Inhibrx (INBX) Director Kimberly Manhard Receives Option Award

What Happened Director Kimberly Manhard was granted 15,000 derivative securities (reported as a stock option award) on June 3, 2026. The Form 4 shows an acquisition of 15,000 shares at $0.00 (derivative), meaning no cash was exchanged by the insider at grant. This transaction is an award (code A), not an open-market purchase or sale.

Key Details

  • Transaction date: 2026-06-03; Form 4 filed: 2026-06-04 (appears timely).
  • Transaction type/code: Award/Grant (A) of derivative securities (stock options).
  • Amount: 15,000 options reported; Reported price: $0.00 (no cash paid at grant).
  • Vesting/exercise note: Footnote F1 — these options will be fully exercisable on June 3, 2027, subject to continued service through that date.
  • Shares owned after transaction: Not specified in the provided filing excerpt.

Context This was a compensation award of options, not an immediate purchase of ordinary shares. Options only become stockholders’ shares if and when exercised (and any vesting or service conditions are met). Such grants are common for directors and reflect compensation arrangements rather than direct market buying or selling; they do not by themselves indicate trading intent.
