Sami Corwin has given his Buy rating due to a combination of factors that highlight PTC Therapeutics’ strong potential for growth.

Moreover, the successful launch of Sephience, particularly its broad acceptance across the PKU patient spectrum, is seen as a major positive.

This commercial success is anticipated to be a key growth driver for PTC Therapeutics, supporting the company’s path towards achieving positive cash flow in the future.
