SOUTHERN ENERGY ANNOUNCES AMENDED TERMS OFPREVIOUSLY ANNOUNCED FINANCINGS 

Calgary, Alberta - 25 March 2025 - Southern Energy Corp. ("Southern" or the "Company") (TSXV:SOU, AIM:SOUC) announces that it has agreed to amend the terms of its previously announced equity fundraise to raise aggregate gross proceeds of approximately US$6.0 million (approximately £4.8 million / C$8.5 million) of units of the Company ("Units"), as follows: (i) to reduce the price from 4.3 pence to 3.8 pence (the "Placing Price") or from C$0.08 to C$0.07 per Unit (the "Prospectus Price"); (ii) to increase the amount of Warrants per Unit from one half of one Common Share purchase Warrant to one whole Warrant per Unit; and (iii) to reduce the exercise price of such Warrants from 5.3 pence to 4.8 pence (in the case of the Placing) or from C$0.10 to C$0.09 per Common Share (in the case of the Prospectus Offering).

The remainder of the terms of the fundraising, which consists of a placing of new Units to new and existing institutional investors on AIM (the "Placing") and a concurrent public offering of new Units in Canada (the "Prospectus Offering" and, together with the Placing, the "Fundraising"), will continue without further amendment, other than the revision to the expected timetable for the Fundraising, as further detailed below.

Research Capital Corporation ("RCC") is acting as sole agent and sole bookrunner (the "Agent") in connection with the Prospectus Offering. Tennyson Securities, a trading name of Shard Capital Partners LLP ("Tennyson Securities") and Hannam & Partners, a trading name of H&P Advisory Limited ("H&P") are acting as joint bookrunners (the "Joint Bookrunners") in connection with the Placing.

Overview of the Fundraising

· Southern intends to conduct an approximate US$6.0 million equity fundraise to accelerate the completion of its three drilled and uncompleted ("DUC") wells, drilled as part of its Q1 2023 drilling campaign on its Gwinville acreage, as well as fully funding (alongside cashflow) the drilling of two vertical Cotton Valley wells on its Mechanicsburg acreage;

· The net proceeds from the Fundraising are expected to fully fund, alongside existing cash, cash flows and undrawn debt facilities, the completion of the Gwinville DUCs at a cost of approximately US$2.5 million per well and the drilling of the Mechanicsburg wells at a cost of approximately US$3.5 million;

· The Company is seeking the approval of the holders of its outstanding convertible unsecured subordinated debentures (the "Debentures"), by way of obtaining extraordinary resolutions of greater than 66.67% of the aggregate principal amount of the Debentures, to amend the terms of the indenture governing the Debentures such that, subject to and concurrent with the completion of the Fundraising, an amount equal to 102.5% of the principal amount outstanding under the Debentures plus all accrued and unpaid interest as of the closing date would convert into Units at the revised Prospectus Price (the "Debenture Amendment"). The completion of the Debenture Amendment and the issuance of the Units upon the conversion of the Debentures remain subject to acceptance of the TSXV. The Units to be issued pursuant to the Debenture Amendment will be subject to customary lock up provisions.

​

Summary on Fundraising

o  A Placing of new Units (the "Placing Units") to new and existing institutional investors at the Placing Price. The Placing will be conducted through an accelerated bookbuild process (the "Bookbuild") which will launch immediately following the release of this Announcement. The Placing is subject to the terms and conditions set out in the Appendix to this Announcement (which forms part of this announcement);

o  A concurrent Prospectus Offering of new Units (the "Prospectus Units") on a best efforts agency basis at the Prospectus Price. The Prospectus Offering will be conducted pursuant to the terms and conditions of an amended agency agreement to be entered into between the Company and the Agent. The size of the Prospectus Offering will be determined in the context of the market at the time of entering into the amended agency agreement between the Company and the Agent; and

o  Certain directors and members of senior management of the Company forming part of a president's list are expected to subscribe into the Fundraising alongside investors. 

