ATKINSREALIS ANNOUNCES CHANGES TO SENIOR LEADERSHIP TEAM

Atkinsrealis Group Inc. has made key changes to its senior leadership team to further strengthen our capability to deliver on the company's delivering excellence, driving growth strategy. These appointments ensure that Atkinsrealis has the senior leadership to meet the objectives and priorities the company has set for its business in the coming years.

New appointments

The following appointments, effective March 1, 2025, further strengthen the company's senior leadership team, bringing individuals with significant expertise and experience to deliver the company's growth and operating margin priorities in engineering services, while also continuing to strengthen the company's nuclear leadership team. This will enhance the company's project execution and delivery capability, as global demand for nuclear energy has fuelled the significant increase in the company's project backlog. All four leaders are highly skilled, and each will bring fresh perspectives and be pivotal in continuing to drive the company forward. These appointments are the result of strong succession plans built over time and show both the strength in depth and the deep operational experience Atkinsrealis has within the company.

Richard Robinson, currently president of United Kingdom and Ireland, will become president -- Asia, Middle East and Australia (AMEA), and oversee the company's expansion in AMEA, building on its long-standing local presence in rapidly growing markets through the delivery of major infrastructure, transportation and clean energy programs. Drawing on a wealth of international experience, including previously leading large engineering businesses in the Middle East, Mr. Robinson will focus on maximizing the growth potential across the region and will continue to oversee the company's expansion in the global defence market.

Chris Ball, currently chief operating officer of Atkinsrealis's nuclear business, joins the company's executive committee and will replace Mr. Robinson as president, United Kingdom and Ireland, and be responsible for the company's significant presence across the region, with over 12,000 employees providing end-to-end engineering, program management and advisory services.

Nigel White, currently chief risk officer, will become the chief operating officer for the nuclear sector. Mr. White brings over three decades of international experience delivering large complex projects, and his experience will be invaluable to ensuring the necessary project management, operational and risk processes are embedded in the nuclear sector, with a particular focus on the life extension and new build projects.

Joel Tache, currently senior vice-president, finance, commercial and risk for the nuclear sector, will replace Mr. White as chief risk officer and will also join the executive committee. Mr. Tache has significant experience in risk management at global organizations over many years, including in his previous role as vice-president, corporate risk management, at the company.

Ian L. Edwards, president and chief executive officer of Atkinsrealis, said: "These appointments highlight the strength and experience we have within Atkinsrealis. I am confident that their expertise, combined with their deep knowledge of our organization, our clients and the countries we operate in, will enhance our ability to drive growth, deliver excellence and manage risk across engineering services, nuclear and the wider organization. I am delighted to welcome Chris, Richard, Nigel and Joel into their new roles within the company, and work closely with them to deliver on our strategic agenda."

Office of the COO

Atkinsrealis is also announcing today that Philip Hoare will be stepping down as chief operating officer to pursue other professional opportunities. He will be staying in his role until the summer of 2025 allowing a suitable transition period to find a replacement for this role, and to continue to work on delivering the key priorities of driving growth and achieving consistent and sustainable margin performance improvement through the development, optimization and deployment of Atkinsrealis' global capabilities.

"I would like to express my heartfelt gratitude to Philip for his invaluable contributions to Atkinsrealis over many years, and to me personally. Under his leadership, he has established a robust framework for the COO's office, fostering a structured approach to delivering excellence and driving growth," said Ian L. Edwards, president and chief executive officer of Atkinsrealis.
