Dallas, July 21, 2011: Celanese Corporation (NYSE: CE), a global technology and specialty materials company, today reported second quarter 2011 net sales of $1,753 million, a 16 percent increase from the prior year period, primarily driven by higher pricing across all operating segments and favorable currency impacts. Higher pricing was a result of recovery of higher raw material costs and temporarily elevated industry utilization reflected in its Acetyl Intermediates segment, as well as strong demand throughout its global businesses. Margins expanded and operating profit increased to $209 million from $156 million in the same period last year. This quarter's results included other charges and other adjustments totaling $33 million, primarily related to the company's planned European capacity expansion and relocation in its Advanced Engineered Materials segment. Net earnings were $203 million compared with $160 million in the same period last year. Diluted earnings per share from continuing operations were $1.29 compared with $1.03 in the prior year period.

Adjusted earnings per share in the second quarter of 2011 rose 48 percent to $1.66 from $1.12 in the prior year period. The tax rate and diluted share count for adjusted earnings per share in the current period were 17 percent and 159.2 million,

1

respectively. Operating EBITDA was $441 million, up 33 percent from the second quarter of 2010. Adjusted earnings per share and operating EBITDA excluded other charges and other adjustments in both periods.

“Celanese delivered our best quarterly earnings ever on strong demand across all of our end markets as we aggressively mitigated the impact of higher raw material and energy costs. Our Acetyl Intermediates business also demonstrated the strength of its differentiated technology and low cost position as industry utilization was temporarily elevated, significantly contributing to this quarter's earnings," said David Weidman, chairman and chief executive officer. “Our innovation efforts and presence in emerging geographies are also driving growth across our diversified product portfolio, demonstrating our success in executing our strategic objectives.”

Recent Highlights

• Published independent third-party analyses of Celanese TCX™, its proprietary technology for ethanol production. Under non-disclosure agreements to protect intellectual property rights and maintain confidentiality, Fluor Corporation and WorleyParsons evaluated the company's advanced ethanol technology that uses basic hydrocarbon feedstocks.

• Doubled the capacity of its vinyl acetate ethylene (VAE) unit in Nanjing, China. The expanded unit started production in the second quarter of 2011 and is expected to meet the increased global demand for innovative specialty solutions in vinyl-based emulsions.

• Announced it will nearly double production at its Celstran^® long-fiber reinforced thermoplastic (LFT) manufacturing unit in Nanjing, China by the end of the fourth quarter of 2011. The unit came online in 2008 with an initial nameplate capacity of 5,000 tons per year.

• Successfully completed a public offering of $400 million in aggregate principal amount of senior unsecured notes at 5.875 percent due 2021. The company used the net proceeds from the offering, plus cash on hand, to retire $516 million of existing senior secured credit facility indebtedness that was set to mature in 2014.

• Polyplastics Co., Ltd. (Polyplastics), one of the company's strategic equity affiliates, announced a 90,000 ton per year expansion to increase polyacetal production capacity in Malaysia that is expected to be operational in early 2014.  The expansion is currently anticipated to be funded locally by Polyplastics.

• Announced plans to accelerate industrial ethanol production in China six to twelve months earlier than previously expected. In addition to its previously announced plans for one, and possibly two greenfield units, the company plans to modify and enhance its existing integrated acetyl facility at the Nanjing Chemical Industrial Park with its TCX^™ advanced technology, adding approximately 200,000 tons of ethanol production capacity by mid-2013.

• Broke ground on the previously announced plans for a technology development unit for ethanol production at its facility in Clear Lake, Texas, which is now expected to be commissioned by mid-2012. The company also intends to construct a new research and development facility at the Clear Lake site to continue the advancement of its acetyl and TCX^™ technologies.

Second Quarter Segment Overview

Advanced Engineered Materials

Advanced Engineered Materials continued to execute its strategic business model of customer-focused innovation and value-in-use pricing, delivering improved earnings in the quarter. Net sales for the second quarter of 2011 were $346 million compared with $282 million in the same period last year, driven by higher pricing, primarily related to improved product mix and increased value-in-use pricing, favorable currency impacts and revenue related to the company's recent acquisition. Demand for the company's innovative applications remained strong in the period, however, volumes for the company's polyacetal products were constrained due to the company's planned European production capacity expansion. Operating profit in the second quarter was $27 million, including $22 million of other charges and other adjustments primarily associated with the capacity expansion in Europe, compared with $40 million of operating profit in the prior year period. Higher pricing more than offset increased raw material costs and the company's investments for future growth. Operating EBITDA, which excluded the other charges and other adjustments, was $107 million compared with $98 million in the same period last year. Total equity earnings from the company's affiliates were $39 million, unchanged from the prior year period. Earnings in the company's Polyplastics venture were modestly impacted by the natural disasters in Japan earlier this year, but were offset by strong performance in the other affiliates.

