Rodrigo Cammarosano
Good morning, everyone, and welcome to Nexa Resources fourth quarter and full year 2023 earnings conference call. Thanks for joining us today. During the call, we will be discussing the company’s performance as per the earnings release that we issued yesterday. We encourage you to follow along with this on-screen presentation through the webcast.
Before we begin, I would like to draw your attention to Slide number 2, as we will be making forward-looking statements about our business, and we just ask that you will refer to the disclaimer and the conditions surrounding those statements.
It is now my pleasure to introduce our speakers. Joining us today is our CEO, Ignacio Rosado; our CFO, Jose Carlos del Valle; and our Senior Vice President of Mining, Leonardo Coelho.
So now, I will turn the call over to Ignacio for his comments. Ignacio, please go ahead.
Ignacio Rosado
Thank you, Rodrigo, and good morning to everyone. Please let’s move now to Slide number 3, where we will begin our presentation. We appreciate you joining us today to discuss our fourth quarter and full year 2023 results, along with insights into our outlook for 2024.
I am pleased to report that we achieved our guidance for the year with metal production at the high end of guidance and total smelting sales at the midrange, while mining and smelting costs were in line with guidance. As many of you are aware, 2023 posed persistent challenges to our business, particularly due to zinc prices and the delay in the ramp-up of Aripuanã.
Nonetheless, I would like to highlight the dedication and professionalism of our team, which supported us in improving efficiency across our organization, which enabled us to deliver solid operational results and also to mitigate in part the negative impacts of lower zinc prices in our 2023 cash flow.
For the full year, total consolidated net revenues amounted to $2,573 million, down by 15% year-over-year, mainly due to lower zinc prices and lower metal sales. Adjusted EBITDA in the fourth quarter of 2023 was $105 million compared to $120 million a year ago. This performance was mainly driven by lower smelting sales volumes and zinc prices. Zinc was down 17% year-over-year.
Compared to last quarter, adjusted EBITDA rose 28% due to higher zinc prices, which were partially offset by lower smelting sales volume. For the full year, adjusted EBITDA amounted to $391 million, down 49% year-over-year, primarily driven by lower LME metal prices, in addition to lower smelting sales volume.
I want to reaffirm that we remain focused on completing the Aripuanã ramp-up and consequently reaching the nameplate capacity in the second quarter of this year, maintaining our operational and cost optimization discipline, aiming to generate positive cash flow throughout this year and advancing with a formal approval process for the Cerro Pasco integration project.
Now, I would like to go over the progress of our ESG initiatives. 2023 accurately portrays our efforts to strengthen our sustainable business model. Nexa registered its carbon emissions on the LMEpassport, the London Metal Exchange platform, which promotes sustainability and transparency across the base metal sector.
Nexa’s zinc production has one of the lowest carbon footprints recorded in the sector with an emission intensity of 0.36 tonnes of CO2 equivalent considered as one and two. This achievement positions Nexa as one of the global leaders in carbon reduction within the zinc industry. Moreover, CDP, Carbon Disclosure Project, recently concluded its evaluation cycle for the year 2023 and announced that Nexa’s rating in the Climate Change questionnaire was upgraded, changing from C to B. This recognition is the result of our efforts, disclosure and transparency related to governance, strategy, risk management, metrics and targets.
Now, moving to Slide number 4. Regarding the operating performance of the Mining segment, you can see that zinc production increased to 90,000 tonnes in the fourth quarter of 2023, up 21% year-over-year, mainly explained by higher production at the Aripuanã mine, combined with higher production from the Cerro Lindo mine.
Compared to the third quarter of 2023, zinc production was up 3%, explained by higher volumes from the Cerro Lindo, Atacocha and Morro Agudo mines in addition to additional production from the Aripuanã ramp up. It is important to highlight that in 2023 production was up 12% compared to 2022.
In relation to cash cost, in the fourth quarter of 2023, it increased to $0.45 per pound compared to the $0.20 per pound in the fourth quarter of 2022, mainly explained by lower byproduct rates from our Peruvian mines higher operational costs in El Porvenir and higher treatment charges. Compared to the third quarter of 2023, mining cash cost increased by $0.10 per pound mainly affected by lower byproduct rates from Cerro Lindo and higher operational costs in El Porvenir due to the increase in mine development. The cost per run of mine in the quarter was $48 per ton, up 3% year-over-year, explained by higher variable costs and up 10% quarter-over-quarter also affected by high variable costs.
Now moving to Slide number 5, regarding the operating performance of this smelting segment, metal sales total 143,000 tonnes in the third – of last year, down 14% from the fourth quarter of 2022 and 7% compared to the third quarter of 2023, mainly impacted by lower volumes in Cajamarquilla and Três Marias.
