What Martin Marietta does

Martin Marietta Materials, Inc. (NYSE: MLM) is an S&P 500 aggregates-led heavy building materials producer headquartered in Raleigh, North Carolina, operating 500+ facilities across 29 U.S. states, Canada, and The Bahamas. The company manufactures and distributes crushed stone, sand, and gravel aggregates — products that are heavy, low unit-cost, and transportation-cost-sensitive — alongside complementary downstream offerings including hot-mix, warm-mix, and cold-mix asphalt with full-service paving; ready-mixed concrete in commercial, institutional, residential, and specialty formulations; and high-purity magnesia-based specialty products via its Magnesia Specialties division. Customers include state and federal departments of transportation, hyperscale data center developers, energy project contractors, commercial/institutional builders, and residential contractors, with no individually named anchor customers representing outsized share.

The business model is primarily transaction-based unit pricing (average selling price of $23.30 per ton for aggregates in 2025) executed through direct facility sales, regional division offices (East, Central, Southwest, West), and project-specific supply arrangements. The go-to-market combines local field sales at each facility with enterprise-level pursuit of large infrastructure, data center, and energy projects supported by a facility-locator website, the eRocks online ordering platform, and an interactive product calculator. Aggregates now account for approximately 90% of profits following the 2026 Quikrete asset exchange that divested the last cement plant, marking the company as a near-pure-play aggregates operator under its SOAR 2030 strategy. FY2025 revenue was $6.150 billion (+9% year-over-year) with FY2026 guidance of $7.0-7.32 billion and a 2029 target of $8.2 billion in revenue and $1.7 billion in earnings, supported by record aggregates shipments, programmatic M&A, and infrastructure spending tailwinds from the IIJA and hyperscaler data center capex.

Direct peers

• Vulcan Materials Company: Vulcan Materials is the largest U.S. producer of construction aggregates and Martin Marietta's closest direct competitor, operating a similar network of quarries serving infrastructure, residential, and non-residential construction markets. Both companies are publicly traded pure-play aggregates platforms competing in overlapping geographies across the U.S. Sun Belt and Southeast.
• CRH plc: CRH is a global building materials leader with significant U.S. aggregates, asphalt, and ready-mixed concrete operations, making it a direct competitor to Martin Marietta in North America. Its broader geographic and product diversification overlaps heavily with Martin Marietta's aggregates-heavy portfolio.
• Summit Materials: Summit Materials produces aggregates, cement, and ready-mixed concrete across the U.S., with a focus on economically attractive, high-growth metropolitan areas. It competes head-to-head with Martin Marietta in several regional markets and has a similar vertical integration strategy across heavy building materials.

Broad incumbents

• Holcim Ltd: Holcim is one of the world's largest building materials producers with global aggregates, cement, and ready-mix operations, including a meaningful U.S. presence. While its portfolio is much more diversified than Martin Marietta's, it competes directly in U.S. aggregates and concrete markets and pursues similar M&A-led growth strategies.
• Heidelberg Materials: Heidelberg Materials is a major global cement and aggregates producer with North American operations competing with Martin Marietta in aggregates and downstream concrete products. Its broader portfolio across cement, aggregates, and ready-mixed concrete places it in direct competition in several Martin Marietta markets.
• Cemex S.A.B. de C.V. Cemex is a global building materials leader with significant U.S. cement, aggregates, and ready-mixed concrete operations. Its U.S. aggregates footprint competes with Martin Marietta across the Sun Belt and Southeast, though Cemex remains more weighted to cement than Martin Marietta.

Others

• Quikrete Holdings, Inc. Quikrete completed a major asset exchange with Martin Marietta in February 2026, acquiring the Midlothian cement plant and Texas ready-mix assets in exchange for ~20 million tons of aggregates capacity. It is a major North American concrete and cement producer and a strategic counterparty to Martin Marietta.

Emerging players

• Eagle Materials Inc. Eagle Materials produces cement, gypsum wallboard, and concrete products across the U.S. Although more focused on cement and wallboard than aggregates, it competes with Martin Marietta in select cement and concrete end markets and shares similar U.S. heavy-side materials exposure.

Regional players

• Granite Construction Incorporated: Granite Construction is a major U.S. infrastructure contractor and vertically integrated aggregates producer. While its primary business is construction services, its in-house aggregates operations overlap with Martin Marietta's customer base and compete for certain project supply opportunities, particularly in the western U.S.
• Boral Limited: Boral is an Australian-headquartered building materials and construction products company with North American aggregates and asphalt operations. While it does not directly compete with Martin Marietta in Australia, its U.S. asphalt and aggregate assets overlap with Martin Marietta's footprint, particularly in the Southeast and Southwest.
