[E1-ESRS 2 IRO-1-AR 11-(a)] → Climate-related risks have been identified in the short, medium and long term Climate events have been identified for the short term (one year), medium term (up to 2030) and long term (up to 2050). For the forecasts, the three time horizons considered are in line with the expected life of the assets or concessions and the indications of the EU Taxonomy: u baseline: average between 1985 and 2014; u 2030: average between the values for 2015 and 2044; u 2050: average between the values for 2035 and 2064. The 2030 horizon is being studied to define the levers to be activated quickly ( e.g. , prioritisation of actions, budget planning, etc.) while long-term studies aim to guide the Group’s strategic and structural decisions. [E1-ESRS 2 IRO-1-AR 11-(a)] → The company has checked whether its assets and business activities could be exposed to climate-related hazards The risks used for the analysis of gross risks are those of the IFRS Foundation (International Financial Reporting Standards):

In accordance with AR 10, detailed information is available in sections ESRS E1-1 paragraph 16, ESRS E1-4 and ESRS E1-6. With regard to adapting to climate change, Groupe ADP has undertaken studies to precisely examine the nature and impact of events that present a climate risk for its airports (both on infrastructure and on the continuity of operations) with a view to proposing a clear adaptation strategy according to local specificities. These studies focus on: u the risks and opportunities of the transition to a low carbon economy; u physical risks, which include the direct effects of climate change, whether chronic (rising temperatures, rising sea levels, etc.) or extreme (heat waves, flooding, etc.). PHYSICAL CLIMATE RISK ANALYSIS PROCESS [E1-ESRS 2 IRO-1-20-(b)] → Process for identifying climate-related physical risks The analysis of climate-related physical risks is fully integrated into Groupe ADP's risk management strategy. Groupe ADP assesses the way in which its assets and economic activities are exposed to climate risks in two stages: Between the end of 2022 and 2023, Groupe ADP conducted a gross risk analysis that did not include current or future risk mitigation or adaptation measures. This analysis of the airports' exposure to climate risks has made it possible to identify the most critical sites and to map the climate perils that have the greatest impact (based on the European taxonomic classification of climate-related risks) (for more details, see section E1-3 – Adaptation plan: physical climate risks and transition risks). In 2024 and 2025, we continued to assess the exposure of our assets to physical risks by analysing the net physical climate risks for airports controlled by the Group, backed up with site visits. This second stage of the analysis defines the vulnerability to climate-related hazards of the various airport processes (terminal operations, road access and car parks, airside and sensitive equipment). The aim is to take account of existing and planned mitigation and adaptation measures in qualifying the risk. The analysis includes an assessment of the cost of additional risk mitigation and adaptation measures that may be implemented as well as an assessment of the impact of the net risk on the value of the assets. The analysis is part of Groupe ADP’s proactive approach aimed at reducing vulnerability to climate risks and adapting airport infrastructures to the impacts of climate change, in particular by focusing on solutions adapted to local specificities. In 2024, a net risk analysis was carried out for the three Paris hubs and work began on Amman Airport (Jordan). These net risk analyses will lead to the definition of action plans to increase the resilience of our assets and activities to climate change. Elements of the methodology (time horizons, climate scenarios, assessment of the impact of hazards, etc.) are detailed in the remainder of section E1.IRO-1.

These climate hazards have been identified using measurable indicators. By way of example, here are a few indicators: u for temperature-related hazards: u combined heat index (in days): index constructed by taking a weighted average of the number of uncomfortable (27-32°C), very uncomfortable (33-39°C), dangerous (40-52°C) and very dangerous (> 52°C) days, with increasing weightings, u cooling degree days (in °C): index describing the cooling energy requirements of buildings (calculated by adding the differences between the average daily outside temperature and 18°C);
