2. ACCOUNTING STANDARDS

RECENTLY ADOPTED ACCOUNTING STANDARD

On* January 1, 2025,we adopted Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU)No. 2023-09, Income Taxes (Topic740): Improvements to Income Tax Disclosures*; however, the required disclosures are effective for our2025 annual reporting period and interim reporting periods within fiscal years beginning after* December 15, 2025.*We are currently evaluating the impact of the adoption of this accounting standard on the related disclosures.

ACCOUNTING STANDARDS PENDING ADOPTION IN FUTURE PERIODS

The following relevant accounting standards become effective subsequent to fiscal year2025, and we are currently evaluating the impact of the future adoption of these accounting standards on our financial statements and related disclosures:

3. BUSINESS COMBINATIONS AND ACQUISITIONS

SEPARATION AND ACQUISITION OF ASSETS OF SLIC JOINT VENTURE

On* January 31, 2024,we completed the planned separation and acquisition of assets of Shanghai Lianheng Isocyanate Company Ltd. (“SLIC”), our former joint venture with BASF andthree* Chinese chemical companies. The final purchase price of the acquired assets was determined based on an asset valuation that was completed in thesecond quarter of2024. The acquisition of the assets was funded in part with Huntsman Polyurethanes Shanghai Ltd., our70%-owned consolidated joint venture in China (“HPS”), issuing a U.S. dollar equivalent note payable at closing of approximately $218 million, which was repaid in full in thesecond quarter of2024 using available funds at HPS. During thethird quarter of2024, we received approximately $64 million of cash from SLIC, of which $34 million was a dividend and $30 million was an interim liquidating distribution. Upon the full liquidation of the joint venture during thefirst quarter of2025, all remaining cash of SLIC, primarily resulting from the proceeds received by SLIC, was distributed back to the joint venture partners. As such, during thefirst quarter of2025, we received approximately $41 million of cash from SLIC, which was our final liquidating distribution.

The acquisition has been integrated into our Polyurethanes segment. Transaction costs related to this acquisition werenot material during2024.

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

The total fair value of the net assets acquired was in excess of the acquisition cost resulting in net gains of approximately $51 million recognized during2024 and approximately $5 million recognized during thefirst quarter of2025. Concurrent with the acquisition of net assets, we wrote off certain prepaid assets of approximately $71 million during2024 related to operating agreements with SLIC and other joint venture partners.

According to the operating agreement of the joint venture, SLIC sold all of its output to the joint venture partners withno external sales. After the separation and acquisition of assets, we use all of the output of the acquired assets for internal use. As such, the acquired business hasno external revenues or net income.

7. SUPPLIER FINANCE PROGRAM

During thefirst quarter of2025, we initiated a supplier finance program that has been made available to certain of our vendors. The program allows our vendors to voluntarily sell their receivables due from us to a participating financial institution on terms that are negotiated between the vendor and the financial institution. The vendor receives payment from the financial institution, and we pay the financial institution on the terms originally negotiated with the vendor, which generally range from 90 to 120 days. We donot pledge assets as security or provide other forms of guarantees associated with this supplier finance program. As of* September 30, 2025*, outstanding obligations confirmed as valid under this supplier finance program were approximately $41 million, which are included inaccounts payable in our condensed consolidated balance sheets.

8. RESTRUCTURING, IMPAIRMENT AND PLANT CLOSING COSTS

As of* September 30, 2025* and* December 31, 2024*, accrued restructuring and plant closing costs by type of cost consisted of the following (dollars in millions):

Details with respect to cash and noncash restructuring, impairment and plant closing costs from continuing operations for thethree andnine months ended* September 30, 2025and2024* are provided below (dollars in millions):

Restructuring Activities

Beginning in thesecond quarter of2025, our Performance Products segment implemented a restructuring program to close its European maleic anhydride manufacturing facility in Moers, Germany and to reduce other organizational structure costs. During thethird quarter of2025, this program was further expanded for additional site closure costs. In connection with this restructuring program, we recorded net restructuring expense of approximately $92 million for thenine months ended* September 30, 2025*, primarily related to workforce reductions, contract terminations and approximately $81 million for the impairment of assets, including approximately $14 million of goodwill, related to the closure of the facility. We expect to record further restructuring expenses of approximately $2 million through thefirst quarter of2026, primarily related to a site closure.

