I'd now like to turn the call over to Mrs. Cristiane Barreto, our CFO at Oi. Please, Mrs. Cristiane. Good morning, everyone, and thank you for joining our fourth quarter conference call. I'd like to introduce our new CEO, Mateus Bandeira. This is the first time he's interacting with the market. Mateus took office as the CEO on the 1st of February and has been participating actively on our operational agenda, having meetings with creditors and regulatory discussions with Anatel and with the Federal Accounting Court. Mateus has a wealth of experience in managing transformation and restructuring companies. Thales Paixão, our legal officer, is also going to be joining the call. Would like to thank Mr. Rodrigo Abreu for all the contributions he's made in the past four years. He led the development of Oi Fiber and the sales of the UPIs mobile and InfraCo. Rodrigo will continue to assist us in his position as a member of the board of directors. Now I'd like to turn the floor over to Mateus Bandeira, our CEO. Thank you, Chris. Thank you, everyone, for joining the call. Before we speak about the results themselves, I'd like to talk about the three main pillars we have in the company and our progress in them. We start on slide three. The first pillar is extremely important and directly connected to the strengthening and growth of a fiber business, coupled with the process of continuous improvements in operations. The second pillar has to do with the restructuring of the debt, and it's key for the core to provide reorganization. The last pillar has to do with the legacy, its costs, and without that, the company would not be sustainable. We're now on slide four, and we'll talk about the first pillar. We'll show some highlights of our results. In the fourth quarter, revenues were significantly impacted by the macroeconomic environment that was unfavorable, and they were therefore lower and slower in the fiber industry as a whole. The macroeconomic scenario is challenging, but we continue to work tirelessly to improve the company's operating efficiency, and that can be seen in the positive results that we have, such as reductions in operating costs and investments. Our revenue was BRL 2.3 billion in the fourth quarter. That's 13.1% reduction year-over-year. That's mainly due to the impact of non-core revenues, that is, copper and DTH. Nonetheless, the core revenue amounted to BRL 1.6 billion, approximately 70% of our total revenue. Our fiber revenue, the main leverage for growth for us, amounted to BRL 1.1 billion in the fourth quarter pro forma. That is a 1.9% growth year-over-year. That was boosted mainly by the increase of 111,000 connections in the year of 2023, and the total number of homes connected in our fiber network is 4 million. Oi Soluções had a 9.3% reduction year-over-year, and that is mainly due to the drop in our B2B telecommunication services. When we look at our operating costs and CapEx combined, we see an 8% reduction year-over-year. This is evidence to our continuous efforts to improve companies' efficiency. Slide 5. Let's talk about the restructuring of the company. I'll give you an overview of our performance. In October 2022, the company hired Moelis & Company to support us in negotiating with creditors and to help us optimize the debt profile. In 2023, we had many discussions and different negotiations to make sure that we have, for example, the liquidity necessary to pay the DIP financing installments. On the 23rd of March, we concluded the negotiation phase with the Secex's Consensus Commission with very favorable terms that I'm going to talk about later on in the call, and that allowed us to continue to make progress in the RJ, RJ being the court-supervised reorganization. On the 25th of March, we had the general creditors meeting. It was going to take place on the 5th of March, and then it was suspended, and it started on the 25th and ended on the 26th of March. The company showed consensus with most creditors being at class three level and with suppliers being take-or-pay about the main commercial conditions in the RJ plan. We see this agreement with creditors as a very important milestone for the plan to be approved in the general creditors meeting on the 10th of April, hoping to have a bridge loan in April and the rest of the new money in the first half of the year. I'd now like to turn the call over to Thales Paixão. He'll be talking about our court-supervised reorganization plan, our RJ plan. We're now on slide six. I'd like to talk a little bit about the structure of the plan that we have proposed. We understand that this plan is close to an agreement when it comes to its negotiation. We'll be capturing new resources with creditors and third parties to execute our business plan and pay the credits in the new plan. We have unsecured credits elected by the new financing with a senior position in the guarantee package, with a payment being brought forward with the sales of assets. We have a participatory loan. We have special payment conditions for