Sir, please go ahead.
Well, thank you, Catherine, and welcome, everyone, to BioVentis' 2nd quarter 2021 earnings conference call. I'm joined on the call today by Greg Anglim, our Chief Financial Officer. Let me provide you with a brief outline of what we intend to cover. I'll start by discussing our 2nd quarter revenue performance and business trends, followed by an update on our operating progress and key highlights in the quarter and in recent months. After my opening remarks, Greg will review our financial results for the Q2 2021 and our financial guidance for full year 2021, which we updated in our press release this afternoon.
And then we will open the call to take your questions. Turning to a brief review of our 2nd quarter results. We are pleased to report 2nd quarter net sales of $109,800,000 up 89% year over year, exceeding the expectations we provided on our Q1 call, which assumed growth in the range of 67% to 74% year over year. Our 2nd quarter revenue exceeded the midpoint of this guidance range by roughly $11,000,000 or 19 percentage points of growth year over year. Needless to say, we are extremely proud of the BioVentis team and the strong growth performance we delivered in the 2nd quarter.
We believe our 2nd quarter results were driven by our team's ability to build upon the momentum we saw coming out of the Q1 and importantly reflects strong organic growth overall and improving growth trends quarter over quarter. Specifically, our 2nd quarter revenue results reflect organic growth of 15% as compared to the Q2 of 2019, driven by strong organic growth versus 2019 in the U. S. Of 18%. While we are very pleased with this growth performance, we are even more encouraged by the fact that our growth trends over 2019 accelerated quarter to quarter, which reflects improvement in the overall operating environment in the period.
I would be remiss if I did not mention the other key contributor to the better than expected revenue results we reported in Q2, And that is the strong growth performance from our recent acquisition of Bioness. We are very pleased with the progress we have made in the 1st 100 days post closing, And we believe the strong execution of our integration plan helped us deliver above plan revenue contribution from Bioness in Q2. I'll share a little more color on our integration efforts later on the call, but for now, let me just say that we are proud of the early evidence that our inorganic business development strategy and execution driven plans in integrating new companies quickly and efficiently is working. Diving a little deeper into the drivers of our growth performance in Q2. For the avoidance of doubt, all growth rates referred are relative to the Q2 of 2019 in the interest of stripping out any benefit to our growth performance from an easy comparison.
Our organic growth 15% in Q2 was driven by 18% growth in the U. S, which more than offset mid single digit declines in our international sales. By global vertical, our organic sales growth versus Q2 2019 was driven primarily by 19% growth in sales of pain treatments and joint preservation products, led by 81% growth in global sales of our flagship single injection product Duralane and 59% growth in global sales of our bone graft substitute products, offset partially by a 13% decline in global sales of our restorative therapies products. As mentioned earlier, We are encouraged by the continued evidence of recovery from the pandemic that we are seeing in our global verticals, particularly in our pain treatment and joint preservation products, which posted high single digit growth over 2019 in the first quarter and 19% in Q2 and in our restorative therapies vertical, where sales trends showed modest improvement compared to Q1. The overall environment continues to improve, and we are confident in the 26% to 29% net sales growth we now expect as outlined in our updated guidance for full year 2021.
We continue to expect measured improvements in the operating environment as we move through 2021, fueled primarily by the increase in availability of vaccines and an increasing percentage of vaccinated Americans as well as Canadians and Europeans, and we continue to expect a return to normalized year over year growth trends in the Q3 of 2021. Turning to a review of our operating progress and recent highlights. First, our integration of Bioness is progressing nicely, and we are on target to have the integration largely completed by year end. By all indications, we believe the acquisition of Bioness checks many boxes as it relates to what we believe to be an ideal inorganic business development opportunity. It is a substantial commercial business serving large global and growing market opportunities with attractive growth that is accretive to our long term growth profile.
