The Allegations: Rosen Law Firm is Investigating the Allegations that Lantheus Holdings, Inc. (NASDAQ: LNTH) Misled Investors Regarding its Business Operations.

According to the lawsuit, defendants throughout the Class Period provided these overwhelmingly positive statements to investors while, at the same time, disseminating materially false and misleading statements and/or concealing material adverse facts concerning the true state of Pylarify’s competitive position; notably, that Lantheus was not equipped to properly assess the pricing and competitive dynamics for Pylarify; Lantheus failed to properly disclose that its early 2025 price increase, issued despite price erosion the year prior, created an opportunity for competitive pricing to flourish, risking Pylarify’s price point, revenue, and overall growth potential. When the true details entered the market, the lawsuit claims that investors suffered damages.
