Thank you. Good morning, everyone. Thank you for joining us in today's conference call to discuss about the results delivered in Q2 2022 by Cogna. With me in this call, Frederico Villa, our financial VP, Mario Ghio, our Vasta CEO, Bruno Giardino, Vasta CFO, and Eduardo Honzák, our IRO and Corporate CFO. I'd like to start today's call on slide three, where you can see our strategic reading of the results delivered this quarter. At Kroton and Vasta vertical units. We will look at Cogna's consolidated numbers. At Kroton, this was another quarter improving our main financial and operating metrics. Q2, now for five consecutive quarters, Kroton has improved, reducing revenue year-over-year, but with a growing recurring EBITDA. It translates into a higher margin.
We've had an important growth in our base, graduation growing 12.5% and post-grad growing 23%, showing the power of our capacity, you know, to attract new students and also to retain our current students. Kroton, and I always like to highlight that, shows metrics that we hardly find all together, you know. Now we see these results, these simultaneous results at Kroton. A growing student base, a higher intake in the last trade cycle but also a reduction in the cost of customer acquisition, the CAC, so we are more efficient. We've reduced our delinquency rate, showing that new students as well as renewal students have a higher quality. As a consequence, we also see a lower student dropout. This combination has helped us attain these results.
It's something very hard to have all of these great results in so many different metrics. Also, in the last two quarters, we had a growth of EBITDA margin despite all the effects on the economy. That's really important, and it shows the strength of the work we did between 2020 and 2021, our constant search for efficiency. Also, looking at Kroton strategic pillars, Kroton Med has met all of our expectations this quarter. Our revenue is growing strongly this quarter compared to last year, so showing that our capacity to grow organically is really robust. From the viewpoint of customer experience, we are focused on improving customer experience. Our strategy is for us to have a contactless and a frictionless journey.
Of course, our on-campus content is still our priority, and it shows that we have the best grade, comparing companies of education that have public education companies. Now talking about Vasta. Our net revenue growth has come to 34.5% in the quarter. It means that we're moving towards achieving the ACV target of BRL 1 billion. We will provide further details, but this is strongly supported by the growth of partner schools in our customer base, growth of more than 50%. Of course, an increased penetration of complementary content in the customer base. In addition, I'd like to highlight the top quality of this revenue, more concentrated in subscription products, which is our strategy as we have announced. It means that we have been able to do this with very high quality. Vasta is also advancing towards being a complete and end-to-end K-12 platform.
We have this new investment in Eduk Bank to provide more services to our partner schools, in addition to the services we already have available on the platform for partner schools. As regards ESG, we have launched our first sustainability report of Vasta, showing our commitment to disclose the company's results. This has been excellent work. Congratulations to our team. Talking about Cogna. I believe that, my first highlight, and I will announce that in great joy, this is the fifth consecutive quarter that we show operating improvements in this competitive scenario and still facing the challenges post-COVID. We have been able to maintain consistent improvements. Our EBITDA margin growth, driven by Kroton and Vasta, and we also had improvements in recurring OCG with cash conversion of over 38%.
We know, of course, EBITDA and EBITDA margin is very important, but OCG really shows the quality of the management work. With this operating cash generation, we've been able to keep a stable leverage. We are having consistent drops in leverage. We are very distant from the covenant of three times. Looking ahead, we see positive operating cash generation, and so our leverage will continue to be reduced. On the ESG front, we are making progress on a number of fronts. We've launched our greenhouse gas inventory. We were the first education company to do that. At Vasta, they have this program, SOMOS Afro. This is an inclusion program to include the black and mixed race population, which is extremely interesting.
Only to give you a few numbers, this quarter we conducted more than 220 social projects, including 50,000 people who received these services, especially healthcare and education. We need talents, and we are very happy because we have just received the Great Place to Work award. It shows the work we have done on culture building, and we will continue to do that. We've launched Hub, which is Cogna Innovation Hub. We call it a factory of startups. That is, we now have a team dedicated to supporting thesis that are developed in the company with founders that may create products that today we do not have in our portfolio, but they may potentialize our growth in the future. With that, I'd like to move on to slide five to talk about Kroton results.
