Good afternoon, and welcome to AtriCure's Fourth Quarter and Full Year 2025 Earnings Conference Call. This call is being recorded for replay purposes. I would now like to turn the call over to Marissa Bych from the Gilmartin Group for a few introductory comments.

Great. Thank you. By now, you should have received a copy of the earnings press release. If you have not received a copy, please call (513) 644-4484 to have one e-mailed to you. Before we begin today, let me remind you that the company's remarks include forward-looking statements. Forward-looking statements are subject to numerous risks and uncertainties many of which are beyond AtriCure's control, including risks and uncertainties described from time to time in AtriCure's SEC filings. These statements include, but are not limited to, financial expectations and guidance, expectations regarding the potential market opportunity for AtriCure's franchises and growth initiatives, future product approvals and clearances, competition, reimbursement and clinical trial outcomes. AtriCure's results may differ materially from those projected. AtriCure undertakes no obligation to publicly update any forward-looking statements. Additionally, we refer to non-GAAP financial measures specifically constant currency revenue, adjusted EBITDA, adjusted EBITDA margin and adjusted loss per share. A reconciliation of these non-GAAP financial measures with the most directly comparable GAAP measures is included in our press release which is available on our website. And with that, I would like to turn the call over to Mike Carrel, President and CEO.

Thank you, and good afternoon, everyone, and thank you for joining us. 2025 was an exceptional year at AtriCure with achievements across our business. We closed the year with total revenue of $534 million, reflecting 15% growth over 2024, and made substantial improvements to profitability and cash generation with nearly $62 million in adjusted EBITDA and $45 million in cash generated in 2025. More importantly, 2025 demonstrated the power of our innovation engine. We accelerated worldwide revenue growth in 3 of our 4 franchises, driven by newer product launches such as our cryoSPHERE MAX Probe and AtriClip FLEX-Mini device, continued adoption of our therapies, notably with the EnCompass Clamp, and launched two new products during the year, our AtriClip PRO Mini and cryoXT PRO. As a result of our strong operational execution and meaningful progress across these strategic priorities, we are well positioned for the year ahead and reaffirm our guidance for 2026 revenue growth of 12% to 14%. It is now almost 1 year since we hosted our March 2025 Analyst and Investor Day, where we featured several catalysts for our business and established long-term financial targets. We committed to sustained double-digit revenue growth, expanding profitability and meaningful cash generation, and we have delivered on all three; simply put, we are outpacing the plan. We generated revenue growth of 15% for the year, and the operating leverage in our business is becoming increasingly visible. R&D spend is leveling off with the completion of the enrollment in LeAAPS. Our commercial team is driving efficiency gains in SG&A and our new product launches are contributing to gross margin improvement. In addition to our financial progress, we have advanced key strategic initiatives outlined at our Investor Day. First, our groundbreaking LeAAPS clinical trial completed enrollment of more than 6,500 patients last July, well ahead of expectations. This trial is evaluating the benefit of our AtriClip devices on non-AF patients undergoing cardiac surgery, representing a global opportunity of nearly 1.4 million patients each year. Interest and participation from our trial investigators was outstanding, with more than 500 surgeons across 137 different sites who enrolled in the LeAAPS trial. During the years ahead, we will continue to follow LeAAPS patients as we await the results of the trial. Following LeAAPS enrollment, we initiated our BoxX-NoAF clinical trial, a 960 patient randomized controlled trial aimed at reducing the onset of postoperative Afib in cardiac surgery patients who do not have preexisting Afib. Up to 50% of cardiac surgery patients without Afib will develop postoperative Afib, making it the most common complication in cardiac surgery. The stark reality is that these patients tend to see worse acute and long-term clinical outcomes. Postoperative Afib is also associated with a higher healthcare cost burden, with estimates exceeding $2 billion annually in the United States alone. Using our EnCompass Clamp and AtriClip devices, we believe this trial will demonstrate the benefits of ablation for non-AF patients during cardiac surgery. We are pleased with our progress on the site initiation and enrollment today and look forward to updating you throughout the year. In addition to these landmark clinical trials, we are also advancing development efforts on our dual energy EnCompass Clamp. Our goal for this program is centered around shortening RF ablation times and introducing PFA as a complementary energy source. On its own, our innovative EnCompass Clamp technology was a significant step in streamlining cardiac surgery ablation procedures, leading to increasing adoption. Now by pairing advanced RFA with PFA in our EnCompass device, we will deliver unprecedented speed and flexibility for surgeons. During 2025, we reached two milestones with our development partner and completed first-in-human treatments in December with excellent results. In the year ahead, we expect to finish device and generate development in preparation for the initiation of a clinical trial, marking another key milestone in our product development pipeline. At our Investor Day, we shared our strategy for building upon the greenfield opportunity in surgical pain management, including expansion into amputation procedures. We launched our cryoXT device for pain management and amputation procedures in the third quarter of 2025 and continue to receive overwhelmingly positive surgeon feedback. Patients are recovering faster than ever, experiencing less acute postoperative pain and in many cases, reduced phantom limb pain. We are being deliberate in our