Consumer Specialties

Consumer Specialties continued to deliver sustained earnings, reflecting the company's leading global positions and strong strategic affiliate performance. Net sales for the second quarter of 2011 were $291 million, unchanged from the prior year period, as increased pricing and favorable currency offset lower volumes. Volumes in the second quarter of 2011 were lower when compared to the prior year period, as the prior year's results reflected volume recovery from the production outage at its acetate manufacturing facility in Narrows, Virginia during the first quarter of 2010. Operating profit was $48 million compared with $64 million in the same period last year as higher pricing was more than offset by higher raw material and energy costs. The current period's results included $10 million of other charges and other adjustments, primarily related to the previously announced closure of its acetate manufacturing facility in Spondon, Derby, United Kingdom. Operating EBITDA, which excluded the other charges and other adjustments, was $147 million compared with $149 million in the prior year period. Dividends from the company's acetate China ventures were $78 million compared with $71 million in the same period last year.

Industrial Specialties

Industrial Specialties continued to realize benefits from its innovation efforts and increased global demand, delivering improved results and expanded margins in the quarter. Net sales in the quarter were $329 million compared with $269 million in the same period last year, primarily driven by higher pricing and favorable currency impacts. Global pricing increased across the segment, driven by continued strong global demand and recovery of higher raw material costs. Results also benefited from higher volumes associated with the company's innovative offerings in the emulsions business, particularly in North America and Europe, and its value-added EVA performance polymers products in Asia. Operating profit in the current period was $28 million compared with $16 million in the same period last year as the higher pricing and volume growth more than offset higher raw material costs. Operating EBITDA was $40 million compared with $26 million in the prior year period.

3

Acetyl Intermediates

Acetyl Intermediates delivered improved results year-over-year as its advantaged technology position led to expanded margins amid favorable industry conditions. Net sales for the second quarter of 2011 increased to $914 million from $782 million in the prior year period, driven by higher pricing across major acetyl derivative product lines in all regions and favorable currency impacts. The significantly increased pricing was driven by temporarily elevated industry utilization due to planned and unplanned outages of acetyl producers, reflecting the industry's technology-differentiated cost curve. Additionally, pricing reflected the recovery of higher raw material costs compared with the same period last year. Although the company's production turnarounds resulted in lower volumes compared to the prior year, overall global industry demand for acetyl products remained strong. Operating profit in the current period rose to $152 million from $68 million in the same period last year as the increased pricing and favorable currency impacts more than offset the higher raw material input costs and lower volumes. Operating EBITDA was $177 million compared with $96 million in the second quarter of 2010.

Taxes

The tax rate for adjusted earnings per share was 17 percent in the second quarter of 2011 compared with 20 percent in the second quarter of 2010. The effective tax rate for continuing operations for the second quarter of 2011 and 2010 was 27 percent. Net cash tax payments were $30 million in the first six months of 2011 compared with $65 million in the first six months of 2010. The decrease in net cash taxes paid is primarily the result of tax refunds received in certain jurisdictions.

Equity and Cost Investments

Earnings from equity investments and dividends from cost investments, which are reflected in the company's earnings and operating EBITDA, were $125 million in the second quarter of 2011, $8 million higher than the same period last year. Equity and cost investment dividends, which are included in cash flows, were $124 million, a $17 million increase from the prior year period. Dividends from the company's acetate China ventures were $78 million in the second quarter of 2011, a $7 million increase from the prior year's results.

Earnings in equity investments for Ticona's strategic affiliates in Asia in the second quarter of 2011 were $17 million, $2 million higher than the same period last year. Proportional affiliate EBITDA in excess of equity net earnings decreased to $15 million from $23 million in the prior year period.

Ticona's Middle Eastern affiliates, which include the company's Ibn Sina affiliate, reported equity in net earnings of $22 million in the second quarter of 2011, a $2 million decrease from the same period last year. The company's proportional affiliate EBITDA in excess of equity net earnings for the Middle Eastern affiliates was $8 million, unchanged from the prior year period.

The company's total proportional affiliate EBITDA for the second quarter of 2011 was $83 million, $3 million lower than the prior year period and $37 million more than reported in the company's operating EBITDA. As of June 30, 2011, the company's total proportional net debt of affiliates was $125 million.

