Key Details
- Transaction dates and amounts:
- 2026-03-11: 1,685 shares withheld/disposed at $49.16 = $82,835 (tax withholding; code F).
- 2026-03-12: 18,372 RSUs granted (code A; reported $0.00).
- 2026-03-12: 131,382 derivative award (options) granted (code A; reported $0.00).
- Vesting: The RSUs vest in three equal annual installments on March 11, 2027, 2028 and 2029 (footnote F2). The options vest in three equal installments on the same dates (footnote F3).
- Shares owned after transaction: Not specified in the excerpt provided; see the full Form 4 for total beneficial ownership.
- Footnotes: F1 explains the 1,685 shares were withheld for tax withholding on vested RSUs. F2 describes the RSU terms; F3 describes the option vesting schedule.
- Filing timeliness: Form 4 was filed on 2026-03-13 reporting changes as of 2026-03-11 and 2026-03-12 — this appears to be timely (Form 4 is generally due within two business days of the transaction).
Context
- RSUs are a compensation award that convert to shares upon vesting; they are not open‑market purchases and typically reflect compensation rather than a direct bullish bet.
- The 131,382-share derivative award is reported as stock options that will vest over three years; options require exercise to convert into stock and may carry an exercise price (check the full filing for exercise price and other terms).
- The small disposal was a routine tax-withholding action and does not necessarily indicate a change in sentiment.
