INTERIM FINANCIAL STATEMENTS

Our interim condensed consolidated financial statements (unaudited) and Huntsman International's interim condensed consolidated financial statements (unaudited) were prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP" or "U.S. GAAP") and in management's opinion reflect all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of results of operations, comprehensive income, financial position and cash flows for the periods presented. Results for interim periods are not necessarily indicative of those to be expected for the full year. These condensed consolidated financial statements (unaudited) should be read in conjunction with the audited consolidated financial statements and notes to consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2011 for our Company and Huntsman International.

DESCRIPTION OF BUSINESS

We are a global manufacturer of differentiated organic chemical products and of inorganic chemical products. Our products comprise a broad range of chemicals and formulations, which we market globally to a diversified group of consumer and industrial customers. Our products are used in a wide range of applications, including those in the adhesives, aerospace, automotive, construction products, personal care and hygiene, durable and non-durable consumer products, electronics, medical, packaging, paints and coatings, power generation, refining, synthetic fiber, textile chemicals and dye industries.

HUNTSMAN CORPORATION AND SUBSIDIARIES

HUNTSMAN INTERNATIONAL LLC AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (Continued)

1. GENERAL (Continued)

Since then, we have grown through a series of acquisitions and now own a global portfolio of businesses.

We operate all of our businesses through Huntsman International, our 100% owned subsidiary. Huntsman International is a Delaware limited liability company.

HUNTSMAN CORPORATION AND HUNTSMAN INTERNATIONAL FINANCIAL STATEMENTS

Except where otherwise indicated, these notes relate to the condensed consolidated financial statements (unaudited) for both our Company and Huntsman International. The differences between our financial statements and Huntsman International's financial statements relate primarily to the following:

PRINCIPLES OF CONSOLIDATION

Our condensed consolidated financial statements (unaudited) include the accounts of our wholly-owned and majority-owned subsidiaries and any variable interest entities for which we are the primary beneficiary. All intercompany accounts and transactions have been eliminated, except for intercompany sales between continuing and discontinued operations.

USE OF ESTIMATES

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

RECENT DEVELOPMENTS

Amendment to Credit Agreement

On March 6, 2012, Huntsman International entered into a seventh amendment to its senior secured credit facilities (the "Senior Credit Facilities"). The amendment among other things extended the maturity of our revolving credit facility ("Revolving Facility") from March 2014 to March 2017, increased capacity for revolving commitments to $400 million and extended $346 million of our term loan B facility ("Term Loan B"), which prior to this amendment had a maturity of April 2014, to a new stated maturity of April 2017 ("Extended Term Loan B—Series 2"). The amendment also increased the interest rate margin with respect to Extended Term Loan B—Series 2 to LIBOR plus 3.00%. For more information, see "Note 7. Debt—Direct and Subsidiary Debt—Amendment to Credit Agreement."

2. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

ACCOUNTING PRONOUNCEMENTS ADOPTED DURING 2012

In May 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs , providing a consistent definition of fair value between U.S. GAAP and International Financial Reporting Standards ("IFRSs") as well as developing common requirements for measuring fair value and for disclosing information about fair value measurements in accordance with U.S. GAAP and IFRSs. The amendments in this ASU were effective prospectively for interim and annual periods beginning after December 15, 2011. We adopted the amendments of this ASU effective January 1, 2012, and the initial adoption of the amendments in this ASU did not have a significant impact on our condensed consolidated financial statements (unaudited).

In June 2011, the FASB issued ASU No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income , requiring entities to present net income and other comprehensive income in either a single continuous statement of comprehensive income or in two separate, but consecutive, statements of net income and other comprehensive income. The option to present components of other comprehensive income as part of the statement of equity is eliminated. The amendments do not change the option to present components of other comprehensive income either net of related tax effects or before related tax effects, with one amount shown for the aggregate income tax expense or benefit related to the total of other comprehensive income components. The amendments in this ASU were effective retrospectively for fiscal years, and interim periods within those years, beginning after December 15, 2011. We adopted this ASU effective January 1, 2012 and have presented our consolidated net income and consolidated comprehensive income in two separate, but consecutive, statements.

ACCOUNTING PRONOUNCEMENTS PENDING ADOPTION IN FUTURE PERIODS

In September 2011, the FASB issued ASU No. 2011-08, Intangibles—Goodwill and Other (Topic 350): Testing Goodwill for Impairment . The guidance in this ASU is intended to reduce complexity and costs of the annual goodwill impairment test by providing entities with the option of performing a qualitative assessment to determine whether further impairment testing is necessary. The amendments in this ASU include examples of events and circumstances that might indicate that a reporting unit's fair value is less than its carrying value. The amendments in this ASU are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011 with early adoption permitted. We did not early adopt the provisions of this ASU for our annual impairment test on July 1, 2011 and do not expect the adoption of the amendments in this ASU to have a significant impact on our condensed consolidated financial statements (unaudited).

3. BUSINESS COMBINATIONS

EMA ACQUISITION

On December 30, 2011, we completed the acquisition of EMA Kimya Sistemleri Sanayi ve Ticaret A.S. (the "EMA Acquisition"), an MDI-based polyurethanes systems house in Istanbul, Turkey for

approximately $11 million, net of cash acquired and including the repayment of assumed debt. We have accounted for the EMA Acquisition using the acquisition method and transaction costs charged to expense associated with this acquisition were not significant. For purposes of a preliminary allocation of the acquisition cost to assets acquired and liabilities assumed, we have assigned the excess of the acquisition cost over historical carrying values of $7 million to property, plant and equipment. This preliminary purchase price allocation is likely to change once we complete the analysis of the fair value of tangible and intangible assets acquired and liabilities assumed. Net sales and the net loss for the three months ended March 31, 2011 related to the business acquired were approximately $5 million and $(1) million, respectively.

LAFFANS ACQUISITION

On April 2, 2011, we completed the acquisition of the chemical business of Laffans Petrochemicals Limited, an amines and surfactants manufacturer located in Ankleshwar, India (the "Laffans Acquisition") at a cost of approximately $23 million. The acquired business has been integrated into our Performance Products segment. Transaction costs charged to expense related to this acquisition were not significant.

We have accounted for the Laffans Acquisition using the acquisition method. As such, we analyzed the fair value of tangible and intangible assets acquired and liabilities assumed. The allocation of acquisition cost to the assets acquired and liabilities assumed is summarized as follows (dollars in millions):

$1 million from December 31, 2011 to March 31, 2012 due to a change in the foreign currency exchange rate. All other intangible assets are being amortized over an average useful life of 18 years.

If this consolidation had occurred on January 1, 2011, the approximate pro forma revenues attributable to both our Company and Huntsman International would have been $2,709 million for the three months ended March 31, 2011. There would have been no impact to the combined earnings attributable to us or Huntsman International excluding a one-time noncash gain of approximately $12 million recognized upon consolidation included in other operating expense in the condensed consolidated statements of operations (unaudited). Upon consolidation we also recognized a one-time noncash income tax expense of approximately $2 million. The fair value of the noncontrolling interest was estimated to be $61 million at April 1, 2011. The noncontrolling interest was valued at 50% of the fair value of the net assets as of April 1, 2011, as dictated by the ownership interest percentages, adjusted for certain tax consequences only applicable to one parent.

8. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES (Continued)

A significant portion of our intercompany debt is denominated in euros. We also finance certain of our non-U.S. subsidiaries with intercompany loans that are, in many cases, denominated in currencies other than the entities' functional currency. We manage the net foreign currency exposure created by this debt through various means, including cross-currency swaps, the designation of certain intercompany loans as permanent loans because they are not expected to be repaid in the foreseeable future ("permanent loans") and the designation of certain debt and swaps as net investment hedges.

Foreign currency transaction gains and losses on intercompany loans that are not designated as permanent loans are recorded in earnings. Foreign currency transaction gains and losses on intercompany loans that are designated as permanent loans are recorded in other comprehensive loss. From time to time, we review such designation of intercompany loans.

