A consortium led by KKR & Co. offered to buy Ramsay Health Care for A$20.1 billion ($15 billion), chasing a network of private hospitals across Australia and Europe treating millions of patients a year. Investors led by the US private equity firm bid A$88 for each Ramsay share, the Sydney-based company said on Wednesday. That’s about a 37 per cent premium to Ramsay shares’s closing price of A$64.39 Tuesday.
