- Company to hold earnings call today at 5pm ET -

First Internet Bancorp (the "Company") (NASDAQ:INBK), the parent company of First Internet Bank (the "Bank"), announced today financial and operational results for the first quarter ended March 31, 2026.

Key Business Updates

Revenue Momentum: Growth in net interest income (up 26%) and fully-taxable equivalent ("FTE") net interest margin (now 2.45%) drove quarterly revenue up 21% year-over-year to $43.1 million. When combined with well-managed expenses, pre-provision net revenue grew 51% year-over-year.
Credit Trends: Provision for credit losses for the first quarter of 2026 of $16.3 million. The provision reflects our quarterly CECL re-measurement of expected lifetime losses for the portfolio, based on observed credit performance and updates to current conditions. During the first quarter, ongoing proactive credit actions continued to drive progress in resolving problem credits. Notably, nonaccrual unguaranteed SBA and franchise finance balances declined from the fourth quarter of 2025.
Strong Loan Production: Commercial loan production remained strong during the first quarter led by construction and single tenant lease financing. Additionally, loan pipelines at the end of the quarter were solid, setting the stage for continued loan growth as we move through 2026.

"We kicked off the new year with strong first quarter results, demonstrating the resilience of our diversified business model and the solid foundation we've built to navigate an uncertain macroeconomic environment from a position of strength," said David Becker, Chairman and CEO of First Internet Bancorp. "We generated 21% revenue growth, 51% growth in pre-provision net revenue, and expanded our net interest margin 54 basis points year-over-year to 2.45%, reflecting years of disciplined balance sheet repositioning and proactive liability management. We're also seeing tangible evidence that our enhanced underwriting standards and risk management initiatives are yielding favorable results, particularly in our SBA portfolio where unguaranteed nonperforming loans and delinquencies have improved both sequentially and year-over-year."

"Beyond the strong quarterly financial results, we continued to make strategic investments in AI and digital capabilities that are already delivering measurable results - our virtual customer service agents resolve 45% of inquiries, our fraud detection agents enhance security, and our Net Promoter Scores are well above industry averages. Additionally, our Banking-as-a-Service partnerships continue to grow and provide valuable deposit funding flexibility, while our commercial lending pipelines remain robust across multiple verticals. With improving credit trends, strong margin momentum, and disciplined cost management, we are well-positioned to deliver improving profitability through 2026 and accelerating performance into 2027."

Full Year 2026 Outlook

The Company is broadly maintaining its 2026 guidance. However, management acknowledges the heightened macroeconomic uncertainty, including volatile energy prices and other geopolitical developments, which could have negative impacts. Regarding loan growth specifically, while commercial pipelines remain robust, the Company recognizes that the full-year target of 15-17% may prove ambitious due to higher-than-expected loan payoffs and potential further tightening of underwriting standards due to macro uncertainties.

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, adjusted total revenue, pre-provision net revenue, adjusted pre-provision net revenue, adjusted noninterest income, adjusted income before income taxes, adjusted income tax (benefit) provision, adjusted net income, adjusted diluted earnings per share, adjusted return on average assets, adjusted return on average shareholders' equity, adjusted return on average tangible common equity, 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."
