Insights

Equity Compensation Analyst

TL;DR: An insider sale after recent restricted stock vesting increases available shares but appears routine.

The transaction shows 9,724 shares vesting on 10/01/2025 and a planned sale on 10/06/2025 through Fidelity, with an aggregate market value of $312,986.38. That links compensation vesting directly to immediate disposition of shares rather than long-term holding.

The seller previously sold 3,201 shares for $86,859.32 between 08/04/2025 and 10/02/2025, indicating repeated monetization of equity. Monitor near-term volume on NASDAQ around 10/06/2025 and any disclosed trading-plan dates to assess whether sales follow a structured plan or ad-hoc decisions.
