Context

• This was a standard vesting/conversion of RSUs rather than an open‑market purchase or sale. The $0.00 disposal typically reflects an internal transfer or delivery of shares (e.g., into a trust) rather than a sale for cash.
• Vesting of previously granted awards is common and does not by itself signal new insider sentiment about the company.
