Official Letter 1690/2017-SAE

 

 

“Ref.: Request for clarification on news report

 

Dear Sirs,

 

Complementing our official letter 1689/2017-SAE below, in light of the news item published in InfoMoney on 10/30/2017, entitled "Braskem escapes Ibovespa "sell off" and jumps 12% with rumor about acquisition; steel companies sink 5%”, mentioning, among others, that:

1.        The shares of Braskem skyrocket during this session after rumors about the company’s acquisition by LyondellBasell;

2.        The movement occurs after LyondellBasell approached Braskem for a possible acquisition, which could value the company at over US$ 10 billion.”

 

 

In this regard, Braskem clarifies that:

 

(i)                   it was not approached by LyondellBasell with any proposal for acquisition of its shares and is unaware of any other fact that could have justified the unusual trading on the Company’s shares between October 17, 2017 and October 30, 2017;

 

(ii)                 the suitability and timeliness of disposing of Braskem's shares is a decision that rests solely with its shareholders; and

 

(iii)                in this regard, the management of Braskem requested clarifications to Odebrecht,  its controlling shareholder, which informed that it keeps working on alternatives to add value to Braskem and for all shareholders, and reaffirmed its intention of keeping Braskem as part of the group investments.

 

For more information, contact Braskem’s Investor Relations Department by calling +55 (11) 3576-9531 or sending an e-mail to braskem-ri@braskem.com.br  

 

 

 

Sincerely,

 

 

Pedro Van Langendonck Teixeira de Freitas
