Signed Transition Amendment Agreement (TAA)

Corporación América Airports S.A. (NYSE:CAAP) ("CAAP" or the "Company"), one of the world’s leading private airport operators, announced today that its subsidiary, Inframerica Concessionária do Aeroporto de Brasília S.A. ("Inframerica"), has entered into an amendment agreement so-called Transition Amendment Agreement ("TAA") with the Brazilian Civil Aviation Authority ("ANAC") in connection with the renegotiation process of the Brasília Airport concession agreement in Brazil. CAAP holds a 51% equity interest in Inframerica, while Infraero, a Brazilian state-owned company, holds the remaining 49%.

The TAA, which was approved by the Brazilian Federal Court in April 2026, was executed following negotiations involving ANAC, the Ministry of Ports and Airports, and the Federal Court of Accounts.

Among other changes, the overall agreement with the Brazilian government provides for:

(i)		the replacement of the fixed concession fee with a variable concession fee,
(ii)		the exit of Infraero from Inframerica’s shareholding structure,
(iii)		the inclusion of 10 regional airports in the concession; and
(iv)		additional investments at Brasília Airport.

Given the material changes to the economic equilibrium of the Brasília Airport concession agreement, the Brazilian Federal Court required that a fast-track competitive public tender process shall be carried out in connection with 100% of the shares of Inframerica, which is expected to occur by December 2026. CAAP intends to participate in the tender process. If there are no bids, the amended concession would be automatically granted to Inframerica.

This milestone will improve the economic equilibrium of the concession as well as the quality of service of the airport.
