Martin Marietta Materials reported second-quarter 2026 results with record revenues of $1.947 billion, a 21% increase year-over-year, driven by strong organic performance and acquisition contributions. Adjusted EBITDA rose 13% to $638 million, while diluted earnings per share declined 12% to $4.26 due to a $52 million non-cash charge from acquired inventory fair value adjustments. The company raised its full-year 2026 revenue guidance to $7.2–$7.4 billion and reaffirmed adjusted EBITDA guidance of $2.36–$2.5 billion, citing expected $350 million in annualized cash flow benefits from operational efficiencies. Additionally, Martin Marietta announced a definitive agreement to combine with Lhoist North America in an approximately $13.5 billion transaction and completed the acquisition of New Frontier Materials.
