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

Each company listed discloses SLP 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 SLP 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.
