Q1 FY2026 · Earnings Call TranscriptApril 28, 2026

Olof Grenmark

Ladies and gentlemen, I'd like to welcome you to Boliden's Q1 2026 results presentation. My name is Olof Grenmark, and I'm Head of Investor Relations.

Today, we will have a results presentation led by our President and CEO, Mikael Staffas, and our CFO, Håkan Gabrielsson. We will also have a Q&A session led by the operator.

Mikael, welcome.

Mikael Staffas

Thank you, Olof, and welcome to all of you. We are welcoming you from Askersund.

For those of you who are maybe non-Swedes and wonder where that is, that is the closest bigger municipality to Zinkgruvan. We will have our AGM here in a couple of hours, following the tradition that we try to have our AGMs close to our operating sites.

Now, regarding the quarter. The highlights for the quarter is that we've had a good production quarter.

We're coming in with a EBIT, excluding the process inventory revaluation, of around 4.4 billion Swedish krona, and also a strong cash flow. Strong cash flow, also considering that Q1 is normally a relatively weak cash flow quarter.

We've had solid performance in both of our operating units, we've had it in mines and in smelters. Then on top of that, we have strong metal prices.

With our business model with definite pricing coming a little bit later, we of course benefit from having strong metal prices then when revaluating previous period's deliveries. The gold and silver production has also been very strong in the smelters.

Regarding the Garpenberg incident, I'll come back to that one, but the impact on the financials for the quarter has been 400 million negative on volumes and 700 million negative from a one-off write-off of assets connected to that. In Odda, we have managed in the quarter to start the ramp-up of the expansion project.

We had the first feed, I think, on March 31, and I'll come back to that also in a little while. The financial performance in general has been strong with a strong cash flow.

The CapEx in the quarter is right around where it should be according to our budget and according to what we have guided to you. On Garpenberg, I think it's time to take a little bit just so we get these numbers more in perspective.

As you all know, we had a rock fall and followed by seismic events that happened in mid-March. What then happens is basically three things that we need to separate.

In Garpenberg, we have all together 105 million tonnes of reserves. The upper part of Lappberget is 14 out of those 105, and we have 91, which is other positions.

Those other position were basically totally undamaged, whereas the damage to the upper part of Lappberget was substantial. Then we have all the infrastructure in Garpenberg that was damaged, but not very severely.

What has happened now? Given the fact that we have all these 91 million tonnes left, but it's largely undeveloped, the most critical thing, the critical path for us is to get development going.

I'm very happy to say that as of last week, we had our first development explosives and the tunneling is now going on at full speed. We have gotten all power restored, we have pumping restored, we have ventilation restored, we have pumping water restored, we are able to do lots of things.

There's certain infrastructure, I would say also the workshops, by the way, are restored and working fully. There's some infrastructure linked to the paste infrastructure in the mine and also linked to the ore hoist and the personnel shaft that are still being repaired and will take another couple of weeks or a couple of months to get ready, but as I said, the critical path to get the development going has been passed.

Regarding the guidance for 2026, we had to give a very rough estimate that once we get up to production, we will produce roughly 100,000 tonnes per month. We're standing by that, we're going to be able to get only later in this quarter up to production, we have 100,000 in Q2, and then we have about 100,000 per month for the rest of the year.

If you add that up together with what we have already produced, you get around 1.5 million tonnes. The guidance for 2026 is right in line with what we had said before.

Now, we are now issuing two new pieces of guidance which I think are very important. Number one, we are saying that for 2032, we should reach full capacity, and full capacity is not just the 3.7 million tonnes that we had before this happened, but the 4.5 million tonnes that we had guided for the Capital Markets Day.

We will reach the higher production level in 2032 that we're going to do. We're also issuing that we're going to be able to get to about 2.3 million tonne, or just shy of 200,000 tonnes per month in 2027.

The developments are going ahead as expected, and actually faster than expected, we can get mining from the other ore bodies up to speed. In this plan, we have not put anything in Lappberget because the upper part of Lappberget is still very much unclear.

We have not been able to get our arms around, fully inspect, been able to think what we potentially can produce, and with what method, and at what cost can production be done. We have hopes that this is going to be able to get production out of there to some extent, and that's going to help us for the years 2028, '29, and '30, and so on, but that's still very much unclear, and we'll get back to that once we've been able to get our arms around the Lappberget situation.

That's hopefully giving you somewhat of a good understanding of where we're standing on Garpenberg. If you look at our other projects, I already alluded to Odda.

We're happy to announce that we had first production, even though it was on the last day of the quarter, we got some little production in there. We've had some teething problems during April to get this one up to speed.

