Revenue
Ptc Therapeutics reported a 4.2% decline in total revenue, amounting to $178.88 million in Q2 2025 compared to $186.70 million in the same period the previous year. The drop was primarily driven by a reduction in net product revenue, which fell from $186.70 million to $118.33 million. However, the company’s royalty revenue contributed a robust $57.60 million, partially offsetting the decline in direct sales. Collaboration and license revenue added $2.94 million, further diversifying the company’s income streams.

Ptc Therapeutics significantly narrowed its net loss in Q2 2025, reducing it to $-64.85 million, a 34.6% improvement from $-99.18 million in Q2 2024. On a per-share basis, the company’s loss improved from $1.29 to $0.83, representing a 35.7% reduction. This marked a key milestone, as Ptc Therapeutics recorded the highest Q2 net income in its 16-year history, showcasing the company’s progress in achieving profitability.
