Accounting policies

These interim condensed consolidated financial statements have been prepared under the historical cost convention as modified by the revaluation of certain financial instruments measured at fair value.

The accounting policies and methods of computation applied are consistent with those adopted and disclosed in the Group's consolidated financial statements for the year ended 31 December 2025, with the exception of new accounting pronouncements, which became effective on 1 January 2026 and have been adopted by the Group. The adoption of these new accounting pronouncements has not had a significant impact on the accounting policies, methods of

computation or presentation applied by the Group.

New accounting standards and amendments

The following amendments became effective for annual reporting periods beginning on or after 1 January 2026 and have been adopted by the Group:

• Amendments to the Classification and Measurement of Financial Instruments (Amendments to IFRS 9 Financial Instruments and IFRS 7 Financial Instruments: Disclosures);
• Annual Improvements to IFRS Accounting Standards - Volume 11; and
• Contracts Referencing Nature-dependent Electricity (Amendments to IFRS 9 and IFRS 7).

The adoption of these amendments has not had a significant impact on the Group's accounting policies, methods of computation or the presentation of these interim condensed consolidated financial statements.

Going concern

In assessing its going concern status, the Group has taken account of its financial position, anticipated future trading performance, its borrowings and other available credit facilities, its forecast compliance with covenants on those borrowings and capital expenditure commitments and plans.

The Board is satisfied that the Group's forecasts and projections, having taken account of reasonably possible changes in trading performance, show that the Group has adequate resources to continue in operational existence for at least the next 12 months from the date of this report and that it is appropriate to adopt the going concern basis in preparing these interim condensed consolidated financial statements.

Functional and presentation currency

The functional currency for each entity in the Group is determined as the currency of the primary economic environment in which it operates. The functional currency of the Group's principal operating subsidiaries in Kazakhstan is the Kazakhstani tenge (KZT). The functional currency of the Company is Kazakhstani tenge, determined based on the currency of the primary economic environment in which the Company operates.

The Group has chosen to present its consolidated financial statements in millions of US Dollars (US$m), as management believes it is the most useful presentation currency for international users of the consolidated financial statements of the Group as being common presentation currency in the mining industry.

Exchange rates

Exchange rates used in the preparation of the interim condensed consolidated financial statements were as follows (based on information provided by National Bank of Kazakhstan):

The Group's operating segments are aligned to those production hubs that are evaluated regularly by the chief operating decision maker (the CODM) in deciding how to allocate resources and in assessing performance.

Therefore, the Group has identified two reportable segments:

• Varvara (Varvarinskoye LLC, Komarovskoye Mining Company LLC); and
• Kyzyl (Bakyrchik Mining Venture LLP).

Ertis POX, as well as minor companies and activities (management, exploration and other companies) which do not meet the reportable segment criteria are disclosed within the corporate and other segment.

The measure which management and the CODM use to evaluate the performance of the Group is a segment Adjusted EBITDA, which is an Alternative Performance Measure (APM). For more information on the APMs used by the Group, including definitions, please refer to page 41.

The accounting policies of the reportable segments are consistent with those of the Group's accounting policies under IFRS. Revenue and cost of sales of the production entities are reported net of any intersegmental revenue and cost of sales, related to the intercompany sales of ore and concentrates.

Business segment current assets and liabilities, other than current inventory, are not reviewed by the CODM and therefore are not disclosed in these interim condensed consolidated financial statements. The segment adjusted EBITDA reconciles to the profit before income tax from continuing operations as follows:

Revenue growth was driven by third-party concentrate processing and respective sales recovery as well as higher gold prices.

Revenue analysed by geographical regions of customers is presented below:

Included in revenues for the six months ended 30 June 2026 is revenue from two customers that individually accounted for more than 10% of the Group's total revenue. Revenue from these two largest customers comprised US$ 565 million (US$ 234 million from Kyzyl sales, US$ 331 million from Varvara sales) and US$ 345 million (relating to Kyzyl sales) respectively.

For the six months ended 30 June 2025 revenue from the three largest customers comprised US$ 193 million (US$ 187 million from Varvara sales, US$ 6 million from Varvara sales), US$ 65 million (from Varvara sales) and US$ 40 million (relating to Kyzyl sales).

Presented below is an analysis by revenue streams:

Presented below is an analysis by revenue streams:

Depletion and depreciation of operating assets excludes depreciation relating to non-operating assets (included in general, administrative and selling expenses) and depreciation related to assets employed in development projects where the charge is capitalised. Depreciation expense, which is excluded in the Group's calculation of Adjusted EBITDA (see Note 2), also excludes amounts absorbed into unsold metal inventory balances.

