Equity Ownership

DetailAmount
Total beneficial ownership612,078 shares; 1.5% of outstanding shares
Directly held by J. Knowles1,191 shares
Options exercisable within 60 days (included above)36,586 shares
Held by Partners Innovation Fund, LLC (PIF I)341,574 shares
Held by Partners Innovation Fund II, L.P. (PIF II)232,727 shares

Notes and alignment/risk controls:

  • As a partner of the Partners Innovation Fund general partners, Mr. Knowles may be deemed to share voting and investment power over PIF I and PIF II holdings; beneficial ownership table aggregates these interests with his personal holdings/options .
  • Company policy prohibits hedging and pledging of Keros stock by directors .

Governance Assessment

  • Strengths for investor confidence

    • Independence affirmed; serves on Audit and Nominating & Corporate Governance—key oversight committees; Board uses executive sessions and has a Lead Independent Director, supporting effective independent oversight .
    • Attendance: met the company’s standard (≥75%) alongside peers in 2024; engaged across 9 Board meetings; Audit (4) and N&CG (6) meetings indicate active committee cadence .
    • Equity-heavy director pay (2024: $321,099 options vs. $52,500 cash) aligns director incentives with long-term shareholder value; pay is within the $500,000 annual cap .
  • Potential conflicts and mitigants

    • Fund affiliation: Partners Innovation Fund entities collectively hold a significant Keros stake; as a fund partner, Mr. Knowles may be deemed to share voting/dispositive power—this can raise perceived conflicts on capital allocation, M&A, or strategic reviews; mitigants include Nasdaq independence determination, committee independence, and a formal related-party transaction policy overseen by the Audit Committee .
    • Multiple investor-affiliated directors on the Board (e.g., Pontifax designees) increase the importance of recusals and robust N&CG oversight of independence and conflicts; the N&CG charter explicitly covers independence and conflicts review .
  • Compensation structure observations

    • Non-employee director compensation is predominantly time-vested stock options with CIC acceleration; no performance metrics tied to director pay, consistent with small/mid-cap biotech norms; hedging/pledging prohibited; clawback policy maintained for incentive compensation (primarily relevant to executives) .
  • RED FLAGS to monitor

    • Related-party exposure via affiliated fund holdings (PIF I, PIF II); ensure recusals on any matters uniquely affecting those investors and continued Audit Committee oversight under the related-party policy .
    • Change-in-control full vesting for director options can create perceived incentives around deal timing; however, this is disclosed and bounded by annual director pay caps .
