Arista (ANET) Director Lewis Chew Receives 538 Shares on RSU Vesting

What Happened

• Lewis Chew, a director of Arista Networks (ANET), had 538 restricted stock units convert/exercise into shares on August 20, 2026. The Form 4 shows an acquisition of 538 shares at $0.00 (conversion of a derivative) and a simultaneous derivative disposition of 538 shares at $0.00. This was a vesting/conversion event (not an open-market purchase or sale).

Key Details

• Transaction date: August 20, 2026; Form 4 filed August 24, 2026 (timely — within two business days).
• Reported transaction code: M (exercise or conversion of a derivative).
• Shares acquired: 538 at $0.00; shares disposed (derivative): 538 at $0.00.
• Shares owned following the transaction: not shown in the provided excerpt.
• Footnotes: F1 clarifies each RSU converts to one share upon vesting; F2 notes these RSUs were granted May 29, 2026, with 1/4 vesting on Aug 20, 2026 and continuing quarterly on or after Feb 20, May 20, Aug 20, Nov 20.
• No explicit tax-withholding or sale-for-cashless-exercise details were included in the provided filing excerpt.

Context

• This appears to be a routine RSU vesting/conversion for a director rather than a market buy or sale that would signal a change in sentiment. Derivative-code (M) entries often reflect conversion of RSUs/options into common shares; any share withholding for taxes or immediate sale to cover taxes would normally be separately reported (and is not shown here).
