Arista 10% Owner Andreas Bechtolsheim's Trust Sells $43.0 Million of Stock
A family trust tied to Arista Networks 10% owner Andreas Bechtolsheim sold $43.0 million of the company's stock last week, according to a Form 4 filed Monday.
The trust sold 260,000 shares on Nov. 5 in a series of trades at weighted average prices from $159.11 to $171.45 a share. Individual sales ranged from $158.35 to $171.5475, the filing said, putting the average price for the day at $165.45.
Bechtolsheim, who is a trustee of the family trust holding the shares, reports his Arista holdings as a 10% owner. After the sales, the trust held 180,015,156 Arista shares, according to the filing.
A prearranged plan
The sales were made under a Rule 10b5-1 trading plan that Bechtolsheim entered into on Feb. 20, 2026, the Form 4 said. Such plans let insiders set up trades in advance, on a schedule or price formula, which helps them sell without running afoul of insider-trading rules.
The 260,000 shares sold represent 0.14% of the trust's stake before the sales, meaning the trust kept 99.86% of its position.
The filing lists only open-market sales. It reports no purchases, option exercises or derivative transactions.
