On April 2, 2024, Nexa BR concluded a debenture issuance amounting to BRL 650,000 (approximately USD 130,099) with an annual interest rate of CDI plus 1.50% p.a., for a 6-year term with semi-annual payments.

2 Information by business segment

Segment performance is assessed based on Adjusted EBITDA, since net financial results, comprising financial income and expenses and other financial items, and income tax are managed at the corporate level and are not allocated to operating segments.

The Company defines Adjusted EBITDA as follows: net income (loss) for the year/period, adjusted by (i) share in the results of associates, depreciation and amortization, net financial results and income tax; (ii) addition of cash dividends received from associates; (iii) non-cash events and non-cash gains or losses that do not specifically reflect its operational performance for the specific period, such as: gain (loss) on sale of investments; impairment and impairment reversals; gain (loss) on sale of long-lived assets; write-offs of long-lived assets; remeasurement in estimates of asset retirement obligations; and other restoration obligations; and (iii) pre-operating and ramp-up expenses incurred during the commissioning and ramp-up phases of greenfield projects. In addition, management may adjust the effect of certain types of transactions that in its judgment are (i) events that are non-recurring, unusual or infrequent, and (ii) other specific events that, by their nature and scope, do not reflect Nexa’s operational performance for the year/period.

The adjusted EBITDA is derived from internal information prepared in accordance with the International Financial Reporting Standards (“IFRS Accounting Standards”) and based on accounting measurements and management reclassifications between income statement lines items, which are reconciled to the consolidated financial statements in the column “Adjustments”, as shown in the tables below. These adjustments include reclassifications of certain overhead costs and revenues from “Other income and expenses, net” to “Net Revenues, Cost of salesand/or Selling”, “General and administrative expenses”.

The Company uses customary market terms for intersegment sales. The Company’s corporate headquarters expenses are allocated to the operating segments to the extent they are included in the measures of performance used by the Chief operating decision maker (CODM).

(i) This amount represents the change in the fair value of the offtake agreement described in note 10, which is being measured at Fair value through profit or loss (“FVTPL”). This change in the fair value is a non-cash item and has not been considered in the Company’s Adjusted EBITDA calculation.

(ii) Excludes the impact of commissioning, pre-operating, and ramp-up expenses of greenfield projects. For the nine-month period ended on September 30, 2024, this corresponds to the effects of idle capacity costs of Aripuanã of USD 25,499 and excludes the net reversal of the net realizable value provision of Aripuanã’s inventory of USD 341 (excluding the depreciation portion). Aripuanã completed its ramp-up phase at the end of the second quarter of 2024.

(iii) The fair value adjustment of the energy surplus resulting from electric energy purchase contracts of NEXA’s subsidiary, Pollarix, as disclosed in note 10(d). This change in the fair value is a non-cash item and has not been considered in the Company’s Adjusted EBITDA calculation.

(iv) Change of provision related to estimated costs of anticipated additional obligations in relation to certain inactive industrial waste containment structures in Brazil that have been closed for more than 20 years and that do not contain mining tailings, water or liquid waste as disclosed in note 16 (a). As such, they have not contributed to Nexa’s operational performance.

(v) Refers to the effects of restructuring obligations, and the gain or loss related to the divestment of assets held for sale, as mentioned in note 6. These amounts are excluded from the Adjusted EBITDA calculation, as they do not specifically reflect Nexa’s operational performance.

(vi) Refers to dividends received from associate company Campos Novos Energia S.A – Enercan, an entity focused on energy generation. As the purpose of Nexa’s investment in Enercan is to secure long-term energy supply for its operations in Brazil, the chief operating decision maker (CODM) considers Nexa’s energy costs for a given period together with dividends received from Enercan during such period. Nexa recognized its share of the assets, liabilities, revenues and expenses for its interest in Enercan until November 2022, when it ceased to be a jointly controlled operation. Beginning in 2024, Nexa includes these dividends in its Adjusted EBITDA, as the CODM considers them jointly with Nexa’s energy costs. Numbers for the nine months ended on September 30, 2023, do not include dividends received from Enercan because it referred to the period during which Enercan was recognized as a jointly controlled operation in Nexa’s results. Without the adjustment, the Adjusted EBITDA (i) for the three months ended on September 30, 2024, would have been USD 3,920 and USD 2,555 for the mining and smelting segments, respectively, and (ii) for the nine months ended September 30, 2024, would have been USD 5,043 and USD 11,115 for mining and smelting segments, respectively.

