The three principal shareholders of Norwegian Cruise Line Holdings have filed to collectively sell 20 million shares of stock.
The divestment would reduce their controlling stake in the company from 86.7% to 76.9%.
Proceeds from the sale, about $600 million at current prices, would go to Genting HK, Apollo Funds and TPG Viking Funds.
Until a public offering earlier this year, the three entities had owned all of Norwegian Cruise Line.
After the sale, Genting's stake would fall from 43.4% to 38.5%; Apollo's stake from 32.5% to 28.8%; and TPG's stake from 10.8% to 9.6%.
Norwegian Cruise Line Holdings has about 204 million shares outstanding.Follow @tstravelweekly on Twitter.
