EnQuest PLC, 9 July 2021

General Meeting Notice Amendment

As a result of the successful completion of the Bookbuild for the Firm Placing and Placing announced on 30 June 2021 (the "Bookbuild Announcement"), EnQuest PLC ("EnQuest", or the "Company") confirms that the resolution to approve the proposed participation of Double A Limited in the potential Second Lien Financing (as defined in the Combined Circular and Prospectus of which the Notice convening the General Meeting forms part) is now withdrawn. The Company intended to rely on the Second Lien Financing in the event that the amount raised by the Capital Raising was less than $50 million. However, pursuant to the Firm Placing and Placing and Open Offer, a total of 190,122,384 New Ordinary Shares will be issued at the Offer Price of 19 pence per New Share (subject to certain conditions), raising gross proceeds of £36.1 million ($50 million) and therefore the Second Lien Financing is not required.

The withdrawal of resolution number 5 does not otherwise affect the validity of the Notice of the General Meeting, the proxy form or any proxy votes already submitted on other proposed resolutions. The numbering of all other proposed resolutions at the General Meeting will remain unchanged.

Defined terms in this announcement shall have the meaning given to them in the Bookbuild Announcement unless otherwise specified.

 Information to Distributors

Solely for the purposes of the product governance requirements contained within of Chapter 3 of the FCA Handbook Production Intervention and Product Governance Sourcebook (the "UK Product Governance Requirements"), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the UK Product Governance Requirements) may otherwise have with respect thereto, the New Ordinary Shares have been subject to a product approval process, which has determined that such securities are: (i) compatible with an end target market of investors who meet the criteria of retail investors and investors who meet the criteria of professional clients and eligible counterparties, each as defined in paragraph 3 of the FCA Handbook Conduct of Business Sourcebook; and (ii) eligible for distribution through all distribution channels (the "Target Market Assessment"). Notwithstanding the Target Market Assessment, distributors (for the purposes of UK Product Governance Requirements) should note that: (a) the price of the New Ordinary Shares may decline and investors could lose all or part of their investment; (b) the New Ordinary Shares offer no guaranteed income and no capital protection; and (c) an investment in the New Ordinary Shares is compatible only with investors who do not need a guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to be able to bear any losses that may result therefrom. The Target Market Assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the Capital Raising. Furthermore, it is noted that, notwithstanding the Target Market Assessment, J.P. Morgan Cazenove will only procure investors who meet the criteria of professional clients and eligible counterparties.

For the avoidance of doubt, the Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of Chapter 9A or 10A respectively of the FCA Handbook Conduct of Business Sourcebook; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other action whatsoever with respect to the New Ordinary Shares.

Each distributor is responsible for undertaking its own target market assessment in respect of the New Ordinary Shares and determining appropriate distribution channels.
