Hello, everyone and welcome to TSA's Earnings Conference for the Fourth Quarter and Full Year 2023. Thank you for joining us. I'm Vicente Ferreira, Head of Investor Relations. Today we'll share our highlights on video and then we'll begin our live Q&A session with our CEO, Alberto Griselli; and our CFO, Andrea Viegas. Before we can discuss our results, annual guidance, I remind you that management may make and this presentation may contain forward-looking statements. So please refer to the disclaimer on the screen which will also be available in our earnings materials and our investor relation website. With that we move to our results.

Hi to everyone. I'm Alberto Griselli, CEO of TIM in Brazil. I'm very pleased that 2023 was an outstanding year with great achievements and record high results. As we explained during our Investor Day in November, the Brazilian mobile market is healthier than ever, supporting a more for more strategy. New market dynamics and favorable demand are driving our results to improve across the board. Our service revenues grew in 2023 10.7% year-on-year, totalling more than BRL23 billion. With costs under control, our EBITDA grew more than 14% to reach the highest number in our history, BRL11.7 billion. In this context, our 2023 margin expanded to almost 49%, the highest among the large telco in Brazil and Latin America. Another metric that measures our efficiency in allocating resources is the CapEx to sale ratio. We closed 2023 with the best result ever, just below 19%, contributing to our operating free cash flow growing more than 58% year-on-year, summing to BRL4.2 billion. To complete this small summary, our net income rose to BRL2.7 billion after expanding more than 50% year-over-year. These results explain why we were confident in November in raising our shareholder remuneration target to BRL2.9 billion. To generate such strong numbers, we are developing the best value proposition based on the BBB strategy, Best Service, Best Network and Best Offer. During 2023 we worked extensively to deliver improvements in customer experience. We seek the best service by digitalizing the interaction to accelerate and improve demand resolution. And we are best-in-class in all resolution rankings of Brazil. At the same time, if a human attendant services a client, the satisfaction with this interaction must be best-in-class and we can deliver that. Call center [MPS] (ph) improved more than 40% in the fourth quarter. Meanwhile, we are consolidating our leadership in…

Hello to all. I'm Andrea Viegas, CFO of TIM in Brazil. To reach some numbers and go above our original target for 2023, we closed the year at an excellent pace. In the fourth quarter, sales and revenue grew more than 7% year-on-year, with mobile raising 7.6%, while broadband spanned at 9.5%. With costs under control and reaping the benefits of the M&A transaction, our EBITDA grew in the quarter by 7.5% to reach BRL3.2 billion, with the margin expanding to 50.2%. Accounting for the leases, EBITDA after lease grew even faster at a 15% pace, amounting to BRL2.5 billion. This performance benefits massively from the sharp execution of our decommissioned projects. We ended the year with 4.4 thousand sites decommissioned and 3.8 with contracts canceled. As a consequence of a better depreciation number due to lease reduction and the tax shield generated by the interest on capital, our net income presents a robust expansion of more than 50% year-over-year. With this, net profits reached one of the highest results in TIM's history, summing BRM900 million in the fourth quarter. Additionally, we saw a vigorous cash generation in the fourth quarter, with operation free cash flow growing more than 50% year-over-year and margin expanding to nearly 19%. For the full year, EBITDA after lease and minus CapEx over revenues stood close to 18%. With a strong cash position, our net debt fell to BRL11.6 billion, taking our leverage ratio to one-time EBITDA. All those numbers confirm what a remarkable year we had in 2023. To wrap up this results discussion, I hand it back to Alberto.

