Board Governance

  • Committee assignments: Member, Compensation Committee; Chair, Nominating and Corporate Governance Committee .
  • Independence: Board determined Seiffer is “independent” under NASDAQ rules; company currently complies with non‑controlled company standards though it qualifies as a “controlled company” due to LGP’s voting power .
  • LGP designee: Seiffer is an LGP Designee under the Stockholders Agreement, which grants LGP director nomination and committee composition rights—an important governance consideration .
  • Attendance and engagement: In 2024, the Board met 4 times; Audit 8; Compensation 4; Nominating & Corporate Governance 4. Each director attended at least 75% of meetings, and all attended the 2024 annual meeting .
  • Independent director executive sessions occur regularly with a rotating presiding director among independents .

  • LGP affiliation carve‑out: “Non‑employee directors affiliated with LGP are not compensated for their director responsibilities” (i.e., Seiffer does not receive cash retainers or RSU grants under the policy) .

Governance Assessment

  • Positives

    • Independent director status; active governance roles (Chair of Nominating & Corporate Governance; member of Compensation Committee), indicating strong influence over board refreshment, governance guidelines, and executive pay oversight .
    • No director compensation (cash or equity) due to LGP affiliation—reduces pay‑related conflicts and avoids short‑term equity incentives misaligning long‑term oversight .
    • Robust governance infrastructure: independent director executive sessions; related‑party transaction policy; Audit Committee approval of related‑party transactions; independent comp consultant (Exequity) with no conflicts in 2024 .
  • Risks and RED FLAGS

    • Controlled company risk: LGP controls 66.1% and holds nomination/committee composition rights via Stockholders Agreement; Seiffer is an LGP Designee—potential influence concentration and perceived conflicts despite formal independence .
    • Limited personal share ownership disclosure (—, <1%) may reduce “skin‑in‑the‑game” signals at the individual level; alignment is predominantly via sponsor ownership rather than direct holdings .
    • The Board may choose to avail controlled company exemptions in the future, potentially weakening independence safeguards (currently compliant) .
  • Engagement signals

    • Meeting attendance at or above 75% and full annual meeting attendance demonstrate baseline engagement; leadership of the Nominating & Corporate Governance Committee suggests active board process oversight .

Overall, Seiffer’s deep private equity experience and committee leadership are strengths for board effectiveness; the principal governance consideration is LGP’s concentrated control and designation rights, which necessitate vigilant enforcement of independence standards and related‑party transaction policies to sustain investor confidence .
