PRESENTATION OF THE GROUP 1 GROUPE ADP’S ACTIVITIES

1.1.2.1.4 Outlook Groupe ADP anticipates a gradual return of air traffic to pre crisis levels over the coming years. Thus, the number of passengers welcomed in 2019 at Paris Aéroport should be recovered between 2025 and 2026 and may be exceeded in 2026. Growth in air traffic is expected to continue in the long term due to the economic growth of the various regions of the world and Paris’ positioning as a leading tourist and business centre. The Group expects this growth in traffic volume to be accompanied by a gradual change in the traffic mix in favour of international, which creates more value for the Group. The more reasoned use of aircraft and the increasing use of other modes of transport on short and medium-distance journeys should naturally contribute to reducing the share of short and medium-distance journeys in favour of international routes (excluding Europe) which contribute more to the total traffic at Paris Aéroport. This outlook does not take into account Groupe ADP’s strategy of making its platforms multimodal hubs, which should further strengthen this development. The annual growth rate of air traffic in the medium and long term could be lower than that of the years preceding the Covid crisis, reflecting a slowdown in air transport faced with a more restrictive regulatory framework and committed to an ambitious decarbonisation trajectory. The reference traffic scenarios taken into account to date for Paris traffic forecast an average annual growth rate over the 2019-2050 period of between 1% and 1.5% per year, compared to 2% per year over the 2000-2019 period.

Aéroports de Paris comes under the scope of application of this provision. The Company operates a group of Class 1 airports for which the annual costs per boarded passenger eligible for financing by the tax exceeded €9 on average over the last four known civil years. As a result, as from 1 January 2025, 8% of the costs attributable to tasks covered by the tax are borne by Aéroports de Paris, as compared to 6% previously. This remaining cost is also referred to as the "co-payment rate". Based on Aéroports de Paris SA’s security costs of between €500 million and €600 million per year in the coming years, the impact of this co-payment on the Company’s profit/loss from operating activities amounts to between approximately €42 million and €47 million per year, compared with €30 to 35 million previously. The Group continues to invest in safety and security at the Paris hubs. The most significant investments in the coming years concern the deployment of EDS detection equipment 1 standard 3 at Paris-Charles de Gaulle and Paris-Orly, as well as perimeter protection measures at Paris-Charles de Gaulle, Paris-Orly and Paris-Le Bourget. Advances to airport operators affected by the Covid-19 crisis for safety-security expenses Faced with the decline in air traffic impacting passenger air transport tax revenues, Aéroports de Paris was able to benefit in 2020 from €121.8 million of the total amount of €300 million of the advances to airport operators programme for airports affected by the Covid-19 crisis in respect of safety and security expenses in order to finance operating and investment expenses relating to safety and security missions. This cash advance was renewed by the successive finance laws in 2021 (€118.9 million allocated to Aéroports de Paris out of the total national credit of €250 million) and 2022 (€15 million allocated to Aéroports de Paris out of the total national credit of €150 million). The terms of payment and repayment of this advance are set by agreement with the France Trésor agency and the DGAC. The annual repayments relating to the advances granted in 2020 and 2021 were made in September 2024, and will be completed in 2030. Repayment of the annual instalment of the 2022 advance will begin in 2026 and end in 2032. The revenue from the tax will contribute to the repayment of the principal and the payment of the interest of the advances thus granted by the French State. 1.1.2.2 Retail and Services This segment covers all the retail activities of the Paris airports (including shops, bars and restaurants, car parks, terminal rentals) and activities of the retail subsidiaries: u retail sales subsidiaries: Extime Duty Free Paris (formerly SDA, which integrates SDA Croatia) and Extime Travel Essentials Paris (formerly Relay@ADP); u catering subsidiary: Extime Food & Beverage Paris; u advertising subsidiary: Extime Média; u subsidiaries acquired by Groupe ADP in October 2024: Paris Experience Group et Extime PS inc.
