Celanese Corporation Reports Third Quarter 2022 Earnings

Celanese Corporation (NYSE: CE), a global chemical and specialty materials company, today reported third quarter 2022 GAAP diluted earnings per share of $1.76 and adjusted earnings per share of $3.94. The Company generated net sales of $2.3 billion in the third quarter, a 7 percent decrease from the prior quarter due to sequential decreases in price and volume of 3 percent and 2 percent, respectively, and a 2 percent unfavorable currency impact. Celanese navigated declines in European and Asian demand, customer destocking, and continued cost inflation to deliver third quarter consolidated operating profit of $308 million and adjusted EBIT of $510 million. On November 1, 2022, the Company successfully completed the acquisition of Mobility & Materials (M&M), acquiring a broad portfolio of engineered thermoplastics and elastomers, industry-renowned brands and intellectual property, global production assets, and a world-class organization. The acquisition establishes Celanese as the preeminent global specialty materials company and is expected to drive enhanced growth and free cash flow generation.

The difference between GAAP diluted earnings per share and adjusted earnings per share for the third quarter was primarily due to approximately $104 million in net interest expense related to bonds issued for the acquisition of M&M and $44 million in M&A-related costs.

"I thank the Celanese team for delivering third quarter adjusted earnings per share performance within less than 2 percent of our guidance despite demand deterioration and other unanticipated headwinds across the quarter," said Lori Ryerkerk, chairman and chief executive officer. "At the same time, I thank the many teams who diligently worked to successfully close the M&M acquisition on November 1. On behalf of us all, I warmly welcome our newest colleagues from M&M, whose dedication and contribution will make Celanese stronger."

Third Quarter 2022 Business Segment Overview

Engineered Materials

Engineered Materials generated net sales of $929 million in the third quarter reflecting a sequential price increase of 2 percent and a 3 percent unfavorable currency impact. Pricing expanded for the seventh consecutive quarter due to commercial actions to successfully offset continued cost inflation across raw materials and energy. Sequential volume declined by 1 percent as moderation in the legacy non-auto segments was offset by sequentially higher volume in automotive and medical as well as contributions from the restructuring of the KEPCO joint venture. Engineered Materials' medical segment was lifted by strong sequential growth in the medical implant business which recovered to pre-COVID demand in the third quarter. Engineered Materials delivered GAAP operating profit of $114 million and adjusted EBIT of $206 million, decreases from the prior quarter of $52 million and $18 million, respectively. Third quarter earnings were negatively impacted by approximately $15 million due to the rise in sequential natural gas costs and the impact of a one-month lag on the Engineered Materials energy surcharge. Affiliate earnings contributed an additional $16 million sequentially, primarily driven by strong performance of Ibn Sina.

Acetyl Chain

The Acetyl Chain generated third quarter net sales of $1.3 billion, including a 7 percent sequential decrease in pricing, 4 percent decrease in volume, and a 2 percent unfavorable currency impact. Pricing decreased primarily due to moderation in China acetic acid and VAM pricing across the third quarter. Volume decreased due to demand softness primarily in European and Chinese paints, coatings, and construction applications. As a result of these conditions, the Acetyl Chain took decisive actions across its production network to reduce cost and align with market demand. The VAM production unit in Frankfurt, Germany, the highest-cost facility in the global VAM network, was idled as the Company relied on other facilities to meet reduced European demand. Production operating rates in China and Singapore were also reduced in the third quarter across most production units. The Acetyl Chain further leveraged its global network to navigate a multi-week shutdown of the Clear Lake acetic acid plant to perform maintenance on an unanticipated mechanical issue. Despite these challenges, the business delivered third quarter GAAP operating profit of $315 million and adjusted EBIT of $322 million, at margins of 25 percent.

Acetate Tow

Acetate Tow generated net sales of $135 million during the third quarter, which reflected sequential volume and price increases of 10 percent and 3 percent, respectively. Third quarter GAAP operating loss was $3 million and adjusted EBIT was $27 million. Dividends from affiliates in the quarter were $30 million, a sequential decrease of $6 million.

