Earnings Call Analysis

Sales Exceed Expectations; Commission Stabilizes

Last year ended with high sales concentration, significantly increasing commission to distributors in the U.S. beyond the typical 30%. However, with new distributors on board and a broader customer base, commission rates are realigning closer to the 30% norm. Sales of the product CERAMENT G have outperformed expectations; the clinical feedback mirrors European study results, assuring both surgeons and the company. In the U.S. market, there has been minimal resistance to the product's pricing, indicating strong value recognition. Also, it's noted that customers, including private and public hospitals, reliably pay, suggesting financial stability in receivables.

Impressive Growth and Profitability Amidst Product Expansion

Bonesupport showcases a remarkable quarter, reporting sales of SEK 140 million, a staggering 88% year-over-year growth with constant exchange rates reflecting 75% growth. The company delights in its profitable stint with an operating result of SEK 14 million, a substantial improvement from the previous year by over SEK 23 million. This performance is backed by the triumphant ongoing launch of CERAMENT G in the U.S., noticing a quarter-over-quarter sales increase by SEK 16 million. Product upgrades and robust clinical study results further amplify the positive narrative within the quarter.

Market Dynamics and Expansion Strategies

Strides in the U.S. market are impressive with a 126% year-over-year growth and a 107% growth after adjusting for currency exchange impacts. The strategic moves hint at some cannibalization between products but maintain overall robust growth. On the European front, the sales climb by 28% year-over-year, with a constant exchange rate increase of 24%, marking a steady recovery, albeit challenged by healthcare staff shortages. Amid these developments, Bonesupport continues to focus on structured data collection and studies to uphold its clinical efficacy narrative.

Maintaining Strong Operational Margins and Growth Trajectory

The financial breakdown from CFO Hakan Johansson reveals a continued strong gross margin at 94.5%, underscoring the company’s operational efficiency. Although sales expenses have risen, largely due to expanded U.S. operations and medical education investments, the net impact remains positive with a reported operating profit of SEK 6 million compared to a loss the previous year, indicating a resilient growth trajectory.

Clinical Validation and Long-Term Impact

Bonesupport's advancements aren’t solely in revenue numbers; the clinical front beams with success too. Studies highlight the use of CERAMENT G and V in successfully avoiding amputations in diabetic foot ulcer cases and demonstrate the profound long-term benefits of CERAMENT G in open trauma fractures with significantly reduced infection and amputation rates over a 4.5-year period.

Outlook and Future Endeavors

The company closes with confidence about the future, citing a 72% growth rate in constant exchange rates in the first half of the year. With a unique market position as the only FDA-approved antibiotic-eluting bone graft, Bonesupport is poised to capitalize on favorable market dynamics and continuous innovation. A Capital Markets Day is on the horizon, promising a deeper dive into the company's journey and strategic initiatives.

Earnings Call Transcript 2023-Q2

[Operator]

Welcome to Bonesupport Q2 Report 2023. [Operator Instructions]Now I will hand the conference over to CEO, Emil Billback and CFO, Hakan Johansson. Please go ahead.

[Emil Billbäck, executive]