From time to time, we review our non-U.S. dollar denominated debt and swaps to determine the appropriate amounts designated as hedges. As of March 31, 2012, we have designated €255 million (approximately $339 million) of euro-denominated debt and cross-currency interest rate swap as a hedge of our net investments. For the three months ended March 31, 2012, the amount of loss recognized on the hedge of our net investments was $13 million and was recorded as a loss in other comprehensive income. As of March 31, 2012, we had €1,223 million (approximately $1,628 million) in net euro assets.

The carrying amounts reported in our condensed consolidated balance sheets (unaudited) of cash and cash equivalents, accounts receivable and accounts payable approximate fair value because of the immediate or short-term maturity of these financial instruments. The fair value of non-qualified employee benefit plan investments is obtained through market observable pricing using prevailing market prices. The estimated fair values of our long-term debt are based on quoted market prices for the identical liability when traded as an asset in an active market.

The fair value estimates presented herein are based on pertinent information available to management as of March 31, 2012 and December 31, 2011. Although management is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since March 31, 2012, and current estimates of fair value may differ significantly from the amounts presented herein.

During the first quarter of 2012, certain U.K. pension plans were closed to new entrants. For existing participants, benefits will only grow as a result of increases in pay. Defined contribution plans were established to replace these pension plans for future benefit accruals. This change did not have a significant impact on our pension liability.

During the three months ended March 31, 2012 and 2011, we made contributions to our pension and other postretirement benefit plans of $48 million and $62 million, respectively. During the remainder of 2012, we expect to contribute an additional amount of $108 million to these plans.

SHARE REPURCHASE PROGRAM

Effective August 5, 2011, our Board of Directors authorized our Company to repurchase up to $100 million in shares of our common stock. Repurchases under this program may be made through the open market or in privately negotiated transactions, and repurchases may be commenced or suspended from time to time without prior notice. Shares of common stock acquired through the repurchase program are held in treasury at cost. During the three months ended March 31, 2012, we did not repurchase any shares of our outstanding common stock under the repurchase program. As of March 31, 2012, there remained approximately $50 million of the amount authorized under the program that could be used for stock repurchases.

COMMON STOCK DIVIDENDS

On March 30, 2012 and March 31, 2011, we paid cash dividends of $24 million, or $0.10 per share, to common stockholders of record as of March 15, 2012 and 2011, respectively.

13. COMMITMENTS AND CONTINGENCIES

LEGAL MATTERS

Asbestos Litigation

We have been named as a premises defendant in a number of asbestos exposure cases, typically claims by nonemployees of exposure to asbestos while at a facility. In the past, these cases typically have involved multiple plaintiffs bringing actions against multiple defendants, and the complaints have not indicated which plaintiffs were making claims against which defendants, where or how the alleged injuries occurred or what injuries each plaintiff claimed. These facts, which would be central to any estimate of probable loss, generally have been learned only through discovery.

Where a claimant's alleged exposure occurred prior to our ownership of the relevant premises, the prior owners generally have contractually agreed to retain liability for, and to indemnify us against, asbestos exposure claims. This indemnification is not subject to any time or dollar amount limitations. Upon service of a complaint in one of these cases, we tender it to the prior owner. Rarely do the complaints in these cases state the amount of damages being sought. The prior owner accepts responsibility for the conduct of the defense of the cases and payment of any amounts due to the claimants. In our eighteen-year experience with tendering these cases, we have not made any payment

with respect to any tendered asbestos cases. We believe that the prior owners have the intention and ability to continue to honor their indemnity obligations, although we cannot assure you that they will continue to do so or that we will not be liable for these cases if they do not.

The following table presents for the periods indicated certain information about cases for which service has been received that we have tendered to the prior owner, all of which have been accepted.

(1) Although the indemnifying party informs us when tendered cases have been resolved, it generally does not inform us of the settlement amounts relating to such cases, if any. The indemnifying party has informed us that it typically manages our defense together with the defense of other entities in such cases and resolves claims involving multiple defendants simultaneously, and that it considers the allocation of settlement amounts, if any, among defendants to be confidential and proprietary. Consequently, we are not able to provide the number of cases resolved with payment by the indemnifying party or the amount of such payments.

We have never made any payments with respect to these cases. As of March 31, 2012, we had an accrued liability of $10 million relating to these cases and a corresponding receivable of $10 million relating to our indemnity protection with respect to these cases. We cannot assure you that our liability will not exceed our accruals or that our liability associated with these cases would not be material to our financial condition, results of operations or liquidity; accordingly, we are not able to estimate the amount or range of loss in excess of our accruals. Additional asbestos exposure claims may be made against us in the future, and such claims could be material. However, because we are not able to estimate the amount or range of losses associated with such claims, we have made no accruals with respect to unasserted asbestos exposure claims as of March 31, 2012.

Certain cases in which we are a premises defendant are not subject to indemnification by prior owners or operators. The following table presents for the periods indicated certain information about

We paid gross settlement costs for asbestos exposure cases that are not subject to indemnification of $82,000 and nil during the three months ended March 31, 2012 and 2011, respectively. As of March 31, 2012, we had an accrual of $259,000 relating to these cases. We cannot assure you that our liability will not exceed our accruals or that our liability associated with these cases would not be material to our financial condition, results of operations or liquidity; accordingly, we are not able to estimate the amount or range of loss in excess of our accruals. Additional asbestos exposure claims may be made against us in the future, and such claims could be material. However, because we are not able to estimate the amount or range of losses associated with such claims, we have made no accruals with respect to unasserted asbestos exposure claims as of March 31, 2012.

Antitrust Matters

We were named as a defendant in civil class action antitrust suits alleging that between 1999 and 2004 we conspired with Bayer, BASF, Dow and Lyondell to fix the prices of MDI, TDI, polyether polyols, and related systems ("polyether polyol products") sold in the U.S. in violation of the federal Sherman Act. These cases are consolidated as the "Polyether Polyols" cases in multidistrict litigation pending in the U.S. District Court for the District of Kansas.

In addition, we and the other Polyether Polyols defendants were named as defendants in three civil antitrust suits brought by certain direct purchasers of polyether polyol products that opted out of the class certified in the Kansas multidistrict litigation. The relevant time frame for these cases is 1994 to 2004 and they are referred to as the "direct action cases." The class action and the direct action cases were consolidated in the Kansas court for the purposes of discovery and other pretrial matters.

In the second quarter of 2011, we settled the class action and were dismissed as a defendant. On December 29, 2011, we entered into a settlement agreement with the direct action plaintiffs for an amount immaterial to our financial statements and were dismissed from those cases on December 30, 2011.

Two similar civil antitrust class action cases were filed May 5 and 17, 2006 in the Superior Court of Justice, Ontario Canada and Superior Court, Province of Quebec, District of Quebec, on behalf of purported classes of Canadian direct and indirect purchasers of MDI, TDI and polyether polyols. On April 11, 2012, we reached agreement to resolve these cases for an amount immaterial to our consolidated financial statements. The Canadian settlement is subject to court approval.

A purported class action case filed February 15, 2005 by purchasers in California of products containing rubber and urethane chemicals and pending in Superior Court of California, County of San Francisco is stayed pending resolution of the Kansas multidistrict litigation. The plaintiffs in this matter make similar claims against the defendants as the class plaintiffs in the Kansas multidistrict litigation.

We have been named as a defendant in two purported class action civil antitrust suits alleging that we and our co-defendants and other co-conspirators conspired to fix prices of titanium dioxide sold in the U.S. between at least March 1, 2002 and the present. The cases were filed on February 9 and 12, 2010 in the U.S. District Court for the District of Maryland and a consolidated complaint was filed on April 12, 2010. The other defendants named in this matter are E.I. du Pont de Nemours and Company, Kronos Worldwide Inc., Millennium Inorganic Chemicals, Inc. and the National Titanium Dioxide Company Limited (d/b/a Cristal). A class certification hearing is scheduled for August 13, 2012 and trial is set to begin September 9, 2013. Discovery is ongoing.

