  • Laura Francis - Chief Executive Officer

  • Thanks, Saqib. Good afternoon, and thank you for joining us. I'm pleased with our team's execution, as we delivered another strong quarter and set new records across several key metrics.

  • In the second quarter, we delivered a record $40 million in worldwide revenue, representing 20% growth. US revenue was a record $37.8 million, representing 21% growth, as we benefited from strengthening demand for our growing number of solutions. We added 220 active physicians in the quarter compared to the prior year, hit another new record for active physicians, and completed record-breaking number of new physician trains in the quarter.

  • Our second-quarter results are indicative of the company's transformation from a single-product company to a unique, high-growth medical device platform. We have a proven track record of identifying and successfully developing new markets, with large unmet clinical needs across sacropelvic conditions. Complementary markets in pelvic fixation and trauma have doubled our total target procedure volume to approximately 0.5 million annual procedures, driven deeper physician penetration and allowed us to deliver 20%-plus average revenue growth over the last three years.

  • We also made dramatic progress on our profitability goals in the quarter as we delivered a 43% improvement in our adjusted EBITDA. Over the last three years, we've achieved over 30 percentage points of improvement in adjusted EBITDA margin. We continue to achieve significant operating leverage in the business driven by our strong revenue growth, increasing use of our hybrid commercial model, and scalable corporate infrastructure.

  • Given the durability of the tailwinds in our business, we expect revenue growth to accelerate in the second half, driven by the continued physician growth across all our markets, procedure volume growth across surgeons and interventional spine for SI joint dysfunction, and acceleration in demand for our pelvic fixation solutions. We expect this top line growth to translate to positive adjusted EBITDA in the fourth quarter of 2024. This inflection in our adjusted EBITDA profitability combined with our solid liquidity as well as our capital efficient model will give us the flexibility to self-fund our future growth. We're also positioned to capture the large numerous markets in the sacropelvic space and deliver sustainable and profitable revenue growth going forward.

  • Now, let me provide an update on our key initiatives as we look to extend our leadership, drive long-term growth, and create shareholder value. Starting with sales infrastructure. We ended the quarter with 84 territory managers, supported by clinical support specialists and third-party agents for case coverage. Our hybrid commercial strategy drove a 24% increase in our trailing 12 months revenue per territory to a record $1.7 million. Our differentiated portfolio is attracting the attention of multiple large regional distributors, who have expressed interest in building agency partnerships.

  • We continue to expand our agent network, primarily for public fixation and trauma opportunities. The expansion of our agent network is allowing us to reach more physicians and also drive incremental operating leverage in the business. Concurrently, we plan to selectively and strategically hire additional territory managers to ensure that we can expand our physician users and density as well as provide the highest quality of service through our growing user base.

  • Moving on to physician engagement. We exited the quarter with more than 1,150 active physicians, representing 23% growth. This is a continuation of the double-digit growth in active users we've seen in the last three years. In the second quarter, 17% of our active physicians use more than one of the procedural solutions we offer. The 25% increase in the number of active physicians performing more than one type of procedure, highlights the synergistic nature of our portfolio.

  • With the launch of Granite 9.5 solution, we're targeting both deformity and increasingly degenerative spine procedures, which account for a significant portion of the procedure volumes for our active physicians. We now have a platform to drive deeper engagement and more procedures per physician. This cross-portfolio interest is a positive leading indicator of sustained demand momentum and productivity.

  • Moving to our academic program. We trained 80 residents and follows in the second quarter, bringing the total number of trained residents and fellows to over 1,700 since 2018. This effort translates into a growing number of physicians trained who now understand the incidence and diagnosis of sacropelvic disorders and treatment options using our technologies. We're encouraged by the elevated interest in training and the adoption trends by previously trained residents have followed.

  • In the first half of 2024, sustained adoption from previously trained residents and follows, resulted in revenue attributable to this group growing 75%. Turning to products and clinical evidence. We continue to define the SI joint dysfunction public fixation in pelvic trauma markets and reinforce our commitment to improving patient outcomes and advancing medical care by offering differentiated products backed by clinical evidence.

