Issue of new VINCI shares, reserved for group employees in France in the context of its savings plan *

The combined general meeting of shareholders held on 17 April 2018, through its 17 th resolution, delegated to the Board of directors its power to make increases in the capital reserved for employees for a period of 26 months expiring on 16 June 2020.

The meeting of shareholders defined in this context the manner in which the issue price of the new shares is determined.

During its meeting held on 19 june 2018, VINCI Board of directors fixed terms and conditions of a capital increase reserved for group employees in France, this transaction being in keeping with the powers received from the general meeting of shareholders.
