Company Announcements

TSX: TVE

CALGARY, AB , Sept. 18, 2025 /CNW/ - Tamarack Valley Energy Ltd. is pleased to announce it has entered into a definitive agreement with a private company to sell its remaining non-core producing assets in the Veteran Consort and Eyehill areas of Eastern Alberta for $112.0 million before closing adjustments (the "East Asset Divestiture").

Transaction Highlights

• Asset focus – completes Tamarack's transformation into a pure-play Clearwater and Charlie Lake producer
• Costs – Net production expenses per boe⁽¹⁾ expected to improve by ~10% from the disposition of lower margin barrels
• Guidance – No change to 2025 full year production guidance; 2026 budget to be released in late Q4 2025

East Asset Divestiture
Tamarack is selling its two remaining non-core producing assets in Eastern Alberta for cash consideration of $112.0 million before closing adjustments, and the assumption of undiscounted asset retirement obligations of $63 million (~50% inactive). The transaction is expected to close in October 2025, subject to customary closing considerations.

The East Assets currently produce approximately 4,000 boe per day (3,500 bbl per day of oil), or 6% of Tamarack's corporate production. Over the next 12 months, the East Assets were expected to generate field operating netbacks⁽¹⁾ of approximately $45 million, reflecting a before-tax transaction multiple of ~2.5x at current strip prices.

The East Assets were undercapitalized in Tamarack's portfolio with developments focused primarily on the core Clearwater and Charlie Lake assets. The transaction reduces the Company's asset retirement obligations by $63 million (on an undiscounted basis), reflecting 25% of the Company's total corporate liability and includes ~40% of Tamarack's total inactive decommissioning obligations. The transaction is also expected to improve Tamarack's net production expenses per boe⁽¹⁾ by ~10% as the East Assets carry higher operating costs on a per barrel basis relative to the Company's corporate average.

The Company has now successfully completed its transformation into a pure-play Clearwater and Charlie Lake player. Over the past three years, Tamarack has divested of a number of non-core assets following strategic acquisitions, creating a solid financial foundation for future development and growth of the Company's high-graded, top-tier assets.

Outlook
Tamarack continues to prioritize net debt⁽¹⁾ reduction together with ongoing returns to shareholders in the form of dividends and common share buybacks under its return of capital framework. Proceeds from the divestiture will initially be utilized to reduce net debt⁽¹⁾ providing the Company with future optionality to increase shareholder returns or accelerate ongoing development in the Clearwater, including expanded waterflood initiatives. Tamarack expects the East Asset Divestiture will be accretive to the Company's five-year plan, reinforced by lower net production expenses and higher margins on a per boe basis and lower near-term asset retirement obligation expenditures. Tamarack continues to forecast reaching its net debt⁽¹⁾ target of $500 million in 2027 under its long-term plan at a WTI price of US$65 per barrel.

The Company's 2025 guidance remains mostly unchanged for the full year, primarily due to outperformance from the H1 2025 development programs, Clearwater waterflood response and a tuck-in acquisition of additional Clearwater assets early in the third quarter. Full year production outlook remains at 67,000 to 69,000 boe per day with fourth quarter production expected to be 66,500 to 67,500 boe per day. Tamarack's annual net production expenses⁽¹⁾ for 2025 are expected to be $7.75 - $8.25 per boe, a $0.25 per boe reduction compared to previous guidance as result of the portfolio optimization. Tamarack plans to release its 2026 budget later in the fourth quarter of 2025.

Reader Advisories
Disclosure of Oil and Gas Information
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 Canadian Securities Administrators' National Instrument 51 101 - Standards of Disclosure for Oil and Gas Activities ("NI 51-101"). Boe may be misleading, particularly if used in isolation. References in this press release to "crude oil" or "oil" refers to light, medium and heavy crude oil product types as defined by NI 51-101. References to "NGL" throughout this press release comprise pentane, butane, propane, and ethane, being all NGL 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.

2025 production guidance of 67,000 – 69,000 boe per day is comprised of 41,150 - 42,350 bbl per day heavy oil, 13,300 - 13,700 bbl per day light and medium oil, 2,300 - 2,360 bbl per day natural gas liquids and 61,550 - 63,550 mcf per day natural gas. Q4 2025 production guidance of 66,500 – 67,500 boe per day consists of 44,250 - 44,500 bbl per day heavy oil, 9,750 - 10,000 bbl per day light/medium oil, 2,200 - 2,300 bbl per day natural gas liquids and 62,000 - 64,000 mcf per day natural gas.

