Frequently asked questions
What is Black Hills Corporation's revenue?
Black Hills Corporation's trailing twelve-month revenue is $2.29B. 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 BKH?
In its most recent fiscal year, BKH ran a gross margin of 38.47%, an operating margin of 23.27%, and a net margin of 12.62%. 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 BKH generate?
BKH produced $-146.40M 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 BKH's balance sheet healthy?
BKH holds $182.80M in cash and equivalents against $4.70B in long-term debt, on $3.82B of shareholder equity. That debt is best read against the cash flow the business throws off each year.
