Perrigo Securities Fight Intensifies as Law Firms Court Investors Over Infant-Formula Claims

Investors face a January 16 deadline to seek lead‑plaintiff status in a federal case alleging misstatements about the Nestlé‑acquired formula business.

Overview

Glancy Prongay, Rosen, and Portnoy issued new notices this week urging PRGO shareholders to join the case and consider seeking the lead‑plaintiff role by January 16, 2026.
The complaint alleges underinvestment in Perrigo’s infant‑formula unit, undisclosed remediation costs beyond prior estimates, manufacturing deficiencies, and overstated financial results.
DJS Law Group cites Exchange Act §§10(b) and 20(a) and SEC Rule 10b‑5 and lists a class period of February 27, 2025 to November 4, 2025, while other firms cite February 27, 2023 to November 4, 2025.
The suit follows Perrigo’s November 5, 2025 strategic‑review announcement and an outlook cut that coincided with an approximately 25% one‑day drop in the share price.
No class has been certified, motions for lead‑plaintiff appointment are due in the Southern District of New York, and investors remain unrepresented unless they retain counsel.
