The carrier, part of the sprawling and financially troubled HNA conglomerate, in April sold part of its stake in Azul to a subsidiary of United Airlines parent United Continental Holdings UAL.N for $138.3 million.
Hainan’s remaining stake, accounting for 17.95 percent of preferred shares and a 17.28 percent economic interest in the airline is worth around $324 million, based on Azul’s market value as of Tuesday’s close.
Hainan said the sale was a strategic decision in light of equity market conditions and that it would help the firm maintain liquidity and keep its asset restructuring on track.
HNA, the aviation-to-financial services conglomerate, has been selling overseas real estate and some of its biggest financial and strategic investments following a $50 billion acquisition spree over the past two years.
Azul was established a decade ago by David Neeleman, the founder of U.S.-based carrier JetBlue Airways Corp (JBLU.O), who remains the largest preferred shareholder with a 67 percent holding.
As of April, Azul had an 18.9 percent share of the Brazilian domestic market and a 15.4 percent share of the international market among Brazilian carriers, according to the country’s civil aviation authority.
