Fixed Compensation

  • CGEM’s 2024–2025 proxies disclose Named Executive Officer (NEO) compensation for the CEO, CFO, CMO, and former CFO; Dr. Michaelson (CSO) was not an NEO in these filings, so her base salary, target bonus, and actual bonus amounts are not disclosed.

Performance Compensation

  • CGEM’s plan provides annual bonuses tied to pre-defined Company and individual performance metrics and equity incentives (options and RSUs) with multi-year vesting to promote retention and alignment; however, award metrics/weights for Dr. Michaelson are not individually disclosed.

Equity Ownership & Alignment

  • Principal stockholder tables enumerate directors and NEOs; Dr. Michaelson is not listed individually. Executives and directors as a group owned 7.16% as of April 1, 2025 (58,698,919 shares outstanding). No pledging by Dr. Michaelson is disclosed.
  • Insider trading/hedging policy: prohibits derivative transactions and purchases of derivative securities that provide the economic equivalent of ownership; it highlights pledging/margin risks.
  • Insider activity reference: a late Section 16(a) Form 4 was filed for Dr. Michaelson reporting the sale of 238 shares on March 20, 2023 (filed March 27, 2023).

Equity plan/vesting context

  • Under CGEM’s 2021 Stock Plan, executive equity awards typically vest over multi-year schedules (e.g., options vest monthly over 48 months; RSUs vest in four annual installments), reinforcing retention; Dr. Michaelson’s specific grants/vesting are not itemized in the 2023–2025 proxies.

Employment Terms

  • Executive officers (non-directors) biographies indicate no arrangements/understandings for officer selection and no material legal proceedings involving executive officers.
  • Employment agreements are described for NEOs (not specific to Dr. Michaelson), including base salary, target bonus, confidentiality, and one-year post-termination non-solicitation; severance and double-trigger change-in-control equity acceleration are features in NEO agreements. Michaelson’s specific employment agreement terms are not disclosed.
  • Compensation committee (independent; advised by Compensia) oversees pay, grants, and clawback policy administration.

Investment Implications

  • Alignment and retention: Michaelson’s progression from VP (2018) to CSO (2023) provides continuity across discovery-to-development; CGEM’s equity program is designed with multi-year vesting, which generally mitigates near-term attrition risk for senior R&D leaders. Specific CSO grant data are not disclosed, limiting precision on overhang and vesting-driven sell pressure.
  • Trading signals: The only proxy-noted insider activity is a small 238-share sale in March 2023 associated with a late filing—too small to infer sustained selling pressure, but useful to monitor through ongoing Form 4s.
  • Governance/risk: Company prohibits derivatives/hedging and highlights pledging risks, reducing misalignment concerns; the comp committee’s use of an independent consultant and clawback oversight further supports pay governance. Lack of CSO-specific disclosure (not an NEO) reduces transparency into incentive metric rigor and severance economics at the individual level.
  • Performance context: Company TSR improved from 2023 to 2024 while net losses persisted, underscoring the biotech profile where value creation hinges on clinical execution; execution risk remains tied to advancing pipeline programs under Michaelson’s scientific leadership.
