Financial & Operating Highlights

Liquidity and Financial Position

Full-year 2025 and Q4 2025 Review

Greenfire’s 2025 annual production averaged 16,169 bbls/d, slightly exceeding the Company’s outlook of 15,000–16,000 bbls/d. Capital expenditures for 2025 totaled $111.8 million, below the outlook of $130 million, partly due to the deferral of approximately $9 million in spending for the Pad 7 program at the Expansion Asset into early 2026, which remains on schedule.

Greenfire’s average production for Q4 2025 was 15,699 bbls/d, similar to the 15,757 bbls/d reported in Q3 2025.

Hangingstone Facilities: Bitumen Production Results

Operational Update and 2026 Outlook

Production and Steam Generation Updates: Greenfire’s average production for January and February 2026 was approximately 15,440 bbls/d and 14,330 bbls/d, respectively. While production from the Demo Asset has exceeded expectations year-to-date due to continued optimization of base well performance, production from the Expansion Asset is currently below the Company’s projections, principally due to unplanned downtime associated with a highly productive well. This well has since been redrilled and is scheduled to be back online in March 2026. Regarding the previously disclosed refurbishment of the second steam generator at the Expansion Asset, this project was successfully completed at year-end 2025.

Regulatory Engagement and Installation of Sulphur Removal Facilities: In Q4 2025, Greenfire completed the installation and commissioning of sulphur removal facilities at the Expansion Asset. These facilities are now fully operational, and the Company has restored compliance with regulatory limits for sulphur dioxide emissions.

2026 Outlook: In light of the unplanned well downtime at the Expansion Asset during the first quarter of 2026, in conjunction with slightly steeper-than-anticipated base production decline rates, Greenfire is lowering its 2026 production guidance to a range of 13,500–15,500 bbls/d (previously 15,500–16,500 bbls/d). As previously publicized, the Expansion Asset has been historically undercapitalized with no new well-pairs drilled at the asset since 2017, resulting in the existing base production well-pairs approaching higher recovery factors. Encouragingly, Greenfire has budgeted for 25 new well-pairs across three new SAGD pads (discussed below) to be spud over the following 12 months, and the recent late-life base production challenges at the Expansion Asset bear no impact on the estimated production performance of our growth capital program.

Corporate Updates

Management Changes:

Rights Offering and 2028 Notes Redemption Completed: Greenfire completed its previously disclosed refinancing initiatives on December 19, 2025, which included the issuance of approximately 55.1 million common shares under a rights offering (the “Rights Offering”) for gross proceeds of $298.7 million. Certain limited partnerships comprising Waterous Energy Fund (“WEF”) provided a standby commitment to backstop the Rights Offering by agreeing to acquire any common shares not subscribed for under the Rights Offering. The standby commitment was not utilized as the Rights Offering was oversubscribed. WEF did not receive any compensation in connection with the standby commitment. Followng completion of the Rights Offering and using net proceeds of the Rights Offering and cash on hand, the Company redeemed all of its outstanding 12.00% senior secured notes due 2028 on December 19, 2025. Greenfire is currently debt-free and maintains an undrawn $275 million senior revolving credit facility.

OIL AND GAS METRICS

This press release contains certain oil and gas metrics, which do not have standardized meanings or standard methods of calculation and therefore such measures may not be comparable to similar measures used by other companies and should not be used to make comparisons. Such metrics have been included herein to provide readers with additional measures to evaluate Greenfire’s performance; however, such measures are not reliable indicators of the future performance and future performance may not compare to the performance in previous periods and therefore such metrics should not be unduly relied upon.

Greenfire’s reserve life index is calculated using Greenfire’s total gross reserves (either on a 1P or 2P basis) and dividing them by management’s current anticipated 2025 production. The reserve life index is used by management to assess the longevity of the reserves.

Net asset value (or NAV) after adjusting for net surplus is calculated using the estimated after-tax net present value of the respective reserves category, discounted at 10%, plus the Company’s net surplus at year-end 2025, divided by shares outstanding at year-end 2025.

Non-GAAP and Supplementary Financial Measures

Certain financial measures in this press release are non-GAAP financial measures or ratios. These measures do not have a standardized meaning under IFRS Accounting Standards and therefore may not be comparable to similar measures provided by other companies. These non-GAAP measures should not be considered in isolation or as an alternative for measures of performance prepared in accordance with IFRS Accounting Standards. This press release also contains supplementary financial measures.

Non-GAAP financial measures and ratios include operating netback, adjusted funds flow, adjusted free cash flow, net surplus (debt), available funding, and per barrel figures associated with such non-GAAP financial measures. Supplementary financial measures and ratios include gross profit, capital expenditures, and depletion.

