Equity Ownership
| Holder | Shares Owned | Options Exercisable | Ownership % of Outstanding |
|---|---|---|---|

Ownership alignment:
- Stock ownership guideline for non-employee directors: five times annualized cash retainer ($600,000 as of 12/31/2024); as of 3/18/2025, all non-employee directors had met the guideline except two newest (Bené, Chinn), implying Plummer is compliant .
Governance Assessment
- Strengths: Independent director; Audit Chair since 2020 with “financial expert” designation enhances oversight of reporting, controls, auditor independence, and ERM; strong attendance culture (Board/committees active in 2024); director pay tilted to equity with required holding, plus no hedging, supporting long-term alignment .
- Compensation governance: MD&C uses independent consultant FW Cook; independence reviewed with no conflicts; MD&C composition includes Plummer; no interlocks disclosed, reducing conflict risk in pay decisions .
- Potential risks/RED FLAGS: Dual service as Audit Chair and MD&C member concentrates governance influence but is mitigated by full Board independence and robust committee charters; no related-party transactions or pledging disclosed; continued monitoring of time commitments across external boards is governed by Nominating & Governance guidelines .
- Shareholder signals: 2023 say-on-pay support ~94% indicates broad investor alignment on compensation practices WM-wide, which Plummer helps oversee via MD&C .
