4 SUSTAINABILITY REPORT GENERAL DISCLOSURES

Material impacts associated with ESRS E4 Description of material impacts related to biodiversity: Groupe ADP has identified "Limiting pressure applied on biodiversity" as a material matter for its activities Airport activity itself is likely to have an impact on the biodiversity present at airport hubs. Groupe ADP's activities are likely to have an impact on biodiversity, particularly through urbanisation and infrastructure development. In particular, certain ecosystems and species may be affected if measures are not taken to limit land use (in the case of construction work, for example). As an airport operator, Groupe ADP may need to seal ground in order to meet air traffic demand. This can have a potentially negative impact on certain species living in the vicinity. In addition, the airport sites occupied by Groupe ADP are major transit areas that can disturb existing natural ecosystems. Lastly, airport activities can have an impact on the modification or degradation of local habitats and species. Preserving biodiversity therefore involves limiting changes in land use. For the Social and Societal ESRS, a total of 11 issues were identified as material. They are split into four sections: u three matters linked to S1; Material impacts associated with ESRS S1 Description of the material impacts linked to the "Health and safety of employees" matter Groupe ADP has identified "Health and safety of employees" (Own workforce/S1) as a material matter. The actions taken by each Group entity to protect their physical integrity and strengthen the prevention culture are constant. The Group 2025-2029 HR Roadmap includes a focus on protection, and in particular promoting a shared prevention culture, as set out in the Group Health and Safety at Work Charter. The Group's Human Rights commitments also incorporate this dimension. In the event of an accident with lasting consequences, the associated negative impact can be significant for employees and those close to them. Positive impacts include the development of measures to protect employees and improve working conditions. Description of the material impacts linked to the "Securing skills and making jobs more attractive" matter Groupe ADP has identified the challenges of “Securing skills and making jobs more attractive” as key matters. This topic is fundamental to ensure the Group's business, its development and its evolution, on the one hand, and on the other hand, to offer jobs and professional development to its employees, which will also benefit their families and the regions concerned. u two matters for S2; u three matters on S3; u three matters linked to S4.

DETAILED DESCRIPTION OF MATERIAL IMPACTS BY ISSUE For the Environmental ESRS, a total of six matters were identified as material. They are split into three levels: u three matters linked to E1 (climate change), i.e. , mitigating and adapting to climate change and developing new energy sources; u two matters for E2 (pollution), i.e. , air and water pollution; Description of the material impacts related to "Climate change mitigation and adaptation and development of new energy sources" The air transport sector is at the forefront of climate change issues. Airport operations contribute directly to these issues, as air traffic is responsible for greenhouse gas emissions that contribute to climate change. Groupe ADP is developing new technologies and energies to transform its platforms into energy hubs. It is therefore seeking to limit its impact on climate change by decarbonising its activities and promoting environmental transition, with the ultimate aim of reducing its carbon footprint on its airport sites. Material impacts associated with ESRS E2 Description of the material impacts associated with the "Limiting our impact on air quality" matter As air transport is a source of emissions of fine particles and regulated pollutants, Groupe ADP has identified "Limiting our impact on air quality" as a material matter for its activities. Airport activity is itself responsible for pollution linked to the production of the energy needed to keep airport facilities running smoothly and to the movements of passengers and airport workers travelling to airports. Activity at the airport, particularly air traffic and vehicle traffic that creates road transport hubs, is a major factor in the local impact on air quality. This situation can have a negative impact on: u people living around airports; u airport customers and staff. This underlines the importance of taking measures to reduce In the event of pollution, this could also have the knock-on effect of polluting natural surface environments and sources of drinking water for local residents and airport customers. The anticipated effects on Groupe ADP, in the event of pollution, have been identified, including significant costs associated with potential clean-up operations, as well as the non-operability of assets, which could even lead to temporary operational stoppages. atmospheric pollutant emissions in these areas. Description of the material impacts associated with the "Controlling water pollution" matter u one matter linked to E4 (biodiversity). Material impacts associated with ESRS E1
