Business Model & Revenue
Revenue comes mainly from selling aggregates by weight, supplemented by cement, concrete, asphalt and paving activities. Prices, shipment volumes and product mix drive sales; freight distance matters because heavy materials are costly to transport. Public infrastructure funding, private construction and weather affect demand. Ownership of quarries and reserves supports long production lives, while energy, labor and logistics are major costs.
Key Facts & Market Position
The company concentrates on attractive regional markets where permitted reserves and transport links are difficult to reproduce. Aggregates are essential inputs but have a low value relative to their weight, making local supply positions important. Rail and water distribution extend selected quarries' reach, while permitting, land use and construction cycles constrain capacity and volumes.
