SOCIAL, ENVIRONMENTAL AND SOCIETAL RESPONSIBILITY INFORMATION 17 , APPOINTED AS INDEPENDENT THIRD PARTY, ON THE CONSOLIDATED NON-FINANCIAL STATEMENT PUBLISHED IN THE GROUP MANAGEMENT REPORT

◆ For the key performance indicators and other quantitative outcomes 1 that in our judgment were of most significance, we carried out: ◆ analytical procedures that consisted in verifying the correct consolidation of collected data as well as the consistency of changes; ◆ substantive tests, on a sampling basis, that consisted in verifying the proper application of definitions and procedures and reconciling data with supporting documents. These procedures were conducted for a selection of contributing entities 2 and covered between 24% and 70% of the consolidated data for the key performance indicators and outcomes selected for these tests; ◆ We consulted documentary sources and conducted interviews to corroborate the qualitative information (measures and outcomes) that in our judgment were of most significance 3 ; ◆ We assessed the overall consistency of the Statement in relation to our knowledge of the company. We believe that the procedures we have performed, based on our professional judgment, are sufficient to provide a basis for a limited assurance conclusion; a higher level of assurance would have required us to carry out more extensive procedures. Means and resources Our work engaged the skills of six people between December 2018 and February 2019. To assist us in conducting our work, we referred to our corporate social responsibility and sustainable development experts. We conducted around ten interviews with people responsible for preparing the Statement. Conclusion The social indicators (except average staff number) do not cover TAV Airports, due to lack of data reliability as the internal control system is considered insufficient. Based on our work, except for the matter described above, nothing has come to our attention that cause us to believe that the non-financial statement does not comply with the applicable regulatory provisions and that the Information, taken as a whole, is not fairly presented in accordance with the Guidelines. Comments Without qualifying the conclusion expressed above and in accordance with Article A. 225-3 of the French Commercial Code, we make the following comments:

◆ As mentioned in the methodological note of the Statement: ◆ The scope of social indicators (except average staff number) relates only, for some indicators, to the Aéroports de Paris company that represents 24% of Group average staff number disclosed, and for other indicators, to the Group ADP excluding TAV Airports and AIG that represents 30% of Group average staff number disclosed; ◆ The average staff number of TAV Airports is disclosed in number of employees instead of full-time equivalent (FTE) as for the rest of the Group ADP because the FTE data is not available for TAV Airports; ◆ Some environmental indicators only relate to the three Aéroports de Paris airport platforms that represent 38% of the consolidated CO2 emissions from the three Parisian airport platforms of Aéroports de Paris and the three Turkish airport platforms of TAV Airports. ◆ The objectives defined by the environmental and energy policy disclosed in the Statement only relate to the Aéroports de Paris company. Nature and scope of procedures Regarding the information Frequency rate of workplace accidents with lost time Aéroports de Paris, Internal electricity consumption, we conducted work of the same nature as the work described in section 1 above but in further detail, in particular concerning: ◆ analytical procedures that consisted in verifying the correct consolidation of collected data as well as the consistency of changes; ◆ substantive tests, on a sampling basis, that consisted in verifying the proper application of definitions and procedures and reconciling data with supporting documents. The selected sample represents between 62% and 99% of this information. We believe that this work is sufficient to provide a basis for our reasonable assurance conclusion on this information. Conclusion In our opinion, the Information selected by the Company Frequency rate of workplace accidents with lost time Aéroports de Paris, Internal electricity consumption is, in all material respects, fairly presented in accordance with the Guidelines.
