Martin Marietta Materials (NYSE:MLM) reported record third-quarter performance as acquisitions offset softer organic aggregates shipments and higher energy costs, while executives cautioned that pressure on the company’s legacy operations would continue into the fourth quarter.
The building materials company updated its 2026 guidance midpoints to $7.8 billion in revenue and $2.48 billion in adjusted EBITDA. Chief Executive Officer Ward Nye said stronger acquisition contributions were partly offset by lower near-term expectations for the heritage business, including softer shipments and unfavorable price-cost dynamics.
The acquisition of Lhoist North America, completed Aug. 21, contributed $216 million in revenue and $115 million in cash gross profit through Sept. 30, ahead of the company’s initial expectations. Nye said integration was on track and that Martin Marietta expected opportunities to cross-sell aggregates and lime to customers.
Aggregates Growth Driven by Acquisitions
Third-quarter aggregates revenue rose 14% to a record $1.7 billion, while cash gross profit increased 6% to $696 million, Chief Financial Officer Michael Petro said. Acquisitions more than offset a $25 million decline in organic cash gross profit.
Aggregates shipments increased 15.9% to 67.1 million tons, although organic shipments fell 1.1%. Excluding acquisition and geographic mix, organic pricing rose 2.7%.
Costs rose faster than pricing. Cost of goods sold per ton, excluding external pass-through freight, increased 5.6%, or 5.1% organically, primarily because of higher diesel and other energy-related expenses. Excluding the diesel headwind, the respective increases would have been 3% and 2.6%, Petro said.
The specialties business generated record quarterly revenue of $362 million and cash gross profit of $163 million, including Lhoist’s contribution. Companywide free cash flow rose 18% to a third-quarter record of $426 million.
Pricing Outlook and Fourth-Quarter Pressure
For 2027, Martin Marietta expects mid- to high-single-digit growth in mix-adjusted aggregates pricing and mid-single-digit growth in reported average selling prices. Nye said the outlook reflects communicated January price increases, pricing on newly quoted work and carryover from increases at acquired businesses.
Acquired operations have lower average selling prices than Martin Marietta’s heritage business, which will temper reported pricing growth in the first half of 2027, particularly before the May 15 anniversary of the New Frontier Materials acquisition, Nye said. He added that the company typically needs about 36 months after an acquisition to bring pricing closer to its own average.
Petro said the company expects margin expansion next year as pricing, cost management, network optimization and a full year of Lhoist earnings more than offset continued inflation. He said an analyst’s estimate of a 3% to 4% increase in cost per ton was “in the general ZIP code,” assuming diesel remains near current levels.
For the fourth quarter, Petro said guidance implies a high-single-digit decline in organic volume and approximately 2% pricing growth on a reported organic basis. He expects pricing to remain below cost inflation in the quarter, before organic price-cost trends turn positive early in 2027.
Nye said some ready-mix customers found it difficult to absorb midyear increases in 2026 amid weak residential and private nonresidential demand. For 2027, Martin Marietta plans to treat increases in January or April, depending on geography, as the only increase during the year for those customers.
Infrastructure and Data Centers Support Demand
Nye described infrastructure as the company’s most resilient and aggregates-intensive end market. He said 40% of Infrastructure Investment and Jobs Act funding remains to be spent, and transportation budgets in many key states remain historically elevated.
During the question-and-answer session, Nye said Martin Marietta had not seen delays in state project lettings and did not expect funding issues in its most important states in 2027. He said further federal continuing resolutions were possible as lawmakers work toward a longer-term transportation authorization.
Private construction was more mixed. Shipments to data center projects more than doubled in the third quarter from a year earlier, and Nye cited power generation and warehouses as other areas of relative strength. Together with infrastructure, those markets account for approximately half of the company’s aggregates shipments.
By contrast, single-family residential and light nonresidential construction softened in September and October as interest rates rose. Nye said he did not expect a near-term recovery in those markets without meaningful improvement in affordability and financing conditions.
Lhoist Earnings and Debt Reduction
Martin Marietta expects Lhoist to contribute about $290 million in EBITDA across the portion of the third quarter after closing and the fourth quarter, Petro said. Nye projected approximately $820 million in Lhoist EBITDA for 2027, with earnings distributed relatively evenly across the year.
The company funded the cash consideration for the transaction with a $1.5 billion prepayable term loan and $5.5 billion in senior notes. Petro reiterated a target of reducing net debt to 2.0 to 2.5 times adjusted EBITDA while retaining investment-grade credit ratings. Nye said the company planned approximately $500 million in debt repayments in the coming weeks.
Chief Operating Officer Chris Samborski said Martin Marietta had taken network optimization actions in roughly half its divisions after starting the work in the West Division last year. The program can reduce operating expenses, capital spending and inventory, he said, while leaving the company able to restart idled sites when demand warrants.
