("Lantheus" or "the Company") (NASDAQ: LNTH) and certain of its officers.

Class Definition

This lawsuit seeks to recover damages against Defendants for alleged violations of the federal securities laws on behalf of all persons and entities that purchased or otherwise acquired Lantheus securities between February 26, 2025 and August 5, 2025, both dates inclusive (the "Class Period").

Case Details

The Complaint alleges that, throughout the Class Period, Defendants made materially false and misleading statements and/or failed to disclose that: (1) Defendants provided overwhelmingly positive statements to investors while concealing material adverse facts concerning the true state of Pylarify's competitive position; (2) Lantheus was not equipped to properly assess the pricing and competitive dynamics for Pylarify; (3) the Company failed to disclose that its early 2025 price increase—issued despite prior price erosion—created an opportunity for competitive pricing to flourish, thereby jeopardizing Pylarify's price point, revenue, and overall growth potential; and (4) as a result, Defendants' statements about the Company's business, operations, and prospects were materially false and misleading at all relevant times.
