NOTES TO THE CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS
For the nine months ended September 30, 2025
(All tabular amounts are in thousands of United States dollars unless otherwise stated)
(Unaudited)

1 Nature of operations

B2Gold Corp. (“B2Gold” or the “Company”) is a Vancouver-based gold producer with four operating mines: the Fekola Mine in Mali, the Masbate Mine in the Philippines, the Otjikoto Mine in Namibia and the Goose Mine in Canada. The Company determined that the Goose Mine achieved commercial production on October 2, 2025. The Company also owns the Gramalote Project in Colombia. The Company holds an approximately 33% interest in Versamet Royalties Corporation ("Versamet") and a portfolio of evaluation and exploration assets in a number of countries including Mali and Finland.

B2Gold is a public company which is listed on the Toronto Stock Exchange under the symbol “BTO”, the NYSE American LLC under the symbol “BTG” and the Namibian Stock Exchange under the symbol “B2G”. B2Gold’s head office is located at Suite 3400, Park Place, 666 Burrard Street, Vancouver, British Columbia, V6C 2X8.

2 Basis of preparation

These condensed interim consolidated financial statements have been prepared in accordance with International Accounting Standard 34, Interim Financial Reporting ("IAS 34"), as issued by the International Accounting Standards Board ("IASB"). These condensed interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2024, which have been prepared in accordance with IFRS Accounting Standards as issued by the International Accounting Standards Board ("IFRS").

These condensed interim consolidated financial statements follow the same accounting policies and methods of application as the most recent annual consolidated financial statements of the Company except as noted below.

These condensed consolidated interim financial statements were authorized for issue by the Board of Directors ("Board") on November 5, 2025.

Recent IFRS pronouncements issued

IFRS 18, Presentation and disclosure in financial statements

In April 2024, the IASB issued IFRS 18 Presentation and Disclosure in the Financial Statements (“IFRS 18”) replacing IAS 1 Presentation of Financial Statements. IFRS 18 introduces new requirements for presentation within the statement of operations, including specified totals and subtotals. IFRS 18 is effective for annual reporting periods beginning on or after January 1, 2027, and is to be applied retrospectively, with early adoption permitted. The Company is currently assessing the impact of the standard on its consolidated financial statements.

Amendments to IFRS 9 and IFRS 7

In May 2024, the IASB issued narrow scope amendments to IFRS 9 Financial Instruments and IFRS 7 Financial Instruments: Disclosures. The amendments include the clarification of the date of initial recognition or derecognition of financial liabilities, including financial liabilities that are settled in cash using an electronic payment system. The amendments are effective for annual periods beginning on or after January 1, 2026, with early application permitted. The Company is currently assessing the impact of the standard on its consolidated financial statements.

3 Significant accounting judgements and estimates

The preparation of these financial statements in conformity with IAS 34 requires judgements and estimates that affect the amounts reported. Those judgements and estimates concerning the future may differ from actual results. The following are the areas of accounting policy judgement and accounting estimates applied by management that most significantly affect the Company’s financial statements, including those areas of estimation uncertainty that could result in a material adjustment to the carrying amounts of assets and liabilities within the next financial year.

Areas of judgement

Assessment of impairment and reversal of impairment indicators for long-lived assets

The Company applies significant judgement in assessing whether there are indicators of impairment or impairment reversal present that give rise to the requirement to conduct an impairment test. Internal and external factors such as significant changes in the use of the asset, legal and permitting factors, future gold prices, operating and capital cost forecasts, quantities of mineral reserves and resources, and movements in market interest rates are used by management in determining whether there are any indicators.

B2GOLD CORP.
NOTES TO THE CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS
For the nine months ended September 30, 2025
(All tabular amounts are in thousands of United States dollars unless otherwise stated)
(Unaudited)

Uncertain tax positions

The Company’s operations involve the application of complex tax regulations in multiple international jurisdictions. Determining the tax treatment of a transaction requires the Company to apply judgement in its interpretation of the applicable tax law. These positions are not final until accepted by the relevant tax authority. The tax treatment may change based on the result of assessments or audits by the tax authorities often years after the initial filing.

The Company recognizes and records potential liabilities for uncertain tax positions based on its assessment of the amount, or range of amounts of tax that will be due. The Company adjusts these accruals as new information becomes available. Due to the complexity and uncertainty associated with certain tax treatments, the ultimate resolution could result in a payment that is materially different from the Company’s current estimate of the tax liabilities.

Sources of estimation uncertainty

Fair value of financial instruments

The fair value of financial instruments that are not traded in an active market are determined using valuation techniques. In determining the fair value of the Company's gold collars and gold stream obligation (Notes 14, 15 and 17), the Company makes significant assumptions that are based on the underlying models and the market conditions existing at both initial recognition and the end of each reporting period.

