Skymark Airlines Inc., the nation's third-largest carrier, repeated it is at risk of going out of business should it have to pay Airbus Group NV a penalty after its planned purchase of six A380 superjumbos fell through.

The airline said there is "material uncertainty" over whether the company will remain a going concern and is negotiating with Airbus to reduce the "large amount" of penalty being sought, the carrier said in a statement Thursday. Skymark first flagged this concern in July.

Skymark on Thursday also predicted a loss of ¥13.7 billion ($126 million) for the fiscal year ending in March, reversing a previous forecast for a profit. The carrier paid ¥26.5 billion, more than the airline's market value, for the double-decker planes, including money to makers of the engines and other parts, it said in July.
