The unaudited interim consolidated financial statements for the three and ~~nine~~six months ended ~~September~~June 30, ~~2016~~2017 and ~~2015~~2016 contained in this Quarterly Report were prepared in accordance with accounting principles generally accepted in the United States of America ("US GAAP") for all periods presented and include the accounts of the Company, its majority owned subsidiaries over which the Company exercises control and, when applicable, variable interest entities in which the Company is the primary beneficiary. The unaudited interim consolidated financial statements and other financial information included in this Quarterly Report, unless otherwise specified, have been presented to separately show the effects of discontinued operations.

In the opinion of management, the accompanying unaudited consolidated balance sheets and related unaudited interim consolidated statements of operations, comprehensive income (loss), cash flows and equity include all adjustments, consisting only of normal recurring items necessary for their fair presentation in conformity with US GAAP. Certain information and footnote disclosures normally included in financial statements prepared in accordance with US GAAP may have been condensed or omitted in accordance with rules and regulations of the Securities and Exchange Commission ("SEC"). These unaudited interim consolidated financial statements should be read in conjunction with the Company's consolidated financial statements as of and for the year ended December 31, ~~2015~~2016, filed on February ~~5, 2016~~10, 2017 with the SEC as part of the Company's Annual Report on Form 10-K.

Operating results for the three and ~~nine~~six months ended ~~September~~June 30, ~~2016~~2017 are not necessarily indicative of the results to be expected for the entire year.

In the ordinary course of business, the Company enters into contracts and agreements relative to a number of topics, including acquisitions, dispositions, joint ventures, supply agreements, product sales and other arrangements. The Company endeavors to describe those contracts or agreements that are material to its business, results of operations or financial position. The Company may also describe some arrangements that are not material but in which the Company believes investors may have an interest or which may have been included in a Form 8-K filing. Investors should not assume the Company has described all contracts and agreements relative to the Company's business in this Quarterly Report.

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 noncontrolling interests.

The Company has reclassified certain prior period amounts to conform to the current period's presentation.

Estimates and Assumptions

The preparation of unaudited interim consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the unaudited interim consolidated financial statements and the reported amounts of ~~net~~Net sales, expenses and allocated charges during the reporting period. Significant estimates pertain to impairments of goodwill, intangible assets and other long-lived assets, purchase price allocations, restructuring costs and other (charges) gains, net, income taxes, pension

and other postretirement benefits, asset retirement obligations, environmental liabilities and loss contingencies, among others. Actual results could differ from those estimates.

~~Goodwill and Other Intangible Assets~~

~~The Company assesses the recoverability~~

Table of the carrying amount of its reporting unit goodwill either qualitatively or quantitatively annually during the third quarter of its fiscal year using June 30 balances or whenever events or changes in circumstances indicate that the carrying amount of the asset may not be fully recoverable. In connection with the Company's annual goodwill impairment assessment, the Company did not record an impairment loss to goodwill during the nine months ended September 30, 2016 as the estimated fair value for each of the Company's reporting units exceeded the carrying amount of the underlying assets by a substantial margin.Contents

The Company assesses the recoverability of the carrying amount of its indefinite-lived intangible assets either qualitatively or by utilizing the relief from royalty method under the income approach annually during the third quarter of its fiscal year using June 30 balances or whenever events or changes in circumstances indicate that the carrying amount of the assets may not be fully recoverable. In connection with the Company's annual indefinite-lived intangible assets impairment assessment, the Company did not record an impairment loss to indefinite-lived intangible assets during the nine months ended September 30, 2016 as the estimated fair value of each of the Company's indefinite-lived intangible assets exceeded the carrying value of the underlying assets by a substantial margin.

~~The Company's trademarks and trade names have an indefinite life. For the nine months ended September 30, 2016, the Company did not renew or extend any intangible assets.~~

Change in ~~estimate~~accounting policy regarding ~~pension and other postretirement benefits~~share-based compensation

~~Beginning in 2016,~~Historically, the Company recognized share-based compensation net of estimated forfeitures over the vesting period of the respective grant. Effective January 1, 2017, the Company elected to change ~~the method used~~its accounting policy to ~~estimate the service and interest cost components~~recognize forfeitures as they occur. The new forfeiture policy election was adopted using a modified retrospective approach with a cumulative effect adjustment of ~~net periodic benefit cost~~$1 million to Retained earnings as of January 1, 2017. See Note 2 - Recent Accounting Pronouncements for its significant defined benefit pension plans and other postretirement benefit plans. Previously, the Company estimated the service and interest cost components utilizing a single weighted average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. further information.

2. Recent Accounting Pronouncements

The Company has elected to use a full yield curve approach in the estimation of these components of net periodic benefit cost by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. This change improves the correlation between projected benefit cash flows and the corresponding yield curve spot rates andfollowing table provides a ~~more precise measurement~~brief description of ~~service and interest costs. This change does not affect~~recent Accounting Standard Updates ("ASU") issued by the measurement of the Company's total benefit obligations as the change in service and interest cost will be completely offset in the annual actuarial (gain) loss reported. The Company has accounted for this change as a change in estimate and, accordingly, has accounted for it prospectively beginning in 2016. The Company's adoption of the full yield curve approach will reduce 2016 service and interest cost by approximately $29 million as compared to the previous method.Financial Accounting Standards Board ("FASB"):

The discount rates used to measure service and interest cost during 2016 and the discount rates that would have been used for service and interest cost under the Company's previous estimation methodology are as follows:

On June 18, 2017, Celanese, through various subsidiaries, entered into an agreement with affiliates of The Blackstone Group L.P. (the "Blackstone Entities") to form a joint venture which combines substantially all of the ~~Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-15,~~ ~~Classification~~operations of ~~Certain Cash Receipts~~the Company's cellulose derivatives business and ~~Cash Payments~~ ~~("ASU 2016-15").

