Frequently Asked Questions
What is ATO's after-hours price?
Atmos Energy (ATO) is trading at $157.16 after hours, down $0.01 (0.00%) from its regular-session close of $157.17.
Why is ATO moving after hours?
ATO is down 0.00% in after-hours trading. Moves in this session almost always follow something released after the 4:00 PM ET close — an earnings report, guidance, a filing, or news — and trade on far thinner volume than the regular session, so the size of the move can overstate what the market will settle on at the next open.
When does ATO after-hours trading start and end?
After-hours trading in ATO on the NYSE runs from 4:00 PM to 8:00 PM ET on trading days, immediately after the regular session closes. Not every broker offers the full window, and liquidity thins sharply after about 6:30 PM ET.
Will ATO's after-hours move hold at the open?
An after-hours move that carries into the next session becomes an opening gap, and ATO's gap history is the best guide to what happens next: 0% of ATO gap-ups have fully filled over the past 5 years. Fill rates this high mean a large after-hours move is more often faded than extended.
When does ATO report earnings?
ATO is expected to report earnings around Nov 4, 2026 after the close (estimated), with an estimated EPS of $1.15. Earnings are the most common cause of a large after-hours move, since most companies report after the close.
