John Magnier and family
Bloodstock, Investment
Rank 2017

Magnier, 69, owns and runs one of the world’s largest thoroughbred studs through his growing €98m Coolmore operations in Co Tipperary, Kentucky and Australia. He has used profits from this to acquire other assets, mainly held in offshore tax havens, which make them difficult to value. Much of his wealth derives from his role as a big player on the government and corporate bond markets. Among his other assets are 20% of the €654m Barchester Healthcare, one of the UK’s largest private residential care providers, and a 33% share of the Sandy Lane Hotel in Barbados. With the racehorse owner JP McManus and Aidan Brooks (both qv), he has, via Sloane Capital, a property portfolio worth more than £860m, with borrowings. It includes Unilever’s headquarters by the Thames in London, and Two Rodeo Drive, a  Beverly Hills shopping centre. In December, he made €175m profit on the €1bn sale of Vendôme Saint-Honoré, a block of buildings beside the Ritz in Paris, to Norway’s sovereign wealth fund. He has also been an investor in Manchester United and owns one of Europe’s most valuable private art collections with his wife Susan, daughter of the racehorse trainer the late Vincent O’Brien. Born in Fermoy, Co Cork, and educated at Glenstal Abbey, Magnier also has a home in Barbados, a beachfront house in Marbella and a lakeside mansion in Geneva. It was reported last month that his family had bought the €52m 4,000-acre Sutton Scotney estate in Hampshire.
