FIBK Stock Forecast & Price Target

First Interstate BancSys is benefiting from improving core profitability as 3Q net interest margin expanded to 3.55%, core NIM reached 3.51%, and FTE NII of $207.3 million beat expectations, while management still sees continued margin expansion supported by higher loan yields, repricing, and securities cash flows. The company also showed disciplined execution in noninterest items, with core fee income of $43.3 million and core expenses of $157.2 million both beating forecasts, while 2026 guidance narrowed to $814 million-$819 million for NII and ~$629 million-$635 million for expenses. Fundamentally, a reset credit culture under new leadership has helped criticized assets crest and NCOs decline, asset sales and the exit from indirect lending improved focus, and roughly 6 million shares repurchased for about $200 million underscores confidence in capital strength and organic growth.

First Interstate BancSys is viewed negatively because its earlier M&A-heavy strategy delivered weak organic expansion, with average loan growth of just 2.7% annually from 2015-2024 while credit quality deteriorated as NPAs, criticized assets, and NCOs rose from 2020-2024. Its profitability and capital efficiency also lagged peers, as TBV growth and ROA trailed despite the company’s operating footprint, and buybacks were not consistently used to support shareholder returns. Although the stock rose 33% in the trailing 12 months and outpaced the KRX by 13%, expectations have reset higher while the firm’s 2027 outlook of 4.0% net loan growth, 1.05% ROA, and 13.9% ROTCE still trails peer medians.
