Thematic Exposure -- 8/10

#1 US Aggregates Producer -- 400+ Quarries -- 15.8B Tons of Reserves -- 5-10 Year Permitting Moat

Aggregates are the textbook natural monopoly/oligopoly. The economics are stark: heavy product ($10-15/ton) with an economically viable trucking radius of just ~30-50 miles, creating hundreds of local markets each with 1-3 dominant suppliers.

Permitting moat: New quarry permits take 5-10+ years and face intense NIMBY opposition, especially near growing metro areas. This barrier is hardening, not softening, over time. VMC holds 400+ quarry locations with 15.8 billion tons of reserves.

Competitive landscape: VMC is #1, Martin Marietta is #2, followed by CRH, Heidelberg, and Summit Materials. The top 5 hold ~25-30% nationally, but in any given local market, concentration is far higher -- often 2-3 players control 60-80%+.

Pricing power evidence: Mix-adjusted pricing grew +6% in FY2025, with management guiding +4-6% for 2026. Prices rarely decline even in downturns -- they just slow. Cash gross profit per ton compounded from ~$6.80 three years ago to $8.66 in 2025, a ~27% increase on muted volume growth.

Oligopoly gate: PASS (Strongest possible outcome). The moat is geological and regulatory -- it does not erode with technology disruption. VMC divested California ready-mix and construction services in 2025, further concentrating on the highest-moat aggregates business.

~$350B IIJA Highway Funds -- VMC Market Starts +80% Since Inception -- Peak Spending Phase (Years 4-5)

The IIJA provides ~$350B for federal highway programs over FY2022-2026. Through December 2025, states committed $249B to 113,000+ projects, but over 50% of total IIJA funds remain unspent and will flow through 2026-2028+.

VMC markets outperforming national averages: Trailing 12-month highway starts in Vulcan-served markets are up 24% YoY. Since IIJA inception, VMC market starts are up 80%. All top 10 VMC-relevant DOTs have increased FY2026 budgets.

State-level funding is additive: California highway starts +47% in 2025 vs 2024. Southeast states (AL, GA, SC, TN) seeing significant jumps in bookings. Non-highway public works (ports, airports, beach restoration) also growing -- 14 of 19 VMC GM areas seeing double-digit increases in non-highway public starts.

Long tail beyond 2026: IIJA authorization expires Sept 30, 2026, but management expects reauthorization. Even without it, unspent dollars provide 2-3 years of continued public demand growth. The SPEED Act (potential successor) is already being discussed.

Sub-score: 9/10. VMC is a direct, high-leverage beneficiary of the largest US infrastructure spending cycle in decades. The timing is ideal -- IIJA is now in the heaviest spending phase, and VMC Sun Belt footprint over-indexes to the fastest-growing state DOT programs.

150M+ Sq Ft Under Construction -- 70%+ Geographic Overlap With VMC Facilities -- Multi-Year Runway

The data center / AI buildout is a generational demand tailwind for VMC. 150M+ sq ft of data centers are under construction with nearly 450M sq ft announced or planned. The global data center construction market is ~$275B in 2025, projected to grow ~12% CAGR through 2034.

Geographic overlap is exceptional: Over 70% of US data center activity is occurring within 30 miles of a Vulcan aggregates facility. Data centers cluster near population and power infrastructure, which is exactly where VMC quarries sit.

Aggregate-intensive projects: Each major data center campus requires large volumes of base stone (site prep/foundations) followed by clean stone (concrete/structural). Large projects (25,000+ tons) now represent ~45% of bookings, up from the historical ~30%, driven primarily by data centers.

Mix impact is temporary: Base stone (lower price per ton) ships first in DC projects; clean stone follows as buildings go vertical. Management guided that pricing will inflect higher through 2026 as this mix normalizes.

Cascading demand: Data centers are driving ancillary construction -- power generation, LNG projects, grid infrastructure, water/sewer -- all aggregate-intensive. VMC cited a $6B Eli Lilly manufacturing project as an incremental demand driver.

Sub-score: 8/10. Near-perfect geographic positioning with a multi-year runway. Temporary mix headwind is the only knock.

12 of 15 Fastest-Growing US Cities Are Sun Belt -- 86% of Top 50 In-Migration Zips in TX, FL, AZ

VMC is a pure play on Sun Belt growth. The footprint is concentrated in the Southeast and Southwest US -- the fastest-growing region of the country. 12 of the 15 fastest-growing US cities are Sun Belt, and 86% of the top 50 zip codes for net in-migration since 2020 are in TX, FL, and AZ.

Construction demand follows population: Sun Belt saw 500,000+ new multifamily units completed in 2024. Phoenix leads the nation in industrial development (33M+ sq ft under construction). Nashville, Atlanta, and Dallas-Fort Worth are posting ~8%+ industrial rent growth.

VMC Southeast markets are the healthiest in the portfolio with the highest unit margins. Management described them as "probably the healthiest" on the Q3 2025 earnings call.

Sub-score: 8/10. A slow-burn secular tailwind that underpins volume growth for the next decade+.

Single-Family Drag for 3 Years -- Flat-to-Modest 2026 Guide -- High Incremental Margins on Recovery

Single-family has been the notable drag on VMC volumes for 3 consecutive years. Same-store volumes were slightly negative in FY2025, masked by M&A contributions. Management is guiding flat-to-modest residential for 2026, assuming some help from interest rates and affordability.

This is upside optionality, not base case risk: If mortgage rates decline materially, VMC Sun Belt markets (TX, FL, GA, TN, AL, SC) would see outsized starts recovery. Aggregates pricing has proven resilient through the downturn, so a volume recovery flows through at high incremental margins. Multifamily is already showing green shoots in some VMC markets.

Sub-score: 6/10. Residential weakness is well-known and mostly priced in. Recovery would be a significant incremental positive, but the bull case does not depend on it.
