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

FOR IMMEDIATE RELEASE

13 August 2026

RECOMMENDED INCREASED ACQUISITION

of

Pharos Energy plc ("Pharos")

by

Ratio Petroleum Energy LP ("Ratio")

to be effected by means of a scheme of arrangement

under Part 26 of the Companies Act 2006

TERMINATION OF SERICA OFFER

UPDATE REGARDING SHAREHOLDER MEETINGS TO APPROVE INCREASED RATIO OFFER

1.   Introduction

On 24 June 2026, the board of directors of each of Ratio and Pharos announced that they had reached agreement on the terms of a recommended acquisition by Ratio of the entire issued and to be issued share capital of Pharos (the "Original Acquisition"). Under the terms of the Original Acquisition, Pharos Shareholders were entitled to receive a total value of up to 28.0 pence in cash per Pharos Share, comprising 23.0683 pence in cash per Pharos Share together with 4.0 pence in cash per Pharos Share by way of a special dividend and the FY25 Final Dividend (as defined below).

The scheme document in respect of the Acquisition (the "Scheme Document") was published and made available to Pharos Shareholders on 21 July 2026. This announcement should be read in conjunction with the Scheme Document.

Following the announcement of a competing offer for Pharos by Serica Energy plc ("Serica") on 26 July 2026 (the "Serica Offer"), the board of directors of each of Ratio and Pharos announced on 7 August 2026 that they have agreed the terms of an increased recommended all-cash offer by Ratio for the entire issued and to be issued share capital of Pharos (the "Increased Ratio Offer") (the "Increased Ratio Offer Announcement") to be effected by means of a Court-sanctioned scheme of arrangement under Part 26 of the Companies Act 2006 (the "Acquisition").

Under the terms of the Acquisition, as revised by the Increased Ratio Offer, Pharos Shareholders will be entitled to receive:

•     28.8183 pence in cash per Pharos Share (the "Cash Consideration"); plus

•     4.0 pence in cash per Pharos Share by way of special dividend to be paid from Pharos' existing cash resources that the Pharos Board intends to declare prior to completion of the Acquisition with the record and payment dates aligned with the corresponding dates for determining entitlements to, and payment of, the Cash Consideration due to Pharos Shareholders under the terms of the Acquisition (the "Special Dividend"),

which would result in a total value of 32.8183 pence per Pharos Share. Pharos Shareholders, where they qualified, will continue to be entitled to retain the final dividend of 0.9317 pence in cash per Pharos Share for the financial year ended 31 December 2025 which was declared on 25 March 2026 and paid on 17 July 2026 to qualifying Pharos Shareholders on the register at close of business on 12 June 2026 (the "FY25 Final Dividend").

Accordingly, taking together the total value offered of 32.8183 pence per Pharos Share with the FY25 Final Dividend, the aggregate amount Pharos Shareholders will receive pursuant to the Acquisition, as revised by the Increased Ratio Offer, is 33.75 pence per Pharos Share.

Subsequently, Serica announced on 10 August 2026 that the financial terms of the Serica Offer are final and will not be increased or improved.

2.   Termination of Serica Offer

As noted in the Increased Ratio Offer Announcement, the Pharos Directors have withdrawn their recommendation of the Serica Offer and have determined not to proceed with the scheme of arrangement to implement the Serica Offer or to convene any Pharos Shareholder meeting for the purposes of considering the Serica Offer.  In addition, Serica has formally notified the Pharos Directors that it does not intend to implement the Serica Offer as a Takeover Offer as defined in Chapter 3 of Part 28 of the Companies Act.

Accordingly, and on the basis that the financial terms of the Serica Offer are final and will not be increased or improved, the Pharos board has provided its consent to the Panel on Takeovers and Mergers (the "Panel") to release Serica from its obligation under Rule 2.7(b) and Rule 24.1 of the City Code on Takeovers and Mergers (the "Code") to proceed with the Serica Offer and Serica has confirmed that it will not proceed with the Serica Offer.

As a result, the Panel has confirmed to Pharos and Serica that:

•     Serica is released from its obligation under Rule 2.7(b) and Rule 24.1 of the Code to proceed with the Serica Offer; and

•     Serica is subject to the restrictions set out in Rule 35.1 of the Code and is prohibited from, amongst other things, making any offer for Pharos without the consent of the Panel for a period of 12 months.