· The Prospectus Offering is being conducted pursuant to the Company's Canadian base shelf prospectus dated 28 November 2024 (the "Base Shelf Prospectus"). An amended and restated prospectus supplement amending and restating the prospectus supplement dated 14 March 2025 (as amended, the "Prospectus Supplement") relating to the Prospectus Offering will be filed in each of the provinces of Canada, other than Quebec. Copies of the Prospectus Supplement and accompanying Base Shelf Prospectus, when available, can be obtained free of charge under the Company's profile on SEDAR+ at www.sedarplus.ca. Delivery of the Base Shelf Prospectus and the Prospectus Supplement and any amendments thereto will be satisfied in accordance with the "access equals delivery" provisions of applicable Canadian securities legislation, such that the Company intends to file the Prospectus Supplement within two business days. The Base Shelf Prospectus and the Prospectus Supplement will contain important detailed information about the Company and the Prospectus Financing. Prospective investors should read the Prospectus Supplement and accompanying Base Shelf Prospectus and the other documents the Company has filed on SEDAR+ at www.sedarplus.ca before making an investment decision. The Prospectus Offering is expected to close on or around 31 March 2025, and is conditional on the Company obtaining the extraordinary resolutions in connection with the Debenture Amendment, and subject customary closing conditions, including the approval of the TSX Venture Exchange (the "TSXV"). The Company will use commercially reasonable efforts to obtain the necessary approvals to list the Warrants issuable pursuant to the Prospectus Offering.

· The number of Placing Units and Prospectus Units (and the underlying Common Shares and Warrants) to be issued will be determined by the Company following completion of the Bookbuild in consultation with the Joint Bookrunners and RCC.

Solely for the purposes of the product governance requirements contained within the FCA Handbook Product Intervention and Product Governance Sourcebook (the "UK Product Governance Rules"), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the UK Product Governance Rules) may otherwise have with respect thereto, the Placing Shares and Warrants have been subject to a product approval process, which has determined that the Placing Shares and Warrants are: (i) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties, each defined in the FCA Handbook Conduct of Business Sourcebook ("COBS"); and (ii) eligible for distribution through all distribution channels as are permitted by the UK Product Governance Rules (the "UK Target Market Assessment").

Solely for the purposes of the product governance requirements contained within: (a) EU Directive 2014/65/EU on markets in financial instruments, as amended ("MiFID II"); (b) Articles 9 and 10 of Commission Delegated Directive (EU) 2017/593 supplementing MiFID II; and (c) local implementing measures (together, the "MiFID II Product Governance Requirements"), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" and/or "distributor" (for the purposes of the MiFID II Product Governance Requirements) may otherwise have with respect thereto, the Placing Shares and Warrants have been subject to a product approval process, which has determined that the Placing Shares and Warrants are: (i) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties (each as defined in MiFID II); and (ii) eligible for distribution through all distribution channels as are permitted by MiFID II (the "EU Target Market Assessment").

Notwithstanding the UK Target Market Assessment and the EU Target Market Assessment, distributors should note that: the price of the Common Shares may decline and investors could lose all or part of their investment; the Common Shares offer no guaranteed income and no capital protection; and an investment in the Common 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.

Each of the UK Target Market Assessment and the EU Target Market Assessment is without prejudice to any contractual, legal or regulatory selling restrictions in relation to the Placing.

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

Persons (including, without limitation, nominees and trustees) who have a contractual or other legal obligation to forward a copy of this Announcement (or any part of it) should seek appropriate advice before taking any action.

These terms and conditions apply to persons making an offer to acquire Placing Shares and Warrants. Each Placee hereby agrees with the Joint Bookrunners and the Company to be bound by these terms and conditions as being the terms and conditions upon which Placing Shares will be issued or acquired and Warrants granted. A Placee shall, without limitation, become so bound if a Bookrunner confirms to such Placee its allocation of Placing Shares and Warrants.

Upon being notified of its allocation of Placing Shares and Warrants, a Placee shall be contractually committed to acquire the number of Placing Shares allocated to it at the Placing Price and Warrants and, to the fullest extent permitted by law, will be deemed to have agreed not to exercise any rights to rescind or terminate or otherwise withdraw from such commitment.

Details of the Placing Agreement and the Placing Shares

The Joint Bookrunners and the Company have entered into a Placing Agreement, under which the Joint Bookrunners have, on the terms and subject to the conditions set out therein, undertaken to use their reasonable endeavours to procure subscribers for Placing Shares at the Placing Price. The Placing is not being underwritten by either of the Joint Bookrunners or any other person. For every one Placing Share subscribed for, the Placee will also be granted one Warrant. Each Warrant will entitle the Placee to subscribe for one Common Share at a price of 4.8 pence per Common Share for a period of 36 months. The Warrants will be unlisted and no application will be made for the Warrants to be admitted to trading on AIM or any other stock exchange.

