Shareholders
Shareholders of Chrysaor Holdings Limited
Chrysaor Holdings Limited is incorporated in the Cayman Islands (registration number MC-197161) and registered with UK Companies House as an overseas company (FC027988). As a Cayman Islands private company limited by shares, its shareholder register is not filed with UK Companies House, and Cayman Islands company law does not require shareholder information to be made public. Companies House’s persons-with-significant-control (PSC) register for FC027988 records no PSC statements; the UK PSC filing regime primarily applies to UK-incorporated companies rather than overseas companies registered only in respect of a UK establishment. No current shareholder register or ownership percentage for Chrysaor Holdings Limited could be verified from a public UK source as of 24 September 2026.
Reputable public reporting indicates that funds managed by EIG Global Energy Partners provided substantial financial backing to Chrysaor Holdings Limited from 2014 and became a major shareholder, and that in 2021 Chrysaor combined with Premier Oil plc via a reverse takeover to form the London Stock Exchange-listed Harbour Energy plc. These sources describe historical financing and transaction context rather than a filed, current shareholder register, and no verified present-day percentage shareholding in Chrysaor Holdings Limited could be confirmed.
Data availability
Not public: Cayman Islands company law does not require disclosure of the shareholder register, and Chrysaor Holdings Limited’s status as an overseas company means it falls outside the UK PSC filing regime that applies to UK-incorporated companies; no verified shareholder or UBO information is publicly available as of 24 September 2026.

Group Structure
Group structure of Chrysaor Holdings Limited
Chrysaor Holdings Limited (FC027988) is a Cayman Islands-incorporated private company registered in the UK as an overseas company. Companies House does not publish a filed parent/subsidiary register for overseas companies, and no persons-with-significant-control statement is recorded for this entity, so no current immediate or ultimate parent, and no subsidiary, can be verified from a UK statutory filing as of 24 September 2026.
Reputable public reporting, including Harbour Energy plc’s own corporate history page, describes a historical corporate affiliation: Harbour Energy (then a private, EIG Global Energy Partners-backed company) acquired Chrysaor Holdings Limited in 2017 and used it as the vehicle to purchase a package of UK North Sea oil and gas assets from Royal Dutch Shell for approximately US$3.0 billion. In 2021, Chrysaor combined with Premier Oil plc through a reverse takeover; the resulting company, Companies House number SC234781, was renamed from Premier Oil plc to Harbour Energy plc on 31 March 2021 and is listed on the London Stock Exchange under ticker HBR. These sources establish a historical affiliation between Chrysaor Holdings Limited and the Harbour Energy group but do not constitute a filed confirmation of a current immediate parent or ownership percentage for Chrysaor Holdings Limited.
