Speaker #3: Hi, everyone. Well, thank you, Anna, for showing us this video of our operations. As you can all tell, we're very, very proud of what we've built.

Ana Cabral: Hi, everyone. Well, thank you, Anna, for showing us this video of our operations. As you can all tell, we're very, very proud of what we built here in Vale do Jequitinhonha. Without further ado, I'll go straight into the Q4 2025 earnings release presentation, which covers the entire full year 2025 annual financial results. We're gonna make quite a lot of forward-looking statements, and we would like to encourage you to read the disclaimer of this presentation that's gonna be posted on our video. Sigma is the largest industrial mineral producer in the Americas. We've delivered operational excellence. We are a low-cost operation, and we are executing a high-growth strategy for 2026, 2027, and 2028. This is because we are a management operator company, where our interests are fully aligned with the interests of our shareholders, which are to build long-term value.

Speaker #3: Here in Vale do Jequitinhonha, so without further ado, I'll go straight into the fourth quarter 2025 earnings release presentation, which covers the entire full year 2025 annual financial results.

Speaker #3: We're going to make quite a lot of forward-looking statements, and we would like to encourage you to read the disclaimer of this presentation that is going to be posted on our video.

Speaker #3: Sigma is the largest industrial mineral producer in the Americas. We've delivered operational excellence. We are a low-cost operation, and we are executing a high-growth strategy for 2026, 2027, and 2028.

Speaker #3: This is because we are a management operator company, where our interests are fully aligned with the interests of our shareholders. We are here to build long-term value.

Speaker #3: Our main competitive advantage is our resilience, which comes from operational efficiency. Our efficiency is, again, driven by the fact that the management is owner of the company.

Ana Cabral: Our main competitive advantage is our resilience, which comes from operational efficiency. Our efficiency is, again, driven by the fact that the management is owner of the company. More importantly, we are located in a country in Brazil, which is a politically stable, traditional mining jurisdiction, where we have a very low-cost operating environment. On sustainability, we are 100% sustainable. We have the Quintuple Zero Lithium, which starts with five points. We do not have tailings dams, so zero. We do not use drinking water. 100% of the water is reused and recycled from sewage. Zero. We use zero hazardous chemicals in our operation. DMS is basically a physics-based process, so third zero. We use 100% clean energy, so zero dirty energy. We have had zero accidents with lost time for almost 3 years. Again, a picture is 1,000 words.

Speaker #3: More importantly, we are located in a country in Brazil, which is a politically stable, traditional mining jurisdiction. We have a very low-cost operating environment.

Speaker #3: On sustainability, we are 100% sustainable. We have the quintuple zero lithium. We start with five points. We do not have tailings dams, so zero.

Speaker #3: We do not use drinking water. One hundred percent of the water is reused and recycled. From sewage, zero. We use zero hazardous chemicals in our operation.

Speaker #3: DMS is basically a physics-based process, so third zero. We use 100% clean energy, so zero dirty energy. And we have had zero accidents with lost time for almost three years.

Speaker #3: Again, a picture is a thousand words. Here is a picture of our waste tailings, before and after the artificial germination program. It's blended into the landscape.

Ana Cabral: Here's a picture of our waste tailings before and after the artificial germination program. It's blended into the landscape. It's basically stacked-up rock, fully geotechnically stable. We went through the sustainability initiative of actually planting the rock into a green mountain. What you see now is essentially the picture below. We are 100% sustainable. We produce the Quintuple Zero Lithium. We have zero tailing dams. We have zero drinking water. We have zero hazardous chemicals. We have zero dirty power. 100% of our power comes from clean electricity. We have had zero accidents for two years and seven months. Five zeros. At the bottom, a picture is a thousand words. You see the before and after of our waste tailings piles, which are basically the rocks removed from the pits. Rocks, very stable, geotechnically stable.

Speaker #3: It's basically stacked-up rock, fully geotechnically stable. And we went through the sustainability initiative of actually planting the rock into a green mountain. So what you see now is essentially the picture below.

Speaker #3: We are 100% sustainable. We produce the quintuple zero lithium. We have zero tailings dams. We use zero drinking water. We use zero hazardous chemicals.

Speaker #3: We have zero dirty power; 100% of our power comes from clean electricity. We have had zero accidents for two years and seven months—five zeros.

Speaker #3: At the bottom, a picture is a thousand words. You see the before and after of our waste tailing piles, which are basically the rocks removed from the pits.

Speaker #3: Rocks. Very stable. Geotechnically stable. But more so, we have planted the face of those rocks with artificial germination. We basically did what we call proactive regeneration.

Ana Cabral: More so, we have planted the face of those rocks with artificial germination. We basically did what we call proactive regeneration, and the picture shows how it looks like now, just a year after those piles were created. Geotechnically safe, sustainable, blended into the landscape, which further enhance the environment. We have built the fifth largest industrial mineral lithium producing complex in the world. In the picture you can see that we have a state-of-the-art industrial plant integrated into a mine. The plant is not just an industrial plant. It's a state-of-the-art clean technology lithium processing facility, where we achieve 70% recovery of the lithium, which is among the highest in the sector, and it compares with processing methods which are a lot less sustainable. Sigma is the economic engine for developing the Vale do Jequitinhonha. We lifted the Vale towards prosperity.

Speaker #3: And the picture shows how it looks like now, just a year after those piles were created. So, geotechnically safe, sustainable, blended into the landscape.

Speaker #3: Which further enhance the environment. We have built the fifth largest industrial mineral lithium-producing complex in the world. So in the picture, you can see that we have a state-of-the-art industrial plant integrated into a mine.

Speaker #3: But the plant is not just an industrial plant. It's a state-of-the-art clean technology lithium processing facility, where we achieve 70% recovery of the lithium.

Speaker #3: Which is amongst the highest in the sector in comparison with processing methods, which are a lot less.

Speaker #1: Sustainable . Sigma is the economic engine for the developing the valley of the Q3 We lifted the valley towards prosperity . That is a key reason of minerals , which is the second richest state in the Republic .

Ana Cabral: That is a key region of Minas Gerais, which is the second richest state in the republic. We created 1,000 jobs, 11,000 indirect jobs, and 21,000 beneficiaries from our social programs of microcredit and small scale agriculture. We also have granted drinking water access to 18,000 people. 85% of our workforce is regional. 50% of the economically active population has benefited from our social programs. We have renovated, created, and built schools that put over 500 children in after-schools or school programs. We have been instrumental in delivering 6.8% of GDP growth for the whole state of Minas Gerais. Still, every year we serve 3 million meals so that the new waves of people keep coming to help build this Lithium Valley. We have a built to last company. It's a resilient business that's been thriving throughout lithium cycles.

Speaker #1: We created a thousand jobs 11,000 indirect jobs and 21,000 beneficiaries from our social programs of microcredit and small scale agriculture We also have granted drinking water access to 18,000 people , 85% of our workforce is regional , 50% of the economically active population has benefited from our social programs We have renovated , created and built schools that put over 500 children in after schools or school programs We have been instrumental in delivering 6.8% of GDP growth for the whole state of Minas Gerais , and still , every year we serve 3 million meals .

Speaker #1: So that the new waves of people keep coming to help build this Lithium Valley, so we have a built-to-last company. It's a resilient business that's been thriving throughout lithium cycles.

Ana Cabral: That's what we have achieved in 2025, and that's what we will continue to deliver in 2026. Large scale, low production costs, and traceability. We have had zero accidents for 2.7 years. We uphold the highest health and safety standards in the world, top-ranking amongst all companies in metals and mining. More importantly, we have demonstrated speed of execution, low CapEx to build and to restructure operations such as will be done with mining. We are in a low-cost operating country which supports us to achieve all of that. Now I'm gonna go through the operational financial highlights of 2025, and I'm gonna give you a preview of the Q1 2026 estimated. We have had unparalleled resilience throughout the last year to date. We have generated cash flows across 2025 lithium volatility.

Speaker #1: That's what we have achieved in 2025, and that's what we will continue to deliver in 2026: large scale, low production costs, and traceability. We have had zero accidents for 2.7 years.

Speaker #1: We uphold the highest health and safety standards in the world , top ranking amongst all companies in metals and mining , but more importantly , we have demonstrated speed of execution , low CapEx to build and to restructure operations such as will be done with mining .

Speaker #1: And we are in a low-cost operating country, which supports us to achieve all of that. So now I'm going to go through the operational and financial highlights of 2025.

Speaker #1: And I'm going to give you a preview of the first quarter 2026. Estimated, we have had unparalleled resilience throughout the last year to date.

Speaker #1: We have generated cash flows across 2025 lithium volatility. Our business was built to last and to endure the cycles, for key examples. We signed $146 million in offtake agreements with very robust intrinsic values. Intrinsic value is the advancement we receive from clients for the right to have deliveries of tonnage throughout periods.

Ana Cabral: Our business was built to last and to endure the cycles. Four key examples. We signed $146 million in offtake agreements with very robust intrinsic values. Intrinsic value is the advancement we receive from clients for the right to have deliveries of tonnage throughout periods. First offtake agreement was basically to fund working capital. It was signed in 2025 for deliveries throughout 2026. The total is $96 million for 70,000 tons of deliveries. The second was a $50 million typical offtake prepayment that was signed for 40,000 tons of annual deliveries throughout the next three years, commencing in 2026. Second, we have been the demonstrators that a commercial strategy well executed can actually yield actual results even in this market, even throughout volatility.

Speaker #1: First off, the take agreement was basically to fund working capital. It was signed in '25 for deliveries throughout 2026. The total is $96 million for 70,000 tons of deliveries.

Speaker #1: The second was a $50 million typical off-take prepayment that was signed for 40,000 tons of annual deliveries throughout the next three years, commencing in 2026.

Speaker #1: Second , we have been the demonstrators that a commercial strategy well executed , can actually yield actual results even in this market , even throughout volatility , we have been tracking seasonality and we have achieved $67 million in net sales in the fourth quarter of 25 .

Ana Cabral: We have been tracking seasonality, and we have achieved $67 million in net sales in Q4 2025 and in Q1 2026, solely as a result of this sound commercial policy. First, we monetize lithium seasonality to a T, by basically receiving price adjustments in the fourth quarter, working with our clients to time the deliveries and the final sales, resales of their products throughout the contract season of 2025. That has resulted in the revenues for the fourth quarter. More importantly, we have generated cash flow from a whole new line of business, which is selling the lithium fines, high purity lithium oxide fines that we have reprocessed through our industrial plant, out of our dry stack tailings. That initiated in 2025 and then throughout 2026. We've leveraged our balance sheet and we repaid debt.

