KEY POINTS:
Sigma Pharmaceuticals is in talks with private equity investors over a possible joint counter-offer for medical centre and drugs group Symbion Health.
Australia's second biggest private hospital operator, Healthscope, made a A$2.9 billion ($3.3 billion) cash-and-scrip takeover offer for Symbion Health last month, a bid that has received the unanimous support of Symbion's directors. But Sigma said yesterday it was looking into making a rival bid for Symbion.
