MADRID, 24 Ago. (EUROPA PRESS) -

Private equity firm Roark Capital, owner of Dunkin and Arby's, has completed the acquisition of Subway, the fast-food restaurant chain specializing in sandwiches, the company announced Thursday.

Although the economic details of the transaction have not been revealed, the newspaper 'The Wall Street Journal' pointed out this week that it could be around 9,600 million dollars (8,825 million euros).

"This transaction reflects Subway's long-term growth potential and the substantial value of our brand and our franchisees around the world," said John Chidsey, Subway's CEO, who said the chain has a bright future with Roark.

Since its founding in 1965, Subway had been owned by its two founding families and is now the eighth largest restaurant chain in the United States.
