I would now like to hand the conference over to your first speaker, Mr. Fabrice Chiraki, CEO. Please go ahead, Sal.

Thank you, operator. Good morning and good afternoon, everyone, and welcome to our Q4 and full year 2025 earning call. I'll be joined on this call today by Liven March, our new chief commercial officer, Anurag Rallon, our chief medical officer, and Kenneth Leonard, our Chief Financial Officer. On this call, we will be making forward-looking statements that are based upon our current insights and plans. As you know, these may differ from future results. As you saw in our press release, farming ended 2025 on a strong note, operationally and financially. Total revenues grew by 15% in the fourth quarter of 2025 and by 27% for the full year. Thanks to disciplined cost management, we delivered $26 million of operating profits in 2025 compared to a loss in 2024. We also significantly increased our cash position. Operating cash flow came in at $55 million in 2025, putting our cash position at year-end above that of the end of 2024 level, before the acquisition of Abreva. 2025 was marked by significant growth of our two commercial assets, Ruconest and Joenja. Ruconest grew 26% year-on-year and by 9% in the fourth quarter, with its efficacy with With its reliability and its rapid onset of action, Reconest is poised to remain an established on-demand treatment option for difficult-to-treat patients in an evolving HA treatment landscape. Liebern will talk more about Reconest's performance and its unique value proposition. Joinger grew 29% year-on-year and by 53% in the fourth quarter. fueled by the acceleration of new patients on drug in the U.S., but also increased demand in international markets, including in the U.K., where the drug was launched last spring, and in other countries through purchases under government-supported access programs. These results underscore farming's transformation from a single-asset company into a highly profitable high-growth diet tech with two commercial products and a late-stage pipeline with two programs offering billion-dollar self-potential. We highlighted these programs at our Invest Today last month, offering investors unique insights to our high-value pipeline. RecurNest is the foundation of our portfolio and a reliable cash engine for the future. even in a more crowded HAE on-demand market, given its efficacy profile on the difficult-to-treat patient subpopulation. Coenzyme is just at the beginning of its cycle, with multiple growth catalysts in APDS, international geographic extension, and potential expansion into much larger PIDs. Lefazimone, which we used to call KL1333, for primary mitochondrial disease is another billion-dollar-plus opportunity, with the registrational study now well underway. This combination of durable revenue, first in disease innovation, and an advancing late-stage pipeline positions farming well for substantial near-term and long-term value creation. Let me now turn to our outlook for the remainder of 2026. As announced at our investor day in February, we expect 2026 revenue between $405 and $425 million this year, representing an 8% to 13% growth with operating expenses increasing at a slower overall pace, even with substantially higher R&D investment in our pipeline fuel future growth. We expect continued recognized growth for the reason mentioned earlier and accelerating joint chart growth, fueled by the uptake in APDS patients above 12 years in the U.S. and potential future regulatory approval internationally. Regarding the U.S. pediatric label extension, we've been working to address the FDA request and we expect to have greater clarity on the resubmission requirements and timeline following the FDA Type A meeting, which is now scheduled at the end of March. 2026 is an important year for our pipeline, with the materialization of potential value inflection points. We have now completed the enrollment of two lanylizib Phase II trials for larger prevalence PIDs, and we expect a top-line data readout in the second half of this year. We also expect to complete enrollment in the Napa Zimone Pivotal Study this year, to be in a position for a data readout at the end of 2027. We are clearly determined to maintain strong financial discipline to optimize capital allocations on our growth drivers. This is critical as we strive to build an efficient and scalable organization and make farming a leading rare, ultra-rare disease company and deliver sustainable value for our shareholders. Let me now turn to Liv and March for deeper insight on the performance of our commercial portfolio.