Bioness offers product solutions that align perfectly with BioVentis' existing product portfolio. We believe this acquisition will allow us to leverage our significant competitive advantage of our expansive direct sales and distribution channel, which provides us with broad and differentiated customer reach and allows us to serve physicians spanning the orthopedic continuum, including sports medicine, total joint reconstruction, Hand and upper extremities, foot and ankle, podiatric surgery, trauma, spine, neurosurgery, physiatrists and pain physicians. We also see opportunities to leverage our significant experience Commercializing high value durable medical products and expect our reimbursement team to drive improving reimbursement and order to cash performance for the Bioness business in the years to come. As we continue to execute our integration strategy in the coming months, we will be working closely with the existing Bioness Peripheral Nerve Stimulation or P&S Salesforce to expand the market penetration of STIM router through our large sales team and market access team and also prepare the market for the less invasive, fully implantable Talisman PNS device expected to be coming next year based on potential clearance in 2022. We have also started a pilot with our sales team in the restorative therapies business to introduce stim router to lower extremity clinicians that are currently prescribing ExoGen.
Bioness Neuromodulation technology is highly differentiated, patent protected and ideally suited to treat pain in the periphery. With established reimbursement coating, the stim router is the only PNS device today with an RCT and is well positioned as it is a less invasive alternative to other modalities, while also providing or avoiding the negative effects of opioid use. We look forward to sharing more updates on our integration progress in the coming months. 2 other operating highlights of note. We launched a new product in our bone graft substitutes business, and we welcomed a new member to our Board of Directors.
Building on a successful launch in Q1, limited launch, We entered full commercial launch of our Osteoamp Flowable in July. Osteoamp Flowable is an injectable allograft Bone graft substitute solution developed for a variety of patient procedures, including lumbar spine fusion, cervical spine fusion and foot and ankle fusion. We have been extremely pleased with the early market response to this differentiated product and look forward to its increasing contribution to our bone graft substitutes vertical in the years to come. Most importantly, Osteoamp Flowable, due to its injectable format, can be used in minimally invasive spinal fusions, the fastest growing area in spine. Also in July, we announced the appointment of Mary Kay Ladone to the company's Board of Directors.
Mary Kay is an accomplished executive, serving large global healthcare companies over her more than 30 year career. We are very pleased to welcome Mary Kay to our Board as she will provide valuable experience and insights as we execute our strategy of growth acceleration through new product development and M and A. Her global financial, strategic planning and business development experience as well as her strong track record of leading best in class Relations programs will be invaluable to BioVentis. Before turning the call over to Greg For a review of our financial results and updated guidance, I want to share some thoughts on 2 items of note in recent weeks. On July 29, we announced that BioVentis and Misonix entered into a definitive agreement under which BioVentis agreed to acquire Misonix in a cash and stock transaction.
Misonix Stockholders will receive aggregate consideration that values Misonix at approximately $518,000,000 on a fully diluted basis. Based on BioVentis 7 day volume weighted average stock price or VWAP of $16.6284 per share as of July 27, 2021. As outlined on our call on 29th, we see this acquisition as a strong strategic fit, Given that at BioVentis, we are a company focused on building a portfolio of clinically differentiated, minimally invasive treatments to help patients heal faster and relieve pain. Across a $13,000,000,000 addressable market opportunity, We are the number 2 player in therapy with the fastest growing single injection therapy. We are the number 1 player in minimally invasive fracture treatment and advanced rehabilitation.
We are the fastest growing participant in bone graft substitutes, and we are the technology leader in peripheral nerve stimulation. We believe the acquisition of Misonix represents a compelling opportunity to extend our leadership and expand the breadth and depth of our offerings by adding $2,000,000,000 to our addressable market. We believe the complementary nature of the two businesses will give the combined company significant diversity and scale across a range of care settings, geographies and therapeutic areas. The combined product portfolio following the closing will serve large market segments across Orthopaedics, Spine and Surgery. Together, we believe these factors will place BioVentis in a unique market position with leading technologies and specialized sales forces numbering over 500 sales reps serving a $15,000,000,000 total addressable market across the hospital, ambulatory surgical center and office care settings.
We believe the combination of our two businesses will create a differentiated growth medical technology company. And importantly, we believe it will enhance our long term growth profile to the tune of approximately 100 basis points of additional revenue growth to the combined company on a pro form a basis. We strongly believe the enhanced growth profile, combined with BioVentis' expected $20,000,000 of cost synergies, will create strong financial returns for BioVentis shareholders. We are clearly excited by the opportunities in store for the combined companies and look forward to the close, which we expect to which we continue to expect in the 4th quarter And officially welcoming the Misonix employees to BioVentis. In terms of our near term milestones for the investment community To monitor in the coming months, Misonix is planning to file their 10 ks for the 12 months ended June 30, 2021 in early September and are targeting the filing of an S-four a couple of weeks later.
