Gartner is trading 21.04% down now in after-hours trading at $141.79, after closing at $179.58 on August 12, 2026, with no clear company-specific catalyst identified.
- Searches found no company-specific announcement, earnings update, or analyst action dated August 12 explaining the decline.
- Gartner’s August 4 earnings beat and raised outlook previously triggered a sharp rally.
- Profit-taking is plausible, but that earlier catalyst does not clearly explain this late-session move.
