Santa Cruz's Joby Aviation Buys Ohio Defense Firm for $500 Million
Joby Aviation will buy Ohio defense tech firm Resonant Sciences for about $500 million, funded with about $450 million cash and $50 million common stock, with closing expected in the first half of 2027, according to Reuters. Resonant’s radio-frequency and mission systems will form Joby’s defense unit. Joby shares fell about 6.5% premarket. Joby also launched a $750 million at-the-market equity program.
How this was made
The 30-second read
Why it matters
The acquisition creates a dedicated defense unit and adds profitable RF and mission systems, but the same-day $750 million at-the-market equity program and the premarket -6.5% reaction point to dilution and financing sensitivity.
Market read
Traders get a same-day catalyst: a large defense-focused M&A deal plus an equity issuance tool, with immediate premarket repricing and a 2027 closing timeline.
What to watch
Closing is targeted for first half of 2027, so interim execution risk remains high; also, commercial FAA certification timing still governs passenger revenue access, limiting how quickly defense profits offset cash burn.
Background
Joby is an electric air taxi developer still pending FAA type certification, while Resonant is a profitable defense technology firm with long-cycle U.S. government and prime-contractor contracts.
Ticker impact
Joby announced a roughly $500 million acquisition of Resonant Sciences and said it will fund it with about $450 million cash and $50 million stock.
Likely continued volatility around deal terms and dilution expectations; directionally supportive on defense diversification, but capped by cash burn and equity issuance.
The article ties the acquisition to immediate defense-market foothold and profit, while also reporting a premarket -6.5% move and a $750 million at-the-market program that can pressure the stock.
Market effects
Highlights eVTOL companies shifting toward defense revenue, potentially increasing competitive focus on RF, autonomy, and mission systems suppliers.
Expands Joby’s Dayton-area manufacturing and integration footprint near Wright-Patterson AFB, reinforcing regional defense aerospace industrial activity.
Ties demand narrative to rising U.S. defense spending amid Ukraine and Middle East conflicts, supporting broader defense-tech capex sentiment.
Counterpoint
The stock drop and large ATM imply the market may view the acquisition as a financing-driven stopgap rather than a durable margin inflection for Joby’s commercial business.
