Principal events and transactions

(a)

COVID-19 outbreak impacts on NEXA financial statements and operations

In March 2020, the World Health Organization characterized the current COVID-19 disease (“COVID-19”) as a pandemic. Since then, COVID-19 spread across the world with severe effects that impacted the global economy in general and the Company’s business. As a response to COVID-19, the Company implemented and continues to implement additional safety procedures in all its operations to ensure the health and safety of its employees, contractors and communities.

The Company also remains committed to the continuity of its business and has implemented measures to mitigate and reduce the impacts COVID-19 had and could still have on its operations, supply chain and financial condition.

Government authorities in the countries in which the Company operates, especially in Peru, have implemented policies in response to the COVID-19 global outbreak, which affected the Company’s financial position, results of operations and cash flow for the nine-month period ended on September 30, 2020, mainly during the second quarter of 2020.

In this context, in Peru, on March 15, 2020, the government declared a state of emergency in response to COVID-19, imposing operating restrictions on non-essential industries, which included the mining sector. The restriction period was continuously extended until May 10, 2020 and consequently, mining operations at Cerro Lindo, Atacocha and El Porvenir were suspended during this period and the operation of the Cajamarquilla smelter was reduced to approximately 50% of its production capacity. After the end of the state of emergency, operations at the Cerro Lindo and El Porvenir mining units began a gradual ramp up following personnel mobilization restrictions and strict health and safety protocols. Currently, Cerro Lindo and El Porvenir continue to operate subject to additional measures to control and mitigate the spread of COVID-19. The safety protocols implemented at each of the mines for incoming site personnel continue to limit the size and range of activity of the workforce available on site. Considering COVID-19 and its impact on the macroeconomic environment, the uncertain time for recovery and the Company’s efforts to reduce costs and improve operational efficiency, in June, the Company decided to keep operations of the higher-cost Atacocha underground mine suspended. Currently, the Company has still not defined how long this suspension will last and the decision will depend both on the duration and severity of the economic uncertainty related to COVID-19 and on an improvement in the mine’s economic viability. The Company has accrued a total of approximately USD 8,141 as of September 30, 2020 (USD 3,406 as of June 30, 2020) mainly of employee termination costs related to this suspension, which is the Company’s best estimate as of September 30, 2020. The Company expects these termination payments to be completed in the coming months.

In Brazil, the Company’s mining and smelting operations have been operating normally, with the exception of the Juiz de Fora smelter which operated at 60% of its normal production capacity in May and June, in anticipation of lower market demand due to global economic conditions. Beginning in July, this smelter returned to operate at close to full production and is expected to do so for the remainder of the year. Construction activities at the Aripuanã project continue to progress and production is scheduled to start in the beginning of 2022. The original project timeline was extended and the original capital expenditures estimates were revised upward following a comprehensive study of unanticipated external factors and internal issues, such as the delays in the project’s detailed engineering studies, which affected the estimated investment in mine development, consumables and spare parts; the additional infrastructure services due to issues experienced during earthworks activities; the impact of COVID-19; among others.

Although the Company’s operations continue their return to normal, the ultimate impact of the COVID-19 global outbreak on the Company’s financial performance, financial condition and cash flows, depends on its continuing duration and severity, on the efforts to contain its spread and on the impact of measures taken by the Company, governments and others in response. A new period of disruption or an extended global recession caused by the outbreak, could materially and adversely impact the Company’s results of operations, access to sources of liquidity and overall financial condition. As disclosed below, the Company has taken and continues to take measures to strengthen its cash position and enhance its short-term liquidity. Refer to note 22 for additional information.

Unwinding of derivative financial instruments

On July 02, 2020, the Company unwound two derivative financial instruments at their respective mark to market (“MTM”) values at such date. As a result of this transaction, NEXA received net proceeds in cash of USD 3,691, which are included in the Cash Flow statement, in Operating activities. Also, an expense of USD 7,022 was registered in the Income statement, in Other financial items net, considering the difference between the MTM values on July 2nd and those registered as of June 30, 2020.

These derivatives were used to mitigate the exposure to the foreign currency risk associated with changes in the Brazilian real exchange rate:

- Collars, which were contracted in November 2018; and

- A cross-currency swap, which was contracted jointly with a NCE in November 2019.

Basis of preparation of the consolidated financial statements

These condensed consolidated interim financial statements at and for the three and nine-month periods ended September 30, 2020 have been prepared in accordance with International Accounting Standard 34 Interim Financial Reporting (“IAS 34”) using the accounting principles consistent with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”).

The Company made a voluntary election to present the condensed consolidated interim statement of cash flows for the three-month period ended September 30, 2020 and 2019.

The Company is also presenting a condensed consolidated interim statement of changes in shareholders’ equity for the three-month period ended September 30, 2020 and 2019 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 IFRS for annual consolidated financial statements and accordingly should be read in conjunction with the Company’s annual audited consolidated financial statements for the year ended December 31, 2019 prepared in accordance with IFRS as issued by the IASB.

