Among Swoopr's S&P 500 Equal Weight companies, 10 others share that classification; by latest reported revenue, Atmos Energy ranks 3 of 11. A filing classification is a starting point: a company's real competitors depend on its segments, which its 10-K describes.

Revenue growth compares each company's latest fiscal year with the one before. Fiscal years do not always end on the same date, so treat close comparisons with care.
How Does Atmos Energy Rank Among All SEC Filers in Its Industry Code?
11 companies with annual reports in Swoopr's SEC dataset share SIC code 4924 (Natural Gas Distribution), a wider group than the S&P 500 Equal Weight companies above. Ranks run from 1 (highest) and use each company's latest fiscal year, in U.S. dollars.
| Measure | Atmos Energy | Median of filers | Rank |
|---|---|---|---|
| Revenue | $4.7 billion | $2.3 billion | 3 of 11 |
| Revenue growth | 12.9% | 11.4% | 5 of 10 |
| Operating margin | 33.2% | 27.4% | 5 of 10 |
| Net margin | 25.5% | 13.6% | 2 of 11 |
A SIC code reflects the filer's main business as the SEC records it, so the group mixes companies of very different size; the median is a better guide than the average, and a rank near the top by revenue says nothing about quality.
Where These Numbers Come From
Every figure on this page is a value Atmos Energy reported in its own SEC filings, read from the SEC's XBRL data (accession 0000731802-25-000056 for fiscal year 2025). Ratios are computed from those reported values. Figures were retrieved on October 12, 2026; a later amendment or a new annual report can change them, and the filing itself always takes precedence over this summary.
Each fiscal year is labeled by the calendar year in which it ended, so a company that names the same period differently in its own filings (many retailers whose year ends in January) may use another label. A year is left out of the table when the SEC data set holds no value for it. A figure shown as "Not reported" means the company did not file a value under the standard tag Swoopr reads, not that the amount was zero. This page is educational and describes reported history only; it is not a forecast or a recommendation.