Yeah. Thank you, operator and welcome everyone to beautiful morning to the Bonesupport Quarter two 2023 call. My name is Emil Billback and sitting next to me is Hakan Johansson, our CFO. So we'll use the next 25 minutes to guide you through the presentation of the first results that we released this morning in the quarter two report and then we will open up for a question-and-answer session.So before I go into the presentation, we would like to draw your attention to the disclaimers that we'll cover any forward-looking statements that we might do today. So let's get right into it and I would like to begin the entire presentation with some condensed highlight from the report. And of course, we're very pleased to report the quarter two sales of SEK140 million. This corresponds to a reported growth of 88% year-over-year and in constant exchange rate, the growth rate was 75%.The operating result before incentive provision was SEK14 million. This is a profit improvement versus the same period last year of more than SEK23 million. The reported EBIT was SEK6 million, which marks now our second quarter as a profitable company. The main highlight of the quarter was, of course, the ongoing launch of CERAMENT G in the U.S. We saw an increase in CERAMENT G sales of SEK16 million quarter-over-quarter, with surgeons using CERAMENT G on a broad set of applications within the indication and a high level of pilot used in the quarter.So we are continuously improving our products and the user experience. And in the quarter, we announced the launch of the next generation of CERAMENT G, which increased ease of use and also reduce environmental impact. In the quarter, data from long-term follow-up, meaning 4.5 years after using CERAMENT G with open trauma fracture published, so I will cover all of these topics later on more extensively in the presentation, but let's first look at the sales development, we go to the next slide.This is one of our standard charts for the quarterly report and investor presentation. It shows last 12-month sales in Swedish currency and it shows every quarter since quarter two 2016, split by region and product category. Sales is taking off really well with the largest driver being CERAMENT G in the U.S., reaching sales of SEK51 million in the quarter. In Eurow, the antibiotic-eluting CERAMENT, which is the CERAMENT G and CERAMENT V combined, sales grew with 32% in the quarter versus last year.We conclude that a note that we make market share gains on other therapy options, mainly autograft and bone cement on almost all markets in Eurow. See a general improvement in surgical volumes across all geographies. In Europe, we have to summarize it's still behind pre-pandemic levels in terms of surgical volumes. There's some emerging cannibalization between CERAMENT G and CERAMENT G BVF in the U.S., and I will share some more details about this also over the next coming slides.So let's start now with the U.S. and go to the next slide. So in the U.S., sales of SEK104 million in the quarter, which corresponds to a growth of 126% year-over-year at constant exchange rate the growth would have been 107%. Sequentially, growth was 21%, meaning the growth in quarter two versus what we reported in quarter one, 2023. We're starting to see some cannibalization as I mentioned before between CERAMENT G and CERAMENT BVF. But despite this, CERAMENT BVF in the U.S. grew 14% in the quarter versus quarter two last year.In fixed currency, the growth was 8% for the first six months of 2023 on CERAMENT BVF. So this can be compared to the growth that we saw in the second half of 2022 when CERAMENT BVF grew with around 40% in constant currency. So the difference between these two numbers is, of course, partly attributed to the cannibalization effect of CERAMENT G.So let's go little bit further into details on CERAMENT G, which we prepared on the next slide. So we're on Slide 6. With this quarter sales of SEK51 million, we can conclude that the quarterly sales of CERAMENT G is that we have in the U.S. is now actually larger than our entire European sales in the quarter. I believe that this shows the large unmet need, but also the efficiency of our commercial structure in the U.S. and also the huge potential that we're tapping into.Our hospital approval process is progressing well and we have added some 10 approvals since quarter one. Among the added approvals in the quarter are the very large [ Atrium Health ] and the prestigious Stanford Health Care. Thus, so far, we have signed some 60 out of the approximately 420 hospital groups covering in the U.S. and we must say we've been off to a very good start with approvals. And now and in the most recent period, focus is on securing implementation and driving account penetration where approvals have been given.Educating and training the orthopedic surgeon and the hospital staff is part of the contractual commitments when introducing a breakthrough therapy device like this. This is also an essential part of creating therapy ambassadors among the surgeons. The amount of pilot users which perceives approvals and continuous use was high during the quarter. I have shared with you before that the performance and the market penetration of a completely new product like this goes in waves, go stop go as it's