Alphatec - Q2 2024
July 31, 2024
Executive Summary
- Delivered strong top-line growth and first positive adjusted EBITDA: total revenue $145.6M (+24.5% YoY; +5.1% QoQ) and adjusted EBITDA $5.6M (3.8% margin), aided by 27% surgical revenue growth and 10% YoY increase in revenue per case.
- Raised FY24 guidance: total revenue to $602M (from $601M), surgical to $537M (from $536M), and adjusted EBITDA to ~$25.5M (from $23.0M); EOS revenue maintained at $65M.
- Near-term headwinds: higher 2024 cash use now $125–$135M (vs $100–$110M prior) on elevated DSOs and inventory inefficiencies; Q3 cash use ~$25–$30M, Q4 cash generation $5–$15M expected.
- Strategic catalysts: commercial launch of EOS Insight (AI-enabled end-to-end spine platform) and record 244 surgeon training engagements; management emphasized continued share gains and territory upgrades despite short-term volume lumpiness.
What Went Well and What Went Wrong
- What Went Well
- Achieved profitability inflection on an adjusted EBITDA basis: $5.6M with 650 bps YoY margin expansion; CFO cited 30% drop-through on YoY revenue dollar growth driven by SG&A, R&D, and gross margin leverage.
- EOS Insight launched on time; management framed it as integrating standardized EOS imaging and AI across pre/intra/post-op workflow to improve predictability and outcomes: “EOS Insight… replaces archaic clinical practices to improve patient outcomes”.
- Commercial momentum: surgical revenue +27% YoY, 20% growth in new surgeon adoption, and a record 244 surgeon training engagements underscoring demand.
- What Went Wrong
- Working capital pressure increased: 2024 cash use revised to $125–$135M (from $100–$110M) due to ~5 extra DSO days (~$10M) and inventory inefficiencies (~$15M).
- Temporary supply constraints (one biologics offering and one expandable implant) limited upside; constraints now resolved heading into Q3.
- Territory upgrades created near-term lumpiness: case volumes +15% YoY (vs +23% in Q1) as incumbents wound down faster than expected; mix skewed to higher-ASP lateral driving +10% ARPP growth.

Good afternoon, everyone, and welcome to the webcast of ATEC's second quarter financial results. We would like to remind everyone that participants on the call will make forward-looking statements. These statements are based on current expectations and are subject to uncertainties that could cause actual results to differ materially. These uncertainties are detailed in documents filed regularly with the SEC. During this call, you may hear the company refer to non-GAAP or adjusted measures. Reconciliations of these measures to U.S. GAAP can be found in the supplemental financial tables included in today's press release, which identify and quantify all excluded items and provide management's view of why this information is useful to investors. Leading today's call will be ATEC's Chairman and CEO, Pat Miles, and CFO, Todd Koning. Now, I will turn the call over to Pat Miles.
Pat Miles (CEO)
Thanks much, Danica, and thanks everybody for your interest in engaging in the call. So, I will jump right into the Q2 2024 highlights, and I would say it's another deliberate step in fulfilling the commitment to profitable long-term sales growth. And so, finished the quarter at a total of $146 million in total revenue. The total revenue percent growth was 25%, 27% surgical revenue growth, which I expect to be best in class. 20% growth in new users, which I would say speaks to the expansion metrics, 15% surgical volume growth. I think that's a metric that reflects kind of the nonlinear ramp as we continue to upgrade our sales force.
Caitlin Cronin (Analyst)
One that I love is the 10% growth in average surgical revenue per case. That speaks to the conveyed elements of our procedural strategy and the buy-in to that, which is really good. We inflected to profitability with an adjusted EBITDA of $5.6 million. We had 244 surgeon training engagements fueled by our footprint expansion, so, there's a lot going on there. I think the $50 million invested is a confidence proxy for our route forward, and so, expanding just the footprint to support growth. And then last but not least, I think the thing that I'm gonna spend a bunch of time on during this call, really, is the EOS Insight launch on time.
And I will explain the relevance of that, but it reflects the work of really hundreds of people over a multi-year period. And so, it was audacious, and I'm exceedingly proud of it. And when we acquired EOS, our vision was to translate the most coveted image in spine into an informatic, and I would tell you, we've done it. So, if you look back or think back, we came to ATEC to create a spine juggernaut, and we wanted to do it creating value by advancing the field of spine. And we are committed to a deliberate spine-focused long walk. And I think that the revenue reflection of this strategy, I think, is undeniable.
We have created clinical distinction, so, we are distinguishing ATEC technologically through really two really core means. We've architected procedures, which is reflected in the assembly of products, and then concentrated on what informatic creates predictability in spine. And I think that it's highly relevant for this time of year and this call. The second thing that we've been able to do is compel adoption, and that just means increasing surgeon users by improving surgery. So, if the clinical distinction is what we know it to be, the likelihood for somebody to be inspired to use our stuff is high. And clearly, what else is required is an elevated, expanded distribution network, and so, doing our best to attract talent with distinction-driven surgeon demand.
And so, I would tell you that those are foundational to our success, and we love to revisit them because it's what's driving the company. So, when we talk about procedural architecture, I will tell you that we are steeped in a history of value creation via informatic integration. What that means is their information where we could mitigate clinical variables to improve surgery? And when you start to think about the ascension and the prowess that's been created in lateral, it is our growth driver. What's done that is a key piece of information that enables surgeons to really know things that they wouldn't have known otherwise. And so, when you think about lateral surgery and you go from skin to spine, the most relevant anatomy of concern is neurologic.
And so, to have a tool to be able to say, "Hey, I know where the nerve is, and I know what the health of the nerve is," is really kinda foundational information that drives surgeon decision-making. I hope that what this does is really kinda serves as an example or a proxy for how informatics influences the predictability of spine surgery. 'Cause from this, what we've done is I would tell you that we've learned. And what we've learned is that really what precludes predictability oftentimes is information, and so, measurable information that mitigates variables. It is the why behind our investment thesis into the most comprehensive, integrated, end-to-end automated information ecosystem in spine. Most importantly, it'll drive improved spine care. Spine's yearning for improvement.
