May 04, 2026 [Chemical Engineering]- INEOS Enterprises has agreed to sell its shares in INEOS Calabrian, its ultra-pure sulfur dioxide and derivatives business, to Ecovyst Inc. (Malvern, Pa.).  INEOS Calabrian operates manufacturing sites in Port Neches, Texas, USA and Timmins, Ontario, Canada. Completion is expected by the end of June 2026.  Until completion, INEOS Enterprises will continue to operate the business as usual, with no change to customer or supplier arrangements.

Ashley Reed, Chairman of INEOS Enterprises, said:  “INEOS Calabrian has been part of INEOS Enterprises for the past ten years, during which time it has delivered significant improvements in safety, operational performance and financial results. This transaction, valued at $190 million, reflects our disciplined approach to portfolio management – acquiring businesses, improving them at pace, and realising value.

“Calabrian is a strong, well-positioned semi-speciality chemicals business. However, it is not a core fit within INEOS’ long-term portfolio. Ecovyst is well placed to take the business forward and support its next phase of growth.”
