Martin Marietta Materials, Inc. is a prominent building materials company primarily focused on the supply of aggregates such as crushed stone, sand, and gravel throughout the United States and beyond. With around 360 operational quarries, mines, and distribution yards spread across 28 states, Canada, and the Bahamas, aggregates represent 68% of the company's gross profit. In addition to aggregates, Martin Marietta also provides cement and related downstream products, including ready-mixed concrete and asphalt, targeted mainly for infrastructure, nonresidential, and residential construction markets. Their operations are sensitive to economic conditions and public-sector funding, affecting their profitability significantly.
The company operates through two primary segments: the Building Materials segment, which is geographically divided into East Group and West Group, and a distinct Magnesia Specialties segment producing magnesia-based chemicals and dolomitic lime. Recent strategic acquisitions, such as Albert Frei & Sons, enhance their operational footprint in high-growth regions. By optimizing their portfolio through divestitures of non-core assets, the company aims to focus on pure-play aggregates growth, making it well-positioned to respond to the increasing demand for construction materials in a curve-sensitive and competitive market landscape.