  • We recently finalized five-year follow-up data for SALLY, our first prospective clinical trial with iFuse-3D. The study indicated that the clinical response to SI joint fusion using iFuse-3D showed market immediate and sustained improvement in all outcome measures, consistent with our prior SI joint fusion studies. The patient pain score improved by 58 points. The disability scores improved by 25 points, while the percentage of people on opioids decreased from 57% at baseline, to 17% at five years.

  • The physical function test showed persistent improvement from baseline and the long-term radiographic analysis was positive with 100% rate of joint fusion. Our physicians have migrated from the original iFuse to iFuse-3D due to porosity and fenestrated design, driving faster and better fixation and fusion. iFuse-3D accounts for almost the entirety of our triangular titanium implant revenue and is patented through 2035.

  • iFuse-TORQ building on the success of iFuse-3D continues to be a key contributor to procedure volume growth and active physician engagement across both SI joint dysfunction and pelvic trauma and has been a cornerstone of our Interventional Spine engagement strategy. While we provide comprehensive training on both iFuse-INTRA and iFuse-TORQ, in the second quarter, the majority of the cases performed by interventionalists utilized iFuse-TORQ in a lateral transfixing trajectory, which is reimbursed under CP2 Code 27279.

  • The growing confidence of interventionalists and adopting iFuse-TORQ aligns with the early outcomes we're seeing in our prospective multi-center interventional STACI study. Interim results, which were recently presented at the American Society of Pain and Neuroscience Annual Meeting in Miami, confirm the safety efficacy of lateral transfixing SI joint fusion when performed by interventionalists.

  • The safety and effectiveness of the lateral procedure with iFuse-TORQ was also confirmed in a recent publication in the Journal of Pain Research by Dr. Michael Jung, a leading interventional spine position at Wisconsin Spine and Pain. Dr. Jung published the results from his first 49 lateral SI joint fusion cases using iFuse-TORQ. The outcomes were commensurate with those observed in a large meta-analysis of studies of lateral SI joint fusion published last year. And an average of six months of follow-up, 88% of patients reported at least 50% improvement in pain.

  • Since its launch in 2022, iFuse Bedrock Granite has been highlighted as one of the most innovative products by our customers and has seen rapid and durable adoption. Even with the rapidly increasing demand, we still have a large underpenetrated opportunity. We believe that Granite will become the standard of care for fixation infusion of the SI joint to provide a strong foundation at the base of long construct procedures addressing a clear unmet clinical need in spine surgery.

  • Granite has also found significant application in shorter, 2 to 4 level lumbar fusion procedures. In the second quarter, we launched Granite 9.5 to address the specific needs of this broader category of lumbar fusion procedures. We believe that Granite 9.5, including shorter length appropriate replacement in the S1 pedicle, will provide the best-in-class offering for approximately 100,000 annual target procedures. It will also allow us to engage deformity surgeons who have expressed an additional preference for a smaller diameter implant to better enable 2 points of pelvic fixation. The reception for Granite 9.5 has been spectacular.

  • Looking ahead, we have an active pipeline of differentiated products that will be launched in the coming months and years, beginning with the fourth quarter launch of a product specifically targeting the pelvic channel market. Before Anshul discusses our financial performance, let me provide a quick update on the recent additions to our Board of Directors.

  • On June 25, our shareholders elected Thomas West to our Board of Directors at our Annual Stockholder Meeting. Tom is the CEO of Nalu Medical, a privately held medical device company with a lead physician in peripheral nerve stimulation, selling primarily to interventional pain physicians. Tom built his career Johnson & Johnson and Hologic and was recently CEO of Intersect ENT, up to its acquisition by Medtronic.

  • Today, we also announced the appointment of Dan Wolf to our Board. Dan is currently the Senior Vice President and Chief Strategy and M&A Officer at Baxter International. Previously, Dan held positions of increasing responsibility at Medtronic, including business development and operational leadership of Medtronic's push in the personalized spine surgery with the acquisition and management of Medicrea.

  • Tom and Dan bring a great mix of operational and strategic medical device experience across spine surgery and interventional pain, and are tremendous additions to our Board of Directors.

  • With that, I'll hand the call over to Anshul.

