Good morning, ladies and gentlemen. Welcome to TIM S.A. 2025 First Quarter Results Video Conference Call. We'd like to inform you that this event is being recorded and all participants will be in listen-only mode during the company's presentation. There will be a replay for this call on the company's website. After TIM S.A. remarks are completed, there will be a Q&A section for participants. At that time, further instructions will be given.

Hello, I'm Vicente Ferreira, head of Investor Relations. Welcome to China Say's earnings conference for the first quarter of 2025. This video highlights our recent performance and how we see the market evolving in 2025. Afterward, we'll have a live Q&A with our CEO, Alberto Griselli, and our CFO, Andrea Viegas. Please note that management may make forward-looking statements and this presentation may contain them. Refer to the disclaimer on the screen and on our investor relations website. Now, let's review our results.

Hello, everyone. I'm Alberto Griselli, CEO of TIM. Despite a volatile external environment in the first quarter, we have seen a solid start to the year. We successfully implemented our strategy and delivered consistent numbers. Our mobile revenues increased by 6.2% year-over-year, driven by strong post-pay growth. Our EBITDA grew by 6.7% yearly, with margin expansion reflecting our efficient operational execution. We also saw a double-digit expansion in operational leakage flow, reaching R1 billion. In the quarter, we announced R690 million as interest on capital. Our strategic initiatives are paying off. Following the launch of a fully updated version of the Meu TIM app, we saw significant growth in users. We are boosting our presence in São Paulo with a 360-degree approach to customer experience, modernizing the network and revamping our go-to-market strategy in the region. The first quarter was also marked by notable development in the new business initiatives, with the launch of a new partnership and a special focus on the B2B utilities vertical. Service revenues started the year at a solid pace, growing 5.6% year-over-year. As mentioned before, the postpaid segment drove the revenues dynamics with close to 14% yearly growth. The 6.2% growth in mobile revenues results from robust postpaid-based growth, almost 7% year-on-year, and sound ARPU performance in postpaid and blended. The increase in mobile ARPU indicates effective customer monetization strategies, which emphasizes TIM's successful upselling efforts. Now, 50% of our base is comprised of postpaid lines, with revenues representing almost 70%. While we celebrate our postpaid performance, we continue to work on recovering the prepaid. Our three-step plan is designed for the medium-term, so resilience and consistency are key for the plan to bear fruits. São Paulo is the focus of a special project that aims to apply a 360 approach to translate our network leadership into customer experience and perception change. We are modernizing over 3,000 sites, which will significantly improve network capacity. In this network swap so far, we have seen a 40% increase in coverage and capacity, while energy consumption is falling 15%. This infrastructure evolution will further expand our network quality leadership, attested by Opensignal network consultancy, where we already had the best quality in the state and were awarded the best experience during Carnival. Now, we will have absolute leadership in all neighborhoods of São Paulo City. We are adjusting our go-to market in the region to help bridge this evidence to perception. We just launched a flagship store on Oscar Freire Street, an area famous for its sophistication and luxury spots. It is the Brazilian version of Rodeo Drive. This marks a significant milestone for us, showcasing to customers a different positioning where quality and value are prime. Adding to this boost in presence in São Paulo, we had the first edition of the TIM music event in the city. The results were fantastic. Tickets were distributed in minutes. We achieved massive engagement levels on social media, and it was a PR success. The concert was all over the media. The successful TIM music event and the new iconic store reflect a strong effort to boost brand perception and customer engagement. São Paulo is the country's richest state, so it's natural to be the focus of our attention, but we will apply similar tactics in other regions of the country. We are commencing a new stage of our 3B strategy. Changing gears to new revenue streams, our B2B IoT strategy is performing well. We've seen substantial growth in contracted revenues, particularly in agribusiness, logistics, and utilities. Specifically, in the last vertical, we are ramping up our presence. We are expanding the services we sell on our own and with partners, showcasing TIM's commitment to providing integrated solutions that enhance operational efficiency for clients in various sectors. In addition to our well-known solution for public smart lighting, we are now recognized in water management, gas distribution telemetry, and energy distribution metering. We are committed to further developing the B2B opportunity, expanding our addressable market, and opening new avenues of growth. Our digital ecosystem continues to expand, with significant growth in customer registrations and transaction volumes. Now we are launching new initiatives in the energy sector, partnering to create value in both B2B and B2C markets by exploring different energy distribution methods. We are set to initiate a pilot project in collaboration with Electrobras. In this project, TIM will act as a channel for Electrobras, selling its energy to corporate clients. With Toppen, we have just initiated a pilot project within the distributed generation model under a revenue share agreement. This initiative allows our B2C clients to participate in solar power plant cooperatives, enabling them to reduce their energy expenses. Our proactive approach to diversifying offerings and enhancing customer value through innovative solutions confirms our intention to take TIM’s value proposition to the next level. Now let's move on to the financial details with our CFO, Andrea.

