Second Quarter 2023 Financial Highlights:

• Total revenues were $213.8 million for the second quarter of 2023, compared to $165.5 million for the second quarter of 2022.
• Total revenues include net product revenue across the commercial portfolio of $174.6 million for the second quarter of 2023, compared to $143.7 million for the second quarter of 2022. Total revenues also include royalty and manufacturing revenue of $39.2 million for the second quarter of 2023, compared to $21.8 million for the second quarter of 2022.
• Translarna net product revenues were $96.5 million for the second quarter of 2023, compared to $77.0 million for the second quarter of 2022. These results were driven by treatment of new patients and continued geographic expansion.
• Emflaza net product revenues were $65.7 million for the second quarter of 2023, compared to $56.8 million for the second quarter of 2022. These results reflect new patients and high compliance.
• Roche reported Evrysdi 2023 year-to-date sales of approximately CHF 705 million, resulting in royalty revenue of $36.9 million to PTC for the second quarter of 2023, as compared to $21.8 million for the second quarter of 2022.
• Based on U.S. GAAP (Generally Accepted Accounting Principles), GAAP R&D expenses were $185.9 million for the second quarter of 2023, compared to $157.3 million for the second quarter of 2022. The increase primarily reflects additional investment in advancement of the clinical pipeline.
• Non-GAAP R&D expenses were $170.3 million for the second quarter of 2023, excluding $15.5 million in non-cash, stock-based compensation expense, compared to $143.5 million for the second quarter of 2022, excluding $13.8 million in non-cash, stock-based compensation expense.
• GAAP SG&A expenses were $88.4 million for the second quarter of 2023, compared to $79.9 million for the second quarter of 2022. The increase reflects our continued investment to support commercial activities, including expanding our commercial portfolio.
• Non-GAAP SG&A expenses were $74.6 million for the second quarter of 2023, excluding $13.8 million in non-cash, stock-based compensation expense, compared to $66.0 million for the second quarter of 2022, excluding $13.9 million in non-cash, stock-based compensation expense.
• During the second quarter of 2023, PTC announced the discontinuation of preclinical and early research programs in gene therapy and a reduction in workforce as part of a strategic portfolio prioritization, which resulted in a one-time charge of approximately $8.0 million recorded to R&D and SG&A expense.
• The change in the fair value of contingent consideration was a gain of $128.9 million for the second quarter of 2023, compared to a gain of $15.2 million for the second quarter of 2022. The change in fair value of contingent consideration is related to the fair valuation of potential future consideration to be paid to former equity holders of Agilis Biotherapeutics, Inc. (Agilis) in connection with PTC's acquisition of Agilis, which closed in August 2018. As a result of the discontinuation of the Friedreich ataxia and Angelman syndrome gene therapy programs, PTC determined that the fair value for all of the contingent consideration payable related to Friedreich ataxia and Angelman syndrome was $0 and recorded a gain of $129.8 million, which is the primary driver of the overall gain during the quarter. An intangible asset impairment of $217.8 million was recorded in the second quarter of 2023 which also related to the discontinuation of Friedreich ataxia and Angelman syndrome gene therapy programs. The net impact of these gene therapy program discontinuations was non-cash expense of $88 million recorded within total operating expenses.
• The net loss was $198.9 million for the second quarter of 2023, compared to a net loss of $152.1 million for the second quarter of 2022.
