Lhoist and Martin Marietta have signed a definitive agreement to combine Lhoist North America with Martin Marietta, creating a larger North American aggregates, calcium-based products, and building materials business while strengthening both companies’ long-term growth strategies.
Lhoist and Martin Marietta Materials have announced a definitive agreement to combine Lhoist North America with Martin Marietta in a move designed to strengthen their position across North America’s aggregates, lime, and building materials sectors.
The transaction will bring together complementary mining and processing assets, while enabling both organizations to expand customer capabilities, improve operational scale, and support long-term value creation.
Under the agreement, Financière de Gestions Internationales (FGI), the Berghmans family holding company, will become Martin Marietta’s largest single shareholder and will receive representation on the company’s Board of Directors.
The ownership position reflects FGI’s confidence in the combined company’s long-term growth strategy and its commitment to supporting sustainable value creation.
The transaction will also leave Lhoist’s operations in Europe, Latin America, Asia-Pacific (APAC), and the Middle East and North Africa (MENA) fully owned by FGI.
The combined business is expected to benefit from complementary assets, broader capabilities, and increased opportunities for customers, employees, and shareholders.
Following completion of the transaction, Lhoist said it will continue sharpening its strategy across its remaining global operations, with a focus on growing its lime business while accelerating its ambitions in minerals and aggregates.
Baron Berghmans, Chairman of Lhoist Group, said: “This combination is a milestone in our Group’s history. By uniting Lhoist North America with Martin Marietta, we establish a long-term partnership with one of North America’s premier building materials companies and create an opportunity to participate in the future growth of the combined business. At the same time, our ambition and commitment to our businesses in Europe, Latin America, and APAC & MENA is unwavering. I wish to thank our teams for their professionalism and dedication, which have been instrumental throughout this process”
Philipp Niemann, CEO of Lhoist Group, said the transaction aligns with the company’s long-term strategy.
“Combining with Martin Marietta, a leading North American building materials company, creates a stronger platform for long-term growth and customer service. This transaction strengthens both organizations and is fully aligned with Lhoist’s strategic framework. I am grateful to our teams for their professionalism and dedication throughout this process.”
Following completion of the transaction, Niemann is expected to join Martin Marietta’s Board of Directors.
The transaction remains subject to customary closing conditions, including regulatory approvals.
