THOMPSON JOHN WENDELL 4

What Happened
John W. Thompson, a director of Rubrik, sold a total of 13,500 shares in multiple open‑market transactions on June 1, 2026, generating roughly $1.14 million in proceeds. The filing also shows conversion/exercise entries for 11,000 derivative shares (no cash exercise price reported) and a grant of 3,709 restricted stock units (RSUs) on June 3, 2026 (see footnote F13 for vesting terms).

Key Details

• Primary sales: 13,500 shares sold on 2026-06-01 for aggregate proceeds ≈ $1,141,289. Per‑trade prices ranged roughly from $79.77 to $86.07. Several sales show weighted‑average prices with specific ranges noted in the filing (see F3–F12, F7–F9).
• Derivatives/Conversions: Filing includes entries for exercise/conversion of 11,000 derivative shares (codes M and C). These are reported with $0 or N/A exercise price in the Form 4 (see filing for exact mechanics).
• Grant: 3,709 RSUs were granted on 2026-06-03; they vest in four equal quarterly installments (Sept 15, 2026; Dec 15, 2026; Mar 15, 2027; Jun 15, 2027) per footnote F13.
• 10b5‑1 plan: At least some sales were made pursuant to a Rule 10b5‑1 trading plan adopted Oct 6, 2025 (footnote F1).
• Record ownership / Trust: Some shares are held of record by the John and Sandra Thompson Trust (footnote F2); Class B shares have conversion provisions (footnote F15).
• Filing timeliness: Form 4 was filed on 2026-06-03 for transactions dated 2026-06-01 — within the standard Form 4 reporting window (timely).

Context

• Sales executed under a 10b5‑1 plan are typically pre‑scheduled and are considered routine compliance trades rather than a direct, immediate signal of the insider’s view.
• The filing’s derivative entries (exercise/conversion) and zero/N/A prices suggest non‑cash conversions (e.g., vested awards or conversion of units) — consult the full Form 4 for legal/technical details.
• RSU grants vest over time and do not represent immediate cash value until vested and (if applicable) sold.
