What Is This Lawsuit About? The lawsuit alleges that Perrigo made materially false and/or misleading statements and/or failed to disclose to investors: (1) that the infant formula business acquired from Nestle suffered from significant underinvestment in maintenance, operational improvements, and repairs; (2) that Perrigo needed to make substantial capital and operational expenditures above the Company’s outwardly stated cost estimates to remediate the infant formula business; (3) that there were significant manufacturing deficiencies in the facility for the Company’s infant formula business; and (4) that, as a result of the foregoing, the Company’s financial results, including earnings and cash flow, were overstated.

On November 5, 2025, Perrigo released its third quarter 2025 financial results and lowered its full year guidance “due to soft OTC consumption & infant formula dynamics.” The Company also disclosed it was “initiating a strategic review of its infant formula business” including “reassessing the Company's previously announced investment in this business of $240 million.” On this news, the price of Perrigo shares declined by $5.09 per share, or approximately 25.2%, from $20.19 per share on November 4, 2025 to close at $15.10 on November 5, 2025.

The Lead Plaintiff Appointment Process. The federal securities laws permit any investor who acquired eligible securities during the class period to seek appointment as lead plaintiff in a class action lawsuit. Courts typically appoint the investor(s) with the largest financial loss in the case and the ability to represent the class rather than investors with simply the largest investment portfolio. Courts regularly appoint individual investors, whether acting alone or as a group, as lead plaintiffs. The rights of any investor who bought shares during the class period are generally already protected. However, lead plaintiffs have the power to influence case strategy and have a say in settlement decisions, as well as decisions concerning allocation of settlement funds among class members.