Cash Flow and Tax

Celanese generated third quarter operating cash flow of $467 million and free cash flow of $325 million. Capital expenditures in the third quarter were $139 million. Celanese returned $73 million in cash to shareholders via dividends in the quarter.

The effective U.S. GAAP tax rate was 40 percent for the third quarter compared to 16 percent for the same quarter of 2021. The higher effective tax rate was primarily due to increases in valuation allowances on U.S. foreign tax credit carryforwards due to revised forecasts of foreign sourced earnings and increases in tax reserves related to ongoing income tax audits. The effective tax rate for adjusted earnings remains at 13 percent based on expected jurisdictional earnings mix for the full year and other non-recurring U.S. GAAP items.

Outlook

"Our businesses responded dynamically to demand conditions that rapidly deteriorated across the third quarter in Europe and, to a lesser extent, Asia," said Lori Ryerkerk. "Current order books validate our belief that the remainder of 2022 and the start of 2023 will be challenged by typical winter seasonality in addition to continued demand weakness in certain end-markets and customer destocking. Amid these dynamics, we are taking a series of controllable actions across our global supply chain to deliver fourth quarter adjusted earnings per share of $1.50 to $2.00, inclusive of the currently expected impact from the M&M acquisition in November and December, and to simultaneously prepare for recovery as we progress beyond the first part of 2023. We are committed as an organization to maximizing the earnings and cash generation of our businesses, integrating and synergizing M&M, and executing against our deleveraging plan."

A reconciliation of forecasted adjusted earnings per share to U.S. GAAP diluted earnings per share is not available without unreasonable efforts because a forecast of Certain Items, such as mark-to-market pension gains/losses, is not practical. For more information, see "Non-GAAP Financial Measures" below.

The Company's prepared remarks related to the third quarter will be posted on its website at investors.celanese.com under Financial Information/Financial Document Library on November 3, 2022. Information about Non-US GAAP measures is included in a Non-US GAAP Financial Measures and Supplemental Information document posted on our investor relations website under Financial Information/Non-GAAP Financial Measures.

Non-GAAP Financial Measures

Presentation

This document presents the Company's three business segments, Engineered Materials, Acetate Tow and Acetyl Chain.

Use of Non-US GAAP Financial Information

This release uses the following Non-US GAAP measures: adjusted EBIT, adjusted EBIT margin, operating EBITDA, adjusted earnings per share and free cash flow. These measures are not recognized in accordance with US GAAP and should not be viewed as an alternative to US GAAP measures of performance or liquidity. The most directly comparable financial measure presented in accordance with US GAAP in our consolidated financial statements for adjusted EBIT and operating EBITDA is net earnings (loss) attributable to Celanese Corporation; for adjusted EBIT margin is operating margin; for adjusted earnings per share is earnings (loss) from continuing operations attributable to Celanese Corporation per common share-diluted; and for free cash flow is net cash provided by (used in) operations.

Definitions of Non-US GAAP Financial Measures

• Adjusted EBIT is a performance measure used by the Company and is defined by the Company as net earnings (loss) attributable to Celanese Corporation, plus (earnings) loss from discontinued operations, less interest income, plus interest expense, plus refinancing expense and taxes, and further adjusted for Certain Items (refer to Table 8 of our Non-US GAAP Financial Measures and Supplemental Information document). We do not provide reconciliations for adjusted EBIT on a forward-looking basis (including those contained in this document) when we are unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the timing and amount of Certain Items, such as mark-to-market pension gains and losses, that have not yet occurred, are out of our control and/or cannot be reasonably predicted. For the same reasons, we are unable to address the probable significance of the unavailable information. Adjusted EBIT margin is defined by the Company as adjusted EBIT divided by net sales.

• Operating EBITDA is a performance measure used by the Company and is defined by the Company as net earnings (loss) attributable to Celanese Corporation, plus (earnings) loss from discontinued operations, less interest income, plus interest expense, plus refinancing expense, taxes and depreciation and amortization, and further adjusted for Certain Items, which Certain Items include accelerated depreciation and amortization expense. Operating EBITDA is equal to adjusted EBIT plus depreciation and amortization.

