Insights

Corporate Governance Analyst

Director reported a small, cost-free acquisition increasing stake to 2,064 shares.

The Form 4 shows a director-level acquisition of 341 shares on 09/30/2025 with a reported price of $0, which indicates a grant, award, or other non-cash transfer rather than an open-market purchase. For governance monitoring, this documents insider alignment with the company by increasing beneficial ownership, but the size is modest versus typical institutional holdings.
