Vulcan Materials Co. (VMC)

Vulcan Materials operates primarily in the United States and is the nation's largest supplier of construction aggregates, mainly crushed stone, sand and gravel, and a producer of the aggregates-intensive products made from them, asphalt mix and ready-mixed concrete. In 2025 it ran 425 active aggregates facilities, 71 asphalt facilities and 76 concrete facilities, the latter two across Alabama, Arizona, California, Maryland, New Mexico, Tennessee, Texas, Virginia, the United States Virgin Islands and Washington D.C. There are three operating and reportable segments matching those product lines. The ten largest revenue-producing states were 90% of 2025 revenues and the top five were 63%, led by California, Texas, Georgia, Tennessee and Virginia. Production and sales are halted at the Calica operations in Mexico and Puerto Cortés in Honduras.

Where the demand comes from

Demand follows construction activity and moves with population, employment and household formation, so the strategy has been to build presence in the fastest-growing metropolitan areas and sell assets outside that plan. The coast-to-coast footprint serves 34 of the 50 highest-growth metropolitan statistical areas across 23 states and Washington D.C. The products go under highways, walkways, airport runways, parking lots and railroads, into water filtration, purification and erosion control, and into houses, apartments, bridges, schools, hospitals, commercial buildings, data centres, sewer systems and power plants.

Reserves and the distance problem

The company holds 16.6 billion tons of proven and probable aggregates reserves, placed near areas expected to need large volumes, and zoning and permitting rules make new entry hard in many metropolitan markets, which raises the value of existing sites. Aggregates carry a high weight-to-price ratio, so transport is costly relative to the material and production sits close to where the material is used. Approximately 80% of total aggregates shipments go straight from the producing location to the customer by truck, approximately 15% reach a sales yard by rail or water before a truck completes the trip, and less than 5% go directly by rail or water. Along the Gulf Coast and Eastern Seaboard, where local high-quality supply is limited, quarries with long-haul access serve those markets by barge, rail and a fleet of Panamax-class self-unloading ships, and a quarry in British Columbia supplies California and Hawaii under a long-term marine shipping agreement. A truck holds 20 to 25 tons, a railcar four to five truckloads, a barge 65 truckloads and an ocean vessel 2,500.

Asphalt and concrete

Aggregates make up approximately 95% of asphalt mix by weight and 80% of ready-mixed concrete by weight, and in both cases they come mainly from the company's own operations. Asphalt mix is produced and sold in Alabama, Arizona, California, New Mexico, Tennessee and Texas, with construction paving services in Alabama and Tennessee. Asphalt operations in California were added in 2024, and in 2025 the asphalt mix and paving operations in the greater Houston market were sold to keep the portfolio aggregates-led.

Competitors and customers

The industry is fragmented, with a large number of small privately-held companies; the ten largest producers were approximately 35% of total United States aggregates production in 2025 and Vulcan's own share is approximately 10%. Other public companies among the ten largest include Arcosa, Amrize, Cemex, CRH, Heidelberg Materials, Knife River and Martin Marietta. There are limited substitutes for quality aggregates, since recycled concrete and asphalt meet only some technical specifications. No single customer matters much: the five largest were approximately 7% of total revenues in 2025 and none was above 2%. Historically 40% to 55% of aggregates shipments have gone into publicly-funded construction, though relatively little is sold directly to government bodies.

Seasons and people

Almost everything is produced and consumed outdoors, so weather moves production and sales volumes, and quarterly results do not indicate the year: sales and earnings are normally highest in the third quarter and lowest in the first. At 1 January 2026 the company employed 11,172 people in the United States, 1,057 of them represented by labour unions, plus 280 in Mexico, 63 in Canada, 32 in Honduras and one in the Bahamas, of whom 218 are union represented.
