Thank you, Brecht. Good day, everyone, and thank you for joining us for our second quarter 2026 earnings call.

Let me start with Q2 highlights. Q2 was a strong quarter for Nyxoah across multiple fronts, and I'm pleased with the progress we are making in the business.

First, the strong commercial execution of our US launch delivered the second consecutive quarter of more than 20% sequential US revenue growth. US net revenue was €5.2 million, up 22% over the first quarter of 2026.

We also posted another strong quarter of revenue growth in our international business, up 19% over the first quarter of 2026. On a worldwide basis, net revenue was €7.7 million in the second quarter, representing 21% sequential growth over the first quarter.

Second, before doing a deeper dive on the US commercialization results, let me provide our high-level leading US commercial indicators. Our US leading commercial indicators continued to strengthen across the board.

Entering quarter two with 40 fully trained sales reps, we can cover 200 of the top 400 high-volume hypoglossal nerve stimulation accounts in the US. We have trained 55 new surgeons and activated 89 new accounts in this quarter, doubling our active account base to 180.

We entered the third quarter with 427 patients actively under prior authorization, a 77% increase over the prior quarter. Our prior authorization approval rate remains at 100% for both commercial payers and patients submitted via the WISER Program.

On the reimbursement front, CMS announced meaningful proposed increases for HGNS overall, including Genio specifically. CMS proposed facility reimbursement would increase OPPS facility payment by 12% and ASC, ambulatory surgical center, by 15% for 2027.

These increases would further strengthen the economic value of the Genio procedure for the facilities. From a financing perspective, we significantly strengthened our balance sheet by securing $110 million during the quarter, taking away the financial overhang.

This new capital will provide us with the resources needed to further accelerate Genio US commercialization ramp and implement growth initiatives focused on increasing the patient funnel. Now digging in deeper into the US commercialization: the US commercial launch remains the primary driver of our long-term company success.

Our US focus strategy remains unchanged and centered on driving strong Genio adoption in the top 400 high-volume HGNS accounts, which represent approximately 70% of the total US HGNS volume. We hired and trained 15 new sales reps in the first quarter, bringing us to 40 sales territories as of April 1st.

Entering Q2, we had access to 200 of the top 400 high-volume HGNS accounts. Specifically, we trained 55 new surgeons in Q2, bringing the total to 262 surgeons trained on the Genio system.

We activated 89 new accounts in Q2, roughly doubling our active account base, bringing the total to 180 active high-volume HGNS accounts. Finally, we had 427 patients actively under prior authorization submissions entering the third quarter of 2026.

This is a 77% increase over the previous quarter. Doubling our active account base to 180 high-volume HGNS accounts in a single quarter demonstrates that both facilities and physicians are embracing Genio, and confirms the success of our patient referral pathway by sleep physicians.

With 427 patients actively under prior authorization exiting Q2, this gives us firsthand confirmation of increased patient demand and is a key leading indicator for Q3 of the acceleration of our patient pipeline, giving us confidence in continued launch momentum entering Q3. Next, reimbursement: there is now full clarity for Genio reimbursement with the dedicated Medicare C-code, C8011, for Genio.

Our commercial payer coverage remains broad and stable using existing CPT codes, and our market access team continues to execute strong on supporting prior authorization submissions. Through our Genio Access Program, we continue to see 100% approval rates of commercial payers, Medicare Advantage, and Medicare patients under the WISER Program.

Commercial payers are still the majority of our business, making up approximately 85% of it. The recent direction of CMS proposed rule for 2027 HGNS reimbursement would positively impact the clinical and economic value of the Genio procedure in OPPS and ASCs.

Specifically, CMS is proposing to increase hospital outpatient reimbursement for the Genio procedure under C-code C8011 from $31,526 to $35,414, or an increase of approximately 12%. CMS is also proposing to increase ambulatory surgical centers, the ASCs, reimbursement from $27,563 to $31,722, or an increase of approximately 15%.

