Frequently asked questions
What is Northwest Natural Gas Co's revenue?

How profitable is NWN?
In its most recent fiscal year, NWN ran a gross margin of 39.56%, an operating margin of 31.38%, and a net margin of 8.79%. 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 NWN generate?
NWN produced $-197.77M 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.
