Exhibit 99.2

Non-US GAAP Financial Measures and Supplemental Information

October 19, 2015

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 business segments in two subtotals, reflecting our two cores, the Acetyl Chain and Materials Solutions, based on similarities among customers, business models and technical processes. The Acetyl Chain includes the Company's Acetyl Intermediates segment and the Industrial Specialties segment. Materials Solutions includes the Company's Advanced Engineered Materials segment and the Consumer Specialties segment. For comparative purposes, the historical financial information included herein has been presented to reflect the Acetyl Chain and Materials Solutions subtotals. There has been no change to the composition of the Company's business segments.

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 as the Company believes them to be important supplemental measures for assessing our financial and operating results and as a means to evaluate 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), cash flow from operating activities, earnings per share or any other US GAAP financial measure. The 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 on the Investor Relations/Financial Information/Non-GAAP Financial Measures page of our website, www.celanese.com, in this document, in the presentation itself or on a Form 8-K in connection with the presentation, 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 supplemental financial disclosure should be considered within the context of our complete audited and unaudited financial results for the given period, which are available on the Investor Relations/Financial Information/SEC Filings page of our website, www.celanese.com.

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, operating EBITDA, operating profit (loss) attributable to Celanese Corporation, adjusted earnings per share, net debt, free cash flow and return on invested capital. 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

1

(loss) attributable to Celanese Corporation; 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; and for free cash flow is cash flow from operations. We do not believe that there is a directly comparable financial measure calculated and presented in accordance with GAAP for return on invested capital.

Definitions

• Adjusted EBIT 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, refinancing expense and taxes, and further adjusted for certain items attributable to Celanese Corporation. 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 may provide guidance on adjusted EBIT but are unable to reconcile forecasted adjusted EBIT to a US GAAP financial measure without unreasonable effort because a forecast of certain items is not practical. Adjusted EBIT by business segment may also be referred to by management as segment income. Adjusted EBIT by core may also be referred to by management as core income.

• Operating EBITDA 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, refinancing expense, taxes and depreciation and amortization, and further adjusted for certain items attributable to Celanese Corporation. Operating EBITDA is equal to adjusted EBIT plus depreciation and amortization, and has the same uses and limitations as adjusted EBIT described above.

• Operating profit (loss) attributable to Celanese Corporation is defined by the Company as operating profit (loss), less earnings (loss) attributable to noncontrolling interests ("NCI").

• Adjusted earnings per share is defined by the Company as earnings (loss) from continuing operations attributable to Celanese Corporation, adjusted for income tax (provision) benefit, certain items, 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 unusual, non-operational or restructuring-related activities that affect comparability. We may provide guidance on adjusted earnings per share but are unable to reconcile forecasted adjusted earnings per share to a GAAP financial measure without unreasonable effort because a forecast of certain items is not practical.

Note: 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, where applicable, and specifically excludes changes in uncertain tax positions, discrete items and other material 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. We also reflect the impact of foreign tax credits when utilized for the adjusted earnings per share tax rate. We analyze this rate quarterly and adjust 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. It is not practical to reconcile our prospective adjusted tax rate to the actual GAAP tax rate in any given future period.

• Free cash flow is defined by the Company as cash flow from operations, less capital expenditures on property, plant and equipment, and adjusted for capital contributions from Mitsui & Co., Ltd. to Fairway Methanol LLC. 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. Although we use free cash flow as a financial measure to assess the performance of 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.

• 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 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.

Supplemental Information

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

• Operating margin, adjusted EBIT margin and operating EBITDA margin for Materials Solutions, the Acetyl Chain and each of our business segments.

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

• Cash dividends received from our equity and cost 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 Methanol LLC for which the Company's ownership percentage is 50%. Amounts referred to as "attributable to Celanese Corporation" are net of any applicable NCI.

Recent Developments

• During the third quarter of 2015, we revised our non-GAAP financial information to simplify its presentation by reducing certain immaterial items that had previously been excluded from the calculation of adjusted EBIT, free cash flow and net debt, as well as revising the calculation of return on invested capital. We believe the changes in methodology of our non-GAAP financial information will provide more meaningful insight into the performance of the Company's primary operations and enhance investors' ability to compare the Company's performance to its peers. The adoption of the changes in methodology has been applied retrospectively to prior periods to facilitate comparability across periods.
