Insights

Corporate Insider Trading Specialist

Director executed a planned sale of 10,000 shares under a 10b5-1 plan.

The transaction shows a 10,000 share sale at $9.78 on 10/06/2025 and was executed under a written 10b5-1 trading arrangement dated 08/23/2024. That structure is commonly used to provide an affirmative defense against insider trading claims when trades follow preset instructions.

This is a routine disclosure by a director who continues to hold 82,501 shares directly. Investors monitoring insider activity may note timing and size, but the filing alone does not indicate changes in company operations or governance.
