🔴 Allegheny Technologies is trading 19.9% down in after-hours trading — no reliable company-specific catalyst identified

Allegheny Technologies is trading at $181.90 (-19.90%) in after-hours trading, with no reliable August 13 company-specific announcement or late-breaking catalyst identified.

• The regular session closed at $227.08 on August 13, 2026.
• Recent Q2 results were positive, including $1.23 adjusted EPS, $1.26 billion revenue, and raised guidance, making them unlikely to explain the decline.
• Broader indexes finished higher, so the move does not align with overall market direction.
