Ecovyst to Sell Advanced Materials & Catalyst Business to Technip Energies

WAYNE, Pa. – September 11, 2025 – Ecovyst Inc. (NYSE: ECVT), a global provider of advanced materials, specialty catalysts, virgin sulfuric acid, and sulfuric acid regeneration services, has announced a definitive agreement to sell its Advanced Materials & Catalysts segment to Technip Energies, a global technology and engineering firm, for $556 million.

The deal, which values the segment at 9.8 times its adjusted EBITDA for the year ending December 31, 2024, signals a strategic shift for Ecovyst as it seeks to streamline operations and capitalize on growth opportunities in its remaining businesses. The sale is subject to regulatory approvals and customary closing conditions, with completion expected in the first quarter of 2026.

Ecovyst CEO Kurt J. Bitting stated, “The Advanced Materials & Catalyst segment is a high-quality business with attractive margins. We determined that the market undervalued the segment, prompting a strategic review. We believe this sale, approved by our Board, will allow us to realize its value for our stockholders.” He added that the transaction represents a “pivotal moment” for Ecovyst. The company anticipates net proceeds of approximately $530 million after taxes and transaction-related expenses.

Following a partial repayment of its Term Loan, Ecovyst expects a Net Debt Leverage Ratio of below 1.5x, bolstering its balance sheet and providing increased financial flexibility. The company plans to allocate capital toward strategic growth initiatives and return capital to shareholders, with approximately $200 million remaining under its existing share repurchase authorization.

Technip Energies’ CEO, Arnaud Pieton, views the acquisition as accretive and aligned with the company’s capital allocation strategy. “The acquisition of Advanced Materials & Catalysts is accretive for Technip Energies and is in line with our disciplined capital allocation strategy to drive long-term value creation. It brings differentiated capabilities in catalyst technologies and advanced materials, enhancing our ability to deliver high-performance, process-critical solutions to our clients,” Pieton said. The acquisition strengthens Technip Energies’ technology portfolio and opens avenues for product development and market expansion. The deal will allow Technip energies to leverage the capabilities of Advanced Materials & Catalysts to develop green chemicals and Biofuels, aligning with their strategy to be a leader in the energy transition.

Analysts note that the divestiture allows Ecovyst to focus on its Ecoservices division, which provides sulfuric acid recycling and virgin sulfuric acid. This segment benefits from a growing demand for alkylate in the North American refining industry and a broader need for high-strength virgin sulfuric acid in industrial and mining applications. Furthermore, the sale of the Advanced Materials & Catalysts segment, while profitable, could potentially reduce Ecovyst’s exposure to the cyclical nature of the petrochemical industry.

For Technip Energies, the acquisition represents a strategic expansion into specialty catalyst technologies. This move will provide a competitive edge in delivering process-critical solutions to clients in the refining, petrochemical, and sustainable chemistry sectors. By integrating Advanced Materials & Catalysts into its portfolio, Technip Energies aims to accelerate innovation and enhance its offerings in the energy transition market.