Interest expense on borrowings excludes borrowing costs capitalised in the cost of qualifying assets of US$ 5 million during the six months ended 30 June 2026 (30 June 2025: US$ 1 million). These amounts were calculated based on the Group's general borrowing pool and by applying an effective annualised interests rates of 5.61% and 6.01%, respectively, to cumulative expenditure on such assets.

Income tax for the six months ended 30 June 2026 is charged at 26%, representing the best estimate of the average annual effective tax rate expected for the full year, applied to the pre-tax income of the six month period.

No deferred tax liabilities for taxes that would be payable on the unremitted earnings of the Group subsidiaries was recognised as of 30 June 2026 as the Group determined that the undistributed profit of its subsidiaries would not be distributed in the foreseeable future (judged to be one year).

The Group has applied the exception available under the amendments to IAS 12 published by the IASB in May 2023 and does not recognise or disclose information about deferred tax assets and liabilities related to Pillar Two income taxes. Based on the review of Pillar Two impact for the current year, no material amounts were identified to be accrued for the period ended 30 June 2026. The Group continues to monitor the impact of this legislation.

There were no movements in the Company's share capital and share premium during period ended 30 June 2026.

As of 30 June 2026, total number of voting rights in the Company amounted to 443,146,134 ordinary shares of nominal value US$ 0.03 each (31 December 2025: 443,146,134 ordinary shares), each carrying one vote, and additionally the Company held 123,408,853 shares in treasury as indicated in AIX register and such shares did not enjoy any voting or economic rights (31 December 2025: 123,408,853 shares).

The ordinary shares reflect 100% of the total issued share capital of the Company.

The calculation of the basic and diluted earnings per share is based on the following data:

Weighted average number of shares: Diluted earnings per share

Both basic and diluted earnings per share were calculated by dividing profit for the period attributable to equity holders of the parent by the weighted average number of outstanding common shares before/after dilution respectively. The calculation of the weighted average number of outstanding common shares after dilution is as follows:

There were no adjustments required to earnings for the purposes of calculating the diluted earnings per share in the current period (period ended 30 June 2025: nil).

There were no adjustments to weighted average number of shares for the purposes of calculating the diluted earnings per share in the current period (period ended 30 June 2025: none), as there are no outstanding Long-Term Incentive Plan (LTIP) awards as of the reporting date (30 June 2025: no dilutive potential ordinary shares).

The remaining LTIP tranche, granted in 2021 lapsed during first half 2025 and, accordingly, the related balance of US$ 4 million in the share-based payment reserve was transferred into retained earnings.

Metal in circuit increased due to temporary Kyzyl inventory accumulation in May-June 2026.

Write-downs of metal inventories to net realisable value

There were no write-downs or reversals to net realisable value of metal and other inventories during the periods ended 30 June 2026 and 2025.

No inventories held at net realisable value at 30 June 2026 and 31 December 2025.

Loans provided to third parties include a US$ 162 million loan extended to Bai Tau Minerals for three years at a market rate (US$ 164 million contractual amount less a US$ 2 million expected credit loss; 31 December 2025: US$ 128 million). Bai Tau Minerals holds the investment in JSC“Ulmus Besshoky”.

Receivables from provisional copper, gold and silver concentrate sales decreased to US$11 million as of 30 June 2026 (31 December 2025: US$ 61 million), primarily due to lower concentrate sales during the second quarter of 2026, for which revenue is expected to be received in the third quarter 2026.

Significant change in estimate in the six months ended 30 June 2026

In June 2026, the Group signed Amendment to Subsoil Use Contract (Kyzyl). The amendment changed the calculation of the annual socio-economic contribution from a fixed amount to 1% of total annual income (subject to a minimum of USD 2 million) starting from 2028.

The related remeasurement of the provision (net of the unwinding of the discount) has been capitalised to development costs.

The Group has a number of borrowing arrangements with various lenders. As of 30 June 2026, these borrowings consist of unsecured and secured loans and credit facilities, predominantly denominated in US Dollar.

The Group's non-current borrowings include borrowings amounting to US$ 150 million that contain covenants, which, if not met, would result in the borrowings becoming repayable on demand. These borrowings are otherwise repayable more than 12 months after the end of the reporting period. As at 30 June 2026, the Group has complied with all the covenants that were required to be met on or before 30 June 2026. The covenants that are required to be complied with after the end of the current reporting period do not affect the classification of the related borrowings as current or non-current at the end of the current reporting period. Therefore, all these borrowings remain classified as non-current liabilities.

Movements in borrowings are presented in Note 22 below.

