Insights

TL;DR: Director received and vested RSUs, aligning her compensation with shareholder value without any sale of shares.

The Form 4 documents a routine equity compensation event: an RSU grant made May 30, 2025, with one-quarter vesting Aug 20, 2025 and subsequent quarterly vesting. The director acquired 971 shares upon vesting and retains additional RSUs and stock, which supports alignment of interests between management and shareholders. There is no sale or disposition disclosed, and ownership remains concentrated in long-term equity rather than cashing out.

TL;DR: Transaction is standard compensation vesting; immaterial to Arista's capitalization but relevant for insider ownership tracking.

The reported issuance of 971 shares from vested RSUs is a non-cash, routine compensation event. Beneficial ownership after the transaction is 12,447 shares with 2,913 RSUs remaining. For investors monitoring insider activity, this is a standard grant/vest pattern rather than a signal of liquidity needs or disposition. The filing contains clear vesting schedule details for future monitoring.