Speaker #1: And in the first quarter of '26, solely as a result, as this sound commercial policy. First, we monetize lithium seasonality to a T by basically receiving price adjustments in the fourth quarter.

Speaker #1: Working with our clients to time the deliveries and the final sales resales of their products throughout the contract season of 2025. That has resulted in the revenues for the fourth quarter.

Speaker #1: More importantly , we have generated cash flow from a whole new line of business , which is selling the lithium finds high purity lithium oxide , finds that we have reprocessed through our industrial plant out of our dry stack tailings .

Speaker #1: That happened , initiated in 2025 . And then throughout 2026 with the leverage , our balance sheet . And we repaid that . That was our third highlight , 60% of our short term debt has been repaid , 35% of our total debt has been repaid in a year such as 2025 , on top of that , number , four , we have upgraded and restructured our mining operations completely for safety .

Ana Cabral: That was our third highlight. 60% of our short-term debt has been repaid. 35% of our total debt has been repaid in a year such as 2025. On top of that, number four, we have upgraded and restructured our mining operations completely for safety, for efficiency, for low cost, for cadence, and for better delivery. We transitioned from an outside contractor to full operational control, and we are poised to demonstrate those efficiency gains and cost optimizations throughout the next quarters. Here are pictures that again, 1,000 words. It just shows the lithium fines piles being moved across to the shipping halls already at the port. The result of those sales have actually monetized what we used to call green premium, which doesn't really exist.

Speaker #1: For efficiency , for low cost , for cadence , and for better delivery . We transitioned from an outside contractor to full operational control , and we are poised to demonstrate those efficiency gains and cost optimizations throughout the next quarter's Here are pictures that , again , a thousand words .

Speaker #1: It just shows the lithium fine piles being moved across to the shipping holds, already at the port. The result of those sales has actually monetized what we used to call the green premium, which doesn't really exist.

Ana Cabral: The fact that we actually created this new line of products out of the dry stack tailings definitely delivered to our investors what we call a sustainability premium, meaning actual financial results from the investment we've made on a dry stack unit for the Greentech plant. This is a page with our offtake agreements. The offtake agreements single-handedly enabled our mining upgrade, our long-term debt repayment, and the capacity expansions. We have an announcement. We signed a 40,000-ton-a-year term offtake agreement that's going to net us $50 million in a true prepayment to be closed within the next three months. That amount is equivalent to 120,000 tons to be delivered over the next three years. The use of proceeds will be for our growth strategy.

Speaker #1: But the fact that we actually created this new line of product out of the dry stack tailings definitely delivers to our investors what we call a sustainability premium, meaning actual financial results from the investment we've made on a dry stack unit for the clean tech plant.

Speaker #1: This is a page with our offtake agreements . The Arctic agreements single handedly enabled our mining upgrade . Our loan debt , debt repayment , and the capacity expansions .

Speaker #1: We have an announcement . We signed a 40,000 tonne a year typical offtake agreement that is going to net us $50 million in a true prepayment to be closed within the next three months .

Speaker #1: That amount is equivalent to 120,000 tonnes to be delivered over the next three years. The user proceeds will be for our growth strategy.

Ana Cabral: We also announced and signed the 75,000-ton one-year offtake agreement for a total of $96 million. That offtake agreement is for deliveries throughout 2026, and the purpose of it is for working capital. That's the working capital that enabled the mining upgrade and some of the debt repayments. Now, in 2026, we have two more offtakes to conclude. First, we're going to amend our contract for the equipment leases of the mining upgrade large scale machines that have been backed by an offtake for three years. Initially, it was for 11,000 tons. The number probably will increase depending on the scale of machinery that we are able to secure in Q2. Again, the continuity of the mining upgrade to better, more efficient, more cost efficient, and safer operations.

Speaker #1: We also announced and signed a the 70,500 tonne , one year offtake agreement for a total of $96 million . That offtake agreement is for deliveries throughout 2026 , and the purpose of it is for working capital .

Speaker #1: That's the working capital that enabled the mining upgrade and some of the debt repayments. Now, in 2026, we have two more offtakes to conclude.

Speaker #1: First, we're going to amend our contract for the equipment leases of the mining upgrade. Large scale machines that have been backed by an off day for three years.

Speaker #1: Initially, it was for 11,000 tons. The number probably will increase depending on the scale of machinery that we are able to secure in the second quarter.

Speaker #1: So again , the continuity of the mining upgrade to better , more efficient , more cost efficient and safer operation . The second update that we're about to close is the 80,000 tonne , a year for three years .

Ana Cabral: The second offtake that we're about to close is the 80,000 tons a year for 3 years that is going to net us $100 million in a typical prepayment. That conventional offtake will use proceeds to pay down the long-term debt that currently is sitting on our balance sheet as short-term debt because it matures in December 2026. That was a four-year shareholder debt that has been gracefully given us by our shareholders in late 2022 to enable us to have working capital to commission our plant. That debt will be replaced by an offtake, which is a very sound and very logical operational move for Sigma.

Speaker #1: That is going to net us $100 million in a typical prepayment that conventional offtake will have user proceeds to pay down the long-term debt that currently is sitting on our balance sheet.

Speaker #1: As short-term debt, because it matures in December of 2026, that was a full-year shareholder debt that has been graciously given to us by our shareholders.

Speaker #1: In late 2022, to enable us to have working capital to commission our plant, so that that will be replaced by an off, which is a very sound and very logical operational move for Sigma. On this page, we again demonstrate how the competitive advantage of low costs creates a resilience from the price pressures that lithium has undergone.

Ana Cabral: On this page, we again demonstrate how the competitive advantage of low costs create the resilience from the price pressures that lithium has undergone this year, especially coming from new regions, sometimes not necessarily compliant or traceable product, but more importantly, from the constant refining innovation that the main markets have demonstrated by bringing the ceiling of this industry constantly lower. The ceiling, for instance, lepidolite that once was $25,000 per ton is now around $17,000 to $18,000 per ton, but going lower to a target of probably $15,000 per ton. It doesn't matter. Irrespective, we are actually working below the floor of the industry, which is product coming from the African new supply regions.

Speaker #1: This year , especially coming from new regions . Sometimes not necessarily compliant or traceable product , but more importantly , from the constant refining innovation that the main markets have demonstrated by bringing the ceiling of the industry constantly lower .

Speaker #1: The ceiling for , for instance , lepidolite that once was $2,025 , a 2020 $5,000 per tonne is now around 17 to $18,000 per tonne .

Speaker #1: But going lower to a target of probably $15,000 per tonne. It doesn't matter; irrespectively, we are actually working below the floor of the industry, which is product coming from the African new supply regions.

Ana Cabral: So long as we are sitting exactly where we are in the cost curve, we have the resilience of operations that allow us to, for instance, sign offtakes without floors and continue to deliver excess returns every time prices are in the current levels. On the left, we demonstrate the resilience with our total cash costs, which are all-in sustaining cost plus interest. On the left in green, we show the full year achieved, all-in sustaining costs plus interest and the guidance. We're pretty much in the same ballpark. As a result, we felt comfortable to put in the guidance of $532 for all-in sustaining costs, plus $60 for interest for 2026.

Speaker #1: So , so long as we are sitting exactly where we are in the cost curve , we have the resilience of operations that allow us to , for instance , sign off without flaws and continue to deliver excess returns every time price are in the current levels on the left .

Speaker #1: We demonstrate the resilience with our total cash costs , which are all in sustaining costs plus interest on the left . In green , we show the full year achieved all in sustaining costs plus interest and the guidance .

Speaker #1: So we're pretty much in the same ballpark, and as a result, we felt comfortable to put in the guidance of $532 for all-in sustaining costs, plus $60 for entrance interest for 2026.

Ana Cabral: In the next slide, we show the numbers of how we're able to bring our people safe to their families every single day after day. This is what we work for. We have never had a fatality in 13 years of operations. We have been producing for almost 3 years. We have never had a fatality. More importantly, we're getting to almost 2.7 years with zero accidents with lost time. Our people go home every day and come back to work the following day. That is the highest operational global safety standard in the entire battery materials industry. More so, we sit at the top of the ranking across all metals and mining companies. We have had 1,600 employees here. We now have 1,000 employees. It's a large operation, and we still achieve that.

Speaker #1: In the next slide , we show the numbers of how we're able to bring our people safe to their families . Every single day , day after day .

Speaker #1: And this is what we work for. We have never had a fatality in 13 years of operations. We have been producing for almost three years.

Speaker #1: We have never had a fatality, but more importantly, we're getting to almost 2.7 years with zero accidents with lost time.

Speaker #1: So our people go home every day and come back to work the following day. That is the highest operational global safety standard in the entire battery materials industry.

Speaker #1: But more so, we sit at the top of the ranking across all metals and mining companies. We have had 1,600 employees here.

Speaker #1: We now have 1000 employees . Is a large operation , and we still achieve that 966 days consecutively without accidents . We're very , very proud of it So here is to the numeric operational excellence , a number is a thousand words .

Ana Cabral: 966 days consecutively without accidents. We're very, very proud of it. Here is to the numeric operational excellence. A number is a thousand words. The unique resilience and robust cash flows can be demonstrated with each and every one of the main items of our 2025 and Q1 2026 estimated operational performance. First, offtakes. We had signed a $96 million offtake prepayment in 2025 that enable us to receive working capital by having our production paid in advance. We just signed a $50 million traditional offtake for 3 years of 40,000 ton deliveries, totaling 120,000 tons to be delivered over the next 3 years. In advance, up until June this year, we're going to receive $50 million. Traditional typical offtake.

Speaker #1: The unique resilience and robust cash flows can be demonstrated by each and every one of the main items of our 2025 and first quarter.

Speaker #1: 26 estimated operational performance . First off , takes . We had signed a 96 million offtake repayment in 25 that enable us to receive working capital by having our production paid in advance , then we just signed a 50 million traditional offtake for three years of 40,000 tonne deliveries , totaling 120,000 tonnes to be delivered over the next three years .

