ZTS is trading at $122.70 (+57.65%) after hours on June 25, 2026, following a period of intense volatility and a sharp recent selloff.
- The stock had previously faced significant downward pressure due to a first-quarter 2026 earnings miss and a reduction in full-year guidance.
- Investors are monitoring ongoing securities class-action litigation involving allegations of fraud related to the company's May 7 earnings report, which has added a legal overhang to the stock.
- No fresh company-specific announcements were released to explain the magnitude of the after-hours surge, which follows a period of heavy selling and lawsuit-driven volatility.