Good day, everybody. Let me start with Rucanest, where the U.S. business delivered another year of strong and resilient performance. In 2025, despite the first new wave of treatment options in the HAE market in almost five years, Rucanest continued to grow as an essential therapy for patients living with severe high-frequency HAE attacks. Our strategy remains consistent. focus on high-attack patients who require fast, reliable, on-demand treatment, and ensure that we continue to execute against that differentiated value proposition even as new agents enter the market. For the full year, Rucanest delivered 26% global revenue growth and a volume growth in the U.S. of 20%, a clear indicator of the strong and durable demand for Rucanest in the acute segment. In quarter four, we delivered 9% global revenue growth versus the prior year quarter, and a 10% volume growth in the core U.S. market, continuing the upward trajectory of Rukinest. As expected, through Q4, we began to observe impact of newly launched therapies for HAE in the U.S. market, with some patients trialing and some already returning to Rukinest. Despite these competitive dynamics, we welcomed over 60 new enrollments in the U.S. in the fourth quarter, slightly above Q3. Rukinus added both new patients and new prescribers in the quarter, underscoring the resilience of our position in the difficult-to-treat patient segments and the clinical trust placed in Rukinus in real-world settings. That said... The high burden of HAE matters for patients who have high-frequency attacks. Attacks are often unpredictable and potentially life-threatening, and symptom severity often escalates within hours. Importantly for patients experiencing multiple attacks per month or patients who experience suboptimal responses to other options, dependable rapid relief is not optional. It is essential. And this high-frequency attack segment is precisely where we have seen consistent, durable use of Rukaness over time and where we expect Rukaness to remain highly relevant even as new treatments enter the market. To that end, a meaningful proportion of new patient enrollments in the U.S. are switches to Rukaness from other on-demand therapies, further emphasizing the continued need that high-attack patients have for an effective, reliable, one and done therapy like Ruchinest. And so when you put this together, the unpredictability of the disease, the high burden carried by certain patient segments, the limitations of some other acute therapies, and consistently strong clinical performance associated with Ruchinest, the unique value proposition for Ruchinest remains clear. Looking ahead, we foresee some pressure on our growth early in the year, but with no change in the need for an effective, rapid onset, reliable one-dose treatment like Ruchinest. With that in mind, let me turn to Joenja. For Joenja, we delivered a strong fourth quarter, building on the momentum we established throughout the year. Revenue grew 53% compared to the fourth quarter in 2024, reaching 19.8 million globally. for the full year to end regenerative $58 million, representing 29% growth year on year, and demonstrating both sustained utilization from patients and the expanding clinical recognition and treatment of APDS. In the United States, patient growth remained a central driver of performance. By the end of 2025, we had 120 patients on paid therapy representing a 25% increase over year-end 2024. This steady expansion of our treated population reflects strong physician confidence, consistent engagement with patient communities, and a team that executes with discipline and with urgency. Equally important, we made significant progress in broadening the pool of identified APDS patients, one of the most critical leading indicators in an ultra-rare disease. In 2025, the number of U.S. patients we identified diagnosed with APDS increased by 40, more than double the increase of 18 we saw in 2024. This growth in identified patients with APDS shows that our educational efforts, our diagnostic partnerships, and our medical engagement in the U.S. are working. Outside the U.S., We saw strengthening demand across international markets, including a solid first-year uptake in the United Kingdom, following the launch in April 2025. We also benefited from government-supported access programs, which allowed us to reach more patients who currently have limited therapeutic options. Taken together, these results give us a strong platform for Joenja in the years ahead. Finally, we expect geographic expansion and the anticipated four to 11-year approval in the United States to be meaningful contributors to growth. These two catalysts remain materially important to increase the number of patients who can benefit from Joendra and expand the global footprint of the APDS business. Internationally, we've already demonstrated our ability to execute. In the U.K., where Joanger launched in April 2025, we have seen solid early uptake and engagement of community. That success reinforces that our teams have the capability, the infrastructure, and the strategic focus needed to deliver in new markets. In the United States, our commercial teams are fully prepared to launch Joanger for children ages 4 to 11, pending FDA approval, And importantly, we already have 52 eligible patients identified, one-third of them currently on therapy through our Early Access Program, ready to transition at approval. This will give us a running start and positions us for early momentum once the label is approved. Beyond the U.S., our international organization is deeply engaged in progressing regulatory submissions and ensuring that reimbursement discussions can start when approvals are granted across Europe, Japan, and Canada. Across these three regions, we have over 80 patients already receiving Joenza through early access mechanisms, awaiting full regulatory approval and commercial availability. This represents a significant bulk in foundation for launch acceleration once those approvals are secured. And so as we're stepping into 2026, we do so with confidence. For Joenja, we have the right growth catalysts in front of us, and we have an organization that has demonstrated that it can execute launches with precision and continuity. This gives us confidence not just in the next quarter, but in the sustained global expansion of Joenja over the coming years. And with that, I'll now hand over to Dr. Anna Raverellen, our Chief Medical Officer, who will walk you through our progress across the pipeline and the upcoming development and regulatory milestones.

