Thank you, Matt, and good morning to everyone. 2023 was a transformative year for Xtant Medical. It was the culmination of a multi-year turnaround effort in which we established what we believe is now a robust platform for future growth. Now, with the foundation of exceptional market access and a nationwide distribution network established, we have created a scalable business model that resulted in record revenue in 2023 and has generated positive EBITDA adjusted EBITDA for the last three consecutive quarters. For the fourth quarter of 2023, we generated revenue of $28.1 million, an increase of 84% year-over-year. We're seeing positive returns of our business by achieving annual revenue growth of more than 58% in 2023, with our full year revenue of $91.3 million coming in ahead of our guidance range. Our organic revenue growth for the fourth quarter of 2023 was 9%.
This excludes the contributions from our 2023 acquisitions and has adjusted for a reclassification of our GPO fees, as Scott will explain later. Full year fiscal 2023 adjusted organic growth was 17% over full year fiscal 2022. In summary, full year 2023 was transformative. As previously mentioned, we grew by over 58% with adjusted organic growth of 17%. In addition to our record revenues, we finished the year with three straight quarters of positive adjusted EBITDA. Secondly, we acquired three separate businesses. Third, operationally, we improved our clean room capacity by over 50%. Fourth, we dramatically improved our margins by 540 basis points through improved operational efficiencies and improved mix of product. And then lastly, we ended the year with an even stronger balance sheet, with greater availability through our revolver to help us fund our growth.
By driving solid execution of our key growth pillars, we have significantly enhanced our financial position, enabling us to take the next step in capturing greater share of the spine and orthobiologics market. At this time, I'll provide an overview of how we build a platform that gives us the confidence to execute sustainable long-term growth profiles. As a reminder, our four key growth pillars are focused on 1, new product introductions, 2, distribution network expansion and contract access, 3, adjacent market penetration, and 4, strategic acquisitions. Starting with new products, like every healthy, robust organization, we are continually innovating with a deep pipeline of new products. During the course of our turnaround, we expanded our biologics product offering from 2 product categories to 5, which helped enhance our profitability profile. These higher margin products comprise the synthetics, Viable Bone Matrix, and growth factor.
When added with our legacy demineralized bone graft and allograft products, we are gaining operating leverage while also building our presence in the $2.4 billion U.S. orthobiologics market. Additionally, on the hardware side, we have a number of exciting new opportunities. Through the Coflex acquisition, we not only added but continue to revive two product lines in the fast-growing ambulatory surgery centers and outpatient markets. This acquisition also provides a payer services component that deepens our longer-term market access capabilities. Through the Surgalign acquisition, we filled in a number of missing pieces to our fixation line. In addition, we acquired a dynamic international business that is leading the way in motion preservation spine systems. We will be looking to bring some of those systems to the U.S. domestic market.
Overall, the acquisition of Surgalign has dramatically changed our product offering, which is now comprised of about two-thirds biologics and one-third fixation and hardware, compared to where we were before, which was an 85-15% split of biologics to hardware. The next pillar is our expanding distribution network and contract access. Our platform offers access to more than 450 IDNs and every major GPO that covers approximately 90% of all beds in the U.S. In addition, our growing distribution network, which now includes more than 650 independent agents, was further expanded by the Coflex and Surgalign acquisitions. Our vast network is selling our product today across various ASCs, outpatient clinics, and hospitals, which has helped us become a strong national company.
Now, turning to our third pillar, leveraging adjacent markets, we continue to build a presence in other markets to drive OEM sales, enabling us to diversify and expand our revenue opportunities beyond our core spine market. We've gained traction within the foot and ankle, trauma, and orthopedic implant markets, and we remain focused on capitalizing within these various segments by leveraging our expanded capacity. Our final pillar focuses on achieving growth inorganically through targeted acquisitions. We are seeking to become the integrator of enabling technologies. We are targeting companies that are either undercapitalized or subscale today. As we have the prior Coflex and Surgalign acquisitions, our focus on acquisition targets is based upon three characteristics. First, capabilities. We are looking at companies or technologies that give us greater capabilities, particularly in the regenerative biologics.
Additionally, we'll look at businesses that help complete Xtant's offering in the spine fixation and motion preservation offerings. Second, capacity. Capacity targets that we can expand our longer-term biologics production demand. So as we get bigger, we're going to need more space and more capacity to do that. Third, cash flows. Businesses that are profitable or can become profitable through cost or margin synergies. We believe that making sound, targeted, and strategic acquisitions that fit within our stringent criteria will take us one step closer to achieving our long-term goals. Our unique platform and robust distribution network will provide future companies that we acquire the ability to take advantage of being part of a fast-growing company.
