'Arista' CEO Sells Shares Worth 140 Billion Won Through Family Trust

Jayshree Ullal, CEO and chairman of U.S. cloud-networking company Arista Networks, Inc. (ANET), sold nearly 600,000 shares on April 13 and 16 through a pre-arranged Rule 10b5-1 trading plan under a family trust, raising approximately $146 million (about ₩140 billion).

On April 1, director Charles Giancarlo sold 8,000 shares through a family trust, cashing out roughly $1 million (around ₩1 billion); the filing notes that the trust still holds Arista shares valued at several hundred billion won.

Even after these transactions, Ullal retains a substantial indirect stake—tens of millions of shares—via her children, relatives and family trusts, although the filing formally disclaims her beneficial ownership of the shares held by those trusts.

In its February 12 announcement of fiscal 2025 fourth-quarter and full-year results, Arista reported annual revenue exceeding $9 billion and quarterly net income over $1 billion, reaffirming its growth momentum driven by expanding demand for AI data centers and campus networks.

Following reports about integration with Google’s AI infrastructure network “Burgo,” Arista’s share price climbed to an all-time high of about $177 on April 22. The company is set to release its first-quarter 2026 results on May 5.

Headquartered in Santa Clara, California, Arista supplies data-center, cloud and AI network switches and the Linux-based EOS operating system, delivering software-defined networking (SDN) solutions to large cloud providers and enterprise customers.

Indian-born technology executive Ullal has led Arista since 2008, guiding it through its IPO and growing it into an S&P 500 company with a market capitalization of $100 billion. Board member Charles Giancarlo is likewise recognized as a veteran of global IT and telecommunications equipment firms, with extensive management and board experience.
