Board Governance
- Board service: Appointed a Class II director effective August 28, 2025; term through the 2026 annual meeting .
- Committees: 2024 Audit (Philip—Chair; Lauck; Lyne) and Compensation (Lyne—Chair; Affeldt; Lerer; Philip) and Nominating & Corporate Governance (Love—Chair; Affeldt; Borthwick) were composed of independent directors under Nasdaq rules . Executive directors typically do not serve on these committees to preserve independence.
- Meetings: In 2024, Board met 5x; Audit 4x; Compensation 5x; NCGC 2x; each director attended at least 75% of aggregate meetings; independent directors meet regularly in executive session .
- Board leadership: Company policy separates CEO and Chair; if Chair not independent, a lead independent director is designated; governance guidelines and committee charters available on IR site .
Director Compensation (Program; for non-employee directors)
| Role | Compensation |
|---|---|
| Director | RSU award of $150,000 and, at director’s election, $50,000 in either RSUs or cash |
| Board Chair | $50,000 in RSUs or cash (election) |
| Audit Chair | $20,000 in RSUs or cash (election) |
| Compensation Chair | $15,000 in RSUs or cash (election) |
| NCGC Chair | $10,000 in RSUs or cash (election) |
| Audit Member | $10,000 in RSUs or cash (election) |
| Compensation Member | $7,500 in RSUs or cash (election) |

FY2024 director RSUs (base award): 42,826 per continuing director; vest 100% at 2025 annual meeting; directors also eligible for Flight Benefit Policy; FY2024 individual director compensation amounts disclosed separately (non-employee directors only) .
Additional Disclosures Relevant to Compensation & Governance
- Peer group (adopted May 2023 with Aon): mix of aerospace/defense, airlines, and adjacent sectors; Blade was at 38th percentile of market cap and 41st percentile of revenue within peer group at time of analysis .
- Pay versus Performance (Company-level): Compensation Actually Paid and TSR disclosed; Non-PEO NEOs comprised Tomkiel and Heyburn for periods presented .
Investment Implications
- Pay-for-performance alignment: Heyburn’s 2024 pay was majority at-risk, with 100% of long-term equity in PSUs tied to profitability (Adjusted EBITDA), Free Cash Flow, and strategic EVA milestones; early achievement and certification of positive Adjusted EBITDA led to vesting of 20% of PSUs, signaling execution momentum .
- Potential selling pressure windows: RSU vesting cadence through 2025–2026 and further PSU vesting contingent on multi-year performance may create periodic liquidity events; however, robust anti-hedging/anti-pledging policies and ownership guidelines mitigate misalignment risk .
- Retention and CoC economics: Severance is moderate (1x base; prorated bonus during CoC window) with double-trigger equity protections and clawback compliance—supportive of retention without shareholder-unfriendly features (no excise tax gross-ups; no single-trigger) .
- Governance considerations: Dual role as Co-CEO, CFO, and director concentrates executive influence; committee independence and a separated Chair structure are intended to preserve oversight integrity; continued adherence to independent committee composition is key for governance quality .
