Other Directorships & Interlocks

CompanyRoleInterlock/Conflict Consideration
Maravai LifeSciences (MRVI)Director MRVI was added to SHC’s 2024 compensation peer group, creating a potential benchmarking interlock, though Cunningham is not on the LDC Committee that sets pay .

Potential conflict signal: Peer group includes a company where a sitting SHC director serves, which can raise perceptions of influence on benchmarking; however, LDC membership (Neary–Chair, Mihas, Simon) excludes Cunningham and Audit Committee independence is heightened (no sponsor designees) .

Expertise & Qualifications

  • Finance and strategy expertise; healthcare/medtech experience; international exposure; legal/regulatory familiarity; service on other public company boards (count 1) .
  • Selected for “decades-long investment practice” and extensive industry knowledge .

Governance Assessment

  • Independence and committee work: Independent director with active roles on governance (NCG) and specialized committees (EO Litigation, Nordion Pricing), signaling engagement on litigation risk and commercial conflict management .
  • Sponsor affiliation and rights: Affiliated with GTCR; GTCR retains designation rights and committee representation proportionate to board seats; sponsor-designated directors are excluded from Audit, mitigating financial reporting conflicts . RED FLAG: Sponsor registration rights enable large secondary sales and influence board composition; removal of directors requires 75% vote for cause, and the board remains classified, which can entrench governance .
  • Compensation alignment: Director pay mix is modest cash + time-based equity; ownership guidelines require meaningful holdings; hedging prohibited—positive for alignment .
  • Shareholder signals: Say-on-pay received >98% approval in 2024; compensation program adjustments in 2025 increased performance-based incentives for executives, reflecting responsiveness to investors (contextual governance signal) .
  • Attendance and engagement: Board met eight times; committees met frequently; all directors attended the 2024 Annual Meeting—no attendance concerns disclosed .

Related Party & Conflict Considerations

  • Registration Rights Agreement allows Warburg Pincus and GTCR to demand registrations and conduct marketed offerings, with multiple secondary sales executed in 2024; company no longer a “controlled company” post-September 2024 offering .
  • Stockholders Agreement confers designation rights to sponsors (current holdings keep rights in force); sponsor representatives on committees except Audit; Warburg can appoint LDC Chair while entitled to designate at least one director .
  • EO Litigation and Nordion Pricing committees formed to manage sensitive litigation and customer confidentiality, reducing cross-business conflicts; Cunningham sits on both .