We've had to change some elements in a boiler, we've had some pumps, and we've had also some other smaller issues that needed to be changed. As we're speaking right now, it is up and running again.

We haven't produced much in April. Hopefully, we'll get up to speed and have good production in May, and then in June going forward.

The other projects, the Rönnskär tank house is progressing very well. We're still, just as we had said on the Capital Markets Day, we're aiming for a start in Q4 of this year.

Boliden sand recycling project, very much running forward on track. On Garpenberg, the expansion with the new shaft, that project is also, although it's very early days, moving ahead, and we do not see that that will be impacted by the seismic events.

We should be able to pursue that project according to the original plan. On the ESG side, I'm happy to announce and the positive development here is that we're going down in the sick leave and we're about to hit pre-COVID levels finally, after having been way above that for a while.

Sick level is really going the right direction. The LTI frequency is we've had a little bit of a setback in the quarter.

Now, the numbers are still quite much lower than they were if you go back a couple of years, but we're slightly worse than we were the same quarter last year. On the greenhouse gas effect, it might look silly here as it looks like we're increasing it, but here you have to remember that we have not restated the numbers for the Lundin acquisition.

If you do that separation, we're very much in on our plans for our decarbonization program. Market side.

The market side has of course been what has been really pushing us up in the last couple of quarters. You can see here from the graph that the metal prices have gone up, and even though they peaked a little bit early in the quarter, and they came off a little bit during the quarter, it's still on a very high level.

At the same time, you can also see down there that as the metal prices tapered off a little bit, we actually got some positive push again from the currencies in there. We also have relatively weak TCs, although TCs is getting less and less important as part of the revenue mix for a smelter.

We also see byproducts, especially sulfuric acid prices, growing on spot. We have a contract portfolio that doesn't really contain any spot on sulfuric acid prices, we haven't really seen the uptick yet, but if these levels continue to be on this levels as we see them today, of course that will slowly also get into our longer term pricing that we have.

If you start looking into the outside world and where we're standing, you can see that copper prices have remained on a relatively high level, actually going up a little bit here lately. You can also see that the margins for copper mines in the world are actually very large, and it looks like every copper mine in the world is good at getting cost out.

This is, of course, not quite true because the reason for the cost reduction is very much linked to the high gold prices that comes as a negative to the cost level. The same thing on the zinc price.

You can also see there that the price levels stabilized on a decent level. Costs are coming down very quickly.

This has to do with the silver content in the mine that comes in as a negative cost. If you look at our production, I would say that Aitik is producing more or less according to plan.

We've had a winter quarter and then still working through the diorite issues. The grades are relatively low, but we are unchanging the guidance for the year.

We still expect higher grades to come later in this year. What you don't really see in the picture here, but we just want to make the point is that, after having had a couple of years of quite low stripping development, we have been able to push the stripping quite a lot already in previous quarters.

In this latest quarter, it was another very strong mine production quarter in the sense of lots of stripping going on, which we felt very good about. Garpenberg, we've spoken quite a lot about.

I think that we don't have to say much more about that right now. In Kevitsa, stable and reliable production.

It's been a good production quarter. Here, the grades are picking up, according to exactly what we have also guided.

Also very happy that recoveries are also going up in Kevitsa. That is sometimes actually related to the higher grades.

Somincor, despite the fact that we've lost, as we've spoken about before, we lost a week in the mill due to very heavy rain, we managed to keep on producing in the mine, and we've caught up maybe some of that already in the quarter, and the rest we will catch up during the rest of the year. We had a very stable production and a good production coming from Somincor.

Zinkgruvan, where we're standing today, also had good and high milled volume. Tara, slightly below expectations, but still in a ramp-up phase, and we still feel relatively good about that.

On the smelter side, also good production quarter. Improved process stability in Rönnskär, increased silver production coming out of intermediate products, which has helped us.

Harjavalta, also stable production, copper cathodes coming out in a good way. We have slightly lower nickel production due to feed mix where we've had to add pyrite to get the energy balance right.

Kokkola, strong production, generally speaking. Bergsöe, small unit, but very strong and stable production.

Odda, we've spoken about a little bit. We had the first feed in the quarter, but we have not been able to speed that up and get it into meaningful production numbers.

With that, Håkan, I'll leave it to you and talk a little bit about the numbers.

Håkan Gabrielsson

Thank you, Mikael, and good morning. As Mikael said, we had a good quarter.

We deliver an operating profit excluding process inventory of 4.4 billion, which is actually one of the better quarters we have had. Free cash flow at 1.7 and earnings per share of 13.45.