Spine is hugely complex, and when you think about it as compared to other orthopedic surgery, it is less durable.... The revision rates in both short and long segment surgery are unacceptably high. If our job as a spine provider is not to make that better, I don't know what our responsibility is. There's a bad joke in spine, and it talks about there's two kinds of surgeries-- surgeons. There are the ones that create deformity and the ones that fix them. I got to tell you; we want to be in the latter category. The last thing a prospective patient needs in contemplating spine surgical intervention is a double-digit likelihood that there's going to be future surgery.
And so, you know, our ability to delve into how we minimize that potential is a value creator. We have demonstrated how using information to mitigate variables furthers predictability. We have done this with EOS Insight through focus on pre, intra, and the post-op experience. This is what we mean by end-to-end. It starts at the pre-op and ends at the post-op. EOS Insight is just the beginning of a fully integrated tool that improves spine care. Let's start with an explanation around the preoperative experience. And so, the reason most surgeons do not plan surgery is that it is onerous. It often takes a very long time, and it's imprecise. You're dealing with non-standard imaging modalities, where magnification and other challenges undermine accuracy.
In short, it is a lot of work for little precision and objective value, so, it's just not done often. The beauty of EOS Insight is it provides AI automated alignment measures that inform the surgical plan. It is a computer-generated assessment that precisely measures a patient's spine alignment parameters. If alignment is the greatest correlative to durability or a successful long-term outcome, we believe this to be a requirement of surgery. So, EOS Insight automates this task with precise computer-generated alignment measures that inform a 3D model and subsequently a surgical plan. The surgical plan illustrates the optimal contract that maximizes the highest likelihood for plan achievement. Then, the 3D plan contemplates what implants are most applicable to achieve a normative age-related restoration of spine alignment. Once this is determined, as expected, EOS Insight provides for the option of a custom implant.
And so, the preoperative sophistication is efficient, it's expedient, it's automated, and so, the work required is little to none. And so, I think that that's an exceedingly attractive part of the preoperative effort. So, when you start to move it to the intraoperative phase, and once the plan is complete and imported into the intraoperative experience, then what you start to do is you say, "If the plan calls for lateral surgery, our ecosystem will have Valence, which is the navigation robotic system, assembled to SafeOp, which enables you to look where the nerve is and the health of the nerve." So, it assembles those pieces of technology and really that's the start of kind of integrated tools that reflect innovation.
So, the EOS operative plan is automatically loaded into our EOS intraoperative alignment system, IOA. And so, what that system does is it takes intraoperative images and measures them compared to the preoperative surgical plan. It enables information like reciprocal change. Do I understand how I've effectuated the spine? And it enables them to achieve the operative experience prior to leaving the operating room. So, these informatic tools ultimately combine best-in-class informatics with best-in-class procedural specific tools. And so, it is no coincidence that the most coveted understanding of the lateral requirements are here at ATEC. And I would tell you, they are integrated with an informatic system and a procedural specific set of tools that ultimately creates predictability.
A driver of our growth has included an increase in, well, in average selling price. And when you look at average selling price, what you do is you say, "Gosh, did we assemble tools to ultimately reflect on the requirements of surgery?" So, an assembled procedure. The other reflection is in surgical complexity. And so, we believe that our ecosystem will be a key driver to continue to drive surgeon confidence, availing more and more complex surgery, which really can lead you to the realm of deformity. And so, the ecosystem that we've created will be highly relevant in deformity surgery, not only in the navigation robotics piece, and what we've done is added what's called facilitated MEPs for spinal cord monitoring. If realignment is a key driver of deformity surgery, intraoperative reconciliation to a surgical plan fulfillment is a must.
Deformity surgery is intended to provide a restorative impact. Our influence in both adult and AIS surgery, in essence, adolescents, is in the earliest of phase. Our work on patient-specific implants, positioners, derotation tools, and the like is really just getting going. So, in my mind, a ton of tailwind in the work that we're doing. I would say that another extremely relevant reflection of just the automation of EOS Insight is the data collection element. Collecting data from an automated source requires no special activity. So, again, the work requirement is very limited. The beauty is that it provides insights that improve future surgery. Some call that predictive analytics, but in simple speak, it is a way to ultimately improve future surgery.
Mitigating variables through patient and practice insights driven from automated data collection, at the very least, makes for more informed surgery. We believe the data collection aspect of the EOS Insight tool to be a significant driver of future value. So, I think so often people are introduced to things and they're introduced to them more theoretically than practically. What we want to do is really kind of show you the plan in action and would love a quick shout-out to Dr. Craig McMains and Dr. David Schwartz at OrthoIndy. They ultimately completed the first initial case of EOS Insight. The first patient was scanned in the EOS Edge. So, you see the automated alignment measures.
So, as I said, scanned in the EOS Edge, generated an AI-automated alignment report, which is opened in the portal. The automated alignment then informed the 3D surgical plan. The plan provides for normative values, for the specific patient and generates a patient-specific custom surgical plan. That plan then informs the patient-specific rod. And so, you can see down at the bottom is a patient-specific pre-bent rod. All of this is done preoperatively in a highly automated, efficient manner, so the expedience of this is very strong. At that point, what we do is we take the plan, and we port it into the operating room. By importing it, we import it to the tool that enables an intraoperative reconciliation against the preoperative planning measures.
So, all of this is a very expedient exercise that takes the pre-op, integrates into the intra-op, and enables the surgeon to understand exactly where they are in real time in the operating room. And then the beauty is the postoperative phase, there's an opportunity to compare the objective data from the preoperative alignment to the plan to the result. This is the result of a company that is committed to moving spine surgery forward. The complexity of this effort and the on-time launch is something for which we are extraordinarily proud. Creating clinical distinction or the fulfillment of our clinical vision is really coming to fruition right before our eyes. And so, now the effort becomes in compelling more converts. And so, that's happening. As you can see, it's happening.
