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", "expect", "plan", "intend", "estimate", "propose", "project" or similar words suggesting future outcomes or statements regarding an outlook. The forward-looking statements contained in this press release are based on certain key expectations and assumptions made by Southern. 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); the uncertainty of reserve estimates; the uncertainty of estimates and projections relating to production, costs and expenses, and health, safety and environmental risks; the impact of pandemics; constraint in the availability of labour, supplies or services; commodity price and exchange rate fluctuations; geo-political risks, political and economic instability abroad and wars (including the Russo-Ukrainian war and the Israel-Palestinian conflict); changes in legislation impacting the oil and gas industry; inflationary risks, including potential increases to operating and capital costs; 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 and the Israel-Palestinian conflict are particularly noteworthy, as these conflicts have the potential to disrupt the global supply of oil and gas, and their full impact remains uncertain. Other risks faced by the Company are set out in more detail in Southern's Annual Information Form for the year ended December 31, 2022, which is available under the Company's SEDAR+ profile at www.sedarplus.ca.
