THE WOODLANDS, Texas — Huntsman Corporation (NYSE: HUN) today reported first quarter 2019 results with revenues of $2,034 million, net income of $131 million, adjusted net income of $108 million and adjusted EBITDA of $257 million.

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

“While global economic conditions remained challenging in the first quarter of this year, we are pleased with the relative resilience of our core downstream portfolio. The month of March ended slightly better than we projected, and while we remain cautious of certain regions of the world, notably Europe, we see momentum returning to Asia, especially in China. In 2019, we are on course to achieve our second best year ever. We remain focused on delivering consistent strong free cash flow and executing our downstream strategy through strategic investments, new products and continued globalization of recent bolt-on acquisitions. Our balance sheet is strong, our dividend yield is attractive, and we continue our balanced approach to capital allocation, including share repurchases.”

Segment Analysis for 1Q19 Compared to 1Q18

Polyurethanes

The decrease in revenues in our Polyurethanes segment for the three months ended March 31, 2019, compared to the same period of 2018 was due to lower average MDI and MTBE selling prices, partially offset by higher MDI sales volumes. MDI average selling prices decreased primarily due to a decline in polymeric MDI selling prices in China and Europe. MTBE average selling prices decreased primarily as a result of lower pricing for high octane gasoline. MDI sales volumes increased primarily due to the start-up of our new Chinese MDI facility in 2018 and the acquisition of Demilec in the second quarter of 2018. The decrease in adjusted EBITDA was primarily due to lower MDI margins driven by lower MDI pricing and lower MTBE margins, partially offset by higher sales volumes.

Performance Products

The decrease in revenues in our Performance Products segment for the three months ended March 31, 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 weakened market conditions. Average selling prices decreased primarily due to lower raw material costs and weakened market conditions. The decrease in segment adjusted EBITDA was primarily due to lower sales volumes and lower average selling prices, primarily in our upstream intermediates businesses.

Advanced Materials

The decrease in revenues in our Advanced Materials segment for the three months ended March 31,2019, compared to the same period in 2018 was primarily due to lower average selling prices. 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. The impact of sales volumes on revenues remained relatively flat as favorable product mix effect from sales volumes in our aerospace components market was offset by lower sales volumes in our power and automotive related markets. Segment adjusted EBITDA decreased due to higher fixed costs and higher raw material costs.

Textile Effects

The decrease in revenues in our Textile Effects segment for the three months ended March 31, 2019 compared to the same period of 2018 was due to lower sales volumes, partially offset by higher average selling prices. Sales volumes decreased primarily due to lower demand resulting from market uncertainties surrounding U.S. and China trade, as well as from textile mill closures in China due to regulatory measures. Average selling prices increased in response to higher raw material costs, partially offset by 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 materials costs, partially offset by higher average selling prices.

Corporate, LIFO and other

For the three months ended March 31, 2019, segment adjusted EBITDA from Corporate and other for Huntsman Corporation improved $5 million to a loss of $38 million from a loss of $43 million in the same period in 2018, primarily due to benefit in LIFO inventory reserves, partially offset by foreign currency losses.

Liquidity, Capital Resources and Outstanding Debt

During the three months ended March 31, 2019, our free cash flow was a use of $101 million compared to a source of $56 million in the prior year period. This decrease is primarily due to lower earnings in the three months ended March 31, 2019, and net working capital metrics were temporarily higher than targeted levels. However, we reconfirm our full year 2019 targeted free cash flow conversion of near 40%. As of March 31, 2019, we had $1,445 million of combined cash and unused borrowing capacity.

During the three months ended March 31, 2019, we spent $70 million on capital expenditures compared to $55 million in the same period of 2019. In 2019, we expect to spend approximately $380 million on capital expenditures.

Through the end of the first quarter 2019, we have spent approximately $34 million to repurchase approximately 1.5 million shares. As of the end of the first quarter 2019, we have approximately $690 million remaining on our existing $1 billion multiyear share repurchase program.

Income Taxes

During the three months ended March 31, 2019, we recorded income tax expense of $52 million compared to $53 million during the same period in 2018. In the first quarter 2019, our adjusted effective tax rate was 19%. We expect our forward adjusted effective tax rate will be approximately 21% - 23%.

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 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.

(2) 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 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.