When we started the year, we set challenging, but achievable targets. As we executed our plan, results began to come faster, which led to the best performance of TIM's history in many KPIs. We completed a 1/4 of a century of existence over delivering on every front. We set ourselves to grow high single-digit in service revenue and deliver double digit, proving our ability to operate multiple revenue levers. We forecasted low double-digit growth for EBITDA and closed 2023 with mid ends showing significant operational leverage. Our CapEx on revenue was expected to go just below 20%. We delivered below 19% with the best coverage and largest mobile network in Brazil. This is a clear demonstration that we are improving our capital allocation strategy. The expectation for operating free cash flow was double-digit growth, and we delivered close to 60% expansion. We initially pointed to BRL2.3 billion for shareholder remuneration but we decided to raise our target in November to more than EUR2.9 billion and delivered on that. These notable achievements have been made possible by the contribution of every TIM employee, and I'm proud to lead the team of committed and hard-working colleagues with an engagement level of above 90%. 2023 was an outstanding year, but we are already in 2024 and on a long journey to become the most preferred telco. We are updating our guidance to adjust to new market conditions in the macro environment. Service revenues are expected to grow above inflation and not faster than last year's plan. EBITDA is forecasted to sustain a solid growth pace with a positive margin contribution. Nominal CapEx should remain broadly stable with a clear focus on developing infrastructure to drive revenue growth. For operating free cash flow, we confirm the growth pace we set during the old plan. On March 7th, the TIM Group will host the Capital Market Day in Italy. We plan to disclose an updated target for shareholder remuneration there, among other elements that complement our strategic plan. Please join us in this event that will set the direction of a new TIM Group. Now let's move to the live Q&A session.

Thank you, Mr. Alberto. We are now going to start the question-answer session. [Operator Instructions] Our first question comes from Marcelo Santos from JPMorgan. Mr. Marcelo, your microphone is open.

Hi. Thank you allowing us to ask question. Thank you for the presentation. My first question is regarding the sources of growth going forward in mobile revenues. In the past couple of years, in general, TIM didn't add so much volume and a lot of the revenue growth came from ARPU side. Is this something expected to continue in the coming years? Or should we see more growth on the volume side and a little bit less on ARPU? Just wanted to see your thoughts there. And the second question is regarding the pricing environment. How do you see that for 2024? Thank you.

Okay. Thank you, Marcelo, so let me address the two questions. So, when we look at the revenue growth dynamic, we've got a number of different levers in our hands. So, you got the volume, you've got the more-for-more strategy, and you also have the inter-plan migration that we carry out in our customer base, meaning free to control-to-control and control to postpaid. So, when you look at the way we want to move forward is basically a mixture of all these elements. So, when you say that we focus more on ARPU versus volume, it depends a bit on which temporary horizon you're looking at. So, if you look at the performance for postpaid after the [indiscernible] migration that ended in the first quarter last year, you would see that our postpaid growth quarter-on-quarter, it's difficult to see still year-on-year. It's basically driven by the composition and the blending of all these three levers. So, we are growing in volumes. We are growing because of the more-for-more strategy, and then I will go into the second question. And we are growing impacting the ARPU basically by migrating customers to better plan where they have the right benefits for the price that they're paying for. So, looking forward, I see in postpaid, a combination of all these three levers. In prepaid, the situation is a bit different because basically, the market is sort of evenly divided by the three operators. And therefore, I think that the price lever is going to be more predominant for that specific segment. So, when you go then to the competitive dynamics and what we are expecting to do in terms of pricing, basically, the main message is following. The competitive dynamics remain quite rational. And if we look at what we did in 2023, it's something that we want to do in 2024. So just recapping what happened last year. Last year, in the second quarter, we applied our more-for-more strategy for postpaid, both on what we call front book and back book prices. So, this happened in the second quarter last year. And by the end of last year, we decided to upgrade our prepaid offer. So, what we are going to do this year is what we intend to do this year is roughly similar. So, in the second quarter this year, we are going to upgrade our front book and back book prices for postpaid. This has already been decided and it's being coded in our IT systems. The decision has not been taken yet for prepaid. We just did a move recently. So, we need to see what the customer reaction is, what the competitors' reaction is and then made a final decision. But the plan that we're looking for is to do some further adjustment by the end of this year. So basically, at the same timing we did it last year.

Thank you. And what about control?

When I say postpaid, it's pure postpaid and control. So, we're going to do the two things together in the second quarter, as we did last year. And it's going to be inflation plus on a more-for-more strategy. Just adding a bit more on that, you know that we provide extra benefits to our customers where we do these movements. So, it's going to happen in the second quarter this year for control and postpaid exactly as it happened last year in the second quarter.

Perfect. Thank you very much.

Our next question comes from Leonardo Olmos from UBS. Please Mr. Leonardo, your microphone is open.

Hi. Good morning, everyone. First of all, congratulations on beating the guidance. It was very positive. So, I've got a couple of questions here. The first one is a double-click on Marcello's question on mobile. Where do you see the most opportunities to better monetize your plan? So, we heard you and competitors talking a lot about prepaid and social media having unlimited data allowance and maybe cross-selling with other subscriptions. Where do you see the opportunities in terms of products and how the packaging of your plans could be done in 2024? That's my first question. I'll do the other after you answer.