The number of Placing Shares and Warrants will be determined following completion of the Bookbuild. The timing of the closing of the Bookbuild, the number of Placing Shares and Warrants and their allocations are at the discretion of the Joint Bookrunners, following consultation with the Company. Allocations will be confirmed orally or by email by the relevant Bookrunner following the close of the Bookbuild. An announcement confirming these details will then be made by the Company as soon as practicable following completion of the Bookbuild.

The Placing Shares will, when issued, be subject to the Articles, will be credited as fully paid and non-assessable and rank equally in all respects with the existing Common Shares (and the new Common Shares to be issued pursuant to the Prospectus Offering), including the right to receive all dividends and other distributions (if any) declared, made or paid on or in respect of Common Shares after the date of issue of the Placing Shares.

Subject to Admission, the Placing Shares will trade on AIM under the trading symbol "SOUC" and with ISIN CA8428133059.

Application for admission to trading

Application will be made to: (a) the London Stock Exchange plc for admission of the Placing Shares and the Prospectus Shares to trading on AIM; and (b) the TSXV for listing of the Placing Shares and the Prospectus Shares for trading on the facilities of the TSXV. It is expected that settlement of any such shares (via Depositary Interests) and Admission will become effective at 8.00 a.m. on or around 2 April 2025 and that dealings in the Placing Shares and Prospectus Shares will commence at that time.

Bookbuild

The Joint Bookrunners are conducting a bookbuilding process to determine demand for participation in the Placing by potential Placees at the Placing Price. This Appendix gives details of the terms and conditions of, and the mechanics of participation in, the Placing. No commissions will be paid to Placees or by Placees in respect of any Placing Shares or Warrants.

The Joint Bookrunners and the Company shall be entitled to effect the Placing by such alternative method to the Bookbuild as they may, in their sole discretion, determine.

4. In order to participate in the Placing, prospective Placees should communicate their bid by telephone or email to their usual contact at the relevant Bookrunner. Each bid should state the number of Placing Shares and Warrants which the prospective Placee wishes to subscribe for or purchase at the Placing Price. Bids may be scaled down by the relevant Bookrunner on the basis referred to in paragraph 8 below.

5. The timing of the closing of the Bookbuild will be at the discretion of the Joint Bookrunners. The Company reserves the right to reduce or seek to increase the amount to be raised pursuant to the Placing, in its absolute discretion.

6. Allocations of the Placing Shares and Warrants will be determined by the Joint Bookrunners, following consultation with the Company. Each Placee's allocation will be confirmed to Placees orally, or by email, by the relevant Bookrunner following the close of the Bookbuild and a trade confirmation or contract note will be dispatched as soon as possible thereafter. Oral or emailed confirmation from the relevant Bookrunner will give rise to an irrevocable, legally binding commitment by that person (who at that point becomes a Placee), in favour of that Bookrunner and the Company, under which it agrees to acquire by subscription the number of Placing Shares at the Placing Price and Warrants allocated to it and otherwise on the terms and subject to the conditions set out in these Terms and Conditions and in accordance with the Articles. Except with the relevant Bookrunner's consent, such commitment will not be capable of variation or revocation.

7. The Company will make an announcement following the close of the Bookbuild detailing the number of Placing Shares to be issued at the Placing Price and Warrants to be granted to Placees.

8. Subject to paragraphs 4 and 5 above, the relevant Bookrunner may choose not to accept bids and/or to accept bids, either in whole or in part, on the basis of allocations determined at its discretion (after consultation with the Company) and may scale down any bids for this purpose on such basis as it may determine. The Joint Bookrunners may also, notwithstanding paragraphs 4 and 5 above, subject to the prior consent of the Company, allocate Placing Shares and Warrants after the time of any initial allocation to any person submitting a bid after that time.

9. A bid in the Bookbuild will be made on the terms and subject to the conditions in this Announcement (including these Terms and Conditions) and will be legally binding on the Placee on behalf of which it is

made and except with the relevant Bookrunner's consent will not be capable of variation or revocation from the time at which it is submitted.

