British budget airline easyJet is in talks about a possible deal with U.S. investment firm Castlelake after rejecting a recent takeover approach.

The negotiations signal a potential shift in the European aviation landscape as a major low-cost carrier becomes a target for private investment. This interest follows a period of instability in the budget sector, including the collapse of Spirit Airlines.

Castlelake, based in Minneapolis, submitted its third formal approach on June 20 [6]. easyJet rejected the proposal on June 21 [7]. The airline said it declined the offer because the valuation and terms did not meet its expectations [10].

Reports on the total value of the bid vary. The Financial Times said the valuation was £4.9 billion [1], while other reports placed the figure between £4.7 billion [3] and £4.74 billion [2]. The third approach specifically offered 625 pence per share [4].

This latest move follows an earlier period of interest that began on May 29 [8]. When news of Castlelake's interest first surfaced, easyJet stock rose by up to 10 percent [5].

Castlelake said the acquisition is an opportunity to secure a major European low-cost carrier [10]. While the specific terms of the current discussions remain private, the transition from a rejected bid to ongoing talks suggests both parties are seeking a middle ground on valuation.

The pursuit of easyJet by Castlelake reflects a broader trend of institutional investors seeking undervalued assets in the volatile aviation sector. By rejecting the initial multi-billion pound offer but continuing discussions, easyJet is leveraging market interest to drive a higher valuation, while Castlelake is attempting to establish a strategic foothold in the European budget travel market.
