Marcelo, you have the floor. Thank you, Leonardo.

Ladies and gentlemen, a very good afternoon to all of you. It's a pleasure to be here with you to share the results of Q4 and the full year of 2025.

2025 was a challenging year for Usiminas and for all the steel Brazilian industry, and once again, the opportunity of growth and generating income and jobs was compromised due to unfair import of steel and these were manufactured products. In 2025, we reached an adjusted consolidated EBITDA of R$2 billion with a growth of 24% vis-a-vis 2024 and a margin of 8%.

One of the main drivers to improve the result was the cost drop of the steel units totaling -5% of cost to sell per ton. This was more than offset the lower net revenue per ton that was 4%.

In Mineração, the highlights were a record volume of sales of iron ore totaling 9.6 million tons, a high of 14% vis-a-vis 2024, and quality discounts that allowed us to attain better results. For the first quarter of 2026, in the steel unit, the company projects stable steel units sales, and in the domestic market, connected to seasonality, we expect a recovery of net revenue per ton driven mainly by a sales mix that is more noble and higher prices.

On the other side, the cost per ton will increase reflecting the most favorable mix, and with this, we project EBITDA and EBITDA margins above the last quarter. Now in the mining unit, the expectation is of lower sales volumes due to the seasonality of the rainy season and prioritizing better areas of better profit.

The prospect of the economic scenario is moderate for 2026, sustained by a gradual growth of 1.8% of the GDP presented in the Focus report. Within this context, the expectation of the steel Brazil industry is increase, but this growth will be totally absorbed by the expected growth of imports of 4%.

If we don't have effective measures of commercial defense against unloyal competition, the import volumes in the steel chain have been investigated and confirmed the urgency to be implemented fast. The government has reacted, as we can see in the recent anti-dumping rights and to elevate the tariffs by 9%.

Now we manifest our recognition by the serious technical work by the Ministry of Industry and Commerce in the analysis of the commercial lawsuits. This is important to foster more competitive value.

Usiminas is prepared to capture the opportunities of this new context, meeting the ever-growing demand of its customers. At the same time, as we maintain attention to the market in order to curtail the possibilities of not following this that are a result of an over- surplus of Chinese steel in the international markets, and this impacts the national industry.

Our internal agenda for 2026 will be focused on reducing costs, efficiency in our industrial operations, and a strong financial discipline, and strong environmental discipline. It will be important to ramp up our priority CAPEX like the PCI plant, the coke batteries repair, and the new gas meter.

These projects will reassure the sustainable growth and the competitiveness of Usiminas at the long run. We would also like to thank all of our employees for their effort, their engagement, as well as our suppliers, clients, shareholders, and the community for the trust and for the sound relationship that we built throughout the years, and we are confident that 2026 will be a very good year.

Thank you very much. Hello?

Thiago, you may proceed. Good afternoon to everyone.

These are the highlights of the year. Our steel sales throughout the year was 4.4 million tons.

It was the second greatest in the past 10 years. The growth is of the export, and the volumes of the domestic market will remain stable.

The mining unit presented production and a record sale. The adjusted EBITDA was R$2 billion, a strong growth of 46% in mining and 16% in steel unit.

The free cash flow of R$1 billion reflect the EBITDA generation, working capital in R$838 million, is partially offset by the CAPEX of R$1.2 billion. The year ends with a net cash of R$444 million, the result of the flow of free cash flow and depreciation of the BRL vis-a-vis the dollar.

Now we had R$1.4 billion in net debt. Now our next slide.

Now the net revenue was R$6.2 billion, a growth of 6.5% vis-a-vis the past quarter, mainly because of the reduction in the steel unit with registered the lowest price per ton. Now this effect was partially offset by 4% increase in the mining unit and by higher prices, although there was a slight drop.

This wasn't affected. The EBITDA was slightly before the past quarter.

Now we had R$2.9 billion that was affected by the impairment of the past quarter. Now the fourth quarter ended with a profit of R$129 million.