10. Irrespective of the time at which a Placee's allocation pursuant to the Placing is confirmed, settlement for all Placing Shares to be acquired pursuant to the Placing will be required to be made at the same time, on the basis explained below under "Registration and Settlement".

11. All obligations of the Joint Bookrunners under the Placing will be subject to fulfilment of the conditions referred to below "Conditions of the Placing" and to the Placing not being terminated on the basis referred to below under "Right to terminate under the Placing Agreement".

12. By participating in the Placing, each Placee agrees that its rights and obligations in respect of the Placing will terminate only in the circumstances described below and will not be capable of rescission or termination by the Placee.

13. To the fullest extent permissible by law and the applicable rules of the Financial Conduct Authority, neither of the Joint Bookrunners, nor any of their respective affiliates, agents, directors, officers or employees shall have any liability to Placees (or to any other person whether acting on behalf of a Placee or otherwise whether or not a recipient of these terms and conditions) in respect of the Placing. In particular, neither of the Joint Bookrunners, nor any of their respective affiliates, agents, directors, officers or employees shall have any liability (including to the extent permissible by law, any fiduciary duties) in respect of the Joint Bookrunners' conduct of the Placing or of such alternative method of effecting the Placing as the Joint Bookrunners and the Company may determine.

Conditions of the Placing

The Placing is conditional upon the Placing Agreement becoming unconditional and not having been terminated in accordance with its terms. Each of the Joint Bookrunners' obligations under the Placing Agreement in respect of the Placing Shares and Warrants are conditional on, inter alia:

3. the Minimum Gross Proceeds being raised (which, for the avoidance of doubt, may be raised in entirety through any of the Placing or Prospectus Offering);

4. receipt by the Company of the TSXV approval;

9. the Placing Agreement not having been terminated by the Joint Bookrunners in accordance with its terms.

If: (i) any of the conditions contained in the Placing Agreement, including those described above, are not fulfilled or (where applicable) waived by the Joint Bookrunners by the respective time or date where specified (or such later time or date as the Joint Bookrunners may notify to the Company, being not later than the Long Stop Date);

(ii) any of such conditions becomes incapable of being fulfilled; or (iii) the Placing Agreement is terminated in the

circumstances specified below, the Placing will not proceed and the Placees' rights and obligations hereunder in relation to the Placing Shares and Warrants shall cease and terminate at such time and each Placee agrees that no claim can be made by the Placee in respect thereof.

The Joint Bookrunners may, at their discretion and upon such terms as they thinks fit, waive, or extend the period for (subject to the Long Stop Date), compliance by the Company with the whole or any part of any of the Company's obligations in relation to the conditions in the Placing Agreement save that the condition relating to Admission taking place may not be waived. Any such extension or waiver will not affect Placees' commitments as set out in these Terms and Conditions.

Neither the Joint Bookrunners, the Company nor any of their respective affiliates, agents, directors, officers or employees shall have any liability to any Placee (or to any other person whether acting on behalf of a Placee or otherwise) in respect of any decision they may make as to whether or not to waive or to extend the time and/or date for the satisfaction of any condition to the Placing nor for any decision they may make as to the satisfaction of any condition or in respect of the Placing generally and, by participating in the Placing, each Placee agrees that any such decision is within the absolute discretion of the Joint Bookrunners.

Right to terminate the Placing Agreement

The Joint Bookrunners are entitled, at any time before Admission, to terminate the Placing Agreement by giving notice to the Company in certain circumstances, including, inter alia, if before Admission:

1. any of the warranties given in the Placing Agreement are not true and accurate and not misleading when given at the date of the Placing Agreement or would not be true and accurate or would be misleading if they were repeated on Admission;

2. the Company has failed to comply with its obligations under the Placing Agreement, or with the requirements of any applicable laws or regulations (including MAR, the AIM Rules, the TSXV Rules and Canadian Securities Laws) in relation to the Placing;

3. any of the conditions set out in the Placing Agreement are not fulfilled or (if capable of waiver) waived by the Joint Bookrunners or shall have become incapable of being fulfilled by the respective time(s) and date(s) (if any) specified in the Placing Agreement;

4. there has been any development or event which will or is likely to have a material adverse effect on the condition (financial, operational, legal or otherwise), prospects, solvency, liquidity, management, results of operations, financial position, business or general affairs of the Group taken as a whole, whether or not foreseeable and whether or not arising in the ordinary course of business; or

5. there has been a change in national or international financial, political, economic, monetary or stock market conditions (primary or secondary) or an imposition of or compliance with any law or governmental or regulatory order, rule, regulation, restriction or direction,

which, in the opinion of the Joint Bookrunners, would or would be likely to prejudice materially the Company or render the Placing (or any material part thereof) or Admission impractical or inadvisable.

