Citadel's Total easyJet Position Rises to 5.043994% via Cash-Settled Swaps

The notification reveals that Citadel's exposure is held predominantly through financial instruments rather than direct share ownership. Of the 5.043994% total, only 0.000026% represents voting rights directly attached to shares — equivalent to 200 shares held in easyJet (ISIN: GB00B7KR2P84). The remaining 5.043968% is held through cash-settled swaps classified under DTR5.3.1R.(1)(b), covering 38,233,786 voting rights. Cash-settled swaps carry economic exposure without conferring direct voting control, a structure commonly used by institutional investors and hedge funds to build significant positions in listed companies.

Kenneth C. Griffin Named as Ultimate Controlling Person Across Citadel's Chain of Entities

The TR-1 form identifies Kenneth C. Griffin as the ultimate controlling natural person behind the notification. The chain of controlled undertakings through which the instruments are effectively held includes Citadel GP LLC, Citadel Advisors Holdings LP, Citadel Advisors LLC, and Citadel Multi-Asset Master Fund Ltd., all registered in Delaware, United States. The disclosure was completed in London on 9 November 2026, four days after the threshold-crossing date of 5 November 2026, in accordance with the UK's Disclosure and Transparency Rules governing the timely reporting of major holdings in UK-listed issuers.

Proxy Voting Rights in easyJet Assigned to Institutional Shareholder Services

The announcement also discloses that proxy voting rights over the 200 directly held shares — representing 0.000026% of voting rights — have been assigned to Institutional Shareholder Services Inc. (ISS), with no expiry date stated. This arrangement is a standard practice among large institutional investors that delegate governance-related voting decisions to specialist proxy advisers. The existence of this proxy arrangement does not alter the overall size of Citadel's economic exposure to easyJet, which remains defined by the cash-settled swap position forming the vast majority of the group's total disclosed interest.

easyJet's Position as a Major European Low-Cost Carrier Attracts Institutional Interest

easyJet operates as one of Europe's largest short-haul, low-cost airlines, with routes spanning the UK and continental Europe. The airline's revenue model centres on seat sales, ancillary fees, and its easyJet Holidays division. Institutional investors tracking European aviation recovery, cost discipline, and consumer travel demand may view positions in easyJet as a proxy for broader sector dynamics. The crossing of Citadel's holding above the 5% disclosure threshold is a regulatory milestone that requires public notification and flags a substantial increase in one of the airline's major disclosed derivative-based positions.
