SOUTHERN ENERGY CORP. PROVIDES OPERATIONAL UPDATE

Calgary, Alberta - October 17, 2023 - Southern Energy Corp. ("Southern" or the "Company") (TSXV:SOU) (AIM:SOUC)(OTCQX:SOUTF), an established producer with natural gas and light oil assets in Mississippi, is pleased to provide an update on field operations and production, as well as recent financial hedging contracts that have been executed.

Operations Update

Production for the third quarter averaged 2,814 boe/d (95% natural gas), representing a 6% increase over the prior quarter and largely reflecting the impact of the synergistic Gwinville acquisition (the "Transaction") completed in June 2023. Current production is approximately 2,900 boe/d.

At Gwinville, Southern has completed the process of installing the necessary pipeline infrastructure to consolidate the two gathering systems, allowing the Company to run just one central compressor station compared to the five that were running before the Transaction. These synergies will not only remove costly rental compression and allow monetization of spare owned compressors but will also eliminate the need for approximately 250 Mcf/d of fuel gas and associated emissions which can instead be added directly into sales volumes. Additionally, the Company has recently initiated workover operations on two shut-in wells on the acquired lands to re-establish production. The wells were previously producing at a combined rate of approximately 800 Mcf/d.

In September, the Company attempted to mechanically remediate the casing on the 18-10 #3 Upper Selma Chalk horizontal well without success. Subsequently, the heel section of the lateral (10 of 48 stages, 1,060 feet total lateral length, and 740 feet of effective lateral length) was turned over to production and the well is currently flowing at a restricted rate of 1.2 MMcf/d. The Company is considering alternative casing remediation methods for possible execution in Q1 2024.

In light of the recent recovery in U.S. natural gas prices above $3/MMBtu, the Company is also in the process of re-bidding completion services in connection with the four high quality uncompleted horizontal wells at Gwinville.

Ian Atkinson, President and Chief Executive Officer of Southern, commented:

"We are excited with the progress we have made with the Gwinville acquisition integration, realizing quick and incremental value for shareholders through operating cost reductions and now through the start of work to increase production on the asset. At the time of pausing our capital program in Q1 2023, in response to the price of gas reaching $2.00/MMBtu, we had made a significant investment including four drilled uncompleted horizontal wells ("DUCs"), incremental Company owned field compression, wellhead facilities, Company owned water disposal capacity, and well casing for future drilling. This pre-investment positions Southern to expedite our corporate growth in light of the recent improvements in the price of U.S. natural gas and the anticipated drop in the cost of services. We look forward to updating the market further as we make key operational decisions in light of resurgent US natural gas prices."

Recent Financial Hedging Initiatives

With the recent natural gas price recovery, Southern has taken the opportunity to add further hedges, both in the near term and through the 2024 and 2025 calendar years, to protect future cash flows and ensure balance sheet resiliency through the commodity price cycle. Natural gas prices have been under pressure through the beginning of 2023, with the Q2 2023 Henry Hub price averaging $2.10/MMBtu, improving to $2.55/MMBtu in Q3 2023, and is currently at approximately $3.20/MMBtu. The Company's hedge contracts, listed below, will ensure a strong natural gas price floor, allowing Southern the ability to execute and capitalize on its organic operational plans over the coming years.

Southern thanks all of its stakeholders for their ongoing support and looks forward to providing future updates on operational activities and continuing to create shareholder value.

READER ADVISORY

MCFE Disclosure. 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.

Throughout this press release, "crude oil" or "oil" refers to light and medium crude oil product types as defined by National Instrument 51-101 - Standards of Disclosure for Oil and Gas Activities ("NI 51-101"). References to "NGLs" throughout this press release comprise pentane, butane, propane, and ethane, being all NGLs as defined by NI 51-101. References to "natural gas" throughout this press release refers to conventional natural gas as defined by NI 51-101.

Unit Cost Calculation. For the purpose of calculating unit costs, natural gas volumes have been converted to a boe using six thousand cubic feet equal to one barrel unless otherwise stated. A boe conversion ratio of 6:1 is based upon an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. This conversion conforms with NI 51-101. Boe may be misleading, particularly if used in isolation.

Although Southern believes that the expectations and assumptions on which the forward-looking statements are based are reasonable, undue reliance should not be placed on the forward-looking statements because Southern can give no assurance that they will prove to be correct. Since forward-looking statements address future events and conditions, by their very nature they involve inherent risks and uncertainties. Actual results could differ materially from those currently anticipated due to a number of factors and risks. These include, but are not limited to, risks associated with the oil and gas industry in general (e.g., operational risks in development, exploration and production; the uncertainty of reserve estimates; the uncertainty of estimates and projections relating to production, costs and expenses, regulatory risks, and health, safety and environmental risks), constraint in the availability of labour, supplies, or services, the impact of COVID-19 and variant strains of the virus, commodity price and exchange rate fluctuations, geo-political risks, political and economic instability abroad, wars (including the Russo-Ukrainian War), hostilities, civil insurrections, inflationary risks including potential increases to operating and capital costs, changes in legislation impacting the oil and gas industry, adverse weather or break-up conditions, and uncertainties resulting from potential delays or changes in plans with respect to exploration or development projects or capital expenditures. The Russo-Ukrainian War is particularly noteworthy, as this conflict has the potential to disrupt the global supply of oil and gas, and its full impact remains uncertain. These and other risks are set out in more detail in Southern's management's discussion and analysis for the period ended June 30, 2023, and annual information form for the year ended December 31, 2022, which are available on the Company's website at www.southernenergycorp.com and filed under the Company's profile on SEDAR+ at www.sedarplus.ca.