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 Tamarack 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. These risks and uncertainties include, but are not limited to: the risk that the East Asset Divestiture will not be completed on the terms anticipated or at all, including due to a closing condition not being satisfied; the risk that the Company utilize the proceeds from the East Asset Divestiture other than in the manners described in this press release; risks with respect to unplanned third party pipeline outages and risks relating to inclement and severe weather events and natural disasters, such as fire, drought and flooding, including in respect of safety, asset integrity and shutting-in production; the risk that future dividend payments thereunder are reduced, suspended or cancelled; incorrect assessments of the value of benefits to be obtained from exploration and development programs; risks associated with the oil and gas industry in general (e.g. operational risks in development, exploration and production; and delays or changes in plans with respect to exploration or development projects or capital expenditures); the risk that (i) ongoing negotiations between the U.S. and Canadian governments are not successful and one or both of such governments maintain tariffs, increase the rate or scope of tariffs, or impose new tariffs on the import of goods from one country to the other, including on oil and natural gas, (ii) the U.S. and/or Canada imposes any other form of tax, restriction or prohibition on the import or export of products from one country to the other, including on oil and natural gas, and (iii) the tariffs imposed by the U.S. on other countries and responses thereto could have a material adverse effect on the Canadian, U.S. and global economies, and by extension the Canadian oil and natural gas industry and the Company; commodity prices, including the impact of the actions of OPEC and OPEC+ members; the uncertainty of estimates and projections relating to production, cash generation, costs and expenses, including increased operating and capital costs due to inflationary pressures; health, safety, litigation and environmental risks; access to capital; and pandemics. In addition, ongoing military actions in the Middle East and between Russia and Ukraine have the potential to threaten the supply of oil and gas from those regions. The long-term impacts of the actions between these nations remains uncertain. Due to the nature of the oil and natural gas industry, drilling plans and operational activities may be delayed or modified to respond to market conditions, results of past operations, regulatory approvals or availability of services causing results to be delayed. Please refer to the most recent annual information form and management discussion and analysis ("MD&A") of the Company for additional risk factors relating to Tamarack, which can be accessed either on Tamarack's website at www.tamarackvalley.ca or under the Company's profile on www.sedarplus.ca. The forward-looking statements contained in this news release 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 press release contains future-oriented financial information and financial outlook information (collectively, "FOFI") about Tamarack's annual guidance, net debt targets (and the reduction thereof), expected improvement in operating netbacks; expected operating netbacks, asset retirement obligations, and prospective results of operations and production, all of which are subject to the same assumptions, risk factors, limitations and qualifications as set forth in the above paragraphs and the assumptions outlined under "Specified Financial Measures" below, and should not be used for purposes other than those for which it is disclosed herein. Tamarack and its management believe that the prospective financial information 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, Tamarack's expected course of action. However, because this information is highly subjective, it should not be relied on as necessarily indicative of future activities or results.

The expected net debt target of $500 million in 2027 is based on the following assumptions: production of 68,000 - 73,000 boe per day, WTI price of US$65 per bbl, differentials of (US$13.25) per boe, (US$3.00) MSW, USD to CAD foreign exchange rate of 1.30 and shareholder returns of 60% of free cash flow, in-line with the Company's current return of capital framework.

Specified Financial Measures
This press release includes various specified financial measures, including non-IFRS financial measures, non-IFRS financial ratios, capital management measures and supplemental financial measures as further described herein. These measures do not have a standardized meaning prescribed by International Financial Reporting Standards ("IFRS") and, therefore, may not be comparable with the calculation of similar measures by other companies.

Field operating netbacks (non-IFRS financial measure) is calculated by subtracting royalty expenses, net operating expenses and transportation expenses from oil and natural gas sales. Tamarack and others utilize the Field Operating Netback measure to assess the operational performance of the Company's assets areas by isolating the impact of corporate and other overhead related expenditures. This metric is also presented on a per boe basis as a non-GAAP financial ratio.

Net production expenses (non-IFRS financial measure) is calculated by subtracting processing income from production expenses. Tamarack generates processing income from third parties that utilize excess capacity at Tamarack's facilities. Processing income is recognized as a reduction to production expenses, whereas processing income is reported as other income under GAAP. If Tamarack has excess capacity at one of its facilities, the Company will seek to process third-party volumes as a means to reduce the cost of operating those facilities. Accordingly, net production expenses allow Tamarack and others to assess the performance of its field and facility operating results by including the associated income generated from plant operations. Net production expenses are also presented on a per boe basis as a non-GAAP financial ratio.

Net debt (capital management measure) is determined by aggregating the Company's debt, government loans and other and current liabilities (net of current assets), excluding the current portion of commodity-based risk management contracts, asset retirement obligations and other liabilities. Tamarack and others utilize net debt to assess liquidity and balance sheet strength by aggregating select financial assets and financial liabilities on the Company's balance sheet.

Please refer to the Company's latest MD&A for additional information relating to specified financial measures including non-IFRS financial measures, non-IFRS financial ratios and capital management measures. The MD&A can be accessed either on Tamarack's website at www.tamarackvalley.ca or under the Company's profile on www.sedarplus.ca.
