SEC Form 4 Analysis: Arista Networks, Inc. (ANET)

Insider: Charles H. Giancarlo, Director Filing Date: 2026-08-24 Transaction Date: 2026-08-20

Transaction Summary:

On August 20, 2026, Charles Giancarlo, a Director at Arista Networks, acquired 538 shares of Common Stock. This transaction was coded 'M', indicating the acquisition resulted from the vesting and conversion of derivative securities, specifically Restricted Stock Units (RSUs).

Key Details:

• Security: Common Stock
• Transaction Type: Acquisition (Code 'M')
• Shares: 538
• Price per Share: $0.00 (This is typical for RSU vesting, as it's a compensation event, not a market purchase.)
• Ownership Change: Following the transaction, Mr. Giancarlo's direct holdings increased to 1,509 shares. He also indirectly holds 184,333 shares through a family trust.

Context and Significance:

The filing indicates this transaction is part of a scheduled vesting from an RSU grant made on May 29, 2026. The vesting occurs quarterly. As a routine and pre-planned component of executive compensation, this acquisition does not represent a discretionary investment decision by the insider. The number of shares is also minor compared to the director's total holdings. Therefore, the trading significance is considered low.