partners and suppliers, and also the option to restructure credits for partner suppliers that are take-or-pay. On slide 7, we see an overview of the general results of the RJ plan based on the structure that we agreed on with creditors. When we look at the financial debt reduction that was submitted to the RJ, we see that there can be a level of 70% reduction. That, of course, will depend on the decisions by the creditors and their choice of payment methods that we hope are going to be quite significant. We hope that we get to the 70% mark. Thinking about the debt profile with the main credits that are going to be amortized as of 2027 in the period in which the UPIs are going to be completed in their sales. The restructuring of the take-or-pay credit, mainly thinking of the towers and the satellites, is going to have an 80% reduction in the cash payments to creditors that amounted to BRL 12 billion, and the terms agreed, and also thinking of the original conditions that we have. Of course, the shareholders will benefit from participating in a more sustainable company with an improved capital structure. Now, I'll turn it over to our colleague to talk about the regulatory front on slide 8. Following the discussions that began in October with the Federal Accounting Court, Anatel, the Ministry of Communications, and Oi, we made significant progress this week. The TCU's Consensus Commission completed the phase of creating a solution for the existing issues between Anatel and Oi arising from the concession contracts and the arbitration. A governance procedure will be respected to validate the terms of the agreement by the parties prior to the assessment by the Prosecutor's Office and the Federal Accounting Court board. The company expects the Federal Accounting Court to issue a decision in the first half of the year. It should happen in about 30-60 days tops. Oi seeks to address the following points: immediate migration from concession to authorization, which is critical for the company to start demobilizing the legacy structure so that we can provide a new tax solution to our customers. The second point is the removal of the burden of asset reversibility, allowing the sale of these assets, and that is also critical, and this has always been controversial, but it is going to allow us to sell the assets at fair prices and faster. The third point is addressing obligations related to Anatel fines transaction until the end of the arbitration. And four, opportunity for Oi to continue defending its interest in arbitration with the expectation of receiving positive net amounts if we consider the investment commitments that we have made. We hope that the arbitration will be resumed after the agreement is signed and that a partial decision on the merits of the case will be known in the short term. On the operating front, because of the agreement, Oi seeks to immediately adapt its concession to an authorization model, as I mentioned, providing flexibility to better manage the profitability of the legacy services and the costs associated with them. We have a strong cost reduction plan that aims to capture strong efficiencies with a focus on copper decommissioning and customer migration actions to drive sustainability in the long run. I'll turn it over to Rogério Takayanagi, Head of Strategy and Transformation, to talk about Oi's operating evolution and revenue. On slide 10 now, we can see that the core operations already account for 72% of our total revenue, highlighting the importance of fiber and digital services in driving our growth and sustainability. Consolidated net revenue fell by 13% year-over-year. This fall can be attributed to the persistent impact of non-core services, especially copper-based services and legacy technologies, for example, satellites and microwaves. Now, on the right-hand side, you can see that the core revenue decreased by 2% in 4Q23, and that is mainly related to a decrease in B2B revenues from Oi Soluções. And you're going to see later that this revenue is centered on core services, which unfortunately surpassed the growth in the fiber and digital services. Now, on the next slide, 11, we can see more details about our fiber performance. The highlight here is the growth of Oi Fiber, whose revenue increased by 2%, mainly driven by the expansion of our customer base through the sales of high-speed broadband services. In the full year of 2023, fiber revenue showed a strong performance, achieving double-digit growth of up to or actually exceeding 10%. Now, on the right-hand side of the slide, you can see V.tal's expansion, and we are the controlling shareholder of the company. We announced agreements with Sky and Vero Americanet in the period, further improving the company's robust customer portfolio. Our rationale here is focused on providing special services, superior services to our customer. Oi stands out as one of the main fiber companies in the country, leading the market in 296 cities. In a recent survey, Oi provided the fastest broadband service