This document discloses certain oil and gas metrics, including DCET 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 MD&A 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. DCET costs includes all capital spent to drill, complete, equip and tie-in a well. Additional oil and gas metrics in this document may include, but are not limited to:

Boe Equivalency: Per barrel of oil equivalent amounts have been calculated using a conversion rate of six thousand cubic feet of natural gas to one barrel of oil equivalent (6:1). Barrel of oil equivalents (boe) may be misleading, particularly if used in isolation. A boe conversion ratio of 6 Mcf:1 bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. In addition, as the value ratio between natural gas and crude oil based on the current prices of natural gas and crude oil is significantly different from the energy equivalency of 6:1, utilizing a conversion on a 6:1 basis may be misleading as an indication of value.

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.

Highlights

Q3 2025 Results

Generated $254 million ($1.65/basic share)^(2)^<br>of fund flows from operations ("FFO")^(1)^. Exploration and development (“E&D”) capital expenditures^(3)^<br>were $146 million, resulting in free cash flow ("FCF")^(5)^ of $108 million.
Reduced net debt^(6)^ by over<br>$650 million since Q1 2025, bringing net debt to $1.38 billion as at September 30, 2025. This resulted in a net debt to four quarter trailing<br>FFO^(7)^ ratio of 1.4 times, reflecting continued progress toward strengthening Vermilion's balance sheet.
--- ---
Vermilion reported comprehensive income<br>of $35 million ($0.23/basic share).
--- ---
Driven by the successful asset repositioning,<br>including realized Deep Basin synergies in the second half of 2025, Vermilion reduced the upper end of annual E&D capital expenditure<br>guidance by $20 million, from $660 million to $640 million, and reduced annual operating cost guidance by over $10 million.
--- ---
Vermilion realized an average natural gas<br>price of $4.36/mcf before hedging and $5.62/mcf after hedging in Q3 2025 - approximately seven and nine times the AECO 5A benchmark, respectively.<br>To optimize margins, the Company elected to shut in a portion of our gas production and deferred the start-up of several wells, which<br>resulted in approximately 3,000 boe/d of production impact in the quarter, with production expected to resume in Q4 2025 amid stronger<br>pricing.
--- ---
Vermilion returned $26 million to shareholders<br>through dividends and share buybacks, comprising $20 million in dividends and $6 million of share buybacks. During the quarter, the Company<br>repurchased and cancelled 0.6 million shares through the NCIB for a total of 2.5 million shares repurchased year-to-date.
--- ---
Production averaged 119,062 boe/d^(9)^(67% natural gas and 33% crude oil and liquids), comprising 88,763 boe/d^(9)^ from the North American assets and 30,299<br>boe/d^(9)^ from the International assets.
--- ---
Drilled 13 (12.4 net) wells in the Deep<br>Basin, demonstrating strong results across our significant land base. Our Q3 2025 drilling program delivered well in excess of our expectations,<br>demonstrating the quality of our land base and reinforcing our confidence in the development potential of these assets.
--- ---
Executed a successful two-well (1.2 net)<br>drilling program in the Netherlands in Q3 2025, discovering commercial gas in both the Rotliegend and Zechstein formations, with both<br>wells expected to be completed, tied in and brought on production in Q4 2025. These wells build on our two-decade track record of exploration<br>success in the Netherlands, and, combined with recent discoveries in Germany, underscore Vermilion’s broader European gas exploration<br>expertise.

2026 Budget

Vermilion's Board of Directors has approved<br>an E&D capital budget of $600 to $630 million for 2026. This capital budget prioritizes our global gas assets, with approximately<br>85% of capital invested in this part of Vermilion’s portfolio. The Company expects to deliver annual average production of 118,000<br>to 122,000 boe/d (70% natural gas)^(12)^, focusing on financial discipline and free cash flow generation. The 2026 budget reflects<br>the Company's lower overall cost structure of the enhanced portfolio, with 30% improvements in capital efficiencies and unit operating<br>costs driven by increased operational scale in our core areas.
Vermilion plans to invest approximately<br>$415 million of E&D capital into liquids-rich gas assets in the Montney and Deep Basin in 2026, including drilling a total of 49 (44.8<br>net) wells and investing in key infrastructure. Vermilion will run a three-rig drilling program in the Deep Basin, drilling 43 (38.8 net)<br>wells with minimal infrastructure requirements. In the Montney, we plan to drill six (6.0 net) wells, while completing and bringing on<br>production ten (10.0 net) wells and investing to expand existing infrastructure.
--- ---
Vermilion plans to invest approximately<br>$200 million across its International assets in 2026, with a continued emphasis on European natural gas exploration and development. In<br>Germany, the Company plans to build out key infrastructure and prepare for two (1.3 net) follow-up wells at the Wisselshorst discovery<br>in early 2027, while bringing on production from the first Wisselshorst discovery in mid-2026. We plan to drill one (0.5 net) well in<br>the Netherlands, while continuing to fund economic workover and optimization projects throughout the International portfolio.
--- ---
Plan to increase the quarterly cash dividend<br>by 4% to $0.135 CAD per share, effective with the Q1 2026 dividend payable on March 31, 2026, subject to approval by the Company's Board<br>of Directors in March 2026.
--- ---
Outlook
---

Vermilion expects Q4 2025 production to<br>average 119,000 to 121,000 boe/d (69% natural gas)^(12)^, with full-year production of approximately 119,500 boe/d (65% natural<br>gas)^(12)^ on E&D capital expenditures of $630 to $640 million.
Declared a quarterly cash dividend of $0.13<br>per common share, payable on December 31, 2025, to shareholders of record on December 15, 2025.

The measure is used by management to assess the contribution<br>of each business unit to Vermilion’s ability to generate income necessary to pay dividends, repay debt, fund asset retirement obligations,<br>and make capital investments. FFO does not have a standardized meaning under IFRS® Accounting Standards and therefore may not be comparable<br>to similar measures provided by other issuers. More information and a reconciliation to net earnings (loss), the most directly comparable<br>primary financial statement measure, can be found in the “Non-GAAP and Other Specified Financial Measures” section of this<br>document. Fund flows from continuing operations and fund flows from discontinued operations are calculated in the same manner as FFO and<br>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<br>operations (total of segments and non-GAAP financial measure) by the basic weighted average shares outstanding as defined under IFRS Accounting<br>Standards. Fund flows from operations per diluted share is calculated by dividing fund flows from operations by the sum of basic weighted<br>average shares outstanding and incremental shares issuable under the equity-based compensation plans as determined using the treasury<br>stock method. Management assesses fund flows from operations on a per share basis as we believe this provides a measure of our operating<br>performance after taking into account the issuance and potential future issuance of Vermilion common shares. More information and a reconciliation<br>to cash flows used in investing activities, the most directly comparable primary financial statement measure, can be found in the “Non-GAAP<br>and Other Specified Financial Measures” section of this document. Fund flows from continuing operations per basic and diluted share<br>and fund flows from discontinued operations per basic and diluted share are calculated in the same manner as FFO per basic and diluted<br>share.

^^

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

^^

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

^^

^(5)^ Free cash flow (FCF) and excess free cash flow (EFCF) are non-GAAP financial measures most directly comparable<br>to cash flows from operating activities. FCF is calculated as FFO less drilling and development costs and exploration and evaluation costs<br>and EFCF is calculated as FCF less payments on lease obligations and asset retirement obligations settled. FCF is used by management to<br>determine the funding available for investing and financing activities including payment of dividends, repayment of long-term debt, reallocation<br>into existing business units and deployment into new ventures. EFCF is used by management to determine the funding available to return<br>to shareholders after costs attributable to normal business operations. FCF and EFCF do not have standardized meanings under IFRS Accounting<br>Standards and therefore may not be comparable to similar measures provided by other issuers. More information and a reconciliation to<br>cash flows from operating activities, the most directly comparable primary financial statement measure, can be found in the “Non-GAAP<br>and Other Specified Financial Measures” section of this document.
^(6)^ Net debt is a capital management measure in accordance with IAS 1 “Presentation of Financial Statements”<br>that is most directly comparable to long-term debt and is calculated as long-term debt (excluding unrealized foreign exchange on swapped<br>USD borrowings) plus adjusted working deficit (capital), a non-GAAP financial measure described in the “Non-GAAP and Other Specified<br>Financial Measures” section of this document. Management considers this a helpful representation of Vermilion’s net financing<br>obligations after adjusting for the timing of working capital fluctuations. More information and a reconciliation to long-term debt, the<br>most directly comparable primary financial statement measure, can be found in the “Non-GAAP and Other Specified Financial Measures”<br>section of this document.
--- ---

^^

^(7)^ Net debt to four quarter trailing fund flows from operations is a non-GAAP ratio and is not a standardized<br>financial measure under IFRS Accounting Standards and therefore may not be comparable to similar measures disclosed by other issuers.<br>Net debt to four quarter FFO is calculated as net debt divided by FFO from the preceding four quarters. Management uses this measure to<br>assess the Company’s ability to repay debt. More information can be found in the “Non-GAAP and Other Specified Financial Measures”<br>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.

