RECOMMENDED ACQUISITION

of

Serinus Energy plc

("Serinus" or the "Company")

by

Xtellus Capital Partners, Inc

("Xtellus")

to be effected by means of a scheme of arrangement under Article 125 of the

Companies (Jersey) Law 1991 (as amended)

Results of the Court Meeting and the General Meeting

On 24 March 2025, the Boards of Serinus and Xtellus announced that they had reached agreement on the terms of a recommended cash offer, pursuant to which Xtellus would acquire the entire issued and to be issued share capital of Serinus for 3.4 pence per share (the "Acquisition").

The Acquisition is to be effected by means of a scheme of arrangement under Article 125 of the

Companies (Jersey) Law 1991 (as amended) (the "Scheme"), full details of which were sent to the shareholders of Serinus in the circular dated 7 April 2025 (the "Scheme Document"). Capitalised terms in this announcement, unless otherwise defined herein, have the same meanings as set out in the Scheme Document.

Results of the Court Meeting and the General Meeting

Serinus is pleased to announce that, at the Court Meeting and General Meeting (together the "Meetings") each held earlier today, the requisite majorities of Serinus Shareholders present and voting (and entitled to vote) either in person or by proxy voted to approve the Scheme at the Court Meeting and the Special Resolution in connection with the implementation of the Scheme at the General Meeting.

The resolutions were therefore duly passed. Full details of the resolutions are set out in the notices of the Meetings contained in Parts VIII and IX of the Scheme Document, respectively.

The total number of Serinus Shares in issue at the Voting Record Time was 151,099,460. Serinus does not hold any Ordinary Shares in treasury. Therefore, the total voting rights in Serinus exercisable at general meetings of Serinus at the Voting Record Time were 151,099,460.

Voting Results of the Court Meeting

The Court Meeting sought approval from the holders of the Serinus Shares (other than the holders of Excluded Shares) for the Scheme. Each Serinus Shareholder, present in person or by proxy (not being a holder of the Excluded Shares), was entitled to vote one Serinus Share held at the Voting Record Time and voting was by way of a poll. There were 44,308,324 Excluded Shares as at the Voting Record Time, all being Serinus Shares registered in the name of or beneficially owned directly or indirectly by the Xtellus. Therefore, in total, 106,791,136 Serinus Shares could be voted at the Court Meeting.

Accordingly, the Court Meeting resolution proposed at the Court Meeting was duly passed.

Details of the votes cast were as follows:

· Note that the percentages in the table above are rounded to the nearest two decimal places.

· Where a Serinus Shareholder has cast some of their votes "for" and some of their votes "against" the resolution, such Serinus Shareholder has been counted as having voted both "for" and "against" the resolution for the purposes of determining the number of Serinus Shareholders who voted as set out in column 2 above. In this instance, 8 Serinus Shareholders voted both "for" and "against" and are therefore counted twice when calculating percentages, however, only 29 Serinus Shareholders voted in total.

· The Excluded Shares comprise any Serinus Shares registered in the name of, or beneficially owned by, Xtellus or any other member of the Wider Xtellus Group or their respective nominees.

· The references to Serinus Shares and Serinus Shareholders in the table above exclude the Excluded Shares and the Serinus Shareholders holding Excluded Shares.

Voting Results of the General Meeting

The General Meeting sought approval for the Resolution for the purpose of giving effect to the Scheme and associated amendments to the articles of association of the Company. Each Serinus Shareholder, present in person or by proxy, was entitled to vote one Serinus Share held at the Voting Record Time and voting was by way of a poll.

Accordingly, the Resolution was duly passed by the requisite majority.

Details of the votes cast were as follows:

Special Resolution

· Note that the percentages in the tables above are rounded to the nearest two decimal places.

· Proxy appointments which gave discretion to the Chairman have been included in the vote "For" totals.

· A vote withheld is not a vote in law and is not counted in the calculation of the proportion of votes 'For' or 'Against' the Resolution.