Now let's go to the next slide. In the steel unit, the annual volume in sales was robust, and there was a growth in export.

The sales volume in the quarterly basis dropped 2%. There was 3.3% in terms of drop in the domestic market, but aligned with Q4, showing us the seasonality.

The net revenue reflects the drop in the net revenue per ton because of the import. We have a less favorable mix during Q4.

EBITDA improved with the improvement of costs, although we were in an environment of unfavorable pricing. The deterioration of the net revenue per ton impacted the EBITDA by 26% when we compare it to the past quarter.

The adjusted EBITDA was negatively impacted by a less favorable sales mix with products of lower margin. The gain of the CPV of steel mills due to lower prices of raw material partially offset this impact.

In addition, during Q3, there was an extraordinary sales of fixed assets that wasn't repeated during the fourth quarter. In mining, last year, we ended with a record sales volume and production.

As a result, the annual net revenue increased 27%, although there were lower price. The net revenue per ton reflects lower discounts due to penalty and exchange rate due to the average exchange rate throughout the year higher by 3%, and the Platts references dropped $7 per ton.

Analyzing the profitability of the business, the EBITDA per ton dollar increased 2%, although there was negative pressure. Throughout the quarter, the sales volume presented a slight drop of 2%.

Despite this, the total net revenue increased 4%. This reflected better prices in the quarter, and here we had $4 in terms of the price of reference.

When we see the revenue, EBITDA dollar increased $4 per ton, aligned with the reference prices. Now our financial indicators.

The net operational cash flow was R$1.1 billion of an EBITDA of R$470 million, a reduction of working capital R$576 million. The working capital variation was because of a drop in accounts receivable and an increase accounts payable, R$192 million.

The CAPEX was R$372 million, and we reached R$1.2 billion, aligned with the guidance between R$1.2 and R$1.4 billion. This way, the free cash flow of the quarter was R$744 million.

Throughout the year, the free cash flow was R$989 million, mainly reflecting the EBITDA generation and working capital that we mentioned beforehand. It was partially offset by the CAPEX of R$1.2 billion.

Now throughout the quarter, we went from a net debt of R$327 million to a free cash of R$444 million, reflecting the free cash flow of R$744 that we already mentioned. The gross debt increased around R$6 million due to the appreciation of the dollar.

Now throughout the year, there was a significant drop of R$1.4 billion in our net debt. This was due to the strong cash generation, ending with 0.22 negative leverage.

Usiminas ends the year with a sound debt profile with no extraordinary maturities up till 2028. Leo?

Thank you, Thiago. Now we go to the Q&A session.

Marcelo, first question from Gabriel Barra from Citi, Marcio Farid from Goldman Sachs, they want to know about Compactos and mining. Gabriel says with the changes in the share Formosa, and he wants to know if there is an update of the project Friáveis Formosa.

Good afternoon to everyone, and let's say there have been no changes. Yes, we do have a robust plan in the short, mid, and long run strategy, and we continue making progress with our licensing program of Compactos.

This year, we will have news and we will see possible instrumentations. Regarding the Friáveis project, we are constantly reviewing our exploration strategy, as well as mines or mining operations, and we've created important efficiencies and synergies, and we believe that the prospects for the short and mid run will be to be continuous in terms of friable material.

Thank you, Marcelo. Questions about anti-dumping, what are we going to do?

There are a number of questions regarding anti-dumping. I'm going to try to divide them in blocks to be efficient.

Gabriel Barra from Citi, Guilherme Libe from XP, with the approval of the anti-dumpings, what should we expect for hot-rolling mills that will be approved by the end of the year? Guilherme basically asked the same thing, will we have a definition regarding this request?

Leo, good afternoon, Gabriel and Guilherme. As Marcelo stated, this definition was published yesterday for measures for hot-rolling mills and galvanized.

