Updated before January 2025

Company Overview

Martin Marietta Materials, Inc. (MLM) is a leading supplier of building materials, primarily serving the construction and infrastructure sectors. Founded in 1993 as a spin-off from Martin Marietta Corporation, the company has grown to become one of the largest producers of aggregates in the United States. Headquartered in Raleigh, North Carolina, MLM operates across more than 26 states, Canada, and the Bahamas. The company is led by C. Howard Nye, who serves as Chairman, President, and Chief Executive Officer. Under Nye’s leadership, MLM has focused on strategic acquisitions, operational efficiency, and sustainability initiatives to maintain its competitive edge in the market.

Core Business Segments

Martin Marietta Materials operates through three primary business segments:

1. Aggregates

The aggregates segment is the cornerstone of MLM’s operations. It includes the production and distribution of crushed stone, sand, and gravel, which are essential components for construction projects. These materials are used in infrastructure development, commercial construction, and residential projects. Key products include:

  • Crushed stone for road construction and maintenance.
  • Sand and gravel for concrete production.
  • Specialty aggregates for industrial applications.

2. Cement

MLM also operates a cement business, primarily in Texas. This segment includes the production of Portland and masonry cement, which are critical for building foundations, bridges, and other infrastructure projects. The cement segment complements the aggregates business by providing a vertically integrated solution for customers.

3. Magnesia Specialties

This segment focuses on the production of magnesia-based chemicals and dolomitic lime products. These materials are used in a variety of industrial applications, including steel production, environmental remediation, and agriculture. Key products include:

  • High-purity magnesia for industrial processes.
  • Dolomitic lime for soil conditioning and water treatment.

Business Model

Martin Marietta Materials operates a vertically integrated business model that combines the production of raw materials with value-added services. The company owns and operates quarries, cement plants, and distribution facilities, ensuring control over the entire supply chain. Revenue is generated through the sale of aggregates, cement, and magnesia specialties to a diverse customer base, including government agencies, contractors, and industrial manufacturers. MLM also benefits from long-term contracts and strategic partnerships, which provide a stable revenue stream.
