Country

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. Over the past several years, the company has increased its exposure to aggregates while reducing its presence in cement and downstream businesses such as concrete and asphalt. More recently, Martin Marietta expanded into an aggregate-adjacent business through its acquisition of Lhoist North America, the largest US producer of lime. The company operates across 28 states, with smaller operations in Canada and the Bahamas.
