Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On March 14, 2025, the Board of Directors of Celanese Corporation (the “Company”) adopted and approved an amendment (the “Amendment”) to Article VIII, Section 8.01 of the Company’s Seventh Amended and Restated By-laws (as amended, the “Amended By-laws”), effective immediately. The Amended By-laws provide that, to the fullest extent permitted by law, the federal district courts of the United States of America shall be the sole and exclusive forum for any claim arising under the Securities Act of 1933 or any rule or regulation promulgated thereunder, in each case, as amended from time to time. If the foregoing provision or its application to any person or any circumstance is illegal, invalid or unenforceable, the sole and exclusive state court forum for any such claim will be the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, another state court located within the State of Delaware).

The foregoing description of the Amendment is qualified in its entirety by reference to the full text of the Amendment, which is attached hereto as Exhibit 3.1 and incorporated herein by reference.
