US firm ADC & HAS Airports Worldwide has bought Belfast international airport.
The Northern Irish airport has been owned by Spanish company Abertis since 2005.
Abertis is also selling Stockholm Skavsta airport and other assets to ADC & HAS for a total of €284 million.
ADC & HAS has interests in airports in Costa Rica and Ecuador.
Chief executive Jeff Scheferman said: “We are extremely pleased with this acquisition. With it, we add to our portfolio two airports serving capital cities.
“We also expand and intend to further build upon our presence in the US market, add more than 350 experienced airport personnel, and will be serving more than 35 million passengers annually.”
Belfast international is the second largest airport in Ireland and handles around 4.3 million passengers a year.
