After four years on the board, Ian Coull has left his role as non-executive chairman of Galliford Try with immediate effect.
Galliford Try said Mr Coull will step down “due to other business and personal commitments”.
The contractor said that following a board review, current chief executive Greg Fitzgerald will assume the role of executive chairman up until December 2015 at the latest.
Mr Fitzgerald announced last month he would quit the company after 33 years by the end of 2015.
He is assisting the firm’s nominations committee in the recruitment of a new chief executive.
Peter Rogers, non-executive director and senior independent director, will assume the role of interim deputy chairman and will support Greg in his role.
Mr Coull said: “As a result of my growing business and personal commitments I have decided to step down as chairman after just under four very enjoyable years at Galliford Try. I leave the business in very capable hands, and in an excellent financial position with a clear growth strategy.”
Peter Rogers, senior independent director, said: “The board is immensely grateful to Ian for his significant contribution to Galliford Try during an exciting period of growth for the group. Whilst we are sad to see Ian leave we completely understand his reasons for going.”
