Summit Materials

Razorback is an aggregates-based business with the largest ready-mixed concrete operations in central and northeastern Arkansas, representing a new regional market for Summit,” added Hill. “Importantly, given Razorback’s proximity to Summit’s existing cement distribution terminal in Memphis, Tennessee, the acquisition is consistent with our long-term strategy to develop materials-based positions in select markets along the Mississippi River served by our cement business. We believe the Arkansas market is poised for higher construction activity levels over the longer term, driven by positive employment and population trends and increased public infrastructure spending.”
