Item 2.05			Costs Associated with Exit or Disposal Activities.

On October 28, 2025, Celanese Corporation (“Celanese” or the “Company”) announced the intended closure of its facility in Lanaken, Belgium to help streamline the Company’s production costs across its global network. Celanese’s facility in Lanaken, Belgium is an acetate tow production site. This proposed cessation is subject to a consultation process with the applicable works council and union representatives at the facility, which the Company intends to initiate on or about October 31, 2025. The Company intends to permanently cease all manufacturing operations during the second half of 2026, subject to the completion of such consultation process.

As a result of this intended closure, the Company expects to record expenses, excluding employee termination costs, of approximately $70 – 90 million, consisting primarily of approximately $55 – 65 million of non-cash accelerated depreciation of fixed asset costs and approximately $15 – 25 million of other facility-related shutdown cash costs, with such cash outflows expected to occur during fiscal years 2026 through 2028.

In addition to these expenses, the Company expects to incur employee termination costs, which are subject to the above-referenced works council consultation. Until such consultation is concluded, the Company is unable to reasonably estimate the employee termination costs it will incur in connection with the intended actions. The Company will disclose the amount, type and timing of such costs promptly after they are determined.

The above charges are estimates; the actual charges may vary significantly based on various factors, including the outcome of the consultation process with the applicable works council and union representatives.
