ZTS Zoetis Inc. Insider Trading

Board member Frank Damelio makes first open-market purchase at ZTS, buying substantial stake while stock trades well below 52-week high.

Frank Damelio, a Zoetis board director, has made his first open-market share purchase in at least three years, acquiring a meaningful stake equal to nearly half his existing holdings. This stands out because Damelio's prior Form 4 activity was entirely stock-based compensation (option exercises and grants); he's now using personal capital to buy shares, which is a distinct signal compared to passively receiving compensation. The purchase comes as the stock trades significantly below its 52-week high and has declined sharply over recent months, meaning Damelio is buying into weakness. Zoetis itself remains fundamentally sound—the company is profitable, generating growing revenue, and trades at a reasonable valuation multiple—so this buying into a pullback in an otherwise healthy business is what makes the trade noteworthy.

Director Bisaro Paul makes first open-market purchase of 2,000 shares as ZTS trades well below 52-week highs; part of 3-insider buying cluster in 14 days.

Director Bisaro Paul purchased 2,000 shares at the market, marking his first open-market purchase in the 36-month record — prior activity consisted entirely of stock-based compensation transactions. The purchase occurred as Zoetis trades substantially below its 52-week high and has declined significantly over the past quarter, but the company remains profitable with stable revenue growth and a reasonable valuation multiple. Notably, this purchase is part of a cluster of insider buying activity: three insiders acquired shares within a 14-day window, suggesting interest in the stock at current levels. Paul's decision to commit personal capital at a time when the stock faces headwinds distinguishes this from his typical compensation-driven filings.

Director Michael McCallister makes first open-market purchase of ZTS shares as stock trades well below 52-week highs.

Michael McCallister, a director at Zoetis, purchased shares on the open market for the first time, marking a notable shift from his prior Form 4 activity which consisted entirely of stock-based compensation exercises. The purchase occurs while ZTS trades substantially below its 52-week high, having declined significantly over recent months. The company remains profitable with steady fundamentals, suggesting McCallister is choosing to deploy personal capital into a company that still generates consistent earnings but has lost considerable value from its recent peaks. This is the type of entry point that typically attracts insider buying — weakness in a fundamentally sound business — and the fact that McCallister broke from his historical pattern of compensation-driven transactions to make a discretionary purchase underscores deliberate action on his part.
