MLM vs ADM Comparison

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.

Archer-Daniels-Midland is a major processor of oilseeds, corn, wheat, and other agricultural commodities. The company is also one of the largest grain merchandisers through its extensive network of logistical assets to store and transport crops around the globe. ADM also runs a nutrition business that focuses on both human and animal ingredients and is a large producer of corn-based sweeteners, starches, and ethanol.
