Class Action Lawsuit Against Lantheus Holdings, Inc.

On October 10, 2025, Kessler Topaz Meltzer & Check, LLP, a prominent law firm, announced a class action lawsuit targeting Lantheus Holdings, Inc. (NASDAQ: LNTH). This legal action aims to represent investors who purchased Lantheus securities during the specified period between February 26, 2025, and August 5, 2025. The firm has set November 10, 2025, as the deadline for potential lead plaintiffs to come forward.

The Nature of the Allegations

The lawsuit alleges significant misconduct by Lantheus's management. The core of the complaint revolves around accusations that Lantheus made numerous misleading statements regarding its competitive product, PYLARIFY. More specifically, the defendants are charged with failing to disclose important information about their ability to assess pricing and competitive dynamics effectively. This lack of transparency reportedly misled investors about the company's performance and future prospects.

Particularly, the lawsuit highlights that Lantheus's price increase in early 2025 was enacted despite previous erosion in prices the year prior. This strategic decision allegedly opened the door for competitor products to gain market traction, thus endangering PYLARIFY's standing in the market, as well as the revenue and growth potential associated with it. The accusations suggest that investors were left unaware of these risks while deciding to invest in Lantheus.

Steps for Investors

For investors who have incurred significant losses as a result of Lantheus's alleged misconduct, the law firm urges them to take action. Kessler Topaz Meltzer & Check, LLP explains that eligible investors can seek to become lead plaintiff representatives by acting before the November 10 deadline. The lead plaintiff essentially serves as a representative for all individuals affected, helping to steer litigation efforts. The selection process typically favors those with the largest financial stake and who align with the interests of other class members.

Should an investor choose to remain passive, they can still be classified as an absent class member and may participate in any recovery should the lawsuit succeed. It is vital that affected investors keep track of their losses and consider their options in this ongoing legal battle against Lantheus Holdings.
