Martin Marietta to combine with Lhoist North America in $13.5 billion deal.

Martin Marietta to combine with Lhoist North America in $13.5 billion deal. By Thomson Reuters Jun 29, 2026 | 6:53 AM June 29 (Reuters) - Building material firm Martin Marietta Materials said on Monday it would merge with limestone supplier Lhoist North America in a cash-and-stock deal worth $13.5 billion, including debt. Shares of the Raleigh, North Carolina-based company were down about 3% in premarket trade. Martin Marietta would use a mix of $7 billion in cash along with shares valued at $6.5 billion to fund the deal, the company said. Lhoist's Berghmans family - which owns the privately held Lhoist Group, a family-owned Belgian industrial company - would own roughly 15% of Martin Marietta upon the deal's close. The deal is expected to be completed in the second half of 2026. (Reporting by Anshuman Tripathy in Bengaluru; Editing by Shailesh Kuber and Devika Syamnath)
