SOUTHERN ENERGY CORP. ANNOUNCES PROPOSED EQUITY FUNDRAISING

Calgary, Alberta - 1 November 2023 - Southern Energy Corp. ("Southern" or the "Company") (TSXV:SOU) (AIM:SOUC) (OTCQX:SOUTF) is pleased to announce its intention to conduct an equity fundraise to raise aggregate gross proceeds of at least US$5 million (approximately £4.1 million / C$6.9 million), at a price of 15.5 pence (the "Placing Price") or C$0.26 per Common Share (the "Prospectus Price").

The fundraising consists of a placing of new Common Shares to new and existing institutional investors (the "Placing"), a concurrent public offering of new Common Shares in Canada (the "Prospectus Offering"), and a Subscription by certain Directors and members of the Company's senior management (together with the Placing and Prospectus Offering, the "Fundraising").

The Fundraising will launch immediately following the release of this Announcement. Stifel Nicolaus Europe Limited ("Stifel Europe") and Tennyson Securities, a trading name of Shard Capital Partners LLP ("Tennyson Securities") are acting as joint bookrunners (the "Joint Bookrunners") in connection with the Placing. Stifel Nicolaus Canada Inc. ("Stifel Canada") is acting as lead agent and sole bookrunner in connection with the Prospectus Offering.

Overview of the Fundraising

· Southern intends to conduct a US$5 million equity fundraise to accelerate the completion of its four drilled and uncompleted ("DUC") wells, drilled as part of its Q1 2023 drilling campaign on its Gwinville acreage;

· The accelerated completion of the DUCs is anticipated to be accretive to Southern through the addition of approximately US$20.5 million⁽¹⁾ in proved developed producing ("PDP") NPV10 value;

· The Company expects the DUCs, once completed, to have initial production (IP30) rates of approximately 5.6 MMcf/d per well, with expected ultimate recovery per well of approximately 4.3 Bcf;

· The DUCs are forecast to have a per-well payback period of approximately 12 months, with an associated IRR of 108% and NPV10 of US$4.4 million per well⁽²⁾;

· Subject to the successful completion of the DUCs and achieving production rates as set out above (and assuming one completion a quarter* and strip commodity pricing as at 5 October 2023), Southern would expect to generate next 12 months total operating cash flow⁽³⁾ of approximately US$20 million, resulting in an annualised net debt to EBITDA ratio⁽³⁾ of approximately 1.0x in Q4 2024⁽¹⁾, with next 12 months corporate free cash flow⁽³⁾ expected to increase to approximately US$13 million, an increase of approximately 114% on a per share basis following the planned Fundraising⁽¹⁾;

* It is noted that timing of the completions is subject to final confirmation following appointment of contractors and may differ from this illustrative schedule.

· Completion of the DUCs provides Southern with a significant platform for organic growth, with production expected to reach up to 4,700 boepd in 2024, an increase of 39% per share, including the Fundraising, and with PDP reserves expected to increase by 12% per share;

· The Company has identified over 100 additional horizontal drilling targets at Gwinville which it will target for development in appropriate gas price environments. Based on the expected drilling and completion costs for new wells of US$5.5 million, future wells are expected to achieve a ~30% IRR at a natural gas price of US$3.78 / MMBtu;

· The net proceeds from the Fundraising will be used alongside existing cash, cash flows and undrawn debt facilities to fund the completion of the DUCs at a cost of approximately US$3 million per well;

· The Fundraising consists of:

o A Placing of new Common Shares (the "Placing Shares") 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 Common Shares (the "Prospectus Shares") on a best efforts agency basis at the Prospectus Price. The Prospectus Offering will be conducted pursuant to the terms and conditions of an agency agreement to be entered into between the Company, Stifel Canada as sole bookrunner and lead agent, Canaccord Genuity Corp, Eight Capital, and Haywood Securities Inc (the "Agents"). The size of the Prospectus Offering will be determined in the context of the market at the time of entering into a definitive agency agreement between the Company and the Agents; and

o A subscription for new Common Shares (the "Subscription Shares") at the Placing Price by certain Directors and members of the Company's senior management.

