How this was made
The 30-second read
Why it matters
By making Resonant its dedicated defense business, Joby gains RF and mission systems plus hybrid aircraft and autonomy technologies, while keeping commercial operations focused on electric air taxis.
Market read
A $500 million acquisition with a defined funding mix and a 1H 2027 close window is a concrete catalyst for Joby’s valuation and risk outlook.
What to watch
Investors may underweight how the $50 million stock component affects dilution and how much of Resonant’s revenue is tied to specific national security programs that could be re-bid.
Background
Joby is an eVTOL company pursuing both commercial air taxi initiatives and a growing defense market.
Ticker impact
Joby Aviation will buy Resonant Sciences for about $500 million, funding with $450 million cash and $50 million stock, targeting close in 1H 2027.

Market effects