Furthermore, we believe it will allow the entrepreneurs and other owners of those companies the ability to win when they are purchased and then win even bigger over time as Xtant continues to grow, which we believe it will. As part of our strategy to meet increasingly strong demand and long-term profitability, we have dedicated our operational efforts to implementing crucial process improvement initiatives and expanding capacity. These measures have significantly increased both our production levels and overall efficiencies, enabling us to achieve scale in both product sales and deliveries. Furthermore, with the recent acquisition of the nanOss production operations from RTI Surgical announced in the fourth quarter of 2023, we are now better equipped to produce more of our own biologics in-house. Xtant is committed to driving long-term sustainable revenue growth and maximizing shareholder value.
To better support the fast pace of our growth initiatives, we are pleased to increase our revolving credit facility with MidCap Financial to $17 million from $8 million. Moreover, access to more capital positions us well to further execute on our strategy and capture greater market share within the orthobiologics market. Finally, we established our full year 2024 revenue range of $112 million-116 million. This guidance range represents annual revenue growth of approximately 23-27% compared to the full year 2023, and it includes contributions from the Surgalign transaction in addition to the strength of our organic business. We anticipate that our growth will accelerate faster starting in the second quarter of 2024 and even more so in the second half of 2024.
This is driven by a normalized supply environment in our stem cell business that was adversely affected by the temporary market shortage in the second half of 2023 and the first quarter of 2024, and revitalizing the Surgalign supply chain. More specifically, as Surgalign went through its financial troubles and eventual bankruptcy, important vendors naturally pulled back from producing products for fear of not getting paid. Some of those supply issues impacted our fourth quarter results, and we expect to continue to see some softness in key product areas such as Coflex and Surgalign for the first half of 2024. Moving forward, 2024 is focused on self-sustainability. Our goal is to be self-sustaining in our supply chain where we are less reliant on production outside our control. We believe this self-reliance will allow us to be a larger and more diverse producer of biologics.
Moreover, producing our own products should dramatically improve our margin profile, coupled with an expanded product line that brings additional transformative treatment options to a large and growing patient population. Most importantly, our progress in 2023 positions us well on a path to continue positive Adjusted EBITDA. Now, I'd like to turn the call over to Scott, who will discuss our fourth quarter and full year 2023 financial results.
Thank you, Sean, and good morning, everyone. Total revenue for the fourth quarter of 2023 was a record $28.1 million compared to $15.3 million for the same period in 2022. Our 84% annual increase is attributed primarily to greater independent agent sales, contributions from the Coflex and Cofix product lines, opportunistic private label sales, and product sales from the recently acquired Surgalign hardware and biologics business. During the fourth quarter of 2023, we reclassified all GPO fees incurred during the full year as offsets to revenue from their previous classification as SG&A expense. As a result, organic and total revenue growth rates for the fourth quarter of 2023 were downwardly impacted by approximately 800 and 1,000 basis points, respectively, with fourth quarter 2023 organic growth before the reclassification totally 9%, while organic growth as reported totaled 1% in each case over fourth quarter 2022 organic growth.
Gross margin for the fourth quarter of 2023 was 61% compared to 54.4% for the same period in 2022. The increase was primarily attributable to greater production efficiencies and favorable product mix, partially offset by higher product costs. Fourth quarter 2023 operating expenses were $20.9 million compared to $10 million in the same period a year ago. As a percentage of total revenue, operating expenses were 75% compared to 66% in the same period a year ago. General and administrative expenses were $8.9 million for the three months ended December 31st, 2023, compared to $4 million for the same period in 2022. This increase is primarily attributable to additional compensation expense, acquisition-related legal expenses, amortization of intangible assets associated with the Coflex and Cofix product lines, and higher consulting fees associated with acquisition-related activities.
Sales and marketing expenses were $11.6 million for the three months ended December 31st, 2023, compared to $5.8 million for the same period of 2022. This increase is primarily due to additional commission and compensation expense and higher professional service fees. Net loss for the fourth quarter of 2023 was $4.3 million or $0.03 per share, compared to a net loss of $2.2 million or $0.02 per share in the comparable 2022 period. Adjusted EBITDA for the fourth quarter of 2023 was $0.7 million compared to an adjusted EBITDA loss of $0.8 million for the same period in 2022. As of December 31st, 2023, we had $5.9 million of cash, cash equivalents, and restricted cash, $20.7 million in net accounts receivable, and $36.9 million of inventory.
As Sean mentioned earlier, in March, we increased our availability under our revolving credit facility to $17 million to help fuel our future growth. Operator, you may now open the line for questions.
Thank you. We will now be conducting a question-and-answer session. If you would like to ask a question, please press star one on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star two if you would like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. One moment, please, while we pull for your questions. Our first questions come from the line of Ryan Zimmerman with BTIG. Please proceed with your questions.