  • Anshul Maheshwari - Chief Financial Officer

  • Thanks, Laura. Good afternoon, everyone. My comments will be focused on second-quarter growth, profitability trends, and liquidity. Starting with revenue growth. Our second quarter's worldwide revenue was approximately $40 million, representing growth of 20%.

  • US revenue grew 21% to $37.8 million due to strong US procedure volumes and the continuation of the favorable ASP trends we have seen for the last several quarters. We have now delivered more than 20% US revenue growth in 9 out of the last 10 quarters. The consistency of this revenue growth is an outcome of our strategy to work with a sizable physician base, to create new market categories, and diversify our revenue streams.

  • International revenue in the quarter was $2.2 million.

  • Moving to gross margin and operating leverage. Our gross margin for the quarter was 79%, our gross margin was impacted by procedure and product mix. These were partially offset by the benefit from our ongoing effort to streamline our supply chain to lower our implant costs.

  • Operating expenses were $41.7 million, representing approximately 7% growth. The increase was due to higher commissions driven by revenue growth, increase in commercial activity to support new product launches, research and development investments, and increase in stock-based compensation.

  • Looking at the first half of 2024, we are proud of the more than 2x operating leverage in the business. Our net loss improved by 20% to $8.9 million, or $0.22 per diluted share.

  • Our adjusted EBITDA loss was the lowest since the IPO at $2.7 million, reflecting a 43% improvement. Compared to the first quarter of 2024, our adjusted EBITDA improved 33%.

  • Turning to liquidity. We exited the quarter with a robust balance sheet, including $151 million in cash and marketable securities. Our cash usage in the quarter was $6.5 million as we invested in Granite 9.5 inventory, as well as surgical capacity to support the anticipated second half demand.

  • Finally, moving to our updated outlook for 2024. Based on our second-quarter results, we are increasing our 2024 worldwide revenue guidance. We now expect 2024 worldwide revenue of between $165 million and $167 million, implying year-over-year growth of approximately 19% to 20%. Considering the 2x operating leverage for the full-year 2024, we expect to achieve adjusted EBITDA breakeven in the fourth quarter.

  • With that, I will turn the call over to Laura.

  • Laura Francis - Chief Executive Officer

  • Thanks, Anshul. We're seeing robust demand for our differentiated solutions, as well as record physician engagement. That, combined with our efficient execution, will allow us to deliver industry-leading and profitable growth going forward. I'd like to thank our world-class team for their efforts to help build a sustainable high-growth medical device platform that has helped over 100,000 patients.

  • With that, we're happy to take your questions. Operator?

  • Operator

  • (Operator Instructions) Matthew O'Brien, Piper Sandler.

  • Matthew O'Brien - Analyst

  • Well, afternoon. Thanks so much for taking the questions. Maybe for starters, Laura, just the dock utilization in the quarter and I know that number has been rising nicely. But just on a seasonally adjusted basis, it was softer in Q2 of this year than we saw in Q2 of last year.

  • So I'm just wondering what kind of dynamics are going on that are impacting it? I don't know if it's the shift to more interventionalists or something along those lines. But just can you talk a little bit about why that's a little bit softer than we saw this time last year. And then I do have a follow-up.

  • Laura Francis - Chief Executive Officer

  • Thanks for the question. And maybe just kind of a general summary, we really are thrilled with yet another strong quarter, delivering record performance across all of our KPIs. So 21% US revenue growth, and that was led by strong demand across all of our target markets; 25% increase in the number of physicians doing more than one procedure type; 23% growth in our active physician base.

  • We did talk generally about a record number of new physician trainings given the elevated interest in a number of different parts of our portfolio. And then we're quite proud of the improvements in productivity as well.

  • So in terms of a softer number, I actually think that we're showing a very strong quarter here. So over the last three years, we consistently have seen double-digit growth every quarter in our active physicians. We typically do look at year over year, given that there can be some seasonality in these numbers. But we ended the second quarter with 1,150 active physicians, so once again, 23% growth.

