Insights

Corporate Governance Expert

Sale executed under a pre-established 10b5-1 plan; beneficial ownership remains material.

The transaction is described as occurring under a 10b5-1 plan adopted on 03/05/2025, which indicates the sale was pre-authorized rather than a discretionary trade. That structure is a common governance practice to reduce timing concerns about insider knowledge.

Key dependencies include the plan's terms and whether further scheduled trades exist; monitor any subsequent Form 4 filings near-term for additional programmed sales.