^^

^(8)^ Diluted shares outstanding represents the sum of shares outstanding at the period end plus outstanding<br>awards under the Long-term Incentive Plan, based on current estimates of future performance factors and forfeiture rates.

^^

^(9)^ Please refer to Supplemental Table 4 “Production” of the accompanying Management’s Discussion<br>and Analysis for disclosure by product type.

^^

^(10)^ Operating netback is a non-GAAP financial measure that is not standardized under IFRS Accounting Standards<br>and may not be comparable to similar measures disclosed by other issuers. Operating netback is most directly comparable to net (loss)<br>earnings and is calculated as sales less royalties, operating expense, transportation expense, PRRT expense, and realized hedging (gain)<br>loss, and when presented on a per unit basis is a non-GAAP ratio. Management assesses operating netback as a measure of the profitability<br>and efficiency of our field operations. More information and a reconciliation to net (loss) earnings, the most directly comparable primary<br>financial statement measure, can be found in the “Non-GAAP and Other Specified Financial Measures” section of this document.

^^

^(11)^ Fund flows from operations per boe is a non-GAAP ratio that is not standardized under IFRS Accounting<br>Standards and may not be comparable to similar measures disclosed by other issuers. FFO per boe is calculated as FFO divided by boe production.<br>FFO per boe is used by management to assess the profitability of Vermilion’s business units and Vermilion as a whole. More information<br>can be found in the “Non-GAAP and Other Specified Financial Measures” section of this document. Fund flows from continuing<br>operations per boe and fund flows from discontinued operations per boe are calculated in the same manner as FFO per boe.

^^

^(12)^ Based on Company estimates as at October 27, 2025.

Vermilion delivered a strong third quarter, both operationally and financially, with production at the upper end of our guidance range and robust fund flows from operations. Our continued focus on asset repositioning has led to repeatable improvements in capital and operating efficiencies, supported by longer-duration assets. As a result, we have reduced the upper end of our 2025 capital guidance by $20 million and lowered full-year operating cost guidance by over $10 million. These improvements are structural in nature and have been embedded into our 2026 budget guidance, which is inclusive of realized Deep Basin synergies. Compared to 2024 - the most recent year prior to our asset high-grading - our 2026 operational guidance reflects an over 40% increase in production per share, as well as a 30% structural improvement in capital efficiency and operating costs. Following our repositioning, 85% of our production and capital is now concentrated in larger, core areas of our global gas portfolio. We believe this better positions Vermilion for long-term success.

Our ability to deliver strong Q3 2025 results despite pricing volatility underscores the strength of our differentiated portfolio. Vermilion’s assets drove strong operational and financial results despite downward pressure on AECO pricing in response to imbalanced supply-demand dynamics. Vermilion's realized gas price, excluding realized hedging gain, was $4.36/mcf, and including realized hedging gain was $5.62/mcf, approximately seven and nine times the daily benchmark, respectively. This outperformance was driven by our exposure to premium-priced European gas, supplemented by a robust hedging program, and highlights the benefit of being a global gas producer. To optimize margins, the Company elected to shut in a portion of our gas production and deferred the start-up of several wells, which resulted in approximately 3,000 boe/d of production impact in the quarter. The Company expects to bring the shut-in production and new wells online in Q4 2025 into a more supportive pricing environment.

We ramped up to a three-rig drilling program in the Deep Basin during Q3 2025, targeting several discrete zones and delivering strong results across our extensive 1.1 million net acre position. This level of activity reflects a full-scale drilling program and results to-date have exceeded expectations, highlighting the quality of our land base and reinforcing confidence in the asset’s long-term potential. Looking ahead, we plan to maintain a steady three-rig program to efficiently advance development across the Deep Basin.

Vermilion executed a successful two-well (1.2 net) drilling program in the Netherlands in Q3 2025, discovering commercial gas in both the Rotliegend and Zechstein formations, with both wells expected to be completed, tied in and brought on production in Q4 2025. These wells build on our two-decade track record of exploration success in the Netherlands, and, combined with recent discoveries in Germany, underscore Vermilion’s broader European gas exploration expertise. The first well of the 2024 Germany exploration program, Osterheide, continues to produce at a restricted rate of 1,100 boe/d, while the second well, Wisselshorst, is on track for start-up by mid-2026, with preparations underway for follow-up drilling.

The fourth quarter of 2025 will represent the first full quarter of Vermilion's repositioned global gas portfolio following a busy period of acquisition and disposition activity. With demonstrated successes in exploration and development across our asset base and an improving backdrop for natural gas pricing in Canada, we believe Vermilion is uniquely positioned to benefit from global gas demand.

Q3 2025 Review

Vermilion generated $254 million of fund flows from operations ("FFO") in Q3 2025, with free cash flow ("FCF") of $108 million reflecting E&D capital expenditures of $146 million. Production averaged 119,062 boe/d (67% gas)^(1)^, which was at the upper end of our Q3 2025 guidance range. Production from Vermilion's North American operations averaged 88,763 boe/d^(1)^, inclusive of the divestments of the Company's assets in Saskatchewan and the United States, which closed in July 2025, as well as shut-in gas and the impact of planned turnaround activity. Production from Vermilion's International operations averaged 30,299 boe/d^(1)^ in Q3 2025, an increase of 2% from the previous quarter due to strong performance across the International business units.

In Canada, capital activity ramped up in Q3 2025, with the Company executing a three-rig drilling program in the Deep Basin. Vermilion drilled thirteen (12.4 net), completed twelve (11.3 net), and brought on production three (2.4 net) liquids-rich gas wells in the Deep Basin and brought on production one (1.0 net) liquids-rich gas well in the Montney. The Company elected to defer start-up of several wells drilled and completed in Q3 2025 to Q4 2025, with production expected to come online amid stronger pricing.

In the Netherlands, Vermilion drilled two (1.2 net) conventional natural gas wells. Both wells discovered commercial hydrocarbons and are planned to be completed, tied in and brought on production in Q4 2025. In Germany, the Osterheide well (1.0 net) that was brought on production at the end of Q1 2025 continued to produce at approximately 1,100 boe/d in Q3 2025.

2026 Budget and Guidance

Vermilion's Board of Directors has approved an E&D capital budget of $600 to $630 million for 2026, with approximately 85% allocated to our global gas portfolio. Key investments include drilling and strategic infrastructure investment on the Montney asset, high-return liquids-rich gas wells in the Deep Basin, and drilling and infrastructure capital investment in Germany and the Netherlands. The Company expects to deliver annual average production of 118,000 to 122,000 boe/d (70% natural gas)^(2)^, focusing on financial discipline and free cash flow generation. The 2026 budget reflects the lower overall cost structure of the Company's enhanced portfolio, with 30% improvements in capital efficiencies and unit operating costs driven by increased operational scale in our core operating areas.

Canada

Vermilion plans to invest approximately $415 million of E&D capital into liquids-rich gas assets in the Montney and Deep Basin in 2026, including drilling a total of 49 (44.8 net) wells and investing in key infrastructure. Vermilion will run a three-rig drilling program in the Deep Basin, drilling 43 (38.8 net) wells with minimal infrastructure requirements. In the Montney, we plan to drill six (6.0 net) wells, and complete and bring on production ten (10.0 net) wells, while investing to expand existing infrastructure. Third-party infrastructure is expected to increase total Montney throughput capacity to 28,000 boe/d within the next few years, after which the ongoing capital commitment will decrease to approximately eight wells per year to maintain production, with no further infrastructure expansion anticipated.

International

Vermilion plans to invest approximately $200 million across its International assets in 2026, with a continued emphasis on European natural gas exploration and development. In Germany, the Company plans to build out key infrastructure and prepare for two (1.3 net) follow-up wells at the Wisselshorst discovery in early 2027, while bringing on production from the first Wisselshorst discovery in mid-2026. We plan to drill one (0.5 net) well in the Netherlands, while continuing to fund economic workover and optimization projects throughout the international portfolio. We expect maintenance spending will be higher than previous years due to non-recurring turnarounds across our international asset base, including a planned 32-day turnaround in Ireland that has a scope of work that occurs every five years.

Financial Outlook and Return of Capital

The Company’s shareholder returns priorities remain unchanged, as we will focus on funding the base dividend, buying back shares when warranted, and directing excess free cash flow to debt reduction. Vermilion is pleased to announce a planned 4% increase to the quarterly cash dividend to $0.135 CAD per share, effective with the Q1 2026 dividend payable on March 31, 2026, subject to approval by the Company's Board of Directors in March 2026.

The $20 million reduction in the upper range of E&D capital expenditures guidance reflects the improved efficiency of our capital program.

Commodity Hedging

Vermilion hedges to manage commodity price exposures and increase the stability of our cash flows. In aggregate, we have 55% of our expected net-of-royalty production hedged for the remainder of 2025. With respect to individual commodity products, we have hedged 54% of our European natural gas production, 59% of our crude oil production, and 49% 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

Fund flows from operations (FFO): Most directly comparable to net earnings (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.

