Select HistoricalFinancials Updated to reflect treatment of Pigments & Additives as discontinued operations

General As previously announced, we completed the separation of our Pigments & Additives division through an Initial Public Offering (“IPO”) of ordinary shares of Venator Materials PLC (“Venator”) on August 8, 2017. It is our intention to monetize our 75.4% retained ownership in Venator at prevailing market conditions and expect to implement multiple follow-on capital market or block transactions that permit an orderly distribution of Huntsman's retained shares. This presentation reclassifies select historical financial data, reflecting the results of the associated Pigments & Additives business as discontinued operations. This presentation contains financial measures that are not in accordance with generally accepted accounting principles in the U.S. ("GAAP"), including EBITDA, adjusted EBITDA, adjusted EBITDA from discontinued operations, normalized EBITDA, adjusted net income (loss), adjusted diluted income (loss) per share, free cash flow and net debt. The Company has provided reconciliations of non-GAAP financial measures to the most directly comparable GAAP financial measures in the Appendix to this presentation. Forward-Looking Statements: This presentation includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. 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, business trends and other information that is not historical information.

The forward-looking statements in this release are subject to uncertainty and changes in circumstances and involve risks and uncertainties that may affect the company's operations, markets, products, services, prices and other factors as discussed in the Huntsman companies' filings with the U.S. Securities and Exchange Commission.

Explanatory Notes 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 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. 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, net of tax; (b) interest; (c) income taxes; (d) depreciation and amortization; (e) acquisition and integration expenses; (f) EBITDA from discontinued operations; (g) minority interest from discontinued operations; (h) loss (gain) on disposition of businesses/assets; (i) loss on early extinguishment of debt; (j) expenses associated with merger, net of tax; (k) certain legal settlements and related expenses; (l) amortization of pension and postretirement actuarial losses (gains) and; (m) restructuring, impairment and plant closing and transition costs (credits). The reconciliation of adjusted EBITDA to net income (loss) is set forth in these tables. 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) acquisition and integration expenses; (c) loss (income) from discontinued operations; (d) minority interest from discontinued operations; (e) loss (gain) on disposition of businesses/assets; (f) loss on early extinguishment of debt; (g) expenses associated with merger, net of tax; (h) certain legal settlements and related expenses; (i) amortization of pension and postretirement actuarial losses (gains); and (j) restructuring, impairment and plant closing and transition costs (credits). 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 do not adjust for changes in tax valuation allowances because we do not believe it provides more meaningful information than is provided under GAAP. The reconciliation of adjusted net income (loss) to net income (loss) is set forth in these tables. Pro forma adjusted to exclude the sale of our European differentiated surfactants business to Innospec Inc. on December 30, 2016 as if it had occurred at the beginning of the relevant period. Management internally uses a free cash flow measure: (a) to evaluate the Company's liquidity, (b) to evaluate strategic investments, (c) to plan stock buyback and dividend levels and (d) to evaluate the Company's ability to incur and service debt. 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. The Company defines free cash flow as cash flow provided by operating activities less cash flow used in investing activities, excluding acquisition/disposition activities and non-recurring separation costs. Free cash flow is typically derived directly from the Company's condensed consolidated statement of cash flows; however, it may be adjusted for items that affect comparability between periods. During the third quarter of 2017 we separated our Pigments and Additives division through an Initial Public Offering of Venator Materials PLC; Additionally, during the first quarter 2010 we closed our Australian styrenics operations. Results from these associated businesses are treated as discontinued operations. 1) 2) 3) 4) 20