Capitalised terms used and not defined in this announcement have the meanings given to them in the Scheme Document.

This announcement has been made with the consent of Serica.

3.   Irrevocable Undertakings

As noted in the Increased Ratio Offer Announcement, Ratio has received irrevocable undertakings from each of the Pharos Directors who hold Pharos Shares to vote in favour of the Scheme at the Court Meeting and the resolutions to be proposed at the General Meeting (or, in the event that the Acquisition is implemented by way of a Takeover Offer, to accept or procure acceptance of the Takeover Offer), in respect of a total of 2,380,289 Pharos Shares, representing approximately 0.57 per cent. of the existing issued ordinary share capital of Pharos on the business day prior to the release of the Increased Ratio Offer Announcement (the "Latest Practicable Date").

Ratio has also received irrevocable undertakings to vote in favour of the Scheme at the Court Meeting and the resolutions to be proposed at the General Meeting (or, in the event that the Acquisition is implemented by way of a Takeover Offer, to accept or procure acceptance of the Takeover Offer) from Pharos Shareholders in respect of a total of 171,470,348 Pharos Shares representing, in aggregate, approximately 41.19 per cent. of Pharos' existing issued ordinary share capital on the Latest Practicable Date. As a result of the Increased Ratio Offer, all of these irrevocable undertakings will now continue to be binding in accordance with their terms and are no longer capable of lapsing under paragraph 7.1.4. or 7.1.5 of the relevant undertakings (as applicable) in the event of a higher competing offer from any third party.

Ratio has therefore received irrevocable undertakings in respect of a total of 173,850,637 Pharos Shares representing, in aggregate, approximately 41.76 per cent. of Pharos' existing issued ordinary share capital in issue on the Latest Practicable Date.

4.   Update regarding Shareholder Meetings in relation to the Increased Ratio Offer

As noted in the Increased Ratio Offer Announcement, the Pharos Board intends to adjourn the Court Meeting and General Meeting (together, the "Shareholder Meetings") which have been convened for 17 August 2026 to provide Pharos Shareholders with more time to make informed voting decisions.

It is intended that the Court Meeting and General Meeting to consider the Acquisition, the notices of which are set out at Parts 9 and 10 of the Scheme Document, will be adjourned to:

·      Court Meeting: 28 August 2026 at 11:00 a.m.

·      General Meeting: 28 August 2026 at 11:15 a.m.

The Court Meeting and the General Meeting are to be held at the offices of Ashurst Perkins Coie UK LLP, London Fruit & Wool Exchange, 1 Duval Square, London E1 6PW. Pharos will make a further announcement in due course once the Meetings have been formally adjourned to the date and times noted above.

5.   Action required

As further described in the Scheme Document, before the Court is asked to sanction the Scheme and in order for the Scheme to become Effective, the Scheme will require: (i) the approval of a majority in number representing 75 per cent. or more in value of votes cast by Scheme Shareholders present and voting either in person or by proxy at the Court Meeting (or any adjournment thereof), which has been convened by an order of the Court; and (ii) the passing of the Resolution by the requisite majority of Pharos Shareholders at the General Meeting (or any adjournment thereof). The Scheme is also subject to the satisfaction or (where applicable) waiver of the Conditions and further terms that are set out in the Scheme Document, including the Regulatory Conditions in Egypt and Vietnam.

It is important that, for the Court Meeting in particular, as many votes as possible are cast (whether in person or by proxy) in order for the Court to be satisfied that there is a fair and reasonable representation of Scheme Shareholders' opinion. Scheme Shareholders and Pharos Shareholders are therefore strongly urged to complete, sign and return their Forms of Proxy or to appoint a proxy electronically either through the relevant share portal service, Proxymity or through CREST as soon as possible and, in any event, by no later than 11:00 a.m. on 26 August 2026 in respect of the Court Meeting and 11:15 a.m. on 26 August 2026 in respect of the General Meeting in accordance with the instructions set out in the Scheme Document and the Forms of Proxy. Instructions in relation to voting and the completion of the Forms of Proxy are included in the Scheme Document. Scheme Shareholders and Pharos Shareholders are also strongly encouraged to appoint the Chair of the meeting as their proxy.

