EasyJet's board has rejected a $6.3 billion takeover bid from US investment firm Castlelake, with some reports describing the offer as "opportunistic" and part of a hostile takeover bid. However, there are conflicting reports on the outcome, with one outlet suggesting that EasyJet has agreed to a takeover offer from Castlelake, although the terms and details of this potential agreement are unclear.
