🟢 Calix is trading 44% up in after-hours trading; no verified catalyst identified

Calix is trading 43.87% higher at $50.57 after-hours on September 22, 2026, with no verified company-specific catalyst explaining the move.

• The regular-session close was $35.15.
• Calix’s September 17 official release announced expanded AI workflows. A September 22 law-firm investigation notice concerned potential fiduciary-duty breaches; neither source directly linked to the surge.
• Broader indexes were mixed, so market direction does not explain the magnitude.
