⁽¹⁾	Fund flows from operations (FFO) is a total of segments and non-GAAP financial measure most directly comparable to net loss and is calculated as sales less royalties, transportation expense, operating expense, G&A expense, corporate income tax expense (recovery), PRRT expense, interest expense, equity based compensation settled in cash, realized (gain) loss on derivatives, realized foreign exchange (gain) loss, and realized other (income) expense. The measure is used by management to assess the contribution of each business unit to Vermilion's ability to generate income necessary to pay dividends, repay debt, fund asset retirement obligations, and make capital investments. FFO does not have a standardized meaning under IFRS® Accounting Standards and therefore may not be comparable to similar measures provided by other issuers. More information and a reconciliation to net earnings (loss), the most directly comparable primary financial statement measure, can be found in the "Non-GAAP and Other Specified Financial Measures" section of this document. Fund flows from continuing operations and fund flows from discontinued operations are calculated in the same manner as FFO and are most directly comparable to net earnings (loss) from continuing operations and net earnings (loss) discontinued operations, respectively.

⁽²⁾	Fund flows from operations per basic share and diluted share is calculated by dividing fund flows from operations (total of segments and non-GAAP financial measure) by the basic weighted average shares outstanding as defined under IFRS Accounting Standards. Fund flows from operations per diluted share is calculated by dividing fund flows from operations by the sum of basic weighted average shares outstanding and incremental shares issuable under the equity based compensation plans as determined using the treasury stock method. Management assesses fund flows from operations on a per share basis as we believe this provides a measure of our operating performance after taking into account the issuance and potential future issuance of Vermilion common shares. More information and a reconciliation to cash flows used in investing activities, the most directly comparable primary financial statement measure, can be found in the "Non-GAAP and Other Specified Financial Measures" section of this document. Fund flows from continuing operations per basic and diluted share and fund flows from discontinued operations per basic and diluted share are calculated in the same manner as FFO per basic and diluted share.

⁽³⁾	Capital expenditures is a non-GAAP financial measure most directly comparable to cash flows used in investing activities and is calculated as the sum of drilling and development costs and exploration and evaluation costs. Management considers capital expenditures to be a useful measure of our investment in our existing asset base. Capital expenditures does not have a standardized meaning under IFRS Accounting Standards and therefore may not be comparable to similar measures provided by other issuers. More information and a reconciliation to cash flows used in investing activities, the most directly comparable primary financial statement measure, can be found in the "Non-GAAP and Other Specified Financial Measures" section of this document. Capital expenditures is also referred to as E&D capital expenditures.

⁽⁴⁾	Acquisitions is a non-GAAP financial measure and is not a standardized financial measure under IFRS Accounting Standards and therefore may not be comparable to similar measures disclosed by other issuers. Acquisitions is calculated as the sum of acquisitions, net of cash acquired, acquisitions of securities and net acquired working capital (deficit). Management believes that including these components provides a useful measure of the economic investment associated with our acquisition activity and is most directly comparable to cash flows used in investing activities. More information and a reconciliation to acquisitions, net of cash acquired and acquisition of securities, the most directly comparable primary financial statement measure, can be found in the "Non-GAAP and Other Specified Financial Measures" section of this document.

⁽⁵⁾	Dispositions is a non-GAAP financial measure and is not a standardized financial measure under IFRS Accounting Standards and therefore may not be comparable to similar measures disclosed by other issuers. Dispositions is calculated as the sum of dispositions, and disposition of securities. Management believes that including these components provides a useful measure of the proceeds associated with our disposition activities and is most directly comparable to cash flows used in investing activities. More information and a reconciliation to dispositions and disposition of securities, the most directly comparable primary financial statement measures, can be found in the "Non-GAAP and Other Specified Financial Measures" section of this document.

