EasyJet Rejects 4th Castlelake Bid as PUSU Deadline Looms

EasyJet Rejects 4th Castlelake Bid

EasyJet has rejected a fourth proposal from US-based Castlelake to acquire the airline, citing that the offer of 650p per share, valuing the company at £4.9 billion, significantly undervalues its market position and future prospects. According to the official regulatory filing, the board has requested an extension to the UK Takeover Panel's 'Put Up or Shut Up' (PUSU) deadline to 5:00 PM on July 5, 2026. This extension allows the airline to provide limited commercial information to the bidder, a move analysts suggest signals that a potential transaction remains viable.

Ownership Structures and Regulatory Hurdles

Castlelake, which currently holds a 2.14% stake in the airline according to LSE disclosure data, has proposed an acquisition structure designed to comply with strict regional aviation laws. Under Regulation (EC) No 1008/2008 of the European Parliament and Council, airlines operating within the bloc must be more than 50% owned and effectively controlled by EU Member States or their nationals. To navigate this, Castlelake has proposed a new group structure where it would hold a 49% stake, while the remaining 51% would be held by EU citizens.

The Role of Founder Sir Stelios Haji-Ioannou

Central to any acquisition outcome is the stance of founder Sir Stelios Haji-Ioannou, who retains a 15% stake in the company. Market commentary indicates that the Haji-Ioannou family is unlikely to support a deal unless it offers a substantial premium above the current offer. Analysts note that while the board is publicly dismissing the bid, the shift in tone—inviting a 'more attractive' proposal—suggests the airline is testing the limit of Castlelake's valuation, which is rumored to be targeting a threshold of at least 700p per share, or approximately £5.3 billion.

Industry Trends in Private Equity

This move reflects a broader trend of private equity firms targeting European carriers. Investors are increasingly seeking to capitalize on share prices that have been suppressed by fuel cost volatility and geopolitical instability. Historically, similar ownership challenges have been managed through complex structures, such as those implemented during the 2015 acquisition of Aer Lingus by IAG, where national ownership trusts were utilized to maintain compliance with EU regulations. The case of Ryanair in 2021, which restricted UK shareholders' voting rights to remain majority EU-owned post-Brexit, further underscores the rigid enforcement of these ownership caps.

The PUSU Deadline and Next Steps

The July 5, 2026, deadline serves as the final decision point under the UK Takeover Code. By this date, Castlelake must either announce a firm intention to make an offer or formally walk away. The current process of sharing 'limited commercial information' is intended to bridge the valuation gap, though the board remains under pressure to balance immediate shareholder returns against the long-term strategic independence of the carrier.

Why This Matters for European Aviation

A successful acquisition would introduce a major private equity player into the heart of the European short-haul market. For stakeholders, the deal represents a potential inflection point for EasyJet’s valuation and competitive strategy. If Castlelake succeeds, the resulting ownership structure could set a precedent for how non-EU investors acquire and manage European low-cost carriers, potentially triggering a new wave of consolidation if the regulatory model proves successful.
