THE WOODLANDS, Texas — Huntsman Corporation (NYSE: HUN) today reported fourth quarter 2017 results with revenues of $2,203 million, net income of $287 million and adjusted EBITDA of $360 million.

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

“2017 was a transformational year marked with significant milestones for our Company. We successfully separated our Pigments and Additives business, now called Venator, by IPO and completed a first follow-on offering in December. Combined with our cash flow and the $1.7 billion in net proceeds from Venator, we were able to pay down approximately $2.1 billion in debt during the year. This debt reduction enabled Huntsman to enter 2018 with the strongest balance sheet in its history, with a net debt to EBITDA ratio of 1.4x, which is well within investment grade metrics.

“With a stronger balance sheet, our focus will be to continue to invest in our operational reliability and organic growth. We expect to generate between $450 million and $650 million of free cash flow in the upcoming years. We will also pursue acquisitions that will create value, greater growth in our downstream business and stronger earnings. This morning we are enhancing our shareholder returns by increasing the dividend 30% and announcing a share repurchase program of up to $450 million.”

Segment Analysis for 4Q17 Compared to 4Q16

Polyurethanes

The increase in revenues in our Polyurethanes segment for the three months ended December 31, 2017 compared to the same period in 2016 was primarily due to higher MDI average selling prices and MDI sales volumes. MDI average selling prices increased due to strong market conditions in all regions. The increase in MDI sales volumes was more than offset by a decrease in MTBE sales volumes resulting from the timing of MTBE shipments. The increase in adjusted EBITDA was primarily due higher MDI margins and sales volumes.

Performance Products

Revenues in our Performance Products segment for the three months ended December 31, 2017 compared to the same period in 2016 were essentially flat as higher average selling prices and improved mix were offset by lower sales volumes. Average selling prices increased primarily in response to higher raw material costs and favorable product mix. The decrease in sales volumes was primarily due to the sale of the European surfactants business to Innospec Inc. in 2016, as well as planned and unplanned outages at our Port Neches site. The decrease in adjusted EBITDA was primarily due to the sale of the European surfactants business

and higher costs, which includes the impact of the outages in the quarter, partially mitigated by continued margin improvement in our maleic anhydride business.

Advanced Materials

The increase in revenues in our Advanced Materials segment for the three months ended December 31, 2017, compared to the same period in 2016, was primarily due to higher average sales prices. Average selling prices increased primarily due to sales mix, as sales volumes in our higher value specialty business increased across all of our core markets. This growth in revenues was partially offset by lower sales volumes in our lower value wind and other commodity markets. Adjusted EBITDA increased due to higher specialty sales volumes and lower fixed costs, partially offset by higher raw material costs.

Textile Effects

The increase in revenues in our Textile Effects segment for the three months ended December 31, 2017 compared to the same period in 2016 was primarily due to volume growth, partially offset by lower average selling prices and unfavorable product mix. Sales volumes increased in the Americas, Europe and China. Average selling prices decreased primarily due to lower raw material costs. The increase in adjusted EBITDA was primarily due to higher sales volumes.

Corporate, LIFO and Other

Adjusted EBITDA from Corporate, LIFO and Other decreased by $1 million to a loss of $53 million for the three months ended December 31, 2017 compared to a loss of $52 million for the same period in 2016.

Held for Sale and Discontinued Operations

Our former Pigments and Additives segment, now known as Venator, is now classified as held for sale on our balance sheet and treated as discontinued operations on our income statement. Please refer to the Form 8-K we filed on October 31, 2017 with certain restated historical financial data. Huntsman currently owns 53% of Venator’s outstanding shares.

Liquidity, Capital Resources and Outstanding Debt

During the fourth quarter of 2017, we generated adjusted free cash flow of $190 million compared to $133 for the same period 2016. As of December 31, 2017, we had $1,247 million of combined cash and unused borrowing capacity compared to $1,208 million as of December 31, 2016. For the full year 2017, including the approximate $1.7 billion debt repayment made with the proceeds of the Venator separation, we repaid approximately $2.1 billion of debt. In connection with this debt reduction, Huntsman has repaid in full its senior secured term loan facility under its Senior Credit Facilities.

During the full year 2017, we spent $282 million on capital expenditures compared to $318 million in 2016. We expect to spend approximately $325 million on capital expenditures in 2018.

Income Taxes

During the three months ended December 31, 2017, we recorded an income tax benefit of $14 million compared to income tax expense of $44 million during the same period in 2016. This 2017 fourth quarter income tax benefit is largely the result of the new U.S. tax law, including a revaluation of our U.S. deferred tax liabilities at a lower tax rate partially offset by transition taxes on the deemed repatriation of deferred foreign income. In the fourth quarter 2017, our adjusted effective tax rate was 23%. Our 2018 estimated adjusted effective tax rate will be approximately 21% - 23%, which includes the benefit of the recent U.S. income tax reform.

The Board Approved a 30% Dividend Increase and Share Repurchases of up to $450 Million

Effective February 7, 2018, our Board of Directors approved an increase in our quarterly per share dividend from $0.125 to $0.1625. In addition, it authorized our Company to repurchase up to $400 million in shares of our common stock in addition to the $50 million remaining under our September 2015 share repurchase authorization. Repurchases may be made through the open market or in privately negotiated transactions, and repurchases may be commenced or suspended from time to time without prior notice. Shares of common stock acquired through the repurchase program are to be held in treasury at cost.

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 interest, 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 of discontinued operations; (h) U.S. tax reform impact on minority interest; (i) loss (gain) on disposition of businesses/assets; (j) loss on early extinguishment of debt; (k) expenses associated with merger, net of tax; (l) certain legal settlements and related (income) expenses; (m) net plant incident costs; (n) amortization of pension and postretirement actuarial losses (gains) and; (p) 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; (c) loss (income) from discontinued operations; (d) minority interest of discontinued operations; (e) U.S. tax reform impact on minority interest; (f) U.S. tax reform impact on tax expense; (g) loss (gain) on disposition of businesses/assets; (h) loss on early extinguishment of debt; (i) expenses associated with merger, net of tax; (j) certain legal settlements and related (income) expenses; (k) net plant incident costs; (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.
