Wowza — Joby Buys Defense Company For Half A Billion Dollars
Joby Aviation will buy defense technology firm Resonant Sciences for $500 million, according to Reuters. Joby plans to shift its defense programs, including hybrid and autonomous VTOL projects, under Resonant. Resonant provides radio-frequency and mission systems for U.S. national security customers. Joby expects to fund the deal with $450 million cash and $50 million stock; shares fell 6.5% premarket.
How this was made

The 30-second read
Why it matters
The acquisition consolidates Joby’s defense efforts under Resonant Sciences, potentially improving focus and pairing Joby’s commercial air-taxi mission with Resonant’s RF and mission systems.
Market read
Deal terms (price, funding, close timing) and the immediate premarket reaction provide a tradable catalyst for Joby around financing and execution expectations.
What to watch
Financing mix (cash plus common stock) can drive dilution concerns, and integrating Resonant’s systems with Joby’s hybrid/autonomy roadmap may introduce execution risk before any defense contract ramp.
Background
Joby is an eVTOL company that is increasingly emphasizing military markets as commercial timelines have lagged.
Ticker impact
Joby will buy Resonant Sciences for $500 million, moving its defense programs under Resonant and funding with $450M cash plus $50M stock.
Near-term volatility likely, with upside bias if investors view defense as a faster path to contracts; dilution risk may cap gains.
The article discloses deal size, funding mix, and expected close timing (H1 2027), plus a premarket drop of 6.5% that signals investors are weighing execution and financing.
Market effects
Highlights eVTOL firms shifting toward defense spending, potentially increasing competitive focus on military-grade autonomy and RF/mission systems.
Creates/expands manufacturing, integration, and testing footprint in the Dayton, Ohio region (about 1 million square feet) upon closing.
Defense spending tailwinds tied to conflicts in Ukraine and the Middle East may support broader defense-adjacent aerospace demand.
Counterpoint
The market may discount the acquisition if defense program timelines and contract awards remain uncertain, making the $500M price tag feel like financial risk rather than near-term revenue.
