Aggregate shipments dropped slightly in the second quarter at Martin Marietta, but the company made a series of key financial gains in the period.
Average selling price per ton of aggregates was up 7 percent in the quarter. In aggregates, Martin Marietta also made gains in revenues (up 6 percent), gross profit (up 9 percent) and gross profit per ton (up 10 percent).
Companywide, Martin Marietta’s revenues were up 3 percent in the second quarter while its gross profit increased 5 percent. Adjusted second-quarter EBITDA (earnings before interest, tax, depreciation and amortization) climbed 8 percent across the full business.
“Our company’s second-quarter performance is a testament to the value-added benefits of our geography and durable products,” says Ward Nye, chair and CEO of Martin Marietta. “As a result, we established record quarterly aggregates revenues and second-quarter records for aggregates profitability, adjusted EBITDA and adjusted EBITDA margin, as sustained pricing momentum and effective cost management continue to yield strong results.
“Additionally, our magnesia specialties business achieved record quarterly revenues and second-quarter records for gross profit and gross margin,” Nye adds. “Importantly, the first six months of 2025 represented the lowest total reportable incident rate in Martin Marietta’s history.”
According to Nye, materials demand across Martin Marietta’s primary end markets is varied.
“Infrastructure activity remains robust, underpinned by sustained record levels of federal and state investment,” he says. “In nonresidential, accelerating data center development and a warehouse recovery are contributing positively to near-term demand, partially offsetting relative softness in interest rate-sensitive light commercial construction. We expect residential construction demand to remain subdued until ongoing affordability headwinds improve.”