Hello everyone, I'm Andrea Viegas, CFO of TIM. I'm pleased to share that we ended the first quarter with solid figures, reinforcing our progress in cash generation growth and shareholders' value creation. This quarter, I want to highlight our efficiency program, which will help us deal with the impact of inflation, both this year and in the coming years. The program we have been implementing since last year aims to improve productivity and customer experience while ensuring margin expansion. The focus on technology and organizational levers reflects a commitment to innovation and operational excellence. Our outlooks running below inflation reflect an effective cost management strategy, key to staying competitive and reinvesting in activities that can more directly impact clients' perceptions. This approach supports TIM's consistent EBITDA growth and margin expansion. Our EBITDA grew by 6.7% year-over-year, adding 80 basis points to our margin, which surpassed 48%. EBITDA after lease also presents a solid increase with margin improvement. Lease payments were stable compared to last quarter but grew high single-digit year-over-year. We have specific initiatives to control leases, so we'll focus on this in the coming quarters. Our net income grew more than 50% year-over-year, marking the 80th consecutive quarter of double-digit expansion and reaching the highest net income level for our first quarter in TIM’s history. To finalize our review of the financial results, it's worth highlighting our operational cash flow performance, another double-digit increase of almost 20%, with our cash flow margin reaching almost 16%. Despite seasonal effects, working capital improved significantly in the quarter. We also maintain a robust balance sheet with strong liquidity and manageable debt levels. Again, all these numbers reflect TIM’s capacity to turn revenues into cash and demonstrate our strong financial health. Now back to Alberto.

As we conclude, I want to summarize TIM’s strategic focus areas for the quarter ahead. First, our commitment to competitive rationality in the market is evident. We want to intelligently enhance our mobile value proposition. We are applying that to the prepaid recovery plan and expect progress in the coming months. Second, the emphasis on expanding the B2B IoT portfolio and growing our partnerships under the digital ecosystem reflects a proactive approach to innovation. Adding these new revenue opportunities will help us deliver sustainable growth. Third, the focus on operational efficiency translates into a more conservative view of TIM Ultrafibra evolution in a challenging broadband market. Fourth, this efficiency mindset permeates all areas of the company, and as Andrea mentioned, we have a program in place that covers OPEX, for this one we presented the levers we have today, working capital, in this case, we are finalizing a set of actions to help our performance throughout the year, and leases. As you know, since the days of the commissioning of Oi Towers, this is an area where we need to transform the sector. We need to change the relationship we have with the tower company. Before we conclude, I'd like to highlight that we have been listed on the CDPA list for the second year in a row. Today, we are the only operator in Brazil with this status. This is a clear demonstration of our commitment to sustainability. In conclusion, we have started 2025 with solid momentum, paving the way to meet our annual guidance. Our strong cash flow evolution and commitment to operational excellence position us well for the challenges ahead. Thank you for your attention. Now, let's move to the live Q&A session.

Before we start the Q&A session, I will hand the floor to Mr. Roberto. Please, Mr. Roberto, you may proceed.

