Summit Materials (NYSE:SUM) is a diversified construction materials company engaged in the production and distribution of aggregates, cement, ready‐mix concrete, asphalt and complementary products and services. The company’s operations are organized to serve a broad range of infrastructure, commercial and residential construction markets, working with contractors, developers and public‐sector clients to deliver essential materials for road building, urban development and industrial projects.
Founded in 2014 through a combination of Summit Materials North America Operations and Rocky Mountain Materials via a special‐purpose acquisition, Summit Materials is headquartered in Denver, Colorado. Under the leadership of President and Chief Executive Officer Thomas Hill, the company has pursued an acquisition‐led growth strategy, integrating local and regional businesses to expand its footprint and product offerings while maintaining a decentralized operating model.
Summit Materials operates across 22 states in the United States and in select Canadian provinces, organized into regional segments that include the Mountain West, Southwest, Northeast and Southeast markets. This geographic diversification enables the company to balance seasonal demand fluctuations, access varied resource deposits and maintain stable supply chains for customers spanning urban population centers and remote infrastructure sites.
With a focus on operational safety, environmental stewardship and customer service, Summit Materials invests in modern production facilities, fleet management technologies and training programs. Its vertically integrated platform—from quarrying and cement manufacturing to on‐site concrete and asphalt placement—allows for efficient coordination of logistics, quality control and cost management, positioning the company as a reliable partner in North America’s construction industry.
