Highlights

-Nexa Resources S.A. (TSX: NEXA, NYSE: NEXA) (formerly VM Holding S.A.) (“Nexa Resources”, “Nexa”, or the “Company”) announced the completion of its initial public offering. The common shares started to trade on the New York Stock Exchange (“NYSE”) and the Toronto Stock Exchange (“TSX”) under the ticker symbol “NEXA.” on October 27, 2017 and the initial public offering closed effective on October 31, 2017.

-Nexa Resources is a large-scale, low-cost integrated zinc producer with over 60 years of experience developing and operating mining and smelting assets in Latin America. The Company operates and owns five long-life underground mines, three located in the Central Andes of Peru and two located in the state of Minas Gerais in Brazil. Two of the Company’s mines, Cerro Lindo in Peru and Vazante in Brazil, are among the 12 largest zinc mines in the world, and combined with the Company’s other mining operations, place the Company among the top five producers of mined zinc globally in 2016, according to Wood Mackenzie. Nexa also operates three smelting assets, two in Brazil located in the state of Minas Gerais and one in Peru, in Cajamarquilla.

-Mining:

oHigher copper production in the third fiscal quarter of 2017 (or 3Q17) was up 21.7% when compared to 3Q16, partially offsetting a decrease in zinc production

-Smelting:

oStable metallic zinc sales in terms of volume in 3Q17 when compared to 3Q16

-Financial:

oRevenue of US$625.8 million 19.7% higher than 3Q16

Market Overview

Zinc

The average London Metals Exchange (LME) price for zinc in 3Q17 was US$2,963/ton, 31.4% higher than the average price verified in the same quarter of 2016. The price at the end of September was US$3,217/ton.

Voluntary and involuntary mine production cuts in 2015 and 2016 constrained concentrate availability globally, causing a drawdown of concentrate inventories, reaching a critical level equivalent to 30 days of smelter requirement as of September 2016 against 53 days at the end of 2014, according to Wood Mackenzie. In 2017, the smelters continue to reduce metal supply and are shutting down for maintenance due to lower treatment charges (TCs); in China the spot TC was ~US$50/ton as of September 2017 and ~US$90/ton as of September 2016.

During 3Q17, these factors continued to impact the zinc market. Chinese production cuts due to environmental issues also contributed to the current deficit affecting the global market for zinc.

On the demand side, Europe continues to deliver strong performance, as rising consumer and business confidence boosted economic activity and increased demand in the automotive, white goods and construction sectors. Meanwhile, the deceleration of the Chinese real-estate sector and a slowdown in construction investment has been partially offset by an increase in the demand from Vietnam.

Comparing the last day of 2Q17 to September 29th, 2017, the LME spot price for zinc rose 16.8% from US$2,754/ton to US$3,217/ton.

Copper

The average LME copper price in 3Q17 was US$6,349/ton, up 33.0% when compared to the same quarter of 2016. The copper price at the end of September 2017 was US$6,485/ton.

The copper price closed 3Q17 at US$6,485/ton, up 9.8% from June 30, 2017. Higher prices have been supported by demand that exceeded expectation according to Wood Mackenzie. The supply disruptions that occurred at the beginning of the year (including strikes in Chile and Indonesia) have already been remedied, but the market remains concerned about further reductions. A weaker dollar in the period positively impacted copper prices in 3Q17 due to higher costs of non-US operations.

The price recovery in copper following five years of declines has led to a shift in focus by mining companies towards project development, with several major projects gaining approval. Most of the new projects have production startup predicted for 2019+, although high price scenarios may encourage faster mine developments.

Maintenance shutdowns, combined with the factors mentioned above, drove LME stocks to 297kton as of September 29, 2017 compared to 372kton at the end of September 2016 (representing a decrease of 20.2%).

EARNINGS RELEASE 3Q17

Lead

The average LME lead price in 3Q17 was US$2,334/ton, 24.6% higher than the average price verified in 3Q16. The lead price at the end of September 2017 was US$2,519/ton.

In 3Q17, the LME lead price reached a 6-year high of US$2,519/ton due to a critical Chinese refined metal supply constraint evidenced since mid-September 2017. Besides the shortage of lead concentrates observed in the recent months, which was aggravated by the sanctions imposed on North Korean exports (the third largest supplier of concentrates into China so far this year), lead smelters and mines have been facing high levels of environmental inspections resulting in producers halting operations or performing maintenance shutdowns.