⁽⁶⁾	Free cash flow (FCF) and excess free cash flow (EFCF) are non-GAAP financial measures most directly comparable to cash flows from operating activities. FCF is calculated as FFO less drilling and development costs and exploration and evaluation costs and EFCF is calculated as FCF less payments on lease obligations and asset retirement obligations settled. FCF is used by management to determine the funding available for investing and financing activities including payment of dividends, repayment of long-term debt, reallocation into existing business units and deployment into new ventures. EFCF is used by management to determine the funding available to return to shareholders after costs attributable to normal business operations. FCF and EFCF do not have standardized meanings under IFRS Accounting Standards and therefore may not be comparable to similar measures provided by other issuers. More information and a reconciliation to cash flows from operating activities, the most directly comparable primary financial statement measure, can be found in the "Non-GAAP and Other Specified Financial Measures" section of this document.
⁽⁷⁾	Net debt is a capital management measure in accordance with IAS 1 "Presentation of Financial Statements" that is most directly comparable to long-term debt and is calculated as long-term debt (excluding unrealized foreign exchange on swapped USD borrowings) plus adjusted working deficit (capital), a non-GAAP financial measure described in the "Non-GAAP and Other Specified Financial Measures" section of this document. Management considers this a helpful representation of Vermilion's net financing obligations after adjusting for the timing of working capital fluctuations. More information and a reconciliation to long-term debt, the most directly comparable primary financial statement measure, can be found in the "Non-GAAP and Other Specified Financial Measures" section of this document.

⁽⁸⁾	Net debt to four quarter trailing fund flows from operations is a non-GAAP ratio and is not a standardized financial measure under IFRS Accounting Standards and therefore may not be comparable to similar measures disclosed by other issuers. Net debt to four quarter FFO is calculated as net debt divided by FFO from the preceding four quarters. Management uses this measure to assess the Company's ability to repay debt. More information can be found in the "Non-GAAP and Other Specified Financial Measures" section of this document.

	Subsequent to February 26, 2025, net debt to four quarter trailing fund flows from operations is calculated inclusive of Westbrick Energy's pre-acquisition four quarter trailing fund flows from operations, as if the acquisition of Westbrick Energy occurred at the beginning of the four quarter trailing period, and exclusive of the four quarter trailing fund flows from discontinued operations to reflect the Company's ability to repay debt on a pro forma basis.

⁽⁹⁾	Diluted shares outstanding represents the sum of shares outstanding at the period end plus outstanding awards under the Long-term Incentive Plan, based on current estimates of future performance factors and forfeiture rates.

⁽¹⁰⁾	Please refer to Supplemental Table 4 "Production" of the accompanying Management's Discussion and Analysis for disclosure by product type.

⁽¹¹⁾	Operating netback is a non-GAAP financial measure that is not standardized under IFRS Accounting Standards and may not be comparable to similar measures disclosed by other issuers. Operating netback is most directly comparable to net (loss) earnings and is calculated as sales less royalties, operating expense, transportation expense, PRRT expense, and realized hedging (gain) loss, and when presented on a per unit basis is a non-GAAP ratio. Management assesses operating netback as a measure of the profitability and efficiency of our field operations. More information and a reconciliation to net (loss) earnings, the most directly comparable primary financial statement measure, can be found in the "Non-GAAP and Other Specified Financial Measures" section of this document.

⁽¹²⁾	Fund flows from operations per boe is a non-GAAP ratio that is not standardized under IFRS Accounting Standards and may not be comparable to similar measures disclosed by other issuers. FFO per boe is calculated as FFO divided by boe production. FFO per boe is used by management to assess the profitability of Vermilion's business units and Vermilion as a whole. More information can be found in the "Non-GAAP and Other Specified Financial Measures" section of this document. Fund flows from continuing operations per boe and fund flows from discontinued operations per boe are calculated in the same manner as FFO per boe.

⁽¹³⁾	Estimated gross proved, developed and producing, total proved, and total proved plus probable reserves as evaluated by McDaniel & Associates Consultants Ltd. ("McDaniel") in a report dated March 3, 2026 with an effective date of December 31, 2025 (the "McDaniel Reserves Report"). See Vermilion's annual information form for the year ended December 31, 2025 for additional information, including reserve pricing assumptions. Per share metrics calculated using basic shares outstanding at December 31, 2025.

⁽¹⁴⁾	F&D (finding and development) and FD&A (finding, development and acquisition) costs are calculated by dividing the applicable capital expenditures for the period, including the change in undiscounted FDC (future development capital), by the change in the reserves, incorporating revisions and production, for the same period. More information can be found in the "Non-GAAP Financial Measures and Other Specified Financial Measures" section of this document.

