RISK FACTORS AND INTERNAL CONTROL 2 RISK FACTORS

3 – B: RISKS RELATED TO PORTFOLIO MANAGEMENT Poorly managed maintenance of its portfolio could have negative effects on Groupe ADP’s operations Criticality + Change in 2024 è Detailed description of the risk factor

Potential effects for the Group u Impact on airport operations u Additional financial costs not initially planned u Damage to image/reputation Interconnected risks u Risks related to the economic trajectory u Risks related to quality of service u Risks related to the management of major projects u Risks related to the effects of climate change

Groupe ADP is bound to provide its customers with facilities in good working order. Both internationally and in the Paris region, regulatory or concession contracts generally set targets for the quality and availability of facilities, the non-compliance of which may be accompanied by sanctions or penalties. The maintenance of the portfolio requires financial resources in OpEx (current maintenance) and CapEx (major maintenance, renovations, renewals, etc.). Failure to master one of these two points may result in: u short-term effects on Groupe ADP’s image or quality of service (breakdowns of critical facilities); u economic effects (emergency repairs to facilities not provided for in the allocated budgets); u losses in operations or service capacity (need to close all or part of an installation for safety reasons or non-operation of an installation that has become obsolete); u an accumulation of renovations/renewals to be carried out could generate a long term risk to the sustainability and operability of existing infrastructures, with an impact on major projects and the adaptation of assets to climate change.

MAIN RISK MANAGEMENT SYSTEMS At all of the airports managed by the Group, infrastructure maintenance presents challenges in terms of security, image, customer satisfaction (airlines, passengers), operational effectiveness and relations with the supervisory authority (French Civil Aviation Authority ( Direction Générale de l’Aviation Civile – DGAC), for Paris region hubs) or the concessionary authority at international level. The asset maintenance programme of Groupe ADP, managed on a multi-year basis, remains one of its main priorities. The performance of routine maintenance on the various facilities is monitored on a daily basis by the various technical processes of each platform through a single tool (CMMS) for the Paris region hubs which summarises the whole. Groupe ADP has decided to invest in a new CMMS solution to better meet the needs of maintenance staff (user friendliness, mobility, interoperability, reporting, etc.). For more than ten years, and more particularly during the 2024 Olympic and Paralympic Games, the teams have been committed to renovating/renewing the facilities/infrastructure within the framework of the specific obsolescence budgets allocated by the Finance Department and monitored by the project management divisions of each platform, in order to guarantee the operability of facilities and the highest level of service quality.

The state of the Paris region hubs and the resources needed to maintain them in operational condition are monitored by the Strategic Investment Committee. The long-term investment programme, managed on a multi year basis, takes into account the CapEx required to maintain the assets in order to stabilise the condition of its Paris region hubs. The monitoring of allocated budgets, the performance of routine maintenance and obsolete investment projects are governed by specific indicators that are regularly reviewed. In other countries where the Group operates, infrastructure maintenance is continuously monitored under the concession agreements between the concessionary authorities and Groupe ADP’s international entities.
