Rhea-AI Filing Summary

Arista Networks director and CEO Jayshree Ullal reported multiple equity transactions tied to vested performance-based restricted stock units and trusts. On 08/20/2025 she acquired 20,592 and 27,664 shares through vesting of restricted stock units, and an additional vesting-related disposition of 24,216 shares was reported at an effective price of $132.78 related to tax withholding. After these transactions her direct beneficially owned common shares total 33,957 and 165,980 in separate line items; she also holds substantial indirect holdings through family trusts.

The filing clarifies that certain shares are held in trusts for children, relatives, and a family trust for which she is co-trustee, and that some restricted awards vest on scheduled quarterly dates tied to prior performance awards.

Positive

Vesting of performance-based restricted stock units indicates achievement of prior performance conditions and alignment with shareholder interests
Significant indirect holdings held in family trusts demonstrate continued long-term exposure to company equity

Negative

24,216 shares disposed at $132.78 to satisfy tax withholding reduced direct share count
Some shares are disclaimed beneficially for trusts despite reporting voting and investment control, which may limit direct economic stake disclosure

Insights

TL;DR Insider recorded scheduled vesting of performance RSUs with partial withholding for taxes and material indirect family-trust holdings.

The filing documents routine equity compensation activity: two performance-based restricted stock unit grants vested on 08/20/2025 producing 20,592 and 27,664 shares, and 24,216 shares were recorded as disposed at $132.78 to satisfy tax withholding. These are standard compensation mechanics rather than open-market purchases or opportunistic sales. The reporting person retains meaningful indirect exposure through multiple trusts totaling multi-million-share positions, indicating continued alignment with shareholder outcomes.

TL;DR Transactions reflect compensation vesting and trustee roles; disclosures show voting/investment control but disclaimed beneficial ownership for some trust assets.

The Form 4 clearly discloses the reporting persons roles as trustee/co-trustee for family trusts and the nature of indirect ownership. The statement that voting and investment control is shared while beneficial ownership is disclaimed for specific trusts is consistent with governance disclosure norms. The document notes scheduled vesting cadence for performance awards and tax-withholding disposals, which are routine and properly reported under Section 16.
