Directorate Update

Further to the announcement on 15 May 2025, the Board of Keller Group plc ('Keller' or the 'Group') announces, with sincere regret, that Michael Speakman, Chief Executive Officer ('CEO'), has given notice that he will step down as CEO and as a director of Keller with effect from 18 August 2025 in order to continue with his necessary medical treatment.

The Board fully respects and supports Michael's decision to step down and extend their immense gratitude to him for his leadership, dedication, and significant contributions to the Group over his tenure. Michael will remain employed by Keller on an advisory basis.

Following a comprehensive search process, the Board is pleased to announce the appointment of James Wroath as CEO, effective 18 August 2025. James brings a wealth of relevant experience to the role, having most recently served as CEO of Wincanton plc. The Board is confident that he will provide strong leadership and strategic direction as the Group continues to deliver its successful growth strategy.

Carl-Peter Forster, Chair of Keller, said:

"On behalf of the Board and the Keller team, I would like to thank Michael for his outstanding leadership and immense contribution to the business since he joined the Group in 2018, initially as CFO, then from 2019 as CEO. During this time he has led the Group through a period of significant growth and development; rationalising the portfolio and improving the project execution across the business, resulting in a substantial uplift in the Group's performance and the delivery of improved returns. Michael steps down with the Group in a strong financial and operational position to continue to pursue its growth opportunities ahead. We wish Michael our very best as he continues his medical treatment."

"We are delighted to announce James as our incoming CEO. He brings the right blend of experience, vision and leadership to take the Group forward, most recently in his role as CEO at Wincanton plc and from his previous senior roles at two major businesses in the US, LSG Group and Kuehne + Nagel Inc. James is a proven FTSE CEO and successfully led Wincanton plc through a period of cultural and operational transformation, leading to the recent sale to GXO Logistics. He brings a strong track record of leading improved performance in geographically dispersed contracting businesses. I look forward to welcoming James to the Board".
