Co Antrim quarry business Kilwaughter Minerals is set to be acquired by French multinational Saint-Gobain.
The Paris-headquartered corporation announced a binding agreement with the company on Monday evening.
Founded in 1939, the privately-owned quarrying and mineral processor employs around 200 people at its 187-acre limestone quarry near Larne.
Subject to Competition and Markets Authority approval, the transaction is expected to close in the first half of 2025.
Saint-Gobain is a global leader in the design and manufacture of solutions for the construction industry and employs 160,000 people across 76 countries globally.
It has a wide-ranging portfolio of lightweight construction solutions for building facades and envelopes.
Known for K Rend, K Systems and Kilwaughter Lime brands, Kilwaughter Minerals generated revenues of around £50 million in the year to April 2024.
Chief executive Gary Wilmot said: “We’re excited with the opportunity to join the Saint-Gobain group and continue Kilwaughter’s ambitious growth journey.
“Kilwaughter has a rich company culture and heritage, and our focus remains on delivering a leading customer experience, underpinned by our trusted brands.
“We look forward to the added synergy that Saint-Gobain will undoubtedly bring and sharing our passion for innovation, quality and excellence.
“We see the alignment of the vision and values between both companies as a strong building block for our teams and customers.”
