Reminder for LNTH Investors about Class Action Lawsuit

On September 27, 2025, the law firm Kessler Topaz Meltzer & Check, LLP notified investors of a securities class action lawsuit against Lantheus Holdings, Inc. (LNTH). The lawsuit concerns individuals who bought or acquired Lantheus securities between February 26, 2025, and August 5, 2025. The deadline for lead plaintiff submissions is November 10, 2025.

The lawsuit alleges that Lantheus made false statements and failed to disclose crucial information during the Class Period. Specifically, Lantheus provided misleading statements about the competitive position of PYLARIFY, its failure to assess pricing dynamics accurately, and the risks associated with a price increase in early 2025. These actions potentially threatened PYLARIFY’s pricing, revenue, and overall growth prospects.

Investors who suffered losses as a result of Lantheus’ alleged misconduct have the opportunity to seek appointment as a lead plaintiff by November 10, 2025. The lead plaintiff serves as the representative for all class members in legal proceedings and selects counsel to act on their behalf. However, investors can also choose to remain as absent class members and may still be eligible for potential recovery.

Kessler Topaz Meltzer & Check, LLP encourages Lantheus investors who experienced significant losses to reach out to acquire more information about the case. The firm is well-known for prosecuting class actions globally and has a successful track record of recovering substantial sums for those affected by corporate misconduct. It is important to note that the complaint in this case was initiated by a different entity and not by Kessler Topaz Meltzer & Check, LLP.

Ultimately, investors impacted by Lantheus’ actions are urged to consider their options and reach out for more information if they wish to participate in the litigation process. It is crucial to act promptly and make an informed decision regarding potential recovery efforts. Investors should assess their losses carefully and make a decision that aligns with their best interests in seeking redress for any harm suffered.