The rights and obligations of the Placees will not be subject to termination by the Placees or any prospective Placees at any time or in any circumstances. By participating in the Placing, Placees agree that the exercise by the Joint Bookrunners of any right of termination or other discretion under the Placing Agreement shall be within the absolute discretion of the Joint Bookrunners and that the Joint Bookrunners need not make any reference to Placees in this regard and that neither the Joint Bookrunners nor any of their respective affiliates shall have any liability to Placees whatsoever in connection with any such exercise or failure so to exercise.

No Admission Document or Prospectus

The Placing Shares and Warrants are being offered to a limited number of specifically invited persons only and have not been nor will be offered in such a way as to require the publication of a prospectus in the United Kingdom. No offering document, admission document or prospectus has been or will be submitted to be approved by the FCA or the London Stock Exchange in relation to the Placing, and Placees' commitments will be made solely on the basis of the information contained in these Terms and Conditions and the business and financial information that the Company is required to publish in accordance with the AIM Rules and the TSXV Rules, including this Announcement (the "Exchange Information"). Neither the Base Prospectus nor the Company's Prospectus Supplement is a prospectus for the purposes of Section 85(1) of FSMA and, accordingly, will not be examined or approved as a prospectus by the FCA under Section 87A FSMA or by the London Stock Exchange and it will not be filed with the FCA pursuant to the FCA's Prospectus Regulation Rules nor will it be approved by a person authorised under FSMA, for the purposes of Section 21 FSMA. Each Placee, by accepting a participation in the Placing, agrees that the content of the Exchange Information (including this Announcement) is exclusively the responsibility of the Company and confirms that it has not relied on any other information, representation, warranty, or statement made by or on behalf of the Company, the Joint Bookrunners (or either Bookrunner) or any other person and neither of the Joint Bookrunners, the Company nor any other person will be liable for any Placee's decision to participate in the Placing based on any other information, representation, warranty or statement which the Placees may have obtained or received and, if given or made, such information, representation, warranty or statement must not be relied upon as having been authorised by the Joint Bookrunners (or either of them), the Company or their respective officers, directors, employees or agents. Each Placee acknowledges and agrees that it has relied on its own investigation of the business, financial or other position of the Company in accepting a participation in the Placing. Neither the Company nor the Joint Bookrunners are making any undertaking or warranty to any Placee regarding the legality of an investment in the Placing Shares and Warrants by such Placee under any legal, investment or similar laws or regulations. Each Placee should not consider any information in this Announcement to be legal, tax or business advice. Each Placee should consult its own solicitor, tax adviser and financial adviser for independent legal, tax and financial advice regarding an investment in the Placing Shares and Warrants. Nothing in this paragraph shall exclude the liability of any person for fraudulent misrepresentation.

Registration and Settlement

Following the close of the Bookbuild, each Placee allocated Placing Shares in the Placing will be sent a trade confirmation or contract note in accordance with the standing arrangements in place with the relevant Bookrunner, stating the number of Placing Shares allocated to it at the Placing Price, the aggregate amount owed by such Placee (in pounds sterling) and a form of confirmation in relation to settlement instructions.

Each Placee will be deemed to agree that it will do all things necessary to ensure that delivery and payment is completed as directed by the relevant Bookrunner in accordance with the standing CREST settlement instructions which they have in place with that Bookrunner.

Settlement of transactions in the Placing Shares via the Depositary Interests (ISIN: CA8428133059) following Admission will take place within the system administered by Euroclear UK & International Limited ("CREST") provided that, subject to certain exceptions, each Joint Bookrunner reserves the right to require settlement for, and delivery of, the Placing Shares (or a portion thereof) to Placees by such other means that it deems necessary if delivery or settlement is not possible or practicable within CREST within the timetable set out in these Terms and Conditions or would not be consistent with the regulatory requirements in any Placee's jurisdiction.