in 10 states, resulting in high levels of customer satisfaction. There was another survey that showed how superior our customer satisfaction is. We want to leverage our renewed commercial strategy centered on quality-focused initiatives to resume growth in net additions. To reach that goal, Oi will prioritize growth in areas with existing coverage, employing a multi-channel strategy that encompasses local and digital channels, but especially digital channels. Also, we are adapting our approach to different regions, adjusting prices, channels, and marketing strategies to cater to specific local requirements and preferences. Looking forward, we are confident that our quality-focused differentiation strategy should generate future growth opportunities. We should note that the commercial activity has already shown improvements driven by Big Brother campaigns, which improved brand perception and led to better performance in gross additions. These factors, combined with greater efficiency in sales, should result in positive net additions in March 2024. On slide 12, there was a decrease in traditional revenues, especially driven by core technologies in line with what we see in retail. Good news is that we have been replacing that technology with fiber and in combination with new digital services. We should highlight that ICT revenue performance grew by 16% year-on-year, playing a crucial role in the offset, in the drop of the traditional services, which contributed to the 9.3% reduction in Oi Soluções revenue. ICT revenues accounted for 32% of Oi Soluções revenue in 2023, a 7 percentage point year-on-year increase. As you can see on the right-hand side, some verticals saw strong growth. Cloud revenue increased by a whopping 87%, while cybersecurity revenue saw a solid growth of 23% year-on-year. We have also seen a very significant acceleration in contracts for AI and cloud. Now, I'll turn the conference over to Cristiane Barreto, CFO, to present our cost structure and financial performance. On slide 13, we can see the result of our efforts to restructure the company's cost profile. Routine operating expenses fell quarter-on-quarter due to savings in personnel and content acquisition, as well as leasing and administrative costs, while one-off effects affected the year-on-year comparison. As you can see on the left-hand side, routine operating expenses came to BRL 2.3 billion, a 12.4% quarter-on-quarter drop, and a 5.2% year-on-year increase. If we exclude the non-recurring effect on the reversal of tax provisions in 4Q22, costs would have fallen by 10.6% in the period. The personnel expenses fell by 7.6% to BRL 432 million. This reduction is due to our ongoing efforts in optimizing the structure, which led to a reduction of 5,000 employees, or 23% year-on-year. Third-party services remained stable year-on-year, as significant savings in the acquisition of content and G&A, which fell 27% and 15% respectively, were offset by lower electricity tax credits. Lease and insurance expenses fell by 12.6% year-on-year, mainly due to one-off efficiencies and also lower lease in the quarter. Over 50% of the 4Q costs, excluding personnel, are related to the legacy business, which places more emphasis on the importance of reducing those operations. On slide 14, routine EBITDA was impacted by losses from the legacy business and lower growth in core revenues. I'd like to highlight that these results reflect the transition phase in which the company finds itself, as margins will begin to improve as the company becomes more cost-efficient and the fiber customer base grows and the economies of scale begin to bear fruit. We will have great opportunities to improve margins through the implementation of strong legacy cost reduction initiatives. Now, on the right-hand side of the slide, you can see that our CapEx came to BRL 186 million, roughly 8% of sales, a quarter-on-quarter reduction of 12.2 percentage points. This is a new CapEx level for the company, in line with Oi's transition to a business model with low CapEx needs. It reflects a disciplined and strategic CapEx allocation aimed at promoting sustainable growth with opportunities for future efficiency. The biggest CapEx impact is related to the costs that we need to incur to improve the fiber business. On slide 15, you can see our cash position in the quarter, which benefited from the mobile UPI price adjustment agreement and also the operational consumption that was expected in the period. We also had one-off disbursements and payments to suppliers in the quarter, which generated a working capital consumption of BRL 385 million. The disposal of the towers contributed to higher lease payments, which came to BRL 271 million. Our total cash position was BRL 2.2 billion at the end of the year, a drop of 12% when compared to the cash position as of September 2023. I'll turn it back to our CEO, Mateus, for his closing remarks. Thank you. We have made substantial progress for sustainability in legacy and restructuring. As Mateus mentioned