All amounts in thousands of US dollars, unless otherwise stated

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 annual audited consolidated financial statements for the year ended December 31, 2019.

The preparation of the 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. These critical accounting estimates represent estimates that are uncertain and changes in those estimates could materially impact the Company’s condensed consolidated interim financial statements. Actual future outcomes may differ from present estimates and the Company reviews its estimates and assumptions on an ongoing basis using the most current information available. Management also exercises judgment in the process of applying the Company’s accounting policies.

The critical judgments and estimates in the application of accounting principles during the three and nine-month periods ended September 30, 2020 are the same as those disclosed in the Company’s annual audited consolidated financial statements for the year ended December 31, 2019.

The Company reviewed the accounting policies related to the classification of royalties and validity fees in its financial statements during this period. As a result of this review, the Company made some immaterial reclassifications in the 2019 comparable information, which effects are described in notes 5, 6 and 7 to be consistent with 2020.

The COVID-19 pandemic has negatively impacted the Company’s results of operations, cash flows and financial position for the nine-month periods ended September 30, 2020. The Company’s condensed consolidated interim financial statements presented herein reflect estimates and assumptions made by management that affect the reported amounts of assets and liabilities at the date of the condensed consolidated interim financial statements and reported amounts of revenues and expenses during the reporting periods presented. Such estimates and assumptions affect, among other things, the carrying amounts of the Company’s goodwill, long-lived assets, indefinite-lived intangible assets, inventory, deferred income taxes, and the allowance for doubtful accounts. Events and changes in circumstances arising after September 30, 2020, including those resulting from the impacts of COVID-19, will be reflected in management’s estimates for future periods.

These condensed consolidated interim financial statements of the Company for the three and nine-month periods ended September 30, 2020 were approved on October 29, 2020 to be issued in accordance with a resolution of the Board of Directors.

New and amended standards effective January 1, 2020

Several new or amended standards became applicable for the current reporting period. The Company does not expect any changes in its accounting policies or any retrospective adjustments as a result of the adoption of these standards and amendments.

Impact of new standards issued but not yet applied by the Company

During the current reporting period, the IASB issued thirteen new amendments to previously issued standards that are not yet effective and have not been applied by the Company. The Company does not believe that these new standards will have a material effect on its financial statements.

Revision of the condensed consolidated interim statement of changes in shareholders’ equity

The condensed consolidated interim statements of changes in shareholders’ equity have been revised to reflect an adjustment as of January 1, 2020 in the amount of USD 33,650 related to a reclassification affecting the cumulative translation reserve account within Accumulated Other Comprehensive Loss and Additional Paid in Capital in the statement of changes in shareholders’ equity, to correct a misclassification identified in these balances, with no effect to the total shareholders’ equity. This reclassification is not material for any of the periods presented and it has no impact on the Company’s financial position as of December 31, 2019, or the condensed consolidated interim income statement, comprehensive income, changes in shareholders’ equity or cash flows for the three and nine-month periods ended September 30, 2019.

Net revenues		537,826			563,568			1,316,407			1,746,892

(i) Revenues from products decreased in the three-month period ended in September 2020, mainly due to the lower mining production in Peru. Although the Cerro Lindo and El Porvenir mines restarted operations in May and have gradually increased their throughput rates, they were still limited by the size and range of activity of the workforce available on site, during this three-month period.

(ii) Revenues from products decreased in the nine-month period ended in September 2020, mainly due to significantly lower metal prices in the international markets combined with lower mining production due to the government imposed restriction period on the Company’s Peruvian operations, the impact of ramping-up after this restriction period and the continuing limited size and range of

activity of the workforce available on site. This decrease in revenues is also a result of the lower smelting production, due to Cajamarquilla operating at 50% during the restricted period and Juiz de Fora operating at 60% of its capacity in May and June, due to lower market demand resulting from the COVID-19 pandemic.

(iii) For comparative purposes as explained in note 3, 2019 amounts reflect the reclassification of mining royalties from Net Revenues to Cost of sales of USD 146 and USD 355 for the three and nine-month periods ended on September 30, 2019, respectively. The 2020 amounts already consider this reclassification and are comparable.

For the nine-month period, raw materials and consumables also decreased due to significantly lower concentrate prices combined with the lower production in the Company’s operations, as described in note 4.

(ii) Third-party services decreased in the three and nine-month periods ended in September 2020, mainly due to lower production in the Peruvian mining operations which decreased the services contracted for the mines’ preparation and development, lower maintenance services expenses and other expense reduction efforts.

(iii) Depreciation and amortization decreased in the three and nine-month periods ended in September 2020, mainly due to the reduction in the carrying amount of long-lived assets as a result of the impairment of non-current assets recorded in 2019 and in the first and third quarter of 2020. This decrease is also associated with the lower production in the Peruvian mining operations, since the Company uses the units of production method of depreciation and amortization for certain assets.

(iv) Refer to note 17 for information about idle capacity costs and inventory impairment, both mainly associated with the COVID-19 outbreak.

