Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Background and Basis of Presentation | 1. Background and Basis of Presentation: Description of Business Ecovyst Inc. and subsidiaries (the “Company” or “Ecovyst”), formerly known as PQ Group Holdings Inc. and subsidiaries (“PQ Group Holdings”), is a leading integrated and innovative global provider of specialty catalysts and services. The Company supports customers globally through its strategically located network of manufacturing facilities. The Company believes that its products, which are predominantly inorganic, and services contribute to improving the sustainability of the environment. On December 14, 2020, PQ Group Holdings completed the sale of its Performance Materials business for $650,000, and the results of operations of this business have been presented as discontinued operations in the condensed consolidated financial statements for all periods presented. See Note 3 for more information on the transaction. Effective on August 1, 2021, PQ Group Holdings completed the sale of its Performance Chemicals business for $1,100,000, subject to certain purchase price adjustments as set forth in the agreement. Upon entering into the definitive agreement, the transaction met the held for sale criteria and consequently the financial results of the Performance Chemicals business are reported in discontinued operations in the condensed consolidated financial statements for all periods presented. See Note 3 for more information on the transaction. In connection with the closing of the sale of the Performance Chemicals business, PQ Group Holdings Inc. changed its name from “PQ Group Holdings Inc.” to “Ecovyst Inc.”, changed the ticker symbol of its common stock listed on the New York Stock Exchange from “PQG” to “ECVT” and rebranded PQ Group Holdings segments from “Refining Services” to “Ecoservices” and “Catalysts” to “Catalyst Technologies”. The Company has two uniquely positioned specialty businesses: Ecoservices provides sulfuric acid recycling to the North American refining industry for the production of alkylate and provides on-purpose virgin sulfuric acid for water treatment, mining, and industrial applications; and Catalyst Technologies provides finished silica catalysts and catalyst supports necessary to produce high strength and high stiffness plastics and, through its Zeolyst joint venture, supplies zeolites used for catalysts that remove nitric oxide from diesel engine emissions as well as sulfur from fuels during the refining process. The Company’s regeneration services product group, which is a part of the Company’s Ecoservices segment, 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. The notes to the condensed consolidated financial statements, unless otherwise indicated, are on a continuing operations basis. Basis of Presentation The condensed consolidated financial statements included herein are unaudited. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted pursuant to such rules and regulations for interim reporting. In the opinion of management, all adjustments of a normal and recurring nature necessary to state fairly the financial position and results of operations have been included. The results of operations are not necessarily indicative of the expected results for the full year. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.
