**1.1** **Main events for the three-months ended on March 31, 2026**<br>

**(a)** **Dividends distribution and share premium reimbursement** 

**NEXA**

On February 26, 2026, the Company's Board of Directors recommended, subject to approval by the Company's Annual General Meeting expected to be held on June 26, 2026, a cash distribution to the Company's shareholders of approximately USD 17,454 to be paid on August 26, 2026, as share premium reimbursement, in accordance with the dividend policy effective since January 2025. As formal approval by the Annual General Meeting had not yet occurred as of the reporting date, no liability has been recognized in respect of this distribution.

**Pollarix**

On January 19, 2026, Pollarix paid dividends related to prior quarters, totaling USD 31,882 (BRL 167,880). Of this amount, USD 25,324 (BRL 133,345) was paid to non-controlling interests and USD 6,558 (BRL 34,535) was paid to Nexa BR.

On March 20, 2026, Pollarix's Management approved at the Company's Annual General Meeting, the dividends related to prior earnings, totaling USD 14,016 (BRL 73,806), with USD 2,883 (BRL 15,183) allocated to Nexa BR and USD 11,133 (BRL 58,623) allocated to non-controlling interests.

**(b)** **Tax claim payments** 

In January of 2026, the Company paid USD 12,210 regarding specific Peruvian uncertain income tax positions, as explained in note 8 (c). Part of this amount, totaling 8,319, was recorded under *"other assets"* as *"tax claim payments"*.

**(c)** **New loans and financing operations** 

On March 4, 2026, the Company entered into an Export Prepayment Loan agreement ("ACC") for a principal amount of USD 40,000, at an annual rate of 4.69%. The loan matures in 6 months and is repayable in a single installment upon submission of supporting exports documentation. Further information regarding this transaction is disclosed in note 15.

**(d) Iran conflict impacts on the Group´s financial statements and operations** 

The ongoing conflict between the United States and Iran, including geopolitical tensions and retaliatory measures, has created global security concerns and economic uncertainty, including the possibility of expanded regional or global conflict. These developments have had, and are likely to continue to have, adverse impacts globally. Potential ramifications include disruption of the supply chain, which may impact production, investment, and demand for the Group's products, higher and more volatile prices for oil and gas, volatility in commodity prices, and disruption of global financial markets, further exacerbating overall macroeconomic trends including inflation and rising interest rates. As of the date of this report, the Group has not identified any material impacts on its operations, financial condition, or cash flows. However, the Group cannot predict the potential future impact of these developments on its business and operation and continues to closely monitor the situation.

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 (iv) 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 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 segment results and reconciliation to income before income tax in the consolidated income statement is as follows:

3 Basis of preparation of the condensed consolidated interim financial statements

These condensed consolidated interim financial statements as at and for the three months ended on March 31, 2026, 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, 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, 2026, and 2025. The Company is also presenting a condensed consolidated interim statement of changes in shareholders' equity for the three-month period ended on March 31, 2026, and 2025 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, 2025, 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, 2025.

The Company has not early adopted any new standards, interpretations or amendments that have been issued but are 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 end period. 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 on 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, 2026, are the same as those disclosed in the Company's audited consolidated financial statements for the year ended on December 31, 2025.

These condensed consolidated interim financial statements for the three months ended on March 31, 2026, were approved on May 05, 2026, to be issued in accordance with a resolution of the Board of Directors.

(i) Gross billing increased in the three-month period ended March 31, 2026, compared to the same period in 2025, mainly due to higher sales volume in Peru, driven by increased billing of zinc, lead, copper concentrates and silver, supported by increased metal prices.

(i) As of March 31, 2026, the Company recognized USD 9,580 in cost of sales related to idle capacity, mainly attributable to operational disruptions affecting production levels, including USD 7,995 at El Porvenir due to a mechanical incident and seismic events, and USD 1,585 at Atacocha due to a 23- day stoppage caused by local community-related disruptions at the San Gerardo open pit, which was subsequently resolved. As of March 31, 2025, the Company recognized idle capacity costs totaling USD 2,888 related to idle capacity in Juiz de Fora due to the temporary shutdown of an emissions control system, which was subsequently resolved.

