GDF SUEZ finalizes the disposal of Fluxys

On Wednesday May 5, 2010, Electrabel and Publigaz finalized the disposal of Electrabel S.A.'s holdings in Fluxys S.A. (38.50%). The disposal of 270,530 shares was completed at the price of € 2,350 per share, for a total amount of € 636 million. Through this transaction, the GDF Suez group completely withdrew from the capital of Fluxys S.A.

The parties also finalized the transfer of Electrabel's holdings in Fluxys LNG to Fluxys.
