Dallas, February 3, 2009: Celanese Corporation (NYSE: CE), a leading global chemical company, today reported fourth quarter 2008 net sales of $1,286 million, a 27 percent decrease from the prior year period, driven by significantly lower volumes on weak global demand and unprecedented inventory destocking throughout its end-consumer supply chains. Operating profit was a loss of $152 million compared with a profit of $324 million in the same period last year. Results included fixed asset impairment charges of $94 million associated with the potential closure of the company’s acetic acid and vinyl acetate monomer (VAM) production facility in Pardies, France, and its VAM production unit in Cangrejera, Mexico, as well as other actions that the company is taking. Net earnings were a loss of $159 million compared with a profit of $214 million in the same period last year.

During the fourth quarter of 2008, the company aggressively managed its global production capacity in order to minimize inventory levels and optimize its working capital and cash positions. The company estimated that the total non-cash inventory accounting impact, which includes the negative effects of first-in, first-out (FIFO) accounting and inventory draw due to lower production levels, was approximately $101 million in the period.

Adjusted earnings per share for the fourth quarter of 2008 were a loss of $0.38 compared with a profit of $0.93 in the same period last year. These results exclude approximately $105 million of other charges and adjustments, including the fixed asset impairment charges. Operating EBITDA was $68 million in the fourth quarter of 2008 versus $349 million in the prior year period.

“During the fourth quarter, historically weak market conditions drove a dramatic decline in overall global demand for many industries that we supply. While our Consumer Specialties segment continued to deliver high earnings levels, recessionary trends, coupled with an unprecedented inventory destocking, resulted in sharp volume declines in our other businesses,” said David Weidman, chairman and chief executive officer. “We are pleased that the aggressive actions that we have taken to align our business operations and production with current demand levels resulted in solid cash generation.”

Recent Highlights

	•		Announced the assessment of the potential closure of acetic acid and vinyl acetate monomer (VAM) production in Pardies, France, and VAM production in Cangrejera, Mexico, as well as certain other actions the company is considering.
	•		Released its 2008 Sustainability Report, which details the company’s industry-leading commitment to safety, health and the environment across its worldwide operations. The report also highlights best practices driven by the company’s employees around the world. The company’s 2008 global OSHA Injury Rate (OIR), or the annual number of injuries per 100 employees, was 0.26, which is among the best in the chemical industry.
	•		Reached an agreement with the Frankfurt, Germany, Airport (Fraport AG) to receive an advance payment of € 322 million associated with the relocation of its Ticona business in Kelsterbach, Germany. This advance payment will be in lieu of the payments of € 200 million and € 140 million originally scheduled to be paid in June 2009 and June 2010, respectively.

Fourth Quarter Segment Overview

Consumer Specialties
Consumer Specialties continued to execute its strategy to deliver higher, sustainable earnings. Net sales in the quarter were $286 million, up $7 million from the prior year period, primarily driven by higher pricing on continued strong demand. The higher pricing was partially offset by overall lower volumes and unfavorable currency effects. The lower volumes were primarily attributed to lower acetate flake sales resulting from the company’s decision to shift flake production to its China ventures. Operating profit was $52 million, a $17 million decrease from the prior year period. Fourth quarter 2007 results included a one-time gain of $22 million associated with the sale of the company’s Edmonton, Canada facility. Operating EBITDA was $65 million, up 14 percent from the same period last year.

Industrial Specialties Industrial Specialties’ successful new market strategy in Asia and favorable pricing were offset by overall weaker demand in North America and Europe. Net sales in the quarter were $277 million, a $54 million decrease from the same period last year, driven by lower overall volumes and unfavorable currency effects. The company achieved higher overall pricing across all business lines to partially offset the lower volumes. Operating profit in the quarter was a loss of $8 million compared with a profit of $26 million in the prior year

period, primarily driven by the lower volumes and inventory accounting impacts of $15 million. Operating EBITDA was $8 million compared with $41 million in the prior year period.

