FIBK Q2: $0.87 EPS Hides a Shrinking Loan Book-Deposit Fix Is Helping, but Not Forever

First Interstate's Q2 Beat Was Real, but the Balance Sheet Is Still Being Rebuilt

First Interstate's second quarter was not hard to understand: $0.87 per diluted share and a stronger quarter-over-quarter profit picture. The harder question is whether that beat deserves the stock's recent rerating, or whether investors are rewarding a transition phase before the loan book has clearly stabilized.

The earnings jump came with a caveat

On the surface, the quarter looks clean. First Interstate reported $0.87 per diluted share on net income of $83.9 million, up from $60.2 million in the first quarter. That improvement fits the case that balance-sheet cleanup is lifting profitability even as the franchise stays smaller for now.

But this was not a pure core-earning surge. The quarter also included a $19.5 million gain from a branch transaction, which means part of the earnings lift came from right-sizing the footprint, not only from stronger lending activity.

The recent rerating already reflects some optimism

That distinction matters because investors have already rewarded part of the story. FIBK has posted a 35.59% one-year total return, so some of the "cleanup is working" narrative is already in the price. The debate now is less about whether the quarter was solid and more about whether the remaining runoff is improving the balance sheet or simply compressing it too fast.

Net Interest Margin Expanded Because Funding Improved Faster Than Assets Shrunk

First Interstate did not need loan growth to produce a better quarter. It needed the balance sheet to get cheaper and better mixed faster than it got smaller.

A smaller loan book can still support spread income

Even with lower interest-earning assets, the bank still generated net interest income of $202.2 million, while fully taxable equivalent net interest margin rose to 3.48%. The lesson is straightforward: a smaller earning-asset base can still support spread income if asset yields hold and funding costs keep improving.

Margin expansion was not a one-quarter accident

This was not a lucky quarter. First Interstate posted its ninth consecutive quarter of margin expansion. Average loan yields rose two basis points sequentially, while total funding costs fell four basis points. Those moves are small in isolation, but banks live on thin spreads, so even a few basis points can matter.

There is also an important mix angle. Management highlighted deposit mix improvements, and total deposit costs declined three basis points. That does not prove every weaker loan left at the same pace, but it does suggest the bank is becoming more selective on both sides of the balance sheet: less profitable credits are exiting while cheaper funding is helping support the model.

What can sustain the trend-and what can break it

Investors should not assume margin can expand forever based on one quarter. Two temporary factors helped: an additional accrual day boosted net interest income, and the balance sheet was still adjusting to the branch sale completed in April.

The more durable point is that management said proactive management of loan payoffs and deposit mix helped offset pressures from declining overall loan balances. If that mix improvement continues while asset-quality runoff cools, the quarter looks more durable. If margin gains reverse before the loan book steadies, this quarter may look more like a transition peak than a new baseline.

The Real Debate Is Loan Runoff Quality and Funding Discipline

The split among investors is not about whether First Interstate earned $0.87 diluted EPS. It is about whether the bank is pruning the loan book the right way while making the funding base strong enough to outlast the cleanup.

What supports the bullish read

• Management said the quarter benefited from targeted reductions in criticized and non-core loans. That supports the view that runoff is improving balance-sheet quality, not just shrinking the franchise.
• The funding story looks constructive, not random. Management highlighted continued improvement in the underlying profitability of the balance sheet, and capital returns show confidence in the position. First Interstate has seen dividend and buyback activity alongside the cleanup.
• If management's view that the balance sheet is working through a runoff phase and can stabilize soon proves right, investors may start paying for normalization rather than only for triage.

What supports the cautious read

• The quarter still reflected elevated loan payoffs and a larger-than-expected decline in reported loan balances. If runoff continues to outpace production, today's margin gains may not be enough for long.
• A stock that has delivered a 35.59% one-year total return deserves closer scrutiny. The market is no longer assuming the cleanup is risk-free.
• Credit remains a watchpoint. Higher loan charge offs add a layer of risk, so the business model needs cleaner assets, not just cheaper funding.

What would change the story

• The clearest positive catalyst is clearer balance-sheet stabilization as runoff runs its course and funding mix keeps improving.
• The clearest warning sign is margin reversal before deposit costs and loan yields settle.
• Capital returns should be treated as a confidence signal, not the core thesis. They matter because they suggest strength, but they do not replace the need for healthier loans and cheaper deposits.

Rule of thumb: if First Interstate can keep deposit mix improving while criticized and non-core loans stop dominating runoff, the cleanup can justify a higher valuation. If shrinkage outruns production before funding quality fully stabilizes, the recent rerating may have moved ahead of the evidence.

What to Watch Next in FIBK

The stock has already had its 35.59% one-year total return, so the next step is to focus on confirmation rather than narrative.

The key signals

• Watch whether the ninth consecutive quarter of margin expansion continues. Ongoing margin improvement would suggest the smaller balance sheet is becoming a better one.
• Watch deposit mix and deposit costs. Continued improvement would support the view that funding is helping offset loan runoff.
• Watch credit quality. The quarter already flagged higher loan charge offs as a risk, and that risk matters more if balance-sheet shrinkage persists.

If margin expansion, deposit improvement, and loan runoff quality all line up, the bull case gets stronger. If those trends unwind, this quarter will look more like peak transition than durable recovery.
