Johann Rupert is chairman of Swiss luxury goods firm Compagnie Financiere Richemont. Best known for the brands Cartier and Montblanc, the company was formed in 1998 by spinning off international assets owned by Rembrandt Group Limited (now Remgro Limited), a South African company his father Anton founded in the 1940s as a tobacco manufacturer. Rupert owns a 7% stake in diversified investment firm Remgro, which he chairs, as well as 25% of Reinet, an investment holding company based in Luxembourg that has a stake in British American Tobacco. He also owns part of the Saracens English rugby team and Anthonij Rupert Wines, named after his deceased brother. In recent years, Rupert has been a vocal opponent of plans to allow fracking in the Karoo, a region of South Africa where he owns land. Rupert says his biggest regret was not not buying half of Gucci when he had the opportunity to do so for just $175 million.