Speaker #1: But in advance , up until June this year , we're going to receive $50 million . Traditional , typical offtake Irrespectively . We have managed to repay debt to a magnitude that is significant considering the volatility in low points .

Ana Cabral: Irrespective, we have managed to repay debt to a magnitude that is significant considering the volatility in low points lithium prices reached in 2025. We paid 60% of our short-term debt and 35% of our total debt. That was basically because of cash flow generation. This company was built for cash flow generation. We are a cash machine. In Q4 2025, we generated $31 million of cash from operations. In Q3 2025, the previous quarter, we generated $23 million. We increased our cash flow generation by 35% from Q3 to Q4 2025. More importantly, the lithium materials production has had a decrease in volumes because of the full restructure we conducted in mining. Given that we are an industrial operation, we delivered another source of revenues.

Speaker #1: Lithium prices reached in 2025. We paid 60% of our short-term debt and 35% of our total debt. That was basically because of cash flow generation.

Speaker #1: This company was built for cash flow generation. We are a cash machine. In the fourth quarter of '25, we generated $31 million of cash from operations. In the third quarter of '35, ...

Speaker #1: In the previous quarter, we generated $23 million. So, if we increased our cash flow generation by 35% from the third quarter to the fourth quarter of 2025, more importantly, the ledger materials production has had decreasing volumes because of the full restructure we conducted in mining.

Speaker #1: But given that we are in industrial operation , we delivered another source of revenues . In fact , we built another business which was reprocessing the dry stack tailings into what we call a low grade lithium fines .

Ana Cabral: In fact, we built another business which was reprocessing the dry stack tailings into what we call low-grade lithium fines. Ultimately, we had equivalent of 70,000 tons of the main high-grade product in revenues sitting as inventory accumulated throughout the last years. That material became this new line of business of what we call high purity lithium fines. For the full year of 2025, we produced 183,000 tons of high-grade premium lithium oxide. For the full year of 2024, we produced 240,000 tons of high-grade premium lithium oxide. Our annual production decreased in 24%. However, how did we generate so much cash flow? How did we accomplish so much repaying debt? By basically creating a new line of business, which is what we call the sustainability monetization, the green premium in numbers.

Speaker #1: So ultimately, we had the equivalent of 70,000 tons of the main high-grade product in revenues sitting as inventory, accumulated throughout the last years.

Speaker #1: And that material became this new line of business of what we call high purity lithium fines. So for the full year of 2025, we produced 183,000 tons of high grade premium lithium oxide. For the full year of 2024, we produced 240,000 tons of high grade premium lithium oxide.

Speaker #1: So our annual production decreased in 24% . However , how did we generate so much cash flow ? How did we accomplish so much repaying that by basically creating a new line of business , which is what we call the sustainability monetization .

Ana Cabral: We reprocessed the lithium contained in our lithium fines in our dry stack piles, and we created a whole new business, which is selling high purity lithium fines, which have a lower grade, but in monetary value, it's equivalent to 70,000 tons of the high-grade premium lithium oxide. All in all, we're not even solving for volumes, we're solving for cash flow, and cash flows were delivered and debt was repaid. Here are the numbers which speak for a thousand words and do not have an opinion. Numbers are numbers. What we wanna show on this slide is again, the quantification and a pictorial of how commercially successful strategy actually helped us to deliver revenues in Q3 2025 and in Q4 2025. We have fantastic clients who are commercial partners, so we sell them the material.

Speaker #1: The green premium in numbers . We reprocessed the lithium contained in our lithium fines in our dry stack , and we created a whole new business , which is selling high purity lithium fines , which have a lower grade .

Speaker #1: But in monetary value, it's equivalent to 70,000 tons of the high-grade premium lithium oxide. So all in all, we're not even solving for volumes.

Speaker #1: We're solving for cash flow. And cash flows were delivered. And that was repaid in—here are the numbers, which speak for a thousand words.

Speaker #1: And do not have an opinion. Numbers are numbers. What we want to show on this slide is, again, the quantification and a pictorial of how a commercially successful strategy actually helped us to deliver revenues in the third quarter of '25.

Speaker #1: And in the fourth quarter of '25, we have fantastic clients who are commercial partners. So we sell them the material. We do a final sale, and they take the risk that the sale takes place using a provisional price.

Ana Cabral: We do a final sale, and they take the risk. That sale takes place using a provisional price. We take some of the risk, but we also gain some of the upside. In other words, when our clients resell their product, resell to their clients, we have a profit sharing gain or a profit sharing loss. Last year we had a loss. This year we had a substantial gain. Again, this was achieved by mapping seasonality, and seasonality in this industry is pretty clear. It happens in the restocking period that takes place after September. It's called contract season. Our commercial partners worked with us to basically execute their final resales mostly after October 2025, which allowed us to reap the benefits of a much better pricing environment than what was experienced throughout the whole year because of the tariff volatility in the metals market.

Speaker #1: So we take some of the risk , but we also gain some of the upside . In other words , when our clients resell their product , resell to their clients , we have a profit sharing gain or a profit sharing loss .

Speaker #1: Last year , we had a loss . This year we had a substantial gain . Again , this was achieved by mapping seasonality and seasonality in this industry is pretty clear .

Speaker #1: It happens in the restocking period that takes place after September . It's called contract season . So our commercial partners worked with us to basically execute their final resales , mostly after October of 2025 , which allowed us to reap the benefits of a much better pricing environment than what was experienced throughout the whole year .

Speaker #1: Because of the tariff volatility in the metals market, so when you look at the greens, you can see the resales by our clients.

Ana Cabral: When you look at the greens, you can see the resales by our clients. When you look at the red, you can see the sales from Sigma to the client. You look at the line, you see the lithium prices and the tremendous volatility that happened throughout the year. In partnership with our clients, we captured not only the first peak of volatility, which happened in August, but also the subsequent curve of price increases that happened throughout contract season beginning in October 2025. That helped us book over $20 million in final price adjustments in Q3 2025, and it helped us book over $14 million in final price adjustments in Q4 2025. These are substantial revenues, so that's a quantification of what a sound commercial strategy is.

Speaker #1: When you look at the red , you can see the sales from sigma to the client and you look at the line , you see the lithium prices in the tremendous volatility that happened throughout the year in partnership with our clients , we captured not only the first peak of volatility , which happened in August , but also the subsequent curve of price increases that happened throughout contract season beginning in October 2025 .

Speaker #1: That helped us book over $20 million in final price adjustments in the third quarter of 2025. And he helped us book over $14 million in final price adjustments in the fourth quarter of 2025.

Speaker #1: These are substantial revenues, so that's a quantification of what a sound commercial strategy is. On this slide, I'll go very slowly because we have quite a lot of information to unpack.

Ana Cabral: On this slide, I'll go very slowly because we have quite a lot of information to unpack. Again, it's the financial discipline that generated these high operating cash margins. High operating cash margins are the source of the cash flow we posted. In 2025, if you compare Q4 of 2024 with Q4 of 2025, we have substantially increased our operating cash margin. If you compare the full year, 2024 full year and 2025 full year, our gross margins have decreased. Yes, because the pricing environment in 2025 was very challenging. What is interesting is that the cash margins and the cash flow generation came from one thing and one thing only. We were able to reduce our costs faster than the decrease in our revenues.

Speaker #1: But again, it's the financial discipline that generated these high operating cash margins. High operating cash margins are the source of the cash flow.

Speaker #1: We posted in 2025. If you compare the fourth quarter of '24 with the fourth quarter of '25, we have substantially increased our operating cash margin.

Speaker #1: If you compare the full year 2024 , full year and 2025 full year are gross margins have decreased . Yes , because the pricing environment in 25 was very challenging .

Speaker #1: But what is interesting is that the cash margins and the cash flow generation came from one thing, and one thing only. We were able to reduce our costs faster than the decrease in our revenues.

Ana Cabral: Despite the mining restructuring, despite price volatility, we were focused on what we could control and what we can control and on what we always control, which are our costs. If you look at the bottom of the page, you can see that the quarterly comparison between Q4 2024 and Q4 2025 shows a 77% reduction in costs. That's way more than just variable costs. When you look at the annual cost reduction, you can see that full year 2024 to full year 2025, we've had a 21% decrease in costs. When we talk about these operating costs, we add operating costs, SG&A, ESG, plus all others. It's truly an achievement of financial discipline. We're always cutting what we control. We're always optimizing costs. With that, we can go back to revenues.

Speaker #1: So despite the mining restructuring , despite price volatility , we were focused on what we could control and what we can control . And on what we always control , which are our costs So if you look at the bottom of the page , you can see that the quarterly comparison between fourth quarter 24 and fourth quarter 25 shown as 77% reduction in costs , that's way more than just variable costs .

Speaker #1: When you look at the annual cost reduction, you can see that from full year '24 to full year '25, we've had a 21% decrease in costs.

Speaker #1: So, when we talk about these operating costs, we add operating costs as an ESG plus, all others. So, it's truly an achievement of financial discipline.

Speaker #1: We're always cutting what we control . We're always optimizing costs . So with that , we can go back to revenues . In other words , when you look at net sales revenues on a quarterly basis , we've had fluctuations which again , just demonstrate how volatile lithium prices were .

Ana Cabral: In other words, when you look at net sales revenues on a quarterly basis, we've had fluctuations, which again, just demonstrate how volatile lithium prices were. More notably, from Q3 to Q4, when we restructured mining operations, we had a 41% decrease in net sales revenues. However, when we look at the Q1 2026 estimate, we more than compensated for that decrease. Why is that? Because we not only opened this new line of lithium fines, which were the low-grade high-purity business that we created out of our dry stack tailings, but also all the work we've done in mine restructuring began to show results. On an annual basis, the revenues decreased 27%. When you look at the bigger picture here, what is actually visible that yes, revenues decreased 27% on an annual basis.

Speaker #1: More notably, from the third quarter to the fourth quarter, when we restructured mining operations, we had a 41% decrease in net sales revenues.

Speaker #1: However , when we look at the first quarter of 2026 , estimate , we more than compensated for that decrease . Why is that ?

Speaker #1: Because we not only opened this new line of lithium fines, which were the low grade, high purity business that we created out of our dry stack tailings, but also all the work we've done with mine.

