Huntsman Agrees to Sell its Chemical Intermediates and Surfactants Businesses to Indorama Ventures for $2.1 Billion

THE WOODLANDS, Texas – Huntsman Corporation (NYSE: HUN) announced today it has entered into a definitive agreement to sell its chemical intermediates businesses, which includes PO/MTBE, and its surfactants businesses to Indorama Ventures in a transaction valued at $2.076 billion, comprising a cash purchase price of $2.0 billion plus the transfer of up to approximately $76 million in net underfunded pension and other post-employment benefit liabilities. The $2.076 billion transaction value represents an LTM adjusted EBITDA multiple of approximately 8.0 times, which includes retained SG&A costs of about $30 million, a portion of which Huntsman expects to eliminate over time. Under the terms of the agreement, Indorama Ventures would acquire Huntsman’s manufacturing facilities located in Port Neches, Texas; Dayton, Texas; Chocolate Bayou, Texas; Ankleshwar, India; and Botany, Australia. The transaction is subject to regulatory approvals and other customary closing conditions and is expected to close near year-end.

Peter Huntsman, Chairman, President and CEO commented:

“This transaction further transforms Huntsman’s balance sheet and future.  It accelerates our ability to expand more in areas both downstream and complementary to our portfolio.  This is another milestone in our stated strategy to focus more on our downstream and specialty businesses where we will generate more stable margins and consistent, strong free cash flow. We are committed to retaining our strong investment grade balance sheet, repurchasing our shares, investing in organic research and select capacity expansions and acquiring strategic assets that are accretive to our earnings and create shareholder value.

“For Indorama Ventures, they will be acquiring a strong EO/PO derivatives business with a very experienced workforce and management team.  This is also a transformational opportunity for Indorama Ventures that provides them hundreds of product grades and thousands of customers. Huntsman looks forward to continuing to work with Indorama Ventures as a customer and manufacturing partner through long-term commercial arrangements, including propylene oxide supply.

“Huntsman intends to accelerate share repurchases under its existing $1 billion multi-year authorization after the close of this transaction.”

Aloke Lohia, Group CEO of Indorama Ventures, commented:

“This acquisition is a momentous propellant in our journey towards our stated goal of being a global, diversified chemicals company with multiple, and related earnings streams.”

BofA Merrill Lynch served as Huntsman’s financial advisor and Kirkland & Ellis LLP is acting as its legal advisor.

Non-GAAP Financial Measures

We use adjusted EBITDA to measure the operating performance of our business and for planning and evaluating the performance of our business segments 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. We provide adjusted EBITDA because we feel it provides meaningful insight for the investment community into the performance of our business. Adjusted EBITDA, as used herein, is 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 (g) further adjusted for certain other items set forth in the reconciliation of adjusted EBITDA to net income (loss).
