INCREASED RECOMMENDED CASH ACQUISITION

of

Capricorn Energy plc (“Capricorn”)
by

Genel Energy No.9 Limited (“Bidco”)
(a company indirectly owned by Genel Energy plc (“Genel”))

to be effected by means of a Court-sanctioned scheme of arrangement
under Part 26 of the Companies Act 2006

PUBLICATION AND POSTING OF SUPPLEMENTARY LETTER

Further to the announcement made on 25 September 2026 regarding an increased offer from Bidco to acquire the entire issued and to be issued share capital of Capricorn (the "Increased Genel Offer"), Capricorn announces that a letter providing an update as to the status of the Acquisition (the "Supplementary Letter") is today being posted or made available by Capricorn to Capricorn Shareholders and, for information only, to holders of awards under the Capricorn Share Plans and persons with information rights.

Capricorn has confirmed that it is not required by the Court of Session to convene any further shareholder meetings in connection with the Acquisition. Accordingly, Capricorn Shareholders are not required to take any voting action in respect of the Increased Genel Offer.

The Supplementary Letter will be made available (subject to any applicable restrictions relating to persons in, or resident in, Restricted Jurisdictions) for inspection free of charge on Capricorn's website at https://www.capricornenergy.com/investors/ and on Bidco's website at https://genelenergy.com/offer/ no later than 12 noon on the Business Day following this announcement and will be available up to and including the end of the Offer Period. The contents of these websites are not incorporated into, and do not form part of, this announcement.

A copy of the Supplementary Letter has been submitted to the National Storage Mechanism and will shortly be available for inspection at: https://data.fca.org.uk/#/nsm/nationalstoragemechanism.

Capitalised terms used in this announcement shall, unless otherwise defined, have the same meanings as set out in the scheme document published by Capricorn on 21 July 2026 in connection with Genel’s offer (the "Scheme Document").

Expected timetable of principal events

An expected timetable of principal events for the Scheme is set out in the Scheme Document. As previously announced by Genel and Bidco, the Egyptian Merger Condition has been satisfied, leaving the Egyptian Condition as the only outstanding regulatory condition. Significant progress has already been made towards satisfying the Egyptian Condition and Capricorn (in co-operation with Genel and Bidco) continues to engage in constructive discussions with the Egyptian Government.

Genel and Bidco continue to expect that the Egyptian Condition will be satisfied in such time as to enable the Scheme to become Effective during the fourth quarter of 2026. Capricorn will make further announcements as appropriate with such announcements being available on Capricorn's website at https://www.capricornenergy.com/investors/ and on Bidco's website at https://genelenergy.com/offer/.

DNO Offer Meetings

Although the DNO Offer has not lapsed, in light of the Increased Genel Offer, the Capricorn Directors intend to adjourn the court meeting and the general meeting in connection with the DNO Offer convened for 1.00 p.m. and 1.15 p.m., respectively, on 16 October 2026 indefinitely. A further announcement will be made by Capricorn in this regard in due course. The Capricorn Board continues to recommend that Capricorn Shareholders take no further action in relation to the DNO Offer.

Further information

This announcement is for information purposes only and is not intended to and does not constitute, or form part of, an offer to sell or an invitation to purchase any securities or the solicitation of an offer to buy, otherwise acquire, subscribe for, sell or otherwise dispose of any securities, pursuant to the Acquisition or otherwise, nor shall there be any purchase, sale, issuance or exchange of securities or such solicitation in any jurisdiction in which such offer, invitation, solicitation, purchase, sale, issuance or exchange is unlawful.

The Acquisition is made solely by means of the Scheme Document which, together with the Supplementary Letter and the Forms of Proxy, contains the full terms and conditions of the Acquisition, including details of how to vote in respect of the resolutions proposed in connection with the Acquisition. Any vote, approval, decision in respect of, or other response to, the Acquisition should be made only on the basis of the information contained in the Scheme Document.

The statements contained in this announcement are made as at the date of this announcement, unless some other time is specified in relation to them, and the release of this announcement shall not give rise to any implication that there has been no change in the facts set out in this announcement since such date.

This announcement has been prepared for the purpose of complying with English law, Scots law, the Code, the Market Abuse Regulation and the Disclosure Guidance and Transparency Rules, and the information disclosed may not be the same as that which would have been disclosed if this announcement had been prepared in accordance with the laws of jurisdictions outside England and Wales, and Scotland. The Acquisition will be subject to the applicable requirements of the Code, the Panel, the London Stock Exchange and the Financial Conduct Authority.

This announcement and the Supplementary Letter do not constitute a prospectus or prospectus exempted document.

