Nkarta Director Zachary Scheiner Receives 37,000-Share Option Award
What Happened
Zachary Scheiner, a director of Nkarta, Inc. (NKTX), was granted a derivative award on 2026-06-10: an option covering 37,000 shares with an acquisition price reported as $0 (no cash paid at grant). This is a grant/award (A) of a stock option rather than an open-market purchase or sale; no underlying shares were issued or sold in this filing.
Key Details
- Transaction date: 2026-06-10; Form 4 filed 2026-06-11 (filed promptly the next day).
- Award: option to acquire 37,000 shares; reported acquisition price $0 (derivative award).
- Vesting: 100% vests on the earlier of (i) June 10, 2027 or (ii) the day before the Issuer’s first annual meeting after the grant. Vesting also accelerates upon a qualifying change in control or the reporting person’s death/disability. (Footnote F1)
- Beneficial ownership: Scheiner holds the option for the benefit of RA Capital Healthcare Fund, L.P. and RA Capital Nexus Fund, L.P.; he is obligated to turn over any net cash/stock on exercise to the Adviser to offset advisory fees and disclaims beneficial ownership of the option and underlying stock. (Footnote F2)
- Shares owned after transaction: not specified in the provided summary; beneficial ownership is disclaimed per footnote.
Context
This was a grant of an option award (derivative) — not an exercise or sale — so no immediate proceeds or share transfers occurred. Because Scheiner holds the option on behalf of RA Capital funds and disclaims beneficial ownership, the filing reflects an institutional arrangement rather than a personal investment decision. Grants are common for board compensation and may vest over time or on corporate events; they do not, by themselves, indicate the insider is buying or selling stock in the open market.

Footnotes (2)
- [F1]All shares subject to the option vest 100% on the first to occur of (i) June 10, 2027 or (ii) the day immediately preceding the first annual meeting of the Issuer's stockholders to occur after the date of grant of the award. Each grant, to the extent outstanding and otherwise unvested, will become fully vested should a "change in control" of the Issuer occur (as described in the applicable award agreement) or upon the Reporting Person's separation from service with the Issuer due to the Reporting Person's death or "disability" (as described in the applicable award agreement).
- [F2]Under the Reporting Person's arrangement with RA Capital Management, L.P. (the "Adviser"), the Reporting Person holds the stock option for the benefit of the RA Capital Healthcare Fund, L.P. (the "Fund") and the RA Capital Nexus Fund, L.P. (the "Nexus Fund"). The Reporting Person is obligated to turn over to the Adviser any net cash or stock received upon exercise of the stock option, which will offset advisory fees owed by the Fund and the Nexus Fund to the Adviser. The Reporting Person therefore disclaims beneficial ownership of the stock option and underlying common stock.
