Companies that benchmark against AMTM
2 companies name AMTM as a compensation peer

Each company listed discloses AMTM 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 AMTM in an earlier year and no longer does, and one whose own most recent disclosure is older than the last two seasons.

Disclosed peer group — fiscal year 2024

The compensation peer group as the company disclosed it in its own proxy — the reference set behind the percentile above.

10a

Peer reciprocity

Of the companies Amentum Holdings 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 Amentum Holdings.

10b

Chief executive pay against the peer group

Most recent fiscal-year chief executive compensation at each disclosed peer, taken from that company's own proxy statement.

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.

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.
