Knife River Corp

Knife River Corporation is a provider of construction materials and contracting services in the United States, with a foundation in aggregates. The company holds 1.3 billion tons of aggregate reserves, which support its vertically integrated business strategy. Approximately 35 percent of its aggregates in 2025 are used internally to produce value-added downstream products such as ready-mix concrete and asphalt. Knife River also provides contracting services including asphalt paving, heavy-civil construction, concrete construction, site development and grading services, and in some segments, the manufacturing of prestressed concrete products. The company operates a network of 208 active aggregate sites, 135 ready-mix plants, 55 asphalt plants, and 9 liquid asphalt terminals. Through this network, Knife River supplies construction materials and contracting services to customers across 14 states. Its construction materials are sold to both public and private-sector customers, including federal, state, and municipal governments, as well as industrial, commercial, and residential developers and other private parties. Contracting services are primarily provided to public-sector customers for projects such as highways, local roads, bridges, and other public-infrastructure developments. The company's business model emphasizes broad access to high-quality aggregates in most of its markets and utilizes shared resources across locations to maximize efficiency. Products are transported by truck, rail, and barge to complete the vertical value chain.
