NOT FOR DISTRIBUTION TO U.S. NEWS WIRE SERVICES OR DISSEMINATION IN THE UNITED STATES. ANY FAILURE TO COMPLY WITH THIS RESTRICTION MAY CONSTITUTE A VIOLATION OF U.S. SECURITIES LAW.

CALGARY, Alberta, March 05, 2021 (GLOBE NEWSWIRE) -- Tamarack Valley Energy Ltd. ("Tamarack" or the "Company") (TSX: TVE) is pleased to announce that it has entered into two separate agreements to acquire assets in the Provost and Nipisi areas of Alberta (the "Acquisitions"). The Acquisitions include approximately 2,800 boe/d of low decline (~16%) oil weighted assets under waterflood, along with approximately 38,400 net acres in the Clearwater play of Alberta (the “Assets”) for a total purchase price of approximately $135.3 million, net of proceeds from two newly created gross overriding royalties (“GORR”) on the Clearwater and Slave Point Nipisi assets, subject to certain closing adjustments. The completion of the Acquisitions is subject to customary regulatory approvals.

The Acquisitions will be funded through a $55.0 million bought deal equity financing, Tamarack's proforma credit facilities at closing of $325.0 million and $13.7 million in proceeds from the sale of the newly created GORR.

Brian Schmidt, President & CEO of Tamarack said “The Acquisitions supplement Tamarack's existing position in the Clearwater fairway and are consistent with our returns focused strategy to enhance the sustainability and resiliency of the Company’s free adjusted funds flow⁽¹⁾ profile with low decline oil production, long reserve life and economic oil weighted drilling inventory. Pro forma the Acquisitions and financing, Tamarack is well capitalized and strongly positioned to efficiently execute our development plan.”

Acquisition Highlights

• Increases Tamarack’s exposure to assets under waterflood and reduces corporate decline rate
  • Approximately 2,250 boe/d⁽²⁾ of Provost Sparky (“Eyehill”) low decline medium oil under waterflood with four (4.0 net) Sparky primary horizontal wells expected to be on production in March. Tamarack has identified 12 net primary and 29 net waterflood conversion patterns in the area. This medium oil asset is in close proximity to Tamarack’s existing Veteran assets and can benefit from operational efficiencies.
  • Approximately 500 boe/d⁽³⁾ of Nipisi Slave Point low decline light oil under waterflood and an additional 50 boe/d of Nipisi Clearwater oil⁽⁴⁾ with two additional Clearwater oil wells currently being brought on production and one well being drilled. Tamarack’s 15-24 Clearwater well, offsetting a portion of the acquired Clearwater lands, produced at an average rate of 278 bbl/d in the month of February.
  • Tamarack estimates that its pro forma 2021 corporate decline rate will be reduced to a range of 21 to 23%.

• Complements Tamarack’s Clearwater position in the Greater Nipisi area
  • 38,400 net acres of land in the Clearwater with 100 development locations over approximately 39 net sections along with 21 net sections of exploratory acreage.
  • Light oil production from the Slave Point provides an opportunity to realize further synergies through blending opportunities with the heavier oil production from the Clearwater
  • Internal assessments have identified a portion of the Nipisi Clearwater area as a focus for near term waterflood development due to the geological and oil fluid characteristics
• Enhances Tamarack’s free adjusted funds flow⁽⁵⁾ profile
  
  • Tamarack's pro forma 2021 guidance reflects a $20 million increase in free adjusted funds flow
  • Increased inventory of economic, low capital cost drilling inventory (~$1.0 to ~$1.2 million per well) in the Sparky and Clearwater oil plays
    
• Attractive metrics and positive environmental, social and governance (ESG) contributions
  
  • Existing production of ~2,800 boe/d has a low decline (~16%) and a significant oil and natural gas liquids (“NGL”) weighting (~86%)
  • Production base supports an annualized operating field netback⁽⁵⁾ of ~$35 million (~$35 per boe) and annualized free adjusted funds flow⁽⁵⁾ of $25 million
  • Attractive environmental asset profile with minimal asset retirement obligation (“ARO”) of $10.8MM (undiscounted, uninflated).