All in all, a good quarter. Looking by business area, you can see that both Mines and Smelters are roughly on par with the profits from Q4.

Mines is on par with Q4 in spite of of a hit from the Garpenberg event of about 1.1 billion. Smelters is on par with Q4 in spite of Q4 being being positively impacted by a one-off in in Rönnskär of 400 million.

All in all, a strong underlying performance in both business areas. Internal profits roughly 0 in the quarter.

Looking at the EBIT bridge year-on-year, comparing to to Q1 of last year, as you can see, we are helped by stronger prices, close to 1.8 billion positive impact there. That's, of course, mainly a result of the strong development of of metal prices that we've seen.

Metal prices alone contributes by more than 3 billion. It's mainly gold, silver, but also copper.

Then on the negative side, you have currencies and a little bit of TCs that adds up to 1.8 in total. Volumes are higher, and this number is explained entirely by the acquisitions of the two two mines from in in Zinkgruvan and Somincor.

Then on top of that, you have a negative impact from from Garpenberg, which is then offset by positives in other operations. Same thing with costs, that number is entirely explained by adding two two new mines.

Comparing excluding those new mines and comparing apples to apples, costs are more or less exactly flat. We we see an inflation roughly at 0 and good cost control in the operations.

Then you're aware of the one-off that we've had here, and that's the the write-down in in Garpenberg of 700 million. Comparing sequentially, again, very strong development in prices, positive 1.3.

It's basically across the line for most metals, but with gold and silver being the main contributors. I should also say that the the provisional and the definitive pricing of of contracts that were open at at last quarter end, December 31, contributed by about 450 million.

I think those of you that are modeling it in detail would have that number in there. Volumes, a negative impact, mainly as a result of the Garpenberg seismic incident.

Then Q4 or or costs are significantly better than than the fourth quarter. The fourth quarter was an expensive quarter, typically is.

We had a lot of contractors and external services, and also, as we had a good run of prices towards the end of last year, we had to adjust provisions for profit sharing and similar, which which weighed on the cost in in Q4. Good cost control.

Moving on to cash flow. We talked about earnings, we talked about the CapEx, Mikael did.

I'm happy about the the working capital side. Typically, we tie about 1.5 billion in in Q1.

Q1 is normally a weak quarter for working capital, and and this time we're roughly flat in in spite of stronger prices. It's good work in the smelting divisions behind this, working with working capital, working with inventory reductions, and then also a little bit impact from from the situation in in Garpenberg.

Another thing that stands out here is is is the tax side. Again, we had a good run of prices towards the later part of next year, and we've we've been catching up in in tax payments.

There's always a delay there, but you see it's a significant amount paid in in in Q1. All in all, this leads to a strong balance sheet, net debt to equity of 18%, payment capacity of close to 22 billion, and and, all in all, a strong balance sheet.

With that, Mikael, you want to continue with the outlook?

Mikael Staffas

Thank you, Håkan. Regarding the outlook, it's easy to say first that regarding guidance for everything except Garpenberg, we have no changes.

It's all the same guidance for the full year as we had before. That's also true for CapEx levels, and so on.

Just to repeat regarding Garpenberg, we are now guiding for 1.5 million tonnes in 2026, that is roughly a run rate of 100,000 tonnes or so per month for the last 7 months of this year, and then adding on the production that we've had already in Q1. Very much in line with the very preliminary guidance that we issued in connection with the profit warning once we had the seismic event.

Regarding then 2027, we have a new guidance that has not been issued that is basically doubling production from the 100,000 tonnes per month pace to almost 200,000 tonne per month or 2.3 million tonnes for the full year of 2027. Then we are now also guiding that in 2032, we should be up to the new estimated full production of 4.5 million tonnes, which is then clearly above what we producing before the seismic event at 3.7 million tonnes.

Also grades are the same. The grade for Garpenberg for this year has changed slightly, slightly lower zinc and slightly higher silver as a consequence of other position being mined than the Lappberget positions.

We're also here just very clarifying that we are guiding for the maintenance impact in smelters where the big chunk of the maintenance for 2026 will come into Q2 or 350 million SEK. With that, operator, I think we're ready for questions.

If you wish to ask a question, please dial pound key 5 on your telephone keypad to enter the queue. If you wish to withdraw your question, please dial pound key 6 on your telephone keypad.

The next question comes from Adrian Gilani from ABG Sundal Collier. Please go ahead.

Adrian Gilani

Yes, hello, and good morning. My first question is on the 2027 guidance in Garpenberg.

