Context

• This was a vesting of performance-based restricted shares, not a market purchase or discretionary sale. Withholding shares to pay taxes is a common, administrative step and does not necessarily indicate a change in sentiment by the insider.
• For retail investors, purchases or open-market buys tend to be stronger signals than routine awards or tax withholdings. This filing documents compensation-related vesting and tax settlement rather than a cash-in sale.