We have designated a team to lead the integration and planning is already underway. We expect to be prepared to hit the ground running as soon as the transaction closes in the Q4. Finally, I want to provide a brief update on a recent clinical milestone for Agilysee, A pipeline product for BioVentis via an equity investment in a privately held company named Cartaheal. Agilis C is an off the shelf scaffold implant that is designed to regenerate hyaline cartilage and subchondral bone simultaneously. The Agilis implant has been implanted in more than 190 patients outside the United States with follow-up of more than 4 years and is CE marked.
The product was granted breakthrough device by the FDA last year and recently announced high level results from a 2 year randomized and controlled pivotal IDE study. The study's objective was to demonstrate the superiority of the Agelis implant over the surgical standard of care, microfracture and debridement for the treatment of cartilage or osteochondral defects in both osteoarthritic knees and knees without degenerative changes. We estimate this to be a 1 point $3,000,000,000 market opportunity. This is a noteworthy clinical milestone given our equity purchase agreement with Cartagile. As disclosed in our SEC filings, the agreement provides us with an exclusive option to acquire 100% of Cartagena's shares upon pivotal clinical trial success, including achievement of certain secondary endpoints and FDA approval of the Agilisys device with a label consistent in all respects with pivotal clinical trial success.
Consideration for the acquisition of all of the shares of Cartagile would be $350,000,000 with an additional $150,000,000 payable upon achievement of certain sales milestones related to Agilisys. On August 2, 2021, Cartagheal provided us a statistical report containing the results of the pivotal clinical trial. We are currently reviewing the report to assess if it is consistent with the terms of the agreement. We have the right to terminate our option agreement at any time ending 30 days after receipt of the statistical report from Cartagile upon payment of a breakup fee of $30,000,000 If we decide to move forward with Cartagile, we will be required to put $50,000,000 into escrow as a deposit towards the $315,000,000 of consideration owed following the receipt of PMA approval. We are not able to discuss the clinical study results or the statistical report at this time, but we intend to announce our decision regarding the equity agreement via a press release.
Some notes to bear in mind regarding our Cartagel relationship. Number 1, If we decide to move forward with Cartagile, we have an option to acquire the company, but not until Agilisys receives PMA approval. Number 2, Cartagena submitted the PMA non clinical module and the manufacturing module to the FDA earlier this year and continues to expect the submission of the final clinical module in Q4 of 2021. Number 3, our expectation regarding the potential timing of any acquisition of Cartagel has not changed. We continue to expect the earliest a post PMA approval acquisition would come is mid-twenty 22.
And number 4, we believe we have the requisite capital to execute our strategic growth initiatives for the existing BioVentis business, to finance our transaction with Misonix and to continue to invest in our product pipeline, including Agilisys. With that, let me turn the call over to Greg for a detailed review of our financial results in the Q2 of 2021, as well as a review of our updated 2021 financial guidance.
Thank you, Ken. For the avoidance of doubt and unless otherwise noted, my commentary will focus on the company's non GAAP results for the 2nd quarters of 2021 2020. We have included definitions and full reconciliations from our GAAP reported results to the related non GAAP item in our press release this afternoon. Turning to a review of our Q2 financial results. GAAP net sales increased $51,800,000 were 89% year over year on a reported basis and increased 88% on a constant currency basis.
Gross profit increased $38,000,000 or 84% year over year and represented 76.5 percent of sales compared to 78.7% of sales in the prior year period. The year over year change in gross margin was driven primarily by the mix of revenue by geography and by vertical as compared to the prior year period. Note, our gross profit excludes non cash amortization expense of $5,600,000 for the Q2 of 2021 compared to $5,300,000 last year. 2nd quarter of 2021 gross profit also excludes $2,100,000 of inventory step up costs related to our acquisition of Bioness. Total operating expense increased $31,300,000 were 79% year over year to $70,800,000 The change in total operating expense by line item was driven by a $29,000,000 increase or 79% year over year in SG and A expense and to a lesser extent a $2,200,000 or 86% year over year in R and D expense.
