Overview
Vulcan Materials is the largest U.S. construction-aggregates supplier, with smaller asphalt and ready-mix operations. Its moat is concentrated in Aggregates: difficult-to-permit reserves near demand and high freight cost relative to stone value. The distribution footprint reinforces those assets but is not independently scored without delivered-cost or service evidence, while corporate scale lacks comparative unit-cost proof. Asphalt and Concrete are explicitly moatless because internal aggregates are transferred at local market prices and current disclosures do not show exclusive supply or persistent peer economics. Q2 2026 revenue was $2.156B and gross profit was $625.5M; Aggregates supplied 76.0% of external revenue and 90.7% of segment gross profit. At July 21, 2026, exactly 129,578,739 common shares were outstanding.

Q2 2026 segment sales were $1,763.0M, including $124.0M of intersegment sales, so external Aggregates revenue was exactly $1,639.0M or 76.0274608034% of $2,155.8M consolidated revenue. Segment gross profit was $567.3M, 90.7% of disclosed segment gross profit, and cash gross profit reached $12.02 per ton. No operating-profit share is stored because Vulcan's segment measure is gross profit. The 425-facility and trucking/rail/barge/ship footprint reinforces site access and delivered-cost reach, but current disclosure does not isolate a persistent network-density or corporate-scale advantage from reserve location, so the prior network-density and unit-cost claims are removed.

Evidence
Long development timelines, zoning and environmental permits, community resistance and finite geology restrict new quarries or expansion near growing metropolitan demand. Vulcan had 16.6B tons of proven and probable reserves and 425 active aggregates facilities at year-end 2025. The protection is site-specific: permitted competitors can expand, and rail, water or recycled supply can contest some markets.
Permits Rights Of Way moat: definition, examples, and stocks
Erosion risks
- Permitting or zoning reform materially increases quarry capacity
- Existing competitors expand already-permitted reserves
- Recycled aggregates substitute for virgin stone in eligible applications
Leading indicators
- Reserve replacement and remaining reserve life in core metros
- Permit approval timelines, expansion capacity and contested applications
- Competitor greenfield and brownfield capacity additions
Counterarguments
- The U.S. industry remains fragmented, with about 5,000 companies and 11,000 facilities in 2025
- Permitted local rivals can have comparable scarcity and proximity

Evidence
Aggregates' low value relative to weight makes truck haul distance economically decisive, localizing most competition around quarry sites. Approximately 80% of Vulcan shipments move directly from the producing location by truck. This mechanism is distinct from permitting: it protects a well-located reserve even when other reserves are legally available but too distant to compete on delivered cost.
Geographic Natural moat: definition, examples, and stocks
Erosion risks
- Lower freight costs or new rail and water links widen economic supply radii
- A nearby competing quarry opens or expands
- Construction demand shifts to metros outside Vulcan's footprint
Leading indicators
- Freight, fuel and trucking costs relative to material price
- Tons delivered directly by truck versus rail or water
- Delivered-price spreads and competitor proximity in key metros
Counterarguments
- Local markets can contain several similarly proximate quarries
- Vulcan itself demonstrates that rail, barge and ocean logistics can overcome distance in selected regions
Asphalt
Asphalt mix and paving services
Q2 2026 Asphalt revenue was exactly $330.0M or 15.3075424436% of consolidated revenue; gross profit was $49.8M at a 15% margin. Results exclude the Houston asphalt and construction business divested in Q4 2025. Aggregates are about 95% of asphalt mix by weight and are mainly supplied internally, but Vulcan's filing says intersegment aggregate sales occur at local market prices. No lower transfer cost, exclusive input access or persistent peer margin advantage is demonstrated, so the prior supply-chain-control claim is removed. No operating-profit share is stored because Vulcan reports segment gross profit.
Concrete
Ready-mixed concrete
Q2 2026 Concrete revenue was exactly $186.8M or the residual 8.6649967530% of consolidated revenue; gross profit was $8.4M. The quarter included two months of the California ready-mix operations before their early-June sale. Aggregates are about 80% of ready-mix by weight and mainly internally sourced, but intersegment aggregate sales occur at local market prices and cement may be the binding input. No exclusive supply or cost advantage is verified, so the prior supply-chain-control claim is removed. No operating-profit share is stored because Vulcan reports segment gross profit.
Evidence
New quarry sites often take years to develop
The filing directly identifies the time required before a new competing site can supply a local market.
increasingly difficult to permit new sites or expand existing sites due to community resistance
This supports an entry barrier attached to strategically located reserves, not a general regulatory advantage.
Aggregates have a high weight-to-price ratio that makes transportation expensive relative to the cost of the material
The filing explains why most aggregates markets are local and why proximity to demand affects delivered cost.