Non-GAAP Financial Measures andNon-GAAP Ratios

^^

Fund flows from operations per basicand diluted share: 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 boe:**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.

^^

Free cash flow (FCF) and excessfree cash flow (EFCF): 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.

Capital expenditures: 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.

($M) Q3 2025 Q3 202 4 2025 2024

Capital expenditures 145,562 121,269 443,170 422,321

**Payout and payout % of FFO:**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.

% of fund flows from operations 70 % 56 % 69 % 54 %

Return on capital employed (ROCE): A non-GAAP ratio**,** 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 earnings (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.

Twelve Months Ended
($M) Sep 30, 2025 Sep 30, 2024
Net loss (234,264) (831,559)

EBIT (138,119) (752,606)
Average capital employed 5,513,299 5,995,108
Return on capital employed (3) % (13) %

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

Acquisitions: 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.

($M) Q3 2025 Q3 2024 2025 2024
Acquisitions, net of cash acquired 1,068 1,642 1,087,115 7,471

Acquisition of securities 9,373
Acquired working capital deficit 23,179
Acquisitions 1,068 1,642 1,123,657 16,844

Operating netback: 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 earnings (loss). Management assesses operating netback as a measure of the profitability and efficiency of our field operations.


Net debt to four quarter trailing fundflows from operations: 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.

Capital Management Measure

Net debt: 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 and current lease liabilities), and represents Vermilion's net financing obligations after adjusting for the timing of working capital fluctuations.

Supplementary Financial Measures

**Diluted shares outstanding:**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.

('000s of shares) Q3 2025 Q3 2024
Shares outstanding 153,434 155,348
Potential shares issuable pursuant to the LTIP 4,717 3,564
Diluted shares outstanding 158,151 158,912

Production per share growth: 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.

F&D (finding and development) andFD&A (finding, development and acquisition) costs: 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.

Operating Recycle Ratio: A non-GAAP ratio that is calculated by dividing the Operating Netback, excluding realized gain (loss) on derivatives and petroleum resource rent tax, 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.

Management's Discussion and Analysis

The following is Management’s Discussion and Analysis (“MD&A”), dated November 5, 2025, of Vermilion Energy Inc.’s (“Vermilion”, “we”, “our”, “us” or the “Company”) operating and financial results as at and for the three and nine months ended September 30, 2025 compared with the corresponding period in the prior year.

This discussion should be read in conjunction with the unaudited condensed consolidated interim financial statements for the three and nine months ended September 30, 2025, and the audited consolidated financial statements for the years ended December 31, 2024 and 2023, together with the accompanying notes. Additional information relating to Vermilion, including its Annual Information Form, is available on SEDAR+ at www.sedarplus.ca or on Vermilion’s website at www.vermilionenergy.com.

The unaudited condensed consolidated interim financial statements for the three and nine months ended September 30, 2025, and comparative information have been prepared in Canadian dollars, except where another currency has been indicated, and in accordance with IAS 34, "Interim Financial Reporting", as issued by the International Accounting Standards Board ("IASB").

The operating results attributable to the Company's Saskatchewan and United States operations have been classified and presented as discontinued operations, with all other operating results presented as continuing operations. The prior period results have been presented to conform with current period presentation. See Note 4 - "Discontinued Operations" of the condensed consolidated interim financial statements for the three and nine months ended September 30, 2025, for additional information.

This MD&A includes references to certain financial measures which are not specified, defined, or determined under IFRS® Accounting Standards as issued by the IASB ("IFRS Accounting Standards") and are therefore considered non-GAAP and other specified financial measures. These financial measures are unlikely to be comparable to similar financial measures presented by other issuers. For a full description of these non-GAAP and other specified financial measures and a reconciliation of these measures to their most directly comparable GAAP measures, please refer to “Non-GAAP and Other Specified Financial Measures”.

Product Type Disclosure

Under National Instrument 51-101 "Standards of Disclosure for Oil and Gas Activities", disclosure of production volumes should include segmentation by product type as defined in the instrument. In this report, references to "crude oil" and "light and medium crude oil" mean "light crude oil and medium crude oil" and references to "natural gas" mean "conventional natural gas" and "shale gas".

In addition, in Supplemental Table 4 "Production", Vermilion provides a reconciliation from total production volumes to product type and also a reconciliation of "crude oil and condensate" and "NGLs" to the product types "light crude oil and medium crude oil" and "natural gas liquids".

Production volumes reported are based on quantities as measured at the first point of sale.

^(2)^ Fund flows from operations (FFO) and FFO per share are a total of segments measure and supplementary financial<br>measure most directly comparable to net earnings (loss) and net earnings (loss) per share, respectively. The measures do not have a standardized<br>meaning under IFRS Accounting Standards and therefore may not be comparable to similar measures presented by other issuers. FFO is comprised<br>of sales less royalties, transportation, operating, general and administrative (G&A), corporate income tax, PRRT, interest expense,<br>equity based compensation settled in cash, realized gain (loss) on derivatives, plus realized gain (loss) on foreign exchange and realized<br>other income (expense). The measure is used to assess the contribution of each business unit to Vermilion's ability to generate income<br>necessary to pay dividends, repay debt, fund asset retirement obligations and make capital investments. A reconciliation to the primary<br>financial statement measures can be found within the "Non-GAAP and Other Specified Financial Measures" section of this MD&A.<br>Fund flows from continuing operations and fund flows from discontinued operations are calculated in the same manner as FFO and are most<br>directly comparable to net earnings (loss) from continuing operations and net earnings (loss) discontinued operations, respectively.
--- ---
^(3)^ Free cash flow (FCF) is a non-GAAP financial measure most directly comparable to cash flows from operating<br>activities; it does not have a standardized meaning under IFRS Accounting Standards and therefore may not be comparable to similar measures<br>presented by other issuers. FCF is comprised of fund flows from operations less drilling and development costs and exploration and evaluation<br>costs. FCF is used to determine the funding available for investing and financing activities including payment of dividends, repayment<br>of long-term debt, reallocation into existing business units and deployment into new ventures. A reconciliation to primary financial statement<br>measures can be found within the "Non-GAAP and Other Specified Financial Measures" section of this MD&A.
--- ---
^(4)^ Net debt is a capital management measure in accordance with IAS 1 "Presentation of Financial Statements"<br>and is most directly comparable to long-term debt. Net debt is comprised of long-term debt (excluding unrealized foreign exchange on swapped<br>USD borrowings) plus adjusted working capital (defined as current assets less current liabilities, excluding current derivatives and current<br>lease liabilities), and represents Vermilion's net financing obligations after adjusting for the timing of working capital fluctuations.<br>Net debt excludes lease obligations which are secured by a corresponding right-of-use asset. A reconciliation to the primary financial<br>statement measures can be found within the "Financial Position Review" section of this MD&A.
--- ---
^(5)^ Capital expenditures is a non-GAAP financial measure that does not have a standardized meaning under IFRS<br>Accounting Standards and therefore may not be comparable to similar measures presented by other issuers. The measure is calculated as<br>the sum of drilling and development costs and exploration and evaluation costs from the Consolidated Statements of Cash Flows. We consider<br>capital expenditures to be a useful measure of our investment in our existing asset base. Capital expenditures are also referred to as<br>E&D capital. A reconciliation to the primary financial statement measures can be found within the "Non-GAAP and Other Specified<br>Financial Measures" section of this MD&A.
--- ---
^(6)^ Acquisitions is a non-GAAP financial measure that does not have a standardized meaning under IFRS Accounting<br>Standards and therefore may not be comparable to similar measures presented by other issuers. The measure is calculated as the sum of<br>acquisitions, net of cash and acquisitions of securities from the Consolidated Statements of Cash Flows, Vermilion common shares issued<br>as consideration, the estimated value of contingent consideration, the amount of acquiree's outstanding long-term debt assumed, and net<br>acquired working capital deficit or surplus. We believe that including these components provides a useful measure of the economic investment<br>associated with our acquisition activity. A reconciliation to the acquisitions line item in the Consolidated Statements of Cash Flows<br>can be found in "Supplemental Table 3: Capital Expenditures and Acquisitions" section of this MD&A.