initially, the second half of the year, not only the fourth quarter of 2023, was a time when we had readjustments in fiber and we also had new launches in our offer portfolio. In March 2024, and as of this date, we're going to resume our growth in fiber with a national footprint, and we're going to continue to make adjustments to the operating processes. We also expect to have more efficiency in the legacy management. In March 2024, we had the main points in the Secex Consensus Commission, and following all of the expected governance postures, we're going to present it and have the courts, the Accounting Court and Anatel courts, have the confirmation of it, and we're going to migrate to the authorization model. In the restructuring process, in March 2024, we had final adjustments in the commercial package of the plan, and now everything that was discussed and negotiated is going to be seen in the documentation for the RJ plan. On the 10th of April, we're going to have the general creditors meeting when the plan is going to be voted on, and then we're going to have more liquidity, new money. We're going to have the approval of the plan in the second half of 2024, and then the challenge to execute all of the measures in the plan. I think these are the main points that we wanted to highlight that are going to have effects beyond the results of the fourth quarter of 2023. Now, start the Q&A session. To ask questions, please use the Q&A icon at the bottom of the screen and write your name and your company. After your name is called out, a pop-up will allow you to unmute your microphone. If you prefer, you can also send your questions in writing. Let's start with our first question now. Leonardo Olmos, from UBS. Leonardo, [Foreign Language] iremos abrir o seu áudio para que você possa realizar a sua pergunta. Leonardo, you may unmute your microphone and ask your question. [Foreign Language] Oi, bom dia a todos. Good morning, everyone. [Foreign Language] Tenho duas perguntas. I've got two questions. [Foreign Language] Vocês poderiam discutir a desconexão que a gente viu em fibra? Could you talk a little bit about the disconnection in fiber? There were 8,000 people churning. And there are some large areas that continue with net addition. Even levels that have good net adds, some areas in São Paulo improved. So why do we see these net disconnections in the fourth quarter? And in 2024, do you already see any improvement in the first quarter? Do you have positive expectations? And the second question has to do with the ClientCo. That could be negative due to the contract costs with V.tal. Is the ClientCo margin negative? And I think the main question is, thinking about the future, can we expect to have a positive margin for ClientCo? In the past, you used to talk about a 15% EBITDA margin for ClientCo. What would be a normalized margin for them? And I know there's the sale and there's the concession. I'm thinking about the operation as is and normalized. Thank you. Thank you, Leonardo, for the question. As for the disconnection, we see net growth. Your description is correct. From a margin and quality perception, we see that it has helped gain momentum in sales. The disconnections are because of churn. We still have a high churn rate now that we have focused more on quality. So the churn that we see is inventory churn because of the lack of payment. And that's impacted by the macroeconomic scenario, of course. What we see in the first quarter is that this curve is changing. There is a continuation of net adds and a decrease in churn because of the improvement in commercial processes. As for the fiber product margin, as you know, this is a scale business, right? And we're transforming the model that was a CapEx-intensive model, and now it's an OpEx-based model. As the scale increases, not only for Oi, thinking about the client base, but also with V.tal, with new clients, then there is a dilution of fixed costs, and that should lead to an increase in our margin in the medium to the long term. We are still investing in this transformation process. Thinking about fiber, we already had this 15% margin. We had it about a year ago. We continue to seek improvement in efficiency. We have lower margins in the very short term. All right. Thank you very much. Thank you, Leonardo. Thank you for your question. To ask questions, please click on the Q&A icon at the bottom of the screen and write your name and your company. Once your name is called out, you will be able to unmute your microphone. Then you can ask your question. Should you prefer to send your question in writing, that's also possible. Agora, gostaria de passar a palavra para o senhor Luis Plaster, diretor de relações com investidores. Good morning, everyone. I am going to be reading out the questions from the platform. If you would like to ask any questions, please send them through the Q&A icon. The first question is from Alessandro Cavalcanti, an individual investor. His question is, when should the arbitration come to an