In a move which will strengthen its position in the lime and industrial minerals sector, Martin Marietta Materials Inc has announced it is to acquire Lhoist North America in a cash-and-stock deal valued at around $13.5bn.
According to Martin Marietta, the company expects to use a mix of $7bn in cash along with shares of its stock valued at $6.5bn to fund the deal, which is expected to be completed in the second half of 2026, subject to regulatory approvals.
Upon closing, the Berghmans family, the current owner of Lhoist, is expected to own approximately 15 percent of Martin Marietta on a fully diluted basis and will have the right to appoint one director and one observer to the comapny’s board of directors.
Martin Marietta expects its combined net leverage ratio to be approximately 3.7x at closing with a target of reducing this ratio to below 2.5x within 24 months of closing through strong free cash flow generation. Upon closure, the company expects to realise about $85m in annual run-rate cost synergies.
Lhoist operates a network of 20 quarries and production facilities and 45 distribution terminals, generating $1.8bn in gross sales and $786m of adjusted earnings before interest, taxes, depreciation and amortisation (EBITDA) for the 12 months ended 31 December 2025. The company has over 2 billion tonnes of high-quality limestone reserves positioned in high-growth, Sun Belt metropolitan corridors. This reserve base of over 200 years of useful life represents one of the most significant and strategically advantaged limestone positions in North America.
“This transaction represents another transformational milestone for Martin Marietta and directly advances our SOAR 2030 objective to expand our complementary, upstream Specialties segment in lime and other industrial minerals,” said Ward Nye, chair, president and chief executive of Martin Marietta. “It builds on our core quarrying competency, expands our geographic footprint and immediately establishes Martin Marietta as the leading national producer of lime solutions. As the United States continues to invest in infrastructure, advanced manufacturing, energy development and industrial expansion, demand for high-quality lime products is expected to remain resilient for decades to come.
“With long-lived limestone reserves, a complementary distribution network, and an attractive financial profile, the LNA business strengthens our portfolio, enhances our ability to serve both new and existing customers, and deepens our role in providing the critical materials necessary to build our nation’s infrastructure, manufacturing and industrial base. Importantly, it reinforces our ability to deliver consistent, through-cycle performance and long-term value creation,” he added.
“For more than a century, our family has built Lhoist into a global leader by safeguarding world-class limestone reserves and serving our customers with discipline, quality and care,” said Baron Berghmans, chairman of Lhoist Group. “In Martin Marietta, we have found a partner who shares these values, honors the legacy we have carefully built and ensures it will endure for generations to come.”