rollout with each Cryo Nerve Block, focusing on one account at a time to ensure adoption is sticky before expanding our user base. As we cultivate this opportunity, we expect cryoXT to contribute more meaningfully to revenue in the back half of 2026. Taking a step back, each strategic initiative coupled with continuous product innovation that is the hallmark of AtriCure supports our vision to create standards of care across all of our markets. BoxX-NoAF and LeAAPS also share an objective that is truly transformational for our company, moving standards of care in cardiac surgery towards preventative treatment of Afib and related complications. Both trials enable AtriCure and AtriCure alone to unlock massive market expansion opportunities and future growth acceleration. Now on operational highlights from each of our franchises from the fourth quarter and full year 2025. Starting with pain management. In the fourth quarter of 2025, we achieved 24% growth, driven by continued increasing adoption of our cryoSPHERE MAX device. The time savings offered by this device compared to our legacy probes have been compelling to surgeons, particularly in thoracic surgery. For the year, worldwide revenue grew 33% in 2025, marking an acceleration for 2024 growth. We ended the year with roughly 500 accounts in the U.S. choosing our cryoSPHERE MAX device and saw growth in accounts utilizing Cryo Nerve Block worldwide. In addition, during 2025, we reached over 100,000 patients treated with our cryoSPHERE probes, framing the tremendous growth and patient impact of this franchise since launching in 2019. Turning now to appendage management. We delivered fourth quarter growth of 15% globally, with open left atrial appendage growth well outpacing our MIS left atrial appendage devices. We are pleased with the consistent momentum of our open appendage management business, which powered full year worldwide revenue growth for our left atrial appendage franchise of 19%, again marking an acceleration over 2024. AtriClip FLEX-Mini and AtriClip PRO Mini largely drove this acceleration in growth with the surgeons drawn to the low profile of our mini AtriClip devices. Much of our growth is volume-driven, though we also benefit from a favorable price mix as surgeons convert from legacy devices. We exited 2025 with over 300 active accounts purchasing FLEX-Mini and saw FLEX-Mini contribute 18% of our worldwide left atrial appendage management revenue in 2025, leading to increased market share in the United States. We believe our innovation, along with our robust clinical evidence and superior product performance, has and will continue to differentiate our AtriClip devices from the competition. Within our Afib ablation franchises, open ablation growth came in over 17% for both fourth quarter and full year 2025 with the EnCompass Clamp being the primary contributor. The durability of EnCompass growth since launch in 2022 exemplifies the staying power of AtriCure innovation. As I mentioned earlier, EnCompass dramatically reduced procedure times and simplified open-heart ablation, enabling a deeper penetration in treating Afib concomitant to cardiac surgery. Our EnCompass Clamp is now present in over 830 accounts worldwide, reflecting a mid-teens increase over 2024. In the U.S., our EnCompass utilization is further along as we are seeing adoption largely improve in the penetration of CABG procedures. That said, the treatment of pre-op Afib patients undergoing cardiac surgery remains vastly under-penetrated. At the most recent Society of Thoracic Surgeons (STS) conference last month, we were excited to learn that concomitant Afib treatment is no longer optional. It will be a quality metric in which hospitals will be evaluated and graded by their adoption of this metric. By early next year, it will be included in star ratings, which patients and physicians use to determine who provides the best care. This is only the second time in the past 25 years where a therapeutic treatment has become a quality metric in cardiac surgery, and we want to recognize the contributions of our physician partners to this effort. They have put a stake in the ground related to the treatment of Afib, which will benefit tens of thousands of patients moving forward. This change builds upon existing societal guidelines that recommend treatment, and AtriCure's specific technology, which makes it feasible to treat, placing a spotlight on the opportunity for continued growth in open-heart procedures. Finally, in minimally invasive Afib treatment, our hybrid Afib therapy continued to feel the pressure of PFA adoption in the U.S. in 2025. This was a tough headwind for our business, with full year worldwide revenues declining 26% for 2024. We believe there's a compelling clinical value for Hybrid AF therapy in patients with long-standing persistent Afib. However, it is undeniable that PFA catheters are dominating the stand-alone Afib treatment right now. As we exited the year, we saw an encouraging sign with sequential revenue improvement in the U.S. from the third quarter to the fourth quarter and added accounts performing the conversion procedure. While these signals are positive, we are looking for evidence for further stabilization of a Hybrid franchise, which reflects broad-based and repeatable trends across our customers. We remain prudent in our outlook and are assuming continued pressure in our U.S. Hybrid business in 2026, although we are anticipating a lower rate of decline than in 2025. We remain committed to this market in the millions of patients with advanced Afib who can benefit from our approach. Our team and infrastructure remain ready to scale as the market recognizes the value of Hybrid AF therapy. In closing, 2025 was a year of substantial growth and remarkable execution for AtriCure. Our progress is a testament to the dedication of our talented extended team who remain committed to advancing our mission and our goals. We are delivering better-than-promised growth, financial and strategic initiatives and are excited for our momentum to continue in 2026. We will work to transform standards of care in each of our markets for many years to come. With that, I will turn the call over to Angie Wirick, our Chief Financial Officer. Angie?