In 2023, total sales were down 4% compared to 2022. The smelting cash cost in the fourth quarter of 2023 decreased to $1 per pound compared to the $1.20 in the fourth quarter of 2022. This decrease was mainly explained by lower zinc prices, reducing the cost of raw materials purchase, which was partially offset by lower byproducts contribution.
Compared to the third quarter of 2023, cash cost was down $0.01 per pound. Our conversion cost was $0.29 per pound compared to the $0.25 per pound in the fourth quarter of – due to higher maintenance and energy costs. Compared to the third quarter of 2023, conversion cost was relatively flat.
Now moving to Slide number 6, where we will talk about Aripuanã. In the fourth quarter, activities in Aripuanã have progressed as planned with our efforts concentrated on further improving plant stabilization and reliability as well as increasing metallurgical performance. In December, we had five days of downtime in the plant to address the replacement of equipment together with the execution of important debottlenecking task force activities.
Considering this downtime, the average plant capacity utilization in the quarter was 61%, 5% higher compared to the previous quarter. In the last quarter, we also saw improvements in zinc recovery while concentrate grades and quality were stable. As a result, there was an increase in production compared to the previous quarter.
Our exploration plan in Aripuanã in the fourth quarter also progressed as expected and the results confirmed the continuity of mineralization with high polymetallic contents, showing that we have a robust mining asset with the potential to operate for many years. We started 2024 with positive progress that keep us confident in estimating the completion of the ramp up in the second quarter of this year. In the next two slides, we will see more details on the operational performance of Aripuanã.
Now moving to Slide number 7, starting with the plant downtime in the upper left side, we noted a decrease of 6% quarter-over-quarter, considering the five days planned downtime, which shows improvements in the stabilization of the plant. Average plant capacity utilization increased to 61% versus 56% in the third quarter.
In the lower left side, we can see the progress of the zinc recovery which reached 66% in December versus 59% in September when compared looking at the January 2024 number, we see that the recovery ratio improved even further reaching 73%. Copper and lead recoveries also improved significantly in January, showing a strong positive trend.
Now moving to a Slide number 8. On a Slide number 8, you can see that due to all the improvements mentioned above, compared to the third quarter of 2023, zinc production was 27% higher, reaching 7,400 tonnes in the fourth quarter.
Copper production increased 31% while lead and silver production grew up 49% and 42% respectively. These improvements show that we are in the right direction to achieve nameplate capacity in the second quarter of this year.
Now moving to Slide number 9. On this slide, I would like to highlight that we continue progressing with our exploration program. The 2023 plan shows indications of positive results for both brownfield and greenfield activities.
In Cerro Lindo, the exploratory drilling program focus on extending the mineralization of the OB-8 and OB-9 mineralized bodies, as well as identifying new mineralized zones at the Pucasalla target and its extensions. For Vazante, the focus was on expanding existing mineralized zones in the northern and southern parts of the mine. In Aripuanã, the program was directed at increasing mineral resources at the Babaçu mineralized body and started drilling at the Massaranduba target.
Both targets have solid indications of potential resource addition with attractive content. Finally, at the Cerro Pasco Complex, the exploration program also showed relevant results. The program focused mainly on the integration target, which I will describe in detail in the next slide.
In the Slide number 10, you can see some of the exploration program results in the Pasco Complex, especially in the target integration that keep suggesting potential resource extensions. The target integration is an exploration area located between the El Porvenir and Atacocha underground mines. The results of this exploration confirm the continuity of mineralization at deeper levels with high metal content. We will continue to explore this area with the aim of not only increasing the mineral inventory, but also increasing the geological potential.
Now, I will turn over the call to José Carlos del Valle, our CFO, who will present our financial results. José, please go ahead.
Jose Carlos del Valle
Thank you, Ignacio. Good morning to everyone. I will continue on Slide 11. As you can see, beginning with the chart on your upper left, total consolidated net revenues for the fourth quarter decreased by 19% year-over-year, mainly due to lower sync LME prices and lower smelting sales volumes. Compared to the third quarter of 2023, net revenues decreased by 3%, also as a result of lower smelter sales volumes, but partially offset by higher zinc prices and higher production in the mining segment.
In 2023, consolidated net revenues reached $2.6 billion, down by 15% compared to 2022. In terms of profitability, consolidated adjusted EBITDA in the fourth quarter of 2023 was $105 million compared to $120 million in the fourth quarter of 2022. This lower performance was mainly explained by lower smelter sales volumes and lower zinc prices.
