Knife River has a proven track record of acquisition and expansion within the construction materials industry. Our strategy is to acquire established businesses that have a proven history of performance, strong management, workplace safety and environmental compliance. In addition, we are seeking to grow our materials-based operations and to target opportunities in mid-sized markets that have above average growth potential.
