Background of the Allegations

The foundation of this class action lawsuit is built upon statements made by Lantheus during its quarterly earnings reports. On May 7, 2025, the company announced disappointing financial results for the first quarter, revealing that sales of its radiopharmaceutical oncology product, Pylarify, had declined year-over-year due to what was termed a “temporal competitive disruption.” This announcement triggered a significant stock price drop of $24.35, equating to approximately 23.23%, closing at $80.49 at the end of the trading day.

Subsequent announcements did not promise relief to investors. On August 6, 2025, Lantheus disclosed similarly disappointing earnings for the second quarter, again missing profit and revenue expectations. Notably, the sales of Pylarify saw a continued decrease of 8.3% compared to the previous year, further compelling the company to scale back its growth projections significantly. Following this round of disappointing news, Lantheus's stock again plummeted, this time by $20.76 or 28.58%, with shares priced at $51.87 upon market close.
