Governance Assessment

  • Strengths: Independent director with deep oncology expertise; active on Commercialization & Portfolio Committee; attendance ≥75% indicates engagement; robust equity plan governance (no repricing; minimum vesting; clawback; double-trigger CIC) .

  • Alignment: 2024 compensation mix emphasizes equity options alongside cash retainer; pro‑rated option grant and outstanding options support long‑term alignment, though current beneficial ownership is modest (<1%) .

  • Watch items (potential RED FLAGS): Multiple external commitments (CEO at Marengo; boards at CytomX and Galvanize) may create time‑allocation risk; sector overlap with oncology peers could represent potential informational conflicts, though no related‑party transactions are disclosed and independence is affirmed . No Form 4 insider trading data available in tool results to assess recent trading behavior [List: Form 4 none].

  • Director compensation policy changes: Equity option grants for non‑employee directors increased in March 2024 (annual from 2,266 to 4,600; initial from 4,533 to 9,200), signaling greater equity emphasis for director alignment .

Insider trades: No Form 4 filings were found for KPTI during the search, so recent insider transaction details for Dr. Su were not available in tool results (searched Form 4 catalog) [ListDocuments: Form 4 none].