3 Basis of preparation of the condensed consolidated interim financial statements

These condensed consolidated interim financial statements as at and for the three and nine-month periods ended on September 30, 2024, have been prepared in accordance with the International Accounting Standard 34 Interim Financial Reporting (“IAS 34”) using the accounting principles consistent with the IFRS Accounting Standards and Interpretations, as issued by the International Accounting Standards Board (“IASB”).

The Company made a voluntary election to present, as supplementary information, the condensed consolidated interim statement of cash flows for the three-month periods ended on September 30, 2024, and 2023. The Company is also presenting a condensed consolidated interim statement of changes in shareholders’ equity for the three-month period ended on September 30, 2024, and 2023 in accordance with SEC Final Rule Release No. 33-10532, Disclosure Update and Simplification.

These condensed consolidated interim financial statements do not include all disclosures required by the IFRS Accounting Standards for annual consolidated financial statements and accordingly, should be read in conjunction with the Company’s audited consolidated financial statements for the year ended on December 31, 2023, prepared in accordance with the IFRS Accounting Standards as issued by the IASB.

These condensed consolidated interim financial statements have been prepared on the basis of, and using the accounting policies, methods of computation and presentation consistent with those applied and disclosed in the Company’s audited consolidated financial statements for the year ended on December 31, 2023.

The Company has not early adopted any new standard, interpretation or amendment that has been issued but is not yet effective.

The preparation of these condensed consolidated interim financial statements in accordance with IAS 34 requires the use of certain critical accounting estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses for the period end. Such estimates and assumptions mainly affect the carrying amounts of the Company’s goodwill, contractual obligations, non-current assets, indefinite-lived intangible assets, inventory, deferred income taxes, and the allowance for doubtful accounts. These critical accounting estimates and assumptions represent approximations that are uncertain and changes in those estimates and assumptions could materially impact the Company’s condensed consolidated interim financial statements.

The critical judgments, estimates and assumptions in the application of accounting principles during the three and nine-month periods ended on September 30, 2024, are the same as those disclosed in the Company’s audited consolidated financial statements for the year ended on December 31, 2023.

These condensed consolidated interim financial statements for the three and nine-month periods ended on September 30, 2024, were approved on October 31, 2024, to be issued in accordance with a resolution of the Board of Directors.

| --- | --- | | 3.1 | Revision of the previously issued consolidated financial statements | | --- | --- |

During the three-month period ended on September 30,2024, the Company identified a misstatement in the previously issued consolidated financial statements for the year 2023 and 2022, and in the previously issued condensed consolidated interim financial statements for periods ended March 31, June 30 and September 30, 2023, and 2024. As a result, the comparative information for the year ended December 31, 2023, and for the period ended September 30, 2023, were revised to reflect the adjustments.

Right-of-use assets and leaseliabilities

The Company identified an error in the recognition of contracts containing lease arrangements. This error resulted in the non-recognition of right-of-use assets and lease liabilities, as well as the misstatement of costs and expenses that should have impacted the Company’s results through the amortization of right-of-use assets and interest expense on the lease liabilities, instead of being recorded as costs and operational expenses related to third-party services. This adjustment led to the recognition of right-of-use assets of USD 63,590 and lease liabilities of USD 68,187 as of December 31, 2023, affecting the Company’s income statements, as shown in the charts below. The difference between the incorrectly recognized expenses in previous periods and the revised amounts as per the adjustments in the amortization of the right-of-use assets and the lease liability interest, was recorded to retained earnings (or cumulative deficit) in the statement of changes in shareholders’ equity, as of January 1st, 2023.

