2. PTC Therapeutics' Q3 2025 Earnings: A Strong Launch for Sephience

PTC Therapeutics reported a robust third-quarter 2025 with total revenue reaching $211 million, driven by a strong performance from Emflaza and the successful launch of Sephience, a newly approved treatment for phenylketonuria (PKU). The company's non-GAAP EPS came in at $0.2, significantly beating estimates of -$1.19. The revenue growth was largely attributed to the $19.6 million generated from Sephience, with 521 patient start forms received from US centers. Non-GAAP R&D expenses were $91 million, and non-GAAP SG&A expenses were $74 million, indicating a substantial investment in the launch of Sephience.

Publication Date: Nov -16

📋 Highlights
  • Strong Q3 Revenue: Total revenue reached $211 million, with Sephience contributing $19.6 million in its first quarter as a newly launched PKU treatment.
  • Full-Year Guidance Raised: 2025 revenue outlook narrowed to $750–800 million, driven by Emflaza’s performance and Sephience’s successful launch.
  • Sephience Launch Momentum: Generated $14.4 million in the U.S. and $5.2 million ex-U.S., with 521 patient start forms and 341 patients on therapy (avg. 2–4 weeks from enrollment to treatment).
  • Robust Cash Position: Ended Q3 with $1.68 billion in cash, supporting future growth and R&D, alongside $91 million in non-GAAP R&D expenses.
  • Global Expansion Plans: Anticipating Japanese approval by year-end, with Germany entering a 6-month benefit assessment and Brazil targeting authorization for ~6,000 PKU patients.

Sephience Launch Update

The launch of Sephience has been highly successful, with 341 patients on commercial therapy and a strong response from healthcare providers and patients. The company has seen a rapid and favorable response to Sephience, with over 250 million lives covered by payers and no significant restrictions on access. The safety profile has been excellent, and the once-daily oral administration has been well-received by physicians. Refill dynamics are showing positive momentum, with the vast majority of patients prescribed Sephience in August or early September receiving refills.

Financial Guidance and Outlook

The company has narrowed its full-year guidance to $750-800 million, driven by strong performance from Emflaza and the successful launch of Sephience. Management expects to generate leverage ahead of Street expectations and has a plan to manage OpEx, with a decline expected in 2026. Analysts estimate next year's revenue growth at -46.0%, indicating a potential slowdown in growth.

Valuation Metrics

PTC Therapeutics' current valuation metrics indicate a mixed picture. The P/E Ratio stands at 7.86, while the P/S Ratio is at 3.4. The EV/EBITDA ratio is 6.43, suggesting a relatively reasonable valuation. However, the ROE is significantly negative at -182.66%, and the P/B Ratio is -37.94, indicating potential concerns regarding the company's profitability and book value.

Future Prospects

The company is expecting approval in Japan by year-end and anticipates a premium price for Sephience. Additionally, PTC Therapeutics is working on early access and named patient programs in Europe and expects to receive authorization for Sephience in Brazil this quarter. The company's R&D Day on December 2nd will provide further insights into its research programs, including the registrational trial for Huntington's disease, which has shown proof of target engagement and mechanism of action.
