Employment Terms
- Employment agreement effective January 6, 2023; base salary $666,750 (2024) and target bonus 60%; requires at least 70% of working time devoted to HilleVax .
- Severance (outside change‑in‑control): 12 months base salary; pro‑rated target bonus for year of termination plus any unpaid prior year bonus; COBRA subsidy during severance period; vesting acceleration for awards scheduled to vest during severance period (Founders’ shares governed separately) .
- Severance (within 24 months after a change‑in‑control, i.e., double trigger): 18 months base salary; target bonus for year of termination plus any unpaid prior year bonus; full vesting acceleration of all unvested equity (Founders’ shares per separate agreement) .
- 280G “best‑pay cap” applies to maximize after‑tax value if excise taxes would otherwise apply .
- Retention bonus letter (March 25, 2025): $500,063 payable if a change‑in‑control occurs on or before March 31, 2026 and he remains in service through closing; also payable upon certain qualifying terminations prior to payment (without cause, death/disability, or resignation for good reason) subject to release .
- Clawback policy adopted consistent with SEC/Nasdaq rules (applies to Section 16 officers) .
Board Governance
- Dual role: CEO and Chairman; board has appointed a Lead Independent Director (Patrick Heron) with defined authorities (chairs executive sessions of independent directors, reviews agendas/materials, facilitates board‑CEO communication, consults on governance and performance) .
- Independence: Board determined that all directors except Drs. Hershberg and Kohli are independent under Nasdaq rules .
- Board/Committees: Audit (Chair: Jeryl Hilleman), Compensation (Chair: Julie Gerberding), Nominating & Corporate Governance (Chair: Patrick Heron) .
- Attendance: Board met 16 times in 2024; each director attended at least 75% of applicable meetings/committees .
Performance & Track Record (selected)
- Pipeline outcome: Phase 2b NEST‑IN1 in infants (HIL‑214) failed primary endpoint and showed no benefit on secondary endpoints in July 2024; safety/immunogenicity consistent with prior data .
- Strategic options: Company disclosed it is exploring development paths and business‑development or strategic alternatives for vaccine candidates following the NEST‑IN1 outcome .
Compensation Structure Analysis
- Mix shift and risk: Pay heavily equity‑oriented via multi‑year RSU and option grants (2023–2024), aligning with long‑term outcomes; no 2024 cash bonus was paid, indicating downward pay sensitivity to results .
- Time‑vesting equity predominates; no disclosed formulaic performance equity metrics (e.g., TSR/EBITDA) in 2023–2024; as an EGC, detailed metric disclosure is limited .
- CIC economics: Double‑trigger equity acceleration plus 18‑month cash and target bonus can be shareholder‑friendly relative to single‑trigger structures; however, the 2025 retention bonus tied to a CIC is an incremental sale incentive .
- Governance mitigants: Anti‑hedging/anti‑pledging policy and clawback policy reduce misalignment and risk behaviors .
Vesting Schedules and Potential Selling Pressure
- Near/medium‑term vesting events (time‑based):
- Founders’ restricted stock monthly vesting completed on February 8, 2025 .
- RSUs (2/1/2023) vest 25% annually through 2027; RSUs (2/8/2024) vest annually through 2028 .
- Options (2/1/2023) and (2/8/2024) vest per 1‑year cliff then monthly thereafter (strikes $18.00 and $15.06, expirations 2033 and 2034) .
- Insider trading policy: Pledging/hedging banned; standard BOD/Section 16 trading controls apply; Section 16 compliance note for 2024 listed late Form 4s for some directors—not naming Hershberg .
- Form 4 flow: Our document index shows no Form 4s available via this system for HLVX; we could not quantify recent net selling/buying pressure from filings in this environment [ListDocuments: type 4 returned none].
Director Compensation (as applicable to dual role)
- As an employee director (CEO/Chair), Hershberg receives no additional director compensation; non‑employee director retainer/option program is separate .
Related‑Party/Conflicts Snapshot
- Major holders: Entities affiliated with Frazier Life Sciences (Heron/Topper) and Takeda are significant shareholders; Hershberg is a Venture Partner at Frazier (since 2020). The proxy details Frazier/Takeda ownership and Takeda licensing/TSAs; no specific related‑party transaction is attributed to Hershberg individually in the disclosures cited here .

Investment Implications
- Alignment and retention: Large time‑vested equity grants and substantial unvested holdings align CEO with long‑term equity value; anti‑hedging/pledging and clawback strengthen alignment controls .
- Sale incentive vs. governance mitigants: The March 2025 CIC‑contingent retention bonus ($500,063) and double‑trigger CIC acceleration create incentives around strategic alternatives; the Lead Independent Director structure, independent committees, and EGC status mitigate—but do not eliminate—dual‑role risks .
- Execution risk: The failed NEST‑IN1 primary endpoint in 2024 materially elevates program and funding risk; lack of 2024 bonuses reflects pay sensitivity to results, but forward value creation depends on re‑design/BD outcomes .
- Trading signals: Without visible Form 4 flow here, near‑term selling pressure is most likely tied to scheduled RSU/option vesting and potential liquidity needs; policy prohibits pledging/hedging, reducing risk of forced selling .