Just to clarify in that guidance, is it included that you also expect to reach a run rate of 3.7 million tonnes at some point during the year, or do you expect to be below nameplate capacity for all of 2027?

Mikael Staffas

We will expect to be below nameplate capacity for all of 2027.

Adrian Gilani

Understood. I guess also a question, you talked shortly about acid prices and not having any spot exposure.

Can you talk a bit about how that contract portfolio is structured and when you will see a P&L effect if the high prices were to remain? Is this something that should boost earnings in Q2 already?

Mikael Staffas

Most likely not so much in Q2, but for the second half of the year it would. We have a portfolio which is a little bit complex and combines all kind of length of contracts, and they have longer contracts with adjustments that are kind of slower to spot prices, and so on.

If the current spot prices were hold on, we will see some meaningful effect in the second half of the year.

Adrian Gilani

Okay. Just a follow-up quickly.

Can you say roughly how much of the volume will be priced on current prices in the second half of the year? Is that possible to say?

Mikael Staffas

This is now when it gets really complex because, as there is one kind of European spot price and there's a global spot price. We have much bigger exposure to the European spot price than we have to the global spot price.

The European spot price increased already a little bit in '25, we had good byproducts there already, and it has not spiked as much as the global one in so far this quarter. That's the most important one to us.

I don't know, Håkan, if you have a number what it could be if that one were to stay. Then we have some that's on the kind of international, global spot price, but that's a relatively smaller part.

Håkan Gabrielsson

I don't have a number apart from the fact that it's less than 20% that is exposed to the global spot. Most is European levels.

Adrian Gilani

Okay. That's very helpful.

Thank you. That's all for me.

Operator

The next question comes from Alain Gabriel from Morgan Stanley. Please go ahead.

Alain Gabriel

Good morning. Thank you for taking my questions.

Again on Garpenberg, you've given the guidance for grades for the average for '27. How should we think about the sequencing of the grades for both zinc and silver over the course of the year and into '27?

That's one. Then two, on the run rate you've given for next year, the 2.3 million tonnes, if I may interpret your comments suggesting that there's a wide range of outcomes, how should we think about the bottom and the upper end of that range, and what needs to happen for you to meet the bottom or the upper end of the range for '27 mill throughput?

Thank you.

Mikael Staffas

Just to clarify on that, and it has to do with the Lappberget ore body, we do not at presently expect to be able to mine anything at all from Lappberget in '26 or '27. We have not yet been able to conclude that investigation.

We have hopes that we can mine something coming to '28 and beyond. The 2.3 that you've seen is then based on no Lappberget.

Of course, there's a potential upside if we were to be able to produce out of Lappberget, but we do not think that we will, even though we do not know. I think that the 2.3 is based upon getting access to Kaspersbo, Huvudmalmen, and more positions in Dammsjön and Kvarnberget with relatively little risk.

We would feel pretty good about the 2.3. We have not guided formally for grades for 20 2027.

They are similar to the grade for 2026. Regarding sequencing, no comment really on that.

We tend to avoid to guide on grades for the individual quarters.

Alain Gabriel

Thank you. A follow-up on that as well on the flow of material from Garpenberg into your smelting system.

Do you expect some disruptions, and how do you plan to mitigate this disruption, if you can give us some financial indications of what we should be expecting as a fallout from the concentrate shipment disruption? Thank you.

Mikael Staffas

I think that the financial implications are relatively small. There are two potential issues.

There is very little risk that we will not get zinc units so we cannot produce. That would cause a zero.

We have already basically procured zinc enough to be able to mitigate Garpenberg. There is a little bit of a financial impact that of course when we procure something now, we have to buy it at spot terms, and of course spot TC terms are not that good right now, there is a little bit of a financial impact from that.

There is a second financial impact which is very much difficult to get your arms around, but it shouldn't be that big. As in zinc smelting, it's not just having the enough amount of concentrate, you're very dependent on making sure that you can get the right recipe to be able to feed it well through the smelters.

Losing Garpenberg, which is a very good and a very useful ingredient, makes it difficult to replicate the recipes, which might impact a little bit on throughput, availability, and so on, and some of the performance in the smelters, but we don't think it's going to be a major financial impact.

Alain Gabriel

Thank you very much. Thank you.

Operator

The next question comes from Liam Fitzpatrick from Deutsche Bank. Please go ahead.

Liam Fitzpatrick

Good morning, Mikael and Håkan. A few questions on Garpenberg.

The first one, just to step back a bit, can you just explain in a bit more detail what you mean by substantial damage to Lappberget, just to give us an idea of the challenges you're facing? The second question is just around how high production can get through other areas if you can't re-access that part of the ore body.

