(NASDAQ:LNTH) between February 26, 2025 and August 5, 2025, both dates inclusive (the "Class Period"). A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than November 10, 2025.

A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation.
Why Rosen Law: We encourage investors to select qualified counsel with a track record of success in leadership roles. Often, firms issuing notices do not have comparable experience, resources, or any meaningful peer recognition. Be wise in selecting counsel. The Rosen Law Firm represents investors throughout the globe, concentrating its practice in securities class actions and shareholder derivative litigation. Rosen Law Firm achieved the largest ever securities class action settlement against a Chinese Company at the time. Rosen Law Firm was Ranked No. 1 by ISS Securities Class Action Services for number of securities class action settlements in 2017. The firm has been ranked in the top 4 each year since 2013 and has recovered hundreds of millions of dollars for investors. In 2019 alone the firm secured over $438 million for investors. In 2020, founding partner Laurence Rosen was named by law360 as a Titan of Plaintiffs' Bar. Many of the firm's attorneys have been recognized by Lawdragon and Super Lawyers.
Details of the case: 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.

No Class Has Been Certified. Until a class is certified, you are not represented by counsel unless you retain one. You may select counsel of your choice. You may also remain an absent class member and do nothing at this point. An investor's ability to share in any potential future recovery is not dependent upon serving as lead plaintiff.
