**Scott Richardson, Celanese Corporation, President and Chief Executive Officer**

Celanese continues to take decisive actions to drive shareholder value by leveraging our unique capabilities. Our global footprint, diversified products, and broad end-market exposure enable strong execution and underscore the resilience of our businesses across a range of operating environments. As we move forward, we remain focused on advancing our strategic initiatives with speed and agility to support sustained value creation.

Today, we reported first quarter 2026 adjusted earnings per share of $0.85 (inclusive of approximately $0.36 per share of total Celanese transaction amortization<sup>1</sup>). Results were at the upper end of our expectations and reflect deliberate, intentional execution across both of our businesses. In Engineered Materials (EM), ongoing efforts to reposition the specialty portfolio toward higher growth, higher value end markets drove favorable mix, while the business continued to advance cost productivity initiatives. In

the Acetyl Chain (AC), teams acted swiftly to capture high value opportunities that emerged late in the first quarter. Collectively, these actions offset higher feedstock and energy costs across both businesses and established a stronger operating and earnings trajectory into the second quarter and through 2026.

Before discussing business performance further, let me turn to the broader global developments and the implications for our business. Late quarter supply chain dislocations created selective volume and pricing opportunities, which we acted decisively to capture. As the year unfolds, we expect to see continued opportunities to drive value across the business, even as higher input costs and continued weak end-market demand remain factors. The impacts of these dynamics are not likely to be uniform across our portfolio, differing between AC and EM, which I will address in our segment performance commentary.

During the first quarter, we executed a series of targeted steps to leverage the differentiated capabilities of our businesses, enhancing supply flexibility, mitigating cost pressures, and strengthening performance:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Successfully restarted the Frankfurt, Germany, VAM unit on an accelerated timeline. Security of supply has become a critical priority for customers amid ongoing geopolitical uncertainty. Leveraging the Frankfurt VAM asset enhances the optionality to respond to customer needs in a flexible manner.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Advanced actions to accelerate completion of the turnaround of the POM facility at Frankfurt and subsequent restart of the unit later in May.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Implemented immediate procurement actions to prioritize supply assurance of critical feedstocks, mitigate costs, and maintain logistics continuity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Announced targeted price increases in both EM and AC to offset raw material and supply chain cost escalations.

In parallel, we continued to advance structural initiatives designed to position Celanese for sustained value creation. These growth-oriented measures reflect a disciplined focus on enhancing competitiveness, durability, and customer alignment, while reinforcing the strong operational foundations already in place:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Announced a series of strategic initiatives within EM to reposition the nylon business to create a more resilient platform for the future. These actions are intended to strengthen competitiveness and simplify the manufacturing footprint, while prioritizing continuity of supply to customers. They include the planned closure of the nylon 6,6 polymerization unit in Sakra, Singapore in the third quarter and the optimization of our two nylon 6,6 polymerization facilities in North America,

------

which is expected to reduce overall polymer production. Collectively, we expect these nylon transition initiatives to deliver approximately $30 million of annualized cost savings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reaffirmed a set of complementary actions across the EM network to better align capabilities with heightened customer requirements and demand outlook, including advancing steps toward commencement of liquid crystal polymer-related operations in China, targeted upgrades of specialty compounds capability in Europe, introduction of new medical-grade compounding in Asia, and implementation of targeted product mix and localization enhancements in India.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Initiated the commissioning of a new VAE Emulsions reactor in Frankfurt to more efficiently meet customers' needs. This investment, which was part of previous years' capital expenditures, further strengthens our downstream capabilities and enhances the agility of the AC business in a dynamic operating environment.

These initiatives reflect the next milestones in the execution journey we have been on since early 2025. Together with other recently completed actions - including debt refinancing measures, the Micromax<sup>®</sup> divestiture, and the planned closure of the acetate tow facility in Lanaken, Belgium - these steps exemplify our increasing momentum in driving sustainable performance improvement across the company.

We expect these actions to deliver a meaningful earnings impact in 2026 and beyond. This improved earnings profile aims to strengthen cash generation this year and reinforces our continued commitment to deleveraging.

Now, let me turn to the specifics of our businesses.

