New projects and new or expanded Master Services Agreements (MSAs) comprise approximately 81% of the award value, with the remaining 19% representing renewals of existing MSAs with tenured customers. The mix of work includes multi-discipline scopes of work in support of a hyperscale data center, the first project secured as a result of the recent JJ White acquisition. In addition, the Company received a major project award to complete the third phase of complex natural gas infrastructure upgrades for a long-standing client. Other awards include the rebuild of 23 miles of transmission line for a new customer and installation of approximately 14 miles of natural gas pipeline under MSA renewal.

"Our latest commercial awards are the result of intentional pursuit of profitable growth in strategic markets, specifically diversified across our core electric and gas capabilities, with attractive opportunities in data centers as well as multi-stage projects that have historically delivered double digit profit margins," said Centuri President and CEO Christian Brown. "In addition, we’re pleased to see immediate value resulting from our recent acquisition delivering increased scale to support the electric and industrial markets."

Today’s announced awards complement previous bookings, bringing the Company’s total commercial awards for year-to-date 2026 to approximately $2.6 billion.