(v) For comparative purposes as explained in note 3, 2019 amounts reflect the reclassification of mining royalties from Net Revenues and from Other income and expenses, net to Cost of sales of USD 661 and 2,357 for the three and nine-month periods ended on September 30, 2019, respectively. The 2020 amounts already consider this reclassification and are comparable.

(vi) For comparative purposes as explained in note 3, 2019 amounts reflect the reclassification of validity fees from Other income and expenses, net to Mineral exploration and project development of USD 1,512 and 4,616 for the three and nine-month periods ended on September 30, 2019, respectively. The 2020 amounts already consider this reclassification and are comparable.

The decrease in mineral exploration and project development, in the three and nine-month periods ended in September 2020, is mainly related to the Company having revised its short-term capital allocation, temporarily suspended its greenfield projects and reduced its mineral exploration expenses in response to COVID-19. The effects of the temporary suspension of such projects have been reflected in the Company’s cash flow estimates for the impairment tests made as of March 31, 2020 and as of September 30, 2020.

(i) For comparative purposes as explained in note 3, 2019 amounts reflect the reclassification of validity fees from Other income and expenses, net to Mineral exploration and project development of USD 1,512 and 4,616 for the three and nine-month periods ended on September 30, 2019, respectively.

(ii) Since September 30, 2020, the Company is presenting the income and expenses from derivative financial instruments and from the changes in the fair value of loans and financings by their net results, since this is the way how management analyzes these items. Consequently, the Company has adjusted the financial income and the financial expenses subtotals for the comparative periods in the income statement.

(iii) The increase in foreign exchange losses, in the nine-month period ended September 30, 2020, is mainly driven by the significant devaluation of BRL against USD, which affected Nexa Brazil’s financial liabilities denominated in USD by 34% for this period. The amount of USD 86,261 included in the foreign exchange losses, for the nine-month period ended September 30, 2020, is related to the outstanding USD denominated intercompany debt of Nexa Brazil with NEXA (USD 7,225 for the three-month period ended September 30, 2020). Intercompany loan balances are fully eliminated in the consolidated financial statements; however, foreign exchange losses or gains are not eliminated in the consolidated financial statements. As of September 30, 2020, the outstanding intercompany balance is USD 250,177 (December 31, 2019: USD 250,570).

All amounts in thousands of US dollars, unless otherwise stated

(i) The decrease in tax benefits on net operating losses, in the nine-month period ended on September 30, 2020, is mainly driven by the devaluation of the BRL against USD during this period, which affected the Company’s tax credits from the Company’s Brazilian legal entities.

(ii) The decrease in uncertain income tax treatments is mainly related to settlements of certain income tax uncertain positions in Nexa Peru and Nexa Atacocha.

(i) The main effect is related to foreign translation losses and gains. The decrease, as of September 30, 2020, is due to the foreign translation driven by the BRL devaluation against USD during this period.

(d)

Summary of contingent liabilities on income taxes

There are uncertainties and legal proceedings for which it is unlikely that an outflow of economic resources will be required. In such cases, a provision is not recognized. As of September 30, 2020, the main legal proceedings are related to the carryforward calculation of net operating losses and deductibility of foreign exchange losses and other expenses. The estimated amount of these contingent liabilities is USD 167,239 (December 31, 2019: USD 182,380). The decrease in the contingent liabilities on income taxes is mainly driven by the BRL and PEN devaluation against USD during this period.

Financial risk management

Financial risk factors

The Company’s activities expose it to a variety of financial risks: a) market risk (including currency risk, interest rate risk and commodities risk); b) credit risk; and c) liquidity risk.

A significant portion of the products sold by the Company are commodities, with prices pegged to international prices observed in the London Metal Exchange ("LME") and denominated in USD. Part of the production costs, however, is denominated in BRL and Peruvian Soles (“PEN”), and therefore, there is a currencies mismatch between revenues and costs. Additionally, the Company has debts linked to different indices and currencies, which may impact its cash flows

In order to mitigate the potential adverse effects of each financial risk factor, the Company follows a Financial Risk Management Policy that establishes governance and guidelines for the financial risk management process, as well as metrics for measurement and monitoring. This policy establishes guidelines and rules for:

(i) Commodities Exposure Management, (ii) Foreign Exchange Exposure Management, (iii) Interest Rate Exposure Management, (iv) Issuers and Counterparties Risk Management, and (v) Liquidity and Financial Indebtedness Management. All strategies and proposals must comply with the Financial Risk Management Policy guidelines and rules, be presented to and discussed with the Finance Committee of the board of directors, and, when applicable, submitted for the approval of the Board of Directors, under the governance structure described in the Financial Risk Management Policy.

(a)

Market risk

The purpose of the market risk management process is to protect the Company's cash flow against adverse events, such as changes in foreign exchange rates, interest rates and commodity prices.

(i)

Foreign exchange rates risk

Foreign exchange rates risk is managed through the Company’s Financial Risk Management Policy, which states that the objectives of derivative transactions are to reduce cash flow volatility, hedge against foreign exchange exposure and minimize currency mismatches.