• Adjusted earnings per share is a performance measure used by the Company and is defined by the Company as earnings (loss) from continuing operations attributable to Celanese Corporation, adjusted for income tax (provision) benefit, Certain Items, and refinancing and related expenses, divided by the number of basic common shares and dilutive restricted stock units and stock options calculated using the treasury method. We do not provide reconciliations for adjusted earnings per share on a forward-looking basis (including those contained in this document) when we are unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the timing and amount of Certain Items, such as mark-to-market pension gains and losses, that have not yet occurred, are out of our control and/or cannot be reasonably predicted. For the same reasons, we are unable to address the probable significance of the unavailable information.

Note: The income tax expense (benefit) on Certain Items ("Non-GAAP adjustments") is determined using the applicable rates in the taxing jurisdictions in which the Non-GAAP adjustments occurred and includes both current and deferred income tax expense (benefit). 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 and related costs, where applicable, and specifically excludes changes in uncertain tax positions, discrete recognition of GAAP items on a quarterly basis, other pre-tax items adjusted out of our GAAP earnings for adjusted earnings per share purposes and changes in management's assessments regarding the ability to realize deferred tax assets for GAAP. In determining the adjusted earnings per share tax rate, we reflect the impact of foreign tax credits when utilized, or expected to be utilized, absent discrete events impacting the timing of foreign tax credit utilization. We analyze this rate quarterly and adjust it 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 actual tax rate used for GAAP reporting in any given reporting period. Table 3a of our Non-US GAAP Financial Measures and Supplemental Information document summarizes the reconciliation of our estimated GAAP effective tax rate to the adjusted tax rate. The estimated GAAP rate excludes discrete recognition of GAAP items due to our inability to forecast such items. As part of the year-end reconciliation, we will update the reconciliation of the GAAP effective tax rate to the adjusted tax rate for actual results.

• Free cash flow is a liquidity measure used by the Company and is defined by the Company as cash flow from operations, less capital expenditures on property, plant and equipment, and adjusted for capital contributions from or distributions to Mitsui & Co., Ltd. ("Mitsui") related to our methanol joint venture, Fairway Methanol LLC ("Fairway").

Non-US GAAP Financial Measures and Supplemental Information

November 3, 2022

In this document, the terms the "Company," "we" and "our" refer to Celanese Corporation and its subsidiaries on a consolidated basis.

Purpose

The purpose of this document is to provide information of interest to investors, analysts and other parties including supplemental financial information and reconciliations and other information concerning our use of non-US GAAP financial measures. This document is updated quarterly.

Presentation

This document presents the Company's three business segments, Engineered Materials, Acetate Tow and Acetyl Chain.

Use of Non-US GAAP Financial Measures

From time to time, management may publicly disclose certain numerical "non-GAAP financial measures" in the course of our earnings releases, financial presentations, earnings conference calls, investor and analyst meetings and otherwise. For these purposes, the Securities and Exchange Commission ("SEC") defines a "non-GAAP financial measure" as a numerical measure of historical or future financial performance, financial position or cash flows that excludes amounts, or is subject to adjustments that effectively exclude amounts, included in the most directly comparable measure calculated and presented in accordance with US GAAP, and vice versa for measures that include amounts, or are subject to adjustments that effectively include amounts, that are excluded from the most directly comparable US GAAP measure so calculated and presented. For these purposes, "GAAP" refers to generally accepted accounting principles in the United States.

Non-GAAP financial measures disclosed by management are provided as additional information to investors, analysts and other parties because the Company believes them to be important supplemental measures for assessing our financial and operating results and as a means to evaluate our financial condition and period-to-period comparisons. These non-GAAP financial measures should be viewed as supplemental to, and should not be considered in isolation or as alternatives to, net earnings (loss), operating profit (loss), operating margin, cash flow from operating activities (together with cash flow from investing and financing activities), earnings per share or any other US GAAP financial measure. These non-GAAP financial measures should be considered within the context of our complete audited and unaudited financial results for the given period, which are available on the Financial Information/Financial Document Library page of our website, investors.celanese.com. The definition and method of calculation of the non-GAAP financial measures used herein may be different from other companies' methods for calculating measures with the same or similar titles. Investors, analysts and other parties should understand how another company calculates such non-GAAP financial measures before comparing the other company's non-GAAP financial measures to any of our own. These non-GAAP financial measures may not be indicative of the historical operating results of the Company nor are they intended to be predictive or projections of future results.

