First 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 first quarter 2024 results with revenues of $1,470 million, net loss attributable to Huntsman of $37 million, adjusted net loss attributable to Huntsman of $11 million and adjusted EBITDA of $81 million.

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

“As we expected, the first quarter of 2024 improved sequentially versus the fourth quarter due largely to higher sales volumes and improved margins. We expect these trends to continue into a seasonally stronger second quarter. While overall demand for our products, as well as our margins in Polyurethanes remain below historical averages, we remain confident that we will see both elements improve as our key markets recover over the next several quarters. We are focused on controlling our costs to drive higher returns and cash flow to provide flexibility to invest in the Company for the long-term and return cash to shareholders.”

Segment Analysis for 1Q24 Compared to 1Q23

Polyurethanes

The decrease in revenues in our Polyurethanes segment for the three months ended March 31, 2024 compared to the same period of 2023 was primarily due to lower MDI average selling prices and unfavorable mix, partially offset by higher sales volumes. MDI average selling prices decreased primarily due to less favorable supply and demand dynamics. Sales volumes increased due to modestly improved demand and share gains in certain markets, primarily in the Americas and Europe regions. The decrease in segment adjusted EBITDA was primarily due to lower MDI average selling prices, partially offset by lower raw materials costs, higher sales volumes, higher equity earnings and cost savings from our cost optimization programs.

Performance Products

The decrease in revenues in our Performance Products segment for the three months ended March 31, 2024 compared to the same period of 2023 was primarily due to lower average selling prices and unfavorable mix, partially offset by higher sales volumes. Average selling prices decreased primarily due to competitive pressure, particularly in Europe. Sales volumes increased primarily due to improvement in industrial and construction activity as well as increased demand in coatings and adhesives and lubes markets. The decrease in segment adjusted EBITDA was primarily due to lower average selling prices, partially offset by higher sales volumes and lower raw materials costs.

Advanced Materials

The decrease in revenues in our Advanced Materials segment for the three months ended March 31, 2024 compared to the same period of 2023 was primarily due to lower average selling prices and lower sales volumes. Average selling prices decreased primarily in response to lower raw materials costs. The decrease in sales volumes was due to our general industry and commodity markets, partially offset by an increase in our aerospace and electrical infrastructure markets in response to customer demand. The decrease in segment adjusted EBITDA was primarily due to lower sales volumes and foreign currency exchange rate fluctuations, partially offset by improved sales mix.

Corporate, LIFO and other

For the three months ended March 31, 2024, adjusted EBITDA from Corporate and other was a loss of $43 million as compared to a loss of $49 million for the same period of 2023. The improvement was due to lower corporate costs, partially offset by a decrease in foreign currency exchange gains and an increase in LIFO valuation losses.

Liquidity and Capital Resources

During the three months ended March 31, 2024, our free cash flow from continuing operations was a use of cash of $105 million as compared to a use of cash of $168 million in the same period of 2023. As of March 31, 2024, we had approximately $1.6 billion of combined cash and unused borrowing capacity.

During the three months ended March 31, 2024, we spent $42 million on capital expenditures from continuing operations as compared to $46 million in the same period of 2023. During 2024, we expect to spend approximately $200 million on capital expenditures.

Income Taxes

In the first quarter of 2024, our effective tax rate was 56% and our adjusted effective tax rate was 57%. We expect our 2024 adjusted effective tax rate to be approximately 34% to 37%. We expect our long-term adjusted effective tax rate to be approximately 22% to 24%.

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, 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.

Our forward-looking adjusted effective tax rate is calculated based on our forecast effective tax rate, and the range of our forward-looking adjusted effective tax rate equals the range of our forecast effective tax rate.
