How BioMarin Turned a Competitive Threat Into a Royalty-Bearing Asset
BioMarin (BMRN) settled patent disputes with Ascendis (ASND) over achondroplasia treatments, agreeing to receive royalties on Yuviwel sales. Under the deal, BMRN will get 20% of U.S. sales and 18% in other regions until 2030. While this reduces competitive risk, Voxzogo's market share could still be pressured. Yuviwel generated €8M in Q2 2026, with further expansion planned. BMRN shares are up 13% YTD, trading at a P/S ratio of 3.06.