Next steps and timetable

The outcome of today's Meetings means that Conditions 2.1 and 2.2 (as set out in Part III of the Scheme Document) have been satisfied. The Acquisition remains subject to the satisfaction or (where applicable) waiver of the remaining Conditions as set out in Part III of the Scheme Document, including (amongst other things) the sanction of the Scheme by the Court at the Sanction Hearing, delivery of a copy of the Court Order to the Registrar of Companies and Romanian regulatory approval, which was filed on 16 April 2025.

The expected timetable of principal events for the implementation of the Scheme is as set out below. The dates are indicative only and are subject to change. The dates will depend, among other things, on the dates upon which: (i) the Conditions are satisfied or (if capable of waiver) waived; (ii) the Court sanctions the Scheme; and (iii) a copy of the Court Order is delivered to the Registrar of All dates and times are based on Serinus' and Xtellus' current expectations and are subject to change. If any of the dates and/or times in this expected timetable change materially, the revised dates and/or times will be notified to Serinus Shareholders a Regulatory Information Service and by making such announcement available on Serinus' website at https://serinusenergy.com/xtellus-rule-2-7-offer/.

Overseas Jurisdictions

The release, publication or distribution of this Announcement in, into or from jurisdictions other than Jersey, the United Kingdom, Canada or the United States may be restricted by law. Persons who are not resident in Jersey, the United Kingdom or Canada or who are subject to the laws of other jurisdictions should inform themselves of, and observe, any applicable requirements. Any failure to comply with the applicable 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. This Announcement has been prepared for the purposes of complying with Jersey law, Canadian securities laws and the Takeover Code 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 Jersey, the United Kingdom or Canada. This Announcement is not a prospectus, or a prospectus exempted document.

Unless otherwise determined by Xtellus or required by the Takeover Code, and permitted by applicable law and regulation, the Acquisition will not be made available, directly or indirectly, in, into or from a Restricted Jurisdiction or any other jurisdiction where to do so would violate the laws of that jurisdiction. Accordingly, copies of this Announcement will not be and must not be, mailed or otherwise forwarded, distributed or sent in, into or from any Restricted Jurisdiction or any jurisdiction where to do so would violate the laws of that jurisdiction, and persons receiving all documents relating to the Acquisition (including custodians, nominees and trustees) must not mail or otherwise forward, distribute or send them in or into or from any Restricted Jurisdiction or any other jurisdiction if to do so would constitute a violation of the laws of that jurisdiction.

The Acquisition shall be subject to the applicable requirements of the Takeover Code and the Panel and applicable Canadian securities laws that apply to Serinus due to its status as a "reporting issuer" in the provinces of Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Nova Scotia, Ontario, Prince Edward Island and Saskatchewan.

Further details in relation to overseas shareholders are contained in paragraph 16 of Part II (Explanatory Statement) of the Scheme Document.

Additional Information for US Investors

The Acquisition is being made to acquire the securities of a Jersey company by means of a members' scheme of arrangement provided for under Jersey Companies Law. Serinus is a "foreign private issuer" as defined under Rule 3b-4 under the US Exchange Act. A transaction effected by a foreign private issuer by means of a members' scheme of arrangement is not subject to the shareholder vote, proxy solicitation or tender offer rules under the US Exchange Act. Accordingly, the Scheme is subject to the disclosure requirements and practices applicable in Jersey to schemes of arrangement, which differ from the disclosure requirements of the US shareholder vote, proxy solicitation and tender offer rules and the US Securities Act.

Financial information included in this Announcement has been or will have been prepared in accordance with IFRS and may not therefore be comparable to financial information of US companies or companies whose financial statements are prepared in accordance with generally accepted accounting principles in the US.

Neither the SEC nor any state securities commission has reviewed, approved or disapproved this Announcement, the Scheme or any of the proposals described herein, or passed upon or determined the adequacy or accuracy of the information contained in this Announcement or disapproved or passed judgment upon the fairness or the merits of the Acquisition. Any representation to the contrary is a criminal offence in the United States.

