Governance Assessment

  • Board effectiveness: As C&HC Chair, Quirk led pay-for-performance oversight, including clear annual and long-term metrics and disciplined payouts, supporting alignment with shareholder value .
  • Independence/attendance: Independent, engaged committee cadence; Board attendance strong in 2024 (>95% overall) .
  • Ownership alignment: Equity retainer grants; robust stock ownership guidelines; no hedging/pledging allowed; directors in compliance as of YE 2024 .
  • Say-on-pay support: 95.14% approval in 2024 for 2023 executive compensation, signaling investor confidence in compensation oversight .
  • Potential conflicts: CLH disclosed related-party employment for founder’s family ($933k son; $136k son-in-law in 2024) under pre-approved policy; C&HC members (including Quirk) had no Item 404 relationships; monitor optics though immaterial to Quirk .
  • RED FLAGS: None identified specific to Quirk. Company-wide related-party employment of founder’s family merits ongoing oversight; staggered board persists (continuity vs entrenchment trade-off) .

Overall, Quirk’s HR/compensation expertise and independent leadership of the C&HC are positives for governance quality, with strong pay discipline, ownership alignment, and high say-on-pay support, and no direct conflicts or attendance concerns evidenced .
