Event Summary

A securities fraud class action lawsuit has been filed against Zoetis Inc. (NYSE: ZTS) in the United States — United States District Court for the Southern District of New York, captioned City of Ann Arbor Retiree Health Care Benefit Plan & Trust v. Zoetis Inc., No. 26-cv-04401 (S.D.N.Y.). The lawsuit alleges that Zoetis made materially false and/or misleading statements and failed to disclose material facts about its business, operations, and prospects during the Class Period from January 14, 2025 to May 6, 2026. Specifically, the complaint alleges that prescription growth and use of Librela, a pain treatment for dogs, was weakening following FDA safety warnings of serious neurological complications; Simparica Trio was losing significant market share to a lower-priced competitor; and dermatological products Apoquel and Cytopoint were also losing market share to competition. On May 7, 2026, Zoetis reported its 2026 first quarter financial results showing significant decline across its Companion Animal business, causing its stock price to fall 21.5%. Investors have until July 27, 2026, to seek lead plaintiff status. The law firm Kessler Topaz Meltzer & Check, LLP is informing investors of their legal rights.