The increase in operating expense compared to the prior year period was primarily driven by investments in our selling and marketing organization, public company costs, which did not impact the prior year period results and the resumption of discretionary spending, including travel and related expenses given the more normalized business environment as compared to the significant cost reduction efforts in the prior year period as a result of the COVID-nineteen pandemic as well as operating expenses related to our acquisition of Bioness, which did not impact the prior year period. As detailed in the non GAAP reconciliation tables in our press release this afternoon, We exclude non cash amortization, acquisition costs and expenses and other non recurring costs from our non GAAP operating expense. 2nd quarter operating expense also excludes 2 non cash items that did not impact prior year period reported results. Specifically, a $600,000 of non cash expense related to the change in fair value of contingent consideration and $5,700,000 of non cash charges related to impairment of assets related to Harbor, of which $5,200,000 was attributable to non controlling interests. Operating income was $13,300,000 compared to operating income of $6,200,000 for the Q2 of 2020, an increase of $7,100,000 or 113% year over year.
Operating margin was 12.1 percent of net sales compared to 10.7% of net sales in the prior year period. In summary, our performance across the P and L in Q2 resulted in non GAAP net income of $9,600,000 up 168% year over year and adjusted EBITDA of $19,900,000 up 186% year over year. As detailed in the non GAAP reconciliation table in our press release, adjusted EBITDA excludes the impact of stock compensation expense and other non cash or non recurring items. We believe this provides supplemental information about the underlying operating performance of our business. Turning to the balance sheet.
As of July 3, 2021, the company had $136,100,000 in cash and cash equivalents and $181,100,000 in debt obligations compared to $86,800,000 in cash and cash equivalents and $188,400,000 in debt obligations as of December 31, 2020. As of July 3, 2021, we had approximately $50,000,000 of available borrowing capacity on our revolving credit facility. Turning to a review of our fiscal year 2021 financial guidance, which we updated in our press release this afternoon. For the avoidance of doubt, our updated 2021 financial guidance includes the contributions from our acquisition of Bioness following the closing date of March 30, 2021, but does not include contributions from the proposed acquisition of Misonix, which was announced on July 29, as it is yet to close. The company expects to update its 2021 financial guidance to include contributions from Misonix following the closing, which is expected in the Q4 of 2021.
For the 12 months ending December 31, 2021, The company is reaffirming the updated revenue guidance provided in our preliminary second quarter revenue results press release on July 29, which called for net sales of $405,000,000 to $415,000,000 up approximately 26% to 29% year over year. The increase in our net sales guidance range is driven by the stronger than expected sales results in the Q2 of 2021. The updated net sales guidance range assumes net sales from legacy BioVentis Inc. Of $372,500,000 to $380,500,000 representing organic revenue growth in the range of approximately 16% to 18% year over year and net sales from the acquisition of Bioness Inc. Of approximately $32,500,000 to $34,500,000 With respect to our profitability guidance, We now expect GAAP net income of $13,000,000 to $17,600,000 of which legacy BioMentis is expected to contribute GAAP net income of $29,200,000 to $33,300,000 with Bioness contributing the remaining balance.
We now expect non GAAP net income of $67,100,000 to $69,500,000 of which legacy BioVentis is expected to contribute non GAAP net income of $75,600,000 to $76,600,000 with BioVest contributing the remaining balance. We now expect adjusted EBITDA of $77,800,000 to $82,000,000 of which legacy BioNTech is expected to contribute adjusted EBITDA of $82,800,000 to $86,100,000 with Vioness contributing the remaining balance. In addition to the formal financial guidance provided in this afternoon's release, we would like to provide some key assumptions to bear in mind when evaluating our growth expectations for 2021. First, our full year 2021 net sales guidance range assumes the following for net sales by geography. U.
S. Net sales growth in the range of 23% to 26% year over year and international net sales growth is expected to be in the range of 55% to 60% year over year. These ranges assume U. S. Sales growth on an organic basis in the range of 15% to 18% year over year and contributions from our acquisition of Bioness and international sales growth on an organic basis in the range of 22% to 24% year over year, as well as contributions from our acquisition of Bioness.
