What is TNDM's after-hours price?
Tandem Diabetes Care (TNDM) is trading at $16.94 after hours, up $0.13 (0.75%) from its regular-session close of $16.81.
Why is TNDM moving after hours?
TNDM is up 0.75% 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 TNDM after-hours trading start and end?
After-hours trading in TNDM 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.
When does TNDM report earnings?
TNDM is expected to report earnings around Nov 5, 2026 after the close (estimated), with an estimated EPS of $-0.26. Earnings are the most common cause of a large after-hours move, since most companies report after the close.
