Dallas, Texas-based Atmos Energy Corporation (ATO) is a fully regulated natural gas utility headquartered in Dallas, Texas. One of the largest natural-gas-only distributors in the U.S., the company serves approximately 3.4 million residential, commercial, public-authority, and industrial customers across eight states, primarily in the South.
With a market cap of $28.3 billion, the company falls in the “large-cap stocks” category, specifically reserved for stocks with a market cap between $10 billion and $200 billion. Atmos Energy’s competitive strengths stem from its large regulated natural-gas distribution network, strong presence in growing Southern U.S. markets, and predictable utility earnings. Its extensive infrastructure, scale, and long-term customer relationships create meaningful barriers to entry, while ongoing investment in pipeline and system modernization supports reliable service and steady rate-base growth.
