Item 1.01

Entry into a Material Definitive Agreement

Revolving Credit Agreement

On August 11, 2025, Celanese Corporation (the “Company”) and its wholly owned subsidiary Celanese US Holdings LLC (“Celanese US”) entered into a Credit Agreement (the “Revolving Credit Agreement”) by and among the Company, Celanese US as borrower, certain subsidiaries of Celanese US from time to time party thereto as borrowers, each lender from time to time party thereto, Bank of America, N.A., as Administrative Agent, a Swing Line Lender and an L/C Issuer and other Swing Line Lenders and L/C Issuers party thereto. Obligations under the Revolving Credit Agreement are guaranteed by the Company, Celanese US (in the case of borrowings by other borrowers) and certain domestic subsidiaries of Celanese US.

The Revolving Credit Agreement provides for a five-year $1.75 billion unsecured revolving credit facility, which is available in U.S. dollars and certain other currencies as provided therein, and which includes a sublimit of $250 million for the issuance of letters of credit (the “Revolving Facility”). The Revolving Facility replaces the Company's existing revolving credit facility under the Credit Agreement dated as of March 18, 2022, by and among the Company, Celanese US, Celanese Europe B.V., a wholly owned subsidiary of the Company, certain subsidiaries of Celanese US from time to time party thereto as borrowers, each lender from time to time party thereto, Bank of America, N.A., as Administrative Agent, a Swing Line Lender and an L/C Issuer and other Swing Line Lenders and L/C Issuers party thereto, which was terminated on August 11, 2025 in connection with the entry into the Revolving Credit Agreement.

Amounts outstanding under the Revolving Credit Agreement accrue interest at an annual rate based on, in the case of U.S. dollar borrowings, Daily Simple SOFR, Term SOFR or a customary base rate, at the borrower’s election, or in the case of foreign currency borrowings, the interest benchmark for such currency provided in the Revolving Credit Agreement, in each case plus a margin of between 1.00% and 2.00% (or between 0.00% and 1.00% in the case of U.S. dollar base rate borrowings), depending on the Company’s senior unsecured debt ratings. Undrawn amounts under the Revolving Credit Agreement are subject to a commitment fee at an annual rate of between 0.09% and 0.35%, depending on the Company’s senior unsecured debt ratings.

The Revolving Credit Agreement contains certain covenants, which, among other things, require the maintenance of a leverage ratio and a fixed charge coverage ratio, limit increases to the Company's dividend until a specified target ratio is met, restrict certain merger transactions and sales of all or substantially all of the assets and limit the amount of liens and subsidiary indebtedness. Upon the occurrence of certain events of default, the Company’s obligations under the Revolving Credit Agreement may be accelerated. Such events of default include payment defaults under the Revolving Credit Agreement, covenant defaults and other customary defaults.

The financial institutions party to the Revolving Credit Agreement have performed and may continue to perform commercial banking and financial services for the Company for which they have received and will continue to receive customary fees.

The foregoing description does not constitute a complete summary of the terms of the Revolving Credit Agreement and is qualified in its entirety by reference to the copy of the Credit Agreement filed as Exhibit 10.1 to this Current Report, which is incorporated herein by reference.

Amendment to Term Loan Credit Agreement

On August 11, 2025, Celanese US entered into a Sixth Amendment to Credit Agreement (the “Amendment to the Term Loan Credit Agreement”), which amends the Term Loan Credit Agreement, dated as of March 18, 2022, by and among the Company, Celanese US, the subsidiaries of the Company party thereto as guarantors, the lenders party thereto and Bank of America, N.A., as Administrative Agent (as amended, restated, supplemented or otherwise modified prior to August 11, 2025, the “Term Loan Credit Agreement”).

The Amendment to the Term Loan Credit Agreement adds a minimum consolidated fixed charge coverage ratio covenant, limits increases to the Company's dividend until reaching a target consolidated leverage ratio and makes certain other modifications.

The foregoing description does not constitute a complete summary of the terms of the Amendment to the Term Loan Credit Agreement and is qualified in its entirety by reference to the copy of the Amendment to the Term Loan Credit Agreement filed as Exhibit 10.2 to this Current Report, which is incorporated herein by reference.