Thanks, Mike. For the fourth quarter 2025, worldwide revenue reached $140.5 million, representing growth of 13.1% on a reported basis and 12.1% on a constant currency basis when compared to the fourth quarter of 2024. U.S. revenue grew 12.6% to $114.3 million from the fourth quarter of 2024, supported by robust contributions from newer product launches in pain management and open appendage management, specifically our cryoSPHERE MAX and AtriClip FLEX-Mini devices, along with continued adoption of our EnCompass Clamp in open ablation. International revenue totaled $26.2 million, up 15.3% on a reported basis and 9.9% on a constant currency basis as compared to the fourth quarter of 2024. While our international markets delivered solid growth overall, our fourth quarter results were impacted by a decline in sales in the U.K. due to ongoing funding and reimbursement uncertainty with the National Health Service. The U.K. has been our fastest-growing European market in 2023 and 2024, so this created a meaningful impact in the fourth quarter. Sequentially, worldwide sales grew $6.2 million or 4.6% over the third quarter of 2025. Gross margin for the fourth quarter of 2025 was 75%, an increase of 45 basis points from 2024, driven primarily by favorable product mix. Research and development expenses decreased $10.5 million on a reported basis, largely due to the upfront payment of $12 million for our exclusive licensing and co-development agreement for PSA Technology in the fourth quarter of 2024 and offset by a $1 million milestone payment in the fourth quarter of 2025. Excluding these charges, R&D was approximately 2% higher in the fourth quarter of 2025 compared to the prior period, with a decrease in LeAAPS clinical trial costs offset partially by enrollment activity in our BoxX-NoAF clinical trial. SG&A expenses increased $6.2 million or 8.5% over the fourth quarter of 2024, showing continued leverage when compared with 13% revenue growth. In the fourth quarter, we also continued to build on our momentum on the bottom line, delivering both positive adjusted EBITDA and net income. We drove positive adjusted EBITDA of $19.9 million for the fourth quarter 2025 compared to $12.7 million in 2024. Our net income was $1.8 million versus a $15.6 million net loss in 2024. Earnings per share in the fourth quarter of 2025 was $0.04 and adjusted earnings per share was $0.06, representing a significant improvement over the fourth quarter of 2024, which reported a loss per share of $0.33 and an adjusted loss per share of $0.08. Now to review full year 2025 results. Worldwide revenue was $534.5 million, an increase of 14.9% on a reported basis and 14.4% on a constant currency basis, well ahead of our initial 2025 guidance range of 11% to 13% growth. U.S. sales increased 13.7% to $435.4 million, and international sales increased 20.2% on a reported basis and 17.5% on a constant currency basis to $99.2 million. U.S. open ablation sales increased to $143.8 million or 16.3% growth over 2024, driven by continued strength from EnCompass Clamp sales, which ended the year contributing over 60% of our U.S. open ablation revenue. Our U.S. pain management franchise grew 32.5% to $81.9 million propelled by rapid adoption of the cryoSPHERE MAX probe in both new and existing centers. U.S. appendage management sales reached $178.1 million, a 17.5% increase over 2024, with approximately 24% growth in open appendage management devices offset by a 6% decline in MIS appendage management devices. The primary driver of open appendage management growth in 2025 was the adoption of our AtriClip FLEX-Mini device. Finally, U.S. MIS revenue was $31.5 million, reflecting a 31.2% decline over 2024 as customers prioritize PFA catheters over our devices. Our Hybrid business was a strong headwind throughout 2025, with a $16 million total decline in our U.S. MIS ablation and MIS appendage management devices. However, taking a step back, the combined strength of our U.S. open ablation, open appendage management, and pain management franchises grew U.S. revenue by nearly $69 million or 22% in 2025, more than offsetting the pressure from Hybrid. International revenue saw robust growth across major geographic regions of franchises, except for pressures in the U.K., as mentioned previously. We were pleased to see continued strength in our appendage management devices across international markets in 2025, and the acceleration of our open ablation franchise growth, partially due to the launch of our EnCompass Clamp in Europe. Gross margin for the year ended at 75%, an increase of 29 basis points from 2024, driven primarily by a more favorable product mix as well as continued production efficiencies as we scale. Turning to operating expenses. Full year 2025 operating expenses increased 5.9% to $410.2 million, up from $387.5 million in 2024. Research and development costs as reported expanded by $3 million or 3.2%. Research and development costs include the upfront payment associated with our PSA partnership agreement in '24 as well as the milestone payments in 2025. Excluding these charges, 2025 research and development expenses grew approximately 11%, driven by LeAAPS and BoxX-NoAF trial costs and a modest increase in head count and related spend. SG&A expenses increased $19.7 million or 6.7%, primarily on increased head count and demonstrating improving leverage. Going forward, we remain committed to funding key R&D initiatives that support innovation and growth while expanding our total operating leverage across the business. Full year 2025 adjusted EBITDA was $61.8 million compared to $31.1 million in 2024, an improvement of $30.6 million. Our loss per share was $0.24 in 2025 compared to a loss per share of $0.95 in 2024, and adjusted loss per share was $0.11 and $0.67, respectively. We ended 2025 with $167.4 million in cash and investments, reflecting full year cash generation of approximately $45 million. With these results, we continue to bolster our balance sheet, showing efficient capital management and ensuring financial flexibility to support future growth. And finally, turning to our outlook for 2026. Consistent with our guidance in early January, we expect to achieve between $600 million and $610 million in revenue for the year, translating to growth of 12% to 14% over the full year 2025 results. From a franchise standpoint, we anticipate pain management will lead growth again in 2026, followed by open appendage management and open ablation growth more closely aligned to the overall guidance range. As Mike mentioned in his remarks, while we remain cautiously optimistic about minimally invasive ablation and MIS appendage management, we do expect a decline in revenue in 2026, although at a moderated rate. Geographically, we anticipate both the U.S. and international businesses to deliver growth at rates that are more closely aligned during the year, as our outlook contemplates ongoing uncertainty in the U.K. for the duration of 2026. Finally, in terms of quarterly cadence, we expect typical seasonality to broadly shape the year on a sequential basis, with first quarter revenue tracking roughly in line to down slightly with the fourth quarter of 2025. From a margin perspective, we anticipate that we will see modest gross margin expansion in 2026 from the benefit of product and geographic mix as well as cost savings initiatives. Additionally, as we've shown in 2025, we would anticipate some variability each quarter based on product and geographic mix. Looking at operating expenses, we will continue to exercise disciplined capital allocation, focusing our investments on the next generation of growth drivers for AtriCure. We project research and development expenses to moderate slightly, growing in low teens on an organic basis and mid-teens factoring in PFA milestone payments in 2025 and 2026. Additionally, we expect SG&A spending to continue to grow below top line growth rates, supporting further improvements in overall profitability. On the bottom line, we are excited to reaffirm our 2026 expectation for adjusted EBITDA range of $80 million to $82 million and full year net income. With the expected cadence on top line and normal first quarter activities, our adjusted EBITDA margin will step down from the fourth quarter 2025 exit rate and gradually build during the year. Our adjusted EBITDA guidance corresponds to full year earnings per share of approximately $0 to $0.04 and adjusted earnings per share of $0.09 to $0.15. We also anticipate another year of positive cash generation. As a reminder, we typically experience higher cash outflows within the first quarter of the year due to annual variable compensation payments, share vesting and operational investments. And with that, we anticipate a net cash burn in the first quarter of 2026, followed by positive cash generation for the remainder of the year and full year 2026. Overall, we delivered strong results in 2025 and the outlook for our business demonstrates our commitment to expanding profitability while also enabling key strategic growth initiatives. We will continue the trajectory from 2025 to exceed our long-range financial targets discussed at our Analyst and Investor Day last March, driving double-digit revenue growth towards our $1 billion revenue goal in 2030 and while improving profitability over 20% adjusted EBITDA margin, all with a focus on creating long-term value for our shareholders.

