Description of the Company and Basis of Presentation | Description of the Company and Basis of Presentation Description of the Company Celanese Corporation and its subsidiaries (collectively, the "Company") is a global chemical and specialty materials company. The Company produces high performance engineered polymers that are used in a variety of high-value applications, as well as acetyl products, which are intermediate chemicals for nearly all major industries. The Company also engineers and manufactures a wide variety of products essential to everyday living. The Company's broad product portfolio serves a diverse set of end-use applications including automotive, chemical additives, construction, consumer and industrial adhesives, medical, consumer electronics, energy storage, filtration, paints and coatings, paper and packaging, industrial applications and textiles. Definitions In this Quarterly Report on Form 10-Q ("Quarterly Report"), the term "Celanese" refers to Celanese Corporation, a Delaware corporation, and not its subsidiaries. The term "Celanese U.S." refers to the Company's subsidiary, Celanese US Holdings LLC, a Delaware limited liability company, and not its subsidiaries. Basis of Presentation The unaudited interim consolidated financial statements for the three and nine months ended September 30, 2025 and 2024 contained in this Quarterly Report were prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") for all periods presented and include the accounts of the Company, its majority owned subsidiaries over which the Company exercises control and, when applicable, variable interest entities in which the Company is the primary beneficiary. The unaudited interim consolidated financial statements and other financial information included in this Quarterly Report, unless otherwise specified, have been presented to separately show the effects of discontinued operations. In the opinion of management, the accompanying unaudited consolidated balance sheets and related unaudited interim consolidated statements of operations, comprehensive income (loss), cash flows and equity include all adjustments, consisting only of normal recurring items necessary for their fair presentation in conformity with U.S. GAAP. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted in accordance with rules and regulations of the Securities and Exchange Commission ("SEC"). These unaudited interim consolidated financial statements should be read in conjunction with the Company's consolidated financial statements as of and for the year ended December 31, 2024, filed on February 21, 2025 with the SEC as part of the Company's Annual Report on Form 10-K. Operating results for the three and nine months ended September 30, 2025 are not necessarily indicative of the results to be expected for the entire year. In the ordinary course of business, the Company enters into contracts and agreements relative to a number of topics, including acquisitions, dispositions, joint ventures, supply agreements, product sales and other arrangements. The Company endeavors to describe those contracts or agreements that are material to its business, results of operations or financial position. The Company may also describe some arrangements that are not material but in which the Company believes investors may have an interest or which may have been included in a Form 8-K filing. Investors should not assume the Company has described all contracts and agreements relative to the Company's business in this Quarterly Report. For those consolidated ventures in which the Company owns or is exposed to less than 100% of the economics, the outside shareholders' interests are shown as noncontrolling interests. Immaterial Revision of Prior Period Financial Statements During the nine months ended September 30, 2025, the Company identified immaterial errors in the estimate of the rebates accrual for certain distributors included in Customer rebates (Note 6) and prepaid insurance included in Current Other assets, respectively. The Company evaluated the errors, both quantitatively and qualitatively, and concluded that the impact of these errors is not material to any previously issued annual or interim consolidated financial statements for the impacted periods and is not material to the current periods if left uncorrected; however, to promote the consistency and comparability of the financial statements, the Company has voluntarily revised previously reported financial information. The Company corrected these errors in the accompanying consolidated balance sheet as of December 31, 2024, decreasing Retained earnings by $46 million, increasing Total liabilities by $27 million and decreasing Total assets by $19 million. Impacts to the line items in the consolidated statements of operations for each of the three and nine months ended September 30, 2024 and the years ended December 31, 2024, 2023, 2022 and 2021 did not exceed $14 million. Estimates and Assumptions The preparation of unaudited interim consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the unaudited interim consolidated financial statements and the reported amounts of net sales, expenses and allocated charges during the reporting period. Significant estimates pertain to impairments of goodwill, intangible assets and other long-lived assets, purchase price allocations, restructuring costs and other (charges) gains, net, income taxes, pension and other postretirement benefits, asset retirement obligations, environmental liabilities and loss contingencies, among others. Actual results could differ from those estimates.
