LOS ANGELES--(BUSINESS WIRE)--Dec 29, 2025--

Tutor Perini Corporation (NYSE: TPC) (the “Company”), a leading civil, building and specialty construction company, announced today that it has been awarded a change order valued at approximately $53 million for the City Center Guideway and Stations Project in Honolulu, HI. This change order is significant because it enables Tutor Perini to design the segment of the rail that will extend the current terminus and connect Kaka’ako to Ala Moana, including the addition of two stations along the alignment. Should the Honolulu Authority for Rapid Transportation secure additional funding and elect to extend the construction of the project towards Ala Moana, the Company’s total contract value for this project could increase substantially.
