THE WOODLANDS, Texas — Huntsman Corporation (NYSE: HUN) today reported third quarter 2017 results with revenues of $2,169 million, net income of $179 million and adjusted EBITDA of $340 million.

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

“While I am disappointed that the merger of equals agreement with Clariant has been terminated, Huntsman’s future has never been brighter as our businesses continue to improve across the board, our balance sheet is as strong as it has ever been and will get even stronger with proceeds from upcoming Venator secondary sales. We look forward to achieving investment grade metrics in the near future. Huntsman remains focused on growing our downstream differentiated and specialty businesses, expanding our margins, and generating a consistently strong free cash flow.”

“Notwithstanding a $50 million impact from Hurricane Harvey on our third quarter EBITDA, our business was up $113 million over last year. Our business is operating at a 16% EBITDA margin to sales. Excluding the impact from Harvey, each one of our businesses performed well, growing adjusted EBITDA versus the prior year, as our underlying fundamentals remain positive across our core markets. I expect each of our businesses to show year over year growth in the fourth quarter as well. In addition to our strong operating performance in the third quarter, we successfully completed the IPO of our Pigments and Additives segment, now called Venator, and the $1.2 billion in the initial proceeds were used to reduce our leverage. We also paid down an additional $100 million in debt from free cash flow earlier this week. We are delivering on our commitments to our shareholders, as to date we have generated over $1 billion in free cash flow and reduced our net-debt by over $2 billion since 2016, while at the same time investing in our differentiated and specialty businesses.”

Segment Analysis for 3Q17 Compared to 3Q16

Polyurethanes

The increase in revenues in our Polyurethanes segment for the three months ended September 30, 2017 compared to the same period of 2016 was due to higher average selling prices and higher sales volumes. MDI average selling prices increased in response to continued strong market conditions and higher raw material costs. MTBE average selling prices increased primarily as a result of higher pricing for high octane gasoline. MDI sales volumes increased due to increased demand across most major markets. MTBE sales volumes increased due to the timing of shipments in the 2016 period, partially offset by the impact of hurricane related production outages during the third quarter of 2017. The increase in segment adjusted EBITDA was primarily due to higher MDI margins, partially offset by lower MTBE earnings and the $15 million estimated impact of hurricane related production outages during the third quarter of 2017.

Performance Products

The decrease in revenues in our Performance Products segment for the three months ended September 30, 2017 compared to the same period of 2016 was due to lower sales volumes, partially offset by higher average selling prices. Sales volumes decreased primarily due to the sale of the European surfactants business to Innospec Inc. on December 30, 2016 as well as the impact of hurricane related production outages in the third quarter of 2017, partially offset by higher sales volumes in our maleic anhydride and amines businesses. Average selling prices increased primarily in response to higher raw material costs and a favorable product mix effect. The decrease in segment adjusted EBITDA was primarily due to the estimated $35 million impact of hurricane related production outages in the third quarter of 2017 and the sale of the European surfactants business at the end of 2016. Pro-forma for the sale of our European surfactants business, adjusted EBITDA was flat year-over-year.

Advanced Materials

The increase in revenues in our Advanced Materials segment for the three months ended September 30, 2017 compared to the same period of 2016 was due to higher sales volumes and higher average selling prices. Sales volumes increased primarily due to growth in our specialty electronics and electrical and coatings

components businesses, partially offset by our withdrawal from certain low margin business. Average selling prices increased in response to higher raw material costs and favorable product mix. The increase in segment adjusted EBITDA was primarily due to higher sales volumes and higher average selling prices, partially offset by higher raw material costs.

Textile Effects

The increase in revenues in our Textile Effects segment for the three months ended September 30, 2017 compared to the same period of 2016 was due to higher sales volumes, partially offset by lower average selling prices. Sales volumes increased in both textile chemicals and dyes, particularly in our Asia region. Average selling prices decreased primarily due to competitive market conditions. The increase in segment adjusted EBITDA was primarily due to higher sales volumes and lower fixed costs, partially offset by lower margins.

Corporate, LIFO and other

For the three months ended September 30, 2017, segment adjusted EBITDA from Corporate and other for Huntsman Corporation increased by $3 million to a loss of $42 million from a loss of $45 million for the same period in 2016.

Held for Sale and Discontinued Operations

Our Pigments and Additives division, known as Venator, is now classified as Held for Sale on our balance sheet and treated as discontinued operations on our income statement. We will be issuing a form 8K with certain restated historical financial data.

Liquidity, Capital Resources and Outstanding Debt

During the quarter we generated adjusted free cash flow of $227 million compared to $251 million a year ago. As of September 30, 2017, we had $1,211 million of combined cash and unused borrowing capacity compared to $1,208 million as of December 31, 2016. Year to date, including the $1.2 billion debt repayment made with the proceeds of the Venator separation and the $100 million early repayment of debt made on our term loan this week, we have repaid approximately $1.6 billion of debt.

During the nine months ended September 30, 2017, we spent $159 million on capital expenditures compared to $214 million in 2016. We expect to spend approximately $290 million on capital expenditures in 2017.

Income Taxes

During the three months ended September 30, 2017, we recorded income tax expense of $35 million compared to $6 million during the same period in 2016. In the third quarter 2017, our adjusted effective tax rate was 24%. We expect our fourth quarter adjusted effective tax rate to be similar to the third quarter. Our 2018 adjusted effective tax rate will be approximately 25% - 28%.

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. 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) Income (loss) from discontinued operations, net of tax; (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; (k) certain legal settlements and related expenses (l) net plant incident costs (credits); (m) amortization of pension and postretirement actuarial losses (gains); and (n) restructuring, impairment and plant closing costs (credits). The reconciliation of adjusted EBITDA to net income (loss) is set forth 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) acquisition and integration expenses, purchase accounting adjustments; (c) impact of certain foreign tax credit elections; (d) Income (loss) from discontinued operations, net of tax;; (e) discount amortization on settlement financing associated with the terminated merger; (f) loss (gain) on disposition of businesses/assets; (g) loss on early extinguishment of debt; (h) expenses associated with the merger; (i) certain legal settlements and related expenses; (j) net plant incident costs (credits); (k) minority interest from discontinued operations; (l) amortization of pension and postretirement actuarial losses (gains); and (m) restructuring, impairment and plant closing 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 Table 4 above.

(2) Pro forma adjusted to exclude the sale of our European differentiated surfactants business to Innospec on December 30, 2016 as if it had occurred at the beginning of the relevant period.

(3) 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.

(4) 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.
