Joby Aviation shares rose 6.3% in pre-market trading after a regulatory filing on June 29, 2026, revealed that Joby and Toyota Motor Corporation have formed a new Delaware manufacturing vehicle called Joby Toyota Aero Manufacturing Preparation Company, or JTAMPC. The document sets out an ownership arrangement in which Toyota controls 51% of the new entity and appoints three of its five board directors; Joby retains a 49% stake and designates the remaining two directors.
The filing builds on an existing collaboration that has included roughly $894 million of Toyota commitment to Joby over several years and the placement of dozens of Toyota engineers inside Joby’s production operations. By creating a stand-alone manufacturing company, both firms are making an explicit move toward larger-scale production of Joby’s S4 Series eVTOL aircraft.
That shift toward a dedicated production platform has particular resonance given Joby’s regulatory status. The company is currently in Stage 4 of the Federal Aviation Administration’s five-stage type certification process and continues to target initial commercial operations under the White House’s eVTOL Integration Pilot Program later this year. For investors watching certification milestones, the formation of JTAMPC offers a tangible sign of progress from prototype work to preparations for serial manufacturing.
Financially, Joby entered the quarter with about $2.5 billion in cash and short-term investments, a balance that the company says reduces near-term dilution concerns. That liquidity position, combined with the Toyota-backed manufacturing arrangement and the company’s proximity to regulatory approval, provided a clear rationale for buying interest in the stock during pre-market trading.
The broader market backdrop also supported the move. U.S. equities were trading higher, with the S&P 500 up 1.2%, the Nasdaq rising 2.1%, and the Dow climbing 0.6% amid a rebound in technology names and hopes for a potential de-escalation of Middle East tensions. That risk-on environment tends to benefit high-beta growth companies like Joby, which carries a beta well above the market average and can therefore amplify sectorwide sentiment shifts.
Competitor Archer Aviation, which is also pursuing FAA certification, did not report any material developments today and has not announced a comparable manufacturing partnership. Taken together, the newly formalized Toyota-backed manufacturing joint venture, Joby’s advanced position in the FAA process, and the company’s sizable cash holdings provided investors with a concrete explanation for the pre-market uptick in the shares, with the move further amplified by a generally constructive session across U.S. equity markets.
