THE WOODLANDS, Texas – Huntsman Corporation (NYSE: HUN) today reported third quarter 2019 results with revenues of $1,687 million, net income of $41 million, adjusted net income of $95 million and adjusted EBITDA of $215 million.

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

“In spite of an increasingly challenging global economic environment, I have never been more pleased about our mix of businesses and the strength of our balance sheet. We continue our strategy to move and shift our asset portfolio to more downstream, stable and resilient businesses, as well as to manage effectively our working capital and balance sheet. We are on track to close the divestiture of our Chemical Intermediates and Surfactants businesses in early 2020, yielding approximately $1.6 billion of net proceeds upon completion. This, coupled with our ongoing strong free cash flow and investment grade balance sheet will provide us with abundant resource and flexibility in our ongoing balanced approach to capital allocation which includes organic and inorganic expansion, opportunistic share repurchases and a competitive dividend. We are very well positioned for the future.”

Segment Analysis for 3Q19 Compared to 3Q18

Polyurethanes

The decrease in revenues in our Polyurethanes segment for the three months ended September 30, 2019 compared to the same period of 2018 was due to lower MDI average selling prices, partially offset by higher MDI sales volumes. MDI average selling prices decreased primarily due to a decline in component MDI selling prices in China and Europe. MDI sales volumes increased primarily due to the start-up of our new Chinese MDI facility in the third quarter of 2018. The decrease in segment adjusted EBITDA was primarily due to lower MDI margins driven by lower MDI pricing, partially offset by higher MDI sales volumes.

Performance Products

The decrease in revenues in our Performance Products segment for the three months ended September 30, 2019 compared to the same period of 2018 was due to lower average selling prices and lower sales volumes. Average selling prices decreased primarily due to lower raw material costs and weakened market conditions. Sales volumes decreased primarily due to weakened market conditions. The decrease in segment adjusted EBITDA was primarily due to lower sales volumes and lower margins, primarily in our ethyleneamines business, partially offset by higher margins in our specialty amines business.

Advanced Materials

The decrease in revenues in our Advanced Materials segment for the three months ended September 30, 2019 compared to the same period in 2018 was due to lower sales volumes and lower average selling prices. Sales volumes decreased across most markets primarily due to economic slowdown and customer destocking, particularly in our European region. Average selling prices decreased primarily due to the impact of a stronger U.S. dollar against major international currencies, partially offset by higher local currency selling prices. Segment adjusted EBITDA decreased due to lower sales volumes.

Textile Effects

The decrease in revenues in our Textile Effects segment for the three months ended September 30, 2019 compared to the same period of 2018 was due to lower sales volumes and lower average selling prices. Sales volumes decreased primarily due to lower demand primarily resulting from market uncertainties surrounding U.S. and China trade. Average selling prices decreased as a result of competitive market pressures and the impact of a stronger U.S. dollar against major international currencies. The decrease in segment adjusted EBITDA was primarily due to lower sales volumes and higher raw material costs, partially offset by lower fixed costs.

Corporate, LIFO and other

For the three months ended September 30, 2019, adjusted EBITDA from Corporate and other for Huntsman Corporation increased by $9 million to a loss of $36 million from a loss of $45 million for the same period of 2018.

During the three months ended September 30, 2019, our free cash flow from continuing operations was $197 million compared to $191 million in the prior year period. As of September 30, 2019, we had $1,707 million of combined cash and unused borrowing capacity.

During the three months ended September 30, 2019, we spent $63 million on capital expenditures compared to $59 million in the same period of 2018. In 2019, we expect to spend approximately $270 million on capital expenditures for continuing operations and approximately $70 million for the Chemical Intermediates and Surfactants businesses reported as discontinued operations.

During the three months ended September 30, 2019, we spent approximately $81 million to repurchase approximately 4.1 million shares. As of the end of the third quarter 2019, we have approximately $528 million remaining on our existing $1 billion multiyear share repurchase program.

Income Taxes

During the three months ended September 30, 2019, we recorded income tax expense of $30 million compared to $16 million during the same period in 2018.

(a)	During the nine months ended September 30, 2018, we released $119 million of valuation allowances in Switzerland, the U.K., and Luxembourg. We eliminated the effect of this significant change in tax valuation allowances from our presentation of adjusted net income to allow investors to better compare our ongoing financial performance from period to period.
	We do not adjust for insignificant changes in tax valuation allowances because we do not believe this provides more meaningful information than is provided under GAAP.
(b)	Represents the changes in market value in Huntsman's remaining interesting in Venator.

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 (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, 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 costs (credits); and further adjusted for certain other items set forth in reconciliation of adjusted EBITDA to net income (loss) 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 costs (credits); and further adjusted for certain other items set forth in reconciliation of adjusted EBITDA to 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 do not provide reconciliations for adjusted EBITDA, adjusted net income (loss) or adjusted diluted income (loss) per share on a forward-looking basis because we are 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 and purchase accounting adjustments, (b) merger costs, and (c) certain legal and other settlements and related costs. Each of such adjustments has not yet occurred, are out of our control and/or cannot be reasonably predicted. For the same reasons, we are unable to address the probable significance of the unavailable information.

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.

(3)

During the third quarter 2019, we entered into an agreement to sell our Chemical Intermediates and Surfactants businesses, which are now reported as held for sale. In 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.

(4)

We believe 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. We do not provide reconciliations for adjusted effective tax rate on a forward-looking basis because we are 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 our control and/or cannot be reasonably predicted. For the same reasons, we are unable to address the probable significance of the unavailable information.

(5) 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.
