Key Details

  • Transaction date: 2026-05-12; reported on Form 4 filed 2026-05-14 (timely within filing window).
  • Transaction type/code: A (Award/Grant) — derivative securities covering 10,958 shares reported at $0.00.
  • Shares owned after transaction: not specified in the provided excerpt.
  • Footnotes of note:
    • F1: Underlying shares vest on the earlier of the one‑year anniversary of the grant or the Issuer’s next Annual Meeting, subject to continuous service.
    • F2: Award issued under the Non‑Employee Director Compensation Policy; the director did not pay any consideration for the award.
  • No indication the award was exercised or sold; this is a compensation grant rather than a purchase or disposition.

Context This is a director compensation grant, common for non‑employee directors and not an immediate market activity signaling a buy/sell. Because the award is subject to vesting, the director does not have immediate vested shares to sell. For retail investors, such awards are routine; they dilute shareholders when exercised/vested but do not necessarily indicate insider intent to trade.
