Insights
Large holder sells 260,000 ANET shares under a pre-set 10b5-1 plan.
Andreas Bechtolsheim, a ten percent owner of Arista Networks, reported open-market sales totaling 260,000 common shares on July 1, 2026. Prices across the tranches ranged from roughly the high $150s to around $170 per share.
The filing notes the exercise and/or sales were made pursuant to a Rule 10b5-1 trading plan adopted on February 20, 2026. Such plans are set in advance and are typically used for systematic, pre-scheduled selling, which reduces the informational value of timing for outside investors.
After these transactions, Bechtolsheim still holds 182,542,958 shares indirectly via a family trust and 111,848 shares directly, indicating that the reported sales represent a small fraction of his disclosed holdings in Arista Networks. Overall, this looks like a routine liquidity event by a major shareholder rather than a fundamental change in position.

Rule 10b5-1 trading plan regulatory
"The exercise and/or sale of shares was effected pursuant to a Rule 10b5-1 trading plan"
A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.
weighted average price financial
"The price reported in Column 4 is a weighted average price."
Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.
family trust financial
"These shares are held by a family trust for which the reporting person is a trustee."
open-market sale financial
"transaction_action": "open-market sale""
An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.