Our student base has grown more than 12% in total, led by low on-campus content programs, which is the previous, premium and 100% online, so a growth of almost 14%. It doesn't mean that we're not growing in higher on-campus content programs, you know, with laboratories that's also growing about 9%. The high on-site attendance or high on-campus content. This is precisely our strategy. That is the focus of our company. This growth was supported by different initiatives, commercial, marketing initiatives, but also the expansion of more than 1,000 hubs last year, which has supported this growth in the first two quarters of 2022, and it will continue to help us grow in the future. In addition to our greater portfolio of online programs. All of that has helped us reach this growth.
Regarding undergraduate student dropout, the average is stable. Dropout of high on-campus content or high on-site attendance is coming down because of many initiatives to gain efficiency in processes. But also, let me remind you, this is only the second quarter, so we are showing you the dropout rate by the midpoint of this semester, that is at the end of the first quarter. We usually have a higher dropout rate at the end of the year. Anyway, this is an extraordinary number and we hope to keep it in the third quarter, which is of course much more challenging. Now on slide six, let us talk about our net revenue. In the lower chart, you can see our net revenue evolution.
It's been a number of quarters that we announce that the revenue growth would be slower, and then it will reach a point of inflection. In the first quarter, we had -4.9%, second quarter, -3.4%. The point of inflection will be in 2023. I mean, this is what we announced. Looking at our performance now in the first quarter, we believe we will begin to see revenue growing already in the fourth quarter this year. We are very happy with this. On slide seven, talking about average ticket, I think this is a topic that always receives a number of questions from analysts. Now, when you look at freshman year, we see a big supply. We do not have a lot of control on the average ticket for freshmen.
We are not engaged in a price war. We try to maintain our prices. When you compare 100% digital in the previous trade cycle to the current trade cycle, we can see that our tickets have remained stable. Of course, maybe we did not have as much volume as we could, but this was our strategy to maintain the average ticket. Now, because we have more students on premium distance learning, we have this impact on the average ticket. We believe that the best view of average ticket is to work on the opportunity to leverage our operating results so we can gain more scale on digital products. Basically, the programs that have a higher digital content, every new student you have in the system, you have a lower cost per student.
Because digital programs, they have a fixed cost, and a variable cost for every new student is much lower than those programs when you have a higher on-campus content. Since you can maintain the same cost on digital programs, your margins tend to grow in time. That's why our strategy has always been, and if you look back, it's been five trade cycles that we've been talking not only about the volume, the number of students that have enrolled, but we also compare the revenue from one trade cycle to the previous one. Because we see that every trade cycle, we have more operating leverage. This is what you see on slide seven to help you understand this. The average ticket, looking at freshmen, this is a competitive market, as I mentioned. We, as I said, we keep stable prices, but this is a competitive market.
There's not much we can do, but of course, we can gain scale. We're trying to increase the number of freshmen to have a higher revenue. Because the variable cost for digital products is very low, it means that in time we'll have a higher profitability. This is our strategy. The average ticket of out-of-pocket students had a drop from BRL 652 in the first quarter 2021 to BRL 635 in the first quarter 2022. If you look at the revenue, it has grown 12.4%. The average ticket had a drop, but the volume is growing. Again, it means that our revenue on low on-campus content has grown 8%.
That is comparing apples to apples, so higher on-campus content, comparing two trade cycles so that we have a fair comparison for the average ticket. This is what is happening, and this is result of our product mix. The final highlight here, if you look at the press release, you will see we have lost Fies and PAP students because they're graduating. They had, historically, higher average tickets, and so you see this impact because of the mix, adjustment. It used to be 12%, you know, the share of these students is now 7%. We have the inflation of payroll and also operational costs, and we are working on it to. Otherwise, the impact would be much greater. We know that PDA and marketing have contributed.
I think that an important thing to highlight here is the growth of our EBITDA margin, even when confronted with this scenario.
Many times we get questions about our PDA and whether the PDA reduction is reflected in extraordinary expenses. We wanted to show you year-on-year that we had 18% last year. It's now down to 13%. It was 13% in the first quarter. The percentage of net income is lower and we understand that PDA as a proportion of net income is stable. That's why our payments are now more stable. These are not related to anything but a more efficient operation. Now, helping us with margins, we have been working on to reduce our acquisition costs, and this is reflected in the contribution of marketing. Now moving on to slide number nine. Just a quick comment in relation to our accounts receivable. To the right, if you consider the out-of-pocket accounts receivable, it's been dropping.
