In late July, easyJet announces a 70% drop in third-quarter profit from the previous year, to £85 million, or nearly €100 million.
In all, 97% of voting shareholders vote in favor of the acquisition, easyJet stresses in a statement. The deal is valued at £5.7 billion, or about €6.8 billion.
According to Reuters, 97.07% of the shares covered by the buyback mechanism vote in favor of Apollo's offer.
The vote comes as the conflict in the Middle East is dramatically driving up the cost of kerosene and weighing on airlines. Many of them had, however, secured a large share of their supplies before the start of the war between the United States and Iran, when prices were much lower.
The airline will publish its full annual results later this month.
Rival Ryanair announced last week a cost-cutting plan and a fare increase next year, in order to offset the impact of the surge in aviation fuel prices.
The takeover of easyJet still faces regulatory hurdles in the European Union. According to Reuters, a majority of the capital must remain held by European investors.