Okay. So, Leonardo, thanks for your nice comments at the beginning of your question. So, if you look at what we shared at the Investor Day in November, basically is that we see favorable conditions on the demand side. So, if you look at demand, and this is across the board, across all plans. Basically, we see an essential services that is a sort of cheap and utilization use is fairly low, especially in prepaid and control. So, there is actual opportunity to implement the more-for-more strategy. So, the more-for-more strategy, it's a combination of a number of elements. And I think that basically, it's an extra data allowance, especially for lower-end plans, so prepaid and control because there is a limited use still compared to other markets. And so, there is the opportunity to monetize that. And then there is another set of services that is related to the digital life of our customers that we are constantly including into our portfolio. And then there is the final item, which is OTT, which I will address as the last one. So, the more-for-more strategy in terms of increased data allowance, this is what we have been doing over the last years. And I think we will keep on doing this going forward across the board. Even because when you look at prepaid and postpaid, we need to maintain a coherence of the plans among themselves. So, if we move something, we need to upgrade the other side of it. So, if we move control then, we need to upgrade prepaid to have the right incentives than to move customers from one plan to the other one. So, the more-for-more strategy on data usage is fairly unchanged. Then what we are doing with success is to providing extra benefits to…

Perfect, Alberto. that was the point of my question. Happy to hear about the timing of the ZÃ Delivery promotions since we're so close to Carnival. My second question, if I may about leasing, a very positive surprise on the numbers, 7% below our figures. The cash generation was way above what we expected. But when we look at 2024, what's your expectations on decommissioning? And how can we consolidate that with the 5G increase in coverage? Thanks.

Okay. I will ask Andrea to address this first, and then -- let me start with more general comments on the lease. So, when you look at the leases, you've got a number of plus and minus effects. And if you look at the decommissioning exercise, this is a sort of a one-off exercise, right? And we got the towers and the Kempen from OI, we have been decommissioning at a quite fast pace, what was not useful to us. At the same time, you have contractual adjustment of the cost base because part of this cost needs to be adjusted by inflation, basically. And you have an increased footprint. So, we reached all municipalities with 4G. But nonetheless, especially in B2B and some kind of obligation, we need to put more site on the ground. And so, our footprint increases over time. And then as you correctly mentioned, you got 5G also. So, the effect of 5G is that we need to put in additional antennas on our towers, depending on the contract, this is additional wind space and so additional costs at the end of the day. And then there are potential minuses that we been discussing in the Investor Day, which are related to the fact that we have ongoing initiatives to optimize this cost from technical innovation to negotiation with our partners so that our companies. We got the 4G round-sharing agreement with Vivo that has been reactivated, let's put this way, that, of course, reduce resources. And so, you've got all this set of movements, some are positive and some are negative. Of course, what we want to ensure is the sustainability of this cost line over time as we increase our footprint and deploying technology to improve the quality of service to our customers. And so, we've got all these initiatives that basically we are putting in place to compensate or to partially compensate for the cost pressure that we have either for price adjustment either for increased footprint on our network. Of course, the lower inflation is something that is positive going forward because it's been negative or fairly negative over the last years looking more positive year to go. And so basically, what we want to have is delivering in our hands to ensure the sustainability and the optimization of the cost line. That's why we've got a robust plan in place. I will ask Andrea to elaborate on the commissioning plan it's going quite well.

Alberto almost said everything, but related to the decommission in the fiscal terms, we finished. So, we have very good results in this quarter. We will continue to have some good results in the first quarter. But as Alberto mentioned, we have the price adjustment. In February and March, we have the huge impact of this price adjustment. And also, 5G although not necessarily generates new sites, we have to occupy more space on the site. So, we have some kind of adjustment in these expenses. But what we expect from now on is to continue to look for another ways of gain productivity in the lease sites. The lease side of our negotiation vessels with the major contracts that we will still have.

Very interesting. Okay, thank you very much Alberto, Andrea, Vicente and [indiscernible]. Have a great day.

Our next question comes from Fred Mendes from Bank of America. Please Mr. Mendes, your microphone is open.

