Description of Business
Ecovyst Inc. and subsidiaries (the “Company” or “Ecovyst”) is a leading provider of virgin and regenerated sulfuric acid products and services. The Company supports customers through its strategically located network of manufacturing facilities. The Company believes that its products and services contribute to improving the sustainability of the environment.
The Company has a uniquely positioned specialty business, Ecoservices, which provides sulfuric acid recycling to the North American refining industry for the production of alkylate and provides high quality and high strength virgin sulfuric acid for mining and industrial applications. Ecoservices also provides chemical waste handling and treatment services, as well as ex-situ catalyst activation services for the refining and petrochemical industry.
The Company’s regeneration services product group typically experiences seasonal fluctuations as a result of higher demand for gasoline products in the summer months and lower demand in the winter months. These demand fluctuations result in higher sales and working capital requirements in the second and third quarters.