  • And if you look year over year, it was 220 additional users. So it's the second consecutive quarter where we had a record number of new physicians trained, which is a good forward-looking indicator for future active physician growth. And just given the expanded portfolio, as well as our world-class medical affairs team that's focused on training physicians on multiple modalities. I feel great about our ability to increase the number of active physicians in the second half, and also to increase cases per physician.

  • Matthew O'Brien - Analyst

  • Got it. And then I don't know if this is a question for you or for Anshul, but when I look at the first half of the year, the performance is really good in the US, but it does -- the guidance and sticking with just the raising by the amount of the beat here in Q2, does imply a pretty sharp two-year stack deceleration in the back half of the year and that comes with 9.5 addressing a lot more patients. I'm just wondering, help me reconcile why we would say this deceleration in the US versus what we've been seeing with all these new stocks, reps and then products as well.

  • Anshul Maheshwari - Chief Financial Officer

  • Yeah. So Matt, I can take that question. So we don't think about the business in stack growth. I don't think it's the right way to think about the business that way, because there's various number of factors that can impact the starting point. You're right. When we -- as part of our guidance at $165 million to $167 million is actually an acceleration in the second half of 2024. And that, even when you look at the third quarter, our expectations is, generally, the third quarter sees a sequential decline of 2% to 3%, and we expect to offset that with the tailwinds.

  • Laura has talked about the rollout of Granite 9.5 as well. And in general, our guidance philosophy is always being thoughtful. We've now had a consistent track record of exceeding expectations, but I just want to be thoughtful going into the second half. We've got a lot of good KPIs, including a record number of active physicians that Laura talked about, record number of trainings that she just addressed, and the growing engagement on the intervention side. So we're actually feeling quite good about the second half.

  • Matthew O'Brien - Analyst

  • Got it. Thanks so much.

  • Operator

  • Andrew Ranieri, Morgan Stanley.

  • Andrew Ranieri - Analyst

  • Maybe to start. Anshul, this one is probably for you. But just on the adjusted EBITDA guide positive for the fourth quarter. Just maybe as we think longer term for 2025, maybe how should investors maybe think about the puts and takes of breakeven next year? I mean, I think consensus is already there on an adjusted EBITDA basis.

  • But it sounds like you have more new products coming, maybe some incremental sales reps hiring, but how should we be thinking about, or how are you thinking about balancing, maintaining kind of this 19%, 20% growth with some of the OpEx investments that you'll likely continue to have to make next year?

  • Anshul Maheshwari - Chief Financial Officer

  • No. I appreciate that question, Drew. So we are really proud of the operating leverage, we've seen in the business, and we've incrementally converted growing portion of our gross margin dollars to adjusted EBITDA. And the trend that we see for the back half gives us confidence in the breakeven for the fourth quarter.

  • Now at a very high level when you look beyond 2024, we expect annual revenue growth to continue to exceed OpEx growth going forward. So you may see some quarterly seasonality for Q1 or sorts, but we're feeling pretty good about that trend continuing and allowing us to report positive adjusted EBITDA annually in the future years.

  • Now, you're right. We do have a huge amount of opportunity ahead of us. So we will continue to strike that right balance by making targeted investments in the sales force expansion and R&D, but we expect to see significant leverage on the OpEx side from a G&A standpoint.

  • And even on R&D, it's not going to be at the same pace as revenue growth, right? You get some scale benefit there too. So I think the business is set up really well going into 2025 in terms of being able to sustain adjusted EBITDA positive on an annual basis.

  • Andrew Ranieri - Analyst

  • Got it. It's encouraging. And maybe, Laura, for you. It sounds like the trauma product is still on track for the fourth quarter. I think there was like a new TORQ 510(k), maybe about a month ago that hit FDA's website. Just any more color on the product or how you're thinking about the fragility fracture market?

  • Laura Francis - Chief Executive Officer

  • Yeah. Thanks, Drew. And yes, we are really excited about the new trauma product. As we've said, we're expecting a Q4 launch. And while we've seen success with TORQ, the new product that we're planning to launch in the fourth quarter, it's -- it's specifically designed to fit the workflow of trauma surgeons.

