• Shares sold: 3,104; 2,652; 2,002 (total 7,758). Reported aggregate proceeds ≈ $29,922.
• Post-transaction holdings: Not specified in the supplied summary.

Context
A sell-to-cover following RSU vesting is a routine tax-withholding action and does not necessarily signal a change in the insider’s view of the company. This was a sale to cover taxes on vested restricted stock units rather than an opportunistic open-market liquidation or a new investment.