Engineered Materials generated first quarter adjusted EBIT of $220 million and operating EBITDA of $324 million at margins of 17 and 25 percent, respectively. Net sales increased by 4 percent sequentially, mainly from seasonal volume improvement amid continued demand softness in certain end markets. EM's results reflected continued progress against strategic initiatives focused on pipeline quality and diversification to drive sales mix enhancement, value-based pricing, and cost reduction actions that are collectively strengthening the sustainable earnings power of the business.

The first quarter progressed largely as expected. Key end markets remained subdued, most notably Chinese automotive, while evolving global dynamics created modest cost headwinds late in the quarter. Against this continued soft demand backdrop, we offset input cost increases through disciplined execution. These actions included advancing progress toward our $30 to $50 million annual cost reduction

------

target and further strengthening pipeline quality to drive product and regional mix improvements, particularly in Europe.

EM continues to prioritize strengthening its core business fundamentals. The recently announced transition steps in nylon 6,6 represent the next phase of a broader, multi-year effort across regions to address network inefficiencies and unsustainable feedstock dynamics. Together with the complementary initiatives previously outlined, these steps reflect a deliberate reshaping of EM's operational footprint and capabilities to better align with evolving customer and end-market requirements. Collectively, they build upon prior initiatives to strengthen competitiveness and resilience, without compromising customer confidence, supply reliability, product quality, or our ability to innovate.

The nylon portfolio transition and other network actions are elements of EM's broader Grow and Fortify strategy, designed to sharpen our competitive position. The reconfiguration and simplification of the manufacturing footprint, coupled with structurally lower costs and streamlined inventory levels, further fortify the foundation. The overarching objective is to align enabling capabilities with end market segment strategies, better positioning the business to compete effectively and support long-term growth. This allows EM to drive higher quality growth through mix shift toward higher margin segments, improved pipeline quality and diversification, and disciplined commercial execution. The resulting portfolio mix, with greater exposure to higher-growth end markets such as electronics, data center server componentry, medical devices, and electric vehicles, creates durable and attractive growth vectors for the business.

Looking at the second quarter, we anticipate modest seasonal volume improvement, particularly in Asia, along with benefit from pricing measures and inventory builds to support the nylon transition. These factors are expected to be more than offset by headwinds from inventory drawdowns and incremental costs tied to the POM turnaround, the largest such effort for the EM business over the past five years. Based on these factors, we expect EM adjusted EBIT for the second quarter to be $190 to $210 million and operating EBITDA to be $290 to $310 million.

While ongoing end-market uncertainty limits visibility beyond the second quarter, we currently expect sequential moderation in EM earnings in the third quarter. Order patterns in April and May have been favorable, suggesting customers are increasingly prioritizing reliable suppliers. This dynamic may be driving some front-loading of orders, which could modestly impact the second half. Additionally, we expect results in the back half of the year to be affected by inventory drawdowns associated with the nylon transition and continued structural inventory reduction actions already underway, as well as the potential for sequential input cost pressures.

------

The EM team remains focused on execution and continues to pursue opportunities for cost reduction, pipeline growth, mix enrichment, and value-based pricing. Our continued investment in a resilient operational model is delivering measurable results and reinforces our commitment to disciplined execution of the Grow and Fortify strategy.

The Acetyl Chain delivered first quarter adjusted EBIT of $131 million and operating EBITDA of $194 million, at margins of 13 and 19 percent, respectively, as net sales increased sequentially by 10 percent. Results exceeded the high end of our guidance range, mainly due to late-quarter spot pricing opportunities, largely in China. These benefits were partially offset by higher input costs, particularly in Europe and Asia, along with continued weakness in acetate tow.

Consistent with last year, AC faced a $40 million sequential impact in the first quarter related to the timing of the acetate tow dividend, which is paid three times a year starting in the second quarter. Proactive pricing, volume capture, and actions to optimize the manufacturing network drove first quarter earnings above expectations, despite the headwinds. AC's timely actions late in the quarter enabled the capture of high-value opportunities while positioning the business for meaningful upside in the second quarter.

Recent global dynamics have elevated security of supply as a key priority for many customers, especially in Europe. AC's globally integrated business model provides the flexibility and scale needed to navigate such disruptions reliably and effectively. AC is structurally well-positioned to outperform as the current situation has reset trade flows and pricing in certain products, as well as customer behavior in favor of reliable supply.