Thanks, Angie. In closing, I want to recognize our team for an outstanding year. You remain focused on patients, executed with discipline, and never lost sight of the standards of care we are trying to build. We are well positioned to raise the bar again in 2026, and I am confident in our ability to continue delivering operational excellence across the business. And with that, we'll turn it over to questions. Thank you.

Our first question comes from William Plovanic with Canaccord Genuity.

Great. First off, some recent news from a competitor had a significant impact on your stock. Could you share your thoughts on their entry into the market and how it might affect your competitive position? Additionally, regarding the LeAAPS trial, you're continuing with follow-ups. You've mentioned that we can expect to see data at 50% and 75% of the event rate. Has there been any change in the timeline for when we might receive some of that data, or could it be coming in faster than expected?

Thank you, I appreciate that. We're very aware of the competition entering the market. From our perspective, it actually validates our market position, showing that two major top 5 medical device companies believe that cardiac surgery is a significant growth area. This indicates that we've established a leadership position in this space, and we're proud of that. We welcome the competition. Previously, when a competitor entered the market, we saw an increase in our revenue growth rate. In 2025, our open left atrial appendage management business grew by 24% compared to 2024, which demonstrates the positive impact of this competition. More discussions are taking place about managing the appendage, and this is reflected in quality metrics. This trend was recognized years ago as a significant underpenetrated market opportunity. We are well-equipped for this competitive landscape because we have invested in innovation over the past 10 to 15 years. We are on the 10th generation of our product, offering both minimally invasive and open chest products, and we have established ourselves as a global leader with over 750,000 implants and an impressive safety rate of 0.07, proving that our product works safely every time. The efficacy is also excellent. We continue to innovate, as seen with our FLEX-Mini product, which has shown accelerated growth, and the PRO Mini launched last year. We have another new product slated for release in 2027. We remain committed to innovating and investing in clinical evidence. As you mentioned, the LeAAPS trial involved 6,573 patients, with half receiving the AtriClip and half receiving no treatment. This trial aims to demonstrate stroke reduction in patients undergoing cardiac surgery without pre-operative Afib. We believe this will provide additional differentiation, especially given our studies involving over 21,000 patients in more than 100 peer-reviewed publications over the past decade. To address your question about the timing of the LeAAPS data, we won’t be sharing specific data on when we reach the 50% mark. We only receive confirmation to continue once we surpass 5% to 50% in terms of events. The trial is ongoing and progressing well, and we receive positive feedback from the committee. The next evaluation will happen at the 75% mark, with final results being gathered at 100% of all events. If there’s been any confusion, we only get a positive thumbs-up for continuing rather than specific data to release early. This is a positive indication, as the DSMB's feedback has been encouraging for us to proceed.

