Thank you, John. Good day, everyone, and thank you for joining us for our fourth quarter and full-year 2024 earnings call. 2024 was a transformative year for Nyxoah with tremendous progress made throughout the year. We are extremely well positioned to bring Genio to market in the U.S. by the end of this month. We have proven that Genio can deliver best-in-class outcomes for obstructive sleep apnea patients. Our pivotal study, DREAM, met both its primary and secondary endpoints. The DREAM study demonstrated a strong AHI responder rate of 63.5% and an ODI responder rate of 71.3% with an overall median AHI reduction of 70.8%. Importantly, through the study, we demonstrated that Genio is the only therapy with explicit clinical evidence-based data proving its ability to maintain its efficacy irrespective of a patient's sleeping position. This is a critical differentiator as people sleep on average between 35% to 40% of the night on their back. And based on published data, the number of times per hour that the patient stops breathing can double while in a supine position. Genio stands alone with clinical trial data, specifically validating this claim, making it the most consistently effective solution for patients throughout the entire night of their sleep. While our DREAM study uniquely requires the minimum of 60 minutes of supine sleep time, on average, all subjects slept 140 minutes in a supine position. The study measures position-specific outcomes and demonstrated a 66.6% median AHI reduction while sleeping in a supine position despite the fact that the number of airway obstructions can double in this position. This reduction compares favorably to the 71% median reduction shown while sleeping in a non-supine position. This consistent efficacy across sleep positions makes Genio the most effective solution for patients throughout the entire night of sleep. Unlike competing technologies where supine sleep efficacy data has not been disclosed. Additionally, on DREAM data revealed another significant clinical advantage. Genio produces a remarkable percentage of what we refer to as super responders, patients whose AHI score is dropping below 15, effectively returning their mortality and cardiovascular risk to levels comparable to individuals not suffering from OSA. 82% of all DREAM subjects achieved this result. This represents a profound clinical impact that goes beyond symptom management to potentially extending patient lives. The combination of the supine and super responder data makes Genio a differentiated and unique solution for patients with OSA. In addition to the strong efficacy results, Genio also demonstrated a favorable safety profile with an 8.7% severe adverse event rate. We believe that this efficacy and safety profile will have a positive impact on therapy selection by physicians and therapy acceptance by patients compared to the current available HGNS solution. Let me now switch to the regulatory perspective. We have submitted the fourth and final module of our PMA submission in June '24. We continue to have a very interactive dialogue with the FDA and have successfully completed the remaining requirements, including this Belgium site visit, which has previously been delayed due to circumstances unrelated to Nyxoah. Based on our current interactions with FDA, where the focus is now on labeling, we continue to expect to receive FDA approval by the end of March of 2025. In preparation for U.S. commercial launch, we have built a world-class team in support of our U.S. go-to-market strategy and commercial readiness plan. Notably, I moved with a family to the U.S. to be underground during this critical period. In addition, we have built our U.S.-based senior management team, including hiring John Landry as Chief Financial Officer; Dr. Maurits Boon as Chief Medical Officer; and Scott Holstine as Chief Commercial Officer. In addition, we have industry-leading talent in place with a track record in OSA and of neuromodulation across our sales, marketing, reimbursement and medical affairs in the U.S. Our strategy for penetrating the U.S. market revolves around two-pronged approaches. First, as a smart follow-up, we will target high volume HGNS implanting centers where physicians and patients are actively seeking an alternative solution to current therapy. In addition to these patients, we have also identified significant demand from patients who are hesitant about receiving a pacemaker-like implant for OSA and whose physicians have been eagerly awaiting a compelling alternative to offer them. Importantly, as a result of our clinical trials in the U.S., there are already 75 physicians that have been trained on the Genio technology and are familiar with its unique features and patient outcomes. Second, through focused commercial investments, we will develop strong referral networks with sleep physicians who manage a large population of moderate to severe OSA patients where HGNS is not yet fully embedded in their treatment pathway. As a company that prioritizes clinical evidence and patient outcomes, or simplified marketing messages, we believe in setting realistic expectations and partnering with physicians to find the optimal treatment for each patient as this is part of our mission in putting the patients first. We plan to launch in the U.S. with 50 commercial team members, comprising sales, marketing and market access professionals, who are currently all hired and trained with plans to scale quarter-after-quarter. This team will be supported by focused direct-to-consumer initiatives and dedicated reimbursement support. Regarding reimbursement, we have identified an established CPT code that we plan to utilize at launch. The CPT code, to be very precise, is 64568. This CPT code has been recognized by commercial and government payers for OSA indication and is the same CPT code used for the current FDA-approved HGNS technology. We expect this will allow us to align on pricing while we are differentiating on our unique technology and clinical outcomes. We are working closely with the American Academy of Otolaryngology and participating in the FDA's early payer feedback program to educate CMS and major commercial payers on Genio on the impact it can have on their patients. While our primary focus as a company has been on preparing for the U.S. launch, we also continue to be encouraged by our growth and what we learned in Europe. Our commercial proof-of-concept in Germany has provided valuable insights that we are actively incorporating into our U.S. launch strategy. Our growth in Europe was primarily driven by the continued execution of our commercial strategy in Germany. As John will detail in his remarks, we are now recording a portion of our disposable patch revenue as deferred revenue. Our revenue would have been €1.9 million in the fourth quarter of '24, excluding the impact of this deferral. This represents a 46% sequential growth over Q3 2024. For the full year, we have delivered revenue of €5.1 million and an 18% increase over 2023. We have also continued to expand our geographic footprint in the region. In December, we launched Genio in the United Kingdom. The Genio system is covered under the NHS Specialized Service Device program, which makes us believe that the U.K. has the potential to become one of our largest international markets. Based on the first successful implant at University College of London Hospital, there was a lot of excitement created from Genio in the U.K., and we look forward to further expanding into other hospitals across the country and scaling our sales force. In addition, we have launched in the United Arab Emirates with the first commercial implant done in Dubai's German Saudi Hospital. This represents a unique milestone as Genio was the first HGNS implant performed in the Middle East. Collectively, all of our accomplishments in 2024 brought us at this point. We are now on the verge of bringing a truly innovative OSA solution to the U.S. market where there still exists a massive patient population in need of treatment that can benefit from our Genio solution. Both we and the clinical community are incredibly excited about what the rest of 2025 has in store.

