1.1.2.1.1 Definition of the regulated scope In accordance with article L. 6325-1 of the French Transport Code ( Code des transports ), the amount of fees takes into account the return on capital employed for a scope of activities stipulated by regulation for each airfield, assessed based on the weighted average cost of capital estimated using the financial assets valuation model, available market data and parameters considered for companies engaged in comparable activities. The regulated scope of Aéroports de Paris is defined by the first article of the decree of 23 May 2024 relating to fees for services rendered in airports. The performance of the regulated scope is assessed by comparing the weighted average cost of capital to the return on capital employed (RCE or ROCE), calculated as the regulated scope's operating income, after normative income tax, and the regulated asset base, (net carrying amount of property, plant and equipment and intangible assets relating to the regulated scope, plus the working capital requirement for this scope). As of 31 December 2024, the ROCE of the regulated scope was 4.0%, compared to 5.6% as of 31 December 2023 1 . It corresponds to the ratio between the regulated scope’s operational income, after normative income tax, and the regulated asset base, used to assess the performance of the regulated scope in accordance with article L. 6325-1 of the French Transport Code.

Operating income of the regulated scope for 2024 amounted to €318 million before tax, versus €436 million in 2023. Since 1 January 2011, the regulated scope includes all the activities of Aéroports de Paris within the Paris region hubs, with the exception of: u general interest activities financed by the safety and security tariff of the passenger air transport tax, i.e. , security activities, prevention of animal hazards, rescue services and the fight against aircraft fires (SSLIA) 2 as well as the measurements carried out as part of environmental controls; u retail and service activities; u land and real estate activities not directly related to aviation activities or “real estate diversification” activities; u the management by Aéroports de Paris of assistance with soundproofing for local residents, through the tax on aircraft noise pollution 3 ; u ground-handling service activities falling within the competitive field; u other activities unrelated to the activity of the Paris region airfields.