All actions related to the market risk management process are intended to protect cash flows in USD, to maintain the ability to pay financial obligations, and comply with liquidity and indebtedness levels defined by management.

Presented below are the financial assets and liabilities in foreign currencies at September 30, 2020. These mainly result from the foreign operations of Nexa Brazil for which the functional currency is the BRL. The increased economic uncertainty and risks due to the COVID-19 global outbreak introduced significant volatility in foreign exchange rates in relation to the USD that impacted NEXA since the Company has foreign operations mainly related to Nexa Brazil.

Intercompany loans balances are fully eliminated in the condensed consolidated interim financial statements. However, the related foreign exchange gains or losses are not and are presented as foreign exchange effects in the financial results. Refer to note 8 for additional information.

		565,150			375,174
Net exposure		(325,876	)		(222,184	)

Because of the COVID-19 global outbreak, foreign exchange rates have become more volatile and therefore the Company has been affected by higher variations in its foreign exchange results.

(ii)

Interest rates risk

The Company's interest rate risk arises mainly from long-term loans. Loans at variable rates expose the Company to cash flow interest rate risk. Loans at fixed rates expose the Company to fair value risk associated with interest rates. Refer to note 22 for further information related to interest rates.

The Company’s Financial Risk Management Policy establishes guidelines and rules to hedge against changes in interest rates that impact the Company’s cash flows of the Company. Exposure to each interest rate is projected until the maturity of the assets and liabilities exposed to the interest rate. Occasionally the Company enters into floating to fixed interest rate swaps to manage its cash flow interest rate risk.

As of September 30, 2020, there have been no significant impacts on the Company’s exposure to interest rate risk as a result of the COVID-19 global outbreak.

(iii)

Commodity prices risk

This risk is related to the volatility in the prices of the Company's commodities. Prices fluctuate depending on demand, production capacity, producers' inventory levels, the commercial strategies adopted by large producers, and the availability of substitutes for these products in the global market.

The Company’s Financial Risk Management Policy establishes guidelines to mitigate the risk of fluctuations in commodity prices that could impact the cash flows of the Company. The exposure to the price of each commodity considers the monthly projections of production, purchases of inputs and the maturity flows of hedges associated with them.

Commodity prices hedge transactions are classified into the following hedging strategies:

Hedges for sales of zinc at a fixed price (Customer Hedge)

The objective is to convert sales at fixed prices to floating prices, observed on the London Metal Exchange (LME). The purpose of the strategy is to maintain the revenues of a business unit linked to the LME prices. These transactions usually relate to purchases of zinc for future settlement on the over-the-counter market.

Hedges for mismatches of quotational periods (Book Hedge)

The objective is to hedge quotational periods’ mismatches arising between the purchases of metal concentrate or processed metal and the sale of the processed metal. These transactions usually relate to purchases and sales of zinc for future trading on the over-the-counter market.

Hedges for the operating margin of metals (Strategic Hedge)

The objective is to reduce the volatility of the cash flow from LME prices for zinc, copper and silver and ensure a more predicable operating margin. This strategy is carried out through the sale of zinc forward contracts. For Nexa Brazil, the transaction also involves the sale of USD forward contracts in order to hedge the operating margin in BRL.

(b)

Credit risk

Trade receivables, derivative financial instruments, term deposits, bank deposit certificates ("CDBs") and government securities create exposure to credit risk with respect to the counterparties and issuers. The Company has a policy of making deposits in financial institutions that have, at least, a rating from two of the following international rating agencies: Fitch, Moody’s or Standard & Poor’s. The minimum rating required for counterparties is A+/A1 (local rating scale) or BBB-/Baa3 (global rating scale). Financial institutions in Peru, where only global rating assessments are available, can meet the Company’s policy provided they have a rating of "BBB-" by at least one rating agency.

The pre-settlement risk methodology is used to assess counterparty risks in derivative transactions. This methodology consists of determining the risk associated with the likelihood (via Monte Carlo simulations) of a counterparty defaulting on the financial commitments defined by contract.

The global ratings are obtained from the rating agencies Fitch, Moody's and Standard & Poor's, and are related to commitments in foreign or local currency and, in both cases, assess the capacity to honor these commitments, using a scale applicable on a global basis. Therefore, both ratings in foreign currency and in local currency are internationally comparable ratings.

The ratings used by the Company are always the most conservative ratings of the referred agencies.

In the case of credit risk arising from customer credit exposure, the Company assesses the credit quality of the customer, considering mainly the history of the relationship and financial indicators defining individual credit limits, which are continuously monitored. The Company performs initial analyses of customer credit and, when deemed necessary, guarantees or letters of credit are obtained to mitigate the credit risk. Additionally, most sales to the United States of America, Europe and Asia are collateralized by letters of credit and credit insurance. Refer to note 16 for additional information.

The following table reflects the credit quality of issuers and counterparties for transactions involving cash and cash equivalents, financial investments and derivative financial instruments. The variations presented are mainly related to the Company's transactions in the period and not to changes in the counterparties’ ratings.

