Viking could be eyeing an initial public offering as soon as the second quarter of this year, according to a report from Bloomberg.

With a dominant position in the European river cruise market, a fleet of ocean-going cruise ships, two expedition ships, a joint venture in China and a Mississippi river operation, the company continues to expand in the cruise industry, with more riverboats and ocean-going ships on order.

If Viking were to list, it would join the other public cruise companies, including Carnival Corporation, Royal Caribbean Group, Norwegian Cruise Line Holdings and Lindblad Expeditions. Of those four, Lindblad was the last go to public in 2015.

According to Bloomberg, the IPO could raise over $500 million and Viking is said to be working with Bank of America, UBS, Wells Fargo and JP Morgan on the listing.
