Branchless banking changes the cost structure
First Internet Bank delivers banking through a branchless model, while its parent describes both commercial and consumer lending. Digital distribution can reach customers beyond a local branch market. It also shifts costs toward customer acquisition, technology, remote service and the expertise needed to originate and manage particular loan types. The company’s July 2026 release supplies the dated financial context; the economics discussed here are analytical, not a claim that every digital channel is cheaper. [2]
For a depositor, the product includes transferring money, obtaining help, renewing a certificate and resolving an account restriction. For a business borrower, it also includes access to people who understand the transaction. A bank can have no conventional branch network while still needing substantial relationship and operations staff. Counting branches is therefore a poor substitute for measuring cost per active relationship.
National reach can diversify geography while leaving funding sensitive to a common acquisition channel or rate comparison. Customers attracted by a savings rate may use the account differently from customers who depend on payments or lending. That is a reason to study account behavior, not to assume that digitally acquired deposits are inherently unstable.
The bank and the reporting entity
First Internet Bank of Indiana is the insured subsidiary of First Internet Bancorp. The company’s June 30, 2026 disclosures reported consolidated assets of approximately $5.6 billion, deposits of $4.8 billion and stockholders’ equity of $363.5 million. These measures describe the holding-company consolidated balance sheet at that date; they are not current intraday values. [1][3]
The bank delivers accounts nationally through digital channels and operates commercial and consumer lending portfolios. Remote distribution lowers dependence on branches but increases the importance of online acquisition, identity verification, fraud controls, third-party infrastructure and reliable service operations. The filing and earnings release describe the company’s own reported mix and performance. [1][2]
Earnings, portfolio mix and comparable margins
The Q2 release reported a 2.39% net interest margin and a 2.47% fully taxable-equivalent (FTE) net interest margin, alongside a $13.4 million provision for credit losses; the company also reported 30-day of 0.78% for performing loans. Each metric is definition- and period-specific. Provision reflects expectations and portfolio growth as well as realized deterioration; delinquency is a lagging measure and may exclude nonperforming assets. [2]
A useful review pairs these measures with criticized and classified loans, , nonaccruals, reserve coverage, loan growth and funding costs. Digital and specialty portfolios can be sensitive to commercial real estate, construction, equipment and consumer credit cycles; the filing’s segment notes are more informative than a single blended ratio. [1]
An FTE adjustment restates qualifying tax-advantaged income on a comparable taxable basis. It does not represent additional cash interest received. Use the same margin basis when comparing institutions or periods; the 2.47% measure should not be labeled as the unadjusted margin. [2]
Acquisition payback and service capacity
Hypothetical: acquiring a funded deposit account costs $180. Its average balance is $30,000 and produces a 1% annual funding advantage over a comparable alternative, or $300. If annual direct servicing costs are $60, the simplified recurring contribution is $240 and acquisition payback is nine months. A funding advantage of only 0.5% would reduce contribution to $90 and extend payback to two years. Neither case is a forecast or a quoted First Internet rate.
This calculation excludes common technology expense, costs, taxes and account attrition. A high opening balance can make payback look favorable even if the customer moves most cash shortly afterward. Measure average retained balances and the share of accounts still active after promotional terms end. Avoid treating a favorable first-month acquisition result as lifetime profitability.
On the lending side, separate recurring spread and servicing economics from transaction-dependent gains or fees. A specialized loan can require more experienced staff and exception handling than a standard product. Greater revenue per loan may justify that work; volume alone does not establish operating leverage. The relevant comparison is contribution after direct origination, funding and expected loss costs, followed by a transparent treatment of shared overhead.
Evidence of durable progress would combine retained customers, consistent service, disciplined pricing and improving economics on comparable portfolios. A digital interface is one distribution method. Its business value depends on whether customers complete important financial tasks reliably and whether the bank can provide that service at sustainable cost.
What would change the view
Digital scale can support national distribution without a branch footprint, but creates concentration in technology, marketing and remote fraud prevention. Deposit competition can pressure margin, while rapid asset growth can consume capital and increase underwriting workload. Track quarterly loan composition, deposit mix, sources, technology incidents and operating expenses. [1][2]
Bank-level call reports and holding-company filings answer different questions; reconcile rather than merge them casually. The June 30, 2026 figures should be refreshed from the next filing before being used as present-day facts. Nothing in public metrics establishes a confidential supervisory rating.