The Company's cellulose derivatives operations are included in the ~~statement~~Consumer Specialties segment. The combined business will operate under a common governance structure through two separate joint ventures, each of which will be owned ultimately 70 percent and 30 percent by Celanese and the Blackstone Entities, respectively. One venture will primarily be comprised of the US operations being contributed and the other will be comprised of the remaining international operations being contributed. Closing of the transaction is subject to customary closing conditions, including: (i) waiting periods, clearances and/or approvals of the European Union and other jurisdictions requiring antitrust or similar approvals, and (ii) completion of the internal reorganization of the Company's cellulose derivatives business to facilitate the closing and operation of the joint venture post-closing. The agreement may be terminated by Celanese and/or the Blackstone Entities under certain limited circumstances, including if the closing is not consummated within one year of signing, which date may be extended by an additional 90 days, under certain circumstances. Pursuant to the terms of the agreement, once approved and upon closing, the Company is expected to consolidate the joint venture results, subject to the Blackstone Entities' noncontrolling interest.

In connection with the agreement, the joint venture obtained commitments for credit facilities aggregating $2.4 billion to be entered into by the joint venture entities at the closing consisting of (i) senior secured ($135 million) and senior unsecured ($65 million) revolving credit facilities in an aggregate principal amount of $200 million, (ii) senior secured term loan facilities in an aggregate principal amount of $1.0 billion, (iii) a senior unsecured bridge facility in an aggregate principal amount of $800 million, which bridge facility will backstop the proposed issuance of $800 million senior unsecured notes by a joint venture subsidiary, and (iv) a senior unsecured term loan facility in an aggregate principal amount of $400 million. The credit facilities will be guaranteed by certain of the subsidiaries of the respective borrowers; however, only the $65 million senior unsecured revolving credit facility and the $400 million senior unsecured term loan credit facility will be guaranteed by Celanese. Approximately $2.2 billion of the proceeds of the debt financing are expected to be used, in part, to repay certain of the parties' existing indebtedness and a $1.6 billion dividend to the Company.

Nilit Plastics

~~In November 2015, the FASB issued ASU 2015-17,~~ ~~Balance Sheet Classification of Deferred Taxes~~ ("ASU 2015-17"). ASU 2015-17 requires deferred tax liabilities and assets to be classified as noncurrent in a classified statement of financial position. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early adoption is permitted. The Company elected to early adopt ASU 2015-17 prospectively during the three months ended March 31, 2016 in accordance with the FASB's disclosure simplification initiatives. The adoption of this ASU resulted in a reclassification from current to noncurrent deferred tax assets and deferred tax liabilities as of March 31, 2016 of $68 million and $30 million, respectively. Prior periods were not adjusted.

~~In May 2014, the FASB issued ASU 2014-09,~~ ~~Revenue from Contracts with Customers~~ ~~("ASU 2014-09")~~.

During the six months ended June 30, 2017, transaction related costs of $1 million were expensed as incurred to Selling, general and administrative expenses in the unaudited interim consolidated statements of operations. The amount of pro forma Net earnings (loss) of Nilit included in the Company's unaudited interim consolidated statement of operations was less than 1% (unaudited) of its consolidated Net earnings (loss) had the acquisition occurred as of the beginning of 2017. The amount of Nilit Net earnings (loss) consolidated by the Company since the acquisition date was not material.

SO.F.TER. S.p.A.

In December 2016, the Company acquired 100% of the stock of the Forli, Italy based SO.F.TER. S.p.A. ("SOFTER"), a leading thermoplastic compounder. The acquisition of SOFTER increases the Company's global engineered materials product platforms, extends the operational model, technical and industry solutions capabilities and expands project pipelines. The acquisition was accounted for as a business combination and the acquired operations are included in the Advanced Engineered Materials segment. The Company allocated the purchase price of the acquisition to identifiable assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. The purchase price allocation was based on preliminary information and is subject to change if additional information about the facts and circumstances that existed at the acquisition date becomes available. The final fair value of the net assets acquired may result in adjustments to the assets and liabilities, including goodwill. During the six months ended June 30, 2017, the Company made adjustments to its purchase price allocation which primarily resulted in an increase of $3 million in property, plant and equipment and a reduction to goodwill of the same amount. Any subsequent measurement period adjustments are not expected to have a material impact on the Company's results of operations.

3.4. Ventures and Variable Interest Entities

Consolidated Variable Interest Entities

~~In February 2014, the~~The Company ~~formed~~has a joint venture, Fairway Methanol LLC ("Fairway"), with Mitsui & Co., Ltd., of Tokyo, Japan ("Mitsui"), in which the Company owns 50% of Fairway, for the production of methanol at the Company's integrated chemical plant in Clear Lake, Texas. The methanol unit utilizes natural gas in the US Gulf Coast region as a feedstock and benefits from the existing infrastructure at the Company's Clear Lake facility. Both Mitsui and the Company supply their own natural gas to Fairway in exchange for methanol tolling under a cost-plus off-take arrangement.

The Company determined that Fairway is a variable interest entity ("VIE") in which the Company is the primary beneficiary. Under the terms of the joint venture agreements, the Company provides site services and day-to-day operations for the methanol facility. In addition, the joint venture agreements provide that the Company indemnifies Mitsui for environmental obligations that exceed a specified threshold, as well as an equity option between the partners. Accordingly, the Company consolidates the venture and records a noncontrolling interest for the share of the venture owned by Mitsui. Fairway is included in the Company's Acetyl Intermediates segment.