The receipt of cash consideration by a US holder for the transfer of its Scheme Shares pursuant to the Scheme will likely be a taxable transaction for United States federal income tax purposes and under applicable United States state and local, as well as foreign and other, tax laws. In addition, Serinus Shareholders may be required to provide an applicable IRS Form W 8 or W 9 in order to prevent any backup withholding tax on the cash consideration. Each Serinus Shareholder is urged to consult his, her or their independent professional adviser immediately regarding the tax consequences of the Acquisition applicable to him, her or it, including under applicable United States state and local, as well as foreign and other, tax laws.

Serinus is formed under the laws of Jersey. In addition, some or all of its officers and directors reside outside the US, and some or all of its assets are or may be located in jurisdictions outside the US. Therefore, investors may have difficulty effecting service of process within the US upon those persons or recovering against Serinus or its officers or directors on judgments of US courts, including judgments based upon the civil liability provisions of US federal securities laws. Further, it may be difficult to compel a non US company and its affiliates to subject themselves to a US court's judgment. It may not be possible to sue Serinus or its officers or directors in a non US court for violations of US securities laws.

Additional Information for Canadian Investors

No securities commission or similar authority of Canada, or any other jurisdiction has reviewed or in any way passed upon this Announcement or the merits of the securities described herein, and any representation to the contrary is an offence under Canadian securities law.

The Acquisition relates to the shares of a Jersey company and is being made by means of a members' scheme of arrangement provided for under the Jersey Companies Law.

The receipt of cash consideration by a Canadian Holder for the transfer of its Serinus Shares pursuant to the Scheme will generally be a taxable transaction for Canadian federal income tax purposes and under applicable Canadian, as well as applicable foreign and other, tax laws. Each Serinus Shareholder is urged to consult his, her or their independent professional adviser immediately regarding the tax, and other, consequences of the Acquisition applicable to him, her or it, including under applicable Canadian local, as well as foreign and other, tax laws. Please see paragraph 16.2 of Part II (Explanatory Statement) the Scheme Document. Canadian Holders should review paragraph 15 of Part II (Explanatory Statement) entitled "Taxation" and paragraph 15.2 entitled "Canadian Federal Income Taxation".

Serinus is formed under the laws of Jersey. In addition, some or all of its officers and directors reside outside Canada, and some or all of its assets are or may be located in jurisdictions outside Canada. Therefore, investors may have difficulty effecting service of process within Canada upon those persons or recovering against Serinus or its officers or directors on judgments of Canadian courts, including judgments based upon the civil liability provisions of applicable Canadian securities laws. Further, it may be difficult to compel a non Canadian company and its affiliates to subject themselves to a Canadian court's judgment. It may not be possible to sue Serinus or its officers or directors in a non Canadian court for violations of applicable Canadian securities laws.

It is expected that Serinus (which is currently a "reporting issuer" in the provinces of Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Nova Scotia, Ontario, Prince Edward Island and Saskatchewan) will cease to be a reporting issuer under Canadian securities laws shortly after completion of the Acquisition, subject to fulfilling the applicable conditions under such laws.

Additional Information for Polish Investors

The Acquisition is being made to acquire the securities of a Jersey company by means of a members' scheme of arrangement provided for under Jersey Companies Law. A transaction effected by means of a members' scheme of arrangement differs from the tender offer rules (including the minimum price calculation) under the Polish Act on Public Offering, the Scheme is subject to the disclosure requirements and practices applicable in Jersey to schemes of arrangement, which differ from the disclosure requirements of the relevant Polish tender offer rules.

None of the securities referred to in this Announcement have been approved or disapproved by the PFSC or any other Polish regulatory authority. The PFSC has not reviewed, approved or disapproved this Announcement, the Scheme or any of the proposals described herein, or passed upon or determined the adequacy or accuracy of the information contained in this Announcement or disapproved or passed judgment upon the fairness or the merits of the Acquisition.

