These forward-looking statements include statements concerning our plans, objectives, goals, strategies, future events, future revenue or performance, capital expenditures, financing needs, plans or intentions relating to acquisitions, divestitures or strategic transactions, including the planned merger of equals with Olin Corporation, statements about the anticipated benefits of the contemplated transaction, including future expected synergies and cost savings related to the contemplated transaction, the plans, objectives, expectations and intentions of Olin, Huntsman or the combined company business trends and any other information that is not historical information. When used in this presentation, the words “estimates,” “expects,” “anticipates,” “likely,” “projects,” “outlook,” “plans,” “intends,” “believes,” “forecasts,” or future or conditional verbs, such as “will,” “should,” “could” or “may,” and variations of such words or similar expressions are intended to identify forward-looking statements. These forward-looking statements, including, without limitation, management’s examination of historical operating trends and data, are based upon our current expectations and various assumptions and beliefs. In particular, such forward-looking statements are subject to uncertainty and changes in circumstances and involve risks and uncertainties that may affect the company's operations, markets, products, prices and other factors as discussed in the Company’s filings with the Securities and Exchange Commission (the “SEC”). Significant risks and uncertainties may relate to, but are not limited to, uncertainties as to the timing of the contemplated merger; the possibility that the closing conditions to the contemplated merger may not be satisfied or waived, including that a governmental entity may prohibit, delay or refuse to grant a necessary regulatory approval; the effects of disruption caused by the contemplated merger making it more difficult to maintain relationships with employees, customers, vendors and other business partners; the risk that stockholder litigation in connection with the contemplated merger may affect the timing or occurrence of the contemplated merger or result in significant costs of defense, indemnification and liability; ability to refinance existing indebtedness of Huntsman in connection with the contemplated merger; other business effects, including the effects of industry, economic or political conditions outside of the control of the parties to the contemplated merger; transaction costs; high energy costs in Europe, inflation and high capital costs, geopolitical instability, volatile global economic conditions, cyclical and volatile product markets, disruptions in production at manufacturing facilities, reorganization or restructuring of the Company’s operations, including any delay of, or other negative developments affecting the ability to implement cost reductions and manufacturing optimization improvements in the Company’s businesses and to realize anticipated cost savings, and other financial, operational, economic, competitive, environmental, political, legal, regulatory and technological factors. Any forward- looking statement should be considered in light of the risks set forth under the caption “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2025, which may be supplemented by other risks and uncertainties disclosed in any subsequent reports filed or furnished by the Company from time to time. All forward-looking statements apply only as of the date made. Except as required by law, the Company undertakes no obligation to update or revise forward-looking statements to reflect events or circumstances that arise after the date made or to reflect the occurrence of unanticipated events. Non-GAAP Financial Measures This presentation contains financial measures that are not in accordance with generally accepted accounting principles in the U.S. ("GAAP"), including adjusted EBITDA, adjusted EBITDA from discontinued operations, adjusted net income (loss), adjusted diluted income (loss) per share, free cash flow, adjusted effective tax rate, and net debt. For more information on the non-GAAP financial measures used by the Company and referenced in this presentation, including definitions and reconciliations of non-GAAP measures to GAAP, please refer to “Non-GAAP Reconciliation” hyperlink available in the “Financials” section of the Company’s website at www.huntsman.com/investors. The Company does not provide reconciliations of forward-looking non-GAAP financial measures to the most comparable GAAP financial measures on a forward-looking basis because the Company is unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the timing and amount of certain items, such as, but not limited to, (a) business acquisition and integration expenses, (b) merger costs, and (c) certain legal and other settlements and related costs. Each of such adjustments has not yet occurred, are out of the Company's control and/or cannot be reasonably predicted. For the same reasons, the Company is unable to address the probable significance of the unavailable information.