Additionally, lead demand remained robust in the Chinese automotive sector, with an increase in vehicle production of 5.1% year-over-year according to August figures. Battery producers and other lead consumer sectors continue to seek alternative source of refined lead, and consequently Shanghai Futures Exchange (SHFE) stocks are close to exhaustion - from 83kt in May 2017 stocks have fallen by the end of 3Q17 to 13.5kt, a decrease of 83.9%, of which just 4.6kt were live warrants (available for purchase). This drop in inventories caused a significant increase in the LME lead price, but not enough to meet SHFE prices, which opened a positive arbitrage and promoted an increase in Chinese imports of refined lead observed in late September 2017.

1Calculated by converting copper, lead, silver and gold contents to a zinc equivalent grade at 3Q17 average benchmark prices. The prices used for this conversion are: Zinc price: US$2,963/ton; Copper price: US$2,334/ton; Lead price: US$6,349/ton; Silver: US$17/oz; Gold price: US$1,278/oz

Avg. % of metal in treated ore (grade)	3Q17	3Q16	3Q17 vs. 3Q16	9M17	9M16	9M17 vs. 9M16

Copper	0.43	0.37	6 bp	0.42	0.40	3 bp
Lead	0.50	0.60	-10 bp	0.51	0.58	-7 bp

The total concentrates of zinc, copper, lead, silver and gold in produced in mining operations totaled 114.0 kton in 3Q17, a 15.9% decrease when compared to the same period of the previous year. The main reasons for lower production volumes were (i) energy supply disruption in Atacocha mine, (ii) lower grades at the Company’s Cerro Lindo mine in 3Q17 and (iii) the revision of processes in order to assure higher safety standards. Copper production increased by 21.7% in 3Q17, partially offsetting the impacts mentioned above. In the first nine months of 2017, concentrate production totaled 344.4 kton, 11.5% lower when compared to the first nine months of 2016.

Smelting Sales Volumes

kton product volume	3Q17	3Q16	3Q17 vs. 3Q16	9M17	9M16	9M17 vs. 9M16

Zinc oxide	10.2	9.7	4.9%	28.8	28.0	3.0%

Sales of metallic zinc were stable compared to 3Q16, due to the higher production at Cajamarquilla smelter (+2.9%) which was mainly due to higher demand for Special High Grade (SHG) products. In the Company’s Brazilian operations, sales were lower in 3Q17 when compared to the 3Q16 (-4.5%) even though the production of the Company’s Brazilian operations was 3.4% higher in 3Q17 against the 3Q16. In the first nine months of 2017, metallic zinc sales were slightly lower when compared to the same period of 2016 (-3.4%).

Note: The information related to each of the nine most recently completed quarters is available on page 15.

Net revenues totaled US$625.8 million in 3Q17, an increase of 19.7% due to higher base metals prices in the global market. The LME zinc price was 31.4% higher than the average of the same quarter of 2016. Copper and lead LME prices also increased by 33.0% and 24.6%, respectively. However, lower concentrate production limited the impact of these price increases.

In the nine months period ended September 30, 2017, net revenues were 23.5% higher compared to the same period of 2016.

Cost of goods sold (COGS) increased by 18.2% due primarily to higher concentrate prices. Process revisions made in order to reinforce safety conditions in the Company’s Peruvian mines impacted costs through 2017, totaling an 18.3% increase in 9M17.

SG&A expenses totaled US$59.5 million in 3Q17, composed of US$22.5 million in selling expenses and US$37.0 million in general and administrative (G&A) expenses. While lower sales volumes resulted in a decrease in selling expenses, G&A expenses slightly increased by 3.3% (or US$1.2 million).

Results for the nine month period ended September 30, 2017 were also impacted by the corporate restructuring within the Nexa Resources business unit, namely the transfer of some corporate employees to Votorantim Metais Zinco S.A. on June 30, 2016.

EARNINGS RELEASE 3Q17

Expenses under Other operating results increased to US$40.9 million in 3Q17 from US$17.2 million in 3Q16. Most of those expenses corresponded to (i) expenses with early stage and greenfield projects (mainly Aripuanã and Shalipayco in Brazil and Peru, respectively) and brownfield mining projects (Vazante and Cerro Lindo in Brazil and Peru, respectively), in particular, expenses related to geological analysis and professional engineering services; and (ii) mining obligations.

In 9M17, Other Operating Results totaled US$90.1 million compared to US$52.4 million in 9M16.

Net financial results amounted to US$25.8 million in 3Q17, compared to a negative total of US$21.6 million in 3Q16, an increase of US$47.4 million. Non-cash foreign exchange gains represented a US$61.4 million variation as a result of the impact of exchange variation on U.S. dollar-denominated debt between our subsidiary Votorantim Metais Zinco S.A. (VMZ) and Nexa Resources. Higher financial expenses, driven by an increase in interest on loans and financing, partially offset those gains.

