Vulcan Materials produces and sells construction aggregates: crushed stone, sand and gravel used to build and maintain infrastructure and buildings. Customers use these materials as foundations for roads, runways, parking lots and railroads, and as ingredients in asphalt and concrete. Aggregates also have uses in water filtration and erosion control.
The company operates primarily in the United States. Its materials go into public projects such as highways, bridges, airports and water systems, as well as private construction including homes, factories, offices and data centers. It serves contractors and other customers directly and manages shipments for nearly half of its products. Materials reach customers by truck, rail, barge and ship.
Aggregates are Vulcan’s core business. It also makes asphalt mix and ready-mixed concrete in selected markets, generally using stone and sand from its own operations. The asphalt business includes paving services in Alabama and Tennessee. Because asphalt and ready-mixed concrete harden rapidly, they are generally delivered near the facilities where they are made.
Vulcan was founded in 1909 and is headquartered in Birmingham. Ronnie A. Pruitt is its chief executive officer. During 2025, the company operated 425 active aggregates facilities, 71 asphalt facilities and 76 concrete facilities.
How it makes money
Vulcan earns revenue by producing and selling aggregates, asphalt mix and ready-mixed concrete. Its three operating segments follow those product lines. The Aggregates segment crushes stone and sorts it into sizes suited to different uses; its products can be sold directly to customers or used by Vulcan’s downstream businesses. Transfers to the Asphalt and Concrete segments are made at local market prices for the grade and quality required.
The company’s aggregates sales include freight and delivery charges. It also tracks freight-adjusted revenues and prices, which exclude freight and delivery and certain other service revenues. In 2025, aggregates shipments increased 3%, or 6.9 million tons, to 226.8 million tons, while the freight-adjusted sales price increased 4.3%, or $0.90 per ton, to $21.98. Aggregates gross profit per ton increased 5% to $8.66 per ton.
Demand comes from ongoing construction and maintenance across public infrastructure and private buildings, but individual projects and order volumes vary with construction activity. The company says approximately half of its products are sold through a daily bidding process and the other half through fixed-plant business. Vulcan manages shipments for nearly half of its products, and transportation costs are passed along to customers.
In the third quarter of 2026, shipments decreased 3% year over year, while mix-adjusted average selling prices improved 5%. Vulcan said higher selling prices more than offset sharply higher diesel input costs in aggregates cash gross profit per ton.
2025 total revenue was $7,941.1 million; third-quarter 2026 adjusted EBITDA was $707 million. Adjusted EBITDA is a non-GAAP measure and is not quarterly revenue.
Customers and how it sells
Vulcan serves public and private construction markets and has over 25,000 customers. Publicly funded projects include highways, airports and government buildings; private work includes residential and nonresidential construction. Although approximately 40% to 55% of aggregates shipments have historically gone into publicly funded construction, a relatively small portion of sales is made directly to government agencies.
No single customer accounted for more than 2% of total revenues in 2025, and the five largest customers accounted for approximately 7%. The company ships materials directly from producing locations and also uses sales yards reached by rail or water. Approximately 80% of total aggregates shipments go exclusively by truck from the producing location to the customer.
Vulcan produces and sells aggregates and related products and services in 23 states, the U.S. Virgin Islands and Washington D.C., as well as local markets around operations in the Bahamas and Canada. Its top ten revenue-producing states accounted for 90% of 2025 revenues; its top five accounted for 63%. California, Texas, Georgia, Tennessee and Virginia were the top five.
Production and sales at Calica in Mexico and Puerto Cortés in Honduras are halted. In 2026, Vulcan added aggregates assets in Texas and Tennessee and expanded into southeastern Colorado and southern Ohio.
Suppliers and costs
Aggregates production relies on stone, sand and gravel from owned or leased reserves rather than purchased raw material. The process crushes stone and separates it through screens. It also requires explosives, fuel and electric power. Direct production costs include wages and benefits, depreciation and depletion, parts and supplies, repairs, maintenance and contracted services.
The Asphalt and Concrete segments obtain most of their aggregates from Vulcan’s own operations. Vulcan buys liquid asphalt cement from third-party producers. For ready-mixed concrete, it buys cement-related materials from a few suppliers in each major geographic market and generally buys chemical admixtures under national purchasing agreements.
Transportation is a cost because aggregates are heavy relative to their price. Vulcan passes transportation costs along to customers, and long-distance trucking can be prohibitive. The company can adjust operating hours to match demand, although extracting and producing aggregates requires substantial fixed capital.
Vulcan reported approximately $80 million of energy headwinds in the first nine months of 2026. It said those headwinds included diesel and increases in liquid asphalt costs, and expected about $120 million for the full year.

