Dror Bashan, CEO

Thank you, Mike, and thank you, everyone, for joining our Q1 2026 financial results and business update course. I want to begin by highlighting two points that underscore the strengths of our business today. First, during the quarter, we received the $25 million milestone from Chiesi, following the European Commission approval of El Fabrio's every four weeks dosing regime. As a result, we ended the first quarter of BC with $51 million in cash, providing us with a stock balance sheet and substantial financial flexibility, and sufficient funds to support our ongoing operation, as well as our phase two release study with PRX-115. Second, we are reaffirming our 2026 guidance. We continue to expect total revenue for the year to range from approximately $78 to $83 million, inclusive of the $25 million milestones received from KIS. Within that outlook, we anticipated Fabio revenues excluding milestones of approximately $33 million to $35 million, and Eliezer, approximately $20 million to $23 million. Taken together, this guidance reflects the strengths of our commercial partnerships and our confidence in execution across our business for the year ahead. We entered 2026 with a good momentum, with the regulatory progress for El Fabrio in Europe, which triggered the $25 million milestone payment, the continued enrollment of our PRX 1-on-5 phase 2 release study and a growing focus on our pre-clinical pipeline. We remain confident in our strategy for the years ahead. Our partner, Chiesi, continues to execute it well with El Fabio across approved markets. Following the European Commission recent approval of every four weeks regimen, we believe El Fabio is well positioned to meaningfully reduce treatment burden for eligible patients in the European Union without compromising efficacy. This added dozing flexibility strengthens El Fabrio's competitive position and supports broader adoption over time. In the United States, unchanged. Looking longer term with the global Fabri market, $2 billion by 2031, we believe El Fabrio has a potency percent market share globally, supported by its differentiated profile, particularly the continued expansion of El Fabrio positions as well for substantial long-term value creation. On our clinical side, PRX-115 continues to move forward as planned. The Phase 2 release study is actively evolving, and we remain encouraged by the program profile based on the Phase 1 data. We believe it has the potential to improve. We continue to expect top-line results in the second half of 2027. Beyond 1.1.5, our strategy remains centered on rare renal diseases, where we believe our capabilities and platform offer a clear advantage. In our view, our business model limits downside risk while preserving meaningful upside as we advance our clinical programs and continue our commercial partnership. I will turn the call over to Gilad for a detailed review of our financial results and outlook. Thank you, Rolf.

Gilad Mamlok, CFO

For the first quarter of 2026, total revenue was $33.8 million, given mainly by a $25 million milestone payment received from Chiesi following approval of the every four weeks dodging regimen for El Fabio in Europe. This milestone underscores the value embedded in our commercial partnerships. Revenues from selling goods were $7.4 million compared to $10 million in the first quarter of 2025. This change reflected flow and analyzer purchases by Pfizer and Fiocruz, mainly due to timing and inventory dynamics, and was partially offset by sales to Chiesi. As we have noted previously quarterly product revenues can fluctuate based on party purchasing patterns and we encourage investors to focus on full year performance rather than quarter to quarter viability cost of revenues was 4.1 million compared to 8.2 million for the same period in 2025. The decrease was mainly attributable to lower sales volumes to Pfizer and Fuerkruz partially offset by increased sales to PSG. R&D expenses increased to $5.4 million, up from $2.5 million in the prior year period, driven mainly by preparations for and initiation of the PRS-115 Phase II release study. This increase reflects a deliberate allocation of capital towards advancing PRS-115, which remains our top clinical priority. SG&A expenses were $3.1 million, up $0.5 million, reflecting modest growth year-over-year, largely attributable to personnel-related costs. As a result of the milestone revenues and ongoing cost discipline, net income for the quarter was $18.2 million, or $0.23 per share, and $0.22 on a fully diluted basis, compared to a net loss of $3.6 million, or $0.05 per share, in the prior year period. Importantly, the company continues to operate a profitable commercial business and milestone to provide additional upside without changing our underlying expense base. Turning to the balance sheet, cash, cash equivalent, and short-term bank deposits totaled $51 million as of March 31, 2026. We have no standing debt or warrants providing us with substantial financial flexibility to support our continued pipeline and transfer. In summary, we remain in a strong financial position and well-capitalized to advance our key programs to the next set of clinical and commercial milestones. With that, I will turn the call back over to Bro.