(ii) Raw materials and consumables increased in the three-month period ended March 31, 2026, compared to the same period in 2025, mainly due to higher sales of refined zinc to the external market at the Nexa Resources Cajamarquilla ("Nexa CJM") smelter and higher LME prices, resulting in increased production levels and, consequently, greater consumption of raw materials and consumables.

(i) The amounts for the three-month period ended in March, 31 2026, are mainly related to exchange-rate variations on USD- denominated accounts receivable and payable between Nexa BR and NEXA, as well as on intercompany loans between Nexa BR and its related parties, for which the exchange variation is not eliminated in consolidation, and on foreign-currency denominated loans. These transactions were affected by the volatility of the Brazilian Real ("BRL"), which strengthened against the USD in 2026.

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

As of March 31, 2026, the Company's main uncertain tax positions are related to: (i) the interpretation of the application of the Cerro Lindo tax stability agreement; (ii) litigation of transfer pricing adjustments over transactions made with related parties; and (iii) the deductibility of certain costs and expenses.

The estimated amount of contingent liabilities related to these uncertain tax positions that have not been recognized in the balance sheet as of March 31, 2026, amounts to USD 349,954 (USD 362,147 on December 31, 2025). Of this amount, USD 164,232 corresponds to matters associated with the Cerro Lindo tax stability agreement and the deductibility of certain costs and expenses. The decrease of USD 2,958 compared to December 31, 2025 (USD 167,190) is mainly due to the recognition of interest and the effect of exchange rate variation.

With respect to Cerro Lindo 2019 tax stability discussion, during the first quarter of 2026, the Company paid USD 12,210 to obtain a 60% reduction in penalties and interest, without affecting its legal position that it is more-likely-than-not that these tax positions will be sustained upon examination. Of this amount, USD 3,891 was offset against part of the tax liability previously recognized, and USD 8,319 was recognized as "tax claim payments" under "other assets". Such payment has been submitted to the courts, and a provision may be recognized for this balance if the likelihood of loss becomes probable, or the payments may be recoverable in cash if the Company prevails in these proceedings.

The provision for tax uncertainties related to the Cerro Lindo tax stability agreement amounted to USD 123,818 (USD 130,709 as of December 31, 2025) and is recognized under "Tax Liabilities" in the balance sheet.

In addition, the total amount paid and recorded as *"tax claim payments*" under "*other assets*", related to the Cerro Lindo tax stability discussions for the 2018 and 2019 tax periods and transfer pricing discussions, totaled USD 132,368 as of March 31, 2026 (USD 125,670 as of December 31, 2025). These payments do not constitute an acknowledgment of liability. They arise from ongoing legal proceedings for which the Company has not recognized a provision but was required to make such payments to continue pursuing its legal defense before the competent authorities.

Except for the movements described above, there were no significant changes in the nature or status of the Company's uncertain tax positions compared to those disclosed in the consolidated financial statements for the year ended December 31, 2025, to which reference is made for further details.

(i) On December 16, 2025, the Company entered into gold and silver Zero Cost Collar ("ZCC") derivative contracts to hedge forecasted revenues, aiming to mitigate commodity price risk in its Peruvian operations during 2026. The instruments have monthly maturities through December 2026 and limit downside price risk while capping upside exposure.

(ii) On March 28, 2025, NEXA entered into a cross-currency swap with a notional amount of USD 112,652 (BRL 650,000 at the transaction date) to hedge the BRL exposure related to Nexa BR debentures maturing in 2030. The instrument mirrors the debentures' cash flows, is measured at FVTPL, and its effects are recognized in net financial results.

(i) During 2026 and 2025, changes in fair value increased for future deliveries due to higher forward copper prices in the long term. However, this effect was partially offset in the same periods, when copper prices exceeded the price cap, reducing the financial instrument liability related to these sales transactions, with revenue recognized at fair value.

