🔴 Merck is trading 3.86% down in after-hours trading — catalyst remains unclear

Merck is trading at $125.87, down -3.86% in after-hours trading, with no new August 10, 2026 company-specific announcement clearly explaining the decline.

• Merck’s recent second-quarter results included a $5.7 billion Terns acquisition charge, producing a $0.13 non-GAAP loss per share.
• The results release was issued August 4, not August 10.
• Broader markets were mostly flat, so recheck for delayed news.
