Huntsman Announces Third Quarter 2025 Earnings

Third Quarter Highlights

See end of press release for footnote explanations and reconciliations of non-GAAP measures.

THE WOODLANDS, Texas – Huntsman Corporation (NYSE: HUN) today reported third quarter 2025 results with revenues of $1,460 million, net loss attributable to Huntsman of $25 million, adjusted net loss attributable to Huntsman of $5 million and adjusted EBITDA of $94 million.

Peter R. Huntsman, Chairman, President, and CEO, commented:

“As we expected, third quarter fundamentals remained consistent with the first half of the year. Volumes improved compared to the prior year while pricing in some parts of the portfolio remained under pressure. Cash generation and cost control remain top priorities for our Company. Our current restructuring programs, that will likely exceed $100 million in savings, remain on track and are expected to be completed in 2026. Additionally, our cash generation over the past year has been strong despite lower levels of profitability, reflecting quick actions taken on working capital and capital expenditure control in an ever-challenging environment. After thorough deliberation, and reflecting the global economic conditions of our industry, our Board decided to reset the regular dividend to 35 cents a share annually, a reduction of 65%. The adjusted dividend payout will allow us to preserve our financial flexibility as we continue to navigate this extended cyclical trough, while also allowing the Company to keep a balanced capital allocation program including a competitive regular dividend. We would anticipate returning to a higher dividend payout as soon as conditions warrant."

Segment Analysis for 3Q25 Compared to 3Q24

Polyurethanes

The decrease in revenues in our Polyurethanes segment for the three months ended September 30, 2025 compared to the same period of 2024 was primarily due to lower average selling prices, partially offset by higher sales volumes. MDI average selling prices decreased primarily due to less favorable supply and demand dynamics. Sales volumes increased primarily in the Americas and Asia regions. The decrease in segment adjusted EBITDA was primarily due to the impacts of lower average selling prices, inventory reductions and lower equity earnings from our minority-owned joint venture in China, partially offset by higher sales volumes, lower raw material costs and cost savings achieved from our cost optimization program.

Performance Products

The decrease in revenues in our Performance Products segment for the three months ended September 30, 2025 compared to the same period of 2024 was primarily due to lower sales volumes and lower average selling prices. Sales volumes decreased primarily due to the closure of our Moers, Germany maleic anhydride facility and overall softening market conditions. Average selling prices decreased primarily due to competitive pressures. The decrease in segment adjusted EBITDA was primarily due to lower sales volumes and margins.

Advanced Materials

The increase in revenues in our Advanced Materials segment for the three months ended September 30, 2025 compared to the same period of 2024 was primarily due to higher average selling prices. Average selling prices increased primarily due to the positive impact of major foreign currency exchange rate movements against the U.S. dollar. Sales volumes were essentially unchanged from the same period in 2024. Segment adjusted EBITDA was slightly lower primarily due to an unfavorable impact from inventory reductions.

Liquidity and Capital Resources

During the three months ended September 30, 2025, our free cash flow from continuing operations was $157 million as compared to $93 million in the same period of 2024. As of September 30, 2025, we had approximately $1.4 billion of combined cash and unused borrowing capacity.

During the three months ended September 30, 2025, we spent $43 million on capital expenditures from continuing operations as compared to $41 million in the same period of 2024. During 2025, we expect to spend between approximately $170 million to $180 million on capital expenditures.

Income Taxes

In the third quarter of 2025, our effective tax rate was -43% and our adjusted effective tax rate was 40%.

Footnotes

Adjusted EBITDA, adjusted net income (loss) and adjusted diluted income (loss) per share, as used herein, are not necessarily comparable to other similarly titled measures of other companies.

Adjusted EBITDA is computed by eliminating the following from net income (loss): (a) net income attributable to noncontrolling interests; (b) interest expense, net; (c) income taxes; (d) depreciation and amortization; (e) amortization of pension and postretirement actuarial losses; (f) restructuring, impairment and plant closing and transition costs; and further adjusted for certain other items set forth in the reconciliation of net income (loss) to adjusted EBITDA in Table 4 above.

Adjusted net income (loss) and adjusted diluted income (loss) per share are computed by eliminating the after tax impact of the following items from net income (loss): (a) net income attributable to noncontrolling interests; (b) amortization of pension and postretirement actuarial losses; (c) restructuring, impairment and plant closing and transition costs; and further adjusted for certain other items set forth in the reconciliation of net income (loss) to adjusted net income (loss) in Table 4 above. The income tax impacts, if any, of each adjusting item represent a ratable allocation of the total difference between the unadjusted tax expense and the total adjusted tax expense, computed without consideration of any adjusting items using a with and without approach.

We may disclose forward-looking adjusted EBITDA because we cannot adequately forecast certain items and events that may or may not impact us in the near future, such as business acquisition and integration expenses and purchase accounting inventory adjustments, net, certain legal and other settlements and related expenses, gains on sale of businesses/assets and certain tax only items, including tax law changes not yet enacted. Each of such adjustment has not yet occurred, is out of our control and/or cannot be reasonably predicted. In our view, our forward-looking adjusted EBITDA represents the forecast net income on our underlying business operations but does not reflect any adjustments related to the items noted above that may occur and can cause our adjusted EBITDA to differ.
