On a Sunday of a holiday weekend, easyJet’s board agreed in principle to sell one of Europe’s defining budget airlines. US investment firm Castlelake’s latest offer — its fifth — is £6.90 per share in cash, valuing the carrier at £5.2 billion in equity and up to £5.5 billion (about $7.3 billion) fully diluted. That’s a 73% premium to where the shares closed on May 29, the day Castlelake first disclosed its interest to UK regulators.
“In principle” is doing real work in that sentence. The board says the new price is one it would be “minded to recommend” to shareholders — a sharp turn from the “highly opportunistic” label it hung on the earlier approaches. Under the UK’s takeover rules, Castlelake now has until August 3 to put up a firm offer or walk away. Until that filing lands, this is a handshake, not a deal.
The buyer matters as much as the price. Castlelake is not a generalist fund wandering into aviation — it’s an aviation-finance specialist that has spent two decades buying, leasing, and financing aircraft. It is, in effect, the smart money in planes deciding that a whole airline — fleet, network, slots — is cheaper to buy than the public market realizes, even after a European equity rally that just pushed the Stoxx to 52-week highs.
The catch: Brussels owns the rulebook
EU regulations require airlines flying intra-EU routes to be majority owned and controlled by EU nationals. Castlelake’s answer is structural: it would hold 49% of the bidding vehicle, with the remaining 51% held by two EU nationals. Regulators won’t just count the cap table — they’ll probe who actually controls the airline. Similar structures have survived scrutiny before, but this one would be tested at a scale that invites attention, and it’s the single most plausible way the deal dies.
The 73% premium isn’t generosity — it’s a measurement. It’s the size of the gap between what public markets will pay for a European airline and what aviation insiders think the assets are worth. Public investors priced easyJet on fuel bills, strikes, and quarterly noise; Castlelake is pricing the fleet, the Gatwick slots, and a decade of cash flows. If this structure clears Brussels, every European carrier trading below asset value just became a target — and boards across the sector lose their favorite excuse for a cheap share price. The era of private capital outbidding public patience keeps finding new aisles to shop.
What to watch
- August 3. The Takeover Code deadline: firm offer or walk. Watch for the financing details when the formal filing lands.
- The control test. How the 49/51 ownership vehicle is documented — and whether EU regulators open a formal review of who really steers the airline.
- Monday’s tape. European airline shares will reprice takeover odds across the sector, with the discount-carrier cohort in focus — against a backdrop where OPEC+ just set August’s oil supply, the other variable that runs airline math.
