NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION IN WHOLE OR IN PART, IN, INTO OR FROM ANY JURISDICTION WHERE TO DO SO WOULD CONSTITUTE A VIOLATION OF THE RELEVANT LAWS OF SUCH JURISDICTION

[THIS ANNOUNCEMENT CONTAINS INSIDE INFORMATION]

This announcement is not an announcement of a firm intention to make an offer under Rule 2.7 of the City Code on Takeovers and Mergers (the “Code”). Accordingly, there can be no certainty that any such offer will be made.

Genel Energy plc ("Genel") notes the announcement made by DNO and confirms that it has received an unsolicited proposal from DNO (the "Proposal") regarding a possible offer to acquire the entire issued, and to be issued, ordinary share capital of Genel at a price of 69 pence in cash per Genel Share (the "Possible Offer").

The Board of Genel, having evaluated the Possible Offer together with its advisers, has unanimously rejected the Proposal, strongly believing that the Possible Offer fundamentally undervalues Genel. Genel shareholders are advised to take no action in response to the Possible Offer.

There can be no certainty that any offer will be made.

In accordance with Rule 2.6(a) of the Code, DNO shall, by no later than 5.00 pm on 4 September, either announce a firm intention to make an offer for Genel under Rule 2.7 of the Code or announce that it does not intend to make an offer for Genel, in which case the announcement will be treated as a statement to which Rule 2.8 of the Code applies. This deadline will only be extended with the consent of the Takeover Panel in accordance with Rule 2.6(c) of the Code.

On 2 July 2026, the boards of directors of Capricorn Energy plc ("Capricorn"), Genel and Genel Energy No.9 Limited ("Bidco") announced that they had reached agreement regarding the terms and conditions of a recommended cash offer by Bidco for Capricorn pursuant to which Bidco will acquire the entire issued and to be issued ordinary share capital of Capricorn (the "Genel Offer").  On 21 July 2026, Capricorn published a scheme document in relation to the Genel Offer, including notices of shareholder meetings to approve the Genel Offer, which have been convened for 18 August 2026.

This announcement is being made by Genel without the consent of DNO.

Enquiries:

The person responsible for arranging the release of this announcement on behalf of Genel is Luke Clements, Chief Financial Officer.

Linklaters LLP is retained as legal adviser to Genel.

Disclosure requirements of the Code

Under Rule 8.3(a) of the Code, any person who is interested in 1% or more of any class of relevant securities of an offeree company or of any securities exchange offeror (being any offeror other than an offeror in respect of which it has been announced that its offer is, or is likely to be, solely in cash) must make an Opening Position Disclosure following the commencement of the offer period and, if later, following the announcement in which any securities exchange offeror is first identified. An Opening Position Disclosure must contain details of the person’s interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror(s).

Relevant persons who deal in the relevant securities of the offeree company or of a securities exchange offeror prior to the deadline for making an Opening Position Disclosure must instead make a Dealing Disclosure.

Under Rule 8.3(b) of the Code, any person who is, or becomes, interested in 1% or more of any class of relevant securities of the offeree company or of any securities exchange offeror must make a Dealing Disclosure if the person deals in any relevant securities of the offeree company or of any securities exchange offeror. A Dealing Disclosure must contain details of the dealing concerned and of the person’s interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror(s), save to the extent that these details have previously been disclosed under Rule 8. A Dealing Disclosure by a person to whom Rule 8.3(b) applies must be made by no later than 3.30 pm (London time) on the business day following the date of the relevant dealing.

If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire or control an interest in relevant securities of an offeree company or a securities exchange offeror, they will be deemed to be a single person for the purpose of Rule 8.3.

Opening Position Disclosures must also be made by the offeree company and by any offeror and Dealing Disclosures must also be made by the offeree company, by any offeror and by any persons acting in concert with any of them (see Rules 8.1, 8.2 and 8.4).