Thank you, Olivier. As Olivier mentioned in his earlier remarks, we deferred revenue related to disposable patches in the fourth quarter of 2024. As part of our contracts with customers, we deliver additional disposable patches on top of those included in the initial delivery of a Genio system. Beginning in the fourth quarter, the portion of the selling price for a Genio system related to these additional disposable patches will be recognized as deferred revenue. This deferred revenue will be recognized as revenue over time as the disposable patches are delivered to the customer. We recorded deferred revenue of €600,000 in the fourth quarter of 2024. Recognized revenue was €1.3 million in the fourth quarter and €4.5 million for the full year 2024. Total operating loss for the fourth quarter of 2024 was €18.3 million versus €10.8 million in the fourth quarter of 2023, driven by the acceleration of the company's R&D spending, ongoing commercial and clinical activities and an acceleration in commercial investments in the U.S. Cash position remained strong at €85.6 million at December 31, 2024, compared to €57.7 million at the end of 2023. This includes proceeds from our €24.6 million ATM equity raise early in the fourth quarter and reflects our disciplined approach to managing cash burn as we prepare for FDA approval and U.S. commercialization. With that, I would now like to hand the call back to Olivier to discuss his thoughts on 2025.

Thank you. Before we conclude, I want to emphasize that this is truly an exciting time for Nyxoah. With all of the fantastic work by our organization during '24, we are incredibly well positioned for the future. Looking ahead to 2025, the U.S. will be our key focus. Based on our current interaction with the FDA, where the focus is now on labeling, we continue to expect to receive FDA approval later this month or by the end of March in 2025. We have been able to identify a CPT code well known by payers in the OSA indication, which will allow us to establish competitive pricing compared to the current FDA-approved HGNS technology. Second, we hired and trained a U.S. commercial team that is ready to launch upon FDA approval with a two-pronged strategy, acting as a smart follower focused on high-volume HGNS sites in combination with focused commercial investments in developing referral networks for sleep physicians who manage a large population of OSA patients. Our success will be measured in entering these new accounts and driving new patients to Genio coming from this referral network, ultimately resulting in market share gains. Lastly, in international markets, we will further increase Genio's penetration within Germany but also within the U.K., and we will selectively expand into new targeted international geographies such as the UAE. 2025 will be a transformative year in Nyxoah's growth as we make significant progress towards our mission of making sleep simple by bringing the Genio solution to OSA patients in the U.S. and further expand internationally. With that, I would now like to open the lines for Q&A.

Thank you. Our first question comes from Adam Maeder with Piper Sandler. Your line is open.

