Claude Guillemot's Death Tests Ubisoft's Family Control Structure

Claude Guillemot, co-founder and chairman of the family holding company controlling Ubisoft, died in a plane crash near La Baule on June 20. The five Guillemot brothers founded the video game publisher in 1986 and retain operating control alongside their majority stake—a governance model rare among public game companies. The family now confronts succession planning as Ubisoft faces sustained sales pressure and ongoing strategic review.