Speaker #1: Restructuring began to show results . So on an annual basis , the revenues decreased 27% . And so when you look at the bigger picture here , what is actually visible that yes , revenues decreased 27% on an annual basis .

Ana Cabral: Cost decreased 21% on an annual basis. Cost decreased less than revenues on an annual basis. We were very quick to compensate that and to fix it in Q4, where we cut costs and we decreased costs by 77%. This is how financial discipline is demonstrated with numbers. In this slide, we show the quantification of the financial discipline, but now on balance sheet optimization. We have significantly deleveraged despite all the price volatility, despite all that's happened with revenues. From Q4 2024 to Q4 2025, we lowered our short-term debt by 60%. From Q4 2024 to the estimate of Q1 2026, which is actually the numbers that we have closing, we lowered it by 68%. The work continued. We didn't stop.

Speaker #1: Costs decreased 21% on an annual basis. So, gross costs decreased less than revenues on an annual basis. But we were very quick to compensate that and to fix it in the fourth quarter, where we cut costs and we decreased costs by 77%.

Speaker #1: So this is how financial discipline is demonstrated with numbers in this slide , we show the quantification of the financial discipline . But now on balance sheet optimization , we have significantly deleveraged despite all the price volatility , despite all that's happened with revenues from fourth quarter 24 to the fourth quarter , 25 , we lower our short term debt in 60% from the fourth quarter .

Speaker #1: Twenty-four to the estimate of first quarter '26, which is actually the numbers that we have closing. We lowered it by 68%.

Ana Cabral: When you look at Q3 2025 against current, we lowered the debt by 49%. That's a complete restructuring the way we fund ourselves, in the short term, in the way we look at working capital even. Meaning, clients are now funding our operation because of our successful commercial partnerships with our clients. We make it win-win so that it costs us less in working capital, and we de-leverage our balance sheet. This slide, I'll go very slowly on it because it shows our cash flow generation outlook. It's quite simple. It's quite straightforward. Again, it just demonstrates how Sigma is a cash machine. Why? Because we have high margins. We're built for cash flow generation. We have estimated that in the next 12-month period for phase one, we're gonna probably have 240,000 tons of production.

Speaker #1: So the work continued . We didn't stop then . When you look at the third quarter , 25 against current , we lowered the debt in 49% .

Speaker #1: That's a complete restructuring . The way we found ourselves in a short term , in a way , we look at working capital , even meaning clients are now funding our operation because of our successful commercial partnerships with our clients .

Speaker #1: We make it win win . So that it costs us less in working capital . And with the leverage our balance sheet , this slide , I'll go very slowly on it because it shows our cash flow generation outlook .

Speaker #1: It's quite simple . It's quite straightforward . And again , it just demonstrates how sigma is a cash machine . Why ? Because we have high margins .

Speaker #1: We're built for cash flow generation. We have estimated that, in the next 12-month period for Phase One, we're going to probably have 240,000 tons of production.

Ana Cabral: As we've shown before, for the year, we're going to deliver 200,000 tons. Now, because of our optimum cost efficiencies, we are going to be yielding an all-in sustaining cost, including interest of $592. That's our estimation for the next twelve months, as we've shown you in guidance. That creates cash flows no matter what. If lithium retrocedes to $1,500 a ton, we're gonna be generating about $158 million in free cash flow after interest, free cash flow. If lithium stays around where it is now, between $1,800 and $2,000 a ton, we can generate anything between $218 to $260 million of free cash flow, just with one phase.

Speaker #1: As we've shown before , for the year , we're going to deliver 200,000 tons . Now because of our optimum cost efficiencies , we are going to be yielding an all in sustaining cost , including interest of $592 .

Speaker #1: That's our estimation for the next 12 months. As we've shown you in guidance, that creates cash flows no matter what. If...

Speaker #1: Lithium regret retro to $1,500 a ton , we're going to be generating about $158 million in free cash flow after interest free , free cash flow .

Speaker #1: If lithium stays around where it is now, between $1,000 and $802,000 a ton, we can generate anything between $218 million to $260 million of free cash flow, just with one phase. As we double capacity, which will be in place by the end of next year, that number increases.

Ana Cabral: As we double capacity, which will be in place by the end of next year, and we prorate production as we commission, you can sharpen your pencils, and you can do the math of how much cash flow we're going to have with two plants. More importantly, as we calculate all-in sustaining costs and all-in cash costs, the only optimization we've done were on G&A and ESG. You don't need two of me or two of most of our personnel to run these businesses on the administrative side. Interest, because we're gonna cut interest in half, given that the interest is on the total debt, that we are going to contract precisely to build plant two. We have not factored in the actual operational scale gains that come from running two plants using our infrastructure that is built and utilized now for one plant.

Speaker #1: Capacity . And we prorate production as we commission . You can sharpen your pencils and you can do the math of how much cash flow we're going to have with two plants , more importantly , as we calculate all in sustaining costs and all in cash costs , the only optimization we've done were on G&A and ESG .

Speaker #1: You don't need two of me or two of most of our personnel to run these businesses on the administrative side and interest, because we're going to cut interest in half.

Speaker #1: Given that the interest is on the total debt that we are going to contract precisely to build Plant Two. So we have not factored in the actual operational scale gains that come from running two plants using infrastructure that is built and utilized.

Ana Cabral: The infrastructure sharing of two plants are probably going to bring more cost gains, which are not here in these cash flows. Just with this conservative analysis of doubling operations and having some synergies on G&A and interest, we're bound to generate basically $600 million in free cash flow if prices stay where they are. If prices retrocede to about 1,500, that's okay too. We'll generate $384 million in free cash flow, meaning after interest, at those levels. What becomes really interesting is when we build a third line, which could be done concomitant with the second line. That means that at 770,000 tons of production, and again, we're just calculating efficiencies here on G&A, ESG, and interest. We flattened the interest. We haven't cut interest further.

Speaker #1: Now for one plant . So the infrastructure sharing of two plants are probably going to bring more cost gains , which are not here in this cash flows , but just with this conservative analysis of doubling operations and having some synergies on G h and interests , we're bound to generate basically $600 million in free cash flow .

Speaker #1: If stay where they are , if prices retrocede to about 1500 , that's okay too . We'll generate $384 million in free cash flow , meaning after interest at those levels , what becomes really interesting is when we build a third line , which could be done concomitant with the second line .

Speaker #1: That means that at 770,000 tons of production and again , we're just calculating efficiencies year on G and a ESG and interest . And we flattened the interest .

Ana Cabral: We just cut G&A further because again, to be a commercial person or to be an administrative person, you don't need to triple your numbers when you have triple plants. Interest is flat, but G&A and ESG was the only number that was reduced. What does that mean? Our all-in cash sustaining cost, including interest, goes down to $495 per ton with three lines. If prices retrocede to $1,500 by the end of 2028, when we plan to have this capacity in place, we could be generating $581 million in free cash flow. If the prices stay where they are, we could be generating $900 million in free cash flow.

Speaker #1: We haven't cut interest further. We just cut it further because, again, to be a commercial person or to be an administrative person, you don't need to triple your numbers when you have triple plants.

Speaker #1: So interest is flat , but G and A and ESG was the only number that was reduced . What does that mean ? Our all in cash sustaining costs , including interest , goes down to $495 per ton with three lines .

Speaker #1: So if prices retrocede to a $1,500 by the end of 28 , when we plan to have this capacity in place , we could be generating $581 million in free cash flow if the prices stay where they are , we could be generating $900 million in free cash flow .

Ana Cabral: That's a significant amount, and it just shows how building long-term value means building a company that is geared to generate operating efficiency, operational excellence, and quite a lot of free cash flow to shareholders. As management operators, our interests are 100% aligned. We're building a business to last. We're building a business to create shareholder value for all of us, management and outside shareholders. This slide shows the cash flow bridge, the cash bridge with its respective explanation. Again, more numeric demonstration that the disciplined execution that we have delivered in 2025 and continue to deliver throughout 2026 has created this operational resilience despite the very volatile market conditions. We have had operating cash generation. This is why we didn't raise capital, because we were able to generate the amount of cash to deliver and to execute on plan, on target.

Speaker #1: That's a significant amount , and it just shows how building long term value means building a company that is geared to generate operating efficiency , operational excellence , and quite a lot of free cash flow to shareholders as management operators are interests are 100% aligned .

Speaker #1: We're building a business to last. We're building a business to create shareholder value for all of us—management and outside shareholders.

Speaker #1: So this slide shows the cash flow bridge , the cash bridge with its respective explanation . So again , more numeric demonstration that the discipline execution that we have delivered in 25 and continue to deliver throughout 26 has created this operational resilient despite the very volatile market conditions we have had operating cash generation .

Speaker #1: This is why we didn't raise capital, because we were able to generate the amount of cash to deliver and to execute on plan, on target.

Ana Cabral: Let's start at the end of Q3 2025. We had $6 million in cash. As forecasted and as discussed in those materials, and I encourage you to go back to them, we continued on the trend to deliver cash flow from operations. On a net basis, we delivered $31 million in cash from operations. Mainly final price adjustments from transactions from sales that had taken place on a provisional price basis, as we discussed earlier. We had our cash operating costs. We have executed CapEx towards the mining upgrade, and we had $26 million of debt repayment and interest repayment, as we've shown in number one and number two. Debt repayment was just debt repayment, amortization of principal.

Speaker #1: So, let's start at the end of the third quarter of '25. We had $6 million in cash, as forecasted, and as discussed in those materials.

Speaker #1: And I encourage you to go back to them . We continued on the trend to deliver cash flow from operations . So on a net basis , we delivered $31 million in cash from operations , mainly final price adjustments from transactions , from sales that had taken place on a basis .

Speaker #1: As we discussed earlier, then we had our cash operating costs. We have executed CapEx towards the mining upgrade, and we had $26 million of debt repayment and interest repayment.

Speaker #1: As we've shown in number one . And number two , that repayment was just that that repayment amortization of principal interest expense was the annual cash expense for the $100 million of long term debt .

Ana Cabral: Interest expense was the annual cash expense for the $100 million of long-term debt we've had in our balance sheet. We had a flat cash position between Q3 2025 and Q4 2025. This is financial discipline. We conserved cash. We burned 0 cash. With the knowledge that there was a whole new business of lithium fines coming on stream, which again, we flagged during our third quarter presentation, we had inflows in Q1 2026, which were the cash sales of those lithium fines that we affected and closed on the beginning of the year. We achieved $30 million on the sales of the lithium fines, and we achieved $5 million on the sales of the premium high grade. That was the beginning of sales resulting from our mining restructuring.