Mineral reserve and resource estimates

Mineral reserves are estimates of the amount of ore that can be economically and legally extracted from the Company’s mining properties. The Company estimates its mineral reserves and mineral resources based on information compiled by appropriately qualified persons relating to the geological data on the size, depth and shape of the ore body, and requires complex geological judgements to interpret the data. The estimation of recoverable reserves is based upon factors such as estimates of foreign exchange rates, commodity prices, future capital requirements, metallurgical recoveries, permitting and production costs along with geological assumptions and judgements made in estimating the size, and grade of the ore body. Changes in the reserve or resource estimates may impact the carrying value of mining interests, mine restoration provisions, recognition of deferred tax assets, depreciation and amortization charges and royalties receivable.

Impairment of long-lived assets

Long-lived assets are tested for impairment, or reversal of a previous impairment, if there is an indicator of impairment or a subsequent reversal. Calculating the estimated recoverable amount of cash-generating units for long-lived asset requires management to make estimates and assumptions that include such factors as mineable mineralization including reserves and resources, future production levels, operating and capital costs, application of royalty, income tax and mining tax rates, future metal prices and discount rates. Changes in any of these assumptions or estimates used in determining the recoverable amount could impact the analysis. Such changes could be material.

Value-added tax receivables

The Company incurs indirect taxes, including value-added tax, on purchases of goods and services at its operating mines and development project. Indirect tax balances are recorded at their estimated recoverable amounts within current or long-term assets, net of provisions, and reflect the Company’s best estimate of their recoverability under existing tax rules in the respective jurisdictions in which they arise. Management’s assessment of recoverability considers the probable outcomes and expected timing of claimed deductions and/or disputes. The provisions and balance sheet classifications made to date may be subject to change and such change may be material.

Long-term value-added tax receivables as at September 30, 2025 included amounts for the Fekola Mine of $280 million (December 31, 2024 - $214 million), for the Masbate Mine of $23 million (December 31, 2024 – $13 million), and for the Gramalote Project of $20 million (December 31, 2024 - $17 million).

Current and deferred income taxes

The Company is periodically required to estimate the tax basis of assets and liabilities. Where applicable tax laws and regulations are either unclear or subject to varying interpretations, it is possible that changes in these estimates could occur that materially affect the amounts of deferred income tax assets and liabilities recorded in the financial statements. Changes in deferred tax assets and liabilities generally have a direct impact on earnings in the period that the changes occur.

Each period, the Company evaluates the likelihood of whether some portion or all of each deferred tax asset will not be realized. This evaluation is based on historic and future expected levels of taxable income and the associated repatriation of retained earnings, the pattern and timing of reversals of taxable temporary timing differences that give rise to deferred tax liabilities, and tax planning initiatives. Levels of future taxable income are affected by, among other things, metal prices, production costs, quantities of proven and probable gold reserves, interest rates and foreign currency exchange rates. The availability of retained earnings for distribution depends on future levels of taxable income as well as future reclamation expenditures, capital expenditures, dividends and other uses of available cash flow.

Impairment of the Fekola Complex CGU

During the year ended December 31, 2023, the State of Mali ("the State") introduced a new mining code (the “2023 Mining Code”) and related Local Content Law. In July 2024, the accompanying Implementation Decrees which clarified how the provisions of the 2023 Mining Code and Local Content Law applied were enacted into law. The Company’s analysis concluded that the Fekola Complex CGU was impaired resulting in an impairment of $215 million. A net impairment charge of $194 million after taking into account a deferred income tax recovery of $21 million was recorded in the Condensed Interim Consolidated Statement of Operations for the nine months period ended September 30, 2024. On September 11, 2024, the Company reached a Memorandum of Understanding (the "Agreement") with the State which covers the ongoing operation and governance of the Fekola Complex as well as the settlement of existing income tax, customs and other regulatory disputes covering the period 2016 to December 31, 2023 and the distribution of dividends attributed to the State of Mali up to December 31, 2023.

Principal terms of the agreement:
Settlement of income tax and customs assessments for the period from 2016 through 2023 of $70 million. An expense of $67 million (net of previous accruals) was recorded as an income tax expense in the Condensed Interim Consolidated Statement of Operations for the nine months ended September 30, 2024 (the expense for the three months ended September 30, 2024 was $30 million).
Settlement of other regulatory disputes related to the timing of repatriation of funds of $17 million. This amount was paid upon signing of the Agreement and was recorded in Other Expense in the Condensed Interim Consolidated Statement of Operations for the three and nine months ended September 30, 2024.
Upon completion of certain conditions precedent, the State of Mali's ordinary share interest in Fekola was converted into a 10% preferred share interest. The rights of the additional preferred share interest are consistent with the State of Mali's 10% free carried interest including priority dividend rights, therefore, this is accounted for as an income tax under IAS 12 Income taxes.
In addition to the above, the Company agreed to forgive the principal and accrued interest balance outstanding totalling $69 million on the loan made to the State for the purchase of their 10% ordinary share ownership. This was recorded within Equity on the Condensed Interim Consolidated Balance Sheet.

