Nasdaq Stockholm delisting update

As notified in a previous announcement on 5 September 2023, EnQuest PLC ('EnQuest' or the 'Company') plans to apply for a delisting of the Company's shares from Nasdaq Stockholm. The formal request to delist is therefore expected to be submitted to Nasdaq Stockholm on 5 December with the last day of trading likely to be around two weeks after the application date (the "Delisting Date"). The Company's shares will remain listed on the London Stock Exchange.

In order to continue trading in EnQuest shares, EnQuest shareholders holding their shares through Euroclear Sweden AB must arrange for a cross-border transfer of their shares into the book-entry system maintained by Euroclear UK & Ireland Limited (also known as CREST).

DNB Markets, a part of DNB Bank ASA, Sweden Branch ('DNB Markets') acts as EnQuest's Issuing Agent and will coordinate the conversion process. Shareholders should in the first instance, however, discuss the cross-border transfer of shares with their respective nominee bank.

Cross-border transfer applications should be made within the period of action, defined as being 31 October to 13 December 2023, and transfers made through DNB will be completed free of any charges to individual shareholders and nominees. Shareholders that do not apply for the cross-border transfer within the period of action will not be able to trade in the Company's shares following the Delisting Date.

• A letter with cross-border instructions will be distributed to all directly registered shareholders and to all custodians by 1 November 2023.
• The instruction letter explains the cross-border process and any actions to be taken by shareholders.
• Cross-border settlement will be done on a weekly basis starting from 8 November until 13 December

Shareholders should contact their respective nominee banks or EnQuest's Issuing Agent, DNB Markets (email: emissioner@dnb.se phone: +4684734550), for more information.

The information was submitted for publication, through the agency of the contact persons set out below, at 14:00 UK time on 30 October 2023.
