Corporate Insider Transactions Analyst

Officer received RSUs and sold a small block of shares at $34.75.

The filing shows 10,193 RSUs granted under the 2022 Omnibus Incentive Plan and treated as acquired/exercised on 10/02/2025, producing 10,193 shares of common stock recorded at $0 per share because RSUs convert to shares upon vesting rather than an open-market purchase.

Separately, 4,011 shares were sold on the same date at $34.75, reducing direct holdings to 6,247 shares with 281,530 shares reported indirectly via a CIS Trust. Watch near-term vesting dates over the next three years for incremental share deliveries that may affect share supply.
