ENGIE held a conference call on September 24, 2018, 8:00 am Paris time. The full retransmission of the call is accessible on ENGIE website.

During this conference call, the schedule, the impacts and the technical aspects of the unavailability of Belgian nuclear power plants were recalled.

The Group confirmed its 2018 financial targets on net recurring income Group share (at the low end of the 2.45 to 2.65 billion euros range), on net debt / EBITDA ratio and on dividend. As a reminder, the Group also indicated that EBITDA would be slightly lower than the indication given to the market on March 8, 2018.

These objectives include the revision of the schedule for the unavailability of the Tihange 2 and Tihange 3 nuclear units on September 21, which represents an impact of approximately 250 million euros at Group EBITDA and net recurring income group share. Since the beginning of the year, the cumulative impact of the unavailability schedule revisions of the Belgian nuclear power plants amounts to approximately 600 million euros at Group EBITDA and net recurring income group share.