For net sales by vertical, our full year 2021 guidance now assumes Low to mid-20s percent growth in global sales of pain treatments and joint preservation products, driven by low 20 percent organic growth and contributions from Bioness, lowtomid30s percent growth in global restorative therapies growth driven by low single digit organic growth and contributions from Bioness and high 20s to low 30s percent growth in global sales of BGS products. 2nd, we continue to expect to see measured improvements in the operating environment as we move through 2021, fueled by the increasing availability of vaccines and an increasing percentage of vaccinated Americans, Canadians and Europeans. Our full year 2021 guidance continues to assume a return to normalized year over year growth trends in the Q3 of 2021. Finally, with respect to our expectations for financial performance in 2021, we would like to provide some of our assumptions to help evaluate our full year 2021 guidance for GAAP and non GAAP net income. For the full year 2021 period, we expect non GAAP gross margins of approximately 77.6% to 78.1%.
GAAP operating expense growth of 23% to 26% year over year, driven primarily by the incremental operating expenses related to our acquisition of BioNess, Low double digit growth in legacy BioVentis operating expenses compared to 2020. Note, the increase in GAAP operating growth range versus prior guidance is driven by the non cash impairment charges and non cash expenses from contingent consideration in the Q2 of 2021. We also expect interest expense net of approximately $2,300,000 Total non cash depreciation and amortization of approximately $31,000,000 to $32,000,000 Non cash stock comp income of approximately $2,700,000 to $3,700,000 and weighted average diluted Class A shares of approximately 42,000,000. With that, I'll turn the call back to you, Ken.
Thanks, Greg. Before opening the call for Q and A, I want to summarize the main points of the Bio Aventis investment story, which I believe will illustrate why we are so enthusiastic about the long term outlook for the company. Number 1, we are a company focused on building a portfolio of clinically differentiated minimally invasive treatments to help patients heal faster and relieve pain. We are confident in our multi year organic growth profile, which is increasingly compelling and fueled by our market penetration strategy in both our pain treatment and joint preservation and bone graft substitutes verticals and expanding our reach in our restorative therapies vertical. Number 2, our product pipeline is robust and is expected to fuel accretive growth in the medium term with potential products like Agilisie by CartiHeal, Motus, ProCuff and Talisman, The implantable, less invasive PNS device from Bioness.
Number 3, our M and A strategy is designed to bring in positions that are expected to bring an accretive growth to our global business and leverage our strong commercial infrastructure to bring about consistent double digit growth. As discussed, our acquisition of Bioness in March and our recently announced pending acquisition of Misonix represents ideal fits in terms of how our M and A strategy will enhance our long term growth profile and create further value for our shareholders. Importantly, we will continue to be measured and prudent and our approach to M and A as we have with both the Bioness and Misonix deals. Number 4, Operationally, we are focused on continuous improvement to positively impact our margins, including cost savings initiatives from And supply chain perspective, while also enhancing our quality programs to meet ongoing changes in our regulatory environment. And number 5, and most importantly, our strategy is backed by a highly engaged results driven culture that is fueled by an employee driven mission to improve the lives of the thousands of patients that are treated each day by one of our medical devices, returning them to active lives.
With that, we will open the call to take your questions. Catherine?
Thank you, We do ask that you limit yourself to one question and one follow-up. If you would like to ask additional questions, We invite you to add yourself to the queue again by pressing star 1. We will now take a moment to allow participants to join the queue. And answer our first question from Ruby Marcus of JPMorgan. Please ask your question.
Great. Thanks for taking the question. Maybe we could start on the outlook. I think people are Getting very concerned about the impact of COVID and the Delta variant, particularly in the Southeast, with some hospitals in Texas and Florida and other states starting to put off elective procedures. It doesn't sound like the guidance Sarah Lee assumes a worsening of the situation.
So it'd be great to get your take of what you're seeing right now in the U. S, particularly in the Southeast? And are you seeing an impact so far in Q3 from the rising cases? Thanks.
Yes. Thanks, Robbie, good to hear your voice and thanks for your question. It is a concern and one that we're watching carefully. At this point in time, it is not impacting our business, keeping in mind that BioVentis is broadly diversified Geographically across the United States, where we sell in a given month to thousands of surgeons across our 3 verticals. That really helps us, where we may have some regional spikes, which is I think what we're seeing with the Delta variant, Where there's some impact in elective procedures, but we're broad enough based at this point, where we have not seen an impact.
