Insights

Equity compensation analyst

Routine equity grant; compensation-related, not an open-market buy.

Lawrence D. Kingsley, a director of Mirion Technologies, received 1,104 Class A shares as his quarterly board retainer, electing vested stock instead of cash. The reference value used was $17.32 per share, indicating a modest-sized award.

The filing shows Kingsley now directly owns 64,047 shares and indirectly reports 3,509,075 shares via a revocable trust. This is standard director compensation, not a discretionary market purchase, so it carries limited signaling value about his view of the stock.

revocable trust financial

"By Lawrence D. Kingsley Revocable Trust"

A revocable trust is a legal arrangement where the person who creates it keeps control and can change or cancel the trust at any time, while naming who will manage and receive the assets later. Think of it like a flexible folder for your investments and property that can be relabeled or reworked as circumstances change; it matters to investors because it determines how ownership is recorded, how easily assets transfer on incapacity or death, and whether holdings bypass public probate proceedings.
