FINANCIAL RELEASE

September 27^th, 2023 

Aéroports de Paris SA
Groupe ADP took note of the French government's proposal for a new tax applicable to certain major transport infrastructure in France, including ADP SA's

Groupe ADP took note of the finance bill for 2024, adopted today by the Council of Ministers. The bill plans to introduce a new tax applicable to certain French transport infrastructure companies, including Aéroports de Paris SA (ADP SA).

The bill provides for a 4.6% tax applicable to the revenue, as stated in Aéroport de Paris SA's annual accounts, notably excluding revenues from airport safety and security services, and after the deduction of a 120 million euros exemption. The tax base would therefore have been 2,175 million euros as of December 31^st, 2022¹ (to be compared with 2022 consolidated revenue of 4,688 million euros). On this basis, the tax would have had an impact of c.100 million euros, on ADP SA's operating expenses (taxes other than income taxes), reducing the group's EBITDA by the same amount.

The group estimates that c.75% of the additional expense related to this tax would be attributable to the regulated scope, and c.25% to the non-regulated scope.

The portion of the tax attributable to the non-regulated scope could not be passed through and would remain borne by the group.

Pursuant with the French Transport Code and subject to the annual tariffs' approval by the Transport Regulation Authority (ART), Aéroports de Paris SA intends to pass the increase in regulated expenses through the tariffs. The tariffs' increase would be phased in two to three years, as to contain its impact on airlines and to comply with the principle set in the law of "moderate" yearly changes in tariffs. The first increase, covering around half of the impact from the tax, would be applied for the 2024 tariff-period². Further increase(s) would be applied to the subsequent tariff period(s).
