Arista CEO Sells Shares Worth 100 Billion Won Through Family Trust

Jayashree Ullal, CEO and board chair of Arista Networks, Inc. (ANET), sold nearly 660,000 shares of the company’s stock on the open market through family and children’s trusts on April 13 and 16 under a pre-established Rule 10b5-1 trading plan, disposing of approximately KRW 10.4 billion worth of shares. Earlier, on April 1, independent director Charles Giancarlo sold about US$1 million (approximately KRW 1.3 billion) of shares on the open market through a family trust. Following these transactions, the trusts associated with CEO Ullal still hold tens of millions of shares indirectly.

Arista posted strong Q4 results and, driven by growing AI networking demand, recorded full-year 2025 revenues of US$9 billion (roughly KRW 12 trillion). The company has scheduled its Q1 2026 earnings release for May 5, and with analysts recently raising estimates, the stock has hit a 52-week high. (Source: investing.com)
