Breaking Down First Internet Bancorp (INBK) Financial Health: Key Insights for Investors

If you only glanced at First Internet Bancorp's (INBK) third quarter 2025 report, you defintely saw a shocking headline: a net loss of $41.6 million and diluted earnings per share (EPS) of -$1.43, a massive miss that sent the stock near its 52-week low of $19.54. But as a seasoned analyst, I know the real story is in the details, and this quarter was a strategic clean-up, not a collapse. Here's the quick math: the loss was largely a one-time hit from the planned sale of $836.9 million in single tenant lease financing loans, which was a necessary move to boost their regulatory capital ratios, now showing a Common Equity Tier 1 (CET1) ratio of 9.24%. Plus, the core business is actually performing well, with net interest income climbing to $30.4 million and the net interest margin (NIM) expanding to 2.04%, marking eight consecutive quarters of net interest income growth. So, is this a broken bank or a bank that just took its medicine? We need to look past that big red number and map the near-term risks and opportunities to see if First Internet Bancorp is truly positioned to accelerate its path toward a 1% return on average assets (ROAA) goal.

Revenue Analysis

You need to know where First Internet Bancorp (INBK) is actually making its money, especially after a volatile 2025. The direct takeaway is that while adjusted total revenue is growing-up a solid 30% year-over-year in Q3 2025-the growth is heavily reliant on the core banking function of net interest income, which is a positive sign for operational efficiency.

The bank's revenue is fundamentally split between Net Interest Income (NII) and Non-Interest Income (fee-based services). For the third quarter of 2025, the adjusted total revenue hit $43.5 million. A significant portion of that comes from NII, which is the profit from lending money at a higher rate than the cost of deposits. This NII figure was $30.4 million in Q3 2025, an 8% increase from the prior quarter. That's a good trend: NII is up for eight consecutive quarters, driven by higher asset yields and lower funding costs.

Here's the quick math on the Q3 2025 revenue breakdown:

What this estimate hides is the one-time event that impacted the GAAP (Generally Accepted Accounting Principles) revenue. In Q3 2025, the company took a pre-tax loss of $37.8 million on the sale of single tenant lease financing loans, which was a strategic move to clean up the balance sheet and boost regulatory capital. This is a crucial distinction between adjusted operating performance and reported GAAP figures.

The primary revenue sources for First Internet Bancorp (INBK) are tied directly to its digital-first lending model, which includes a diverse mix of commercial and consumer products. The key segments contributing to the revenue pool are:

• Commercial Lending: Includes commercial real estate, construction loans, and commercial & industrial (C&I) loans, which form the base of NII.
• Specialty Finance: This covers niche areas like SBA financing (Small Business Administration), which is a major source of Non-Interest Income. For example, SBA gain-on-sale revenue was $8.6 million in Q1 2025 alone.
• Consumer/Small Business: Services like consumer loans, small business lending, and franchise finance also feed the NII and fee income streams.

The overall full-year 2025 revenue is projected to be around $120.42 million, though this estimate has been revised down slightly in recent months. The continued expansion of the Net Interest Margin (NIM)-which hit 2.04% in Q3 2025-is the defintely the most important trend to watch, showing better pricing power on earning assets. You can dive deeper into the strategic alignment of these segments by reviewing their Mission Statement, Vision, & Core Values of First Internet Bancorp (INBK).

Profitability Metrics

You need to know if First Internet Bancorp (INBK) is making money and how efficiently they're doing it. The short answer for the third quarter of 2025 is that core operations are profitable, but a major strategic move drove a significant net loss. To be clear, the bank is trading short-term pain for long-term balance sheet health.

In the third quarter (Q3) of 2025, First Internet Bancorp reported an adjusted total revenue of $43.5 million, a strong sequential increase of 30%. However, the GAAP net loss was $41.6 million, primarily due to a pre-tax loss of $37.8 million from the strategic sale of $836.9 million in single-tenant lease financing loans. This sale was a purposeful clean-up, but it definitely hit the bottom line hard. Excluding that one-time loss, the adjusted net loss was still $12.5 million.

