The Joby Aviation story
Joby Aviation is developing electric air taxis, with the central question of whether certification and manufacturing can turn Blade’s passenger network into a launch platform for its own aircraft.

The story in brief
- Certification remains unfinished. In the quarter to June 2026, Joby reported its strongest quarterly progress in the fifth and final stage of FAA Type Certification, but certification remained pending.
- Blade brings revenue. Blade generated $36.2 million in revenue in the quarter to June 2026, giving Joby an operating passenger business before its electric air taxi launch.
- Cash supports costly development. Joby held $2.3 billion in cash and short-term investments at the end of June 2026 and anticipated using between $385 million and $415 million in the second half of 2026.
What drives the business
- Joby’s strategy combines aircraft manufacturing with its own air taxi service, partner-operated services and direct aircraft sales, with Uber and Delta Air Lines partnerships intended to help connect travelers to its network.
- The August 2025 acquisition of Blade’s passenger business brought customers, operating experience and terminals in New York City and Southern Europe, providing infrastructure that Joby intends to use for electric air taxi service.
- Potential international aircraft business includes a memorandum of understanding with Abdul Latif Jameel exploring up to 200 aircraft and related services valued at approximately $1 billion, and a letter of intent with Alatau Advance Air Group covering aircraft and services valued at up to $250 million.
- In August 2026, Joby agreed to acquire Resonant Sciences for approximately $500 million to establish a dedicated defense business, adding a company with more than $100 million in trailing-twelve-month revenue from programs primarily serving the U.S. government, prime contractors and defense technology customers.
- Joby reported five aircraft flying and 12 more in production in the quarter to June 2026, while its Toyota joint venture is intended to support high-volume manufacturing and its Atoms partnership is intended to develop transportation hubs in U.S. launch markets.
What the price assumes
The reverse DCF cannot measure the growth implied by the $6.11 share price because free cash flow and operating earnings are both negative, leaving the valuation dependent on future profits.
Over the last twelve months, Joby generated $116 million in revenue but free cash flow was -$743 million, so an operating revenue base has not yet translated into cash generation.
Its 52.0x price to sales compares with the TenQ check’s bar of under 2.5x, while its -12.3% free cash flow yield falls short of the check’s above 3% requirement.
What could change the story
- FAA rules for electric air taxis are still evolving, and additional requirements could extend certification timelines even as Joby progresses through the final stage.
- The eIPP program permits selected operations ahead of full certification, so initial flights would not by themselves establish readiness for broader commercial service.
- Manufacturing expansion and international partnerships depend on production execution, definitive agreements, permits and approvals, rather than the announced opportunities alone.
- The -759.2% operating margin over the last twelve months shows how far revenue remains below operating costs, while $702 million in total debt adds obligations alongside development spending.
- Shares increased 41.1% over 3 years and stock-based pay totaled $170 million over the last twelve months, making dilution part of the cost of funding Joby’s expansion.
What to watch next
- The next releases will show whether the first Texas eIPP flights expected for September 2026 occurred and whether Joby remains on course to carry its first electric air taxi passengers in 2026, separately from completing FAA certification.
- Revenue will be measured against Joby’s raised 2026 outlook of $115 million to $125 million, with Blade’s contribution distinguishing established passenger operations from the electric aircraft launch.
- Cash use in the second half of 2026 will be measured against the $385 million to $415 million outlook, alongside aircraft completions and progress toward planned production of four aircraft per month in 2027.
- The closing status and funding of the approximately $500 million Resonant acquisition will clarify how the defense expansion changes Joby’s revenue mix and financial resources.