⁽¹⁵⁾	Operating Recycle Ratio is a non-GAAP ratio that is calculated by dividing the Operating Netback, excluding PRRT and realized hedging gains and losses, by the cost of adding reserves (F&D and FD&A cost). For the purposes of calculating 2025 Operating Recycle Ratio, this netback number was $26.60. More information can be found in the "Non-GAAP Financial Measures and Other Specified Financial Measures" section of this document.

Q4 2025 Results

Outlook

Message to Shareholders

It was an impactful year for Vermilion, repositioning the Company as a Global Gas Producer with long-duration assets, improving profitability and growing free cash flow ("FCF") per share. Through the acquisition of Westbrick Energy Ltd. and the divestments of our Saskatchewan and United States businesses, our go-forward strategy is focused on our gas-weighted assets in Canada and Europe. Our portfolio is anchored by liquids–rich gas assets in the Deep Basin and Montney, complemented by premium-priced European gas assets in Germany, Ireland and the Netherlands. This exposure to global commodity prices remains a strategic advantage for Vermilion, as illustrated by our 2025 realized gas price, after hedging, of $6.01/mcf, which benefits from direct exposure to European gas prices. Europe is on track to exit the winter season with gas inventories well below the five-year average, and the requirement to refill storage ahead of the next winter season is expected to be positive to gas fundamentals.

Our repositioned global gas portfolio is characterized by higher production per share and a lower cost structure, the combination of which delivers growing FCF – all underpinned by high-quality, long-life assets. Through acquisitions and exploration, we have secured large in-place resource that provides decades of development opportunities. We continue to improve on controllable elements of our business – including safety, production and costs – driving stronger profitability. Our strategic investments in Mica Montney infrastructure to achieve our target production of 28,000 boe/d, while leveraging existing Deep Basin infrastructure to profitably grow production, along with development of an existing large gas discovery in Germany, will deliver a sustainable increase in excess free cash flow ("EFCF"). The long duration of our asset base and our commitment to disciplined capital allocation, combined with a low share count, benefits our shareholders through enhanced per share outcomes. With fewer than 153 million shares outstanding, Vermilion is well positioned to add meaningful per-share value as we execute on our strategic objectives.

Vermilion has a clear strategic roadmap to 2030, with a significant increase in FCF anticipated in 2028, as outlined in our recent Investor Day, which utilized a flat commodity price assumption. The roadmap underscores the depth and quality of Vermilion's portfolio well beyond 2030 and reinforces our conviction in the Company's long–term value proposition.

Our long-term execution is driven by our focus on what we can control. Through a busy year of acquisition and divestiture activity, Vermilion delivered strong operational and financial performance, with Q4 2025 representing another solid quarter. Production in Q4 2025 exceeded the top end of our guidance range, while fund flows from operations ("FFO") benefitted from strong realized pricing and an improved cost structure. In the Deep Basin, we brought online some of the strongest gas wells in Alberta, which reinforces our confidence in the quality of our assets and our 2026 drilling program. Our Mica Montney asset achieved record quarterly production and successfully delineated additional acreage on the Alberta side of our asset. Global gas sales in Q4 2025 continued to benefit from strong realizations, with a realized price, after hedging, of $5.50/mcf, more than doubling the AECO benchmark for the quarter. Vermilion's direct European gas exposure, over 110 mmcf/d in Q4 2025, is a significant driver of this outperformance, while our Canadian gas production benefitted from enhanced market diversification and a sophisticated hedging program to exceed local benchmark prices.

We are encouraged by Vermilion's recent performance and are excited about the outlook we shared at Investor Day. We remain focused on improving profitability and resilience across the business. With a high-quality asset base and a strong team in place, we are confident in our ability to grow FCF, reduce net debt, and return capital to shareholders – and in our ability to maintain this performance for many years to come.

Q4 2025 Review

Vermilion generated $241 million of FFO in Q4 2025, with FCF of $49 million on E&D capital expenditures of $192 million. During the quarter, the Company recorded non-cash, price-related impairment charges related to legacy mature assets in Australia, France and Ireland. These price-related impairments on legacy mature assets are not an indication of deterioration in the performance or outlook of Vermilion's mature asset portfolio. With respect to Ireland, the $304 million non-cash impairment represents a partial reversal of the price-driven $439 million non-cash gain on acquisition recorded in 2023 in Ireland, based upon lower European gas prices.

