StockStory’s Take

First Interstate BancSystem’s fourth quarter results surpassed Wall Street’s expectations for both revenue and adjusted earnings, yet the market responded negatively, reflecting concerns raised during the earnings call. Management attributed the quarter’s performance to ongoing branch divestitures and a strategic shift away from non-core loan portfolios, both of which were designed to improve core profitability and optimize the company’s geographic footprint. CEO James Reuter highlighted, “We made meaningful progress to improve core profitability, refocus capital investment and optimize our balance sheet through reorienting our footprint to geographies where we have brand density, strong market share and high potential for growth.”

Looking ahead, management emphasized that future performance will be driven by a flatter organizational structure, disciplined credit management, and targeted investments in growth markets such as Colorado and Montana. CFO David Della Camera noted that margin expansion will depend on the pace of reinvesting maturing loans and securities at higher rates, as well as the success of new relationship banking initiatives. Management remains cautious about loan growth in the near term, but anticipates improved activity as recent organizational changes take effect, stating, “Our guidance has an underlying assumption that loans declined in the first half of the year while modestly growing in the back half.”

Key Insights from Management’s Remarks

Management pointed to branch sales, strategic loan runoff, and cost optimization as pivotal to both the quarter’s financial results and the company’s evolving strategy, while emphasizing the importance of operational changes and talent upgrades.

• Branch divestitures and consolidation: The company exited several markets, completing branch sales in Arizona and Kansas and announcing further sales and closures in Nebraska, North Dakota, and Minnesota. These moves are part of a broader effort to focus on states with stronger potential for growth and to improve operational efficiency.
• Shift away from non-core lending: First Interstate intentionally allowed certain large transactional and indirect lending loans to run off, prioritizing full banking relationships that include both deposits and fee-generating services. The outsourcing of its consumer credit card product was another step toward refocusing on core competencies.
• Organizational restructuring: The bank transitioned to a flatter structure, replacing regional layers with state-level leadership and elevating both internal and external talent. Management expects this change to speed up decision-making, improve customer experience, and support organic growth.
• Share repurchase program expansion: The company repurchased approximately 3.7 million shares in 2025 and increased its buyback authorization to $300 million, signaling capital allocation priorities amid ongoing optimization efforts. Management described share repurchases as the immediate capital allocation priority.
• Credit quality improvements: Proactive credit management led to a reduction in criticized loans and non-performing assets, though net charge-offs were elevated by a single large credit event. Management views credit stabilization as an important outcome of its recent strategic initiatives.

Drivers of Future Performance

Management’s outlook for the coming year centers on margin expansion from loan repricing, continued branch optimization, and disciplined cost management, while acknowledging headwinds from flat loan growth and market competition.

• Net interest margin expansion: Management expects sequential improvement in net interest margin as older, lower-yielding loans mature and are replaced with higher-yielding assets, provided a supportive interest rate environment persists. The pace of margin growth will rely on the bank’s ability to attract new customer relationships and maintain pricing discipline in a competitive market.
• Disciplined expense management: The company plans for flat to slightly lower expenses in the coming year, even as it reinvests in growth initiatives such as hiring new relationship managers, opening branches in targeted markets, and increasing advertising spend. However, normalization of certain costs, like medical insurance, could result in a modest year-over-year expense increase.
• Focus on relationship banking and geographic densification: The bank’s strategic focus on building full customer relationships in core markets, particularly in Colorado and Montana, is expected to gradually offset loan runoff. Management highlighted the importance of organic growth and brand density, but acknowledged that loan growth could remain subdued in the first half of the year before picking up later.

Catalysts in Upcoming Quarters

In the coming quarters, our analysts will be closely monitoring (1) execution of branch sales and additional network consolidation, (2) the effectiveness of the new organizational structure in accelerating loan growth and customer engagement, and (3) progress in net interest margin expansion as loan repricing continues. We will also track credit quality metrics and the pace of share repurchases as key indicators of management’s ability to deliver on strategic priorities.