In all of the antitrust litigation currently pending against us, the plaintiffs generally are seeking injunctive relief, treble damages, costs of suit and attorneys fees. We are not aware of any illegal conduct by us or any of our employees. Nevertheless, we have incurred costs relating to these claims and could incur additional costs in amounts material to us. As alleged damages in these cases have not been specified, and because of the overall complexity of these cases, we are unable to reasonably estimate any possible loss or range of loss with respect to these claims.

Product Delivery Claim

We have been notified by a customer of potential claims related to our allegedly delivering a different product from that which it had ordered. Our customer claims that it was unaware that the different product had been delivered until after it had been used to manufacture materials which were subsequently sold. The customer has indicated that it has been notified of claims of up to an aggregate of €153 million (approximately $200 million) relating to this matter and believes that we may be responsible for all or a portion of these potential claims. We are investigating this matter and based on the facts currently available to us, we believe that we are insured for any liability we may ultimately have in excess of $10 million. However, no assurance can be given regarding our ultimate liability or costs to us. We believe the range of possible loss to our Company in this matter to be between €0 and €153 million and have made no accrual with respect to this matter.

Other Proceedings

We are a party to various other proceedings instituted by private plaintiffs, governmental authorities and others arising under provisions of applicable laws, including various environmental, products liability and other laws. Except as otherwise disclosed in this report, we do not believe that the outcome of any of these matters will have a material effect on our financial condition, results of operations or liquidity.

14. ENVIRONMENTAL, HEALTH AND SAFETY MATTERS

ENVIRONMENTAL, HEALTH AND SAFETY MATTERS

General

We are subject to extensive federal, state, local and international laws, regulations, rules and ordinances relating to safety, pollution, protection of the environment, product management and distribution, and the generation, storage, handling, transportation, treatment, disposal and remediation of hazardous substances and waste materials. In the ordinary course of business, we are subject to frequent environmental inspections and monitoring and occasional investigations by governmental enforcement authorities. In addition, our production facilities require operating permits that are subject to renewal, modification and, in certain circumstances, revocation. Actual or alleged violations of safety laws, environmental laws or permit requirements could result in restrictions or prohibitions on plant operations or product distribution, substantial civil or criminal sanctions, as well as, under some environmental laws, the assessment of strict liability and/or joint and several liability. Moreover, changes in environmental regulations could inhibit or interrupt our operations, or require us to modify our facilities or operations. Accordingly, environmental or regulatory matters may cause us to incur significant unanticipated losses, costs or liabilities.

Environmental, Health and Safety Systems

We are committed to achieving and maintaining compliance with all applicable environmental, health and safety ("EHS") legal requirements, and we have developed policies and management systems that are intended to identify the multitude of EHS legal requirements applicable to our operations, enhance compliance with applicable legal requirements, ensure the safety of our employees, contractors, community neighbors and customers and minimize the production and emission of wastes and other pollutants. Although EHS legal requirements are constantly changing and are frequently difficult to comply with, these EHS management systems are designed to assist us in our compliance goals while also fostering efficiency and improvement and minimizing overall risk to us.

EHS Capital Expenditures

We may incur future costs for capital improvements and general compliance under EHS laws, including costs to acquire, maintain and repair pollution control equipment. For the three months ended March 31, 2012 and 2011, our capital expenditures for EHS matters totaled $19 million and $13 million, respectively. Because capital expenditures for these matters are subject to evolving regulatory requirements and depend, in part, on the timing, promulgation and enforcement of specific requirements, our capital expenditures for EHS matters have varied significantly from year to year and we cannot provide assurance that our recent expenditures are indicative of future amounts we may spend related to EHS and other applicable laws.

Remediation Liabilities

We have incurred, and we may in the future incur, liability to investigate and clean up waste or contamination at our current or former facilities or facilities operated by third parties at which we may have disposed of waste or other materials. Similarly, we may incur costs for the cleanup of waste that

was disposed of prior to the purchase of our businesses. Under some circumstances, the scope of our liability may extend to damages to natural resources.

Under the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA") and similar state laws, a current or former owner or operator of real property may be liable for remediation costs regardless of whether the release or disposal of hazardous substances was in compliance with law at the time it occurred, and a current owner or operator may be liable regardless of whether it owned or operated the facility at the time of the release. Outside the U.S., analogous contaminated property laws, such as those in effect in France and Australia, can hold past owners and/or operators liable for remediation at former facilities. We have been notified by third parties of claims against us for cleanup liabilities at approximately 10 former facilities or third party sites, including, but not limited to, sites listed under CERCLA. Based on current information and past experiences at other CERCLA sites, we do not expect any of these third party claims to have a material impact on our condensed consolidated financial statements (unaudited).

One of these sites, the North Maybe Canyon Mine CERCLA site, includes an abandoned phosphorous mine near Soda Springs, Idaho believed to have been operated by one of our predecessor companies (El Paso Products Company). In 2004, the U.S. Forest Service (the "Forest Service") notified us that we are a CERCLA potentially responsible party ("PRP") for the mine site involving selenium contaminated surface water. Under a 2004 administrative order, the current mine lessee, Nu-West Industries, Inc., began undertaking the investigation required for a CERCLA removal process. In 2008, the site was transitioned to the CERCLA remedial action process, which requires a remedial investigation/feasibility study ("RI/FS"). In 2009, the Forest Service notified the three PRPs (our Company, Nu-West and Wells Cargo) that it would undertake the RI/FS itself. On February 19, 2010, in conjunction with Wells Cargo, we agreed to jointly comply with a unilateral administrative order ("UAO") to conduct an RI/FS of a significant area of the site, although we are alleged to have had only a limited historical presence in the investigation area. In March 2010, following the initiation of litigation by Nu-West, the Forest Service assumed Nu-West's original investigation obligations. On June 15, 2010, we received the UAO which had been executed by the Forest Service and we are presently carrying out the requirements of the order. At this time, we do not believe that any loss in this matter will have a material impact on our condensed consolidated financial statements (unaudited).

In addition, under the Resource Conservation and Recovery Act ("RCRA") and similar state laws, we may be required to remediate contamination originating from our properties as a condition to our hazardous waste permit. Some of our manufacturing sites have an extended history of industrial chemical manufacturing and use, including on-site waste disposal. We are aware of soil, groundwater or surface contamination from past operations at some of our sites, and we may find contamination at other sites in the future. For example, our Port Neches, Texas, and Geismar, Louisiana, facilities are the subject of ongoing remediation requirements under RCRA authority. Similar laws exist in a number of locations in which we currently operate, or previously operated, manufacturing facilities, such as Australia, India, France, Hungary and Italy.

In June of 2006, an agreement was reached between the local regulatory authorities and our Advanced Materials site in Pamplona, Spain to relocate our manufacturing operations in order to facilitate new urban development desired by the city. Subsequently, as required by the authorities, soil

and groundwater sampling was performed and followed by a quantitative risk assessment. In October 2010, the local authorities approved our proposed two-phase remedial approach. The first phase was installed in 2011 and involves groundwater extraction and treatment in one limited area of the site. The second phase, not yet defined, would proceed during site redevelopment. As the second phase remediation has not yet been defined, we are unable to reasonably estimate any possible loss or range of loss.

By letter dated March 7, 2006, our Base Chemicals and Polymers facility in West Footscray, Australia, was issued a clean-up notice by the Environmental Protection Authority Victoria ("EPA Victoria") due to concerns about soil and groundwater contamination emanating from the site. The agency revoked the original clean-up notice on September 4, 2007 and issued a revised clean-up notice due to "the complexity of contamination issues" at the site. In the third quarter of 2009, we recorded a $30 million liability related to estimated environmental remediation costs at this site. On August 23, 2010, EPA Victoria revoked the second clean-up notice and issued a revised notice that included a requirement for financial assurance for the remediation. We have reached agreement with the agency that a mortgage on the land will be held by the agency as financial surety during the period covered by the current clean-up notice, which ends on July 30, 2014. We can provide no assurance that the agency will not seek to institute additional requirements for the site or that additional costs will not be associated with the clean up. This facility has been closed and demolished.

