Case Description

USDOJ and State of Texas challenged the acquisition of Texas Industries by Martin Marietta Materials on the grounds that the proposed merger would have likely resulted in increased prices for customers handling Texas Department of Transportation projects in parts of the Dallas metropolitan area. The
Texas Department of Transportation sets specifications for the type of aggregate approved for use in those projects. In Dallas County and parts of the surrounding area,
Martin Marietta and Texas Industries are two of the only three suppliers of Texas Department of Transportation-approved aggregate. Under the terms of the proposed consent decree, Martin Marietta must divest its North Troy aggregate quarry in Mill Creek, Oklahoma, its rail yard in Dallas, and its rail yard in Frisco, Texas. All of these assets
predominantly serve parts of the Dallas metropolitan area. Under the proposed settlement, USDOJ Antitrust Division, after consultation with Texas, must approve the buyer of the divested assets.