These proposed increases are amongst the strongest within APC 5465, the Level 5 Neurostimulation category. Finally, in the upcoming September CPT Editorial Panel meeting, AAO-HNS, supported by Nyxoah as an industry member, will continue the discussion of a comprehensive HGNS coding.

As a consequence, Nyxoah did not submit Genio for a dedicated Category I CPT code on the September CPT Editorial Panel meeting agenda. Let me now focus a little bit more on our recent Investor Day.

On July 8th, we had the pleasure of hosting our Investor Day, where we focused on bringing together leading ENT surgeons and sleep physicians alongside independent reimbursement experts. The surgeons shared their firsthand implant experience with Genio, and both surgeons and sleep physicians confirmed strong airway openings on activation.

These real-time experiences are the key drivers behind Genio's adoption in their practice. The reimbursement experts presented their view of the HGNS reimbursement landscape, confirming the durability of long-term coverage and Genio's strong positioning under every future coding scenario.

The event reinforced the two pillars of our US launch: growing physician adoption and a solid reimbursement foundation. For those who missed it, the replay is available on our Investor Relations website.

International: before turning to the financial, let's look at the international markets. We accelerated revenue in the second quarter, resulting in a 19% growth quarter-over-quarter.

Overall, in the first half of 2026, we almost doubled our international revenue versus the first half of '25, driven by our focused commercial approach in target geographies. In Germany specifically, as the largest HGNS market outside the US, we first entered this market back in 2023 as our commercial proof of concept, resulting today in a stable HGNS market share of up to 25% overall, with a market share in our top high-volume accounts of above 50%.

In the UK, we entered the market at the same time as competition in late 2024, and in our initial accounts, we are seeing market shares above 50% as well. In the Middle East, Nyxoah is the sole HGNS provider, and we continue to further expand, and we recently entered the market in the Netherlands.

Our strategy remains unchanged: exercise financial discipline in these markets with a goal of driving growth and breaking even in our international business, which we've been able to do already in Germany. With that, I will now turn the call over to John for a detailed overview of our financial results.

Thank you, Olivier. For the second quarter of 2026, worldwide net revenue was €7.7 million, which represents 21% sequential growth compared to the first quarter of 2026, and compares to €1.3 million in net revenue in the second quarter of 2025.

US net revenue was €5.2 million, representing 22% sequential growth over the first quarter of 2026. International net revenue was €2.5 million, representing 19% sequential growth over the first quarter of 2026.

For the six months ended June 30, 2026, worldwide net revenue was €14 million, compared to €2.4 million for the six months ended June 30th, 2025, and almost sixfold year-over-year increase primarily driven by our US commercial launch. Gross margin in the second quarter of 2026 was 60%, compared to 57% in the first quarter of 2026.

Research and development expenses were €9.5 million in the second quarter of 2026, compared to €10.1 million in the second quarter of 2025, due to a decrease in product development expenses. SG&A expenses were €15.6 million in the second quarter of 2026, compared to €10.7 million in the second quarter of 2025.

This increase was primarily driven by the continued buildout of our US commercial organization. Total operating loss for the second quarter of 2026 was €20.6 million, and remained relatively flat compared to €19.9 million in the second quarter of 2025.

Please note that our operating expenses in the second quarter of 2026 included a one-time non-cash share-based compensation charge of approximately €900,000 due to the repricing of employee equity incentive awards. Non-GAAP cash operating expenses were €21.8 million, or essentially flat compared to €21.7 million in the first quarter of 2026.

Non-GAAP cash operating expenses increased from €19.8 million in the second quarter of 2025, primarily due to the investments in our US commercial organization. During the second quarter of 2026, we secured $110 million in aggregate financing via a $95 million equity raise and the drawdown of the second tranche of our EIB loan in the amount of $15 million.

This additional cash removes the near-term financial overhang that had been a concern for investors, and gives us the capital to scale our US commercial business. As of June 30th, 2026, cash and cash equivalents plus financial assets totaled approximately €97.8 million.

