Dallas, April 21, 2008: Celanese Corporation (NYSE: CE) today reported record net sales of $1,846 million, a 19 percent increase from the prior year period, primarily due to higher pricing on continued strong demand in its acetyl intermediates and downstream businesses, favorable currency impacts associated with the company’s global presence, and increased volumes related to growth in Asia. Operating profit rose to $234 million from $206 million, as the increased sales more than offset higher raw material and energy costs and spending primarily associated with the company’s expansion in China. Net earnings were $145 million compared with $201 million in the prior year period. The prior year’s net earnings included $79 million of earnings from discontinued operations related to the company’s divestiture of its oxo alcohol business and the closure of its Edmonton methanol facility during 2007.

Adjusted earnings per share for the first quarter were a record $1.06 compared with $0.77 in the same period last year. The results excluded $22 million of pre-tax expenses primarily associated with the company’s ongoing restructuring efforts. The current period’s results also included a $0.04 per share net benefit related to the company’s share repurchases executed in the last year. Operating EBITDA was $381 million versus $315 million in the prior year period, also record performance for the company.

“Our first quarter performance illustrates the strength of our integrated business model, our solid operating fundamentals, and our clear focus on growth and value creation,” said David Weidman, chairman and chief executive officer. “Despite ongoing sluggish demand in certain North American consumer segments and high raw material and energy costs across our businesses, Celanese delivered record results.”

Recent Highlights

	•		Remains on track to commence additional operations at its Nanjing, China, integrated chemical complex with four previously announced units to begin production within the next year.
	•		Opened a customer application development center in Shanghai, China, to support growth in the region for Ticona’s engineering polymers business.
	•		The Celanese board of directors authorized the company to repurchase up to $400 million of its Series A common stock. During the quarter, the company repurchased $60 million of its outstanding common shares.
	•		Upgraded by Moody’s Investors Service with a positive outlook and corporate credit rating of ‘Ba2’ from ‘Ba3.’

First Quarter Segment Overview

Advanced Engineered Materials
Advanced Engineered Materials continued to experience strong growth, particularly in Asia and non-transportation applications, with the successful implementation of new product solutions. Net sales increased to $294 million from $262 million in the same period last year, due to higher volumes and positive currency impacts. The increase was partially offset by lower average pricing primarily due to product and geographic mix. Operating profit decreased to $30 million from $36 million in the same period last year

as the increased volume was offset by continued high petroleum-based raw material and energy costs, as well as increased investment in Ticona’s growth strategy in China. Operating EBITDA decreased to $60 million from $67 million in the prior year period, primarily due to higher raw material and energy costs and lower earnings from its equity affiliates.

Consumer Specialties
Consumer Specialties continued to execute its strategy to provide higher, sustainable earnings. Net sales increased five percent to $282 million compared with the same period last year, driven by higher pricing on continued strong demand, sales from the Acetate Products Limited (APL) acquisition, which was completed in 2007, and positive currency impacts. The increase was partially offset by lower acetate flake volumes resulting from the company’s strategic decision to shift flake production to its China ventures. Operating profit was $50 million, $2 million higher than the prior year period’s results, as the company continued to drive cost synergies from the APL acquisition. Operating EBITDA increased to $65 million from $60 million in the same period last year as the higher pricing and lower manufacturing costs offset significantly higher energy and raw material costs.

Industrial Specialties
Revitalization of the Industrial Specialties businesses is underway and delivering improved results. Net sales increased to $365 million from $346 million in the same period last year, primarily driven by higher pricing on continued strong demand and favorable currency impacts. The increase was partially offset by lower volumes primarily related to continued softness in North American housing and construction segments, elevated European demand levels in 2007 prior to a German tax law change, and a strategic focus on higher value-added applications. Operating profit was $17 million compared with $12 million in the prior year period as the higher pricing more than offset higher raw material costs, primarily for vinyl acetate monomer, and the lower volumes. Additionally, Industrial Specialties benefited from the positive impact of rebuilding inventory during the quarter following a constrained supply in 2007. Operating EBITDA was $36 million compared with $26 million in the first quarter of 2007.

Acetyl Intermediates
Acetyl Intermediates experienced significant sales and earnings growth from its strategic expansions in Asia and a continued strong business environment for its products. Net sales were $1,096 million, a 31 percent increase from the same period a year ago, driven by volume growth from its Nanjing acetic acid unit, which began production in mid-2007, and higher pricing on continued strong demand for acetyl products across North America, Europe and Asia. Operating profit increased to $177 million from $132 million and operating EBITDA increased to $246 million from $174 million in the same period last year as volume and pricing more than offset higher raw material and energy costs in the period. Increased dividends from the company’s Ibn Sina methanol and MTBE cost affiliate also drove the improved operating EBITDA.

Taxes
The tax rate for adjusted earnings per share was 26 percent in the first quarter of 2008 compared with 28 percent in the first quarter of 2007. The U.S. GAAP effective tax rate for continuing operations for the first quarter of 2008 was 33 percent compared with 29 percent in the first quarter of 2007. The higher effective tax rate is primarily due to accounting accruals and the U.S. tax effect on increased foreign earnings and dividends, which were partially offset by increased earnings in lower tax jurisdictions. The tax rate for adjusted earnings per share is based upon the company’s previous guidance which did not include these items. Cash taxes for the first quarter of 2008 were $30 million, approximately $41 million lower than the prior year period, primarily due to the timing of tax benefits associated with the company’s recapitalization transaction in 2007.

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 $38 million in the first quarter, a $5 million increase from the prior year period, as higher dividends from the company’s Ibn Sina cost affiliate offset lower earnings from the Advanced Engineered Materials equity affiliates. Equity and cost investment dividends, which are included in cash flows, were $71 million compared with $45 million in the prior year period.

Cash Flow
During the first quarter of 2008, the company generated $166 million in cash from operating activities versus $12 million in the prior year period, driven by strong business performance, lower cash taxes and lower cash used in

discontinued operations. During the quarter, the company repurchased $60 million of its outstanding common shares and has an additional $340 million in authorized purchases remaining. Net debt at the end of the first quarter was $2,841 million, an increase of $110 million from the end of the fourth quarter of 2007, primarily driven by the use of cash for share repurchases and the foreign currency translation impact on non-U.S. dollar-denominated debt. Cash and cash equivalents at the end of the first quarter were $763 million versus $825 million at the end of the fourth quarter of 2007.

Outlook
Based on continued execution of its growth strategy across all of its businesses, a stronger pricing environment for acetyls and continued global demand growth, the company increased its full year outlook for adjusted earnings per share to between $3.60 and $3.85 from its previous guidance range of between $3.40 and $3.70. On a comparable basis, 2007 results were $3.29 per share. The guidance is based on an adjusted tax rate of 26 percent and an estimated year-end weighted average of 167 million diluted shares outstanding. The company also increased its operating EBITDA guidance range to between $1,355 million and $1,415 million from its previous range of between $1,290 million and $1,360 million.

“We continue to see challenges in North America, an overall slower European economy and continued high and volatile raw material and energy costs; however, our global integrated business model continues to deliver strong earnings growth,” Weidman said. “With our well-defined growth strategy, strong cash generation, and attractive industry fundamentals, Celanese is positioned to deliver higher, sustainable earnings and create significant value for our shareholders in 2008 and beyond.”

As a global leader in the chemicals industry, Celanese Corporation makes products essential to everyday living. Our products, found in consumer and industrial applications, are manufactured in North America, Europe and Asia.

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. All forward-looking statements are based upon current expectations and beliefs and various assumptions. 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 original guidance communicated at the company’s investor day in December 2007. 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. 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.

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.
