Full year 2022 results revised date; expected results and 2023 guidance unchanged

EnQuest PLC ('EnQuest' or 'the Group') today announces a revised date for the publication of its preliminary financial results for the year ended 31 December 2022. Changes in the UK Energy Profits Levy have impacted the preparation and subsequent audit of the Group's financial statements.

As a result, the Group will now announce its results on 5 April 2023, meaning a delay to the previously planned release date of 23 March 2023.

The Board confirms that the 2022 financial results and 2023 guidance are expected to be in line with those provided in the trading update provided on 17 February 2023.