We are compelling surgeon adoption in Q2. We had a record-breaking surgeon training that reflects adoption, where we are investing in long-term momentum building. So, we had 244 surgeons, and as stated, 20% growth in surgeon users. So, I think clearly that we're making progress as it relates to compelling surgeon adoption. I think-
Something went wrong. Please try again.
That was my friend, Siri. I think the other element that I think is highly important is, are we putting the right people around the company from a field perspective? So, recruitment continues and expands our ability to meet surgeon demand. Market disruption continues to be our friend and is industry wide. We will continue to capitalize on that market disruption. We have a strong funnel of experienced talent to expand and upgrade our sales footprint. And we believe, again, that the disruption is a multi-year tailwind. As you'd expect, however, it's a nonlinear walk. I think, you know, another interesting thing is if you look at the demographics of the recruitment class of our year-to-date recruiting efforts in the class of 2024, there's a lot of activity going on.
What provides people confidence, however, is the 23% growth in established territories. It's one of those things where it's like many of us who have been here for a long period of time have started from nothing and created, again, a monstrosity of growth. And I think that it gives people a lot of confidence when they join the family that they're able to do the same. So, as you would expect, we are executing well against our long-term commitments and are excited about how we'll continue to walk toward our 2027 commitments of $1 billion in revenue in 2027, an Adjusted EBITDA of $180 million, an Adjusted EBITDA margin of 18%, and free cash flow of $65 million.
And so, I think that we have a heck of a lot of momentum. There are so many things going on clinically. That is the cornerstone of who we are as an organization, and I'm thrilled with where we are at this point in 2024. So, with that, I'll turn it over to Todd.
Todd Koning (CFO)
Well, thank you, Pat, and good afternoon, everyone. We appreciate you joining us on the call today. I'll begin with revenue. Second quarter total revenue was $145.6 million, reflecting 25% growth compared to the prior year and up 5% sequentially. The $145.6 million in revenue is comprised of $130 million in surgical revenue and $15.5 million of EOS revenue. Second quarter surgical revenue of $130 million increased 27% year-over-year against a strong comparable of 41% growth in the prior year period. Surgical revenue growth was robust across the entire portfolio, particularly in lateral and expandable implants.
Caitlin Cronin (Analyst)
We drove procedural volume growth of 15% and revenue per procedure growth of 10% compared to the prior year. Both metrics have shifted slightly relative to recent trends due to the meaningful sales force upgrades and additions that we are executing. We are upgrading some existing territories with new sales agencies to more strategically reflect the ATEC brand and align with the surgeons who are compelled by our procedural thesis. That generally increases average revenue per procedure in the territory. Yet, as new coverage ramps up, volumes related to the incumbent coverage wind down. As a result, there may be quarter-to-quarter lumpiness in the underlying dynamics of revenue growth as the upgraded territories ramp. Specific to the second quarter, case volume growth was not as strong, while average revenue per procedure growth exceeded recent trends....
Adjusting for this dynamic in the quarter, volume growth would have been about 300 basis points higher at 18%. Our long-term expectation is that the upgraded agencies will grow the territories, contributing over time to sustainable improvements in territory revenue. The 20% growth in Q2 surgeon adoption corresponds well with this. Surgical revenue growth in the second quarter was also impacted by an additional, more transient dynamic. We outgrew supply of one of our biologics offerings and one of our expandable implants. We have addressed both constraints and now have full supply available. EOS revenue in the second quarter was $15.5 million, up 6% compared to last year. Next, I'll turn to results for the remainder of the P&L.
Second quarter non-GAAP gross margin was 71.2%, up 190 basis points compared to the prior year. The year-over-year increase continues to be driven by improved EOS gross margin and volume-driven leverage of our Memphis distribution facility. Second quarter non-GAAP R&D was $13.5 million and approximately 9% of sales, compared to $13.1 million and 11% of sales in the prior year. We delivered 190 basis points of R&D leverage while continuing to invest in innovation and the future growth of the business. Non-GAAP R&D spending was roughly flat sequentially. Non-GAAP SG&A was $100 million and approximately 68.9% of sales in the second quarter, compared to $81 million and 69.1% of sales in the prior year period, an improvement of 20 basis points.
Included in SG&A is the expected step-up in depreciation related to the purchase of instrument sets. As a percent of sales, depreciation increased about 250 basis points year-over-year. Excluding that impact, SG&A improved by 270 basis points. Two-third, two-thirds of the improvement was driven by variable selling expense, with the balance driven by infrastructure leverage. Total non-GAAP operating expenses amounted to $114 million and approximately 78% of sales in the second quarter, compared to $94 million and 80% of sales in the prior year period, demonstrating 210 basis points of operating leverage year-over-year. Total non-GAAP operating expense was down $1 million sequentially. In the second quarter, we inflected a positive adjusted EBITDA of $5.6 million and 3.8% of sales.
This is compared to a loss of $3.1 million and 3% of sales in the prior year. 650 basis points of improvement. Drop-through of the year-over-year growth in revenue dollars to Adjusted EBITDA was strong at 30%. That improvement was driven by 270 basis points of SG&A leverage, followed by 190 basis points of R&D leverage and 190 basis points of gross margin leverage. The consistent Adjusted EBITDA margin expansion that we are driving is aligning solidly with our expectations. This gives us confidence that profitability will continue to expand in future quarters and fuel self-funded growth as we execute to our long-range plan commitments. Turning to the balance sheet, we ended the second quarter with $100 million in cash. Debt at carrying value was $531 million.
Free cash use totaled $45 million, with over $50 million deployed into inventory and instruments that support the expansion of our distribution footprint and new product launches. Managing the efficiency of those assets being deployed is proving to be slightly less linear than anticipated. As a result, working capital needs have been higher than we initially forecasted. Adopting more conservative working capital assumptions for the balance of the year will result in an expected full year cash use ranging between $125 million and $135 million. This is $25 million higher than the $100 million to the $110 million previously expected. Approximately $10 million of the change relates to elevated days sales outstanding, while the remaining $15 million relates to inventory inefficiencies.