The Company’s management performed quantitative and qualitative analysis and concluded that those adjustments were not material to the previously issued financial statements as of and for the years ended December 31, 2023, and 2022 and condensed consolidated interim financial statements for the nine and three-months ended on September 30, 2023. Nevertheless, in order to keep consistency among the figures presented, the comparative information for the year ended December 31, 2023, and for the quarter ended September 30, 2023, were revised, and disclosure of the revised amounts on other prior periods will be reflected in future filings containing the applicable period.

3.1.1 Consolidated financial impacts

The following tables present the adjustments and the revised figures to the previously issued consolidated financial statements.

(i) Billing from products increased in the three-month period ended on September 30, 2024, compared to the same period in 2023 mainly due to higher zinc and copper metal prices, which was partially offset by slightly lower mining and smelting sales volumes. The increase in the nine-month period ended on September 30, 2024, is mainly because of the higher volume sold in the mining segment.

Additionally, in September 2024, Nexa recognized a reduction of USD 21,084 (September 30, 2023: USD 2,323) as an annual remeasurement adjustment to its silver stream revenue previously recognized, considering the higher long-term prices and the updated mining plan for its Cerro Lindo Mining Unit. According to the Company´s silver streaming accounting policy, prices fluctuations and changes in the life of mine (“LOM) resulting from updates to mining plans are variable considerations. Therefore, revenue recognized under the streaming agreement should be adjusted to reflect these updated variables.

(i) In the nine-month period ended on September 30, 2024, the Company recognized USD 3,661 in Cost of sales related to idle capacity cost in El Porvenir due to the suspension of the mine for ten days (USD 9,256 as of September 30, 2023) and USD 34,591 including depreciation of USD 9,092 (USD 59,061 including depreciation of USD 17,272 as of September 30, 2023) related to the idleness of the Aripuanã mine and plant capacity incurred during the ramp-up phase.

(ii) Raw materials and consumables used decreased in the nine-month period ended on September 30, 2024, due to a decrease in the volume sold in the Company’s smelting segment.

(i) In December 2021, the Company adhered to a Brazilian Law which states that government grants of the “Imposto sobre circulação de mercadorias e serviços” (“ICMS”) tax incentives are considered investment subsidies and should be excluded from taxable income for the purpose of calculating the Corporate Income Tax (“IRPJ”) and the Social Contribution on Net Income tax (“CSLL”).

| --- | --- |

On December 29, 2023, a new law No. 14,789/2023 was published, revoking the treatment for purposes of IRPJ and CSLL of subsidies for investments by creating a new tax credit mechanism. The new rule also provides a limited concept of subsidy of investments only covering VAT benefits aimed to implement or expand an economic enterprise.

This new regulation came into effect in 2024, and the Company assessed that, for now, it should not continue to exclude the ICMS tax incentives from the IRPJ/CSLL basis.

(ii) The change in the three and nine-month period ended September 30, 2024, mainly due to the update of the remeasurement discount rate and an addition of asset retirement obligation related to non-operational structures in the Peruvian subsidiary.

(iii) Refers to estimated obligations related to restructuring expenses, regarding the Morro Agudo sale agreement mentioned in note 1 (b). The sales and restructuring plan were disclosed to its employees and other stakeholders. This amount was accounted for as “Other Current Liabilities”.

(i) The amounts for the nine-month period ended in 2024, are mainly due to exchange variation on the outstanding USD accounts receivables and accounts payables of Nexa BR with Nexa, intercompany loan of Nexa BR with its related parties, for which the exchange variation is not eliminated in the consolidation process, and loans in foreign currency. These transactions were impacted by the volatility of the Brazilian Real (“BRL”), which depreciated against the USD during 2024 (appreciated during 2023).

