--- title: "Atmos Energy: Competitors" description: "Atmos Energy compared with companies that share its SEC industry classification: revenue, growth and margins from SEC filings, and how the peer group is chosen." canonical: https://www.getswoopr.com/stocks/companies/atmos-energy/competitors/ source: "Swoopr Investment: https://www.getswoopr.com" --- # Atmos Energy: Competitors & Industry Structure ## Direct Answer SEC EDGAR classifies Atmos Energy under SIC code 4924 (Natural Gas Distribution). 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. ## How Does Atmos Energy Compare With Its Peers? | Company | Revenue (latest FY) | Revenue growth | Operating margin | Net margin | | --- | --- | --- | --- | --- | | [Cheniere Energy Inc.

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. ## Frequently Asked Questions ### Who are Atmos Energy's competitors?