called in the orthopedic industry.We continue to get positive feedback on the product handling and the transition especially to a one-stage procedure. All in all, care takers and hospital administration see clear and visible clinical and health economic benefits, very similar to what has been previously displayed in various clinical studies.In order to systematically build a database of experience with CERAMENT G and also consolidated patient data, we're starting a structured collection of data a so-called registry study on the use of CERAMENT G in the U.S. We're now selling in 38 states and during the quarter, we saw our first CERAMENT G order from OrthoPediatrics.OrthoPediatrics have been successfully selling CERAMENT BVF to pediatric hospitals and they are now adding CERAMENT G to this customer segment. Several layers of data has been processed regarding the ambition to get label extension for CERAMENT G in the U.S. to also include prevention of infection as an example related to open fractures. The last batch of data has not yet arrived from the university hospital that we have partnered with, so with previous insight and knowledge of the time it takes to analyze and process such amount of data and also to put it together into a submission, we have moved the target date for the FDA submission to the end of quarter four this year.Now let's turn to Europe, go to the next slide, please. So in Eurow for the quarter, we saw sales of SEK36.5 million and this corresponds to a growth of 28% year-over-year and 24% at constant exchange rate. We continue to see a steady recovery in general surgical procedure volumes. However, healthcare staffing shortage remain a challenge and we will continue to pose a challenge in quarter three as strained healthcare workers will try to manage during the European vacation season.For the third quarter, we thus expect certain accentuation of the normal seasonality. In the quarter, we announced modifications to the CERAMENT G. This was the third major upgrade to the product, so we called it the third generation, even though the change not may be that dramatic. So let's take a further look on what those changes actually are? So we're on Slide 8.So important to note, first of all, is that there's no change to the formula, the composition or the mechanism of action for CERAMENT G. There is no change to the active ingredients, but all the components for mixing and applying CERAMENT G now comes in one surface sterile tray. For those that have been in a surgical theater, you know that every component must meet requirements of the different and specific surgical zones in the theater. The improved handling and the reduced waste are factors that will matter a lot to the staff performing the surgery, as well as to procurement officers and of course to our continuous sustainability work. We'll go to the next Slide.So continuing on the highlights, we are constantly assessing the organization in perspective of overall ambitions and deliveries. We've decided to change how we lead our efforts of indirect markets and that means the distributor markets in Europe and the rest of the world and also the European hybrid markets. And we set up a new structure here. We've also, in the quarter, done some organizational upgrades and the changes that I'm mentioning now were required in order to take our performance to the next level.However, these changes have triggered severance cost and other expenses in the quarter of about SEK3 million. Changing the structure like this and upgrading the organization is, of course, part of running a fast-growing company, but to the magnitude we saw in quarter two I think this has to be considered as non-recurring cost, of course.So also in the quarter, there were two really important studies that were published. The first one studied by Kavarthapu et al. from King's College showed strong results on infected diabetic foot ulcers that were treated with CERAMENT G or V and all patients in the study were able to avoid amputation.From the University Hospital of Manchester, [ within short ], Henry et al. followed 81 patients with open trauma factors for a median of 55 months, confirming excellent and sustainable benefit from a single-stage procedure of CERAMENT G. So on the next Slide, just looking a little bit further on what the patients look like that were part of the trauma study by Henry.So this picture shows the open trauma fractures and how they're assessed on a scale from one to three in terms of severity. And the study from Henry et al: was made on 81 patients in category 3B and you see the categorization there with a red square around it. This means that the bone is really in fragments and that there is material soft tissue damage.Several previous publications have shown infection rates on these category of trauma fractures of up to 52% and then amputation rate of 16%. In the study, the infection rate was 3.7% and the amputation rate dropped to 3.7% as well. And this is when the patients were followed for 4.5 years. This is the longest follow-up data ever published on use of a synthetic bone graft on 3B open trauma fractures. So very strong results also clinically delivered in quarter two.And with that, I leave over to Hakan to do a bit more of a deep dive in the numbers.