Financial performance review

Q3 2025 vs. Q3 2024

We recorded a net earnings of $2.6 million<br>($0.02/basic share) for Q3 2025 compared to $51.7 million ($0.33/basic share) in Q3 2024. The change in net earnings was primarily due<br>to higher deferred taxes, the foreign exchange impact on our US denominated senior notes and Euro denominated intercompany loans, depletion<br>and depreciation on higher production, and a net loss recognized on discontinued operations. The decrease was partially offset by higher<br>fund flows from operations on the newly acquired production from the Westbrick assets and favourable changes in our mark-to-market derivative<br>position.

| Vermilion Energy Inc.  ■  Page 18  ■  2025 Third Quarter Report |

| --- | | • | Cash flows from operating activities were<br>$389.5 million in Q3 2025 compared to $134.5 million in Q3 2024, while fund flows from operations decreased to $253.8 million in Q3 2025<br>from $275.0 million in Q3 2024. The decrease in FFO was primarily driven by lower pricing and higher interest expenses due to a higher<br>long-term debt balance, partially offset by stronger operational performance from the Westbrick assets acquired and new wells coming on<br>production offsetting dispositions. Variances between cash flows from operating activities and fund flows from operations are primarily<br>driven by working capital timing differences, including lower tax liabilities at the end of Q3 2025. | | --- | --- |

Q3 2025 YTD vs. Q3 2024 YTD

For the nine months ended September 30,<br>2025, we recorded a net loss of $215.9 million compared to $28.4 million for the comparable period in 2024. The increase in net loss was<br>primarily attributable to impairment taken on disposed assets and lower fund flows from operations driven by lower realized gains on derivative<br>contracts. The increase was partially offset by favourable changes in our mark-to-market derivative position, primarily on our European<br>natural gas contracts and the foreign exchange impact on our US denominated senior notes and Euro denominated intercompany loan. The foreign<br>exchange loss on our Euro denominated intercompany loan is offset against the favourable currency translation adjustments recognized within<br>other comprehensive income (loss).

For the nine months ended September 30,<br>2025 as compared to the same period in 2024, cash flows from operating activities increased by $55.1 million to $810.3 million and FFO<br>decreased by $173.6 million to $769.5 million. The decrease in FFO was primarily driven by a reduction in realized gains on derivative<br>contracts of $195.9 million and higher interest expense on Q1 refinancing activities. This was partially offset by stronger operational<br>performance driven by the Westbrick acquisition, and improved commodity pricing. Variances between cash flows from operating activities<br>and fund flows from operations are primarily driven by working capital timing differences.
Production review

Q3 2025 vs. Q3 2024

Consolidated average production increased<br>41% to 119,062 boe/d in Q3 2025 compared to Q3 2024 production of 84,173 boe/d. Production increased as a result of the Westbrick acquisition<br>which closed at the end of February 2025, combined with increased production in Australia, Germany and Central and Eastern Europe. The<br>increases were partially offset by the United States and Saskatchewan dispositions and natural well decline in Ireland.

2025 vs. 2024

Consolidated average production increased<br>to 119,451 boe/d in the nine months ended September 30, 2025 compared to the prior year comparative period production of 84,881 boe/d.<br>Production increased primarily as a result of the Westbrick acquisition, partially offset by the United States and Saskatchewan dispositions.
Activity review
---

For the three months ended September 30, 2025, capital expenditures were $145.6 million.

In our North America core region, we invested<br>capital expenditures of $90.4 million, primarily within our liquids-rich gas assets in Canada:
In the Deep Basin, we drilled thirteen<br>(12.4 net), completed twelve (11.3 net), and brought on production three (2.4 net) liquids-rich conventional natural gas wells. The Company<br>elected to defer start-up of several drilled and completed wells to Q4 2025 in response to weak commodity pricing in Q3 2025.
--- ---
In the Montney, we brought on production<br>one (1.0 net) liquids-rich shale gas well and invested in facilities and maintenance on our Mica asset.

Free cash flow

Free cash flow decreased by $194.4 million<br>to $326.3 million for the nine months ended September 30, 2025 compared to the prior year period primarily due to lower fund<br>flows from operations driven by lower realized gains on derivative contracts and lower fund flows from discontinued operations, partially<br>offset by stronger operational performance from the Westbrick assets acquired.

Long-term debt and net debt

As at September 30, 2025, long-term debt<br>increased to $1.3 billion (December 31, 2024 - $1.0 billion) primarily due to financing activities related to the $1.1 billion<br>Westbrick acquisition. This increase was partially offset by proceeds received from the disposition of non-core assets in the United States<br>and Saskatchewan. During the nine months ended September 30, 2025, a $450.0 million term loan was drawn and subsequently repaid, we issued<br>$563.0 million (US $400.0 million) 2033 senior unsecured notes to finance the repayment of our $399.5 million (US $300.0 million)<br>2025 senior unsecured notes which matured in the first quarter, a net draw was made on our revolving credit facility of $196.9 million<br>and we repurchased $27.7 million of our 2030 senior unsecured notes. Long-term debt also decreased on the foreign exchange impact of the<br>US dollar weakening against the Canadian dollar on our US denominated senior unsecured notes.
As at September 30, 2025, net debt<br>totaled $1.4 billion, or an increase of $0.4 billion from December 31, 2024. The increase was primarily driven by the financing of<br>the Westbrick acquisition in Q1 2025, partially offset by proceeds from the disposition of our U.S. and Saskatchewan assets and strong<br>free cash flow generation.
--- ---
The ratio of net debt to four quarter trailing<br>fund flows from operations^(1)^ increased to 1.4 as at September 30, 2025 (December 31, 2024 - 0.8) primarily due to<br>higher net debt on the 2025 acquisition and disposition activity.
--- ---
^(1)^ Net debt to four quarter trailing fund flows from operations is a supplementary financial measure that<br>does not have a standardized meaning under IFRS Accounting Standards and therefore may not be comparable to similar measures presented<br>by other issuers. It is calculated as net debt (capital measure) over the FFO from the preceding four quarters (total of segments measure).<br>The measure is used to assess our ability to repay debt. Subsequent to February 26, 2025, net debt to four quarter trailing fund flows<br>from operations is calculated inclusive of Westbrick Energy's pre-acquisition four quarter trailing fund flows from operations, as if<br>the acquisition of Westbrick Energy occurred at the beginning of the four-quarter trailing period, and exclusive of the four quarter trailing<br>fund flows from discontinued operations to reflect the Company’s ability to repay debt on a pro forma basis.

As an internationally diversified producer, we are exposed to a range of commodity prices. In our North America core region, our crude oil is sold at benchmarks linked to WTI (including the Edmonton Sweet index, the Saskatchewan LSB index, and the Canadian C5+ index) and our natural gas is sold at benchmarks linked to the AECO index (in Canada) or the Henry Hub ("HH") index (in the United States). In our International core region, our crude oil is sold with reference to Dated Brent and our natural gas is sold with reference to NBP, TTF, or indices highly correlated to TTF.

Crude oil prices decreased in Q3 2025 relative<br>to Q3 2024 on heightened macroeconomic uncertainty from tariff announcements, risk to global GDP growth, and consensus views of global<br>stockpiles growing in Q4 2025 and 2026. Canadian dollar WTI and Dated Brent both decreased by 13% in Q3 2025 relative to Q3 2024.
In Canadian dollar terms, year-over-year,<br>the Edmonton Sweet differential tightened by $1.55/bbl to a discount of $3.03/bbl against WTI, and the Saskatchewan LSB differential tightened<br>by $1.91/bbl to a discount of $4.67/bbl against WTI. These differentials have tightened due to decreased supply as a result of additional<br>TMX flows off the Canadian West coast. In addition, seasonally low crude inventory in Western Canada and low levels of apportionment on<br>pipelines into the United States have contributed to stronger Canadian differentials.
--- ---
Approximately<br>36% of Vermilion’s Q3 2025 crude oil and condensate production was priced at the Dated Brent index, which averaged a premium to<br>WTI of US$4.14/bbl, while the remainder of our crude oil and condensate production was priced at the Saskatchewan LSB, Canadian C5+, Edmonton<br>Sweet, and WTI indices.

In Canadian dollar terms, year-over-year,<br>prices for European natural gas at NBP and TTF increased by 31% and 29% respectively on a day ahead basis. On a month ahead basis, both<br>NBP and TTF increased by 33% . Prices increased in response to higher demand coming from the global LNG market, termination of Russian<br>gas exports to Europe through Ukraine as of January 1, 2025, and below average storage levels due to a colder winter leading to high withdrawals.
Year-over-year natural gas prices in Canadian<br>dollar terms at NYMEX HH increased by 66% and AECO 7A increased by 19%. AECO prices increased in Q1 2025 due to strong winter storage<br>withdrawals. In contrast, NYMEX Henry Hub performed relatively better, supported by growing U.S. natural gas demand and expanding LNG<br>exports in early 2025.
--- ---
For Q3 2025, average<br>European natural gas prices represented a $14.77/mcf premium to AECO 5A. Approximately 22% of our natural gas production in Q3 2025 benefited<br>from this premium European pricing (Q3 2024 - 41%). The decrease in our realized natural gas price from the prior period is primarily<br>due to increased North American natural gas pricing exposure on Westbrick assets acquired in Q1 2025.

Production from Vermilion's North American operations averaged 88,763 boe/d in Q3 2025, representing a 17% decrease from Q2 2025. The decline was primarily due to the divestiture of assets in Saskatchewan and the United States, which closed in July 2025. Additional contributing factors included shut-in gas volumes, the deferral of new well start-ups and the impact of planned turnaround activity.

