The three LBRDA-related tickers (LBRDA, LBRDK, LBRDP) were also halted for T12 additional information requested, indicating an ongoing regulatory review.

What Is an LULD Halt?
A LULD halt pauses trading when a stock's price moves more than a defined percentage away from its recent five-minute average. The bands are 5% for most large-cap S&P 500 names, 10% for smaller stocks, and 20% for stocks under $3. Most LULD halts last five minutes.
What Does a T1 Halt Mean?
A T1 halt is a regulatory pause pending the release of material news. It has no fixed duration and resumes when the exchange determines an orderly market can be maintained.
Halt Code Reference

| T2 | News released | Trading halted pending the release of material news; resumption follows news dissemination. |
| T12 | Additional information requested | Exchange requests additional information from the issuer; halt can extend for days. |