[Håkan Johansson, executive]

Thank you, Emil. So let's jump to Slide 12. So net sales improved from SEK74.6 million to SEK140.4 million, equaling a growth of 88% or 75% in constant exchange rate. Emil has already spoken about the strong performance in the two segment and the major drivers behind the sales acceleration. So let me comment on the currency.Changes in currencies measured in year-to-date averages in 2023 versus last year had a positive impact of in total SEK9.6 million, of which SEK8.6 million relates to a stronger U.S. dollar. The depreciation of the Swedish krona versus other currencies also drives expenses as you will see on later slides. So let's move to the next slide.The contribution from the segment North America improved SEK24.6 million and was reported to a regional contribution of SEK31.7 million. The improved contribution relates to increased sales after effect from increased costs. Sales and marketing expenses during the quarter amounted to SEK65.4 million compared with SEK34.8 million previous year, of which sales commissions to distributors and fees amounted to SEK36.7 million compared with SEK16.7 million in the same period last year.The increase of SEK10.6 million excluding commissions and fees was driven by currency effects of SEK2.3 million and the remainder from an increased activity level. As we have announced previously, the U.S. Booster positions are up and running and there is a strong focus on medical education and increased market presence also contributing to the cost in the quarter.The contribution was also charged by R&D cost related to studies of SEK1 million in the quarter, same level as previous year. From the lower graph showing net sales as bars and gross margin as the orange marker, it can be noted that the gross margin is remaining strong and reported to 94.5%. Sales to other orthoPediatrics in the period impacted gross margin negatively in comparison to the first quarter this year.In Europe and Rest of World, a contribution of SEK7.6 million was reported to be compared with SEK7.1 million previous year. The improved contribution relates to increased sales after effect from increased costs. Sales and marketing expenses increased with SEK6 million and was driven by currency effects of SEK2.3 million, but also attributable to fill vacancies and to a generally higher level of market activity.From the lower graph and the orange marker, you can see an improvement in gross margin compared with the first quarter this year, following an improved market mix. As mentioned in our quarter first report, we have a minor increase in manufacturing costs, the lateral is anticipated to be mitigated by increased sales prices having gradual effect during the remainder of the year. In the period, finally, we also had nonrecurring cost impact in sales and marketing in North America and Eurow with altogether SEK2.9 million. So let's move to the next slide.Selling expenses increased with SEK17.6 million versus last year, of which SEK3.3 million relates to currency FX and SEK2.9 million in non-recurring costs. As we mentioned before, the U.S. Booster is up and running and we continue to see results on top line. In Eurow, we increased early in the year with two headcounts on the sales side and our total Eurow commercial organization is now 30 people.The increase in the quarter relates to a ramp-up in activity level of congresses, medical education and, of course, the launch program for CERAMENT G in the U.S. R&D remains largely in line with previous year, but was picking up from a low Q1 this year and administration remaining on a stable level, excluding effects from the long-term incentive program, equaling SEK12.2 million compared with SEK10.9 million previous year and SEK11.7 million in previous quarter.Next slide, please. The operating profit was reported to SEK6 million compared with a loss of SEK14.9 million for the same period previous year. SEK20.9 million improvement following a strong sales performance. The profit also includes expense provisions regarding long-term incentive programs amounting to an expense of SEK7.7 million this year compared with SEK5.8 million previous year. Of the total cost of SEK7.7 million in the period, only SEK0.2 million is cash flow impacting in the future.The operating profit improvement before the long-term incentive programs was SEK22.7 million, confirming a strong underlying positive trend. The increased provision for incentive programs in the quarter relate to the strong share price appreciation in the period. Cash flow in the period was impacted by the strong growth, resulting in an increase in accounts receivable of SEK51.1 million.And with this, I hand back over to you, Emil.

[Emil Billbäck, executive]

Thank you very much, Hakan. So let's wrap up this presentation. So we're, of course, very pleased to present such strong quarterly results and we believe this is more than confirming the high expectations on what CERAMENT can do to drive improved patient outcome. In the first six months of 2023, we've seen a gradual recovery of overall surgical volumes and CERAMENT is rapidly capturing market shares on all markets present.Our growth rate in the first six months in constant exchange rate was 72%. Some of you have followed the company for a few years, but I must reiterate, we've only begun our journey in terms of market penetration and to deliver the full value of the CERAMENT platform. Hakan and I will take a bit of vacation now, but later in the summer we will start to plan the details and prepare for a Capital Markets Day in the autumn. One of the focuses will be on how our continued journey will look like and also how continuous new clinical discoveries goes hand-in-hand with progress on further innovation based on the CERAMENT platform. We do believe that we have quite a unique position in the market with favorable market dynamics ahead, being the only FDA-approved antibiotic-eluting bone graft in the U.S., with evidence supporting superior and sustainable clinical efficiency and health economic benefits. And on top of that, a very competent and passionate organization.So with that, I conclude this presentation and look forward to open up to a question-and-answer session.

[Operator]

[Operator Instructions] The next question comes from Erik Cassel from Danske Bank.

[Erik Cassel, analyst]

So first question, as you said, you added 10 [ VAC ] approvals during the quarter. If I remember correctly, you had 50 approvals at the end of Q1. I mean this seems like a slight deceleration compared to the VAC approvals you had during previous quarters, I mean, is that a correct conclusion to make? Or is there any good explanation for it?

