Talks had been ongoing for months regarding the spin-off with the purpose to grow the business, by providing flexibility to expand milk process capacity following the abolition of EU milk quotas in 2015.
‘Months of debate’
John Moloney, group managing director of Glanbia, said: "After a number of months of constructive and informative debate, we greatly welcome the strong endorsement by Society members of the Joint Venture proposal.
“While still subject to Glanbia plc shareholder approval, the approval by Society members represents a significant and penultimate step towards the completion of the Joint Venture. The Joint Venture presents substantial strategic opportunity for both Glanbia and the Society.
“From a Society perspective, it creates a strong platform from which to grow milk volumes and capture the benefits arising from increased milk production and processing post the abolition of milk quotas in 2015.
“For Glanbia plc, the Joint Venture enables it to continue its successful international growth strategy and maximise value for all shareholders. We now look forward to a successful vote by Glanbia plc shareholders on the Joint Venture proposal on 20 November".
