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.
Non-Qualified Stock Option financial
"security_title: Non-Qualified Stock Option (right to buy)"
A non-qualified stock option (NSO) is a contract that lets an employee or service provider buy company shares at a fixed price for a set period, like a voucher to purchase stock later at today’s price. It matters to investors because exercising NSOs creates ordinary income for the holder and can increase share count, affecting a company’s earnings and ownership mix; think of it as a future sale that can dilute existing shareholders and has immediate tax consequences for the recipient.
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.

Kenneth Duda reported exercising 17,333 non-qualified stock options at $15.2769 per share and, on the same date, Rule 10b5-1 plan transactions that sold 43,333 Arista Networks common shares across his direct account, a children’s trust and a 501(c) foundation.
Were Kenneth Duda’s Arista Networks (ANET) trades made under a Rule 10b5-1 plan?
Yes. Footnotes state the option exercise and share sales were effected under Rule 10b5-1 trading plans entered on March 11, 2026, including separate plans for his own holdings, for a children’s trust and for a 501(c) foundation where he is a co-trustee.
