Atmos Energy Corp (NYSE: ATO) is a natural gas utility company that distributes and transports natural gas to customers across its regulated service territories. It makes money through cost-based, rate-regulated tariffs set by state regulatory commissions, which allow recovery of operating costs plus a permitted rate of return. Distribution and pipeline operations are subject to rate cases filed with regulators in the states where Atmos operates, with recent rate case filings covering Texas, Kentucky, and Virginia divisions (FY2025). Operating revenues were $4.43 billion in FY2025 and $3.92 billion in FY2024, with net income of $746.8 million in FY2025 and $671.4 million in FY2024.

The business is capital-intensive, with significant annual capital expenditures reflected in the cash flow statement, and is a dividend-paying, debt-carrying utility operating under traditional regulated-utility economics.