Pursuant to the requirements of SEC Regulation G, whenever we refer to a non-GAAP financial measure, we will also present in this document, in the presentation itself or on a Form 8-K in connection with the presentation on the Financial Information/Financial Document Library page of our website, investors.celanese.com, to the extent practicable, the most directly comparable financial measure calculated and presented in accordance with GAAP, along with a reconciliation of the differences between the non-GAAP financial measure we reference and such comparable GAAP financial measure.

This document includes definitions and reconciliations of non-GAAP financial measures used from time to time by the Company.

Specific Measures Used

This document provides information about the following non-GAAP measures: adjusted EBIT, adjusted EBIT margin, operating EBITDA, operating EBITDA margin, operating profit (loss) attributable to Celanese Corporation, adjusted earnings per share, net debt, free cash flow and return on invested capital (adjusted). The most directly comparable financial measure presented in accordance with US GAAP in our consolidated financial statements for adjusted EBIT and operating EBITDA is net earnings (loss) attributable to Celanese Corporation; for adjusted EBIT margin and operating EBITDA margin is operating margin; for operating profit (loss) attributable to Celanese Corporation is operating profit (loss); for adjusted earnings per share is earnings (loss) from continuing operations attributable to Celanese Corporation per common share-diluted; for net debt is total debt; for free cash flow is net cash provided by (used in) operations; and for return on invested capital (adjusted) is net earnings (loss) attributable to Celanese Corporation divided by the sum of the average of beginning and end of the year short- and long-term debt and Celanese Corporation stockholders' equity.

Definitions

• Adjusted EBIT is a performance measure used by the Company and is defined by the Company as net earnings (loss) attributable to Celanese Corporation, plus (earnings) loss from discontinued operations, less interest income, plus interest expense, plus refinancing expense and taxes, and further adjusted for Certain Items (refer to Table 8). We believe that adjusted EBIT provides transparent and useful information to management, investors, analysts and other parties in evaluating and assessing our primary operating results from period-to-period after removing the impact of unusual, non-operational or restructuring-related activities that affect comparability. Our management recognizes that adjusted EBIT has inherent limitations because of the excluded items. Adjusted EBIT is one of the measures management uses for planning and budgeting, monitoring and evaluating financial and operating results and as a performance metric in the Company's incentive compensation plan. We do not provide reconciliations for adjusted EBIT on a forward-looking basis (including those contained in this document) when we are unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the timing and amount of Certain Items, such as mark-to-market pension gains and losses, that have not yet occurred, are out of our control and/or cannot be reasonably predicted. For the same reasons, we are unable to address the probable significance of the unavailable information. Adjusted EBIT margin is defined by the Company as adjusted EBIT divided by net sales. Adjusted EBIT margin has the same uses and limitations as Adjusted EBIT.

• Operating EBITDA is a performance measure used by the Company and is defined by the Company as net earnings (loss) attributable to Celanese Corporation, plus (earnings) loss from discontinued operations, less interest income, plus interest expense, plus refinancing expense, taxes and depreciation and amortization, and further adjusted for Certain Items, which Certain Items include accelerated depreciation and amortization expense. Operating EBITDA is equal to adjusted EBIT plus depreciation and amortization. We believe that Operating EBITDA provides transparent and useful information to investors, analysts and other parties in evaluating our operating performance relative to our peer companies. Operating EBITDA margin is defined by the Company as Operating EBITDA divided by net sales. Operating EBITDA margin has the same uses and limitations as Operating EBITDA.

• Operating profit (loss) attributable to Celanese Corporation is defined by the Company as operating profit (loss), less earnings (loss) attributable to noncontrolling interests ("NCI"). We believe that operating profit (loss) attributable to Celanese Corporation provides transparent and useful information to management, investors, analysts and other parties in evaluating our core operational performance. Operating margin attributable to Celanese Corporation is defined by the Company as operating profit (loss) attributable to Celanese Corporation divided by net sales. Operating margin attributable to Celanese Corporation has the same uses and limitations as Operating profit (loss) attributable to Celanese Corporation.

