Martin Marietta Materials delivered a strong second quarter in 2026, underscoring the resilience of the U.S. construction materials market as infrastructure investment and heavy nonresidential projects continued to fuel demand for aggregates across North America.
The Raleigh, North Carolina-based building materials producer reported record second-quarter revenue of $1.95 billion, a 21% increase from the same period last year, driven by higher shipment volumes, strategic acquisitions and continued activity in infrastructure construction.
The company also raised its full-year revenue outlook, signaling confidence that public infrastructure spending and large commercial developments will continue supporting demand through the remainder of the year.
While reported operating earnings softened due to acquisition-related accounting charges, Martin Marietta‘s underlying business remained healthy, with Adjusted EBITDA rising 13% to a record $638 million, reflecting the company’s ability to generate strong cash flows despite integration costs.
Infrastructure projects remain the growth engine
Martin Marietta’s latest results reinforce a trend that has been evident across the U.S. construction industry throughout 2026: infrastructure spending continues to outperform many other construction segments.
The company’s aggregates business—the largest contributor to revenue—benefited from sustained demand from highways, bridges, transportation projects and heavy nonresidential construction.
Aggregate shipments reached a record 61.6 million tons, representing a 17% year-over-year increase.
Management attributed the growth to both recently acquired operations and organic demand, with infrastructure and industrial projects providing a steady stream of material requirements across much of the company’s operating footprint.
Although the average selling price per ton declined slightly because newly acquired operations shifted the overall product mix, organic pricing continued to improve, indicating that underlying market conditions remain favorable.
Acquisition strategy expands Martin Marietta’s footprint
Beyond organic growth, Martin Marietta continues reshaping its portfolio through acquisitions.
During the quarter, the company completed the acquisition of New Frontier Materials, strengthening its aggregates position along the strategically important I-70 corridor serving the greater St. Louis metropolitan region.
Even more significant was the announcement of a definitive agreement to combine with Lhoist North America, a transaction valued at approximately $13.5 billion.
If completed, the deal would substantially expand Martin Marietta’s presence in lime and industrial minerals while creating one of North America’s largest producers of limestone-based products.
According to the company, the proposed combination aligns with its long-term SOAR 2030 strategy by broadening exposure to infrastructure, manufacturing and industrial markets while leveraging its expertise in quarrying and mineral resource management.
The transaction is expected to close during the second half of 2026, subject to regulatory approvals, and is not included in the company’s current financial guidance.
Operational efficiencies strengthen outlook
Another notable takeaway from the earnings report is Martin Marietta’s focus on improving operational efficiency.
The company announced that an enterprise-wide review had identified approximately $350 million in annualized cash-flow improvement opportunities through optimization of its operating network, asset base and capital spending.
Management also said it has already unlocked more than $200 million in cash improvements during the first half of the year through disciplined inventory management and lower capital expenditures.
These initiatives are expected to strengthen cash generation as the company integrates recent acquisitions and prepares for its planned expansion into industrial minerals.
Revenue guidance raised
Reflecting confidence in construction demand, Martin Marietta increased its full-year revenue forecast to between $7.2 billion and $7.4 billion, while reaffirming its Adjusted EBITDA guidance of $2.36 billion to $2.50 billion.
The improved outlook suggests management expects infrastructure funding, industrial investment and heavy construction activity to remain supportive despite broader economic uncertainty.

Key Q2 2026 financial highlights
Industry outlook
Martin Marietta’s results add to growing evidence that infrastructure investment remains one of the strongest drivers of demand for construction materials in North America.
Large transportation programs, manufacturing expansions, energy projects and industrial developments continue to require significant volumes of aggregates, crushed stone and specialty mineral products.
These markets are proving more resilient than residential construction, helping major building materials producers maintain growth despite higher interest rates and ongoing economic uncertainty.
The company’s aggressive acquisition strategy also reflects increasing consolidation within the construction materials industry as producers seek larger reserve bases, expanded geographic coverage and greater operational efficiency.
With record shipment volumes, improved revenue guidance and plans to significantly expand its industrial minerals business, Martin Marietta appears well positioned to benefit from the next phase of North America’s long-term infrastructure investment cycle.