Production averaged 121,308 boe/d (69% natural gas)⁽¹⁾⁽¹⁾⁽¹⁾⁽¹⁾

In Canada, the Company maintained a three-rig drilling program in the Deep Basin, drilling sixteen (16.0 net), completing fourteen (14.0 net), and bringing on production seventeen (17.0 net) liquids-rich gas wells. The Company elected to defer start-up of several highly productive wells that were drilled and completed in Q3 2025 to mid-Q4 2025 to maximize profitability. With these wells coming on production in the quarter, as well as previously shut-in wells being brought back online, production from continuing operations in Canada was over 5,000 boe/d higher than the prior quarter. In addition to record Q4 production in the Montney, we drilled four (4.0 net) liquids-rich shale gas wells that are expected to be completed and brought online in 2026.

In the Netherlands, Vermilion completed and brought on production two (1.2 net) conventional natural gas wells in Q4 2025. The Company also progressed preliminary work to facilitate drilling one (0.5 net) well in Netherlands in 2026, including receiving certain required permits. In Germany, we progressed infrastructure build-out for the first Wisselshorst well (0.6 net) during Q4 2025 and we expect first production from this well in mid-2026. In addition, the Osterheide well (1.0 net) that was brought on production earlier in the year increased production in Q4 2025, with average production of 10 mmcf/d (1,600 boe/d) up 45% compared to the prior quarter.

Operationally, the fourth quarter of 2025 was reflective of our focus on continuous improvement. In Canada, our greater operational scale, high-quality assets and commitment to cost management drove unit operating costs to their lowest level in over a decade. On a corporate basis, this resulted in unit operating costs of $11.86, the lowest since 2020.

During the fourth quarter of 2025, we accelerated debt reduction by selling a portion of our ownership of Coelacanth Energy Inc. ("Coelacanth"). The transactions, completed in December 2025, resulted in $42MM of incremental debt reduction and a realized gain on disposition of $12 million. We continue to hold a 10.1% ownership in Coelacanth and will continue to monitor delineation activity on the Coelacanth asset base.

2025 Reserves Update

Vermilion's reserves are evaluated by the Company's independent qualified reserves evaluator. Total proved developed producing ("PDP") reserves increased by 25% from the prior year to 210 mmboe⁽²⁾⁽²⁾⁽³⁾⁽⁴⁾

The 2P reserve life index at December 31, 2025, is 14 years, which is consistent with our long-term average. Vermilion's internal estimate of drilling locations across our 1.3 million net acres in the Deep Basin and Montney is approximately 1,700 locations⁽⁵⁾⁽²⁾⁽²⁾

The following table provides a summary of company interest reserves by reserve category and region on an oil equivalent basis. Please refer to Vermilion's 2025 Annual Information Form for the year ended December 31, 2025 ("2025 Annual Information Form") for detailed information by country and product type.

Outlook and Guidance Update

Vermilion expects Q1 2026 production to average 122,000 to 124,000 boe/d (70% natural gas)⁽⁶⁾

Full-year 2026 guidance is unchanged, with the Company expecting to deliver production of 118,000 to 122,000 boe/d (70% gas)⁽⁶⁾

Commodity Hedging

Vermilion hedges to manage commodity price exposures and increase the stability of our cash flows. In aggregate, we have 48% of our expected net-of-royalty production hedged for 2026. With respect to individual commodity products, we have hedged 50% of our European natural gas production, 53% of our crude oil production, and 45% of our North American natural gas volumes, respectively.

Non-GAAP and Other Specified Financial Measures

This report and other materials released by Vermilion includes financial measures that are not standardized, specified, defined, or determined under IFRS Accounting Standards and are therefore considered non-GAAP or other specified financial measures and may not be comparable to similar measures presented by other issuers. These financial measures include:

Total of Segments Measures

Most directly comparable to net loss, FFO is a non-GAAP financial measure and total of segments measure comprised of sales less royalties, transportation, operating, G&A, corporate income tax, PRRT, interest expense, equity based compensation settled in cash, realized gain (loss) on derivatives, realized foreign exchange gain (loss), and realized other income (expense). The measure is used by management to assess the contribution of each business unit to Vermilion's ability to generate income necessary to pay dividends, repay debt, fund asset retirement obligations and make capital investments. Reconciliation to the most directly comparable primary financial statement measures can be found below. Fund flows from continuing operations and fund flows from discontinued operations are calculated in the same manner as FFO and is most directly comparable to net earnings (loss) from continuing operations and net earnings (loss) discontinued operations, respectively.Fund flows from operations (FFO):

