Case Description

USDOJ and plaintiff state challenged acquisition by British aggregate company of a local aggregate company with concrete plants serving eastern Massachusetts and New Hampshirealleging that the acquisition would reduce the number of ready-mix concrete suppliers able to service large construction projects in northern metropolitan Boston from three to two. In northern metropolitan Boston, Aggregate Industries and Wakefield often were each other’s most significant competitor. Aggregate Industries was required to divest the Wakefield facility to a third-party buyer. The state entered into an Assurance of Discontinuance with Aggregate Industries requiring it to relinquish a lease on another concrete plant in central Massachusetts.
