Perimeter Solutions (PRM) Director Sean Hennessy Receives Vested Options
What Happened Sean P. Hennessy, a director of Perimeter Solutions, reported acquiring 35,944 shares on February 26, 2026 through the vesting of previously granted option awards. The Form 4 shows six derivative acquisitions (code A) with an acquisition price recorded as $0 — these reflect vesting under earlier option grants rather than an open-market purchase or cash exercise. The vested amounts come from multiple option grants made between 2021 and 2025 and were triggered by the issuer meeting (or partially meeting) performance criteria for fiscal 2025.

Context These entries reflect option awards vesting based on performance conditions, which is common for executive and director compensation. The filing does not show any immediate sale of the vested shares or a cashless exercise; market value of the shares depends on PRM’s stock price at the time any sale might occur. Vesting events are informational about compensation and do not by themselves indicate buying or selling intent.
