About Barbara McClung

Barbara G. McClung, J.D., is Chief Legal Officer and Corporate Secretary at Caribou Biosciences (CRBU), a role she has held since April 2015; she is 70 years old as of April 15, 2025, and is a registered patent attorney admitted in CA/DE/PA, with B.A. (UC San Diego), M.A. (University of Pennsylvania), and J.D. (University of Pennsylvania Law School). She teaches biotechnology law at UC Berkeley School of Law and has over three decades of biotechnology industry legal leadership across IP, corporate, and governance roles . Operating performance context: CRBU remains a clinical-stage biotech with modest collaboration revenue and negative EBITDA; revenue declined from FY2023 to FY2024 and losses expanded, consistent with an R&D-heavy profile (see financial table below; values from S&P Global). CRBU does not conduct say‑on‑pay votes as an EGC, limiting direct shareholder feedback on executive pay .

Observations: 2024 equity tilted toward options with supplemental RSUs; forfeiture of 2022 PSUs indicates stretch performance calibration; vesting cadence (monthly for options, annual for RSUs) creates periodic liquidity windows but company policy prohibits hedging and pledging .

Additional Governance and Compensation Design Notes

  • Compensation oversight and governance: Compensation committee (with Pay Governance as independent advisor) reviews executive pay, goals, severance terms, and clawback policy .
  • Equity plan change‑in‑control features: Under the 2013 and 2021 equity plans, awards may be assumed, accelerated, cashed-out, or terminated depending on deal structure; the 2021 Plan permits accelerated vesting if not assumed or upon post‑deal termination per administrator discretion .
  • Say‑on‑pay: As an EGC/smaller reporting company, CRBU has elected not to hold say‑on‑pay or frequency votes at this time .

Investment Implications

  • Pay-for-performance alignment: McClung’s variable pay reflects company-wide outcomes (87.5% of target in 2024, 100% in 2023), and 2022 PSUs were forfeited when a clinical milestone was missed—signals performance calibration and some discipline on equity payouts .
  • Retention risk vs. selling pressure: Significant unvested/options outstanding (275,203 unexercisable options and 33,000 RSUs at 12/31/2024) provide retention hooks; vesting cadence (monthly options, annual RSUs) creates episodic liquidity windows, but company policy eliminates hedging/pledging, reducing misalignment risk .
  • Change‑of‑control economics: Double‑trigger protection (12 months base, 1.0x target bonus, full time‑based equity acceleration) is standard for biotech NEOs; not excessive vs peers and mitigates deal‑completion friction while preserving alignment .
  • Ownership alignment: Beneficial ownership of 907,545 shares (<1%) plus long‑tenure and prohibition on pledging supports alignment; no disclosed ownership multiple guidelines may be a neutral or minor gap .
  • Execution considerations: Legal/IP continuity under a veteran biotech CLO supports CRBU’s partnering, clinical/IP strategy, and disclosure rigor during pivotal program milestones; however, company remains loss‑making and reliant on pipeline maturation and external funding, which constrains absolute pay-for-performance optics (see financials; S&P Global).
