Michael Cordonnier: Thank you, Stephanie, and welcome to the team. I would like to welcome everyone on our call today. At Carlsmed, our mission is to improve outcomes and decrease the cost of health care for spine surgery and beyond. To achieve this mission, we have pioneered patient-specific digital surgery for lumbar and cervical spine fusion procedures. Our vision is to make personalized surgery at scale the standard of care for spine surgery. Our AI-enabled digital surgery platform empowers surgeons to partner closely with patients to seamlessly create 3-dimensional surgical plans and 3D-printed spine fusion devices designed to achieve predictable patient outcomes while supporting the surgeon's preferred surgical approach. We then provide postoperative outcome analytics to our surgeon users for each procedure through our aprevo insights as part of the myaprevo ecosystem. We believe this personalized outcome-driven AI-enabled ecosystem approach represents the future standard in medical technology, one that is better for patients, surgeons, hospitals and payers. Importantly, our model is built to scale efficiently. By manufacturing only what is needed for each specific procedure, we avoid the traditional prebuilt inventory trays of implants and instruments that have long burdened the legacy spine and orthopedics businesses. Instead, we're able to provide patient-specific, sterile-packed implants and instruments specific to each patient just in time for their surgery. This capital-light demand-driven approach enables us to scale rapidly while maintaining a relentless focus on patient outcomes. With this vision as our guide, 2026 is off to a great start with solid execution across our business. In the first quarter, we saw strong adoption of our lumbar and cervical personalized surgery procedures, reinforcing our view that aprevo as a platform technology is positioned to transform spine surgery. Our clinical outcome data continues to be robust, and our investments in technology continue to drive the scale and productivity needed to make personalized surgery the standard of care for spine fusion procedures. With the peer-reviewed data published on reduced reoperations with aprevo personalized surgery procedures, we continue to execute on our mission to improve outcomes and decrease the cost of health care for spine surgery. Turning to the first quarter. We delivered strong revenue of $16.1 million, representing growth of 58% over the prior year. Our growth was driven by the continued focus on medical education and compelling clinical outcome data, driving expansion of our surgeon base and increasing procedure volumes. Operationally, we continue to leverage our investments in technology to further drive production efficiencies, reducing lead time by more than 30% to 6 business days in the quarter and delivering more than 200 basis points of margin expansion year-over-year. Our fully integrated digital production system allows us to partner with hospitals, surgeons and patients to seamlessly integrate into clinic and operating room workflows preoperatively intraoperatively and postoperatively for nearly all indicated patients. Our commercial growth continues to be driven by a surgeon-led adoption model and expanding utilization. I'm proud to report that we grew our total surgeon user base by more than 60% year-over-year, reflective of the rapid clinical adoption of personalized surgery procedures. We continue to drive particularly strong engagement from early career and post-fellowship surgeons who are eager to adopt new technology to differentiate their practices and improve outcomes. With our rapidly growing base of surgeon users, we're still in the early innings of market penetration and have a long runway ahead of us. The aprevo lumbar procedure represents the majority of our business today, where we continue to gain traction within the estimated 445,000 lumbar spine fusion procedures performed annually in the U.S. Clinical evidence generation continues to support the early adoption of aprevo by consistently demonstrating improved outcomes for patients compared to stock implants. In January, data published in the Global Spine Journal further validated our personalized spine surgery approach, including evidence demonstrating a 74% reduction in surgery revision rates at 2 years compared to stock devices. This peer-reviewed study compared 2-year revision rates among complex adult spinal deformity patients receiving Carlsmed's aprevo personalized interbody implants with previously published revision data from a similar patient cohort receiving conventional stock implants. Patients treated with aprevo experienced significantly fewer revisions due to mechanical complications, showing a revision rate of 4.3% in patients treated with aprevo compared to a revision rate of 16.6% of patients who had stock devices. To put this into perspective, over the past 25 years, lumbar fusion technologies have not published data to demonstrate significant reduction in reoperation rates at the standard 2-year benchmark. In contrast, aprevo patient-specific lumbar procedures have demonstrated clinically meaningful reduction in reoperations, driven by significant decreases in key complications like rod fractures and proximal junction kyphosis. Importantly, this improvement is measured against procedures with traditional stock fusion devices used by the most experienced and skilled surgeons. As a further expansion of our aprevo lumbar procedure, we have announced successful