Even though the out-of-pocket is growing, our PDA in that regard is decreasing because our students now have more payment ability and the average term of receivables has spiraled down. We had a reduction of over 16 days. We're now at sixty for the average time of receivables. Going back to the left side of the slide, you can see that total account receivables is now stable at BRL 5 million, with slight growth from PMT and PEP. This is only natural because of the maturing cycle of PEP students. We know that we are not enrolling new PEP students for several trade cycles. Of course, there is an evolution semester by semester because this is only natural.
I think that the highlight here is not, you know, accounts receivable is no longer a problem for us. We're feeling very comfortable about the results we have achieved. Now, closing slide ten, Kroton Med is a very important segment for our strategy. We have an organic growth plan with maturity at over 850 seats. Today we have 556 medical seats, so there's still room to mature organically. I think that we have to underscore the growth of revenue in the first half. Here we had growth of over 30% showing our strength to grow organically. We announced guidance for the market during our Cogna Day, and we have surpassed it both in EBITDA and revenue. 50% of the year is now spent.
We have surpassed 50% of the guidance and 54% of EBITDA. We know that the second half of the year always has greater numbers of students enrolled, so we will exceed the guidance given, and we're feeling very confident about this vertical, which is one of our top growth opportunities. With this, I close Kroton, and I'll hand it over to Mario Ghio, Vasta's CEO, for his presentation.
Thank you very much. I would like to start our presentation talking about the operational data now at the close of the semester, which is when we have the basis of schools and students. We close with over 1.1 million students using our core products and approximately 5,400 partner schools. The use of complementary content represented an addition of 100,000 students to our base.
We have now 400,000 students that use at least one complementary content solution, reaching 1,300 schools in those complementary solutions as well. Since the IPO, we have taken several initiatives to expand our sources of revenue, launching new products and solutions. I would like to mention that we have now concluded the integration of the Eleva Learning System. We are now putting into operation our Fibonacci Learning System and signed a distribution agreement with McKinsey. As for our complementary solutions, while they were expanded, our portfolio is now more robust. I would like to mention that we have moved into the B2B2C segment with the launch of Plurall Mil Prof and Plurall Adapta for private tutoring. Very soon these lines will be more significant to our revenue.
In digital services, we look at the schools and institutions that need to have their operations upgraded. We have added several brands, such as LM and Fidelis, to our portfolio. With the goal of meeting the demand of our partner schools, and especially in this quarter, we took a very significant step forward. As we announce our minority investment that will be consolidated, in our net worth results with the investment of Eduk Bank. Eduk Bank is very important for us because it ensures predictability and recurrence of revenue. We believe that Eduk Bank together with Fidelis, which is our ERP system, those will be very important tools to boost the efficiency of our schools together with their profitability. We know that there are around BRL 70 billion in this market and in our estimates the partner schools of Vasta now have been acquired BRL 17 billion.
This is the tuition volume that Eduk Bank could provide if all schools were reached through this partnership with Vasta. In the next slide, 13, I would like to talk a little bit about our net revenue. We grew 35% approximately reaching BRL 190 million in the quarter. Year to date from the fourth quarter last year to the second quarter this year, we grew to BRL 960 million in net revenue. This is significantly higher than the previous period. Here we have subscription products with BRL 450 million in the cycle, and we have recognized a little over 85% of the ACV that has been converted into revenue. We are feeling confident that all the rest of this ACV will be converted in the next semester.
Now moving on to slide 14 to discuss ACV conversion. As I said, more than 85% of the ACV has been captured and has been transformed into net revenue. We have a different seasonal impact because Mackenzie, for example, has more revenue in the second semester. As such, we will have less concentration. With the growth of Mackenzie in the following years, we will have a semester that will be a little heftier than the previous semesters in the previous cycle. Therefore, we have less concentration in subscription revenue when compared to previous cycles. Now, for the next semester, we expect that the additional 14.5% of ACV will be fully converted into revenue at the close of the cycle ending on the third quarter.
From the fourth quarter on, we will have the ACV for 2023. Now looking at EBITDA in slide 15. In the recurring cycle, EBITDA grew 68%, totaling a little above BRL 990 million with margin growth of 7.4 percentage points. We credit this expansion of margin from net revenue growth, but also to the efficiency gains in our financial discipline and also our integration with Eleva, exploiting our synergies and improving our line of costs and expenses. By the way, our cash generation reached BRL 103 million in the second quarter, and we were able to reverse our cash generation losses in the comparison.