Now I'll turn to guidance. For the full year 2026, our full year revenue guidance remains unchanged, and we continue to expect worldwide net revenue in the range of €36 million to €40 million.

We continue to expect gross margin in the range of 60% to 62%. We now expect total operating expenses in the range of €99 million to €102 million, an increase of €1 million due to the one-time share-based compensation charge recorded in the second quarter.

We continue to expect total non-GAAP cash operating expenses in the range of €88 million to €90 million. Non-GAAP cash operating expenses reflect expected total operating expenses less non-cash items such as depreciation, amortization, and share-based compensation expense.

We continue to target long-term gross margins above 80%, and believe our disciplined approach to operating expenses supports revenue breakeven below €150 million in revenue. With that, I'll now turn the call back over to Olivier.

Thank you, John. As we enter the second half of 2026, our priorities remain clear: first, accelerate investment in our US commercial organization in quarter three by further expanding from 40 to 55 territories, and implement growth initiatives focused on increasing the patient funnel; second, continue to execute on our focused US launch strategy targeting the top 400 high-volume HGNS accounts; and third, maintain a disciplined financial approach to OpEx and direct investments towards revenue growth drivers.

Before closing, I would like to thank all the Nyxoah employees for their contribution in making the second quarter once more a successful one. With that, I would now like to open the line for Q&A.

Hi. This is Kyle Winborne?]

on for Adam. Thanks for taking our questions and congrats on the progress.

I guess first I just wanted to ask about the quarterly cadence, if we could, with the revenue guidance. Is there any additional color you can give us on how you expect the remainder of the year to break out, kind of between Q3 and Q4, obviously understanding amidst the ramp for the launch that it should kind of continue to grow sequentially?

Just anything you can kind of help us with there, and maybe you could kind of just talk through your confidence level of achieving the guidance?

Sure. Absolutely.

I'll start with that part, first Kyle. I guess with regard to what we see in the funnel with regard to new surgeon trainings, VAC committee approvals, as well as the number of prior authorization patients that are in that position entering Q3, we're comfortable with the guidance for the full year of €36 million to €40 million, which reflects, based upon our first half revenue, a range of €22 to €26 million for the second half of 2026.

We would expect that revenue in the US to grow sequentially from Q2 to Q3, and then again from Q3 to Q4. Then from an international perspective, we expect it to be consistent in the back half of the year as compared to the first half of the year.

Great. That's helpful.

Then maybe just as my second question, on the ACCESS study, and we talked about this a bit on the Investor Day, just wanted to kind of check in to make sure everything kind of went well. I think you were planning to wrap patient follow-up shortly after the Investor Day, which would have been a couple weeks ago, and just to kind of confirm if you're still expecting initial data I think you were saying at or around the ISSS meeting, and if you're still on track for the PMA supplement for Q4, label expansion early next year?

Thanks.

Thank you for the question, and I'm happy to also share here some very positive news. We are finalizing the 12-month data as we speak, and we are preparing for the PMA supplement submission.

For ISSS, we just received the news that the podium presentation has been accepted for the CCC data. We will release all the CCC data during the ISSS congress on podium.

I invite everyone to attend and to be present. Then when it comes to the submission, also there we stay fully on plan.

We are finalizing our 12-month data, we are planning to get them submitted end of Q3, latest beginning Q4. Then there is the 180 days FDA review, and we expect, as we disclosed already previously, somewhere during the end of Q1, maybe beginning Q2 latest in 2027 a positive result, and also CCC added to our label.

Great. Thank you guys.

Hi, Suraj.

Hey, Olivier. Can you hear me all right?

Yes, now we can. Hello.

Good afternoon.

Good afternoon. Hey, Olivier, in terms of your prior authorization cadence, the numbers that you give exiting the quarter, how should we think about the cadence of these prior auths?

