AI Infrastructure Leader 'Arista' CEO Sells Shares Through 100 Billion Won Family Trust

Arista Networks, Inc. (NYSE: ANET) disclosed that in April its CEO, Jayshree Ullal, and certain outside directors have been selling shares on the open market through family trusts.

According to the filing, on April 13 and 16 Ullal, under a pre-established Rule 10b5-1 trading plan, disposed of approximately 600,000 shares via trusts set up in the names of her children and other family members. The transactions generated roughly $105 million in proceeds (about ₩150 billion).

Earlier in the month, on April 1, outside director Charles Giancarlo sold 8,000 shares through a family trust, realizing about $1 million (approximately ₩1.5 billion). That same trust continues to hold roughly $27 million worth of Arista stock (around ₩400 billion).

Analysts have recently highlighted Arista’s expanding role in AI infrastructure, and in mid-April the company’s share price hit a new 52-week high following several brokerage upgrades.

In March, Arista announced a multilateral standards agreement for next-generation, high-bandwidth liquid-cooled optical modules. The company has also scheduled the release of its first-quarter 2026 earnings for May 5 (local time), underlining its ongoing business expansion and formal reporting calendar.

Headquartered in Silicon Valley, Arista supplies high-performance Ethernet switches and a network operating system for data-center and AI workloads to major cloud providers and big-tech customers.

Ullal, who has led the company since its founding, noted in the filing that although she still participates in voting and investment decisions for the substantial holdings held by those family and children’s trusts, she does not retain beneficial ownership of the shares themselves.
