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.