Compared to the third quarter of 2023, adjusted EBITDA increased by 28%, mainly due to higher zinc prices and higher mining production, which was partially offset by lower smelter sales volumes. In 2023, consolidated adjusted EBITDA reached $391 million, down 49% from 2022. This is also explained by the reasons I mentioned a moment ago.
Now let’s move to the next Slide, number 12. On the top left of the slide, we can see that in 2023 we invested $309 million in CapEx, of which sustaining investments, including mine development, totaled $293 million. The total investment in the fourth quarter was $111 million, leaving us within our guidance for the full year. With respect to mineral exploration and project evaluation, we invested a total of $92 million, of which $52 million were related to mineral exploration and mine development to support the exploration activities that Ignacio presented just a moment ago.
The total invested in the fourth quarter was $24 million. This was $8 million below our guidance as we deprioritized some activities as a result of the cash optimization program that we developed throughout the year.
Now let’s move on to the next slide in which I will discuss our cash flow. For 2023, starting from the $391 million of adjusted EBITDA, net of non-operational items, we paid $170 million related to interest and taxes and spent $309 million in total CapEx in our operations, including Aripuanã.
Additionally, loans and investments and dividends received had a positive net impact of $66 million, mainly due to a new $50 million export financing line that became effective in December. Furthermore, dividends paid had a negative impact of $49 million, including the payment of share premium to Nexa shareholders and the contractual dividends paid to non-controlling interests.
We then had a positive impact of $8 million due to the effects of foreign exchange on our cash and cash equivalents, driven by the appreciation of the Brazilian real against the U.S. dollar during the period. Additionally, we had a positive contribution of $101 million in working capital as a result of the efforts deployed throughout 2023 which focus on shortening our working capital cycle. Combining all these effects, our free cash flow in 2023 was negative $41 million.
Finally, on the top right of the slide, we can see the evolution of our free cash flow generation quarter-over-quarter. Our operational and cost discipline, together with the improvements in working capital throughout the year enabled us to generate positive cash flow in the last three quarters of 2023, despite the external and internal challenges we faced.
Now moving to Slide 14. On this slide, you can see that our liquidity remains healthy and that we continue to present a sound balance sheet with an extended debt maturity profile. By the end of 2023, our available liquidity was approximately $788 million, including our undrawn sustainability linked revolving credit facility of $320 million. Regarding our debt, it currently has an average maturity of 3.8 years and a 6.1% average cost.
It is important to mention that as of December 31, our total cash is sufficient to cover the payment or all obligations maturing in the next three years. Nevertheless, we are always evaluating options to continue to keep a maturity profile that is in line with the long life of our mines and at the most competitive costs.
Finally, despite the $43 million increase in our cash balance, quarter-over-quarter leverage, which is measured by the net debt to adjusted EBITDA ratio, increased from 3.1x to 3.2x in the last 90 days of 2023. This is mainly because of lower adjusted EBITDA in the last 12 months, driven by the prevailing trend of lower zinc prices year-over-year.
Moving now to Slide 15. Regarding market fundamentals, it is worth noting that in the fourth quarter of 2023, LME zinc price averaged $2,498 per ton, down by 17% from the fourth quarter of 2022. The main reason for the decline was a combination of the bullish scenario in 2022, mainly driven by the Chinese post pandemic stimulus and the metal production cuts in Europe due to high energy prices and lower global demand in 2023.
This driven by persistent high interest rates in key economies and lower than expected performance of key Chinese zinc consuming sectors like the property market. Compared to the third quarter of 2023, LME zinc prices were up 3%, mainly related to the expectation of the Federal Reserve rate cuts in 2024 and to stronger demand expected in China.
LME copper price averaged $8,159 per ton in the fourth quarter of 2023, up by 2% from the fourth quarter of 2022 and down by 2% from the third quarter of 2023, also presenting high sensitivity to the Chinese economy throughout 2023.
Looking ahead to 2024, metal prices are expected to be supported by easy monetary policy in the U.S. and macroeconomic stimulus in China. In the mid to long-term, the fundamental outlook for both zinc and copper prices remains positive. Additionally, investments in construction infrastructure and in the automotive sector will continue to have a positive impact on demand expectations for base metals. On the supply side for both copper and zinc, we anticipate that we will continue to see challenges to renew significant production online to fulfill expected demand.
Now, I will hand over the presentation back to Ignacio for his final remarks.
Ignacio Rosado
Thank you, Jose Carlos. On our last slide, I would like to close this presentation by mentioning our priorities for 2024. As we look ahead to this year, we anticipate that volatility across commodities may persist for a while and continue to put pressure on our business.
