Insights

Equity ownership and insider-transactions analyst

Form 144 details planned insider sales by Arista’s CEO and related trusts, but does not by itself change the company’s fundamentals.

Arista Networks CEO Jayshree Ullal has filed to sell 24,042 common shares, valued at $2,937,211, with execution expected around 11/25/2025 on the NYSE. These shares were recently acquired on 11/20/2025 via a PSU award from the issuer, indicating part of the sales relate to equity compensation rather than open‑market accumulation.

Over the prior three months, Ullal and related Ullal family trusts completed several sizeable sales, including 903,342 shares on 09/10/2025 for gross proceeds of $134,176,277.95. While these are large personal transactions, the company’s total shares outstanding were 1,259,285,070, which frames these sales against a substantial equity base. The filing includes the standard representation that the seller is not aware of undisclosed material adverse information, so the activity is positioned as a liquidity or diversification move rather than a response to new negative news.