Beginning in thefourth quarter of2024, our Polyurethanes segment implemented a restructuring program to reduce organizational structure costs. During thesecond quarter of2025, this program was further expanded to optimize its European business organization. In connection with this restructuring program, we recorded net restructuring expense of approximately $45 million for thenine months ended* September 30, 2025*, primarily related to workforce reductions and accelerated depreciation. We expect to record further restructuring expenses of approximately $16 million through2027, primarily related to workforce reductions, accelerated depreciation and site closures.

19

Beginning in thefirst quarter of2024, our Advanced Materials segment implemented a restructuring program to optimize the segment’s manufacturing processes and cost structure in the U.S. to better align with future market opportunities. In connection with this restructuring program, we recorded net restructuring expense of approximately $1 million and $12 million during thenine months ended* September 30, 2025and2024*, respectively, primarily related to accelerated depreciation and workforce reductions. We expect to record further restructuring expenses of approximately $6 million through2027, primarily related to accelerated depreciation and workforce reductions.

Beginning in thefourth quarter of2022, we implemented a restructuring program to further realign our cost structure with additional restructuring in Europe. This program was associated with all of our segments and included exiting and consolidating certain facilities, workforce relocation to lower cost locations and further personnel rationalization. In connection with this restructuring program, we recorded a credit of approximately $2 million during thenine months ended* September 30, 2025* to adjust the restructuring reserve that wasno longer required, and we recorded net restructuring expense of approximately $4 million during thenine months ended* September 30, 2024*, primarily related to site closures.

9. DEBT

​

Our outstanding debt, net of debt issuance costs, of consolidated entities consisted of the following (dollars in millions):

​

​

Direct and Subsidiary Debt

​

Substantially all of our debt, including the facilities described below, has been incurred by our subsidiaries (primarily Huntsman International). Huntsman Corporation isnot a guarantor of such subsidiary debt.

​

Certain of our subsidiaries havethird-party debt agreements that contain certain restrictions with regard to dividends, distributions, loans or advances. In certain circumstances, the consent of athird party would be required prior to the transfer of any cash or assets from these subsidiaries to us.

​

Revolving Credit Facility

On* May 20, 2022,Huntsman International entered into a $1.2 billion senior unsecured revolving credit facility (as amended, the“2022* Revolving Credit Facility”). Borrowings bear interest at the rates specified in the credit agreement governing the2022 Revolving Credit Facility, which vary based on the type of loan and Huntsman International’s debt ratings. Under the credit agreement, the interest rate margin and the commitment fee rates are also subject to adjustments based on the Company’s performance on specified sustainability target thresholds with respect to annual percentage reduction in operational greenhouse gas emissions intensity and annual percentage reduction in water consumption intensity. Unless previously terminated in accordance with its terms, the2022 Revolving Credit Facility will mature in* May 2027.Huntsman International mayincrease the2022* Revolving Credit Facility commitments up to an additional $500 million, subject to the satisfaction of certain conditions.

On* May 23, 2025,Huntsman International entered into a Second Amendment to the2022* Revolving Credit Facility (the “Second Amendment”). The Second Amendment amends the financial covenant regarding the leverage ratio of Huntsman International and its subsidiaries to increase the maximum permitted ratio of Consolidated Net Debt to Consolidated EBITDA (as those terms are defined in the2022 Revolving Credit Facility) through the quarter ending* December 31, 2026,*or earlier if elected by Huntsman International after demonstrating compliance with a certain ratio of Consolidated Net Debt to Consolidated EBITDA (such period, the “Covenant Relief Period”).

The Second Amendment also (i) reduces the general debt and liens baskets during the Covenant Relief Period and (ii) amends the restricted payments covenant to limit Huntsman International’s ability to make restricted payments for the purpose of providing Huntsman Corporation funds to redeem its equity interests during the Covenant Relief Period, subject to certain exceptions.