The table below summarises maturities of borrowings:

Capital commitments

The Group's budgeted capital expenditure commitments as at 30 June 2026 amounted to US$ 411 million net of VAT (31 December 2025: US$ 158 million). The increase in capital commitments is due to the acceleration of construction works at Ertis POX, in accordance with the schedule.

Social commitments

In accordance with various memoranda with regional Akimats (local Kazakhstan government bodies), the Group participates in financing of certain social and infrastructure development project of the region. The total social expense commitment as at 30 June 2026 amounts to US$ 6 million, payable in the future periods.

Taxation

Kazakhstan tax, currency and customs legislation is subject to varying interpretations, and changes, which can occur frequently. Management's interpretation of such legislation as applied to the transactions and activities of the companies of the Group may be challenged by the relevant regional and federal authorities and as a result, significant additional taxes, penalties and interest may be assessed. Fiscal periods remain open to review by the authorities in respect of taxes for five calendar years preceding the year of review. Under certain circumstances reviews may cover longer periods.

Management has not identified any tax exposures in respect of contingent liabilities as of 30 June 2026 and 31 December 2025.

The following table provides an analysis of financial instruments that are measured subsequent to initial recognition at fair value, grouped into Levels 1 to 3 based on the degree to which the fair value is observable as follows:

Level 1 fair value measurements are those derived from quoted prices (unadjusted) in active markets for identical assets or liabilities;

Level 2 fair value measurements are those derived from inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly or indirectly; and

Level 3 fair value measurements are those derived from valuation techniques that include inputs for the asset or liability that are not based on observable market data (unobservable inputs).

At 30 June 2026 and 31 December 2025, the Group held the following financial instruments at fair value. During both reporting periods presented, there were no transfers between levels of fair value hierarchy.

Receivables from conditional share exchange

In October 2025, as part of the Final Exchange Offer, the Company entered into a conditional exchange offer buyback agreement to repurchase and exchange 11.1 million shares for AIX-listed ordinary shares on a one-for-one basis where the completion is subject to completion of the restricted share disposal, the cessation (or licensing) of applicable sanctions, and Euroclear receiving the buyback price from the trustee and distributing it to the direct participants.

The Group recognised a financial asset of USD 11 million, representing the reimbursement of the buyback price for such shares. The asset is classified and measured at fair value through profit or loss (FVTPL). The Group classified the receivable as non-current, as the conditions for completion are not expected to be fulfilled during the 12 months after the reporting date.

The receivable is classified within Level 3 of the fair value hierarchy. The fair value is estimated using a probability-weighted discounted cash flow technique. Key unobservable inputs include the probability of sanctions relief, the expected timing of the Euroclear distribution, and estimated trustee deductions. There were no transfers into or out of Level 3 during the six months ended 30 June 2026.

Equity investments designated at FVTOCI

In June 2025, the Group completed the acquisition of 10.68% interest in JSC“Ulmus Besshoky” (Besshoky) for total consideration of US$ 15 million. The acquisition was made through several consecutive deals with third parties. Besshoky is an exploration company, holding Besshoky project in Karaganda region, consisting of main exploration contracts and several exploration licenses for the adjacent areas. This investment in equity instruments is not held for trading. Instead, it was acquired for medium to long-term strategic purposes. Accordingly, the Group has elected to designate these investments in equity instruments as at FVTOCI as recognising short-term movements in the investment's fair value in profit or loss would not be consistent with the group's strategy of holding it for long-term purposes.

During the six months ended 30 June 2026 the Group recognised a fair value decrease of US$ 7 million on this investment in other comprehensive income (with a corresponding decrease in the fair value reserve within equity). As at 30 June 2026 the carrying amount of the investment was US$ 19 million (31 December 2025: US$ 26 million).

Borrowings

The estimated fair value of the Group's debt, calculated using the market interest rate available to the Group as at 30 June 2026 and 31 December 2025 did not differ from its carrying value.

Receivables from provisional copper, gold and silver concentrate sales

The fair value of receivables arising from copper, gold and silver concentrate sales contracts that contain provisional pricing mechanisms is determined using the appropriate quoted forward price from the exchange that is the principal active market for the particular metal. As such, these receivables are classified within Level 2 of the fair value hierarchy.

Related parties are considered to include shareholders, associates, joint ventures and entities under common ownership and control with the Group and members of key management personnel.

The Group had the following outstanding balances with related parties:

During the six months ended 30 June 2026 the Group advanced additional loans to related parties of US$ 6 million (six months ended 30 June 2025: nil). The loans are unsecured, interest-bearing and repayable in accordance with the contractual terms.

There were no other significant transactions with related parties during the six months ended 30 June 2026 or 30 June 2025.

