Frequently Asked Questions
What is TTEK's after-hours price?
Tetra Tech (TTEK) is trading at $38.97 after hours, up $0.14 (0.36%) from its regular-session close of $38.83.
Why is TTEK moving after hours?
TTEK is up 0.36% 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 TTEK after-hours trading start and end?
After-hours trading in TTEK on the NASDAQ 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 TTEK's after-hours move hold at the open?
An after-hours move that carries into the next session becomes an opening gap, and TTEK's gap history is the best guide to what happens next: 0% of TTEK 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 TTEK report earnings?
TTEK reported earnings on Nov 11, 2026 after the close, with an estimated EPS of $0.47. Earnings are the most common cause of a large after-hours move, since most companies report after the close.