Environmental Reserves

We have accrued liabilities relating to anticipated environmental cleanup obligations, site reclamation and closure costs and known penalties. Liabilities are recorded when potential liabilities are either known or considered probable and can be reasonably estimated. Our liability estimates are calculated using present value techniques as appropriate and are based upon requirements placed upon us by regulators, available facts, existing technology and past experience. The environmental liabilities do not include amounts recorded as asset retirement obligations. We had accrued $36 million for environmental liabilities as of both March 31, 2012 and December 31, 2011. Of these amounts, $5 million and $7 million were classified as accrued liabilities in our condensed consolidated balance sheets (unaudited) as of March 31, 2012 and December 31, 2011, respectively, and $31 million and $29 million were classified as other noncurrent liabilities in our condensed consolidated balance sheets (unaudited) as of March 31, 2012 and December 31, 2011, respectively. In certain cases, our remediation liabilities may be payable over periods of up to 30 years.

REGULATORY DEVELOPMENTS

On June 1, 2007, the EU regulatory framework for chemicals called "REACH" took effect, designed to be phased in over 11 years. As a REACH-regulated company that manufactures in or imports more than one metric ton per year of a chemical substance into the European Economic Area, we were required to pre-register with the European Chemicals Agency ("ECHA"), such chemical substances and isolated intermediates to take advantage of the 11 year phase-in period. To meet our compliance obligations, a cross-business REACH team was established, through which we were able to fulfill all required pre-registrations and our first phase registrations by the November 30, 2010 deadline.

While we continue our registration efforts to meet the next registration deadline of June 2013, our REACH implementation team is now strategically focused on the authorization phase of the REACH process, directing its efforts to address "Substances of Very High Concern" and evaluating potential business implications. Where warranted, evaluation of substitute chemicals will be an important element of our ongoing manufacturing sustainability efforts. As a chemical manufacturer with global operations, we are also actively monitoring and addressing analogous regulatory regimes being considered or implemented outside of the EU.

Although the total long-term cost for REACH compliance is unknown at this time, we spent approximately $5 million, $9 million and $3 million in 2011, 2010 and 2009, respectively, to meet the initial REACH requirements. We cannot provide assurance that these recent expenditures are indicative of future amounts that we may be required to spend for REACH compliance.

GREENHOUSE GAS REGULATION

Although the existence of binding emissions limitations under international treaties such as the Kyoto Protocol is in doubt after 2012, we expect some or all of our operations to be subject to regulatory requirements to reduce emissions of greenhouse gases ("GHGs"). Even in the absence of a new global agreement to limit GHGs, we may be subject to additional regulation under the European Union Emissions Trading System as well as new national and regional GHG trading programs. For example, our operations in Australia and selected U.S. states may be subject to future GHG regulations under emissions trading systems in those jurisdictions.

Because the United States has not adopted federal climate change legislation, domestic GHG efforts are likely to be guided by EPA regulations in the near future. While EPA's GHG programs are currently subject to judicial challenge, our domestic operations may become subject to EPA's regulatory requirements when implemented. In particular, expansions of our existing facilities or construction of new facilities may be subject to the Clean Air Act's Prevention of Significant Deterioration Requirements under EPA's GHG "Tailoring Rule." In addition, certain aspects of our operations may be subject to GHG emissions monitoring and reporting requirements. If we are subject to EPA GHG regulations, we may face increased monitoring, reporting, and compliance costs.

We are already managing and reporting GHG emissions, to varying degrees, as required by law for our sites in locations subject to Kyoto Protocol obligations and/or EU emissions trading scheme requirements. Although these sites are subject to existing GHG legislation, few have experienced or anticipate significant cost increases as a result of these programs, although it is possible that GHG emission restrictions may increase over time. Potential consequences of such restrictions include capital requirements to modify assets to meet GHG emission restrictions and/or increases in energy costs above the level of general inflation, as well as direct compliance costs. Currently, however, it is not possible to estimate the likely financial impact of potential future regulation on any of our sites.

Finally, it should be noted that some scientists have concluded that increasing concentrations of GHG in the earth's atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, droughts, and floods and other climatic events. If any of those effects were to occur, they could have an adverse effect on our assets and operations.

INDIA INVESTIGATION

During the third quarter of 2010, we completed an internal investigation of the operations of Petro Araldite Pvt. Ltd. ("PAPL"), our majority owned joint venture in India. PAPL manufactures base liquid resins, base solid resins and formulated products in India. The investigation initially focused on allegations of illegal disposal of hazardous waste and waste water discharge and related reporting irregularities. Based upon preliminary findings, the investigation was expanded to include a review of the production and off-book sales of certain products and waste products. The investigation included the legality under Indian law and U.S. law, including the U.S. Foreign Corrupt Practices Act, of certain payments made by employees of the joint venture to government officials in India. Records at the facility covering nine months in 2009 and early 2010 show that less than $11,000 in payments were made to officials for that period; in addition, payments in unknown amounts may have been made by individuals from the facility in previous years.

In May and July 2010, PAPL fully disclosed the environmental noncompliance issues to the local Indian environmental agency, the TNPCB. All environmental compliance and reporting issues have been addressed to the agency's satisfaction other than the use of freshwater for the dilution of wastewater effluent discharges and including the remediation of several off-site solid waste disposal areas. Both remaining issues are being addressed. At TNPCB's direction, we submitted a plan for the remediation of the off-site waste disposal areas, which the TNPCB approved. The impacted off-site soil was excavated and relocated to the site. Final commercial disposal methods for the removed waste await approval from TNPCB, although we do not anticipate the costs to be material.

Also in May 2010, we voluntarily contacted the U.S. Securities and Exchange Commission ("SEC") and the DOJ to advise them of our investigation and that we intend to cooperate fully with each of them. We met with the SEC and the DOJ in October 2010 to discuss this matter and we continue to cooperate with these agencies. Steps have been taken to halt all known illegal or improper activity, including the termination of employment of management employees as appropriate.

No conclusions can be drawn at this time as to whether any government agencies will open formal investigations of these matters or what remedies such agencies may seek. Governmental agencies could assess material civil and criminal penalties and fines against PAPL and potentially against us and could issue orders that adversely affect the operations of PAPL. We cannot, however, determine at this time the magnitude of the penalties and fines that could be assessed, the total costs to remediate the prior noncompliance or the effects of implementing any necessary corrective measures on PAPL's operations.

15. STOCK-BASED COMPENSATION PLANS

Under the Huntsman Corporation Stock Incentive Plan, as amended and restated (the "Stock Incentive Plan"), a plan approved by stockholders, we may grant nonqualified stock options, incentive stock options, stock appreciation rights, restricted stock, phantom stock, performance awards and other stock-based awards to our employees, directors and consultants and to employees and consultants of our subsidiaries, provided that incentive stock options may be granted solely to employees. The terms of the grants are fixed at the grant date. As of March 31, 2012, we were authorized to grant up to 32.6 million shares under the Stock Incentive Plan. As of March 31, 2012, we had 8 million shares

Option awards have a maximum contractual term of 10 years and generally must have an exercise price at least equal to the market price of our common stock on the date the option award is granted. Stock-based awards generally vest over a three-year period.

The compensation cost from continuing operations under the Stock Incentive Plan for our Company and Huntsman International were as follows (dollars in millions):

The total income tax benefit recognized in the statements of operations for us and Huntsman International for stock-based compensation arrangements were $3 million and $2 million, respectively, for the three months ended March 31, 2012 and 2011.

STOCK OPTIONS

The fair value of each stock option award is estimated on the date of grant using the Black-Scholes valuation model that uses the assumptions noted in the following table. Expected volatilities are based on the historical volatility of our common stock through the grant date. The expected term of options granted was estimated based on the contractual term of the instruments and employees' expected exercise and post-vesting employment termination behavior. The risk-free rate for periods within the contractual life of the option was based on the U.S. Treasury yield curve in effect at the time of grant. The assumptions noted below represent the weighted average of the assumptions utilized for stock options granted during the periods.

These shares have not been reflected as vested shares in this table because, in accordance with the restricted stock unit agreements, shares of common stock are not issued for vested restricted stock units until termination of employment.

