FORMER Alinta Ltd chairman John Poynton believes an opportunity to keep the business Western Australian-based has been lost, with the directors’ decision to accept a $15 per share bid from Babcock & Brown Ltd. Mr Poynton was part of the management buyout team which was backed by Macquarie Bank, which was the losing bidder despite offering a higher price at $15.45 per share, an 11th-hour offer which sought to trump the $7.4 billion Babcock & Brown deal.