As we have reported anti-dumping actions from China, and finally, the soundness of these cases were confirmed by the definite measures that were published yesterday. We expect the same type of scenario with hot-rolling mill and the hot-rolling mill according to the preliminary publication.

Now the timeline would be July this year for a definite measure. We would also like to remind you that the deadline would be in December due to the importance of the measures and the high impact that these imports have in the steel industry in the Brazilian market.

We feel reassured that this will be resolved by the middle of this year. Thank you, Miguel.

Our next question from Ricardo Monegaglia, Safra, Marcelo Arazi, BTG, in your view, dumpings are valid as of when? Marcelo Arazi wants you to give us details regarding the tariffs that were applied yesterday.

What kind of consequences can we expect from here on? Now the measure is valid as of the publication, and the measure for cold-rolling mill is Now for the coils would be as of the day of the publication, and most we expected to be next week.

The impact will be positive for the industry and the market when we see the imports from China of these two products, they exceed 1.5 million tons during the past 12 months. In this sense, we would have greater possibilities to sell to the local industry, and Usiminas will be prepared to cater part of this market.

Now regarding any concern regarding ways of not complying with this measure? We want to know how to evaluate the risk of triangulation of import volume because the measures were geared towards China.

How do you see the effectiveness of this anti-dumping for galvanized products and cold-rolling mill? Marcelo says can we see volume be redirected via Vietnam?

How to see this triangulation risk? He wants to know if these measures are sufficient to see sound margins in the sector once again.

What do we need in order to have a profitable industry structurally? The first step...

De facto, what was published yesterday is important to correct the distortions created by this unfair competition. There are risk because there is a surplus in global steel because of the Chinese production.

Production last year in China was above 130 million tons, this created negative impacts in different markets. Obviously, as we presented here in Brazil, we were one of the markets that was most impacted by these imports.

Now we have to continue observing, we're working together with government agencies because we don't want this risk to impact us during the upcoming months. When you analyze the anti-dumping measures for cold-rolling mill at worldwide level, today there are 40 cases.

Out of the 40, 12 are against China, and the second, third country with the greatest amount of cases is Vietnam and Korea. There is a risk.

We have to continue monitoring. We are working together with the agency in order to avoid these future risks, and we trust that the government as of yesterday's definition can see the critical situation of the industry and the worldwide steel industry.

Thank you, Miguel. There are more add-ons here.

Marcio Farid from Goldman Sachs, Gabriel Barra, Citi, Caio Ribeiro, Bank of America, Marcelo Arazi, BTG, Tachi Kangini from J.P. Morgan, and Ricardo Monegaglia, Safra, everybody wants to know about the next steps.

What is the main strategy after tariffs and anti-dumping? Is it volume or prices?

Which effects can we expect throughout 2026 due to these measures? If Usiminas will be more proactive in price transferring this year?

I want to see if there's a different add-on here. Ricardo wants to know with the combination of increase of 25 NCMs, anti-dumping, how can the discussions in price?

If there is an impact in the number of orders when you see these changes? Miguel, you have the floor.

Many questions. Let's see if I can answer all of these questions here in my answer.

Let's start with the market. We expect a market in 2026 with a growth of consumption of flat steel of around 1%, highly aligned with the expectation of the GDP growth.

If we see a similar market, 2025, 2026, we analyze the total volume of imports of flat steel in 2025 was around 4 million tons, and around 60%, 65% comes from China. Therefore, we can conclude that we do have important space to resume our participation in domestic market in that consumption of flat steels in Brazil.

Now within this scenario, we would have greater market share, a potential increase in internal sales, and better mix of product sales when we compare it to export. Now when we see the price, for instance, we see a strong pressure in terms of revenue because of the high imports and unfair competition, which affected our prices and profit.

We have to become profit again to face the needs of technology and the face of investments that we have in CAPEX plan. We can resume our profit if we have better prices and margins during the upcoming months.

Now Daniel Sasson from Itaú BBA, Tachi Kangini, J.P. Morgan, and Ricardo Monegaglia from Safra.