As of March 31, 2012, there was $29 million of total unrecognized compensation cost related to nonvested share compensation arrangements granted under the Stock Incentive Plan. That cost is expected to be recognized over a weighted-average period of approximately 2.2 years. The value of share awards that vested during the three months ended March 31, 2012 and 2011 was $21 million and $22 million, respectively.

16. INCOME TAXES

We use the asset and liability method of accounting for income taxes. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial and tax reporting purposes. We evaluate deferred tax assets to determine whether it is more likely than not that they will be realized. Valuation allowances are reviewed on a tax jurisdiction basis to analyze whether there is sufficient positive or negative evidence to support a change in judgment about the realizability of the related deferred tax assets for each jurisdiction. These conclusions require significant judgment. In evaluating the objective evidence that historical results provide, we consider the cyclicality of businesses and cumulative income or losses during the applicable period. Cumulative losses incurred over the applicable period limits our ability to consider other subjective evidence such as our projections for the future. Changes in expected future income in applicable jurisdictions could affect the realization of deferred tax assets in those jurisdictions. During the three months ended March 31, 2012, on a discrete basis, we changed our judgment about certain valuation allowances, primarily related to operations of the Textile Effects segment, resulting in a net $1 million expense for changes in valuation allowances related to certain net deferred tax assets in Guatemala, Indonesia and China, with no single change to a valuation allowance greater than $2 million. During the three months ended March 31, 2011, we released a valuation allowance of $5 million on certain net deferred tax assets in Luxembourg.

16. INCOME TAXES (Continued)

During the three months ended March 31, 2012, we recorded a net increase in unrecognized tax benefits with a corresponding income tax expense of $1 million and during the three months ended March 31, 2011, we recorded a net decrease in unrecognized tax benefits with a corresponding income tax benefit of $1 million, resulting from the settlement of tax audits, the effective settlement of certain tax positions and the expiration of statutes of limitations, net of additions.

During the three months ended March 31, 2012, we were granted a tax holiday for the period from January 1, 2012 through December 31, 2016 with respect to certain income from Pigments products manufactured in Malaysia. We are required to make certain investments in order to enjoy the benefits of the tax holiday and we intend to make these investments. During the three months ended March 31, 2012, we recorded a discrete benefit of $3 million from de-recognition of a net deferred tax liability that will reverse during the holiday period. The amount of tax benefit to be realized from the tax holiday is directly dependent on the amount of future pre-tax income generated. We expect that the effects of the tax holiday will not be material to our provision for income taxes.

Huntsman Corporation

Excluding the tax effects resulting from the net valuation allowance changes, the net unrecognized tax benefit items and the Malaysia tax holiday discussed above, we recorded income tax expense of $61 million and $28 million for the three months ended March 31, 2012 and 2011, respectively. Our tax expense is affected by the mix of income and losses in the tax jurisdictions in which we operate, as impacted by the presence of valuation allowances in certain tax jurisdictions.

In 2006, product defect actions were filed against our subsidiary Huntsman Chemical Company Australia Pty Limited ("HCCA") in Australian courts relating to the sale and supply of vinyl ester resins that were used in the manufacture of fiberglass swimming pools. HCCA ceased manufacturing these specific resin formulations by 2004 and sold the business that manufactured and sold these resins in 2007.

During the first quarter of 2011, HCCA increased its estimate of probable loss related to these claims and recorded a liability for the full estimated value of the claims and a corresponding receivable relating to our indemnity protection with a net charge to discontinued operations for any potential shortfall in insurance coverage. Following mediation held in August 2011, HCCA and its insurers reached an agreement with two claimants to settle their claims for amounts within our insurance coverage after our self-insured retention was satisfied. Accordingly, during the third quarter of 2011, HCCA reduced its estimate of probable loss proportionately and reversed a portion of the liability related to this matter. The settlements were paid in the fourth quarter of 2011.

18. NET INCOME PER SHARE

Basic income per share excludes dilution and is computed by dividing net income attributable to Huntsman Corporation common stockholders by the weighted average number of shares outstanding during the period. Diluted income per share reflects all potential dilutive common shares outstanding during the period and is computed by dividing net income available to Huntsman Corporation common stockholders by the weighted average number of shares outstanding during the period increased by the number of additional shares that would have been outstanding as dilutive securities.

Additional stock-based awards of 8.0 million and 7.1 million weighted average equivalent shares of stock were outstanding during the three months ended March 31, 2012 and 2011, respectively. However, these stock-based awards were not included in the computation of diluted earnings per share for the three months ended March 31, 2012 and 2011 periods because the effect would be anti-dilutive.

OVERVIEW

Business

We are a global manufacturer of differentiated organic chemical products and of inorganic chemical products. Our products comprise a broad range of chemicals and formulations, which we market globally to a diversified group of consumer and industrial customers. Our products are used in a wide range of applications, including those in the adhesives, aerospace, automotive, construction products, personal care and hygiene, durable and non-durable consumer products, electronics, medical, packaging, paints and coatings, power generation, refining, synthetic fiber, textile chemicals and dye industries. We are a leading global producer in many of our key product lines, including MDI, amines, surfactants, maleic anhydride, epoxy-based polymer formulations, textile chemicals, dyes and titanium dioxide. We had revenues for the three months ended March 31, 2012 and 2011 of $2,913 million and $2,679 million, respectively.

We operate in five segments: Polyurethanes, Performance Products, Advanced Materials, Textile Effects and Pigments.

RECENT DEVELOPMENTS

Amendment to Credit Agreement

On March 6, 2012, Huntsman International entered into a seventh amendment to the Senior Credit Facilities. The amendment among other things extended the maturity of our Revolving Facility from March 2014 to March 2017, increased capacity for revolving commitments to $400 million and extended $346 million of Term Loan B, which prior to this amendment had a maturity of April 2014, to a new stated maturity of April 2017. The amendment also increased the interest rate margin with respect to Extended Term Loan B—Series 2 to LIBOR plus 3.00%. For more information, see "Note 7. Debt—Direct and Subsidiary Debt—Amendment to Credit Agreement to our condensed consolidated financial statements (unaudited)."

OUTLOOK

During the first quarter, our Pigments segment experienced sustained sequential strength in margins and our Polyurethanes segment experienced improved margins as a result of high PO/MTBE margins (in part due to industry supply outages) and improved MDI average selling prices. We expect that PO/MTBE margins will moderate as industry supply fully recovers in the second quarter from first quarter industry outages. We believe our other businesses have strong upside potential as we see a continued recovery in the world's economy.

Demand for our products is generally sensitive to global economic growth. We expect to continue to see improving demand trends in North America, Northern Europe and through most of Asia but are cautious about demand trends in Southern Europe. We believe demand in China will continue to grow, but at a slower rate.

The following summarizes key considerations that could impact future performance of our operating segments:

We expect to spend approximately $425 million to $450 million in 2012 on capital expenditures, largely for growth initiatives and maintenance.

We expect our long-term effective income tax rate to be approximately 30% to 35%.

NM—Not Meaningful

(1) Our management uses EBITDA and Adjusted EBITDA to assess financial performance. EBITDA is defined as net income attributable to Huntsman Corporation or Huntsman International, as appropriate, before interest, income taxes, depreciation and amortization. Adjusted EBITDA is computed by eliminating the following from EBITDA: loss on early extinguishment of debt; legal settlements; EBITDA from discontinued operations; acquisition expenses; extraordinary gain on the acquisition of a business; and restructuring, impairment, plant closing and transition costs (credits).

EBITDA and Adjusted EBITDA may not necessarily be comparable to other similarly titled measures used by other companies. There are material limitations associated with our use of these measures because they do not reflect overall financial performance, including the effects of interest, income taxes, depreciation and amortization. Our management compensates for the limitations of these measures by using them as a supplement to GAAP results.

(a) Includes costs associated with the transition of our Textile Effects segment's production from Basel, Switzerland to a tolling facility. These costs were included in cost of sales in the condensed consolidated statements of operations (unaudited).