The carrying amount of the assets and liabilities associated with Fairway included in the unaudited consolidated balance sheets are as follows:

Nonconsolidated Variable Interest Entities

The Company holds variable interests in entities that supply certain raw materials and services to the Company. The variable interests primarily relate to cost-plus contractual arrangements with the suppliers and recovery of capital expenditures for certain plant assets plus a rate of return on such assets. Liabilities for such supplier recoveries of capital expenditures have been recorded as capital lease obligations. The entities are not consolidated because the Company is not the primary beneficiary of the entities as it does not have the power to direct the activities of the entities that most significantly impact the entities' economic performance. The Company's maximum exposure to loss as a result of its involvement with these VIEs as of ~~September~~June 30, ~~2016~~2017 relates primarily to the recovery of capital expenditures for certain property, plant and equipment.

Covenants

The Company's material financing arrangements contain customary covenants, including the maintenance of certain financial ratios, events of default and change of control provisions.

The Company is in compliance with all of the covenants related to its debt agreements as of ~~September~~June 30, ~~2016~~2017.

~~9. Benefit Obligations~~

Beginning in 2016, the Company elected to use a full yield curve approach in the estimation of the service and interest cost components of net periodic benefit cost by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows (~~Note 1). The Company's adoption of the full yield curve approach will reduce 2016 service and interest cost by approximately $29 million as compared to the previous method.~~

Remediation

Due to its industrial history and through retained contractual and legal obligations, the Company has the obligation to remediate specific areas on its own sites as well as on divested, demerger, orphan or US Superfund sites (as defined below). In addition, as part of the demerger agreement between the Company and Hoechst AG ("Hoechst"), a specified portion of the responsibility for environmental liabilities from a number of Hoechst divestitures was transferred to the Company (Note 1618). The Company provides for such obligations when the event of loss is probable and reasonably estimable. The Company believes that environmental remediation costs will not have a material adverse effect on the financial position of the Company, but may have a material adverse effect on the results of operations or cash flows in any given period.

US Superfund Sites

In the US, the Company may be subject to substantial claims brought by US federal or state regulatory agencies or private individuals pursuant to statutory authority or common law. In particular, the Company has a potential liability under the US Federal Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, and related state laws (collectively referred to as "Superfund") for investigation and cleanup costs at certain sites. At most of these sites, numerous companies, including the Company, or one of its predecessor companies, have been notified that the US Environmental Protection Agency ("EPA"), state governing bodies or private individuals consider such companies to be potentially responsible parties ("PRP") under Superfund or related laws. The proceedings relating to these sites are in various stages. The cleanup process has not been completed at most sites, and the status of the insurance coverage for some of these proceedings is uncertain. Consequently, the Company cannot accurately determine its ultimate liability for investigation or cleanup costs at these sites.

As events progress at each site for which it has been named a PRP, the Company accrues, as appropriate, a liability for site cleanup. Such liabilities include all costs that are probable and can be reasonably estimated. In establishing these liabilities, the Company considers the contaminants of concern, the potential impact thereof, the relationship of the contaminants of concern to its current and historic operations, its shipment of waste to a site, its percentage of total waste shipped to the site, the types of wastes involved, the conclusions of any studies, the magnitude of any remedial actions that may be necessary and the number and viability of other PRPs. Often the Company joins with other PRPs to sign joint defense agreements that settle, among PRPs, each party's percentage allocation of costs at the site. Although the ultimate liability may differ from the estimate, the Company routinely reviews the liabilities and revises the estimate, as appropriate, based on the most current information available.

One such site is the Diamond Alkali Superfund Site, which is comprised of a number of sub-sites, including the Lower Passaic River Study Area, which is the lower 17-mile stretch of the Passaic River ("Lower Passaic River Site")., and the Newark Bay Area. The Company and 70 other companies are parties to a May 2007 Administrative Order on Consent with the EPA to perform a Remedial Investigation/Feasibility Study ("RI/FS") at the Lower Passaic River Site in order to identify the levels of contaminants and potential cleanup ~~actions.~~actions, including the potential migration of contaminants between the Lower Passaic River Site and the Newark Bay Area. Work on the RI/FS is ongoing, with a goal to complete it in ~~2017.~~2018.

OnIn March 3, 2016, the EPA issued its final Record of Decision concerning the remediation of the lower 8.3 miles of the Lower Passaic River Site ("Lower 8.3 Miles"). Pursuant to the EPA's Record of Decision, the Lower 8.3 Miles must be dredged bank to bank and an engineered cap must be installed at an EPA estimated cost of approximately $1.4 billion. The Company owned and/or operated facilities in the vicinity of the Lower 8.3 Miles, but has found no evidence that it contributed any of the primary contaminants of concern to the Passaic River. ~~Pursuant to the EPA's Record of Decision, the Lower 8.3 Miles must be dredged bank to bank and an engineered cap must be installed at an estimated cost of approximately $1.4 billion.~~ The Company is vigorously defending this matter and currently believes

that its ultimate allocable share of the cleanup costs with respect to the Lower Passaic River Site, estimated at less than 1%, will not be material.

~~During~~A partner in the Company's InfraServ equity affiliate investments exercised an option right, which is currently being disputed, to purchase additional ownership interests in the InfraServ entities from the Company. The purchase of these interests will reduce the Company's ownership interests in InfraServ GmbH & Co. Gendorf KG and InfraServ GmbH & Co. Knapsack KG from 39 percent and 27 percent, to 30 percent and 22 percent, respectively. Accordingly, during the three months ended ~~September~~June 30, ~~2015,~~2017, the Company reduced the carrying value of these investments by $4 million. In addition, the Company has reserved certain amounts for dividends received from the investments since the exercise notification was received. The Company's InfraServ investments are primarily owned by entities included in the Other Activities segment.