20

The following table presents certain amounts under our2022 Revolving Credit Facility as of* September 30, 2025* (monetary amounts in millions):

Senior Notes

On* March 28, 2025,we satisfied and discharged our obligations under the indenture governing our 4.25% senior notes due April 2025 (**“2025* Senior Notes”) by irrevocably depositing funds sufficient to redeem them in full, which was approximately $315 million, on the maturity date of* April 1, 2025.*

As of* September 30, 2025*, our senior notes consisted of the following (monetary amounts in millions):

A/R Programs

​

Our U.S. accounts receivable securitization program (“U.S. A/R Program”) and our European accounts receivable securitization program (“EU A/R Program” and collectively with the U.S. A/R Program, “A/R Programs”) are structured so that we transfer certain of our trade receivables to the U.S. special purpose entity (“U.S. SPE”) and the European special purpose entity (“EU SPE”) in transactions intended to be true sales or true contributions. The receivables collateralize debt incurred by the U.S. SPE and the EU SPE.

Information regarding our A/R Programs as of* September 30, 2025* was as follows (monetary amounts in millions):

​

​

​

​

As of* September 30, 2025* and* December 31, 2024*, $275 million and $233 million, respectively, of accounts receivable were pledged as collateral under our A/R Programs.

21

Variable Interest Entity Debt

As of* September 30, 2025*, AAC, our consolidated 50%-owned joint venture, had $9 million outstanding under its loan commitments and debt financing arrangements, all of which was classified as current debt on our condensed consolidated balance sheets. We donot guarantee these loan commitments, and AAC isnot a guarantor of any of our other debt obligations.

Debt Issuance Costs

​

We record debt issuance costs related to a debt liability on the balance sheets as a reduction to the face amount of that debt liability. As of* September 30, 2025* and* December 31, 2024*, the amount of debt issuance costs directly reducing the debt liability was $8 million and $9 million, respectively. We amortize debt issuance costs using either a straight line or effective interest method, depending on the debt agreement, and record them as interest expense.​

Compliance with Covenants

​

Our2022 Revolving Credit Facility contains a financial covenant regarding the leverage ratio of Huntsman International and its subsidiaries. The2022 Revolving Credit Facility also contains other customary covenants and events of default for credit facilities of this type. Upon an event of default that isnot cured or waived within any applicable cure periods, in addition to other remedies that* maybe available to the lenders, the obligations under the2022* Revolving Credit Facility* may*be accelerated.

The agreements governing our A/R Programs also contain certain receivable performance metrics. Any material failure to meet the applicable A/R Programs’ metrics 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 our2022 Revolving Credit Facility, which could require us to pay off the balance of the2022 Revolving Credit Facility in full and could result in the loss of our2022 Revolving Credit Facility.

We believe that we are in compliance with the covenants contained in the agreements governing our material debt instruments, including our2022 Revolving Credit Facility, our A/R Programs and our senior notes.​

10. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

​

We are exposed to market risks, such as changes in interest rates, foreign exchange rates and commodity prices. From time to time, we enter into transactions, including transactions involving derivative instruments, to manage certain of these exposures. We also hedge our net investment in certain European operations. Changes in the fair value of the hedge of our net investment in certain European operations are recorded in accumulated other comprehensive loss.

​

Through our borrowing activities, we are exposed to interest rate risk. Such risk arises due to the structure of our debt portfolio, including the mix of fixed and floating interest rates. Actions taken to reduce interest rate risk include managing the mix and rate characteristics of various interest-bearing liabilities, as well as entering into interest rate derivative instruments. From time to time, we* may*purchase interest rate swaps and/or other derivative instruments to reduce the impact of changes in interest rates on our floating-rate exposures. Under interest rate swaps, we agree with other parties to exchange, at specified intervals, the difference between fixed-rate and floating-rate interest amounts calculated by reference to an agreed notional principal amount.