Non-GAAP Financial Measures

Operating Netback (including per barrel ($/bbl)) Gross profit (loss) is the most directly comparable GAAP measure to operating netback which is a non-GAAP measure. Operating netback is comprised of gross profit (loss), plus loss on risk management contracts, less gain on risk management contracts and plus depletion expense on the Company’s operating assets, and is further adjusted for realized gain (loss) on risk management contracts, as appropriate. Operating netback per barrel ($/bbl) is calculated by dividing operating netback by the Company’s total bitumen sales volume in a specified period. When Operating netback is expressed on a per barrel basis, it is a non-GAAP ratio. Operating netback is a financial measure widely used in the oil and gas industry as a supplementary measure of a company’s efficiency and ability to generate cash flow for debt repayments, capital expenditures, or other uses.

The following table is a reconciliation of gross profit (loss) to operating netback:

Adjusted Funds Flow and Adjusted Free Cash Flow

Cash provided by operating activities is the most directly comparable GAAP measure for adjusted funds flow, which is a non-GAAP measure. This measure is not intended to represent cash provided by operating activities calculated in accordance with IFRS Accounting Standards.

The adjusted funds flow measure allows management and others to evaluate the Company’s ability to fund its capital programs and meet its ongoing financial obligations using cash flow internally generated from ongoing operating related activities. We compute adjusted funds flow as cash provided by operating activities, excluding the impact of changes in non-cash working capital, less transaction costs and transactions considered non-recurring in nature or outside of normal business operations.

Cash provided by operating activities is the most directly comparable GAAP measure for adjusted free cash flow, which is a non-GAAP measure. Management uses adjusted free cash flow as an indicator of the efficiency and liquidity of its business, measuring its funds after capital investment that are available to manage debt levels and return capital to shareholders. By removing the impact of current period property, plant and equipment expenditures from adjusted free cash flow, management monitors its adjusted free cash flow to inform its capital allocation decisions. We compute adjusted free cash flow as cash provided by operating activities, excluding the impact of changes in non-cash working capital, less transaction costs, transactions considered non-recurring in nature or outside of normal business operations, property, plant and equipment expenditures and acquisition costs.

The following table is a reconciliation of cash provided by operating activities to adjusted funds flow and adjusted free cashflow:

Net Surplus (Debt)

The table below reconciles long-term debt to net surplus (debt).

Net surplus (debt) is a non-GAAP measure. Long-term debt is a GAAP measure that is the most directly comparable financial statement measure to net surplus (debt). Net surplus (debt) is computed as the face value of Greenfire’s long-term debt adjusted for accounts payable and accrued liabilities, cash and cash equivalents, accounts receivable, inventories, and prepaids expenses and deposits. Management uses net surplus (debt) to monitor and evaluate the Company’s financial strength, and financing requirements.

Available Funding

Net working capital surplus (deficit) is the GAAP measure that is the most directly comparable measure to available funding. Available funding is calculated as working capital surplus (deficit), adjusted to exclude the current portion of risk management contracts, lease liabilities and other, current portion of decommissioning obligations, warrant liabilities, and the current portion of long-term debt, and including the undrawn capacity available under the Company’s Senior Credit Facility. Management uses available funding to assess liquidity, financial flexibility and the Company’s ability to fund capital expenditures, and other obligations as they come due.

Supplementary Financial Measures

Depletion

The term “depletion” or “depletion expense” is the portion of depletion and depreciation expense reflecting the cost of development and extraction of the Company’s bitumen reserves.

Gross Profit (Loss)

Gross profit (loss) is a supplementary financial measure prepared on a consistent basis with IFRS Accounting Standards. Greenfire uses gross profit (loss) to assess its core operating performance before considering other expenses such as general and administrative costs, financing costs, and income taxes. Gross profit (loss) is calculated as oil sales, net of royalties, plus gains on risk management contracts, less losses on risk management contracts, diluent expense, operating expense, depletion expense on the Company’s operating assets, transportation expenses and marketing expenses.

Management believes that gross profit (loss) provides investors, analysts, and other stakeholders with useful insight into the Company’s ability to generate profitability from its core operations before non-operating expenses.

Capital Expenditures

Capital expenditures is a supplementary financial measure prepared on a consistent basis with IFRS Accounting Standards. Greenfire uses capital expenditures to monitor the cash flows it invests into property, plant and equipment. Capital expenditures is derived from the statement of cash flows and includes property, plant and equipment expenditures and acquisitions.

Management believes that capital expenditures provides investors, analysts and other stakeholders with a useful insight into the Company’s investments into property, plant and equipment.
