🟢 Cardinal Infrastructure Group is trading 11.75% up in after-hours trading

Cardinal Infrastructure Group is trading at $16.36, up 11.75%, with no confirmed company-specific catalyst identified for its after-hours rise.

• An October 21 law-firm notice publicized an investigation tied to the company’s August 11 second-quarter results and margin disclosures; it does not establish that the notice drove the move.
• Major indexes closed higher, while U.S. futures pointed lower. No verified news directly connects those conditions to the stock’s after-hours gain.