Thank you. Good morning, everybody. Before we start our Q&A, just a quick remark. This morning, we were confirmed as the most sustainable company in Brazil. We ranked first among all companies in the Corporate Sustainability Index of the Brazilian Stock Exchange. This result reinforces our leading role in ESG among Brazilian publicly traded companies, and it's worth remembering that we have been in the selected group of companies for 17 consecutive years, the longest streak for a telco. Now, we can proceed with the Q&A. Please, operator.

Thank you. We will now begin the Q&A session for investors and analysts. Our first question comes from Bernardo Guttmann from XP. Mr. Bernardo, your microphone is open.

Hi, good morning, everyone. Thanks for taking my question. Actually, I have two here. The first one is related to mobile growth. The postpaid segment remains quite resilient, but the prepaid continues to perform below expectations. Could you elaborate on the adjustment made and the levers for improvement in the prepaid segment? And my second question concerns costs in the current inflationary environment. What are the main efficiency levers for improving margins throughout the year? Thank you.

Well, thank you, Bernardo. So, I will take the first one and pass the second one to Andrea for the cost one. So, on the revenue growth, we are seeing in this quarter a similar set of dynamics as the last quarter. Postpaid is the main driver of growth, primarily sustained by price adjustment and postpaid migration that was pretty strong in this first quarter, where prepaid is suffering. Just remember, Bernardo, prepaid is suffering in general. So, the market for recharges is decreasing as all operators are migrating prepaid customers to postpaid, and there is some constraint on the demand side. So, we put in place a plan on our side that is made up of a combination of the three levers that we discussed in the previous quarter, the offer itself that received a boost in this first quarter, the communication that we are trying to make a bit more consistent in time in order for the value proposition to come across to our customer, and some tactical actions on the channels. The objective of these plans is twofold. From one side, increase the loyalty of our customers to us. As you know, the churn rates in Brazil are still high, and the second one is to get a larger share of the market. We have in our plan negative growth for prepaid throughout the years, and what we are working on is to slow down the decrease over time. So, Andrea, maybe you can take the one on cost.

Yes. Hi, Bernardo. Related to the cost and margins, we are, as you know, always working very closely on the reduction of costs and our efficiency program. We have several initiatives, AI, digitalization, make-or-buy, and also a very cost-controlled approach in several initiatives inside the company. But considering inflation, our biggest concern this year is related to the lease because leases have a direct impact from inflation, and we are working on several initiatives related to leases to mitigate these impacts. Renegotiations with the towers, another program that we are putting in practice, and we are very focused on mitigating this specific line that is our biggest concern related to inflation.

Very clear, Andrea. Thank you very much, Alberto.

Bernardo.

Our next question comes from Marcelo Santos from JP Morgan. Please, Mr. Marcelo, your microphone is open.

Hi, good morning, Alberto, Andrea, Vicente, Luisa, thank you for taking my questions. I'll focus my questions on the growth of mobile service revenue. You already talked about prepaid, but I want to turn the attention a bit to postpaid. It was very strong, but I understand it was impacted by a different seasonality in the price increases. So, I wonder if you could help us a bit to understand how much bringing the price increase from April, May to March helped the growth of postpaid in this first quarter. And if you could give more details, like when during March was this increase applied, how much of the base was affected? I don't know, anything you could give there. What was the average increase? Just for us to understand how much of this increase could be propagated going forward. Thank you very much.

Okay, Marcelo. So, when you look at the revenue growth for postpaid, it's made up of three main drivers at the end of the day. So, we are talking about the price adjustment. At this point in time, we are talking about back book price adjustment. We are talking about prepaid to control migration, and we are talking about control to postpaid migration. So, when you look at the combination of these three factors, they all impact what we are looking at in terms of the results of this quarter. They came up pretty strong. And the three elements are in place. So, our postpaid customer base is growing healthily. This is the first note. We have pretty strong intra-postpaid migration. It's a double-digit growth. And then we got a different personality, yes, in terms of price adjustment that, as we mentioned in many one-to-one meetings, occurred in between the first quarter and the second quarter, with some anticipation of some cycles in the first quarter. So, overall, all these effects, they sum up to the strong performance in the year. When you look at the drivers going forward, we intend to have, for mobile service revenue, the postpaid as our main growth engine in the coming quarters. And as generally happens, you will see that growth tend to slow down in the subsequent quarters. And so, this will be a typical trend that we are likely to see in the coming years. So, when you look at the overall composition, we're going to have, or we are working on sustaining solid growth on postpaid, while we are working to have a slower decrease on prepaid going forward.

