The announcement sparked strong investor interest, with easyJet's U.S.-traded shares surging nearly 10% following news that the investment firm is exploring a potential acquisition.
In a statement released on Friday, Castlelake stressed that discussions remain at a preliminary stage and that no formal approach has yet been made to easyJet's board.
“No approach has been made to the board of easyJet and there can be no certainty that any offer will be made, nor as to the terms of any offer,” Castlelake said.
Under the United Kingdom's takeover regulations, the investment firm now faces a deadline of June 26 to either submit a formal bid or withdraw its interest.
The development comes at a challenging period for easyJet, which recently cautioned investors that uncertainty continues to cloud its full-year outlook. The airline cited rising fuel costs and softer-than-expected summer bookings, pressures linked partly to ongoing geopolitical tensions in the Middle East.
The conflict involving Iran has created turbulence across the global aviation industry, contributing to a sharp increase in jet fuel prices and forcing airlines worldwide to reassess operating costs and ticket pricing strategies. Industry operators have faced the difficult choice of raising fares, reducing flight capacity, or accepting lower profit margins amid disruptions affecting key shipping and energy routes.
Despite remaining one of Europe's largest budget airlines, easyJet has struggled in the stock market this year. The company currently carries a market valuation of approximately £3.02 billion, while its shares have declined by more than 22% since the beginning of the year. The stock closed at 398 pence on Friday before news of Castlelake's interest boosted sentiment among investors.
For Castlelake, the potential move would represent another major bet on the aviation sector. The investment firm has steadily expanded its footprint in airline financing and aviation assets in recent years.
Earlier this year, Castlelake entered discussions to acquire Spirit Airlines, although those talks came after the U.S. carrier had already entered bankruptcy proceedings. Spirit subsequently ceased flight operations and exited the market.
In 2024, Castlelake also launched Merit AirFinance, an aviation finance platform backed by approximately $1.8 billion in deployable capital. The venture focuses on providing financing solutions to airlines and aircraft leasing companies seeking to acquire both new and used aircraft.
The possibility of a takeover has revived memories of easyJet's resistance to consolidation efforts in the past. In 2021, the airline rejected an acquisition proposal from Hungarian low-cost rival Wizz Air, choosing instead to raise about $1.7 billion from shareholders and pursue an independent growth strategy as the aviation industry emerged from the COVID-19 pandemic.
Whether Castlelake proceeds with a formal offer remains uncertain, but the firm's interest has already reignited speculation about consolidation within Europe's highly competitive budget airline market. Investors will now be watching closely ahead of the June 26 deadline to see whether Castlelake transforms its preliminary assessment into a concrete takeover proposal.