• Financing structure preserves Tamarack’s strong balance sheet
  • Equity financing and concurrent GORR disposition allows Tamarack to maintain significant liquidity under its expected proforma credit facilities of $325 million at closing
  • Pro forma the Acquisitions, Tamarack will maintain a strong 2021 year-end net debt to trailing annual adjusted funds flow ratio⁽⁵⁾ of less than 1.0x
    

Overview of the Acquisitions

Tamarack has entered into an asset purchase agreement with a publicly-traded oil and gas company (the “Vendor”), pursuant to which the Company will acquire the Vendor’s working interest in the Nipisi and Provost assets for cash consideration of $106 million with an effective date of February 1, 2021 (the “Asset Acquisition”).

Tamarack has signed a letter of intent and binding exclusivity agreement with Woodcote Petroleum Inc. (“Woodcote”) pursuant to which, subject to the execution of a definitive agreement, the Company will acquire all of the issued and outstanding shares of Woodcote, a private company with a 100% operated working interest in Greater Nipisi (the “Corporate Acquisition”) for aggregate consideration of $43 million comprised of $32 million in cash and $11 million in common shares to be issued at a deemed price of $ 2.25/share.

The Acquisitions are expected to close on or about March 25, 2021 subject to certain regulatory and other approvals and the satisfaction or waiver of customary closing conditions.

In conjunction with the Acquisitions, Tamarack has entered into two separate agreements to sell a gross overriding royalty (GORR) on the Clearwater and Slave Point Nipisi portion of the Assets for gross proceeds of $13.7 million.

Disclosure of Oil and Gas Information

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.

Reserves Disclosure. All reserves information in this press release relating to Assets are internally estimated by the Company’s' QRE effective March 1, 2021 in accordance with NI 51-101 and the COGEH. The estimates of reserves and future net revenue for the Acquisitions may not reflect the same confidence level as estimates of reserves and future net revenue for all of Tamarack's properties, due to the effects of aggregation.

All reserve references in this press release are "gross reserves". Gross reserves are a company's total working interest reserves before the deduction of any royalties payable by such company and before the consideration of such company's royalty interests. It should not be assumed that the present worth of estimated future cash flow of net revenue presented herein 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 Tamarack's crude oil, NGL and natural gas reserves, including those of the Assets, provided herein are estimates only and there is no guarantee that the estimated reserves will be recovered. Actual crude oil, natural gas and NGL reserves may be greater than or less than the estimates provided herein.

Drilling Locations. This press release discloses drilling locations with respect to the Assets in three categories: (i) proved locations; (ii) probable locations; and (iii) unbooked locations. Proved locations and probable locations are derived from the Company’s internal reserves evaluation as prepared by a member of management who is a qualified reserves evaluator in accordance with NI 51-101 effective March 3, 2021 and account for drilling locations that have associated proved and/or probable reserves, as applicable. Unbooked locations are internal estimates based on the Company's assumptions 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. Of the total 174 (166.6 net) drilling locations identified herein, 38 (35.3 net) are proved locations, eight (8.0 net) are probable locations and 128 (123.3 net) are unbooked locations. Of the 108 (105.5 net) locations specifically identified in the Nipisi area, all 108 (105.5 net) locations are unbooked. Unbooked locations have been identified by management as an estimation of Company's multi-year drilling activities based on evaluation of applicable geologic, seismic, engineering, production and reserves information assuming completion of the Acquisitions. Assuming completion of the Acquisitions, 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 the drilling of existing wells by the Vendor 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.

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: counterparty risk to closing the Acquisitions and the Offering; unforeseen difficulties in integrating the Assets into Tamarack's operations; incorrect assessments of the value of benefits to be obtained from acquisitions and exploration and development programs (including the Acquisitions); 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); commodity prices; the uncertainty of estimates and projections relating to production, cash generation, costs and expenses; health, safety, litigation and environmental risks; access to capital; and the COVID-19 pandemic. 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. Please refer to the annual information form for the year ended December 31, 2020 and management's discussion and analysis for the year ended December 31, 2020 (the "MD&A") 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.sedar.com.The forward-looking statements contained in this press 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 prospective results of operations and production, weightings, operating costs, expenditures, decline rates, operating field netbacks, future development capital, abandonment and reclamation obligations, capital budgets, adjusted funds flow, free adjusted funds flow, net, net debt to trailing adjusted funds flow and components thereof, 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 document was approved by management as of the date of this document and was provided for the purpose of providing further information about Tamarack's future business operations. Tamarack disclaims any intention or obligation to update or revise any FOFI contained in this document, 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 document should not be used for purposes other than for which it is disclosed herein.

