Atmos Energy Corporation (ATO) valuation and DCF model

What the price implies · reverse DCF

At $175.23 the price implies revenue of $72.02 billion by year ten, growing 30.8% a year, at a 10% free-cash-flow margin then.

The headline discounts the last twelve months’ free cash flow after share-based pay at 9.0% for ten years and grows it 2.5% a year after that, the same for every company, so the figure compares across the market (how a reverse DCF works).

Base case on its own ten-year record Atmos Energy Corporation’s own growth, carried forward

Its assumptions

Powerpack lets you start from a scenario and type over any of them.

The base case’s inputs, which Powerpack lets you change
1 · Revenue and margin
the four quarters to June 2026, from the 10-Q and 10-K filings

Yearly growth in revenue. It usually slows as the company matures.

2 · Rates

Cost of equity is the yearly return shareholders require, typically 8–11%. Terminal growth is growth forever after year 10, usually near long-run inflation, 2–3%.

3 · Per share

Diluted shares outstanding. Net debt, under Advanced inputs, is taken off before dividing.

ATO trades at 15.22× EV/EBITDA, against a 10-year average of 13.78× (range 11.56×–15.76×). That is dearer than 89% of the last 9 year-end readings; re-rating to the average implies $153.02 per share.

Every growth rate on this page is the business’s — its cash flow, FFO or dividend — never its share price’s. A discounted-cash-flow model is only as good as its assumptions. Figures from the 10-K and 10-Q filings. Not investment advice.
