Kahn Swick & Foti, LLC, a prominent securities litigation law firm, has launched an investigation into Lantheus Holdings, Inc. (NASDAQ: LNTH) and its officers and directors. The investigation follows a securities class action lawsuit filed against the company, alleging it failed to disclose material information about its flagship product Pylarify's pricing and reimbursement risks.

Why it matters

The investigation by Kahn Swick & Foti could lead to further legal action against Lantheus Holdings and its leadership, potentially impacting the company's financial standing and reputation. As a major player in the medical imaging industry, any findings of wrongdoing or breach of fiduciary duties could have broader implications for the sector.

The details

In August 2025, Lantheus Holdings disclosed an 8% year-over-year decline in Pylarify revenue and cuts to its full-year guidance, citing widespread contract renegotiations and account losses. This contradicted the company's prior optimistic outlook for Pylarify's growth potential. The subsequent securities class action lawsuit alleges that Lantheus and its executives failed to disclose material information about the pricing and reimbursement risks created by a Centers for Medicare & Medicaid Services rule shift.
