COMPANY FINANCIAL STATEMENTS OF AEROPORTS DE PARIS SA AT 31 DECEMBER 2024

NOTE 3 RELATIONS WITH SUBSIDIAIRIES 3.1 Tax consolidation In application of articles 223A and following of the General Tax Code, Aéroports de Paris SA operates under a tax consolidation system with French companies in which it directly or indirectly holds over 95% of the share capital. (see note 6.2). The tax consolidation agreements between Aéroports de Paris SA and its subsidiaries are based on the neutrality principle, according to which the tax payable by the subsidiaries is equal to the tax that would have been payable had no tax consolidation existed. 3.2 Cash management Aéroports de Paris SA has set up a cash-pooling system to which some French subsidiaries adhere, in compliance with the regulations in force. The main subsidiaries concerned are ADP International, ADP Immobilier, ADP Immobilier Industriel, ADP Immobilier Tertiaire, Hotels aéroportuaires, ADP Immobilier Activités, Ville Aeroportuaire Immobilier 1, ADP Invest, Hologarde, TANK Alpha, HUB One and its subsidiaries. Within this framework Aéroports de Paris SA has concluded with each member entity a treasury agreement with a view to centralizing the balances of bank accounts denominated in euros and US dollars. The daily and automatic leveling of subsidiary bank accounts by debit or credit of the centralizing account allows optimal management of the use of credit and the placement of excess cash. Advances made in euros by the centralising company to the subsidiaries bear interest monthly at ESTR +0.65%. Advances made in euros by the subsidiaries to the centralising company bear interest monthly at the ESTR rate. Advances made in US dollars by the centralizing company to the subsidiaries bear interest monthly at the SOFR overnight rate plus 0.65%. Advances made in US dollars by the subsidiaries to the centralising company bear interest monthly at the SOFR rate.

The tax consolidation agreements provide that: u the subsidiary is to pay the parent company the same amount as the tax it would have otherwise paid had it been taxable separately; u the subsidiary is not entitled to any receivables if it reports a tax loss.

Note that if the ESTR and/or SOFR rate less 0.07% were to be negative, the interest rate on the cash advances would be maintained at a floor of 0%. Specific conditions applied from 1 July 2021 to the subsidiary ‘TANK OWA ALPHA GMBH’: u advances made in euros by the centralising company to the subsidiary bear interest monthly at EONIA (or STR + 8.5 basis points), plus 3.75%; u advances made in euros by the subsidiary to the centralising company bear interest monthly at EONIA (or STR + 8.5 basis points). Note that if the €STR + 8.5 basis points rate is less than 0%, it will be considered to be zero. Under the cash pooling agreements between Aéroports de Paris SA and its subsidiaries, current accounts are presented as "Other receivables" when there is a debit balance and as "Payables on fixed assets and other payables" when there is a credit balance (see notes 6.3 and 6.11).