completion of the first aprevo bilateral lumbar fusion procedure in February. We are seeing great data in our limited market evaluation and are on track for our full commercial launch in the fourth quarter of this year. Carlsmed's aprevo lumbar fusion technology has strong hospital reimbursement from CMS with all aprevo lumbar fusion procedures covered by 1 of 11 different MS-DRG codes. The majority of aprevo lumbar procedures are reassigned to the 3 elevated major complication or comorbidity MS-DRG codes. This provides hospitals with superior economic and clinical value to provide access to the aprevo procedure for patients. On April 10, CMS published the FY '27 proposed rule for inpatient prospective payment system. Under this proposed rule, all aprevo lumbar spine fusion procedures would be reimbursed by 1 of 3 new MS-DRG codes. 523, 524 or 525 at a premium to traditional spine fusion procedures. If finalized as proposed, we see this development as very positive for patients, surgeons and hospitals to establish and maintain long-term access to the aprevo lumbar spine fusion procedure. This published rule is preliminary. We anticipate the final rule to be published prior to becoming effective on October 1, 2026. Shifting to cervical. The first quarter 2026 represented our first full quarter in market commercially with the aprevo cervical fusion procedure, which we launched in December of 2025. With an estimated 370,000 cervical fusion procedures performed annually in the U.S., we believe that this additional growth lever can provide additional momentum in our business as a further extension of the aprevo platform. Cervical and lumbar spine fusion procedures are performed by spine surgery trained neurosurgeons and orthopedic surgeons alike. Many of the spine surgeons perform both lumbar spine fusion and cervical spine fusion procedures, demonstrating a substantial procedural overlap across spine surgeons. We believe that we can leverage our team to train and onboard many of the surgeons already familiar with the lumbar aprevo technology platform on the aprevo cervical platform. In the early days of launch, we have already trained more than 20% of our surgeon users on the cervical platform. The aprevo cervical procedure is designed to address common causes of variable outcomes associated with anterior cervical discectomy and fusion, ACDF failure, including subsidence, malalignment and reoperations. The procedure is designed to optimize bone contact surface area to improve load distribution, bone graft loading, preserve endplate strength, reduce subsidence risk and restore or maintain alignment. To complement aprevo cervical and achieve progress against some of these challenges in cervical fusions, our newly announced corra cervical plating system marks the debut of Carlsmed's patient-specific fixation portfolio and represents a fully personalized solution for ACDF procedures. The first procedure was performed in February 2026 at the University of California, San Francisco. We are progressing well with the limited market evaluation and are on track for the launch of corra cervical personalized plating system in Q4. Much like the lumbar aprevo procedure, the cervical aprevo procedure has a strong inpatient reimbursement profile. In October 2025, the aprevo cervical procedure received a new technology add-on payment up to an incremental $21,125 hospital reimbursement. This reimbursement program is for a 3-year period and CMS renewed the NTAP payment for FY '27 as anticipated in the publication of the preliminary rule. Looking ahead, our strategic focus remains consistent and positions us to continue the durable, high-quality growth we've demonstrated to date. Within our first area of focus, patient-centric innovation, we continue to advance our proprietary personalized surgery platform, including AI-enabled 3D surgical planning, workflow automation, patient and surgeon-specific devices and single-use sterile pack surgical instruments and further procedural integration in the clinic and operating room. As discussed previously, we have demonstrated great early traction with the recent launch of aprevo Cervical, and we're collecting early clinical experience with the bilateral posterior aprevo procedure and personalized corra cervical plate fixation. Our product innovation portfolio includes further advancements to drive ease of integration in the surgical workflow and further personalization of spine surgery. Our second area of strategic focus is surgeon education and includes further investments in our medical education team and programs to meet accelerating demand for aprevo personalized surgery. We continue training new surgeons every month by leveraging success in academic centers to drive peer-to-peer surgeon education with the thought leaders in personalized spine surgery. We also continue to support education initiatives with upcoming resident and fellow courses in partnership with leading academic institutions. As previously mentioned, we have seen strong uptake with early and mid-career surgeons that are adopting digital surgical planning into their practice in their efforts to streamline workflow and improve patient outcomes. These surgeon users will continue to shape the future of spine surgery, and this is an ongoing growth driver for Carlsmed that we believe will continue to drive adoption and utilization. Our third area of strategic focus, commercial execution continues to center on surgeon onboarding, increasing surgeon utilization and expanding