Date of closing

June 2017
Imerys has agreed to acquire Kerneos from Astorg.

Less than two years after S&B’s acquisition, Imerys takes a further step in its development strategy with the acquisition of Kerneos. With this operation, the Group would again enhance its specialty offering in high-potential markets and improve its growth and profitability profile while creating value.

Thanks to its expertise in calcium aluminate technologies, Kerneos develops performance binders that contribute key properties (rapid hardening, self-leveling, sealing and wear, corrosion or heat resistance), to its customers’ innovating solutions for construction (screed and adhesive tiles mortars, etc.), civil engineering (sewage system infrastructure, etc.) or refractories (protection of blast furnaces, thermal power plant, etc.) sectors.

With an access to quality mining reserves and resources, a global sales network, 9 high-performance production sites in 5 countries and great innovation capability, Kerneos fits perfectly with Imerys’ business model and has a sound history of growth and profitability.

Finally, the acquisition project of Kerneos, would be in full compliance with Imerys’ external growth criteria. It would have a positive impact on net income from current operations per share from the first year of consolidation and would rapidly create value thanks notably to synergies estimated at €23m. The transaction, entirely funded by the Group’s available resources, would maintain Imerys’ financial soundness and complies with its goal of keeping an investment grade credit rating.


  • Strengthen Imerys growth and profitability profile by integrating performing assets
  • Enhance Imerys specialty minerals offering for industries in high-potential markets
  • Benefit from operational, product development and financial synergies estimated at €23m