However, we will remain focused on our priorities, including the completion of the Aripuanã and Cerro Pasco integration project in addition to our commitment to always seek alternatives to optimize costs, CapEx and corporate expenses, as well as strengthen our balance sheet. We will continue our journey as we foster the creation of shared value through operational excellence, environmental protection and the integral development of our communities within a framework of ethics, transparency and responsibility. In summary, although we expect 2024 to be a challenging year, we are confident that the growth of our business and the long-term fundamental of our industry will be key to sustain our position.
That concludes our remarks. Thank you all for attending this presentation. Operator, we are ready to open the floor for questions, please.
Question-and-Answer Session
Operator
Thank you. We will now begin the question-and-answer session. [Operator Instructions] Our first question comes from Camilla Barder from Bradesco. Please go ahead.
Camilla Barder
Hi. Good morning. Thanks for the presentation. Just a quick question on the cost side. If you could provide how you think cost evolving throughout the year for the semesters? And if you also could provide some color on free cash flow expectations, it would be great. Thank you.
Ignacio Rosado
So, regarding cost, as you saw in the presentation, we were able to keep cost flats in our mines in Peru and in Brazil. And this was, I would say, a combination of higher throughput and measures around reducing fixed cost incremental PVD in 2023, we reduce about 500 people in only our operations. And regardless, let’s say, inflation issues, especially in Brazil and some in Peru. And regarding some FX impacts, especially in Brazil, we were able to keep costs flat.
However, there were some costs that we couldn’t control because we needed to develop some mines, such as El Porvenir. We have been taking additional measures for 2024. So the idea is that we also keep our cost of raw flat this year. We are very committed in making sure that all details at the mines and all these measures that we take are being follow up very closely. So we are confident that we might also have this under control for 2024.
Camilla Barder
Thank you. And can you comment on free cash flow expectations as well?
Ignacio Rosado
Well, free cash flow expectations will depend on prices. I would say that this year compared to last year, last year we had two effects on cash flow. The first one there was zinc prices, especially because zinc prices went down heavily on the second quarter. And the second one is that the ramp up of Aripuanã was delayed. And this cost us a lot of money. We’re spending Aripuanã around $200 million last year. And if you see that, and if you see the cash flow generation that we had in the third last quarter, that was positive. It was something that we feel proud of. In 2024, as we said, well, prices remain low, but Aripuanã is in the right track to be online play capacity in the second quarter. So the idea is that if prices go up a little bit, we expect that that is the case. We are in the bottom of the price cycle. We might generate some cash flow in 2024.
Having said that, this cash flow for us is a priority because we have to start reducing our debt, debt went up. We are aware of the leverage we have. And then, debt went up because of Aripuanã mainly. So now that Aripuanã is being completed and is going to start generating cash flow, and with a combination of cash flow for the other mines, we believe that with some help on prices, the company is really in a good position to generate cash.
Camilla Barder
And just to confirm, Aripuanã breakeven is expected in the first semester or the second one?
Ignacio Rosado
Yes. No, to give you some numbers, we are now producing at a rate of 220 hours per ton a day – sorry, an hour. And the nameplate capacity is 280. And we are very close on that. February and January have been good months. Recoveries are high in the three metals. Quality of concentrate is also stable and good. So second quarter, we see achieving nameplate capacity. We are very close on that. So we are confident that in the second quarter, we will be able to achieve that target.
Camilla Barder
I mean, breakeven.
Ignacio Rosado
Yes, breakeven. Yes, a consequence of nameplate capacity – we are working on controlling our costs. So a consequence of nameplate capacity is going to be breakeven as well. So second quarter should – we should achieve breakeven on cash flow, yes.
Camilla Barder
Okay. Thank you very much. And thank you for the presentation.
Ignacio Rosado
Thank you.
Operator
[Operator Instructions] There are no more questions in the question queue. I’ll hand it back to Rodrigo for any webcast questions they may have.
Rodrigo Cammarosano
Hey, thank you, operator. Good morning, everyone. We’re going to start with a question from Omar Avellaneda from Prima AFP. The first question is regarding, is the $300 million your annual sustaining CapEx?
Ignacio Rosado
Yes. No. Yes. $300 million is the CapEx that we have ongoing. Our sustaining CapEx more or less is $230 million or $240 million, and the rest is additional CapEx that we spend on explorations and other areas.
Rodrigo Cammarosano
And the second question, also from Omar is, what is the CapEx for Pasco integration project? And when do you expect to approve the project?
Ignacio Rosado
Yes, it’s a good question. We have been talking about integration during the last year. We expect that CapEx – and we are still fine-tuning; that’s why we haven’t approved the project yet – to be around $150 million to $200 million. This comprises a new piping system that goes from El Porvenir to Atacocha tailing dam; a mine development between the two underground mines in Atacocha and El Porvenir; some upgrade of the shaft and some other developments, especially in Atacocha.
