Rhea-AI Filing Summary

Arista Networks, Inc. (ANET) reports that President and CTO Kenneth Duda restructured indirect holdings of Common Stock on September 8, 2026. An aggregate of 200,000 shares was transferred from a family trust into two Grantor Retained Annuity Trusts (one for him and one for his spouse), and the family trust’s position was reduced by the same amount. These are non-market, no‑price transactions among related trusts, and no Rule 10b5‑1 trading plan is reported. Following these changes, Duda continues to hold shares directly and indirectly through multiple trusts and a charitable foundation, and he disclaims beneficial ownership of shares held in trusts for his children.

beneficial ownership financial
"The reporting person shares voting and investment control over the shares but disclaims beneficial ownership"
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
