With the acquisition complete, HarbisonWalker is being combined with another Platinum acquisition, the high-temperature solutions business of Imerys SA. That business is now operating as Calderys. 

The HarbisonWalker brand will survive the acquisition, and Pittsburgh, Pa., will serve as the headquarters for the combined company’s Americas regions. However, Calderys president and chief executive Michel Cornelissen will serve as the global CEO of the combined company. His expanded role begins immediately. 

“We have a tremendous opportunity to bring together the best of both companies to create a high-growth, customer-centric refractories solutions provider with global scale,” said Cornelissen. “Our goal is to be the best partner for our customers anywhere in the world, to support them in their energy transition needs, and to set a new benchmark for the industry.”

Platinum Equity said it will seek additional opportunities to help the combined company grow.

“Joining forces will create additional scale and provide both businesses access to new technologies, increasing the value proposition for customers,” said Platinum Equity managing director Malik Vorderwuelbecke. “It will also create a global platform with new opportunities for growth, both organically and through additional acquisitions in key product areas and geographies.”