(i) During the period ended September 30, 2024, the Company performed an assessment of the group’s potential exposure to Pillar Two income taxes based on the OECD transitional safe harbor rules. This assessment was performed based on the interim financial information of the constituent entities in the group. As a result of the assessment performed, the jurisdictions where the Company operates qualify for at least one of the transitional safe harbor rules, and management is not currently aware of any circumstances under which this might change. Therefore, the Company has not identified any potential exposure to Pillar Two top-up tax.

In addition, as from January 1, 2024, Law 14.596/2023 came into force introducing new transfer pricing rules in Brazil. These rules aim to align with the international standards established by the OECD, according to the arm’s length principle, which stipulates that the terms and conditions of a controlled transaction should be consistent with those that would be established between third parties in comparable transactions. The new rules are expected to affect only transactions involving Nexa BR, as transactions involving Nexa Peru and Nexa Resources already comply with international standards established by the OECD.

The Company, with the support of its technical advisors, is in the process of assessing how the new rules will impact its related party transactions, including commercial, services, intangible, and finance operations. Therefore, it is not yet possible to determine the potential impact of the new transfer pricing rules on transactions between its related parties.

(ii) The projection of the effective tax rate is carried out to approximately reflect in the interim financial statements the expected tax burden on the company’s profit by the end of the period. This considers a detailed analysis of the potential future tax factors, anticipated changes in tax legislation, and possible variations between accounting profit and the tax base. This estimate is made in accordance with IAS 34, aiming to provide a more accurate view of the impact of taxes on the company's future financial performance.

(c) Summary of uncertain tax positions on income tax
--- ---

There are discussions and ongoing disputes with tax authorities related to uncertain tax positions adopted by the Company in the calculation of its income tax, and for which management, supported by its legal counsel, has concluded that it is more-likely-than-not that its positions will be sustained upon examination. In such cases, tax provisions are not recognized.

As of September 30, 2024, the main legal proceedings are related to: (i) the interpretation of the application of Cerro Lindo’s stability agreement; and (ii) litigation of transfer pricing adjustments over transactions made with related parties. The estimated amount of these contingent liabilities on September 30, 2024, is USD 480,640, which increased compared to that estimated on December 31, 2023, of USD 478,329, mainly due to: (i) the Cajamarquilla’ s new tax assessment of transfer pricing issues and the deductibility of certain expenses in the 2017 corporate income tax calculation, partially offset by the deductibility of some expenses in the 2016 corporate income tax calculation; and, (ii) a reduction in Cerro Lindo´s income tax advance payments for the years 2015, 2016 and 2017, as the debt is no longer due considering the expiration of the statute of limitations, which was partially offset by an increase in deductible expenses.

Regarding Cerro Lindo’s stability agreement, the Peruvian tax authority (hereinafter SUNAT) issued unfavorable decisions against the Company for the years 2014, 2015, 2016 and 2017, arguing that the income tax rate granted by the stability agreement applies only to the income generated from 5,000 tons per day of its production, and not from its entire production capacity expanded over time. The Company has filed appeals against these decisions. SUNAT is currently auditing 2018 and 2019, while the years 2020 and 2021 (when the term of the stability agreement expired) remain open. Although SUNAT maintains its position disregarding the stabilized rate and taxing the Company’s total income at the statutory income tax rate for these years, the Company continues to maintain its position in relation to the applicability of the Cerro Lindo stability agreement. The Company’s Management, supported by the opinion of its external advisors, continues to conclude that there are legal grounds to obtain a favorable outcome in these matters related to the tax stability rate discussion and believes that it is more-likely-than-not that its positions will be sustained upon examination by the legal authorities. However, the Company may have to pay the disputed amounts under discussion to SUNAT to continue the legal process either at the judicial or international arbitration levels. Such payments may be made in several installments provided that a guarantee is placed before the courts and may impact the Company’s results and cash flows.

(i) On January 25, 2022, the Company signed an offtake agreement with an Offtaker to sell 100% of the copper concentrate produced by Aripuanã for 5 years. In July 2023, the contract was amended, including provisions for additional deliveries and time extension until Nexa fulfills the delivery of the originally agreed-upon volumes. The transaction price is the lower of current market prices or a price cap, from the most updated schedule of copper concentrates deliveries. In June 2023, the Company began deliveries of copper concentrates concerning the offtake agreement mentioned above.

