Martin Marietta Materials has agreed to acquire Lhoist North America in a transaction valued at $13.5 billion, marking a significant expansion in the building materials sector.
The deal, structured as a combination of cash and stock, positions the Raleigh-based firm to capitalize on rising demand for lime and specialty minerals used in construction and industrial applications.
The acquisition underscores a broader trend of consolidation among major materials producers seeking to diversify beyond traditional aggregates.
By integrating Lhoist’s North American operations, Martin Marietta aims to strengthen its portfolio of high-margin specialty products, which are critical for environmental compliance and infrastructure projects.
The move is expected to enhance the company’s scale and operational efficiency across its existing network.
Market participants are likely to view the transaction as a strategic bet on long-term infrastructure spending and industrial growth.
