NeuroPace Inc Q3 FY2025 Earnings Call

Thank you for joining us. My name is Colby, and I will be your conference operator. I'd like to welcome you to the NeuroPace Q3 earnings call. Now, I will hand the call over to Scott Scaper, Head of Investor Relations at NeuroPace. Please proceed.

Thank you, operator, and welcome to NeuroPace's Third Quarter 2025 Earnings Conference Call. Our agenda begins with Joel Becker, NeuroPace's Chief Executive Officer, who will summarize our recent highlights and ongoing strategic initiatives, followed by a financial review and outlook from Patrick Williams, our Chief Financial Officer. Following our prepared remarks, we will open this call up for your questions. At that time, we ask the analysts to limit themselves to one question and one follow-up question each, so we can provide an opportunity for everyone participating today. Let's quickly review our safe harbor statement. Some of the statements we will make on today's call may constitute forward-looking statements. These statements reflect management's intentions, beliefs, and expectations about future events, strategies, products, regulatory, and operating plans and performance. All forward-looking statements included on this call are made as of the date hereof based on information currently available to NeuroPace and are subject to various risks and uncertainties, and actual results could differ materially from those anticipated in the forward-looking statements. The factors that could cause actual results to differ materially from those expressed or implied by any of these forward-looking statements are detailed in NeuroPace's annual report on Form 10-K, most recent quarterly report on Form 10-Q, and other filings with the Securities and Exchange Commission. Except as required by law, we assume no obligation to update any such forward-looking statements after the date of this call or to conform these forward-looking statements to actual results. And with that, I will now turn the call over to NeuroPace's Chief Executive Officer, Joel Becker. Joel?

