Aena to Run Rio’s Galeao, Becoming Brazil’s Largest Airport Operator

Spain’s Aena won the concession to operate Rio de Janeiro’s Galeao international airport with a 2.9 billion reais bid, a deal that will make it the largest airport operator in Brazil by passenger share. The concession runs until 2039, is extendable by five years, and gives Aena full control of the airport. Aena said Galeao produced nearly 500 million reais of EBITDA in 2024, with a 48% margin and no debt; the airport handled about 18 million passengers last year and has capacity for 37 million.

Key Points

  • Aena’s 2.9 billion reais bid won the concession to operate Galeao until 2039, with a possible five-year extension, making it Brazil’s largest airport operator by passenger share (about 28%).
  • Galeao produced nearly 500 million reais of EBITDA in 2024, with a 48% margin and no debt; it handled about 18 million passengers last year and has 37 million passenger capacity.
  • The 6.5 million passenger cap at Santos Dumont is expected to support Galeao’s traffic; Aena said major expansion projects like a third runway are not required under the concession.

Spain’s airport operator Aena said on Tuesday that its successful bid to operate Rio de Janeiro’s Galeao international airport will make it the largest airport operator in Brazil by passenger share, covering roughly 28% of the country’s passenger traffic.

Aena’s winning offer of 2.9 billion reais ($552.3 million) secured the concession to run Galeao, Brazil’s third-busiest airport, in an auction held on Monday. The concession is set to run until 2039 and can be extended for an additional five years, giving Aena operational control of the international hub for the duration of the contract.

Speaking with analysts on Tuesday, Aena’s finance chief provided financial detail on Galeao’s recent performance. The airport generated earnings before interest, taxes, depreciation and amortization (EBITDA) of nearly 500 million reais in 2024, with a reported margin of 48%, and the operator said the airport carried no debt.

"This transaction happens at a price that we are very comfortable with, and should generate value for all our shareholders and stakeholders," CFO Ignacio Castejon said.

The acquisition expands Aena’s footprint in Brazil, where it already manages several airports including Sao Paulo’s Congonhas, the country’s second-busiest airport. Galeao handled about 18 million passengers in the previous year and has a stated total capacity of 37 million passengers, according to Aena.

Aena noted the concession will not require major additional expansion spending, citing that large projects such as the construction of a third runway are not necessary under the terms of the deal. The operator also highlighted that a 6.5 million passenger restriction at Rio’s Santos Dumont airport - expected to remain in place until the end of that airport’s concession - will be a supporting factor for traffic at Galeao.

Under the terms reported by Aena, the company will have full operational control of the hub through the concession period and any applicable extension. The operator framed the price paid and the airport’s recent financial metrics as supportive of shareholder value creation.

Key takeaways

  • Aena won the Galeao concession with a 2.9 billion reais bid and will operate the airport until 2039, with a possible five-year extension.
  • Galeao reported nearly 500 million reais of EBITDA in 2024 with a 48% margin and no debt; the airport handled about 18 million passengers last year and has capacity for 37 million.
  • The 6.5 million passenger cap at Santos Dumont is expected to support traffic flows to Galeao during the concession period.

Implications

The concession increases Aena’s scale in Brazil’s airport sector and concentrates a significant share of passenger traffic under its management. The financial metrics Aena reported for Galeao and the lack of immediate major expansion requirements are factors the company cited in assessing the transaction’s value proposition.

Risks

  • Concession duration and extension - the contract runs to 2039 and can be extended by five years, creating uncertainty about the long-term operating horizon and future terms.
  • Traffic dependence on regulatory limits at nearby Santos Dumont - the 6.5 million passenger cap at Santos Dumont is expected to support Galeao traffic, but changes to that cap could affect flows.
  • Capacity utilization - while Galeao has capacity for 37 million passengers, last year’s traffic was about 18 million, indicating reliance on future traffic growth to approach capacity assumptions.