Overseas Shareholders

The release, publication or distribution of this announcement, the Supplementary Letter and the accompanying documents in or into certain jurisdictions other than the United Kingdom may be restricted by the laws and/or regulations of those jurisdictions. Persons into whose possession this announcement, the Supplementary Letter and the accompanying documents come who are not resident in the United Kingdom or who are subject to the laws and/or regulations of any jurisdiction other than the United Kingdom should inform themselves of, and observe, any such applicable laws and/or regulations in their jurisdiction. In particular, the ability of persons who are not resident in the United Kingdom to vote their Capricorn Shares with respect to the Scheme at the Court Meeting or the resolution(s) at the General Meeting, or to appoint another person as proxy to vote at the Court Meeting or the General Meeting on their behalf, may be affected by the laws of the relevant jurisdiction in which they are located. Further details in relation to Overseas Shareholders are contained in the Scheme Document. Any failure to comply with any such restrictions may constitute a violation of the securities laws of any such jurisdiction. To the fullest extent permitted by applicable law, the companies and persons involved in the Acquisition disclaim any responsibility or liability for the violation of such restrictions by any person.

Unless otherwise determined by Capricorn or required by the Takeover Code, and permitted by applicable law and regulation, the Acquisition shall not be made available, directly or indirectly, in, into or from a Restricted Jurisdiction where to do so would violate the laws in that jurisdiction and no person may vote in favour of the Acquisition by any such use, means, instrumentality or form within a Restricted Jurisdiction or any other jurisdiction if to do so would constitute a violation of the laws of that jurisdiction. Accordingly, copies of this announcement, the Supplementary Letter and all documents relating to the Acquisition are not being, and must not be, directly or indirectly, mailed or otherwise forwarded, distributed or sent in, into or from a Restricted Jurisdiction where to do so would violate the laws in that jurisdiction, and persons receiving this announcement, the Supplementary Letter and all documents relating to the Acquisition (including custodians, nominees and trustees) must not mail or otherwise distribute or send them in, into or from such jurisdictions where to do so would violate the laws in that jurisdiction.

The availability of the Acquisition to Capricorn Shareholders who are not resident in the United Kingdom may be affected by the laws of the relevant jurisdictions in which they are resident. Persons who are not resident in the United Kingdom should inform themselves of, and observe, any applicable requirements.

The Acquisition shall be subject to the applicable requirements of the Code, the Panel, the London Stock Exchange and the Financial Conduct Authority.

Additional information for U.S. investors

The Acquisition relates to shares of a Scottish company listed on the Official List of the London Stock Exchange and is proposed to be effected by means of a scheme of arrangement under Part 26 of the Companies Act 2006 which will be governed by Scots law. A transaction effected by means of a scheme of arrangement is not subject to the tender offer rules or the proxy solicitation rules under the US Exchange Act.

Accordingly, the Acquisition is subject to the disclosure and procedural requirements applicable in the United Kingdom to schemes of arrangement which differ from the disclosure and procedural requirements of United States tender offer and proxy solicitation rules.

However, if in the future Bidco were to elect to implement the Acquisition by means of a takeover offer, such takeover offer would be made in compliance with all applicable United States laws and regulations, including, without limitation, to the extent applicable and subject to any applicable exemptions, Section 14(e) of the US Exchange Act and Regulation 14E thereunder. Such a takeover would be made in the United States by Bidco and no one else.

In accordance with normal United Kingdom practice, Bidco or its nominees, or its brokers (acting as agents), may from time to time make certain purchases of, or arrangements to purchase, shares or other securities of Capricorn outside the US, other than pursuant to the Acquisition, until the date on which the Acquisition and/or the Scheme becomes Effective, lapses or is otherwise withdrawn. These purchases may occur either in the open market at prevailing prices or in private transactions at negotiated prices. Any information about such purchases or arrangements to purchase shall be disclosed as required in the UK, shall be reported to a Regulatory Information Service and shall be available on the London Stock Exchange website atwww.londonstockexchange.com.

The receipt of consideration by a US holder for the transfer of its Capricorn Shares pursuant to the Scheme shall be a taxable transaction for United States federal income tax purposes. Each Capricorn Shareholder is urged to consult their independent professional adviser immediately regarding the tax consequences of the Acquisition applicable to them, including under applicable United States federal, state and local, as well as overseas and other, tax laws.

Financial information relating to Capricorn included in this announcement and the Supplementary Letter has been or shall have been prepared in accordance with accounting standards applicable in the United Kingdom and may not be comparable to financial information of US companies or companies whose financial statements are prepared in accordance with generally accepted accounting principles in the United States ("US GAAP"). US GAAP differs in certain significant respects from accounting standards applicable in the United Kingdom. None of the financial information in this announcement has been audited in accordance with auditing standards generally accepted in the United States or the auditing standards of the Public Company Accounting Oversight Board (United States).

Bidco is organised under the laws of England and Wales and Capricorn is organised under Scots law. Some or all of the officers and directors of Bidco and Capricorn, respectively, are residents of countries other than the United States. In addition, most of the assets of Bidco and Capricorn are located outside the United States. As a result, it may be difficult for US shareholders of Capricorn to effect service of process within the United States upon Bidco or Capricorn or their respective officers or directors or to enforce against them a judgment of a US court predicated upon the federal or state securities laws of the United States, including judgments based upon the civil liability provisions of the US federal securities laws. US holders of Capricorn Shares may not be able to sue a non-US company or its officers or directors in a non-US court for violations of US securities laws. Further, it may be difficult to compel a non-US company and its affiliates to subject themselves to a US court's jurisdiction or judgment.