Reconciliation of fund flows from continuing operations to net loss from continuing operations:

Reconciliation of fund flows from discontinued operations to net earnings (loss) from discontinued operations:

Non-GAAP Financial Measures and Non-GAAP Ratios

FFO per basic share and diluted share are non-GAAP ratios. Management assesses fund flows from operations on a per share basis as we believe this provides a measure of our operating performance after taking into account the issuance and potential future issuance of Vermilion common shares. Fund flows from operations per basic share is calculated by dividing fund flows from operations (total of segments measure) by the basic weighted average shares outstanding as defined under IFRS Accounting Standards. Fund flows from operations per diluted share is calculated by dividing fund flows from operations by the sum of basic weighted average shares outstanding and incremental shares issuable under the equity based compensation plans as determined using the treasury stock method. Fund flows from continuing operations per basic and diluted share and fund flows from discontinued operations per basic and diluted share are calculated in the same manner as FFO per basic and diluted share.Fund flows from operations per basic and diluted share:

Management uses fund flows from operations per boe to assess the profitability of our business units and Vermilion as a whole. Fund flows from operations per boe is calculated by dividing fund flows from operations (total of segments measure) by boe production. Fund flows from continuing operations per boe and fund flows from discontinued operations per boe are calculated in the same manner as FFO per boe.Fund flows from operations per boe:

Most directly comparable to cash flows from operating activities, FCF is a non-GAAP financial measure calculated as fund flows from operations less drilling and development costs and exploration and evaluation costs and EFCF is comprised of FCF less payments on lease obligations and asset retirement obligations settled. FCF is used by management to determine the funding available for investing and financing activities including payment of dividends, repayment of long-term debt, reallocation into existing business units and deployment into new ventures. EFCF is used by management to determine the funding available to return to shareholders after costs attributable to normal business operations. Reconciliation to the primary financial statement measures can be found in the following table.Free cash flow (FCF) and excess free cash flow (EFCF):

Most directly comparable to cash flows used in investing activities, capital expenditures is a non-GAAP financial measure calculated as the sum of drilling and development costs and exploration and evaluation costs as derived from the Consolidated Statements of Cash Flows. We consider capital expenditures to be a useful measure of our investment in our existing asset base. Capital expenditures are also referred to as E&D capital. Reconciliation to the primary financial statement measures can be found below.Capital expenditures:

Payout and payout % of FFO are, respectively, a non-GAAP financial measure and non-GAAP ratio. Payout is most directly comparable to dividends declared. Payout is comprised of dividends declared plus drilling and development costs, exploration and evaluation costs, and asset retirement obligations settled, and payout % of FFO is calculated as payout divided by FFO. The measure is used by management to assess the amount of cash distributed back to shareholders and reinvested in the business for maintaining production and organic growth. Payout as a percentage of FFO is also referred to as the payout ratio or sustainability ratio. The reconciliation of the measure to the primary financial statement measure can be found below.Payout and payout % of FFO:

ROCE is a measure that management uses to analyze our profitability and the efficiency of our capital allocation process; the comparable primary financial statement measure is earnings before income taxes. ROCE is calculated by dividing net loss before interest and taxes ("EBIT") by average capital employed over the preceding twelve months. Capital employed is calculated as total assets less current liabilities while average capital employed is calculated using the balance sheets at the beginning and end of the twelve-month period.Return on capital employed (ROCE):,

Average capital employed includes the current portion of asset retirement obligations, previously presented on a combined basis as long-term. The prior period results have been presented to conform with current period presentation.⁽¹⁾

Adjusted working capital (deficit) is a non-GAAP financial measure calculated as current assets less current liabilities, excluding current derivatives, current asset retirement obligations and current lease liabilities. The measure is used by management to calculate net debt, a capital management measure disclosed below.Adjusted working capital (deficit):

