Event Summary

A class action lawsuit has been filed against Lantheus Holdings by Bragar Eagel & Squire in the United States — United States District Court for the Northern District of California. The lawsuit alleges that Lantheus Holdings made materially false and misleading statements to investors between February 26, 2025, and August 5, 2025. Specifically, the complaint claims that Lantheus Holdings concealed adverse facts about the competitive position of its product Pylarify, failed to properly assess its pricing dynamics, and that an early 2025 price increase jeopardized Pylarify's price point, revenue, and growth potential.
