Main events for the three-months ended on March 31, 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 are classified as fair value through profit or loss.

On March 19, 2024, Nexa BR announced the suspension of its mining operations at the Morro Agudo Complex in the state of Minas Gerais in Brazil which will be effective from May 1, 2024. Subsequently, on April 5, 2024, Nexa BR signed a sale and purchase agreement to sell the Morro Agudo and Ambrosia mines (Morro Agudo CGU, classified within the mining segment operation). Additionally, the Company started a structured process to sell its non-operational Peruvian subsidiary, Minera Pampa Cobre S.A.C (owner of the asset Chapi mine). For further impact and details, refer to notes 6 and 12.

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) 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 dams obligations; and (iii) pre-operating and ramp-up expenses incurred during the com/missioning and ramp-up

 phases of greenfield projects. In addition, management may adjust the effect of certain types of transactions that in its judgments 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 sales and/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).

The presentation of segments results and reconciliation to income before income tax in the consolidated income statement is as follows:

(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 three months ended on March 31, 2024, corresponds to the effects of idle capacity costs of the Aripuanã of USD 14,160 and excludes the net reversal of the net realizable value provision of Aripuanã’s inventory of USD 341 (excluding the depreciation portion).

(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 adjustment to EBITDA excludes the remeasurement effects of energy contracts without cash impact for the specific period.

(iv) Remeasurement 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 effects of obligations of restructuring and divestment related to assets held for sale as mentioned in notes 1 (b) and 6 which are excluded from EBITDA considering that these amounts do not specifically reflect Nexa’s operational performance and business purpose.

These condensed consolidated interim financial statements as at and for the three months ended on March 31, 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 March 31, 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 March 31, 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 months ended on March 31, 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 months ended on March 31, 2024 were approved on April 30, 2024 to be issued in accordance with a resolution of the Board of Directors.

(i) Gross billing decreased in the three-month ended on March 31, 2024, compared to the same period in 2023 mainly due to lower zinc metal prices and lower volume sold. The decrease in volume was impacted by lower production in the Company´s smelting segment partially offset by higher production in the mines.

(i) During the first quarter of 2024, the Company recognized USD 1,599 in Cost of sales related to idle capacity cost in El Porvenir due to the suspension of the mine for some days (USD 6,191 as of March 31, 2023) and USD 19,295 including depreciation of USD 5,135 (USD 18,226 including depreciation of USD 5,714 as of March 31, 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 three-month period ended on March 31, 2024, because of lower volumes sold and a decrease in the price of zinc concentrates acquired from third parties and used in the Company’s smelting segment.

(iii) Nexa revised the comparative period as of March 31, 2023, which involves a reclassification of USD 9,365 from other expenses to third-party services. This adjustment addresses a misclassification identified within these accounts. Such adjustment does not affect the total amount of selling, general, and administrative expenses.

(i) In December 2021, the Company adhered to a Brazilian Law that 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) Refer to estimated obligations related to restructuring expenses. The plan was disclosed to its employees and other stakeholders, regarding the sales agreement and assets held for sale mentioned in notes 1 (b) and 12. This amount was accounted for as “Other Current Liabilities”.

(i) The amounts for the three months ended on 2024, are mainly due to exchange variation on the outstanding USD accounts receivable and accounts payables of Nexa BR with Nexa and exchange variation related to the intercompany loan of Nexa BR with its related parties which is not eliminated in the consolidation process. The 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 March 31, 2024, the Company has 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 a potential exposure to Pillar Two top-up tax.

(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 March 31, 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 March 31, 2024, is USD 501,242 which increased compared to that estimated on December 31, 2023, of USD 478,329, mainly due to a Cajamarquilla’ s new tax assessment of transfer pricing issues and the deductibility of some expenses in the corporate income tax calculation for the year 2017.

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 stability 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, which means 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 in favor to SUNAT to continue the legal process either in 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.

(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, and a possible contract extension is defined in the case of not delivering the scheduled volumes along the contract period, which the transaction price is the lower of current market prices or a price cap. In June 2023, the Company began with the deliveries of copper concentrates concerning the offtake agreement mentioned above.

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

In connection with operational optimization and assessment of strategic alternatives related to the Morro Agudo CGU (classified within the mining segment operation), on April 5, 2024, Nexa signed a sale and purchase agreement, to sell Morro Agudo and Ambrosia mines (Morro Agudo CGU) without any greenfield project, for a total purchase price of BRL 80,000 (approximately USD 16,012), plus a price adjustment regarding inventories of limestones that will comprise the assets sold.

The acquisition includes surface and mining rights, property, plant and equipment, and inventory related to the Morro Agudo CGU. Additionally, the buyer will be responsible for executing the future mine closure, which includes decommissioning all tailing storage facilities, and implementing an environmental remediation plan, if applicable. The closing of this transaction is expected to occur within the next quarter following the fulfilment of customary closing conditions, including a corporate restructuring of the assets comprising the Morro Agudo CGU.

Considering that the entire long-lived assets related to Morro Agudo CGU were impaired at December 31, 2023, Nexa updated its impairment test based on the consideration to be received and recognized the impairment reversal in the amount of USD 16,216 (refer to note 18 for further information on the long-lived assets impairment test) at March 31, 2024.

Additionally, the Company has initiated a structured process to sell a non-operational Peruvian subsidiary, Minera Pampa Cobre S.A.C (owner of the asset Chapi mine). The sale is expected to be finalized within a year.

As a result, the fair value of the assets and liabilities expected to be transferred in the transaction (disposal group) are presented as held for sale in the balance sheet on these condensed consolidated interim financial statements.

(i)The negative balances refer to related funding costs (fee) amortization.