This substantial improvement in cash generation comes from the improvement in EBITDA and our receivables and a reduction in the PDA of schools that have now neared historical levels and of course, the contribution of our working capital. Thank you very much for your attention. Now I'll hand it over to Fred Villa.
Thank you very much, Ghio. I will start my presentation on Saber on slide 17. Speaking of the main financial highlights, here we know that Saber benefits from the National Textbook Program, and Red Balloon also represents around 50% of our revenue. In the quarter, we had a reduction of revenue of around 19% and in the semester around 8%. Well, in spite of the growth that we reported in Red Balloon, we saw new schools being added, approximately 8 of them.
There was also expansion in the student base. Revenue grew in Red Balloon, but there was a reduction in revenue obtained through the National Textbook Program. This was by reason of the greater seasonality of the National Textbook business calendar. The reflection was felt in our recurring EBITDA and margin. There was a reduction in EBITDA in the accumulated semester. EBITDA reached BRL 29 million in the first half and in the second just 22. A reduction of 22.6% that is explained by the seasonality of the National Textbook Program, as I explained. Just to close the presentation on Saber, we now move on to slide 19 to speak about Cogna. Here I start with the main financial indicators, net revenue and recurring EBITDA.
Looking at the quarter and semester, I think that the key message here, last year we said that 2022 would be the inflection point and for Cogna's revenue growth. In spite of the fact that we are flat in revenue growth at 0.2% in the quarter, in the semester, we observed 3.3% growth, reaching BRL 2,332 million. In the semester, the growth is explained by everything that Roberto Valério and Mario Ghio said, the evolution in Kroton. Well, there was a positive cycle and growth was very significant in Vasta, growing revenue at 34%. Now, moving from net revenue, where we have positive news in the semester, we look at recurring EBITDA and margin.
In the second quarter, EBITDA grew 11.4% and margin reached 30.7%. In addition to revenue growth, we see the effect of our efficiencies in our business. In Kroton, there was an improvement in delinquency rates that is reflected in PAD, PDA. Here, in terms of corporate expenses, there was a reduction of around 9%. This, of course, boosts our efficiency. For the fifth consecutive quarter, we post growth in EBITDA. I think that the most important message is the one we see on slide 20. We have reinforced in recent conference calls the importance of our operating cash generation.
On the slide to the right, from the first semester, 2021, in this comparison, which is the best way of demonstrating this, because as you probably remember, there was a mismatch with the anticipation of receivables in the first semester, 2021. In the semester, we have reached BRL 291 million with growth of 47%. In the comparison from the first half, 2021 to 2022, our operating cash generation from 0 in 2020 reached BRL 291 million. The focus, of course, for the coming semesters will show that the improvement in the quality of our students will lead to very positive delinquency rates at the level of today. Now moving on and finishing Cogna's presentation in slide 21, we take a look at leverage. Our leverage ratio is under control.
As you can see on the upper part of the slide, our net debt over adjusted EBITDA is shown as an evolution. In the last five quarters, while we went from leverage of 2.13, we are now down to 2.09. Remember that we had an interbank interest rate at the time of around 3% at that time, and now we are over 13%. Our focus on operating cash generation has paid off. We have been able to maintain our leverage flat. Now, looking at the debt composition, our company finishes the first semester with BRL 3.7 billion in cash and cash equivalents, with a reduction of BRL 3.1 million in net debt.
To the right, we see a chart showing that in the month of August we will have an amortization of approximately BRL 2 million. The company reinforces the message that with the current cash and operating cash generation that we have seen in the last quarters, we will be able to amortize our debt in the short and medium term. We emphasize now that at the end of the second quarter, some initiatives and considering the increase in interest rate, we have bought back some of our debt below par. We also had issuance of approximately BRL 500 million with an average lower cost than the last debt raise in 2021 and with the lengthening of our debt profile. The message here is that leverage and debt are both under control in the company.
With this, I close on slide 21 this brief presentation, and I'll turn it over to Mr. Valério for his final remarks.
Thank you very much, Fred. Moving on to slide 22. I think that the first point I would like to highlight is that Kroton had good retention and enrollment results. We believe that the inflection point for revenue will be anticipated and we can expect growth of revenue still this year with the resumption of growth in Kroton. Both the growth team and the customer experience teams in Kroton have worked very hard to make it a reality. We're feeling very excited about it. Secondly, something I have said is that the reduction of delinquency rates is the fruit of our labors in the student base, both in enrollments and re-enrollments.