Our next question comes from Matthew O'Brien with Piper Sandler.

Anna, this is on for Matt. So maybe to start for the guide for the year, I appreciate you reiterated the metrics you provided earlier this year, which is really good to see. I guess just with this new competitive entry in the Clip business, any color you can provide on how that might be contemplated into the guidance that you've set out today?

Anna, it's Angie. I think as we started to form our guidance range for 2026, we were expecting this kind of news to come out. I think it was discussed pretty widely with the investment community last year, so not a big surprise here as we look through the year. We have factored in some very mild competitive pressures as we think about the back half of the year. I think we're focused on within our business controlling what we can, which is continuing to spread the adoption of the FLEX-Mini Clip. It is an excellent product and want to make sure that as many customers as possible have their hands on this prior to the competitive entry. Ultimately, we think by doing that and continuing to focus on our markets, both Afib and non-Afib patients, we will ultimately set up for a really good year from a growth perspective.

Got it. Super helpful. And then, I guess, a little bit more on the Clip business. It came in a little bit softer than we were modeling this quarter, particularly in the U.S. So just any more color you can provide on the dynamics there and how you're thinking about that business going forward?

Yes. The softness that we saw, particularly in the U.S., came in our minimally invasive Clip, we were down about 6%. We had a nice quarter in the third quarter, I think, with a lot of accounts choosing to adopt the PRO Mini product, the new product that we launched in 2025, kind of middle of the year, and saw a bit of softness there. I think until our Hybrid ablation business sees kind of growth in procedures year-over-year and on a repeat basis, we would expect some variability on that end. I think if you take a step back and open appendage management, we were high teens growth in that area of the business for the fourth quarter. Mike talked about in his prepared remarks, open appendage management growth for the year. I think that's showing the testament of the innovation with our FLEX-Mini Clip and growing awareness and interest in treating appendages during cardiac surgery.

Our next question comes from Mike Matson with Needham & Company.

So I have one, just on LeAAPS. Since the enrollment stopped, I was wondering if that had any impact on your AtriClip business. I guess, can you remind me, were you getting paid for the clips that were used in that? Or were you guys covering the cost of those?

Mike, we do get paid for the devices that were used in the trial. As Mike mentioned, the LeAAPS clinical trial was randomized 1:1. So half of those devices ultimately would have been revenue generating for us as a business. I think when you take a step back and look at the volume of open appendage management devices that we do, it's a minimal contribution in any 1 quarter that we were doing enrollment. I would also say, and I think we've talked about this quite a bit with investors, there were a number of surgeons who were enrolling in the trial who believe in prophylactic treatment. So by them enrolling in the trial, they were forced to randomize their patients 1:1. So I think there are probably some areas where we were losing revenue, so to speak, offset by other surgeons who were enrolled in the trial and weren't necessarily prophylactically treating. The overall message here is, yes, revenue contributing, but I'd say on the volume that we were doing, not significant to any 1 quarter.

That's helpful. I'm trying to understand what it means. I know it was around last summer. Regarding EnCompass, it's clearly been a successful product for AtriCure, and while you're developing the dual energy version, which will require trials and likely take a few years, do you have any new versions or enhancements planned in the meantime to help drive the price mix and increase penetration into CABG?

We currently do not have a new product iteration planned. As a reminder, we initially launched the long version, followed by the short version last year, which helped us accelerate our market presence. The market penetration in CABG is still low, and we will continue to engage with those customers, provide training, and conduct related activities. Additionally, we are running the BoxX-NoAF trial, which exclusively uses the EnCompass Clamp alongside the AtriClip. This trial provides an opportunity to engage more sites that were not previously EnCompass users, particularly at major academic institutions. It's crucial to involve these surgeons. We anticipate gaining traction for the EnCompass Clamp from various avenues, but we do not have any new innovations in the pipeline at this time, nor do we believe they are necessary. Currently, the product is demonstrating procedure times of less than 10 minutes, which is impressive considering the effective ablation we achieve in such a short time. We are also seeing an increase in published articles, including a recent peer-reviewed study showcasing almost 90% success at the one-year mark with over 150 patients. We are seeing excellent results and need to keep raising awareness about its benefits and the importance of achieving full ablation.

