Joby Aviation slides 5% on Resonant Sciences $500M acquisition

Joby Aviation announced it will acquire defense technology company Resonant Sciences for about $500 million, a move that expands Joby’s defense business beyond commercial air taxis. The company says Resonant provides an established, EBITDA-positive platform already serving U.S. national security programs. Strategically, the deal broadens Joby’s addressable market and combines its aircraft propulsion and autonomy technologies with Resonant’s defense capabilities, potentially improving revenue diversification and reducing reliance on the still-developing urban air mobility business. The article does not provide financing details, closing timing, or immediate financial impact, but the acquisition signals a meaningful shift toward defense as a growth driver for Joby.