Is 2.3 million tonnes sort of about the limit, or could you push that higher before the second hoist or the new hoist comes in? Then, what you haven't told us is sort of additional CapEx for the development work to open up the new areas.

Is that expected to be substantial? Will that have some impact on 2027 CapEx?

Thank you.

Mikael Staffas

If we start from the back, CapEx relatively not so substantial. I think it's part of the more normal developments.

On Lappberget, and just have a sense of what has happened, and this is of course very much oversimplifying things, but you can imagine that Lappberget, which is kind of 300 m wide, 150 m thick, and kind of from 1,100 up to 400, 700 m height, without going into kind of any detail, I would say that this thing has fallen down 5 m. The whole thing has fallen down 5 m.

What's the challenge with that? Of course, all the kind of development that we had done in the ore doesn't match the developments on the outside.

That might be the simpler thing to kind of fix if that would be the only problem to get that have to happen. The much more challenging thing is that when this has happened, how has the ore body cracked?

If this has just kind of moved down, you could imagine going into the ore body and keep on mining the way it was mined before. It would be very easy.

Most likely, it has cracked. Not uniformly in the same part, but it has cracked in different pieces, and where it's cracked a lot, it might be impossible to go in, because as you start going in and try to tunnel things, you'll just get rock fall over you.

It will be unsafe to do that. In other areas, it might be possible.

It might be possible with smaller dimensions. It might be possible if you mine slower.

These are all the issues that need to be answered. Then on top of that, there is a kind of another challenge.

The Garpenberg mine has quite a lot of water into it, and as this kind of thing has fallen down, there is also the need to make sure that we control the water levels within the ore body. With the new cracks and everything else, we might have a different level of water and a different way for water to go through, and that also needs to be investigated thoroughly so you understand what it is.

Therefore, coming back to what I said, we think this is going to take months until we kind of have our arms around what can really be done. We think it's not going to be easy.

We hope that we're going to be able to mine, but as we said before, we don't think that we can mine anything in 2026 or 2027, the 2.3 that we have guided for should be fine. We should also, even without Lappberget, be able to gradually step up in 20 2028 and 2029, but it might be that they will be not stepping up so much if we don't get Lappberget in until we get the new hoist in '32.

Liam Fitzpatrick

That's very helpful. Just a quick follow-up on seismic activity.

Is it kind of back to normal, or are you still experiencing abnormal

Mikael Staffas

It's back to normal. After the 48 hour of roller coaster, if you want to use that word, it's basically been back to normal since.

There is no increased seismic activity at the moment.

Liam Fitzpatrick

Okay. Thank you.

Operator

The next question comes from Marina Calero from RBC Capital Markets. Please go ahead.

Marina Calero

Good morning, and thanks for the call. I have a couple of questions.

One follow-up on Garpenberg: when do you think you'll be in a position to announce the market the extent that you can recover mining at Lappberget ore body? Then my second question is on inflation.

You've had very good cost control so far. Given the ongoing conflict in the Middle East, do you expect any inflationary pressures in the second half of the year?

Mikael Staffas

I heard you a little bit poorly, but if I understood you right, your first question was about Garpenberg and about Lappberget and did I understand right, how we could mine that one? I didn't really understand the question, but I can repeat what I just said, hopefully answering your question, that Lappberget, it will not be mined exactly as we have historically mined it, I'm pretty sure, but that doesn't mean that it cannot be mined.

It might have to be mined with a smaller, more small-scale type of mining method, and it might mean that we might need to leave more pillars. There are lots of issues around that.

When will we know that? As I said, it will be months.

This is very difficult to push these kind of investigations. It will be towards the end of the year, hopefully we'll have some more feeling around the 2028 and beyond.

Regarding inflation, Håkan?

Håkan Gabrielsson

I think that's not an easy question. There is obviously a great deal of uncertainty, but we're obviously monitoring the development of oil prices and so on.

I guess that's if we get inflation, that's mainly connected to oil. We spend each quarter a bit more than 300 million on diesel and oil, any increases will have an impact on that.

On top of that, we have about 700 million spend which is chemicals, explosives, transport, and similar, not directly connected to oil, but with a significant impact, so that might also have an impact. Then, as a follow-on, an additional 700 roughly per quarter on electricity.

All that will depend on what happens in the Middle East, etc. We'll just have to monitor that.

Marina Calero

Okay. Thank you.

Operator

The next question comes from Amos Fletcher from Barclays. Please go ahead.

Amos Fletcher

Morning, gentlemen. A couple of questions.

I guess the first one was just to think about the EBIT bridge into Q2. Could you give us what the Garpenberg EBIT contribution was in Q1?