  • What's also been interesting is that we're attracting the attention of multiple regional distributor who are expressing interest in agency partnerships around those trauma surgeons to get access to our unique solutions. So it's a planned portfolio expansion. And combining that with the use of our hybrid commercial model is going to allow us to capture this trauma opportunity as well as contribute to our long-term revenue growth.

  • Andrew Ranieri - Analyst

  • Thanks for taking the questions.

  • Operator

  • Richard Newitter, Truist Securities.

  • Unidentified Participant

  • Hi, guys, Thanks for taking the quesitons. This is Ravi in for Rich. Can you hear me okay?

  • Laura Francis - Chief Executive Officer

  • Yes.

  • Unidentified Participant

  • Hi, thanks. So I just wanted to kind of get into the accelerating guidance commentary. Strong procedure volumes, kind of favorable trends you mentioned in the script. How do we think about that from kind of a price volume breakdown as it comes to reconciling the growth rates with your guide? And then I have a follow-up.

  • Anshul Maheshwari - Chief Financial Officer

  • Happy to take that. On the guidance side in the back half of the year, our assumption's depending on the range, right? So on the low end of the range, our assumption is sort of a low single-digit ASP decline. Now we've done significantly better than that over the last several quarters where our ASP has been fairly stable. And the rest would come from volume. So if you look at the high end of the range, it's similar ASP trends that we've seen thus far in the year and the rest is volume on the low end, it's 1% to 3% ASP pressure and the rest is coming from volume.

  • Unidentified Participant

  • Great. And then just maybe if you could help us think about -- you have access to a number of different physician channels at this point with the different product launches that are coming out. Help us think about kind of what you're seeing on a macro level around procedures, new product launches, maybe throughput in terms of how you're getting access to the doctors, in terms of the procedures you're doing, maybe on the ortho side and the interventional side?

  • And then any color you could give around how you plan to address the trauma doctors as well? That would be great.

  • Laura Francis - Chief Executive Officer

  • Yeah, I'm happy to take that question. So as we mentioned, we're continuing to see an increase in the number of physicians that we're working with. It was a -- we were at a record at the end of the quarter with over 1,150 active physicians. And we do have a number of different call points. But simplistically, what we are seeing is that we are targeting primary SI joint fusion with our direct sales force with both spine surgeons, as well as interventionalists, and seeing continued strong growth with spine surgeons, and then excitement to start doing our procedure with interventionalists. So that continues to be the core that's driving the business.

  • Pelvic fixation with our Granite 9.5 product and the recent launch of that product continues to drive our growth in pelvic fixation in a number of different ways, addressing constructs and need potentially for a smaller diameter implant or potentially using four implants in those particular cases. And what has become fairly typical there is we're using a hybrid model in those cases, where you continue to have a direct sales person from SI-BONE involved, but also third-party agents that are actually covering those particular cases. And that's helping us to drive the increase in sales rep productivity that you're seeing, so that's the second procedure type.

  • And then finally, the third one is the area of pelvic trauma. And this is still a relatively small area for the business, but growing very nicely. We're really excited about the launch of this new product in the fourth quarter of this year. And that's another area where we have a hybrid commercial model, where we have our direct sales force working closely with third-party agents, typically those that work more with trauma surgeons in order to drive the growth of that business.

  • So those are the three different areas, and those are the ways that we're approaching them from a commercialization perspective.

  • Operator

  • Xuyang Li, Jefferies.

  • Young Li - Analyst

  • Hi. Great. Thanks so much for taking my questions. I guess to start, I wanted to get a little bit more color and details on the new product launches from this year. And it sounded like Granite 9.5 with launches and really going really, really well. If you can share some additional details, that would be great.

  • Simply for INTRA, any incremental color would be helpful. And how much are those products sort of baked into the second half guidance? Thanks.

  • Laura Francis - Chief Executive Officer

  • Yeah, I'm happy to take the first part of that question. So we've launched two products thus far in the year. And then as I've mentioned a couple of times on this call, we have a third one that's going to be coming by the end of the year.

  • So first product that we launched was our product INTRA earlier this year. And that was dorsal allograft product targeted primarily toward interventional lists. We've seen a nice uptake on that product, but most of the sales that we have seen thus far in interventional are actually using our TORQ, product our lateral transfixing product in those interventional cases, which is what we had expected. We just wanted to have that additional solution interventionalists who are interested in a bone product instead of a device.