(ii) During 2024, there were sales with the copper price higher than the price cap, therefore resulting in the reduction of the financial instrument liability for these sales, and the revenue recognition according to its fair values.

(b) Loans and financing transactions during the nine-month period ended September 30, 2024

In March 2024, Nexa Recursos Minerais (Nexa BR) entered into a Note agreement in the total principal amount of EUR 27,917 (approximately USD 30,244) at an annual gross interest rate of 5.6% p.a., maturing in June 2024. Additionally, a global derivative contract was established to swap the currency fluctuation of the euro to hedge this loan operation, with a notional value of EUR 27,917, maturing on June 3, 2024, and a coverage percentage of 100% at a cost of CDI (Interbank Certificate of Deposit) + 0.90%. Both contracts were classified as fair value through profit or loss. On June 3, 2024, the Note Agreement was settled in cash, with a total payment of USD 30,683 (EUR 28,234), comprised of USD 30,244 of principal and USD 360 of interest expenses, including USD 79 of exchange variation.

On April 2, 2024, Nexa BR concluded a debenture issuance in the amount of BRL 650,000 (approximately USD 130,099), with an annual interest rate of CDI plus 1.50% p.a., for a 6-year term with semi-annual payments. The debenture was issued under the "Private Instrument of Indenture of the 1st (First) Issuance of Simple Debentures” and submitted for registration with the Brazilian Securities Commission ("CVM") under the automatic distribution registration procedure, pursuant to CVM Resolution 160. The Debenture is characterized as “ESG-linked debentures”, as the Company will have an option of redemption or amortization premium in case it meets certain agreed upon ESG goals.

Early redemption of the full notes or anticipated amortization options will be available from April 1, 2026, subject to an annually decreasing payment of a premium. This premium could be reduced if Nexa meets the annual 2025-2028 greenhouse gas emission reduction targets outlined in Nexa’s ESG goals framework.

On April 9, 2024, the Company concluded a bond offering in the amount of USD 600,000, for a period of 10 years, at an interest rate of 6.75% per year, and used the proceeds to repurchase part of its 2027 and 2028 notes in a concurrent tender offer.

On June 12, 2024, Nexa BR drew from BNDES (Brazilian national bank for economic and social development) an ESG credit line linked to the continuous improvement of the Company's environmental and social indicators, in the amount of BRL 200,000 (approximately USD 40,030), maturing in March 2032. The amortization will occur in 72 consecutive installments after a 2-year grace period provided in the contract, at an annual cost of IPCA plus 5.41% p.a., and a spread rate of 1.84%. After the 2-year grace period, the spread rate of 1.84% can be reduced to 1.44% if ESG goals are met, otherwise, the rate is increased to 2.84%.

(ii) The change observed for the period ended September 30, 2024, was mainly due to an “out of period” adjustment of USD 13,416 in the asset retirement obligation related to old and non-operational structures in the Peruvian subsidiaries, which were not identified in previous years and therefore were not recognized by the Company. Additionally, there were changes in the timing of expected disbursements on decommissioning obligations in certain operations, in accordance with updates in their dam obligations, asset retirement and environmental obligations studies, along with an increase in the discount rate, as described above. As a result, as of September 30, 2024, the Company’s asset retirement obligations for operational assets decreased by USD 1,638 (September 30, 2023: decrease of USD 1,457) as shown in note 12. The Company also recognized an expense of USD 23,840 (September 30, 2023: gain of USD 1,205), as shown in note 6.

(iii) The Company has been conducting engineering studies to confirm the construction method of some inactive industrial waste containment structures that have been closed for more than 20 years. None of them contain mining tailings, water or liquid waste. Based on the results of the conceptual engineering studies, the Company has reserved amounts related to estimated costs of anticipated additional restoration obligations in relation to these closed facilities.