We're obviously continue to watch that carefully, but our guidance assumes we've returned back to normalized growth In the second half of this year.
Got it. Okay. So it doesn't seem like It's really impacting you from Q2 trends at all in a material way yet?
No, it's not, Robbie, and hopefully, that will continue for us.
I hope so too. Maybe a quick follow-up, more of a strategic question. With a couple of deals announced in Cartesi or Cartagile, and that was planned from the time of the S-one. So it shouldn't be much of a surprise, but how are you thinking about further M and A from here and particularly your ability to finance further M and A. Would love to get your thoughts.
Appreciate it.
Yes. Thanks, Robbie. Our M and A strategy, as we've talked about since we went public earlier this year, Is not to drive growth for growth sake with M and A, but really look at it from a strategic perspective and make sure it marries and leverages our commercial channel. We've been fortunate to find 2 in Bioness and the pending acquisition with Misonix. We will continue to look at other M and A, and we'll take a prudent and measured approach That those potential deals, if we go that far, are ones that will return value to all shareholders, And that will be a key measurement device.
We have assessed carefully where we stand relative to Misonix and completing that acquisition, which we expect to close in the Q4. And then CAR2Heal, and as highlighted on the call, we don't expect Cartagheal, if we do move forward to receive PMA approval until mid-twenty 22, which puts Quite a bit of daylight between the close of Misonix and the Cartagile deal. So we are in a strong position With low debt, not leveraged, but very strong cash that drives down to our bottom line every month. So we'll continue to certainly look at our M and A pipeline and look at opportunities that drive accretive growth. But as we've done in the past, it will be a measured and prudent approach.
And we just have, in our case, Some very good synergies that we've been able to take advantage of here in the near term with both Bioness and Misonix, and we're clearly excited about Cartagheal, And we'll be assessing that technology and as mentioned are in process of doing that right now.
Great. Maybe if I could sneak in one more. Now that you've had some time to digest the acquisition, At least since the announcement a couple of weeks ago, any updated thoughts on accretion for the 1st year and the 2nd year on adjusted EBITDA and how that impacts net income? Thanks.
Yes, Ravi, it's Greg. I'll take that one. With respect to Misonix, I don't think there's any Updated thoughts at all. As we said at the time of that announcement, we expect that acquisition to be accretive to our adjusted EBITDA in the first full year after the completion of the transaction and accretive to our adjusted EBITDA margins by the 2nd full year after completion. And really no change to that from what we said at that point.
Thanks.
And sir, our next question from Amit Hazan of Goldman Sachs. Please ask your questions.
Hey, this is Phil on for me. Can you guys hear me okay?
We can, Phil.
Awesome. I wanted to circle back to Delta in maybe a slightly different way than Robbie asked it and asked about patient risk aversion, kind of independently of constraints on facilities in the hospital. So I'm wondering what your learnings were on patient risk aversion Over the last roughly year, 18 months and how you're thinking about that moving forward and any differences that you see in different divisions? Obviously, there's slightly different dynamics between the different segments that you guys operate under?
Yes. It's a great Question, Phil, and let me try to answer it by the verticals. And a lot of our data will be U. S.-based, but certainly, we I'll reflect on some international Points as well. First of all, on our therapy, in our pain treatments area and that vertical, We saw last year reticence to go into physician offices, keeping in mind that, that Particular population with is elderly people or people over the age of 65 and sometimes quite a bit older.
We've seen a return, a full return to our business as the vaccines have become available late last year early this year. And as you can see from our results, we continue to see continued strong growth in that area And continue to gain market share in the space in general. ExoGen is more of a broad based technology in our restorative therapies area. And that particular area, it's it was impacted throughout 2020 because The reduced activity level, reduced trauma, and then we've seen a consistent pickup across the back half of twenty twenty And into 2021. I don't expect that to be impacted, because that's more trauma related and as long as People will continue to remain active and we don't have shutdowns.
