🔴 S&P Global is trading 7.4% down in after-hours trading — no clear company-specific catalyst identified

S&P Global is trading 7.4% down at $375.28 after no clear September 18, 2026 company-specific catalyst was identified.

• The September 17 OpenZeppelin acquisition announcement was previously disclosed; financial terms remain undisclosed, and no material impact on results is expected.
• The broader market was mixed-to-positive, so index sentiment does not clearly explain the sharp decline.
• The move may reflect delayed or unreported information; a later re-check is warranted.