It is expected that settlement will take place on 2 April 2025 in accordance with the instructions set out in the contract note.

Interest is chargeable daily on payments not received from Placees on the due date in accordance with the arrangements set out above at the rate of 4 percentage points above the prevailing LIBOR rate as determined by the relevant Bookrunner.

Each Placee is deemed to agree that, if it does not comply with these obligations, the relevant Bookrunner may sell any or all of the Placing Shares and Warrants allocated to that Placee on such Placee's behalf and retain from the proceeds, for that Bookrunner's account and benefit (as agent for the Company), an amount equal to the aggregate amount owed by the Placee plus any interest due. The relevant Placee will, however, remain liable and shall indemnify the relevant Bookrunner on demand for any shortfall below the aggregate amount owed by it and may be required to bear any stamp duty or stamp duty reserve tax or securities transfer tax (together with any interest or penalties) which may arise upon the sale of such Placing Shares and Warrants on such Placee's behalf. By communicating a bid for Placing Shares, each Placee confers on the relevant Bookrunner such authorities and powers necessary to carry out any such sale and agrees to ratify and confirm all actions which that Bookrunner lawfully takes in pursuance of such sale. Legal and/or beneficial title in and to any Placing Shares and Warrants shall not pass to the relevant Placee until it has fully complied with its obligations hereunder.

If Placing Shares are to be delivered to a custodian or settlement agent, Placees should ensure that the form of confirmation is copied and delivered immediately to the relevant person within that organisation.

Insofar as Placing Shares or Warrants are registered in a Placee's name or that of its nominee or in the name of any person for whom a Placee is contracting as agent or that of a nominee for such person, such Placing Shares and Warrants should, subject as provided below, be so registered free from any liability to UK stamp duty or stamp duty reserve tax or securities transfer tax. Neither of the Joint Bookrunners nor the Company will be liable in any circumstances for the payment of stamp duty, stamp duty reserve tax or securities transfer tax in connection with any of the Placing Shares and Warrants. Placees will not be entitled to receive any fee or commission in connection with the Placing.

The provisions of these Terms and Conditions may be waived, varied or modified as regards specific Placees or on a general basis by the relevant Bookrunner.

The agreement to settle a Placee's subscription and/or purchase (and/or the subscription of a person for whom such Placee is contracting as agent) free of stamp duty and stamp duty reserve tax depends on the settlement relating only to a subscription by it and/or such person direct from the Company for the Placing Shares (via Depositary Interests) in question. Such agreement assumes that the Placing Shares are not being subscribed for in connection with arrangements to issue depositary receipts or to transfer the Placing Shares into a clearance service. If there are any such arrangements, or the settlement relates to any other subsequent dealing in the Placing Shares, stamp duty or stamp duty reserve tax may be payable, for which neither the Company or the Joint Bookrunners will be responsible, and the Placee to whom (or on behalf of whom, or in respect of the person for whom it is participating in the Placing as an agent or nominee) the allocation, allotment, issue or delivery of Placing Shares has given rise to such UK stamp duty or stamp duty reserve tax undertakes to pay such UK stamp duty or stamp duty reserve tax forthwith and to indemnify on an after-tax basis and to hold harmless the Company and the Joint Bookrunners in the event that any of the Company and/or the Joint Bookrunners have incurred any such liability to UK stamp duty or stamp duty reserve tax. If this is the case, each Placee should seek its own advice and notify the relevant Bookrunner accordingly.

In addition, Placees should note that they will be liable for any stamp duty and all other stamp, issue, securities, transfer, registration, documentary or other duties or taxes (including any interest, fines or penalties relating thereto) payable outside the UK by them or any other person on the subscription or purchase by them of any Placing Shares and Warrants or the agreement by them to subscribe for or purchase any Placing Shares and Warrants.

No representation or warranty express or implied, is or will be made as to, or in relation to, and no responsibility or liability is or will be accepted by the Joint Bookrunners or by any of their respective affiliates or agents as to or in relation to, the accuracy or completeness of the Exchange Information (including this Announcement) or any other written or oral information made available to or publicly available to any interested party or its advisers, and any liability therefore is expressly disclaimed.

