• Sustained pricing momentum and effective cost management continue to yield strong results across the aggregates business.
• Magnesia Specialties business achieved record quarterly revenues and second-quarter records for gross profit and gross margin.
• The first six months of 2025 represented the lowest total reportable incident rate in company history, indicating strong safety performance.
• Increased full-year 2025 Adjusted EBITDA guidance to $2.30 billion at the midpoint, reflecting confidence in future performance.

Negatives

• Aggregates shipments decreased 0.6% to 52.7 million tons, impacted by softening demand in Colorado and wet weather.
• Cement and ready mixed concrete revenues decreased 6% to $245 million, with gross profit down 25% to $54 million due to lower shipments and higher ready mix raw material costs.
• Asphalt and paving revenues decreased 7% to $228 million, and gross profit decreased 8% to $33 million due to lower shipments and higher costs.
• Residential construction demand is expected to remain subdued until affordability headwinds improve.

Risks

• Potential for shipment declines resulting from economic and weather events beyond the company's control.
• Risk of a widespread decline in aggregates pricing, including a decline in aggregates shipment volume negatively affecting aggregates price.
• Cement and ready mixed concrete sales are subject to significant changes in supply, demand, and price fluctuations.
• Uncertainty regarding the level and timing of federal, state, or local transportation or infrastructure or public projects funding.
• Sustained high mortgage interest rates and other factors could lead to a slowdown in private construction.
• Unfavorable weather conditions (e.g., storms, wildfires, extreme temperatures) can significantly affect production schedules, volumes, and profitability.
• Volatility of fuel and energy costs, particularly diesel fuel, electricity, and natural gas, impacting operational costs.
• Risks associated with construction labor shortages and/or supply chain challenges.
• Labor relations risks, including unionization efforts, work stoppages, or strikes.
• Difficulty recruiting and retaining skilled employees, particularly for physically demanding roles in rural or less-populated markets.
• Unexpected equipment failures, unscheduled maintenance, industrial accidents, or other prolonged disruptions to production facilities.
• Potential negative impacts of disease outbreaks, epidemics, or pandemics on suppliers, customers, or employees.
• Future implementation of emissions-based taxes or carbon-pricing schemes could materially increase cement operating costs or restrict production capacity.
• Difficulty in securing timely land use approvals or environmental permits for development or expansion.
• Increased transportation costs, including from higher or fluctuating passed-through energy costs or fuel surcharges.
• Potential impact on costs, supply chain, and oil and gas prices due to geopolitical conflicts.
• Risks associated with third-party technology vendors, including exposure to cybersecurity vulnerabilities or service outages.
• Inflation and its effect on both production and interest costs.
• The possibility that expected synergies from acquisitions will not be realized or will not be realized within the expected time period.
• Risks related to executive succession planning, retention, and development of leadership talent.

Future Outlook

The company expects infrastructure activity to remain robust due to sustained federal and state investment. Nonresidential demand is anticipated to benefit from accelerating data center development and a warehouse recovery, partially offsetting softness in interest rate-sensitive light commercial construction. Residential construction demand is projected to remain subdued until affordability headwinds improve. Full-year 2025 Adjusted EBITDA guidance has been raised to a midpoint of $2.30 billion, reflecting strong first-half performance and contributions from recent acquisitions. The asset exchange with Quikrete is expected to close in the first quarter of 2026, further optimizing the portfolio for a more durable and resilient earnings profile.

Management Comments

• "Our Company’s second-quarter performance is a testament to the value-added benefits of our geography and durable products. As a result, we established record quarterly aggregates revenues and second-quarter records for aggregates profitability, Adjusted EBITDA and Adjusted EBITDA margin, as sustained pricing momentum and effective cost management continue to yield strong results."
• "Additionally, our Magnesia Specialties business achieved record quarterly revenues and second-quarter records for gross profit and gross margin."
• "Given our strong first-half performance, together with acquisition contributions and current shipment trends, we are increasing our full-year 2025 Adjusted EBITDA guidance to $2.30 billion at the midpoint."
• "Demand across our primary end markets remains varied. Infrastructure activity remains robust, underpinned by sustained record levels of federal and state investment."
• "In nonresidential, accelerating data center development and a warehouse recovery are contributing positively to near-term demand, partially offsetting relative softness in interest rate-sensitive light commercial construction."
• "We expect residential construction demand to remain subdued until ongoing affordability headwinds improve."
• "Martin Marietta's resilient aggregates-led building materials business in economically and structurally advantaged markets, together with our highly complementary Magnesia Specialties business, provides enduring earnings strength through periods of demand cyclicality."

Industry Context

The company's performance reflects broader trends in the U.S. construction and materials industry. Robust infrastructure spending, driven by federal and state investments, continues to be a strong tailwind. The nonresidential sector shows a mixed picture, with strong demand from data center development and warehouse recovery counteracting weakness in interest rate-sensitive light commercial projects. The residential construction market remains challenged by affordability issues, consistent with broader housing market trends. The strategic acquisitions and divestitures indicate a focus on optimizing the portfolio towards higher-margin, aggregates-led businesses, a common strategy among large materials companies seeking to enhance resilience through economic cycles.

Stakeholder Impact

• Shareholders: Positive impact through increased earnings, share repurchases, and dividends, indicating strong shareholder value creation.
• Employees: Positive impact through a focus on safety, achieving the lowest total reportable incident rate in company history.
• Customers: Continued supply of essential building materials, with pricing adjustments reflecting market conditions.
• Creditors: Maintained balance sheet flexibility with $1.2 billion of unused borrowing capacity, supporting financial stability.

Next Steps

• Host an online web simulcast of the second quarter 2025 earnings conference call on Thursday, August 7, 2025, at 10:00 a.m. Eastern Time.
• An online replay of the conference call will be available approximately two hours following the live broadcast and will continue for one year.
• The Divestiture Assets (Midlothian cement plant, related cement terminals, and North Texas ready-mixed concrete assets) will be classified as discontinued operations beginning with the third quarter of 2025.
• The asset exchange transaction with Quikrete Holdings, Inc. is expected to close in the first quarter of 2026, subject to regulatory approvals and other customary closing conditions.

Key Dates

Despite some varied demand in end markets, the company's strong financial health, cash generation, and proactive strategic moves make it a compelling investment.
