## Geography

First Interstate operates primarily in 12 U.S. states, with 289 banking offices as of year-end 2025 and a footprint concentrated in the Mountain West and Upper Midwest. The company has been pruning non-core markets, including the divestiture of Arizona and Kansas operations and planned Nebraska branch sales/closures, while reinvesting in markets where it has stronger density and franchise value.

- **United States** (100%) — All operations and revenue are U.S.-based; the company does not disclose country-level revenue split.

- Operates 289 banking offices across 12 U.S. states
- Core footprint includes Montana, Idaho, Wyoming, the Dakotas, and neighboring states
- Exited Arizona and Kansas to sharpen market focus
- Nebraska branch sales and closures reduce lower-priority exposure
- Branch density matters because community banking depends on local relationships

## Strategy

The company is focused on disciplined organic growth, deeper client relationships, and better core profitability rather than broad geographic expansion. Management is also optimizing the branch network, reallocating capital to stronger markets, and improving credit processes, risk culture, and balance-sheet mix to support earnings through rate and cycle volatility.

- **Relationship-driven organic growth** (medium-term) — The bank wants to grow within existing markets where it already has local franchise strength.
- **Footprint optimization** (short-term) — Closing or selling weaker branches frees capital and management attention for better markets.
- **Balance-sheet and margin management** (short-term) — Funding mix and rate sensitivity are central to bank profitability.
- **Credit and risk discipline** (medium-term) — Tighter underwriting and risk culture help protect asset quality in a competitive lending market.

- Deepen full-client relationships across deposits, lending, and fees
- Refocus capital on markets with stronger brand density and growth potential
- Optimize the branch network by exiting weaker or non-core markets
- Improve credit processes and risk culture
- Manage funding mix and asset-liability sensitivity to protect margin

## Risks

The main risks are credit quality, funding and interest-rate sensitivity, and intense competition from banks, credit unions, fintechs, and nonbank lenders. The company also faces regulatory, cybersecurity, vendor, and reputation risk, which are especially important because its model depends on trust, branch relationships, and third-party service providers.

- **Credit deterioration in local lending portfolios** [high] — Community banks are exposed to borrower performance in their local markets and industries.
- **Net interest margin compression** [high] — Funding costs and asset repricing can move faster than loan yields in changing rate environments.
- **Competitive pressure on pricing and market share** [medium] — The bank competes with larger banks, credit unions, fintechs, and nonbank lenders.
- **Cybersecurity and third-party vendor risk** [high] — Digital banking and outsourced services increase exposure to data breaches and supply-chain attacks.
- **Regulatory and compliance changes** [medium] — Banks operate under extensive federal and state oversight that can affect products and costs.

- Credit losses could rise if local economies weaken or borrower quality deteriorates
- Competition can pressure loan pricing, deposit costs, and fee income
- Interest-rate moves can compress net interest margin and funding spreads
- Cybersecurity and vendor incidents can disrupt operations and damage trust
- Regulatory changes can raise compliance costs and constrain products

## Accounting

For a bank, the most important accounting judgments are loan-loss estimates, fair value measurements, and goodwill impairment from acquisitions. First Interstate also has meaningful estimate sensitivity in asset-liability management, vendor-related contingencies, and branch/network restructuring decisions that can affect charges, asset values, and comparability across periods.

- **Allowance for credit losses** — Can materially change provision expense and earnings volatility
- **Goodwill impairment** — Could create noncash charges if franchise value declines
- **Fair value measurements** — Can move other income and balance-sheet carrying values
- **Branch divestitures and closures** — Affects comparability of operating expenses and noninterest income

- Allowance for credit losses depends on borrower and macro assumptions
- Goodwill is tested annually and can create impairment charges after acquisitions
- Fair value estimates affect securities, acquired assets, and purchase accounting
- Branch sales and closures can create restructuring and disposal gains/losses
- Deposit and loan mix influence interest income recognition and margin trends
