StockStory’s Take

First Interstate BancSystem’s second quarter performance reflected the company’s ongoing focus on balance sheet optimization and relationship-driven growth. Management attributed the quarter’s results to net interest margin expansion, disciplined expense management, and targeted reductions in criticized and non-core loans. CEO Jim Reuter described the franchise as more efficient, highlighting progress in digital engagement, operating model updates, and the successful execution of a share repurchase program. The company’s proactive approach to managing loan payoffs and deposit mix helped offset pressures from declining overall loan balances, particularly through efforts in the Rocky Mountain region and enhanced core deposit growth.

Looking ahead, management expects continued variability in reported loan balances, driven by accelerated payoffs in non-relationship and out-of-market credits, as well as ongoing efforts to strengthen the deposit base. CFO David Della Camera emphasized that the recent organizational changes and addition of relationship managers are supporting increased loan production pipelines, though near-term growth will be tempered by further portfolio clean-up. The company anticipates that fixed asset repricing and a favorable shift in deposit costs will provide incremental benefits to net interest margin, with Reuter underscoring the intent to maintain a disciplined focus on capital allocation, stating, "Our focus remains on the long-term drivers of franchise value, which are deepening customer relationships, growing numbers of clients and core deposits, improving credit quality, optimizing our operating model and deploying capital in a disciplined manner."

Key Insights from Management’s Remarks

Management pointed to a combination of net interest margin improvement, disciplined portfolio management, and ongoing investments in technology and personnel as the primary drivers of the latest quarter’s performance.

• Net interest margin expansion: The company achieved its ninth consecutive quarter of net interest margin growth, driven by fixed asset repricing and lower funding costs, despite a reduction in interest-earning assets due to branch sales and loan payoffs.
• Loan portfolio repositioning: Elevated loan payoffs, especially in non-relationship and criticized credits, led to a decline in total loan balances. Management characterized these payoffs as largely non-core, helping to de-risk the balance sheet and improve overall credit quality.
• Deposit mix improvement: While total deposits declined, the mix shifted toward more stable, noninterest-bearing balances. Management allowed higher-cost deposits to exit, focusing on core relationship growth and a more favorable funding profile.
• Operational efficiency gains: The company continued realigning staffing levels, prioritizing revenue-generating positions and leveraging technology to improve efficiency. This included a completed organizational redesign and the addition of 14 new relationship managers to support production in key markets.
• Capital deployment and shareholder returns: Share repurchases remained a core capital strategy, with the authorization increased by $150 million. The dividend was maintained, and management highlighted a strong capital position, with a common equity Tier 1 ratio of 14.54%, supporting both growth initiatives and ongoing shareholder returns.

Drivers of Future Performance

Management expects future performance to be shaped by ongoing loan portfolio clean-up, efforts to deepen core customer relationships, and benefits from fixed asset repricing.

• Continued loan payoff activity: Management anticipates further accelerated payoffs of non-relationship and out-of-market loans, which will suppress near-term reported loan growth but are expected to strengthen the long-term quality of the loan book.
• Deposit growth and mix shift: Focus remains on growing core, low-cost deposits, with management citing improvements in noninterest-bearing balances and ongoing customer acquisition as key to maintaining a stable funding base and supporting future lending.
• Margin and earnings profile improvement: The company expects sequential improvement in net interest margin and profitability through fixed asset repricing and lower deposit costs, with the potential for additional upside as new relationship managers contribute to loan production and as asset mix stabilizes.

Catalysts in Upcoming Quarters

In the coming quarters, the StockStory team will be monitoring (1) the pace and composition of loan payoffs and whether relationship-driven loan production can offset runoff; (2) sustained improvement in core, low-cost deposit growth as higher-cost funding exits the balance sheet; and (3) progress from recent investments in technology, branding, and new relationship managers. Additionally, we will watch for signs that margin expansion and operational efficiencies translate into higher returns and improved profitability.
