NEW YORK and NEW ORLEANS, Feb. 13, 2026 /PRNewswire/ — Former Attorney General of Louisiana, Charles C. Foti, Jr., Esq., a partner at the law firm of Kahn Swick & Foti, LLC (“KSF”), announces that KSF has commenced an investigation into Lantheus Holdings, Inc. (NasdaqGM: LNTH).
In August of 2025, contrary to the Company’s prior optimistic outlook for the growth potential of its flagship product, Pylarify, the Company disclosed an 8% year-over-year decline in Pylarify revenue, as well as cuts to its full-year guidance, widespread contract renegotiations and account losses.
Thereafter, the Company and certain of its executives were sued in a securities class action lawsuit, charging them with failing to disclose material information in violation of federal securities laws, which remains ongoing. Specifically, the lawsuit alleges, among other things, that defendants knew that its forecasting processes were unreliable and that management had materially underestimated the pricing and reimbursement risks created by a Centers for Medicare & Medicaid Services rule shifting hospital reimbursement for Pylarify from Average Sales Price to Mean Unit Cost rates.
KSF’s investigation is focusing on whether Lantheus’ officers and/or directors breached their fiduciary duties to its shareholders or otherwise violated state or federal laws.
If you have information that would assist KSF in its investigation, or have been a long-term holder of Lantheus shares and would like to discuss your legal rights, you may, without obligation or cost to you, call toll-free at 1-833-938-0905 or email KSF Managing Partner Lewis Kahn (lewis.kahn@ksfcounsel.com), or visit https://www.ksfcounsel.com/cases/nasdaqgm-lnth/ to learn more.
