Kenneth Duda, CTO und SVP Software Engineering sowie Vorstand von Arista Networks (ANET), meldete routinem盲脽ige Aktiengesch盲fte im Formular 4. Am 20.08.2025 sind mehrere Restricted Stock Units f盲llig geworden, wodurch 5.712, 3.884, 4.148 und 1.832 Aktien erworben wurden (jeweils mit $0,0 pro Aktie ausgewiesen, da es sich um f盲llige RSUs handelt). Am selben Tag weist die Meldung aus, dass 7.818 Aktien zu $132,78 pro Aktie ver盲u脽ert wurden, um Steuerabzugsverpflichtungen im Zusammenhang mit der F盲lligkeit zu erf眉llen. Der Bericht listet au脽erdem verschiedene indirekte Beteiligungen 眉ber Trusts und eine Stiftung auf, bei denen Herr Duda als Mit-Trustee oder Trustee fungiert, darunter ein Trust f眉r ein Kind, eine 501(c)-Stiftung und zwei GRAT/Annuit盲t-Trusts. Das Formular wurde am 22.08.2025 von einem Bevollm盲chtigten im Namen von Herrn Duda unterzeichnet.

Positive
  • RSU vesting: Acquisition of 5,712, 3,884, 4,148 and 1,832 shares via vested restricted stock units demonstrates continued compensation alignment with equity
  • Transparent disclosure: Form 4 lists indirect holdings by trusts and foundation and explains tax-withholding treatment, providing clear reporting of beneficial ownership
Negative
  • Share disposition: 7,818 shares were sold at $132.78 (reported as withheld for taxes), which reduces Mr. Duda's direct share count
  • Concentration in related entities: Significant indirect holdings held in multiple trusts and a foundation could complicate exact beneficial ownership attribution (as disclosed)

Insights

TL;DR: Insider reported routine RSU vesting and a small disposition for tax withholding; not a material shift in ownership.

The filing documents scheduled vesting of multiple restricted stock unit awards and the related acquisition of common shares at $0.0 per share, which is standard for RSU vesting. A disposition of 7,818 shares at $132.78 is disclosed and is explicitly identified as withheld to satisfy tax obligations. The transactions appear administrative and consistent with compensation vesting schedules rather than open-market trading for strategic reallocation. Indirect holdings remain significant through family and charitable trusts, but the form does not show any large, discretionary sales or purchases beyond the withholding-related sale.

TL;DR: The filing records standard insider compensation settlements and trustee-managed holdings, with no governance red flags disclosed.

Reported activity includes vested RSUs converting to common stock and a simultaneous disposition to cover tax withholding鈥攃ommon practice for executive equity awards. The report clearly states Mr. Duda's roles and his trustee/co-trustee relationships for several entities that hold shares, with disclaimers of beneficial ownership where applicable. There are no indications of unusual related-party transactions, accelerated transfers, or other governance concerns in the disclosed items.

FAQ

What transactions did Kenneth Duda report on ANET Form 4?

The filing shows RSU vesting on 08/20/2025 that resulted in acquisitions of 5,712, 3,884, 4,148 and 1,832 shares, and a disposition of 7,818 shares sold at $132.78 to satisfy tax withholding.

Were the acquired shares purchased with cash on ANET Form 4?

No. The acquisitions were from vested restricted stock units recorded at $0.0 per share, reflecting conversion of RSUs to common stock rather than a cash purchase.

Why were shares sold according to the Form 4?

The filing states shares were withheld/sold to satisfy tax withholding obligations related to RSU vesting.

Does the Form 4 show Mr. Duda reducing his overall ownership significantly?

The report lists a sale of 7,818 shares, but also records multiple RSU vesting events and substantial indirect holdings via trusts and a foundation; the filing does not show a material strategic divestiture.

What indirect holdings are disclosed by Kenneth Duda on the Form 4?

The filing discloses shares held in a child鈥檚 trust (co-trustee), a 501(c) foundation (co-trustee), and two annuity/GRAT trusts (one where he is trustee and one where spouse is trustee) as indirect holdings.
