Martin Marietta Materials (MLM) completed its merger with Lhoist North America on August 21, a transaction that added over 2 billion tons of high-quality limestone reserves and made it the leading producer of limestone products in the U.S. The company anticipates needing 24 months post-merger to restore its balance sheet to its target investment-grade range. Management has raised its full-year revenue guidance to $7.2 billion-$7.4 billion, but this guidance does not yet include the contribution from the Lhoist North America transaction; investors should await the Q3 earnings update for further details.