  • And then we are very pleased with what we're seeing with Granite 9.5 right now. So within the lumbar fusion market, we're building on the success of our original Granite product. And we're really encouraged by the surgeon interest in using 9.5 in shorter constructs, which is around 100,000 annual procedures in those particular cases.

  • Within deformity, we also see Granite 9.5 as an opportunity to engage a subset of surgeons who, one of the smaller diameter implant. And then in certain instances, we're seeing our existing active deformity surgeons use Granite 9.5 to enable 2 points of fixation on either side, which obviously increases our ASP.

  • So I'm very happy with what we're seeing from an interventional perspective overall with that launch. And then as well with Granite 9.5, building on the the base that we had formed with our original Granite product. And also looking forward to the launch of our our trauma product in the fourth quarter.

  • I'll have Anshul speak a little bit more on the other part of the question.

  • Anshul Maheshwari - Chief Financial Officer

  • Yeah. So on the guidance side, as you know, we've been using 10.5 in the degenerative spine space. So we've had a short construct market already developed in the last couple of years. Granite 9.5 now opens up that market, because we're now being able to go after the S1 opportunity, both in primary and revision cases. So that is upside there. That is baked into some of our guidance.

  • Obviously, we're being very thoughtful about how we bake that in because we're still rolling out Granite in the third quarter, we did a very piloted rollout in the second quarter, as you recall. So we want to be very thoughtful there.

  • On the interventional side, obviously, talks doing very well there, like Laura said, INTRA -- we're seeing pockets of adoption based on reimbursement, but our assumption always was the broad adoption will be driven by the outcome of the dropped LCD. So we're not incorporating much of that in our current guide at this point, which we think is the right approach.

  • Young Li - Analyst

  • All right. Thanks very much for that. I guess just a follow-up. It looks like on your presentation, you updated the iFuse patent, extended it by about five months. I think most of the iFuse coming from iFuse-3D, which has about 10 years left. You also have approach INTRA that has about 10 years left on it as well. I guess I'm just kind of curious, in light of the iFuse patent expiration, I wanted to get an update on the competitive dynamic currently.

  • Laura Francis - Chief Executive Officer

  • Yeah. I mean, we pride ourselves on being a company that identifies unmet clinical needs. And then what we do is develop innovative products, and we patent those products. And so we are constantly looking at our patent portfolio and patent protecting all of the products that we're working with.

  • As you had mentioned, with iFuse-3D, we have patents that actually run through 2035. And that is the vast majority of sales of our triangular titanium implants. But we continue to also try to extend at least a little bit the patents on the original iFuse. But most importantly is, iFuse-3D accounts for almost the entirety of our triangular titanium implant revenue and it's patented through 2035.

  • We also did receive a new patent for the broach instrument last -- recently, which extends into 2034, which also impacts our core iFuse franchise. So we've continued to build the patent portfolio with our iFuse implants, as well as Granite, which is patented through 2039 and TORQ, which is patented through 2040.

  • Operator

  • Caitlin Cronin, Canaccord Genuity.

  • Caitlin Cronin - Analyst

  • Hi. Tanks for taking the questions, and congrats on a great quarter. Can you just provide a little bit more color on the updated commercial strategy that you outlined? And maybe quantify any more reps that you expect to add? And also any distributors you expect to onboard through the process?

  • Laura Francis - Chief Executive Officer

  • Yeah, happy to do that. So under the leadership of Tony Recupero, we've built the best direct sales force in the industry. And we continue to see strong interest from reps wanting to join our team because of the differentiation of our company compared to others, evidence backed, and differentiated portfolio as well as a high-performance culture.

  • So with the evolution of our portfolio, we've been leveraging this hybrid commercial model. So in particular, engaging third-party agents, as well as adding more associate level reps to create additional capacity for our territory managers. And they're our most valued asset. And what we want to do is ensure high-quality service and support for our physicians, and basically just effectively capture the demand for our solutions across multiple target markets.