We expect Q3 cash use of approximately $25 million-$30 million, with Q4 inflecting cash generation of $5 million-$15 million. With a fully drawn revolver, we expect to end the year with approximately $100 million in cash on our balance sheet, which, as we've communicated, is sufficient for us to run the business. We continue to expect to achieve free cash flow breakeven in 2025. Turning to our updated outlook for the full year of 2024. As Pat mentioned, the leading indicators of future revenue growth were exceptional in the second quarter, with record surgeon training engagements and growth in new surgeon adoption of 20%. Both are testament to the surgeon demand that ATEC clinical distinction is earning in the field. We expect that to fuel total revenue growth of 25% to approximately $602 million.
That includes 2024 surgical revenue growth of approximately 27% to $537 million, and EOS revenue of approximately $65 million. Calibrating for the impact of territory upgrades that I mentioned earlier, we expect surgical volume growth to continue to be the greatest contributor to surgical revenue growth, increasing at a high teen % rate for the full year. Territory upgrades will also drive increased growth in revenue per surgery, so we now expect a high single-digit % growth rate for the full year. Sales growth continues to fuel leverage across our business, and with a second quarter outperformance, we now expect full year Adjusted EBITDA of approximately $25.5 million, which equates to 610 basis points of margin expansion.
That implies an approximately 29% drop-through of the year-over-year growth in revenue dollars, a significant acceleration compared to the 22% drop-through in 2023. I'll close my comments with this view. This chart depicts the deliberate and substantial profitability expansion that we have demonstrated over the last 2.5 years. Over that time, Adjusted EBITDA has increased substantially from a loss of $13 million and 18% of sales, to a contribution of $6 million and 4% of sales, over 2,000 basis points of improvement. Importantly, we are not done. We recognize that profitability and cash generation are crucial to value creation. The progress that we have delivered, along with the drivers of that progress, contributing the way in which we intended, give us confidence in our future commitments.
There's a lot of work left to do and a lot to be excited about. As usual, we have an active IR calendar in the next few months, and are looking forward to connecting with you. With that, I'll turn the call back to Pat.
Pat Miles (CEO)
Thanks much, Todd. I would just conclude the call by saying, prior to Q&A, saying we have a track record of execution. This has been a deliberate, spine-focused long game. And so, we're executing via a procedural strategy. I think we have just launched the most unique ecosystem in all of spine to inform better spine surgery, and I think it's unquestionable that we are advancing the field. And so, with that, we will take questions.
Operator (participant)
Great. We will now open the floor up for questions. To accommodate everyone on the call today, please limit yourself to one question. In order to ask a question, press Star, then the number one on your telephone keypad. If you would like to withdraw your question, press Star One again. Thank you. The first question comes from Vik Chopra with Wells Fargo. Please go ahead.
Vik Chopra (Analyst)
Hey, good afternoon, and thanks for taking the questions. So, just on the cash burn, obviously higher than we were expecting. So just wanted to confirm, you're now expecting $125 million-$135 million cash burn for 2024. Is that right?
Todd Koning (CFO)
That's correct.
Vik Chopra (Analyst)
Okay. And just so, I guess to follow up to that, you know, will we need to raise cash again before turning cash flow break even in 2025? And then I had a follow-up.
Todd Koning (CFO)
Yeah, Vik, I think as we look at it, and if you look at the growth next year, I think if you take where the street's at, that's about $123 million of year-over-year revenue growth. You take about 35% of that, you get about $45 million of growth in Adjusted EBITDA year-over-year. So, if you exit this year at $25.5 million, you add $45 million to that, you get about $70 million of Adjusted EBITDA next year. That ultimately funds our working capital and our growth needs and our cash needs for next year. And so, I think going into next year, we feel very good about achieving our cash flow break even with our existing liquidity where we're at today.
Caitlin Cronin (Analyst)
Because ultimately, as we look at our current, our current second half cash burn, thinking that we'll exit the year with a fully drawn revolver at about $100 million going into next year, then with the dynamics that I just laid out in terms of increased adjusted EBITDA on the basis of, drop through of a year-over-year revenue growth.
Vik Chopra (Analyst)
Okay. And then, just to follow up, can you just talk about some of the expected hiring trends for 2024, and any color on the cases of competitive rep recruitment? Thank you.
Pat Miles (CEO)
Yeah, Vik, thanks for the question. I would tell you that it's robust and kind of the approach that we've taken has been as geographic dependent as our needs are. And so, try to provide a little bit of color with the pie chart that just shows you clearly a fair amount from Globus, NuVasive, but also Medtronic, J&J, and the rest. And so, you know, it's been as we could take on as many people as I feel like we want to. The question becomes is: What makes most sense in what geographies at what time? And so, as you appreciate, these things take significant investment.
Caitlin Cronin (Analyst)
We got to make sure that all the instruments and implants are available to them, so that they can start the process of turning on their business. It's a lumpy exercise, but you know, it's happening at the rate that we desire.
Operator (participant)
All right. I think we're gonna go to the next caller. The next caller is Caitlin Cronin with Canaccord Genuity, Genuity. Sorry about that. Please go ahead.
Caitlin Cronin (Analyst)
Hey, everyone. Thanks for taking the questions. Just starting with the territory upgrades, where are you in implementing these, and how many territories have you upgraded or expect to upgrade?
Pat Miles (CEO)
Yeah, it's an interesting question just from the standpoint of where we are as a company. And so, I look at us as having 94% of the market to go. That means we're about a 6% market share holder. And I would tell you that, you know, let's just say, and you know, we're probably well less than a third of the size of, say, a Medtronic sales force. We have opportunities for the next, I'd say, 8 years. And so, again, I think what is mistaken is that the disruption in the marketplace is a several-year tailwind. And the great part is that what sales reps want is they want surgeons who are compelled by new and exciting technology.
Caitlin Cronin (Analyst)
And so, our opportunity to compel sales reps to come along with their surgeons who are inspired by our technology is available to us in spades. What we're trying to do is march toward a operating company, and so, we're doing that in a very methodical way. That means what we're doing is prioritizing those territories that are most opportune for significant, expedient, profitable growth.