Let's see.

Håkan Gabrielsson

I think that Garpenberg had a contribution of about, let's see if I get this right, about 1.4, 1.5 billion in Q1. We'll lose a fair part of that gross profit.

As you saw, the 400 million impact that we talked about, that was just for the couple of weeks that the mine was closed. That will have an impact.

Then prices, we'll see what happens. Then on top of that, we'll have some maintenance in smelters.

I think those are the main components. Then Odda, we'll see how much impact we get of that.

Amos Fletcher

Okay. Then I just wanted to ask on the working capital side.

Can you give us any guidance for future quarters? Obviously, as you noted, Q1 was a very small build versus normal seasonal patterns.

Håkan Gabrielsson

I think typically Q2 is a quarter that is relatively flat on working capital. As Odda gets up to speed, we will tie a little bit.

It's not as much in a zinc smelter compared to, for example, a copper smelter, but I would expect a flat quarter with the exception of the build from Odda, which could be about half a billion or something like that.

Amos Fletcher

That's great. It's kind of related to Marina's earlier question on diesel.

I was just interested to know your purchasing positions. Obviously, it seems like there's very little effect realized in the financials for Q1.

Is that just the inventory positions that you hold, and I was just wondering how big that is, how many weeks that is, and when we might start to see higher prices flowing into the financials through Q2?

Håkan Gabrielsson

I don't have an exact number, but you're right. It's 1.5, 2 months of lag before the diesel hits the P&L because of the inventory positions that the material we've already bought.

So

Amos Fletcher

Great. Perfect.

That's all. Thank you very much.

Operator

The next question comes from Krishan Agarwal from Citigroup. Please go ahead.

Krishan Agarwal

Hi. Thanks a lot for taking my question.

Can I clarify that the guidance for 4.5 million tonnes for Garpenberg by 2032, does that include any of the mining happening into the Lappberget area?

Mikael Staffas

Sorry, does it include any of the what?

Håkan Gabrielsson

Lappberget.

Krishan Agarwal

In

Mikael Staffas

the 4.5, then we're into the new hoist and it doesn't contain any Lappberget.

Krishan Agarwal

Understood. Then the second question, more of a clarification, the Odda smelter ramp-up, is it on track for the Q4 full run rate?

Is that a fair assumption?

Mikael Staffas

I think it's still on track for a relatively full ramp-up rate. Of course, the challenge with running up a smelter is not really getting it, where exactly you get the last percentage.

We need to make sure that we get production going. As I said, as of right now when we're speaking, we're producing fully and it looks relatively good, it looks like these teething problems with the boiler and with the pumps that we've had seem to be now all working.

Does that mean that we will not find something else? Maybe something else will also show up in this ramp-up period, but we should clearly be able to ramp up during the next few months.

It shouldn't be that long.

Krishan Agarwal

Understood. The final question is on the tank house.

I remember you saying, okay, the tank house building you are doing is essentially a higher capacity than the earlier one. Would you be able to give us some kind of a sense as how much of the production you should expect after the commissioning of the tank house in the Q4 and probably full ramp-up in '27?

Now, the tank house that we're building has 230,000 tonne capacity, which is very much in line with the one that burned down. We are not increasing capacity because of this.

This means that if you combine the 100 230 with 170 that we have in Harjavalta, we will be slightly long tank house capacity. We are unlikely to buy anodes because of logistics and other things, the limiting factor is going to be our anode production and not the tank house going forward.

Krishan Agarwal

Understood. Thanks a lot.

The next question comes from Daniel Major from UBS. Please go ahead.

Daniel Major

Hi. Thanks for questions.

Just to follow up again on the Garpenberg kind of earnings bridge from Amos's question. Can you provide us a estimate of what split in the cost base is fixed versus variable?

If we look at 2025, your reported costs, defined as revenue less EBITDA, was about 2.1 billion krona. Can you just give us a sense of what the cost base will look like when you're running at a lower volume?

Håkan Gabrielsson

I can at least try. There is obviously some uncertainty still, but you're right.

We had, I think, about 550, 560 million SEK in the first quarter, it adds up to the number you gave for last year, just to confirm that. We typically consider about 30% to be variable, meaning energy, consumables, etc.

There will be some savings on that. However, we will use more resources for tunneling, not in the ore body, but to new ore bodies, and we'll have to decide whether that should be treated as CapEx or OpEx.

Then on top of that, there will be some repair costs. Without giving an exact number, 30% is variable, but I think you should treat the cost savings quite conservatively in your assumptions, because there is a lot to do to get this up and running again.