References in this press release to 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 Tamarack.

Non-IFRS Measures

Certain measures commonly used in the oil and natural gas industry referred to herein, including, "operating field netback", "adjusted funds flow", "free adjusted funds flow", "net debt" and "net debt to trailing adjusted funds flow", do not have a standardized meaning prescribed by IFRS and therefore may not be comparable with the calculation of similar measures by other companies. These non-IFRS measures are further described and defined below. Such non-IFRS measures are not intended to represent operating profits nor should they be viewed as an alternative to cash flow provided by operating activities, net earnings or other measures of financial performance calculated in accordance with IFRS.

Operating Field Netback

"Operating Field Netback" equals total petroleum and natural gas sales, less royalties and net production and transportation expenses.

Management uses certain industry benchmarks, such as Operating field netback, to analyze financial and operating performance. This metric can also be calculated on a per boe basis. Management considers Operating Field Netback an important measure to evaluate Tamarack's operational performance, as it demonstrates field level profitability relative to current commodity prices.

Operating Field Netbacks in this press release are based on a WTI price of US$57.50/bbl, a MSW/WTI differential of US$4.25/bbl, a WSC/WTI differential of US$12.00/bbl, an AECO price of $2.70/GJ and a USD/CAD exchange rate of $1.27.

The Operating Field Netback ($/boe) assumptions used for the Assets in 2021 are as follows:

Adjusted Funds Flow and Free Adjusted Funds Flow

"Adjusted Funds Flow" is calculated by taking cash-flow from operating activities and adding back changes in non-cash working capital and expenditures on decommissioning obligations, since Tamarack believes the timing of collection, payment or incurrence of these items is variable. Expenditures on decommissioning obligations may vary from period to period depending on capital programs and the maturity of the Company's operating areas. Expenditures on decommissioning obligations are managed through the capital budgeting process which considers available Adjusted Funds Flow. Tamarack uses Adjusted Funds Flow as a key measure to demonstrate the Company's ability to generate funds to repay debt and fund future capital investment. Adjusted Funds Flow can also be calculated on a per boe basis. Adjusted Funds Flow per share is calculated using the same weighted average basic and diluted shares that are used in calculating income (loss) per share.

"Free Adjusted Funds Flow" is calculated by taking Adjusted Funds Flow and subtracting capital expenditures, excluding acquisitions and dispositions. Management believes that Free Adjusted Funds Flow provides a useful measure to determine Tamarack's ability to improve returns and to manage the long-term value of the business.

Net Debt and Related Measures

"Net Debt" is calculated as bank debt plus working capital surplus or deficit, including the fair value of cross-currency swaps and excluding the fair value of financial instruments and lease liabilities.

"Year-End Net Debt to Trailing Annual Adjusted Funds Flow" is calculated as estimated year-end Net Debt divided by the estimated Adjusted Funds Flow for the four preceding quarters at year-end.

Tamarack closely monitors its capital structure with a goal of maintaining a strong balance sheet to fund the future growth of the Company. The Company monitors Net Debt as part of its capital structure. The Company uses Net Debt as an alternative measure of outstanding debt. Management considers Net Debt an important measure to assist in assessing the liquidity of the Company.

Oil and Gas Metrics

"Future Development Capital" means the expected aggregate exploration and development costs incurred in a financial year on reserves that are categorized as development. Future Development Capital presented herein excludes land and capitalized administration costs but includes the cost of acquisitions and capital associated with acquisitions where reserve additions are attributed to the acquisitions.

"Reserve Life Index" or "RLI" is calculated by dividing reserves volumes by estimated production. RLIs are not necessarily comparable between different issues as there may be variation in calculation methodology. Management views RLI as a useful measure of the length of time the reserves would be produced at the estimated rate of production.

Please refer to the MD&A for additional information relating to Non-IFRS measures. The MD&A can be accessed either on Tamarack's website at www.tamarackvalley.ca or under the Company's profile on www.sedar.com.
