Vulcan Materials: Rock On - [Business Breakdowns, REPLAY]

How Vulcan Turns Crushed Rock Into Durable Cash Flow

Vulcan Materials is a case study in why a mundane commodity business can compound. Rock is cheap but heavy, so transport costs make quarries local monopolies and protect incumbents from distant competition. Vulcan owns 400 quarries within reach of 60% of the US population and earns nearly all its gross profit from aggregates. It uses pricing discipline and technology to turn each incremental ton into cash, then buys nearby quarries with cash and debt.

Takeaways

• Local position drives aggregates margins. Rock sells for $10 to $20 a ton, but trucking costs $0.25 per ton mile and doubles every 40 miles. Markets with one to four producers earn 25% to 40% margins, versus 10% to 25% with five or more.
• Aggregates produce nearly all gross profit. Aggregates are 60% of sales but 90% of gross profit, with gross margins of 38% to 40% against 10% to 15% for concrete and asphalt. Incremental EBITDA margins run near 60%, and Vulcan converts 75% to 100% of net income into free cash flow.
• Pricing power rests on industry discipline. USGS data since 1900 shows long-term volume growth near 3% and price growth of 2% to 3%. Over the last decade volume grew about 2% and prices about 4%. Producers raise prices together, and Martin Marietta's value over volume strategy lifted prices more than 20%.
• Vulcan owns 400 quarries near demand. The company operates roughly 400 quarries within reach of 60% of the US population and holds about 16bn tons of reserves, a 60-year supply. Public infrastructure is about half of demand, while residential and nonresidential each take around 25%.
• Technology and scale cut operating costs. Vulcan monitors customer inventory, gives truckers an iPad app, builds digital twins of crushers and runs geological surveys before opening quarries. A national Caterpillar relationship gives Vulcan a 5% to 10% equipment cost advantage. A facility can shut in 15 minutes, unlike a cement kiln.
• Risks are capital allocation and policy. Hansen flags capital allocation, weather, government policy and the lack of substitutes for aggregates. He says Vulcan suits a set-it-and-forget-it investor, that mundane businesses can be excellent, and that a bad cycle is often the moment to buy.

Vulcan's acquisition playbook

• Buy small family-owned quarries that fit existing local markets, then improve pricing and operations.
• Finance deals with cash and debt while keeping leverage at 2 to 2.5 times.
• Florida Rock in 2006 added mid-Atlantic assets and cement facilities. Vulcan later sold the cement operation for about $800m after a five-year wait.
