The three private equity owners of Burger King have made $715m (€550m) in the past 12 months thanks to the share price performance of the US fast-food chain since it went public.

Texas Pacific Group, Bain Capital Partners and the private equity arm of Goldman Sachs bought Burger King in 2002 and floated it last May through Citigroup, JP Morgan, Morgan Stanley and Goldman Sachs. Last week, the sponsors filed to sell a $420m stake in a secondary offering.