Hi, good morning, Olivier and John, thank you for taking the questions. And great to hear you still expect approval here by the end of the month. A lot of different questions that I could ask here, but maybe just to start. Reimbursement, new update there. You said you're going to use the 64568 Code. There is some investor consternation that, that level of reimbursement associated with the code is not overly attractive or sufficient for hypoglossal nerve stimulation, in particular, to the physician. So what's your response to that? And do you believe this coding strategy is sufficient to drive strong uptake of Genio? And then I have a follow-up. Thanks.

Thank you, Adam. I agree that from the perspective of physician fees, this code is not the strongest. However, looking at Nyxoah and our market entry, it's crucial for us to secure a CPT code that facilitates payment for our technology. We're very pleased to have identified a code, as this was a key topic in our preparations for the U.S. launch. That said, there is still significant work needed in this area to improve the coding and enhance pricing attractiveness for physicians. Additionally, we will explore ways to highlight the unique aspects of the Genio technology, especially in terms of bilateral versus unilateral stimulation, to further differentiate our product. In summary, we're happy to have a code, and it's important to note that this same code applies to both the existing HGNS technology and the upcoming Genio technology.

Understood. And really helpful color there. Thanks, Olivier. For the follow-up, maybe just one on how you're thinking about the trajectory of U.S. launch. I'll ask the question kind of this way. So I think I heard you mention 75 docs. I think those are U.S. docs are trained on the Genio technology already. How do we think about the pace of new account openings this year? I know the strategy is concentrated deep, not wide. But just, is there a target number in mind for 2025? Just help us understand the strategy there? Thank you.

First of all, when we are talking about 75, it's a little bit more than 75. All physicians were part of the clinical study, DREAM, ACCESS and also the usability study we did. And I think what was enormously rewarding for us was hearing that all physicians are actively asking and reaching out when it will be available and that they want to have Genio integrated in their treatment for how to treat OSA patients. That's the first step. Second one is, as I mentioned, we have 50 added sales team members that are currently fully trained and ready to launch. So now how will we approach this? You remember that the current HGNS business is very concentrated with roughly 300 to 350 sites representing, let's say, 70% to 75% of total HGNS revenue. So those will be the targeted accounts, the 300 to 350. With the 50 people, we will start, we will train and educate our surgeons. Every quarter we'll further scale up and we also have a playbook for scalability in adding additional sales reps quarter-after-quarter. So our first challenge will be, let's get the first physicians trained, then we start expanding quarter-after-quarter. And I do think that in a period of 12 to 18 months, we will be able to cover all those Tier 1 high volume HGNS accounts.

Very helpful. Thank you.

Thank you. Please stand by for our next question. Our next question comes from the line of Jon Block with Stifel. Your line is open.

Great. Thanks guys and good morning. Olivier, it seems that the dialogue with the FDA, per your comments, has been consistent and thorough. However, just when I look at the calendar, and the end of March is relatively soon, we hear about all these cuts at the agency that are taking place. So maybe if you can give us a little bit more color on why still the confidence by the end of this month, the end of March? And then maybe even more importantly, what are your thoughts for the label? Because again, it seems like you're in the final stages, your thoughts for the label and the likelihood that those supplying claims that you talked about are included upon approval? And then I'll ask my follow-up? Thanks.

Well, thank you, Jon, for the question. And first of all, indeed, it has been very challenging times for government and lately. Now when it comes to our file and the review, I am pleased, and I say very carefully when I'm saying this, but I'm pleased that so far, we have not seen any negative impact of the ongoing political changes that are impacting the government procedures. So that is already one step. So from that end, we are still good. Now over the last weeks, it has been extremely interactive with the FDA going back and forth, closing and answering the last questions and also entering the labeling discussion. So when you talk about timing and why we still feel confident by the end of this month, I think I mentioned earlier that there is something like a 90-day clock, and the 90-day clock is ending as of this month. So that's why we are still confident with no changes in our review, but entering the last stage with the labeling discussion and also knowing that the clock is ticking, that it makes sense to still say that we expect to have an approval by the end of this month. That is hopefully answering the first part of the question. On the second one, more specific on the labeling. I mean it's clear that we would like to have also the uniqueness with our supine data being reflected in the label. And that is also the part that we presented to the FDA. It also has to be clear that with our existing clinical evidence of CCC patients and also the work that we are seeing in the U.S. in the ACCESS study that we also do not see any reason to have CCC as a contraindication as compared to the current available HGNS technology that has CCC as a contraindication. We do feel strong that this will not be the case. But maybe conclusion, I do not want to jump to any conclusions until FDA makes up its final remarks. But in our label discussion, to answer your questions, those are two things that we are currently actively discussing.