Thank you, Laverne. As we discussed at our investor day in February, PI3K Delta is a master regulator of the immune system, and imbalances here contribute to immune dysregulation in a number of primary immune deficiencies, or PIDs. This understanding serves as the foundation and rationale for our Joenja development efforts. APDS, where Joenja is currently approved, is a primary immune deficiency caused by a genetic defect that leads to PI3K delta hyperactivation. This results in the dysfunction of the immune system and is characterized by frequent and severe infections and a wide array of immune dysregulation consequences, as you see here. APDS is a progressive disease and leads to early mortality due to these complications, with unfortunately about 25% of patients dying by the age of 30. Based on this understanding of APDS, we have two ongoing phase two proof of concept clinical trials evaluating laniolisib in more prevalent PIDs, which share unmet medical needs, mechanisms, and disease pathology with APDS. These include the genetically identified primary immune deficiencies with immune dysregulation linked to altered PI3K delta signaling and common variable immune deficiency, or CVID, with immune dysregulation, which is identified independently of genetics. And as Fabrice mentioned, both of these studies have now completed enrollment. And as you see here, APDS falls under the broader CBID umbrella diagnosis, and Joenja, in fact, serves as a proof of concept for the work we are doing now in these much more prevalent PIDs. This slide highlights the opportunity now to broaden the use of Joenja. The prevalence figures here are for the U.S., but they illustrate the larger opportunity to serve patients and underpin peak sales potential above $1 billion. We're very excited about the work that I just discussed to study Joangia and these additional PIDs with immune dysregulation beyond APDS. These address significantly larger patient populations, which are five to 26 times the prevalence of APDS. In APDS, Laverne already discussed progress with patient identification and our commercial preparations for geographic and pediatric expansion. But let me update you now on the Variance of Uncertain Significance Project and the opportunity there. Following various discussions over many months involving Columbia and genetic testing labs, it became clear that the labs require additional evidence to reclassify VUSs. Understanding the consequences of VUSs remain a significant unmet need. and actually a public health problem for clinicians and patients. And as you see, the number of patients with VUS continues to grow. To complement the significant first batch of data, which were published in Cell, we are now planning new experiments to generate the data needed to allow genetic testing labs to evaluate VUSs. Following completion of these experiments, we plan to provide an estimate how many VUSs may be reclassified and how many patients may be ultimately diagnosed with APDS. In addition, the work published in Cell also suggested the prevalence of APDS could be significantly higher than we currently estimate. We convened a global advisory board and are now initiating work to explore and better understand the prevalence of APDS as well as the spectrum of disease. I'll now cover the progress we are making in APDS, including some of our near-term regulatory milestones. Overall, we made good progress in APDS during 2025 and early this year. While we are disappointed in the complete response letter we received from FDA in January regarding our regulatory submission for the pediatric label expansion for Joenja for the treatment of APDS in children ages 4 to 11, we believe we can address both the clinical pharmacology and analytical batch testing methodology issues outlined in the letter. A Type A meeting has now been scheduled with FDA for later this month, and we expect to discuss the agency's feedback and align on the path forward for resubmission. In Europe, we have filed a marketing authorization application for leniolus for patients 12 years and older, and now responded to CHMP's questions on manufacturing activities and quality controls, and believe we have addressed their concerns. We now expect a CHMP opinion on the MAA to take place at their meeting later this month, with potential EC approval in the first half of this year. Regarding the Japan NDA for Leniolusib for the treatment of APDS in patients four years of age and older, the Pharmaceutical Affairs Council meeting has recommended approval. This news was covered in the pink sheet, who importantly noted that this would represent the first approval for children with APDS ages four to 11. We now await the formal decision by the PMDA by the end of March. I'll now turn to our next pipeline asset, napasomone, or formerly known as KL1333. Napasomone has also progressed significantly in the past year. This is being developed for primary mitochondrial diseases, which is a group of rare disorders where mutations in mitochondrial DNA lead to significant fatigue and muscle weakness. Napasomone addresses this underlying disorder by normalizing the NAD plus to NADH ratio which is abnormally low in these patients. There are a large number of these patients already diagnosed across the U.S. and large European countries where they are treated at centers of excellence and part of strong advocacy groups. And here we have a registration-enabling study underway with endpoints agreed upon with FDA. And importantly, there was a blinded interim analysis in which both endpoints passed utilities. Since completing the acquisition of Obliva last year, we are making good progress in the second wave of the study and are on track to complete enrollment later this year with readout in 2027 and potential approval later in 2028. And with that, I'll turn it over to Kenneth now to discuss our financial results.