(2) Our management also uses Adjusted net income to assess financial performance. Adjusted net income is computed by eliminating the after-tax amounts related to the following from net income applicable to Huntsman Corporation or Huntsman International, as appropriate: (a) loss on early extinguishment of debt; (b) legal settlements; (c) discount amortization of settlement financing; (d) loss from discontinued operations; (e) acquisition expenses; (f) extraordinary gain on the acquisition of a business; and (g) restructuring, impairment, plant closing and transition costs. The income tax impacts of each aforementioned item was calculated using the statutory rates in the applicable taxing jurisdiction and considering valuation allowances on deferred tax assets in each jurisdiction. Basic adjusted income per share excludes dilution and is computed by dividing adjusted net income by the weighted average number of shares outstanding during the period. Diluted income per share reflects all potential dilutive common shares outstanding during the period and is computed by dividing adjusted net income by the weighted average number of shares outstanding during the period increased by the number of additional shares that would have been outstanding as dilutive securities.

Polyurethanes

The increase in revenues in our Polyurethanes segment for the three months ended March 31, 2012 compared to the same period in 2011 was due to higher average selling prices and higher sales volumes. MDI average selling prices increased primarily in response to improved demand. PO/MTBE average selling prices increased primarily in response to improved demand and industry supply constraints. MDI sales volumes increased as a result of improved demand in all regions and across all major markets with the exception of appliances. PO/MTBE sales volumes increased due to strong demand. The increase in segment EBITDA was primarily due to higher margins and higher volumes. During the three months ended March 31, 2012 and 2011, our Polyurethanes segment recorded restructuring, impairment and plant closing costs of $5 million and nil, respectively. For more information concerning restructuring activities see "Note 6. Restructuring, Impairment and Plant Closing Costs" to our condensed consolidated financial statements (unaudited).

Performance Products

The increase in revenues in our Performance Products segment for the three months ended March 31, 2012 compared to the same period in 2011 was due to higher sales volumes, partially offset by lower average selling prices. Sales volumes increased as a result of our consolidation of the Sasol-Huntsman joint venture, offset in part by lower demand for amines and surfactants. Average selling

prices decreased primarily due to the sales mix, competitive market pressures for ethyleneamines and EG and in response to lower raw material costs for certain products. The decrease in segment EBITDA was primarily due to lower margins in ethyleneamines and EG and higher manufacturing and selling, general and administrative costs.

Advanced Materials

The decrease in revenues in our Advanced Materials segment for the three months ended March 31, 2012 compared to the same period in 2011 was due to lower average selling prices, partially offset by higher sales volumes. Average selling prices decreased due to sales mix and the strength of the U.S. dollar against major international currencies. Sales volumes increased across most regions, primarily due to strong demand in our base resins business in Europe, while sales volumes in the Asia-Pacific region decreased due to lower demand in the wind energy market. The decrease in segment EBITDA was primarily due to lower margins.

Textile Effects

The decrease in revenues in our Textile Effects segment for the three months ended March 31, 2012 compared to the same period in 2011 was due to lower average selling prices. Average selling prices decreased primarily due to the strength of the U.S. dollar against major international currencies and sales mix. Sales volumes were essentially unchanged. The increase in segment EBITDA was primarily due to lower restructuring, impairment and plant closing and transition costs, partially offset by lower margins. During the three months ended March 31, 2012 and 2011, our Textile Effects segment recorded restructuring, impairment and plant closing (credits) costs of $(8) million and $5 million, respectively, and expenses of $4 million and nil, respectively, for the transition of production from Basel, Switzerland to a tolling facility. For more information concerning restructuring activities, see "Note 6. Restructuring, Impairment and Plant Closing Costs" to our condensed consolidated financial statements (unaudited).

Pigments

The increase in revenues in our Pigments segment for the three months ended March 31, 2012 compared to the same period in 2011 was due to higher average selling prices, partially offset by lower sales volumes. Average selling prices increased in all regions of the world primarily as a result of higher raw material costs. Sales volumes decreased primarily due to lower global demand and continued customer destocking, particularly in the Asia-Pacific region. The increase in segment EBITDA was primarily due to higher margins.

Corporate and other—Huntsman Corporation

Corporate and other includes unallocated corporate overhead, unallocated foreign exchange gains and losses, LIFO inventory valuation reserve adjustments, loss on early extinguishment of debt, unallocated restructuring, impairment and plant closing costs, nonoperating income and expense and gains and losses on the disposition of corporate assets. For the three months ended March 31, 2012, EBITDA from Corporate and other increased by $40 million to a loss of $41 million from a loss of $81 million for the same period in 2011. The increase in EBITDA from Corporate and other for the three months ended March 31, 2012 resulted primarily from legal settlements of $34 million during the three months ended March 31, 2011, an $11 million decrease in LIFO inventory valuation expense ($3 million of income in 2012 compared to $8 million of expense in 2011), a $5 million gain in benzene purchases during the three months ended March 31, 2012, and a $2 million decrease in loss on early extinguishment of debt ($1 million of loss in 2012 compared to $3 million of loss in 2011), and was partially offset by an increase in unallocated foreign exchange gains or losses of $5 million ($3 million loss in 2012 compared to $2 million gain in 2011).

Corporate and other—Huntsman International

Corporate and other includes unallocated corporate overhead, unallocated foreign exchange gains and losses, LIFO inventory valuation reserve adjustments, loss on early extinguishment of debt, unallocated restructuring, impairment and plant closing costs, nonoperating income and expense and gains and losses on the disposition of corporate assets. For the three months ended March 31, 2012, EBITDA from Corporate and other increased by $39 million to a loss of $41 million from a loss of $80 million for the same period in 2011. The increase in EBITDA from Corporate and other for the three months ended March 31, 2012 resulted primarily from legal settlements of $34 million during the three months ended March 31, 2011, an $11 million decrease in LIFO inventory valuation expense ($3 million of income in 2012 compared to $8 million of expense in 2011), a $5 million gain in benzene purchases during the three months ended March 31, 2012, and a $2 million decrease in loss on early extinguishment of debt ($1 million of loss in 2012 compared to $3 million of loss in 2011), and was partially offset by an increase in unallocated foreign exchange gains or losses of $5 million ($3 million loss in 2012 compared to $2 million gain in 2011). For more information regarding the loss on early extinguishment of debt, see "Note 7. Debt—Direct and Subsidiary Debt—Redemption of Notes and Loss on Early Extinguishment of Debt" to our condensed consolidated financial statements (unaudited).

Discontinued Operations

The operating results of our former polymers, base chemicals and Australian styrenics businesses are classified as discontinued operations, and, accordingly, the revenues of these businesses are excluded from revenues for all periods presented. The EBITDA of these former businesses are included in discontinued operations for all periods presented. The loss from discontinued operations represents the operating results, legal costs, restructuring, impairment and plant closing costs and gain (loss) on disposal with respect to our former businesses. The decrease in loss from discontinued operations, net of tax, resulted primarily from higher legal costs in the 2011 period. See "Note 17. Discontinued Operations" to our condensed consolidated financial statements (unaudited).

LIQUIDITY AND CAPITAL RESOURCES

The following is a discussion of our liquidity and capital resources and does not include separate information with respect to Huntsman International in accordance with General Instructions H(1)(a) and (b) of Form 10-Q.

Cash

Net cash provided by (used in) operating activities for the three months ended March 31, 2012 and 2011 was $190 million and $(124) million, respectively. The increase in net cash provided by operating activities during the three months ended March 31, 2012 compared with the same period in 2011 was primarily attributable to an increase in operating income as described in "—Results of Operations" above and to a $159 million favorable variance in operating assets and liabilities for the three months ended March 31, 2012 as compared with the same period in 2011.

Net cash used in investing activities for the three months ended March 31, 2012 and 2011 was $109 million and $57 million, respectively. During the three months ended March 31, 2012 and 2011, we paid $81 million and $60 million, respectively, for capital expenditures. During the three months ended March 31, 2012 and 2011, we made investments in Louisiana Pigments Company, L.P. of

$34 million and $6 million, respectively, and received dividends from Louisiana Pigments Company, L.P. of $15 million and $9 million, respectively.

Net cash used in financing activities for the three months ended March 31, 2012 and 2011 was $176 million and $156 million, respectively. The increase in net cash used in financing activities was primarily due to higher net repayments of debt during the 2012 period as compared to the 2011 period.

