About Mahkam Zanganeh

Mahkam Zanganeh, age 54, is Co-Chief Executive Officer, President, and a director of Summit Therapeutics; she joined the Board in November 2020, served as COO from November 2020 to July 2022, and has been Co-CEO and President since July 2022. She holds a DDS (Louis Pasteur University, Strasbourg) and an MBA (Schiller International University), and has prior senior operating roles at Pharmacyclics and Computer Motion as well as experience in business development and government-backed biotech cluster leadership . Summit reports that it is a development-stage, pre-revenue biopharma and does not link NEO compensation to traditional financial metrics; net losses were $(88.6)M in 2021, $(78.8)M in 2022, $(614.9)M in 2023, and $(221.3)M in 2024, while Company TSR (value of $100 invested 12/31/2020) moved from $57 in 2021 to $380 in 2024, highlighting significant stock-driven value creation in 2024 rather than P&L fundamentals .

  • April 2025 modification: Dr. Zanganeh consented to modify outstanding unvested 11,030,558 performance-based stock options (granted Jun 2022–Oct 2023) so that 50% vested immediately upon consent; remaining 50% vests in three annual tranches beginning October 2025, eliminating the need to meet performance conditions going forward (service-based only) .
  • 2023 awards included two 11,988,198-option tranches: one time-based (4-year vesting) and one with revenue/market-based conditions; a market condition was met in 2024, vesting 2,397,640 options .
  • 2022 performance-based grant of 1,800,000 options (separate from table presentation) recognized 360,000 vested in 2024 upon achieving a market condition; GDFV of vested portion $307,200 .

Pay versus performance linkage:

  • Company states it does not use financial performance measures for NEO CAP and relies on non-financial OKRs; CAP rose with stock price appreciation in 2024 .

Board Governance

  • Board service history: Director since Nov 2020; executive director (management) and thus non-independent under Nasdaq rules .

  • Lead Independent Director: Kenneth A. Clark .

  • Attendance: Board held 2 meetings in 2024; each director attended at least 75% of Board/committee meetings during their service periods; all current directors attended the 2024 annual meeting .

Director Compensation

  • Employee directors (including Dr. Zanganeh) receive no incremental board retainers/equity for director service; non-employee director program includes cash retainers and annual/new director option grants; non-salaried directors could convert cash fees to options via a “Retainer Option Election” .

  • Delegation: Prior disclosures note delegation to CEOs to grant a capped amount of options under the plan (historical 2024 proxy detail) .
  • Say-on-Pay: 2024 advisory vote received ~97% approval; no material program changes based on that outcome .

Board Service, Roles, and Dual-Role Implications

  • Service history: Director since 2020; Co-CEO/President since 2022 .
  • Committee roles: None; not listed as a member of Audit, Compensation, or Nominating committees .
  • Independence: As a management director and spouse of controlling shareholder, Dr. Zanganeh is not independent; Summit is a Nasdaq “controlled company,” allowing exemptions from certain independence requirements .
  • Governance implications: Concentrated control (Mr. Duggan), executive-director dual role, and family relationship increase perceived governance risk; counterbalanced by presence of a Lead Independent Director (Clark) and independent committee compositions .

Investment Implications

  • Alignment and upside leverage: Very large in-the-money option exposure (exercise prices ~$1.06–$1.68 vs $17.84 at 12/31/24) and 6.6% beneficial ownership align incentives to long-term equity value creation; 2025 modification time-bases previously performance awards, ensuring retention-linked vesting through 2027 .
  • Near-term selling pressure risk: April 2025 immediate vesting of ~5.5M options and scheduled annual tranches beginning Oct 2025 create recurring potential liquidity windows; monitor Form 4s for 10b5-1 plan activity and sales around vest dates .
  • Pay-for-performance and governance red flags: Use of 280G excise tax gross-up and substantial CIC acceleration value (> $440M estimate) are shareholder-unfriendly; 2025 modification reduced performance rigor by removing performance conditions on a significant award pool .
  • Execution focus over financials: Bonus metrics tied to clinical, regulatory, and operational OKRs (not revenue/EBITDA), consistent with pre-revenue status; 2024 TSR surge drove compensation “actually paid” rather than traditional financial performance, increasing sensitivity to stock volatility .
  • Board structure: Controlled company status, executive-director dual role, and spousal relationship to the controlling shareholder raise independence concerns; independent committees and a Lead Independent Director partly mitigate .
  • Shareholder sentiment: Strong 2024 say-on-pay support (~97%) indicates current investor tolerance for structure, but large CIC payouts and reduced performance conditions could become flashpoints if clinical/operational progress falters or if sizable insider sales occur .