Dror Bashan, CEO

Bro, triggered by the EC approval, we hold approximately $51 million in cash as of March 31st of this year, giving us the financial flexibility to continue investing in the programs and partnerships that will drive our next stage. Our 2026 guidance and our expectation that El Fabio can achieve 15% to 20% market share of the Fabri market by 2026.

Our first question is from Ram Servaju with H.C. Wainwright. Please proceed.

Speaker 3

Thank you so much for taking our questions, and congratulations on a good quarter. I wanted to ask if you could comment on the core determinants of the cadence with which you expect to receive revenue from Chiesi regarding El Fabrio sales, and what you think the likelihood is, if any, of increases to the full year 2026 guidance for El Fabrio-related royalty-based revenue.

Gilad Mamlok, CFO

Thank you. So I think as we mentioned last time, we just received the approval for one in four weeks on 5th of March, and Kieri is now in the process of going country by country and getting the local reimbursement approval. So I think we are going to see the effect mostly in the second half of the year, and we expect the second half of the year to be much stronger with regards to care resales. At that point of time, we still stick to the same guidelines we provide.

Speaker 3

And secondly, can you provide any commentary on how enrollment is going in the release trial, and if you can potentially provide us with timing for completion of enrollment?

Gilad Mamlok, CFO

As we said before, we are not updating regarding the continuing progress of the enrollment. It does progress, as we mentioned. We have many sites open. Our target is to finish enrollment by the end of 2026 and have the top-line results in the second half of 2027.

Speaker 3

And then lastly, with respect to the positioning of 115 in the overall GAUT market, Do you expect this to change meaningfully with the advent of next-generation URAT1 inhibitors, or do you anticipate that the refactory gout market segment is more or less likely to remain the same?

Dror Bashan, CEO

Ram, this is Golo. Thank you. We believe, I would say, this segment of uncontrolled gout patients will stay, and that there will be, I would say, enough room and growing even just qualified for your recourse.

Operator

Our next question is from John Vandermeisten with SACS. Please proceed.

John Vandermeisten, Analyst — SACS

Good morning, Dror Galan, or good afternoon. I know you mentioned that it's only the very first initial stages of the launch of El Fabrio for every four weeks, but do you have any initial data or initial insight into the uptake in the market on that approach.

Gilad Mamlok, CFO

It's too early for that, John. Good morning and thank you. But we do see, I mean, when we talk with Chiesi, I mean, they're optimistic about the progress and they expect to see the progress. But again, in terms of seeing the actual results, I don't think we're going to see them before the second half of the year.

John Vandermeisten, Analyst — SACS

Understood. And there was a mention in the press release about Chiesi continuing launches and regulatory efforts around the globe. And can you give us an update on how things are going in that respect, any new geographies and any geographies that we should expect in the next few months or next quarters in terms of expanding exposure of patients to El Fabio?

Gilad Mamlok, CFO

So there are a few targets from Chiesi in the next 12 months, I would say. Some are more significant, some are less, but we are going to report them immediately once there's approval. It's a continuous route of getting more approvals, and we see them what they have in the pipeline, and we will update as soon as they receive the approval.

John Vandermeisten, Analyst — SACS

And then there's also mention of PRX-119, and I was wondering what's the next milestone for PRX-119? And I'm thinking also in terms of getting into the clinic or IND submission or something like that. How does that look, that program?

Dror Bashan, CEO

You know, we are developing and, you know, putting together different activities, if I may say, to make sure that we have, you know, we are on the right path, if I may say. We will update soon. I mean, to which specific indication this mechanism of action works. And then we will, of course, do that when we expect to start phase one.

John Vandermeisten, Analyst — SACS

All right. Thank you for taking my questions. Thank you.

Operator
