Joby Aviation and Toyota have formalized a joint venture to manufacture Joby's S4 electric air taxi, with Toyota holding a controlling 51% stake and securing exclusive production rights for the S4 series. The deal moves Joby's manufacturing ambitions from a startup model toward Toyota's industrial-scale automotive production infrastructure. This is a significant structural shift in how Joby plans to bring its aircraft to commercial scale.
For Joby shareholders, Toyota's 51% stake and exclusive production rights signal that a world-class manufacturer is betting its own capital and credibility on the S4 reaching mass production — reducing the execution risk that has weighed on the stock. However, Toyota's majority control means Joby cedes significant leverage over its own manufacturing destiny, which could compress future margins or limit strategic flexibility. Broader eVTOL-adjacent names like Archer Aviation could also see sentiment spillover as the deal validates the sector's commercial timeline.