We can reverse engineer some of the US implants that are being done in the quarter. I'm more curious in terms of how much time are you all seeing for prior authorization from start to finish, and if there's specific cadence as a quarter progresses, just so that we can map it out for the next few quarters.

Yes, and this is a very interesting question. With 427 submitted prior authorizations entering quarter three, just to give some color, this is a significant increase of 77% compared to the number of prior authorizations we had entering Q2.

In absolute numbers, entering Q3, 427; if we go back in time, entering Q2, we had 241. Now that being said, the next question is how fast can a prior authorization result into an actual implant?

I'm sure if you do the math on sales, we end with approximately 240 devices that were sold, and if you then calculate Q1, we had roughly 240 prior authorizations that were transferred in Q2. Is this exact science?

No, it's not. Ballpark, we see that the majority, as we consistently communicated, that we transfer will also result in actual implants in the next quarter.

I hope this is answering the question, Suraj.

Got it. Olivier, our math is suggesting in Q2 you'll did roughly 240 implants.

I'm curious, out of the 180 active sites, what do you think this translates into your share? Are the 240 just in a certain subset of those active sites really?

The remaining really have to, even though they are active, have to really start contributing. Any additional color would be great.

Thank you.

Yes. Another very interesting question.

We were talking about having on average 15% market share in the sites where we are present when we exited, in fact, Q1. We can see that overall we are maintaining this 15%, but note that we have opened 89 new sites in Q2, which are getting their first experience.

We can also report that the longest standing accounts are showing market shares above 15%, and I'm even happy to share that our top account is passing already the 44% of market share. This is really promising if you see how fast we are opening new accounts, and then also if you see how the longest standing accounts, due to reordering and confidence in Genio, are showing stronger growth in market share than the 15%.

Got it. Hey, Olivier, one last question, forgive me.

Did I hear you correctly? You'll have not paired with Inspire for the C-code submission for the September editorial meeting?

Yes, this was correct. We are very transparent in this.

We participate as an industry partner. We are supporting also the discussion, the lead of the AAO-HNS, and they are talking about a comprehensive coding.

For September, we continue to support this approach, and we did not submit it for a dedicated code.

Got it. Thank you.

Oh great. Thanks for taking the questions.

I wanted to ask about the new center adds, the trained new physicians that you have. I think you pretty much doubled the account base in Q2.

That's a pretty significant step-up, of course, but trying to get a sense out of the line of sight accounts, high-volume accounts that you've laid out there, maybe how or why or what, I guess, we should be thinking about on a go-forward basis, at least in the back half of the year as it relates to the number of new centers you're expecting to bring on per quarter, maybe what that sets you up for into 20, '27, and then from a utilization perspective, where or, again, how would you expect utilization to kind of track in the near- to intermediate-term?

Yeah. No.

David, thank you for the question. We have a focused launch strategy focused on the top 400 high-volume HGNS accounts in the US.

To your point, we showed very strong results in Q2 by doubling the number of active accounts, bringing it to 180. To answer your question, we have to link this also with the number of territory managers or sales reps that we are having, and we had 40 entering Q2.

I communicated already a couple of times that on average our sales reps, they have five of those high-volume accounts. With 40 reps, it's easy mathematics, you can cover up to 200 high-volume sites.

Today, exiting Q2, we already have 180 who are active. Now in going forward, we did also our hiring again a new cohort of 15 sales reps, so that will bring our total to 55.

You do the same math, you see that we can go in quarter three, quarter four up to 225 to 230 implanting high-volume accounts with our current sales force. That's one thing that we are doing.

Now the next thing, also asking on productivity in our strategy, the strategy is going deep. Therefore, I'm extremely pleased also to see that we capture overall in all our accounts an average already of 15% market share, but I think more important is that we can see the accounts that were opened up already in Q4 or early Q1, that they're already going beyond this 15% market share and that we already have top accounts where we go above 40% market share.

All this is confirming that facilities, surgeons, and patients are embracing Genio, and I think that is the key takeaway message. We're growing extremely fast in the volume of accounts.