Gross and Operating Profitability: The Core Engine

For a bank, the most important profitability metric is the Net Interest Margin (NIM), which tells you the spread between what they earn on loans and what they pay on deposits. This is your 'gross profit' engine. The trend here is positive, which is key:

• Net Interest Margin (NIM): INBK's NIM was 2.04% (GAAP) in Q3 2025, continuing an eight-quarter streak of net interest income growth. This shows they are successfully managing their funding costs and increasing loan yields.
• Operating Profit Margin: We use Pre-Tax, Pre-Provision Income (PTPP) as the best proxy for operating profit, as it removes taxes and the highly variable loan loss provisions. The adjusted PTPP was $18.1 million in Q3 2025. Here's the quick math: with adjusted total revenue of $43.5 million, this gives an operating profit margin (PTPP Margin) of approximately 41.61%. That's a solid operating leverage.

This operational efficiency is a bright spot. You see the management team keeping a tight rein on non-interest expense (operating costs), which we calculate at about $25.4 million for the quarter ($43.5M Revenue - $18.1M PTPP).

Net Profitability and Industry Comparison

The net result, however, is significantly impacted by credit risk management. The bank recognized a substantial $34.8 million provision for credit losses in Q3 2025, mostly tied to small business lending and franchise finance portfolios. This provision, plus the loan sale loss, drove the adjusted net loss margin to approximately -28.74% for the quarter.

When you compare this to the industry, you see the challenge and the opportunity:

The core takeaway is that First Internet Bancorp is currently a turnaround story. Management is making tough, expensive decisions-like the $37.8 million loan sale loss-to clean up the balance sheet and improve future profitability. They are guiding for a fully-taxable equivalent NIM of 2.4% to 2.5% for Q4 2025, which shows confidence in their current strategy. The long-term success hinges on their ability to execute on this and achieve their goal of a 1% Return on Average Assets (ROAA).

Debt vs. Equity Structure

When you look at First Internet Bancorp (INBK)'s balance sheet, the debt-to-equity (D/E) ratio tells a clear story: the company leans more on debt-or, more accurately for a bank, non-equity funding sources like deposits and borrowings-than its peers, but this is a deliberate strategy the bank is actively managing.

As of the most recent quarter in 2025, First Internet Bancorp's total debt was approximately $355.14 million. This figure represents the company's non-deposit borrowings, which are a mix of short-term and long-term obligations used to fund its loan portfolio and operations. For a bank, the total liability structure is more complex than a typical manufacturer, but the core capital metric is still key. The total shareholders' equity stood at approximately $390.2 million as of the second quarter of 2025.

Here's the quick math on leverage: The Debt-to-Equity ratio for First Internet Bancorp was approximately 1.01 (or 101%) as of October 2025. To be fair, a D/E ratio of 1.01 means the company has about one dollar of debt for every dollar of equity. However, this is significantly higher than some regional bank peers, where a Debt/Common Equity average can hover closer to 35%. This higher ratio signals a more aggressive use of financial leverage (borrowed funds) to drive asset growth, which can amplify returns but also increases risk if asset quality declines.

The company is defintely focused on optimizing this balance, and you saw a major strategic move in the third quarter of 2025 to address it. This move was a form of major refinancing activity, even without a formal credit rating change.

• Strategic Asset Sale: The bank sold $836.9 million of single tenant lease financing loans to Blackstone.
• Capital Enhancement: This action immediately strengthened their regulatory capital ratios.
• Improved Ratios: The Common Equity Tier 1 (CET1) ratio, a critical measure of a bank's ability to absorb losses, improved to 9.24% in Q3 2025.

This loan sale was a clear signal that the company is prioritizing capital strength and balance sheet flexibility over simply maximizing asset size. They took a pre-tax loss of $37.8 million on the sale, but the trade-off was a cleaner, more resilient balance sheet and an improved interest rate risk profile. This is a proactive step to manage the risk inherent in a higher-leverage model, shifting the balance of their financing mix toward greater equity and regulatory capital strength.

