Event Summary

Rosen Law Firm has reminded investors of Lantheus Holdings, Inc. about the November 10, 2025, lead plaintiff deadline for a securities class action lawsuit. The lawsuit alleges that Lantheus Holdings made materially false and misleading statements and concealed adverse facts regarding the competitive position of its product, Pylarify, between February 26, 2025, and August 5, 2025. Specifically, the lawsuit claims that Lantheus Holdings was not equipped to properly assess Pylarify's pricing and competitive dynamics and that an early 2025 price increase, despite prior price erosion, risked Pylarify's price point, revenue, and growth potential. Investors who suffered damages when the true details entered the market are encouraged to join the class action.
