The bulk is conditional. The deal links future required capital to certain certification and design points. The initial funding piece locks on more agreements and the critical design review. After that, FAA Type Inspection Authorization is the next trigger. The final one is type certification. Toyota and Joby still have to finalize the total amount.
This matters for investors because the deal doesn’t bring a big new cash injection for Joby right now. According to Toyota’s amended Schedule 13D, setting up the stockholders agreement and the JV on their own do “not alone” meet the requirements for Toyota’s second tranche investment under the previous stock purchase agreement. Toyota also disclosed it owns 128.5 million Joby common shares, or 13.1% of shares outstanding. Joby Aero, Inc.

Joby’s high short interest means certification dates hit harder. As of June 15, shorts held 100.74 million shares. On Wednesday, trading volume was about 46% of that, or more than twice Wednesday’s volume would be needed to cover all outstanding shorts.
Joby has cash to work with, but that only goes so far. The company finished Q1 holding $2.5 billion in cash, cash equivalents, and short-term investments. With a market cap near $8.77 billion on Wednesday, that’s about 29% of its total value in cash.
Joby said in May its first FAA-conforming aircraft flew in the first quarter and that it finished the SR3 audit, which is the third of four big FAA certification checks. Composites output was over 2.5 times higher than last year, and Ohio capacity rose to almost 1.5 million square feet.
The NYSE will close for Independence Day on Friday, July 3, 2026, according to the official calendar. Wednesday trading ran as usual, so only Thursday remains open before the holiday.
