LNTH LAWSUIT: Lantheus Holdings Inc. Sued For Securities Fraud; Investors Should Contact Block & Leviton to Potentially Recover Losses

BOSTON, Sept. 10, 2025 (GLOBE NEWSWIRE) -- Block & Leviton announces that a securities fraud lawsuit has been filed against Lantheus Holdings Inc. (Nasdaq: LNTH) and certain of its executives. Investors who have lost money in their Lantheus Holdings Inc. investment should contact the firm to learn more about how they might recover those losses.

What is this all about?

The complaint alleges that Lantheus and its executives misled investors about the growth and pricing strength of Pylarify, its key prostate cancer imaging product, during the class period. The company repeatedly assured investors that Pylarify’s market leadership and premium pricing would support revenue growth, while concealing that price hikes and competitive pressures were eroding its market position. When quarterly results in May and August 2025 revealed sharp sales declines, reduced guidance, and intensifying competition, Lantheus’ stock dropped over 23% and 28% on those respective dates. The lawsuit claims that investors purchased shares at artificially inflated prices due to these misrepresentations.

Who is eligible?

Anyone who purchased Lantheus Holdings Inc. common stock between February 26, 2025, and August 5, 2025, and has seen their shares fall may be eligible, whether or not they have sold their investment. Investors should contact Block & Leviton to learn more.