(c) Liquidity risk

This risk is managed through the Company's Financial Risk Management Policy, which aims to ensure the availability of funds to meet the Company’s financial commitments. The main liquidity measurement and monitoring instrument is the cash flow projection, using a minimum projection period of 12 months from the benchmark date.

The table below shows the Company's financial liabilities to be settled by the Company based on their maturity (the remaining period from the balance sheet up to the contractual maturity date). The amounts shown represent the estimated undiscounted future cash flow, which include interest to be incurred and, accordingly, do not reconcile directly with the amounts presented in the condensed consolidated interim balance sheet.

In the second quarter, the Company took measures to enhance its short-term liquidity to mitigate the effects of the economic scenario due to the COVID-19 global outbreak on the Company’s cash flows. Such measures included the strengthening of its cash position by incurring new loans and obtaining new financings. As a result, the total amount of financial liabilities, related to Loans and financings, maturing between less than 1 year increased by the amount of USD 132,669. During the third quarter and given that the Company’s operation are returning to normal, as explained in note 1, there was no need to incur any additional liquidity measures. Refer to note 22 for information about debt covenants.

(d) Capital management

The Company’s objectives when managing capital are to safeguard its ability to continue as a going concern, so it can continue to provide returns for shareholders and benefits for other stakeholders; and to maintain an optimal capital structure to reduce the cost of capital.

Nexa Resources S.A.

In order to maintain or adjust the capital structure, the Company may adjust the level of dividends paid to shareholders, return capital to shareholders, issue new shares or sell assets or metals produced to reduce debt. The Company monitors capital mainly using the leverage ratio, calculated as net debt to Adjusted EBITDA.

Net debt and Adjusted EBITDA measures should not be considered in isolation or as a substitute for net income or operating income, as indicators of operating performance, or as alternatives to cash flow as measures of liquidity. Additionally, management’s calculation of Adjusted EBITDA may be different from the calculation used by other companies, including competitors in the mining and smelting industry, so these measures may not be comparable to those of other companies.

(ii) As a result of the lower metal prices in the nine-month period ended September 30, 2020, a provision to reduce inventory costs to net realizable value in the amount of USD 2,934 has been recognized in cost of sales. Any additional economic downturn associated with the COVID-19 global outbreak might impact the Company’s capacity to sell its inventories as global demand for its products decreases. As a result, an additional provision for non-realizable inventories might be required in the future.

All amounts in thousands of US dollars, unless otherwise stated

Due to lower mining production and smelting production in Peru because of the Peruvian government’s mandates in response to the COVID-19 outbreak (as explained in Note 1) and also due to the 40% reduction in production at Juiz de Fora smelting unit in Brazil, in May and June, because of the anticipated lower market demand also associated with COVID-19, the Company recognized USD 73,930 in cost of sales related to abnormal production costs for the nine-month period ended on September 30, 2020. Idle capacity used to determine the abnormal cost of production was calculated using the historical production data of the actual production during the period this idle capacity was estimated. Since August, the Company determined that there was no longer need to recognize any abnormal production costs since the operating units were returning to their projected production.

Impairment of Jarosite project

The Company has reviewed its portfolio of assets and projects under construction and concluded that there are impairment indicators for its projects. Execution of the Jarosite project is suspended and with ongoing studies to conclude its economical and operational viability. The Company used the fair value method to test the Jarosite project for impairment and recorded a further impairment loss in the amount of USD 7,313 for the three-month period ended September 30, 2020, accumulating USD 45,220 for the nine-month period. Expenses related to the project after the aforementioned impairment will be registered as impairment loss in the income statement.

For the impairment calculation, the Company has analyzed each component of the project and classified them as saleable, scrap, or labor expenses directly attributable to the project. Saleable and scrap were evaluated in accordance with the Company’s historical recoverability on sale of assets in accordance with each category, and capitalized labor expenses were written off entirely.

Capital Commitments - Aripuanã Project

At September 30, 2020, the Company had contracted USD 106,888 (USD 211,259 in December 31, 2019) of capital expenditures related to the Aripuanã project for the purchase of property, plant and equipment that have not been incurred yet. The decrease of capital commitments is mainly related to the devaluation of the BRL against USD during the nine-month period ended September 30, 2020, commitments that were agreed in December and were performed during the nine-month period ended, and the reschedule of the project’s operations to January 2022.

Loans and financing transactions during the nine-month period ended September 30, 2020

On February 24, 2020, the Company completed a tender offer to purchase for cash any and all of its outstanding 2023 Notes. Holders of the 2023 Notes tendered an aggregate principal amount of USD 214,530, or 62.55% of the outstanding principal amount as of the date of the offer. USD 128,470 of the 2023 Notes at a cost of 4.625% p.a. remain outstanding. In the transaction the Company also paid an amount of USD 14,481 related to the premium over the notes, which was recognized in the net financial results. Refer to note 8 for additional information on the effect on income statement.

