Good morning, everyone. Well, it's difficult to see everyone here from here. Yes. I thought that I was going to be able to see you all, but I know that you're all there. Well, it's a great pleasure to be with all of you at MorumbiShopping. Once again, good morning. It is with great satisfaction that I shared the solid results of Multiplan that reflect our performance -- operational performance that was robust and growth that is expressive in the sales of tenants that overcome the retail and retail, they go over the -- they go over the threshold and sales of the other stores in Brazil. We are investing on the long term in capitals in big developments through the multiuse complexes that integrate the shopping malls, the corporate towers, the residential towers. So we increased the synergy between the assets.
We have an experienced management of integrated systems that guarantee efficiency and predictability. We keep high margins and low delinquency and indebtedness that is aligned to the average rate and a competitive cost that ensures the solidity -- financial solidity for future investments. Looking up ahead, we see a lot of opportunities for growth, the increase of opportunities and profitability and also expansions that were launched in other things that we already showed. Besides the valuation, increase of value in the regions that we work. We also invest in innovation with the app multi-app, and we are reinforcing our commitment to providing differentiated experiences for our clients. It is in that way that Multiplan is structured to generate a sustainable growth and consolidate itself as a reference in the real estate sector and shopping mall sectors in Brazil.
So I wanted to summarize this presentation traditionally has a lot of people that are watching it for the first time. So the first slide, you can just see our properties. We have a portfolio with 22, 20 shopping malls, 18 of those were developed by ourselves since its inception in 2 towers, commercial towers with -- well, the 2 commercial towers. Besides the development of a real estate multi-use big 250,000 square meters of private area, which is a Golden Lake, that we're going to mention a lot throughout the presentation.
It's almost Brazil here, 200 million people that go to our malls every year. We have a DNA, as I told you, for developers. Our company has celebrated 50 years. So we have a track record of performance that is proven all throughout this half century of experience. We have a team that is very much focused and more so. We manage our malls every day, 24/7. We are managers hands on, and Marcelo is going to tell you a lot about this -- this result very quickly. I'll talk about the stability of results.
In one of these conferences some time ago, I found an investor of a long, long time ago. And I said, "Well, you're not going to come. And he said, no, I don't need to. You're like a Swiss watch. I see the results. I know that you're getting with my projections. I'm very happy. I don't need to bother you. I continue to be a happy investor." So that's great. And recently, I was reading an article that said, pay for stability. And I said, how much they pay for stability? How much is embedded in the valuation of our company, this predictability of results that they can present.
And many times, I see the analysts saying, "Well, this is a great result. Congratulations, how do you do it?" We do it with this with focus, having a structural people having a long-term vision, having the consumer as our main target, over 6,000 stores that we try to add value, once again, as Marcelo has said, with his experience with the multi-app and more so.
Well, let's go to the slide and focus on the right. We are going to compare the slides where the data of the shopping mall Association of Brazil, Abrasce. And what I want to call your attention to the slide we've shown in many times that it's very relevant is the participation in the shopping mall industry that has grown year-on-year. You can see shopping mall is opening here. Here and there, you grow the GLA, your grow the sales, your growth. Well, those of you that hear me for many years, I say retail grows inside of the shopping malls. We have the development of the cities. We have the development of the real estate. And we lack space on the street. Can you imagine that you decide to do a new investment and you open 200 stores. Where do you have a space?
So retail grows in the shopping mall. And we have a slice of the pie that is ever bigger of the sales of the shopping malls, our shopping malls are selling more. And when we see another data, which is how much we have of the GLA of the shopping mall sector, you can see that it decreases even a little bit, so this is what we're trying to have with our intense active management and the quality of our malls.
Well, on this slide, we try to show you in a post-pandemic period and also comparing with the data of the Brazil Association shopping centers, how much we've grown. The shoppings in Brazil, the street stores, restricted retail and shoppings multiple and 64% in Multiplan. And you can see that the Street retail grows only 19%. So it proves that our strategy, our intensive work has provided results. So we have here, for the first time, our festive data, the most frequent ones more famous that gives you better results. And we are comparing them. I'm not going to mention everyone, but Mother's Day, Valentine's or Father's Day, you can see how the performance of sales at the shopping malls, they compare again with the shopping industry in Brazil and retail in general.
Here, we continue -- still with festive dates, the Children's Day, Black Friday and Christmas. So a day traditionally, where retail online predominates on Black Friday, so online retail is the question that I hear the most in 2020. As Eduardo said, well, the retail is going to be online. Yes, for 6 months but what happen afterwards. You've just seen the strong recovery of sales. Once again, we compare the growth of the sales of the shopping malls of Multiplan that are growing with a CAGR of almost 18% once you compare it to the sales of the e-commerce [ 10.6% ]. So we can see that we are growing faster.
