Celanese Corporation (NYSE: CE), a global chemical and specialty materials company, today reported second quarter 2024 U.S. GAAP diluted earnings per share of $1.42 and adjusted earnings per share of $2.38. The Company generated net sales of $2.7 billion in the quarter, an increase of 2 percent from the prior quarter, reflecting a sequential increase in volume of 4 percent and sequential decrease in pricing of 2 percent.

Celanese continued to focus on execution of its controllable action plan, including driving volume growth through the project pipeline model, lowering costs through reduction of capacity in high-cost locations, and improving business efficiency through the integration of the acquired Mobility & Materials (M&M) businesses into a single SAP ERP system. These actions were especially impactful during a quarter that presented significant external headwinds. Among these headwinds were a series of outages and curtailments from multiple suppliers that led to the Company's declaration of force majeure for acetic acid and VAM sold in the Western Hemisphere, as well as persistent poor demand conditions across many of the Company's end-markets. Against the backdrop of these headwinds, the results reflect meaningful realization of business improvements from the execution of the Company's action plans. Celanese reported second quarter operating profit of $250 million, adjusted EBIT of $451 million, and operating EBITDA of $632 million at margins of 9, 17, and 24 percent, respectively.

The difference between U.S. GAAP diluted earnings per share and adjusted earnings per share in the second quarter was primarily due to Certain Items totaling $102 million.¹

"In the second quarter, we delivered a double-digit sequential expansion of adjusted EBIT in spite of some of the most severe external challenges we've faced in many years," said Lori Ryerkerk, chair and chief executive officer. "The prolonged weak demand environment we have continued to experience over the past several quarters was compounded by multiple supplier failures that led us to declare force majeure for acetic acid and VAM sold in the Western Hemisphere. In this environment, we stayed focused on delivering on our action plan, which resulted in the highest ever contribution from the Engineered Materials business in our history. This highlights the importance of our execution focus, and I thank our teams for their resilience and agility to achieve these results."

Second Quarter Business Segment Overview

Acetyl Chain

The Acetyl Chain delivered second quarter net sales of $1.2 billion, a 5 percent decrease from the prior quarter. Volume decreased by 1 percent sequentially due to the effects of the force majeure, delayed timing of opportunistic spot sales, and muted seasonal improvements. Second quarter pricing across the Acetyl Chain decreased by 4 percent sequentially. The multiple supplier outages and curtailments had a significant impact on the ability of Celanese to produce at the Clear Lake site, the Company's lowest cost and lowest carbon footprint acetic acid unit. The second quarter total losses of Clear Lake acetic acid attributable to unplanned supplier disruptions was the highest in over 15 years. In the face of these headwinds, the Acetyl Chain worked to assure virtually all customer needs were met. The business delivered second quarter operating profit of $242 million, adjusted EBIT of $277 million, and operating EBITDA of $338 million at margins of 20, 23, and 28 percent, respectively. The Acetyl Chain has continued to exercise the unique optionality of the business model in the face of chronic low demand. The flexibility of the model allowed the business to expand volumes in downstream markets in Asia, despite poor demand conditions, by pivoting to alternate applications with available demand. The Acetyl Chain will continue to leverage this optionality to optimize outcomes through the extended demand trough.

Engineered Materials

Engineered Materials reported second quarter net sales of $1.5 billion, representing a sequential increase of 6 percent. Sequential growth was driven by a 7 percent increase in volume and stable pricing, partially offset by a small currency impact. The breadth of volume growth was widespread across the portfolio, with all 10 of the largest polymer families achieving sequential growth. This was further bolstered by a favorable mix, primarily in higher margin products and applications like Vamac® and medical implants, contributing to the overall volume increase and demonstrating the effectiveness of the project pipeline model. Engineered Materials delivered second quarter operating profit of $138 million, record adjusted EBIT of $265 million, and record operating EBITDA of $375 million. These figures represent margins of 9, 18, and 26 percent, respectively with sequential earnings improvements of 55, 32, and 24 percent. In addition to the volume growth, the sequential improvement in earnings was driven by incremental synergies and the realization of lower raw material costs. Synergy capture in the quarter included initial earnings contributions from previous initiatives such as the closure of nylon 6,6 polymerization in Uentrop, Germany. For the second consecutive quarter, these strategic actions have lifted the performance of the former M&M product portfolio to deliver the highest quarterly contribution since the acquisition.

