First Internet (INBK) Q1 2026 Earnings Transcript

First Internet Bancorp reported Q1 revenue of $43.1 million, up 21% year over year, with net interest margin expanding to 2.45% FTE, up 54 bps from a year ago. Net income was $2.5 million, or $0.29 per diluted share, while fintech-driven payment volume topped $82 billion and average fintech deposits rose 186% to $2.4 billion. Management kept full-year guidance broadly intact but flagged elevated Q2 credit costs, cautious loan growth assumptions, and continued margin improvement from lower-cost funding and redeployed cash.

Analysis

INBK’s setup is less about near-term earnings acceleration than about a potential re-rating of the business mix. The market is likely still valuing it as a credit-cleanup story, but the second-order effect is that every incremental dollar of low-cost fintech deposits plus every retained SBA loan converts a larger share of revenue into recurring spread income, which is a much better multiple than episodic gain-on-sale economics. If management executes on the stated deposit redeployment and balance-sheet re-levering, the earnings stream should become less volatile just as the market is likely underestimating the durability of fee-related funding.

The key debate is whether credit normalization is truly a 2H26 event or whether the normalization path remains lumpy enough to cap sentiment. The important tell is not headline charge-offs; it is whether problem-asset resolution continues to beat reserve build and whether franchise/SBA credit migration keeps improving into the third quarter. If that happens, the stock has room to work because investors will start capitalizing forward NII and fee income rather than penalizing current-period provisions.

The contrarian angle is that consensus may be too focused on the risk side of the ledger while missing the funding advantage embedded in the fintech platform. A bank with a structurally cheaper, more flexible deposit base can preserve margin even if the Fed stays on hold, and that creates operating leverage without requiring heroic loan growth assumptions. The main downside is that the same underwriting tightening that protects credit can also slow balance-sheet expansion, so the bull case is really a margin/quality story, not a volume story.

For trading, the clean expression is a medium-duration long if you believe provisions peak in Q2 and NIM continues to expand 10-15 bps per quarter. The setup works best if loan growth disappoints modestly but funding costs keep falling, because that shifts the debate from growth scarcity to earnings quality. The stock likely needs one more quarter of visible credit improvement before multiple expansion becomes self-sustaining.

Key Decisions for Investors

• Long INBK into the next 1-2 quarters on the thesis that margin expansion outruns credit costs; target a 15-25% upside re-rating if NIM keeps improving and provisions step down as guided.
• Use a staggered entry in INBK rather than a full position now; add on any post-earnings weakness if the market overreacts to Q2 provision noise, since that is the likely peak-credit quarter.
• Pair trade: long INBK / short a higher-quality regional bank with less margin expansion torque over the next 2 quarters, to isolate the value of cheap fintech funding and balance-sheet remix.
• If options liquidity allows, buy INBK 3-6 month calls financed by selling a higher strike call; the upside is a multiple expansion on visible NII growth, while downside is bounded if credit headlines reassert.
• Do not chase on a breakout until there is evidence of sustained loan growth re-acceleration; otherwise the risk/reward skews toward a value trap if underwriting tightens faster than deposits redeploy.
