Ref.No.IVL004/11/2017

9th November 2017 President

The Stock Exchange of Thailand

Indorama Ventures Public Company Limited ("IVL") would like to inform that it will through its indirect subsidiary Indorama Netherlands BV (INBV) acquire the PTA assets of Artlant PTA

S.A. in Portugal with production capacity of 700,000 tons per annum.

In addition, INBV has also signed a definitive asset purchase agreement to acquire the adjacent utility assets of Artelia Ambiente, S.A. Portugal which has a capacity of 40 MW of electricity plus steam, demineralized water, wastewater treatment and hydrogen and supplies its utilities to the Artlant PTA plant.

PTA is a core strategic business of IVL and we are confident that over time the Portugal PTA plant will support the polyester value chain businesses in Portugal and in EMEA for the IVL group as well as for merchant markets. Due to financial difficulties of the founder, the assets which have practically produced for short periods are in mothballed but well maintained condition for startup by a new owner.

The value of the two assets calculated in accordance with the regulations of the Capital Market Supervisory Board and the Stock Exchange of Thailand, as prescribed by the regulations of the Stock Exchange of Thailand Re: Disclosure of Information and Other Acts of Listed Companies Concerning the Acquisition and Disposition of Assets, 2004 (as amended) is less than 15 percent and the total size of all transactions in the past 6 months also does not exceed the 15 percent threshold limits as prescribed in the regulations.

The transaction is expected to be completed within the fourth quarter of 2017. Please be informed accordingly.

Yours faithfully,

(Mr. Souvik Roy Chowdhury) Company Secretary
