Financial Performance and ARIKAYCE Revenue Trajectory#
Insmed’s financial data reveals robust revenue growth but ongoing operational losses reflective of its R&D-intensive business model. For fiscal year 2024, revenue reached $363.71 million, up +19.17% year-over-year, driven predominantly by ARIKAYCE sales. Gross profit margin remained healthy at 76.43%, indicating efficient cost management in product delivery.

ARIKAYCE’s Q2 2025 revenue of $107.4 million (19% growth YoY) underscores its expanding market penetration, particularly in the U.S., Japan, and Europe, where growth rates reached approximately 45.3% and 48.3% respectively (source. The company’s reaffirmed 2025 revenue guidance of $405 million to $425 million aligns with this growth trajectory.
