Celanese Corporation Reports Strong Third Quarter Results; Outlook for Full Year at Top End of Previous Guidance Range

Third quarter highlights:

	•		Net sales increase 10% from prior year to $1,685 million
	•		Operating profit up 111% to $200 million
	•		Diluted EPS is $0.64, up 146%
	•		Adjusted EPS is $0.79, up 61%
	•		Operating EBITDA increases 28% to $322 million
	•		Net debt decreases to $2,936 million

Dallas, October 31, 2006: Celanese Corporation (NYSE: CE) today reported net sales increased 10% to $1,685 million, compared to the same period last year, on increased volumes and pricing due to continued strong demand. Operating profit more than doubled to $200 million compared to $95 million in the third quarter of last year on stronger volumes, higher margins and lower other charges and adjustments. Improved earnings in specialty businesses, higher pricing, and increased volumes more than offset higher raw material costs.

Adjusted earnings for the quarter were $0.79 per share compared to $0.49 in the same period last year. These results included a $0.03 per share benefit related to a lower than expected adjusted tax rate

of 25%. Operating EBITDA increased 28% to $322 million from $252 million in the prior year period.

“Celanese delivered another strong quarter of earnings performance. Our integrated hybrid business model continued to deliver value to shareholders and demonstrated resiliency during a period of raw material cost volatility,” said David Weidman, president and chief executive officer. “Our Ticona and Acetate Products businesses delivered tremendous year over year improvements as a result of their growth and revitalization strategies.”

Year to Date 2006

Net sales for the first nine months of 2006 were $5 billion, an 11% increase from the same period last year. The improved results were driven by the inclusion of sales from the Acetex acquisition as well as increased volumes and pricing due to continued strong demand. Operating profit rose 38% to $562 million, compared to $406 million in the first nine months of 2005. Operating EBITDA for the first nine months of 2006 increased 17% to $936 million, compared to $802 million in the same period last year. Adjusted earnings per share for the period were $2.23 compared to $1.66 for the first nine months of 2005, an increase of 34%. The company’s strong business performance, increased volumes, and the realized benefits of several restructuring and productivity efforts drove the improved results.

Recent Highlights

	•		Announced agreement to acquire Acetate Products Limited, the cellulose acetate flake, tow and film activities of Corsadi BV. The proposed acquisition, subject to customary regulatory approvals, is consistent with the company’s goal of improving upon its cost effective, highly reliable supply to the global acetate market.
	•		Celanese moved to an independent board of directors with the election of two new independent directors. The board now has a total of 11 directors, including six independent directors.
	•		Effective in the fourth quarter of 2006, the company expects to lower the borrowing costs on its senior credit facility by

reducing the margin over LIBOR from 2.00% to 1.75% on approximately $1.3 billion of the U.S. dollar denominated portion of the Term Loans due to overall leverage ratio improvement.

Third Quarter Segment Overview

Chemical Products

Chemical Products continued to deliver a high level of sustained earnings. Net sales for the quarter increased from $1.1 billion in the prior period to $1.2 billion on higher pricing and continued strong demand. Operating profit rose 68%, from $101 million to $170 million, compared to the same period last year. Higher volumes in all product lines, price increases in both acetyl and acetyl derivative products, and lower other charges more than offset raw material cost increases, primarily in ethylene and propylene. Operating EBITDA increased from $201 million to $234 million compared to the same period last year. Sharply higher operating margins were partially offset by lower dividends from cost investments in the quarter. Dividends from the company’s cost investments were in line with expectations, but were lower than last year due to timing of dividend payments.

Ticona Technical Polymers

Ticona delivered outstanding performance as it grew volumes in key applications for its specialty engineered polymers. Net sales increased 8% to $230 million, compared to the same period last year, as higher volumes of 10% and favorable currency were partly offset by lower pricing associated with product mix. Volumes increased in all product lines as a result of the ongoing success of the company’s growth and innovation strategy. Operating profit increased from $18 million to $37 million compared to the same period last year, primarily due to increased volumes and an improved cost structure, including the effects from the exit of the COC business. Operating EBITDA increased 32% to $66 million compared to the same quarter last year.

Acetate Products

Acetate Products delivered improved and sustainable performance, benefiting from its revitalization strategy. Net sales increased 6% to $171 million compared to the same period last year. Higher

pricing on continued strong demand and increased flake volumes more than offset lower tow volumes resulting from the 2005 shutdown of the company’s Canadian tow plant. Operating profit increased to $23 million from $4 million as higher pricing, lower other charges, and savings from restructuring more than offset higher raw material and energy costs. Operating EBITDA for the quarter increased from $16 million to $29 million.

Performance Products

Net sales for Performance Products were $41 million, an 11% decrease from the same period last year due to a 6% decrease in volume and pricing. The decrease in pricing was in line with the company’s expectations, and the decrease in volume was primarily due to timing of sales to the carbonated beverage industry in 2006 compared to 2005. Operating profit was $10 million for the quarter compared to $13 million in the third quarter of last year. Operating EBITDA was $13 million compared to $16 million in the third quarter of last year.

Taxes

The 25% tax rate for adjusted earnings per share was favorable to the company’s previous estimate of 28% and accounted for a $0.03 per share positive impact in the third quarter. The tax rate for adjusted earnings per share reflects the benefits of utilizing the company’s net operating losses and differs significantly from the U.S. GAAP tax rate of 40% for the third quarter. This difference is primarily due to the impact of the reversal of purchase accounting valuation allowances related to net operating losses in the United States. Expected cash taxes are not impacted by these items and remain at the high end of the company’s previously forecasted range of between $60 and $100 million for 2006.