In Q3 2025, Vermilion drilled thirteen (12.4 net), completed twelve (11.3 net), and brought on production three (2.4 net) liquids-rich conventional natural gas wells in the Deep Basin and brought on production one (1.0 net) liquids-rich shale gas well in the Montney.

Sales in North America increased for the nine months ended September 30, 2025 compared to the prior year primarily due to increased production in Alberta from the Westbrick acquisition, and in British Columbia with fifteen Mica Montney wells brought online in 2024 and thirteen in the first nine months of 2025. The increase was partially offset by decreased production in Saskatchewan and the United States due to disposition activity. Sales in North America decreased for the three months ended September 30, 2025 compared to the prior year primarily due to the Saskatchewan and United States dispositions that closed early in the quarter, partially offset by increased production in Alberta from the Westbrick acquisition. Sales decreased on a per boe basis for the three and nine months ended September 30, 2025 compared to the prior year periods primarily due to change in product mix on the acquisition and disposition activity.

Royalties in North America decreased on a dollar basis for the three and nine months ended September 30, 2025 compared to the same periods in the prior year primarily due to decreased crude production in Saskatchewan and the United States following the dispositions that closed early in the quarter and lower realized liquids pricing. The decrease was partially offset by royalties on production from the Westbrick acquisition in Q1 2025. Royalties decreased on a per unit basis for the three and nine months ended September 30, 2025 primarily due to lower realized crude prices and the higher gas weighting in our production mix following the Westbrick acquisition, subject to lower royalty rates relative to liquids.

Transportation expense in North America increased on a dollar basis for the three and nine months ended September 30, 2025 compared to the prior year comparable periods primarily due to transportation costs on acquired Westbrick assets in Q1 2025, partially offset by decreased transportation costs in Saskatchewan and the United States on disposal in early Q3 2025. On a per boe basis, transportation expense decreased for the three months ended September 30, 2025, primarily due to lower per unit costs on acquired production and increased for the nine months ended September 30, 2025, impacted by higher pipeline fees in British Columbia.

Operating expenses in North America increased for the three and nine months ended September 30, 2025, mainly due to the Westbrick acquisition in the first quarter of 2025, partially offset by lower expenses in Saskatchewan and the U.S. from the asset dispositions recently completed and reduced costs in British Columbia for downhole maintenance, trucking, and gas processing. Operating expense decreased on a per boe basis for the three and nine months ended September 30, 2025, primarily due to lower per unit operating costs on increased production impacted by the Westbrick acquisition and new wells coming on production in British Columbia.

Production from Vermilion's International operations averaged 30,299 boe/d in Q3 2025, an increase of 2% from the previous quarter due to strong performance across the International business units.

In the Netherlands, Vermilion drilled two (1.2 net) conventional natural gas wells. Both wells discovered commercial hydrocarbons and are planned to be completed, tied in and brought on production in Q4 2025. In Germany, the Osterheide well (1.0 net) that was brought on production at the end of Q1 2025 continued to produce at a restricted rate of approximately 1,100 boe/d in Q3 2025, driven by strong local demand.

Sales decreased on a dollar and per boe basis for the three months ended September 30, 2025 compared to the prior year primarily due to the lower realized liquids commodity prices. For the nine months ended September 30, 2025, sales decreased on a dollar basis compared to the prior year primarily due to the timing of inventory combined with lower realized crude oil pricing. Sales on a per boe basis for the nine months ended September 30, 2025 increased compared to the prior year primarily due to higher realized gas pricing partially offset by lower realized oil pricing.

Operating expenses increased on a dollar and per boe basis for the three months ended September 30, 2025 compared to same period in the prior year primarily due to higher sales volumes in Australia, higher fuel and electricity costs in France and a gas processing recovery recognized in the Netherlands in the prior year period. During the nine months ended September 30, 2025, operating expenses decreased on a dollar basis primarily due to lower sales volumes in Australia, combined with lower fuel and electricity fees in the Netherlands. On a per boe basis, operating expenses remained relatively flat for the nine months ended September 30, 2025 compared to the prior year.

Fluctuations in fund flows from operations, including fund flows from continuing operations and fund flows from discontinued operations may occur as a result of changes in production levels, commodity prices, and costs to produce petroleum and natural gas. In addition, fund flows from operations may be affected by the timing of crude oil shipments in Australia and France. When crude oil inventory is built up, the related operating expense, royalties, and depletion expense are deferred and carried as inventory on the consolidated balance sheet. When the crude oil inventory is subsequently drawn down, the related expenses are recognized within profit or loss.

| --- |

General and administration

For the three months ended September 30,<br>2025, general and administration expense increased compared to the same period in the prior year due to restructuring costs incurred in<br>Canada. General and administration expense increased for the nine months ended September 30, 2025 compared to the comparable period<br>in 2024 primarily due to transaction costs related to the Westbrick acquisition and restructuring costs in Canada.

Equity based compensation

Equity based compensation<br>included within funds flow from operations primarily relates to the settlement of withholding taxes on long-term incentives granted to<br>directors, officers, and employees under security-based arrangements via cash, which were previously settled through the issuance and<br>sale of shares from Treasury. Equity based compensation settled in cash decreased for the nine months ended September 30, 2025 compared<br>to the same periods in the prior year primarily due to the higher value of LTIP in the prior year.

PRRT and corporate income taxes

PRRT increased for the three months ended<br>September 30, 2025 and decreased for the nine months ended September 30, 2025 compared to the same periods in 2024 due to corresponding<br>changes in sales in Australia.
Corporate income taxes for the three and nine months ended September<br>30, 2025 decreased compared to the prior year comparable periods mainly due to lower revenues in the France and Netherlands business units<br>and accelerated tax depletion deductions related to recent capital programs in the Germany and Netherlands business units.
--- ---

Interest expense

Interest expense for the three and nine<br>months ended September 30, 2025 increased due to higher debt levels driven by the issuance of the 2033 senior notes for US $400.0<br>million, draws on the revolving credit facility and $450.0 million term loan, which was drawn in Q1 2025 and subsequently repaid. The<br>increases were partially offset by the repayment of the US $300.0 million 2025 senior notes.

Realized gain or loss on derivatives

For the three and nine months ended September 30,<br>2025, we recorded realized gains on our natural gas and crude oil hedges due to lower commodity pricing compared to the strike prices.
A listing of derivative positions as at<br>September 30, 2025 is included in “Supplemental Table 2” of this MD&A.
--- ---

Realized other income or expense

Realized other expense for the three months<br>ended September 30, 2025 remained relatively flat compared to the prior year. For the nine months ended September 30, 2025,<br>realized other expense increased primarily related to an estimated provision recognized to satisfy work commitments.
Net earnings (loss)
---

Fluctuations in net earnings (loss) from period-to-period are caused by changes in both cash and non-cash based income and charges. Cash based items are reflected in fund flows from operations. Non-cash items include: equity based compensation expense, unrealized gains and losses on derivative instruments, unrealized foreign exchange gains and losses, accretion, depletion and depreciation expense, and deferred taxes. In addition, non-cash items may also include gains or losses resulting from acquisition or disposition activity or charges resulting from impairment or impairment reversals.

Equity based compensation

Equity based compensation expense relates included within net earnings (loss) and excluded from funds flow from operations relates to non-cash compensation expense attributable to long-term incentives granted to directors, officers, and employees under security-based arrangements. Equity based compensation expense decreased for the three months ended September 30, 2025 versus the prior year primarily due to lower value of LTIP awards outstanding in the current year. Equity based compensation increased for the nine months ended September 30, 2025, primarily due to the cash settlement of previously share-based settled expenses at a higher value of LTIP in the prior year.

Unrealized gain or loss on derivative instruments

Unrealized gain or loss on derivative instruments arises as a result of changes in forecasts for future prices and rates. As Vermilion uses derivative instruments to manage the commodity price exposure of our future crude oil and natural gas production, we will normally recognize unrealized gains on derivative instruments when future commodity price forecasts decline and vice-versa. As derivative instruments are settled, the unrealized gain or loss previously recognized is reversed, and the settlement results in a realized gain or loss on derivative instruments.

| Vermilion Energy Inc.  ■  Page 30  ■  2025 Third Quarter Report |

| --- |

Cross currency interest rate swaps and foreign exchange swaps may be entered into to manage foreign exchange and interest rate exposures on USD denominated debt. Unrealized gains and losses on these instruments are partially offset by the unrealized foreign exchange losses and gains on the underlying debt.

For the three months ended September 30, 2025, we recognized a net unrealized gain on derivative instruments of $16.6 million. This consists of unrealized gains of $11.9 million on our cross currency interest rate swaps, $10.4 million on our crude oil and liquids commodity derivative instruments, and $3.5 million on our equity swaps, partially offset by unrealized losses of $6.1 million on our European natural gas commodity derivative instruments, $1.8 million on our North America gas commodity derivative instruments, and $1.3 million on our USD-to-CAD foreign exchange swaps.

