Nexa Reports Third Quarter 2023 Net Loss of US$63 million and Adjusted EBITDA of US$82 Million

LUXEMBOURG GERMANY / ACCESSWIRE / October 30, 2023 / Nexa Resources S.A. ("Nexa Resources", "Nexa", or the "Company") announces today its results for the three and nine-month periods ended September 30, 2023.

CEO Message - Ignacio Rosado

"In 3Q23, there continued to be downward pressure on metal prices, mainly driven by the persistence of negative external factors, such as inflation in the U.S. leading to still high interest rates and uncertainties about the performance of key sectors of the Chinese economy (e.g., property). Consequently, the prices of our main metals remained at levels below our expectations for the period and slightly lower than the previous quarter.

Faced with this challenging metal price environment, we remain committed to our financial discipline, which includes a portfolio of initiatives focused on cost reduction, CAPEX, and working capital optimization. Some of these initiatives are still being implemented but have allowed us to improve some line items in our 2023 guidance. Furthermore, they also contributed to positive cash flow generation in 3Q23.

On the operational side, as disclosed a week ago, we have revised Aripuanã's production range downwards for the year, given primarily to the limitations related to the designed capacity of the flotation pumping system, which also resulted in the extension of the ramp-up phase. However, during 3Q23, we continued the ramp-up phase in a structured and disciplined manner, maintaining recoveries and improving the concentrate quality and grades. We are focused on ensuring safe and steady production by processing the zinc concentrate produced in our smelters while expanding sales of lead and copper concentrates.

With respect to our mineral exploration plan, we are moving forward with special attention to expanding the resource and mineral reserves base in our current mines. Additionally, on the growth front, we are making progress with the advanced studies related to the Pasco Integration Project.

Looking ahead, our priorities are the completion of the Aripuanã ramp-up phase, our capital optimization initiatives and the proactive adoption of appropriate measures to maintain a healthy balance sheet, such as the reinforcement of our liquidity through the new 5-year sustainability-linked revolving credit facility of US$320 million, which replaces the previous line that was due to expire in October 2024.

Lastly, we are confident in the long-term fundamentals of our industry and our business. As always, we will continue to focus on safety, productivity, our ESG commitments, and cost control to create value for all of our stakeholders."

Executive Summary

Operational Performance

• Zinc production of 87kt in 3Q23 rose by 15% compared to 3Q22, mainly explained by the increase in treated ore volume and the beginning of production in the Aripuanã mine. Compared to 2Q23, zinc production increased by 8%, primarily due to the higher volumes from the Cerro Lindo, Vazante and Morro Agudo mines, in addition to further production from the Aripuanã ramp-up.
• Run-of-mine mining cost in 3Q23 was US$44/t, up 1% from 3Q22. Compared to 2Q23, run-of-mine mining cost was relatively flat.
• Mining cash cost net of by-products^[1] in 3Q23 was US$0.35/lb compared with US$0.57/lb in 3Q22. This decrease was primarily due to higher by-products contribution driven by higher lead prices and higher copper concentrate volumes. Compared to 2Q23, mining cash cost net of by-products decreased by 6% from US$0.37/lb explained by higher zinc volumes produced, which was partially offset by lower by-products-contribution.
• The smelting segment delivered total production (zinc metal and oxide) of 150kt, down 6% from 3Q22, mainly driven by lower volumes in Cajamarquilla and Juiz de Fora. Compared to 2Q23, production was up 1%.
• In 3Q23, zinc metal and oxide sales were 154kt, down 5% from 3Q22, following lower production volumes, in addition to lower domestic demand for oxide in the period. Compared to 2Q23, metal sales grew 3% driven by higher production volumes and sales strategy in line with working capital improvement initiatives.
• Smelting conversion cost was US$0.29/lb in 3Q23 compared with US$0.26/lb in 3Q22 due to higher maintenance, personnel costs and energy expenses impacted by inflation in the period. Compared to 2Q23, conversion cost was down US$0.03/lb.
• Smelting cash cost¹ was US$1.01/lb in 3Q23 compared with US$1.36/lb in 3Q22 and compared with US$1.12 in 2Q23. In both periods, the decrease was mainly explained by lower zinc prices, which reduced concentrate purchase costs.

