Corporate Governance Analyst

Insider received dividend equivalent rights equal to common stock, increasing beneficial ownership to 110,390.1636 shares.

The transaction recorded on 09/30/2025 is an acquisition of dividend equivalent rights (DERs) tied to restricted stock units rather than an open-market purchase; the form lists the price as $0. DERs are described in the filing as the economic equivalent of one share and vest on the same schedule as the underlying RSUs, so they represent compensation-related equity accrual rather than a cash investment.

This action increases the reporting person’s beneficial ownership to 110,390.1636 shares according to the Form 4 and was reported by an attorney-in-fact on 10/02/2025. The filing contains no sale, option exercise, or cash purchase and discloses no additional terms beyond the vesting linkage.
