Dallas, May 9, 2006: Celanese Corporation (NYSE: CE) today reported net sales increased 12% to $1,652 million for the first quarter compared to the same period last year on higher pricing with strong demand, mainly in the Chemical Products segment, as well as sales resulting from the acquisition of Acetex. Net sales were partially offset by negative currency impacts of 3%. Operating profit rose to $197 million versus $156 million in the same period last year, as higher net sales, continued cost improvements, and lower special charges helped to offset increased raw material costs and $5 million in stock based


compensation expense associated with the adoption of FAS 123(R). Net earnings increased significantly to $117 million compared to a loss of $10 million, primarily due to lower interest expense, including $102 million related to debt refinancing in 2005. Lower minority interest expense related to the company's increased ownership of outstanding Celanese AG shares also contributed to the increase in net earnings.

Adjusted earnings per share were a record $0.72 compared to $0.62 in the same period last year and excluded $10 million of expenses primarily related to the squeeze out of remaining minority shareholders of Celanese AG. The increase in earnings was driven primarily by the reduction in minority interests and supported by continued strong business performance.

Operating EBITDA for the first quarter rose to $304 million from $285 million in the same period last year. Operating EBITDA, a new non-GAAP performance measure for Celanese, takes operating profit and adds equity in net earnings from affiliates, other income (primarily income from cost investments), depreciation and amortization, and certain adjustments not indicative of underlying business results. These adjustments are consistent with those used to calculate adjusted earnings per share.

"Celanese had another excellent quarter. Our results demonstrate the strength of our integrated hybrid structure as our downstream businesses delivered improved performance year over year," said David Weidman, president and chief executive officer. "We are focusing our portfolio, expanding globally and relentlessly pursuing cost improvements to deliver on our commitments and create value for our shareholders."

RECENT BUSINESS HIGHLIGHTS

- Broke ground on a state of the art emulsions facility at the Nanjing, China chemical complex.

- Announced plans to invest in a new Celstran(R) long fiber reinforced thermoplastics (LFT) compounding plant in China.

- Launched VAntage Plus(TM), the company's next generation vinyl acetate monomer technology, at the Cangrejera, Mexico facility.

- Continued to make progress on completing the squeeze-out of remaining Celanese AG shareholders by setting the cash compensation for the minority shares at Euro 62.22 per share and signing a legal settlement with certain minority shareholders. There are currently less than 1 million minority shares outstanding.

First Quarter Segment Overview

CHEMICAL PRODUCTS

Chemical Products demonstrated the strength of its global franchise as the impact of recent capacity additions in acetyls was less than expected. Net sales increased from $1,044 million to $1,169 million as pricing improvements were driven by high utilization across the industry on strong demand and increased energy and raw material costs. Chemical Products also benefited from the inclusion of sales resulting from


the Acetex acquisition, which more than offset negative currency effects. In comparison to exceptional results in the first quarter of 2005, operating profit decreased from $177 million to $162 million, and operating EBITDA decreased from $226 million to $208 million. Downstream products experienced margin recovery. Price increases in basic products did not offset increases in energy and raw material costs.

TECHNICAL POLYMERS TICONA

Ticona performed well as it continued to increase its penetration in key applications. Net sales decreased from $239 million to $231 million primarily due to negative currency effects. Higher pricing and increased volume more than offset the loss of sales related to the COC business, which was divested in the fourth quarter of 2005. Volumes improved, particularly in the GUR, LCP and European polyacetal (POM) businesses, primarily driven by a stronger business environment in Europe. Operating profit increased from $39 million to $41 million, and operating EBITDA increased from $67 million to $69 million compared to the same period last year on margin recovery. Pricing and cost savings initiatives more than offset increases in energy and raw material costs.

ACETATE PRODUCTS

Acetate Products' significantly improved performance reflects the benefits of its ongoing revitalization efforts. Net sales increased by $2 million to $167 million compared to the same period last year as higher pricing and increased flake volumes more than offset lower volumes for tow. The lower tow volumes resulted from the shutdown of the company's Canadian tow plant while flake sales increased to its recently expanded China tow ventures. Operating profit increased by $13 million to $23 million and operating EBITDA increased from $20 million to $30 million compared to the same period last year. Higher pricing and savings from revitalization efforts more than offset lower overall sales volumes and higher raw material and energy costs.

PERFORMANCE PRODUCTS

Performance Products continued to demonstrate the strength of its core sweetener and food protection businesses. Net sales increased $2 million to $49 million compared to the same period last year. Volumes for Sunett(R) sweetener increased, reflecting continued growth in the global beverage and confectionary industry. Pricing for Sunett declined as expected while both volume and pricing for Sorbates increased in the quarter. Operating profit increased $4 million to $17 million and operating EBITDA increased $5 million to $21 million driven by robust volume increases and cost savings initiatives.

EQUITY AND COST INVESTMENTS

Dividends received from equity and cost investments totaled $24 million in the quarter compared to $50 million in the same period last year due to timing of dividend receipts in 2005. The income statement impact, consisting of earnings of equity investments and dividends from cost investments, was $28 million compared to $29 million.


"Our equity and cost investments continue to perform well and contribute significantly to our overall results," said John J. Gallagher III, executive vice president and chief financial officer. "While there is seasonality to our dividend flow, we expect income from equity and cost investments to be similar to last year's strong level of $150 million."

CASH FLOW

Net debt, a non-GAAP performance measure, increased from $3,047 million to $3,206 million during the quarter. The increase in net debt is primarily due to a seasonal increase in working capital, cash set aside for certain financial obligations, and the balance sheet impact of foreign currency exchange. Cash and cash equivalents at the end of the period were $312 million, a decrease of $78 million from year end 2005.

The first quarter is historically the seasonal low point for the company's cash generation. Celanese expects strong cash generation for the remainder of 2006.

TAXES

With increased earnings in higher tax jurisdictions and the accounting treatment of the reversal of valuation allowances under purchase accounting, the company's effective tax rate for the quarter was 28%, higher than the forecasted range of between 18% and 22%. The increase in the effective rate is not expected to affect projected cash taxes due to utilization of net operating losses and the non-cash nature of the valuation allowance accounting treatment.

OUTLOOK

The company reaffirmed its guidance for adjusted earnings per share for 2006 of between $2.50 and $2.90 based on 171.5 million diluted shares outstanding.

"Our earnings outlook for the year, driven by improved performance in our downstream businesses and high industry utilization in our basic businesses, continues to be positive," Weidman said. "With continued strong global demand, we expect a favorable supply environment for our basic products through 2008."

The forecasted tax rate used for this guidance range is 28%, a $0.27 per share impact versus the company's prior guidance of between 18% and 22%. The company now expects full year depreciation and amortization to be between $275 million and $300 million, lower than the original guidance of between $300 and $330 million, or $0.12 per share, due in part to purchase accounting adjustments related to the acquisition of Acetex. Despite the $0.15 per share negative net impact of these changes, the company maintains its earnings outlook.


The company expects adjusted earnings per share in the second quarter of 2006 to be similar to the first quarter 2006 results.

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 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 special charges and other 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 special charges and other adjustments, and divided by the number of basic common shares, diluted preferred shares, and options valued using the treasury method. 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.