In the first nine months of 2017, Net financial results totaled negative US$40.1 million compared to US$90.3 in the same period of 2016. As mentioned previously, this variation is mainly due to impact of exchange rate variation on U.S. dollar-denominated debt between VMZ and Nexa Resources.

Net income totaled US$81.0 million in 3Q17, an increase of 67.4% when compared to the amount of US$48.4 million in 3Q16 as a consequence of the impacts mentioned above. Net income totaled US$141.3 million in the nine month period ended 2017, a decrease of 24.7% when compared to the same period of 2016, mainly due to the variation of Net financial results.

Adjusted EBITDA(1) totaled US$161.3 million in 3Q17, a 5.0% increase (or US$7.7million) when compared to the same quarter of the previous year, mostly as a result of the higher net revenues as explained above.

In the first nine months of 2017 adjusted EBITDA totaled US$445.1, 18.2% higher than the same period of 2016.

Key Financial Results

CAPEX

Total capital expenditure (CAPEX1) amounted to US$45.1 million in the third quarter of 2017, mainly impacted by higher investments in tailings dams of Três Marias smelter in Brazil. Of the total CAPEX, 23% was directed towards brownfield expansion projects, aligned with Nexa’s strategy of growing its mining business.

The main expansion project impacting CAPEX in 3Q17 is the ongoing deepening of the Vazante mine. Other brownfield mining projects, including the development of the Trend Ambrosia at the Company’s Morro Agudo mine, are also included in expansion CAPEX. Current investments in early-stage mining projects are considered expenses in operating results (see “Operational Results – Other Operating Results”).

Non-expansion projects account for 77% of total CAPEX. Main non-expansion projects are related to environmental, health and safety investments, maintenance expenditures and investments in tailings dams.

CAPEX for the first nine months of 2017 totaled US$130.7 million (24.8% being expansion and 75.2% non-expansion) compared to US$114.6 in the same period of 2016.

Use of Non-IFRS Financial Measures

Our management uses non-IFRS measures such as Adjusted EBITDA, among other measures, for internal planning and performance measurement purposes. We believe these measures provide useful information about the financial performance of our operations that facilitates period-to-period comparisons on a consistent basis. Management uses Adjusted EBITDA internally to evaluate our underlying operating performance for the reporting periods presented and to assist with the planning and forecasting of future operating results. Management believes that Adjusted EBITDA is a useful measure of our performance because it reflects our cash generation potential from our operational activities excluding exceptional items of the period. These measures should not be considered in isolation or as a substitute for profit (loss) or operating profit, as indicators of operating performance, or as alternatives to cash flow as measures of liquidity. Additionally our calculation of Adjusted EBITDA may be different from the calculation used by other companies, including our competitors in the mining industry, so our measures may not be comparable to those of other companies.

In this Management’s Discussion and Analysis and Earnings Release, we present Adjusted EBITDA, which we define as (i) profit (loss) for the year, plus (ii) profit (loss) from results of associates, plus (iii) depreciation and amortization, plus/less (iv) net financial results, plus/less (v) income tax, less (vi) gain on sale of investment (loss), plus; (vii) impairment of other assets, plus/less (viii) (reversion) impairment—property, plant, equipment. In addition, management may exclude non-cash items considered exceptional from the measurement of Adjusted EBITDA.

We also present herein our net debt, which we define as (i) loans and financing less (ii) cash and cash equivalents, less (iii) financial investments, plus or less (iv) the fair value of derivative financial instruments. Our management believes that net debt is an important figure because it indicates our ability to repay outstanding debts that become due simultaneously using available cash and highly liquid assets.

and statements as to management’s expectations with respect to the business and operations of the Company.

Forward-looking statements are necessarily based upon a number of factors and assumptions that, while considered reasonable by management, are inherently subject to significant business, economic and competitive uncertainties and contingencies. Statements concerning future production costs or volumes are based on numerous assumptions of management regarding operating matters and on assumptions that demand for products develops as anticipated, that customers and other counterparties perform their contractual obligations, that operating and capital plans will not be disrupted by issues such as mechanical failure, unavailability of parts and supplies, labour disturbances, interruption in transportation or utilities, adverse weather conditions, and that there are no material unanticipated variations in the cost of energy or supplies.

We assume no obligation to update forward-looking statements except as required under securities laws. Further information concerning risks and uncertainties associated with these forward-looking statements and our business can be found in our public disclosures filed under our profile on SEDAR (www.sedar.com) and on EDGAR (www.sec.gov).
