Celanese Corporation Reports Full Year 2022 and Fourth Quarter Earnings

Celanese Corporation (NYSE: CE), a global chemical and specialty materials company, today reported highest-ever GAAP diluted earnings per share of $17.41 and second-highest ever adjusted earnings per share of $15.88 for full year 2022. The Company generated record net sales of $9.7 billion in the year, an increase of 13 percent over the prior record set in 2021. Full year net sales reflected increases in pricing and volume of 11 percent and 6 percent over 2021, respectively. The Company delivered year over year pricing growth and productivity across both business segments to largely offset over $1.2 billion in raw material, energy, and supply chain cost inflation over 2021. As a result, the Company reported 2022 consolidated operating profit of $1.4 billion and adjusted EBIT of $2.2 billion. During the year, the Company generated record operating cash flow of $1.8 billion and free cash flow of $1.3 billion. Celanese returned $297 million in cash to shareholders via dividends in 2022.

On November 1, 2022, the Company successfully completed the acquisition of the Mobility & Materials (M&M) business of DuPont, 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. Full year 2022 financial results reflect the contribution of M&M performance in November and December.

The difference between GAAP diluted earnings per share and adjusted earnings per share for 2022 was primarily due to an income tax provision for U.S. GAAP that was a benefit for full year 2022 as a result of non-recurring internal restructuring transactions related to the M&M acquisition. The impact of the beneficial tax recognition more than offset the impact of costs related to the M&M acquisition, including approximately $267 million in M&A-related costs, and $158 million in net interest expense incurred prior to transaction closing and certain fees related to debt issued.

Celanese also reported fourth quarter GAAP diluted earnings per share of $7.03 and adjusted earnings per share of $1.44. The Company generated operating cash flow of $541 million and free cash flow of $395 million in the quarter.

"Our team delivered resilient performance despite an exceptionally challenging end to 2022 including accelerated destocking, poor sequential demand in Asia due to COVID, challenging competitive dynamics in Europe, and the impact of Winter Storm Elliott," said Lori Ryerkerk, chair and chief executive officer. "Our 2022 adjusted earnings per share performance was within 12 percent of our all-time high delivered in 2021 and 44 percent higher than our next best year. Despite the impact of elevated volatility across a number of external dynamics, our Celanese team continues to execute our business models and demonstrate a long-term underlying lift in the earnings power of the company."

Fourth Quarter 2022 Financial Highlights:

Recent Highlights:

• Completed the acquisition of Mobility & Materials on November 1, 2022.

• Announced the signing of a term sheet to form a standalone Food Ingredients joint venture (JV) in which Celanese will contribute its Food Ingredients business and Mitsui will acquire a 70 percent stake. The transaction is expected to close in the third quarter and cash proceeds will be used to pay down debt.

• Completed a strategic overhaul of the acetate flake and tow products as part of the Acetyl Chain which is expected to deliver significant margin expansion in those products in 2023.

• Completed an ultra-low capital project, at the EVA facility in Edmonton, to repurpose existing manufacturing and infrastructure assets and unlock approximately 35 percent incremental capacity to meet strong demand growth.

Full Year 2022 and Fourth Quarter Business Segment Overview

Acetyl Chain

The Acetyl Chain reported 2022 net sales of $5.7 billion, a 3 percent decrease from record net sales set in the prior year. Full year net sales reflected a 6 percent increase in pricing, 6 percent decrease in volume, and 3 percent unfavorable impact from foreign currency. As a result of commercial pricing actions, the business offset the majority of approximately $650 million in raw material, energy, and supply chain cost inflation over the prior year. In the first half of 2022, the Acetyl Chain maintained volumes across its global network by pivoting volume from Asia to incremental demand and margin in the Western Hemisphere. In the second half of the year, weaker fundamental demand was amplified by destocking, particularly across Europe and China and the Acetyl Chain took decisive actions to reduce cost and align its production to market demand. The Frankfurt VAM unit, the highest-cost facility in its global VAM network, was idled for the majority of the second half of 2022. Additionally, the Acetyl Chain intentionally idled all five of its major production units in China at different points in the fourth quarter. As a result, the Acetyl Chain generated GAAP operating profit of $1.4 billion and adjusted EBIT of $1.6 billion, at margins of 25 and 28 percent, respectively. The 2022 results reflect a resegmentation of the former Acetate Tow reporting segment into the Acetyl Chain due to the successful completion of the strategic overhaul of that business as a derivative of acetic acid.