Their financing philosophy balances using debt to fund growth in high-yield areas like specialty finance with the need to maintain strong regulatory capital. You can read more about the long-term thinking behind these decisions at Mission Statement, Vision, & Core Values of First Internet Bancorp (INBK).

The table below summarizes the core leverage metrics as the company entered the final quarter of 2025, showing the capital base they are working with post-restructuring.

Liquidity and Solvency

You need to know if First Internet Bancorp (INBK) has the cash to cover its near-term obligations, and the quick answer is yes, their liquidity is strong, but it's been actively managed. For a bank, the traditional Current and Quick Ratios aren't the best measure, because their 'inventory' is loans and their 'payables' are deposits.

Instead, we look at their core funding stability and capital cushion. The strategic balance sheet cleanup in Q3 2025 was a major action that reset their liquidity profile, resulting in a net loss of $41.6 million for the quarter, largely due to a pre-tax loss of $37.8 million on a loan sale. This was a necessary move to clean up their credit profile and enhance long-term flexibility.

Assessing First Internet Bancorp (INBK)'s Liquidity Position

In lieu of a Current Ratio, the key metric for First Internet Bancorp (INBK) is their funding stability. As of September 30, 2025, their loans-to-deposits ratio stood at a favorable 73.9%. That's a solid number, meaning they hold a lot more in customer deposits than they have tied up in loans, which signals strong balance sheet liquidity. Plus, their total cash and unused borrowing capacity was a massive $2.9 billion. That's a huge cushion.

• Loans-to-Deposits Ratio: 73.9% (Q3 2025)
• Cash and Unused Borrowing Capacity: $2.9 billion (Q3 2025)
• Coverage of Uninsured Deposits: 180% (Q3 2025)

Working Capital and Strategic Balance Sheet Trends

The working capital story here isn't about inventory turnover; it's about balance sheet optimization. First Internet Bancorp (INBK) executed a major strategic move in Q3 2025 by selling $836.9 million of single tenant lease financing loans. This reduced their total loan balances by $732.2 million, or 17%, from the previous quarter. They also moved over $700 million of fintech deposits off-balance sheet to manage regulatory capital more defintely. This action reduced risk-weighted assets and improved their regulatory capital ratios, which is a clear, positive signal for long-term solvency.

Cash Flow Statements Overview

Looking at the cash flow statement (CFS), the Trailing Twelve Months (TTM) data through Q3 2025 shows the impact of these strategic shifts. Cash Flow from Operating Activities (CFO) was negative, at -$26.43 million, which is common for a bank actively shifting its balance sheet, as changes in deposits and loans are classified here. On the flip side, Cash Flow from Investing Activities (CFI) was a strong inflow of $251.73 million, largely driven by the proceeds from the major loan sale. This is the cash injection from the balance sheet cleanup.

Liquidity Strengths and Near-Term Actions

The biggest strength is the significant liquidity buffer-$2.9 billion in cash and borrowing capacity-which covers their total uninsured deposits by 180%. That's a huge safety net. The strategic loan sale, while causing a net loss, was a proactive step to address credit issues and reposition the bank for higher-yielding lending, which should lead to net interest margin expansion, forecasted to rise to 2.4%-2.5% (fully taxable equivalent) for Q4 2025. The risk is largely in the credit quality of the remaining small business and franchise finance portfolios, but delinquencies are improving, hitting their lowest level in a year in Q3 2025.

Valuation Analysis

You are looking at First Internet Bancorp (INBK) and asking the right question: is this stock a bargain or a trap? Based on the latest fiscal year 2025 data, the market is pricing First Internet Bancorp (INBK) as a deep-value play, but its valuation ratios signal significant earnings challenges you can't ignore.

The stock is trading near its 52-week low, which is a clear sign of market distress. The share price has plummeted from its 52-week high of around $43.26 to a recent price of approximately $19.30 as of November 2025, representing a drop of over 50%. That kind of price action defintely tells you the market is worried about asset quality and interest rate exposure, which is typical for regional banks right now.

