PATTERSON LEONE D 4

What Happened
Leone D. Patterson, a director of Nkarta, Inc. (NKTX), was granted a derivative equity award covering 37,000 shares on June 10, 2026. The Form 4 reports an acquisition price of $0.00 (i.e., a grant rather than an open-market purchase); no immediate cash payment or sale of shares was reported. The filing lists the transaction on 2026-06-10 and was filed on 2026-06-11.

Key Details

• Transaction type: Grant / award (derivative) of 37,000 shares (code A on Form 4).
• Transaction date: 2026-06-10; Form 4 filed: 2026-06-11 (timely).
• Price reported: $0.00 (grant), so no dollar total is listed on the Form 4; intrinsic value depends on NKTX market price.
• Shares owned after transaction: Not specified in the provided filing excerpt.
• Footnote: Award vests 100% on the earlier of (i) June 10, 2027 or (ii) the day before the issuer’s first annual meeting after the grant. Outstanding, unvested awards will fully vest upon a qualifying change in control or upon the reporting person’s death or disability.

Context
This was a grant of derivative securities (an equity award with vesting conditions), not an open-market buy or sale. Such grants are common for directors as part of compensation and do not necessarily imply a near-term purchase or sale of company stock. The filing appears timely (filed the next day), and the vesting/acceleration terms are spelled out in the footnote.
