Frequently asked questions
What is NorthWestern Corporation's revenue?
NorthWestern Corporation's trailing twelve-month revenue is $1.64B. 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 NWE?
In its most recent fiscal year, NWE ran a gross margin of 82.31%, an operating margin of 20.23%, and a net margin of 11.24%. 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 NWE generate?
NWE produced $-130.00M 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 NWE's balance sheet healthy?
NWE holds $8.78M in cash and equivalents against $3.18B in long-term debt, on $2.89B of shareholder equity. That debt is best read against the cash flow the business throws off each year.
