According to a Swiss finance journal, HNA Group is in talks to divest its interests in Gategroup, Swissport and SR Technics, as it shores up its balance sheet due to debt of US$49.8 billion. HNA is reportedly negotiating the selling price.

Candidates for the three Swiss aviation assets include Singapore's sovereign fund Temasek, as well as HNA's internal units, and a potential new Chinese fund financed by external investors.

HNA bought Swissport in 2015, followed by Gategroup and SR Technics in 2016.
