Core Business and Aggregates Focus

The Building Materials business reports revenues and gross profit from these product lines. Company releases describe separate performance for aggregates, cement and ready mixed concrete, and asphalt and paving, indicating distinct but related product categories within the overall building materials portfolio.
In addition to supplying materials, Martin Marietta’s public filings and news releases discuss factors that influence building materials demand, such as infrastructure activity, nonresidential construction and residential construction. These references show that the company’s products are closely tied to construction spending in the markets it serves.