We know that great part of the volume of galvanized products goes to the automobile industry that is not exposed to export. Will you change your negotiations with the automobile industry in April?

Do you believe that the contracts that will be signed in the upcoming months will be readjusted? Will they be affected by these anti-dumping measures?

I would like to clarify around 60% of coated products are for the automobile industry. As they follow yearly contracts.

Part of these contracts are renewed in January, the other part are renewed in April. The contracts that were renewed in January have a cost reduction of 2%, 3%, as we already explained in other calls.

The negotiations of the auto industries are not impacted by these imports. They're very little impacted by the imports because this is flat steel, we don't expect any impact in the negotiations that will take place in the contracts that will be renewed in April.

The expectation is to close these contracts at similar levels from January. The contracts of January represent 25% of our total revenue for our sector industry.

Thank you, Miguel. More about this subject, Ricardo Monegaglia wants to know how many measures to normalize the inventories in the industry for imports post tariffs?

This is an important point, as a matter of fact. The strong increase of imports throughout the year elevated the inventories of the importers.

Now the chain, according to the last INDA report, the inventories for the chain increased, and today would be around 4 months. Our view is that the inventories for the importers are above 6 months.

Now the regularization will take some times, will depend the dynamic of the consumption, but it's important to understand that great part of these inventories are characterized by commercial products with no added value, and in our focus during the past year is greater share in greater added-value products, especially geared towards the industry. We could see a gradual reassumption for more commercial products, and obviously with very little impacts for the industrial sectors or the auto industry.

Miguel, still the import costs. Is there space to request to the government increase of the tariff to 25 25% for more NCMs?

We are optimistic and we are positive the increase of nine NCMs for our sectors done by the government. The government is seeing different tools to mitigate the impacts of unloyal competition in all industry.

I would not discard the use of these tools in the future to minimize the risks and the impacts, especially when we talk about triangulation or circumvention from other origins. Igor Guedes from Genial, we would like to have an idea what about your cold-rolling mill?

How much does this account in your sales? Now, cold-rolling mills in the domestic market, yeah, it accounts for what kind of share?

Igor, our cold-rolling mills would be around the cold-rolling 1 million tonnes. Now, of course, the import and the loss of share in local steel mills have reduced this volume.

It is important to clarify that we have the capacity to increase the production of cold-rolling in order to rectify this problem that we had due to unloyal competition. Marcelo, here the focus would be more on the operation.

Igor Guedes from Genial wants to know, do you expect these anti-dumping measures to improve the domestic demand at a point that you will reactivate the blast furnace that is closed? Would you turn on this disconnected blast furnace?

Igor, excellent question. I can make a comment here regarding the productive structure of our blast furnaces in Ipatinga.

We invested R$2.7 billion in blast furnace 3. With this retrofit and all the ramp-up process, in addition to we are ending the PCI powder coal injection that goes through the upper side of blast furnace 3, and we will be able to inject all the furnace systems.

All of these measures have allowed us today to be able to replace of one of the blast furnaces operating with blast furnace 3 that has over 3,000 cubic meters and 2,800 cubic meters. Today, the capacity is to have productions that are equivalent to the three blast furnaces.

Yes, we can supply and increase our steel capacity. We do have capacity.

We are regulating the production capacity according to market conditions, and we are prepared to use a virtual blast furnace, one with the new performance that we achieved with the new blast furnace 3 that was developed. Marcelo, now a question from Guilherme Nippes regarding Musa, if you could better quantify the drop of volumes for 2026 and the volumes expected for 2026.

Now the first quarter is highly associated to the seasonality of rainy season. In this year, rains are intense, and this affects logistic, mines, and this is aligned with what we expect for the year is a full alignment.

According to iron ore indicators, we have developed an operation system that is extremely flexible, which allows us to define routes of operation at marginal costs which are properly identified in such a way if we see price conditions that favor of full sales, we will use this. This is something that we will monitor throughout the year.