On March 12, 2020, in order to enhance its short-term liquidity, Nexa Peru entered into a term loan with a global financial institution, in the principal amount of BRL 477,000 thousand (approximately USD 100,000) at a cost of 8.5% p.a., with a five-year maturity and an option to prepay before maturity. Simultaneously, the Company contracted a swap to exchange the interest rate to 2.45% p.a. as well as the currency of debt service repayments from BRL to USD. The Company accounted for the term loan under the fair value option to eliminate the accounting mismatch that would arise if amortized cost were used. The term loan is guaranteed by NEXA.

At the end of March 2020, in order to enhance its short-term liquidity in Brazil, the Company entered into four export credit note agreements in the total principal amount of BRL 1,247,000 thousand (approximately USD 250,000) at costs between 134.2% of CDI and CDI + 1.80% up to 4.20%, with maturity dates between 1 and 5 years. All these credit notes were obtained from global financial institutions and can be repaid before maturity.

On April 9, 2020, Nexa Brazil entered into an additional export credit note agreement in the total principal amount of BRL 230,000 thousand, representing USD 45,297 approximately, registered in the date of the received cash, at a cost of CDI + 3.90%, with a one-year maturity. The export credit note is guaranteed by NEXA.

On April 14, 2020, in order to enhance its short-term liquidity, the Company fully drew down its revolving credit facility in the amount of USD 300,000.

On June 15, 2020, the Company concluded a Bond Offering in the amount of USD 500,000, with a maturity date in January 2028 at an interest rate of 6.50% per year. The interest on the notes will be paid semi-annually commencing on January 18, 2021. The bonds are guaranteed by Nexa Brazil, Nexa Peru and Nexa Cajamarquilla. The funds of this new offering were used to prepay three outstanding debts, as follows:

(i) Related to the changes in the fair value of two debt contracts for which the Company elected to apply the fair value option. The fair value option aims to eliminate the accounting mismatch that would arise if amortized cost were used since such debt contracts have derivative financial instruments contracted to economically modify certain terms of such debt contracts. In the accumulated period, the fair value of the relevant derivative financial instruments resulted in a gain in the total amount of USD 4,325. Therefore, in the nine-months, the net result between the debt contracts and the relevant derivative financial instruments was a loss of USD 132 (excluding the effect of changes in the Company´s credit risk of the financial liability in the amount of USD 10,691, included in other comprehensive income). Below is a summary of these two debt contracts terms:

a. Export Credit Note agreement in the principal amount of USD 90,000, at a cost of three-month Libor + 1.54% p.a., with a five-year maturity. Simultaneously, the Company contracted a swap to exchange the interest index to CDI + 1.30% p.a., as well as the currency of debt service repayments from USD to BRL. However, as mentioned in note 1 (m), this swap was unwound in July, but this debt will still be measured at fair value as initially defined.

b. Term loan in the principal amount of BRL 477,000 thousand (approximately USD 100,000) at a cost of 8.5% p.a., with a five-year maturity. Simultaneously, the Company contracted a swap to exchange the interest rate to 2.45% p.a. as well as the currency of debt service repayments from BRL to USD.

Guarantees and covenants

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 nine-month period ended September 30, 2020. Before the end of June 30, 2020, waiver agreements were concluded as explained below.

The financial covenants are measured annually and semiannually, as required by the debt contracts, and given the impact of the COVID-19 on the Company’s financial situation as of June 30, 2020, the Company obtained waivers in respect of its Leverage Ratio as of June 30, 2020 and as of December 31, 2020 and repaid certain of its debts with Leverage Ratio covenants. NEXA will not be required to measure its Leverage Ratio Covenant until June 30, 2021. These waivers were negotiated in anticipation of a possible breach of the Leverage Ratio at the end of June and December 2020, and the Company paid waiver fees in the amount of USD 2,234.

(i) The increase in additions of labor provisions is related to unfavorable rulings in certain labor lawsuits and administrative procedures for which the Company has updated its provision estimate. This increase was offset by foreign exchange effects and reversals that caused the balance to be at the same level of December 31, 2020.

(ii) The increase in environmental provisions, as of September 30, 2020, is mainly related to the assessment issued by the Peruvian environmental agency that proposed corrective measures on the Company’s mine operations in Peru, as well as further inquiries by said agency.

Impairment of non-current assets

According to NEXA’s polices, every year, the Company performs its annual impairment test on September 30 for the Cash Generating Units (“CGUs”) that have goodwill allocated and every quarter it performs an additional test if impairment indicators are identified for any of its CGUs.

On March 31, 2020, after having identified impairment indicators in the period and executed an impairment test, the Company recognized a total pre-tax impairment loss of USD 446,687 (after-tax USD 368,490) comprised of an impairment loss of USD 179,345 in its Cerro Pasco CGU and an impairment loss of USD 267,342 in its goodwill in Mining Peru (the lowest level within the Company at which the goodwill generated in the acquisition of Nexa Peru is monitored by the Company’s management). This impairment loss, at that time, arose mainly as a result of the decrease in short- and mid-term commodities prices, suspension of production, discontinued projects and increased operating costs. On March 31, 2020, in addition, an impairment loss of USD 37,907 was recognized in the Jarosite project described in note 19.