We also have more than 262 surgeons trained, again, showing the excitement of surgeons. What to expect in the second half?

The growth will be more or less reaching 225 to 230 accounts in the second half of '26, and then as we continue investing in hiring more sales people, this will also go hand in hand with having more accounts that we will open. It's not our strategy to open 1,000 accounts.

Our strategy stays to get as fast as we can to the 400 high-volume implanting accounts that we see across US.

That's helpful. Maybe just thinking about this, the other pieces of the guide for the year, to hit the gross margin line, it's a pretty significant step-up in the back half of the year.

Can you help us think through the moving pieces and your level of confidence behind hitting that? Then when you think about this, $88 to $90 million of non-GAAP OpEx expense in the back half of the year, where, I guess, should we be thinking about the bigger incremental dollar spend coming from in the second half of the year, meaning what, I guess, are you more so expecting to invest behind to drive this broader sales growth versus what's already kind of baked into the core of the business?

Thank you.

Yep, sure. Absolutely, David.

For the back half of the year, from a gross margin improvement perspective, we have ongoing projects that continue to drive gross margin up. These are smaller in nature.

For one example, the ES, which is a component of the device that's going to be removed in the second half of the year in the US, so that's going to help drive gross margin up to those levels. We continue to increase our yields over the course of the years we continue to produce products.

Those are the near-term drivers for 2026 in the back half of the year. In terms of OpEx spread, yeah, I would anticipate in the third quarter you'll see a bit of a sequential step-up from the second quarter, but more of the expenditures will be coming in the fourth quarter when we have a full quarter's worth of US sales rep expansion baked into that fourth quarter.

A bit of a step-up Q3 expense-wise, but more of it in Q4 to get to that full-year 88 to 90 number cash OpEx.

Okay. Thank you.

Welcome.

Hey, everyone. Joe [Federico?]

on for John. Thanks for taking the question.

Maybe just to circle back to reimbursement for a second, I know you mentioned that you have not submitted for a dedicated code and your competitor seemingly has submitted an application for review at the panel next month. Can you maybe just give us a sense of what your strategy would be, in the range of outcomes if their package is approved or denied, or just where are you thinking you go from there?

Definitely, Joe. I would like to start by pointing out that today the environment for hypoglossal nerve stimulation reimbursement is stable and supportive, and that with Genio we have a dedicated code, the C8011, that is in place.

Also for commercial payers, we see that there is clarity on the CPT code that they are using, and we're also seeing that we have 100% prior authorization. That is the starting base.

Next, I do think that the discussions that are ongoing in the Editorial Panel are extremely constructive. We see that the AAO-HNS is really taking the lead and is also trying to find and to discuss together with AMA finding the most optimal solution for HGNS in the future.

Coming to a comprehensive coding is part of this strategy. If that strategy is followed, the first comprehensive coding clarity would be effective in play January 1st, 2029.

Now going back to competition, yes, they went and they submitted in September for a dedicated code. They also did the same thing in April.

Just as a reminder, in April this was rejected, they have resubmitted. Our strategy with Genio stays and remains unchanged: we support the AAO-HNS, and we do want to follow and give our full support in also going to a comprehensive HGNS coding because there is a code in play, there is no risk at all, and moving forward we will see how the future will further evolve.

Okay. That's really helpful color.

Then maybe just a quick follow-up, just on mentioned the 40 trained sales reps entering the quarter and that the plan is to add the next tranche of 15. Maybe just as we sit in August, how is that hiring progressing?

Then, when do you think those additional reps will be trained and in the field being fully productive?

Yes, so as I mentioned also in earlier calls, we have a high demand of sales people who want to join Nyxoah, and this has continued. We are currently actively doing the interview process, we expect that we have all 15 onboarded definitely by the end of quarter three.

We will start doing their training beginning Q4 so that we can still get them active selling even during Q4, and definitely have a full selling and trained sales force of 55 people going in January 1st, 2027.

Great. Thank you.