6.   Expected timetable of principal events

An updated expected timetable of principal events for the Scheme is set out in the appendix to this announcement. Pharos will make further announcements as appropriate with such announcements being available on Pharos' website at https://www.pharos.energy/investors/offer-by-ratio-petroleum/ and on Ratio's website at https://ratiopetroleum.com/offer-disclaimer/.

The updated expected timetable includes a revised Long Stop Date such that the Acquisition will be conditional upon the Scheme becoming unconditional and becoming Effective, subject to the provisions of the Code, by no later than 11.59 p.m. on 15 July 2027, or such later date: (i) as may be agreed in writing by Ratio and Pharos (with the Panel's consent, if required); or (ii) (in a competitive situation) as may be specified by Ratio with the consent of the Panel; or (iii) as the Panel may direct under the Note on Section 3 of Appendix 7 of the Code, and, in each case, as the Court may approve (if such approval is required).

7.   Pharos Directors' recommendation of the Increased Ratio Offer

The Pharos Directors, who have been so advised by Rothschild & Co as to the financial terms of the Increased Ratio Offer, consider the terms of the Increased Ratio Offer to be fair and reasonable. In providing its advice to the Pharos Directors, Rothschild & Co has taken into account the commercial assessments of the Pharos Directors. Rothschild & Co is providing independent financial advice to the Pharos Directors for the purposes of Rule 3 of the Code.

Accordingly, the Pharos Directors unanimously recommend that Pharos Shareholders vote in favour of the Scheme at the Court Meeting and the resolution to be proposed at the General Meeting as the Pharos Directors who hold Pharos Shares have irrevocably undertaken to do in respect of their own beneficial holdings of 2,380,289 Pharos Shares representing, in aggregate, approximately 0.57 per cent. of the ordinary share capital of Pharos.

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 (or, if the Acquisition is implemented by way of a Takeover Offer, the Offer document) which, together with 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, 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. 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 Scheme Document do not constitute a prospectus or prospectus exempted document.

Overseas Shareholders

The release, publication or distribution of this announcement, the Scheme Document 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 Scheme Document 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 Pharos 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 Ratio or required by the 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 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 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. If the Acquisition is implemented by a Takeover Offer (unless otherwise permitted by applicable law or regulation), the Takeover Offer may not be made, directly or indirectly, in or into or by use of the mails or any other means or instrumentality (including, without limitation, facsimile, email or other electronic transmission, telex or telephone) of interstate or foreign commerce of, or any facility of a national state or other securities exchange, of any Restricted Jurisdiction and the Takeover Offer will not be capable of acceptance by any such use, means, instrumentality or facilities or from or within any Restricted Jurisdiction.

The availability of the Acquisition to Pharos 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.

Additional information for U.S. investors

Pharos Shareholders resident in the United States should note that the Acquisition relates to the shares of an English company and is being made by means of a scheme of arrangement provided for under, and governed by, the law of England and Wales. 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 Securities Exchange Act of 1934, as amended (the "US Exchange Act"). Accordingly, the Acquisition is subject to the disclosure and procedural requirements and practices 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. If, in the future, Ratio exercises the right to implement the Acquisition by way of a Takeover Offer and determines to extend the Takeover Offer into the United States, the Acquisition will be made in compliance with applicable United States laws and regulations, including (to the extent applicable and subject to any applicable exemptions) Section 14(e) of the US Exchange Act and Regulation 14E thereunder. Any such Takeover Offer would be made in the United States by Ratio and no one else.

Financial information included in this announcement and the Scheme Document has been prepared in accordance with accounting standards under UK-adopted international accounting standards and in accordance with International Financial Reporting Standards ("IFRS") and thus 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).

The receipt of cash pursuant to the Acquisition by a US holder of Pharos Shares as consideration for the transfer of its Scheme Shares pursuant to the Scheme may be a taxable transaction for US federal income tax purposes and under applicable US state and local, as well as foreign and other, tax laws. Each Pharos Shareholder is therefore urged to consult with independent legal, tax and financial advisers in connection with making a decision regarding the Acquisition.

Ratio and Pharos are each organised and located in a non-US jurisdiction and some or all of their officers and directors may be residents of a non-US jurisdiction. In addition, most or all of the assets of Ratio and Pharos are located outside the United States. It may therefore be difficult for holders of Pharos Shares located in the United States to effect service of process within the United States upon Ratio or Pharos or to enforce their rights and any claim arising out of US securities law. It may not be possible to sue Ratio and Pharos (or their officers and directors) in a non-US court for violations of US securities laws. Furthermore, it may be difficult to compel Ratio or Pharos and their respective affiliates to subject themselves to the jurisdiction or judgment of a US court.

