Key Financial Performance
Fourth quarter net product and royalty revenue $263 million, a part of the full year total net product and royalty revenue of $831 million, which exceeded guidance of $750 million to $800 million. The increase was driven by strong contributions from mature products and the early launch of Sephience.
Full year 2025 total net product and royalty revenue $831 million, exceeding guidance of $750 million to $800 million. This includes $587 million of net product revenue, with $111 million from Sephience since its launch. The growth was attributed to solid contributions from mature products and the early Sephience launch.
Sephience revenue in the fourth quarter $92 million, contributing to a total of $111 million in revenue for 2025 since its launch. The strong start was due to broad uptake across all patient segments and age groups.
Non-GAAP R&D and SG&A OpEx for 2025 $728 million, below the guidance of $730 million to $760 million. This reflects disciplined operational expense management.
Cash, cash equivalents, and marketable securities as of December 31, 2025 $1.95 billion, compared to $1.14 billion as of December 31, 2024. The increase was supported by strong commercial execution, disciplined OpEx management, and the monetization of the Evrysdi royalty for $240 million in December 2025.
DMD franchise revenue for 2025 $382 million, including $66 million in the fourth quarter. This includes $39 million from Translarna and $27 million from Emflaza in the fourth quarter. The franchise revenue reflects the ability to defend these products despite headwinds.
Evrysdi royalty revenue for 2025 $244 million, with $79 million in the fourth quarter. The revenue was generated before the sale of the remaining Evrysdi royalty to Royalty Pharma in December 2025 for $240 million upfront.

Risk or Challenges
Regulatory Challenges: FDA has indicated that an additional study will be necessary to support NDA resubmission for vatiquinone, which could delay its approval and commercialization.
Revenue Dependency: The majority of 2026 revenue guidance is dependent on Sephience, creating a risk if the product underperforms or faces unforeseen challenges.
Geographic Expansion Risks: Expansion into additional geographies for Sephience involves regulatory approvals, pricing negotiations, and reimbursement challenges, which could impact timelines and revenue.
R&D Investment Risks: Significant investment in R&D programs, including RNA splicing and ferroptosis platforms, may not yield successful outcomes, impacting financial performance.
Competitive Pressures: The company faces competitive pressures in the PKU treatment market, which could affect Sephience's market share and revenue growth.
Economic Uncertainties: Economic conditions and payer dynamics could impact patient access and affordability for Sephience, affecting its adoption and revenue.
Operational Risks: The company’s ability to maintain high refill rates and low discontinuation rates for Sephience is critical to sustaining its growth momentum.

Key Q&A
Q:What is baked into the internal and external guidance for Sephience sales this year?
A:The revenue guidance for this year is $700 million to $800 million, representing 19% to 36% growth over last year. Most of the revenue is expected to come from Sephience, with the majority from the U.S. Contributions from other countries are expected later in the year. The guidance is considered conservative, and adjustments may be made as visibility improves.
Q:How are 'lost to follow-up' patients becoming aware of Sephience, and what trends are being observed in specialty centers?
A:'Lost to follow-up' patients are becoming aware of Sephience through social media and community networks. Many of these patients are now seeking therapy despite not visiting doctors previously. Specialty centers are initially trying Sephience on more difficult patients, and positive responses are encouraging broader adoption.
Q:What is the status of the additional study required by the FDA for vatiquinone?
A:The FDA has suggested an open-label or single-arm study with natural history control to provide additional evidence for approval. The company plans to meet with the FDA in the second quarter to finalize the study protocol, including subject numbers and duration. The study is expected to be less costly than a placebo-controlled study.
Q:What are the expectations for Sephience's discontinuation rate and the cadence of new starts?
A:The discontinuation rate is very low, in single digits, and primarily due to patient decisions rather than clinical reasons. The company expects a steady cadence of new patient starts throughout the year, supported by medical education, awareness, and case management efforts.
Q:How should Sephience's growth in Europe be viewed after the 6-month free pricing period?
A:The company is optimistic about maintaining a high price with low rebates in Europe. Pricing and reimbursement discussions are ongoing, and the clinical data from APHENITY and AMPLIFY studies are expected to support strong pricing.
Q:What are the reimbursement dynamics for Sephience in the U.S.?
A:Reimbursement dynamics have been positive, with policies written by government and commercial payers being favorable to Sephience. These include prior authorization to label, limited or no step edits, and refills ranging from 6 to 12 months. Reauthorization processes are straightforward and align with clinical results.
Q:What are the Q1 dynamics expected for Sephience, and where is the majority of demand expected to come from?
A:Q1 dynamics include typical seasonal factors, but the company expects continued broad penetration across patient segments. The majority of demand is expected from patients who have tried and failed previous therapies, with switches from other therapies expected over time.
Q:How are Japan and Brazil ranked in terms of revenue contribution potential for Sephience?
A:Japan and Brazil are key markets with significant revenue potential. Japan has about 1,000 PKU patients and is a high-priced market with orphan drug exclusivity. Brazil has over 5,000 diagnosed patients, and the company is leveraging named patient programs to drive revenue, with meaningful contributions expected later in the year.
Q:What is the status of the Phase III study for votoplam, and what are the potential approval pathways?
A:The Phase III study, INVEST-HD, is a placebo-controlled study with an interim analysis planned for efficacy and futility. The study could serve as a confirmatory study for accelerated approval or as a registration study. The interim analysis could potentially enable earlier approval.
Q:What are the expectations for Sephience's net pricing?
A:The gross-to-net range is expected to be between 15% to 25%. Initially, it will be on the lower end and gradually increase over multiple quarters.
Q:What are the plans for the vatiquinone study's primary endpoint?
A:The primary endpoint will depend on the study's duration. If the study is longer than 18 months, mFARS may be used as the primary endpoint to demonstrate significant slowing of disease progression.
Q:What are the expectations for Sephience's adoption in Japan and Brazil?
A:Adoption in Japan and Brazil is expected to be influenced by social media and patient networks. Japan has a concentrated patient population in centers of excellence, while Brazil's dynamics involve named patient programs and advocacy groups. Both markets are expected to contribute meaningfully to revenue later in the year.
Q:What are the first clinical proof-of-concept milestones for the splicing and inflammation programs?
A:For the splicing program, the next milestone is achieving development candidate status for the MSH3 molecule. For the inflammation program, the NLRP3 inhibitor is expected to enter Phase I by mid-year, and the DHODH inhibitor may start a Phase II program this year.
Q:What is the company's view on Palynziq's potential label expansion to adolescents?
A:The company believes Sephience will remain the first-line treatment due to its oral administration, safety, tolerability, and efficacy. Palynziq's challenges with safety, tolerability, and administration are expected to keep it as a second-line option.
Q:Review of Unclear Management Responses
A:Management avoided providing specific details on the Sephience discontinuation rate over time, the exact matching strategy for the vatiquinone study, and the triggers for the interim analysis in the Phase III votoplam study. Additionally, they did not disclose the exact timeline for reaching the higher end of the gross-to-net range for Sephience.
