(Reuters) - Ramsay Health Care Ltd <RHC.AX>, Australia's biggest private hospital operator, said on Friday its French subsidiary had made an unsolicited takeover offer for Capio AB <CAPIO.ST>, valuing the Swedish healthcare company's equity at 661 million euros ($770.5 million).
Ramsay said unit Ramsay Générale de Santé <GDSF.PA> was offering 48.5 Swedish Kronas for each Capio share, representing a premium of 16 percent to its last close.
The acquisition is expected to be core earnings per share- accretive for Ramsay in two to three years, Ramsay said, adding that Ramsay Générale expected pre-tax synergies of about 20 million euros in the same period.
The offer document will be published by early-September.
Capio, which operates hospitals and clinics across Sweden, Norway, France, Germany and the United Kingdom, said last month that it was in talks on possible divestment of its non-nordic operations.
