STORY: Wizz Air shares fell just under a quarter on Thursday (June 5).

Investors fled the stock after the budget carrier reported yearly operating profit well below analyst expectations.

The Hungarian airline said it hit just over $191 million of operating profit for the financial year.

It was down close to 62% from a year ago.

WIzz was hit by capacity constraints due to ground planes, and also faced stubbornly high costs.

European airlines have warned of longstanding delivery delays.

Wizz Air in particular has been affected by repair problems with RTX-owned Pratt and Whitney engines, which hurt its ability to increase capacity.

CEO Jozsef Varadi said the carrier is resilient and blamed the year’s challenges on grounded planes.

Europe’s airlines have also pointed at uncertainty around keeping post-COVID demand.

Particularly with economic turmoil tied to U.S. President Donald Trump’s tariff threats.
