Lufthansa will exercise an option to raise its ITA Airways holding from 41% to 90% by buying an additional 49% stake.
The second block of shares costs €325 million ($382 million) and is slated for payment next month, with closing expected in Q1 2027.
Transaction awaits EU and U.S. regulator approval; Lufthansa integrates ITA as its network airline and plans a Rome hub for South America.
The move reflects accelerating consolidation among European airlines.