For the nine months ended September 30, 2025, we recognized a net unrealized gain on derivative instruments of $62.4 million. This consists of unrealized gains of $86.4 million on our European natural gas commodity derivative instruments, $4.6 million on our crude oil and liquids commodity derivative instruments, and $4.8 million on our USD-to-CAD foreign exchange swaps, partially offset by unrealized losses of $10.0 million on our equity swaps, $6.2 million on our cross currency interest rate swaps, and $6.1 million on our North American gas commodity derivative instruments.

A net unrealized gain on derivative instruments of $11.0 million and $nil was recorded for the three and nine months ended September 30, 2025, respectively, relating to WTI swaps entered into by Vermilion on behalf of the purchaser of the Saskatchewan assets. The contracts were novated upon closing and are presented within discontinued operations. The swaps have an average strike price of CAD $80/bbl with daily volume of 3,175 to 4,540 from Q3 2025 to Q2 2028.

Unrealized foreign exchange gainsor losses

As a result of Vermilion’s international operations, Vermilion has monetary assets and liabilities denominated in currencies other than the Canadian dollar. These monetary assets and liabilities include cash, receivables, payables, long-term debt, derivative instruments and intercompany loans. Unrealized foreign exchange gains and losses result from translating these monetary assets and liabilities from their underlying currency to the Canadian dollar.

In 2025, unrealized foreign exchange gains and losses primarily resulted from:

The translation of Euro and US dollar denominated<br>intercompany loans to and from our international subsidiaries to Vermilion Energy Inc. An appreciation in the Euro and/or the US dollar<br>against the Canadian dollar will result in an unrealized foreign exchange loss (and vice-versa). Under IFRS Accounting Standards, the<br>offsetting foreign exchange loss or gain is recorded as a currency translation adjustment within other comprehensive income. As a result,<br>consolidated comprehensive income reflects the offsetting of these translation adjustments while net earnings (loss) reflects only the<br>parent company's side of the translation.
The translation of our USD denominated<br>2030 senior unsecured notes and USD denominated 2033 senior unsecured notes.
--- ---
The translation of USD borrowings on our<br>revolving credit facility. The unrealized foreign exchange gains or losses on these borrowings are offset by unrealized derivative gains<br>or losses on associated USD-to-CAD cross currency interest rate swaps.
--- ---

For the three months ended September 30, 2025, we recognized a net unrealized foreign exchange loss of $41.2 million, primarily driven by the effects of the US dollar strengthening 2.0% against the Canadian dollar on our US denominated debt combined with the effects of the Euro strengthening 1.9% against the Canadian dollar on our Euro denominated intercompany loans. For the nine months ended September 30, 2025, we recognized a net unrealized foreign exchange loss of $71.5 million, primarily driven by the effects of the Euro strengthening 9.1% against the Canadian dollar on our Euro denominated intercompany loans, partially offset by the impact of the US dollar weakening 3.2% against the Canadian dollar on our US denominated debt.

Accretion

Accretion expense is recognized to update the present value of the asset retirement obligation balance. For the three months ended September 30, 2025, accretion expense increased primarily due to dispositions in Canada and the United States and changes in estimates in Germany, partially offset by the impact of the Euro strengthening against the Canadian dollar. For the nine months ended September 30, 2025, accretion expense increased primarily due to the impact of the Euro strengthening against the Canadian dollar and changes in discount rates, partially offset by lower asset retirement balances due to acquisition and dispositions in Canada and the United States in 2025.

Depletion and depreciation

Depletion and depreciation expense is recognized to allocate the cost of capital assets over the useful life of the respective assets. Depletion and depreciation expense per unit of production is determined for each depletion unit (which are groups of assets within a specific production area that have similar economic lives) by dividing the sum of the net book value of capital assets and future development costs by total proved plus probable reserves.

| Vermilion Energy Inc.  ■  Page 31  ■  2025 Third Quarter Report |

| --- |

Fluctuations in depletion and depreciation expense are primarily the result of changes in produced crude oil and natural gas volumes, and changes in depletion and depreciation per unit. Fluctuations in depletion and depreciation per unit are the result of changes in reserves, depletable base (net book value of capital assets and future development costs), and relative production mix.

Depletion and depreciation on a per boe basis for the three and nine months ended September 30, 2025 of $15.66 and $16.42 decreased from $22.78 and $22.04 in the same periods of the prior year primarily due to the reserves and future development costs added as part of the Westbrick acquisition and increased reserves at Mica. The decrease was partially offset by the strengthening of the Euro against the Canadian dollar.

Deferred tax

Deferred tax assets arise when the tax basis of an asset exceeds its accounting basis (known as a deductible temporary difference). Conversely, deferred tax liabilities arise when the tax basis of an asset is less than its accounting basis (known as a taxable temporary difference). Deferred tax assets are recognized only to the extent that it is probable that there are future taxable profits against which the deductible temporary difference can be utilized. Deferred tax assets and liabilities are measured at the enacted or substantively enacted tax rate that is expected to apply when the asset is realized, or the liability is settled.

As such, fluctuations in deferred tax expenses and recoveries primarily arise as a result of: changes in the accounting basis of an asset or liability without a corresponding tax basis change (e.g. when derivative assets and liabilities are marked-to-market or when accounting depletion differs from tax depletion), changes in available tax losses (e.g. if they are utilized to offset taxable income), changes in estimated future taxable profits resulting in a derecognition or recognition of deferred tax assets, and changes in enacted or substantively enacted tax rates.

For the three months ended September 30, 2025, the Company recorded deferred tax expense on continuing and discontinued operations, which was primarily driven by the derecognition of deferred tax assets in Ireland. For the nine months ended September 30, 2025, the Company recorded a net deferred tax expense on continuing operations related to changes in temporary differences in Canada and Ireland, partially offset by a deferred tax recovery on discontinued operations, driven by the impairment recorded attributable to discontinued operations.The deferred tax expense in the prior year was primarily driven by the derecognition of the deferred tax assets in Ireland.

Financial Position Review

Balance sheet strategy

We regularly review whether our forecast of fund flows from operations is sufficient to finance planned capital expenditures, dividends, share buy-backs, and abandonment and reclamation expenditures. To the extent that fund flows from operations forecasts are not expected to be sufficient to fulfill such expenditures, we will evaluate our ability to finance any shortfall by reducing some or all categories of expenditures, with issuances of equity, and/or with debt (including borrowing using the unutilized capacity of our existing revolving credit facility). We have a long-term goal of maintaining a ratio of net debt to four quarter trailing fund flows from operations of approximately 1.0.

As at September 30, 2025, we have a ratio of net debt to four quarter trailing fund flows from operations of 1.4.

Net debt

Net debt is reconciled to long-term debt, as follows:

As at
($M) Sep 30, 2025 Dec 31, 2024
Long-term debt 1,264,343 963,456
Adjusted working capital ^(1)^ 122,068 3,426
Unrealized FX on swapped USD borrowings (1,658)
Net debt 1,384,753 966,882
Ratio of net debt to four quarter trailing fund flows from operations ^(2)^ 1.4 0.8
^(1)^ Adjusted working capital is a non-GAAP financial measure that is not standardized under IFRS Accounting<br>Standards and may not be comparable to similar measures disclosed by other issuers. It is defined as current assets less current liabilities,<br>excluding current derivatives and current lease liabilities. The measure is used to calculate net debt, a capital measure disclosed above.<br>Reconciliation to the primary financial statement measures can be found in the “Non-GAAP and Other Specified Financial Measures”<br>section of this document.
--- ---
^(2)^ Subsequent to February 26, 2025, net debt to four quarter trailing fund flows from operations is calculated<br>inclusive of Westbrick Energy's pre-acquisition four quarter trailing fund flows from operations, as if the acquisition of Westbrick Energy<br>occurred at the beginning of the four-quarter trailing period, and exclusive of the four quarter trailing fund flows from discontinued<br>operations to reflect the Company’s ability to repay debt on a pro forma basis.

| Vermilion Energy Inc.  ■  Page 32  ■  2025 Third Quarter Report |

| --- |

As at September 30, 2025, net debt increased to $1.4 billion (December 31, 2024 - $1.0 billion) primarily due to the financing of the Westbrick acquisition in Q1 2025. The increase was partially offset by the proceeds received from the disposition of the Saskatchewan and United States assets and strong free cash flow generation primarily driven by stronger operational performance from the Westbrick assets acquired.

The ratio of net debt to four quarter trailing fund flows from operations^(1)^ increased to 1.4 as at September 30, 2025 (December 31, 2024 - 0.8) primarily due to higher net debt on acquisition and disposition activity.