Advanced Engineered Materials
Advanced Engineered Materials maintained increased pricing for its high value-in-use product portfolio but experienced significant volume pressure across many of its product lines. Net sales in the quarter were $195 million, a $58 million decrease from the prior year period. The higher pricing, aided by positive product mix, was not able to offset the lower overall volumes primarily driven by significant reductions in U.S. and European automotive production. Many non-automotive applications, such as medical, filtration and electronics, as well as applications for the China market, experienced only modest declines in the quarter. Operating profit in the fourth quarter was a loss of $48 million compared with a profit of $30 million in the prior year period and included $23 million of impact related to inventory accounting and $16 million associated with fixed asset impairments. Operating EBITDA, which excludes the impact of the asset impairments, was a loss of $3 million compared with a profit of $45 million in the same period last year. Additionally, equity in net earnings from Advanced Engineered Materials’ strategic equity affiliates were $5 million lower than the prior year period and contributed $4 million in the quarter.

Acetyl Intermediates
Acetyl Intermediates experienced a dramatic decline in overall global demand for its products due to prolonged inventory destocking in its end-market customer supply chain and lower pricing for acetyl products. Net sales in the quarter were $656 million, a 39 percent decrease from the same period last year, primarily due to the lower volumes. The lower pricing was driven by lower overall demand and a decrease in raw material input costs, which impacted the formula-based pricing for many acetyl derivatives. Operating profit was a loss of $116 million compared with a profit of $276 million in the same period last year and included $75 million in net other charges and adjustments, primarily related to fixed asset impairments. Lower raw material and energy costs could not offset the lower volumes and decreased pricing in the quarter. The impact of inventory accounting totaled approximately $63 million in the current period. Operating EBITDA, which excludes the other charges and adjustments, was $21 million compared with $231 million in the same period last year. Dividends from the company’s Ibn Sina cost affiliate increased to $29 million compared to $22 million a year ago.

Taxes
The tax rate for adjusted earnings per share was 26 percent in the fourth quarter of 2008 compared with 28 percent in the fourth quarter of 2007. The effective tax rate for continuing operations for 2008 was 15 percent versus 25 percent in 2007. The effective tax rate for 2008 is lower primarily due to increased earnings in jurisdictions with reduced tax rates and the U.S. impact of foreign operations. Cash taxes for 2008 were $98 million compared with $191 million in 2007, primarily as a result of tax losses in the U.S. and the timing of cash taxes in certain jurisdictions.

Equity and Cost Investments
Earnings from equity investments and dividends from cost investments, which are reflected in the company’s adjusted earnings and operating EBITDA, totaled $37 million in the fourth quarter of 2008 compared with $40 million in the prior year period. The decrease is attributed to lower earnings from the company’s Advanced Engineered Materials equity affiliates. Equity and cost investment dividends, which are included in cash flows, were $31 million compared with $26 million in the same period last year, driven by higher dividends from the company’s Ibn Sina cost affiliate.

Cash Flow
Net debt at the end of the fourth quarter of 2008 was $2,857 million, a decrease of $179 million from the end of the third quarter of 2008, on strong cash flow during the period. Additionally, the company made net repayments of $72 million in short term borrowings and affiliate debt in the quarter. Net debt at the end of the fourth quarter of 2007 was $2,731 million.

“Our current capital structure is stable, flexible and low-cost,” said Steven Sterin, senior vice president and chief financial officer. “We are focused on cash generation and committed to investing in our businesses, and funding our restructuring and productivity initiatives. At the same time, we are continuing to position Celanese for the future. Receiving the advance payment from Fraport increases our flexibility and is a cost-effective way to manage the expenses and cash associated with the relocation of our Ticona business in Kelsterbach, Germany.”

The company continued to generate strong cash flow during the twelve months of 2008 and reported a cash inflow of $568 million from operating activities, up $2 million from the prior year period. Favorable trade working capital and lower cash taxes paid helped to offset the lower operating performance.

Cash used in investing activities totaled $184 million for the full year 2008 compared with $143 million of cash received in the prior year. During the fourth quarter of 2008, the company incurred $63 million of costs associated with the relocation of Ticona’s Kelsterbach production facility. Additionally, the company received net proceeds of $109 million related to the sale of marketable securities in the period.

