Corporate Governance Expert

Sales followed a pre-existing Rule 10b5-1 plan; large retained stake remains.

The sales totaling 5,000 shares were executed automatically under a Rule 10b5-1 plan adopted on 09/02/2024, which typically provides an affirmative defense against insider trading claims when properly documented. The filing discloses weighted average price ranges for the multiple transactions rather than single trade prices.
