Pulse Analysis

After 18 years with Mace, Jason Millett announced he will leave his post as group chief executive at the end of December 2026. His exit is timed to coincide with the finalisation of the carve‑out of Mace Consult, which now operates as an independent programme‑management business. Millett, who joined the firm during the London 2012 Olympic Village build and later helped lead the 2013 management buy‑out, has overseen both the Consult and Construct divisions through a period of rapid growth and diversification. The move also gives the board time to identify a successor who can build on the demerger’s momentum.

The separation leaves Mace Construct as a leaner, single‑track construction house, positioning it to compete more aggressively for large‑scale infrastructure and commercial contracts in the UK and abroad. With a clearer balance sheet and no cross‑selling obligations to the consulting arm, the firm can allocate capital to technology‑driven delivery methods and sustainability initiatives that are reshaping the sector. Analysts expect the streamlined model to improve margins, especially as the UK government ramps up spending on transport and housing projects. Early signs already show a modest uptick in order intake, suggesting the market is responding positively to the clearer focus.

Millett’s departure also opens the boardroom to a new generation of leadership, with executive chair Mark Reynolds slated to take a more hands‑on role in shaping Mace’s post‑carve‑out strategy. While the outgoing CEO has hinted at staying active in the broader built environment, his next venture could inject fresh talent into rival firms or advisory platforms. For investors, the transition underscores a period of strategic realignment, and the market will be watching how quickly Mace can translate its simplified structure into earnings growth. Overall, the leadership shift is likely to be a catalyst for renewed investor confidence as Mace pursues its growth agenda.
