On May 7, 2025, Lantheus reported first-quarter results below market expectations, with Pylarify’s performance particularly falling short.

Then, on August 6, 2025, Lantheus again announced disappointing results. The company significantly reduced growth expectations for Pylarify—which had fallen 8.3% year-over-year—and slashed its fiscal year 2025 growth projections. Defendants attributed the losses to ongoing competition impacting Pylarify’s pricing dynamics.

In response to the August 6^th news, the price of Lantheus’ common stock declined 28.8% in a single day. The stock fell from a closing market price of $72.83 per share on August 5, 2025, to close at $51.87 per share on August 6, 2025.
