Who should consider this stock?
JOBY may suit investors who:
- →believe Joby's furthest-advanced FAA certification progress and 1,000+ test flights provide the most credible path to commercial eVTOL operations among publicly traded air taxi companies
- →value Toyota's manufacturing expertise partnership as a uniquely valuable capability for transitioning from handcrafted test aircraft to mass-produced commercial air taxis at automotive quality standards
- →see Delta Air Lines' airport access and customer relationships as the premium launch market that validates Joby's urban air taxi service will have initial commercial demand at scale
- →are comfortable with pre-revenue burns, FAA certification timeline uncertainty, and the inherent risks of a novel aviation category requiring unprecedented regulatory approval
ACHR may suit investors who:
- →prefer Archer's United Airlines launch customer providing a committed commercial partnership for the specific Manhattan-Newark route — one of the world's busiest urban air corridors
- →value Stellantis manufacturing partnership bringing automotive-scale production expertise complementary to Joby's Toyota partnership — both provide similar strategic manufacturing value
- →see Archer's DoD reconnaissance contract as meaningful near-term revenue diversification reducing pure commercial certification dependency

| Company | Joby Aviation, Inc. | Archer Aviation Inc. |
| Sector | Urban Air Mobility | Urban Air Mobility |
| Industry | N/A | N/A |
| Core business | Joby Aviation is an electric vertical takeoff and landing (eVTOL) air taxi company developing a 5-seat aircraft capable of 150+ mph speeds and 150+ mile range on a single charge. Joby is widely considered the most advanced US eVTOL company with FAA certification progression, manufacturing investment, and partnerships including Toyota (manufacturing expertise, investment) and Delta Air Lines (airport access, launch market partnership). Joby's aircraft has completed 1,000+ test flights. The company targets commercial air taxi operations starting in 2025-2026 following FAA type certification. | Archer Aviation is an eVTOL air taxi company developing the Midnight aircraft — a 5-seat tilting-rotor design targeting 60-mile range with 1.5 hour recharge between flights. Archer has a significant partnership with United Airlines (launch customer for urban air taxi service from Newark to Manhattan) and a manufacturing partnership with Stellantis for production scale-up. Archer has completed initial test flights and is pursuing FAA type certification. The company also has a defense contract for an eVTOL reconnaissance mission system. |
| Investor focus | Investors track Joby's FAA type certificate application milestones, manufacturing scale-up at its Santa Cruz facility, Delta partnership airport deployment plans, and certification timeline against competitors. | Investors track Archer's FAA certification milestones, United Airlines launch market deployment, Stellantis manufacturing partnership production ramp, and DoD contract execution. |
JOBY strengths
- →Most advanced FAA certification progress: Joby has the furthest advanced FAA Part 135 air carrier and type certificate applications among public eVTOL companies — regulatory progress is the key bottleneck for commercial service
- →Toyota manufacturing expertise partnership: Toyota's investment and manufacturing guidance is uniquely valuable for transitioning from flight test vehicles to mass-produced air taxis — automotive manufacturing knowledge transfer is critical
- →Delta Air Lines airport partnership: Delta's existing airport infrastructure, terminal access, and customer relationships provide Joby with premium launch market access for its air taxi service
ACHR strengths
- →United Airlines launch customer partnership: United Airlines' commitment to purchase Archer air taxi operations for Manhattan-Newark routes provides a validated commercial launch customer and premium market entry point
- →Stellantis manufacturing partnership: automotive manufacturing expertise from Stellantis addresses the key operational challenge of scaling from prototype to mass production aircraft
- →Defense contract diversification: Archer's DoD reconnaissance eVTOL contract provides government revenue while commercial FAA certification progresses — reducing pure commercial aviation dependency
Risks to watch — JOBY
- →FAA certification timeline is uncertain: FAA type certification for eVTOL aircraft is unprecedented — the regulatory timeline may extend significantly beyond Joby's projections, delaying revenue
- →Massive capital requirements before commercialization: Joby needs billions to complete certification, manufacture aircraft, and build operations — pre-revenue capital burn is substantial
- →Weather and range operational limitations: Joby's eVTOL operates in specific weather conditions and has range limitations that constrain the market it can initially serve — urban air taxi is more weather-dependent than traditional aviation
Risks to watch — ACHR
- →FAA certification timeline similar uncertainty to Joby: Archer's FAA certification faces the same novel regulatory timeline uncertainties as all eVTOL companies — timeline delays are the primary risk
- →Less advanced FAA certification than Joby: Joby has more accumulated FAA certification progress and test flight hours — Archer is behind Joby on the regulatory timeline
- →Battery recharge time limits mission frequency: Archer's 1.5-hour recharge requirement limits the number of flights per aircraft per day — operational economics depend on improving battery charging speed