Okay, great. Thanks. And then just to follow up on the competitive hires, thanks for noting the breakdown of the hires, but you know, what's the most up-to-date number of the hires? I think the last that you mentioned was 50 reps.
Pat Miles (CEO)
Yeah, we're not gonna share the quarter-to-quarter hiring practices. And, you know, our desire is to get a rep toward a $2 million a year type of a cadence. And so, you could probably do the math and get to a place to where you feel reasonably well about, you know, kinda where we're heading. And so, just from a pure volumetric perspective. But I again would tell you that the people that make up our sales training classes are reflective of the pie chart that we had delivered, and the volume of reps will continue to grow as we run toward a $1 billion.
Todd Koning (CFO)
And Caitlin, I think the greatest indicator for future sales growth ultimately becomes the surgeon adoption that grew at 20% again in the second quarter, and then clearly the surgeon engagements at 244, which was just a very significant quarter's worth.
Pat Miles (CEO)
Yeah. I would say, just to add to Todd's point, which is a great one, which is, you know, you don't get near 250 surgeons to engage in your surgeon training event if there's not interest in what you're doing clinically. And to me, it's such an apparent dynamic, and you know, I feel like we're just trying to be as thoughtful and appropriate as we can with regard to who's coming through.
Todd Koning (CFO)
I think it's reflective of the territory upgrades and additions that we've been making.
Pat Miles (CEO)
Totally.
Caitlin Cronin (Analyst)
Great. Thanks so much.
Operator (participant)
All right, our next question comes from Josh Jennings with TD Cowen. Please go ahead.
Speaker 10
Hi, guys. This is Eric on for, Josh. Thanks for taking the question. Was hoping to just put a finer point on expectations for cash burn through the end of the year. I appreciate the color you gave around cash use through three Q and four Q, but if you could just talk through the drivers that flip into positive cash use in four Q, that would be great. And then what risks do you see to that pathway?
Todd Koning (CFO)
Thank you, Eric. As we look at, you know, the cash use, and maybe I'll just take a minute to talk about the incremental 25 that we're assuming for the second half relative to previous experience or previous communications. That is really due to about $10 million of that due to day sales outstanding. So, if you think about where we exited last year, which was kind of in the high 40s, Q2 was in the low 50s. We're about 5 days different than frankly; I expected us to be at this point in time. So, 5 days times $2 million a day gets you about $10 million.
Caitlin Cronin (Analyst)
The remaining 15 of that has to do with in inventory inefficiencies and really the confluence of growing a business at 25%-30% a year, bringing the size and the volume of new sales agencies on, ensuring that they have what they need when they need it. All of that is a lot of variables in that experience. And so, when you're growing at a rate that we've been growing, there's definitely been some variability there. We've been less efficient in that than I expected, and so that's the drivers behind this. Ultimately, I think we get through that over time, and we improve in those metrics, but I'm now assuming that we don't improve at the end of the year. And so, that's really the dynamic that we're going through here.
You know, ultimately, when you think about the inflection to cash, part of that is we have invested significantly in the sets and the inventory in the first part of this year, as you know. And so that obviously is a trend downwards through the second half of the year. And then as we inflect to profitability, that ultimately drives cash generation. And so, it's really the inflection of those two variables going in opposite directions that really inflect you from cash burn to cash generation. I mean, this is really all about sales growth and profitability growth flowing into cash flow here the rest of the year, and into the future.
Speaker 10
Okay, appreciate that. And then on EOS, with the launch of Insight now in play, I was hoping to just get your thoughts on some of the inbound interest that you and the team have been fielding with that now up and out in the field. And just as a technical question on EOS, I believe it's a software-based platform, so, is upgrading existing EOS systems as simple as just pushing that software out to customers, or is there something more involved required to get adopters up and running? Thanks for the questions.
Pat Miles (CEO)
Yeah. Yep. Thanks, Eric. So just the, I guess, the straightforward one first is, at this point, we go out and it's a software upgrade on the machine. We don't push it yet. There's work going on right now that will enable us to push all software upgrades out. This is kind of our first real significant type of software solution. It's, you know, the reason I spent so much time on it is, it is the reflection of the most coveted image in all of spine being integrated into an informatic tool. And it is very significant.
Caitlin Cronin (Analyst)
You know, maybe much like the narrowness of the way we think of SafeOp to our lateral portfolio, the whole EOS Insight into spine care, I think, is a monumental achievement. And so, it'll play out over time. We have great confidence it'll play out over time. Right now, it's a software solution that is really kind of just the beginning of a very long run. But if you know, maybe next time I can show the faces of the surgeons who come through here for a visit when they see kind of the tools that are provided through EOS Insight. It'd probably be the best reflection of enthusiasm around the platform. That's great. Thank you, guys.
Operator (participant)
Our next question comes from Matt Blackman with Stifel. Please go ahead.
Mathew Blackman (Analyst)
Good afternoon, everybody. Can you hear me okay?
Todd Koning (CFO)
Yes, we can, Matt.
Mathew Blackman (Analyst)
Yeah, great. So Todd, I wanted to go back to the 15% volume growth. So, if I'm hearing you correctly, it sounds like there was some dislocation as you sort of switched territories around. I guess, why is it manifesting now, versus maybe a couple of quarters ago? Maybe it has something to do with the timing of instrument set deployments. But how long does this persist? I mean, sales force dislocation can be tricky to work your way through. It does seem like, as I think about your guide, your updated guide for volume growth, that you've sort of baked it in for the remainder of the year. Is that how we should be thinking about it? Does it potentially bleed into 2025? And then I have one actual follow-up question.
Todd Koning (CFO)
Yeah, thank you for the question, 'cause I don't want to communicate that there is unexpected dislocation. This is a phenomenon where we added sales coverage, sales agents, in a territory where we have new surgeon interest. That surgeon interest is in our most distinct portfolio, which is really the lateral portfolio. And ultimately, we are upgrading that territory sales agency, ultimately, the existing sales agents, wind down. So that's the normal. They always wind down when the new guys wind up and come on. What was a little bit unexpected this time was the pace at which the existing guys wound their business down. Now, the reality is, the ASP of the business that has come on in that territory is lateral.