The impact of a delta variant will not be extensive on on that restorative therapies area or exogen. And for that matter, on the advanced rehabilitation area with Bioness, I would say the same thing, where it's more stroke and focused at this point. And in areas like that, that affect Gates, We don't expect a significant impact there unless there would be some type of significant shutdown. And then we're going to our bone graft substitutes area, that also, is more We have a younger patient group in spinal fusion that can vary in age from 50 to 70 typically. And we have not seen a decline in elective procedures.
As I mentioned, Phil, there is some regional pressure on occasion, Depending on the area, where there might be spikes, but we're broad enough based with that business that we have been fortunate we have not Seeing any real impact to our growth profile. And on peripheral nerve stimulation with stim router, It's really the same thing. That's right now focused where our focus is on post surgical pain And some chronic and lower extremity pain, and we have not seen any impact there. And again, we'd have to see a significant shutdown to see PMS impacted. Now where we have seen an impact with the pandemic has been more internationally where we are direct in the UK And Canada and Germany, we have seen a much more of a significant impact as you can see from our numbers.
They are rebounding though, and we expect in the second half of the year with continued vaccination growth that patients will return to normal treatments in those markets as well as our distributor markets outside of those 3 direct markets, and we continue to stay positive on that mentality.
One more, if I may. The Exigent system, I think growth, if you look on a kind of a compound basis, Slowed sequentially versus 1Q. I'm wondering what happened in the market there. Obviously, we have some things going on in 1Q that I think could have actually slowed Growth on that side. So what happened in 2Q?
And what gives you confidence in the reacceleration that's implied in guidance for that business? Thanks.
Yes. Thanks, Phil. Well, just to be clear, we did see sequential growth in ExoGen from Q1 to Q2, and we're very pleased with that. So from our perspective, ExoGen, we continue to expect low to mid single digit growth with the product. And we continue to be strongly optimistic on ExoGen to deliver from a profitability perspective.
So as far as we're concerned, we've continued to see really good numbers there and encouraging numbers. As I mentioned, we did ExoGen was hit last year, particularly with the reduction in trauma, but we've seen that pick up and we've seen Good sequential growth from Q1 to Q2 now.
All right. Thanks. I'll leave it there and come back in queue.
Thanks, Phil.
And our next question from Drew Ranieri of Morgan Stanley. You may ask your question.
Hi, everyone. Thanks for asking the question or taking the question. Just Going back to the Q3 for a moment, just your comments that you're expecting a return to normalized year over year growth trends in the Q3. It looks like consensus has about $102,000,000 for the Q3. But if I kind of look back at maybe what your normalized growth rates would have been, It seems like we might be coming out to like $95,000,000 to $98,000,000 Just curious if you're comfortable where consensus currently stands just kind of given the trends That you're seeing in the business
and variance? Yes, Drew, thanks. It's Greg. And Short plan version is, we've said all year long, we expect to get back to normalized growth in the second half. We continue to say that.
If you go back and you look at our business historically, Q2 to Q3, our business stays relatively constant. Maybe, Dibs, just a hair, but our business certainly builds from the Q1 to the Q4, but is relatively constant from Q2 to Q3. So we remain very positive in terms of our outlook for the rest of the year.
Okay. And then I'll put these two questions together. But Can you maybe talk a little bit more about the pilot program between for stem router and exogen? And then second, just Give us a pipeline update for bones and Motive. Thank you.
Sure, Drew. Well, first of all, the pilot program was something we launched several months ago with our sales team that sells ExoGen and specifically calls on lower extremity surgeons, foot and ankle orthopedic surgeons and podiatric Surgeons where there's a real need for peripheral nerve stimulation depending on the procedure and the area that they're treating. As we brought the team in, it was 25 of our sales reps, so a small percent. That's gone quite well As they've gone out in the field, they've been trained working closely with the Bioness peripheral nerve stimulation sales force. So we're very excited about that opportunity.
It's an initial focus for us just to gain market experience And have our reps gain experience and confidence with the STIM router product. From our perspective, we look forward to a full launch across our broader sales force in this area going into 2022 and obviously also the next generation Talisman product, which we also expect 510 clearance on and availability with that in 2022 as well. As far as bones, there's not a lot to update on at this point. As highlighted before, we have a deficiency letter from the FDA on the metatarsal study and we are in discussions with FDA and Expect to continue to work to resolve the deficiency letter. And once again, this is a PMA supplement that does take some time as the team works through that.