Upon completion of the second tranche, on August 13, 2024, the Company received an additional 17 million Versamet shares at Cdn. $0.80 per share for estimated proceeds of $10 million. The Company recorded a $49 million gain on sale of mining interests in the Condensed Interim Consolidated Statement of Operations for the nine months period ended September 30, 2024.

(Unaudited)
The initial conversion rate is subject to adjustment in certain events. In addition, if certain fundamental changes occur, including a change in control or upon notice of redemption by the Company as described below, the holders may elect to convert the Notes. In the event of a fundamental change, the holders may elect to convert any outstanding Notes at a cash purchase price equal to 100% of the principal amount plus accrued and unpaid interest.

A fundamental change includes the following occurrences:
A change in control where a person or group becomes the beneficial owner of more than 50% of our voting stock, or gains the power to elect a majority of our board of directors.
The consummation of significant transactions such as certain mergers or consolidations pursuant to which our common shares will be converted or exchanged for cash, securities or other property, or sales of substantially all our assets that change the corporate structure or ownership.
Approval by our shareholders of any plan for liquidation or dissolution.

Prior to February 7, 2028, the Company may not redeem the notes except in the event of certain changes in Canadian tax law. At any time on or after February 7, 2028, and until maturity, the Company may redeem all or part of the Notes for cash if the price of the Company’s common shares for at least 20 trading days in a period of 30 consecutive trading days, ending on the trading day prior to the date of notice of redemption, exceeds 130% of the conversion price in effect on each such day. The redemption price is equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest. This option was not separated as it is considered closely related to the underlying instrument.

The Notes are the Company's senior unsecured obligations and rank equally with all existing and future senior unsecured indebtedness. The Notes are effectively unsecured to all of the Company's existing and future secured indebtedness to the extent of the value of the collateral securing such indebtedness. The Notes are structurally unsecured to all existing and future liabilities, including trade payables, of the Company's subsidiaries.

The Notes are compound financial instruments consisting of a financial liability and a conversion option that is classified as equity. Of the gross proceeds of $460 million, $365 million was allocated to the liability component, representing the fair value of the liability component on initial recognition, calculated as the present value of the contractual principal and interest payments over the term of the Notes using a discount rate of 7.8%. Total financing costs of $14 million were allocated to the liability and equity components in proportion to the allocation of the gross proceeds, with $11 million allocated to the liability and $3 million allocated to equity. The net liability of $354 million ($365 million net of $11 million of financing costs) will be accreted to the face value of the Notes over the term to maturity using the effective interest method with an effective interest rate of 8.5%.

The equity component, representing the holders’ conversion option, was allocated the residual amount of $95 million. The net amount recorded in the Condensed Interim Consolidated Statement of Changes in Equity at September 30, 2025 was $67 million calculated as $95 million option valuation less $3 million of allocated financing costs and a deferred tax charge of $25 million for the taxable temporary difference arising from the difference between the initial carrying amount of the liability component of the Notes and the tax base.

In connection with the Notes, the Company entered into a cash settled total return swap with one of the initial purchasers of the Notes for common shares of the Company with a total value of $50 million. During the nine months ended September 30, 2025, the Company settled the total return swap for a gain of $8 million. This gain was recorded as part of Losses on derivative instruments in the Condensed Interim Consolidated Statements of Operations for the three and nine months ended September 30, 2025.

Revolving credit facility

The Company has an $800 million revolving credit facility ("RCF") with a syndicate of international banks. The RCF allows for an accordion feature whereby upon receipt of additional binding commitments, the facility may be further increased to $1 billion any time prior to the maturity date of December 17, 2028. During the nine months ended September 30, 2025, the Company drew down $400 million and repaid $200 million on the on the RCF. As at September 30, 2025, the Company had available undrawn capacity of $600 million. The Company has provided security on the RCF in the form of a general security interest over the Company’s assets and pledges creating a charge over the shares of certain of the Company’s direct and indirect subsidiaries. In connection with the RCF, the Company must also maintain an interest coverage ratio greater than or equal to 3:1 for any fiscal quarter and a leverage ratio of less than 3.5:1 for any fiscal quarter. As at September 30, 2025, the Company was in compliance with these debt covenants.