Perfect. Just a clarification, was the full postpaid base and control affected by the price increases?

We generally don't impact, and this is as in every year, we do the price adjustment on a subset of the postpaid customer base. We tend to keep some of the customers out, depending on the level of propensity and insurance or complaints. And we generally also have a few different moments in time when we do this adjustment. So, there is an adjustment that occurred in between the first and the second quarter, but there are further adjustments down the line of minor intensity.

Perfect. Thank you very much.

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

Hello. Good morning, all. Two questions from our side. The first one is a bit of a follow-up on Marcelo's question. I imagine that this price increase still had a smaller effect in March. So, thinking specifically about, had a small effect in the quarter, given that it was only implemented in March. So, we had some interesting ARPU improvement in this quarter. So, do you believe there is room for the ARPU in postpaid to improve further in the next quarter and maybe be a bit more of a boost to revenues? And the second question, on the same note, how are you thinking about full-year guidance for revenues at this point, given the good result in this quarter? Do you see room for upwards revisions or do you believe you are still thinking more about the guidance target as it is now, given that, as you mentioned, you expect some deceleration in that growth in the next few quarters? Thank you very much.

So, Vitor, let me take the second first because it's easier to respond. We are committed to delivering our guidance we just communicated a couple of months ago. So, that's our commitment. We're talking about roughly a 5% revenue increase over time. When it comes to ARPU, you need to remember that ARPU has been growing, our ARPU has been growing over time, both postpaid and blended. And you got a number of different drivers for this ARPU to grow. We need to see how this plays out in the coming quarters. Because you have something that is clearly accretive, like a back book price adjustment or front book price adjustment, whereby there is something that is more dilutive, like a prepaid to control migration. So, generally speaking, it is one key metric. We are number one in terms of ARPU. We still have to implement some front book price adjustment in the coming months. So, we got some forces pushing forward, but we also have some forces diluting the numbers, which is related to prepaid to control migration. So, that's for the first question.

Clear. Thank you very much.

Our next question comes from Gustavo Farias from UBS. Please, Mr. Farias, your microphone is open.

Hi, everyone. Good morning. Thank you for taking my questions. Two on my end as well. So, the first one, if you could comment a little bit more on leasing payments. I realized from the last conference call that most of the contracts are already tied to IPCA. And I would like to know if there is more room for negotiation, even considering this or any other levers that you are able to tackle to control leasing payments going forward. And the second one related to working capital, we've seen a pretty strong performance from working capital and contribution to cash generation. I would like to know what we can expect as a sustainable level of working capital and any other levers you are able to use to optimize it going forward. Thank you.

Hi, Gustavo. Related to the first one, the lease payment in this quarter was almost at the same level as the last quarter. But you are right; we have IPCA and AGPM that impact this contract. But most started at the end of March and April and May. So, in the second quarter, you will see the start of an impact of inflation on our lease. What we expect and what we already declared is that we are working to keep the increase of the total lease in the year lower than our revenue. This is what we are working very hard to achieve. Besides the negotiation that you mentioned and I mentioned before, we also have another lever that continues to our decommissioning, where we see which towers that we have are coming to the end of the contract and try to negotiate these two. Or renew the contract or move it to another lower-cost tower. As for the second question.