Thank you very much, Anurag. I'm pleased to now provide some color on our strong 2025 financial performance and our outlook for 2026. The fourth quarter was a strong finish with revenues of 106.5 million, being 15% growth versus Q4 of 2024. This was driven by continued momentum across our portfolio, including a 9% growth for Ruconest and a 53% growth for Joangia. Notably, Joangia annual revenues exceeded 50 million for the first time, triggering our first 5 million sales milestone payment in the quarter As a reminder, this milestone is recorded in cost of goods sold and therefore affected gross margin for the fourth quarter. Adjusted operating profit was broadly stable year over year after several offsetting one-off items. Fourth quarter 2025 expenses include $9.3 million in expenses related to Ableva and Apacimon following the completion of the Ableva acquisition this year. as well as the $5 million Juenja sales milestone payment just mentioned. Excluding these items to compare operating profit on a like-for-like basis to the fourth quarter of 2024, operating profit in the fourth quarter of 2025 would have been $14 million higher. Finally, cash and marketable securities increased by $12.2 million from $168.9 million at the end of Q3 to $181 million at the year-end, primarily driven by positive operating cash flow, reflecting the strength of our commercial performance. Turning to our full year 2025 results, our financials shows the continued strong execution of our strategy. Total revenues increased 27% to $376.1 million, driven by robust double-digit growth from both Rokenest and Joenja. Gross margin remained stable at approximately 88%, despite the $5 million Joangia sales milestone recorded in the fourth quarter. Operating expenses rose to $311.3 million, excluding $4.1 million of one-off restructuring costs related to our G&A reduction program announced in operating expenses were $307.2 million, and within our previously communicated guidance range of $304 to $308 million. Importantly, when also excluding the full $29.7 million of Ableva-related expenses, operating expenses increased only 2% on a like-for-like basis. This reflects disciplined cost management. In total, adjusted operating profit, which exclude non-recurring Ableva acquisition-related cost and other offsetting items, was $36.4 million, compared with a loss of $8.6 million in 2024. Excluding recurring Ableva expenses and the $5 million joint sales milestone, operating profit for 2025 would have been $24.4 million higher. Cash flow from operating activities totaled $54.7 million versus being slightly negative in 2024, showing the improved profitability and cash generation of the business. Cash and marketable securities increased $11.7 million to $181.1 million, despite $68 million used for the Aviva acquisition, again highlighting the strength of our underlying operational cash generation. Turning to our 2026 outlook, we reaffirm our expectation for total revenues of 405 to 425 million, representing full year growth of approximately 8 to 13% versus 2025. The growth is expected to be driven by continued growth for Ruconest in the U.S., partly offset by declining ex-U.S. revenue as we exit those markets, and accelerated growth for Joenja. For Rukernest, quarterly revenue typically fluctuates with patient ordering patterns and channel inventory movements, with the first quarter usually being the lowest. In Q1, 2026, inventory drawdowns are expected to impact U.S. Rukernest revenue growth by 7% to 9% year on year as market dynamics settle. This is factored into our full-year guidance, which assumes mid-single-digit lucanus growth at the midpoint of the range. For Juangia, we expect growth to accelerate with annual growth approximately 10 percentage points higher than in 2025. the pediatric APDS indication remains an important future growth driver, and we look forward to clarity on the U.S. approval timeline for patients age 4 to 11 following the upcoming FDA Type A meeting. In the meantime, U.S. pediatric revenues are excluded from our 2026 guidance. For operating expenses, we anticipate a range of $330 to $335 million, including more than $60 million of incremental R&D investments. This guidance also reflects the $9 million favorable impact from the 20% G&A headcount reduction program announced in October 2025, along with stable marketing and sales spending. Overall, we remain committed to financial discipline, prioritizing investment that drive near and long-term value creation for our shareholders. Because Juangia revenue is not expected to exceed $100 million in 2026, we do not assume the $10 million commercial milestone payments, which otherwise would be recorded in cost of goods sold. As communicated during our investor day in February and aligned With ex-U.S. rollout plans, no additional milestone payments are expected. We estimate cost of goods sold at 10% of revenues, corresponding to a gross margin of 90%. Finally, available cash and future operating cash flows are expected to fully support pipeline investments, including all pre-launch activities. With that, I will now hand over to Fabrice for his closing remarks.