Thanks, Scott, and good afternoon, everyone. I will start with an overview of our third quarter results and how the team is executing against our strategy. I will then provide updates on our key clinical and product development initiatives. After that, Patrick will walk through the financials and updated guidance before opening the line for Q&A. The third quarter was one of record results for NeuroPace and a demonstration of the effectiveness of our strategy and its execution. Total revenue in the quarter was $27.4 million, delivering 30% year-over-year growth compared to $21.1 million in the prior year quarter. This record revenue was primarily driven by RNS initial implants, resulting in RNS revenue of $22.6 million and representing growth of 31% year-over-year. RNS growth in the quarter was broad-based across geographies, customers, and programs. All sales regions exceeded planned sales for the quarter with the number of prescribers, accounts, and utilization nationally reaching all-time highs. These results demonstrate the compounding effects of the recognition of the differentiated capabilities of the RNS System, enhanced commercial leadership and execution, and improved referral management, driving higher procedural volumes. The majority of our growth came from Level 4 centers with increased adoption and utilization. Project CARE also contributed meaningfully and again improved sequentially and year-on-year. We also saw increased contribution from our direct-to-consumer efforts as well. We remain confident in our long-term growth trajectory of growing a minimum of 20% in our core RNS business with our current adult focal epilepsy indication. Importantly, gross margin and operating leverage were also strong and continue to be highlights as we scaled growth in a disciplined manner. Additionally, during the quarter, NeuroPace generated positive adjusted EBITDA, a significant milestone for the company and the first time in our history. This important accomplishment reflects the scalability of our model and the progress we are making with disciplined expense management, consistent mix improvement, and increasing efficiency in both commercial and manufacturing operations. We are proud of this achievement. And while this metric may vary quarter-to-quarter, we remain committed to driving toward sustainable profitability and cash flow breakeven. Given the performance in the quarter, we are raising both our full year revenue and gross margin guidance ranges. For revenue, we now expect a range of $97 million to $98 million or 21% to 23% year-over-year growth, an increase from previous guidance of $94 million to $98 million. Let me now turn to our key clinical and product development initiatives, starting with NAUTILUS and our recent meeting with the FDA. As expected, we completed our pre-submission meeting with the FDA in September, which we believe was a productive and engaged discussion of the study. We reviewed the totality of the evidence, safety, the primary effectiveness endpoint, and the prespecified secondary endpoints, as well as additional analysis. We continue to believe the safety and effectiveness profile of the NAUTILUS data supports a favorable benefit-risk assessment for this highly underserved population, and our PMA supplement will incorporate the discussion points from our meeting. We appreciate the opportunity to meet with the FDA and the dialogue was consistent with our expectations. The development of our PMA supplement application is underway, and our timeline and plans remain on track to submit the PMA supplement for NAUTILUS before year-end. Moving on to our pediatric indication. We continue to work closely with the FDA and our collaboration partner, NEST, as we finalize the real-world evidence and protocol for our pediatric indication. We are working to ensure that the data set and protocol are both as strong as possible. As we continue this process, it has taken more time to align on that protocol and data set than we had initially built into our timeline. We remain confident about the approach of leveraging real-world evidence to gain this much-needed indication expansion in a pediatric patient population. As we finalize the real-world evidence and protocol timing for submission will extend beyond 2025. We are not providing a revised submission date today, but we will provide updates as milestones are met. We are appreciative of the quality of the interactions with the FDA and NEST and the ongoing collaboration as we pursue this unique opportunity. We look forward to advancing this indication expansion pathway and remain committed to bringing RNS therapy to the pediatric population. I also want to highlight the growing recognition that RNS and our unique closed-loop stimulation is receiving across the field. The September issue of the Journal of Clinical Neurophysiology was entirely dedicated to the use of data and feedback for personalizing intracranial neuromodulation and several articles featured RNS at the center of that conversation. This journal is one of the most widely respected peer-reviewed publications in the field of epilepsy and brain modulation. It is the official journal of the American Clinical Neurophysiology Society and a key forum where leading researchers and clinicians publish data that shape standards of care. The editors described a critical shift underway in epilepsy therapy, away from one-size-fits-all stimulation and toward data-guided patient-specific neuromodulation. Driving that shift is the convergence of long-term intracranial EEG, advanced neuroimaging, and artificial intelligence, and the critical importance of developing individualized treatments in clinical settings. For years, the RNS System has generated data and outcomes that define what personalized closed-loop therapy could be. Now as AI and computational tools mature, the importance of the RNS System's unique ability to monitor and record data and then tailor individual therapies for specific patients through its differentiated closed-loop capabilities is coming further into focus. We believe the broader scientific community is recognizing that the RNS System platform is best positioned to capitalize on this new era of innovation that is beginning to shape the future of epilepsy neuromodulation and brain-computer interface development. We are now seeing a number of factors we have been working on deliberately for years start to come together at the same time. The clinical maturity of closed-loop neuromodulation, the scale and quality of our long-term intracranial EEG data set, and the computational tools to act on that data in real-time. And critically, we now have the tenured domain knowledge and execution muscle on the team to capture this opportunity. This convergence is creating an environment for the potential of accelerated adoption of closed-loop personalized neuromodulation. We believe the RNS System is uniquely positioned to capitalize on this new era of data-guided epilepsy care and longer-term on the direction the field is heading in neuromodulation and brain-computer interface or BCI. Now to an update on product development. Our RNS development pipeline is focused on extending the platform advantages just mentioned with greater on-device analytics capabilities, streamlined programming workflows, and enhanced connectivity to further improve both the quality and time to improved outcomes as well as enhance efficiency and ease of use to support wider adoption. We recently submitted to the FDA our seizure iEEG AI software tool, the first of a suite of planned NeuroPace AI applications, which utilizes our proprietary iEEG data and AI development efforts and is designed to improve clinical outcomes. With that, I'll turn it over to our Chief Financial Officer, Patrick Williams, to review the financials and our outlook.

