Qualys is trading at $99.71, down 45.61%, with no reliable company-specific announcement, earnings release, or major filing identified to explain the after-hours decline.
- Qualys’ next expected earnings report is November 3, 2026, making an earnings reaction unlikely.
- A reported CEO stock sale occurred September 14, 2026, under a Rule 10b5-1 plan, but it predates this move and does not establish causation. The magnitude appears isolated rather than explained by the provided broader market moves.
