Investors Rally Against Lantheus Holdings Amid Class Action

Class Action Lawsuit Against Lantheus Holdings

Recently, Johnson Fistel, PLLP has taken significant steps by announcing a class action lawsuit targeting Lantheus Holdings, Inc. (NASDAQ: LNTH). This legal action aims to safeguard the rights of investors who have faced substantial losses due to alleged misleading statements made by the company. Investors who purchased shares of Lantheus between late February 2025 and early August 2025 are directly affected by this situation.

Who is Affected by the Lawsuit?

If you purchased Lantheus securities during the specified class period and experienced financial losses, you are encouraged to act promptly. The deadline for seeking appointment as lead plaintiff in this case is November 10, 2025. Individuals who believe they may qualify, particularly those who sustained considerable financial losses, should evaluate their eligibility for a potential recovery from this lawsuit.

Understanding the Case Against Lantheus Holdings

The crux of the class action revolves around claims that Lantheus Holdings grossly misrepresented key factors about its flagship product, Pylarify. This product serves as a PET imaging agent for prostate cancer and is central to the company’s business strategy. The allegations suggest that the company painted an overly optimistic picture regarding Pylarify’s competitive standing, pricing stability, and future growth prospects.

Impact on Investors Following Disclosure

On May 7, 2025, Lantheus revealed disappointing news regarding Pylarify's sales. The company reported a year-over-year decline, attributing this downturn to a “temporal competitive disruption.” In the wake of this announcement, Lantheus's stock faced a steep drop of over 23%. This was further compounded on August 6, 2025, when the company disclosed that Pylarify's second-quarter sales declined approximately 8.3% year-over-year, necessitating a further reduction in future earnings guidance, which led to an additional stock plunge of nearly 29%. These disclosures and their repercussions are at the heart of the lawsuit, as they significantly impacted the investments of numerous stakeholders.