That was great. That was great color. Thank you. And then second question, sort of follows-up on where Adam was going, maybe from a little bit of a different perspective. Just on that ramp or on the trajectory, how do we think about the commercial payers coming on board? Do you feel confident you have at least one here in 2025? Do you have a handful? And do you need some of these studies peer-reviewed to help sort of stimulate or move that process forward?

Yes. So first of all, and I mentioned this already a couple of times, our competitor has done a terrific job educating commercial payers about the benefits of HGNS. And sometimes, it's nice to be second. I mean I can only compliment and applaud this. Now, when it comes to our strategy, also here, we will work with pre-authorizations. We will have already patients lined up, and we will have a lot of prioritization in place the moment we have FDA approval and moving forward. We do think it's fairly realistic to expect the first commercial payers during quarter three, quarter four this year. And of course, next to them, we have the government payers like CMS, Medicare, where we do expect to have payments right from the beginning.

Thanks, guys.

Thank you, Jon.

Please stand by for our next question. Our next question comes from the line of Ross Osborn with Cantor Fitzgerald. Your line is open.

Hey guys. This is Matthew Park on for Ross today. Thanks for taking the questions. I guess just to start off, can you walk us through any manufacturing supply chain that you guys currently have in place? And do you think it's sufficient to meet existing demand upon approval?

Yes. Well, thank you for the question. And you're pointing out such an important question. I mean this is what every company wants to have when you launch; you need to make sure you have product and you have sufficient manufacturing and inventory available. So also for Nyxoah, this is one of our key points that the team has worked so hard. And I'm happy to say that also there, we feel really confident. One more topic, what I also would like to point out is that we are manufacturing products for the U.S. market also in the U.S. This was a decision that was made already a couple of years ago. And I think I see also in the current landscape that this was also the right decision. So not only we have significant inventory; we also do not have to ship inventory around the globe. It is manufactured in the U.S. for the U.S., also being part of our U.S. focus as a company that we are having.

Got it. That's very helpful. I have one more question that relates to what Jon mentioned earlier. Do you expect to need any real-world data after approval? What might the timelines look like to facilitate additional adoption? Thank you for addressing my question.

My apologies, but first, you were not clear in the first part of the question. We had a bad line. Can you please repeat?

Would you anticipate needing to generate any real-world data upon approval? And what would any potential timelines for this look like?

Yes. Yes. John? Yes.

Yes. I think we'll probably continue. This is John here. As we move forward, we will definitely want to collect real-world data and experiences so that we can better explain the clinical and economic justification of our technology. Thus, this will be an important part of our process going forward.

I apologize, but I had trouble understanding the question. However, as part of the PMS post-market study approval, we intend to begin collecting real-world data once we launch. So yes, this is definitely our plan.

Got it. That's super helpful. Thanks guys.

Thank you.

Thank you. Please stand by for our next question. Our next question comes from the line of Suraj Kalia with Oppenheimer & Company. Your line is open.

Hey, Olivier and John, congrats on all the progress. Can you hear me all right?

Yes, I can.

Perfect. Olivier, you have significant experience in Germany. As you prepare for the U.S. launch, regarding the 75 doctors you are targeting, what insights from Germany do you think are most relevant? What do you see as the main appeal of Genio compared to Inspire? Is it the difference between supine and non-supine, or the bilateral aspect? Are physicians looking to diversify, or is it tied to your CCC approach? Please clarify what you believe will attract these initial 75 physicians.

Yes, thank you for this question. So going back to Germany and our initial learnings, offering physicians and patients a choice in HGNS implants and stepping away from an invasive pacemaker solution into a single incision procedure has been key in the first introduction with the technology. Then, of course, we explore product differentiation. They see the benefits from bilateral stimulation. They also see the uniqueness with patients in order to upgrade their system without the need for any surgery and also, of course, avoiding the risk for another surgery for the placement of a battery. And that's what we saw initially. While we are further scaling in Germany and learning, we're also seeing that physicians more and more also tend to understand how important it is that patients are very compliant with their technology. And also there, we are seeing that with our available component, that creates a habit of before you go to that, having your wearable ready to get a good night sleep, expressed in a compliance ratio of more than 85%. This is also something that is driving the physician next to the results that we are seeing in treating this and to continue to choose Genio.