In accordance with normal UK practice and to the extent permitted under Rule 14e-5(b) of the US Exchange Act (if applicable), Ratio, certain affiliated companies and their nominees or brokers (acting as agents), may from time to time make certain purchases of, or arrangements to purchase, Pharos Shares outside of the United States, other than pursuant to the Acquisition, until the date on which the Acquisition and/or Scheme becomes effective, lapses or is otherwise withdrawn. If such purchases or arrangements to purchase were to be made they would occur either in the open market at prevailing prices or in private transactions at negotiated prices and comply with applicable law, including English law, the Code and the US Exchange Act. Any information about such purchases will be disclosed as required in the UK, will be reported to the Regulatory News Service of the London Stock Exchange and will be available on the London Stock Exchange website at https://www.londonstockexchange.com/.

Neither the US Securities and Exchange Commission nor any securities commission of any state of the United States has approved or disapproved the Acquisition, passed judgement upon the fairness of the Acquisition, or passed judgement upon the adequacy or accuracy of this announcement. Any representation to the contrary is a criminal offence in the United States.

Forward-looking statements

The information provided in this announcement and the Scheme Document contains certain forward-looking statements and information (collectively, "forward-looking statements") within the meaning of applicable securities laws. Such forward-looking statements include, without limitation, forecasts, estimates, expectations and objectives for future operations that are subject to assumptions, risks and uncertainties, many of which are beyond the control of Ratio or Pharos. Forward-looking statements are predictive in nature, depend upon or refer to future events or conditions, or include words such as "expect", "plan", "anticipate", "believe", "intend", "maintain", "continue to", "pursue", "design", "result in", "sustain" "estimate", "potential", "growth", "near-term", "long-term", "forecast", "contingent" and similar expressions, or are events or conditions that "will", "would", "may", "could" or "should" occur or be achieved. The forward-looking statements contained in this announcement speak only as of the date hereof and are expressly qualified by this cautionary statement.

In addition, information and statements relating to reserves are by their nature forward-looking statements, as they involve the implied assessment, based on certain estimates and assumptions, that the reserves described exist in the quantities predicted or estimated, and can be profitably produced in the future. The recovery and reserve estimates of Pharos' reserves provided herein are estimates only, and there is no guarantee that the estimated reserves will be recovered. Consequently, actual results may differ materially from those anticipated in the forward-looking statements.

Forward-looking statements are based upon, among other things, factors, expectations and assumptions that Ratio and Pharos have made as at the date of this announcement regarding, among other things: the satisfaction of the conditions to closing of the Acquisition in a timely manner, if at all, including the receipt of all necessary approvals; and that the Acquisition will comply with all applicable requirements of the Code, the Panel, the London Stock Exchange and the Financial Conduct Authority.

Undue reliance should not be placed on the forward-looking statements because no assurance can be given that they will prove to be correct. Since forward-looking statements address future events and conditions, by their very nature they involve inherent risks and uncertainties. These risks include, but are not limited to: the completion and timing of the Acquisition; the ability of Ratio and Pharos to receive, in a timely manner, the necessary regulatory, Court, shareholder, stock exchange and other third-party approvals and to satisfy the other conditions to closing of the Acquisition; the ability of the parties to complete the Acquisition on the terms contemplated by Ratio and Pharos or at all; consequences of not completing the Acquisition, including the volatility of the share prices of Ratio and Pharos, negative reactions from the investment community, and the required payment of certain costs related to the termination of the Acquisition; and the focus of management's time and attention on the Acquisition and other disruptions arising from the Acquisition.

Except as may be required by applicable securities laws, neither Ratio nor Pharos assume any obligation or intent to update publicly or revise any forward-looking statements made herein, 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 Scheme Document is intended, or is to be construed, as a profit forecast or estimate for any period and no statement in this announcement or the Scheme Document should be interpreted to mean that earnings or earnings per share for Ratio or Pharos, as appropriate, for the current or future financial years would necessarily match or exceed the historical published earnings or earnings per share for Ratio or Pharos, 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.