Thank you, Kenneth. So in summary, we are pleased to report another strong quarter and a record year for farming in 2025 with $376 million of revenues and a shift to operating profitability and positive operating cash flow. Looking ahead, Ruconest is poised to remain a cornerstone treatment for severe HA patients, underpinning a strong revenue base. We see clear revenue catalysts ahead for JoinJar, with the product well-positioned to generate a significant proportion of our revenues in the future. Our upcoming clinical data readouts, including the two leniency phase two later this year and the Dapazimon pivotal study readout next year, each have the potential to unlock significant value and take the company to a whole new level. And finally, the decisive steps we have taken to improve financial discipline will support driving the positive bottom line. With strong commercial and development capabilities, a fit-for-purpose leadership team with strong new additions like Livern and Kenneth, and a scalable organization, we are committed to making 2026 another stepping stone in achieving our vision of becoming a leading global rare disease company. Let me now open the line for questions.

Thank you. As a reminder, to ask a question, please press star 11 on your telephone and wait for your name to be announced. To withdraw your question, please press star 11 again. Once again, please press star 11 to ask a question and wait for your name to be announced. To withdraw your question, please press star 11 again. Thank you. We are now going to proceed with our first question. And the questions come from the line of Lucy Codrington from Jefferies. Please ask your question.

Hi. Thank you for taking my questions. To begin with, Juvenger growth this year, how much of that are you expecting to come from the U.S. market versus international markets? And then secondly, looking at the U.S. market, of those 61 eligible patients that are not on treatment in the U.S., How many of these do you think could be converted to paid therapy versus how many have been considered and ruled out? And then finally, in terms of root and S dynamics, you mentioned that you have heard of patients coming back to treatment having tried the orals. Do you have any, I guess it would be anecdotal, commentary on how quickly the patients return having tried the orals? Thank you.

