Japan's biggest airline has picked Nomura Holdings and Goldman Sachs Group Inc as two of the joint global coordinators for its first share offering since 2012, said the sources, both of whom declined to be identified because the information was not public.
The issuance is expected to raise around 200 billion yen ($1.9 billion), one of the sources said.
No one was immediately available for comment at ANA outside of regular working hours.
The Nikkei newspaper reported in September that ANA was mulling a potential 200 billion yen share issuance.
ANA, like other airlines, is burning through cash to keep jets flying albeit with too few passengers. Though demand for domestic flights has recovered to about half of last year's level, helped by government-subsidised travel, it is flying only a fraction of its usual international schedule.
It has forecast a record operating loss of $4.82 billion for the year to end-March and is temporarily transferring more than 400 workers to other companies. Other staff are being asked to take pay cuts or unpaid leave.
Domestic rival Japan Airlines Co Ltd also said earlier this month it would raise $1.8 billion in a share sale to strengthen its finances.
While Japan has avoided the worst of the pandemic, faring far better than the United States and Europe, it is now experiencing a surge in new daily infections. The nationwide tally hit a new high above 2,000 for the third straight day on Friday, according to domestic media.
