Buildings materials group, CRH, has announced that its Group Finance Director, Senan Murphy is to retire next year.
Mr Murphy has been in the role for five years and is to remain in his role while the board finds a successor, a process which has begun.
He will also ensure a smooth transition once a replacement is found, the company told investors.
"As Group Finance Director, Senan's experience and insights have been invaluable, as CRH navigated a period of significant change and development following major acquisition and restructuring activity," said Group Chief Executive Albert Manifold.
"We thank Senan for his significant contributions to the Group over the last five years, we welcome his commitment to ensuring an orderly transition to his successor and we look forward to wishing him well in his future endeavours, in due course."
Mr Murphy will remain as an adviser to the company after that transition.
"With an extensive finance function across CRH's three divisions, an internal candidate seems likely - albeit an external candidate cannot be ruled out," predicted Robert Gardiner, research analyst at Davy.
