Technip Energies has completed its acquisition of Ecovyst’s Advanced Materials & Catalysts (AM&C) business, adding a specialty catalysts and advanced materials platform that the company says will expand its capabilities in advanced catalysts and support growth in sustainable fuels, circular chemistry, and carbon capture.
Following the close, AM&C will continue to operate under its existing leadership team, supported by dedicated R&D, manufacturing, and commercial teams across three facilities in the U.S. and Europe. Technip Energies said 330 employees are joining the company as part of the transaction.
The acquired portfolio includes Advanced Silicas, which supplies specialty silica-based materials and catalysts, and Zeolyst International, a joint venture with Shell Catalysts & Technologies focused on custom zeolite-based materials and catalysts for applications including hydrocracking, sustainable fuels, and advanced recycling.
Technip Energies said AM&C brings more than 40 years of proven expertise and is expected to be immediately accretive to earnings and cash flow. The company framed the acquisition as a way to combine AM&C’s catalysts and materials platform with its own process technologies and engineering expertise, creating a more integrated offering to help customers improve efficiency, reliability, and emissions performance.
For Ecovyst, the sale represents a significant portfolio step. The company previously said it expects net proceeds after taxes and transaction expenses of approximately $530 million and disclosed that it used $465 million of proceeds at closing to pay down its term loan, targeting a net debt leverage ratio below 1.5x.
Support: Evercore served as financial advisor to Technip Energies, with Gibson Dunn as legal counsel and EY-Parthenon as accounting and tax advisor in connection with the transaction. Ecovyst said Lazard Frères & Co. served as its financial advisor.
