What Happened?

On May 7, 2025, Lantheus released its first quarter 2025 financial results, missing consensus estimates, specifically with the Company’s key Radiopharmaceutical Oncology product, Pylarify. The Company disclosed that Pylarify sales had decreased year-over-year due to an alleged “temporal competitive disruption.” Additionally, the Company reduced its full-year guidance.

On this news, Lantheus’s stock price fell $24.35, or 23.2%, to close at $80.49 per share on May 7, 2025, thereby injuring investors.

Then, on August 6, 2025, Lantheus released its second quarter 2025 financial results, once again missing estimates and significantly reduced growth expectations for Pylarify, due to ongoing completion impacting pricing dynamics. The Company further slashed its full-year guidance.

On this news, Lantheus’s stock price fell $20.76, or 28.6%, to close at $51.87 per share on August 6, 2025, thereby injuring investors further.