  • So if you think about it longer term, the hybrid model has allowed us to deliver average revenue growth of over 20% over the last three years and nearly double our revenue per territory to $1.7 million during that period. And it's also driven dramatic operating leverage in the business. So over the next couple of years, we're going to continue to use the hybrid model, while selectively adding sales reps.

  • So, what we envision is that we're going to get to 100 territories with approximately $2 million of sales rep productivity a piece, which will build a $200 million business. So you should expect to see us end 2024 with a handful of new territories.

  • Caitlin Cronin - Analyst

  • Got it. That's helpful. And then just a couple of questions on the intervention with call point. How does the appointment of Thomas West really help you shape your interventional strategy going forward? And I also remember you mentioning recently that the target interventional surgeons was 1,000 versus the initial 45,000 -- 4,500 that you initially targeted of the interventional surgeons. Do you see opportunities to expand to the extra 3,500 that are just doing the needle-based procedures over time?

  • Laura Francis - Chief Executive Officer

  • Yeah. So asking the question about Tom and then also expansion to those 4,500 interventionalists. Our focus from the inception of the company has been on surgeons. It's orthopedic and neuro spine surgeons, in particular, and there are around there are close to 8,000 of those that we're targeting. And if you look at the number of physicians that we've worked with, we still have a long way to go with those particular surgeons.

  • But we also recognize that the interventional market -- our solutions are similar, but the market is different. The call point is different. And so Tom, with his experience with Nalu Medical, is a really nice addition to the Board of Directors to help us to to think about that new call point and strategize around it.

  • In terms of who we're targeting from an interventional perspective, the 1,000 that we're talking about, are the ones that are really going to be doing the lateral TORQ transfixing procedure. And so those really have been the focus for us with our initial rollout. And what we're seeing is that, that come to fruition that we are seeing more of those positions doing those procedures but primarily with TORQ.

  • In terms of getting to the additional 3,500 in that group, we do think that there's an interesting opportunity that's here. And that with some of the additional products that we currently have like INTRA, that it does give us the opportunity to also penetrate that market, too.

  • Caitlin Cronin - Analyst

  • Thanks so much.

  • Operator

  • David Turkaly, Citizens JMP.

  • David Turkaly - Analyst

  • Great. Laura, given your comments on INTRA and TORQ, and then also sort of the increase we keep seeing in active docs and physicians, I'm curious would you call out do you have interventionalist in that 1,150 today?

  • Laura Francis - Chief Executive Officer

  • Short answer to that is yes, Dave. So we're seeing a nice adoption by interventionalists as well as our spine surgeons that we work with on our other procedures.

  • David Turkaly - Analyst

  • Got it. And then I appreciate the color you gave on 9.5 and the facility from the docs to possibly use even more then sort of two, maybe up to 4fourimplants. I just wanted to clarify one thing. Is that also new technology add-on payment? Is that relevant for that as well?

  • Laura Francis - Chief Executive Officer

  • It actually is, yeah. So the Granite family, the NTAP actually applies to the original product. as well as the new Granite 9.5 product. So it has that same benefit where the hospital using our Granite products can receive up to around $9,800 of additional payment for pelvic fixation using Granite.

  • David Turkaly - Analyst

  • Thank you very much.

  • Operator

  • David Saxon, Needham & Company.

  • Joseph Conway - Analyst

  • Hey, everyone. This is Joseph on for David. Congrats on the record quarter. Just maybe another question on interventionalists, just to try to understand the channel a little bit more. Does that have a different pattern as it relates to ramping SI procedures once the doctors are trained? I guess -- and just any differentiating factors between the interventionalist and spine surgeons would kind of help us understand a little bit better.

  • Laura Francis - Chief Executive Officer

  • Yes. So there -- we're really going after two huge markets here, right? So the SI joint fusion market is a market that's over $2 billion in total. And as I said, you have around 8,000 spine surgeons that are targets to perform SI joint fusion, and you have approximately 4,500 who are interventionalists. Also, as I said, we're really going after around those first 1,000, and we're primarily leading with our TORQ products. So the lateral transfixing product, that is paid under 27279.