Caitlin Cronin (Analyst)
So, it's two XR average. That's a $15,000-$20,000 procedural price. What walked away was, you know, $3,000-$5,000 procedural price. And so, when we attract surgeons who are most interested in our most distinct portfolio, ultimately, you drive a higher level of revenue per procedure, and you always do expect the existing business to ramp down at some point in time. I would just tell you that it happened a little bit faster than we anticipated this quarter, and so that's the dynamic that went on. So, does that make sense?
Mathew Blackman (Analyst)
Yeah. No, it does. And does that persist? It does seem like you're baking it in for the remainder of the year with the updated guidance. Does that persist for a quarter or two quarters? Obviously, I would expect it improves, but, you know, when do you think you get back onto that sort of typical trajectory of whether it's surgeon productivity or rep productivity in terms of volume growth as opposed to ASP growth?
Todd Koning (CFO)
Yeah. So, I think at now, we're assuming essentially kinda high teens volume growth in the second half, which is really what we saw here. I guess we saw mid-teens in the second quarter. So, you're starting to see that tick up a little bit in the second half. So, we see a little bit of that recovery in the second half, Matt. So that's kinda how we see that playing out. And ultimately, the revenue per procedure that's implied in that Q3, the implication there is its kinda high single digits. Q4, it gets back to mid-single digits. So, I think that's how that effectively gets modeled in the remainder of the year between price and revenue per and volume.
Mathew Blackman (Analyst)
Got it. I guess the sort of counter to that would be, I mean, obviously, we're all thinking bigger picture here, particularly given the amount of investment in new distributors, new reps, in instrument sets, sort of hoping to see potentially some uptick in growth. Is the point, and maybe it comes, and maybe it doesn't, but maybe the point would be if we just look at, in particular, maybe we're not seeing it in the actual dollars yet here in the first and the second quarter of 2024, but we should be comforted by the fact that, you know, particularly here in the first half of the year, your surgeon training numbers are pretty substantial, and it...
Caitlin Cronin (Analyst)
And therefore, that's an indication that these reps are, in fact, bringing in new surgeons, and so, that is the real metric we should be sort of leaning on as we think about the outlook for growth from here. Is that fair?
Todd Koning (CFO)
I think that's, I think that's exactly the point, Matt. And, you know, as you look at that, I think the, the guide implies, probably a $2 million sequential step up, in our surgical revenue, I think. And, so, when you look at that, I think that reflects the underlying confidence that we have in, the growth of the business, looking forward.
Pat Miles (CEO)
Yeah, it's a nonlinear walk, and you know, I never thought that we'd be apologizing for 27% top line or surgical growth. But totally, totally understand your questions, but it is a put and take at every turn.
Mathew Blackman (Analyst)
Maybe I'm just gonna sneak in one more question. Apologies to everyone else here. But just on EOS, I guess the simple question is: Is EOS now at a point where it is a workhorse imaging system with all the enhancements, or is there something else, perhaps, that we're waiting for in the near-term pipeline that really sort of moves this to, again, a workhorse imaging system that a physician can use across, you know, 70% of their procedures?
Pat Miles (CEO)
Yeah, I would say it's a workhorse imaging system that has no competitor. You know, the problematic dynamic of imaging is that it is profoundly inconsistent with different magnification. It's imprecise, and just the ability to have a standard image out of EOS provides for opportunity of grand scale. It's I cannot communicate my enthusiasm more with regard to how we translate that image into an informatic tool that improves surgical care. We're well down the way of identifying a diagnostic platform, whereby what we can do is pull in different tools, again, to drive more clarity with regard to what patients require, what surgery, informed by a set of data that's derived in an automated way.
Caitlin Cronin (Analyst)
It's like, these are things that have evaded spine in the 30 years I've been part of it. And so to be able to be part of this and to support the architecture of it through the many luminary surgeons who have kinda advised us is phenomenal. So, again, the proof's in the pudding, and we're gonna be around to show the pudding. It, it's an exciting time.
David Saxon (Analyst)
All right. Thanks, Pat. Apologies for the more than one question, Tina.
Pat Miles (CEO)
No issue.
Operator (participant)
All right. Our next question comes from Drew Ranieri from Morgan Stanley. Please go ahead.
Drew Ranieri (Analyst)
Hi, thanks for taking the questions. Just maybe a couple from me that I'll ask together. So, Todd, I think you called out some supply constraints that you've maybe now resolved in biologics and expendables. Just curious if you can quantify maybe how much that might have cost you in revenue upside, potentially for the quarter? And I'll just ask my second here as well, but we've been getting more investor inbound, just kinda questioning the overall utilization environment, specifically when it comes to orthopedic and spine names.
Caitlin Cronin (Analyst)
So I mean, you're with, with 5-6% market share in the U.S., Pat or, or Todd, and/or Todd, just hoping to get your perspective of, on maybe what you're seeing in the market, and maybe what you're seeing specifically for, for surgeons that you have longer established relationships with. Thanks for taking the questions.
Todd Koning (CFO)
I'll take the first one, maybe Pat can take the second on the utilization. So, Drew, relative to supply constraints, I did call out two items where we really outgrew our supply. Ultimately, that's now resolved. We're not gonna quantify all of that, but I suffice it to say, as we think about our sequential Q2 to Q3 in surgical revenue, I think our expectation would be to go from $130 million to $132 million sequentially. So, I think that should give you a sense for, you know, our level of confidence, going into the third quarter and kinda sizing up and quantifying the overall impact of the dynamics we saw in the second quarter.
Pat Miles (CEO)
With regard to utilization, there's really been like... It's always tough. Like, you know, we're a 6% market shareholder. We're a proxy for nothing. I always like to say just because it's like we don't have as wide of a visibility on the market per se, but I would say it's been pretty typical. And so, at least, kind of, what we've seen exiting Q1 and through Q2, it's been a relatively typical time.