17 Long-term commitments
(a) Projects evaluation
--- ---

As part of NEXA’s activities for the execution of certain greenfield projects, on February 8, 2024, the Peruvian Government accepted the company's request to postpone the deadline for the Accreditable Investment Commitment under the Magistral Transfer Contract from September 2024 to August 2028. As of September 30, 2024, the unexecuted Accreditable Investment Commitment was USD 323,000, and if not completed by August 2028, the potential penalty exposure could be USD 97,029.

In December 2021, Nexa submitted a request for the Modification of the Environmental Impact Assessment (MEIA) for the Magistral Project to the National Environmental Certification Agency (SENACE), through the applicable legal process. During the approval process, the Peruvian Water Authority (ANA) and the Protected Natural Areas Service - (SERNANP) raised unfavorable observations. On May 24, 2024, SENACE formally rejected the MEIA.

Nexa is currently addressing this situation with the relevant authorities and expects to receive a response in the coming months.


(b) Environmental Guarantee for Dams

On December 30, 2023, the Decree 48,747 of 2023 of Minas Gerais State was published, which regulates the need for an environmental guarantee, provided for in Law 23,291 of February 25, 2019, the State Policy for Dam Safety, to guarantee environmental recovery in the event of an accident or deactivation of the dams. According to the Decree, the environmental guarantee is applicable to all dams that present the characteristics established by the law. The Company estimates a guarantee need of approximately USD 21,293 (BRL 116,008) for all structures in the state of Minas Gerais. This amount was calculated based on a methodology specified by the Decree itself, which takes into account the reservoir area, a cost factor related to the decommissioning of dams, considerations about the risk classification of the dam, and inflation for the period.

During the second quarter, the Decree was amended, among others, to modify the deadline for the mining companies to submit to the environmental agency of the state of Minas Gerais a proposal of which type(s) of guarantee method(s) it will offer. In compliance with the established deadline, the Company confirmed in September that it will utilize a bank guarantee. The Company also expects to contract 50% of the chosen guarantee by December 31, 2024, 25% by December 31, 2025, and 25% by the end of 2026, according to the schedule established by the Decree.

| --- | --- | | 18 | Impairment of long-lived assets | | --- | --- |

Impairment test analysis

Throughout 2024, the Company, at each reporting date, assessed whether there were indicators that the carrying amount of an asset, goodwill, or cash generation unit (CGU) might not be recoverable, or if a previously recorded impairment needed to be reversed.

Goodwill assessment

As of September 30, 2024, Nexa conducted its annual impairment test for the CGUs to which goodwill has been previously allocated including Mining Peru group of CGUs (Composed of Cerro Pasco and Cerro Lindo CGUs), Cajamarquilla and Juiz de Fora in accordance with the assumptions and projections outlined in the Company’s strategic planning process. As a result, no impairment was identified.

Peruvian CGU

The Company identified indicators of reversal, primarily driven by the increase of short-term and long-term metal prices. As a result, an impairment reversal for USD 22,206 was recognized at the CGU Cerro Pasco.

Magistral Project assessment

Because of the rejection of the Company’s MEIA described in Note 17 (a), in June 2024, the Magistral Project was tested for impairment resulting in a loss of USD 58,435, recognized in profit or loss. This impairment was determined using the fair value less cost of disposal (FVLCD) recoverable amount, based on market past transaction multiples (amount paid per ton of minerals for projects in similar stages).

Pukaqaqa Project assessment

In the second quarter of 2024, Nexa´s management analyzed alternatives for the sale of Pukaqaqa mining project, part of Nexa Peru´s portfolio and in the third quarter of 2024 the Company signed a purchase and sale agreement to sell Compañía Minera Cerro Colorado S.A.C. owner of the greenfield Pukaqaqa Project. This triggered an impairment assessment as the project’s assets had been fully impaired based on the 2022 impairment evaluation.

The Company considered the most recent negotiation with the third-party to calculate the fair value less cost of disposal, considering the sales price and other obligations defined in the offer. As of September 30, 2024, the impairment assessment resulted in the recognition of an impairment reversal of USD 3,978.