· The Prospectus Offering will be conducted pursuant to the Company's Canadian base shelf prospectus dated 18 November 2022 (the "Base Shelf Prospectus"). A prospectus supplement (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 will be available under the Company's profile on SEDAR+ at www.sedarplus.ca. The Prospectus Offering is expected to close on or around 9 November 2023.

· The number of Placing Shares and Prospectus Shares to be issued will be determined by the Company following completion of the Bookbuild in consultation with the Joint Bookrunners and Stifel Canada.

· The Bookbuild is currently expected to close no later than 8.00 a.m. (GMT) on 2 November 2023, but the Joint Bookrunners and the Company reserve the right to close the Bookbuild earlier or later, without further notice.

Ian Atkinson, President and CEO of Southern, commented:

"I am pleased to announce our proposed Fundraising today, which will facilitate the acceleration of Southern's work program, specifically the completion of our four drilled and uncompleted wells in our Gwinville acreage in Mississippi. After pausing our previous capital program at the end of Q1 2023 due to the drop in natural gas prices, we are excited to soon be back in the field at Gwinville to take advantage of the recent increase in Henry Hub natural gas pricing and bring these four uncompleted wells into production. We have made a significant capital investment in the four DUC wells and will now be in a position to realize the material cashflow generation from these wells as we rapidly increase production in a short timescale. Our current cost estimates to complete these wells suggests at least a 10-15% drop from the cost levels seen in Q1 2023, due to lower industry activity levels which will help drive superior returns.

"We continue to see an increasingly positive macro environment for the US natural gas market, and we believe that Southern is firmly positioned to capitalize on the opportunity presented to us through this structural imbalance. Today's capital raise will enable us to increase our exposure to the opportunity, as we see gas prices react to increasing export capacity through the U.S. Gulf Coast region and increasing natural gas fired power in the US. I look forward to allocating the raised capital to our portfolio of highly productive and profitable assets, and increasing shareholder value as we enter a resurgent US natural gas market."

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 have been subject to a product approval process, which has determined that the Placing Shares 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").

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.

6. Allocations of the Placing Shares 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 allocated to it at the Placing Price 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.

8.

The Joint Bookrunners may also, notwithstanding paragraphs 4 and 5 above, subject to the prior consent of the Company, allocate Placing Shares 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".

13.

2. each of the conditions to the Prospectus Offering which are to be fulfilled prior to Admission having been fulfilled or (if capable of waiver) waived by Stifel Canada and not having become incapable of being fulfilled, in each case by the respective time(s) and date(s) (if any) specified therein;

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 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;

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.

The Placing Shares 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 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. 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: CA8428131059) 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 9 November 2023 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 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 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 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 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 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. 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 or the agreement by them to subscribe for or purchase any Placing Shares.

The Exchange Information has been issued by, and is the sole responsibility, of the Company. 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.

Stifel Nicolaus Europe Limited, which is authorised and regulated by the Financial Conduct Authority in the United Kingdom is acting exclusively for the Company and no one else in connection with the Placing and Admission, and Stifel Europe will not be responsible to anyone other than the Company for providing the protections afforded to its clients or for providing advice in relation to the Placing or Admission or any other matters referred to in this Announcement.

Definitions

In this Announcement (including the Terms and Conditions), the following words and expressions shall (save where the context otherwise requires) have the following meanings:

READER ADVISORY

Currency. All currency amounts in this Announcement are in United States dollars (unless otherwise stated).

Disclosure of Oil and Gas Information

Unit Cost Calculation. Natural gas liquids volumes are recorded in barrels of oil (bbl) and are converted to a thousand cubic feet equivalent (Mcfe) using a ratio of six (6) thousand cubic feet to one (1) barrel of oil (bbl). Natural gas volumes recorded in thousand cubic feet (Mcf) are converted to barrels of oil equivalent (boe) using the ratio of six (6) thousand cubic feet to one (1) barrel of oil (bbl). Mcfe and boe may be misleading, particularly if used in isolation. A boe conversion ratio of 6 mcf:1 bbl or a Mcfe conversion ratio of 1 bbl:6 Mcf is based in an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. In addition, given that the value ratio based on the current price of oil as compared with natural gas is significantly different from the energy equivalent of six to one, utilizing a boe conversion ratio of 6 Mcf:1 bbl or a Mcfe conversion ratio of 1 bbl:6 Mcf may be misleading as an indication of value.