Asset retirement obligations previously presented as a combined balance have been reclassified into current and long-term portion of asset retirement obligations. The prior period results have been presented to conform with current period presentation.⁽¹⁾

Acquisitions is a non-GAAP financial measure and is calculated as the sum of acquisitions, net of cash acquired and acquisitions of securities from the Consolidated Statements of Cash Flows, Vermilion common shares issued as consideration, the estimated value of contingent consideration, the amount of acquiree's outstanding long-term debt assumed, and net acquired working capital deficit or surplus. Management believes that including these components provides a useful measure of the economic investment associated with our acquisition activity and is most directly comparable to cash flows used in investing activities. A reconciliation to the acquisitions line items in the Consolidated Statements of Cash Flows can be found below.Acquisitions:

Dispositions is a non-GAAP financial measure and is calculated as the sum of dispositions, and disposition of securities from the Consolidated Statements of Cash Flows. Management believes that including these components provides a useful measure of the proceeds associated with our disposition activities and is most directly comparable to cash flows used in investing activities. A reconciliation to dispositions, and disposition of securities, the most directly comparable primary financial statement measures, can be found below.Dispositions:

Operating netback is non-GAAP financial measure and is calculated as sales less royalties, operating expense, transportation costs, PRRT, and realized hedging gains and losses, and when presented on a per unit basis is a non-GAAP ratio. Operating netback is most directly comparable to net loss. Management assesses operating netback as a measure of the profitability and efficiency of our field operations.Operating netback:

Management uses net debt (a capital management measure, as defined below) to four quarter trailing fund flows from operations to assess the Company's ability to repay debt. Net debt to four quarter trailing fund flows from operations is a non-GAAP ratio calculated as net debt (capital management measure) divided by fund flows from operations (total of segments measure) from the preceding four quarters.Net debt to four quarter trailing fund flows from operations:

Capital Management Measure

Net debt is a capital management measure in accordance with IAS 1 "Presentation of Financial Statements" that is most directly comparable to long-term debt. Net debt is comprised of long-term debt (excluding unrealized foreign exchange on swapped USD borrowings) plus adjusted working capital (defined as current assets less current liabilities, excluding current derivatives, current asset retirement obligations and current lease liabilities), and represents Vermilion's net financing obligations after adjusting for the timing of working capital fluctuations.Net debt:

Adjusted working capital is defined as current assets (excluding current derivatives), less current liabilities (excluding current derivatives, current asset retirement obligations and current lease liabilities).⁽¹⁾

Vermilion may enter into cross currency interest rate swaps to hedge the foreign exchange movements on USD borrowings on our revolving credit facility. Unrealized FX on swapped USD borrowings relates to the unrealized gains and losses on our cross currency interest swaps. At December 31, 2025, there was $196.7 million of USD borrowings on our revolving credit facility. (December 31, 2024 - $nil).⁽²⁾

Subsequent to February 26, 2025, net debt to four quarter trailing fund flows from operations is calculated inclusive of Westbrick Energy's pre-acquisition four quarter trailing fund flows from operations, as if the acquisition of Westbrick Energy occurred at the beginning of the four quarter trailing period, and exclusive of the four quarter trailing fund flows from discontinued operations to reflect the Company's ability to repay debt on a pro forma basis.⁽³⁾

Supplementary Financial Measures

The sum of shares outstanding at the period end plus outstanding awards under the Long-term Incentive Plan ("LTIP"), based on current estimates of future performance factors and forfeiture rates.Diluted shares outstanding:

Calculated as the change in production determined on a per weighted average shares outstanding basis over a predefined period of time, expressed as a compounded, annualized return percentage. Measuring production growth per share better reflects the interests of our existing shareholders by reflecting the dilutive impact of equity issuances.Production per share growth:

used as a measure of capital efficiency, calculated by dividing the applicable capital expenditures for the period, including the change in undiscounted FDC (future development capital), by the change in the reserves, incorporating revisions and production, for the same period.F&D (finding and development) and FD&A (finding, development and acquisition) costs:

A non-GAAP ratio that is calculated by dividing the Operating Netback, excluding PRRT and realized hedging gains and losses, by the cost of adding reserves (F&D and FD&A cost). Management assesses operating recycle ratio as a measure of the reinvestment of earnings.Operating Recycle Ratio:

Natural gas volumes have been converted on the basis of six thousand cubic feet of natural gas to one barrel of oil equivalent. Barrels of oil equivalent (boe) may be misleading, particularly if used in isolation. A boe conversion ratio of six thousand cubic feet to one barrel of oil is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.