And how do we grow faster within the markets itself. So we have a penetration rate in the slide that we've just shown here, growing 291 basis points, almost 3% against the e-commerce within traditional retail, that just grows 82 basis points. So once again, our strategy to promote -- last year, we had 1,300 events in our shopping malls. This management of the mix that curatorship of mix generates results that are strong for the tenants and for our shareholders.
I'm not going to go over this slide. But for those of you that do not know a lot of the details, top is RibeirãoShopping in 1981, which was a farm of sugarcane and it became a big city. This shopping mall has over 10 expansions that were done right Marcelo? 10 expansions that were done to get to the size. And recently, we've done sales of terrains that are adjacent to the shopping model that will provide a new push, a new growth of the real estate itself. So we are planting the seats with the sales, the growth and the opportunities to continue to grow in the future.
This is just so you can see in another way. One of the ways that you can present results all throughout time. In an ever growing fashion, when you do a wise investment in the past, you choose where you're going to grow. What seemed that didn't have any growth. And in the future, in the middle of the farm, it became a big city, and we see the fruits of our labor, and this is just one example of many that we could give you right now. This is reflected in data. We can see it with the census in Brazil. We are taking a population in the city, the area that we are, where the shopping mall is or the income or the IDH or the development index -- human development index, and we can see how it's comparing to the rest of the country. We are growing faster. We've made the correct investment in the growth.
Talking about growth we were just discussing the real plan -- of the monetary real plan. And then we take that time and then we stabilize it and we can show you the crisis. Well, crisis is good because the other ones will leave and then you invest or the crisis good because there is a great opportunity for investment or worse, waiting for the crisis to go over, so you can grow, so you're going to be setting down because we try to always bring one of the most famous crisis. There were many others.
There was a lot of more information in the slide. We simplified in this line in the middle which is the GLA of the company that grows throughout time. That vision of the future allows us to do this. How many times we're in meeting with investors? How do you think it's going to be the GDP? I have no idea. And well, what about realist? What about retail? I don't know. But what I can talk to you right now is what are we doing to grow regardless of the scenario. This is what we're trying to seek every single time. We're focused on the consumer, generating value, seizing the opportunity and making our shopping malls better every day.
And then you can see on the next slide, what have we done all throughout time? These are the projects that were delivered all throughout this time and also the variation of the Ibovespa index. It goes up and down. That's a shareholding, that's the stock exchange in Sao Paulo Index,Ibovespa. So we are working with caution with the correct use of the capital allocation, trying to get the best returns to grow and generate value for our shareholders.
In the slide, we can show you since the listing of the company, we changed the date to 2007, July 2007, 18 years ago, we were listed in the stock exchange of Sao Paulo. And you can see the variation of our share, 371% valuation when Ibovespa is keeping 154%. That 371%, we can subdivide it between the valuation, which was 223% the valuation of the share and the other one is payment of dividends and interest over capital 148%. So the most impressive numbers are not here, are on the top. We raised BRL 2.7 billion with the primary offering and 3 secondary offerings that we've done. But we've returned to the shareholder [ BRL 7.1 billion ] through dividends or interest over capital and repurchasing of shares. And the 544,000 square meters that we developed all throughout this period.
Well, let's change and talk about results. This is a slide to show in a very summarized way, what we have done in 2024. I'm not going to go over numbers by numbers. But just to give you one number, 47,000 square meters of turnover. It's bigger than MorumbiShopping in 1 year. Besides the expansions, another 110 stores in the Diamond Mall and ParkShoppingBarigui. So just you can see the work that was done just last year to generate the results that we generate.
Here is a slide that the analysts are going to start taking notes, trying to show the sales in April and May. During the call, Eduardo mentioned that our estimations for April was growing 16.3%. In those few days that were the end of April, there was still 1 additional percent with 17.3% in sales. May growth of double digits in 14.6%. This makes this occupancy rate grow and the delinquency drop throughout time. This gives sustainability.
How do we do this? With everything that we identified before with hard work, improving the mix of making better malls every day of promoting events of the curatorship of the mix. This is an old graph for those of you that have been following us for many years, we can see that we're bringing this graph, well, this is the very well-known graph, which is the difference between the income of rent and then the cost of occupancy.
Well, a question that was asked over the last -- well, mainly last year of the cost of occupancy. Well, the cost of occupancy of Multiplan is it sustainable? Do you think that you're going to keep growing many times. When you see this on the short term, Well, look at the long term, actually. You can see how we're going. So we took once again, since the listing in 2007 base 100 to show the sales and the revenue of allocation. While we do -- we are going to multiply by the inflation, the GLA, you can see that our rent grew more, the valuation of the points within our malls, our enterprises brought value in it made that growth of revenue over allocation, overcoming sales and overcoming the own GLA. The cost of occupancy, it dropped from 14.9% to 12.8%.
