Manchete: Acionistas da Azul vão vender ações na bolsa em nova oferta
Headline: Azul’s stockholders to sell shares on market in new offering
A secondary offering is when stocks of shareholders are sold, not new

company issues; the company says the transaction does not change control of the company.
Airliner Azul requested on Tuesday (12) an offer of shares in Brazil and abroad involving an initial batch of 40.6 million.
The sale of stocks by shareholders (secondary offering) means the money raised goes to the shareholders in contrast to new company issues when the capital raised goes to the company.
