Celanese Corporation Announces Preliminary Results of its
Modified “Dutch Auction” Tender Offer

Dallas, April 4, 2007 — Celanese Corporation (NYSE: CE) today announced the preliminary results of its modified “Dutch Auction” tender offer, which expired at 5:00 p.m., New York City time, on April 3, 2007.

In accordance with the terms and conditions of the tender offer, and based on the preliminary count by Computershare Trust Company, N.A., the depositary for the tender offer, Celanese, through its wholly owned subsidiary Celanese International Holdings Luxembourg S.à r.l., expects to accept for purchase approximately two million shares of its Series A Common Stock at a purchase price of $30.50 per share, for a total cost of approximately $62 million.

Stockholders who properly tendered shares in the tender offer at or below the purchase price will have all of their tendered common shares purchased, subject to certain limited exceptions.

The number of shares to be purchased and the purchase price per share are preliminary. Final results of the tender offer will be determined subject to confirmation by the depositary of the proper delivery of the shares validly tendered and not withdrawn. The actual number of shares to be purchased and the final purchase price per share will be announced following the completion of the confirmation process. Payment for the shares accepted for purchase will occur promptly thereafter.

The number of shares that the Company expects to purchase in the tender offer represents approximately 1.3 percent of its currently outstanding common stock.

In the tender offer, the company offered to purchase up to 11,279,243 shares of its common stock at a price not less than $28.00 nor greater than $30.50 per share, for a maximum aggregate repurchase price of up to $344 million.

Also, as previously disclosed in the offer, Celanese, acting through its wholly owned subsidiary Celanese International Holdings Luxembourg S.à r.l., separately agreed to purchase shares of common stock from the investment funds associated with The Blackstone Group, L.P. (which currently own approximately 14% of the Company’s outstanding common stock and elected not to participate in the tender offer) such that Blackstone’s percentage ownership interest in the Company would remain substantially unchanged from its interest immediately prior to the tender offer. Based upon the preliminary count of shares tendered in the tender offer, Celanese will purchase through its wholly owned subsidiary, Celanese International Holdings Luxembourg S.à r.l., approximately 329,000 shares from Blackstone, on the eleventh business day following the expiration of the offer. The shares acquired from Blackstone will be purchased at the final purchase price of $30.50 per share determined in the tender offer for a total cost of approximately $10 million.

In total, including shares to be purchased in the tender offer and from Blackstone, the company expects to purchase approximately $72 million of stock, representing approximately 1.5 percent of its currently outstanding common stock, and has not announced any further actions at this time.

The dealer managers for the tender offer are Merrill Lynch & Co. and Deutsche Bank Securities Inc.; the information agent is Georgeson; and the depositary is Computershare Trust Company, N.A.
