Equity Ownership

HolderBeneficial SharesShares Outstanding (Record Date)Ownership %
R. Stewart Ewing, Jr.149,206 175,933,338 ≈0.085% (computed from cited figures)

Stock ownership policy compliance: As of last measurement date, all non-employee directors either satisfied or were on track to satisfy ownership guidelines; hedging and pledging are prohibited for directors under the Insider Trading Policy and Clawback Policy applies to incentive-based compensation .

Governance Assessment

  • Board effectiveness: Ewing chairs a fully independent Audit Committee and is designated as an Audit Committee Financial Expert, strengthening financial oversight and cybersecurity risk monitoring .
  • Independence vs. designation: While independent, his nomination by JPM Stockholders occurs within a framework where major holders have designation and voting commitments; this can create perceived influence/interlocks but is transparently disclosed and bounded by standstill/change-of-control restrictions .
  • Engagement: Attendance at or above the 75% threshold and expected participation in annual meetings; Board holds regular executive sessions to promote independent oversight .
  • Compensation alignment: Cash is modest, with a meaningful equity retainer in RSUs vesting over one year and director stock ownership guidelines set at 5x cash retainer, supporting alignment with shareholders .
  • Related-party exposure: Proxy lists related person transaction policies and describes stockholder agreements; no specific related-party transactions involving Ewing are disclosed beyond his designation status .
  • Shareholder signals: Say-on-pay approval was 98.7% in 2024, indicating broad support for compensation governance overseen by the Board and its committees .

RED FLAGS

  • Stockholder designation rights and coordinated voting by JPM Stockholders and Swarth could influence Board composition and committee leadership; monitor for potential entrenchment or conflicts in future nomination cycles .
  • Dilution capacity increased via proposed authorized share raise and new incentive plan; while intended for flexibility and talent retention, issuance could be used defensively—watch execution discipline and shareholder communications .
