Ward Nye, Chair, President and CEO of Martin Marietta, stated, "2026 is off to a strong start, with revenues improving 17% to a new first-quarter record. Organic aggregates shipment growth of 7% meaningfully exceeded expectations, benefiting from an early start to the construction season in the Midwest and Colorado, as well as strong infrastructure and heavy nonresidential demand across our geographic footprint. The quarter's results reflect a 14% improvement in both Adjusted EBITDA from continuing operations and Adjusted earnings per diluted share from continuing operations. Importantly, our teams delivered the best first-quarter safety performance in the Company's history, underscoring our unwavering commitment to world-class safety and operational excellence.

"As noted, on February 23 we closed our largest aggregates acquisition to date through an Internal Revenue Code Section 1031 asset exchange with Quikrete Holdings, Inc. (QUIKRETE). This milestone enhanced the quality and durability of our earnings profile and provided $450 million of cash to redeploy into M&A opportunities. As such, and consistent with the Company's strategic plan, on April 19, we signed a definitive agreement to acquire New Frontier Materials (NFM). NFM is a leading Midwestern aggregates-led producer with high-quality, strategically located reserves complementing Martin Marietta's existing footprint and long-term growth objectives.

"With April's continued strong product demand, the impact of April 1 price increases, and ongoing optimization efforts, we are reaffirming our full-year 2026 Adjusted EBITDA from continuing operations guidance of $2.43 billion at the midpoint."

Mr. Nye concluded, "Our increasingly aggregates-focused portfolio, complemented by a differentiated Specialties business with aggregates-like characteristics, positions us to deliver superior performance across a broad range of economic environments while maintaining discipline through periods of macroeconomic volatility. With SOAR 2030 underway, we remain confident in our ability to achieve our 2026 objectives while creating sustainable long-term value for shareholders."

First-Quarter Financial and Operating Results

(All financial and operating results are for continuing operations and comparisons are versus the prior-year first quarter, unless otherwise noted)

Building Materials Business

Aggregates

First-quarter aggregates shipments increased 12.4 percent to a first-quarter record 43.9 million tons, driven by organic growth and partial-quarter contributions from the operations acquired from QUIKRETE on February 23, 2026. Average selling price (ASP) of $23.70 per ton was in line with the prior-year quarter, reflecting acquisition and geographic mix headwinds, as combined organic shipments increased more than 20 percent in the Central and West Divisions, which typically carry lower ASPs and related gross margins.

Aggregates gross profit decreased $9 million, or 3 percent, to $288 million, inclusive of the $22 million charge for the impact of selling acquired inventory after markup to fair market value as part of purchase accounting and higher depreciation, depletion and amortization expense. Organic cost of goods sold per ton increased 5.6 percent and included approximately 300 basis points of headwinds from higher pass-through external freight costs and other timing-related items.

Other Building Materials

Other Building Materials revenues decreased 5 percent to $116 million. Consistent with historical first-quarter trends, the business posted a gross loss of $16 million due to seasonal winter operational shutdowns in Colorado and Minnesota.

Specialties Business

Specialties delivered revenues of $143 million and gross profit of $45 million, both quarterly records. These results reflected contributions from the 2025 Premier Magnesia, LLC acquisition and organic pricing gains, partially offset by lower organic shipments and higher energy costs, which weighed on input cost trends during the quarter.

Portfolio Optimization

On February 23, 2026, the Company completed the asset exchange with QUIKRETE. Under the terms of the transaction, Martin Marietta acquired aggregates operations producing approximately 20 million tons annually in Virginia, Missouri, Kansas and Vancouver, British Columbia, along with $450 million in cash. In exchange, QUIKRETE acquired the Company's Midlothian cement plant, related cement terminals, Texas ready mixed concrete plants and certain nonoperating land.

On April 19, 2026, the Company entered into a definitive agreement to acquire NFM, a complementary bolt-on aggregates-led business operating in the greater St. Louis metropolitan area that produces over 8 million tons of aggregates annually. The transaction is expected to close in the second half of this year, subject to regulatory approvals and other customary closing conditions.

Discontinued Operations

In connection with the QUIKRETE asset exchange, the Company's Midlothian cement plant, related cement terminals and Texas ready mixed concrete plants were reported as discontinued operations through the transaction close date. Earnings from discontinued operations, net of income tax expense, totaled $1.4 billion and $12 million for the quarters ended March 31, 2026 and 2025, respectively. Earnings for the quarter ended March 31, 2026, included a $1.4 billion after-tax gain on the asset exchange.

Cash Generation, Capital Allocation and Liquidity

Cash provided by operating activities for the three months ended March 31, 2026, was $227 million, a first-quarter record, compared with $218 million for the prior-year period.

Cash paid for property, plant and equipment additions for the three months ended March 31, 2026, was $186 million.

During the three months ended March 31, 2026, the Company returned $251 million to shareholders through dividend payments and share repurchases. As of March 31, 2026, 10.7 million shares remained available under the current repurchase authorization.

As of March 31, 2026, the Company had $273 million of unrestricted cash and cash equivalents on hand and $1.2 billion of unused borrowing capacity on its existing credit facilities, providing substantial financial flexibility to support the execution of a robust M&A pipeline.

Any or all the Company's forward-looking statements herein and in other publications may prove to be incorrect.