Speaker #1: We've had in our balance sheet. So we had a flat cash position between the third quarter of '25 and the fourth quarter of '25.

Speaker #1: This is financial discipline . We conserve cash . We burned zero cash . So with the knowledge that there was a whole new business of lithium fines coming on stream , which again , we flagged during our third quarter presentation , we had inflows in the first quarter of 26 , which were the cash sales of those lithium fines that we affected and closed on the beginning of the year .

Speaker #1: So we achieved a $30 million on a sales of the lithium fines . And we achieved $5 million on a sales of the premium high grade .

Ana Cabral: We had a $24 million CapEx bill for the mining upgrade, mining restructuring, and all that we had to do. As we conserved cash and as we generated cash from that new line of business, which was reprocessing dry stack tailings, we were able to not only pay our CapEx for mining restructuring and upgrade, but also to continue to do debt principal repayment. We paid down another $5 million in debt, which means we increased our cash position in Q1 2026 by 100%. We doubled the cash position. This is again, numbers. Numbers don't have an opinion, and it's very much in line with the strategy for cash flow discipline that we have laid out in Q3 2025. We're giving you an advancement here or a preview, as we call it.

Speaker #1: That was the beginning of sales resulting from a mining restructuring. Then we had a $24 million CapEx bill for the mining upgrade, mining, restructuring, and all that.

Speaker #1: We had to do . But as we conserve cash and as we generated cash from that new line of business , which was reprocessing dry stack tailings , we were able to not only pay our CapEx for mining restructuring in upgrade , but also to continue to do that .

Speaker #1: Principal repayment. So we paid down another $5 million in debt, which means we increased our cash position in the first quarter of 2026 by 100%.

Speaker #1: So we doubled the cash position . So this is again , numbers . Numbers don't have an opinion . And it's very much in line with the strategy for cash flow discipline that we have laid out in the third quarter of 25 .

Ana Cabral: We have another $14 million of cash sales from the lithium fines business, the reprocessed dry stacking tailings. We have another $50 million of a true long-term off-take agreement prepayment that is poised to close by the end of the second quarter. We have about $32 million of the first installments of the $96 million off-take that we signed just in 2025 for the high-grade premium lithium. Which is the 70,000 tons that we are planning to deliver in 2026. Again, we close Q1 2026 with $12 million in cash, and we have a significant amount of cash coming our way in Q2 2026.

Speaker #1: We're giving you an advancement here, or a preview, as we call it. We have another $14 million of cash sales from the.

Speaker #1: We call lithium fine business . The reprocessed dry stacking tailings . Then we have another $50 million of a true long term . Offtake agreement .

Speaker #1: Pre-payment. That is poised to close by the end of the second quarter. And then we have about $32 million of the first installments of the $96 million offtake that we signed just in 2025 for the high grade premium lithium, which is the 70,000 tons that we are planning to deliver in 2026.

Speaker #1: So again, we close the first quarter of six with $12 million in cash, and we have a significant amount of cash coming our way in the second quarter of '26.

Ana Cabral: Having executed pretty much most of the mining upgrade, as you can see in the CapEx bill for $24 million we paid in Q1 2026, plus the $4 million we initiated in Q4 2025. Now we're gonna do a bit about the operational work we have done to restructure our mining operations. This was done for, again, the construction of long-term value for shareholders. We had to do this. We had to take control of our mine because without that, we would not be ready to deliver the cadence that was necessary to affect the capacity expansions of the second and third industrial plants. Just to recap, we are a fully integrated industrial mining operation. We have this proprietary clean technology that produces what we call the clean tech, the clean lithium.

Speaker #1: Having executed pretty much most of the mining upgrade. As you can see in the CapEx bill for $24 million, we paid in the first quarter of '26, plus the $4 million we initiated in the fourth quarter of 2025.

Speaker #1: Now we're going to do a bit about the operational work we have done to restructure our mining operations . This was done for , again , the construction of long term value for shareholders .

Speaker #1: We had to do this. We had to take control of our mind, because without that, we would not be ready to deliver the cadence that was necessary to affect the capacity expansions of the second and third industrial plants.

Speaker #1: Just to recap, we are fully integrated industrial and mining operations. We have the proprietary clean technology that produces what we call the Clean Tech.

Ana Cabral: That means we have a mine that's integrated into an industrial facility. Again, stopping the mine doesn't mean the industry stops. Obviously, what we want is having a mine at full tilt and then the plant receiving fresh rock. The plant can do many things given that we have dry stack materials. Once we think about doubling capacity and tripling capacity, we mean that our mines need to operate at full tilt and in perfect cadence so that our plant can deliver on the 70% recovery levels it actually has demonstrated it can achieve in the Q4 of 2024. Think of it as a blast furnace. If we turn it on and off, it will not maintain those levels of efficiency.

Speaker #1: The clean lithium . That means we have a mine that's integrated into an industrial facility . And again , stopping the mine doesn't mean the industry stop's obviously what we want is having a meaningful tilt , and then the plant receiving fresh rock .

Speaker #1: But the plant can do many things . Given that we have dry stacked materials , but once we think about doubling capacity and tripling capacity , we mean that our minds need to operate at full tilt and imperfect cadence .

Speaker #1: So that our plant can deliver on the 70% recovery levels. It actually has, as it has demonstrated it can achieve, in the fourth quarter of 2024.

Ana Cabral: If the same amount of material is not fed into that dense media separators per hour, it won't achieve 70% recovery. For that, we need mine planning, mine execution that delivers piles or delivers fresh rock to the ROM pad, on the same quantities regularly, at least on a weekly schedule. This is kind of the overall concept of a 100% vertically integrated operation. Here is a picture of a Greentech plant at night. Unquestionably, a beautiful industrial installation. This is what we've done with the Greentech plant that allow us to get to the 70% recovery. We had a 2.0 version of the plant, which was the version we operated from July 2023 until November 2024. That was now recovering 70%. It was recovering anything between 50, low 60s, almost 60.

Speaker #1: Think of it as a blast furnace. If we turn it on and off, it will not maintain those levels of efficiency.

Speaker #1: So if the same amount of material is not fed into that dense media separators per our , it won't achieve 70% recovery . And for that , we need mind planning , mind execution that delivers piles or delivers fresh rock to the ROM pad on the same quantities regularly , at least on a weekly schedule .

Speaker #1: So this is kind of the overall concept of a 100% vertically integrated operation. Here is a picture of a green tech plant at night.

Speaker #1: Unquestionably, unquestionably a beautiful, beautiful industrial installation. This is what we've done with the Green Tech plan that allows us to get to the 70%.

Speaker #1: Recovery . We had a 2.0 version of the plant , which was the version we operated from July 23rd until December . November 2024 .

Speaker #1: That was not recovering 70%. It was recovering anything between 50, low 60s, almost 60. The dry stack tailing units were not working as we wanted anyway.

Ana Cabral: The dry stack tailings units was not working as we wanted. Anyway, we actually invested a significant amount of CapEx to get the plant to what we call the current stage, which is a 3.0 version that we plan to double and triple, meaning we're building another one of these, and then we're building a second one of these. In order for that to happen, as we said earlier, we need mine and plant to work in cadence. How did we get to the 70% recoveries? We automated industrial operations. We have software, we have SCADA, we have algorithms, we have detection of anomalies automatically. We have correction recommendations automatically. It's self-learning metallurgy, self-learning from mineralogy. It is a bot that basically keeps on getting better and better and better when it's fed the same mineralogy.

Speaker #1: We actually invested a significant amount of CapEx to get the plant to what we call the current stage, which is the 3.0 version that we plan to double and triple, meaning we're building another one of this.

Speaker #1: And then we're building a second one at this. But in order for that to happen, as we said earlier, we need mine and plant to work in cadence.

Speaker #1: How did we get to the 70% recoveries ? We automated industrial operations . We have software , we have we have algorithms , we have detection of anomalies automatically .

Speaker #1: We have correction recommendations automatically. It's a self-learning methodology, self-learning from mineralogy. It is a bot that basically keeps on getting better and better and better.

Ana Cabral: This is a picture of our fully automated control room. We have the mine. The mine had quite a lot of work to be done. It was using less than efficient small equipment. It was using too many pieces of equipment. At one point, there were 48 small 40-ton trucks trafficking through the mine. So a lot had to be done there. First we had to fix geometry. It had to be widened. Here on the picture you already see the result of widening the geometry. We've done intermediary strip with the objective of widening geometry and increase the mine life and increase access and open other areas with ore that were closer to surface. What we've done, we basically open additional mine fronts now to accelerate the ramp up. How did we do this?

Speaker #1: When it's fed the same mineralogy. This is a picture of our fully automated control room. Then we have the mine. The mine had quite a lot of work to be done.

Speaker #1: It was using less efficient , small equipment . It was using too many pieces of equipment . At one point there were 48 small 40 ton trucks trafficking through the mine So a lot had to be done there .

Speaker #1: First , we had to . Fix geometry . It had to be widened . And here on the picture you already see the result of widening the geometry .

Speaker #1: So we've done intermediary strip with the objective of widening geometry and increasing the mine life, and increasing access and opening other areas that were closer to surface.

Ana Cabral: By using larger equipment, larger fleet to remove strip faster. Larger equipment increases efficiency on the excavators, on trucks across the board. In parallel, while we did that, mostly in Q4, the Greentech plant continued to operate. We reprocessed the lithium materials from the dry stack tailings during Q4 2025 and Q1 2026 with superior recovery. Not the 70% recovery, but it enriched it enough to create decent cash flow, to create a decent sale value, a decent value added, so that it could generate the cash flow and the revenues we achieved both in the later Q4, but also throughout Q1. What we're hoping to happen, and we've seen happening already now in March, was that recoveries get closer to 70% as we resume delivering fresh rock to the plant.

Speaker #1: So what we've done , we basically open additional mind fronts now to accelerate the ramp up . How did we do this ? By using larger equipment , larger fleet to remove strip faster .