For the three month-period ended on September 30, 2020, the Company performed its annual impairment test for the CGUs to which goodwill has been previously allocated (Cerro de Pasco, Cerro Lindo and Cajamarquilla) and given that the Company assessed that there were new impairment indicators, as described below in the impairment analysis, that would require an additional impairment assessment of its non-current assets, the Company expanded the scope of this test to include all of NEXA’s CGUs.

After performing the test, the Company recognized an amount of pre-tax impairment loss of USD 56,343 (after-tax USD 42,561) in its Cerro Pasco CGU in the three-month period ended September 30, 2020. This impairment loss arose mainly as a result of a decrease in the market long term zinc price, which is assessed by the Company as part of the strategic planning process which is performed during the third quarter of every year as well as a result of the higher CAPEX to be invested in the Cerro de Pasco CGU. In addition, NEXA recognized an impairment loss of USD 7,313 in the Jarosite project as described in note 19, mainly for additional amounts to be paid to suppliers for services of engineering and construction provided; and, an amount of USD 2,075 in individual assets under construction.

In summary, for the nine-month period ended September 30, 2020, the Company has recognized a total impairment of USD 550,325, comprised by USD 267,342 in goodwill in Mining Peru, USD 235,687 in Cerro Pasco CGU, USD 45,220 in Jarosite Project and USD 2,075 in individual assets under construction.

The impairment loss represents the excess of the carrying amount of the assets over their respective fair values less costs of disposal (“FVLCD”).

Valuation methods and assumptions for recoverable amount based on FVLCD

FVLCD is an estimate of the price that the Company would receive to sell an asset, CGU or group of CGUs in an orderly transaction between market participants at the measurement date, less the cost of disposal. FVLCD is not an entity-specific measurement but is focused on market participants’ assumptions for a particular asset. FVLCD is estimated by the Company using discounted cash flows techniques and, although the Company considers observable inputs, a substantial portion of the assumptions used in the calculations are unobservable. These cash flows are classified as level 3 in the fair value hierarchy. No CGUs are currently assessed for impairment by reference to a recoverable amount based on FVLCD classified as level 1 or level 2.

Forecast assumptions

The cash flow forecasts are based on management’s best estimates of expected future revenues and costs, including the future cash costs of production, capital expenditure, and closure, restoration and environmental costs. The resulting estimates are based on detailed life of mine and long term production plans. When calculating FVLCD, these forecasts include anticipated expansions (greenfield projects), considering their evaluation and development stage.

The cash flow forecasts may include net cash flows expected to be realized from the extraction, processing and sale of material that does not currently qualify for inclusion in ore reserves. Such non-reserve material is only included when the Company has confidence it will be converted to reserves. This expectation is usually based on preliminary drilling and sampling of areas of mineralization that are contiguous with existing ore reserves, as well as on the historical internal conversion ratio. Typically, the additional evaluation required for conversion to reserves of such material has not yet been done because this would involve incurring evaluation costs earlier than is required for the efficient planning and operation of the producing mine.

For purposes of determining FVLCD from a market participant’s perspective, the cash flows incorporate management’s internal price forecasts. The internal price forecasts are developed using a robust model that incorporates market-based supply, demand and cost data. The internal price forecasts used for ore reserve estimation testing and the Company’s strategic planning are generally consistent with those used for the impairment testing.

Cost levels incorporated in the cash flow forecasts are based on the current life of mine plan and long term production plan for the CGU, which are based on detailed research, analysis and iterative modelling to optimize the level of return from investment, output and sequence of extraction. The mine plan takes into account all relevant characteristics of the orebody, including waste-to-ore ratios, ore grades, haul distances, chemical and metallurgical properties of the ore, process recoveries and capacities of processing equipment that can be used. The life of mine plan and long term production plans are, therefore, the basis for forecasting production output and production costs in each future year.

The discount rates applied to the future cash flow forecasts represent the Company’s estimate of the rate that a market participant would apply having regard to the time value of money and the risks specific to the asset for which the future cash flow estimates have not been adjusted. The Company’s weighted average cost of capital is generally used for determining the discount rates, with appropriate adjustments for the risk profile of the countries in which the individual CGUs operate. With respect to the estimated future cash flows of capitalized exploration assets and development projects, the Company applies a price to net assets value ratio discount in order to reflect the inherent risk of such projects and that are neither adjusted in the discount rate nor in the future cash flows. The discount is based on the stage of the project and type of metal.

The cash flow forecasts were adjusted to reflect potential impacts of the COVID-19 outbreak on the Company and the future projections and operational decisions of the management.

The process of estimating the recoverable amount involves the use of assumptions, projections for future cash flows and judgment. These calculations use cash flow projections, based on approved financial and operational budgets for a five-year period. After the five-year period, the cash flows are extended until the end of the useful life of mine or indefinitely for the smelters. The smelters’ cash flows do not use growth rates in the cash flow projections of the terminal value. Management’s assumptions and estimates of future cash flow used for the Company’s impairment testing of goodwill and non-financial assets are subject to risk and uncertainties, including metal prices and macroeconomic conditions, which are particularly volatile and partially or totally outside the Company’s control. Short-term prices estimated by the Company for 2020 and 2021 reflect the current environment and then, are subject to heightened uncertainty and variability which could significantly impact the valuation of the non-current assets in the future.

