Martin Marietta Materials reported Q2 2026 revenues of $1,947 million, up from $1,609 million a year earlier. Earnings from continuing operations were $256 million versus $292 million in Q2 2025, with diluted EPS from continuing operations of $4.26 compared with $4.84. A February 2026 divestiture of its Midlothian cement plant and related Texas ready-mix operations generated an after-tax gain of $1.4 billion, driving year-to-date net earnings attributable to Martin Marietta to $1,764 million, up from $444 million, and total diluted EPS to $29.27.
Operating cash flow for the first half of 2026 was $339 million, down from $605 million, reflecting a large noncash gain on divestitures and working-capital movements. Total assets rose to $21,305 million, while total debt increased to $5,951 million, including greater use of the Trade Receivable Facility. The company closed a major asset exchange with QUIKRETE, acquired New Frontier Materials, and agreed to acquire Lhoist North America for $13.5 billion (including $7.0 billion in cash and 10,953,543 new shares), subject to approvals, which is expected to further expand its aggregates and industrial minerals footprint.
Martin Marietta Materials reported record second‑quarter 2026 revenues of $1.947 billion, up 21% from 2025, and record Adjusted EBITDA from continuing operations of $638 million, up 13%. Adjusted diluted EPS from continuing operations rose to $5.00, while GAAP diluted EPS from continuing operations was $4.26.
Aggregates shipments reached 61.6 million tons, up 17%, with lower reported average selling prices reflecting acquisition mix. The Specialties business posted record quarterly revenues of $152 million and gross profit of $50 million. Management raised full‑year 2026 revenue guidance to $7.2–$7.4 billion and reaffirmed Adjusted EBITDA guidance of $2.36–$2.50 billion.
The company agreed to a roughly $13.5 billion cash‑and‑stock combination with Lhoist North America and completed the New Frontier Materials acquisition, expanding aggregates and Specialties. An enterprise review identified about $350 million of expected annualized cash flow improvements; year‑to‑date, more than $200 million of cash has been unlocked versus the prior‑year period.
Martin Marietta Materials, Inc. entered into Amendment No. 1 to its $800,000,000 five-year senior unsecured revolving credit facility with JPMorgan Chase Bank, N.A., modifying the financial covenant so that, if its acquisition of Lhoist North America, Inc. is consummated, the maximum permitted Leverage Ratio is 4.75:1.00 for the first three fiscal quarters after closing, 4.25:1.00 for the next three fiscal quarters, and 3.75:1.00 thereafter.
The company also entered into a new Term Credit Agreement providing a three-year senior unsecured term loan facility of $1,500,000,000, subject to completion of the acquisition and customary conditions. Proceeds may be used to pay a portion of the cash consideration and related fees and expenses. The term loans will bear interest at either a Term SOFR Rate or Base Rate plus a ratings-based margin and carry a commitment fee on undrawn commitments from October 25, 2026 until termination. The agreement includes a leverage covenant with the same 4.75:1.00, 4.25:1.00 and 3.75:1.00 thresholds, an option to exclude certain acquisition debt for four quarters if the unadjusted ratio does not exceed 4.25:1.00, and a provision allowing up to $500,000,000 of cash and cash equivalents to reduce consolidated debt when both the revolving facility and the accounts receivable securitization facility are undrawn.
Martin Marietta Materials agreed to acquire Lhoist North America from LNA Holding for $13.5 billion, paid with $7 billion in cash and 10,953,543 newly issued shares valued at $6.5 billion. The deal is subject to antitrust clearance and other customary closing conditions, with an outside date that can extend into mid-2027.
LNA Holding is expected to own about 15% of Martin Marietta’s stock after closing and will receive board representation plus a non-voting observer, subject to ownership thresholds and voting support for board nominees. The seller’s shares are locked up for two years in stages.
Martin Marietta secured a 364-day unsecured bridge loan commitment of up to $7.0 billion to fund the cash portion. If required regulatory approvals are not obtained by the extended outside date, Martin Marietta may owe a $350 million cash termination fee to LNA Holding.
Martin Marietta Materials plans a $13.5 billion combination with Lhoist North America, agreeing to acquire all of Lhoist North America’s equity for $7.0 billion in cash and $6.5 billion in Martin Marietta common stock. The deal values LNA at about 15x its 2025 Adjusted EBITDA, including run-rate cost synergies.
LNA generated $1.8 billion of gross revenues and $786 million of Adjusted EBITDA in 2025, a 45% margin, supported by more than 2 billion tons of limestone reserves with over 200 years of useful life. Martin Marietta expects the transaction, targeted to close in the second half of 2026 subject to regulatory approvals, to be accretive to earnings and margins in the first 12 months after closing, with about $85 million of annual run-rate cost synergies within two years. Combined Net Leverage is projected at 3.7x at closing, with a goal of reducing it below 2.5x within 24 months. On closing, the Berghmans family is expected to own roughly 15% of Martin Marietta and gain rights to appoint one director and one board observer.
