Mace has unveiled a series of changes to its executive leadership team.
In January next year, the group will split the combined group chair and chief executive role, with Mark Reynolds becoming executive chair of the group and Jason Millett – currently group deputy chief executive – taking the role of group chief executive.
Over the next six months, Reynolds and Millett will manage the transition of leadership across the group establishing new governance structures and enabling the succession process in their teams.
As part of the new business structure, Gareth Lewis – currently CEO of Mace Construct – will stand down in July this year after a 27-year career with the group, and Davendra Dabasia will become CEO of Mace Consult with Andrew Jackson becoming CEO of Mace Construct.
Mace will also be adopting the UK Corporate Governance Code and will appoint four non-executive directors in January 2025, establishing a new group board. The non-executive directors are: Dame Alison Nimmo DBE, previously CEO of the Crown Estate, who will serve as senior independent director; Nina Bjornstad; Eric Hageman; and John Coghlan, currently a director of Landmark.
The new non-executive directors will join Reynolds, Millett and Mace Group’s chief financial officer David Allen on the new group board.
Reynolds said: “Mace is now a truly global force; and our success over the past few years securing some of the world’s largest programmes reflects that. With scale comes responsibility, and we must ensure we are governed effectively. These long-planned succession changes are a part of that process. After 12 years leading Mace, and a decade of working alongside Jason, I couldn’t be more pleased to see him step into the group chief executive role. He, Davendra and Andrew will shape the next decade of Mace’s journey, and I have absolute confidence that they will continue our phenomenal growth.
“I am also very proud that Alison, Eric, John and Nina have agreed to join the new group board as non-executive directors. Over the last 12 months on Mace’s advisory board they have proven an invaluable source of challenge and insight; and I am looking forward to working together more closely as we begin the next phase of our exciting journey.”
Millett added: “I am honoured to have been named the next chief executive of Mace – it’s an exciting opportunity to build on everything we have achieved as a company over the last three decades.
“Our combined consultancy and construction expertise is a unique combination that enables us to deliver some of the most complex and challenging projects around the world on behalf of our clients; and I can’t wait to work with the new board, the group executive committee and all of the brilliant teams across Mace as we bring together our vision for the next 10 years of success.”