Got it. Got it. And as my follow-up, Olivier, maybe I missed it in your prepared remarks. Any update on timing of DREAM publication and also status of enrollment in ACCESS, gentlemen? Thank you for taking my questions.

Yes. And that's an excellent question on the DREAM publication. So submission has been made. It's currently under review, and we expect publication in a leading medical journal. We expect this publication in the coming months. I mean we cannot define how fast the review process is going, but the submission has been done and then we really expect to have it out definitely before summer. When it comes to ACCESS. So there, we continue to make good progress. We will not disclose the precise number, I think we never did this, but we do expect to complete enrollment by mid-'25. And then the next steps, as you know very well which will be a PMA supplement. And after this, therefore, we expect that we will have late '26, beginning '27 of potential label expansion.

Thank you. Our final question comes from David Rescott with Baird. Your line is open.

Thank you for taking my questions. Olivier, could you elaborate on your confidence regarding the March approval timeline and the 90-day period mentioned? First, I want to confirm that you indicated the Belgium site is indeed operational. Additionally, do you have any events planned between now and April? If we reach April 1 without any press release from the team about the approval, what might you speculate could have caused a delay in meeting that timeframe? I'm trying to anticipate potential questions that could arise in the coming weeks.

Yes. First of all, David, we are still planning to have a press release out before the end of March. There is a 10-day grace period that the FDA has, but we have no indication that this would apply to us. So we remain confident that before the end of March, we will have more communication. If we do not have any further news, I think it's highly unlikely for us. In conclusion, we remain confident. There is a grace period in place, and there are no indicators pointing in that direction. So, my short answer is that I do expect to have a significant update by April 1.

Okay. Very helpful. Regarding reimbursement, I heard your comments about the code you plan to use. Can you help us understand how you are assessing the potential opportunity for patients eligible for Medicare reimbursement compared to those who might be eligible when you expand commercial coverage? As you consider the rollout starting on day one, do you have any visibility from CMS indicating they will accept that code for your device? Do you anticipate any challenges during the initial rollout regarding the prior authorization process for coverage? Or do you expect that for most of 2025, the prior approval process will be relatively straightforward with this code? Alternatively, do you think there might be initial hurdles that could complicate adoption and reimbursement, pushing easier approval toward the second half of the year? Thank you.

So I do think we can state that roughly 20% to 30% of payment is done by Medicare, specifically related to OSA patients also knowing the average age. On the other hand, we know that there are local decisions that need to be made. And then we also asked and we are updating also the local mix due to using the FDA early payer program. No, we do not have the full influence on how fast things will go or I could not really comment in detail from a commercial payer perspective? How fast prior authorization process is going? And who will be the first picking it up? But I hope you will agree as well that when there is an established CPT code that they recognize for OSA payment, and since we fall under this code, if you look at the technicalities of our product, we do feel very confident that this will happen quite fast. And we continue working closely with the AAO on supporting us. And of course, the education to the early payer program is definitely also helping us.

Okay, thank you.

Thank you. Our next question comes from Paige Chamberlain with Wolfe Research. Your line is open.

Hi, good morning guys. This is Paige on for Mike Polark. First question, on the code, CPT code 64568, the description, we believe includes pulse generator. So that's obviously different than Genio form factor. Why are you guys confident that Genio fits into this code category?

Because we do have a pulse generator. I mean you need to have a battery. And the only difference is that we have an external pulse generator. And with pacemaker, we have an internal pulse generator. And to your point, as you mentioned, very precise, the code applies to both systems.

Awesome. Thank you. And then just one quick follow-up on the deferred revenue recognition change. Can you guys help us understand what portion of a new patient implant will be deferred in the future? And then does this mean that the patient needs to be compliant and use the patches over the period of use to be able to record the deferred revenue down the line? Thank you so much.

Yes. Thank you, Paige. So, in terms of the percentage, it's a small percentage of the total selling price of the Genio implant. So this is a small percentage that we'll be deferring over time at this point. And that percentage will continue to decrease over time for a couple of reasons. The cost and the ascribed value of the disposal patches decreased, they'll reduce the amount of the deferral that we have going forward. And then, in terms of compliance, there's no specific compliance requirements associated with the deferred revenue. So the deferred revenue will be recorded and recognized as revenue as the patient utilizes the devices and we ship the devices out to the patients. But there is no requirement for some sort of compliance metric similar to CPAP usage.

Thank you. Ladies and gentlemen, I'm showing no further questions in the queue. That concludes today's conference call. Thank you for your participation. You may now disconnect.