Cash Flow and Tax

Celanese reported second quarter operating cash flow of $292 million and free cash flow of $173 million, which included cash capital expenditures of $105 million. Celanese returned $77 million in cash to shareholders via dividends in the quarter. The Company repaid a bond of approximately $500 million that matured in the second quarter as part of its deleveraging plan.

The effective U.S. GAAP income tax rate was an expense of 16 percent for the second quarter compared to a benefit of 2 percent for the same quarter in 2023. The effective income tax rate for the current year was higher compared to the same period in 2023, primarily due to current year tax effects related to internal debt restructuring transactions, prior year non-recurring decreases in valuation allowances on U.S. foreign tax credit carryforwards due to changes in forecasted foreign sourced income and expenses during the carryforward period, and increased earnings in high-taxed jurisdictions related to improved economic conditions in the current year. The effective tax rate for adjusted earnings was 9 percent based on expected jurisdictional earnings mix for the full year and consideration of other non-recurring U.S. GAAP items.

Outlook

"We are encouraged to see the tangible realization of our value creation initiatives in our second quarter results, and we are confident that those benefits will continue through the year," said Lori Ryerkerk. "Given the continued lack of evidence of meaningful demand recovery and the increasing pricing pressure from this low demand environment, our focus will remain on what we can control to deliver a sustainable earnings lift for Celanese. We expect the third quarter will bring an easing of the effects of the force majeure, and further improvements to our business driven by our action plans. Because of our foundational value creation initiatives, I am confident we will continue to deliver improved earnings performance in the third quarter and through the remainder of the year."

The Company anticipates third quarter adjusted earnings per share of $2.75 to $3.00. Furthermore, based on the effects of the second quarter force majeure and persistent demand challenges, the Company anticipates full year adjusted earnings per share of $10.25 to $10.75.

Reconciliations of forecasted non-GAAP measures such as adjusted earnings per share, adjusted EBIT or free cash flow to the equivalent U.S. GAAP measures (diluted earnings per share, net earnings (loss) attributable to Celanese Corporation and net cash provided by (used in) operations, respectively), are not available without unreasonable efforts because a forecast of Certain Items, such as mark-to-market pension gains/losses, and other items is not practical. For more information, see "Non-GAAP Financial Measures" below.

The Company's prepared remarks related to the second quarter will be posted on its website at investors.celanese.com under Financial Information/Financial Document Library on August 1, 2024. 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 two business segments, Engineered Materials and the 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, operating EBITDA margin, 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 operating EBITDA 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. Operating EBITDA margin is defined by the Company as operating EBITDA divided by net sales.

• 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 net cash provided by (used in) operations, less capital expenditures on property, plant and equipment, and adjusted for contributions from or distributions to our noncontrolling interest joint ventures. We do not provide reconciliations for free cash flow 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 items such as working capital changes, fluctuations in foreign currency exchange rates, the impact and timing of potential acquisitions and divestitures, and other structural changes, 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.

Reconciliation of Non-US GAAP Financial Measures

Reconciliations of the Non-US GAAP financial measures used in this press release to the comparable US GAAP financial measure, together with information about the purposes and uses of Non-US GAAP financial measures, are included in our Non-US GAAP Financial Measures and Supplemental Information document filed as an exhibit to our Current Report on Form 8-K filed with the SEC on or about August 1, 2024 and also available on our website at investors.celanese.com under Financial Information/Financial Document Library.

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.

Supplemental Information

Additional information about our prior period performance is included in our Quarterly Reports on Form 10-Q and in our Non-US GAAP Financial Measures and Supplemental Information document.

Non-US GAAP Financial Measures and Supplemental Information

August 1, 2024

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 two business segments, Engineered Materials and the 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 shareholders' 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 contributions from or distributions to our NCI joint ventures. 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. We do not provide reconciliations for free cash flow on a forward-looking basis 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 items such as working capital changes, fluctuations in foreign currency exchange rates, the impact and timing of potential acquisitions and divestitures, and other structural changes, 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.

• 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 shareholders' 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 shareholders 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 shareholders' interests are shown as NCI. 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.