During the six months ended June 30, 2017, the Company provided notice of termination of a contract with a key raw materials supplier at its ethanol production unit in Nanjing, China. As a result, the Company recorded $6an estimated $50 million of plant/office closure costs primarily consisting of a $24 million contract termination charge and $4an $18 million ~~respectively, in accelerated depreciation related~~reduction to ~~the Company's vinyl acetate ethylene ("VAE") emulsions~~its non-income tax receivable. The Nanjing, China ethanol production unit in Meredosia, Illinois and its VAE and conventional emulsions units in Tarragona, Spain. The accelerated depreciation is included in Cost of sales in the unaudited interim consolidated statements of operations and is included in the Company's Industrial Specialties segment.

During the nine months ended September 30, 2015, the Company also recorded $39 million in accelerated depreciation expense related to property, plant and equipment no longer in use at the Company's ethanol technology development unit in Clear Lake, Texas. The Company believes that further development of its ethanol technology can be achieved through the utilization of other existing assets. The accelerated depreciation is included in Research and development expenses in the unaudited interim consolidated statements of operations and is included in the Company's Acetyl Intermediates segment.

The changes in the restructuring reserves by business segment are as follows:

The lower effective income tax rate for the three ~~and nine~~ months ended ~~September~~June 30, ~~2016~~2017 compared to the same period in ~~2015~~2016 is primarily due to ~~remeasurement of prior year tax positions due to audit closures and technical clarifications~~foreign exchange losses in certain jurisdictions where the functional currency differs from the local currency and a release of ~~$52 million.~~a tax position due to an audit settlement in Germany.

For the ~~nine~~six months ended ~~September~~June 30, ~~2016,~~2017, the Company's uncertain tax positions ~~decreased $61~~increased $21 million, primarily due to ~~audit closures in~~ the USNilit acquisition (Note 3) and ~~in certain~~ foreign ~~jurisdictions.~~exchange fluctuations.

The Company's US tax returns for the years 2009 through 2012 are currently under audit by the US Internal Revenue Service and certain of the Company's subsidiaries are under audit in jurisdictions outside of the US. In connection with the Company's US federal income tax audit for 2009 and 2010, the Company has received $192 million of proposed pre-tax adjustments related to various intercompany charges. In the event the Company is wholly unsuccessful in its defense, an actual tax assessment would result in the consumption of up to $67 million of prior foreign tax credit carryforwards. The Company believes these proposed adjustments to be without merit and is vigorously defending its position.

~~14.~~16. Derivative Financial Instruments

~~Cash Flow Hedges~~

~~Cross-currency Swaps~~

In March 2015, the Company settled its cross-currency swap agreements with notional values of $250 million/€193 million, expiring September 11, 2020, and $225 million/€162 million, expiring April 17, 2019, in exchange for cash of $88 million. The Company recorded a net loss of $1 million, which is included in Other income (expense), net in the unaudited interim consolidated statement of operations. The Company classifies cash flows from derivative instruments designated as cash flow hedges in the same category of the consolidated statement of cash flows as the cash flows from the items being hedged. Accordingly, the settlement of the cross-currency swap agreements is included in Net cash provided by (used in) operating activities in the unaudited interim consolidated statement of cash flows for the nine months ended September 30, 2015.

Net Investment Hedges

The Company uses derivative instruments, such as foreign currency forwards, and non-derivative financial instruments, such as foreign currency denominated debt, that may give rise to foreign currency transaction gains or losses to hedge the foreign currency exposure of net investments in foreign operations. Accordingly, the effective portion of gains and losses from remeasurement of derivative and non-derivative financial instruments is included in foreign currency translation within

17. Fair Value Measurements

The Company's financial assets and liabilities are measured at fair value on a recurring basis as follows:

Derivatives. Derivative financial instruments, including commodity swaps and foreign currency forwards and swaps, are valued in the market using discounted cash flow techniques. These techniques incorporate Level 1 and Level 2 fair value measurement inputs such as spot rates and foreign currency exchange rates. These market inputs are utilized in the discounted cash flow calculation considering the instrument's term, notional amount, discount rate and credit risk. Significant inputs to the derivative valuation for commodity swaps and foreign currency forwards and swaps are observable in the active markets and are classified as Level 2 in the fair value measurement hierarchy.

In general, the cost investments included in the table above are not publicly traded and their fair values are not readily determinable; however, the Company believes the carrying values approximate or are less than the fair values. Insurance contracts in nonqualified trusts consist of long-term fixed income securities, which are valued using independent vendor pricing models with observable inputs in the active market and therefore represent a Level 2 fair value measurement. The fair value of

~~Table of Contents~~

long-term debt is based on valuations from third-party banks and market quotations and is classified as Level 2 in the fair value measurement hierarchy. The fair value of obligations under capital leases, which are included in long-term debt, is based on lease payments and discount rates, which are not observable in the market and therefore represents a Level 3 fair value measurement.

As of ~~September~~June 30, ~~2016~~2017 and December 31, ~~2015~~2016, the fair values of cash and cash equivalents, receivables, trade payables, short-term borrowings and the current installments of long-term debt approximate carrying values due to the short-term nature of these instruments. These items have been excluded from the table with the exception of the current installments of long-term debt.

