Values are as tagged by the issuer in XBRL. Revenue for banks and insurers is net of interest expense where that is the reported line. Fiscal years that do not follow the calendar are shown by their period-end date. No price, market cap, or valuation multiple is shown because Yield Theory does not republish unlicensed market data.

Diluted EPS is the earnings figure behind the price-to-earnings ratio; the P/E multiple compression calculator shows how a change in that multiple moves a share price. Shares outstanding multiplied by the share price gives market capitalization.

What investors should watch in ATO

Atmos Energy Corporation sits in Utilities. Regulated power and water — bond-like income proxies whose relevance is being reshaped by data-center and electrification demand. We have not yet written company-specific drivers for ATO; the forces that matter most for the sector are:

  • ◆Interest rates and dividend-yield competition
  • ◆Data-center and AI electricity demand
  • ◆Rate-case outcomes and regulation
  • ◆The grid buildout and energy transition

Key questions for the ATO thesis

Each question starts with what the filings show, then why it matters. None of these is a rating or a forecast.

Does ATO's reported profit turn into cash?

Operating cash flow was $2.0B, 1.71 times net income of $1.2B, for the fiscal year ended September 30, 2025.

Cash from operations exceeded reported earnings. Non-cash charges such as depreciation, amortization and stock-based compensation usually explain the gap; the cash-flow statement shows which.

How much of ATO's revenue is left as profit?

Net income was 25.5% of revenue for the fiscal year ended September 30, 2025, based on revenue and net income reported for the same period.

Net margin reflects the business model as much as execution, so compare it with companies in the same SEC industry and read the income statement for one-time items before treating it as a run rate.

When does Atmos Energy Corporation's fiscal year end?

The SEC lists Atmos Energy Corporation's fiscal year end as September 30, not December 31. The latest annual figures here run from October 1, 2024 to September 30, 2025.

Annual results cover a different 12 months from calendar-year peers. Align periods before comparing growth or margins across companies.