And it grew -- it's an opportunity to grow more, to charge more. And how did it drop? It dropped because the sales came up? No, not just that. It dropped because of efficiency -- equipments were changed. So we can be more efficient using energy, the model of management, all the areas in the shopping malls, they adapted for the use of technology. And this is what Eduardo said. This is what we're seeking at all times every day, 24/7. So let's talk about towards the end of the presentation.
Very quickly, debt the presentation. Well tomorrow, we have Super Wednesday. Let's see what will come from coupon or the Fed. But anyway, so the average cost of the debt is 14.81%. Today, the Selic rate 14.75%. The net debt 2.28x aligned with our record that was 3 times was 1 time in the recent past. And with the schedule of amortization of debt that is absolutely handwritten. So it's hand written in the sense that we don't want to have any risk of refinancing, we do not like to have a big debt that is due that would compromise our freedom to [ Brazil ] freedom to take opportunities and to use the best capital allocation that we can do is our differential.
Once again, results of 12 months not the result of last year, even though there is an influence. You can see these gold metals are records. Records of a company that is 50 years that was listed 18 years ago is not simple to beat your own best record. So we have to beat our records and present expressive numbers and margins that are very high. In operational margin or NOI of 92.7%, where margin of net income, 51.4%. This is really good. So well, I wanted to mention an idea -- well, something that happened to me. Well, we were on a plane, and I was talking to an investor. And then -- he told me, look, a business with an EBITDA margin of 70% is for very few. And I said, thank you, ours is higher. How much is yours? Well, the last 1 was 74% -- 75%. It's very nice to see these numbers.
So this is a number that I like the most because it's not a quarter, it's not the last 12 months. It's the record. This is since 2007. Here is a size track record that is enormous that we are delivering and showing to you and that we're growing year-on-year. We've had a period on the pandemic that made that trough that whole. Otherwise, this graph would have been more harmonic more balanced and upwards, reflecting the great work of the company, reflecting that the capital allocation of the company and what it does, it generates value in our shareholders.
Talking about capital allocation. Last year, we had the record capital allocation, BRL 3.6 billion allocated in a single year. This first quarter, we saw a small reduction and we hope to have a reduction in the capital allocation, of course, comparing to last year, but we are preparing the company for a new cycle, new opportunities of investment up ahead where the CapEx of revamp. Well, this is a very frequent question over the last 15, 18 months. Well, you're investing a lot in improvement of the shopping malls, and we're going to talk about this people will comment with you and we'll show you in practice the effects of these revamps showing that in the first quarter, we reduced a lot what was last year.
And last but not least, the last slide is to show you. Do you remember the first slide that I just showed you, our portfolio? Well, the opportunity is unique that we just had in capital allocation. For those of you that I think that things are luck, there is no luck. There is a bit of luck, but there is preparation. We prepared ourselves. We were deleveraging the company. We were preparing for an opportunity of investment that could be an x opportunities, M&A market is very strong. You saw opportunities of developing. We could have done an x amount of capital allocations, but we managed, well, there is a saying that says time is essential. The time worked out. And we did the allocation that brought us a bigger return -- brought to our shareholders a better return. So we can purchase a part of every shopping mall at a cap rate that is 11.9%.
And in May, when we close the presentation, it was 10.6% and still with a potential that is tremendous once you compare it to the average record of the discount rate since the listing of the company of 7.8%. Another way of seeing this is to do the math. And okay, this way is great. You have BRL 2 billion of working, but the interest went up. Well, where you were was 10.5%, it went to 14.75%, we did the math and share until May, valued 21% gains, a great valuation and generated for our shareholders after the carryover, a return of BRL 361.4 million showing the opportunity that we had this big investment is big repurchasing in terms of return. Consequently, you see in the cash flow CAGR per share, a very important positive impact through the canceling of the shares, generating a strong -- generating value for our shareholders, which is the objective of the repurchasing.
To finish, regardless of the growth of 21% that we've just seen in the price of the share over this year, I am still shocked when I see this type of slide. And we do this every day. We see every day, we follow every day to understand. Understand where we're going, what is happening. So what have we done? Here is another story that people are tired of hearing me out, but this sector is called is a good proxy. It's an equivalent of a real -- well, I don't feel like a proxy at all. We are not a bond we are not compared to a debt instrument or maybe even convertible with an equity of kicker something that generates more value because the fixed income is to rescue, but we continue to grow and generate value.
So when we see throughout the recent history, 10 years, the NTN-B longest one and we compare it with the yield of the operational cash flow, and we've seen that we got periods that we were less profitable by the NTN-B and this is explained by the growth that we are delivering that we are announcing that we are building that we are doing. And even so, it's still negotiating the share with the biggest spread -- the biggest spread that we've already negotiated.
So I stop here. I'm going to call my colleague, Marcello Martins, to continue the presentation for you. And thank you very much.