Thank you, Joel. Before getting into our results, I wanted to take a moment to reflect on my first full quarter with the company. The strength of the product, the commitment of the team, and the sheer scale of opportunity still ahead is now much clearer to me and makes me even more optimistic. The execution improvements being undertaken and feedback from physicians I have met with have reinforced that this is a company with a differentiated technology and a long growth runway. In today's press release, we have provided a financial supplement, which breaks out our historical RNS, DIXI, and service revenue by quarter from Q1 2024 through today's Q3 2025 results. We believe this additional detail will allow investors and analysts to more easily reconcile our historical performance with our go-forward reporting structure as we move into 2026, where we will be substantially done with distributing any further DIXI product. Let me now walk you through our third quarter financial results. Our third quarter revenue growth was driven primarily by continued strength in our RNS system sales, totaling $22.6 million, representing growth of 31% compared to the prior year period, supported by higher procedural volumes, broad-based increased utilization within existing centers, and growing contributions from Level 3 and community centers as our investment and focus in these areas scale. Additionally, we generated approximately $770,000 of research service revenue in the quarter tied to our ongoing data collaborations. DIXI sales grew 8%, coming in at approximately $4 million in the quarter as the distribution agreement officially ended on September 30, and the entire company begins to focus more on RNS in line with our strategic rationale. As a reminder, the distribution agreement with DIXI provides for a 6-month wind-down period, which lasts until the end of Q1 2026. At the end of this wind-down period, the distribution agreement contractually allows NeuroPace to sell back any remaining inventory at prior paid costs back to DIXI. Thus, there is minimal to no inventory excess or obsolescence exposure related to this termination. Finally, although the distribution agreement allows for a wind-down period through Q1 2026, we currently believe we will be substantially done with DIXI sales by the end of 2025. We do not expect any material sales in Q1 2026 as our organization and notably, our commercial team strategically shifts its focus solely on our core RNS business and the potential upcoming FDA approval of expanded indications. We are raising our full year revenue guidance to a range of $97 million to $98 million, up from our previous guidance range of $94 million to $98 million. This updated guidance reflects an increase of approximately 21% to 23% over our reported total revenue for 2024. Our increased revenue guidance is primarily driven by our RNS System, which we expect to be in the range of $20 million to $21 million in the fourth quarter. At the midpoint of this range, RNS revenue growth for the second half of 2025 would be approximately 23%, an acceleration over our RNS first half revenue growth results of 21%. This revised total company guidance incorporates a lower contribution from DIXI products of approximately $3 million in the fourth quarter due to the aforementioned strategic shift and wind down of the DIXI product line. And with regard to service revenue, we expect approximately $750,000 in the fourth quarter, similar to our third quarter results and is based on our current projections of achieving certain milestone triggers outlined in these service contracts. Turning to gross margin. Total company gross margin for the third quarter 2025 was 77.4% compared to 73.2% in the prior year quarter and 77.1% in the second quarter 2025. RNS System gross margin remained very strong at above 80%, benefiting from improved manufacturing efficiency, favorable pricing, and continued leverage as we scale. This strength was partially offset by the lower-margin DIXI products, which carry gross margins slightly below 50% and were again impacted by incremental tariffs. Based on our strong year-to-date gross margins and increasing revenue contribution from our higher-margin RNS product, we are raising our full year gross margin guidance to a range of 76% to 77%, up from our previous guidance range of 75% to 76%. As we move into 2026 and substantially exit the DIXI product line, our revenue and gross margin will essentially only be the RNS system, which we believe will carry a gross margin greater than 80%. Total operating expenses were $23.8 million in the third quarter of 2025 compared with $19.7 million in the prior year quarter, in line with expectations with better-than-expected general and administrative expense and areas of research and development expense, offset by higher-than-anticipated selling expenses due to an overperformance in sales as well as higher variable compensation accruals across the organization. Operating expense growth of 21% in the quarter remained meaningfully below