[Emil Billbäck, executive]

Yeah, of course, so when we entered quarter two, as you said, we had 50 hospital system approvals. And then as we left the quarter, we had 60, so numerically slightly less approvals were added in quarter two, but that's just numerically. We have not disclosed or discussed the value of the different approvals and I would like to point your attention that in quarter two, we landed among others the Atrium Healthcare and it will go in waves also. So I think in quarter one of this year, we had an exceptional amount of approvals, but quite few of them were also on the slightly smaller side. So with the additions we had in quarter two, it's absolutely in line with our expectations and that number will go up and it will go down for various quarters. But as you can see from the sales number, we're keeping a good traction.

[Erik Cassel, analyst]

So it doesn't really imply let's call [ insuration ] Q-on-Q into Q3 then. But then you also talk of high pilot activity, is it possible to say how many pilots are running now and how that compares to end of Q1?

[Emil Billbäck, executive]

There were more pilots in quarter two than they were in quarter one. And usually from when the pilot trials are running, there is on average a three months delay before the notification comes from the VAC committee, as you mentioned before, on the approval or not approval. So given that we had a lot of pilot trials, we should start to see the hospital system approvals picking up again in the end of quarter three, beginning of quarter four.

[Erik Cassel, analyst]

And then on the sequential growth rate, quite high now compared to Q1. Is it possible for you to show how much of that is driven by more use in existing account versus added accounts?

[Emil Billbäck, executive]

No, we have decided not to go into that depth. The only -- this extraordinary effect that we decided to comment on is that we took an order from OrthoPediatrics in the quarter and OrthoPediatrics as you remember is the only of our partners that actually buy to shelf. So that order was about SEK2 million on CERAMENT G.

[Erik Cassel, analyst]

And then I also wanted to ask on the delay in the trauma application. I mean, how certain are you that you will get all the data meet this new time line? Or is there any sort of uncertainty to it?

[Emil Billbäck, executive]

Well, when dealing with huge amounts of data and very complex data, there's always uncertainties. And when dealing with FDA, there's always additional uncertainty. Why do I say that? Well, because as with CERAMENT G, we have established a completely new category with the orthopedic segment and for both Bonesupport and for FDA and I think for the industry at large, it has been surrounded with a lot of learnings on what is it that have to be in place to open up such a new category. We should remember, there are not a lot of new categories that are open in the orthopedic segments in last 10 years.We saw from our initial approval of CERAMENT G that it was a bit of trial and error also from FDA side in terms of what was demanded. So we remain confident both in the team here at Bonesupport and the partners we have, but we can never be fully sure. So if everything goes really well, well, then we will the submission in end of this year and then FDA has about 90 days for their review. But we also see several examples where FDA review the material and then comes back for supplementary information. And we have really no idea how this is going to play out. We will do our best as always, but then we will be also in the hands of FDAs, their interpretations and what it is that they would like to see for this extended indication.

[Erik Cassel, analyst]

And then one last question if I may. I mean the third generation of CERAMENT G, will that have any sort of impact on potential pricing and gross margins?

[Emil Billbäck, executive]

Hakan, you have reviewed the cost structure in detail for the new product?

[Håkan Johansson, executive]

Yes and again, Emil, as we mentioned already Q1 report, we have minor general cost increases in the manufacturing. These costs also impacts on the third generation, but that also then involved and included in the price list and the price updates that we have launched having credible effect during the remainder of the year.

[Emil Billbäck, executive]

And one can also see some of the changes that we do now, you saw in the picture is a bit of a structural change to go to a smaller package that also allows better capacity and scale. I think overtime, any such cost actually will be diluted because this also gives us the ability to keep pace with a very high market demand and economies of scale in production usually also leads to lower cost of goods eventually.

[Operator]

The next question comes from Kristofer Liljeberg from Carnegie Investment Bank.