  • In terms of how to approach the surgeons versus the interventional spine, it's been similar in a lot of these cases just because we're looking at those who already feel very confident and comfortable with procedures. As we penetrate deeper into the interventional market, into that 4,500, we definitely will think differently.

  • It's our intra product, for example, that may be more of interest to those particular physicians. But overall, the way that we have approached this is we've approached it with our direct sales reps, selling directly to the spine surgeons as well as the interventionalists and leading with our TORQ device.

  • Joseph Conway - Analyst

  • Okay. Great. Very helpful. And then I guess, EBITDA, adjusted EBITDA profitability, you guys are getting there pretty soon. When you do get to EBITDA profitability, how far out should we kind of be thinking about free cash flow, so profitability?

  • Anshul Maheshwari - Chief Financial Officer

  • Yeah. So I can take that question, Joseph. So we have high gross margins driven by higher ASP. And our asset model is relatively light, which is very different from what you see in traditional spine companies where you have a significant capital outlay to support growth.

  • And as you've seen in the recent quarters, our reduction in cash usage has been somewhat in line with our adjusted EBITDA improvement. And given our expectation on adjusted EBITDA improvement on an annual basis going forward, that should continue to translate into improved cash flow trends as well.

  • Now, some of that may be impacted by timing of new product launches and how we're putting capacity into play. But we feel very good about that cash flow trajectory once we get to that adjusted EBITDA breakeven. So that's number one.

  • And then when we look at our overall profile with over $150 million of cash and ability to maintain that adjusted EBITDA improvement going forward, we feel very good about having the financial resources to be able to fund all our growth going forward.

  • Okay. Thanks. And congrats on the record quarter.

  • Operator

  • Ross Osborn, Cantor Fitzgerald.

  • Ross Osborn - Analyst

  • Hey, guys, Thanks for taking the questions. Congrats on the quarter. So regarding the fourth quarter launch of a new product in the public trauma market, will this be an offering that will require real-world data? Or do you expect to see a pretty quick adoption rate?

  • Laura Francis - Chief Executive Officer

  • Yeah, good question. And we have already been working in the trauma market since we launched TORQ. So we launched TORQ in, I believe it was April of 2021. And so we have been selling to trauma surgeons. They have been using the product for sacral insufficiency fractures. And so with that success, we do have data that we can share with these particular surgeons.

  • So overall, coming into the second half of the year, I think we're set up really well. We're seeing the benefit from strong demand trends, and we're capitalizing on accelerating demand within the pelvic fixation, market with the rollout of Granite 9.5. We have growing engagement within Interventional Spine with TORQ, and we also have the new product launch targeting the trauma market in the fourth quarter. And then top-line momentum positions us to deliver adjusted EBITDA breakeven in the fourth quarter, which is a major fiscal inflection for our P&L profile.

  • So our company-specific, fundamental demand trends, and the anticipated additions to our portfolio over the coming years, it gives me confidence that we have the platform to deliver strong and profitable revenue growth going forward. The strong performance this quarter and the consistency of our strong results in the last several quarters across revenue growth, surgeon engagement, operating leverage. It's an outcome of our focused strategy to transform the business from a single product to a multi-modality med device platform with large unmet target markets.

  • Ross Osborn - Analyst

  • Great. And then in terms of STACI, it's nice to see the positive interim results comments there. But would you remind us of the rough time lines associated with the next milestones?

  • Laura Francis - Chief Executive Officer

  • Yeah. So with STACI, we have already completed enrollment in that particular study. We have the set of results. And I believe that our plan is to have a publication out by early 2025 with STACI.

  • Ross Osborn - Analyst

  • Got it. Thanks for taking the questions.

  • Laura Francis - Chief Executive Officer

  • Thank you.

  • Operator

  • And I'm not showing any further questions at this time. I'd like to turn the call back over to Laura for any closing remarks.

  • Laura Francis - Chief Executive Officer

  • I just want to say thank you, all, for your participation in our call today. And we look forward to seeing you at upcoming conferences and on deal roadshows.

  • Operator

  • Ladies and gentlemen, this does conclude today's presentation. You may now disconnect, and have a wonderful day.
