MARTIN MARIETTA MATERIALS INC
martinmarietta.comMartin Marietta Materials (NYSE: MLM) is a natural resource-based building materials company that quarries, produces, and sells aggregates and related construction materials across the United States. Revenue is transactional, generated by selling crushed stone, sand, and gravel to contractors, governments, and builders at per-ton prices. The company operates through two reportable segments: Building Materials and Magnesia Specialties. In FY2024, Martin Marietta completed the acquisition of 20 active aggregates operations from Blue Water Industries LLC affiliates in Alabama, South Carolina, South Florida, Tennessee, and Virginia for $2.05 billion, while simultaneously divesting its South Texas cement business and related ready mixed concrete operations to CRH Americas Materials for $2.1 billion in cash, realizing a pretax gain of $1.3 billion. The company also acquired Albert Frei & Sons, Inc. in January 2024, adding more than 60 years of hard rock reserves in the Denver metropolitan area. These moves reflect a deliberate portfolio shift toward aggregates-focused operations.
