Knife River Corporation is a vertically integrated aggregates-based construction materials and contracting services provider operating across multiple U.S. states. The company extracts and processes aggregates (crushed stone, sand, and gravel), manufactures ready-mix concrete and asphalt, distributes liquid asphalt, and provides heavy-civil contracting and paving services through an integrated network of mines, processing plants, and logistical infrastructure. Revenue derives from both the sale of construction materials and contracting services, with the majority of customers being public-sector entities such as government agencies funding infrastructure and highway projects, while private-sector customers include residential, commercial, and industrial developers; the company generates revenue from aggregates, ready-mix concrete, asphalt, liquid asphalt, contracting services, and ancillary products.