Daniel Major

Okay. That's clear, so much closer to the 550 than 550 less 30%, is that the right way of thinking about it?

The next question comes from Richard Hatch from Berenberg. Please go ahead.

Richard Hatch

Thanks for the call. Just a few questions.

Just firstly, just quickly on Tara. Just wondering if you can just give us a bit of a steer as to when you hit that 1.8 million tonne run rate.

Should we be expecting that to be occurring over the coming quarters or should we be going belated? That's the first one.

Then just the second one is just on grades at Garpenberg in '27. I don't think you've given guidance, but I was just wondering whether you would be able to give a direction of travel.

Then thirdly, just you mentioned that you're comfortable in obtaining zinc material for the smelters to offset the Garpenberg reduction in volumes, but can you just perhaps just give a bit more color around just what you're seeing in that zinc concentrate market, if you do see it tightening over the next couple of years, or if you feel comfortable that you're going to be able to secure the material you need while Garpenberg's off? Thanks.

Mikael Staffas

Tara, 1.8, we haven't changed the full-year guidance from 1.8, which means that we need to reach that level within the next few quarters to keep the full-year guidance. Grades '27, order of magnitude similar to '26, without going into detail.

Then zinc material, we don't see and we don't foresee there being any issues in finding the zinc material. It's a matter of cost, and where the spot TCs will develop on zinc, I think your guess is as good as mine.

Richard Hatch

Okay. Mikael, can I just push you a bit on Tara?

Your run rate currently well below that 1.8, right? What are the challenges, the bottlenecks?

Where are you sort of seeing the areas to improve and get to the level you want to get to?

Mikael Staffas

It has been developments. We have not been able to keep developments up to the level we need.

We have done efforts to increase developments. They have not given quite the effect that we wanted, but they've given some effects, developments are coming, and we're working hard with developments also now in this quarter.

As I alluded to before, we've actually sent some crews from Garpenberg over to work with developments in Tara as Garpenberg's been down.

Richard Hatch

Okay. Very helpful.

Thanks.

The next question comes from Boris Bourdet from Kepler Cheuvreux. Please go ahead.

Boris Bourdet

Hi. Good morning, and thank you for taking my question.

The first one is on Garpenberg, about the seismic activity now that you have more insight into what happened. Can you say whether that was linked to the mining operations, this rock fall, or whether it was connected to external seismic activity?

I'm asking the question because recently we had a medium magnitude seismic activity in Norway and Sweden, on the western part of Sweden. The second question is on Aitik grade.

We see the grades are further going down. What makes you comfortable that the grades will go up in H2?

Thanks.

Mikael Staffas

Aitik grade, I think we were very clear in our early communication that the first half would be lower and the second half would be higher when we communicated the 0.18. We have better positions that we're coming into in the second half of the year with higher grades.

Garpenberg, this is of course something that we cannot definitely say why, and that's part of the investigation why this happened. I think it's fair to say that it's because of our mining.

This is an area that is quite seismically stable and should not normally have seismic activity, but maybe theoretically there was also an outside event that triggered this thing, but that we do not know, and we can absolutely not say for sure. I think it's more likely that this has been triggered by our own activities.

Of course, we need to take the learnings from that to make sure that this doesn't happen again on this scale. As I said, this is very early days and the investigations are still ongoing to both why this triggered and why it triggered in the way that once it triggered, why it continued the way that it did.

Boris Bourdet

Thank you. Maybe just to follow up on Garpenberg, if I get you right, there is no specific additional costs or CapEx, or no significant amounts to be expected on top of the already impaired 700 and the missed volumes, or should we expect additional things?

Mikael Staffas

I think Håkan said that there will be some repair costs, but those repair costs might be more seen as not getting down the operating cost for operating only at 30%. I think that that's more the way to see it.

I don't think there will be any increased costs as such, but maybe not quite as much lower as you would have expected otherwise. We don't see any additional needs for write-downs or so on.

Boris Bourdet

Thank you.

The next question comes from Pavel Kirjanovs from Bank of America. Please go ahead.

Pavel Kirjanovs

Good morning, gentlemen. Thank you for the call and presentation.

I just had another one on Garpenberg, and apologies if this was asked previously, but as we think about Garpenberg through 2032, what would allow you to reach that earlier potentially?

Mikael Staffas

I would say that the way to reach it earlier, and the only way to reach it earlier would be that we would get significant mining coming in Lappberget, because we will not be able to develop the other ore bodies any faster. This is in line with the development pace that we have.

It will be that will be dependent on getting mining and some meaningful mining out of Lappberget. Just to make sure again, we do not in any way promise that.

