Our Companies

Summit Materials was formed in 2009 with a bold vision to form a new kind of heavy-side, building materials company: one that brings together successful companies to create an interdependent and yet well supported whole. Summit brings value to its family of companies by maintaining an entrepreneurial spirit and local presence, while providing access to resources and shared best practices. Today, Summit has 12 platform companies operating in 23 states and British Columbia, Canada. These companies provide aggregates, cement, ready-mix, asphalt, and construction services to meet residential, nonresidential, and public demand. Under CEO Anne Noonan, Summit continues to drive growth and efficiencies across its operating companies to deliver shareholder value.