our revenue growth of 30%. Stock-based compensation in the quarter totaled $2.6 million. As Joel mentioned, we continue to demonstrate underlying operating leverage resulting from our focus on driving revenue growth while also effectively managing our operating expenses and gross margin. We plan to continue to focus on balancing these objectives as we drive towards cash flow breakeven. We now expect total operating expenses for 2025 to range between $94 million and $95 million, a slight increase at the lower end from our previous guidance range of $92 million to $95 million to reflect the increased expense in the third quarter related to sales overperformance and increasing variable compensation related to expenses we expect to incur by year-end. This range reflects 16% to 18% operating expense growth on a year-over-year basis and is well below our revenue growth rate. Included in our total full year expense is approximately $11 million in stock-based compensation, a non-cash expense. As we started last quarter and as part of an ongoing effort and commitment to provide increased transparency and support the ability to model our business, we will again break out and provide commentary on sales and marketing, research and development, and general and administrative components rather than referring to SG&A as a single line item. Sales and marketing expense was $12.6 million in the third quarter of 2025, up from $9.9 million in the prior year quarter and slightly up from $12 million in the second quarter of 2025. The year-over-year increase was largely due to personnel-related expenses associated with ongoing scaling of our commercial activities, investment in direct-to-consumer marketing, and other sales-related expenses. The slight sequential increase was primarily due to higher variable incentive compensation related to sales overperformance. We now expect sales and marketing expense to total between $47 million to $48 million for the full year 2025, slightly up from our previous guidance range, primarily driven by the aforementioned increase in variable compensation related to higher sales performance. R&D expense was $6.6 million in the third quarter of 2025, up from $5.8 million in the prior year quarter and slightly down compared to $6.8 million in the second quarter of 2025. The year-over-year increase was primarily driven by personnel-related expenses associated with the development of a next-generation platform, AI-enabled tools, and ongoing clinical trials. We now expect R&D expense to total approximately $28 million for the full year 2025 or at the higher end of the range of our prior guidance as investment in next-generation products continues, including final preparation of our IGE PMA supplement, which is still on track for submission by the end of this year. G&A expense was $4.6 million in the third quarter of 2025, an increase when compared to $4 million in the prior year quarter and down sequentially from $6.1 million in the second quarter of 2025. The year-over-year increase was primarily driven by personnel-related expenses. The larger sequential decrease was driven by nonrecurring costs associated with an executive transition in the second quarter. We now expect G&A expense to be at the lower end of our previously guided range and to come in at approximately $19 million for the full year 2025. Loss from operations was $2.6 million compared to a loss from operations of $4.2 million in the prior year and a loss of operations of $6.8 million in the second quarter of 2025. We recorded $1.6 million in interest expense compared to $2.2 million in the prior year quarter, reflecting the benefits of our debt refinancing earlier this year at more favorable terms. We continue to expect interest expense of approximately $8 million for the full year 2025. Regarding interest income, we expect approximately $2.5 million in income for the full year 2025. Net loss for the quarter was $3.5 million compared to a net loss of $5.5 million in the prior year period and a net loss of $8.7 million in the second quarter of 2025. Our free cash flow, defined as operating cash flow less capital expenditures, was negative $2 million in the third quarter of 2025 compared to negative $1.8 million in the third quarter of 2024. The year-over-year change primarily reflects higher revenue and gross margins, are partially offset by an increase in inventory as we place final orders for the DIXI product line. Lastly, as Joel mentioned previously, adjusted EBITDA, defined as EBITDA, excluding stock-based compensation, was a positive $0.1 million in the quarter compared to a negative $1.6 million in the third quarter of 2024 and negative $3.5 million in the second quarter of 2025. Finally, ending with our balance sheet, our cash and short-term investments balance as of September 30, 2025, was $60 million. We continue to believe this gives us sufficient capital to fund operations through cash flow breakeven. And with that, I would now like to turn the call back over to Joel for closing remarks.

