He joins the UK largest independent aggregates producer as group chief executive officer, succeeding Simon Vivian, who moves to a non-executive role.
Peter Tom, Breedon’s executive chairman, said: “We’re fortunate to have persuaded one of the most successful and experienced executives in our industry to lead our business through the next phase of its growth.
“I’ve known Pat for more than 20 years and it’s rare to find someone with his combination of deep industry knowledge and outstanding leadership skills.
“It’s a measure of our achievement over the last five years that such a highly-respected figure within one of the world’s biggest building materials groups should decide to join the Breedon team.”
Ward is expected to join Breedon early next year once the terms of his departure from AI have been agreed and the required regulatory announcement will be made at that time.
He brings over 30 years’ experience in the aggregates and construction industries in the UK, US and Middle East.
Having held a variety of roles with ARC/Hanson, he joined AI in 1995.
He was appointed CEO of AI in April 2014, assuming responsibility for an international business with over 4,000 employees.
Ward said added: “It’s clear to me that Breedon has been able to flourish through a combination of the commitment and dedication of its employees and the strong leadership of Peter and Simon. This dedication is also apparent in the company’s visible commitment to Zero Harm across the entire business.
“I look forward to playing my part in the next leg of Breedon’s journey.”
Vivian said: “The company has doubled in size since Breedon’s formation in 2010 and we have a great team with a unique blend of experience and capability.
“While moving on is always difficult, I’m convinced that now is the right time for me to do so. I’ve known Pat for many years and am delighted that he is succeeding me at such an exciting time in Breedon’s development.”