We were able to cleanse our base and this will take us to a new PDA over net revenue ratio. This is another important factor. Together with revenue growth, we have a new perspective for PDA. All of this shows that we have solid operating and EBITDA margins. Looking at recurring EBITDA margins, the outlook is positive. Cautiously positive because of the current situation in Brazil. I think that the tough times for Kroton are in the past, and we'll continue to make advances to deliver everything that our teams can. In Vasta, I think what Ghio has mentioned show our strength in Vasta, our competence and our ability to deliver. In 2021, Vasta was affected by the pandemic, but this is now in the past.
Growth is coming on very strongly, both in learning systems and also on this focus on subscription. All of the restructuring conducted by Mario Ghio is also driving growth of margin in a perennial way. It's not something that's only short-term. Diversification through several initiatives also shows our commitment to continue to offer new solutions to our schools. This is just the early days of a new cycle of ideas, and we're feeling very optimistic about Vasta in the near future. Adding up the two organizations, while this would represent around 90% of the company's results. Because of this, we're feeling very excited about the future. In Cogna, in 2021, we had to pursue our profitability or this resumption of profitability.
During Cogna Day, we said that we needed to improve our profitability and at the same time make improvements in revenue growth. Vasta is delivering this, Cogna is about to deliver this, and all of this shows that our strategy is coming to fruition. With the increase of our interest rates in Brazil, we have to take some countermeasures. Fred did a great job. He has mentioned two aspects in the buyback for the quarter, and there are other initiatives underway. Everything with the purpose of reducing the debt service. The final message in terms of leverage is that we are at a healthy level under control. Our cash generation is more than enough to pay off everything that we need to amortize in our debt and to continue growing.
Just before I conclude, I would like to reinforce that the IR team will be happy to answer any of your questions. We'll be opening now for the Q&A. Both the presentation and all of the information have been posted to our website. If there is anything that we are unable to answer to you here during the conference call, you can go and look up that information.
Ladies and gentlemen, we will start our Q&A. To ask a question, please press star one. To remove your question from the line, star two. Please hold as we collect the questions.
Our first question comes from Luca Marchesani, Itaú BBA. Please, Luca, you have the floor.
Good morning, everyone. Thank you for taking my question. At Kroton, looking at marketing expense, there is a trend of more investment on advertising for student intake, but we see stability compared to last year. Can you give us some more color on your strategy about marketing? Can we consider this level as stable for the future? Thank you.
Hi, Luca. This is Roberto. Thank you for your question. We have focused on a number of initiatives, many of them focusing on more digital, that is more online than offline. We have more assertiveness to measure results by doing that. We'll continue to focus on that. Also, the investment team wants to broaden our distribution, increasing our sales capacity in smaller towns.
This of course will have a lower cost because it is usually a lower cost to penetrate smaller towns. Of course, I am not going to talk about our strategy because the competition may be listening to this conference call. Our strategy is to maintain stability in marketing expenses. Probably I would say that it can even grow a little bit, you know, on marketing expenses, and I can tell you why. Our LTV on CAC ratio is already above 5x, and we believe this is already optimum. We could in fact invest a bit more in marketing to bring more volume. You know, answering your question, on practical terms, today's level will remain stable. Maybe we will spend a bit more in the future, but there will be no big difference. You know, we're focusing on margin.
As you know, we believe we have room to invest a bit more in marketing to bring more volume. Remember, this is a highly competitive market. A lot of what we do is try not to burn money in marketing in times when the results will not be so favorable in terms of volume growth. Thank you for the question.
Perfect. Thank you.
Our next question comes from Marcelo Santos from JP Morgan. Marcelo, you can ask your question now.
Good morning, everyone. Good morning, Valério, Ghio, Fred. Thank you for taking my questions. My first question, can you share your view on your intake strategy for the second half of the year? How much you've invested and what you expect? Second question. You've mentioned average tickets for higher on-campus content or lower on-campus content. You mentioned there will be continued pressure because of the product mix.
When will we reach stability? When do you expect we reach stability in that?
