Southern Energy Corp. Announces 2018 Year-End Reserves

CALGARY, March 19, 2019 - Southern Energy Corp. ("Southern" or the "Corporation") (SOU: TSXV) is pleased to provide a summary of our 2018 year-end reserves. Reserve numbers presented herein were derived from an independent reserves report (the "NSAI Report") prepared by Netherland, Sewell & Associates, Inc. ("NSAI"), effective December 31, 2018.

"I am very pleased with our year-end reserves update", said Ian Atkinson, President and Chief Executive Officer of the Corporation.  "It highlights the quality of the assets we have acquired in the U.S. Gulf Coast region and supports our strategy to grow through consolidation and organic growth in this area of premium commodity prices."

"Although Southern is relatively new to the Canadian public market space," added Mr. Atkinson, "we have years of operating experience in these areas and look forward to unlocking value for our shareholders."

HIGHLIGHTS

• Proved developed producing ("PDP") net present value of $37.1 MM on a before tax basis, discounted at 10%. Total Proved ("TP") net present value of $73.4 MM.
• Year over year PDP reserve increase of 5.2 MMboe, primarily associated with the acquisition of the Gulf Pine Energy U.S. assets in December 2018; represents a PDP Finding, Development and Acquisition ("FD&A") cost of $6.45/boe.
• Year over year TP reserve increase of 11.0 MMboe, representing a TP FD&A cost of $3.03/boe.
• Based on a management-estimated current operating netback of $12.50/boe, the TP FD&A recycle ratio for 2018 is 4.1.
• Base PDP decline on Southern's U.S. assets estimated at less than 13% for 2019.

Forward Looking and Cautionary Statements

Forward Looking Statements.  Certain information included in this press release constitutes forward-looking information under applicable securities legislation. Forward-looking information typically contains statements with words such as "anticipate", "believe", "will", "expect", "plan", "intend", "estimate", "propose", "project" or similar words suggesting future outcomes or statements regarding an outlook. Forward-looking information in this press release may include, but is not limited to, statements about our corporate strategy, timing and level of capital expenditures, anticipated cost savings, future acquisition opportunities, future production levels, drilling locations, estimated net asset value and future development costs associated with oil and gas reserves. Statements relating to "reserves" 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 press release are based on certain key expectations and assumptions made by the Corporation, including expectations and assumptions concerning the success of future drilling, development and completion activities, the performance of existing wells, the performance of new wells, the availability and performance of facilities and pipelines, the geological characteristics of the Corporation's properties, the successful application of drilling, completion and seismic technology, prevailing weather and break-up conditions, commodity prices, royalty regimes and exchange rates, the application of regulatory and licensing requirements, the availability of capital, labour and services, the creditworthiness of industry partners and our ability to acquire additional assets.

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 the Corporation 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, and health, safety and environmental risks), constraint in the availability of services, commodity price and exchange rate fluctuations, 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. Production forecasts are directly impacted by commodity prices and the actual timing of our capital expenditures.  Actual results may vary materially from forecasts due to changes in interest rates, oil differentials, exchange rates and the timing of expenditures and production additions. These and other risks are set out in more detail in our continuous disclosure.

The forward-looking information contained in this press release is made as of the date hereof and the Corporation undertakes no obligation to update publicly or revise any forward-looking information, whether as a result of new information, future events or otherwise, unless required by applicable securities laws. The forward looking information contained in this press release is expressly qualified by this cautionary statement.

Oil and Gas Advisories

BOE Disclosure.  The term barrels of oil equivalent ("BOE") may be misleading, particularly if used in isolation.  A BOE conversion ratio of six thousand cubic feet of natural gas to barrels of oil equivalence is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.  All BOE conversions in the report are derived from converting gas to oil in the ratio mix of six thousand cubic feet of gas to one barrel of oil.

Reserves Disclosure.  It should not be assumed that the present worth of estimated future cash flow presented in the tables above represents the fair market value of the reserves. There is no assurance that the forecast prices and costs assumptions will be attained and variances could be material. The recovery and reserve estimates of the Corporation's crude oil, natural gas liquids and natural gas reserves provided herein are estimates only and there is no guarantee that the estimated reserves will be recovered. Actual crude oil, natural gas and natural gas liquids reserves may be greater than or less than the estimates provided herein. All future net revenues are estimated using forecast prices, arising from the anticipated development and production of our reserves, net of the associated royalties, operating costs, development costs, and abandonment and reclamation costs and are stated prior to provision for interest and general and administrative expenses. Future net revenues have been presented on a before tax basis. Estimated values of future net revenue disclosed herein do not represent fair market value.

Oil and Gas Metrics.  This press release contains metrics commonly used in the oil and natural gas industry, such as finding, development and acquisition costs, recycle ratio and operating netback. These terms do not have a standardized meaning and may not be comparable to similar measures presented by other companies, and therefore should not be used to make such comparisons. Management uses these oil and gas metrics for its own performance measurements and to provide shareholders with measures to compare Southern's operations over time. Readers are cautioned that the information provided by these metrics, or that can be derived from the metrics presented in this press release, should not be relied upon for investment or other purposes.

Finding, development and acquisition costs are derived by dividing the sum of total net capital expenditures by the sum of total additions and revisions for the relevant reserves category. The Corporation considers FD&A costs a key measure in evaluating its performance as it provides an understanding of the Corporation's ability to effectively find and develop reserves and add to the Corporation's reserve base.

Recycle ratio is derived by dividing the operating netback by the FD&A cost for the relevant reserves category. Operating netback is derived as product sales net of blending costs, less royalties, transportation and production expenses, calculated on a per BOE basis. The Corporation considers recycle ratio a key measure in evaluating the Corporation's ability to generate profitability on its capital investment.

Non-IFRS Measures. This press release provides certain financial measures that do not have a standardized meaning prescribed by IFRS, such as net asset value and net debt. These non-IFRS financial measures may not be comparable to similar measures presented by other issuers.

Net asset value is derived by subtracting the Corporation's net debt from the net present values of estimated future net revenues (before tax and discounted at 10%). Net debt represents current assets less current liabilities, excluding current derivative financial instruments, and is used to assess efficiency, liquidity and the general financial strength of the Corporation. The Corporation considers net asset value a key measure of the Corporation's oil and gas asset value.

Financial Information. Southern's audited financial statements for the 2018 year-end have not been completed. All financial information presented in this press release is based on estimates and is unaudited and subject to change.

Neither TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.