In March 2024, the Company renegotiated a term loan with a principal amount of USD 90,000, maturing in October 2024, and with a cost based on the three-month term SOFR (“Secured Overnight Financing Rate”) plus 1.80% basis points (“bps”). The renegotiated debt with the same counterparty has a maturity of February 2029 and a cost of three-month term SOFR plus 2.40% bps. This transaction has been accounted for as debt modification, and a gain of USD 3,142 has been recognized in finance income.

The Company, through one of its subsidiaries, entered into a new credit line agreement of R$ 200,000 million, or approximately USD 40,030, with the Brazilian Economic and Social Bank (“BNDES”). This agreement, part of the "BNDES ESG Credit" program, aims to support the implementation of sustainable practices and is directly linked to the continuous improvement of the Company's environmental and social indicators.

The disbursement will depend on BNDES´ analysis of all Company documentation related to the operation, which the Company expects will occur over the year. After the disbursement, the loan will mature in 72 consecutive installments, with an annual interest rate of IPCA + 7.25%, which can improve by 0.4% if ESG goals are achieved, otherwise the rate is increased by 1%.

The Company has loans and financings that are subject to certain financial covenants at the consolidated level, such as: (i) leverage ratio; (ii) capitalization ratio; and (iii) debt service coverage ratio. When applicable, these compliance obligations are standardized for all debt agreements. No changes to the contractual guarantees occurred in the year ended on March 31, 2024.

As of March 31, 2024, the Company was in compliance with all its financial covenants, as well as other qualitative covenants.

(i) As of March 31, 2024, the credit risk-adjusted rate used for Peru was between 11.05% and 14.65% (December 31, 2023: 10.86% and 12.52%) and for Brazil was between 6.67% and 9.17% (December 31, 2023: 6.94% and 11.11%). As of March 31, 2023, the credit risk-adjusted rate used for Peru was between 11.13% and 12.21% (December 31, 2022: 10.92% and 12.04%) and for Brazil was between 8.39% and 9.07% (December 31, 2022: 8.22% and 8.61%).

As part of NEXA’s activities for the execution of certain greenfield projects, the Company has agreed, with the Peruvian Government, to minimum investment levels in the Magistral Project. On February 8, 2024, the Peruvian Government agreed to postpone this commitment from September 2024 to August 2028. As of March 31, 2024, the unexecuted minimum investment commitment was USD 323,000, and if not completed by August 2028, the potential penalty exposure could be USD 97,029.

In addition, Nexa has requested for the Modification of the Environmental Impact Assessment (MEIA) for the Magistral Project. This request is still being evaluated by the competent environmental authority (SENACE); however, the Peruvian Water Authority (ANA) has raised unfavorable observations in relation to Nexa’s request for the MEIA. The final decision from SENACE is still pending and the Company expects to receive an answer in the following weeks. The granting or denial of this environmental permit is relevant and could impact the assessment of the project’s economic feasibility and technical development, as well as the assessment of the recoverability of its assets.

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 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 26,437 (BRL 132,083) for all structures in the state of Minas Gerais which 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, and considerations about risk classification of the dam and inflation for the period. The Company had until March 28, 2024, to submit a proposal, however a new Decree 48,795 of 2024 of Minas Gerais State was published postponing the deadline to submit a proposal until June 28, 2024. The Company may choose the following methods for such environmental guarantee: (i) cash deposit; (ii) Bank Deposit certificate-CDB; (iii) bank guarantee; and (iv) guarantee insurance. The Company expects to be in a position to do so by December 31, 2024, when the Company will have to contract 50% of the guarantee chosen, 25% must be contracted by December 31, 2025, and 25% by the end of 2026.

According to NEXA’s policy, the Company assesses at each reporting date, whether there are indicators that the carrying amount of an asset or CGU may not be recovered or a previously recorded impairment should be reversed. If any indicator exists, the Company estimates the assets or CGU’s recoverable amount.

In 1Q24, Nexa’s management continued to analyze possible alternatives for the Morro Agudo CGU, and during the quarter a binding sale offer was received from a third party for the CGU (as further described in Note 12). Management identified this information as an impairment reversal indicator, which triggered an impairment assessment, as the CGU long-lived assets were totally impaired according to the impairment evaluation performed during 2023. The sale and purchase agreement was entered into subsequently on April 5, 2024.

For the calculation the Company considered the most recent negotiation with the third party, to calculate the fair value less cost of disposal, taking into consideration the sales price and other obligations defined in the offer.

The impairment assessment resulted in the recognition of an impairment reversal of USD 16,216 in the Morro Agudo CGU.

In addition, there was an impairment reversal of USD 1,003 regarding other individual assets mainly related to “Assets and projects under construction”. In summary, Nexa recognized a total impairment reversal of USD 17,219 (after-tax USD 12,170). As of March 31, 2024, and 2023, no other impairment indicator or reversal was identified.

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.

ESG goals for debentures will be assessed in cases of an option that will be enabled on April 1, 2026, related to the early redemption of the integral notes or extraordinary amortization, where the premium paid in the anticipated redemption or amortization will be reduced if Nexa reaches the greenhouse gas emission reduction percentages established in Nexa’s ESG goals framework, for the years 2025 to 2028.

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 April 10, 2024, the Company repurchased an aggregate principal amount of USD 484,504, or 69.2% of the outstanding principal amount of the 2027 Notes in a tender offer for any and all of its outstanding 2027 Notes. On April 15, 2024, the Company repurchased an aggregate principal amount of USD 99,499 or 19.9% of the outstanding principal amount of the 2028 Notes in a tender offer for a portion of its 2028 Notes.

A principal amount of USD 215,496 of the 2027 Notes, and USD 400,501 of the 2028 Notes remain outstanding.
