'Arista' CEO Cashes Out Shares Worth 140 Billion Won Through Family Trust

Arista Networks, Inc. (ANET) CEO Jayshree Ullal sold approximately 660,000 shares of company stock held in a family trust under a Rule 10b5-1 plan on April 13 and 16, generating roughly $104 million (about KRW 140 billion) in proceeds.

Earlier, on April 1, director Charles H. Giancarlo—acting as co-trustee of a family trust—sold about 8,000 shares for approximately $1 million (around KRW 1.4 billion). That trust still holds equity valued at about KRW 40 billion.

Despite these sales, CEO Ullal continues to own tens of millions of shares indirectly and directly through various family and related-party trusts and personal holdings. She has disclosed that, for certain trust-held shares, she participates jointly in voting and investment decisions but disclaims actual beneficial ownership.

Arista’s stock has recently hit new 52-week highs as demand for AI data-center networking accelerates, prompting some research firms to upgrade their ratings and reflect strong growth expectations.

In its fourth-quarter 2025 earnings release, the company reported robust profitability and issued strong growth guidance for 2026, reaffirming the expansion of its AI and cloud-networking revenue streams.

Founded in 2004, Arista Networks is a U.S. cloud-networking provider specializing in switches and software for large cloud operators, enterprise data centers, and AI workloads. CEO Ullal, a network-industry veteran from Cisco, has led the company since 2008, driving aggressive expansion in data-center and AI networking following its IPO.