~~16.~~18. Commitments and Contingencies

Commitments

Guarantees

The Company has agreed to guarantee or indemnify third parties for environmental and other liabilities pursuant to a variety of agreements, including asset and business divestiture agreements, leases, settlement agreements and various agreements with affiliated companies. Although many of these obligations contain monetary and/or time limitations, others do not provide such limitations. The Company has accrued for all probable and reasonably estimable losses associated with all known matters or claims. These known obligations include the following:

Demerger Obligations

In connection with the Hoechst demerger, the Company agreed to indemnify Hoechst, and its legal successors, for various liabilities under the demerger agreement, including for environmental liabilities associated with contamination arising either from environmental damage in general ("Category A") or under 19 divestiture agreements entered into by Hoechst prior to the demerger ("Category B") (Note 1012).

The Company's obligation to indemnify Hoechst, and its legal successors, is capped under Category B at €250 million. If and to the extent the environmental damage should exceed €750 million in aggregate, the Company's obligation to indemnify Hoechst and its legal successors applies, but is then limited to 33.33% of the remediation cost without further limitations. Cumulative payments under the divestiture agreements as of ~~September~~June 30, ~~2016~~2017 are ~~$74~~$77 million. Most of the divestiture agreements have become time barred and/or any notified environmental damage claims have been partially settled.

Table of Contents

The Company has also undertaken in the demerger agreement to indemnify Hoechst and its legal successors for (i) 33.33% of any and all Category A liabilities that result from Hoechst being held as the responsible party pursuant to public law or current or future environmental law or by third parties pursuant to private or public law related to contamination and (ii) liabilities that Hoechst is required to discharge, including tax liabilities, which are associated with businesses that were included in the demerger but were not demerged due to legal restrictions on the transfers of such items. These indemnities do not provide for any monetary or time limitations. The Company has not been requested by Hoechst to make any payments in connection with this indemnification. Accordingly, the Company has not made any payments to Hoechst and its legal successors.

Based on the Company's evaluation of currently available information, including the lack of requests for indemnification, the Company cannot estimate the Possible Loss for the remaining demerger obligations, if any, in excess of amounts accrued.

Divestiture Obligations

The Company and its predecessor companies agreed to indemnify third-party purchasers of former businesses and assets for various pre-closing conditions, as well as for breaches of representations, warranties and covenants. Such liabilities also include environmental liability, product liability, antitrust and other liabilities. These indemnifications and guarantees represent standard contractual terms associated with typical divestiture agreements and, other than environmental liabilities, the Company does not believe that they expose the Company to any significant risk (Note 1012).

The Company has divested numerous businesses, investments and facilities through agreements containing indemnifications or guarantees to the purchasers. Many of the obligations contain monetary and/or time limitations, which extend through 2037. The aggregate amount of outstanding indemnifications and guarantees provided for under these agreements is ~~$202~~$124 million as of ~~September~~June 30, ~~2016.~~2017. Other agreements do not provide for any monetary or time limitations.

~~Table of Contents~~

Based on the Company's evaluation of currently available information, including the number of requests for indemnification or other payment received by the Company, the Company cannot estimate the Possible Loss for the remaining divestiture obligations, if any, in excess of amounts accrued.

Purchase Obligations

In the normal course of business, the Company enters into various purchase commitments for goods and services. The Company maintains a number of "take-or-pay" contracts for purchases of raw materials, utilities and other services. Certain of the contracts contain a contract termination buy-out provision that allows for the Company to exit the contracts for amounts less than the remaining take-or-pay obligations. ~~The Company does not expect to incur any material losses under take-or-pay contractual arrangements.~~ Additionally, the Company has other outstanding commitments representing maintenance and service agreements, energy and utility agreements, consulting contracts and software agreements. As of ~~September~~June 30, ~~2016,~~2017, the Company had unconditional purchase obligations of ~~$2.6~~$1.9 billion, which extend through 2036.

Contingencies

The Company is involved in legal and regulatory proceedings, lawsuits, claims and investigations incidental to the normal conduct of business, relating to such matters as product liability, land disputes, commercial contracts, employment, antitrust or competition compliance, intellectual property, workers' compensation, chemical exposure, asbestos exposure, taxes, trade compliance, prior acquisitions and divestitures, claims of legacy stockholders, past waste disposal practices and release of chemicals into the environment. The Company is actively defending those matters where the Company is named as a defendant and, based on the current facts, does not believe the outcomes from these matters would be material to ~~our~~the Company's results of operations, cash flows or financial position.

European Commission

In May 2017, the Company learned that the European Commission has opened a competition law investigation involving certain subsidiaries of the Company with respect to certain raw material purchases. The Company is cooperating with the European Commission. Because of the early stage of the investigation and the many uncertainties and variables involved, the Company is unable at this time to determine the outcome of this investigation and whether, and in what amount, any potential fines would be assessed.

~~19.~~21. Consolidating Guarantor Financial Information

The Senior Notes were issued by Celanese US ("Issuer") and are guaranteed by Celanese Corporation ("Parent Guarantor") and the Subsidiary Guarantors (Note 810). The Issuer and Subsidiary Guarantors are 100% owned subsidiaries of the Parent Guarantor. The Parent Guarantor and Subsidiary Guarantors have guaranteed the Notes fully and unconditionally and jointly and severally.

For cash management purposes, the Company transfers cash between the Parent Guarantor, Issuer, Subsidiary Guarantors and non-guarantors through intercompany financing arrangements, contributions or declaration of dividends between the respective parent and its subsidiaries. The transfer of cash under these activities facilitates the ability of the recipient to make specified third-party payments for principal and interest on the Company's outstanding debt, Common Stock dividends and Common Stock repurchases. The unaudited interim consolidating statements of cash flows for the ~~nine~~six months ended ~~September~~June 30, ~~2016~~2017 and ~~2015~~2016 present such intercompany financing activities, contributions and dividends consistent with how such activity would be presented in a stand-alone statement of cash flows.