Good morning, and thanks for taking the questions, and congrats on all the progress, guys.
Thanks, Ryan.
I wanted to start on 2024 guidance, if you could. Appreciate the color you gave on seasonality. Appreciate some of your comments on the contributions. But can you expand a little bit more, Sean and Scott, just on how you think about the breakdown of the legacy business versus some of the contributions from the Surgalign business, and maybe expand a little bit on what you think the growth drivers are for 2024? And again, appreciating that the stem cell dynamics kind of come into play beginning in the second quarter.
Okay. I'll jump in first, and Scott, I'll let you add any color to it. So Ryan, to be when we think about the contributions of Surgalign, first of all, we had great contributions in the fourth quarter from both the Surgalign domestic business as well as the international business. But as I mentioned, one of the problems we're having is the supply chain of they were basically selling things right off the shelf. So we're catching up in getting those supply chains and those suppliers to start filling up our inventories again, which is a good problem to have in way of the demand is there, and it's growing.
So when I think about for instance, you asked one of the questions is, "Where do we see growth coming from Surgalign in the next year?" We released a brand new product line called Cortera, which has really taken off and done very well. Matter of fact, one of the first things we did is we added more sets to that product line, and quite frankly, we probably were short on it. We actually should have gone longer than we did. And so we're going to get some nice growth from that. That'll really be coming in the second half of the year from Surgalign's perspective. Another big area for us will be some of the OEM production that we'll be doing specifically on the OEM or I mean, on the amnio side, and then some of the other base core biologic stuff.
We got a new fiber product that's going to be coming out this year. You're going to see a fair amount of things that just from a stem cell perspective, we are now in a position where finally we've got enough product on hand where we can actually start meeting the demands. And we've never, ever been in a position like this. So as we look at the second quarter, we'll start to see a nice pickup with respect to our stem cells. And then just with our overall OEM and other production that's going to take place in the second half of this year, we expect to see things really start to take off both in our own biologics production as well as in what we'll see from the Surgalign hardware side.
Okay. That's very helpful. And Scott, you alluded to a couple of opportunistic OEM orders, I think, in the fourth quarter. Talk to me about the environment here, what you think you can do with that business. Wondering, just given our coverage of some of the other companies that are struggling in these areas, I'm curious if there's a read-through here that you're able to capitalize on maybe some other companies that may be struggling there just on the OEM side. And then I have a couple of follow-ups.
Yeah. I think early on in the year, we won't necessarily see the contribution we did in Q4 or even Q1 of last year on the OEM side. I do think there is a particular opportunity there in the back half of the year, both on legacy products but also in way of new production, both in stem cell and amnio. So we look forward to that. But we do expect to be quieter on that front at the initial part of the year.
Okay. Very helpful. And then gross margins have been really nice to see. They've come in a little bit over the past three quarters but still hovering over the 61% level. Do you expect that to continue in 2024, and kind of where do you think you can take those gross margins as we get the stem cells back online?
Yeah. I think our gross margins really trend with the stem cells and also the source of those. Where we see that coming in from an internal standpoint, that'll be a significant driver of gross margin improvement. And then as we also add a little more mix in way of hardware, that should also bump up margins as well. But I think as the product mix goes, so too will gross margin, and we'll look for that to improve throughout the course of the year.
Okay. Thanks for taking my questions, guys. Appreciate it. Those are good answers. Thank you.
Thanks, Ryan.
Thank you. Our next questions come from the line of Chase Knickerbocker with Craig-Hallum. Please proceed with your questions.
Good morning, guys. Congrats on the good finish to the year here. Maybe starting on a couple of financial ones for Scott. GA looked like it was a bit elevated as a percentage of sales in Q4. Can you just kind of walk me through what might have been in that in Q4 and kind of the right way to think about it as a percentage of sales, how it kind of trends through 2024?
Yeah. I think there's probably three main drivers you're seeing there, Chase. The first being acquisition-related expenses, which you'll see broken out in the Adjusted EBITDA table. The second piece of that is going to be commissions. And then third, I think we ran a little high just for certain compensation components that should back off or become more normalized going forward. So as a percentage of revenue, I expect that to come back down. But those are really the three main drivers of it.
Got it. Thanks. And then maybe on 2024 guidance. And it looks like it assumes something in kind of the mid-single-digit range for an organic growth rate perspective. I appreciate those comments that you gave kind of on those two dynamics. But should I think of this as building in quite a bit of conservatism if we're looking at something in the mid-single-digit range from an organic growth perspective, or should I think about your business swelling from an organic perspective in 2024?
As I would jump in on this one, is that yes, there's a fair amount of conservatism just because there's some unknowns, right? But we feel very good that there's a significant upside. So yes, there's some conservative pieces to this. We do think that eventually, we can get to double-digit on the organic side of things. It's just going to be in the second half of the year.
