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.

What Is The Lawsuit About?

The complaint filed in this class action alleges that throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, and prospects. Specifically, Defendants failed to disclose to investors that: (1) Lantheus did not have an accurate understanding of the pricing and competitive dynamics of Pylarify’s market; and (2) as a result, Defendants’ positive statements about the Company’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis at all relevant times.

If you purchased or otherwise acquired Lantheus securities between February 26, 2025 and August 5, 2025, the deadline to seek appointment as the lead plaintiff in the securities fraud class action is November 10, 2025.