Our revenues and expenses are denominated in various foreign currencies, and our cash flows and earnings are thus subject to fluctuations due to exchange rate variations. From time to time, we* mayenter 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 maybe managed from time to time through financial market transactions, principally through the purchase of spot or forward foreign exchange contracts (generally with maturities ofone year or less). We donot* 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* September 30, 2025and2024*, we had approximately $127 million and $81 million, respectively, of notional amount (in U.S. dollar equivalents) outstanding in forward foreign currency contracts related to continuing operations.

We review our non-U.S. dollar denominated debt and derivative instruments to determine the appropriate amounts designated as hedges. As of* September 30, 2025*, we have designated approximately€266 million (approximately $311 million) of euro-denominated derivative instruments as a hedge of our net investment. For thenine months ended* September 30, 2025and2024*, the amounts recognized on the hedge of our net investment were losses of approximately $41 million and gains of approximately $2 million, respectively, and were recorded in other comprehensive income in our condensed consolidated statements of comprehensive (loss) income.​

During thethird quarter of2024, we entered intothree-year, cross-currency interest rate contracts to swap an aggregate notional amount $350 million for an approximate aggregate notional€315 million. These cross-currency swaps are designated as net investment hedges and designed to hedge the foreign currency exposure of our net investment in certain European operations. Changes in fair value are recorded in accumulated other comprehensive loss to offset the foreign currency translation adjustments related to these investments. As of* September 30, 2025*, the fair value of these swaps was a liability of approximately $22 million.

22

11. FAIR VALUE

​

The fair values of our financial instruments were as follows (dollars in millions):

​

​

The carrying amounts reported in the balance sheets 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 values of non-qualified employee benefit plan investments are obtained through market observable pricing using prevailing market prices (Level1). The fair values of our cross-currency interest rate contracts are based on observable inputs other than quoted prices (Level2). The fair values of our senior notes are based on quoted market prices for the identical liability when traded in an active market (Level1), and the fair values of all our other outstanding debt are based on observable inputs other than quoted prices (Level2). The fair value estimates presented herein are based on pertinent information available to management as of* September 30, 2025* and* December 31, 2024*. Although we arenot aware of any factors that would significantly affect the estimated fair value amounts, such amounts havenot been comprehensively revalued for purposes of these financial statements since* September 30, 2025*, and current estimates of fair value* may*differ significantly from the amounts presented herein.

​

During thenine months ended* September 30, 2025*, we heldno instruments measured at fair value on a recurring basis using significant unobservable inputs (Level3), and there wereno gains or losses (realized and unrealized) included in our earnings for instruments categorized as Level3 within the fair value hierarchy.

13. EMPLOYEE BENEFIT PLANS

​

Components of the net periodic benefit cost from continuing operations for thethree andnine months ended* September 30, 2025and2024* were as follows (dollars in millions):

​

During thenine months ended* September 30, 2025and2024*, we made contributions to our pension and other postretirement benefit plans related to continuing operations of $25 million and $26 million, respectively. During the remainder of2025, we expect to make additional contributions of approximately $9 million to these plans.

​

14. HUNTSMAN CORPORATION STOCKHOLDERS’ EQUITY

​

Share Repurchase Program

​

On* October 26, 2021,our Board of Directors approved a new share repurchase program of $1 billion. On March 25, 2022,our Board of Directors increased the authorization of our share repurchase program from $1 billion to $2 billion. The share repurchase program is supported by our free cash flow generation. Repurchases maybe made in the open market, including through accelerated share repurchase programs, or in privately negotiated transactions. Shares of common stock acquired through the repurchase program are held in treasury at cost. The Second Amendment to our2022* Revolving Credit Facility limits Huntsman International’s ability to make restricted payments to Huntsman Corporation for the purpose of repurchasing shares while the Second Amendment is in effect. During thenine months ended* September 30, 2025*, we didnot repurchase any shares of our common stock under this program. As of* September 30, 2025*, we have approximately $547 million remaining under the authorization of our existing share repurchase program.

