Key Details
- Transaction date: 2026-03-20; Form 4 filed: 2026-04-08 (filed late relative to the typical 2-business-day Form 4 deadline).
- Transaction code: A (award/grant).
- Shares awarded: 272,107 RSUs + 612,240 derivative/option-style awards = 884,347 total award units.
- Price: $0.00 per share/unit (grant, not a purchase).
- Shares owned after transaction: Not specified in the provided filing excerpt.
- Footnotes/vesting: F1 — RSUs vest over four years: 1/16 vests on May 20, 2026, then equal quarterly installments thereafter; each RSU converts to one share at vesting. F2 — The derivative award (option) becomes exercisable as to 1/16 of the underlying shares on May 20, 2026, with the remainder vesting in equal quarterly installments, subject to continued service.
Context
- These are compensation/retention awards, not open-market purchases or sales; they do not represent an immediate cash investment or liquidation. The derivative award is a future exercisable right and does not indicate an immediate exercise or sale. The late filing is noted (may reflect administrative delay), but the grant itself is a routine executive compensation event rather than an immediate trading signal for retail investors.