access within hospital systems. As we continue to scale, we've expanded our strategic and national accounts efforts to enable local and national access across large hospital systems. Across both lumbar and cervical platforms, hospitals are recognizing the clinical workflow benefits enabled by the aprevo ecosystem. By providing deeper integration within a surgeon's preoperative and postoperative clinical workflow, we believe that our platform solution can simplify the surgeon's pre-op planning, reduce time and complexity of the spine fusion procedure in the OR and enhance surgeon's ability to provide predictable outcomes to spine fusion patients. Lastly, we will continue to generate clinical data to support medical education and market adoption of our transformative personalized surgery technology platform. We believe that personalized surgery at scale is a new standard of care for spine fusion and are committed to providing solutions to patients, surgeons, and hospitals that reduce revision surgeries, improve outcomes and reduce the cost of health care. We're just getting started and look forward to providing further updates on our rapid market adoption. With that, I'll turn it over to Leo, who will review our financial performance.
Leonard Greenstein: Thank you, Mike, and good afternoon, everyone. I'll begin today with first quarter 2026 P&L highlights. Revenue for the first quarter of 2026 was $16.1 million compared to $10.2 million in Q1 2025, representing 58% growth year-over-year. This growth was driven by the continued expansion of our total surgeon user base and increased unit volume sales of aprevo as our average revenue per procedure remained substantially consistent between periods. Gross margins were 77.1% in the first quarter of 2026 compared to 74.9% in the first quarter of 2025. This 220 basis point increase was driven by our stable average revenue per aprevo procedure, combined with efficiency improvements in our digital production system with investments made over the past few quarters. This now allows us to deliver the aprevo kit to the operating room within 6 business days of surgeon approval of the digital surgical plan. This lead time and the associated production capacity it enables will support our continued scale. Total operating expenses were $21.7 million in the first quarter of 2026 compared to $13.4 million in the first quarter of 2025. Of this amount, R&D expenses were $5.2 million this quarter compared with $3.2 million in Q1 2025. This increase was primarily due to higher personnel costs to advance our patient-centric product development priorities and AI-enabled initiatives for our digital surgical planning processes. Sales and marketing expenses were $10.3 million this quarter compared with $6.7 million in Q1 2025. This was substantially driven by increased sales headcount to drive our commercial execution strategy and variable commissions to our sales team and independent sales agents with our revenue growth as well as increased marketing spend. General and administrative expenses were $6.2 million this quarter compared with $3.5 million in Q1 2025. The increase was driven by personnel additions and professional services costs and legal fees for customary corporate and intellectual property matters as well as compliance and other public company-related costs. Our GAAP net loss was $8.7 million this quarter compared to net loss of $5.7 million in the first quarter of 2025. EBITDA adjusted for stock-based compensation was a negative $7.5 million this quarter compared to a negative $5.5 million during the first quarter of 2025. We anticipate continued improvement in adjusted EBITDA over the coming years, driven by expected revenue growth and leverage across our expense base. As we scale, expanding contribution margin dollars enabled by our capital-light digital-first business model provide a clearly modeled pathway towards cash flow breakeven. Moving to our balance sheet. Our cash and investments as of March 31, 2026, totaled $97.1 million. The outstanding principal under our $50 million debt facility remains at $15.6 million. While we have no current plans to make additional draws ahead of its October 2030 maturity, this facility provides low-cost, non-dilutive standby capital and supports general corporate flexibility. Total liabilities as of March 31, 2026, were $26.5 million, of which $15.6 million relates to this debt facility. Our cash used in operating activities was $13 million during the quarter compared to $8.2 million in the first quarter of 2025. Unlike traditional MedTech businesses that require capital investments in stock implant and instrument sets, our business scales without these barriers to profitability. As a pure-play personalized surgery company, our working capital could be more strategically deployed towards continued commercial investments to drive significant growth, delivery of our operational excellence priorities in digital production and continued R&D pipeline development for our business value and growth. Turning to guidance. We are raising our full year 2026 revenue range to be between $72 million and $77 million in revenue, representing 48% growth at the midpoint over full year 2025. As we progress towards profitability, we continue to expect gross margins to remain in the mid- to high 70s and anticipate driving operating expense leverage in the coming quarters with expected revenue ramp in aprevo lumbar and cervical. With that, I'll turn the call over to the operator for questions.