Long-term debt

The balances recognized on our balance sheet are as follows:

As at
Sep 30, 2025 Dec 31, 2024
Revolving credit facility 196,872
2025 senior unsecured notes 398,275
2030 senior unsecured notes 519,758 565,181
2033 senior unsecured notes 547,713
Long-term debt 1,264,343 963,456

Revolving credit facility

As at September 30, 2025, Vermilion had in place a bank revolving credit facility maturing May 25, 2029 with terms and outstanding positions as follows:

Consolidated total debt to consolidated EBITDA Less than 4.0 1.07 0.72
Consolidated total senior debt to consolidated EBITDA Less than 3.5 0.17
Consolidated EBITDA to consolidated interest expense Greater than 2.5 9.23 16.59

Our financial covenants include financial measures defined within our revolving credit facility agreement that are not defined under IFRS Accounting Standards. These financial measures are defined by our revolving credit facility agreement as follows:

Consolidated total debt: Includes all amounts<br>classified as “Long-term debt”, “Current portion of long-term debt”, and “Lease obligations” (including<br>the current portion included within "Accounts payable and accrued liabilities" but excluding operating leases as defined under<br>IAS 17) on our consolidated balance sheet.
Consolidated total senior debt: Consolidated<br>total debt excluding unsecured and subordinated debt.

Common shares purchased under the NCIB will be cancelled.

In the third quarter of 2025, Vermilion purchased 0.6 million common shares under the NCIB for total consideration of $6.3 million. The common shares purchased under the NCIB were cancelled.

Subsequent to September 30, 2025, Vermilion purchased and cancelled 0.3 million shares under the NCIB for total consideration of $2.7 million.

Asset Retirement Obligations

As at September 30, 2025, asset retirement obligations were $1.0 billion compared to $1.2 billion as at December 31, 2024. The decrease in asset retirement obligations is primarily attributable to changes in rates combined with the United States and Saskatchewan dispositions, partially offset by the foreign exchange impact of the Euro strengthening against the Canadian dollar and the acquisition of Westbrick asset retirement obligations. The credit spread increased to 4.1% at September 30, 2025 compared to 2.6% at December 31, 2024 primarily due to a higher expected cost of borrowing.

The present value of the obligation is calculated using a credit-adjusted risk-free rate, calculated using a credit spread added to risk-free rates based on long-term, risk-free government bonds. Vermilion's credit spread is determined using the Company's expected cost of borrowing at the end of the reporting period.

The risk-free rates and credit spread used as inputs to discount the obligations were as follows:

Sep 30, 2025 Dec 31, 2024 Change
Credit spread added to below noted risk-free rates 4.1 % 2.6 % 1.5 %
Country specific risk-free rate
Canada 3.7 % 3.2 % 0.5 %

Current cost estimates are inflated to the estimated time of abandonment using inflation rates of between 1.5% and 3.6% (as at December 31, 2024 - between 1.5% and 3.6%).

Risks and Uncertainties


Vermilion is exposed to various market and operational risks. For a discussion of these risks, please see Vermilion's MD&A and Annual Information Form, each for the year ended December 31, 2024 available on SEDAR+ at www.sedarplus.ca or on Vermilion’s website at www.vermilionenergy.com.

Critical Accounting Estimates

The preparation of consolidated financial statements in accordance with IFRS Accounting Standards requires management to make estimates, judgments and assumptions that affect reported assets, liabilities, revenues and expenses, gains and losses, and disclosures of any possible contingencies. These estimates and assumptions are developed based on the best available information which management believed to be reasonable at the time such estimates and assumptions were made. As such, these assumptions are uncertain at the time estimates are made and could change, resulting in a material impact on Vermilion’s consolidated financial statements. Estimates are reviewed by management on an ongoing basis and as a result may change from period to period due to the availability of new information or changes in circumstances. Additionally, as a result of the unique circumstances of each jurisdiction that Vermilion operates in, the critical accounting estimates may affect one or more jurisdictions. There have been no material changes to our critical accounting estimates used in applying accounting policies for the nine months ended September 30, 2025. Further information, including a discussion of critical accounting estimates, can be found in the notes to the Consolidated Financial Statements and annual MD&A for the year ended December 31, 2024, available on SEDAR+ at www.sedarplus.ca or on Vermilion’s website at www.vermilionenergy.com.

Off Balance Sheet Arrangements

We have not entered into any guarantee or off balance sheet arrangements that would materially impact our financial position or results of operations.

Internal Control Over Financial Reporting

There has been no change in Vermilion’s internal control over financial reporting ("ICFR") during the period covered by this MD&A that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Vermilion has limited the scope of design controls and procedures ("DC&P") and internal controls over financial reporting to exclude controls, policies

and procedures of Westbrick Energy Ltd., which was acquired on February 26, 2025. The scope limitation is in accordance with section 3.3(1)(b) of NI 52-109 which allows an issuer to limit the design of DC&P and ICFR to exclude controls, policies, and procedures of a business that the issuer acquired not more than 365 days before the end of the fiscal period.

The table below presents the summary financial information of Westbrick Energy Ltd. included in Vermilion's financial statements as at and for the three and nine months ended September 30, 2025:

($M) Balance at September 30, 2025
Non-current assets 1,213,496
Non-current liabilities (187,799)

Recently Adopted Accounting Pronouncements

Vermilion did not adopt any new accounting pronouncements as at September 30, 2025 that would have a material impact on the Consolidated Interim Financial Statements.

Regulatory Pronouncements Not Yet Adopted

Issuance of IFRS Sustainability Standards - IFRS S1 "GeneralRequirements for Disclosure of Sustainability-related Financial Information" and IFRS S2 "Climate-related Disclosures"and European Corporate Sustainability Reporting Directive (CSRD)

In June 2023, the International Sustainability Standards Board (ISSB) issued its inaugural standards - IFRS S1 and IFRS S2.

The Canadian Sustainability Standards Board has released Canada-specific version of IFRS S1 and S2 as Canadian Sustainability Disclosure Standards 1 and 2. While Canadian securities regulators have not mandated these standards, they have referenced them as a useful voluntary disclosure framework for sustainability and climate-related disclosure, and noted that securities legislation already requires issuers to disclose material climate-related risks. Australia has mandated the Australian version of IFRS S2 as Australian Sustainability Reporting Standards 2 with mandatory disclosure anticipated for Vermilion in in either 2026 or 2027, depending on quantity of emissions. While the EU implemented the CSRD and its related European Sustainability Reporting Standards (ESRS) in 2024, these are now under potential revision by the Omnibus legislation, which has delayed Vermilion’s reporting date from 2025 to potentially 2027 or 2028, depending on the final provisions of the Omnibus. Vermilion is continuing to review the impact of the standards on its financial reporting.

IFRS 18 “Presentation and Disclosure in FinancialStatements issued”

In April 2024, the IASB issued IFRS 18 Presentation and Disclosure in Financial Statements issued which will replace IAS 1 Presentation of Financial Statements. Retrospective application of the standard is mandatory for annual reporting periods starting from January 1, 2027 onwards with earlier application is permitted. Vermilion is assessing the impacts of the standard on its financial reporting.

Disclosure Controls and Procedures

Our officers have established and maintained disclosure controls and procedures and evaluated the effectiveness of these controls in conjunction with our filings. As of September 30, 2025, we have evaluated the effectiveness of the design and operation of our disclosure controls and procedures. Based on this evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded and certified that our disclosure controls and procedures are effective.

Under National Instrument 51-101 "Standards of Disclosure for Oil and Gas Activities", disclosure of production volumes should include segmentation by product type as defined in the instrument. This table provides a reconciliation from "crude oil and condensate", "NGLs" and "natural gas" to the product types. In this report, references to "crude oil" and "light and medium crude oil" mean "light crude oil and medium crude oil" and references to "natural gas" mean "conventional natural gas". Production volumes reported are based on quantities as measured at the first point of sale.

Non-GAAP and Other Specified Financial Measures


This MD&A includes references to certain financial measures which do not have standardized meanings and may not be comparable to similar measures presented by other issuers. These financial measures include fund flows from operations, a total of segments measure of profit or loss in accordance with IFRS 8 “Operating Segments” (please see Segmented Information in the Notes to the condensed Consolidated Interim Financial Statements) and net debt, a capital management measure in accordance with IAS 1 “Presentation of Financial Statements” (please see Capital Disclosures in the Notes to the condensed Consolidated Interim Financial Statements).

In addition, this MD&A includes financial measures which are not specified, defined, or determined under IFRS Accounting Standards and are therefore considered non-GAAP financial measures and may not be comparable to similar measures presented by other issuers. These non-GAAP financial measures include:

Total of Segments Measure

Fund flows from operations (FFO): Most directly comparable to net earnings (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 are most directly comparable to net earnings (loss) from continuing operations and net earnings (loss) discontinued operations, respectively.

Non-GAAP Financial Measures and Non-GAAP Ratios

Fund flows from operations perbasic and diluted share: FFO per 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 perboe: 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.

Free cash flow (FCF): 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. 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. Reconciliation to the primary financial statement measures can be found in the following table.

Capital expenditures: 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.

**Payout and payout % of FFO:**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.

Return on capital employed (ROCE): A non-GAAP ratio**,** 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 earnings (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.

