Summary of the operations completed by the Company with its own securities within the framework of the programme authorised by the Annual General Meeting of Shareholders of 3 May 2016 and 11 May 2017 As at 6 March 2017, Aéroports de Paris did not hold any treasury shares. The contract liquidity account had a credit balance of €17,345,434.28, the budget of €35 million authorised by the Board had not been fully called upon at that stage. As at that date, no position was open, with regard to buying or selling, within the framework of the share buyback programme. As previously reported, Aéroports de Paris implemented its share buyback programme under article L. 225-209 of the French Commercial Code and pursuant to the liquidity contract, in order to set up a share purchasing

scheme for the subscribers of the Group savings scheme (see paragraph below). In this context, a mandate was given to an independent provider on 24 November 2015, for a total of €24 million, at a maximum purchase price of €113 including costs. The share buyback programme ended on 29 December 2015 after the purchase of 224,290 shares, at an average price of €106.7. The share buyback programme was relaunched on 18 January 2016 until 26 January 2016, and then from 17 to 26 February 2016 and again from 17 to 22 March 2016. Shares allocated to the free allocation of Company shares programme were delivered to employees who subscribed to the programme on 4 May 2017. Creation of a share-ownership structure In the second half of 2015, the group made a commitment to create a share-ownership structure, which was finalised during the first half of 2016. It comprised two facets: on the one hand, an option for employees of the Company and its subsidiaries who are members of the Group savings plan in its latest amended version and for retired and early retired employees having retained shares in the plan, to acquire Company shares under preferential conditions and, on the other hand, a free and uniform allocation to the same employees of 12 Company shares, authorised by the Extraordinary General Meeting of Shareholders of 3 May 2016 and implemented on the same day by the Board of Directors.