We will monitor this evolution, and we will adapt our production to this market dynamic. Thank you, Marcelo.

Thiago, regarding capital allocation, Daniel Sasson, Itaú BBA, Tachi Kangini from J.P. Morgan ask a question.

You have net cash. What is your capital allocation from here on?

Is there space to improve the balance structure? Is there space for more investments?

Thank you for your question. Now regarding capital allocation, we have already carried out a CAPEX guidance of 1.6 billion, which is significant.

We have other CAPEX that have been approved. Marcelo, I don't know if you would like to give us information regarding Compactos, but there's not much more to mention.

As Thiago just stated, now we ended the investment cycle connected to blast furnace and auxiliary circuits. Today, we have a major product that was approved that was the coke battery number four of 1.7 billion that will give us self-sufficiency in coke during the upcoming three years.

At the end of this project, together with the hot repair that we're performing on battery three, that is working exceptionally with excellent impact in emissions reduction. Let's say we have a clear measure of emissions very low, at a record low in the history of Usiminas, and I can convey that our focus on the environmental performance has gone hand in hand with priority match management, and we have capitalized these investments to make our industrial management environmental more robust.

We have the PCI project, powder coal injection, we're ending it during the first semester, as I mentioned, and we have the new gas meter. This CAPEX of 1.6 billion billion is totally aligned to our strategy to improve cost competitiveness and environmental performance.

In terms of Compactos, as I mentioned at the beginning, the intention is to continue with the environmental licensing and throughout 2026, and at the end, we will see how to give continuity, as I mentioned in the beginning. We have a clear view that Musa is a strategic asset for us, and we can see how we can continue the operation in the long run.

Thank you, Marcelo. You answered the next question from Rafael Barcellos of Bradesco about the guidance and to talk about the CAPEX of 2026.

Thiago, regarding cash flows, Guilherme Nippes, XP, Rafael Barcellos wants to know the free cash flow was strong during the quarter with the lengthen of accounts receivable and working capital help us. What can we expect from here on?

Is there space for improvement that comes from these lines? Rafael says, how should we think about the working capital during 2026?

I think that we reached a level of working capital that will be stable, and in the future, will be changed because of the effect of prices and volumes. It is not reasonable to think a new year with a release of working capital like we saw in 2025.

Thank you, Thiago. Marcelo, regarding the productive structure, Carlos De Alba from Morgan Stanley wants to know, due to the footprint of Ternium in the Americas, does Usiminas want to invest in an electric furnace in Brazil, like in Cubatão?

Let's say. As I said, well, the upstream was disconnected years ago, but there's a downstream that is exceptional.

Now the hot-rolling mills of Cubatão is one of the most modern from the Americas. It has over 10 years of operation, but it is at a state of maintenance and the technological update.

This is an interesting asset to maximize and to meet the demand of all the domestic market in all segments, industrial, oil and gas. An electric furnace would mean we have to justify this clearly in terms of volume growth.

This will depend on market conditions and the evolution. According to the current situation, with the strong impact of imports and the low consumption of steel in Brazil, this is still not in our radar in the short or mid run.

This is a plant that has an interesting profile in its structure because it has a steel mill area that is perfectly conserved and it can be activated if it's convenient, but this is not something that we have in our radar in the short or mid run. Thank you, Marcelo.

Miguel, some questions regarding negotiations with the auto industry. How were the negotiations with the auto industry in January in 2026, and what do you expect in April, and when will you review these contracts?

Guilherme Emerson, as we mentioned, the auto contracts that were renovated in January had a 2%, 3% discount. I would like to remind you that these contracts account for 25% of the total sales to the auto industry.

Now the contracts that are renewed in April that are under negotiation, the expectation is to close at similar levels to that of January. Most of these contracts are signed on a yearly basis, some of them are reviewed every 6 months.