end? Now, this is going to be resumed. And the share of Oi and V.tal and ClientCo, once that has been sold, what is going to be remaining for Oi? We expect a partial decision in four months at the latest, and a final decision between 12-24 months. Now, as for the second question, what is going to remain for Oi once ClientCo and V.tal's shares are going to be sold? It's mainly going to be B2B, Oi Soluções, and our participation, our share in V.tal. Thank you, Mateus. [Foreign Language] A gente tem uma segunda pergunta aqui que ela é em inglês, então eu só vou dar segundinho aqui para a gente ver como. We have a second question here in English. Let's just see how we're going to go about that. [Foreign Language] Então, como a gente está sendo democrático aqui, estamos respondendo as perguntas em português. Being democratic here and answering questions in Portuguese and English. This next question is going to be asked in English. [Foreign Language] A gente vai responder ela em português, mas tem aqui a. We're going to answer the question in Portuguese, but we have interpreters translating into English. So Stefano Podeschi 's question, and it's also an analyst from Morgan, is, can you please confirm that all financial creditors will be offered an opportunity to lend new money, and will creditors be able to participate pro rata to their holding of the financial liabilities? Thales is going to be answering this question. The answer is yes. All financial creditors will have the opportunity to lend new money, and they will also have the chance to participate in the creditors pool that will participate in the payments. The final plan is still subject to discussions when it comes to their terms and conditions with the main group of creditors, and we are going to disclose the new version of the reorganization plan as soon as possible. This is going to go to a vote in our creditors meeting in April. We have another question here from Uriel Silva dos Anjos, individual investor, and he's asking, what is the reason behind the reverse split of the stock with 10-to-1 instead of 5-to-1, which could be a solution? So, Cristiane, if you could address that question, we would appreciate it. Thank you very much. Well, we analyzed a few scenarios, and if you remember, we did that last year due to our stock volatility, and we think that the 10-to-1 model would be interesting in the short and medium term, considering the future events that we have in our reorganization plan. Thank you, Cristiane. Once again, if you would like to ask questions, please feel free to submit your question using the Q&A tool. We're going to stand by for a few seconds, for a few moments. If you have any questions, please feel free to submit them in the Q&A feature on your screen. If you'd like to ask a question, please click the Q&A icon at the bottom of your screen and type in your question. [Foreign Language] Uma pergunta que tem aqui que a gente recebeu também de investidor. We have another question from an investor. [Foreign Language] Ele comenta sobre o fato da gente ter falado sobre melhorias. He said that we talked about increased net adds starting in March, and he's asking if that improvement is related to improvement in macroeconomic scenarios. Also, he's asking about the churn trends, if they're going to improve because of that. Well, Plaster, thank you very much for your question. We believe there's still a big challenge in terms of the macroeconomic scenario and the competition, which is under pressure. So consumers oftentimes move from one carrier to the other because they find themselves unable to afford one of them. So what we have been doing here is to change our processes when it comes to acquisition. For example, as we said in the presentation, we have been able to strike a good balance between quality and increasing volume. And all management processes related to payment and collection have been helping us, of course. Of course, this is a slower process. We can see the impacts coming so quickly, but we are going to start seeing improvements in the first half of this year or the first quarter. Okay. I'm going to wait for a few moments to see if we get more questions from our audience. If not, we can conclude our call for today. We don't have any more questions, so. [Foreign Language] chegou uma pergunta aqui. Okay. We have another question about Anatel, but I think that we have already addressed it. It's about Anatel's arbitration procedure. With that, I believe that we can end our earnings call for today. So I'd like to turn the conference back to Mateus Bandeira for his closing remarks. Thank you so much for joining our earnings call. I'd like to thank the investors for their trust in our company, and our investor relations team is at your full disposal in case you have any further questions. See you in our next call. Thank you very much. Thank you. This concludes Oi S.A.'s 4Q2023 earnings call. If you have more questions, please access the company's IR website. You may disconnect now. Have a good day.
