HAH reported in a press release:

Over recent months Heathrow Airport Holdings group shareholders and management have been considering their strategic position in relation to our three airports, Aberdeen, Glasgow and Southampton. As a result the group is now formally entering a sale process. While there is currently no certainty that a sale will be concluded, the group intends to work towards completing a transaction by the end of the year.

According to sources Spanish transport infrastructure firm Ferrovial is planning to secure complete ownership of three airports. The Spanish firm could have tabled an £800 million bid. Ferrovial is HAH's biggest shareholder, with a 25% stake.