Thank you, Patrick. The third quarter was a record quarter for NeuroPace and was driven by execution of our strategy and demonstrated strength across the business. We delivered record revenue, continued gross margin strength, and operating leverage, all of which demonstrate how our strategy and its execution are translating into results. At the same time, the broader field is recognizing what we've known for years, that responsive, data-driven neuromodulation represents the future of epilepsy care. We believe there is a growing view that the RNS system will serve as the foundation of the future standard in individualized brain neuromodulation. Multiple factors are beginning to converge that position RNS and NeuroPace to build on our current momentum. We have world-class opportunities, world-class technology, world-class data, and a world-class team to deliver on them. These foundational factors position us to establish RNS as the standard of care in epilepsy neuromodulation. Thank you for your time today and for your continued interest in NeuroPace. Operator, we'll now open the line for questions.

Your first question comes from Rohin Patel with JPMorgan.

Congrats on a good quarter here and strong RNS revenue growth. My first question is just on 2026 and your outlook. Trends seem to be progressing well on all fronts as we close out the year. So just as we look ahead, can you help us understand the preliminary thoughts on the growth outlook and specifically how you're thinking about RNS growth given DIXI revenues will be coming off? And what are some of the key assumptions embedded in the outlook for new indication launches and some of these AI applications driving utilization and also Project CARE in the community setting?

Hello, Rohin, thank you for your comments, and thanks for the question. This is Joel. So as we look forward to 2026, I think we're guiding here for '25 and for the quarter of Q4. So I'm not guiding formally for '26, but we do think that a lot of the fundamental factors that are in place position us really well for the upcoming year. We've been clear when we think and talk about our longer-range planning, the core of our focal epilepsy indicated business, the RNS driver for that focal epilepsy indicated business is a business we're confident in growing at 20% plus. We're doing that, and that really serves as the foundation for the business. And then we see the things that we're talking about here with regard to the key development initiatives, both our clinical development initiatives with IGE as well as pediatrics and then the positive effects that the R&D pipeline as well with regard to ease of use and efficiency in generating improved clinical outcomes. A lot of those things are coming together to add on to the top of that core of the 20% plus growth in the currently indicated business. So we're really pleased with Q3. We think that we're really well positioned. We've got a lot of stuff converging and coming together here. And we'll talk more about '26 when we talk about '26, but we think that gives us a strong foundation to build on that 20% plus.

Yes. I just wanted to add, and I really appreciate the question. We did provide a financial supplement so that the analysts, the entire street will get a very clear and transparent message in terms of what our historical revenue has been between DIXI and RNS. And I think what you're talking about is very key because we want to make sure that people understand that right now, there's still some DIXI revenue sitting in some people's 2026 numbers, and it's important that we really look at this on an RNS to RNS basis. So that was the basis of us giving that extra disclosure. And we would certainly expect that models will start reflecting that and show that likely 20% at a minimum growth for RNS.

Yes. So important point, Patrick, and I know you're up on it, Rohin. But with our prepared comments here, just emphasizing for folks that substantially all of the DIXI revenue will be complete here at the end of 2025. And so 2026 will be RNS and the RNS basis and the RNS growth should really be the focus of the model.

I have a follow-up. This looks like a long-term development for you. In your prepared remarks, you talked about the integration of your efforts in data, neuromodulation, and the hardware enhancements you have made or plan to implement over time. You also mentioned partnerships in drug development, like the Rapport collaboration, which utilizes your extensive EEG database and some AI capabilities to assist partners in drug development and biomarker identification. I understand it's still early, but can you share any initial feedback from your partners regarding how you see the platform aiding drug discovery or personalized medicine? Additionally, I know you mentioned about $700,000 in revenue, indicating early momentum. Are there specific milestones or indicators that investors should look for in the coming year, such as increased recurring revenue or other data points?

It's a great question, and thank you for emphasizing the topic. We do see that there are a number of things here that are really converging. And we are, we think, at a point of confluence here with regard to the data, the nature of some of the fields that are developing around us in terms of data science and then software as well as hardware development, as you mentioned. So I'll comment in a couple of different areas that you mentioned. One, from a partnerships perspective, I think you can go back and look at some of the public disclosures from Rapport that the ability to really provide that window into the brain and which we do both for our development partners within clinical study partnerships provide a tremendous amount of value as well as to clinicians every day in managing patients out there, which is why we're able to tailor and target therapy for individualized patients and demonstrate best-in-class results. That ability to uniquely monitor, record, analyze, and then tailor therapy is really at the foundation of both those partnerships as well as then what I was mentioning in terms of the journal focus where personalized, individualized targeted neuromodulation shows a tremendous amount of potential. And the ability to integrate that data and then tailor the delivered therapy is something that the RNS system is really uniquely well positioned to take advantage of. So we think both with regard to partnerships, more on the way there. I won't get into the specifics of it. But I think on the last call, we had mentioned UCB in addition to Rapport, and we are working on others as well from a partnership perspective. And then, again, just that ability to use data, some of which is data analysis that humans just aren't able to see the patterns in our unique set of tools, algorithms, and AI software is going to put us in a position to be able to leverage the unique nature of the RNS platform. So we're particularly encouraged about both the near-term results in the business as well as where the platform is positioned from a hardware, software, and data perspective as we see that confluence of factors.