Building on the highly differentiated network and operating flexibility, AC has taken several actions to capture value, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• As discussed earlier, restarted the Frankfurt VAM unit in about five weeks and initiated commissioning of the new Frankfurt VAE unit, enhancing downstream optionality.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Optimized utilization of cost-advantaged U.S. assets and dynamically refined the downstream reactor mix regionally in Asia.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Executed targeted pricing actions to offset feedstock inflation, while proactively managing feedstock and raw-material supply to minimize disruption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Initiated further footprint optimization through the intended closure of the esters unit in Singapore to right-size the network, improve efficiency by directing upstream molecules into higher-value downstream products, and deliver productivity savings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Advanced growth and pipeline innovation to capture share as customers prioritize reliable supply and initiated substitution opportunities versus crude-based competing systems.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Accelerated commercialization of sustainability-focused offerings, especially in coatings and adhesives.

Looking to the second quarter, we expect price increase realization across most of the AC portfolio. We anticipate that volume and price opportunities will more than offset sharp increases in feedstock costs, along with continued weakness in acetate tow. Additionally, the acetate tow dividend is set to resume in the second quarter, with the full-year dividend to be consistent with last year. Taking these factors into account, we expect second quarter adjusted EBIT of $300 to $325 million, and operating EBITDA of $360 to $385 million.

The current business environment for AC is best characterized as upstream supply tightness within a soft to stable demand backdrop. Most key end markets, including paints, coatings, and construction, remain sluggish across regions. We expect volume and pricing opportunities driven by supply dislocations to persist throughout the year with gradual moderation in the back half from second quarter levels. The AC team will continue to leverage the optionality and agility inherent in its daily operating model to capture opportunities across market conditions. In parallel, ongoing strategic initiatives are strengthening the foundation of the business and support durable future earnings growth. Strong execution amid evolving dynamics continues to validate the resilience, differentiation, and earnings power of the Acetyl Chain's fundamental business model.

**Chuck Kyrish, Celanese Corporation, Senior Vice President and Chief Financial Officer**

Our teams continued to execute on our strategic priorities in the first quarter, including driving free cash flow, reducing balance sheet leverage, closing a strategic divestiture, and maintaining strong liquidity - actions that further reinforce the strength of our financial position.

At the end of the first quarter, we had $1.8 billion in cash and an undrawn $1.75 billion revolving facility. The cash balance was bolstered by the completion of the Micromax<sup>®</sup> divestiture during the quarter. We currently hold a higher cash balance in preparation for the repayment of roughly $900 million in bonds that we plan to repay in the second and third quarter of this year. Given the relatively low coupon rates on these maturities and costs associated with prepayment, it is economically favorable to hold cash until the bonds can be paid at par in the following quarters. We remain confident in our current positioning to manage our near-term maturities.

Let me now provide an update on free cash flow performance. In the first quarter, we reported $3 million in free cash flow generation, despite normal seasonal headwinds and the working capital timing impacts that are typical for the first quarter. This is a strong relative performance considering that first quarter free cash flow has been a use of cash in each of the last few years.

Net cash interest was approximately $118 million in the first quarter. We expect this to represent the lowest quarterly net cash interest of the year, due to timing of coupon payments impacted by the fourth quarter refinancing transactions. Net cash interest payments for the full year are anticipated to be roughly $640 million. For the balance of the year, the quarterly payments are expected to be roughly $175 million, reflecting the progress we made last year in reducing the concentration of quarterly cash interest payments. Interest expense on the income statement will differ from the cash interest and is expected to be $690 million, for 2026.

Capital expenditures for the first quarter were $66 million, consistent with our targeted annual range of $300 to $350 million. We continue to harvest the strategic investments made over the past several years and anticipate our annual capital expenditures to remain within this range through our deleveraging phase. Our focus remains on safety, maintenance, regulatory compliance, and productivity projects, strengthening our ability to scale when demand conditions improve.

Working capital was a use of cash of approximately $96 million in the first quarter, consistent with normal seasonal patterns. Looking ahead over the next few quarters, we could see temporary headwinds in working capital driven by dynamics associated with the current business environment. Specifically, we

------

expect higher inventory values due to increases in raw material and energy costs, along with some potential timing impacts in accounts receivable.