​

Dividends on Common Stock

​

During both of thethree months ended* September 30, 2025and2024*, we declared dividends of $44 million, or $0.25 per share, to common stockholders. During thethree months ended* June 30, 2025and2024,* we declared dividends of $44 million and $43 million, respectively, or $0.25 per share, to common stockholders. During thethree months ended* March 31, 2025and2024,* we declared dividends of $44 million and $43 million, respectively, or$0.25 per share, to common stockholders.

16. COMMITMENTS AND CONTINGENCIES

​

Legal Matters

​

On* February 6, 2025,the Louisiana Supreme Court affirmed the jury verdict and district court judgment in our favor in our long-running court battle against Praxair/Linde,one of the industrial gas suppliers to our Geismar, Louisiana MDI manufacturing site, and entered a damages award consistent with Huntsman’s expert witness testimony at trial. The case was filed after Praxair refused to maintain properly its own Geismar facility and then repeatedly failed to supply our requirements for industrial gases needed to manufacture MDI under long-term supply contracts that expired in2013.* During thefirst quarter of2025, we received a final award of approximately $66 million, which included mandatory pre-judgment and post-judgment interest of approximately $23.5 million. We recognized income related to this matter of approximately $33 million, net of legal fees, during thefirst quarter of2025. We expect to pay cash taxes related to this matter of approximately $8 million in future years.

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. We donot believe that the outcome of any of these matters will have a material effect on our financial condition, results of operations or liquidity.

17. ENVIRONMENTAL, HEALTH AND SAFETY MATTERS

​

EHSC apital Expenditures

We* mayincur future costs for capital improvements and general compliance under environmental, health and safety (“EHS”) laws, including costs to acquire, maintain and repair pollution control equipment. For thenine* months ended* September 30, 2025and2024*, our capital expenditures from continuing operations for EHS matters totaled $26 million and $18 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.

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 donot include amounts recorded as asset retirement obligations. We had accrued $16 million and $15 million for environmental liabilities as of* September 30, 2025* and* December 31, 2024*, respectively. Of these amounts, $10 million and $6 million were classified as accrued liabilities as of* September 30, 2025* and* December 31, 2024*, respectively, and $6 million and $9 million were classified as other noncurrent liabilities as of* September 30, 2025* and* December 31, 2024*, respectively. In certain cases, our remediation liabilities* maybe payable over periods of up to 30 years. We mayincur losses for environmental remediation in excess of the amounts accrued; however, we arenot* able to estimate the amount or range of such potential excess.

Environmental Matters

​

Under the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”) and similar state laws, a current or former owner or operator of real property in the U.S.* maybe 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 maybe liable regardless of whether it owned or operated the facility at the time of the release. Outside the U.S., analogous contaminated property laws can hold past owners and/or operators liable for remediation at former facilities. Currently, there are approximatelysix former facilities orthird*-party sites in the U.S. for which we have been notified of potential claims against us for cleanup liabilities, including, butnot limited to, sites listed under CERCLA. Based on current information and past experiences at other CERCLA sites, we donot expect thesethird-party claims to have a material impact on our condensed consolidated financial statements.

​

Under the Resource Conservation and Recovery Act (“RCRA”) in the U.S. and similar state laws, we* maybe required to remediate contamination originating from our properties. Similar laws exist in a number of non-U.S. locations in which we currently operate, or previously operated, manufacturing facilities. 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 Geismar, Louisiana facility is the subject of ongoing remediation requirements imposed under RCRA.

18. STOCK-BASED COMPENSATION PLANS

​

On* April 30, 2025,our stockholders approved a new Huntsman Corporation2025* Stock Incentive Plan (the*‘‘2025* Stock Incentive Plan’’), which reserved 4.65 million shares for issuance. Each of the Huntsman Corporation2016 Stock Incentive Plan and the Huntsman Corporation Stock Incentive Plan, as amended and restated (together, the “Prior Plans”), remain in effect for outstanding awards granted pursuant to the Prior Plans, butno further awards* maybe granted under the Prior Plans. Under the2025* Stock Incentive Plan we* maygrant nonstatutory stock options, incentive stock options, stock appreciation rights, restricted stock, restricted stock units, stock awards, dividend equivalents, cash 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 maybe granted solely to employees. The terms of the grants under the2025* Stock Incentive Plan and the Prior Plans are fixed at the grant date. As of* September 30, 2025,we had approximately 4.6 million shares remaining under the2025* Stock Incentive Plan available for grant. 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. Outstanding stock-based awards generally vest over athree-year period.

