CHANGE IN MODAL SHARE OF PASSENGERS (PEAK - HOUR VEHICLE FLOWS)

In addition, a more detailed survey of passengers' modal choices was carried out from 30 March to 17 April 2024 (excluding strike days) between 5 a.m. and 11 p.m. Passengers were interviewed randomly in the boarding lounge to ensure that all profiles were representative. The questionnaires were filled in by passengers on a tablet, with help from the interviewer for the section simulating the future journey with the Grand Paris Express. The questionnaire was available in 7 languages (French, English, German, Italian, Spanish, Portuguese and Chinese). The following topics were addressed: u access to the airport for the day's journey; u reasons for choosing the mode of access to the airport; u simulation and projection of new modes of transport with the Grand Paris Express and testing of breakthrough scenarios; u information on the day's journey and socio-demographics. Adjustment of data by terminal, access mode, time slots, gender, age, socio-professional category, place of residence, frequency of journey, main nationalities based on results from the Observatory starting in 2022. These surveys are used to test the relevance of certain potential objectives that the Group could envisage in this area. [S4-5-41-(b)] → [S4] Information on how consumers and/or end-users have been directly involved in tracking performance against targets See paragraph 4.3.4.2 [S4-5-41-(b)] → [S4] Information on how consumers and/or end-users have been directly involved in tracking performance against targets. [S4-5-41-(c)] → [S4] Communication of how consumers and/or end-users have been directly involved in identifying lessons or improvements as a result of the company’s performance See previous paragraph and S4-1-AR-13. [S4-5-AR 42-(b)] → [S4] Information on the stability of the target in terms of definitions and methodologies to enable comparability over time The objectives have only recently been defined, so there is as yet no long-term monitoring of the methodology to enable comparability. For example, for the parking section, the targets have been monitored since 2021. However, a mobility observatory is currently being set up. It will go live at the beginning of 2025 and will be the main tool for monitoring changes in the metrics. The mobility observatory is a dashboard providing access to a multitude of data and metrics on mobility issues. The objectives of the observatory are: u drawing up an inventory of all the mobility data scattered across the various departments and completing data collection by subject (particularly on rail, active mobility and freight transport); u standardising, centralising and increasing the frequency of reporting on mobility; u providing easy, reliable access to mobility data.

For Paris-Charles de Gaulle airport The data presented below were collected in 2024. PAX MODAL SHARE

Monitored targets and metrics for parking u percentage use of digital technology in parking: >50% of bookings made online in 2025; u Service quality: ACI ASQ rating >3.85 for car park quality; u number of electric vehicle charging stations (BRVE): target of 1,000 charging points in 2025 (and 2,500 by 2030). [S4-5-41-(a)] → [S4] Disclosure of how consumers and/ or end-users have been directly involved in setting targets Regular surveys are carried out among end-users in the terminals. A quarterly questionnaire is carried out on user access methods.
