Joby Aviation Agrees to Buy Resonant Sciences for $500 Million to Expand Defense Business
Joby Aviation agreed to buy Resonant Sciences for $500 million, with consideration in cash and stock, to expand its defense business. Resonant, based in Ohio, makes radio-frequency and sensor systems and will become a separate defense division led by CEO J. Micah North. Resonant reported $100 million revenue over 12 months and works on classified U.S. programs.
How this was made

The 30-second read
Why it matters
Acquiring Resonant Sciences adds radio-frequency and sensor systems plus an existing revenue base and classified government programs, potentially improving defense credibility while Joby continues eVTOL certification and production ramp efforts.
Market read
A $500 million cash-and-stock acquisition is a fresh M&A catalyst that can shift valuation expectations for Joby’s defense revenue and technology roadmap.
What to watch
Financing terms, regulatory/DoD contracting timelines for classified work, and whether Resonant’s revenue is durable post-acquisition are not detailed here.
Background
Joby is developing electric air taxis and has been building defense-related aircraft and autonomy capabilities, including work tied to turbine-electric and hydrogen-electric propulsion concepts.
Ticker impact
Joby Aviation agreed to buy Resonant Sciences for $500 million, expanding its defense business via a new defense division.
Likely positive near-term on M&A expansion narrative, but expect volatility tied to integration and financing assumptions.
The article discloses deal size, structure (cash and stock), and strategic rationale (radio-frequency/sensors plus classified programs), which are typically market-moving for growth-stage aerospace names.
Market effects
Highlights consolidation in eVTOL and defense-adjacent avionics, potentially increasing competitive focus on sensors and RF systems.
Resonant’s Ohio footprint may strengthen regional defense-tech supply chain relevance.
Defense technology demand and classified program access can influence investor perception of US aerospace defense spend durability.
Counterpoint
Stock may discount the deal as dilutive or execution-heavy if the stock component is large and integration distracts from eVTOL certification and scaling.
