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 IOSP 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 IOSP in an earlier year and no longer does, and one whose own most recent disclosure is older than the last two seasons.

Computed as the sum of the director compensation table rows above; inputs and formula shown in the register.
The compensation peer group as the company disclosed it in its own proxy — the reference set behind the percentile above.
Of the companies Innospec names as compensation peers, which name it back in their own disclosed peer groups. A peer set the market reciprocates reads differently from one selected in a single direction.
Reciprocity shown where the peer's own current proxy has been read — each mark is cited in the register to that peer's filing. A dash means the peer's current proxy was read and names no reciprocal group including Innospec.
Most recent fiscal-year chief executive compensation at each disclosed peer, taken from that company's own proxy statement.

Read from each company's Compensation Discussion and Analysis: annual incentive payout as a percentage of target, the disclosed long-term vehicle mix, whether performance-share measures include a total shareholder return component, and the retained compensation consultant. “Not disclosed” appears only where the company's filing does not state the item.
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.
