A securities class action has been filed against Zoetis Inc. (ZTS) on behalf of a “Class” of all persons or entities that purchased or otherwise acquired Zoetis securities between January 14, 2025 through May 6, 2026. This case has been filed in the USDC – SDNY.

The complaint alleges Zoetis misled investors by portraying its Companion Animal segment and flagship products as a durable growth engine driven by expanding markets, rising market share, and strong veterinarian adoption, while concealing that serious safety concerns, intensifying competition, and declining veterinarian confidence were materially eroding the segment’s sales growth, competitive position, and financial outlook.
The truth behind Defendants’ misrepresentations was revealed over the course of four disclosures spanning from August 5, 2025 to May 7, 2026. In the final disclosure on May 7, 2026, the Company reported first quarter 2026 financial results that reflected significant deterioration across its core Companion Animal business and sharply reduced its full-year guidance. On this news, Zoetis’ stock price plummeted 21.5% from $111.22 to $87.31.
As a result of Defendants’ wrongful acts and omissions, and the resulting precipitous decline in the market value of Zoetis securities, Plaintiff and other Class members have suffered significant losses and damages.