For the full year, we expect the incremental earnings driven by actions already underway to translate into improved free cash flow across 2026 and 2027, with the timing depending on market conditions and the associated working capital dynamics, particularly in the fourth quarter. Considering these factors, as well as the strong performance in the first quarter, we are increasing our full-year 2026 free cash flow target to $700 to $800 million.

Turning to Other Activities, in the first quarter we reported a net expense of $76 million in adjusted EBIT and $63 million in operating EBITDA. For the full year of 2026, we anticipate an average quarterly net expense run rate of approximately $75 to $80 million in adjusted EBIT.

The effective tax rate for adjusted earnings was 8 percent for the first quarter and we anticipate this rate for 2026 based on expected jurisdictional earnings mix for the full year and consideration of other non-recurring U.S. GAAP items.

As Scott noted, we remain focused on our action plans and disciplined execution to strengthen our foundation, drive earnings, and position Celanese for sustained value creation. Strong execution on free cash flow generation and progress on strategic divestitures have enabled meaningful progress in net debt reduction, which remains our top priority. We remain committed to deleveraging through aggressive and prudent actions, ultimately enabling a wider range of capital allocation opportunities.

**Scott Richardson, Celanese Corporation, President and Chief Executive Officer**

In the second quarter, we expect sequential volume and price realization in the Acetyl Chain. We anticipate modest sequential pricing improvement in EM and seasonal volume growth across both businesses, partially offset by continued input cost pressures. Based on these dynamics, we expect second quarter adjusted earnings per share of approximately $2.00 to $2.40.

------

We currently expect favorable conditions to continue through the balance of 2026, particularly in AC, although we forecast that they will begin tapering in the second half of the year as global supply chains work toward normalization. At this time, we anticipate that the second half of the year may ultimately resemble the first half, with lower sequential earnings in the third quarter driven by moderation of supply-related opportunities, and fourth quarter earnings that are expected to exceed the first quarter. Given these dynamics, we anticipate adjusted earnings per share in the second half to be approximately $3.00.

With underlying demand across our key end markets remaining weak, our second-half performance will be driven by our ability to capture value through commercial excellence and the differentiation of our global production and supply chain networks, amid real-time supply dynamics.

Our focus remains on delivering controllable improvements across the businesses in support of our three strategic priorities of increasing cash flow to deleverage the balance sheet, intensifying cost improvements, and driving top-line growth. The earnings improvement we currently expect through 2026 would meaningfully accelerate our deleveraging trajectory - our top priority. Based on current expectations, we anticipate ending the year with a net debt to operating EBITDA ratio in the vicinity of 4.8x. Across all market environments, disciplined execution of our action plans remains central to driving improved and more resilient performance. We remain confident that the unique competitive advantages of our two businesses will continue to strengthen Celanese and support long-term, sustainable value creation.

All forward-looking statements are based upon current expectations and beliefs and various assumptions. There can be no assurance that the Company will realize these expectations or that these beliefs will prove correct. There are a number of risks and uncertainties that could cause actual results to differ materially from the results expressed or implied in the forward-looking statements contained in this presentation.

**Exhibit 99.2**

**<u>Non-U.S. GAAP Financial Measures and Supplemental Information</u>**

**May 5, 2026**

*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-U.S. 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-U.S. 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 U.S. 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 U.S. 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 U.S. 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 U.S. 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* 

------

![celogoa.jpg](celogoa.jpg)

*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*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *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 <u>[Table 8](#i0cb2100c0a7047b2a8bbd3d4a5b5756a_43)</u>). 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.*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *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. We do not provide reconciliations for operating EBITDA 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. 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.*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• 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.*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• 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. <u>[Table 3a](#i0cb2100c0a7047b2a8bbd3d4a5b5756a_22)</u> 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.*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• 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.* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• 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.*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• 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:*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• 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.*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Cash dividends received from our equity investments.*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• 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.* 

*Certain prior period amounts have been revised to correct for certain prior period immaterial errors. See Note 1 to our Quarterly Report on Form 10-Q for the quarterly period ending March 31, 2026.*