Let me just add something on the leases. So, Gustavo, on the leases, you have a set of levers. Which are these levers? So, as Andrea was saying, we got negotiation. Negotiation is something that is on the table once we need to deploy new towers. And there are some towers that are getting to the end of the period and we have the opportunity to renegotiate them to a value that is in line with market values. On the other hand, you have another set of levers that are the decommissioning of towers. They have been a focus of our company throughout the year. We decommissioned thousands of towers. So, we can do it. We can move towers. And then we got partnership with other operators, where we share the infrastructure, like the RAN share agreement with Vivo, for example. So, we have a large set of levers in our place that we are going to deploy in order to keep these line costs in check. It's something that is not like super short term. Something that takes years to accumulate, because there is some infrastructure required, but we are committed to using all the levers in place to meet the guidance that we shared at the beginning of the year.

Thank you. And related to our working capital, we are working very hard on this working capital, with several initiatives also that we have. But remember, we have seasonality. In the first half of the year, we have negative working capital. In the second half, we have positive working capital. We are still in this trend, but we improved a lot. As you can see, the first quarter of this year relates to the first quarter of last year. And we still have some initiatives to put in place, and we can discuss it as we did. Once we do this new opportunity, we will discuss it with you.

Very clear. Thank you very much.

Our next question comes from Felipe Cheng from Santander. Please, Mr. Cheng, your microphone is open.

Good morning, everyone, and thank you for taking my questions. My first question is maybe zooming in a little bit on the pricing dynamics, particularly here for front book. Our understanding is that your main competitors have already increased front book prices. So I was just wondering if TIM has any schedule here to eventually also implement price increases to the front book offers. And secondly, if I may also zoom in a little bit on TIM Live, I just wanted to understand a little bit the dynamics this quarter, right? What were the main drivers or reasons here to see a decline in revenue growth, right? And eventually, if you are studying any potential M&As, be it via selling your TIM Live operation or potentially buying other assets here to fortify this business. So that's it. Thank you.

So, Felipe, going to the first question, we are fully committed to market rationality. And so we are actually working on our front book price upgrades. So they will come in the coming months. So that's something that we are going to do. For the second question, the main drivers are basically the following. Before going to our performance, I would like to stress again that the market remains highly competitive. And therefore, this pressure, both the ARPU and we have quite a good ARPU, and churn level. When it comes to our performance, the second point of attention is that when we report our numbers, we need to remember that we have copper and fiber in the same numbers, differently from other market players. And copper is a technology that is fading out. So, we are losing customers there. And the result that you see on this quarter is basically the effect of a customer base that has been decreasing over the last nine months up until January this year. And there's some pressure on the ARPU that has been going down a bit. On the positive side, you have, in February and March, a customer base that is growing. I can confirm that in April, it's also growing. But we are not pushing hard on this, because as we mentioned on many occasions, TIM Ultra, our broadband service, is diluting our numbers. Therefore, we are somewhat sideline on this line of business while we are assessing all the options on the table on the inorganic front.

Very clear. Thank you.

Our next question comes from Phani Kanumuri from HSBC. Please, Mr. Phani, your microphone's open.

How do you see the competition evolving from new and regional operators like Resonet? Thank you.

So, Phani, clearly the smaller players are gaining some traction in the regions. I would say that so far the impact has been limited on us, and it didn't change our competitive dynamics in some response. It didn't trigger specific responses from us. We say that they are getting market share, but they're not changing the competitive environment as a whole. We are continuously monitoring if they are making an impact on our customer base. There is some, but it's not material to react at this point in time.

Thank you. Since there are no further questions, we would like to close the Q&A session and I will pass the word to Mr. Alberto Griselli for his final remarks. Please, Mr. Alberto, you may proceed.

Thank you. So, guys, we set off the year at a robust pace. Despite the external environment, we are successful in implementing our strategy and delivering consistent numbers. Although we expect a challenging year, we have a solid game plan in our hands that we intend to implement with confidence. So, I would like to thank you for participating in our video call today. Special thanks to our team for its commitment and focus, and I look forward to meeting some of you or all of you in the coming one-to-one sessions. Thank you and ciao.

This does conclude the fourth quarter of 2024 conference call of TIM S.A. For further information and details of the company, please access our website at tim.com.br/ir. You can disconnect from now on. Thank you once again and have a wonderful day.
