Vulcan Materials 

Vulcan Materials is the largest producer of construction aggregates in the US. The company produced around 228 million tons of aggregates in 2025 and has 16.6 billion tons of proven and probable reserves, equivalent to roughly 83 years of supply at current production levels. Over the past several years, Vulcan has increasingly focused its portfolio on aggregates while reducing its exposure to downstream businesses such as ready-mix concrete and asphalt. The company operates across 23 US states, with additional operations in Mexico.
