Currently, Rossmann holds 60% of the company, because in the 80s, he sold 40% of the shares to Hanover Finanz, which later (in 2004) sold them to Hutchison Whampoa owned by Hong Kong billionaire Li Ka-Shing. His sons, Raoul and Daniel, also work for the family business. In addition to his drugstore chain, Rossmann owns 25% of Deutsche Beteiligungs AG (known as DBAG), a German private equity firm, and his stake worth approximately $95 million. Furthermore, he founded a charitable foundation in 1991 that is focused on family planning.