(ii) Since June 2023, the Company has been delivering copper concentrates under an offtake agreement, signed in January 2022 (amended in July 2023), to sell 100% of the copper concentrate produced at Aripuanã for a period of 5 years or until NEXA fulfills the delivery of the specified agreed volume. The Company estimates that the full committed copper volumes will be delivered by the end of 2029. The transaction price under the agreement is below current market prices due to a price cap established in the contract.

(i) Finished products increased during the three-month period ended March 31, 2026, compared to the same period in 2025, mainly reflecting higher zinc concentrate inventories in Nexa Peru and Nexa Cajamarquilla, driven by temporary period-end build-ups resulting from timing effects between production and dispatches. This increase also reflects normal commercial and logistics timing, as well as higher inventories at Nexa Resources US ("Nexa US"), consistent with the strategy to expand market share.

(ii) Semi-finished products increased during the three-month period ended March 31, 2026, compared to December 31, 2025, mainly reflecting higher inventories at Nexa BR driven by production dynamics and shipment timing. The increase also reflects inventory management initiatives, including optimization of blend composition, advance purchases of imported materials with longer lead times, and the build-up of strategic inventories to support operational continuity. Additionally, higher LME prices contributed to the increase in certain inventories. This was partially offset by lower zinc calcine and zinc sheet inventories at Nexa CJM, mainly due to a temporary roaster shutdown and higher material consumption in leaching and electrolysis.

(iii) Inventory provisions increased during the three-month period ended March 31, 2026, compared to the same period in 2025, mainly due to higher slow-moving provisions at Nexa BR, primarily related to maintenance materials.

(i) The adjustment arises from the derecognition of a right-of-use asset ("ROU") following its classification as a finance sublease under IFRS 16. Accordingly, the ROU asset was replaced by a sublease receivable (net investment). Furthermore, there was no termination or early settlement of the head lease, which remains recognized as a lease liability.

(i) As of March 31, 2026, the credit risk-adjusted rate used for Peru ranged between 10.71% and 12.86% (December 31, 2025: 5.04% and 10.70%), and for Brazil between 7.51% and 9.95% (December 31, 2025: 7.42% and 12.17%).

(ii) The changes observed in the period ended March 31, 2026, primarily reflect two effects recorded in the remeasurement line: (i) revisions to the disbursement timelines for decommissioning obligations at certain operations, following a reassessment of the expected execution schedule under the existing closure plan; and (ii) updates to discount rates, as described above. As a result, asset retirement obligations for operational assets decreased by USD 13,860 (March 31, 2025: decrease of USD 3,327), as shown in note 12. Additionally, asset retirement and environmental obligations for non-operational assets resulted in a gain of USD 2,657 (March 31, 2025: loss of USD 933), as detailed in note 6.

17 Impairment of long-lived assets

According to Nexa's policy, the Company assesses at each reporting date whether there are indicators that the carrying amount of an asset or a CGU may not be recoverable, or whether a previously recognized impairment loss should be reversed.

As of March 31, 2026, adverse movements in foreign exchange rates (USD/BRL) were identified as an impairment indicator for the Juiz de Fora CGU, as the exchange rate approached the break-even level of USD/BRL 5.23, based on the prior impairment assessment. Therefore, the Company performed an impairment test, using the prior-year impairment test for the Juiz de Fora CGU as the starting point and updating the assumptions that changed during the quarter, including the foreign exchange rate (USD/BRL) and future metal prices, particularly zinc. The impairment test did not result in the recognition of any impairment loss.

As of March 31, 2026, no impairment losses were recognized for any CGU, and no impairment indicators were identified for the Company's other CGUs in Brazil and Peru.

Management will continue to monitor macroeconomic conditions and other factors that may give rise to impairment indicators.

Additionally, as of March 31, 2026, the company recognized an impairment reversal of USD 1,351 related to individual assets (impairment loss of USD 297 As of March 31, 2025), mainly classified under "Assets and projects under construction".
