to build on this momentum through the remainder of 2026 and beyond."