Speaker #1: So, larger equipment increases efficiency on the excavators, on trucks, across the board in parallel. While we did that mostly in the fourth quarter, the green tech plan continued to operate.

Speaker #1: So we reprocessed the lithium materials from the dry stack tailings during the fourth quarter , 25 and the first quarter of 26 . With superior recovery , not the 70% recovery , but it enriched it enough to create decent cash flow to create a decent sale value , a decent value added so that it could generate the cash flow and the revenues we achieved .

Speaker #1: Both in , in , in the later fourth quarter . But also throughout the first quarter . So what we're hoping to happen , and we've seen happening already now in March was that recoveries get closer to 70% as we resume delivering fresh rock to the plant Now this is how we're going to bring all that software knowledge to the plant .

Ana Cabral: Now this is how we're gonna bring all the software knowledge to the plant. We started and we continue. We have Fast Mining implemented in process for mine planning. We have the same software implemented for fuel control. We have fatigue automatic software detection. We have a cost control app sitting on iPads and iPhones for all the mine operators. We have loading and blasting simulations for optimal results with minimum loads, minimum vibrations. We're bringing the same software technology, the same intelligence to the mining operation, and that is starting in the control room for mining, which is here, as you can see in the picture. This is a picture of the first wave of larger equipment. The equipment is gonna get bigger and bigger. This is the kind of the small large equipment. More important than that, we own production control.

Speaker #1: We started, and we continued. So, we have fast mining implemented in process for mine planning. We have the same software implemented for fuel control.

Speaker #1: We have fatigue, automatic software detection. We have a cost control app sitting on iPads and iPhones for all the mine operators.

Speaker #1: So we have loading and blasting simulations for optimal results with minimal loads . Minimum vibrations . So we're bringing the same software technology , the same intelligence to the mining operation .

Speaker #1: And that is starting in the control room for mining, which is here. As you can see in the picture, this is a picture of the first wave of larger equipment.

Ana Cabral: We drive production control. Mine planning is ours. Blasting control is ours. We hired a third-party driller for blasting. We're managing different contractors with our own in-house mining team. That allows us to gain confidence on deploying larger equipment, on investing larger equipment, and on basically doing the calculated analysis of where we should be blasting for safety, for optimal geometry, but also for efficient ore recovery. Now we're gonna talk about how we're going to continue to expand. We are resuming the construction of plant two this year. We're gonna double industrial capacity for the high-grade premium lithium oxide. We're not that far. In other words, once we get to it, we're gonna go from the 240,000 tons that we're guiding to 520,000 tons. That is not that far away.

Speaker #1: The equipment is going to get bigger and bigger . This is the kind of the small , large equipment . So but more important than that , we own production control .

Speaker #1: We drive production control . Mind planning is ours . Blasting control is ours . We hired a third party driller for blasting , so we're managing different contractors with our own in-house mining team that allows us to gain confidence on deploying larger equipment , on investing in larger equipment and on basically doing the calculated analysis of where should we be blasting for safety , for optimal geometry .

Speaker #1: But also for efficiency or recovery. Now we're going to talk about how we're going to continue to expand. We are resuming the construction of Plant Two.

Speaker #1: This year . So we're going to double industrial capacity for the high grade premium lithium oxide . And we're not that far . In other words , once we get to it , we're going to go from the 240,000 tons that we're guiding to 520,000 tons .

Ana Cabral: More importantly, there's the potential that we may build two and three sequentially. We're never gonna decommission the construction crews. Given that the CapEx involved here is actually very little, and the CapEx efficiency is very high, meaning it's gonna cost us $80 million to conclude the second plant, and it's gonna cost us $100 million to build a third plant. With $180 million, we are able to take our production from 240,000 tons a year to 770,000 tons a year. That's a substantial increase, and that's one of the most efficient CapEx ratios in the whole industry. This demonstrates what can happen when we double and then triple production. We run the fifth-largest industrial mineral complex in the world. We are the largest lithium mineral producer in the Americas.

Speaker #1: And that is not that far away. More importantly, there's the potential that we may build two and three sequentially. So we're never going to decommission the construction crews.

Speaker #1: Given that the CapEx involved here is actually very little, and the CapEx efficiency is very high, meaning it's going to cost us $80 million to conclude the second plant.

Speaker #1: And it's going to cost us $100 million to build a third plant. So with $180 million, we are able to take our production from 240,000 tons a year to 770,000 tons a year.

Speaker #1: That's a substantial increase, and that's one of the most efficient CapEx ratios in the whole industry. So this demonstrates what can happen when we double.

Speaker #1: And then triple production. We run the fifth largest industrial mineral complex in the world. We are the largest lithium mineral producer in the Americas.

Ana Cabral: Here we have all of our peers. We have the lithium producers in the Americas that produce from the lakes in Argentina, and that includes the Chilean and the American producers. We also have the producers from Australia, and we have the producers from Africa. Although we are the fifth-largest industrial mineral complex in the world, and we're the largest industrial mineral producer in the Americas, we are the eighth ranked producer in the world as a whole. Now look what happens when we double and we triple. When we double, we go from number 8 to number 6 or number 5. When we triple, we go to number 4. All of these companies have valuations substantially higher than ours. In fact, we're valued as a non-producing company. The effect of doubling production and tripling production is not just numeric.

Speaker #1: But here we have all of our peers. We have the lithium producers in the Americas that produce from the lakes in Argentina.

Speaker #1: And that includes the Chilean and the American producers. We also have the producers from Australia, and we have the producers from Africa.

Speaker #1: So, although we are the fifth largest industrial mineral complex in the world, and we're the largest industrial mineral producer in the Americas, we are the eighth-ranked producer in the world as a whole.

Speaker #1: Now look what happens when we double, and triple. When we double, we go from number eight to number six or number five.

Speaker #1: Then when we triple , we go to number four . All of these companies have valuations substantially higher than ours . In fact , we're valued as a non-producing company .

Ana Cabral: It's also a clear demonstration that we can be up there in the rankings with a concomitant valuation. That is what it means for us to build long-term shareholder value. This is what we're planning to do. This is the slide that shows how close we are to getting there. We have made a decision in Q4 2024 and in Q1 2025 of accelerating the construction of plant two. Unfortunately, because of tariff volatility, lithium prices collapsed in more than 50%. We deployed CapEx and we deployed our liquidity in Q4 2024 and in Q1 2025 towards the construction. Well, that is not so good news. We managed, we delivered throughout 2025 as we've shown. We overcame because the business was structured to generate cash flows and live through organic cash flow generation.

Speaker #1: So the effect of doubling production and tripling production is not just numeric, it's also a clear demonstration that we can be up there in the rankings with a concomitant valuation.

Speaker #1: And that is what it means for us to build long-term shareholder value. And this is what we're planning to do. This is the slide that shows how close we are to getting there.

Speaker #1: We have made a decision in the fourth quarter of 24 and in the first quarter , 25th of accelerating the construction of plant two , and unfortunately , because of tariff volatility , lithium prices collapsed in more than 50% .

Speaker #1: So, we deployed CapEx and we deployed our liquidity in the fourth quarter of '24, and in the first quarter of '25, towards the construction.

Speaker #1: Well, that is not such good news. We managed; we delivered throughout '25 as we showed. We overcame because the business was structured to generate cash flows and live through organic cash flow generation.

Ana Cabral: Here's the good news. We're almost there. We've almost finished civil foundations. What is missing really? Ordering equipment and assembling equipment, and that can be done quite rapidly. In the first plant, we were able to order equipment and assemble equipment in much less than 12 months. This is how finishing building the second plant is actually a very expedited exercise in construction, managing procurement of equipment, and managing assembly of equipment. That's it. This is a fully licensed construction, fully licensed operation. It's just within our control to do this. Sigma is very well positioned to deliver substantial returns to shareholders in 2026, and here we're going to show why.

Speaker #1: But here's the good news: we're almost there, with the civil foundations almost finished. So what is really missing? Ordering equipment and assembling equipment.

Speaker #1: And that can be done quite rapidly. In the first plan, we were able to order equipment and assemble equipment in much less than 12 months.

Speaker #1: So this is how finishing building the second plant is actually a very expedited exercise—and construction. Managing procurement of equipment and managing assembly of equipment.

Speaker #1: And that's it. This is a fully licensed construction, and fully licensed operation is just within our control to do this. So Sigma is very well positioned to deliver substantial returns to shareholders in 2026.

Ana Cabral: This slide demonstrates how Sigma continued cash flow generation, production cadence in 2026, and growth by building phase two that will yield 520,000 tons of lithium will certainly position us for a re-rating of our stock. Why is that? When you look at our peers that produce lithium, industrialized oxide from minerals in Australia, they have a larger nameplate production and a significantly larger cash flow. However, as we increase production, that means our cash flow will much more than increase because we have this competitive advantage of high margins, low costs, and operational resilience. Our increase in nameplate production will bring a disproportionately larger increase in cash flow generation. More so, that happens irrespective of pricing environment because of our low-cost operational resilience. The next slide just shows how we're gonna get there. We've demonstrated operational discipline.

Speaker #1: And here we're going to show why this slide demonstrates how Sigma continued cash flow generation, production cadence in '26, and growth up by building Phase Two.

Speaker #1: That will yield 520,000 tonnes of lithium , will certainly position us for a rerating of our stock . Why is that ? When you look at our peers , that produce lithium industrialized oxide from minerals in Australia , they have a larger nameplate production in a significantly larger cash flow .

Speaker #1: However, as we increase production, that means our cash flow will more than increase because we have this competitive advantage of high margins, low cost, and operational resilience.

Speaker #1: So our increase in nameplate production will bring a disproportionately larger increase in cash flow generation, more so as that happens irrespective of the pricing environment.

Speaker #1: Because of our low-cost operational resilience. The next slide just shows how we're going to get there with demonstrated operational discipline.

Ana Cabral: We delivered on all fronts in 2025. That's what we've seen on the right. We deleveraged and repaid debt. We increased operating cash margins. We built a new line of revenues, now selling lithium fines, high purity from our dry stack tailings. We increased mineral reserves by 40%, which shows we can operate for 66 years with one line, for over 25 years with two lines, and most likely for over 25 years with three lines. We strengthened commercial strategy by basically capturing seasonality. We monetized final prices in line with contract seasonality in Q4. We closed two significant off-takes, almost $150 million in off-takes.