We do not know. We hope, but we do not know the situation in Lappberget.

Pavel Kirjanovs

Understood. Thank you.

As a reminder, if you wish to ask a question, please dial pound key 5 on your telephone keypad. The next question comes from Daniel Major from UBS.

Please go ahead.

Daniel Major

Hi. Thanks.

A couple of follow-ups, if I may. Just on the depreciation line, I'm assuming this quarter the 700 million write-down at Garpenberg went through here, but can you just provide us a guidance level on the quarterly run rate of D&A across the group following the changes at Garpenberg?

Then a second follow-up, I've asked many times before, but why do you focus on EBIT, not EBITDA, when all of your peers focus on EBITDA?

Håkan Gabrielsson

Let's see, the depreciation, then. We take out 700 from the asset base, which is depreciated over quite a long time, if you just spread it across the lifespan of those, that's mainly developments, so that is a fairly limited change in depreciation.

What will happen, though, is that when Odda gets up to speed, we will increase the depreciation there, as we talked about earlier. Also a reminder is that Aitik is largely depreciating based on metal value produced, also the depreciations in Aitik will increase.

Regarding EBITDA and EBIT, well, I don't really have any specific comments on that. I'm aware that many people focus on EBITDA.

We're working with EBIT excluding process inventories, and then I think it's easy to get the EBITDA number as well. I guess we might have to think about that, but until further notice, we're sticking to our regular follow-up.

Daniel Major

Håkan. Just to push you on that slightly, what would be a sensible run rate with those moving parts on depreciation through quarterly basis through the remainder of the year?

Håkan Gabrielsson

Let's see now. I think that we're going up in Odda from about 200, 300 to about 800 per year.

That will be the change there. Aitik, it's not so much this year, but as we go over the next few years and getting closer to higher grade areas, that would be fairly significant numbers, but it all depends on what exact year you're looking at.

For Odda, it's about 200-something to 800-something.

Daniel Major

Per year.

Håkan Gabrielsson

Per year.

Daniel Major

Right. Quarterly through the remainder of this year?

Håkan Gabrielsson

About 150 1 150 or 200. Then

Mikael Staffas

slightly lower because of the 700, but that's maybe 50 comes out or something like that.

Håkan Gabrielsson

I'd say less because it's quite long depreciation times on those assets.

Daniel Major

Right. We should take the base, which is this quarter less 700 million, and then add those variables on, is that the right way of thinking about it?

Håkan Gabrielsson

Add about 1 150, 175 per quarter, then I think you should be fairly spot-on.

Daniel Major

Versus this quarter less 700.

Mikael Staffas

Yes.

Daniel Major

Okay. Thanks.

Just one other follow-up, if I could, just a clarification that you mentioned earlier. Did you say that the net provisional pricing impact was a positive 450 million this quarter, total?

Håkan Gabrielsson

Depends what you mean by net, but the value in the Q1 profit that came out of preliminary price volumes at the end of Q4 and that was then definitively priced in Q1, that was 450. If you refer to the EBIT bridge, you'll have to compare what we had for what the impact was in the respective quarter prior.

The impact on this P&L was 450 this quarter.

Daniel Major

Okay. All right.

Thank you.

The next question comes from Liam Fitzpatrick from Deutsche Bank. Please go ahead.

Liam Fitzpatrick

Hi, a couple of quick follow-ups on the numbers as well. Just on that 1.4 billion number that you gave us, Håkan, for Garpenberg, I assume that's before the impairment.

I just wanted to confirm that. Then, you kind of suggested that you're still not entirely certain or clear in terms of how you're going to classify between OpEx and CapEx at Garpenberg in terms of the additional development work.

In terms of what you're sort of guiding to us at the moment, are you assuming that most of this sort of additional tunneling work and so on is flowing through OpEx, or is it sort of split, or how should we think about it? Thank you.

Håkan Gabrielsson

Now, when we say that be conservative on your estimates of OpEx, that we will not be able to save that much on OpEx, that's based on the fact that we'll still have to do the tunneling. Then if we decide to classify some of it as CapEx, then you would see slightly lower OpEx and slightly higher CapEx, but I think we're talking about 100 or 200 million Swedish order of magnitude.

What we've said today is basically based on that being mainly OpEx. Normally, when we develop towards a new ore body, that would be CapEx, we'll just have to come back on that.

It's relatively small numbers anyway. Okay.

Liam Fitzpatrick

Garpenberg, the 1.4, is that pre the impairment?

Håkan Gabrielsson

Yes.

Liam Fitzpatrick

Yes. Thank you.