Cash and cash equivalents at the end of the fourth quarter were $676 million compared with $825 million at the end of the fourth quarter of 2007. During 2008, the company repurchased a total of $378 million of its outstanding common shares.

Outlook
The company expects the inventory destocking to diminish in 2009, but does not foresee a short-term recovery in the global economic environment. While the company has chosen not to provide a full-year outlook for 2009, it does expect earnings to improve from fourth quarter levels throughout the year, as the impact of destocking and the negative effects of inventory accounting decrease.

The company announced that it is taking aggressive actions in response to the expected prolonged weak demand environment. These actions include an assessment of its current manufacturing footprint and reductions of its overall fixed cost structure. Initial reductions have already been initiated and total between $100 million and $120 million annually.

“With the current global economic recession and continued weak consumer demand, we would expect volumes to remain under pressure in 2009, even with the easing of inventory destocking. Margins should benefit from lower raw material and energy costs as the impact of inventory accounting subsides. Although our businesses are well positioned, we will continue to take the necessary, aggressive actions required to align our operations and staffing with the short-term demand environment, while strengthening our businesses for the long-term,” said Weidman.

Forward-Looking Statements

This release may contain “forward-looking statements,” which include information concerning the company’s plans, objectives, goals, strategies, future revenues or performance, capital expenditures, financing needs and other information that is not historical information. When used in this release, the words “outlook,” “forecast,” “estimates,” “expects,” “anticipates,” “projects,” “plans,” “intends,” “believes,” and variations of such words or similar expressions are intended to identify forward-looking statements.

There can be no assurance that the company will realize these expectations or that these beliefs will prove correct. There are a number of risks and uncertainties that could cause actual results to differ materially from the forward-looking statements contained in this release. Numerous factors, many of which are beyond the company’s control, could cause actual results to differ materially from those expressed as forward-looking statements. Certain of these risk factors are discussed in the company’s filings with the Securities and Exchange Commission. Any forward-looking statement speaks only as of the date on which it is made, and the company undertakes no obligation to update any forward-looking statements to reflect events or circumstances after the date on which it is made or to reflect the occurrence of anticipated or unanticipated events or circumstances.

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

This release reflects five performance measures, operating EBITDA, affiliate EBITDA, adjusted earnings per share, net debt and adjusted free cash flow, 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 affiliate EBITDA is equity in net earnings of affiliates; for adjusted earnings per share is earnings per common share-diluted; for net debt is total debt; and for adjusted free cash flow is cash flow from operations.

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. We provide guidance on operating EBITDA and are unable to reconcile forecasted operating EBITDA to a GAAP financial measure because a forecast of Other Charges and Adjustments is not practical. 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.
	•		Affiliate EBITDA, a measure used by management to measure performance of its equity investments, is defined as the proportional operating profit plus the proportional depreciation and amortization of its equity investments. Affiliate EBITDA, including Celanese Proportional Share of affiliate information on Table 8, is not a recognized term under U.S. GAAP and is not meant to be an alternative to operating cash flow of the equity investments. The company has determined that it does not have sufficient ownership for operating control of these investments to consider their results on a consolidated basis. The company believes that investors should consider affiliate EBITDA when determining the equity investments’ overall value in the company.
	•		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 without unreasonable effort 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.
	•		The tax rate used for adjusted earnings per share is the tax rate based on our initial guidance, less changes in uncertain tax positions. We adjust this tax rate during the year only if there is a substantial change in our underlying operations; an updated forecast would not necessarily result in a change to our tax rate used for adjusted earnings per share. The adjusted tax rate may differ significantly from the tax rate used for U.S. GAAP reporting in any given reporting period. It is not practical to reconcile our prospective adjusted tax rate to the actual U.S. GAAP tax rate in any future period.
	•		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.
	•		Adjusted free cash flow is defined as cash flow from operations less capital expenditures, other productive asset purchases, operating cash from discontinued operations and certain other charges and adjustments. 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 cash flow. Our management and credit analysts use adjusted free cash flow to evaluate the company’s liquidity 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.