Speaker #1: We delivered on all fronts in '25. That's what we've seen on the ride with the leverage and repaid debt. We increased operating cash margins.

Speaker #1: We built a new line of revenues. We are now selling lithium fines, high purity, from our dry stack tailings. We increased mineral reserves by 40%, which shows we can upgrade for 66 years with one line, for over 25 years with two lines, and most likely for over 25 years with three lines.

Speaker #1: We strengthened commercial strategy by basically capturing seasonality . We monetize final prices in line with contract seasonality . In the fourth quarter , and we closed two significant offtakes , almost $150 million in Offtakes , $96 million to fund our working capital throughout 96 , to fund our upgrade and restructuring of mining operations .

Ana Cabral: $96 million to fund our working capital throughout 2026, to fund our upgrade and restructuring of mining operations, and then a $50 million typical off-take that will basically be invested in building phase two. How are we going to continue to deliver in all fronts in 2026? We're going to resume steady state production from the mining operations. That integration, mine, plant, cadence that was shown before, that will resume the cadence of what we call the premium high-grade lithium. We're going to close financially on the off-takes transaction signed, and we're gonna close on two more off-takes as we disclose when we discuss off-takes here. We're gonna receive the development bank disbursement for the funding we already spent on phase two, and we are in discussions with several other banks for phase three.

Speaker #1: And then a $50 million typical offtake that will basically be invested in building Phase Two. So, how are we going to continue to deliver on all fronts in 2026?

Speaker #1: We're going to resume steady state production from the mining operations, that integration mined plant cadence that we've shown before. That will resume the cadence of what we call the premium high-grade lithium.

Speaker #1: We're going to close financially on the offtakes transaction signed, and we're going to close on two more offtakes as we disclosed when we discussed offtakes here. We're going to receive the development bank disbursement for the funding.

Ana Cabral: We're gonna repay $100 million of shareholder debt funded by one of the offtakes that are in negotiation, 80,000 tons per year for 3 years. We're planning to commission the plant two, the Greentech Plant 2, by the end of 2026. With that, I close, very proudly close the full year results of 2025, where we crossed the Rubicon of probably one of the most volatile lithium environments this industry has seen. We're entering 2026 awash in significant cash generation coming from numerically delivering operational efficiency. With that, I close this presentation for the full year of 2025. We're very, very proud of our team.

Speaker #1: We already spent on phase two , and we are in discussions with several other banks for phase three . We're going to repay 100 million of shareholder debt funded by one of the Offtakes that are in negotiations , 80,000 tonnes per year for three years .

Speaker #1: And we're planning to commission the plant to the green two by the end of 2026 . So with that , I close very proudly closed the full year results of 2025 where we crossed the Rubicon of probably one of the most volatile lithium environments .

Speaker #1: This industry has seen . And we're entering 2026 . Awash in significant cash generation coming from numerical numerically delivering operational efficiency . So with that , I close this presentation for the full year of 2025 .

Ana Cabral: We're incredibly proud of how we worked, how hard we worked to cross the Rubicon of one of the most volatile lithium pricing environments I have ever seen, and I've been here for 10 years as a C-level executive. We've done it without raising capital. We've done it without a hiccup in our operations. We're entering 2026 in a much strengthened position. Why? We have the resilience that's basically quantified. We already earned our revenues by building a completely different product line. We resume production cadence at the end of Q1, and we're entering 2026 with roughly $48 million of quarterly revenues, which is a significant accomplishment considering we're just coming out of a volatile 2025. All of that without raising any dollars of new capital. Pure organic disciplined cash generation. That is the quintessential competitive advantage of this company.

Speaker #1: We're very , very proud of our team . We incredibly proud of how we worked , how hard we worked to cross the Rubicon off one of the most volatile lithium pricing environments I have ever seen , and I've been here for ten years as a C-level executive .

Speaker #1: We've done it without raising capital. We've done it without a hiccup in our operations. We're entering 2026 in a much strengthened position.

Speaker #1: Why we have the resilience that's quantified . We already earned our revenues by building a completely different product line . We resume produced production cadence at the end of the first quarter , and we're entering 26 with roughly $48 million of quarterly revenues , which is a significant accomplishment considering we're just coming out of a volatile 2025 .

Speaker #1: All of that without raising any dollars of new capital, pure organic discipline, cash generation, and that is the quintessential competitive advantage of this company.

Ana Cabral: This operational efficiency delivered and quantified in the numbers we've shown you. We're very proud of our team, and I wanna thank all of our clients and stakeholders who have been there with us holding hands and helping us cross 2025 and enter 2026 in this very strengthened position.

Speaker #1: This operations efficiency delivered . And quantified in the numbers we've shown you . We're very proud of our team , and I want to thank all of our clients and stakeholders who have been there with us , holding hands and helping us cross 25 and enter 26 in this very strengthened position .

Operator 2: Thank you very much for the presentation. We will now begin the Q&A section. To ask a question, just queue the question in the Q&A button. Please be aware that your company's name should be visible for your question to be taken. Our first question comes from Fortune Era. The company has indicated a production target of 520 KT in 2027. Does this imply that plant two is expected to reach full capacity by the end of 2026? More specifically, when do you currently expect plant two to begin commissioning, and how long do you expect the ramp-up to full capacity to take?

Speaker #2: Thank you very much for the presentation . We will now begin the Q and A section to ask a question . Just queue the question in the Q&A button .

Speaker #2: Please be aware that your company's name should be visible for your question to be taken. Our first question comes from Fortune Era. The company has indicated a production target of 520 kt in 2027.

Speaker #2: Does this imply that plan two is expected to reach full capacity by the end of 2026 ? More specifically , when do you currently expect plan two to begin commissioning , and how long do you expect the ramp up to full capacity to take ?

Ana Cabral: We are going to have another presentation on plant construction, but we'll tell you what we're planning to do now. As we've shown in a slide previously, what there is between us and new production is essentially resuming ordering equipment, assembling equipment, and commissioning that plant. That can be done quite rapidly. If we use the timetable from the previous plant, it can be easily done in under a year. We are going to order equipment in the summer after the close of Q2. The reason being the offtake we just signed will be the main driver for us to deposit and prepay the equipment that we need to build plant two. We believe that it will take us anything between 8 to 12 months to actually build and commission that line. Plant two will be fully commissioned early 2027.

Speaker #1: We are going to have another presentation on plant construction , but we'll tell you what we're planning to do now . As we've shown in the slide previously , what there is between us and New production is essentially resuming ordering equipment , assembling equipment and commissioning that plant that can be done quite rapidly if we use a timetable from the previous plan , it can be easily done in under a year .

Speaker #1: We are going to order equipment in the summer after the close of the second quarter, the reason being the offtake we just signed will be the main driver for us to deposit and prepay the equipment that we need to build.

Speaker #1: Plant two—we believe that it will take us anything between 8 to 12 months to actually build and commission that line. So, Plant two will be fully commissioned early 2027.

Ana Cabral: As a result, the guidance for 2027 is not a guidance for production, it's a guidance for installed production capacity. We will be further updating the markets as that unfolds. What we can say is we're almost there with three-fifths of our timetable accomplished in the construction of Plant 2. What stands between us and that level of production is purchasing, building, and commissioning, which we've shown we can do quite rapidly.

Speaker #1: And as a result, the guidance for '27 is not a guidance for production. It's a guidance for installed production capacity. And we will be further updating the markets as that unfolds.

Speaker #1: But what we can say is we're almost there, with three-fifths of our timetable accomplished in the construction plan, too. And what stands between us and that level of production is purchasing, building, and commissioning, which we've shown we can do quite rapidly.

Operator 2: A follow-up question. In the guidance section titled Cash Flow Forecast at Various Realized Lithium Prices, could you please clarify whether the price assumptions of $1500 and $1700 refer to Sigma's expected average realized selling price for its concentrate or the benchmark SC6 China FOB price? For Sigma's concentrate grade of approximately 5.2% to 5.5% lithium oxide, what is the typical realized price as a percentage of the SC6 benchmark price?

Speaker #2: A follow-up question in the guidance section, titled 'Cash Flow Forecast at various realized lithium prices.' Could you please clarify whether the price assumptions of $1,500 and $1,700 refer to Sigma's expected average?

Speaker #2: Realized selling price for its concentrate, or the benchmark S6 China FOB price for Sigma's concentrate grade of approximately 5.2 to 5.5%.

Speaker #2: What is the typical realized price for lithium oxide as a percentage of the SC benchmark price?

Operator: Ana, you are on mute.

Ana Cabral: Yeah, you're mute. Let me unmute. Apologies. We are using, we're not using the gross prices, we're using adjusted prices. When you think about the nameplate price, we take nameplate price from SMM, and then we typically ship 5.2, 5.3 lithium oxide grade product. The adjustment is done dividing that level of oxide by SC6 in older contracts. In the newer contracts, we divide it by 5.5. The results are kind of the same. When you look at the prices on that table, they are net prices. As you probably are all aware, gross prices have reached 2,400 just two days ago. 1,800 and 1,500 are far below the current level of nameplate prices at Shanghai Metals Market.

Speaker #3: Anywhere in mute .

Speaker #1: Unmute me . Unmute . Apologies . So we are using . We're not using the gross prices . We're using adjusted prices . So when you think about the nameplate price , we take nameplate price from SM .

Speaker #1: And then we typically we typically ship 5.2 , 5.3 . Lithium oxide . Grade product . So the adjustment is done dividing that level of oxide by SC six in order contracts in the newer contracts we divide by 5.5 .

Speaker #1: The results are kind of the same. So, when you look at the prices on that table, they are net prices. You probably are all aware gross prices have reached $2,400.

Speaker #1: Just two days ago. So 1,000, 801,500 are far below the current level of nameplate prices at Shanghai Metals Market.

Operator 2: Our next question comes from Lamartini Gomes. Question for Ana Cabral. Can you give us your directional sense of how much each +$10 per barrel increase in oil prices impacts the demand for lithium?

Speaker #2: Our next question comes from Lamartine Gomes. Question for Ana Cabral: Can you give us your directional sense of how much each plus $10 per barrel increase in oil prices impacts the demand for lithium?