So we are finalizing the studies here, and we expect to approve this project in the coming months. The idea is that we have – we work on – we finish all these studies, we have more certainty on the investments. So we might approve this probably in the second quarter or towards the middle of the year. So we can communicate to the market what will happen in this very important project.
Rodrigo Cammarosano
We have another question from Hernán Kisluk from MetLife. If Aripuanã reaches full capacity in the second quarter 2024, why does the guidance show increased production over the next few years?
Ignacio Rosado
Yes. This is because the first quarter, production was not on 100%. And in the second quarter, as we achieved nameplate capacity, we are also not on 100%. So I would say that if you extrapolate the second half of this year, through the other years, you will achieve the number that we are showing for 2025 and 2026.
Rodrigo Cammarosano
We have another question from Joslyn Jensen. When do you expect to start the leveraging?
Ignacio Rosado
As I was saying, we expect delivering this year. As I said, this is a priority cash flow. We are in good shape in terms of what we can control in our mines and smelters. We are working very hard on production cost and CapEx, but we are exposed to prices, zinc prices did not began the year in a very good pace. So hopefully – and we are confident that they will recover in the following quarter. So with the cash flow that we will start generating, the idea is we start delivering the company.
Rodrigo Cammarosano
We have a question from Rodrigo Murrieta from AFP Integra. Are you evaluating measures to decrease cost of per tonne of raw mat Cerro Lindo going forward?
Jose Carlos del Valle
Yes, Cerro Lindo is a challenge. Cerro Lindo is a big underground mine, probably is one of the largest underground mines in general. Yes, and the cost per tonne of raw mat is $40. And we have to give you an idea in Cerro Lindo as mine development, we have to develop 35 kilometers per year. So – and we have pressures on a given that the mine is extending, we have pressures on all of this. So we have been managing in the last two years to keep these $40 flat.
And this has been a challenge. And as I was saying, we have some consolidation of contractors. We have some measures on productivity, reducing of people. We have some measures reducing costs. We have been optimizing our short grid. That is a support of the mine and many, many other measures. So for us to keep the cost of raw mat – cost per tonne below $40 is a challenge. But we believe that we can achieve that during 2024. 2025 we’ll see, but with the measures we take, the idea is that we keep our cost below $40.
Rodrigo Cammarosano
We have another question. What is the expected CapEx that you are considering for the integration project in Pasco?
Jose Carlos del Valle
Yes. As I said before, between 150 to 200, I already explained what are the components of that. We are still assessing how are we going to finance that? This CapEx is going to be invested in three years. So part of the cash flow generation of Cerro Pasco is going to be allocated to this. And the rest we are assessing, it might be some debt or some other cash flow that we might have from other operations. But still we will communicate that once we go forward.
Rodrigo Cammarosano
Okay. We have another question for Hernán. Can you comment on the alternatives for the Morro Agudo asset?
Ignacio Rosado
Yes. The Morro Agudo asset is a marginal asset for us. It’s a very small asset. And this is not transformational, has a low life of mine, so I cannot comment on specific actions. But what I can tell is that we are assessing in detail what are our options in Morro Agudo. We have provide a guidance for production for 2024, but not for 2025 and 2026, because as I said, this is a marginal asset and we are assessing the options. As soon as we have some clarity on that, we will come back to the market and communicate what are the next steps on this asset.
Rodrigo Cammarosano
There are no more questions in the queue. This concludes our question-and-answer session. We will now hand the call over to Ignacio his final remarks. Mr. Rosado. please go ahead
Ignacio Rosado
Thank you. Thank you everyone for attending. This has been – 2023 has been a very challenging year. As I was saying, Aripuanã, the delay on Aripuanã, a consumer a lot of cash flow. Prices have not been there. As I said, we believe that we are in the bottom of the cycle and we are confident that this year is going to be better. The evolution of Aripuanã and all the measures that we have taken will help us generating cash flow for this year. We are committed to that.
We are committed on our cash discipline and making sure that Aripuanã is up and running. We are hoping that we approve soon the integration project of Cerro Pasco. This is important for the company because it will unlock a lot of value, more life of mine, for sure, because of all these resources that are in the underground part, but also more profitability, given the economies of the scale of the two assets.
So we are committed to that. We are committed to all these measures, and we thank you for the time and we look forward to speak to you at the end of April with our first quarter results. Thank you very much and have a good day.
Operator
Conference has now concluded. Thank you for attending today’s presentation. You may now disconnect.
