What is this case about?
The Lantheus Holdings class action lawsuit alleges that the company misled investors by overstating the competitive position, pricing stability, and growth potential of its flagship product, Pylarify, a PET imaging agent for prostate cancer. According to the complaint, defendants made unduly optimistic statements about Pylarify’s revenue outlook while downplaying competitive and pricing pressures.
On May 7, 2025, Lantheus disclosed that Pylarify sales had declined year-over-year, citing a “temporal competitive disruption,” and cut its full-year 2025 guidance. Following this disclosure, Lantheus stock declined more than 23%. Then, on August 6, 2025, the company reported second quarter results showing Pylarify sales down approximately 8.3% year-over-year, and further reduced guidance, which allegedly caused the stock to fall nearly 29%. The lawsuit contends that investors suffered significant losses as a result of these revelations.