Very good. Thank you so much, Lucy, for those questions. I'll turn to Lieven in a minute, actually. Let me start with the last one on Reconest, and then we can take your two questions on Joe and Ja. It is true that we've seen some patients trying and coming back. As you know, and as Lieven reinforced, HA is a very significant severe disease, and patients got to be controlled, and especially patients who were used to highly reliable treatments. And so when those patients try another treatment and see that they're their crisis is not properly controlled, they tend to come back to their previous medication fairly quickly, because not controlling a crisis could be life-threatening. Now, when it comes to joint gas growth, as we said, we see the growth this year, in 2026, being fueled both by the continued growth in the U.S., as well as growth increasing in international markets. Obviously, the growth in international markets will come from the U.K., where the drug has been launched, new launch countries, and this will happen in a staged fashion, since once we receive marketing approval, will have to negotiate a price and reimbursement. So ultimately, a bigger portion of the growth will come from international markets, but that's going to be gradual. When it comes to more specificities on Joe and Jas' patient funnel, I'll ask Livan to comment.

Thank you. Thank you, Lucie, for your questions. how we would think about the patients considered for Joindra or eligible for Joindra in the U.S. and the pull-through to patients on therapy, that there would be a lag there as patients are going through the patient journey, a fairly complicated patient journey, seeing multiple physicians, the enrollment and then the reimbursement process before we get to patients on paid therapy. And so how I would think about the delta there and the opportunity, there's still a substantial proportion of patients both eligible and potentially reimbursable that would drive growth for us in the U.S. in 2026.

Maybe Lucy, this is Kenneth speaking. Maybe I can just add, out of the expected 200 growth in 2026, it will probably be around about 70%, 75% that will come from the U.S.

So 75% from the U.S.?

Of the growth in 2026 for Drenja, yes. Got it.

Thank you very much.

We are now going to proceed with our next question. And the questions come from the line of Joe Panjanit from HC Wayne Wright. Please ask your question.

Hey, everybody. Good morning. Thanks for taking the questions. I know might not be able to give color here ahead of the type A, but I'm going to ask anyway. Obviously, the reasons for your discussions, as Anurag said, were the clinical pharmacology and the analytical batches. Is there anything that you would consider sort of the lead rate-limiting step here? That's question number one. Question number two, regarding Rucanest, you touched upon this a little bit, but I guess You know, the Rukaness case can be split into two components, in my belief. So first, you have the medical component, which continues to make the case. And I'd like to touch upon the investor component and specifically your comments that, you know, patients are still seeing switches from the new therapies to Rukaness. So I was hoping you can provide some additional color as to why those switches are taking place. Thanks a lot.

Thank you, Joe, for these questions. So on the Taipei meeting, it's very difficult to speculate. I think Anurag has been clear on the question that were raised by FDA, and we are really looking forward to engage with the agency later this month to address their feedback and discuss a path forward. too soon to tell. Clearly, given what they've raised, we feel actually that these questions are addressable. And once again, we look forward to engaging with them. When it comes to RUCONEST, I'll let Leverne answer your question.

So thanks for your question, an important one. So as we've seen new agents entering the HAE market in the U.S. between June and August last year, as expected, we saw some trialing of both acute agents and new prophylactic agents in the U.S. market. What we're observing in our data currently, and it's still early, is within about three to six months, some of these patterns may start to shift. And we've seen some return of Rukines patients that have originally adopted or trialed a different product coming back to Rukines. But again, early days, and we're monitoring this closely and we continue to execute competitively based on Rukines' very different value proposition for patients specifically in the high attack segment where they are increasingly concerned with reliability and a fast on-demand treatment like Ruconest.

Appreciate the color. Thank you.

We are now going to proceed with our next question. And the questions come from the line of Jeff Jones from Oppenheimer. Please ask your question.

Good morning, guys, and congrats on the great year 2025. A couple of questions from us. You spoke a little bit to the cadence of moving patients from early access onto paid therapy. Any notable variations between Europe, Japan, Canada as you look to that? And then, as you look at the other primary immune deficiencies for Joengia and the Phase II readouts that you're anticipating, can you speak a little bit about next steps, what types of additional trials might be needed, and how to think about the path forward there? Thank you.

