Frequently asked questions
What is Atmos Energy Corporation's revenue?
Atmos Energy Corporation's trailing twelve-month revenue is $4.88B, and consensus projects about $7.31B by 2030. 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 ATO?
In its most recent fiscal year, ATO ran a gross margin of 52.37%, an operating margin of 33.17%, and a net margin of 25.49%. 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 ATO generate?
ATO produced $-1.51B 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 ATO's balance sheet healthy?
ATO holds $203.80M in cash and equivalents against $8.98B in long-term debt, on $13.56B of shareholder equity. That debt is best read against the cash flow the business throws off each year.
