FAA certification delays or failure to achieve Part 23 type certification could push commercial operations beyond 2026, exhausting capital runway and requiring dilutive financing
Battery technology limitations preventing achievement of 150-mile range with full passenger load or requiring costly mid-life upgrades as solid-state technology matures
Vertiport infrastructure development lagging aircraft availability, limiting addressable markets to handful of cities with existing heliport infrastructure
Public acceptance and safety perception following any eVTOL industry incident, particularly given zero-accident tolerance in early adoption phase
Regulatory framework evolution imposing unexpected operational restrictions on urban air mobility (noise ordinances, flight path limitations, pilot requirements)
Archer Aviation and Vertical Aerospace achieving FAA certification simultaneously or earlier, eliminating first-mover advantage in key markets like New York, Los Angeles, San Francisco
Traditional aerospace incumbents (Boeing, Airbus, Embraer) entering eVTOL market with superior capital resources and regulatory relationships
Chinese manufacturers (EHang, AutoFlight) achieving commercial scale in Asia-Pacific markets and leveraging cost advantages for global expansion
Ground transportation alternatives (autonomous vehicles, hyperloop) achieving faster regulatory approval and comparable trip economics
Cash burn of $400M+ annually with $5.2B cash position implies 3-4 year runway, requiring additional capital raise before profitability absent accelerated commercialization
Equity dilution risk from future financing rounds, PIPE investments, or convertible debt issuance to fund manufacturing scale-up and initial fleet deployment
Warrant overhang from SPAC merger creating selling pressure as milestones are achieved and lockup periods expire
Contingent liabilities from manufacturing defects or safety incidents could require costly recalls or design modifications pre-certification