Operator (participant)
Okay. We'll go to the next caller, Brooks O'Neill with Lake Street Capital Markets. Please go ahead.
Speaker 10
Hey, guys, this is Aaron on the line for Brooks. Thanks for taking the questions. I was wondering if you could just give us an update on Japan and maybe how you're thinking about that market timing-wise. You know, I appreciate any existing penetration in Australia and New Zealand, but if you just could have any specific time horizons that you're thinking about, either in the short or long term. Thank you.
Pat Miles (CEO)
Yeah, super excited about Japan. A lot of the regulatory stuff is coming through. We hope to, like, you know, at least say, "Hey, we've done a surgery in Japan in the fourth quarter." And so, if so, much of, I think who we are as an organization is making commitments on timetables, and that was a commitment that we made, and we said, you know, Q3 to Q4 of 2024 for our first experience, and I like our chances. And so, that will be a market that we're gonna expect a lot out of over a long period of time. We're gonna give it the necessary tools and time to create the very market that we expect out of Japan.
Caitlin Cronin (Analyst)
So, anyway, super excited about Japan.
Speaker 10
Great. Appreciate it, Pat. Thank you.
Pat Miles (CEO)
Thanks.
Operator (participant)
All right, our next caller is David Saxon with Needham. Please go ahead.
David Saxon (Analyst)
Great. Good afternoon, Pat and Todd. Thanks for taking my questions. Todd, I just wanted to follow up on the free cash flow guidance change. So, what specifically is causing the DSOs to go up? How confident are you that the DSOs and inventory dynamics won't get worse? And I guess, do you still have confidence in the 2025 break-even target? And I have just one quick follow-up.
Todd Koning (CFO)
Thanks, David. On the DSO, I would say they just have not improved to the extent that we expected them to. So we were, I think, 40, like mid- to high 40s exiting last year, stepped up significantly in Q1, and I think that also had to do with some customer dynamics out there. I think there were some cybersecurity items that had hit different customers that delayed payments. Ultimately, we saw a significant improvement from, or we saw an improvement from Q1 to Q2, and we just have not seen as much of it. And so I think some of that may be also associated with just some of our general customer mix in terms of where we're growing.
Caitlin Cronin (Analyst)
So, my expectation is that we're not going to improve to where we've been exiting last year. And so fundamentally, we saw a step up Q4 to Q1. We stepped down Q1 to Q2, just not as much as I expected to, and so I'm expecting no further improvement on that front. On the DI or on the inventory, the DOH, you know, rank, we're at about four - a little over 400 here in the second quarter. Ultimately, as we're growing, I think this has been a dynamic of just how efficient, how much needs to go to each different sales agent as they ramp up. And so, I think as we've looked at it, we're assuming no further improvements.
We're putting a lot of effort and energy in the organization to get better at that and to improve it. I'm just, I'm just assuming that we don't, we don't see those improvements. And so, it's really, we did not see the improvements that we expected to see through our activities in the first half of the year, so I'm assuming that we don't see them in the second half of the year. And then your-
David Saxon (Analyst)
Okay, got it.
Todd Koning (CFO)
Your follow-up.
David Saxon (Analyst)
Yeah.
Todd Koning (CFO)
Your follow-up to that-
David Saxon (Analyst)
Yeah. Yeah, become 25.
Todd Koning (CFO)
25, right? Yeah. So, you know, as I think as we've said before, the belief in the cash flow and the cash breakeven is a function of the belief in the top line growth. The top line growth creates the opportunity then for us to expand profitability. The expansion of the profitability ultimately funds and feeds our cash flow. And so, if you think that, well, we can look at consensus, that's about $125 million of growth next year. 35% of that, you get $45 million of Adjusted EBITDA on the year-over-year drop through. So, if we ended this year at 25.5 and you add 45, you get $70 million.
Caitlin Cronin (Analyst)
So, that would be $7 million to essentially invest in sets and inventory and what you need next year. And so ultimately, we've got a lot of Adjusted EBITDA that ultimately funds the working capital needs of the business in 2025. And so, my confidence in achieving cash flow is a function of my confidence in the top line growth, which is predicated on the surge in adoption that we're seeing and the strong competitive sales reps and hiring that we're seeing. My confidence in our ability to continue to expand profitability is founded in the fact that we've demonstrated it for the last, you know, 8 quarters, and it's happened in the way we expected it to.
And I know the walk forward is consistent with what we've—the way we've built the company. And so, that's the confidence that I have. And then, you know, also knowing that we have invested significantly this year in sets and inventory, you also get a bit of a tailwind next year in the higher utilization of those assets next year, meaning you don't have to buy as much to meet your revenue targets. So, ultimately, that's how I sit here and feel comfortable with 2025.
David Saxon (Analyst)
Okay, great. So, if I could just quickly summarize. So even if these dynamics don't improve, maybe they do, but even if they don't, you guys have confidence in the top line growth, and that'll drive profitability, which drives free cash flow. To break even next year, still looks achievable. And then, maybe just confirm that that was a good summary. And then my follow-up, you kind of walked into, the $70 million, you kind of talked through for 2025. I mean, should we kind of be thinking of that as, as, you know, late or early guidance, or, is that just a, an illustration? Thanks so much.
Todd Koning (CFO)
Well, yeah. So, I can confirm your understanding, and the math I walked through, I think is consistent with our long-range plan expectations. I think consensus is like $66 million based on those numbers. So, I feel like that's a reasonable place to be.
David Saxon (Analyst)
Okay. Great.
Todd Koning (CFO)
Well-
David Saxon (Analyst)
Thanks so much.
Todd Koning (CFO)
We're not giving guidance at this point, but I think the logic, and we've laid out the framework in the long-range plan, and you're applying that framework, so.
David Saxon (Analyst)
Yep. Okay, great. Thank you.
Operator (participant)
All right, our next question comes from Jason Wittes with Roth Capital Partners. Please go ahead.