The Company has not presented separate financial information and other disclosures for each of its Subsidiary Guarantors because it believes such financial information and other disclosures would not provide investors with any additional information that would be material in evaluating the sufficiency of the guarantees.

The unaudited interim consolidating financial statements for the Parent Guarantor, the Issuer, the Subsidiary Guarantors and the non-guarantors are as follows:

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

In this Quarterly Report on Form 10-Q ("Quarterly Report"), the term "Celanese" refers to Celanese Corporation, a Delaware corporation, and not its subsidiaries. The terms the "Company," "we," "our" and "us," refer to Celanese and its subsidiaries on a consolidated basis. The term "Celanese US" refers to the Company's subsidiary, Celanese US Holdings LLC, a Delaware limited liability company, and not its subsidiaries.

The following discussion should be read in conjunction with the Celanese Corporation and Subsidiaries consolidated financial statements as of and for the year ended December 31, ~~2015~~2016 filed on February ~~5, 2016~~10, 2017 with the Securities and Exchange Commission ("SEC") as part of the Company's Annual Reporting on Form 10-K ("~~2015~~2016 Form 10-K") and the unaudited interim consolidated financial statements and notes to the unaudited interim consolidated financial statements, which are prepared in accordance with accounting principles generally accepted in the United States of America ("US GAAP").

Investors are cautioned that the forward-looking statements contained in this section and other parts of this Quarterly Report involve both risk and uncertainty. Several important factors could cause actual results to differ materially from those anticipated by these statements. Many of these statements are macroeconomic in nature and are, therefore, beyond the control of management. See "Forward-Looking Statements" below and at the beginning of our ~~2015~~2016 Form 10-K.

Forward-Looking Statements

Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") and other parts of this Quarterly Report contain certain forward-looking statements and information relating to us that are based on the beliefs of our management as well as assumptions made by, and information currently available to, us. Generally, words such as "believe," "expect," "intend," "estimate," "anticipate," "project," "plan," "may," "can," "could," "might," and "will," and similar expressions, as they relate to us are intended to identify forward-looking statements. These statements reflect our current views and beliefs with respect to future events at the time that the statements are made, are not historical facts or guarantees of future performance and involve risks and uncertainties that are difficult to predict and many of which are outside of our control. Further, certain forward-looking statements are based upon assumptions as to future events that may not prove to be accurate. All forward-looking statements made in this Quarterly Report are made as of the date hereof, and the risk that actual results will differ materially from expectations expressed in this Quarterly Report will increase with the passage of time. We undertake no obligation, and disclaim any duty, to publicly update or revise any forward-looking statements, whether as a result of new information, future events, changes in our expectations or otherwise.

Risk Factors

See Part I - Item 1A. Risk Factors of our ~~2015~~2016 Form 10-K and subsequent periodic filings we make with the SEC for a description of certain risk factors that you should consider which could significantly affect our financial results. In addition, the following factors could cause our actual results to differ materially from those results, performance or achievements that may be expressed or implied by such forward-looking statements. These factors include, among other things:

changes in general economic, business, political and regulatory conditions in the countries or regions in which we operate;

the length and depth of product and industry business cycles particularly in the automotive, electrical, textiles, electronics and construction industries;

changes in the price and availability of raw materials, particularly changes in the demand for, supply of, and market prices of ethylene, methanol, natural gas, wood pulp and fuel oil and the prices for electricity and other energy sources;

the ability to pass increases in raw material prices on to customers or otherwise improve margins through price increases;

the ability to maintain plant utilization rates and to implement planned capacity additions, expansions and ~~expansions;~~maintenance;

the ability to reduce or maintain current levels of production costs and to improve productivity by implementing technological improvements to existing plants;

increased price competition and the introduction of competing products by other companies;

the ability to identify desirable potential acquisition targets and to consummate acquisition or investment transactions, including obtaining regulatory approvals, consistent with our strategy;

Table of Contents

market acceptance of our technology;

the ability to obtain governmental approvals and to construct facilities on terms and schedules acceptable to us;

~~Table of Contents~~

changes in the degree of intellectual property and other legal protection afforded to our products or technologies, or the theft of such intellectual property;

compliance and other costs and potential disruption or interruption of production or operations due to accidents, interruptions in sources of raw materials, cyber security incidents, terrorism or political unrest, or other unforeseen events or delays in construction or operation of facilities, including as a result of geopolitical conditions, the occurrence of acts of war or terrorist incidents or as a result of weather or natural disasters;

potential liability for remedial actions and increased costs under existing or future environmental regulations, including those relating to climate change;

potential liability resulting from pending or future claims or litigation, including investigations or enforcement actions, or from changes in the laws, regulations or policies of governments or other governmental activities, in the countries in which we operate;

changes in currency exchange rates and interest rates;

our level of indebtedness, which could diminish our ability to raise additional capital to fund operations or limit our ability to react to changes in the economy or the chemicals industry; and

various other factors, both referenced and not referenced in this Quarterly Report.

Many of these factors are macroeconomic in nature and are, therefore, beyond our control. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, our actual results, performance or achievements may vary materially from those described in this Quarterly Report as anticipated, believed, estimated, expected, intended, planned or projected. We neither intend nor assume any obligation to update these forward-looking statements, which speak only as of their dates.

Table of the Treasury announced the issuance of proposed regulations regarding corporate tax inversions and related earnings stripping. These proposed regulations, which were to be effective 90 days after finalization, included provisions that may be interpreted to impact other common tax structures including intercompany financing and obligations. Subsequent to the balance sheet date of September 30, 2016, on October 13, 2016, the US Department of Treasury issued the final regulations.

