Centuri announces commercial awards in excess of $300M

New bid work and new or expanded Master Services Agreements (MSAs) comprise approximately 87% of the award value, with the remaining 13% representing renewals of existing MSAs with tenured customers. The mix of work includes MSA renewals for natural gas distribution infrastructure upgrades that include expanded scopes of work and crew growth with long-standing utility customers; a gas facility upgrade project; assembly and installation of key components benefiting a midstream energy infrastructure company; engineering and construction services in support of a transmission infrastructure project; and the procurement and construction of electrical infrastructure for the first phase of a wind farm project in Canada.

The company remains in active negotiations on approximately $400 million of further contract awards, which include data center-related scopes of work. The most recent awards, along with a robust opportunity pipeline, indicate that Centuri now expects a book-to-bill of approximately 1.2x for the year.

"We continue to experience strong commercial momentum, reflecting the trust we have earned from our customers and the reputation we have built in our core end markets," said Centuri President and CEO Christian Brown. "We're especially pleased to receive a new award through our recent Canadian acquisition, proving the combined strength of our joint capabilities to earn new opportunities in an expanding Canadian market. In general, the demand for new and upgraded infrastructure is unprecedented, and we are well positioned to deliver the value-added solutions our customers require while simultaneously creating long-term shareholder value through our Vision One Centuri."

Today's announced awards complement previous bookings, bringing the company's total commercial awards for year-to-date 2026 to approximately $1.7 billion.