Impairment analysis

During the third quarter of 2020, mainly because of the decline in long term zinc prices determined when the Company updated its long-term forecasting, as mentioned above, Aripuanã project costs re-baseline and some increased CAPEX expected for Cerro de Pasco CGU, the Company’s management considered that these indicators could have a material impact on the CGUs recoverable amount and therefore, an estimation of all CGUs recoverable amount was performed.

Below is a breakdown of the CGU’s carrying amount tested for impairment at September 30, 2020:

	Goodwill		Fair value of mining assets (iv)		Other net assets carrying amount		Total carrying amount
Cerro Lindo (i)		-		347,414		252,499		599,913
Cerro Pasco (i)		-		158,793		72,872		231,665
Goodwill		310,938		-		-		310,938
Mining Peru (ii)		310,938		506,207		325,371		1,142,516

Cajamarquilla		92,494		-		584,388		676,882

Três Marias system (iii)		-		-		354,153		354,153
Aripuanã		-		-		248,262		248,262
Juiz de Fora		-		-		102,569		102,569
		403,432		506,207		1,614,743		2,524,382

(i) Includes exploration assets and development projects with capitalized mining rights and development costs allocated.

(ii) Represents the lowest level within the Company at which the goodwill generated in the acquisition of Nexa Peru is monitored.

(iii) Currently Três Marias smelter is integrated with the operations of Vazante and Morro Agudo and, therefore, are considered as a single CGU.

(iv) Corresponds to the fair value of the identifiable assets recorded at the date of acquisition of Nexa Peru in previous years, which is recorded at the consolidated level.

(a)

Key assumptions used in impairment test

The recoverable amount for each CGU was determined based on FVLCD method, which was higher than the value in use.

The Company identified long term metal prices, discount rate and life of mine (“LOM”) as key assumptions for the recoverable amount determination, due to the material impact of such assumptions may cause on the recoverable value. These assumptions are summarized below:

	September 30, 2020		September 30, 2019
Long term Zinc (USD/t)		2,449		2,571
Discount rate (Brazil)		7.82%		7.10%
Discount rate (Peru)		7.22%		6.38%
Brownfield projects - LOM (years)		from 5 to 17		from 8 to 13
Greenfield projects - LOM (years)		from 12 to 18		from 12 to 24

(b)

Impairment loss test process

During the third quarter of 2020, following the determination of the recoverable amount of the CGUs, the Company compared the carrying amount of each CGU with its respective recoverable amount. At this step, the Company identified an additional impairment loss at the CGU Cerro Pasco in the amount of USD 56,343.

Impairment loss – Cerro Pasco

The additional economic impairment loss during the third quarter was identified at the CGU level and is not directly related to a single asset, the loss was allocated in a pro rata basis to the following assets:

(i)

Cerro Pasco CGU

	Carrying amount prior to impairment			Impairment loss			Carrying amount after impairment
Property, plant and equipment		146,240			(21,860	)		124,379
Intangible assets		230,675			(34,482	)		196,193
Other net assets		(145,249	)		-			(145,249	)
		231,665			(56,343	)		175,323

The Company performed a stress test on the key assumptions used for the calculation of the recoverable amount of the CGU Cerro Pasco and Mining Peru goodwill. A decrease of 5% in the long-term LME zinc price to USD 2,326 per ton compared to management´s estimation as at September 30, 2020 would have had resulted in the recognition of an impairment loss of USD 106,157 (or an additional impairment of USD 49,814). Also, an increase of 5% in discount rate compared to management´s estimation as at September 30, 2020 would have had resulted in an impairment loss of USD 65,505 (or an additional impairment of USD 9,162).

(d)

Impairment results – Other CGUs

The impairment indicators identified, during the third quarter, led to a decrease in the recoverable amount of all the Company’s CGUs. However, the effects were less prominent than in the CGU Cerro Pasco and Mining Peru and no impairment loss were identified in other CGUs.

The Company also estimated the amount by which the value assigned to each of these key assumptions must change in order for the CGUs recoverable amount to be equal to their carrying amount:

	Excess over recoverable	Decrease in Long term Zinc (USD/t)			Increase in WACC
Cash generating unit	amount	Change		Price	Change		Rate
Cerro Lindo	346,167	(47	)%	1,298	65	%	11.90	%
Cajamarquilla	101,689	(4	)%	2,354	11	%	8.00	%
Três Marias system	1,137,525	(38	)%	1,518	284	%	30.00	%
Juiz de fora	589,646	(55	)%	1,102	479	%	45.30	%
Aripuanã	412,143	(34	)%	1,616	90	%	14.90	%
Goodwill - Mining Peru	35,229	(5	)%	2,330	5	%	7.60	%

Events after the reporting period
