Huntsman Announces Second Quarter 2023 Earnings

Second Quarter Highlights

THE WOODLANDS, Texas – Huntsman Corporation (NYSE: HUN) today reported second quarter 2023 results with revenues of $1,596 million, net income attributable to Huntsman of $19 million, adjusted net income attributable to Huntsman of $39 million and adjusted EBITDA of $156 million.

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

“During the quarter, business activity in each of our core regions remained under pressure, although we did see demand fundamentals in many of our core markets stabilize, albeit at a lower level than the prior year. We continued to drive efficiencies in our cost structure which will ensure we are well positioned to improve profitability once demand returns to a more normalized level. We remain positive on the long-term trends and value we will capture in energy efficiency and lightweighting in the construction, transportation, and industrial markets. Over the past several years we have made a significant effort to reduce leverage and drive capital discipline. The output of this effort is now allowing us to return significant amounts of capital to shareholders during a year which for the chemical industry may end up being just as, if not more, challenging than the pandemic year 2020. Our financial strength is also allowing us to evaluate both organic and in-organic investment opportunities to strengthen our Company for the long-term, however, we will continue to be disciplined with our available capital and protect our investment grade rating.”

Segment Analysis for 2Q23 Compared to 2Q22

Polyurethanes

The decrease in revenues in our Polyurethanes segment for the three months ended June 30, 2023 compared to the same period of 2022 was primarily due to lower sales volumes, lower MDI average selling prices and the negative impact of foreign currency exchange rate movements against the U.S dollar. Sales volumes decreased primarily due to lower demand, primarily in the Americas. MDI average selling prices decreased primarily due to less favorable supply and demand dynamics. The decrease in segment adjusted EBITDA was primarily due to lower sales volumes, lower MDI margins, the negative impact of foreign currency exchange rate movements against the U.S. dollar and a gain from an insurance settlement received in the second quarter of 2022, partially offset by higher equity earnings from our minority-owned joint venture in China and cost savings achieved from our cost optimization programs.

Performance Products

The decrease in revenues in our Performance Products segment for the three months ended June 30, 2023 compared to the same period of 2022 was primarily due to lower sales volumes and reduced average selling prices, partially offset by improved sales mix. Sales volumes decreased in all regions primarily due to slowing construction activity, and reduced demand in coatings and adhesives, lubes and other industrial markets. The decrease in segment adjusted EBITDA was primarily due to decreased sales volumes and lower average selling prices.

Advanced Materials

The decrease in revenues in our Advanced Materials segment for the three months ended June 30, 2023 compared to the same period of 2022 was primarily due to lower sales volumes, partially offset by higher average selling prices. Sales volumes decreased primarily due to reduced customer demand in our infrastructure markets and the deselection of lower margin business. Average selling prices increased largely due to improved sales mix. The decrease in segment adjusted EBITDA was primarily due to lower sales volumes.

Corporate, LIFO and other

For the three months ended June 30, 2023, adjusted EBITDA from Corporate and other was a loss of $38 million, which remained the same as a loss of $38 million for the same period of 2022.

Liquidity and Capital Resources

During the three months ended June 30, 2023, our free cash flow from continuing operations was a use of cash of $11 million as compared to a source of cash of $178 million in the same period of 2022. As of June 30, 2023, we had approximately $1.9 billion of combined cash and unused borrowing capacity.

During the three months ended June 30, 2023, we spent $51 million on capital expenditures from continuing operations as compared to $65 million in the same period of 2022. During 2023, we expect to spend between $230 million to $250 million on capital expenditures.

Income Taxes

In the second quarter of 2023, our effective tax rate was 46% and our adjusted effective tax rate was 39%. We expect our 2023 adjusted effective tax rate to be approximately 26% to 29%. We expect our long-term adjusted effective tax rate to be approximately 22% to 24%. Our second quarter 2023 tax expense was negatively impacted by an $8 million non-cash valuation allowance increase.

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, net of tax; (b) interest; (c) income taxes; (d) depreciation and amortization; (e) amortization of pension and postretirement actuarial losses (gains); (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 interest; (b) amortization of pension and postretirement actuarial losses (gains); (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.