So we'll have updates as we get them that are material in that area. And then on MODIS, we continue to work through our Phase 1 study. It's now 2 sites in the U. S. And we're ready to commence our Phase 3 study on schedule in the 3rd quarter or Phase 2 study rather on schedule in the 3rd quarter.
So very excited about what that product represents and the strong adjacency that we see in our portfolio with MODIS As a placental tissue product that can have disease modifying implications as well as reduce inflammation in the knee joint. So that continues to really progress nicely and our team has done a terrific job moving that forward via the BLA application process.
Thanks for taking
the questions.
Thanks,
from Kyle Rose of Canaccord. Please ask your question.
Great. Thank you very much for taking the questions. So I wondered if we could just ask more of a bigger picture M and A question. I understand that your appetite for continued M and A, it remains strong. When I look at the 2 deals that you've done, or one pending and one closed one, I mean, they're a bit more tangential than I think maybe we would have expected, broadening into the wound care market as well as More on the operative side of the spine market and then when I look at Bioness, you've got Multiple different market segments that you're broadening to.
Do you expect to continue to move into additional adjacent market segments or More so than invest in the existing markets that you're in now?
Yes, it's a good question, Kyle. And really when you look At the segments that we're in, in the verticals, these were highly adjacent areas, which is why we did them and they leveraged our commercial channel and the infrastructure that the Structure that the company has. I mean, if you start with Bioness, we're using our current sales force. Obviously, it's just a pilot right now, but we will to continue to penetrate the peripheral nerve stimulation market, which is a significant one when you look at the opioid crisis And the use of opioids post surgery. These are all physicians and surgeons that we call on daily.
So leveraging that has been critical. And then obviously on the Advanced Rehabilitation business, There is an operational synergy as well as a commercial synergy operationally with the durable medical equipment and that process We have well honed with ExoGen and then commercially expanding their gait restoration products to use in osteoarthritis and our sales force also going in that direction where we see a lot of great synergy. And then with Misonix, it is essentially the same strategy going deeper with what we have. Starting with spine, The unique strategy that we have being agnostic to spine hardware and leveraging our bone graft It's across a broad portfolio of opportunities in hospitals and surgeons. Misonix has taken the same strategy with the BoneScalpel And we view that as a definite 2 plus 2 equals 5 because that strategy and this relatively small market penetration we both have will allow acceleration of growth using our combined commercial channels.
And certainly on the wound area, That's a direct synergy with our ExoGen Call Point. There's about 4,000 physicians today that we that prescribe ExoGen annually that treat wounds in the office. The wound market has shifted with the pandemic to more office based treatments. Some of that's based on patient comfort, not wanting to go to the wound center and that's our strong suit. So we see direct synergy there in combination with the Misonix wound sales force, which largely focuses in the wound centers and the hospitals.
So I like to call our business, Kyle, when we started out a mile wide and an inch deep, And all we're doing is taking that inch deep and we're going 2 or 3 inches by going deeper with our customers. It might seem like it's not tangential, but when you really look at it and hopefully that makes sense the way I described it, we are going deeper with the same customers using our same commercial channels. So we're very excited about that. We'll continue to take a measured and prudent approach and a careful approach in M and A. We've just been very fortunate that we found 2 really good ones here of light that are great fits for BioVentis and our ability to drive long term accretive growth, which both acquisitions we feel will do for our shareholders.
Great. And then just
last question for me is, it sounds like the CARTAHEAL data looks pretty good, at least from a top line perspective. Understand all the timelines. So just trying to understand maybe from your side, what would prevent you from moving forward with the deal as is already structured? Thank you.
Thanks, Kyle. Look, we're there's not a lot I can comment on. As I said, we're viewing the data now. We'll look at the data and the market opportunity carefully. We are excited.
It's a great technology. It's a great product. We just have to look at this holistically. And that's what we're in the process of doing. We will announce our decision via press release here.
And From our perspective, that's about all we can say at this point in time. So we'll keep everyone posted on next steps there.
And sir, we are currently showing no additional participants in the queue. That does conclude our conference call for today. Thank you all for participating. You may now disconnect.
