Arista (ANET) Director Robert Lavender Exercises RSUs

What Happened
Robert G. Lavender, a director of Arista Networks, reported the conversion/vesting of 807 restricted stock units into 807 shares on May 20, 2026. The Form 4 shows an "exercise/conversion" (code M) acquiring 807 shares at $0.00 and a corresponding disposition of 807 shares at $0.00. No cash value is reported for these line items.

Key Details

  • Transaction date: 2026-05-20 (reported on Form 4 filed 2026-05-22).
  • Reported transactions: 807 shares acquired via conversion (M) at $0.00; 807 shares disposed (M) at $0.00.
  • Shares owned following the reported transactions: not specified in the filing (footnote notes rounding and a fractional share may be included).
  • Footnotes: F1 clarifies each restricted stock unit (RSU) is a contingent right to one share upon vesting; F3 notes these RSUs were granted 3/14/2025 and vest quarterly (Feb/May/Aug/Nov 20), explaining the May 20 conversion.
  • No late filing is indicated (transaction on May 20, Form 4 filed May 22).

Context
This transaction reflects RSU vesting/conversion rather than an open‑market buy or sale. Form 4s for RSU vesting often show both the conversion (acquisition of shares) and a corresponding disposition line when shares are withheld or settled; the filing here reports both steps at $0.00. Such vesting events are routine compensation-related transactions and do not by themselves signal a change in insider sentiment.