[Kristofer Liljeberg-Svensson, analyst]

I have 3 questions. First, is it possible to update on the penetration at the approved hospitals, the figure you gave in Q1, if that has changed in any way? Also, when it comes to selling cost, you explained there were some one-off effects here in the quarter. But how should we think about them going forward? Will we see now gradually increased underlying selling cost for the remainder of the year driven by more activity and the changes you have done in the European organization. And finally, when it comes to selling commission in the U.S., if we look at that as a percentage of sales, that percentage has come down from the surprisingly high level in Q4. So I wonder if there's some seasonality in here that will be repeated this year so that selling commission as a percentage of sales will go up again in Q4 versus what we've seen so far this year?

[Emil Billbäck, executive]

Thank you very much, Kristofer, appreciate your call and your questions. So the -- we released now the report very shortly after a month closing. And we actually don't have the data available on the penetration. So we'll have to take a process on that one and come back. Currently, what we see to give you some guidance, though, is that the penetration is increasing, it's increasing significantly with those accounts where we have won contracts and we have been listed so far. And the work of the salespeople, the focus in quarter two, which will also continue very much in quarter three is actually to make sure that those contracts that we have been placed on the hospital systems that all the nurses, all the staff in the surgical theater and all the orthopedic surgeons are well trained on CERAMENT G. We know that's a good formula for sustained growth.So right now, the focus is not so much on winning new account as it is to work on the penetration, I think that should give you a little bit of hint on where the growth is coming from. When it comes to the one-offs and what to expect for the autumn, Hakan, would you like to comment on that?

[Håkan Johansson, executive]

And again, it's true that when we reported this next quarter Q2, so our selling expenses were higher also than the first quarter. But when you take the one-off in consideration they're close to SEK3 million that we impacted the latest quarter, et cetera. It is remaining quite stable to what we saw in the first quarter and this is two quarters where there has been a very high activity level in the market.We are now moving into a quarter where we will see a seasonality slowdown in those activities, but we can also expect that later in the year and in the fourth quarter, those activities to pick up again.

[Emil Billbäck, executive]

And to the final question there on selling commission, good observation. And what we -- this relates a bit back actually to your first question, it also relates back very much to our business model. So we are very picky on making sure that when we win new accounts, but we establish that account that we do the clinical validation that we do the training and that we support the surgeons to get up and running for CERAMENT in various different application.Now what does this has to do with commission? Well, it has to do with the commission because last year at the end of the year, our sales concentration was quite high, meaning that there were some of the distributors in the U.S. that were doing exceptionally well. And their commission then sprung significantly higher than the 30%, which is the average and that drove the mix of -- so that the commission looked higher.With CERAMENT G also, we have gotten on board more distributors and we're broadening the customer base and the distributor base. So the new -- also at the end of the year, the delivery of the distributors was really high. But then when we come to the new year, there are new targets again. So the -- that the commission is now closer to 30% is a natural effect of those two components.So could there be a seasonality and could quarter four again take off in commission? Well, it all depends on the sales concentration. But I would say that the sales concentration this year is less than it was last year, so that should actually give us a more stable commission around the levels that we have previously communicated.

[Operator]

The next question comes from Mattias Vadsten from SEB.

[Mattias Vadsten, analyst]

First one would be on CERAMENT G, it's the third quarter now you sell the product. So I just wanted to really hear what's deviated most from your own assessments and expectations for product thus far? And maybe try to cover sort of feedback on price in this answer as well. That would be the first one.

[Emil Billbäck, executive]

So the sales, of course, that we've seen is a bit better than we expected and the product is very well received. The -- we see both from staff in the surgical theater, as well as from surgeons that they believe the product is easy to use. And then, of course, we've done a lot of clinical studies, most of them are done in Europe. So one is anticipating that the same kind of results will be created and achieved in the U.S. But you never know, so when you launch a breakthrough product like this, it's always with a bit of uncertainty due to different therapy traditions and how they're using the product and what surgical techniques they're using.But we're very happy to say that the feedback we're getting now on those patients that have been followed up, the results are very much mirroring what we have seen in the big European studies. And that is very comforting for us, but it's also very comforting for the surgeons to see that the product performs and behaves as promised and that they can see results, which are then very similar to what has been shown in the study that gives them a confirmation that they're doing the procedure right and that they can expect also the same long-term outcome and results of the product.In terms of price and in terms of market penetration, there has been very little pushback on price. Even here, possibly slightly less than we anticipated, but it shows the dynamic of the U.S. market, where the decision-maker on the clinical achievements or let's say, the procedures to be done on the patient and the financials are usually very close to each other. While in Europe, the surgeon responsible for the well-being of the patient and the person holding the wallet are usually a bit more separated.So what does it mean? Well, it means in the U.S. that the entity making the decision on the product, the value-added committee, for example, as Erik mentioned before, they look both at the clinical efficacy, the clinical benefits and the health economic impact. And we have very strong data on the health economic impact and this is very well understood in the U.S. And that's why also price is a much smaller factor in the equation. They look more at what are the benefits mid-term, long term for us, health economic wise, but also, of course, in terms of saving legs and avoiding amputations for the patient.

