2 RISK FACTORS AND INTERNAL CONTROL RISK FACTORS

3 – C: RISKS RELATED TO THE MANAGEMENT OF MAJOR PROJECTS Groupe ADP is exposed to the risk of non-control of major projects Criticality + Detailed description of the risk factor Groupe ADP is exposed to the risk of non-control of large-scale projects. As part of its activity, Groupe ADP is required to carry out, as the contracting authority or project manager, infrastructure projects that are intrinsically complex and require significant investments and lengthy appraisal procedures and regulatory authorisations. The investment programme proposed by Groupe ADP for the 2023-2025 period is detailed in section 3.3 of this Universal Registration Document. Major projects are also characterised by a long investment cycle (from the design phase to commissioning). As a result, unexpected changes in the volume or structure of air traffic, for example, or significant technological developments, could lead to the latter being ultimately unsuited to requirements. In addition, existing infrastructure may be saturated while waiting for the delivery of new facilities. Lastly, returns on investments could be lower than expected and thus have a negative impact on Groupe ADP’s financial position and outlook. More generally, the completion of these projects may be subject to numerous technical, industrial, operational, economic, regulatory or environmental risks that may delay or even prevent their delivery.