Product Types. References to "natural gas" throughout this Announcement refer to conventional natural gas as defined by NI 51-101.

Reserves Disclosure. All reserves values and ancillary information contained in this Announcement have been internally estimated by the Company's Internal Qualified Reserve Evaluator ("QRE") and prepared in accordance with National Instrument 51-101 - Standards of Disclosure for Oil and Gas Activities ("NI 51-101") and the most recent publication of the Canadian Oil and Gas Evaluation Handbook ("COGEH"). "Internally estimated" means an estimate that is derived by the Company's internal QRE and prepared in accordance with NI 51-101. All reserve references in this Announcement are "company gross reserves". Estimates of reserves for individual properties may not reflect the same level of confidence as estimates of reserves for all properties, due to the effect of aggregation.

Drilling Locations. This Announcement discloses drilling locations in two categories: (i) booked locations; and (ii) unbooked locations. Booked locations are derived from the Company's internal reserves evaluation as prepared by a member of management who is a QRE in accordance with NI 51-101 and the most recent publication of the COGEH effective 5 October 2023 and account for drilling locations that have associated proved and/or probable reserves, as applicable. Unbooked locations are internal estimates based on the prospective acreage and an assumption as to the number of wells that can be drilled per section based on industry practice and internal review. Unbooked locations do not have attributed reserves or resources. There is no certainty that the Company will drill all unbooked drilling locations and if drilled there is no certainty that such locations will result in additional oil and gas reserves, resources or production. The drilling locations considered for future development will ultimately depend upon the availability of capital, regulatory approvals, seasonal restrictions, oil and natural gas prices, costs, actual drilling results, additional reservoir information that is obtained and other factors. While certain of the unbooked drilling locations have been derisked by drilling existing wells in relative close proximity to such unbooked drilling locations, other unbooked drilling locations are farther away from existing wells where management has less information about the characteristics of the reservoir and therefore there is more uncertainty whether wells will be drilled in such locations and if drilled there is more uncertainty that such wells will result in additional oil and gas reserves, resources or production.

Proved reserves are those reserves that can be estimated with a high degree of certainty to be recoverable. It is likely that the actual remaining quantities recovered will exceed the estimated proved reserves. Probable reserves are those additional reserves that are less certain to be recovered than proved reserves. It is equally likely that the actual remaining quantities recovered will be greater or less than the sum of the estimated proved plus probable reserves. Proved developed producing reserves are those reserves that are expected to be recovered from completion intervals open at the time of the estimate. These reserves may be currently producing or, if shut-in, they must have previously been on production, and the date of resumption of production must be known with reasonable certainty. Undeveloped reserves are those reserves expected to be recovered from known accumulations where a significant expenditure (e.g., when compared to the cost of drilling a well) is required to render them capable of production. They must fully meet the requirements of the reserves category (proved, probable, possible) to which they are assigned. Certain terms used in this Announcement but not defined are defined in NI 51-101, CSA Staff Notice 51-324 - Revised Glossary to NI 51-101, Revised Glossary to NI 51-101, Standards of Disclosure for Oil and Gas Activities ("CSA Staff Notice 51-324") and/or the COGEH and, unless the context otherwise requires, shall have the same meanings herein as in NI 51-101, CSA Staff Notice 51-324 and the COGEH, as the case may be.

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, including the acceleration of the completion of up to four DUC wells; 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. Statements relating to production, reserves, recovery, replacement, costs and valuation are also deemed to be 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 that the reserves can be profitably produced in the future.

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 the Israel-Palestinian conflict); 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 (including but not limited to COVID-19). 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.

The forward-looking statements contained in this Announcement are made as of the date hereof and the Company does not undertake any obligation to update publicly or to revise any of the included forward-looking statements, except as required by applicable law. The forward-looking statements contained herein are expressly qualified by this cautionary statement.