Forward Looking Information

This Announcement contains certain forward-looking information (collectively referred to herein as "forward-looking statements") within the meaning of applicable Canadian securities laws. Forward-looking statements are often, but not always, identified by the use of words such as "forecast", "guidance", "outlook", "anticipate", "target", "plan", "continue", "intend", "consider", "estimate", "expect", "may", "will", "should", "could" (or the negatives or similar words suggesting future outcomes. Forward-looking statements in this Announcement may contain, but are not limited to, statements concerning: Southern's business strategy and plan, including its objectives, strengths and focus; the completion of the Fundraising and the terms, size and timing thereof and the use of proceeds therefrom (alongside existing cash, cash flows and undrawn debt facilities), including the acceleration of the completion of three Gwinville DUC wells and two Mechanicsburg drills; the completion of the Debenture Amendment and the issuance of the Common Shares; the Company's price dependent growth and acquisition and consolidation strategies, including targets, metrics, planned investments, and allocation of funds, anticipated operational results; capital expenditures and drilling plans and locations the performance characteristics of the Company's oil and natural gas properties; the ability of the Company to achieve drilling success consistent with management's expectations; and the source of funding for the Company's activities including development costs.

The forward-looking statements contained in this Announcement are based on a number of factors and assumptions made by Southern, which have been used to develop such statements, but which may prove to be incorrect. In addition to factors and assumptions which may be identified in this press release, assumptions have been made regarding and may be implicit in, among other things: the business plan of Southern; the receipt of all approvals and satisfaction of all conditions to the completion of the Fundraising; the timing of and success of future drilling, development and completion activities; the geological characteristics of Southern's properties; prevailing commodity prices, price volatility, price differentials and the actual prices received for the Company's products; the availability and performance of drilling rigs, facilities, pipelines and other oilfield services; the timing of past operations and activities in the planned areas of focus; the drilling, completion and tie-in of wells being completed as planned; the performance of new and existing wells; the application of existing drilling and fracturing techniques; prevailing weather and break-up conditions; royalty regimes and exchange rates; the application of regulatory and licensing requirements; the continued availability of capital and skilled personnel; the ability to maintain or grow the banking facilities; the accuracy of Southern's geological interpretation of its drilling and land opportunities, including the ability of seismic activity to enhance such interpretation; and Southern's ability to execute its plans and strategies. Readers are cautioned that the foregoing list is not exhaustive of all factors and assumptions which have been used.

Although management considers these assumptions to be reasonable based on information currently available, undue reliance should not be placed on the forward-looking statements because Southern can give no assurances that they may prove to be correct. By their very nature, forward-looking statements are subject to certain risks and uncertainties (both general and specific) that could cause actual events or outcomes to differ materially from those anticipated or implied by such forward-looking statements. As a result, any potential investor should not rely on such forward-looking statements in making their investment decisions. No representation or warranty is made as to the achievement, or reasonableness of, and no reliance should be placed on such forward-looking statements. Risks and uncertainties that can materially impact the Company's results include, but are not limited to: incorrect assessments of the value of benefits to be obtained from exploration and development programs; changes in the financial landscape both domestically and abroad, including volatility in the stock market and financial system; wars (including Russia's war in Ukraine and conflicts in the Middle East); risks associated with the oil and gas industry in general (e.g. operational risks in development, exploration and production, delays or changes in plans with respect to exploration or development projects or capital expenditures, and environmental regulations); commodity prices; increased operating and capital costs due to inflationary pressures; the uncertainty of estimates and projections relating to production, cash generation, costs and expenses; health, safety, litigation and environmental risks; access to capital; the availability of future financings and divestitures; public and political sentiment towards fossil fuels; and the effects of pandemics and other public health events. Due to the nature of the oil and natural gas industry, drilling plans and operational activities may be delayed or modified to react to market conditions, results of past operations, regulatory approvals or availability of services causing results to be delayed. Please refer to Southern's most recent Annual Information Form for the year ended December 31, 2023 and management's discussion and analysis for the period ended September 30, 2024, and other continuous disclosure documents for additional risk factors relating to Southern, which can be accessed either on Southern's website at www.southernenergycorp.com or under the Company's profile on www.sedarplus.ca.
