The Thai company is buying most of its stake from Graphite Capital, a private equity firm which invested £21m in Corbin & King in 2012 to fund expansion.
According to The Sunday Times, in May 2017 Graphite appointed PMB Capital to advise on the sale of its 45% stake in Corbin & King.
Corbin & King has since opened four more restaurants: Colbert, Brasserie Zédel, Fischer’s and Bellanger. In 2014, the group opened luxury Mayfair hotel The Beaumont, the revenue of which has grown steadily.
Revenues of the restaurant group have more than trebled and are now in excess of £45 million.
“Chris Corbin and Jeremy King have built a reputation as London’s most successful restaurateurs over the past 35 years,” Graphite senior partner Andy Gray said.
“We are pleased to have played an important part in the development of such an iconic business and are delighted that it has shown consistent growth during our investment period.”