Jason Wittes (Analyst)
Hi, thanks for taking the question. So, congratulations on the launch of EOS Insight. I assume that's gonna have a lot of relevance in deformity. And I'm curious kind of where your deformity business is right now, and, you know, what else should we expect from the launch? Are you? You think you're fully prepared to go after that segment as with the EOS Insight launch?
Todd Koning (CFO)
Yeah. It's kind of the strategic question. It's you know... One of the things that's very apparent is that alignment and measures are relevant in short segment as well as long segment surgery. Clearly, when you think of deformity, you think of long segment surgery. Our relevance there has been muted. You know, we've been just. I would tell you, somewhat, when you when you create a company that was broken from nothing to something, you go to the place that you know in essence, reflects the most immediate influence, and that was lateral surgery. And so our ability to apply lateral in relatively short segment surgery was kind of the kinda initial kickoff of the company. That's driven much of the growth.
Pat Miles (CEO)
... We've used that growth, in essence, to continue to expand the complexity of tools that ultimately accommodate the lateral approach, but also say, "Gosh, how do we become a relevant participant in deformity?" And candidly, there hasn't been a ton of innovation in deformity. And you know, the opportunity that we have in terms of bringing a relative innovation package to deformity is very apparent. And so I think that EOS as an entree into our adult deformity and subsequently our idiopathic deformity, and then early onset is such the right walk. And so right now we have kind of the automated alignment measures. Next year, Q2 2025, we're sprinting at a bone quality measure through the same image acquisition as the automated alignment measures.
Caitlin Cronin (Analyst)
So again, I think that these things give us a very relevant informatic package that will drive a relevance in deformity surgery.
Jason Wittes (Analyst)
In terms of just hardware in general, do you think you have a full offering to put out in the field at this point, or is it lacking in some places?
Pat Miles (CEO)
Yeah. I would say in terms of adult and idiopathic, I would say, we have a great offering. Really, we're in the very, very early phases of some of the small stature stuff.
Jason Wittes (Analyst)
So, what milestones should we be looking for, to see, you know, how you're progressing with deformity? Because it's obviously a pretty... It seems like it's gonna double the revenue opportunity for the company.
Pat Miles (CEO)
Yeah, I you know really you know what we've modeled is kind of the growth of the company requisite to the technological advancement of the field. So, I think that you know the route to $1 billion requires you know 20% or north growth, and I think that it's contemplated in that number.
Jason Wittes (Analyst)
So, I mean, is this sort of, you're just launching now? I assume this is a multi-year process to really start to see, you know, I guess, real numbers being starting to be posted there. So I know you've given, you know, you've kind of given 2 or 3 year out at this point, I guess it's a 2, about a 2.5-year out, year outlook. Does that have much deformity in it, or is that pretty much all prefaced on the current state of business?
Pat Miles (CEO)
Yeah, it has a growing reflection of deformity in it. But, this, you know, it, it's interesting, I think, that, that, if anybody questions our, long-term commitment to this field, I think, you know, EOS is a proxy for a long-term commitment. And I think that, that where spine surgery needs to go, it clearly needs to evolve. You know, the, the revision rates are, are clearly way too high. And so as we mitigate variables through informatic tools, it improves surgery, and it'll, it'll expand our footprint. And so what we've done is we've contemplated that through the growth profile of the company.
Caitlin Cronin (Analyst)
And so, this is a multi-year walk and a opportunity that is, again, unique to us because we've been willing to commit the effort, the resources, and the work to innovating in this space.
Jason Wittes (Analyst)
Great. I'll jump back in queue. Thanks a lot.
Operator (participant)
All right, our last question comes from Sean Lee with H.C. Wainwright. Please go ahead.
Sean Lee (Analyst)
Hey, good afternoon, guys, and thanks for taking my questions. I just have two quick ones. One for EOS Insight into moves towards deformity. Do you feel the company's goal is more towards getting involved with existing deformity surgeons, or more converting surgeons who don't do deformity yet into doing deformity surgery? And if it's the latter, have you seen any examples so far?
Pat Miles (CEO)
Yeah. I would say that we're early in the experience. Just in terms of the way that the spine community evolves, I think there's gonna be a focal assembly of surgeons who do the most complex of deformity surgery. And so I think that we're focusing on the young surgeons that are very technically and technology savvy that are coming out of deformity programs. And so I would tell you that that's a big part of our efforts and focus, as well as I think the kind of the historically famous deformity surgeons have always been hugely pro-EOS.
Caitlin Cronin (Analyst)
And candidly, they've been extraordinarily supportive of us acquiring it because they know that we're committed to evolving the information package. And so, I would say that my presumption is that what's gonna happen is there's just gonna be a narrowing of the volume of surgeons who ultimately take on the majority of the deformity, and those people will be extraordinarily relevant to our focus and efforts.
Sean Lee (Analyst)
I see. That's very helpful. My second question is on you. I think Todd mentioned that there was a supply shortage with one of your biologics. I was wondering whether that's just a one-off event, or do you see a trend of biologics becoming a more material contributors to your overall portfolio? Thanks. That's all, that's all my questions.
Todd Koning (CFO)
Thanks, Sean. I think, as you know, biologics has been an area of growth for us, really probably over the last, you know, certainly the last 12, maybe the last 18 months. And so, as we've continued to grow and drive a higher attach rate, we just outgrew our supply. And so, at the end of the day, it was a demand-created situation for us, which we've now, you know, addressed. And so, I wouldn't say that that's a trend per se, but clearly, biologics has been a big growth driver for us, over the last, certainly last 12 to 18 months.
Sean Lee (Analyst)
I see. Thanks for the clarification.
Operator (participant)
All right, I will now turn the call back over to Pat Miles for closing remarks.
Pat Miles (CEO)
Thanks, Danica. Greatly appreciate everybody's support, and I hope shared enthusiasm over the whole EOS Insight launch. It is a significant one, and one that we'll look back on with great pride. So, anyway, appreciate everybody's interest. Look forward to catching up. Thanks.
Operator (participant)
Ladies and gentlemen, that concludes today's call. Thank you all for joining. You may now disconnect.