Perfect. Thank you. I will answer your questions. Thank you for your questions, Marcelo. Talking about student intake, we are in the middle of the trade cycle. Classes began last week, so it is only natural that we will have an acceleration of enrollments when classes begin. Many people leave that for the last minute, so we are prudently or cautiously optimistic. In both segments we're growing student intake, both in high on-campus content as well as in low on-campus content. Because, you know, July and August were months when the enrollments lost momentum, obviously because of the economic context in the country. We are still growing on both segments. This is a game that may change every minute. I mean, we have another 45 days of student intake, but we feel cautiously optimistic.
All right, Marcelo. Regarding the product mix change, everything related to mix takes a while, you know, for the change to consolidate because of our grade cycles. You know, we have graduations every six months and new enrollments every 6 months. Graduation time is usually ranging between 3-4 years. A student coming in today will graduate in 3-4 years. I would tell you that considering our strategy for ACV that began a year ago, we will need another two years or maybe 4-5 cycles to see the full reflections, the full impact of these initiatives. Maybe a bit shorter, we will see more impact, you know, every quarter, every semester. That's my view.
Final point. The student intake has already stabilized, so now we need time to see that reflected on the student base, right?
Is that how I can read your answer?
Yes, I think it is a great interpretation of my answer. Actually, even better explanation if you consider student intake and then the distribution between lower on-campus content and higher on-campus content. We believe that higher on-campus content will accelerate further. We expected that, and it is actually accelerating at the expected pace. When you look at 100% digital and once a week model, that is more stable. You know, that has been stable for a number of cycles now. Your interpretation is correct.
Thank you very much.
You're welcome.
Our next question comes from Pedro Lima from BTG Pactual. Pedro, you may ask your question.
Good morning. Good morning, everyone. On our side, we have two questions. The first is about the PDA levels.
We have seen this improvement, you know, after you've taken some initiatives. This number 13%, is that the recurring level you expect to have, you know, that you consider healthy? Can you provide some more color on the initiatives that led to the improvement in receivables? Because, you know, the PAP reduction for PAP students who no longer have an intake. There was also a change in the format of the National Textbook Program. This was my first question. The second question is about Kroton Med.
You have started that more recently. Are you looking for a strategic partner or do you believe in the future you may have an IPO? What's on your radar? Thank you.
Thank you, Pedro. Fred, would you like to answer about PDA?
Yes. Your first question about PDA. We believe our current PDA level is right. As you know, as the market knows, we made a change in the end of 2020, and we believe this is the right criterion. Looking ahead, I believe we have shown in the presentation, you know, Valério spoke about that, and the best way to view that is PDA on net revenue. For four quarters now, we've kept it at 13%, and that's what we believe will continue. I mean, we may have a slight variation up or down, but this is the right level. Our PDA, you know, after we had this change in 2020, it is closely related to cash generation. We see an improvement in PDA because we had an improvement in delinquency levels.
We do not disclose these numbers because our competitors don't disclose that number. We were talking about this percentage of PDA over net revenue, which is the number we use for management. This is what I can expect for the future. On student intake, we have made improvements in the level of student credit, so we now have students who are more financially sound and more focused on cash. You know, we had a number of internal initiatives to improve operating cash generation and collections. My final message is that, yes, our PDA is managed at this level, the 3%.
Okay.
Pedro, you also asked about PMT. We discontinued that for freshmen in 2019, right? We did not have student intake, a PEP student intake in 2021, 2022.
We only have a few PEP students already in the student base about to graduate. PMT, we made a change from the first to the second trade cycle of 2021, because in the past, it was paid at the end, you know, as the students graduated. Today, students pay monthly. They make monthly payments, and so that improves our receivables because they're already paying. It's less, but they're already paying for that during the program.
About the Kroton Med, as I mentioned, we are growing robustly in Kroton Med. We're growing organically, and I believe we will reach a maturity point above 800 places, above 800 students, so we still have room for organic growth. This is a good segment. It's a good business. We prepared the company. We made a carve-out. We already have, you know, independent reports.
The company is perfectly prepared for us to adopt different business models, you know, in terms of the organization chart. Now, looking at our current leverage, we have enough cash to make, you know, small acquisitions on the medical front. Because this segment has opportunities, maybe, yes, if we find a good match, a good financial partner who can make the investments that we deem correct, because we don't really need capital. The idea is not to capitalize Kroton Med to change our leverage. No. We want Kroton Med to grow more, I mean, to grow faster in medical programs, especially because organic growth can continue for a number of years, but we are in no hurry. About IPO for Kroton Med, we're very far from that. You know, this is a company that has to continue to grow.
