Martin Marietta posts record Q3 revenue, raises 2026 guidance after $12.9 bn Lhoist acquisition

Martin Marietta Materials reported third‑quarter 2026 revenue of $2.37 billion, a 28% year‑over‑year increase, while net earnings fell to $256 million ($3.94 per share) and adjusted earnings were $5.47 per share. The results reflect the recent $12.9 billion purchase of Lhoist North America, which contributed $216 million of revenue and $115 million of cash gross profit in the quarter. The company lifted its full‑year 2026 revenue midpoint to $7.8 billion and its adjusted EBITDA midpoint to $2.48 billion.

The revenue beat and higher guidance suggest stronger top‑line momentum from the Lhoist deal, which may support the stock’s recent price rise. The updated 2026 adjusted EBITDA midpoint of $2.48 billion sets a new profitability target for investors, as disclosed in the company’s release.