Depreciation and amortization expense, which is included within Operating profit (loss), decreased during the nine months ended September 30, 2016 compared to the same period in 2015 as a result of $39 million in accelerated depreciation expense in the prior year related to property, plant and equipment no longer in use at our ethanol technology unit in Clear Lake, Texas, which did not recur in the current year, partially offset by the impact from the startup of production at the Fairway facility in October 2015.

Operating loss ~~decreased~~increased for the ~~nine~~three months ended ~~September~~June 30, ~~2016~~2017 compared to the same period in ~~2015~~2016 primarily due to:

~~lower~~higher functional spending and incentive compensation ~~costs~~costs; and

•

an unfavorable impact to Other (charges) gains, net of $3 million. A partner in our InfraServ equity affiliate investments exercised an option right, which is currently being disputed, to purchase additional ownership interests in the InfraServ entities from us. The purchase of these interests will reduce our ownership interests in InfraServ GmbH & Co. Gendorf KG and InfraServ GmbH & Co. Knapsack KG. Accordingly, during the three months ended June 30, 2017, we reduced the carrying value of these investments by $4 million. See Note 14 - Other (Charges) Gains, Net in the accompanying unaudited interim consolidated financial statements for further information.

Equity in net earnings (loss) of ~~$12 million.~~affiliates decreased for the three months ended June 30, 2017 compared to the same period in 2016 primarily due to:

a decrease in equity investment in earnings of $4 million for InfraServ GmbH & Co. Gendorf KG and InfraServ GmbH & Co. Knapsack KG associated with a reserve for dividends received from these investments since the exercise notification was received.

Six Months Ended June 30, 2017 Compared to Six Months Ended June 30, 2016

Operating loss increased for the six months ended June 30, 2017 compared to the same period in 2016 primarily due to:

higher functional and project spending; and

an unfavorable currency impact resulting from a strong US dollar relative to the Euro and Chinese Yuan.

Equity in net earnings (loss) of affiliates decreased for the six months ended June 30, 2017 compared to the same period in 2016 primarily due to:

Liquidity and Capital Resources

Our primary source of liquidity is cash generated from operations, available cash and cash equivalents and dividends from our portfolio of strategic investments. In addition, as of ~~September~~June 30, ~~2016,~~2017, we have ~~$1.0 billion~~$800 million available for borrowing under our senior unsecured revolving credit facility and ~~$53~~$10 million available under our accounts receivable securitization facility to assist, if required, in meeting our working capital needs and other contractual obligations.

While our contractual obligations, commitments and debt service requirements over the next several years are significant, we continue to believe we will have available resources to meet our liquidity requirements, including debt service, for the next twelve months. If our cash flow from operations is insufficient to fund our debt service and other obligations, we may be required to use other means available to us such as increasing our borrowings, reducing or delaying capital expenditures, seeking additional capital or seeking to restructure or refinance our indebtedness. There can be no assurance, however, that we will continue to generate cash flows at or above current levels.

Total cash outflows for capital expenditures are expected to be in the range of $250 million to $300 million in ~~2016~~2017 primarily due to additional investments in growth opportunities in our Advanced Engineered Materials and Acetyl Intermediates segments.

On a stand-alone basis, Celanese and its immediate 100% owned subsidiary, Celanese US, have no material assets other than the stock of their subsidiaries and no independent external operations of their own. Accordingly, they generally depend on the cash flow of their subsidiaries and their ability to pay dividends and make other distributions to Celanese and Celanese US in order to meet their obligations, including their obligations under senior credit facilities and senior notes and to pay dividends on our Series A common stock, par value $0.0001 per share ("Common Stock").

Cash Flows

Cash and cash equivalents ~~increased $285~~decreased $127 million to ~~$1.3 billion~~$511 million as of ~~September~~June 30, ~~2016~~2017 compared to December 31, ~~2015.~~2016. As of ~~September~~June 30, ~~2016, $561~~2017, $410 million of the ~~$1.3 billion~~$511 million of cash and cash equivalents was held by our foreign subsidiaries. If these funds are needed for our operations in the US, we will access such funds in a tax efficient manner to satisfy cash flow needs. Currently, there are no planned cash distributions that would result in incremental US taxes payable in excess of applicable foreign tax credits related to such undistributed earnings. As a result, we have not recorded any deferred income taxes on the portion of undistributed foreign earnings determined not to be permanently reinvested in foreign operations.

~~a decrease of $120~~$100 million in share repurchases of our Common ~~Stock.~~Stock; and

an increase in net repayments on long-term debt of $45 million, primarily related to SOFTER bank loans repaid in January 2017.

Debt and Other Obligations

On ~~March 3, 2016, the State of Wisconsin Public Finance Authority completed a $170 million offering of pollution control and industrial revenue bonds, the proceeds of which were loaned to~~June 18, 2017, Celanese, ~~US and used to repay the pollution control and industrial revenue bonds previously issued for our benefit.~~

~~On July 8, 2016, certain of our~~through various subsidiaries, entered into an ~~amendment~~agreement with affiliates of the Blackstone Entities to form a joint venture which combines substantially all of the operations of our ~~accounts receivable securitization facility, extending its maturity~~cellulose derivatives business and the operations of the Rhodia Acetow cellulose acetate business owned by the Blackstone Entities. Closing of the transaction is subject to ~~July 2019 and decreasing~~customary closing conditions.

