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.
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.

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.

Each peer's compensation is from its most recently filed proxy; fiscal years differ by company. Each peer's figures come from its own filings; the subject company is highlighted. Peers whose chief executive compensation is outside our coverage universe are stated as such, never left blank.
Each figure's location is given both for the eye (section · page · table · row · column) and for a script (table/row/column index and exact character span in the filed document). Any figure can be independently confirmed against the source.