Your next question comes from Priya Sachdeva from UBS Financial.

Congrats on a great quarter. I think first for me, would just love to parse out the implied growth for 4Q. The full year midpoint kind of implies a pretty steep step down despite pretty strong double-digit growth year-to-date and it seems to us like no slowing in momentum. So would just love to understand what you're seeing on the ground to help us give some context around that implied growth for 4Q? And then just a follow-up after.

Thank you, Priya. It's great to hear from you, and I appreciate your question. Let me start by addressing your point. What we're observing on the ground is very positive. As I noted in our prepared remarks, we’ve experienced strong execution and performance across the business. The primary growth drivers are the adoption and utilization in our Level 4 centers, which is where most of our business is currently focused. To break this down further, we've achieved all-time highs in prescribers, accounts, and utilization simultaneously. It's worth noting that achieving these three metrics together is quite challenging, especially when onboarding new customers and clinicians, who often start off more gradually than established clients. We value seeing all three metrics trending upwards simultaneously. Additionally, our commercial organization has demonstrated excellent execution. As I mentioned, all of our sales regions have exceeded their planned sales levels, showcasing the consistency of our enhanced team’s performance. This includes the contributions from both care and direct-to-consumer (DTC) efforts. Regarding Q4, to address your question, a few factors are at play. One area to highlight is RNS, and we’ll discuss that soon. Specifically, DIXI is expected to decrease, which we anticipate due to the winding down of the business. This represents the most significant impact on our previous expectations and accounts for some of the dynamics we foresee in Q4. That said, looking at RNS for Q4, while I’m not providing guidance beyond what we’ve already shared, I can say that the RNS business has had a solid start in October and throughout the quarter, both in terms of execution and our patient pipeline. We’re feeling very positive about this, although there is some uncertainty and downside due to DIXI. Now, I’ll ask Patrick to share more on some of the factors influencing our outlook.

Yes. Thanks, Joel. And I think Joel hit the nail on the head there. Look, we had a very strong quarter, and we really do try to look at this business in 6-month increments, and Joel has been very consistent prior to me coming here. And if you look at even at the midpoint, as I said in my prepared comments, once again, DIXI is the reason why the overall number didn't go up as much as it did, and we talked about why that is. Let's focus on RNS. RNS in the first half of the year grew 21%. And at the midpoint of our implied guidance of Q4 for RNS of $20 million to $21 million, we're going to grow 23% in the second half of the year at that midpoint. And so we feel very comfortable with the durability of this business and where we're moving as we go forward, and Joel already hit it. We're off to a good start in Q4 with October, but that's really the components of it. So a strong quarter overall.

I mean just a follow-up, great to hear the news on the PMA submission. And now that we have some increased clarity on the potential expansion, could you just remind us on the plan of attack into potential approval and how quickly we could see some incremental growth contribution? Congrats on a great quarter.

Thank you. Our plan specifically concerns NAUTILUS in the idiopathic generalized epilepsy population. We aim to submit the PMA supplement by the end of 2025, anticipating a typical 180-day review period for a PMA supplement, which would target mid-2026 for potential approval. We believe we are on track for this timeline. While each process can vary, we are confident about submitting before the year ends and starting the review clock for mid-2026.

Your next question comes from the line of Mike Kratky with Leerink Partners.

Congrats on a great quarter. To start, let me just say I'm immensely grateful for all the additional disclosures you're providing moving forward. So massively appreciate that. Really impressive RNS growth this quarter. I guess to follow-up on a prior question, it looks like the implied 4Q guidance for gross margin might also be implying a bit of a step down. So especially if DIXI might be a little bit lighter than anticipated, how should we reconcile some of your commentary just on the RNS strength with the implied step down in gross margin? I would have probably thought that would have been a little bit higher as RNS ticks up as a percent of revenue.

