THE WOODLANDS, Texas –

Huntsman Corporation (NYSE: HUN) today reported second quarter 2026 results with revenues of $1,663 million, net loss attributable to

Huntsman of $6 million, adjusted net income attributable to Huntsman of nil and adjusted EBITDA of $120 million.

Peter R. Huntsman,

Chairman, President, and CEO, commented:

“We delivered a solid quarter,

supported by higher volumes across all three segments and pricing actions that offset a significant increase in raw material costs. Improved

industrial demand helped counter continued softness in construction. Rising and volatile energy and crude oil related costs, particularly

in Europe, remain a headwind, and we will stay focused on additional price increases and cost-reduction initiatives to help offset these

pressures.

Our planned merger of equals with

Olin Corporation continues to progress at pace. The strong collaboration between our teams reinforces my confidence in our ability to

deliver the synergy targets we have outlined. We also expect the combined company to benefit from vertical integration, greater scale,

and a stronger financial profile, creating meaningful value for shareholders of both companies. The stockholder vote is scheduled for

August 25, 2026, and we are excited about the future of OlinHuntsman.”

Segment Analysis for 2Q26 Compared

to 2Q25

Polyurethanes

The increase in revenues in our Polyurethanes

segment for the three months ended June 30, 2026 compared to the same period of 2025 was primarily due to higher average selling

prices and higher sales volumes. MDI average selling prices increased across all three regions due to improved supply and demand dynamics.

MDI sales volumes increased in the Americas and Europe regions. The increase in segment adjusted EBITDA was primarily due to higher average

selling prices, higher sales volumes, higher equity earnings from our minority-owned joint venture in China and cost savings achieved

from our cost optimization program, partially offset by higher raw materials costs.

Performance Products

The increase in revenues in our Performance

Products segment for the three months ended June 30, 2026 compared to the same period of 2025 was primarily due to higher sales

volumes and slightly higher average selling prices. Sales volumes increased primarily due to favorable demand in our performance amines

business. Average selling prices increased primarily due to higher raw materials costs. The increase in segment adjusted EBITDA was primarily

due to higher sales volumes and lower fixed costs achieved from our cost optimization program.

Advanced Materials

The increase in revenues in our Advanced

Materials segment for the three months ended June 30, 2026 compared to the same period of 2025 was primarily due to higher average

selling prices and higher sales volumes. Average selling prices increased primarily due to favorable sales mix and the positive impact

of major foreign currency exchange rate movements against the U.S. dollar. Sales volumes increased primarily in our aerospace, power

and automotive markets. The increase in segment adjusted EBITDA was primarily due to higher margins and higher sales volumes.

Liquidity and Capital Resources

During the three months ended June 30,

2026, our free cash flow used was $90 million as compared to a source of cash of $55 million in the same period of 2025. As of June 30,

2026, we had approximately $0.9 billion of combined cash and unused borrowing capacity.

- 2 -

During the three months ended June 30,

2026, we spent $30 million on capital expenditures as compared to $37 million in the same period of 2025. During 2026, we expect capital

expenditures to be approximately $170 million.

Income Taxes

In the second quarter of 2026, our effective

tax rate was 65% and our adjusted effective tax rate was 61%.

Footnotes

(1) We use adjusted EBITDA to measure the operating performance of our business and for planning and evaluating the performance of our

business segments. We provide adjusted net income (loss) because we feel it provides meaningful insight for the investment community into

the performance of our business. We believe that net income (loss) is the performance measure calculated and presented in accordance with

generally accepted accounting principles in the U.S. (“GAAP”) that is most directly comparable to adjusted EBITDA and adjusted

net income (loss). Additional information with respect to our use of each of these financial measures follows:

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.

(2) We believe free cash flow is an important indicator of our liquidity as it measures the amount of cash we generate. Management internally

uses free cash flow measure to: (a) evaluate our liquidity, (b) evaluate strategic investments, (c) plan stock buyback

and dividend levels and (d) evaluate our ability to incur and service debt. Free cash flow is defined as net cash provided by (used

in) operating activities less capital expenditures. Free cash flow is not a defined term under U.S. GAAP, and it should not be inferred

that the entire free cash flow amount is available for discretionary expenditures.

(3) We believe the adjusted effective tax rate provides improved

comparability between periods through the exclusion of certain items that management believes are not indicative of the businesses’

operational profitability and that may obscure underlying business results and trends. In our view, effective tax rate is the performance

measure calculated and presented in accordance with U.S. GAAP that is most directly comparable to adjusted effective tax rate. The reconciliation

of historical adjusted effective tax rate and effective tax rate is set forth in Table 4 above. Please see the reconciliation of our

net income to adjusted net income in Table 4 for details regarding the tax impacts of our non-GAAP adjustments.

(4) Net debt is a measure we use to monitor how much debt we have

after taking into account our total cash. We use it as an indicator of our overall financial position, and calculate it by taking our

total debt, including the current portion, and subtracting total cash.

(5) Certain prior period amounts have been reclassified in the condensed

consolidated financial statements to conform to current period presentation.
