Equity Ownership

HolderCommon Stock (#)RSUs Vesting ≤60 Days (#)Total Beneficial (#)% of Outstanding
Jonathan Mariner5,741 2,297 8,038 <1% (based on 76,243,231 shares)

Additional outstanding director RSUs (unvested) for Mariner: 4,594 as of Dec 31, 2024.

Stock ownership and alignment controls:

  • Hedging and pledging are prohibited for directors and officers.
  • Clawback policy compliant with SEC/Nasdaq rules (recoup excess incentive comp post-restatement).

Governance Assessment

  • Strengths:
    • Independent director with deep audit and finance background; active Audit and Nominating & Governance committee service enhances risk and governance oversight.
    • Compliant with director stock ownership guidelines; hedging/pledging prohibited; robust clawback policy.
    • No related-party transactions disclosed involving Mariner; clean conflicts profile.
  • Watch items / signals:
    • Elevated “withhold” vote in 2025 election relative to peers (39.9M For vs 19.1M Withheld), indicating investor scrutiny—monitor for underlying concerns (e.g., board composition, classified board, or broader governance issues).
    • 2024 director equity grant gap (policy-driven ineligibility) reduces annual refresh alignment; however, initial 2023 grants and unvested RSUs provide some ongoing alignment.
    • Say-on-pay support improved from ~72% in 2024 to a stronger approval in 2025 (48,954,527 For vs 9,973,348 Against), suggesting progress in aligning pay design with investor expectations; continued oversight from audit and comp committees remains important.

Overall: Mariner’s audit chair experience and independent status support board effectiveness and investor confidence. The 2025 election withhold rate is a notable governance signal to track, but absence of conflicts, compliance with ownership guidelines, and active committee engagement are positives for alignment and oversight.
