What does Vulcan Materials (VMC) do?

Vulcan Materials is the largest producer of construction aggregates in the United States. Aggregates (crushed stone, sand, gravel) are the fundamental inputs to concrete, asphalt, and road base used in virtually every construction project. The business is local and economic: aggregates are heavy and expensive to transport relative to their value, so each Vulcan quarry serves a relatively local market (typically 50-100 miles depending on transport mode). This creates regional pricing power.
