Investors of Lantheus Holdings Can Pursue Class Action Suit Against Securities Fraud

Investors of Lantheus Holdings: Your Opportunity Awaits

On October 20, 2025, the Rosen Law Firm, a renowned global advocate for investor rights, provided an important reminder for purchasers of securities in Lantheus Holdings, Inc. (NASDAQ: LNTH). Those who bought shares between February 26 and August 5, 2025, have until November 10, 2025, to take legal action concerning suspected securities fraud.

Important Information for Investors

If you acquired securities during this specified “Class Period,” you may be entitled to compensation through a contingency fee arrangement, meaning you won’t have to pay anything upfront. The process is straightforward—simply visit Rosen Legal or reach out to Phillip Kim, Esq., toll-free at 866-767-3653 for any clarifications regarding the class action.

Legal Background of the Case

The class action lawsuit claims that throughout the Class Period, defendants offered overly optimistic statements to investors while simultaneously delivering materially false and misleading information. Essentially, these deceptive practices obscured the true competitive standing surrounding Pylarify, a key product from Lantheus Holdings. It has been alleged that the company was unable to accurately gauge the pricing and competitive environment necessary to safeguard its market position.

Furthermore, Lantheus's decision to increase prices in early 2025 — despite experiencing price erosion the year prior — opened the floodgates for competitors. This failure to disclose critical information regarding pricing dynamics not only jeopardized Pylarify's revenue but also posed a risk to its overall growth potential.

Why Choose Rosen Law Firm

When considering your next steps, it’s crucial to retain experienced legal counsel. Rosen Law Firm is distinguished for its successful track record in leading securities class actions. Many firms promoting such notices lack the experience or resources compared to Rosen Law Firm, which has been recognized as a leader in the field. The firm has secured substantial settlements for investors, having achieved the largest ever securities class action settlement against a Chinese company to date. In 2019 alone, they secured over $438 million for their clients.

Next Steps for Interested Investors

To partake in the Lantheus Holdings class action lawsuit, please visit Rosen Legal for immediate assistance. Alternatively, you can call Phillip Kim, Esq. toll-free at 866-767-3653 or email [email protected]. A class has yet to be certified; hence, potential participants are advised to act promptly to ensure they are included.

You may also choose to remain an absent class member with no immediate action—your eligibility to receive compensation in any future settlements does not rely on being a lead plaintiff. However, if you aspire to serve as lead plaintiff, your application must be filed before the November 10 deadline.
