Nkarta (NKTX)

Fiscal year 2025 executive and director compensation, incentive-plan design, equity activity, and governance — every figure in this brief is traceable to its exact location in the company’s SEC filing — the document, the section, the page, and the table, linked directly.

Companies that benchmark against NKTX
4 companies name NKTX as a compensation peer

Each company listed discloses NKTX in its own benchmarking peer group, as disclosed in each company's most recent proxy statement within the last two proxy seasons. Two companies are therefore absent by design: one that named NKTX in an earlier year and no longer does, and one whose own most recent disclosure is older than the last two seasons.

Equity transactions since the proxy statement was filed

Every insider equity transaction reported on Form 4 after the 2025 proxy statement — acquisitions, dispositions, exercises, and withholdings — and therefore not reflected in any table in that document.

Incentive-plan design — the Compensation Discussion & Analysis

We provide our executives with an annual base salary as a fixed, stable form of compensation that reflects the scope of an executive's role, responsibilities, experience, and sustained individual performance. We provide cash short-term incentive opportunities to incentivize the achievement of annual performance goals. In addition, we grant our executives long-term incentive compensation in the form of restricted stock units ("RSUs") and stock options to provide an additional incentive to grow our business and further link the interests of our executives with those of our stockholders.
