MARTIN MARIETTA MATERIALS INC has recently released its 10-Q report. Martin Marietta is a natural resource-based building materials company that supplies aggregates and other heavy-side materials to construction markets in the United States, Canada and The Bahamas. It operates through two building materials segments, East Group and West Group, and also has a Specialties business that produces magnesia-based products and dolomitic lime.
The company said its network included about 500 quarries, mines and distribution yards across 29 states, Canada and The Bahamas as of June 30, 2026. Its Building Materials business covers aggregates, asphalt, paving services and ready mixed concrete, with products used in infrastructure, nonresidential and residential construction, plus railroad, agricultural, utility and environmental applications. The Specialties business makes magnesium sulfate, magnesium oxide, magnesium hydroxide and dolomitic lime for uses including steel production, soil stabilization, flame retardants, wastewater treatment and pulp and paper production.
In the second quarter, total revenue rose to $1.947 billion from $1.609 billion a year earlier. Building Materials revenue increased to $1.795 billion from $1.519 billion, while Specialties revenue climbed to $152 million from $90 million. Gross profit was $495 million, essentially flat with $496 million a year earlier, while net earnings from continuing operations attributable to Martin Marietta fell to $256 million, or $4.26 per diluted share, from $292 million, or $4.84 per diluted share.
Aggregates revenue in the quarter reached $1.533 billion, up 16% from $1.320 billion. Shipments increased 17% to 61.6 million tons from 52.7 million tons, while average selling price slipped 2% to $22.74 per ton from $23.21. Organic shipments were 53.8 million tons, up 2.3%, and organic average selling price was $23.70 per ton, up 2.1%.
Aggregates gross profit declined to $418 million from $430 million. The company said the drop reflected a $52 million charge tied to the sale of acquired inventory marked up to fair value in acquisition accounting, along with higher depreciation, depletion and amortization expense. Aggregates depreciation, depletion and amortization rose to $166 million from $125 million.
Other Building Materials revenue increased 12% to $303 million, but gross profit fell 14% to $34 million from $39 million. Martin Marietta cited higher ready mixed concrete raw material costs, lower organic paving revenues and reduced job margins.
Specialties posted second-quarter revenue of $152 million, up from $90 million, and gross profit of $50 million, up 39% from $36 million. The company attributed the improvement to the July 2025 Premier Magnesia acquisition and organic pricing gains across all products.
For the first six months, total revenue increased to $3.309 billion from $2.771 billion. Building Materials revenue rose to $3.015 billion from $2.594 billion, and Specialties revenue increased to $294 million from $177 million. Gross profit was $805 million, down slightly from $811 million, and net earnings from continuing operations attributable to Martin Marietta were $336 million, or $5.56 per diluted share, compared with $396 million, or $6.52 per diluted share.
Six-month aggregates shipments totaled 105.5 million tons, up 15% from 91.7 million tons. Revenue from aggregates increased to $2.675 billion from $2.322 billion, while average selling price per ton edged down to $23.14 from $23.45. Organic shipments were 95.7 million tons, up 4.3%, and organic average selling price was $23.85, up 1.7%.
For the first half, aggregates gross profit declined to $706 million from $726 million. The company said the result was affected by a $73 million charge linked to the sale of acquired inventory marked up to fair value, plus higher depreciation, depletion and amortization. Aggregates depreciation, depletion and amortization rose to $298 million from $237 million.
Other Building Materials revenue increased 7% to $420 million, while gross profit slipped to $18 million from $21 million. Specialties revenue rose to $294 million from $177 million, and gross profit climbed to $95 million from $74 million.
Martin Marietta said consolidated SG&A was 5.9% of revenue in the second quarter, down from 6.5% a year earlier, and 7.5% for the first six months, down from 8.3%. The effective income tax rate for continuing operations was 23.3% for the first half, compared with 20.3% a year earlier.
The company also reported that the Midlothian cement plant, related cement terminals and Texas ready mixed concrete plants were treated as discontinued operations through their February 2026 divestiture date. Those businesses generated net earnings of $1.4 billion in 2026, including a $1.4 billion after-tax gain on divestiture, compared with $48 million in 2025. As a result of these announcements, the company's shares have moved -5.81% on the market, and are now trading at a price of $536.55.
