The coronavirus pandemic has rocked Carnival Corp's finances so hard that the large-cap company claims it can no longer reliably predict its own future.

The New York-listed cruise behemoth with 104 ships posted a $781m loss for the first quarter ended 29 February, marking its first three-month deficit ever in its history.

The Arnold Donald-led company also finds itself relying on almost $12bn in credit and loans to make good on newbuilding deliveries amid fleet layups and canceled voyages.