The receipt of cash consideration by a Polish holder for the transfer of its Scheme Shares pursuant to the Scheme will likely be a taxable transaction for Polish income or capital gains tax purposes. Each Serinus Shareholder is urged to consult his, her or their independent professional adviser immediately regarding the tax consequences of the Acquisition applicable to him, her or it, including under applicable Polish as well as foreign and other, tax laws.

Serinus is formed under the laws of Jersey. In addition, some or all of its officers and directors reside outside Poland, and some or all of its assets are or may be located in jurisdictions outside Poland. Therefore, investors may have difficulty effecting service of process within Poland upon those persons or recovering against Serinus or its officers or directors on judgments of Polish courts, including judgments based upon the civil liability provisions of Polish laws. Further, it may be difficult to compel a non Polish company and its affiliates to subject themselves to a Polish court's judgment. It may not be possible to sue Serinus or its officers or directors in a non Polish court for violations of Polish securities laws.

Forward-looking Statements

This Announcement (including information incorporated by reference in this Announcement), oral statements made regarding the Acquisition, and other information published by Xtellus and Serinus contain statements which are, or may be deemed to be, "forward-looking statements". Forward-looking statements are prospective in nature and are not based on historical facts, but rather on current expectations and projections of the management of Xtellus and Serinus about future events, and are therefore subject to risks and uncertainties which could cause actual results to differ materially from the future results expressed or implied by the forward-looking statements.

The forward-looking statements contained in this Announcement include statements relating to the expected effects of the Acquisition on Xtellus and Serinus (including their future prospects, developments and strategies), the expected timing and scope of the Acquisition and other statements other than historical facts. Often, but not always, forward-looking statements can be identified by the use of forward-looking words such as "prepares", "plans", "expects" or "does not expect", "is expected", "is subject to", "budget", "projects", "synergy", "strategy", "scheduled", "goal", "estimates", "forecasts", "cost saving", "intends", "anticipates" or "does not anticipate", or "believes", or variations of such words and phrases or statements that certain actions, events or results "may", "could", "should", "would", "might" or "will" be taken, occur or be achieved. 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 Xtellus' and Serinus', any member of the Xtellus Group or any member of the Serinus Group's, operations and potential synergies resulting from the Acquisition; and (iii) the effects of global economic conditions and governmental regulation on Xtellus' and Serinus', any member of the Xtellus Group or any member of the Serinus Group's, business.

Although Xtellus and Serinus believe that the expectations reflected in such forward-looking statements are reasonable, Xtellus and Serinus can give no assurance that such expectations will prove to be correct. By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend on circumstances that will occur in the future. There are a number of factors that could cause actual results and developments to differ materially from those expressed or implied by such forward-looking statements.

These factors include, but are not limited to: the ability to complete the Acquisition; the ability to obtain shareholder approvals and the satisfaction of other Conditions on the proposed terms and schedule; changes in the global political, economic, business and competitive environments and in market and regulatory forces; changes in future exchange and interest rates; changes in tax rates; future business combinations or disposals; changes in general economic and business conditions; changes in the behaviour of other market participants; changes in the anticipated benefits from the proposed transaction not being realised as a result of changes in general economic and market conditions in the countries in which Xtellus and Serinus operate; weak, volatile or illiquid capital and/or credit markets; changes in tax rates, interest rate and currency value fluctuations, the degree of competition in the geographic and business areas in which Xtellus and Serinus operate; and changes in laws or in supervisory expectations or requirements. Other unknown or unpredictable factors could cause actual results to differ materially from those expected, estimated or projected in the forward-looking statements. If any one or more of these risks or uncertainties materialises or if any one or more of the assumptions proves 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 Xtellus nor Serinus, 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 will actually occur. You are cautioned not to place any reliance on these forward-looking statements.

Specifically, statements of estimated cost savings and synergies related 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. 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 Xtellus Group or the Serinus Group, or any of their respective associates, directors, officers, employees or advisers, are expressly qualified in their entirety by the cautionary statement above.

Other than in accordance with their legal or regulatory obligations, neither Xtellus nor Serinus is under any obligation, and Xtellus and Serinus expressly disclaim any intention or obligation, to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.
