Form 4 filing overview: Puma Biotechnology (PBYI) Chief Financial Officer Maximo F. Nougues reported two open-market sales of company common stock executed on 07/08/2025 and 07/09/2025.
- Shares sold: 5,587 shares at $3.533 on 07/08/2025 and 3,935 shares at $3.535 on 07/09/2025, totalling 9,522 shares.
- Proceeds: Approximately $33,600 based on the disclosed sale prices.
- Post-sale ownership: 204,229 shares held directly after the second transaction, down from an estimated 213,751 shares before the first sale—an ownership reduction of roughly 4.5%.
- Rule 10b5-1 plan: The filing states the transactions were effected under a pre-established Rule 10b5-1(c) trading plan adopted on 12-14-2020.
The reported activity is routine insider selling rather than a grant or option exercise. Because the sales were pre-planned and represent a modest fraction of the CFO’s remaining stake, the market impact is typically viewed as neutral to slightly negative; insider sales can raise questions about confidence, but the use of a long-standing 10b5-1 plan mitigates concerns of opportunistic timing.
