ATKINSREALIS APPOINTS BYRON BRIGHT AS PRESIDENT, U.S.

Atkinsrealis Group Inc. has appointed Byron Bright as president, United States., as part of a planned transition, succeeding Steve Morriss effective July 1, 2026. In this role, Mr. Bright will build on the strong foundation established by Mr. Morriss, who prior to his retirement will remain with Atkinsrealis, and continue to oversee the global minerals and metals business, and lead the company's growth market with the hyperscalers until the end of the year.

This succession comes as Atkinsrealis continues to strengthen its position in the U.S., rising from 20th to 16th in the ENR 2026 Top 20 Design Firms ranking and delivering a strong first quarter marked by record backlog.

"Byron is a proven leader with a strong track record of delivering results in complex, high-stakes environments," said Ian L. Edwards, president and chief executive officer of Atkinsrealis. "His operational experience, growth-centred mindset and values make him the right leader to accelerate the next phase of development in this critical region. I also want to thank Steve Morriss for strengthening our U.S. business and positioning it for continued success."

"Atkinsrealis has built a strong presence across the U.S., underpinned by deep technical expertise and trusted client relationships," said Mr. Bright. "I was particularly drawn to the organization's shared values and its culture of caring for people, which remain central to its growth strategy and set it apart in the market. I'm energized by the opportunity ahead and look forward to working with the team to build on this foundation, expand our capabilities and deliver exceptional outcomes for our clients."

Mr. Bright brings more than 25 years of experience across engineering, technical services, program management and government services. Prior to joining Atkinsrealis, he served in multiple executive leadership positions at KBR Inc., including president of KBR Government Solutions and most recently chief operating officer. During his tenure, he helped scale KBR's government business through disciplined organic growth and strategic acquisitions, an experience directly aligned with Atkinsrealis's priorities.
