Ten CEO exits landed in 2026, and they cluster in five months — none documented in January, May, or August

A live-web, source-documented roster of chief executives who actually ceased serving between January 1 and August 27, 2026 — worldwide, one row per CEO and organization. This is 10 source-documented departures found, not a census: announced-but-future departures and roles below CEO are excluded, and a blank value means the available source did not establish that detail.

Method: live-web scan performed 2026-08-27 covering worldwide organizations; 10 rows, one per CEO and organization, deduplicated. A row counts only a departure that actually took effect between 2026-01-01 and 2026-08-27; announced future exits and roles below CEO were cut. Effective date is shown where the source stated one, otherwise the departure month. A blank cell means the source did not establish that detail. This roster documents what was found, not all real-world departures.
