THE WOODLANDS, Texas — Huntsman Corporation (NYSE: HUN) today reported third quarter 2018 results with revenues of $2,444 million, net loss of $8 million, adjusted net income of $202 million and adjusted EBITDA of $374 million.

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

“This was a solid quarter overall for our Company, which demonstrated the consistency of our downstream and differentiated businesses. Expected adjustments to short term fundamentals in component MDI provided us an opportunity to show the strength of our unique downstream urethanes portfolio and strategy. In spite of the uncertainty around global trade and certain pockets of softer demand mostly seen in China, long term fundamentals remain intact. We are confident and on track to deliver on our 2020 targets that we laid out at our Investor Day on May 23, 2018. Our free cash flow remains strong with a good performance in the third quarter and our balance sheet continues to strengthen with net leverage improving to 1.3 times, well within investment grade metrics. We are committed to our balanced and opportunistic approach to capital allocation by growing our downstream differentiated portfolio of businesses and repurchasing shares to create long term value for our shareholders.”

Segment Analysis for 3Q18 Compared to 3Q17

Polyurethanes

The increase in revenues in our Polyurethanes segment for the three months ended September 30, 2018 compared to the same period of 2017 was due to higher average selling prices and higher sales volumes. Differentiated MDI average selling prices increased due to strong end-market demand, partially offset by a decline in component MDI prices compared to the prior year period. MTBE average selling prices increased primarily as a result of higher pricing for high octane gasoline. MDI sales volumes increased due to higher demand across most major markets. MTBE sales volumes increased due to the impact of hurricane related production outages during the third quarter of 2017. The modest increase in segment adjusted EBITDA was primarily due to higher MDI volumes and higher MTBE earnings due to hurricane related production outages in the third quarter of 2017, partially offset by lower component MDI margins.

Performance Products

The increase in revenues in our Performance Products segment for the three months ended September 30, 2018 compared to the same period of 2017 was due to higher average selling prices and higher sales volumes. Average selling prices increased primarily due to strong market conditions across several of our derivatives businesses and in response to higher raw material costs. Sales volumes increased primarily due to the impact of hurricane related production outages during the third quarter of 2017. The increase in segment adjusted EBITDA was primarily due to higher average selling prices, higher sales volumes and the impact of hurricane related production outages during the third quarter of 2017.

Advanced Materials

The increase in revenues in our Advanced Materials segment for the three months ended September 30, 2018, compared to the same period in 2017 was due to higher sales volumes and higher average selling prices. Sales volumes increased across most markets in our core specialty business as well as in our commodity business. 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. Segment adjusted EBITDA remained flat primarily due to higher specialty sales volumes, offset by higher raw material and fixed costs.

Textile Effects

The increase in revenues in our Textile Effects segment for the three months ended September 30, 2018 compared to the same period of 2017 was due to higher average selling prices, partially offset by lower sales volumes. 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. Sales volumes decreased primarily due to the impact from supply constraints in China, a de-selection of certain product ranges, and a temporary transition in distribution channels within a few regions. The increase in segment adjusted EBITDA was primarily due to higher average selling prices, partially offset by higher raw material costs, higher selling, general and administrative costs and lower sales volumes.

Corporate, LIFO and other

For the three months ended September 30, 2018, segment adjusted EBITDA from Corporate and other for Huntsman Corporation decreased $4 million to a loss of $47 million from a loss of $43 million in the same period in 2017, primarily due to an increase on LIFO inventory reserves.

Liquidity, Capital Resources and Outstanding Debt

During the quarter we generated free cash flow of $226 million compared to $227 million a year ago. As of September 30, 2018, we had $1,529 million of combined cash and unused borrowing capacity.

During the three months ended September 30, 2018, we spent $71 million on capital expenditures compared to $58 million in the same period of 2017. We expect to spend approximately $300 million to $320 million on capital expenditures in 2018.

Through the end of the third quarter 2018, we have spent approximately $175 million to repurchase approximately 5.9 million shares, including approximately $37 million spent to acquire approximately 1.3 million shares within the third quarter. As of the end of the third quarter 2018, we have approximately $825 million remaining on our existing multiyear share repurchase authorization.

Income Taxes

During the three months ended September 30, 2018, we recorded income tax expense of $27 million compared to $35 million during the same period in 2017. In the third quarter 2018, our adjusted effective tax rate was 20%. We expect our 2018 adjusted effective tax rate will be approximately 19% - 21%. We expect our long-term adjusted effective tax rate will be approximately 23% - 25%.

Venator

Our former Pigments and Additives segment, now known as Venator, remains classified as held for sale on our balance sheet and treated as discontinued operations on our income statement. Huntsman currently owns 53% of Venator’s outstanding shares.

(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.

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.
