Ward Nye, Chair, President and CEO of Martin Marietta, stated, “Martin Marietta delivered record quarterly revenues of $2.37 billion and Adjusted EBITDA from continuing operations of $808 million, representing increases of 28% and 21%, respectively, over the prior year third quarter, as strong performance from recent acquisitions more than offset the effects of expanding inflationary pressures and a dynamic macroeconomic environment.

"The third quarter marked a defining milestone in Martin Marietta's portfolio transformation with the completion of our combination with Lhoist North America (LNA) on August 21. This transaction meaningfully scales our differentiated upstream Specialties platform, establishing Martin Marietta as the nation's leading producer of lime and limestone solutions and broadening our participation across steel, environmental, infrastructure and industrial end markets. Since the closing date, LNA delivered revenues, gross profit and cash gross profit1 of $216 million, $51 million and $115 million, respectively, providing early validation of the strategic and financial merits of the higher-quality, more resilient and diversified portfolio we have intentionally built.

With the closing of LNA, we have updated the midpoints of our full-year 2026 Revenue and Adjusted EBITDA guidance to $7.80 billion and $2.48 billion, respectively, as acquisition contributions are anticipated to more than offset lower near-term expectations for our heritage operations. In 2027, we expect mid- to high-single digit aggregates pricing on a mix-adjusted basis, supported by January 1 pricing actions designed to address inflationary cost pressures. Acquired operations, which currently have selling prices below the Company average, provide meaningful opportunity for continued pricing growth. From an end market perspective, we currently expect continued strength in infrastructure and data centers with softer interest rate-sensitive private construction markets."

Mr. Nye concluded, "As we integrate this year’s acquisitions, we remain focused on safety, commercial and operational excellence, and disciplined execution of the matters within our control. Martin Marietta has a proven playbook for responding decisively to changing market conditions, managing inflationary pressures, protecting profitab

Ward Nye, Chair, President and CEO of Martin Marietta, stated, “Building on our positive trends entering 2026, Martin Marietta delivered record second-quarter revenues and Adjusted EBITDA from continuing operations. Revenues increased 21% and Adjusted EBITDA from continuing operations grew 13%, driven by strong organic performance and acquisition contributions. Infrastructure and heavy nonresidential construction activity across much of our footprint supported favorable shipment trends and underscored the earnings power and resilience of our business model. Most importantly, our team delivered the safest first half in the Company's history, as measured by Total Injury Incident and Lost-Time Incident Rates. Based on our strong first-half results and continued momentum, we are raising our full-year revenue guidance to a range of $7.2 billion to $7.4 billion and reaffirming our full-year Adjusted EBITDA from continuing operations guidance of $2.36 billion to $2.5 billion.

"The quarter was also notable for the announcement of several value creating transactions. Most significantly, and consistent with our strategic plan, on June 27, we entered into a definitive agreement to combine with Lhoist North America (LNA), the nation's leading producer of high-calcium lime, dolomitic lime and industrial mineral products. The planned combination advances our SOAR 2030 objective to expand our differentiated upstream Specialties platform, broadens our participation across infrastructure, manufacturing and industrial end markets and leverages our core quarrying and mineral resource management expertise. The transaction also establishes Martin Marietta as the nation's leading producer of limestone products and further enhances our portfolio of scarce, long-lived reserves. As the transaction has not yet closed, our revised 2026 guidance does not include any contribution from LNA.

"Additionally, on May 15 we completed the acquisition of New Frontier Materials (NFM), expanding our leading aggregates platform along the I-70 corridor. Together, these transactions further strengthen our portfolio by deepening our leadership position in aggregates while accelerating the planned expansion of our differentiated upstream Specialties platform.

"Beyond these portfolio actions, our expanded enterprise review identified opportunities that are expected to generate approximately $350 million of annualized cash flow improvements as we optimize our evolving asset base, network footprint, and sustaining capital requirements. Through disciplined inventory management and reductions in capital spending, we have unlocked more than $200 million of cash year-to-date compared with the prior-year period. Combined with our strong second-quarter organic cost performance, these actions reflect meaningful progress toward our efficiency and cash generation objectives."

Mr. Nye concluded, "Martin Marietta's portfolio today reflects years of disciplined investment and thoughtful portfolio shaping. As we advance our SOAR 2030 objectives, we remain focused on respo

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 item
