Insights

Insider vested 38,323 RSUs; ongoing multi-quarter vesting schedule disclosed.

The Form 4 shows an insider vesting event recorded under transaction code M on 10/01/2025, representing the conversion of 38,323 RSUs into common shares at a reported price of $0. The filing also reports remaining derivative holdings of 421,555 RSUs and direct ownership of 48,138 shares after the transaction.

This matters because the filing documents a scheduled compensation vesting rather than an open-market purchase or sale; the disclosed RSU tranche is part of a planned, time-based vesting that will occur in twelve substantially equal quarterly installments beginning 10/01/2025.
