Nkarta, Inc. furnished a press release announcing its financial results for the second quarter ended June 30, 2025, and attached that press release as Exhibit 99.1 to this Current Report on Form 8-K. The Form 8-K also includes a Cover Page Interactive Data File as Exhibit 104. The filing states the Item 2.02 disclosure (including Exhibit 99.1) is being furnished and shall not be deemed "filed" under the Exchange Act nor incorporated by reference into filings under the Securities Act or the Exchange Act unless the company expressly states otherwise.
The filing identifies the registrant as a Delaware corporation (Commission File Number 001-39370; EIN 47-4515206), lists its principal executive office in South San Francisco, California, and shows the company’s common stock trades as NKTX on the Nasdaq Global Select Market.

Nkarta reported a significant insider transaction involving Chief Medical Officer and Head of R&D, Shawn Marshall Rose. On June 23, 2025, Rose was granted stock options to purchase 500,000 shares of common stock at an exercise price of $1.75 per share.
The stock options have a structured vesting schedule:
- 25% of the options vest on July 23, 2026
- Remaining 75% vest in 36 equal monthly installments following June 23, 2026
- Options expire on June 22, 2035
This grant suggests a long-term retention strategy for a key executive, with the low exercise price potentially indicating recent stock price challenges or an incentive-focused compensation structure. The substantial size of the grant (500,000 shares) reflects the senior leadership position and importance of the R&D function to the company.

Nkarta, Inc. (NKTX) � Form 4 Insider Transaction Overview
CEO and Director Paul J. Hastings disclosed the sale of 1,790 common shares on 06/18/2025 at a weighted-average price of $1.79. The transaction was automatically executed to satisfy tax-withholding obligations triggered by the vesting and settlement of Restricted Stock Units and therefore was not a discretionary sale. Following the sale, Hastings continues to beneficially own 320,069 shares, which includes 2,000 shares purchased under Nkarta’s 2020 Employee Stock Purchase Plan on 05/31/2025.
No derivative securities were acquired or disposed of, and no additional transactions were reported. Given the small size of the sale—roughly 0.56% of the executive’s total holdings—the filing appears routine and does not signal any change in corporate strategy, financial position, or insider sentiment.