Cash and cash equivalents

Changes in liabilities arising from financing activities

The table below details changes in the Group's liabilities arising from financing activities, including both cash and non-cash changes. Liabilities from financing activities are those for which cash flow were, or future cash flows will be, classified in the Group's consolidated cash flow statements as cash flows from financing activities.

In July 2026, the Group secured US$ 600 million of committed financing for the construction of the Ertis POX project. The package comprises:

• a US$ 300 million 10-year loan from the European Bank for Reconstruction and Development (EBRD); and
• a US$ 300 million syndicated facility provided equally by ING (Coordinating Mandated Lead Arranger), Société Générale and Abu Dhabi Commercial Bank, with an initial tenor of five years (extendable to seven years) and an accordion option of up to an additional US$ 300 million.

The facilities have a 36-month grace period, with repayments scheduled to commence in 2029 following the completion of construction.

In September 2026, the Group signed a US$100 million seven-year facility with KfW IPEX-Bank to finance the Ertis POX project.

In July 2026, subsequent to the reporting date, the Group, through Solidcore Middle East SPC, entered into an earn-in agreement and a shareholders' agreement with Minerals Development Oman SAOC and Minerals Development Oman First LLC in relation to the Khabiyat copper-gold project in Oman. The project is held through Majan Base Metals LLC.

Under the agreements, the Group will acquire an initial 20% interest in Majan Base Metals LLC. Following satisfaction or waiver of specified conditions, the Group will pay US$ 6.9 million to Minerals Development Oman as consideration for the initial 20% interest, of which US$ 6.4 million will be contributed by Minerals Development Oman to Majan Base Metals LLC as part of the US$ 8.0 million Stage 1 exploration funding. The Group will contribute the remaining US$ 1.6 million. As at the date of approval of these condensed consolidated interim financial statements, those conditions had not been satisfied, and neither the share consideration nor the Stage 1 contribution had been paid.

On completion of Stage 1, the Group is required to pay a further US$ 1.5 million to Minerals Development Oman. Subject to completion of the applicable exploration, funding, share-purchase and other contractual conditions, the Group may elect to increase its interest to 45% (Stage 2) and subsequently to 60% (Stage 3).

If the Group exercises these rights, at Stage 2 it will pay a further US$ 11.0 million to Minerals Development Oman First LLC and contribute a further US$ 9.0 million to Majan Base Metals LLC. At Stage 3, the Group will pay an election payment of US$ 1.5 million to Minerals Development Oman First LLC, together with the purchase price for the additional shares, which is also payable to Minerals Development Oman First LLC. The Stage 3 purchase price is formula-based and could not be estimated reliably as at the date these condensed consolidated interim financial statements were approved.

Specified decisions concerning the activities that significantly affect the returns of Majan Base Metals LLC, including approval of the work programme and budget, material technical studies, licences and the development concept, require the agreement of both shareholders. Following completion of the initial acquisition and effectiveness of the relevant governance provisions, the Group is assessing the date from which it obtained, or will obtain, joint control. From that date, the investment will be classified as a joint venture under IFRS 11 Joint Arrangements and accounted for using the equity method.

The transaction is a non-adjusting event after the reporting period. Accordingly, no investment in Majan Base Metals LLC has been recognised in the interim condensed consolidated statement of financial position as at 30 June 2026.

ALTERNATIVE PERFORMANCE MEASURES

Introduction

The financial performance reported by the Company contains certain Alternative Performance Measures (APMs), disclosed to complement measures that are defined or specified under International Financial Reporting Standards (IFRS). APMs should be considered in addition to, and not as a substitute for, measures of financial performance, financial position or cash flows reported in accordance with IFRS.

The Company believes that these measures, together with measures determined in accordance with IFRS, provide the readers with valuable information and an improved understanding of the underlying performance of the business.

APMs are not uniformly defined by all companies, including those within the Group's industry. Therefore, the APMs used by the Company may not be comparable to similar measures and disclosures made by other companies.

Purpose

APMs used by the Company represent financial KPIs for clarifying the financial performance of the Company and measuring it against strategic objectives, given the following background:

• Widely used by the investor and analyst community in the mining sector and, together with IFRS measures, provide a holistic view of the Company;
• Applied by investors to assess earnings quality, facilitate period to period trend analysis and forecasting of future earnings, and understand performance through eyes of management;
• Highlight key value drivers within the business that may not be obvious in the financial statements;
• Ensure comparability of information between reporting periods and operating segments by adjusting for uncontrollable or one-off factors which impact upon IFRS measures;
• Used internally by management to assess the financial performance of the Company and its operating segments; and
• Certain APMs are used in setting directors' and management's remuneration (i.e., total cash costs adjusted for gold price related expenses).
