Martin Marietta is a leading US producer of construction aggregates, having produced roughly 200 million tons in 2025. Its aggregate reserves represent approximately 85 years of supply at 2025 production levels.

The company operates across 28 states, with smaller operations in Canada and the Bahamas.
