Equity Ownership

Michael Fosnaugh
Vista Funds (aggregate)65,010,001 40%
  • IAS prohibits hedging and pledging by directors, officers, and employees under its Insider Trading Policy .

Governance Assessment

  • Strengths: Independent Chair with separated CEO/Chair roles; formal risk oversight and cybersecurity oversight via Audit Committee; independent board/committee composition and annual self-evaluation processes; clear anti-hedging/anti-pledging and clawback policies .
  • Potential conflicts/RED FLAGS:
    • Vista control rights (nomination, committee proportion, board size changes require Vista consent) create structural influence; five Vista-affiliated directors (including Fosnaugh) heighten interlock considerations .
    • Related-party interactions: consulting with Vista Consulting Group (payments reimbursed) and registration rights; IAS paid ~$1.8M of offering-related costs for Vista’s secondary offering (excluding underwriting fees), and incurred ~$33,000 in expenses related to Vista services in 2024 .
    • Ownership alignment: Fosnaugh reports no personal beneficial ownership; Vista funds collectively own 40%—alignment may be primarily through sponsor ownership rather than personal holdings .
  • Attendance/engagement: Each director met the ≥75% attendance threshold in 2024; Board held 8 meetings, indicating active cadence .

Note on Director Compensation disclosure: IAS presents compensation only for non-employee, non-Vista-affiliated directors; Vista-affiliated director compensation (including Fosnaugh) is not disclosed in the reported director compensation table/policy .