Our next question comes from Marie Thibault with BTIG.

I wanted to see, maybe it's a little too in the weeds, but I wanted to see if you could help us size the part of your U.S. appendage management business that might be directly in competition with the new entrants. One way I was thinking about it is maybe thinking about those open clips that are used in concomitant valve surgeries. And I wondered if you were able to size that for us against sort of the 2025 U.S. revenue you did in appendage management.

We haven't given really specific guidance on those particular areas. As we know that the overall market in this space is there's about 300,000-or-so patients that undergo cardiac surgery. With the combination of the LeAAPS trial and the Afib patients overall, we believe that, that's obviously a very large market opportunity. About 170,000 to 180,000 of those patients are coronary bypass patients. So you've got the breakdown that, that is obviously a market that we will be in and is not obviously connected to the valvular space. I think you guys can see the numbers that it's what, 35,000 to 40,000 or so mitral valves and something similar along those lines, maybe a little bit higher on the aortic valve side, depending on which reports that you look at overall. And then there's obviously other surgeries that kind of happen to kind of make up the total number overall. When you break down that particular market, when you look at it that way, we're obviously very strong in the valvular market today. That is where a great deal of penetration is, but we also have great advantages in that market, in the sense that usually when people are treating in the mitral valve space, they're also doing ablation at the same time. That ablation is critical to the success of that surgery to the recovery of those patients. Penetration is much higher in the mitral valve space in that area, something around 60% to 70% of patients with Afib are actually getting treated, with something whether it's an EnCompass Clamp or our PRO devices or other RF devices combined with AtriClip at the same time. It's part of the Cox-Maze procedure that is there. So we feel like we've got a built-in advantage in the sense that we've got over 300 people out in the field that understand how Afib is treated, how you need to treat it properly in the combination of the AtriClip with the ablation devices is a critical understanding that we have that others don't necessarily have from that standpoint. As we look at the CABG market, obviously, that is a greenfield approach, and we're the only ones really in that space exclusively from that standpoint.

Yes. That's great detail, Mike. A quick follow-up for Angie. I heard your discussion of modest gross margin expansion, which we're excited to see. On the OpEx leverage, we're seeing SG&A leverage. Could we get a little bit of R&D leverage as well this year as you kind of switch out the trial costs you were going on?

I think you nailed it, Marie. I'd say on all angles expect modest gross margin improvement. We are seeing the newer product launches, particularly with the strength and uptake in the U.S. markets, contributing to an improvement in our gross margin. Our operations team has also been very focused on some of our highest selling products like the EnCompass Clamp. I can't necessarily call it a new product launch because it's been in the market for a couple of years now in the U.S., but streamlining those costs there. So you're seeing the benefit of that. You saw that more in earnest as we exited 2025 and expect that to continue into 2026. Expect SG&A growth to be below top line growth. That was an area of leverage for our business significantly in 2025 should be an area of leverage in 2026. And the last point on the R&D costs, with the conclusion of enrollment in LeAAPS, we are seeing a step down in those clinical trial costs. We still follow patients, so there is still spend on the P&L. We are expecting a pretty strong year from BoxX-NoAF enrollment perspective. But the mix, the different trial design and size of both of those trials says you're going to start to see some pretty natural leverage coming through within R&D. What we said in our prepared remarks is expect on an organic basis kind of low teens growth in that area.

Our next question comes from Lilly Lozada with JPMorgan.

Great. Maybe I'll start with one, on profitability. You already hit the 14% adjusted EBITDA guidance that you pointed to at your Investor Day this current quarter. And you still have a few years to go before getting to the end of the LRP. So is the 14% just conservatism? And if not, what other dynamics will we be keeping in mind as it relates to the progression of adjusted EBITDA moving forward?

Good question, Lilly. The 14%, super happy with the performance, obviously, in the fourth quarter on the bottom line, a big milestone for our company, not only the 14% adjusted EBITDA but pulling in positive net income for the quarter. As we think about going forward, I would expect there to be a step down. So 2026, the full year shouldn't look like a full 14%, but we are significantly ahead of our LRP estimates when it comes to the bottom line movement there as well as our top line growth rate. So I think the dynamics to focus on when we say we're kind of ahead on the bottom line, we've been talking about driving efficiency within the P&L and in our business for a very long time. I think you're seeing the benefit of size and scale and previous investments ultimately driving us to this point here. As we look forward, our main priorities are continuing to invest in kind of game-changing clinical trials, LeAAPS and BoxX-NoAF are both those, and also making sure that our product portfolio and platforms continue to meet market needs. Each one of our markets is significantly underpenetrated even still today. So we see a lot of opportunity, and internal development efforts are a clear priority for us. So we're pleased with the progress on the bottom line and would expect to well exceed kind of the '28 goal here in the near term from an adjusted EBITDA perspective and look forward to continuing to charge towards the 20% EBITDA margin towards the end of the decade.