In connection with the ~~available amount~~agreement, the joint venture with the Blackstone Entities obtained commitments for credit facilities aggregating $2.4 billion to ~~$120 million.~~

~~On July 15, 2016, Celanese, Celanese US and certain subsidiaries~~be entered into ~~a new senior credit agreement~~by the joint venture entities at the closing consisting of (i) senior secured ($135 million) and senior unsecured ($65 million) revolving credit facilities in an aggregate principal amount of $200 million, (ii) senior secured term loan facilities in an aggregate principal amount of $1.0 billion, (iii) a ~~$500~~senior unsecured bridge facility in an aggregate principal amount of $800 million, which bridge facility will backstop the proposed issuance of $800 million senior unsecured notes by a joint venture subsidiary, and (iv) a senior unsecured term loan ~~and a $1.0 billion senior unsecured revolving credit~~ facility ~~(with a letter of credit sublimit) each maturing~~ in 2021. The proceeds from the new senior unsecured term loan and $409 million of borrowings under the new senior unsecured revolving credit facility were used to repay our Term C-2 and C-3 senior secured credit facilities.

~~On September 26, 2016, Celanese US completed~~ an ~~offering of €750 million in~~aggregate principal amount of ~~the 1.125% Notes in a public offering registered under the Securities Act. Net proceeds from the issuance~~$400 million. The credit facilities will be guaranteed by certain of the ~~1.125% Notes were used to repay $411~~subsidiaries of the respective borrowers; however, only the $65 million ~~of outstanding borrowings under our new~~ senior unsecured revolving credit facility and the $400 million senior unsecured term loan credit facility will be guaranteed by Celanese. Approximately $2.2 billion of the proceeds of the debt financing are expected to be used, in part, to repay certain of the parties' existing indebtedness and a $1.6 billion dividend to Celanese. We plan to use the proceeds of the dividend for general corporate purposes. Additionally, we anticipate that we will incur costs of approximately $40 million prior to the closing to carve out assets and entities in anticipation of contributing these to the joint venture. See Note 3 - Acquisitions, Dispositions and Plant Closures in the accompanying unaudited interim consolidated financial statements for further information.

There have been no material changes to our debt or other obligations described in our ~~2015~~2016 Form 10-K other than those disclosed above and in Note 810 - Debt in the accompanying unaudited interim consolidated financial statements.

On July 17, 2017, our Board of Directors approved a $1.5 billion increase in our Common Stock repurchase authorization.

We also declared a quarterly cash dividend of $0.46 per share on our Common Stock on July 17, 2017, amounting to $63 million. The cash dividend will be paid on August 7, 2017 to holders of record as of July 28, 2017.

Critical Accounting Policies and Estimates

Our unaudited interim consolidated financial statements are based on the selection and application of significant accounting policies. The preparation of unaudited interim consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the unaudited interim consolidated financial statements and the reported amounts of ~~net~~Net sales, expenses and allocated charges during the reporting period. Actual results could differ from those estimates. However, we are not currently aware of any reasonably likely events or circumstances that would result in materially different results.

We describe our significant accounting policies in Note 2 - Summary of Accounting Policies, of the Notes to the Consolidated Financial Statements included in our ~~2015~~2016 Form 10-K. We discuss our critical accounting policies and estimates in MD&A in our ~~2015~~2016 Form 10-K.

~~Table of Contents~~

~~Pension and Other Postretirement Obligations~~

Beginning in 2016, we elected to change the method used to estimate the service and interest cost components of net periodic benefit cost for our significant defined benefit pension plans and other postretirement benefit plans. Previously, we estimated the service and interest cost components utilizing a single weighted average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. We have elected to use a full yield curve approach in the estimation of these components of net periodic benefit cost by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. This change improves the correlation between projected benefit cash flows and the corresponding yield curve spot rates and provides a more precise measurement of service and interest costs. This change does not affect the measurement of our total benefit obligations as the change in service and interest cost will be completely offset in the annual actuarial (gain) loss reported. We have accounted for this change as a change in estimate and, accordingly, have accounted for it prospectively beginning in 2016. The adoption of the full yield curve approach will reduce 2016 service and interest cost by approximately $29 million as compared to the previous method. See ~~Note 1 - Description of the Company and Basis of Presentation~~ ~~in the accompanying unaudited interim consolidated financial statements for further information.~~

Item 4. Controls and Procedures

Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, we have evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15(b) under the Securities Exchange Act of 1934, as amended, as of the end of the period covered by this report. Based on that evaluation, as of ~~September~~June 30, ~~2016,~~2017, the Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures are effective.

Changes in Internal Control Over Financial Reporting

On May 3, 2017, we acquired the nylon compounding division of Nilit Group ("Nilit"). See Note 3 - Acquisitions, Dispositions and Plant Closures in the accompanying unaudited interim consolidated financial statements for further information.

During the period covered by this report, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

The Company is involved in a number of legal and regulatory proceedings, lawsuits and claims incidental to the normal conduct of its business, relating to such matters as product liability, land disputes, contracts, antitrust, intellectual property, workers' compensation, chemical exposure, asbestos exposure, trade compliance, prior acquisitions and divestitures, claims of legacy stockholders, past waste disposal practices and release of chemicals into the environment. The Company is actively defending those matters where it is named as a defendant. Due to the inherent subjectivity of assessments and unpredictability of outcomes of legal proceedings, the Company's litigation accruals and estimates of possible loss or range of possible loss may not represent the ultimate loss to the Company from legal proceedings. See Note 1012 - Environmental and Note 1618 - Commitments and Contingencies in the accompanying unaudited interim consolidated financial statements for a discussion of material environmental matters and material commitments and contingencies related to legal and regulatory proceedings. There have been no significant developments in the "Legal Proceedings" described in our ~~2015~~2016 Form 10-K other than those disclosed in Note 1012 - Environmental and Note 1618 - Commitments and Contingencies in the accompanying unaudited interim consolidated financial statements.