Average capital employed 5,513,299 5,995,108
Return on capital employed (3) % (13) %

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

Current derivative liability ^(1)^ 7,180 52,944
Adjusted working capital (deficit) (122,068) (3,426)

Acquisitions: 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.

Operating netback: 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 earnings (loss). Management assesses operating netback as a measure of the profitability and efficiency of our field operations.

Net debt to four quarter trailingfund flows from operations: 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 and is calculated as net debt (capital management measure) divided by fund flows from operations (total of segments measure) from the preceding four quarters.

Capital Management Measure

Net debt: 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 and current lease liabilities), and represents Vermilion's net financing obligations after adjusting for the timing of working capital fluctuations.

Description of equity reserves

Shareholders’ capital

Represents the recognized amount for common shares issued (net of equity issuance costs and deferred taxes) less the weighted-average carrying value of shares repurchased. The price paid to repurchase common shares is compared to the carrying value of the shares and the difference is recorded against deficit.

Contributed surplus

Represents the recognized value of unvested equity based awards that will be settled in shares. Once vested, the value of the awards are transferred to shareholders’ capital.

Accumulated other comprehensive income

Represents currency translation adjustments, hedge accounting reserve and fair value adjustments on investments.

Currency translation adjustments result from translating the balance sheets of subsidiaries with a foreign functional currency to Canadian dollars at period-end rates. These amounts may be reclassified to net earnings (loss) if there is a disposal or partial disposal of a subsidiary.

The hedge accounting reserve represents the effective portion of the change in fair value related to cash flow and net investment hedges recognized in other comprehensive income, net of tax and reclassified to the consolidated statement of net earnings (loss) in the same period in which the transaction associated with the hedged item occurs.

Fair value adjustment on investment in securities, net of tax, are a result of changes in the fair value of investments that have been elected to be subsequently measured at fair value through other comprehensive income.

Deficit

Represents the cumulative net earnings (loss) less distributed earnings and surplus of the price paid to repurchase common shares of Vermilion Energy Inc. over the weighted-average carrying value of the shares repurchased.

Westbrick Energy Ltd

On February 26, 2025, Vermilion purchased 100% of the shares outstanding of Westbrick Energy Ltd. ("Westbrick" or "Westbrick Energy") a private company with assets located adjacent to Vermilion's existing Alberta assets for total consideration of $1.1 billion, including 1,104,357 shares of Vermilion valued at $12.10 per share for an aggregate $13.4 million in fair value share consideration upon closing, with the balance paid in cash. Total transaction costs included in Vermilion's general and administrative expenses for the nine months ended September 30, 2025 related to the acquisition are approximately $8.3 million ($0.8 million in the year ended December 31, 2024).

The total consideration paid and the fair value of the assets acquired and liabilities assumed at the date of acquisition are detailed in the table below:

Consideration
Cash consideration paid 1,089,805
Share consideration 13,363
Total consideration paid 1,103,168
Allocation of consideration
Cash acquired 6,159
Capital assets 1,185,212
Exploration and evaluation assets 129,578
Acquired working capital deficit (36,555)
Derivative asset 13,376
Lease liability (3,434)
Asset retirement obligations (46,190)
Deferred tax liability (144,978)
Net assets acquired 1,103,168

The results of operations from the assets acquired and liabilities assumed have been included in Vermilion's condensed consolidated interim financial statements beginning February 26, 2025 and have contributed revenues net of royalties of $203.4 million and net earnings of $7.1 million. Had the acquisition occurred on January 1, 2025, consolidated petroleum and natural gas revenue net of royalties and net earnings would have increased by $58.9 million and $15.6 million, respectively, to $1,334.2 million and consolidated net loss of $200.3 million for the nine months ended September 30, 2025.

Vermilion acquired contractual obligations and commitments as part of the Westbrick acquisition completed on February 26, 2025. Please refer to Note 13 "Supplemental Information" for a summary of the Company's contractual obligations and commitments as at September 30, 2025.

Adoption of accounting policy - Assets held for saleand discontinued operations

The Company classifies capital assets and exploration and evaluation assets as held for sale if it is highly probable their carrying amounts will be recovered through a disposition rather than through future operating cash flows. This condition is met when the sale is highly probable, the asset is available for immediate sale in its present condition and the sale is expected to be completed within one year from the date of classification. Assets held for sale are measured at the lower of the carrying amount and recoverable amount, with impairments or impairment reversals recognized in the consolidated statements of net earnings and comprehensive income.

Assets held for sale are classified as current assets and are not subject to depletion and depreciation. Decommissioning, lease and derivative liabilities associated with assets held for sale are classified as current liabilities.

Upon classification, the Company assesses whether the assets held for sale represent a major component of the business. If this criteria is met, the operating results attributable to the assets held for sale are presented as discontinued operations, with prior periods reclassified to conform with current period presentation.

Saskatchewan and Manitoba

On May 23, 2025 Vermilion announced it had entered into an agreement for the sale of the Saskatchewan and Manitoba assets. On July 10, 2025, Vermilion closed the sale for net proceeds of $392.6 million. Following the announcement, the sale was considered to be highly probable and therefore the assets and liabilities associated with the disposal group were reclassified to held for sale and measured at the lower of their carrying amount and fair value less costs to sell with resulting impairment of $230.9 million. The closing of the sale resulted in the derecognition of the net assets held for sale and $11.0 million of derivative liabilities, and a gain on disposition of $2.5 million, recognized in other expense within net earnings (loss) from discontinued operations. The book value of the net assets disposed was $379.0 million.

United States

On June 5, 2025, Vermilion announced it had entered into an agreement for the sale of the United States assets. On July 31, 2025, Vermilion closed the sale for net proceeds of $90.9 million, before an additional US $7.0 million of contingent payments. Following the announcement, the sale was considered to be highly probable and therefore the assets and liabilities associated with the disposal group were reclassified to held for sale and measured at the lower of their carrying amount and fair value less costs to sell with resulting impairment of $141.5 million. The closing of the sale resulted in derecognition of the net assets held for sale and a loss on disposition of $6.5 million, recognized in other expense within net earnings (loss) from discontinued operations. The book value of the net assets disposed was $97.5 million.

The following table reconciles the book value of the net assets disposed of as at September 30, 2025:

The following table summarizes the net assets of CEI based on their most recent and publicly available financial statements as at June 30, 2025, and Vermilion's respective share:

Current assets 6,439
Non-current assets 239,100

Non-current liabilities (27,985)
Net assets 163,628
Vermilion's ownership 20.7 %
Vermilion's share of net assets 33,833

In February 2024, Vermilion acquired additional securities, increasing its ownership to approximately 21% of the issued and outstanding common shares of CEI. As such, Vermilion concluded it had acquired significant influence over the entity and should prospectively be accounted for using the equity method of accounting subsequently, recording Vermilion's share of CEI's profit or loss. Prior to acquiring significant influence, this investment was accounted for under IFRS 9 as an investment in securities using the fair value method of accounting. The transaction was treated as a disposal of the original investment at fair value and an acquisition of an investment in associate, with no resulting gain or loss recognized in the consolidated statement of net earnings.

For the nine months ended September 30, 2025 and the seven months ended September 30, 2024 after acquiring significant influence over the entity, Vermilion adjusted the value of the investment for its share of CEI's profit or loss. The following table summarizes CEI's estimated revenue and net loss and Vermilion's respective share, based on CEI's most recent and publicly available financial statements and other market factors, including but not limited to, relevant market prices:

Net loss (11,449) (5,313)
Vermilion's ownership 20.7 % 20.8 %
Vermilion's share of net loss (2,370) (1,104)

At September 30, 2025, the fair value of Vermilion's investment in CEI is $90.3 million or $0.82/share (December 31, 2024 - $88.1 million or $0.80/share).

9. Capital disclosures

Vermilion defines capital as net debt and shareholders' capital. Net debt consists 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 and current lease liabilities). In managing capital, Vermilion reviews whether fund flows from operations is sufficient to fund capital expenditures, dividends, share buybacks, and asset retirement obligations.

The following table calculates Vermilion’s ratio of net debt to four quarter trailing fund flows from operations:

Sep 30, 2025 Dec 31, 2024
Long-term debt 1,264,343 963,456
Adjusted working capital ^(1)^ 122,068 3,426
Unrealized FX on swapped USD borrowings (1,658)
Net debt 1,384,753 966,882
Ratio of net debt to four quarter trailing fund flows from operations ^(2)^ 1.4 0.8
^(1)^ Adjusted working capital is defined as current assets (excluding current derivatives), less current liabilities<br>(excluding current derivatives and current lease liabilities).
--- ---
^(2)^ Subsequent to February 26, 2025, net debt to four quarter trailing fund flows from operations is calculated<br>inclusive of Westbrick Energy's pre-acquisition four quarter trailing fund flows from operations, as if the acquisition of Westbrick Energy<br>occurred at the beginning of the four-quarter trailing period, and exclusive of the four quarter trailing fund flows from discontinued<br>operations to reflect the Company’s ability to repay debt on a pro forma basis.
