Martin Marietta Materials Inc
A building-materials maker whose crushed stone, sand, gravel, and cement go into highways, homes, and airports across the U.S., Canada, and the Bahamas. Its name traces to a 1961 merger between aerospace pioneer Glenn L. Martin and the American-Marietta Corporation, while its quarries trace back to a 1939 stone company founded by two brothers in Raleigh, North Carolina. The company was spun off in the 1990s from the aerospace giant that later became Lockheed Martin.
Aggregates shipments rose 17% on QUIKRETE contributions, but a $52M inventory markup charge pushed aggregates gross profit down 3%.
Aggregates shipments rose 17%, the fastest growth in years, but the profit from those tons fell. rose 21% to $1.95 billion, yet from continuing operations declined 12% to $256 million as a $52 million acquired- and higher overwhelmed the volume gain. The company is growing its asset base through acquisitions, but the cost of integrating them is compressing margins right now.
Key takeaways
Aggregates fell 3% to $418 million despite a 17% increase in shipments, as a $52 million from the QUIKRETE asset exchange and higher expense more than offset organic pricing gains.
Consolidated rose 21% to $1.95 billion, with the Building Materials business up 18% to $1.80 billion and the Specialties up 69% to $152 million, both driven by recent acquisitions.
from continuing operations attributable to Martin Marietta were $256 million, or $4.26 per diluted share, down 12% from $292 million a year ago, including $45 million in after-tax acquisition, integration, and rationalization charges.

Management's Discussion and Analysis
Q2 2026 revenue rose 21% to $1.95B driven by acquisitions, but net earnings fell 12% on inventory markup charges and higher DD&A.
⌄
Total revenues increased 21% to $1.95B, with the Building Materials business up 18% to $1.80B and Specialties up 69% to $152M, both benefiting from recent acquisitions.
Aggregates declined 3% to $418M despite a 17% shipment increase, as a $52M acquired- markup charge and higher DD&A offset organic pricing gains.
from continuing operations fell to $406 million from $525 million a year ago, largely because of higher income tax payments tied to the gain on the QUIKRETE transaction.
The company amended its to accommodate the pending $13.5 billion Lhoist North America acquisition, with the maximum stepping from 4.75x down to 3.75x over time.
What changed
The Q1 2026 watch item on whether the 12.4% aggregates shipment growth was inflated by a partial-quarter QUIKRETE contribution is partly answered: Q2 shipments rose 17%, confirming the volume lift from the acquisition is real and extending into a full quarter.
The Q1 2026 watch item on the aggregates product and the $22 million proved prescient: the charge more than doubled to $52 million in Q2, and the aggregates gross margin fell to 25.4% from 30.8% a year ago, confirming the markup is a recurring drag as acquired sells through.
The Q1 2026 watch item on whether $37 million in after-tax deal charges represented the bulk of integration costs was also answered: Q2 added another $45 million in after-tax acquisition-related and rationalization charges, indicating these costs are continuing rather than one-time.
turned negative at -$16 million in Q2, down from positive $208 million a year ago, as declined and remained elevated, extending the pattern flagged in Q1 where free cash flow was only $41 million.
What to watch
Whether the $52 million acquired- subsides in Q3 2026 as the QUIKRETE is sold through, and whether the aggregates product recovers from 25.4% toward the 30%+ levels of prior quarters.
The pace of generation in the second half of 2026, given the first half produced only $25 million and the company carries $5.09 billion in while continuing to shares.
Whether the $45 million in after-tax acquisition, integration, and rationalization charges in Q2 2026 represents the peak of deal-related costs, or if additional charges will continue to weigh on reported earnings as the Lhoist North America acquisition approaches.
The trajectory of the pending $13.5 billion Lhoist North America acquisition and its financing, given the amended and the step-down in the maximum from 4.75x to 3.75x.
Other Building Materials fell 14% to $34M on higher ready-mix raw material costs and lower paving job margins, even as revenues grew 12%.
from continuing operations attributable to Martin Marietta were $256M ($4.26 per diluted share), down from $292M, including $45M in after-tax acquisition-related and rationalization charges.
from continuing operations dropped to $406M from $525M, largely due to higher income tax payments tied to the QUIKRETE transaction gain.
The company amended its Revolving Facility to accommodate the pending Lhoist North America acquisition, with a maximum stepping from 4.75x down to 3.75x over time.
Quantitative and Qualitative Disclosures About Market Risk
Interest-rate sensitivity in end markets and variable-rate debt, plus energy-cost exposure, are the primary market risks disclosed.
⌄
Construction and steelmaking end markets are highly sensitive to interest rates, and the current remains above inflation, sustaining restrictive monetary policy.
A hypothetical 100-basis-point rise in rates on the $655 million of variable-rate borrowings would increase annual by $7 million.
Pension expense carries interest-rate risk through the and expected return on plan assets, with sensitivity details deferred to the 2025 10-K.
A hypothetical 10% change in energy prices versus 2025 would alter energy expense for continuing operations by $29 million, assuming comparable volumes.
The Specialties business has fixed-price agreements covering a portion of its 2026 energy needs, partially mitigating commodity-price exposure.
Key risks include cyclical construction demand, LNA Transaction execution, weather impacts, and regulatory/competition challenges.
⌄
Demand for aggregates is cyclical and sensitive to interest rates, inflation, and public infrastructure funding, with 58% of 2025 shipments tied to nonresidential and residential markets.
The pending $13.5 billion LNA Transaction introduces material execution risks including integration challenges, substantial new debt, shareholder , and potential failure to close.
Adverse weather, particularly hurricanes, storms, and droughts, can significantly disrupt production, shipments, and demand, with operations in coastal and drought-prone areas most exposed.
Securing and permitting quality aggregates reserves near growing markets is increasingly difficult due to competing land uses and community opposition, threatening long-term growth.
Climate change regulations and GHG emission limits could increase operating costs, especially for the Specialties business's lime and magnesia plants, with no commercially proven carbon capture technology at scale.
Labor disputes pose a risk, with collective bargaining agreements covering 59% of Specialties hourly employees expiring between 2027 and 2030.