This Announcement contains future-oriented financial information and financial outlook information (collectively, "FOFI") about Southern's prospective results of operations, the performance of the DUCs, once completed, including having IP30 rates of approximately 5.6 MMcf/d per well and ultimate recovery per well of approximately 4.3 Bcf, operating costs, including an anticipated costs of US$5.5 million per well which would achieve a ~30% IRR at a natural gas price of US$3.78 / MMBtu, payout of wells, including expectations that the DUCs will payout in 12 months with associated IRR of 108% and NPV10 of US$4.4 million per well, expectations of generating next twelve months operating cash flow of approximately US$20 million, resulting in an annualised net debt to EBITDA ratio of approximately 1.0x in Q4 2024, increasing next twelve months corporate free cash flow to approximately US$13 million; achieving production of approximately 4,700 boepd in 2024, with PDP reserves increasing by 12% per share cash flow, and components thereof, including pro forma the completion of the Fundraising, all of which are subject to the same assumptions, risk factors, limitations, and qualifications as set forth in the above paragraphs. FOFI contained in this Announcement was approved by management as of the date of this Announcement and was provided for the purpose of providing further information about Southern's future business operations. Southern and its management believe that FOFI has been prepared on a reasonable basis, reflecting management's best estimates and judgments, and represent, to the best of management's knowledge and opinion, the Company's expected course of action. However, because this information is highly subjective, it should not be relied on as necessarily indicative of future results. Southern disclaims any intention or obligation to update or revise any FOFI contained in this Announcement, whether as a result of new information, future events or otherwise, unless required pursuant to applicable law. Readers are cautioned that the FOFI contained in this Announcement should not be used for purposes other than for which it is disclosed herein.

References in this press release to peak rates, initial production rates, IP30 and other short-term production rates are useful in confirming the presence of hydrocarbons, however such rates are not determinative of the rates at which such wells will commence production and decline thereafter and are not indicative of long-term performance or of ultimate recovery. While encouraging, readers are cautioned not to place reliance on such rates in calculating the aggregate production of Southern.

Specified Financial Measures

This Announcement provides various financial measures that do not have a standardized meaning prescribed by IFRS, including non-IFRS financial measures, non-IFRS financial ratios and capital management measures. These specified financial measures may not be comparable to similar measures presented by other issuers. Southern's method of calculating these measures may differ from other companies and accordingly, they may not be comparable to measures used by other companies. Corporate free cash flow, EBITDA and net debt are not recognized measures under IFRS. Readers are cautioned that these specified financial measures should not be construed as alternatives to other measures of financial performance calculated in accordance with IFRS. These specified financial measures provide additional information that management believes is meaningful in describing the Company's operational performance, liquidity and capacity to fund capital expenditures and other activities. Please see below for a brief overview of all specified financial measures used in this release and refer to the Company's MD&A for additional information relating to specified financial measures, which is available on the Company's website at www.southernenergycorp.com and filed on SEDAR.

"Corporate Free Cash Flow" (capital management measure) is calculated by taking cash-flow from operating activities and adding back changes in non-cash working capital, expenditures on decommissioning obligations and transaction costs and subtracting capital expenditures, excluding acquisitions and dispositions. Management believes that free cash flow provides a useful measure to determine Southern's ability to improve returns and to manage the long-term value of the business.

"EBITDA" (non-IFRS financial measure) is calculated as consolidated net income (loss) before interest and financing expenses, income taxes, depletion, depreciation and amortization, adjusted for certain non-cash, extraordinary and non-recurring items primarily relating to unrealized gains and losses on financial instruments and impairment losses. The Company considers this metric as key measures that demonstrate the ability of the Company's continuing operations to generate the cash flow necessary to maintain production at current levels and fund future growth through capital investment and to service and repay debt. The most directly comparable IFRS measure to EBITDA is cash provided by operating activities.

"Net Debt" (capital management measure) is monitored by Management, along with adjusted working capital, as part of its capital structure in order to fund current operations and future growth of the Company. Net debt is defined as long-term debt plus adjusted working capital surplus or deficit. Adjusted working capital is calculated as current assets less current liabilities, removing current derivative assets/liabilities, the current portion of bank debt, and the current portion of lease liabilities.

"Net Debt to EBITDA"(non-IFRS financial ratio) is calculated as net debt at a point in time divided by EBITDA. Management considers Net Debt to EBITDA an important measure as it is a key metric to identify the Company's ability to fund financing expenses, net debt reductions and other obligations. When this measure is presented quarterly, EBITDA is annualized by multiplying by four.

"Operating Cash Flow" (non-IFRS financial measure) is calculated as revenue less royalties, transportation, operating expenses and production taxes.