The Acetyl Chain delivered fourth quarter net sales of $1.1 billion due to sequential pricing and volume declines of 10 percent and 9 percent, respectively. In the last two weeks of the quarter, the business proactively shut down its U.S. Gulf Coast production network in anticipation of Winter Storm Elliott, resulting in over 130 kt of lost production in addition to supply chain disruptions. Despite these challenges, the Acetyl Chain delivered fourth quarter GAAP operating profit of $204 million and adjusted EBIT of $242 million, in the upper half of the guidance range provided.

Engineered Materials

Engineered Materials delivered record net sales of $4.0 billion in 2022, a 48 percent increase over the prior year. Net sales was driven by volume and price increases of 33 percent and 23 percent, respectively, and an 8 percent unfavorable impact from foreign currency. Organic volume growth in the automotive, electronics, and medical end-markets as well as volume contributions from the Santoprene and M&M acquisitions offset the impact of underlying demand softness and destocking in the second half of the year. The Santoprene acquisition, which closed in the fourth quarter of 2021, contributed across the full year. The M&M acquisition, which closed on November 1, 2022, contributed in the last two months of 2022. Pricing across 2022 expanded significantly as a result of broad commercial initiatives, including the implementation of an energy surcharge, to mitigate nearly $600 million in raw material, energy, and supply chain cost inflation. Enhanced product mix also elevated pricing, due in part to the medical implant business returning to a pre-COVID condition in the second half of the year. Engineered Materials delivered 2022 GAAP operating profit of $429 million and adjusted EBIT of $779 million. The difference between GAAP operating profit and adjusted EBIT was due primarily to costs associated with the acquisition of M&M. Affiliate earnings contributed $202 million during the year.

Engineered Materials reported fourth quarter net sales of $1.2 billion due to a sequential volume increase of 34 percent and pricing decrease of 1 percent. Volume increased sequentially due to the impact of the M&M acquisition which was partially offset by seasonality and broad destocking. Pricing decreased as the impact of a lower energy surcharge and challenging competitive dynamics in Europe more than offset the impact of improved mix. Engineered Materials reported fourth quarter GAAP operating profit of $25 million and adjusted EBIT of $138 million which included affiliate earnings of $31 million.

Cash Flow and Tax

Celanese generated full year 2022 operating cash flow of $1.8 billion and free cash flow of $1.3 billion. Capital expenditures across the year were $543 million. Celanese returned $297 million in cash to shareholders via dividends in the year.

The tax rate for U.S. GAAP purposes was a benefit of (34) percent for full year 2022 due to deferred tax benefits related to non-recurring internal restructuring transactions related to the M&M acquisition, to centralize ownership of intellectual property with the business, and to facilitate future deployment of cash to service acquisition indebtedness. The effective tax rate for adjusted earnings was 13 percent for 2022 as certain benefits of the internal restructuring will be realized in future periods.

Outlook

"Our March order books reflect improvement in many of the recent external challenges we have seen, and we are taking action to address those which still persist," said Lori Ryerkerk. "We are confident that the back half of the first quarter will represent an inflection point and that sequential earnings improvement across our businesses will drive anticipated first quarter adjusted earnings per share of $1.50 to $1.75, inclusive of approximately $0.30 per share of M&M transaction amortization¹. We expect an upward trajectory in our quarterly earnings across 2023 as a result of demand improvement reflected in our current order books, enhancements to our businesses, and M&M synergies."

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 fourth quarter will be posted on its website at investors.celanese.com under Financial Information/Financial Document Library on February 23, 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, 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

February 23, 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 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.