Hello. Good morning, everyone and thanks for the call. I have two questions here as well. The first one is on CapEx, especially on the guidance, it was slightly above where we had, I guess, we are on the bullish front. But just trying to understand if there is like a line, you're going to be focusing more, let's say, IT or 5G that could eventually explain this, let's say, higher CapEx at least from our expectation or if that's basically network improvement, basically business as usual. This will be the first one. And then the second one, if you can just comment Alberto, how is going to be the structure that now the Leonardo went to TI, if you continue to help on the operations from there, you going to have a new structure? Anything you can comment on that. I think it would be great for us.

Okay. Let me take the second one, and then I will ask Andrea to discuss a bit about CapEx. So, when it comes to the structure of CTO, the CTO structure is being removed. And so basically, this is something that has happened. I think it was either last year or the beginning of this year. I don't remember more. But basically, what happened is that Marco DiCostanzo, and was the former Chief Technology Officer and Awana Matar, which was the former Chief Information Officer are now reporting directly to me. So, these are two executives that have been with us for many, many years. And this structure has been basically a move from one report to report. Our strategy doesn't change as a result of that, of course, so we've got a full continuity and so our focus is always in terms of correct capital allocation and leadership in network quality of service. And when it comes to the IT, it's innovation and strong support on our go-to-market. So, this has been already done, Fred. And the executives that have been promoted has been with us for, I think, 20 years, both of them.

Yes, let's look at to our guidance. The CapEx is maintained more or less the previous guidance that we already said EUR4.4 billion, EUR4.6 billion on the CapEx. We still remain with the 5G deployment, quality. And remember that in IT, we have on a component on CapEx, and we also have OpEx related to the Cloud.

Perfect. Very clear. Thank you, Alberto. Thank you, Andrea.

Our next question comes from Vitor Tomita from Goldman Sachs. Please Mr. Tomita, your microphone is open.

Hello. Good morning all and thanks for taking our questions. Two questions from our side as well. The first one is regarding the 2026 revenue growth guidance, the longer-term guidance, does that already assume a relevant contribution from your B2B strategy or other fronts? Or are those more of a longer-term driver? And in those three years, the growth is likely to be primarily driven by mobile? And the second question from our side is on migration of users from prepaid to controller plans, which you mentioned just now. You've been doing that for a long time at this point. So how much more room do you see to increase the percentage of postpaid in your user base? And how high do you believe that percentage could get eventually. Thank you.

Okay. So, Vitor, on the first one, we don't share the exact breakdown of the different components of our revenue drivers. So let me give you a piece of information. So, the assumption on inflation on our plan at this point in time is around 4% this year for PCA and then going down to 3.5 in the years to go. So, the main assumption is that we'll be able to grow consistently above inflation in the short term and in 2025-2026 already. And so, this is driven by the overall portfolio of our revenue generation initiatives. So of course, we have mobile, which is our cash flow is an important one with this whole market rationality. And then we got exponential growth in B2B, for example. We got some kind of high single-digit of broadband, and we've got the customer platform. And so, when you look at, for example, B2B to go to your specific question, we shared with you in November that we have contracted revenues of EUR 300 million over the last 18 months. So, this year, we shared in the presentation that we're having 200 additional contracted revenues in 2023. But these contracted revenues extend on a period of, let's say, 5 years. And so, they will build up over time. And so, we are starting from almost zero, as we show in November, a couple of years ago, and we are quickly ramping up. So, if you move to the end of the forecasting period and you keep the speed of our growth and you pile it up over time, you have a sense of the composition of the B2B revenues that we are expecting at the end of our triannual plan. And so, this is basically something that can contribute point something to our growth revenue. So overall, it is going to be small compared to mobile. But in terms of all the initiatives, broadband, B2B and the customer platform are important for the speed of revenue growth. The migration is something that we have been doing for a while. But I would say that we will keep doing this for a while. So, there is always something new. So, for example, we've been working extensively on the OI customer base over the last 12 months. And that was a sort of new lake. If you look at the churn market, it's quite dynamic. So, you've got people that improve their, let's say, economic conditions, and therefore where we have the opportunity to move them up. So, if you consider the macro environment, the fact that the purchasing power of Brazilians over time is going to improve according to the scenario that we are looking at today and the dynamism of that specific segment, I think that we will continue to migrate prepaid to control customers at the speed that we are used to in the last 12 months.

Clear. Thank you very much.

Our next question comes from Marco Nardini from XP. Please, Mr. Nardini, your microphone is open.

