Paris, 26 April 2011

Aéroports de Paris has become aware of rumours relating to a possible disposal of Alyzia group, specialized in ground handling services for airlines and airport security services.

Aéroports de Paris would like to point out that it has given some thought to the possible disposal of the majority of its stake in the capital of its subsidiary Alyzia holding. At this point in time no decision has been taken as to whether this will come about.

If Aéroports de Paris decided to proceed with this process, after the work that is currently underway is completed and subject to the matter being put before the workers councils and to the decision of its competent governing bodies, then Aéroports de Paris would inform the market about it.