Ana Cabral: Unfortunately, I don't have that number, and I am not really an oil expert. What we can say though is 15% to almost 20% of the fossil fuels we use here are just the fuels that power the trucks that run around our operations. In other words, every liter of diesel in Brazil has mandatorily 15% of biodiesel. Now, that percentage is slated to increase. So we actually are, let's put it that way, 20% less impacted by the increase in diesel prices than any other country in the world because we have this fantastic, we call biofuels program in the country, which was actually created, thirty years ago during the last oil crisis for this exact reason for energy security of Brazil. We are the beneficiary of that when it comes to our emissions.

Speaker #1: Unfortunately, I don't have that number, and I am not really an oil expert. What we can say, though, is 15 to almost 20% of the fossil fuels we use here are just the fuels that power the trucks that run around our operations.

Speaker #1: In other words , every liter of diesel in Brazil has mandatorily 15% of biodiesel . Now , that percentage is slated to increase .

Speaker #1: So we actually are . Let's put it that way , 20% less impacted by the increase in diesel prices than any other country in the world , because we have this fantastic we call biofuels program in the country , which was actually created 30 years ago during the last oil crisis for this exact reason for energy security of Brazil .

Ana Cabral: Our trucks generate 20% less emissions because the fuel by law has 15, and we're putting 20-ish% biofuels for every liter of diesel.

Speaker #1: And we are the beneficiary of that when it comes to our emissions. So our trucks generate 20% less emissions because the fuel, by law, has 15, and we're putting 20% biofuels for every liter of diesel.

Operator 2: Our next question comes from Robert Cook. Please detail the timing of phase 2 and 3 to completion both 2028. Anything more specific?

Speaker #2: Our next question comes from Robert Cook. Please detail the timing of Phase Two and Three to completion—both 2028. Anything more specific?

Ana Cabral: Well, I was mentioning what we're gonna do on Phase 2. Again, we're gonna keep giving the markets updates pretty regularly on that. Phase 2, by the summer, we're gonna be ordering equipment. Close Q2, order equipment. As we demonstrated, that will be funded by the growth offtake we signed. $50 million are more than enough to prepay or deposit towards the equipment we need. To be specific, now what's between that ordered equipment and production is essentially assembly. In the previous plant, we had 1,000 men on-site assembling that plant, you know, that line. That was done in eight months. We used what we call air procurement for some of the parts that were delayed so that we could cut short delivery times.

Speaker #1: Well, I was mentioning we're going to do phase two. And again, we're going to keep you updated with the market pretty regularly on that phase two.

Speaker #1: By the summer , we're going to be ordering equipment . So close . Second quarter order equipment as we demonstrated , that will be funded by the growth offtake we signed $50 million of more than enough to prepay or deposit towards the equipment .

Speaker #1: We need to be specific . Now , what's between that order equipment and production ? Is essentially assembly in the previous plan , we had .

Speaker #1: A thousand men on site assembling that plant that you know, that line that was done in eight months. We used what we call air procurement for some of the parts that were delayed so that we could cut short delivery times.

Ana Cabral: We used a lot of what we call acceleration techniques, which in this budget are factored in. If we use the accelerated timetable, it means we're gonna spend under $7 million for extra men, extra shifts, and air freight for some of the equipment. What does that mean? It means that we could have a built plant by Q1 2027, assuming we start in the summer. There's commissioning. What is the advantage of doing a plant that is a carbon copy of a plant we've been operating by then for almost four years? That is the plant we really know. As a result, we believe we can cut commissioning times significantly. More importantly, start benefiting from the get-go, begin with the same levels of recoveries.

Speaker #1: We used a lot of what we call acceleration techniques, which in this budget are factored in. If we use the accelerated timetable, it means we're going to spend on $7 million.

Speaker #1: For extra men , extra shifts and air fried for some of the for some of the equipment . What does that mean ? It means that we could have a built plant by the first quarter of 2027 , assuming we start in the summer and then there's commissioning , what is the advantage of doing a plant that is a carbon copy of a plant ?

Speaker #1: We’ve been operating by then for almost four years. That is the plant we really know. And as a result, we believe we can cut commissioning times significantly.

Ana Cabral: Instead of going through the curve of going, starting with 50% recoveries up to 70% recoveries we underwent from the 2.0 version of the plant to the 3.0 version of the plant. Without being more specific, we're quite confident that we're gonna have plant two by, you know, any time in H1 next year. That's the reason why we're making a clear distinction between installed production capacity and production. Production is dependent on the commissioning, and we're gonna keep the market vastly updated as we go along. Now, plant three.

Speaker #1: And more importantly , start benefiting from the get go . Begin with the same levels of recoveries . Instead of going through the curve of going , starting with 50% recoveries , up to 70% recoveries , we underwent from the 2.0 version of the plant to the 3.0 version of the plant .

Speaker #1: So, without being more specific, we're quite confident that we're going to have planned to buy, you know, any time in the first half of next year.

Speaker #1: But that's the reason why we're making a clear distinction between installed production capacity and production. Production is dependent on the commissioning. And we're going to keep the market vastly updated as we go along.

Ana Cabral: Plant three is what we're very proud of actually, because given our operational success, given our cost resilience, and given our strength as a business throughout cycles, which will be shown basically in 2025, has not gone unnoticed by the main development banks throughout the world, by the main players throughout the world, by the main financiers throughout the world. We do have dialogues going on for building plant three. Building plant two and three together is not new. In fact, in December 2022, when we filed our DFS for expansion, that was the plan. So much so that we invested in building infrastructure for three lines. The goal was to do one, two, and three sequentially and maximize what we call construction synergies. Unfortunately, lithium took a tumble in 2024, and we quickly aborted that plan, and we stuck to just the first plant.

Speaker #1: Now plant three , plant three is , well , we're very proud of actually , because given our operational success , given our cost resilience and given our strength as a business throughout cycles , will be Schoen basically in 2025 has not gone unnoticed by the main development banks throughout the world , by the main players , throughout the world , by the main financiers , throughout the world .

Speaker #1: So we do have dialogues going on for building plant three , building plant two and three together is not new . In fact , in December 22nd , when we filed our DFS for expansion , that was the plan .

Speaker #1: So much so that we invested in building infrastructure for three lines. The goal was to do one, two, and three sequentially and maximize what we call construction synergies.

Speaker #1: Unfortunately , lithium took a tumble in 24 and we quickly aborted that plan . And we stuck to just the first plant . By the end of 24 , we resumed plant two and we went all in again with the volatility of tariffs in 25 , we aborted that plan and we stuck to plant one .

Ana Cabral: By the end of 2024, we resumed Plant 2, and we went all in. Again, with the volatility of tariffs in 2025, we aborted that plan, and we stuck to Plant 1. Doing one, two, three is actually what we have been designing this industrial complex for. Why? We spent the money in the infrastructure, and that was not a small feat. Meaning we have the water to feed three lines. We're licensed to feed three lines. We have the sewage inbound treatment station to feed three lines. We have the power substation to feed three lines. So from an infrastructure point of view, we are ready for three lines. This is why we're delighted to actually say that that has not gone unnoticed.

Speaker #1: But doing one, two, three, it's actually what we have been designing this industrial complex for. It's why we spent the money on the infrastructure.

Speaker #1: And that was not a small feat, meaning we have the water to feed three lines. We're licensed to feed three lines.

Speaker #1: We have the sewage inbound treatment station to feed three lines. We have the power substation to build to feed three lines.

Speaker #1: So from an infrastructure point of view, we are ready for three lines. And this is why we are delighted to actually say that that has gone unnoticed.

Ana Cabral: We have, let's say, no shortage of choices from where to get funded with the appropriate kind of debt, development financing debt, to build these three lines.

Speaker #1: And we have, let's say, no shortage of choices for where to get funded with the appropriate kind of debt, development financing, debt to build these three lines.

Operator 2: Our next question comes from David Fang with CICC. Can we have some color on how Sigma would mitigate any potential fluctuations in fuel costs and power costs? What percentage does diesel cost account for in your cash costs or AISC?

Speaker #2: Our next question comes from David Fang with C I c c . Can we have some color on how Sigma would mitigate any potential fluctuations in fuel costs ?

Speaker #2: And power costs? What percentage does diesel cost account for in your cash costs or ASIC?

Ana Cabral: I don't have the number by heart, but I can talk about power. It will have zero effect on power. In other words, when you think about power, our power is fixed at two cents of a dollar, meaning $0.02, two cents of a dollar per kilowatt hour. This is fixed. One important point, power is renewable here in Brazil, so it's coming from a hydroelectric dam. We have a five-year agreement, which is set to expire two and a half years from now. We're gonna be good with power. Diesel, it's the element that is a little bit less straightforward to explain. First, because we got biofuels in the mix, and that is mandatory by law.

Speaker #1: I don't have the number by heart , but I can talk about power . It will have zero effect in power . In other words , when you think about power , our power is fixed at $2 per kilo , $0.02 of a dollar , meaning $0.02 $0.02 of a dollar per kilowatt hour .

Speaker #1: This is fixed . One important point . Power is renewable here in Brazil , so it's coming from A hydroelectricity dam . And we have a five year agreement which is set to expire two and a half years from now .

Speaker #1: So we're going to be good with power diesel is it's it's it's the element that is a little bit less straightforward to explain first , because we got biofuels on the mix and that is mandatory by law .

Ana Cabral: Secondly, because our oil company is state-owned, and they have what we call a diesel compensation account, which works like a shock absorber during oil crisis. In other words, the diesel costs don't go straight to the consumer as they increase globally. Petrobras absorbs some of that shock initially, using what we call the oil compensation account, and then it releases in the market. That was created because all transport in the country mostly is done by trucks, so that trucks are individual entrepreneurs, so that they have time to plan to actually send that cost into their customers. We're going to revert back to you on the percentage of diesel in our cost with that knowledge.

Speaker #1: Secondly, because our oil company is state owned, and they have what we call a diesel compensation account, which works like a shock absorber during oil crises.

Speaker #1: In other words, the diesel costs don't go straight to the consumer as they increase globally. Petrobras absorbs some of that shock.

Speaker #1: Initially, using what we call the oil compensation account, and then it's released in the market. And that was created because all transport in the country, mostly, is done by trucks.

Speaker #1: So that in trucks are individual intrapreneurs . So that they have time to plan to actually send that cost into their customers . So we're going to , we're going to revert back to you on the percentage of diesel in our cost with that knowledge