Yes. This is Patrick here. Fair question, Mike, and good to have you back on the call. Look, I would say that, as we said in our prepared comments, we continue to believe that RNS will be north of 80%. 80% is a minimum bar for us. And I would just chalk it up as us not wanting to get ahead of ourselves. There is some movement in DIXI. We did say approximately $3 million. Is there a chance we sell more than $3 million as we're exiting the business? Potentially, and that could obviously have a drag on the overall gross margin. So I would really just view it as more of a mix issue related to DIXI as opposed to anything else. I will be very clear again, as I said in my prepared comments, as we move into 2026 and we are an RNS business, you should be modeling a gross margin that's 80% at a minimum, and we'll provide additional color when we officially guide 2026. And then we had a good question on service revenue, so I might as well hit that real quick. Look, service revenue has very good margins for us. And I think the key there for everyone is we will come back to you when we see additional potential service revenue streams that we have. But rest assured, we will be looking to optimize and maximize as best we can the monetization of our really good data and how we can support some of these pharma collaborations.

And maybe just one follow-up. I really appreciate the color on Seizure ID. Can you just talk about how that fits into your broader portfolio? And is that something that you expect to generate revenue or will be more of a support tool moving forward?

Thanks for that, Mike. Yes, we're excited about Seizure ID. And as I mentioned, it's the first in what we expect to be a suite of tools that we'll be leveraging our proprietary EEG data and then AI-based algorithms that we've developed internally as well. So what we expect from Seizure ID is to make it more efficient and easy for clinicians to be able to identify episodes that are long episodes and the areas that they want to look at most closely for therapy and for changes in therapy to continue to improve outcomes. So the reason that matters is that for some patients, these cycles of particularly important EEG information are complex enough or occur over a long enough period of time that regardless, and we have tremendously talented and dedicated customers, a human can't pick them out if those cycles are coming over sometimes weeks or months of a period of time. And so when they look at that information and when Seizure ID looks at that information, it can very efficiently and effectively pick out those hallmark EEG patterns and make it easier for them to identify the areas of interest and then tailor therapy along with that. And so again, efficiency and ease of use leading to improved clinical outcomes is the focus of that particular tool. And the way we see that adding value in the business is through increased numbers of patients having access to an improved therapy causing us to both be able to compete with other treatment approaches as well as make RNS more easily accessible for people to have more RNS patients in their practice. So it's really all about making RNS more accessible and the improvements associated with it more accessible. And that's how everybody will see value from Seizure ID.

Your next question comes from the line of Vik Chopra with Wells Fargo.

This is Simran on for Vik. Maybe just to start off on the margin commentary, very helpful color. I guess I just want to clarify, should we be thinking about 80% gross margin as a baseline for 2026? And are there any additional puts and takes that we should consider on the margin line going forward?

Eighty percent is a fair number to model. RNS has been running ahead of that. The only caveat I would put is if there's some trickling DIXI revenue that happens in Q1. But again, as I said, the wind-down period does officially end Q1 of 2026, but we plan to be substantially done with sales. But again, I think modeling an 80% would be very fair from that standpoint going forward.

And then maybe just on NAUTILUS. I appreciate your reiteration of the timelines there. But when can we expect to see the full data set from NAUTILUS publicly?

So there are a couple of different opportunities for us to get the data out with NAUTILUS. We do expect to have a poster abstract presented at AES, and we are also planning on submitting for a presentation at AAN next spring as well. So a couple of different opportunities there, and we're looking forward to talking to people about the updated data.

Your next question comes from the line of Frank Takkinen with Lake Street Capital Markets.

Congratulations on a great quarter. I was wondering if we could discuss the NAUTILUS data and the industry's awareness of it. I understand that it's not something you can market or discuss directly, but we've encountered the concept of off-label use in our talks with physicians. I'm curious if this might have contributed to the quarter, with doctors possibly using it more off-label and having some clinical data to back that up.

In the past, we have mentioned that investigators are the only ones familiar with detailed data beyond what has been shared publicly. Regarding business performance in the quarter, I don't believe there was anything unusual, nor was there any variation in medical practice that would have been influenced by the NAUTILUS results or the IGE data. As previously noted, we received positive feedback from investigators about the safety data and the prespecified secondary endpoints. We were pleased to hear this from the investigator community, but nothing else was unusual in the quarter.