15 Gold stream obligation

The Company's gold stream obligation requires the delivery from production at the Company's Goose Mine as follows:
2.7805% of gold production up to delivery of 87,100 ounces;
1.4405% of gold production up to an aggregate of 134,000 ounces; and
1.005% of gold production thereafter.

The gold stream obligation was determined to be a derivative liability under IFRS 9 Financial instruments, and has been classified as FVTPL. As a result, it has been recorded at its fair value on the Condensed Interim Consolidated Balance Sheet with changes in the fair value being recorded in the Condensed Interim Consolidated Statement of Operations. The fair value of the gold stream was determined to be level 3 in the fair value hierarchy (Note 17). The Company has guaranteed the gold stream obligation.

During the three and nine months ended September 30, 2025, the Company delivered 95 ounces (2024 - 0 ounces) into the gold stream obligation. The Company receives purchase price for each ounce of refined gold metal equal to 18% of the p.m. London Bullion Market Association ("LBMA") Gold Price. The difference between the LBMA gold price and such purchase price being payable is deducted against the upfront funding until it has been reduced to nil.

16 Prepaid gold sales

On January 23, 2024, the Company entered into a series of prepaid gold sales with a number of its RCF syndicate banks. Under the terms of the prepaid gold sales, the Company received an upfront payment of $500 million, based on gold forward curve prices averaging approximately $2,191 per ounce, in exchange for equal monthly deliveries of gold from July 2025 to June 2026 totaling 264,768 ounces. Gold deliveries can be from production from any of the Company’s operating mines and the prepaid gold sales can be settled prior to maturity through accelerated delivery of the remaining deliverable gold ounces.

During the three and nine months ended September 30, 2025, the Company delivered 66,192 ounces into contracts valued at $144 million. As the Company physically delivered ounces into the contracts, the portion of the Prepaid Sales relating to the delivered ounces was recognized as gold revenue in the Interim Condensed Consolidated Statement of Operations at the time of delivery based on the contract price.

The following is a summary of the changes in the prepaid gold sales obligation:

During the three and nine months ended September 30, 2025, the Company recognized interest charges of $9 million and $29 million, respectively (2024 - expense of $10 million and $28 million, respectively) relating to the financing component contained in the prepaid gold sales. The interest expense recognized in the Condensed Interim Consolidated Statement of Operations for the three and nine months ended September 30, 2025 was $0 million and $0 million (2024 - $2 million and $11 million) respectively. During the three and nine months ended September 30, 2025, a total of $9 million and $29 million, respectively, was capitalized to the cost of constructing qualifying assets during the period (2024 - $8 million and $17 million, respectively).

17 Financial instruments

The Company’s financial assets and liabilities are classified based on the lowest level of input significant to the fair value measurement based on the fair value hierarchy:

Level 1 – quoted prices in active markets for identical assets or liabilities;

Level 2 – inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and

Level 3 – inputs for the asset or liability that are not based on observable market data.

As at September 30, 2025, the Company’s financial assets and liabilities that are measured at fair value are categorized as follows:

Gold stream obligation (Note 15)

The Company’s long-term investments consist of shares of publicly traded mining companies. The fair values of these were determined using market quotes from an active market for each investment.

The fair values of the Company's fuel and gold derivative contracts were determined using prevailing market rates for instruments with similar characteristics.

The fair value of the gold stream was calculated based on an income approach and a discounted cash flow model. The calculated fair value includes inputs that are based on observable market data, including forward gold price curves and credit adjusted risk-free rates. The fair value also includes inputs that are not based on observable market data, including the timing of future gold deliveries. The valuation has been prepared by an independent valuations specialist with direct oversight from the Company. Forward gold price estimates ranged from $3,825 to $5,182 per ounce. A $100 per ounce change in the gold forward price would have approximately a $5 million impact on the fair value of the gold stream obligation. A 50 basis point change in the discount rate would also have approximately a $5 million impact on the fair value of the gold stream obligation.

The fair value of the Notes, based on quoted market prices, is $778 million. The carrying amount of the Notes represents the liability component recorded at amortized costs (Note 10), while the fair value represents both the liability and equity components. The fair value of the Notes is categorized as level 1 in the fair value hierarchy outlined in IFRS 13 Fair value measurement. The fair value of the Company's other long-term debt approximates its carrying value as it has a floating interest rate and the Company's credit spread has remained approximately consistent. The fair value of the Company's other financial instruments approximate their carrying value due to their short-term nature.

Credit risk

The Company’s maximum exposure to credit risk is the book value of cash and cash equivalents, accounts receivable, loans receivable and the carrying value of its derivative portfolio. The Company limits its credit exposure on cash and cash equivalents by holding its deposits mainly with high credit quality financial institutions as determined by credit rating agencies. The Company maintains its excess cash balances in short-term investments accounts. The Company does not maintain insurance for its cash balances.
