Roughly 40-50% of aggregates demand is tied to multi-year government infrastructure programs, including IIJA-funded projects, providing a more stable demand floor than a fully private-construction business. The remaining private-market exposure makes full-year volumes and revenues meaningfully sensitive to the construction cycle, as demonstrated by the FY2024 revenue decline from the FY2023 peak.

Aggregates represented 88% of total reportable segment gross profit in FY2025, with cement, asphalt, and ready-mixed concrete contributing the remainder. The Quikrete asset exchange in Q1 2026 further concentrated the portfolio toward aggregates, reducing the already modest secondary product contribution and creating deliberate single-segment focus.

Operations span 28 U.S. states, Canada, and The Bahamas, but the top 10 states generated 76% of Building Materials revenues, with Texas, North Carolina, and Colorado among the largest contributors. International operations in Canada and The Bahamas are immaterial to consolidated revenue, leaving the company predominantly exposed to U.S. construction cycles and federal infrastructure policy.

Each quarry site carries significant fixed infrastructure (crushing equipment, processing facilities) that generates operating leverage on incremental tonnage within a given delivery radius. Geographic expansion requires new quarries, which are capital-intensive, permit-constrained, and multi-year processes, limiting the pace at which the company can scale into new markets.

Infrastructure demand (road and highway construction, data centers) is relatively non-discretionary and essential for project completion, supporting above-average revenue quality for roughly 40-50% of volumes. Private residential and nonresidential demand is more discretionary, and aggregates are transactional rather than contractual, which moderates the overall quality of the revenue base.