Operator: [Operator Instructions] Our first question comes from David Roman of Goldman Sachs.
David Roman: I wanted just to start a little bit on what you're seeing from a surgeon utilization perspective. We did see strong surgeon adds exiting 2025. Can you maybe give us some perspective on how -- what you're seeing year-to-date qualitatively? And then how you're seeing utilization across both new and existing surgeons trend in the quarter and how you're thinking about the balance of the year?
Michael Cordonnier: Feel really good about our surgeon enthusiasm for the aprevo platform. And as we exited Q4 with a really strong new surgeon adds, we saw that continue to accelerate into the year. And as we discussed in the call, year-over-year, we've added about 60% increase to our surgeon users. With that, we continue to see ongoing increase in utilization, particularly those surgeon users that have gone through the initial trial process and continue through that adoption. So with that, we're really -- feel really good about the utilization and surgeon user adds that we've had.
David Roman: Got it. Got it. And then I think, Leo, in your prepared remarks, you mentioned that average selling prices for aprevo were roughly flat year-over-year. If I remember correctly, cervical procedures do come with lower ASP than lumbar. So can you maybe corroborate that point? And then is it just that cervical isn't big enough as a percentage of total to move average ASPs? And how should we think about the weighted average selling price as cervical becomes a larger percentage of total going forward?
Leonard Greenstein: Yes, David, this is Leo. So our Q1 average revenue per procedures were consistent over the prior year quarter in Q4 as well as Q1. So as we think about the future here and the combination of cervical and lumbar, we're projecting our average revenue per procedure to be in the mid- to high 20s as cervical takes a greater proportion of revenue over time. And the average revenue per procedure for cervical is less than lumbar. So to answer your question directly, though the contribution margin and the ability for us to further scale our business on a single aprevo platform that serves both the lumbar and cervical indications with largely the same call point provides the operating leverage in our business to continue to scale and do so efficiently.
Operator: Our next question comes from Travis Steed from Bank of America.
Unknown Analyst: This is [ Aidan ] on for Travis. So first full quarter of the cervical launch, can you talk about the puts and takes and how that's progressing? I think you said 20% of your surgeon users are now trained on that. What are you seeing from those accounts that have been trained so far? And then are we still expecting kind of high single-digit, low double-digit revenue contribution from cervical for the year? And I have a follow-up.
Michael Cordonnier: Yes, we feel really good about the traction that cervical has received here in the first quarter of launch. And as we -- as reported, as you mentioned, about 20% of our total lumbar users are now trained on cervical and going through the ramp. As we see this progression, high single-digit, low double-digit percent contribution of revenue from cervical in the total plan for the company looks about right.
Unknown Analyst: Great. And then in the Q, I did call out cost improvements and production fees charged by your contract manufacturer. Can you double-click on that and talk about if that's a onetime? Or is this something we can expect to continue going forward?
Leonard Greenstein: Yes. We've made investments in our digital production system holistically that's allowed us to hit that 6-day lead time. That really provided efficiencies in our production process, inclusive of those with our contract manufacturer. But the investments made in those earlier quarters going back to Q3 of 2025 now allow us to cut out cost and time importantly out of the system. So what we are currently reporting in that high 70s gross margin, we see to be sustainable.
Operator: [Operator Instructions] Our next question comes from Richard Newitter from Truist Securities.