Great. That's helpful. And then just as a follow-up, open with EnCompass has continued to be really strong. Can you talk through how many patients you've treated with EnCompass in 2025 and where penetration for the product stands relative to the total opportunity? And can you help quantify how meaningful of an opportunity you think the inclusion in the star rating is?

Yes. Maybe I'll hit on it. If you look at globally, there's 2 million patients that undergo cardiac surgery. In 2025, we treated about 50,000. So we're still obviously very underpenetrated in that market. Both the LeAAPS and the BoxX-NoAF trial are international trials. So the idea is not just to get a label in the U.S., but to also get additional reimbursement and market expansion opportunities in countries throughout the world. By including them in the trial, I think that makes it a lot easier and smoother to kind of get that for a trial of that size and scale to go after those markets. So on a global basis, we are very under-penetrated overall in the market, not just on EnCompass, but on cryoRF, etc., because there are obviously a lot of surgeons that continue to use some of the original technology that we have that work incredibly well and treat patients today. EnCompass obviously is a big growth driver. You can see there's just lots of opportunity for us.

Our next question comes from Danny Stauder with Citizens JMP.

Yes. Great. So just first one for me. On international sales, you called out the U.K. budget issues. Did that have a more notable impact to any specific segment? It looked like international pain management was down slightly. So maybe it's there. And then how much was that in terms of headwind to total sales as well as maybe on a segment basis during the quarter? And how should we think about this going forward in 2026?

Yes. Danny, when you break down the different franchises in the U.K., the two areas where we saw the most impact were our pain management device for which the NHS pulled reimbursement and said they felt like it should be covered under different codes. So we saw a significant reduction in the procedures there. The other area that we saw was in stand-alone treatment of Afib, so our minimally invasive ablation business. That's an elective procedure. So saw a bit of weakness there as they're prioritizing the more emergent procedures. A little bit less of an impact when you think about our open cardiac procedures. Those tend to be emergent and needed to be done. But those are the areas that were impacted broadly across the U.K. We talked about this as one of our fastest-growing markets in Europe over the past couple of years. We were on about a $4 million run rate per quarter and saw that drop down a little over $1 million in the fourth quarter, which is really when we saw the big impact for 2025.

Got it. No, that's helpful. And just one follow-up for me on cryoXT. You mentioned you were being more deliberate with your rollout. This might be because it's a little bit different of a sales point. So I was curious if there are any more substantial training with surgeons compared to your prior launches? Or any more nuance on this cryoXT launch as we think about our model and as it ramps up?

Yes, that's a great question. We're approaching new product areas like cryoXT similarly to how we handled the EnCompass rollout. Initially, we took our time, particularly during the first 6 to 12 months, to learn about the procedure and understand how it works with various surgeons. We collected feedback and used it to enhance our training for surgeons as we progressed. Once we felt confident, we expanded our efforts. The same approach applies to XT, a new area for us, as we engage with vascular and orthopedic surgeons, whom we haven't typically worked with before. We want to ensure we get it right and gather their insights as we expand to more sites. Currently, we are in a learning phase, but we plan to open it up significantly by the middle of this year. The feedback on XT so far has been positive, but there is always a learning curve when entering a new therapeutic area with new surgeons.

Our next question comes from John McAulay with Stifel.

First one on the PFA program. I was hoping for an update there. A couple of dynamics. I noticed one versus our model, and we might have been mismodeling it, but costs that you paid in the quarter was lower than we were expecting to your PSA partner. And could you just clarify if that was, again, mismodeling on our part or the charge was pushed out? And then just any potential impact on timing there and when we can expect our next update and for a trial to get going?

Yes, John, I don't think it's mismodeling. We had said kind of a range of potential milestones that we would thought could be met within 2025, the third milestone roughly, call it, $4 million pushing into 2026. Everything is on progress. I think the big news coming out of this particular work is that we had first-in-human use with really good results as we thought through the back end of 2025.

And it doesn't change the timeline to add to that. I think the second part of your question was as we look forward and get ourselves ready for a clinical trial design, on that front, we will be ready in the same kind of timeframe we talked about at the Analyst Day.

That's helpful. And I think it was last month, you made some comments about CONVERGE and some improvements in a few accounts, so I understand the dynamics are still fluid. You're still expecting declines this year, albeit at a lower rate. Just wanted to get an update about 1 month on just the state of the field for CONVERGE, what you're seeing on the ground, particularly post the Afib symposium, just any meetings with customers there and how the dynamics are looking now versus either a month ago or a year ago, however you think you'd optimally frame it?

I think that we continue to feel like there is optimism and light. We're seeing many sites that had previously done CONVERGE, went away from it as they got in the PFA are now starting to do it, but it's just not enough cases to feel confident to come out with a number that says, okay, I've got confidence that consistently every single quarter, we're going to be at a point that we can grow that. But you are seeing those sites come back. They want to get retrained, or they want to kind of look at their workflow again. So the good news is that we've got a lot of new sites coming on board from that standpoint, just not enough to move the number at this point in time. So it's a positive outlook, but it's not ready to commit to anything relative to numbers as we look out throughout this year. But it is moving in the right direction, as we saw in Q4, and we do feel like we're in a good place, and we're having a lot of good conversations with customers right now.