We're very far from an IPO. I think that's it. I hope I've answered your question.
It's very clear. Thank you, sir.
Our next question is from Victor Tamietti, Goldman Sachs. Victor, you may ask your question.
Good morning, everyone, and thank you very much for answering our questions. We have two questions, in fact. Could you please elaborate on the higher CapEx level and investments in expansion that we saw in the semester, and what can we expect for the second semester, second half? With the sale of schools at the end of last year, and also going back to medical, how do you view the space for pursuing strategic alternatives for other business areas at Cogna? Do you consider closing Vasta's capital, considering the current valuation and your trust in its business potential?
Thank you very much, Victor, for the questions. I will hand it over to Fred to answer about CapEx, and then I will continue.
Thank you very much. Fred here. Your question about CapEx growth. We have invested in content and also in IT. This increase of around 13% in expansion resulted from the purchase of learning books at Vasta, a very innovative solution for Vasta's activities. It's important to mention that this was just a transfer or a dislodgement. When we look at Vasta as a whole, we see that CapEx in the year is very close to what we delivered in 2021. There will be a gradual reduction in CapEx in coming years, in the near future, because we are also investing heavily in technology. By the way, in 2021 we delivered our new system, the SAP. In 2022 we are also participating in a transformation program that we call Student Focused Transformation Program.
This is where the increase resulted from. It's a one-off increase. This is a line that will be correlated to what we delivered in 2021, and that there will be a gradual reduction.
Thank you, Fred. In relation to alternatives and other business areas to drive our growth, I think there are several fronts. We have our innovation hub. It can be used for the discovery of other educational segments and also careers. Those are premises, and these are projects that will mature more slowly. We have a platform for young adult education. We'll be launching in the third quarter both the digital account and other platforms. Those are initiatives. I can mention two more examples. Ampli, our product for mobiles and techs, which is a technology free education program. It's now running on beta.
There are several initiatives going forward. We have several options. Considering our size of BRL 5 billion, of course it will take a while to mature some projects, at least two or three years. We are keeping our eyes peeled to see any opportunities. There is nothing very relevant in the short term. As for Vasta, we have no intention of delisting it. Vasta is a fast-growing company with lots of opportunities in the future, so we continue to believe in the thesis that led to its IPO.
Thank you very much.
Our next question is from Pedro Caravina, Credit Suisse. Please, sir, you may proceed.
Good morning. Can you hear me well?
Yes, we can.
Thank you. Two questions.
First of all, could you comment on the outlook for the new DL programs, law and psychology, in relation to the ticket, the average ticket? And what about your deleveraging plans? What can we expect in that regard?
Thank you very much, Pedro, for your questions. Well, I will talk firstly about DL. Well, law and psychology are two programs that we applied for with the Ministry of Education a long time ago. It's a lengthy process to get the approvals from the Ministry of Education. The go-to-market is ready when everything's ready. We're still expecting the approval for DL program, so I cannot give you any more info in terms of possible dates or anything. Just to let you know that whenever we get the approval and authorization for the programs, everything's ready for implementation.
Thank you. Fred here.
About your question. I think it's important to mention that next week we'll be amortizing BRL 2 million. This is part of our payment schedule. Well, we have several initiatives. We have bought back 347 papers that were below par. This is an initiative that adds value to the company. We also had issuance of BRL 500 million to lengthen our debt profile at a lower capital cost than in the past. Several other initiatives are being conducted, but most importantly, operating cash generation in the company is positive because of our operations, and we are open to opportunities. In the next quarters, you will be able to see in our financial performance the effect of these initiatives that we are currently involved in.
We believe that probably there will be reduction semester-on-semester as a result of the operating results. After the election, there will be also a gradual reduction in leverage.
Thank you very much. Very clear.
We have closed our questions and answer session. Let me now give the floor to Mr. Roberto Valério for his final considerations. Please, Mr. Valério.
Well, I'd like to thank you all for having joined us in this conference call. I could see you had a problem, you know, for those who have, who were in the meeting in Portuguese through the webcast. Those of you who have missed a portion, it will be available in a few minutes on our website. One more time, thank you. Congratulations to our teams at Vasta, Cogna, Saber, and I'll see you in the next quarter. Thank you all very much.
Today's Cogna conference call is now closed. We thank you all for joining us. Have a great afternoon, and thank you for using Chorus Call.
