4 terms

Rule 10b5-1 trading plan financial

"The exercise and/or sale of shares was effected pursuant to a Rule 10b5-1 trading plan entered into by the reporting person on February 20, 2026."

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.

family trust financial

"These shares are held by a family trust for which the reporting person is a trustee."

weighted average price financial

"The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $163.51 to $164.505, inclusive."

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.

ten percent owner financial

"The reporting person is identified as a ten percent owner of Arista Networks, Inc."