Got it. I just kind of want to pick up on some of the stem cell trends that you kind of talked about a little bit in the previous Q&A. It sounds like you guys are kind of not supply-constrained there as far as kind of inventory goes at the moment. Kind of when did that inventory kind of improve? And is that something you expect to kind of continue through the year and your conversations with your suppliers?
Literally last week is when it improved. So yeah. So with one of our main suppliers, the main supplier for whom we work with, we had started providing donors that they could start processing, which was new. And that started in the beginning part of this year. And so those donors have now just recently been cleared. We had some very high-yielding donors with yeah. So we're very flush, and we plan to be flush with inventory throughout the year of this. And so within literally the last days of the quarter, we had the inventory that we can now start to sell. So our guys are really starting to gin up what was the demand we previously had and then, of course, demand that we've had to walk away from over the course of the last few years.
I mean, it seems like it's kind of a supply-constrained kind of market at the moment. Do you expect that to get filled pretty shortly, or do you think there is kind of some chasing down of volume that you need to do? And then second, as it relates to that kind of trend with the stem cell business, should we think of gross margins kind of showing improvement year-over-year, not quite as much as in 2023, but still meaningful kind of year-over-year improvement kind of as you have a more favorable product mix?
Yeah. So here's what I'd say, is that the initial demand is still really very tight. This is actually part of why for us, providing donors to our supplier was a big part of it, right? So that's one of the things that at least helped us get out. But many of the guys that are out there today who were once selling this are still struggling to get enough product out there. So there is still some supply constraints. We just happen to be in a much better position than we were, even, gosh, three months ago, never mind the last half of 2024. And then when we think about margins for that product line specifically, the margins for this product line, because we are supplying donors, is going to be a little bit tighter in the first half of the year.
But in the second half of the year, it'll get substantially better.
Thanks. Maybe just last, kind of the Coflex update, kind of talk about how that product did in Q4 and kind of steps you're taking to kind of improve reimbursement and kind of the updates there?
Sure. Yeah. So really pleased with where that business is today. Again, this was a complete revival project. This was one that the focus that we've put towards both the clinical and the reimbursement side, this is just something, quite frankly, from Surgalign's perspective, there's so much going on that this was really a hard thing to focus on. And so we have done that. And so I'm really excited about what we've been able to at least stabilize the business. And now we're starting to win some new plans. We just got coverage for a great regional plan in New York that gives us basically almost full coverage in New York. So having the fourth-largest state in the union fully covered, this is really kind of a nice milestone for us.
So we believe that we've seen the bottom with that business, and we believe that we're now going to be starting to grow it. And so we're really kind of excited about where the prospects for that business, especially because it is such a great technology. I think everybody on this call, if I just rationally explain to you the beauty of what Coflex does in way of motion preservation and just, again, what it does for people clinically or therapeutically, it's just a great product. So we're really excited about its prospects.
Got it. And last one, I'm going to hop back into queue. Sorry, guys. Scott, just kind of good sequential improvement in Adjusted EBITDA, that margin starting to take up. I mean, just kind of speak to your confidence in 2024 continuing to improve that Adjusted EBITDA margin even despite some of these kind of internal investments you guys are making.
Yeah. I think it gets back to Sean's initial comment as it relates to our product offering. I think all of those things, in addition to the improvements we've made in way of yield improvements and scrap reduction, etc., will all provide nice sequential improvements to gross margin both during the course of 2024 and beyond. So we feel really good about that.
Great. Thanks, guys.
Thank you. At this time, we have no more questions. I'll turn the call back over to Sean Browne for any closing remarks.
Thank you, operator. Overall, I'm very pleased with the progress we have achieved in 2023. In short, we almost doubled our revenue with both strong organic growth and the assistance of three newly acquired businesses. We dramatically improved our margin by over 540 basis points, resulting in positive adjusted EBITDA for three consecutive quarters. Our efforts in expanding our capacity and distributor network have allowed us to meet the increasing demand for our biologics and fixation products, enabling scalability. We are enthusiastic about leveraging this momentum to further our overarching goal of maximizing shareholder value. We have laid revenue growth guidance of between 23% and 27% for full year 2024, driven by Xtant taking over the supply chain for both internally produced products and improved vendor management of the acquired Surgalign products.
We see solid growth in the first half of the year with increasing velocity as we produce more of our own goods in the second half of this year. In closing, I want to reiterate our mission of honoring the gift of donation by allowing our patients to live as full and complete a life as possible. I appreciate the dedication of our valuable employees. Without them, our success and achievements would not be possible. Thank you for joining us today and for your continued support.
Thank you. That does conclude our call. All parties may now disconnect. Enjoy the rest of your day.
