Termination of current share buyback program

Pursuant to the share purchase agreement entered into by Technip with an investment services provider on August 3, 2016 (see press release of August 4, 2016), which terminated on November 25, 2016, Technip has purchased 3,093,601 Technip shares under its share buyback program.

Implementation of new share buyback program

Technip signed today a new agreement with the same investment services provider for the purchase of up to 74,555 additional Technip shares before December 31, 2016 in furtherance of its share buyback program, in line with its stated policy to neutralize the dilution created by the scrip dividend, provided that the price per share does not exceed the maximum purchase price approved by the Annual General Meeting of April 28, 2015 (i.e. € 65).

Any such additional share bought back by Technip as well as the 3,093,601 shares bought back under the terminated share purchase agreement will be cancelled.