Here's the quick math on the core valuation metrics:

• Price-to-Book (P/B): At just 0.42x, First Internet Bancorp (INBK) is trading at less than half its book value (the theoretical liquidation value of its assets). For a bank, a P/B this low-the industry average is often closer to 1.0x-screams undervalued.
• Price-to-Earnings (P/E): The trailing twelve-month (TTM) P/E ratio is negative (around -4.92) or reported as Not Meaningful (NM), because the company has reported negative earnings per share (EPS). This means the traditional P/E metric is useless for valuation and forces us to rely on book value and forward estimates.
• EV/EBITDA: This metric, Enterprise Value-to-EBITDA, is not typically used for banks, and the data reflects this, often showing as Not Applicable (N/A) or NM. It's a non-starter for this sector.

The low P/B ratio suggests undervaluation, but the negative P/E ratio tells you why: the market is discounting the stock heavily due to current unprofitability. You're buying assets at a discount, but you're also buying into an earnings problem.

Dividend and Analyst Consensus

First Internet Bancorp (INBK) still maintains a dividend, which is a small positive. The forward annual payout is $0.24 per share, giving a forward dividend yield of about 1.28%. However, the TTM payout ratio is a negative percentage (around -6.32%) because of the negative earnings, which means the dividend is not currently covered by profit. The good news is that based on next year's earnings estimates, the payout ratio is forecast to be a sustainable 4.85%, suggesting analysts expect a quick return to profitability.

What this estimate hides is the risk of a prolonged high-interest rate environment further eroding asset values. Still, the dividend is a commitment to shareholders.

Wall Street analysts have a mixed but cautious view. The consensus rating is a 'Reduce,' which is a soft 'Sell,' but the individual ratings tell a more nuanced story. Out of five analysts, there is 1 Buy, 2 Hold, and 2 Sell ratings.

The average 12-month price target is approximately $24.33. Here's the quick math: from the current price of $19.30, that target implies a potential upside of about 26.58%. This suggests that even the cautious analysts believe the stock has significant room to recover once the earnings picture clears up.

The takeaway is simple: First Internet Bancorp (INBK) is cheap on an asset basis (P/B), but it's cheap for a reason (negative P/E). The opportunity lies in the belief that management can quickly restore profitability, which is what the analyst price targets are betting on.

Risk Factors

You need to understand that even with a strong digital model, First Internet Bancorp (INBK) faces clear, near-term headwinds, primarily centered on credit quality and the strategic cost of cleaning up the balance sheet. The biggest risk is the elevated provision for credit losses, which has sharply increased throughout the 2025 fiscal year, directly impacting profitability.

The bank's third-quarter 2025 results show the stark reality: a GAAP net loss of $41.6 million, largely driven by a strategic, but painful, move to manage risk. This loss came despite adjusted total revenue reaching $43.5 million. Here's the quick math: the provision for credit losses jumped to $34.8 million in Q3 2025, a massive increase from $13.6 million in Q2 2025.

Operational and Financial Risk: Credit Quality Deterioration

The core internal challenge is asset quality, specifically within the small business lending and franchise finance portfolios. We've seen a clear trend of deterioration, which management has been actively trying to resolve. For instance, nonperforming loans to total loans rose to 1.00% in Q2 2025, up from 0.80% in Q1 2025.

This credit risk is not just theoretical; it's showing up in the numbers. Net charge-offs to average loans hit 1.89% in the third quarter of 2025. To be fair, this aggressive write-down and provisioning is a necessary step to establish a cleaner credit profile, but it does create a significant short-term earnings drag. The allowance for credit losses to total loans was strategically increased to 1.65% in Q3 2025, up 58 basis points from the prior quarter, which is a defintely prudent move.

External and Strategic Risks

Beyond credit, First Internet Bancorp (INBK) navigates several external risks common to the banking sector, plus a few unique to its digital-first model:

• Economic Uncertainty: Inflationary impacts on small businesses and general economic conditions continue to pressure the lending markets where the bank operates.
• Interest Rate Risk: While the bank has seen net interest margin (NIM) expansion, interest rate fluctuations still pose a risk to funding costs and net interest income.
• Competition and Technology: As a digital bank, it faces intense competition from national institutions and other fintechs. Failure to execute on plans to grow key portfolios, like commercial and industrial or SBA loans, remains a strategic risk.