Our next question comes from Danielle Antalffy with UBS.

It's Jayna on for Danielle. I know we're in the early innings of pain management expansion. And I know that you said reps are staying in one account until it's sticky. But I was just wondering, those reps that have successfully been executing. How long are they in the accounts before they're pivoting to the next account?

It's not about time; it's about getting the number of cases down with them and making sure that they're doing it properly. They've got a protocol right, not just with the surgeon, but also with the kind of after intensive care unit once they kind of have a step-down units in those areas, and how they care for these patients. We do believe that it takes, let's say, it's a 3-month or so process, but it really means they've got to get 10 to 15 cases underneath their belt to really feel really comfortable before we're ready to move on and get that consistency going that we can learn from them on that front. But we're seeing good progress in a lot of different accounts. Almost every one of our reps has an account that is actually using the product today, so they're already down that pathway, and we've got a pretty good size field team out there.

That's great to hear. And then on open ablation, specifically, how much runway is left from a CABG perspective? And then also, I know you're talking about getting more implanting physicians from the new trials like BoxX-NoAF. I was just curious if you could comment on the percent penetration from that perspective as well.

Specifically to CABG, if you look at Afib patients alone, it's around 20% of the patients that undergo cardiac surgery have Afib, and they're undergoing it for coronary bypass, about 20% of those patients get it. But if you look at it in totality, when you start to think about BoxX-NoAF and the expansion opportunity that exists there, that number is obviously much less than 10%, and when you add in the non-AF patients. So big market opportunities still sitting in front of us.

And our final question comes from Suraj Kalia with Oppenheimer.

Mike, Angie, can you hear me all right?

Yes.

We can.

Perfect. So Angie, I have a question, and I apologize if it's a bit lengthy. I wanted to follow up on an earlier inquiry. If you look at the U.S. AtriClip for the last three quarters of 2025, it seems relatively flat. Can you help clarify some of the dynamics at play? You mentioned that the drop-off in MIS was compensated by open procedures, which is fine. Can you provide an estimate of the LeAAPS contribution? Additionally, what was the impact of the new product introduction on the average selling price? There are a lot of variables here, and I'm trying to understand the situation better. Mike, quickly, what is preventing [indiscernible] from launching next year, specifically in Q1 or Q2 of 2027? Why can't [indiscernible] be used preventively after any cardiac surgery given the timeline before the LeAAPS data becomes available?

All right. I'll start, Suraj. With your questions, I'd say the dynamic when you're seeing some of the variability on our appendage management line item franchise, it is primarily within our MIS clipping. We talked about in the third quarter we had a stronger quarter with adoption of the PRO V or PRO Mini product, I should say. If we've seen MIS appendage management devices throughout the year, see quite a bit of variability for that to grow in earnest, we need to see growth within our hybrid ablation franchise, which obviously was on a downward trajectory throughout 2025. When I take a step back, we've seen strong growth within our open appendage management devices throughout 2025. When I take a step back in any one quarter, it is a couple of points for our open appendage management products as AtriClip FLEX-Mini takes hold. That is the difference between volume and overall reported revenue growth. It's a couple of points that is pricing related. We are seeing a lot of customers switch over to our FLEX-Mini device. They like the lower profile that that device provides, and it comes with the track record and strength of our previous AtriClip platform.

To address your question about the preventative measures at launch, I want to highlight the advantages we currently have in the market. Our products demonstrate exceptional safety and efficacy, and we're excited about our upcoming next-generation product launch in the middle of next year. We believe our offerings will outperform all other products available. We have conducted studies with over 21,000 patients showing significant closure rates, backed by 100 peer-reviewed articles and exceptional implementation safety rates. Customers recognize our commitment to investing in clinical evidence and understand that we are the only company making such substantial investments in this area. We are conducting major randomized controlled trials, and history shows that those who invest in data and validation ultimately succeed. Combining our superior products with solid clinical evidence typically prevails in the long run. This pattern is evident in markets like the left atrial appendage and occlusion markets, and we anticipate similar outcomes in our field. We are also preparing for the entry of competitors who may try to emulate our successes and leverage our clinical trials and guidelines. We respect our competitors, but we remain focused on earning our customers' business daily through innovation, clinical evidence, and an exceptional field team. Our clinical and educational teams have a deep understanding of appendage management and Afib. I have strong confidence in our team, even as competitors may emerge and shake up the market. Typically, market growth occurs when significant players enter the space. When WATCHMAN entered the market, for instance, it helped expand the overall market. We believe that the market will continue to grow, and we will capture our fair share due to the strengths of our products and team.

This concludes the question-and-answer session. I would now like to turn it back to Mike Carrel for closing remarks.

Great. Everyone, thank you for joining us on the call today. We look forward to a great Q1 and talking to you again in the April, May time frame. Have a great night. Bye now.

This concludes today's conference call. Thanks for participating. You may now disconnect.
