Direct peers

• Vulcan Materials Company: Largest U.S. producer of construction aggregates (crushed stone, sand & gravel) and a major downstream asphalt and concrete operator — the closest pure-play aggregates peer to National Lime and Stone's core business model.
• Martin Marietta Materials: Top-tier U.S. aggregates producer with vertically integrated cement, asphalt and ready-mix businesses — directly comparable in scope, vertical integration, and DOT/spec-driven customer base.
• Summit Materials: Vertically integrated construction materials company combining aggregates, cement, ready-mix concrete, and paving — overlapping with National Lime and Stone's full-stack aggregates-to-paving model in regional U.S. markets.
• Rogers Group: Privately held, family-influenced U.S. aggregates and asphalt producer operating quarries and plants across the Midwest and Southeast — structurally similar in size, ownership profile, and product mix to National Lime and Stone.
• Carmeuse: Global, family-controlled lime and limestone producer with a strong North American footprint in high-purity limestone and dolomitic products — directly comparable on the lime/dolomite heritage and specialty minerals portfolio that includes NatMag99 and glass-batch dolomite.
• United States Lime & Minerals: Public, Texas-based producer of lime and high-purity limestone products serving steel, glass, construction, and agriculture — a focused comp for the dried-minerals and specialty-limestone portion of National's portfolio.
• New Enterprise Stone & Lime Co. Privately held Pennsylvania aggregates, lime, and paving producer — comparable on regional Northeast/Midwest aggregates exposure, vertically integrated paving, and private-company operating profile.
• Luck Stone: Privately held regional aggregates producer operating across the Mid-Atlantic and Southeast U.S. — comparable on private, family-influenced ownership and aggregates-led strategy, though less vertically integrated.

Broad incumbents

• CRH plc: Global building materials leader with substantial aggregates, asphalt, and concrete operations across North America — overlapping in segments but vastly broader in scale and geographic reach.
• Holcim: One of the world's largest cement and aggregates producers with significant U.S. presence — a broader incumbent whose U.S. aggregates, ready-mix, and paving operations overlap with National's integrated model.