[1] Our cash cost net of by-products credits is measured with respect to zinc sold.

Aripuanã

• As previously disclosed in our press release dated October 24, 2023, at the beginning of 3Q23, the plant performance was averaging above 75% of nameplate capacity. We then observed design limitations in the capacity of the flotation pumping system, identified during the detection of bottlenecks in March, which required resizing and upgrade along with certain plant processing facilities and systems, as well as the clean-up and upgrading of water treatment facilities, which will also contribute to a better resiliency during the rainy season (which is expected to run from December to March). Due to the aforementioned limitations, in 3Q23 we reduced plant throughput and, as a result, the utilization rate was also reduced in the period and the plant performed at an average of 56% in the quarter. Despite this reduction, our priority is to continue improving metal recovery and concentrate quality and grades, aiming to achieve a stable operation and to minimize impacts related to the needed extension of the ramp-up phase. With this revised plan in place, we expect to gradually return to an average of 70% capacity utilization level during 4Q23 and reaching 100% of nameplate capacity in 1H24.

Financial Performance

• Net revenues in 3Q23 were US$649 million compared with US$703 million in 3Q22. This decrease was mainly due to lower zinc LME metal prices and smelting sales volume. Compared to 2Q23, net revenues increased by 4%, because of higher mining production and metal sales volumes, partially offset by lower LME metal prices. In 9M23, net revenues amounted to US$1,943 million, down by 14% compared to the same period a year ago.
• In 3Q23, net loss was US$63 million, totaling US$182 million in 9M23, resulting in a basic and diluted losses per share of US$0.56 and US$1.48, respectively.
• Adjusted EBITDA^[2] in 3Q23 was US$82 million, compared with US$121 million in 3Q22 and US$72 million in 2Q23. This performance was mainly driven by lower zinc LME metal prices (Zn down 26% vs 3Q22 and 4% vs 2Q23). Compared to 2Q23, the lower zinc LME metal prices was offset by lower costs in Brazil and higher treatment charges ("TCs") applied to concentrate purchases from third-parties. In 9M23, Adjusted EBITDA amounted to US$286 million, down by 55% compared to the same period a year ago.
• Adjusted EBITDA for the mining segment in 3Q23 was US$40 million compared with US$20 million in 2Q23. This increase was mainly driven by higher volumes in Cerro Lindo, El Porvenir and Vazante, in addition to lower operational costs in Aripuanã, related to concentrate and stockpile costs, which were partially offset by lower LME metal prices. Compared to 3Q22, Adjusted EBITDA decreased by 37%.
• Adjusted EBITDA for the smelting segment in 3Q23 was US$49 million compared with US$51 million in 2Q23. This decrease was mainly driven by the negative hedge variation and lower by-products contribution, which were partially offset by higher TCs and higher sales volume. Compared to 3Q22, Adjusted EBITDA decreased by 16%.
• Adjusted net loss in 3Q23, was US$49 million, totaling US$34 million in 9M23. Adjusted net loss attributable to Nexa's shareholders was US$57 million in 3Q23 and US$53 million in 9M23, resulting in adjusted basic and diluted loss per share of US$0.43 and US$0.40, respectively.

[2] Adjusted EBITDA exclude the items presented in the "Net income (loss) reconciliation to Adjusted EBITDA" section on page 13 of this earnings release - US$15 million in 3Q23, totaling US$148 million in 9M23.

