Duda Kenneth 4

What Happened

• Kenneth Duda, President & CTO (and a director) of Arista Networks, reported on March 19, 2026 transactions that occurred on March 17, 2026. He exercised 32,000 option shares at $15.26 per share (cost: $488,400) and the filing records a separate conversion/derivative entry for 32,000 shares reported with $0.00 consideration. In addition, Duda sold a total of 58,000 shares in multiple open-market transactions that generated approximately $7,780,320 in proceeds (sales executed at prices roughly in the $132.47–$136.41 range across the reported lots).
• This activity is primarily sales (monetizing shares) combined with option exercise. Sales are often routine but are informative to investors as insider liquidity events.

• Transaction date: March 17, 2026; filing date: March 19, 2026 (appears timely).

• Notable footnotes: several transactions were effected pursuant to Rule 10b5-1 trading plans entered March 13, 2025 (filing notes plans for the reporting person, for the benefit of his children, and for a 501(c) foundation). Other footnotes note family trusts/annuity trusts and trustee roles; weighted-average pricing footnotes indicate multiple execution prices and offer to provide detailed breakdowns on request.

Context

• This filing shows an option exercise followed by same-day open-market sales of shares — a common pattern where insiders exercise options and sell some or all of the resulting shares (sometimes to cover exercise costs and taxes). The filing also includes a derivative conversion entry reported at $0.00; consult the full SEC filing or contact the company for precise mechanics if needed.
• The transactions were disclosed under standard insider rules and accompanied by 10b5-1 plan disclosures, which indicate pre-arranged trading instructions rather than ad-hoc market timing.