Cash Flow

The company continued to generate positive cash flow in 2011. During the first six months of 2011, the company generated $316 million in cash from operating activities compared with $219 million in the prior year period as the higher earnings offset increased working capital and interest expense. Cash used in investing activities was $133 million in the first six months of 2011 compared with $275 million in the same period last year. During the first six months of 2011, the company spent $114 million of capital expenditures related to the relocation of Ticona's operations in Kelsterbach, Germany, and received its final payment of $158 million related to the relocation. The 2010 results included $151 million of capital expenditures related to the Ticona relocation and a cash outflow of $46 million related to the company's acquisition of the Zenite^® LCP and Thermx^® PCT product lines from DuPont Performance Polymers. Net cash used in financing activities was $198 million during the first six months of 2011 compared with $78 million in the prior year period. During the second quarter of 2011, the company used a net of $116 million to prepay one of its term loan facilities. Net debt at the end of the second quarter of 2011 was $2,307 million, a $171 million decrease from the end of 2010.

Outlook

Based on the record performance in the second quarter, and an expectation for sustained global economic growth, the company increased its outlook for full year 2011 results. The company now expects 2011 operating EBITDA to be approximately $275 million higher than 2010's results of $1,122 million and adjusted earnings per share to be approximately $1.20 higher than 2010's results of $3.37, based on a tax rate and diluted share count of 17 percent and 159.2 million shares, respectively. The company had previously expected 2011 operating EBITDA and adjusted earnings per share to be at least $200 million and $0.85 higher than 2010, respectively.

“Advantaged technologies, leading global portfolio positions and innovative customer-focused solutions combined to deliver significant improvement in profitability in the first half of 2011 and are expected to drive sustained earnings growth for Celanese throughout the remainder of the year,” said Weidman. “Our integrated business model continues to demonstrate the resiliency it has successfully shown in the past, even in an environment of escalating raw material and energy costs. The temporarily expanded margins in acetyls should moderate to more normalized levels during the second half of the year. We remain on track throughout our businesses for our 2013 earnings growth objectives of at least $6.00 in adjusted earnings per share.”

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

This release reflects the following performance measures: operating EBITDA, business operating EBITDA, affiliate EBITDA and proportional affiliate EBITDA, adjusted earnings per share, and net debt as non-U.S. GAAP measures. These measurements are not recognized in accordance with U.S. GAAP and should not be viewed as an alternative to U.S. GAAP measures of performance. The most directly comparable financial measure presented in accordance with U.S. GAAP in our consolidated financial statements for operating EBITDA and business operating EBITDA is net income; for proportional affiliate EBITDA is equity in net earnings of affiliates; for affiliate 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 is defined by the company as net earnings less interest income plus loss (earnings) from discontinued operations, interest expense, taxes, and depreciation and amortization, and further adjusted for Other Charges and Adjustments as described in Table 7. We present operating EBITDA because we consider it an important supplemental measure of our operations and financial performance. We believe that operating EBITDA is more reflective of our operations as it provides transparency to investors and enhances period-to-period comparability of our operations and financial performance. Operating EBITDA is one of the measures management uses for its planning and budgeting process to monitor and evaluate financial and operating results and for the company's incentive compensation plan. Operating EBITDA should not be considered as an alternative to net income determined in accordance with U.S. GAAP. We may provide guidance on operating EBITDA and are unable to reconcile forecasted operating EBITDA to a U.S. GAAP financial measure because a forecast of Other Charges and Adjustments is not practical.

• Business operating EBITDA is defined by the company as net earnings less interest income plus loss (earnings) from discontinued operations, interest expense, taxes and depreciation and amortization, and further adjusted for Other Charges and Adjustments as described in Table 7, less equity in net earnings of affiliates, dividend income from cost investments and other (income) expense. This supplemental performance measure reflects the operating results of the company's operations without regard to the financial impact of its equity and cost investments.

• Affiliate EBITDA is defined by the company as operating profit plus the depreciation and amortization of its equity affiliates. Proportional affiliate EBITDA is defined by the company as the proportional operating profit plus the proportional depreciation and amortization of its 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 proportional affiliate EBITDA as an additional measure of operating results.

• Adjusted earnings per share is a measure used by management to measure performance. It is defined by the company 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 may provide guidance on an adjusted earnings per share basis and are unable to reconcile forecasted adjusted earnings per share to a U.S. 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. Note: The income tax rate used for adjusted earnings per share approximates the midpoint in a range of forecasted tax rates for the year. This range may include certain partial or full-year forecasted tax opportunities, where applicable, and specifically excludes changes in uncertain tax positions, discrete items and other material items adjusted out of our U.S. GAAP earnings for adjusted earnings per share purposes, and changes in management's assessments regarding the ability to realize deferred tax assets. We analyze this rate quarterly and adjust if there is a material change in the range of forecasted tax rates; an updated forecast would not necessarily result in a change to our tax rate used for adjusted earnings per share. The adjusted tax rate is an estimate and may differ 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 given future period.

• Net debt is defined by the company 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. Proportional net debt is defined as our proportionate share of our affiliates' net debt.
