Martin Marietta Materials reported record second-quarter 2025 aggregates revenues and second-quarter records for aggregates profitability, Adjusted EBITDA of $630 million, and Adjusted EBITDA margin of 34.8%. The company's Magnesia Specialties business also achieved record quarterly revenues of $90 million and second-quarter records for gross profit of $36 million and gross margin of 40%.
Aggregates shipments decreased 0.6% to 52.7 million tons, primarily due to softening demand in Colorado and wet weather, which largely offset strength in the Southeast and contributions from acquisitions. The average selling price for aggregates increased 7.4% to $23.21 per ton, driving a 9% increase in aggregates gross profit to a record $430 million.
Cash provided by operating activities for the first six months of 2025 was $605 million, a significant increase from $173 million in the prior-year period, partly reflecting deferred income tax payments. The company returned $547 million to shareholders through dividend payments and share repurchases during this period.
Martin Marietta confirmed its increased full-year 2025 Adjusted EBITDA guidance to $2.30 billion at the midpoint. This outlook incorporates the Premier Magnesia acquisition, completed on July 25, 2025, and accounts for the classification of assets involved in the Quikrete exchange agreement as discontinued operations starting in the third quarter of 2025.