Richard Newitter: Congrats on the quarter. I wanted to just go to the CMS proposal that just came out. I think you had mentioned the premium and also broader coverage. I think in the past -- and those are 2 things that I think could be pretty significant tailwinds for you in 2027, assuming everything goes as proposed into the final rule. So I guess just on what percentage would you say of your procedures currently are generally getting reimbursed and covered consistently? And kind of how much would this broaden that coverage swath, if you will? And then just on the premium, I think we did some calculations, and we're estimating it could be an incremental $50,000 reimbursement for stock implants on average. Obviously, there's a big range in there. I think that's somewhere around $25,000 to $30,000 on average today above and beyond or the premium to your traditional stock implants. Is that ballpark kind of the math that you guys have worked out?
Michael Cordonnier: Rich, thanks for the questions. I kind of talk about this in 2 parts. First, the current state of reimbursement for the aprevo lumbar platform. As reported in the script, we currently have 11 different MS-DRGs that cover the aprevo lumbar platform, all with existing coverage and reimbursement. As noted, a portion of those elevate to a higher-paying DRG today. With the proposed IPPS rule, it really simplifies the coding and reimbursement that all aprevo procedures would map to 1 of 3 different MS-DRGs. And based on your calculations, that seems about how it would look on a national average. And so we agree. We think this is a really great solution that CMS is proposing to give significant reimbursement to these procedures.
Richard Newitter: That's great. And then just what could it do in terms of the -- where you're potentially meeting resistance or there's just not great coverage currently? What could this do for you from that standpoint? Is it 50% currently? Is it 80%? Like just give us a sense as to how this could broaden your coverage and access.
Michael Cordonnier: Yes. We really look at this as access versus coverage because we have full coverage today where we really think this will provide value to hospitals, in particular, is to remove the ambiguity and actually simplify coding for the aprevo procedure. And so we see this as very beneficial to the hospitals to simplify the process so that they can code procedures as they normally would and know that they'll map the right MS-DRG.
Richard Newitter: Okay. That's really helpful. If I could squeeze one more in. Just following up to David's question earlier. As cervical increases as a percentage of the mix moving through the year, just Leo, how should we think of the gross margin impact if revenue per procedure gets impacted the gross margin, too, I would imagine. So just if you could give us anything on the cadence as we move through '26 that you'd want to call out 2Q to 4Q?
Leonard Greenstein: Yes. So as we mentioned during our prepared remarks earlier, we see gross margins being in the mid- to high 70s over the coming quarters. That factors in, as Mike covered earlier, a high single-digit, low double-digit mix between lumbar and cervical. So the headwinds with the lower gross margin profile of cervical, notwithstanding the tremendous contribution margin it provides and the leverage it provides in our business is going to be offset as we see it with our efficiencies in digital production for lumbar.
Operator: Our last question comes from Ryan Zimmerman from BTIG.
Iseult McMahon: This is Izzy, on for Ryan. Mike, I heard your comments and all the discussion around the IPPS proposal for 2027. I was just curious what you have heard in terms of feedback from your hospital customers and surgeons in reaction to the proposal? And do you -- I know it's going to simplify coverage, but do you expect that there could be some benefit in terms of volumes if it's proposed as written?
Michael Cordonnier: Thanks for the question. It's early days, and it is preliminary rule. And so we're really holding off on those discussions until the final rule goes into place. However, this is something that, as mentioned, simplifies coding, simplifies reimbursement and makes a permanent change to the aprevo procedure at a higher reimbursement level. So net-net, we think this is better for all stakeholders.
Iseult McMahon: Appreciate it. And then, Leo, I've heard your commentary on guidance. But as we consider contribution layering in the back half of the year from those new product launches, is there anything that we need to keep in mind in terms of phasing on the top line?
Leonard Greenstein: Yes. Look, we see over -- in the coming quarters, aprevo lumbar to carry the majority of our revenue and overall contribution. Certainly, we're very pleased with the early days here of cervical and the clinical results our surgeons are seeing with that indication, how neatly it tucks into the aprevo platform and ecosystem. We'll provide additional color as we progress in the quarter -- in the subsequent quarters with how we see additional things shaping up for the company's favor to further drive revenue beyond what we previously guided.
Operator: This concludes the question-and-answer session. Thank you for your participation in today's conference. This does conclude the program. And you may now disconnect.