[Mattias Vadsten, analyst]

And then to tweak some previous questions here a little bit. Just to understand the dynamics on CERAMENT G, in a typical hospital you are approaching now, what share of surgeons are using the product more regularly would you say? I mean, it's a difficult question, but then where you are present? Is there a lot of surgeons that are convinced or can it deviate between surge and a given hospital, so to speak. Yeah, how difficult is it to penetrate given hospital?

[Emil Billbäck, executive]

Yeah, I think this is a question we have to come back to manyx, but I'll try to give a few examples. If we compare a big hospital in Florida, in Tampa with one in Baltimore, we have hospital in Baltimore where one orthopedic surgeon started using the product and already in end of October. And what we've seen in February, March, April is that almost all the surgeons have come on board and are using the product.Then on the other hand, you go to Florida, where you have a similar size clinic. One surgeon is -- has started to use it. The other surgeons are monitoring and of course, listening to the experience on this surgeon, but need a little bit more, a little nudge, let's say, and more possibly support also from our sales and medical staff before they take the step of starting a new treatment.So it very much depends how much do the surgeons interact with each other, how much do they listen to each other and trust each other. What does the head of the department think about the product. If you look at the really, really big hospital systems, that we spoke before, we can take Atrium, for example. Atrium is a big hospital system. When we get such an approval, it doesn't really have any effect other than this gives us a hunting license. And then we have to put efforts into visit as many surgeons as we can to get them from early trial to more continuous use.And then we can take a smaller hospital system in quarter one, we won quite a few of those. Here, it's much closer between the hospital administration and the clinicians. And when a product like CERAMENT G comes on the listing, there is usually a bigger awareness and attention to such a topic. So here, it goes a little bit quicker to get more surgeons to start using the product.So there's a lot of factors that will influence how quick the penetration goes. But so far, we're very satisfied with the market penetration rate and it's even been slightly above our expectations.

[Mattias Vadsten, analyst]

The next one, I mean, I understand you build working capital, given a substantial sales growth and I appreciate the few words there, Hakan, but it looks a bit high to me at least. Anything in particular other than receivables you would want to mention here? Or we should think of?

So again, [indiscernible], if you look at the balance sheet, you see major movements only in two areas, one is inventory and that for us is important somehow way also to make sure that we have the ability to meet the growth and the volatility in growth. So it's a natural reason why we have been working actively to ensure safety stocks and levels et cetera, in raw materials to remain with a certain flexibility. And then somehow it is primarily related to the increase in trade receivables. And again, we're happy to report a strong growth and report a strong growth to customers in a business kind of business nature that represents a very low credit risk. So again, this is cash flow and payments will come, this is purely an impact of timing.

And then last one, sorry if I missed this. But did you say that you expect to hold potential CMB before the turn of the year, like during the Autumn?

[Emil Billbäck, executive]

Yes, yes, we'd plan a Capital Markets Day before the end of this year. So it's going to be sometimes during the autumn, most likely end of October or beginning of November. And here is a comment again also on the trade receivables. I think we should recognize that in the business we are in with contracts on hospital systems, the number of trade losses is incredibly low.So these are customers that even though sometimes they are a bit slow to pay, there's almost always an ability and willingness to eventually pay. So we're dealing with private hospitals and public hospitals in the U.S. It's not the same issues that the general industry saw in Southern Italy and in Greece a couple of years ago.

The next question comes from Mattias Vadsten from SEB. There are no more questions at this time. So I hand the conference back to the speakers for any closing comments.

[Emil Billbäck, executive]