• Adjusted earnings per share is a performance measure used by the Company and is defined by the Company as earnings (loss) from continuing operations attributable to Celanese Corporation, adjusted for income tax (provision) benefit, Certain Items, and refinancing and related expenses, divided by the number of basic common shares and dilutive restricted stock units and stock options calculated using the treasury method. We believe that adjusted earnings per share provides transparent and useful information to management, investors, analysts and other parties in evaluating and assessing our primary operating results from period-to-period after removing the impact of the above stated items that affect comparability and as a performance metric in the Company's incentive compensation plan. We do not provide reconciliations for adjusted earnings per share on a forward-looking basis (including those contained in this document) when we are unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the timing and amount of Certain Items, such as mark-to-market pension gains and losses, that have not yet occurred, are out of our control and/or cannot be reasonably predicted. For the same reasons, we are unable to address the probable significance of the unavailable information.
  
  Note: The income tax expense (benefit) on Certain Items ("Non-GAAP adjustments") is determined using the applicable rates in the taxing jurisdictions in which the Non-GAAP adjustments occurred and includes both current and deferred income tax expense (benefit). 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 and related costs, where applicable, and specifically excludes changes in uncertain tax positions, discrete recognition of GAAP items on a quarterly basis, other pre-tax items adjusted out of our GAAP earnings for adjusted earnings per share purposes and changes in management's assessments regarding the ability to realize deferred tax assets for GAAP. In determining the adjusted earnings per share tax rate, we reflect the impact of foreign tax credits when utilized, or expected to be utilized, absent discrete events impacting the timing of foreign tax credit utilization. We analyze this rate quarterly and adjust it 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 actual tax rate used for GAAP reporting in any given reporting period. Table 3a summarizes the reconciliation of our estimated GAAP effective tax rate to the adjusted tax rate. The estimated GAAP rate excludes discrete recognition of GAAP items due to our inability to forecast such items. As part of the year-end reconciliation, we will update the reconciliation of the GAAP effective tax rate to the adjusted tax rate for actual results.

• Free cash flow is a liquidity measure used by the Company and is defined by the Company as net cash provided by (used in) operations, less capital expenditures on property, plant and equipment, and adjusted for capital contributions from or distributions to Mitsui & Co., Ltd. ("Mitsui") related to our methanol joint venture, Fairway Methanol LLC ("Fairway"). We believe that free cash flow provides useful information to management, investors, analysts and other parties in evaluating the Company's liquidity and credit quality assessment because it provides an indication of the long-term cash generating ability of our business. Although we use free cash flow as a measure to assess the liquidity generated by our business, the use of free cash flow has important limitations, including that free cash flow does not reflect the cash requirements necessary to service our indebtedness, lease obligations, unconditional purchase obligations or pension and postretirement funding obligations. Free cash flow is not a measure of cash available for discretionary expenditures since the Company has certain debt service and finance lease payments that are not deducted from that measure.

• Net debt is defined by the Company as total debt less cash and cash equivalents. We believe that net debt provides useful information to management, investors, analysts and other parties in evaluating changes to the Company's capital structure and credit quality assessment.

• Return on invested capital (adjusted) is defined by the Company as adjusted EBIT, tax effected using the adjusted tax rate, divided by the sum of the average of beginning and end of the year short- and long-term debt and Celanese Corporation stockholders' equity. We believe that return on invested capital (adjusted) provides useful information to management, investors, analysts and other parties in order to assess our income generation from the point of view of our stockholders and creditors who provide us with capital in the form of equity and debt and whether capital invested in the Company yields competitive returns.

Supplemental Information

Supplemental Information we believe to be of interest to investors, analysts and other parties includes the following:

• Net sales for each of our business segments and the percentage increase or decrease in net sales attributable to price, volume, currency and other factors for each of our business segments.

• Cash dividends received from our equity investments.

• For those consolidated ventures in which the Company owns or is exposed to less than 100% of the economics, the outside stockholders' interests are shown as NCI. Beginning in 2014, this includes Fairway for which the Company's ownership percentage is 50%. Amounts referred to as "attributable to Celanese Corporation" are net of any applicable NCI.

Results Unaudited

The results in this document, 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.