Thank you, Jeff, for these questions. access to to pet therapies for for for joan ja in international markets most of these markets are access centrally driven access so the dynamic is different compared to the u.s. where you send each patient you know needs to deal with different players so So in a centralized access system, things are slower at the beginning because you need to negotiate, obviously, with the authorities for reimbursement. When you get reimbursement, then afterwards the reimbursement process is extremely efficient. So we don't expect to see the same type of dynamic internationally. When it comes to higher prevalent PMDs, I'll ask Anne-Marie to elaborate.

Hi, Jeff. So on the question about what happens next, so as I mentioned, the studies have completed enrollment. We expect results later this year. The results that we're looking for, again, the endpoints that we're evaluating are clinically relevant endpoints similar to the ones that we looked at in APDS, as well as other clinically relevant endpoints. As we look at those endpoints, we'll plan to have a discussion with FDA and other regulators about the path forward. I think our base case here is that we would expect to do a phase three randomized type of study. However, I think you've also seen from FDA some openness and willingness to look at alternative mechanisms and pathways for patients with rare diseases, especially those where there's a plausible mechanism and there's a mechanism that's understood. So, those are the types of discussions that we would have with FDA, again, once we have the data to be able to plan the path forward.

Great. Appreciate the cover, guys. Thanks.

Thank you. We are now going to proceed with our next question. And the questions come from the line of Sushila Hernandez from VLK. Please ask your question.

Yes. Thank you for taking my questions. On Juvengia, you mentioned a different launch dynamic for international markets. So what kind of timelines are you working with for getting these patients in Japan and Canada on paid therapy? And in the UK, will you also start reporting the numbers of patients on paid therapy? So currently, how many patients in the UK are on paid therapy and how many have you identified? Thank you.

So when it comes to timelines, so we've elaborated a bit on our expectations when it comes to regulatory timelines in the very near future, when it comes to CHMP opinion from Europe and PMDA approval in Japan. In Japan, specifically, since you asked the questions, we would be submitting a price very shortly for reimbursement, and it takes about three months, actually, for the price to be granted. So today, we have launch timelines planned for the summer. We will be reporting more information on the international market on Joe and Ja in a pool fashion as soon as we have launches in more than one country. So this should happen very soon. It's absolutely essential, and you can count on transparency here. For the second part of your question, I'll let Lieveon elaborate.

Certainly. As Reese has said prior, as we look at different approvals coming online at different times in this year, every country fundamentally will be a country-by-country process as the approval and reimbursement processes are quite unique for the countries that we discussed. So how we think about conversion is conversion will depend on physician experience, diagnostic confirmation and testing, and access. And we are building those enablers systematically with the international teams to make sure that we are able to execute upon approval.

Okay, that's clear. Thank you.

We are now going to proceed with our next question. And the questions come from the line of Natalia Webster from RBC Capital Markets. Please ask your question.

Hi there, thanks for taking my questions. My first one is a follow-up on Treventa and the patients on paid therapy in the US. You added 18 in H1 2025 and 6 in H2. Appreciate that this takes time, but are you expecting for this rate to pick up into 2026? Then the second question is just on costs. You're guiding 6-8% growth in OPEX in 2026. And you mentioned some phasing considerations on the revenue side. Are there any particular phasing considerations for the cost through the year, particularly around the higher R&D costs and G&A cost savings? And then just finally on M&A, in the release, you mentioned continued focus on potential acquisitions and in licensing opportunities. So any additional colour on what your thoughts are there would be helpful. Thank you.

