Centuri Holdings Announces Appointment of Christian (“Chris”)

Brown as President and Chief Executive Officer

Mr. Brown Brings Deep Experience in the Energy and Infrastructure Sectors

Experienced CEO with Proven Track Record of Financial Performance through Organic Growth, M&A and Diligent Capital Allocation

PHOENIX, November 5, 2024 — Centuri Holdings, Inc. (NYSE: CTRI) (“Centuri” or the “Company”), a leading, pure-play North American utility infrastructure services company, today announced its Board of Directors has appointed Christian (“Chris”) Brown as President and Chief Executive Officer of Centuri, effective December 3, 2024. Mr. Brown will be appointed to the Centuri Board at that time. Mr. Brown succeeds Paul Caudill, who was appointed Interim President and CEO effective July 31, 2024.

Brown brings expertise in leading large, complex organizations through periods of significant evolution and growth in the energy and industrial sectors, including engineering and construction (E&C), during a career that has spanned more than three decades. Most recently, he served as CEO of EnerMech, a privately held global energy and infrastructure services company, where he developed and implemented their leading change strategy, which resulted in strong revenue growth and a differentiated service offering. Prior to this, he served as CEO of Kentz Engineers & Constructors, a FTSE 250-listed E&C business across energy, infrastructure, and utility sectors, where he was instrumental in driving a nearly sixfold increase in revenue over five years, and successfully led the company through its sale to SNC-Lavalin (now known as AtkinsRéalis), a TSX-listed E&C company. Chris has resided in Houston with his family for over 20 years.

“Throughout his impressive career, Chris has consistently demonstrated his strategic vision, operational expertise and ability to drive success and increased stakeholder value,” said Karen Haller, Chair of Centuri’s Board of Directors. “His background and experience in engineering have fostered a hands-on operational approach that has resulted in a strong technical and practical understanding of the utility sector. Across roles, his commercial acumen has led to significant growth, both organically and through tuck-in acquisitions. We look forward to benefitting from Chris’ global experience leading both publicly traded and privately held companies within the industry, and his existing relationships with some of Centuri’s customers. We are confident Chris is the ideal leader to advance our strategic initiatives and drive growth at Centuri as a world-class utility infrastructure services platform.”

“I am excited to join the team during a truly transformative period for the industry,” said Chris Brown. “Centuri stands as a leader in the utility infrastructure sector with a strong track record of safely delivering solutions across customers’ value chains. As utility companies continue to look for solutions to replace aging infrastructure and emergent technologies and clean energy initiatives grow, Centuri is well positioned to serve as a critical partner. I look forward to working with the leadership team and the Board of Directors to further identify and execute key strategic initiatives, as we capitalize on these opportunities and enhance efficiencies across the Company. As CEO, I am eager to leverage my extensive industry experience and broad-based network to support Centuri’s expanding customer base and guide the Company’s future growth trajectory.”

Ms. Haller added, “On behalf of the Board, I also want to thank Paul Caudill for his leadership and contributions as Interim CEO over the past few months. Paul provided important continuity and continued to lead strategic initiatives during a critical period for the organization. I am grateful for his leadership and his willingness to support Chris’s transition.”
