Vulcan Matls — Business Overview

What does Vulcan Materials do?

Vulcan Materials is the largest supplier of construction aggregates in the United States, operating three business segments built around crushed stone, sand, and gravel. The company runs 425 active aggregates facilities, 71 asphalt facilities, and 76 concrete facilities across the country. Its products are the basic raw materials that go into virtually every construction project — roads, bridges, homes, schools, hospitals, data centers, and airports.

The three segments, with their respective share of 2025 revenues and gross profit, are:

The exact revenue dollar splits by segment are referenced in Note 15 of the filing but not reproduced in Item 1. What the filing does make clear is that roughly 90% of gross profit comes from aggregates.

How does Vulcan Materials make money?

The core revenue engine is selling aggregates by the ton to construction contractors, builders, and government project operators. Customers — over 25,000 of them — buy crushed stone, sand, and gravel for use as base material under roads and runways, as inputs into concrete and asphalt, and for erosion control and railroad ballast. Because aggregates are heavy and cheap relative to their weight, customers almost always buy from the nearest source, giving local quarry operators strong pricing power within their delivery radius. Approximately 80% of Vulcan's aggregates are delivered by truck directly from the quarry to the job site.

The Asphalt and Concrete segments are essentially downstream extensions of the aggregates business, using internally produced stone as their primary input. Aggregates make up about 95% of asphalt mix by weight and 80% of ready-mixed concrete by weight. These segments buy aggregates from Vulcan's own quarries at market prices, which means the aggregates segment captures margin on both sides — as supplier and as a driver of downstream demand. From 2023 to 2025, aggregates gross profit per ton grew from $7.40 to $8.66, a 17% increase, showing improving unit economics.

Real estate and land management provide a secondary, non-operating income stream. With roughly 310,000 acres in its land portfolio, Vulcan generates proceeds from selling mined-out or surplus land. In 2023 alone, land sales in Virginia and Illinois generated over $80 million in pretax gains.

What market does Vulcan Materials operate in?

The U.S. construction aggregates industry is large, fragmented, and tied directly to population and infrastructure spending cycles. The industry consisted of approximately 5,000 companies operating around 11,000 facilities in 2025. Demand for aggregates rises and falls with construction activity, which in turn tracks population growth, employment, household formation, and government infrastructure spending. Long-term demand has historically recovered strongly after cyclical downturns.

Two powerful secular tailwinds are supporting demand right now. First, the Infrastructure Investment and Jobs Act (IIJA), signed in 2021, authorized nearly $350 billion in Federal-Aid Highway Program spending over five years (growing from $66.9 billion in FFY 2022 to $72.1 billion in FFY 2026), plus an additional roughly $550 billion in new infrastructure spending across rail, airports, water systems, and ports — all aggregates-intensive categories. Second, U.S. housing starts reached approximately 1.5 million units in 2025, still below the historical peak of over 2 million, suggesting room for continued residential demand growth. The company's projection that 76% of U.S. population growth between 2025 and 2035 will occur in Vulcan-served states underscores its positioning within these trends.

Who are Vulcan Materials' main competitors?

The aggregates industry is highly fragmented — the ten largest producers together account for only about 35% of total U.S. production, and Vulcan itself holds roughly 10% market share despite being the undisputed leader. This fragmentation means most competition is local, from thousands of small, privately-held quarry operators. The publicly traded peers among the top ten producers include Martin Marietta Materials, CRH plc, Heidelberg Materials, Cemex, Arcosa, Amrize, and Knife River Corporation.

Vulcan's primary competitive advantages are its reserve base, its geographic positioning, and its logistics network. It holds 16.6 billion tons of proven and probable reserves, strategically located near high-growth metropolitan areas. Because permitting and zoning regulations make it increasingly difficult to open new quarries near urban centers, existing reserves at well-positioned locations carry durable, hard-to-replicate value. On top of that, Vulcan manages logistics for nearly half of its own product shipments — using trucks, railcars, barges, and Panamax-class ocean vessels — giving it distribution reach that smaller, truck-only competitors cannot match.

Where does Vulcan Materials operate?

Vulcan is overwhelmingly a U.S. business, with operations concentrated in fast-growing Sun Belt and Mid-Atlantic states. Its top ten revenue-producing states in 2025 were California, Texas, Georgia, Tennessee, Virginia, North Carolina, Florida, Alabama, South Carolina, and Arizona — and together they accounted for 90% of total revenues. The top five alone represented 63%. The company operates in 23 states plus Washington D.C., serving 34 of the top 50 highest-growth U.S. metropolitan areas.

Outside the U.S., Vulcan has a limited and currently troubled international footprint. It has small aggregates operations in the Bahamas and British Columbia, Canada (which supplies markets in California and Hawaii via a marine shipping arrangement). Operations in Quintana Roo, Mexico (Calica) and Puerto Cortés, Honduras have been halted, and the Mexico situation involves an active NAFTA arbitration proceeding referenced in the filing. These international operations represent a small fraction of the business, but the Mexico dispute is a live legal and financial risk worth watching.
