Frequently asked questions
What is First Interstate BancSystem Inc's revenue?
First Interstate BancSystem Inc's trailing twelve-month revenue is $1.04B. Revenue is the top line the whole model builds on, and at this scale the question shifts from how fast it grows to whether margins hold as it compounds.
How profitable is FIBK?
In its most recent fiscal year, FIBK ran a gross margin of 97.47%, an operating margin of 37.01%, and a net margin of 28.55%. Margins this high mean most of each extra dollar of revenue drops through to profit, which is the signature of real pricing power.
How much free cash flow does FIBK generate?
FIBK produced $277.80M in free cash flow in its most recent fiscal year. Free cash flow is what is left after running and reinvesting in the business, and it is the cash that actually funds buybacks, dividends, and a stronger balance sheet.
Is FIBK's balance sheet healthy?
FIBK holds $358.20M in cash and equivalents against $295.40M in long-term debt, on $3.45B of shareholder equity. Cash on hand exceeds long-term debt, so the balance sheet adds little financial risk to the thesis.
