CalPortland will acquire Vulcan Materials’ ready mixed concrete business assets in California, providing stable demands for the cement produced at its plants, as well as imported cement and supplementary cementitious materials.
The transaction encompasses 41 concrete plants and two cementitious material terminals, affording CalPortland an unrivaled position in ready mixed capacity along coastal California. Overall, the producer stands to close 2025 with more than 60 Golden State ready mixed plants, many strategic to sister Redding (north), Mojave (central-south) and Oro Grande (south) cement operations.

“Through this transaction, we expect to achieve steady growth in both sales and profits by strengthening the revenue base of our U.S. ready-mix business, enhancing our supply chain, including our group’s trading network, and expanding low-carbon supplementary cementitious materials initiatives,” said CalPortland parent company Taiheiyo Cement.
The acquisition is subject to clearance from relevant authorities and other closing conditions, and is expected to be finalized by December.