First-quarter results and trends described in this release may not necessarily be indicative of the Company's future performance. The Company's outlook is subject to risks and uncertainties and is based on assumptions that the Company believes are reasonable but which may be materially different from actual results. Factors that the Company currently believes could cause actual results to differ materially from the forward-looking statements, including the outlook and 2026 Guidance, include, but are not limited to: the Company's ability to address challenges, including shipment declines caused by economic and weather events beyond its control; a widespread decline in aggregates pricing, including reduced shipment volume negatively affecting price; the termination, capping, reduction or suspension of federal and/or state fuel tax(es) or other revenue related to public construction; the impact of the Administration on the availability and timing of federal and state infrastructure investment; the level and timing of federal, state or local transportation or infrastructure or public projects funding, including any issues arising from such budgets, particularly in Texas, North Carolina, Colorado, California, Georgia, Florida, South Carolina, Arizona, Iowa and Minnesota; the United States Congress' inability to reach agreement internally or with the Executive Branch on policy affecting the federal budget; a prolonged Federal government shutdown; the ability of states or other entities to finance approved projects through tax revenues or alternative financing; construction spending levels in the Company's markets; reductions in defense spending and impacts on construction activity on or near military bases; declines in energy-related construction due to sustained low global oil prices or changes in oil production or capital spending, particularly in Texas; sustained high mortgage interest rates and factors leading to a slowdown in private construction in some areas; unfavorable weather, including storms, hurricanes, wildfires, timing of seasons, drought, rainfall, or extreme temperatures affecting production schedules, shipment volumes, product/geographic mix and profitability; volatility in fuel and energy costs, including diesel, electricity, natural gas and consumables like steel, explosives, tires and conveyor belts, as well as natural gas for the Company's Specialties business;

the performance of the overall United States economy; governmental regulation, including environmental laws and climate change regulations at state and federal levels; implementation of emissions taxes, carbon-pricing schemes, or stricter climate-related rules that could increase operating costs or restrict Specialties production; delays or difficulties in securing timely land use approvals or environmental permits amid changing regulatory expectations; increasing legal actions or public pressure related to environmental impact, emissions, or land use could result in reputational harm or financial liability; failure to meet evolving environmental, social, and governance (ESG) standards or investor benchmarks may affect access to capital or shareholder confidence; changes in external ESG ratings or methodologies could affect investor sentiment or index inclusion; increasing competition for water access or stricter water usage regulations could impact production, especially in drought-prone regions; outcomes of environmental or land-use proceedings, or increased costs associated with regulatory obligations, including site reclamation; elevated premiums or reduced coverage availability for property, casualty, or environmental liability could increase risk exposure; online misinformation campaigns or social media-driven reputational harm could affect stakeholder trust and market perception; transportation availability and investment in rail infrastructure impacting the movement of materials especially to the Company's Texas, Southeast and Gulf Coast markets, the movement of essential dolomitic lime to the Company's Specialties plant in Manistee, Michigan and its customers, and the movement of magnesite from the Company's Specialties' Gabbs, Nevada facility to processing plants in North Carolina, Indiana and Pennsylvania and the Company's customers; increased transportation costs, including increases from energy price fluctuations, fuel surcharges, and compliance with tightening regulations, including water shipments; availability of trucks and licensed drivers for material transport; availability and cost of construction equipment in the United States; weakness in the steel industry markets served by the Company's dolomitic lime products; geopolitical risks affecting costs, supply chain, oil and gas prices, including conflict zones such as Iran, Russia-Ukraine, Israel-Middle East and potential China-Taiwan tensions; trade disputes and tariffs impacting the U.S. economy; unplanned cost changes or customer realignments affecting earnings; dependence on information technology and automated systems; risks related to third-party vendors, including exposure to cybersecurity vulnerabilities or service outages; inflation pressures on production and interest costs; customer concentration in construction markets increasing the risk of potential losses on customer receivables; demand levels, production volumes, and cost management affecting operating leverage and profitability; risks related to acquisitions, including, integration challenges and the possibility that acquisition synergies may not be realized as expected or within anticipated timeframes, potentially impacting profitability and debt covenant compliance; risks related to executive succession, retention and leadership development critical to strategy execution, including impacts from unexpected leadership changes; changes in tax laws or interpretations, including those related to acquisitions or divestitures, which could increase tax rates; violation of the Company's debt covenants in the event of price and/or volume instability; new or revised accounting rules could impact financial reporting, asset valuations, or covenant compliance; challenges in implementing new technologies or automation systems could lead to inefficiencies, cost overruns, or operational disruptions; improper use or reliance on predictive analytics or AI-driven decision-making could result in flawed forecasting, compliance issues, or reputational damage; cybersecurity risks; downward pressure on the Company's common stock price affecting goodwill impairment evaluations; potential credit rating downgrades to non-investment grade; and other risk factors listed from time to time in the Company's SEC filings.

You should also review the risk factors discussed in Martin Marietta's Annual Report on Form 10-K for the year ended December 31, 2025, and other periodic SEC filings.

Non-GAAP Financial Measures

Adjusted earnings per diluted share from continuing operations is a non-GAAP financial measure used by the Company and by investors to evaluate operating performance and enhance comparability across reporting periods. The Company calculates Adjusted earnings per diluted share from continuing operations by excluding the impact of certain items that management believes are not indicative of the Company's underlying performance from period to period, including impacts directly related to acquisition and divestiture activity as well as asset and portfolio rationalization charges. The Company has elected to add back, for purposes of its Adjusted earnings per diluted share from continuing operations calculation, acquisition, divestiture and integration expenses, the impact of selling acquired inventory after its markup to fair value as part of acquisition accounting and the revaluation of deferred tax liabilities, only for transactions with consideration of at least $2.0 billion for the Building Materials business or $200 million for the Specialties business.

Adjusted earnings per diluted share from continuing operations is not defined by accounting principles generally accepted in the United States (GAAP) and, as such, should not be construed as an alternative to earnings per diluted share from continuing operations. For further information on Adjusted earnings per diluted share from continuing operations, refer to the Company's website at www.martinmarietta.com.
