On 28 Jul 2025, Arista Networks (ANET) CEO & Chair Jayshree Ullal filed a Form 4 disclosing the sale of 527,302 common shares. The disposals were executed in six trades at weighted-average prices of $115.58 and $116.00, affecting three family-related trusts: each child’s trust sold 72,761 shares, while a family trust sold 381,780 shares.
The transactions were made under a pre-arranged Rule 10b5-1 plan adopted 13 Dec 2024, suggesting they were scheduled rather than opportunistic. Following the sales, Ullal still controls 23,463,724 shares via the family trust and about 6.19 million shares in each child trust, preserving a substantial equity stake.