Mitigation Strategies and Balance Sheet Actions

Management has taken decisive, concrete actions to mitigate these risks, which is what you want to see. The most significant move in 2025 was a strategic balance sheet restructuring in Q3. They completed the sale of $836.9 million of single tenant lease financing loans.

This action, while causing the large net loss, served two critical purposes:

• Capital Enhancement: It strengthened regulatory capital ratios, with the Common Equity Tier 1 ratio improving to 9.24% and the Total Risk-Based Capital ratio reaching 13.11% in Q3 2025.
• Credit Profile Cleanup: The bank took decisive action on problem loans, resulting in a notable improvement in delinquencies, which dropped to 35 basis points in Q3 2025 from 77 basis points in Q1 2025.

Plus, the firm is leveraging its Banking-as-a-Service (BaaS) model and fintech deposits to maintain strong liquidity, with a favorable loans-to-deposits ratio of 73.9% as of Q3 2025.

Your next step should be to monitor the Q4 2025 NIM projection of 2.4% to 2.5% to see if the strategic actions are delivering the expected margin expansion.

Growth Opportunities

You're looking past the recent noise and focusing on the core business, which is smart. First Internet Bancorp (INBK) is fundamentally positioned for a strong rebound in 2026, driven by its digital-first model and a decisive 2025 balance sheet cleanup. The near-term focus on credit risk has suppressed 2025 earnings, but the groundwork is laid for significant net interest margin (NIM) expansion and a return to profitability.

The full-year 2025 consensus revenue estimate sits at about $120.42 million, with an earnings per share (EPS) estimate of just $0.63 per share, reflecting the impact of credit provisions and loan sales. Here's the quick math: management's aggressive action in Q3 2025, including a major loan loss provision of roughly $35 million, was a one-time hit to clear the decks. This sets the stage for a projected 2026 EPS of $5.03 per share, a massive jump as the provision expense normalizes. This is defintely a turnaround story.

Key Growth Drivers and Strategic Moves

The company's growth isn't about opening new branches; it's about digital specialization, which is a key competitive advantage. They are leveraging their original position as an industry pioneer in branchless banking to capture high-growth, specialty finance niches. This strategy is translating into clear, measurable operational improvements.

• Fintech Deposit Growth: Substantial growth in deposits from fintech partnerships has significantly boosted liquidity, improving the loans-to-deposits ratio and lowering funding costs.
• Net Interest Margin Expansion: First Internet Bancorp has achieved eight consecutive quarters of increasing net interest income, a testament to their ability to lower funding costs while increasing asset yields. Management is targeting a fully-taxable equivalent net interest margin (FTE NIM) of 2.30-2.35% by the end of Q4 2025.
• Balance Sheet Optimization: The Q3 2025 sale of $836.9 million in single tenant lease financing loans was a strategic move to enhance regulatory capital ratios. This boosted their Common Equity Tier 1 ratio to 9.24%, providing flexibility for future growth.

Product Innovation and Future Projections

Their competitive edge is rooted in technology and specialized lending. For example, the partnership with Increase to deliver High-fidelity ACH-a solution for faster, more reliable electronic funds transfer-won an American Banker's 2025 Innovation of the Year Award. This focus on innovation in core payment infrastructure matters more than any vague promise of a cutting-edge solution.

What this estimate hides is the management's clear goal: achieving a Return on Average Assets (ROAA) of 1%, a target that signals a return to top-tier bank profitability. The strong loan pipelines in commercial real estate, construction, and commercial and industrial balances, which drove total commercial loan balances to $3.5 billion as of June 30, 2025, will fuel this growth.

The market is already pricing in a much better 2026, with a consensus revenue estimate of $152.26 million. The tangible book value per share, despite the Q3 clean-up, stood at $39.88, offering a margin of safety for investors willing to look past the short-term credit noise.