Hello. Good morning, thank you for taking my questions. I actually have two here on my side. This quarter, you delivered a solid EBITDA margin alongside the highest ARPU and also reported strong guidance in top line and EBITDA growth going forward. Could you provide insights into the expected margin dynamics for the upcoming quarters of 2024, please? And my second question is regarding fixed broadband. I understand that you reported 9.5% growth in team [indiscernible] , but its contribution to consolidated revenues remain relatively low. What do you expect on fixed broadband growth in 2024? Can we expect some M&A here? Or do you believe that there is still room within this asset-light model? Thank you.

I’ll ask Andrea to address the first one, I will take the second one.

Hi, Marco. related to the EBITDA margin, we still want to continue to grow, but especially on the EBITDA after lease margin, there where we expect more results because the decommission and all the lease effects that we already mentioned. But we will continue with our focus in growing with more productivity.

And just to add it up, you know that the, let's say, cost control, productivity, discipline in capital allocation is something that is really in our DNA. So, we got revenues growing above inflation. So, some variable costs are related to that. We got a scenario of lower inflation, at least versus previous years and you got our commitment to increase operating free cash flow at the end of the day, and this then will be broken down at the EBITDA level and EBITDA of the lease level and the CapEx in terms of capital allocation. Going to your second question in terms of broadband, let me take a step back in terms of where we stand or what we see in terms of market dynamics, where we stand. So, when you look at broadband, you know that basically, we got a 2% revenue share in the specific market. And that is quite competitive at this point in time, one of the large player just lowered prices a couple of weeks ago on the entry level plans and so the market remains competitive. We don't see any impact on not being convergent at this point in time. And this is primarily because the market is highly fragmented. And so more than 50%, say, almost 75% of the market share is in the hands of a single business ISP. So, convergence is not a problem for our mobile business. And at the end of the day, we are sort of a pure mobile company because it's the majority of our revenues and profits and cash flow come from mobile, but we are underrepresented on broadband. Given the strength of our brand and the credibility of team, broadband, it's a nice adjacent market for us, where we could command a higher revenue…

Perfect. Thank you.

[Operator Instructions] Our next question comes from Carlos de Legarreta from Itau. Please Mr. Carlos, your microphone is open. Mr. Carlos, we lost your -- the beginning of your question. Please if you can repeat.

Sure. I was just reading the. Thank you. The first question is on the equipment side, I understand, obviously, it's a small part of the business. But I was just trying to understand, you do seem to have in the fourth quarter a nice increase in the volume of handsets sold, yet the revenue contribution is actually lower year-over-year. But on the full year, you actually have the opposite dynamics. We have lower number of headsets and an increase in the product revenue. So, I understand handsets are not the only equipment that you sell, but if you could talk about a little bit of how to reconcile this and what to expect going forward? And secondly, double-clicking on broadband or fixed broadband, is the penetration that you have of customers over total homes fast is relatively low. And I don't know if you conceptualize target penetration rate as a target for TIM. But if you could talk about if you have this metric in mind as a target number in the near future or in what time frame that would also be very helpful? Thank you.

Okay. So, I will go with the first one on a more commercial terms, and I will leave Andrea to comment on the numbers that you see. So, when it comes to our commercial approach on handsets, so basically, we implement our commercial policies with three potential benefits in mind. So, the first one is being attractive to competitors' customers. So basically, we want to put together a nice offer for a potential customer interested to switch. So, this is the first objective. And this is, for example, the Apple One initiative that we launched the third quarter last year. The second objective that we are looking at is we want to increase the life cycle of those customers in our customer base that decide to apply to that specific offer with the handset included. And the third one is the ARPU uplift. So generally, we tend to apply subsidies in the highest plans because we can generate the ARPU uplift. And we know that the quality of these either acquisitions or, let's say, not retention is cross-selling to our customer base, have the best quality. And so, in the quarter, we generally put together these three components depending on the moment. And specifically, in the last quarter, we've been a bit more aggressive on subsidies and the specific performance of that quarter because we are always assessing how it goes. And if we need to do some fine-tuning or adjustment to our commercial strategy. And if you look at the overall numbers of the years, I will leave this to Andrea.

Yes. In the last quarter, we had this seasonality because consider that we have the Black Friday and the Christmas period. So, we concentrate subsidy in this part of the year. When we look for the total year, we have more volume this year related to 2022. So, for the full year, we have an increase in revenue and cost. But for the fourth quarter, we have the seasonality of these two big commercial points.

