Carnival, Royal Caribbean, and Norwegian Cruise Line are taking a financial beating from the coronavirus - here's how much the companies predict it will hurt earnings this year

"There are still too many variables and uncertainties to make a reasonable forecast for 2020," Royal Caribbean Cruises, the parent company of Royal Caribbean International, said on February 13.

Royal Caribbean said at the time that it had canceled 18 cruises in Southeast Asia and changed the itineraries for other sailings — moves the company projected would take $0.65 per share off of its estimated 2020 earnings of $10.40 to $10.70. In the event Royal Caribbean has to cancel all cruises in Asia through the end of April, it would remove another $0.55 per share this year, the company said.

Norwegian Cruise Line Holdings, the parent company of Norwegian Cruise Line, said on February 20 that after canceling or changing 40 cruises in Asia across its three brands, it expects the coronavirus to lower its projected adjusted 2020 earnings of $5.40 to $5.60 per share by about $0.75 per share. The company added that the coronavirus could end up having a larger financial impact by discouraging people from booking cruises.

"The Company's financial performance could be materially impacted if travel restrictions and COVID-19 concerns continue for an extended period of time," Norwegian said.