This document discloses certain oil and gas metrics, including reserve life index, finding, development and acquisition ("FD&A") costs, future development capital ("FDC") costs, 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 in this document to provide readers with additional measures to evaluate the Company's performance; however, such measures are not reliable indicators of the Company's future performance and future performance may not compare to the Company's performance in previous periods and therefore such metrics should not be unduly relied upon.

Estimates of Drilling Locations: Unbooked drilling locations are the internal estimates of Vermilion based on Vermilion's prospective acreage and an assumption 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 (including contingent and prospective). Unbooked locations have been identified by Vermilion's management as an estimation of Vermilion's multi-year drilling activities based on evaluation of applicable geologic, seismic, engineering, production and reserves information. There is no certainty that Vermilion will drill all unbooked drilling locations and if drilled there is no certainty that such locations will result in additional oil and natural gas reserves, resources or production. The drilling locations on which Vermilion will actually drill wells, including the number and timing thereof is ultimately dependent upon the availability of funding, regulatory approvals, seasonal restrictions, oil and natural gas prices, costs, actual drilling results, additional reservoir information that is obtained and other factors. While a certain number of the unbooked drilling locations have been de-risked by Vermilion drilling existing wells in relative close proximity to such unbooked drilling locations, the majority of other unbooked drilling locations are farther away from existing wells where management of Vermilion 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.

Year-end total proved plus probable ("2P") reserves increased by 36% year over year to 592 mmboe⁽¹³⁾
Proved developed producing ("PDP") and 2P finding, development and acquisition ("FD&A") costs⁽¹⁴⁾⁽¹⁵⁾
Before-tax net present value ("NPV") of 2P reserves, discounted at 10%, of $4.8 billion⁽¹³⁾⁽¹³⁾

Generated $241 million ($1.57/basic share)⁽²⁾⁽¹⁾⁽⁶⁾⁽³⁾
Vermilion reduced net debt by $42 million and returned $26 million to shareholders through dividends and share buybacks, comprising $20 million in dividends and the repurchase and cancellation of 0.6 million shares through the NCIB.
Realized an average natural gas price of $5.50/mcf after hedging in Q4 2025, more than twice the AECO benchmark, reflecting diversified market access.
Reported a net loss from continuing operations of $438 million ($2.86/basic share), driven by non-cash impairments on legacy assets with no impact on quarterly FFO or FCF.
Production averaged 121,308 boe/d⁽¹⁰⁾⁽¹⁰⁾⁽¹⁰⁾
During the quarter, Vermilion brought online several top performing Deep Basin wells, including wells that were deferred to mid-Q4 2025 to maximize profitability. With these wells coming on production in the quarter, as well as previously shut-in wells being brought back online, production from continuing operations in Canada was over 5,000 boe/d higher than the prior quarter.
In the Montney, our Mica asset generated record production of over 16,000 boe/d in Q4 2025, while we spud the most recent pad and remained focused on continued improvement of both operating and drilling and completion costs.
In the Netherlands, successfully brought two (1.2 net) conventional natural gas wells on production and advanced permitting and preparatory work for additional drilling in 2026.
In Germany, advanced infrastructure construction for the Wisselshorst well, which remains on track for first production in mid-2026, while the Osterheide well delivered average production of approximately 10 mmcf/d, representing a 45% increase from Q3 2025.
Operationally, the fourth quarter of 2025 was reflective of our focus on continuous improvement. Unit operating costs in Canada benefitted from greater operational scale, high-quality assets and commitment to cost management to reach their lowest level in over a decade, which drove corporate unit operating costs of $11.86/boe, the lowest since 2020.

Vermilion expects Q1 2026 production to average 122,000 to 124,000 boe/d (70% natural gas)⁽¹⁶⁾⁽¹⁶⁾
Declared a quarterly cash dividend of $0.135 per common share, payable on March 31, 2026, to shareholders of record on March 13, 2026. As previously announced, this quarterly cash dividend represents a 4% increase over the prior dividend, and the fifth consecutive year of dividend increases.