DIRECT AND SUBSIDIARY DEBT

Huntsman Corporation's direct debt and guarantee obligations consist of a guarantee of certain debt of HPS (our Chinese MDI joint venture) and certain indebtedness incurred from time to time to finance certain insurance premiums.

Substantially all of our other debt, including the facilities described below, has been incurred by our subsidiaries (primarily Huntsman International); such subsidiary debt is nonrecourse to us and we have no contractual obligation to fund our subsidiaries' respective operations.

Amendment to Credit Agreement

On March 6, 2012, Huntsman International entered into a seventh amendment to its Senior Credit Facilities. Among other things, the amendment:

The amendment provides that, notwithstanding the stated maturity date, the termination date of the Revolving Facility commitments will accelerate if we do not repay, refinance or have a minimum level of liquidity available to enable us to repay our 5.50% senior notes due 2016, Term Loan B due April 19, 2014 and Term Loan C due June 30, 2016. Extended Term Loan B—Series 2 will accelerate if we do not repay or have a minimum level of liquidity available to enable us to repay our 5.50% senior notes due 2016 that remain outstanding during the three months prior to the maturity date of such notes. Extended Term Loan B—Series 2 will amortize in an amount equal to 1% of the principal amount, payable annually commencing on March 31, 2013.

Senior Credit Facilities

As of March 31, 2012, our Senior Credit Facilities consisted of our Revolving Facility, our Term Loan B, our Term Loan C, our Extended Term Loan B and our Extended Term Loan B—Series 2 as follows (dollars in millions):

(2) The applicable interest rate of the Senior Credit Facilities is subject to certain secured leverage ratio thresholds. As of March 31, 2012, the weighted average interest rate on our outstanding balances under the Senior Credit Facilities was approximately 3%. (3) The maturity of the Revolving Facility commitments will accelerate if we do not repay, refinance or have a minimum level of liquidity available to enable us to repay our 5.50% senior notes due 2016, Term Loan B due April 19, 2014 and Term Loan C due June 30, 2016. The maturity of Extended Term Loan B and Extended Term Loan B—Series 2 will accelerate if we do not repay, refinance or have a minimum level of liquidity available to enable us to refinance or repay our 5.50% senior notes due 2016 that remain outstanding during the three months prior to the maturity date of such notes.

Our obligations under the Senior Credit Facilities are guaranteed by our guarantor subsidiaries, which consist of substantially all of our domestic subsidiaries and certain of our foreign subsidiaries, and are secured by a first priority lien on substantially all of our domestic property, plant and equipment, the stock of all of our material domestic subsidiaries and certain foreign subsidiaries and pledges of intercompany notes between certain of our subsidiaries.

Redemption of Notes and Loss on Early Extinguishment of Debt

During the three months ended March 31, 2012 and 2011, we redeemed or repurchased the following notes (monetary amounts in millions):

Other Debt

On March 30, 2012, we repaid the remaining A$26 million (approximately $27 million) outstanding under our Australian Credit Facility, which represents repayment of A$14 million (approximately $15 million) under the revolving facility and A$12 million (approximately $12 million) under the term loan facility.

Note Payable from Huntsman International to Huntsman Corporation

As of March 31, 2012, we have a loan of $637 million to our subsidiary, Huntsman International. During the quarter ended March 31, 2012, Huntsman International borrowed $102 million from us under the Intercompany Note. The Intercompany Note is unsecured and $100 million of the outstanding amount is classified as current as of both March 31, 2012 and December 31, 2011 on the condensed consolidated balance sheets (unaudited). As of March 31, 2012, under the terms of the Intercompany Note, Huntsman International promises to pay us interest on the unpaid principal amount at a rate per annum based on the previous monthly average borrowing rate obtained under our U.S. A/R Program, less ten basis points (provided that the rate shall not exceed an amount that is 25 basis points less than the monthly average borrowing rate obtained for the U.S. LIBOR-based borrowings under our Revolving Facility).

COMPLIANCE WITH COVENANTS

We believe that we are in compliance with the covenants contained in the agreements governing our material debt instruments, including our Senior Credit Facilities, our A/R Programs and our notes.

Our material financing arrangements contain certain covenants with which we must comply. A failure to comply with a covenant could result in a default under a financing arrangement if not waived or amended. A default under these material financing arrangements generally allows debt holders the option to declare the underlying debt obligations immediately due and payable.

Furthermore, certain of our material financing arrangements contain cross default and cross acceleration provisions under which a failure to comply with the covenants in one financing arrangement may result in an event of default under another financing arrangement.

Our Senior Credit Facilities are subject to a single financial covenant which applies only to the Revolving Facility and is tested at the Huntsman International level. The Leverage Covenant is applicable only if borrowings, letters of credit or guarantees are outstanding under the Revolving Facility (cash collateralized letters of credit or guarantees are not deemed outstanding). The Leverage Covenant is a net senior secured leverage ratio covenant which requires that Huntsman International's ratio of senior secured debt to EBITDA (as defined in the applicable agreement) is not more than 3.75 to 1.

If in the future Huntsman International fails to comply with the Leverage Covenant, then we may not have access to liquidity under our Revolving Facility. If Huntsman International failed to comply with the Leverage Covenant at a time when we had uncollateralized loans or letters of credit outstanding under the Revolving Facility, Huntsman International would be in default under the Senior Credit Facilities, and, unless Huntsman International obtained a waiver or forbearance with respect to such default (as to which we can provide no assurance), Huntsman International could be required to pay off the balance of the Senior Credit Facilities in full, and we may not have further access to such facilities.

The agreements governing our A/R Programs also contain certain receivable performance metrics. Any material failure to meet the applicable A/R Programs' metrics in the future could lead to an early termination event under the A/R Programs, which could require us to cease our use of such facilities, prohibiting us from additional borrowings against our receivables or, at the discretion of the lenders, requiring that we repay the A/R Programs in full. An early termination event under the A/R Programs would also constitute an event of default under our Senior Credit Facilities, which could require us to pay off the balance of the Senior Credit Facilities in full and could result in the loss of our Senior Credit Facilities.

SHORT-TERM AND LONG-TERM LIQUIDITY

We depend upon our cash, credit facilities, A/R Programs and other debt instruments to provide liquidity for our operations and working capital needs. As of March 31, 2012, we had $1,109 million of combined cash and unused borrowing capacity, consisting of $478 million in cash and restricted cash, $381 million in availability under our Revolving Facility, and $250 million in availability under our A/R Programs. Our liquidity can be significantly impacted by various factors. The following matters had, or are expected to have, a significant impact on our liquidity:

Table of Contents

As of March 31, 2012, we had $193 million classified as current portion of debt which consists of certain scheduled term payments and various short-term facilities including an HPS borrowing facility in China with $79 million outstanding, our scheduled Senior Credit Facilities amortization payments totaling $31 million, scheduled amortization payments at our VIEs of $23 million and certain other short term facilities and scheduled amortization payments totaling $60 million. Although we cannot provide assurances, we intend to renew or extend the majority of these short-term facilities in the current period.

As of March 31, 2012, we had approximately $217 million of cash and cash equivalents, including restricted cash, held by our foreign subsidiaries, including our VIEs. Additionally, we have material intercompany debt obligations owed to us by our non-U.S. subsidiaries. We intend to use cash held in our foreign subsidiaries to fund our local operations. Nevertheless, we could repatriate cash as dividends or as repayments of intercompany debt. If foreign cash were repatriated as dividends, the dividends could be subject to adverse tax consequences. At present, we estimate that we will generate sufficient cash in our U.S. operations, together with the payments of intercompany debt if necessary, to meet our cash needs in the U.S and we do not expect to repatriate material cash to the U.S. as dividends in the near term. Cash held by certain foreign subsidiaries, including our VIEs, may also be subject to legal restrictions, including those arising from the interests of our partners, which could limit the amounts available for repatriation.

