Celanese Corporation (NYSE:CE), a global chemical and specialty materials company, today reported third quarter 2023 GAAP diluted earnings per share of $8.70 and adjusted earnings per share of $2.50. The Company generated net sales of $2.7 billion in the quarter, a decrease of 3 percent from the prior quarter, reflecting a sequential decrease in pricing of 3 percent partially offset by a sequential increase in volume of 1 percent. Celanese reported third quarter consolidated operating profit of $842 million, adjusted EBIT of $451 million, and operating EBITDA of $624 million, at margins of 31, 17, and 23 percent, respectively. The Company has delivered sequential increases in these profitability metrics across each of the last three quarters.

The difference between GAAP diluted earnings per share and adjusted earnings per share in the third quarter was primarily due to Certain Items totaling $438 million, including the gain from the formation of the Nutrinova joint venture (JV) and M&A-related costs, as well as a recorded income tax benefit of $236 million, primarily due to internal relocations of intellectual property to align with acquired operations.

Celanese took actions to reduce costs, align production and inventory levels with demand, and maximize cash generation in response to unfavorable demand and competitive dynamics. As a result, the Company:

Reduced inventory balances by $177 million in the third quarter with inventory reductions across Engineered Materials and the Acetyl Chain of 7 percent and 6 percent, respectively;

Generated third quarter operating cash flow of $403 million and free cash flow of $268 million; and

Reduced net debt by $758 million in the third quarter, including a $697 million sequential decrease in debt and a $61 million sequential increase in cash.

"Our third quarter performance is a reflection of our commitment to take the necessary actions to support our earnings growth and deleveraging plan in what has been a persistently challenging backdrop this year," said Lori Ryerkerk, chair and chief executive officer. "We continued to lift the earnings power of Celanese and significantly strengthened our balance sheet position in the third quarter. Across the first three quarters of 2023 we have reduced our net debt by $829 million and remain well on path to meaningfully exceed the full year objective to reduce net debt by $1 billion in 2023."

Recent Highlights:

Announced a series of transactions to extend the Company's debt maturity profile and lower the total effective net borrowing rate to the Company. The total value of the combined 2023, 2024, and 2025 debt maturities was significantly reduced, effectively eliminating the need to refinance any debt over the next several years.

Completed the formation of Nutrinova, a Food Ingredients JV with Mitsui & Co., Ltd.,. Celanese contributed the assets, technology, and employees of its Food Ingredients business of which Mitsui acquired a 70 percent stake at a purchase price of $503 million, including closing adjustments.

Announced the planned closure of the Company's nylon 66 (PA66) and high-performance nylon (HPN) polymerization units in Uentrop, Germany. Polymerization costs at Uentrop are the highest in the Celanese global nylon network due to energy and raw material costs in the region. The Company plans to cease PA66 and HPN polymerization at Uentrop by January 1, 2024 and February 1, 2024, respectively.

Ceased production at Engineered Materials production facilities in Campo Bom, Brazil; Berazategui, Argentina; and Wehr, Germany in September and October.

Third Quarter 2023 Business Segment Overview

Acetyl Chain

The Acetyl Chain delivered third quarter net sales of $1.2 billion, a 1 percent decrease from the prior quarter. Third quarter volume increased by 3 percent sequentially, and pricing decreased by 3 percent sequentially and 18 percent year over year as a result of lower global industry utilization, particularly in the Western Hemisphere. The business navigated weakened pricing conditions by utilizing its commercial and supply chain optionality. Amid disruptions in acetic acid industry supply in China, the business pivoted to secure 48 percent more sequential acetic acid volume in China and captured a disproportionate share of pricing strength at the end of the third quarter. The business continued to flex its production network to align with demand, including idling the Frankfurt VAM facility for the duration of the quarter, to deliver further inventory reductions. As a result of these actions, the Acetyl Chain delivered third quarter operating profit of $272 million, adjusted EBIT of $310 million, and operating EBITDA of $365 million at margins of 22, 25, and 30 percent, respectively. The Acetyl Chain limited the sequential decline in each of these profit metrics to approximately $20 million, despite a series of sequential headwinds including margin compression in Europe, a spike in U.S. Gulf Coast electricity costs, and an unfavorable earnings impact related to inventory. In a global demand environment that remains challenged, the Acetyl Chain has demonstrated the stability and resilience of its foundational earnings across each quarter of 2023.

Engineered Materials

Engineered Materials reported third quarter net sales of $1.5 billion, a sequential decrease of 4 percent. Sequential volume declined by 1 percent as the impact of poor demand conditions across most end-markets was partially offset by sequential volume growth in automotive and medical. Third quarter pricing decreased by 3 percent sequentially as a result of challenging competitive dynamics across the year due to poor demand and raw material deflation. The business offset the impact of pricing and volume decreases by reducing costs, aligning production and inventory levels to demand, and pivoting to end-markets with relative demand strength. Engineered Materials reduced inventory by approximately $140 million across the third quarter and has delivered inventory reductions across the first three quarters of 2023 approaching $400 million. Engineered Materials delivered third quarter operating profit of $691 million, adjusted EBIT of $229 million, and operating EBITDA of $340 million at margins of 45, 15, and 22 percent, respectively. Sequential increases in these earnings metrics was supported by increased earnings contributions from Mobility & Materials (M&M) driven by volume growth and incremental synergies. Affiliate earnings decreased by $10 million sequentially, primarily driven by M&M-related affiliates.

Cash Flow and Tax

Celanese reported third quarter operating cash flow of $403 million and free cash flow of $268 million which included cash capital expenditures of $131 million. Celanese returned $76 million in cash to shareholders via dividends in the quarter.

The effective income tax rate was a benefit of 33 percent for the third quarter compared to an expense of 40 percent for the same quarter in 2022. The lower effective rate was primarily due to the relocation of certain intangible assets to align with the acquired M&M foreign operations, differences in the tax and U.S. GAAP gain from the formation of the Nutrinova JV, decreased earnings in high taxed jurisdictions related to current demand conditions, and a decrease in valuation allowances on U.S. foreign tax credit carryforwards due to revised forecasts of foreign sourced income and expenses during the carryforward period. The effective tax rate for 2023 adjusted earnings was revised to 9 percent based on the expected jurisdictional earnings mix for the full year and consideration of other non-recurring U.S. GAAP items.

Outlook

"Our focus remains on sustainably lifting the earnings power of Celanese by taking decisive actions to control what we can in an operating environment that remains volatile and uncertain," said Lori Ryerkerk. "Through the organizational, production footprint, and commercial actions we take, we are supporting near-term performance and laying the groundwork for amplified earnings growth when demand returns. We are hard at work to deliver sequential growth in the earnings contributions from our businesses in the fourth quarter, despite anticipated cold weather seasonality, and to position ourselves to enter 2024 with additional momentum."

Reflective of controllable actions, improvement in destocking conditions, and typical cold weather seasonality, the Company anticipates fourth quarter adjusted earnings per share of $2.10 to $2.50, inclusive of approximately $0.30 per share of M&M transaction amortization. Consequently, Celanese anticipates full year adjusted earnings per share at the lower-end of the previous $9.00 to $10.00 range, inclusive of approximately $1.20 per share of M&M transaction amortization.

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 third quarter will be posted on its website at investors.celanese.com under Financial Information/Financial Document Library on November 6, 2023. 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 November 6, 2023 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

November 6, 2023

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 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 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 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. Amounts referred to as "attributable to Celanese Corporation" are net of any applicable NCI.
