Insights

Equity Compensation and Governance Analyst

CEO conducted a sizable open-market share sale, reducing direct holdings but retaining a substantial equity stake.

The filing reports that **Energy Fuels Inc.** CEO **Mark S. Chalmers** sold **150,000 common shares** on 11/19/2025 at an average price of $15.603 per share. The transaction code "S" indicates an open-market or private sale of non-derivative securities. After this sale, he directly holds **911,343 common shares**, which remains a large absolute position in the company.

This kind of Form 4 event matters because it changes the CEO’s direct economic exposure to the business. A reduction of 150,000 shares represents a meaningful trim in personal holdings, even though his remaining stake is still significant. The filing notes the reported price is an average of multiple same-day trades, which is common for larger dispositions executed in several lots.

The key item to watch going forward is whether this sale appears isolated or is followed by additional Form 4 transactions in subsequent weeks or months after 11/19/2025. Repeated sizable sales over a short period could indicate a sustained change in the executive’s exposure, while a one‑off transaction would simply update the ownership baseline at **911,343 shares**. Monitoring future Section 16 filings will provide a clearer picture of any trend.