Very good. Thank you so much, Natalia, for your question. So I'll start with the last one when it comes to M&A. We have clearly a number of growth catalysts, both in our commercial portfolio and in our pipeline in the years to come. So obviously there is no urgency to do any transaction hastily. to compensate for any sort of weakness. Yet, we clearly aspire to leveraging proven capabilities and a great growth platform to take that to a whole new level and make farming a leading rare disease, ultra-rare disease player. And so we are constantly looking out for opportunities to expand our pipelines, Now it is absolutely essential that these opportunities, if they were to materialize, would be value-attractive. And that's really our commitment to our shareholders. So it's not about actually leveraging any external growth opportunities, but making sure that anything that we would consider would be complementary, would fulfill our mission, and will be quickly accretive from a value perspective. From a cost perspective, I'll let Kenneth elaborate.

Yeah, thanks for the question. I think, you know, the way to think about it is in the 2025 baseline, we obviously have also some one-off costs that were related to the transaction off-year pleader, so non-recurring transaction costs of about $10 million. And we also communicated earlier that we had about $4 million in costs related to the G&A reduction program. But then when you're looking into the more than $60 million incremental investments in 2026, we of course see the $9 million of savings in G&A come fully through, And, you know, then we have seen the impact in our planning of the strengthened capital allocation, which has allowed us to keep also marketing and sales costs flat. So there are different dynamics that are playing in, but I think, you know, the future speaks for itself that we're fueling where we're seeing the opportunities to advance, in this case, 2026, the pipeline. and are very diligent around spent discipline across all other areas.

And so lastly, coming to your question on joint jar, which is actually a very important question, because as I said, I really see joint jar taking a larger part of our revenues as the drug continues to grow significantly and realize its full potential. You heard that last year we really accelerated the uptake of the drug. We had more new patients on therapy in the U.S. that we had in 24. Also, we've identified more APDS patients in the U.S. in 25 than we did in 24. And so this is really fascinating. So, this year, we expect to continue to accelerate patient enrollment on joint jobs and, as a consequence, accelerate revenue growth.

Great. Thank you. We are now going to proceed with our next question. And the questions come from the line of Simon Scholes from First Berlin. Please ask your question.

Yes, hello. Thanks for taking my questions. I've just got two. So I was wondering if you could give us a timeline on the performance and collation of the results from these additional experiments you need to perform with regard to the variance of uncertain significance. And also, are you still confident that 20% of these VUSs will turn out to be APDs? And then just on Rukanest, you were talking about a possible infantry-related decline in or infantry-related effect on sales in Q1. Is this an unusually large infantry drawdown that you're expecting to see in Q1? I mean, that was my impression. And if so, why do you think you saw such a large infantry buildup towards the tail end of last year?

Thank you, Simon. So, let's start with VUS. Clearly, this is a sizable opportunity, and we are really committed to helping those patients accessing the right diagnostics. So, Anurag?

So, Simon, we are now planning these new experiments. These experiments, again, we're working with Columbia. They're actually going to be using new technology. new base editing technology to be able to generate different types of variants, generate more controls as they go through this process. It's too soon to tell in terms of the timelines as well as the actual number of patients that will actually be reclassified. But as this work gets underway over the coming months, we should be able to provide more details around it. Okay, thanks.

And, Simon, on the inventory part, the way we're thinking about it is that there's always this quarterly fluctuation of the business given the patient ordering patterns and the, you know, general movements. And we have also historically, if you go back in the previous years, seen that, you know, similar dynamics in the early part of the year. Now, it's a little bit, let's say, higher in terms of inventory drawdown and dynamics this year, and we kind of attribute that simply to some of those market dynamics are kind of settling now, and that inventory levels are just kind of returning to a little bit more of the normalized level. So impact-wise, it's a little bit higher, but the mechanics of how the quarters are fluctuating and the fact that their inventory impact in the first quarter are not new to us.

Okay, thanks very much.

Very good. So listen, I think with this, we are going to close our call. Thank you so much for these additional questions. And we look forward to keeping you closely informed on our plan. There are a number of important milestones coming up. And so we look forward to reconnecting with you very soon. Thank you so much. Thank you, Operator.

Thank you. This concludes today's conference call. Thank you all for participating. You may now disconnect your lines. Thank you.
