ATKINSREALIS STRENGTHENS EXECUTIVE LEADERSHIP TO ACCELERATE GROWTH AND OPERATIONAL EXCELLENCE

Atkinsrealis Group Inc. has made key leadership appointments to its executive committee. These changes are designed to reinforce the company's ability to deliver on its "delivering excellence, driving growth" strategy by enhancing operational execution, strategic alignment and global growth capabilities.

Executive appointments

Effective Aug. 23, 2025, Louis G. Veronneau will rejoin Atkinsrealis as chief operating officer, based in Montreal. In this role, he will lead the company's global operations, including transformation, strategy, technology, M&A (merger and acquisition), deliver work and global communications. As the company continues to expand the deployment of capital into acquisitions to support its strategy, the M&A team will move to also report to Mr. Veronneau so that strategy, acquisitions and transformation can be most effectively aligned to create value. The COO role is central to driving operational excellence and ensuring that enterprise-wide initiatives are tightly aligned with the company's financial and strategic goals.

Mr. Veronneau will be instrumental in advancing the company's margin improvement agenda by embedding disciplined execution, accelerating transformation and optimizing delivery models across the business. He brings over 30 years of leadership experience across investment management, infrastructure, industrials and legal sectors. He most recently served as senior managing director and global head of real estate investments at PSP Investments, where he oversaw a global portfolio valued at approximately $38-billion. He previously served as executive vice-president and chief transformation officer at Atkinsrealis, where he played a pivotal role in launching the company's transformation strategy. His earlier career includes senior roles at Bombardier, TD Securities and Abitibi-Consolidated.

On Sept. 1, 2025, Kate Kenny will join the company as chief growth officer, based in London. She will lead the company's global growth agenda, including oversight of the global technology centre (GTC), win work, marketing, government relations and global capabilities. The CGO role is designed to drive sustainable, profitable growth by strengthening client engagement, expanding market presence and deploying differentiated, end-to-end capabilities that support delivery across the full project life cycle.

Ms. Kenny's appointment reflects Atkinsrealis's commitment to building on its growth momentum and unlocking new opportunities through innovation, strategic positioning and client-centric solutions. Ms. Kenny brings over two decades of experience in infrastructure, consulting and urban development. She spent the majority of her career at Jacobs, where she held a variety of P&L and growth leadership roles across the United Kingdom and Europe. Most recently, she served as executive vice-president and general manager for Jacobs's approximately $2-billion European business, overseeing more than 7,500 professionals across strategic consulting, transportation, water and environment, the built environment, and major programs.

"These appointments reflect our ability to attract high-calibre individuals who bring deep industry expertise and proven leadership," said Ian L. Edwards, president and chief executive officer of Atkinsrealis. "Louis will build on the strong foundation of our transformation journey to drive the next phase of operational excellence and margin improvement. Kate will lead our global growth agenda, strengthening client engagement and expanding our market presence. Together with our broader leadership team, they will help accelerate our strategy and deliver long-term value for our clients and shareholders."

Transition of the COO office

These changes follow the planned departure of Philip Hoare, who will step down as chief operating officer in summer 2025 to pursue new professional opportunities. Mr. Hoare has played a critical role in shaping the COO office and advancing the company's operational excellence agenda. "I want to thank Philip for his outstanding contributions to Atkinsrealis and for laying the foundation for a strong and structured COO office," added Mr. Edwards. "His leadership has been instrumental in driving growth and performance across the organization."