Thank you, Miguel. Miguel, regarding prices, Guilherme Nippes from XP, Emerson Vieira, Goldman Sachs, Rafael Barcellos, Bradesco BBI, how do you see the domestic performance of prices throughout the first quarter?

What do you expect in terms of the sales mix, if you can tell us how this will work between industry sector? Now Emerson says that the price of Q4 was affected by the mix change.

Can we already see this in January or February, or the expectation of normalization is for March? Rafael wants to better understand the magnitude of the average price.

We've increased prices for distribution sector generally by 5%. For industry, most of the contracts were renewed as of January, following the trend of the price increase that comes from Q4.

All these contracts are delayed in 3 months in the auto industry. As I mentioned, there is a discount of 2%, 3% for a very small part of these contracts that were renovated in January.

Now regarding the mix, we expect our sales mix to normalize in the domestic market during Q4, going back to a sales mix which was historic in Usiminas that we can classify as 1/3 of sales for the auto industry, 1/3 for distribution, and the other 1/3 for the industry. I think that this is the color regarding the expectation of this first quarter.

Now you spoke about normalization as of January or March. I think that most of the auto industries came back from the holiday vacations after the first fortnight of January.

After the first 15 days, we can see the normalization of the sales mix here. Thiago, now we have questions regarding costs, Thiago.

I'm going to try to bundle them. Now Guilherme Nippes from XP and Emerson Vieira from Goldman Sachs want to know the following.

Can you give us more visibility regarding cost improvement due to efficiency in order to capture this in the upcoming quarter, and how do you see the evolution of costs during Q1? Emerson basically says, what can you say about space for continuous gain of efficiency in costs?

Now regarding the next quarter, as Miguel mentioned, with the normalization of the sales mix, we will increase costs because we are selling material of greater value. This will be more than offset by the revenue per ton.

This is why we have a favorable outlook for the next quarter. Now regarding efficiency gains, this is one of our continuous targets.

I don't know, Marcelo, if you would like to say something. As Thiago mentioned, our main focus is the improvement of efficiency, especially industrial processes throughout this semester.

We already systemized the coal injection system for the blast furnace, and progressively, we will replace an important part of coke consumption by coal, and this generates important efficiencies and cost reduction. Throughout 2026, we will continue consolidating these type of projects that allow us to improve our sales cost in a systematic fashion.

We are more robust in terms of profitability. With this, we also answered Tachi Kangini's question that was price.

Now, Thiago, still on costs, Rafael Barcellos from Bradesco BBI and Igor Guedes want to know how the recent increase of coal prices will affect costs. The drop of COGS that was stronger than we expected, some inputs that went through the PML bought in the past at a lower cost, the coal price increase, how do you see the cost from here on?

How long does this last? How long does the price transference last?

For the next quarter, we do not see these effects. The effects of the increase of coal prices, we will feel this especially during the second quarter.

This will not have an effect during Q1 and probably during Q2. Thank you.

Thiago, still for you. A question from an individual, Nilberth [Nascif?]

, [Noiberth?] , I don't know, the payout to shareholders, is there any forecast of payouts for shareholders?

Payout, last year we had an important loss because of the impairment, and because of this, for the time being, we are not thinking about paying dividends regarding last year and because accrued profits, but we will always assess the situation of the company, and one of our targets is to continue paying our shareholders. To end, we have a question from Gabriel Barra from Citi.

He wants to know the transition of the position of CFO, if there will be an important change in focus. Could you talk about your priorities at the short run, in the long run for this new position?

Thiago, we will finish with this. Thank you, Gabriel.

The transition is okay. I found a financial team that is spectacular, and they are helping this transition to be swift, organized, and I would like to thank everyone.

Now regarding focus, well, I believe due to the challenging environment of the industry, it is important to have control in cost and cost efficiency, and we need discipline in our CAPEX as well, and we will be focused on this. With this, we ended our Q&A session.

We would like to thank everyone for your participation, and should you have any doubts, our IR team is at your disposal. Thank you very much, and have a good afternoon.
