The National Business Registration Portal shows the addition was made on April 17 from its previous charter capital of VND4.05 trillion ($173 million.)
However, its parent company FLC, a property developer, has not made any announcement about capital addition for Bamboo Airways; and the airline has not announced a change in ownership.
As of March 31, FLC had a 52.11 percent stake in the carrier.
With the adjustment, Bamboo Airways ranks second in terms of charter capital among five domestic airlines, behind flag carrier Vietnam Airlines, at 14.2 trillion ($607 million). Budget airline Vietjet ranks third with VND5.4 trillion ($231 million).
Bamboo Airways has announced plans to list on the Ho Chi Minh City Stock Exchange (HOSE), Vietnam’s main bourse.
The Vietnam Valuation and Inspection Quality Jsc, a business valuation company, has valued it at VND33.3 trillion ($1.4 billion).
The airline began flying in January 2019, and was operating on 40 domestic and international routes before the pandemic forced it to severely curtail operations.
