What does halt code T12 mean? Additional Information Requested
The exchange has asked the company for information and stopped trading until it gets an answer.
What triggers it
Usually the exchange seeking clarification about news, unusual activity, or a filing. It is an exchange-initiated halt rather than a company-initiated one.
What happens next
Resolution depends on the company responding, so these are open-ended and can run long. Treat the resume time as unknown rather than imminent.

T12 halts: common questions
- What does halt code T12 mean?
- The exchange has asked the company for information and stopped trading until it gets an answer. On the halt feed it shows as "Additional Information Requested".
- How long does a T12 halt last?
- We have seen 20 T12 halts but only 1 with a published resume time, which is fewer than the 5 we require before quoting a median. Publishing one from that would be a guess dressed as a measurement. The exchange sets the resume time and announces it on the halt feed.
- What triggers halt code T12?
- Usually the exchange seeking clarification about news, unusual activity, or a filing. It is an exchange-initiated halt rather than a company-initiated one.
- What happens when the T12 halt lifts?
- Resolution depends on the company responding, so these are open-ended and can run long. Treat the resume time as unknown rather than imminent.
- Can I trade a stock while it is halted?
- No. A halt stops trading on every US exchange at once, so no orders execute until the stock reopens. Orders can still be placed and cancelled, and the reopening auction can print well away from the last traded price.
