Understand First Interstate BancSystem, Inc.: how it makes money

First Interstate BancSystem operates First Interstate Bank, taking deposits and making loans (including real estate and consumer loans) and earning money from the lending and deposit spread, with profitability also affected by credit performance (such as non-performing and criticized loans).

As a traditional bank, its profit engine depends on how much it can fund and place Loans Held for Investment relative to Deposits (Loans Held for Investment to Deposits Ratio: 67.3%), while credit health (Non-Performing Assets and Criticized Loans) influences losses that can reduce returns.