Compañía Minera Shalipayco S.A.C.

In June 2024, Compañía Minera Shalipayco S.A.C. (the joint operation between Nexa and PAS) decided not to renew the rights for the mining concessions of the Shalipayco project. As a result of this decision, it was agreed to commence the dissolution process of said Company after unsuccessful attempts to find a potential buyer. This investment project in Nexa Peru was impaired in 2022 as part of Nexa’s portfolio review. Consequently, no further material adjustment has been recognized in the nine-month period ended on September 30, 2024.

Morro Agudo CGU

In the first quarter of 2024, Nexa received a binding sale offer from a third party for Morro Agudo CGU. The sale transaction was completed on July 1, 2024 (as further described in Note 1 (b)), and the Company recorded an impairment reversal of USD 10,291 for the nine-month period ended on September 30, 2024.

Aripuanã CGU

The Company tested Aripuanã CGU after identifying impairment indicators related to (i) a devaluation of the exchange rate of BRL/USD; and (ii) an increase in operational costs for Aripuanã. No impairment was identified after the impairment assessment.

Impairment test summary

In summary, for the nine-month period ended September 30, Nexa recognized the following impairment loss/reversal:

Impairment (losses) reversals 2024 2023
Magistral<br> Project (58,435) -
Cerro<br> Pasco CGU 22,206 -
Morro<br> Agudo 10,291 (57,702)
Pukaqaqa<br> Project 3,978 -
Others<br> individual assets (3,439) (1,395)
Total (25,399) (59,097)
(a) Key assumptions used in impairment test
--- ---

The recoverable amounts for each CGU were determined based on the FVLCD method, which were higher than those determined based on the VIU method.

The Company identified long-term metal prices, discount rate, exchange rate considering Brazilian real (BRL), and LOM as key assumptions in determining the recoverable amounts, due to the material impact such assumptions may have on the recoverable value. Part of these assumptions are summarized below:

2024 2023
Long-term<br> zinc price (USD/t) 2,930 2,800
Discount<br> rate (Peru) 7.08% 7.22%
Discount<br> rate (Brazil) 7.64% 8.02%
Exchange<br> rate (BRL x USD) 5.66 4.84
Brownfield<br> projects - LOM (Years) From<br> 3 to 25 From<br> 4 to 21

(b) Impairment reversal – Cerro Pasco CGU

As mentioned above, the impairment reversal was identified at the CGU level, not being directly related to a single asset. Then, the gain was allocated on a pro rata basis to the following assets:

**** Carrying amount prior to impairment reversal Impairment reversal Carrying amount after impairment reversal
Property, plant and equipment 223,788 12,400 236,188
Intangible assets 176,967 9,806 186,773
Other net liabilities (114,152) - (114,152)
286,603 22,206 308,809

The Company performed a stress test on the key assumptions used for the calculation of the recoverable amount of the CGU Cerro Pasco. A decrease of 5% in the long-term LME zinc price to USD 2,784 per ton compared to management´s estimation as of September 30, 2024, would have resulted in an impairment loss of USD 39,292 (or an impairment loss addition of USD 61,498). Also, an increase of 5% in the discount rate compared to management´s estimation, would have resulted in an impairment reversal of USD 14,932 (or a decrease in the impairment reversal of USD 7,274).

| --- | --- | | (c) | Sensitivity analysis – Tested CGUs and Goodwill | | --- | --- |

The Company estimated the amount by which the value assigned to the key assumptions must change for the assessed CGU recoverable amount, which was not impaired, to be equal to it carrying amount:

CGU Excess over recoverable amount Decrease<br> in Long term Zinc (/t) Increase in WACC Appreciation<br> of BRL over
Change Price Change Rate Change Price
Juiz<br> de fora 146,341 (23.33%) 2,246 71.13% 13.08% (13.00%) 4.92

Aripuanã 305,093 (15.43%) 2,478 56.34% 11.95% (13.88%) 4.87

All values are in US Dollars.

19 Events after the reporting period
