Norwegian Cruise Line — Norwegian’s stock dropped 13% after the closing bell after the company announced it is extending its suspension of global cruises to include trips between August 1 and September 30 for its three main cruise brands. The cruise line said the cancellations exclude Seattle-based Alaska trips in September. Select voyages, including Canada and New England itineraries, are also canceled through October 2020 due to travel and port restrictions. Shares of Carnival and Royal Caribbean Cruises each fell more than 7% in after-hours trading as well.