Equity and Cost Investments

Total dividends received from equity and cost investments were $33 million compared to $47 million in the same period last year. The expected decrease was mainly due to lower dividends from the Ibn Sina

cost investment in Saudi Arabia due to timing of payments. Earnings from equity and cost investments decreased to $36 million from $54 million, primarily due to lower cost investment dividends.

Cash Flow

During the third quarter, the company generated $257 million of cash from operating activities. The company continued to generate strong cash flow with $415 million in cash from operating activities during the first nine months of 2006, compared to $513 million in the same period last year. The year over year decrease is primarily due to the impact of favorable inventory reduction associated with the hurricanes in 2005, an increase in working capital associated with 2006 revenue growth, and timing of other cash payments.

Net debt at the end of the third quarter was $2,936 million, a decrease of $111 million from the end of 2005 and a decrease of $204 million from the end of the second quarter of 2006. Effective in the fourth quarter of 2006, the company expects to lower the borrowing costs on its senior credit facility by reducing the margin over LIBOR from 2.00% to 1.75% on approximately $1.3 billion of the U.S. dollar denominated portion of the Term Loans due to overall leverage ratio improvement.

Outlook

The company now expects its full year adjusted earnings per share to be between $2.70 and $2.80, based on 171.2 million diluted shares outstanding, compared to its previous guidance range of between $2.50 and $2.80. Full year 2005 results were $2.24. Fourth quarter results are expected to reflect traditional seasonality across the businesses but should benefit from lower raw material and energy costs as compared to last year. The company expects the full year tax rate for adjusted earnings per share to be approximately 27%.

“Our continued positive outlook demonstrates our confidence in the underlying strength of our businesses and their ability to deliver sustainable earnings,” Weidman said. “Our integrated, hybrid model and relentless pursuit of our company strategy has established a highly successful, global platform for strong performance and future growth.”

Reconciliation of Non-U.S. GAAP Measures to U.S. GAAP

This release reflects three performance measures, operating EBITDA, adjusted earnings per share and net debt as non-U.S. GAAP measures. The most directly comparable financial measure presented in accordance with U.S. GAAP in our consolidated financial statements for operating EBITDA is operating profit; for adjusted earnings per share is earnings per common share-diluted; and for net debt is total debt.

Use of Non-U.S. GAAP Financial Information

•

Operating EBITDA, a measure used by management to measure performance, is defined as operating profit from continuing operations, plus equity in net earnings from affiliates, other income and depreciation and amortization, and further adjusted for other charges and adjustments. Our management believes operating EBITDA is useful to investors because it is one of the primary measures our management uses for its planning and budgeting processes and to monitor and evaluate financial and operating results. Operating EBITDA is not a recognized term under U.S. GAAP and does not purport to be an alternative to operating profit as a measure of operating performance or to cash flows from operating activities as a measure of liquidity. Because not all companies use identical calculations, this presentation of operating EBITDA may not be comparable to other similarly titled measures of

			other companies. Additionally, operating EBITDA is not intended to be a measure of free cash flow for management’s discretionary use, as it does not consider certain cash requirements such as interest payments, tax payments and debt service requirements nor does it represent the amount used in our debt covenants.
	•		Adjusted earnings per share is a measure used by management to measure performance. It is defined as net earnings (loss) available to common shareholders plus preferred dividends, adjusted for other charges and adjustments, and divided by the number of basic common shares, diluted preferred shares, and options valued using the treasury method. We provide guidance on an adjusted earnings per share basis and are unable to reconcile forecasted adjusted earnings per share to a GAAP financial measure because a forecast of Other Items is not practical. We believe that the presentation of this non-U.S. GAAP measure provides useful information to management and investors regarding various financial and business trends relating to our financial condition and results of operations, and that when U.S. GAAP information is viewed in conjunction with non-U.S. GAAP information, investors are provided with a more meaningful understanding of our ongoing operating performance. This non-U.S. GAAP information is not intended to be considered in isolation or as a substitute for U.S. GAAP financial information.
	•		Net debt is defined as total debt less cash and cash equivalents. We believe that the presentation of this non-U.S. GAAP measure provides useful information to management and investors regarding changes to the company’s capital structure. Our management and credit analysts use net debt to evaluate the company’s capital structure and assess credit quality. This non-U.S. GAAP information is not intended to be considered in isolation or as a substitute for U.S. GAAP financial information.

Results Unaudited

The results presented in this release, together with the adjustments made to present the results on a comparable basis, have not been audited and are based on internal financial data furnished to management. Quarterly results should not be taken as an indication of the results of operations to be reported for any subsequent period or for the full fiscal year.

*		See Table 7 for details
**		The U.S. GAAP tax rate for the three months ended September 30, 2006 is 40% and nine months ended September 30, 2006 is 32%. The company’s adjusted tax rate for the three months ended September 30, 2006 is 25% and the resulting year to date adjusted tax rate is 27%. The difference between our US GAAP taxes and our adjusted taxes are due to: (i) the favorable impact of purchase accounting on our net operating losses ($23 million), and (ii) the elimination of discrete tax items not related to the current period ($4 million).