Competitive position
Vulcan competes in local aggregates markets against many small, privately held producers and other public companies. It estimates that its U.S. aggregates market share was approximately 10% in 2025 and that the ten largest producers accounted for approximately 35% of production. Publicly traded companies among those ten include Martin Marietta Materials, Amrize, Cemex, CRH, Arcosa, Heidelberg Materials and Knife River.
Aggregates are generally produced close to where they are used because their weight makes long-distance transportation costly. Vulcan also serves some markets through rail, barges and ships where local supplies are limited. Our reading: proximity to customers is a meaningful local advantage because freight costs can exceed the cost of the material, but its value depends on the location of each quarry and customer.
Vulcan has 16.6 billion tons of proven and probable aggregates reserves. Zoning and permitting restrictions can limit the expansion or development of quarries in metropolitan markets. Our reading: permitted reserves provide a meaningful barrier to entry in those markets, although the same restrictions can constrain Vulcan’s own expansion.
There are limited substitutes for quality aggregates; recycled concrete and asphalt can serve some applications but cannot meet every project’s specifications. Our reading: those specifications support demand for virgin aggregates, while recycling remains an alternative in some uses. Vulcan’s operations also share procurement, engineering and administrative resources across facilities.

Growth opportunities
Vulcan’s growth strategy combines improvements in its existing operations with acquisitions and new-site development. Its commercial and operating programs focus on selling, logistics, production efficiency and sourcing. The company also pursues acquisitions to enter or expand in local aggregates markets and selectively invests in complementary asphalt and concrete businesses.
Long-term aggregates demand is linked to population, employment and household formation, as well as public infrastructure investment. Vulcan serves both publicly funded projects and private construction, including data centers, manufacturing and energy projects. The company says its footprint serves 34 of the top 50 highest-growth metropolitan statistical areas in 23 states plus Washington D.C.
Vulcan completed two aggregates bolt-on acquisitions in the third quarter of 2026 and another in October. It added assets in Texas and Tennessee and entered southeastern Colorado and southern Ohio during the year. The company expects to remain focused on bolt-on aggregates acquisitions and to complete several more transactions before year-end.
The company received $572 million in cash proceeds from downstream and non-core divestitures through the first nine months of 2026 and redeployed approximately $300 million, primarily from the California concrete sale, into aggregates acquisitions. For 2027, Vulcan expects large projects to continue driving nonresidential activity, residential construction to remain challenged until affordability improves, and aggregates prices to grow mid to high single digits.

Structural risks
- Construction cycles: Sales and earnings are sensitive to national, regional and local economic conditions and swings in construction spending, particularly in the private sector. Vulcan says housing affordability and interest rates are limiting residential activity.
- Energy and inflation: Diesel and liquid asphalt costs have created energy headwinds. Vulcan also says inflation and trade measures can pressure customers and negatively affect shipment volumes.
- Fixed costs and shipments: Aggregates extraction and production require substantial fixed capital, making earnings sensitive to changes in product shipments. Weather and seasonal conditions also affect production and sales volumes.
- Reserves and permitting: Long-term operations depend on securing and permitting reserves in locations that can serve customers economically. Zoning, land-use and environmental rules can restrict quarry development or expansion.
- Public funding: Reductions in state and federal funding can curtail publicly funded construction. Vulcan also says inflation has reduced the volume of materials that infrastructure spending can fund.
- International operations: Production and sales remain halted at Calica in Mexico and Puerto Cortés in Honduras. Mexican government actions prohibit Calica from extracting construction materials from its properties.
Bottom line
Our reading
Vulcan is an aggregates-led construction materials business whose economics depend on local reserves, delivery distances and the volume and price of material sold. Its permitted sites and distribution network help it serve nearby projects, while construction cycles, public funding and energy costs affect demand and profitability. Acquisitions extend its reach, but growth also depends on developing reserves and maintaining access to markets.