Yes. I would echo that. And remember, we have a little bit of a long, let's call it, "clinical sales cycle" here, right? It takes a little bit of time for a patient once they get into a Level 4 and then that journey that they go through, right? So I think the most exciting thing that we're looking forward to is that when we submit and potentially get that IGE approval, the ability to put the entire organization behind that and be able to speak openly to doctors, obviously, and talk through that and being able to do both focal and IGE in the adult population is going to be a huge win for us. And some people would say 1 plus 1 may equal more than 2 when this is all done. So I think that awareness and our ability to support it is going to be a key tailwind as we move through 2026 and beyond.

And with our last question, the question comes from Paige Chamberlain with Wolfe Research.

I'm hoping to get some quantification around your market expansion efforts through Project CARE. I see a couple of goals you guys have laid out around this initiative. I want to ask you guys on 2. So first, I see the target of expanding your reach to an additional 1,800 epileptologists. I'm just wondering, benchmark how many of those have you reached so far and maybe just a general timeline and vision for that. The second one I see is to more than double the number of implants and referrals coming from CARE accounts in 2025. Curious the starting point for that going into 2025 and perhaps now sitting in November, are you on track to double?

Thank you for the question. Regarding our goal to double in 2025, we are using 2024 as our baseline and are pleased with our progress for 2025. Our plans for CARE this year are on track. We've identified that the target group of 1,800 epileptologists is the right number. We are employing a targeted approach to reach them, focusing first on Level 3 centers and community centers that have the necessary capabilities, including functional neurosurgeons, patient populations, and administrative support. We are in the early stages of penetrating this group and are encouraged by the initial results, but we know we have a long way to go with the entire group of 1,800. We are optimistic about our trajectory and believe CARE will be a significant long-term strategy for us, especially as we expand into IGE. We monitor our metrics internally and while we haven’t discussed them quarterly externally, we will consider doing so. Importantly, we've seen an increase in prescribers and utilization this quarter, which is very encouraging. CARE is a key factor in this growth. Looking ahead, we anticipate that we will greatly benefit from any additional indications. However, we also have significant potential with our adult focal epilepsy market, which is why we remain confident in our ability to grow the RNS platform by at least 20% for the foreseeable future.

I'll sneak in one more, if I may. I echo the appreciation for the additional disclosure around DIXI and service revenue lines. I guess I'll test my luck to see if we can get the same incremental detail around replacement. I know you guys obviously don't break that out. But the trough sort of for this revenue line has been described as this year, earlier this year, we're all doing our best to stab at this number. I'm just wondering if, directionally, you can nudge me should we be thinking about replacement revenue going north from here?

Yes. We are primarily focused on our initial implants for now. Eventually, we expect to see a greater contribution from replacements, similar to other neuromodulation devices that derive a significant portion of their revenue from replacements. Currently, our replacement revenue is quite small, less than 10%, and at times even in the mid-single digits, depending on the quarter. We have projections for when replacements might increase, but we're still some time away from seeing a substantial cycle, especially given the number of meaningful units placed over the last two to three years. We are looking forward to that time, but for now, it makes sense to focus on modeling initial implants, and we will share more information as the replacement aspect becomes more significant.

Thank you. And with no further questions in queue, I'd like to turn the conference back over to Joel Becker for any closing remarks.

Thank you very much. We're pleased with the performance in the quarter and the direction and trajectory of the business. And as I mentioned in my prepared comments, we believe that there are multiple factors that are beginning to converge here, both with the results that we see as well as the way RNS is positioned and NeuroPace is positioned to build on that momentum. We have world-class opportunities, world-class technology, world-class data, and we've got a world-class team in place to deliver on them. And these foundational factors are exciting for us and position RNS and NeuroPace in a position to really establish ourselves as the standard of care in epilepsy neuromodulation. I'd like to thank all of the members of the NeuroPace team for their ongoing tireless efforts to advance our mission. And thank you all for your time today and for your continued interest in NeuroPace.

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