RESTRUCTURING, IMPAIRMENT AND PLANT CLOSING COSTS

Our Polyurethanes, Advanced Materials, Textile Effects and Pigments segments are involved in cost reduction programs that are expected to reduce costs in these businesses by approximately $190 million. These cost savings are expected to be achieved through the third quarter of 2013. For further

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risks, such as changes in interest rates, foreign exchange rates and commodity pricing risks. From time to time, we enter into transactions, including transactions involving derivative instruments, to manage certain of these exposures.

All derivatives, whether designated in hedging relationships or not, are recorded on our balance sheet at fair value. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and the hedged items are recognized in earnings. If the derivative is designated as a cash flow hedge, changes in the fair value of the derivative are recorded in accumulated other comprehensive loss, to the extent effective, and will be recognized in the income statement when the hedged item affects earnings. To the extent applicable, we perform effectiveness assessments in order to use hedge accounting at each reporting period. For a derivative that does not qualify as a hedge, changes in fair value are recognized in earnings.

We also hedge our net investment in certain European operations. Changes in the fair value of the hedge in the net investment of certain European operations are recorded in accumulated other comprehensive loss.

Our cash flows and earnings are subject to fluctuations due to exchange rate variation. Our revenues and expenses are denominated in various foreign currencies. From time to time, we may enter into foreign currency derivative instruments to minimize the short-term impact of movements in foreign currency rates. Where practicable, we generally net multicurrency cash balances among our subsidiaries to help reduce exposure to foreign currency exchange rates. Certain other exposures may be managed from time to time through financial market transactions, principally through the purchase of spot or forward foreign exchange contracts (generally with maturities of one year or less). We do not hedge our foreign currency exposures in a manner that would eliminate the effect of changes in exchange rates on our cash flows and earnings. As of March 31, 2012, we had approximately $226 million in notional amount (in U.S. dollar equivalents) outstanding in forward foreign currency contracts.

On December 9, 2009, we entered into a five-year interest rate contract to hedge the variability caused by monthly changes in cash flow due to associated changes in LIBOR under our Senior Credit Facilities. The notional value of the contract is $50 million, and it has been designated as a cash flow hedge. The effective portion of the changes in the fair value of the swap was recorded in other comprehensive loss. We will pay a fixed 2.6% on the hedge and receive the one-month LIBOR rate. As of March 31, 2012, the fair value of the hedge was $3 million and was recorded in other noncurrent liabilities on the condensed consolidated balance sheets (unaudited).

On January 19, 2010, we entered into an additional five-year interest rate contract to hedge the variability caused by monthly changes in cash flow due to associated changes in LIBOR under our Senior Credit Facilities. The notional value of the contract is $50 million, and it has been designated as a cash flow hedge. The effective portion of the changes in the fair value of the swap was recorded as other comprehensive income. We will pay a fixed 2.8% on the hedge and receive the one-month LIBOR rate. As of March 31, 2012, the fair value of the hedge was $3 million and was recorded in other noncurrent liabilities on the condensed consolidated balance sheets (unaudited).

On September 1, 2011, we entered into a $50 million forward interest rate contract that will begin in December 2014 with maturity in April 2017 and a $50 million forward interest rate contract that will begin in January 2015 with maturity in April 2017. These two forward contracts are to hedge the variability caused by monthly changes in cash flow due to associated changes in LIBOR under our Senior Credit Facilities once our existing interest rate hedges mature. These swaps are designated as cash flow hedges and the effective portion of the changes in the fair value of the swaps were recorded in other comprehensive income. Both interest rate contracts will pay a fixed 2.5% on the hedge and receive the one-month LIBOR rate once the contracts begin in 2014 and 2015, respectively. As of March 31, 2012, the combined fair value of these two hedges was $1 million and was recorded in other noncurrent liabilities on the condensed consolidated balance sheets (unaudited).

In 2009, Sasol-Huntsman entered into derivative transactions to hedge the variable interest rate associated with its local credit facility. These hedges include a floating to fixed interest rate contract providing Sasol-Huntsman with EURIBOR interest payments for a fixed payment of 3.62% and a cap for future periods with a strike price of 3.62%. In connection with the consolidation of Sasol-Huntsman as of April 1, 2011, the interest rate contract is now included in our consolidated results. See "Note 5. Variable Interest Entities" to our condensed consolidated financial statements (unaudited). The notional amount of the hedge as of March 31, 2012 was €51 million (approximately $67 million) and the derivative transactions do not qualify for hedge accounting. As of March 31, 2012, the fair value of this hedge was €3 million (approximately $4 million) and was recorded in other noncurrent liabilities on the condensed consolidated balance sheets (unaudited). For the three months ended March 31, 2012, we recorded interest expense of less than €1 million (less than $1 million) due to changes in the fair value of the swap.

Beginning in 2009, Arabian Amines Company entered into a 12-year floating to fixed interest rate contract providing for a receipt of LIBOR interest payments for a fixed payment of 5.02%. In connection with the consolidation of Arabian Amines Company as of July 1, 2010, the interest rate contract is now included in our consolidated results. See "Note 5. Variable Interest Entities" to our condensed consolidated financial statements (unaudited). The notional amount of the swap as of March 31, 2012 was $38 million, and the interest rate contract is not designated as a cash flow hedge. As of March 31, 2012, the fair value of the swap was $6 million and was recorded as other noncurrent liabilities on the condensed consolidated balance sheets (unaudited). For the three months ended March 31, 2012, we recorded a reduction of interest expense of less than $1 million due to changes in the fair value of the swap.

In conjunction with the issuance of 8.625% senior subordinated notes due 2020, we entered into cross-currency interest rate contracts with three counterparties. On March 17, 2010, we paid $350

million to these counterparties and received €255 million from these counterparties and at maturity on March 15, 2015 we are required to pay €255 million and will receive $350 million. On March 15 and September 15 of each year, we will receive U.S. dollar interest payments of approximately $15 million (equivalent to an annual rate of 8.625%) and make interest payments of approximately €11 million (equivalent to an annual rate of approximately 8.41%). This swap is designated as a hedge of net investment for financial reporting purposes. As of March 31, 2012, the fair value of this swap was $17 million and was recorded in noncurrent assets in our condensed consolidated balance sheets (unaudited).

As of and for the three months ended March 31, 2012, the changes in fair value of the realized gains (losses) recorded in the condensed consolidated statements of operations (unaudited) of our other outstanding foreign currency rate hedging contracts and derivatives were not considered significant.

A significant portion of our intercompany debt is denominated in euros. We also finance certain of our non-U.S. subsidiaries with intercompany loans that are, in many cases, denominated in currencies other than the entities' functional currency. We manage the net foreign currency exposure created by this debt through various means, including cross-currency swaps, the designation of certain intercompany loans as permanent loans because they are not expected to be repaid in the foreseeable future and the designation of certain debt and swaps as net investment hedges.

Foreign currency transaction gains and losses on intercompany loans that are not designated as permanent loans are recorded in earnings. Foreign currency transaction gains and losses on intercompany loans that are designated as permanent loans are recorded in other comprehensive loss. From time to time, we review such designation of intercompany loans.

From time to time, we review our non-U.S. dollar denominated debt and swaps to determine the appropriate amounts designated as hedges. As of March 31, 2012, we have designated €255 million (approximately $339 million) of euro-denominated debt and cross-currency interest rate swap as a hedge of our net investments. For the three months ended March 31, 2012, the amount of loss recognized on the hedge of our net investments was $13 million and was recorded as a loss in other comprehensive income. As of March 31, 2012, we had €1,223 million (approximately $1,628 million) in net euro assets.

ITEM 4. CONTROLS AND PROCEDURES

Our management, with the participation of our chief executive officer and chief financial officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of March 31, 2012. Based on this evaluation, our chief executive officer and chief financial officer have concluded that, as of March 31, 2012, our disclosure controls and procedures were effective, in that they ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is (1) recorded, processed, summarized and reported within the time periods specified in the Commission's rules and forms, and (2) accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

No changes to our internal control over financial reporting occurred during the quarter ended March 31, 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). However, we can only give reasonable assurance that our internal controls over financial reporting will prevent or detect material misstatements on a timely basis. Ineffective internal controls over financial reporting could cause investors to lose confidence in our reported financial information and could result in a lower trading price for our securities.
