Radovich Peter 4

What Happened
Peter Radovich, President and COO of Mirum Pharmaceuticals (MIRM), exercised stock options on June 5, 2026 to acquire 16,988 shares at $19.19 per share, for a total cash outlay of approximately $326,000. The filing also shows the corresponding derivative (the option) was converted/disposed (reported at $0), meaning the option award was cancelled upon exercise. Footnote indicates the option was fully vested.

Context
This was an option exercise (insider converting/options-to-stock), not an open-market purchase or sale of existing shares. Exercises are common when options vest or when executives want to convert equity compensation into shares; they do not necessarily signal a buy/sell opinion. Because the filing reports exercise (and no immediate sale), Radovich now holds the acquired shares unless he subsequently sells them (no sale reported here).
