The Chief Executive of dairy company Ornua, John Jordan, is stepping down.
Mr Jordan is taking up a new role as Chief Operating Officer with a US-based private equity company.
He had led Ornua for five years.
Donal Buggy, the Chief Financial Officer of the organisation, has been appointed to lead the company as interim CEO during the search for a permanent replacement.
That process has got underway.
"It has been a huge honour for me to be the Chief Executive of Ornua, and to have spent three decades working in this business," said Mr Jordan.
"I am so proud of the positive impact that Ornua creates for its Co-Op shareholders and in turn for the 14,000 Irish dairy farming families that supply them and enable Ornua to create world-class premium products for our customers globally.
"I am confident that Ornua will go from strength to strength. We have great brands and a brilliant team."
Chairman of Ornua Co-operative, Aidan O'Driscoll, paid tribute to Mr Jordan's contribution.
"John Jordan has been an excellent Chief Executive for Ornua over the past five years, and prior to that he held several other key management roles," he said.
"John has given a huge part of his professional life to Ornua, as he joined us approximately 30 years ago. It has been a privilege to work with him, and on behalf of the Board, the Executive and the rest of the Ornua team, I want to thank John for all his efforts and wish him the very best for the future."
In April Ornua, which owns the hugely successful Kerrygold brand, said it had recorded record revenues of more than €3.4 billion last year, an increase of 36.7% on its 2021 performance.
Despite that Ornua saw its operating profit fall 17.2% to €127.2m.