The compensation cost from continuing operations under the stock-based compensation plans for our Company and Huntsman International were as follows (dollars in millions):

The total income tax benefit recognized in the condensed consolidated statements of operations for us and Huntsman International for stock-based compensation arrangements was approximatelynil and $1 million for thenine months ended* September 30, 2025and2024*, respectively.

​

Stock Options

​

The fair value of each stock option award was estimated on the date of grant using the Black-Scholes valuation model. Expected volatilities were 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.

During each of thenine months ended* September 30, 2025and2024*, no stock options were granted.

A summary of stock option activity under the stock-based compensation plans as of* September 30, 2025* and changes during thenine months then ended is presented below:

As of* September 30, 2025*, there wasno unrecognized compensation cost related to nonvested stock option arrangements granted under the stock-based compensation plans.

The total intrinsic value of stock options exercised during thenine months ended* September 30, 2025and2024* was approximatelynil and $1 million, respectively. Cash received from stock options exercised during both of thenine months ended* September 30, 2025and2024* was approximatelynil. The cash tax benefit from stock options exercised during both of thenine months ended* September 30, 2025and2024* was approximatelynil.

Nonvested Shares

​

Nonvested shares granted under the stock-based compensation plans consist of restricted stock and performance share unit awards, which are accounted for as equity awards, and phantom stock, which is accounted for as a liability award because it can be settled in either stock or cash. The fair value of each restricted stock and phantom stock award is estimated to be the closing stock price of Huntsman’s stock on the date of grant.

​

For our performance share unit awards, the performance criteria are total stockholder return of our common stock relative to the total stockholder return of a specified industry peer group for thethree-year performance periods. The fair value of each performance share unit award is estimated using a Monte Carlo simulation model that uses various assumptions, including an expected volatility rate and a risk-free interest rate. For thenine months ended* September 30, 2025and2024*, the weighted-average expected volatility rate was 30.0% and 31.8%, respectively, and the weighted average risk-free interest rate was 4.30% and 4.39%, respectively. For the performance share unit awards granted during thenine months ended* September 30, 2025and2024*, the number of shares earned varies based upon the Company achieving certain performance criteria over athree-year performance period.

A summary of the status of our nonvested shares as of* September 30, 2025* and changes during thenine months then ended is presented below:

​

As of* September 30, 2025*, there was approximately $36 million of total unrecognized compensation cost related to nonvested share compensation arrangements granted under the stock-based compensation plans. That cost is expected to be recognized over a weighted-average period of approximately 1.8 years. The value of share awards that vested during thenine months ended* September 30, 2025and2024* was approximately $26 million and $24 million, respectively.

19. 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 thannot that they will be realized. Valuation allowances are reviewed on an individual 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. These conclusions require significant judgment. In evaluating the objective evidence that historical results provide, we consider the cyclicality of our 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.

We recorded income tax expense from continuing operations of $25 million and $32 million for thenine months ended* September 30, 2025and2024*, respectively. Huntsman International recorded income tax expense from continuing operations of $26 million and $32 million for thenine months ended* September 30, 2025and2024*, respectively. We are required to calculate our interim income tax provision using the estimated annual effective tax rate (“AETR”) method prescribed by Accounting Standards Codification740-270. However, due to current economic conditions resulting in low marginal pre-tax income, negative global AETR and significant losses in jurisdictions with full valuation allowances, starting with thesecond quarter of2025 we expanded our AETR method to exclude loss jurisdictions for whichno benefit can be recognized in that jurisdiction (as opposed tono benefit can be realized in any jurisdiction) from the overall computation of the estimated AETR and a separate estimated AETR is computed and applied to these loss jurisdictions. We believe that this method provides a more reliable forecast of the AETR.

