Fishers, Indiana, July 30, 2026 – First Internet Bancorp (the “Company”) (Nasdaq: INBK), the parent company of First Internet Bank (the “Bank”), announced today financial and operational results for the second quarter ended June 30, 2026.

Key Business Updates

•Significant Improvement in Credit Quality: Provision for credit losses for the second quarter of 2026 of $13.4 million, down from $16.3 million in the first quarter of 2026. Notably, total nonaccrual loans declined for the second consecutive quarter, and are down 14% from the first quarter of 2026. Furthermore, delinquencies 30 days or more past due decreased to 0.78% of total performing loans, down from 1.06% in the first quarter of 2026, driven by a significant decline in small business lending delinquencies.

•Revenue Momentum: Growth in net interest income (up 16%), fully-taxable equivalent (“FTE”) net interest margin of 2.47%1 (up 43 basis points), and strong noninterest income drove quarterly revenue up 23% year-over-year to $41.1 million. When combined with well-managed expenses, pre-provision net revenue grew 28% year-over-year to $15.0 million1.

•Solid Loan Production: Commercial loan balances continued to grow during the second quarter led by construction / investor commercial real estate and single tenant lease financing. While period end and average loan balances were impacted by early payoffs, loan pipelines at the end of the quarter were solid, setting the stage for continued loan growth in the second half of 2026. Additionally, the Company expects to increase its retention of embedded finance small business loans originated for one of its fintech partners, an asset class with very attractive risk-return characteristics.

•Fee Revenue Acceleration: Noninterest income grew 56% year-over-year, supported by the continued growth in the Banking-as-a-Service (“BaaS”) platform. As we have selectively increased the number of fintech partners, and have expanded relationships with existing partners, fee revenue from BaaS increased 172% from the prior year period.

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."

Full Year 2026 Outlook

•Diluted earnings per share of $2.35 to $2.45

•Loan growth in the range of 4% to 6%, driven by solid pipelines across our commercial lending verticals

•Outlook reflects early payoffs in commercial lending areas and lower retention of small business lending balances as secondary market premiums remain attractive

•FTE net interest margin expansion, reaching 2.75% to 2.80% by the fourth quarter of 2026, driven by ongoing deposit repricing and optimized asset mix

•FTE net interest income in the range of $141 million to $142 million

•Noninterest income in the range of $40.5 million to $41 million, reflecting continued BaaS growth and increasing small business lending originations and gain on sale activity in the second half of 2026

•Noninterest expense in the range of $106 million to $107 million

•Provision for credit losses, including net charge-offs and reserves related to problem loans, of $47 million to $48 million

•Continual improvement is expected throughout the second half of 2026

Non-GAAP Financial Measures

This press release contains financial information determined by methods other than in accordance with U.S. generally accepted accounting principles (“GAAP”). Non-GAAP financial measures, specifically tangible common equity, tangible assets, tangible book value per common share, tangible common equity to tangible assets, average tangible common equity, return on average tangible common equity, total interest income – FTE, net interest income – FTE, net interest margin – FTE, pre-provision net revenue adjusted tangible common equity, adjusted tangible assets, adjusted tangible common equity to adjusted tangible assets, adjusted nonperforming loans to total loans and adjusted allowance for credit losses – loans to nonperforming loans are used by the Company’s management to measure the strength of its capital and analyze profitability, including its ability to generate earnings on tangible capital invested by its shareholders. Although management believes these non-GAAP measures are useful to investors by providing a greater understanding of its business, they should not be considered a substitute for financial measures determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. Reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures are included in the table at the end of this release under the caption “Reconciliation of Non-GAAP Financial Measures.”
