Knife River Corp

Knife River Corporation (referred to as we, our, us, the Company or Knife River) is an aggregates-based construction materials and contracting services provider in the United States. Our 1.3 billion tons of aggregate reserves provide the foundation for our vertically integrated business strategy, with approximately 35 percent of our aggregates in 2025 being used internally to support value-added downstream products (ready-mix concrete and asphalt) and contracting services (asphalt paving, heavy-civil construction, concrete construction, site development and grading services, and in some segments the manufacturing of prestressed concrete products). We are strategically focused on being the provider of choice in mid-size, higher-growth markets and are committed to our plan for continued growth and to delivering for our stakeholders—customers, communities, employees and stockholders—by executing on our Competitive EDGE initiatives and our four core values: People, Safety, Quality and the Environment.

Through our network of 208 active aggregate sites, 135 ready-mix plants, 55 asphalt plants and 9 liquid asphalt terminals, we supply construction materials and contracting services to customers across 14 states. Our construction materials are sold to public and private-sector customers, including federal, state and municipal governments, as well as industrial, commercial and residential developers and other private parties. Our contracting services are primarily provided to public-sector customers for the development and servicing of highways, local roads, bridges and other public-infrastructure projects.

We have broad access to high-quality aggregates in most of our markets, which forms the foundation of our vertically integrated business model. We share resources, including plants, equipment and people, across our various locations to maximize efficiency. We also transport our products by truck, rail and barge, depending on the particular market, to complete the vertical value chain. Our strategically located aggregate sites, ready-mix plants and asphalt plants, along with our fleet of ready-mix and dump trucks, enable us to better serve our customers. We believe our integrated and expansive business model is a strong competitive advantage that provides scale, efficiency and operational excellence for the benefit of customers, stockholders and the broader communities that we serve.