Coming to the second question it was about penetration of broadband. So, when you look at our model, which is basically where an MVNO of broadband because we operate in an asset-light model. And one of the benefits is that generally, we are less interested with occupancy rates because these are not part of our contracts, and this is actually an advantage. So, we can operate on a larger footprint. It's like we launched a larger network, and we take the customers on a larger footprint without having the need of increasing penetration and tick-up rates on the specific district of that specific city and that generally put a lot of commercial pressure on filling up the network quickly in order to have payback. This is actually one of the main benefits of the asset-light model. And this is also the reason why we are rebalancing a bit our go-to-market approach in terms of commercial networks because we want to rely more on a pull component versus the push component. So not having the need or we don't need to be worried on filling up the network very quickly. We generally want to have a mobile like go-to-market approach, which is quite aligned to what we know how to do well. And at the end of the day, this ensures quality that ensure a better trade-off in between revenue growth and profitability.

That’s super clear. I really appreciate your comments and I will also [indiscernible]

Thank you.

Our next question comes from Phani Kanumuri from HSBC. Please, Phani, your microphone is open.

Thanks everyone for taking my question. So I have a couple of questions. The first one is related to your shareholder remuneration, which you said you will disclose on the seventh of March. So, I'm trying to understand if there are more decision points to be made? Or in a sense that do you already know the decision and you're just going to take some time before revealing the decision or you're still waiting for some other actions happening outside to finalize the shareholder remuneration?

We are finalizing Phani, the number in the discussion that we have with internally. And the message here is that in the previous guidance, we say the continuous improvement in shareholder remuneration so this is what we have been doing over the last many years. We moved from 1% to 2%, then 2.3% in November, since our plan was going faster in respect to what we had initially planned, we moved from 2.3% to 2.9%. And so, we are entering 2024 at a faster speed, and we are finalizing the number, and we just communicate the new floor this 7th of March.

Okay. The second question is largely related to your operating free cash flow after leases. The margin is at around 18% this year and your guidance suggests that it will go up significantly in the next two to three years. So, what do you think where we could be comfortable saying that your margin would be in two to three years' time?

Well, we expect that will grow in the coming years. So, like we put in the guidance in double-digit growing, but what we expect is the continuous of the growing in the coming years.

If I may, Andrea, I think we have released a pretty broad guidance as we usually do, and we have five to six KPIs that we expect at least to help you to model our business of course, unfortunately, we cannot give guidance on every single KPI. So, this one, we are missing, Phani. We'll let you guys calculate that. But considering what we expect on revenues considering what we expect on EBITDA and EBITDA after lease minus CapEx, it's not going to be that tough. And if you guys need any additional help on the qualitative elements, we can give that to you in the coming weeks. So, we can improve the way you calculate any of the other metrics.

Perfect. Thank you everyone.

Thank you, Phani.

Our next question comes from Gabriel Delima from Morgan Stanley. Please Mr. Delima. Your microphone is open.

Two questions on my end. First, anything you're seeing in the first quarter of 2021, that is worth highlighting in terms of the market? You already have the offer of the best drivers in time. I just wanted to get some color how you're performing. And the second question is a follow-up on the M&A question. When you say you're active, you mean that you are looking at everything in the market or your approach is to smaller companies and things like this? Just wanted to get a sense if, for instance, the OI assets that are on sale is an opportunity for TIM as well.

Okay. So let me go with the first question. So, when you look at the first quarter, the first quarter is generally a very seasonal quarter because you've got people coming back from holidays in January. We got annual carnival in Brazil in February. And so, everything is moving ahead according to our plans. So, no specific, let's say, element of discontinuity versus what we saw in the first quarter in previous years. What we have versus last year is that at this time last year, we didn't have any communication or commercial activities going on. So, if you look at what we did in 2022, in the first quarter, we were not having specific campaigns. In this quarter, on the opposite, we have what we call a summer campaign and which is the ZÃ Delivery campaign, and we announced the partnership in November. We are implementing now in January because it fits well with the recessively of recharge and getting a cold drink associated. So, we have more commercial activities on our side. We just launched ZÃ Delivery. Results to date are pretty good. And when it comes to the test drive, let me elaborate a bit on the on the commercial intent of that campaign. So, when you look at our positioning on the quality of service, basically, you can see that we closed over the last years, the gap that we have with our competitors in terms of actual quality delivered to our customers. And we have been consolidating since June last year, our position in leadership and that we look at this KPI, which is called excellent quality of service as the main indicator is measured by OpenSignal. Now nonetheless, there is a mismatch that exists between our actual performance and the perception of our customers.…

Cristal clear. Thank you.