Financial Position, Investments and Financing

• Total cash^[3] at September 30, 2023, was US$422 million compared to US$421 million at June 30, 2023. Our available liquidity in 3Q23 remained at US$722 million, including our revolving credit facility of US$300 million. Nevertheless, on October 20, 2023, we successfully closed a US$320 million sustainability-linked revolving credit facility. This new facility, with a term of 5-year, replaced Nexa's 2019 US$300 million revolving credit facility.
• In 3Q23, our free cash flow generation was US$14 million, mainly due to the positive impact of working capital variations of US$95 million, a result of a reduction in inventories and increase in trade and confirming payables, which were partially offset by an increase in trade accounts receivables, and by investments in sustaining CAPEX (including HS&E investments) in the amount of US$75 million, including US$20 million related to Aripuanã. Refer to our "Net cash flows from operating activities excluding working capital variations and free cash flow - Reconciliation" section for further details.
• Net debt to Adjusted EBITDA ratio for the last twelve months ("LTM") increased to 3.06x compared with 2.83x at the end of June 2023 and 1.41x at the end of 3Q22. This increase was mainly explained by lower LTM Adjusted EBITDA, impacted in part by lower metal prices, while total debt remained relatively flat.

Furthermore, we continue to advance the required environmental studies and permits. As studies progress, the project continues to demonstrate potential to unlock important value for Nexa through economies of scale, costs improvements and extension of asset life.

Outlook

Production, Sales and Cash Cost Guidance

• Nexa will continue to monitor risks associated with global supply chain disruptions, which could be exacerbated, among other factors, by the ongoing Russia-Ukraine war, as well as the Israel-Hamas conflict, unusual weather conditions and/or increased restrictions related to the COVID-19 pandemic; the global recession, and the potential impact on the demand for our products; inflationary cost pressure; metal prices; and community protests, political situation and changes to the regulatory framework in the countries in which we operate that could affect our production levels and our costs. Refer to "Risks and Uncertainties" and "Cautionary Statement on Forward-Looking Statements" for further information.
• Nexa reiterates its 2023 production guidance for all metals, except for the Aripuanã mine, which guidance was updated due to the reasons aforementioned. Zinc metal sales, consolidated cash cost for mining and smelting, capital expenditures, exploration, project evaluation and other expenses are outlined below.
  • Cerro Lindo: zinc and copper production is expected to slightly increase in 4Q23 due to the ongoing mining plan, which encompasses higher-grade stopes. These areas were restricted in 2Q23 after the rainfall-related shutdown in mid-March, impacting mine development, and resumed in 3Q23.
  • El Porvenir: the mine is running at full throughput capacity and based on mine sequencing, zinc production in 4Q23 is expected to slightly decrease compared to 3Q23. However, lead and silver production are expected to increase due to estimated higher average head grades for those metals.
  • Atacocha: the mine is currently running at full throughput capacity and all metals production is estimated to increase in 4Q23 compared to 3Q23, driven by the expected production recovery after the illegal protest activities that took place in June and July.
  • Vazante: ore throughput and zinc head grade in 4Q23 are expected to slightly decrease compared to 3Q23, resulting in lower zinc production, given the mine sequencing plan for the period. Nonetheless, production for 2023 is expected to reach the upper range of the guidance.
  • Morro Agudo: zinc production in 4Q23 is expected to remain at a similar level to the average of 3Q23. Lead production is expected to decrease compared to 3Q23 due to the estimated lower average head grade.
• Aripuanã: the overall ramp-up is expected to improve in 4Q23 compared to 3Q23. The utilization rate at the plant is expected to increase gradually, reaching 70% in the quarter. However, we may expect some additional impact on 2024 production. The 2023 production guidance was revised downwards as previously disclosed in our press release on October 24, 2023.
• Zinc metal sales guidance also remains unchanged at 580-605kt.
  • Peru: we expect production at Cajamarquilla in 4Q23 to be higher than the average in 3Q23, mainly driven by better performance and production stability.
  • Brazil: in Três Marias we expect production to slightly increase in 4Q23 compared to 3Q23, following production stability, while Juiz de Fora production is expected to remain at similar level to the average in 3Q23.
