Origin’s largest shareholder, A$300 billion ($198.36 billion) pension fund AustralianSuper, has said it would reject the A$9.39 per share offer. "If the Brookfield consortium comes back with a hostile off-market offer, there could be upside to the share price." "We will do this work before considering whether to continue pursuing a proposal to acquire Origin Energy or the Origin Energy Markets business," he said. The company's board last week rejected a revised back-up bid from the Brookfield consortium that the energy firm said was too complex and highly conditional.
