Audio By Carbonatix

BISMARCK, N.D.--(BUSINESS WIRE)--Dec 15, 2025--

Knife River Corporation (NYSE: KNF) announced today that it has acquired the assets of Texcrete Operations LLC and TexAgg LLC (collectively “Texcrete”), supporting the company’s growth efforts in the Texas Triangle.

Based in the Bryan/College Station market, Texcrete has six ready-mix plants and 85 ready-mix trucks serving Brazos and Montgomery counties. College Station is home to Texas A&M University and Montgomery County is one of the fastest-growing counties in the nation. Texcrete also operates a sand and gravel site that adds 20-plus years of aggregate reserves in the local market, at current production volumes.

“This acquisition fits our strategy of focusing on materials-based, vertically integrated operations in mid-size, high-growth markets,” said Brian Gray, Knife River President and CEO. “We expect the ready-mix plants will pull through aggregates from our existing Knife River operations, in addition to leveraging Texcrete’s own supply. We’re excited about the growth potential in Texas, and we further expect the addition of Texcrete will help balance the seasonality in our northern markets.”

Texcrete has approximately 100 employees, who have joined Knife River’s Texas team.
