Martin Marietta Materials, Inc. (NYSE: MLM) reported its second-quarter 2025 financial results, showing a robust performance across its key business segments. The company's revenue for the quarter ended June 30, 2025, was $1.81 billion, up 2.7% year-over-year (YoY) compared to the $1.764 billion reported in the same period last year. This performance was driven by strong demand across primary end markets, particularly in infrastructure and nonresidential construction.

The company's earnings per share (EPS) for the quarter was $5.43, up from $4.76 in the same period last year, reflecting a 14% increase. This improvement was supported by sustained pricing momentum and effective cost management, which contributed to higher gross profit and net earnings.

Key metrics such as average unit sales price, total shipments, and revenues for building materials, cement, and aggregates were mostly in line with estimates. The aggregates product line, which includes shipments and average selling price per ton, showed a slight decrease in shipments by 1% but an increase in average selling price by 7.4% compared to the prior year. This resulted in a 9% increase in aggregates gross profit and a 94 basis point expansion in gross margin.

Martin Marietta's Magnesia Specialties business achieved record quarterly revenues of $90 million, with gross profit increasing by 32% and gross margin improving by 605 basis points. This performance was driven by strong pricing, improved lime shipments, and operational reliability and efficiency gains.

The company also reported record quarterly aggregates revenues and second-quarter records for aggregates profitability, Adjusted EBITDA, and Adjusted EBITDA margin. These records underscore the company's pricing strength and cost discipline.

Martin Marietta's shares have returned +5.5% over the past month, reflecting investor confidence in the company's strong performance and strategic initiatives. The company's full-year 2025 Adjusted EBITDA guidance has been increased to $2.30 billion at the midpoint, reflecting the positive impact of acquisition contributions and current shipment trends.

The company continued its portfolio refinement, entering into a definitive agreement with Quikrete Holdings, Inc. for the exchange of certain aggregates operations for its Midlothian cement plant and related assets. Additionally, the company completed the acquisition of Premier Magnesia, LLC, a producer of magnesia-based products.

These strategic moves, along with the company's strong first-half performance, position Martin Marietta for continued growth and resilience through demand cyclicality. The company's disciplined execution of its proven strategy and deep experience navigating through cycles solidify its foundation for delivering superior shareholder value creation.