During thesecond quarter of2025, we recorded a discrete release of valuation allowances of approximately $8 million following the announced closure of our Moers, Germany facility. As a result of our Moers facility closure, there is sufficient positive evidence that the Germany tax filing group (without our Moers facility) is more likely thannot to realize the group deferred tax assets. The losses from our Moers facility closure willnot be available to the continuing German tax filing group and we continue to have a full valuation allowance against these net deferred tax assets. During thefirst half of2025, we also recorded discrete establishments of valuation allowances of approximately $13 million. During thefirst quarter of2025, we recorded a discrete tax expense of $8 million resulting from income associated with the Praxair litigation. During thefirst quarter of2024, we recorded a discrete tax benefit of $18 million resulting from the write-off of certain prepaid assets related to operating agreements with SLIC and other joint venture partners concurrent with the separation and acquisition of assets of SLIC. Our tax expense is significantly 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 particular, we recognize tax expense in jurisdictions with pre-tax income but donot recognize a tax benefit from pre-tax losses in jurisdictions with valuation allowances.

On* July 4, 2025,the U.S. enacted tax reform legislation through the One Big Beautiful Bill Act (“OBBBA”). Included in this legislation are provisions that allow for the immediate expensing of domestic U.S. research and development expenses, immediate expensing of certain capital expenditures, changes to the interest expense limitation and other changes to the U.S. taxation of profits derived from foreign operations. OBBBA didnot* have a material impact on our condensed consolidated financial statements.** **

20. EARNINGS PER SHARE

​

Basic income per share excludes dilution and is computed by dividing net income attributable to Huntsman Corporation 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 attributable to Huntsman Corporation by the weighted average number of shares outstanding during the period increased by the number of additional shares that would have been outstanding as potential dilutive securities. Diluted income per share is computed using the treasury stock method for all stock-based awards. In periods with reported loss from continuing operations attributable to Huntsman Corporation, all stock-based awards are generally deemed anti-dilutive and would be excluded from the calculation of diluted income per share from continuing operations, discontinued operations and net income regardless of whether there is income or loss from discontinued operations and net income.

​

Basic and diluted loss per share were determined using the following information (in millions):

Additional stock-based awards of approximately 4.8 million and 2.9 million weighted average equivalent shares of stock were outstanding during thethree months ended* September 30, 2025and2024*, respectively, and approximately 4.9 million and 2.7 million weighted average equivalent shares of stock were outstanding during thenine months ended* September 30, 2025and2024*, respectively. However, these stock-based awards werenot included in the computation of diluted income per share for the respective periods mentioned above because the effect would be anti-dilutive. For thethree months ended* September 30, 2025and2024*, there were 0.4 million and 0.6 million, respectively, weighted average equivalent shares of stock included in the total anti-dilutive weighted average equivalent shares of stock noted above as a result of the reported loss from continuing operations attributable to Huntsman Corporation. For thenine months ended* September 30, 2025and2024*, there were 0.4 million and 0.7 million, respectively, weighted average equivalent shares of stock included in the total anti-dilutive weighted average equivalent shares of stock noted above as a result of the reported loss from continuing operations attributable to Huntsman Corporation.

21. OPERATING SEGMENT INFORMATION

​

We derive our revenues, earnings and cash flows from the manufacture and sale of a wide variety of diversified organic chemical products. We have three operating segments, which are also our reportable operating segments: Polyurethanes, Performance Products and Advanced Materials. We have organized our business and derived our operating segments around differences in product lines.

The major products of each reportable operating segment are as follows:

​

Sales between segments are generally recognized at external market prices and are eliminated in consolidation. We use adjusted EBITDA to measure the financial performance of our global business units and for reporting the results of our operating segments. This measure includes all operating items relating to the businesses. The adjusted EBITDA of operating segments excludes items that principally apply to our Company as a whole. The following schedule includes revenues, significant segment expenses and adjusted EBITDA for each of our reportable operating segments (dollars in millions).