Our next question comes from David Lopez from New Street Research. Please Mr. Lopez, your microphone is open.

Hi. Hello. Thank you for taking my questions and congratulations on a solid set of results. I just had one on the balance sheet, please. Your net leverage is quite low now. I was wondering what is the optimal leverage in the future? I know you cannot comment much on the shareholder remuneration today. But should we expect leverage to continue to grow close to zero? Or is it going to go up at some point? And what would be the optimal level, please?

Yes, our leverage is really very low. After the acquisition of OI, and we are in this very good results. And for now, we will still continue this impact, of course, that we will have some discussions about what happened if we have a change in the income taxes from the government. And when we have this information, we will start some position about our capital infrastructure. But for now, we are not thinking about changing our leverage situation.

David, there is another discussion that you guys are quite interested being in the previous month. In previous quarter, that was the interest on equity. And that could be a trigger to retain something since the discussion now has been postponed for potential implementation at the earliest in 2025. That's another element and this is part of our discussion when we look at that. And today, we've got a pretty nice instrument to address effective tax rate and support our increasing shareholder remuneration. And of course, there has been a lot of discussion here if this instrument was going to exist in the future being modified in the future. And so, this is just something that has been studied internally. But since, let's say, the discussion now has been postponed is something that is going to be probably discussed again throughout the 2024 when we see progress in the government news on this front, let's put this way.

Okay. Thank you very much. Very clear.

Our next question comes from Philip Chang from Santander. Please Mr. Chang, your microphone is open.

Hi. Good morning, everyone. Thank you for taking my question. Quick question on my side. I just wanted to understand if there is any update on the FISTEL payment discussions. And if you are still working with the base case of not having to pay FISTEL this year. So just wanted to see if there's any update there. Thank you.

I think we are still in the same position, nothing changed related to the FISTEL payment. So, we will maintain our previous position.

Perfect. If I may just do one quick follow-up. I just wanted to understand in the mobile segment, how the performance has been on the high-end consumers, right? Just wanted to understand if given that you have now the highest ARPU in the market, how do you see your relative performance among high-end customers, right, pure postpaid, if you have been able to gain a lot of traction there? Has this been an important driver here for ARPU expansion? And eventually, if we should continue to see this as an important driver for service revenue growth going forward?

Chang, this is a very good question because at the end of the day, when you look at postpaid, we got 22% market share and market leader is 44%. So, this is an area where we can grow. I mentioned in a previous answer that we are doing quite well. So, when you look at postpaid, we divide the plans in two families. One, we call it internally like pure postpaid, which is basically something above BRL 100 and the other one is hybrid plans that we call internally control. And we have been growing double digit on the pure postpaid and all the efforts that we are doing on our commercial strategy that is based on the famous 3B, best-service, best network and best offer is exactly to increase the perception among the high-value customers that we have these 3Bs with us and therefore, to attract them. So, it's a journey because to change perception, it takes time. We are putting all the elements together. And like in the test drive that I just mentioned in the previous question to Carlos, basically, we are working to improve our position in the high segment. And when you look at the hard number, it looks good because we're going double digit, but I think there is a long journey to go in front of us. When you look at additionally some of the things that we have been doing on our offer, the Apple partnership is exactly driven by our intention to increase the perception with high-value customers. You live in Brazil. So, if you fly domestic GOL and LATAM, our TIM black customers. So, TIM Black is the high-level plan family that we have here include free communication yet in the flights on us. If you look at the one of what was considered, let's say, a gap in our high postpaid plans offer, there was international roaming. We closed the gap last year, and now we've got the most attractive international roaming offer. So, we are doing a number of initiatives to sustain our quest to increase our position in the high-end customers.

Very clear. Thank you, Alberto, Andrea and Vicente. And congratulation on the strong fourth quarter results.

Thank you. Ladies and gentlemen, since there are no further questions, I'm returning the floor to Mr. Alberto Griselli for his final remarks. Please, Mr. Griselli, you may proceed.
