Frequently Asked Questions
What is AM's after-hours price?
Antero Midstream (AM) is trading at $20.36 after hours, up $0.01 (0.02%) from its regular-session close of $20.36.
Why is AM moving after hours?
AM is up 0.02% 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 AM after-hours trading start and end?
After-hours trading in AM 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 AM's after-hours move hold at the open?
An after-hours move that carries into the next session becomes an opening gap, and AM's gap history is the best guide to what happens next: 100% of gap-downs have filled over the past 5 years. Fill rates this high mean a large after-hours move is more often faded than extended.
When does AM report earnings?
AM is scheduled to report earnings on Oct 28, 2026 after the close (confirmed), with an estimated EPS of $0.27. Earnings are the most common cause of a large after-hours move, since most companies report after the close.
