Arista (ANET) President Kenneth Duda Exercises Options, Sells 43,333 Shares
What Happened
Kenneth Duda, President, CTO and a director of Arista Networks, exercised 17,333 shares at $15.28 per share on June 22, 2026 (cost ~$264,795). On the same day he sold a total of 43,333 shares in multiple open-market transactions, generating aggregate proceeds of approximately $7,428,234. The reported sale prices ranged roughly from the high $160s to mid $170s per share (see footnotes for detailed ranges).
This combination was an option exercise (transaction code M) followed by multiple market sales (transaction code S). Sales of this kind are commonly executed under pre-established plans and are often routine; the exercise itself increases the insider’s shares acquired but the net effect here was a large sale of already-held and/or newly acquired shares.

- Notable footnotes:
- F1, F10, F12 — many transactions were effected pursuant to Rule 10b5-1 trading plans (personal plan, plans for the reporting person’s children, and a plan for the reporting person’s 501(c) foundation).
- F11, F13–F15 — several holdings are in trusts or a 501(c) foundation for which the reporting person (and spouse) serve as co-trustee; beneficial ownership of some trusts is disclaimed.

Context
- The filing shows an option exercise followed by substantial open-market sales. Because multiple sales were executed through pre-established Rule 10b5-1 plans (including plans for family members and a foundation), these transactions are documented as routine plan-based sales rather than ad-hoc trades. For derivative activity: “M” indicates exercise/conversion of a derivative (options) — Duda exercised options at $15.28 and shares were subsequently sold under the plans above.
