JSM Group is pleased to announce the appointment of a new Chief Executive Officer, marking a significant milestone in the company’s journey. The incoming CEO, Michael Booth, will lead the business alongside Chief Operating Officer and Co-founder John Scanlon and Chairman John Leahy, as the company continues to build on its strong foundation and ambitious growth strategy.
Michael Booth served as JSM Group’s Chief Financial Officer since February 2025, playing a key role in shaping the company’s financial strategy and supporting its expansion into new markets. With a deep understanding of the infrastructure sector and a proven track record of leadership, Michael steps into the CEO role with the support of shareholders, TowerBrook Capital Partners, and Chairman, John Leahy, with immediate effect, reflecting JSM Group’s commitment to continuity and long-term growth.
Commenting on his appointment, Michael Booth said:
I’m honoured to take on the role of Chief Executive Officer at such a pivotal moment in JSM Group’s journey. Having worked closely with Stuart, John, and the wider leadership team, I’ve seen first-hand the strength of our people and the scale of opportunity ahead. As CEO, my focus will be on integrating our capabilities, communicating with clarity, continually evolving to meet industry demands, solving complex challenges, and driving meaningful outcomes for our clients and communities. These values are at the heart of JSM Group, and I’m excited to lead with them as our guide.
Stuart Wiltshire, who founded JSM Group in 1998 with brothers John and Mark Scanlon, is stepping-down due to ill-health but will continue to support the business with strategic oversight and guidance. Under their leadership, JSM Group has grown into a leading infrastructure services provider, with Mark Scanlon playing a pivotal role in the early success of the business before his departure in 2019 to pursue new ventures.
John Scanlon, COO and Co-founder, will work closely with the new CEO to ensure a smooth transition and continued operational excellence. Together, they will focus on strengthening JSM Group’s position both in the UK and overseas, with a particular emphasis on supporting the growth of data centre infrastructure and renewable energy projects, two key pillars of the company’s future-facing strategy.
Commenting on the transition, Stuart Wiltshire said:
It has been an incredible journey building JSM Group with John and Mark. I’m proud of what we’ve achieved and excited to support the next chapter of growth from a distance. With Michael and John at the helm, I’m confident the business is in excellent hands.
The appointment of the new CEO reflects JSM Group’s commitment to evolving its leadership to meet the demands of clients and a dynamic industry while staying true to its founding values.
