This communication does not constitute or form part of and should not be construed as, an offer to sell or issue or the solicitation of an offer to buy or otherwise acquire securities of the Galp Energia, SGPS, S.A. (Galp) in any jurisdiction or an inducement to enter into investment activity in any jurisdiction.

Amorim Energia, BV launches a private offer for the sale of Galp Energia SGPS, S.A. shares, representing up to 5% of Galp share capital through an accelerated bookbuilding

Galp informs that the following announcement was received from the shareholder Amorim Energia:

"AMORIM ENERGIA, BV ("AEBV") announces it intends to sell up to 41,462,532 shares (the "Shares") representing 5% of the share capital of GALP ENERGIA SGPS, S.A. ("GALP").

The participation to be sold corresponds to the participation acquired by AEBV from ENI in July 2012 for the purpose of enabling ENI's exit from GALP's share capital, which resulted in an increase of AEBV's direct participation in GALP from 33.34% to 38.34%.

Therefore, upon the sale of the Shares now envisaged, AEBV will maintain a participation corresponding to 33.34% of the share capital of GALP and will maintain its position as GALP's reference shareholder.

Accordingly, AEBV hereby announces that it is launching a private offering of the Shares via an accelerated bookbuilding addressed exclusively to qualified institutional investors, in view of the sale, within such offer, of the Shares (the "Offer").

Société Générale Corporate & Investment Banking is acting as Sole Bookrunner of the Offer.

Pursuant to the Offer, AEBV also commits to observe a 180 days lock-up period (commencing on the settlement of the Offer) with respect to the sale of any of the remaining shares of GALP held by it at the date hereof, subject to customary exceptions and waiver by the Sole Bookrunner.

The final terms of the Offer will be announced upon completion of the accelerated bookbuilding procedure which is expected to occur during the course of tomorrow.
