Frequently asked questions
What is One Gas Inc's revenue?
One Gas Inc's trailing twelve-month revenue is $2.32B. 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 OGS?
In its most recent fiscal year, OGS ran a gross margin of 58.85%, an operating margin of 18.85%, and a net margin of 10.88%. 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 OGS generate?
OGS produced $-128.39M 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 OGS's balance sheet healthy?
OGS holds $33.73M in cash and equivalents against $2.36B in long-term debt, on $3.44B of shareholder equity. That debt is best read against the cash flow the business throws off each year.