Forward-looking statements

This announcement, the Supplementary Letter (including information incorporated by reference in this announcement or the Supplementary Letter), oral statements made regarding the Acquisition, and other information published by Capricorn, Bidco or any member of the Genel Group contain statements which are, or may be deemed to be, “forward-looking statements”. Such forward-looking statements are prospective in nature and are not based on historical facts, but rather on current expectations and on numerous assumptions regarding the business strategies and the environment in which Genel, any member of the Genel Group or the Enlarged Group shall operate in the future and are subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied by those statements.

The forward-looking statements contained in this announcement or the Supplementary Letter relate to Genel, any member of the Genel Group or the Enlarged Group’s future prospects, developments and business strategies, the expected timing and scope of the Acquisition and other statements other than historical facts. In some cases, these forward-looking statements can be identified by the use of forward-looking terminology, including the terms “believes”, “estimates”, “will look to”, “would look to”, “plans”, “prepares”, “anticipates”, “expects”, “is expected to”, “is subject to”, “budget”, “scheduled”, “forecasts”, “synergy”, “strategy”, “goal”, “cost-saving”, “projects”, “intends”, “may”, “will”, “shall” or “should” or their negatives or other variations or comparable terminology. Forward-looking statements may include statements relating to the following: (i) future capital expenditures, expenses, revenues, earnings, synergies, economic performance, indebtedness, financial condition, dividend policy, losses and future prospects; (ii) business and management strategies and the expansion and growth of Genel’s, any member of the Genel Group’s or Capricorn’s operations and potential synergies resulting from the Acquisition; and (iii) the effects of global economic conditions and governmental regulation on Genel’s, any member of the Genel Group’s or Capricorn’s business.

By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend on circumstances that shall occur in the future. These events and circumstances include changes in the global, political, economic, business, competitive, market and regulatory forces, future exchange and interest rates, changes in tax rates, future business combinations or disposals, and any epidemic, pandemic or disease outbreak. If any one or more of these risks or uncertainties materialises or if any one or more of the assumptions prove incorrect, actual results may differ materially from those expected, estimated or projected. Such forward-looking statements should therefore be construed in the light of such factors.

Neither Capricorn, Bidco nor any of Genel or any member of the Genel Group, nor any of their respective associates or directors, officers or advisers, provides any representation, assurance or guarantee that the occurrence of the events expressed or implied in any forward-looking statements in this announcement or the Supplementary Letter shall actually occur. Given these risks and uncertainties, potential investors should not place any reliance on forward-looking statements.

Specifically, statements of estimated cost savings and synergies relate to future actions and circumstances which, by their nature, involve risks, uncertainties and contingencies. As a result, the cost savings and synergies referred to may not be achieved, may be achieved later or sooner than estimated, or those achieved could be materially different from those estimated. Due to the scale of the Enlarged Group, there may be additional changes to the Enlarged Group’s operations. As a result, and given the fact that the changes relate to the future, the resulting cost synergies may be materially greater or less than those estimated.

The forward-looking statements speak only at the date of this announcement. All subsequent oral or written forward-looking statements attributable to any member of the Genel Group or Capricorn Group, or any of their respective associates, directors, officers, employees or advisers, are expressly qualified in their entirety by the cautionary statement above.

Capricorn, the Genel Group and Bidco expressly disclaim any obligation to update such statements other than as required by law or by the rules of any competent regulatory authority, whether as a result of new information, future events or otherwise.

No profit forecasts, profit estimates or quantified financial benefit statement

Nothing in this announcement or the Supplementary Letter is intended, or is to be construed, as a profit forecast or estimate for any period and no statement in this announcement or the Supplementary Letter should be interpreted to mean that earnings or earnings per share for Bidco or Capricorn, as appropriate, for the current or future financial years would necessarily match or exceed the historical published earnings or earnings per share for Bidco or Capricorn, as appropriate.

Disclosure requirements of the Code

Under Rule 8.3(a) of the Code, any person who is interested in 1 per cent. 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). An Opening Position Disclosure by a person to whom Rule 8.3(a) applies must be made by no later than 3.30 p.m. on the tenth business day following the commencement of the offer period and, if appropriate, by no later than 3.30 p.m. on the tenth business day following the announcement in which any securities exchange offeror is first identified. 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 per cent. 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 p.m. (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).

Details of the offeree and offeror companies in respect of whose relevant securities Opening Position Disclosures and Dealing Disclosures must be made can be found in the Disclosure Table on the Panel’s website at http://www.thetakeoverpanel.org.uk, including details of the number of relevant securities in issue, when the Offer Period commenced and when any offeror was first identified. You should contact the Panel’s Market Surveillance Unit on [phone] if you are in any doubt as to whether you are required to make an Opening Position Disclosure or a Dealing Disclosure.

Rounding

Certain figures included in this announcement have been subjected to rounding adjustments. Accordingly, figures shown for the same category presented in different tables may vary slightly and figures shown as totals in certain tables may not be an arithmetic aggregation of the figures that precede them.
