Joby Aviation Doubles Down on Defense With $500M Resonant Sciences Deal
Electric vertical take-off and landing (eVTOL) pioneer Joby Aviation (NYSE: JOBY) announced Tuesday it will acquire Dayton, Ohio-based defense technology firm Resonant Sciences for approximately $500 million. The move signals a strategic diversification as the company navigates longer-than-expected commercial certification timelines while defense budgets surge globally.
The all-cash-and-stock transaction—comprising $450 million in cash and $50 million in Joby common stock—is expected to close in the first half of 2027. Upon completion, Resonant Sciences will become Joby’s dedicated defense business unit, housing its hybrid-electric and autonomous VTOL programs, while Joby’s core commercial air taxi initiative continues independently.
Why Defense? Why Now?
The eVTOL sector has faced persistent headwinds: complex FAA certification processes, infrastructure gaps, and profitability questions have pushed commercial launch targets years into the future. Meanwhile, defense spending has accelerated sharply due to conflicts in Ukraine and the Middle East, creating a lucrative, near-term revenue stream for dual-use aviation technologies.
Resonant Sciences specializes in advanced radio-frequency (RF) and mission systems that “help aircraft see, communicate, and operate in complex environments,” according to Joby CEO JoeBen Bevirt. These capabilities—electronic warfare, secure communications, and spectrum dominance—are critical for modern military operations and align with the Pentagon’s push for autonomous, networked air platforms.
Market Reaction and Financial Implications
Shares of Joby fell 6.5% in premarket trading following the announcement, reflecting investor skepticism about capital allocation away from the core air taxi mission. However, the deal provides immediate access to ~1 million square feet of manufacturing, integration, and test space across the Dayton region—a strategic asset for scaling both defense and commercial production.
Analysts note the acquisition could accelerate Joby’s path to profitability by tapping into defense procurement cycles that are faster and better funded than commercial certification. The combined entity gains a foothold in the growing military unmanned aerial systems (UAS) market, projected to exceed $30 billion annually by 2030.
Broader Industry Context
Joby is not alone in pursuing defense contracts. Competitors like Archer Aviation, Beta Technologies, and Lilium have all secured military partnerships or grants. The trend reflects a classic dual-use innovation model: defense funding de-risks technology development, which later trickles down to commercial applications—much like GPS, the internet, and jet engines.
For Joby, the Resonant Sciences acquisition also brings an established customer base within the U.S. national security apparatus, potentially stabilizing revenue while the air taxi market matures.
FAQ: Joby Aviation’s Defense Pivot
1. Does this acquisition delay Joby’s commercial air taxi launch?
Management insists the commercial eVTOL program remains the priority and will stay “laser focused” on certification and service entry. The defense unit operates separately, potentially reducing resource competition. However, investors will monitor whether engineering talent and capital get diverted.
2. What specific capabilities does Resonant Sciences add?
Resonant provides RF sensing, electronic warfare, and secure communication systems designed for contested environments. These technologies enhance survivability and situational awareness for both manned and unmanned aircraft—key requirements for military VTOL operations.
3. How is the deal funded, and what’s the impact on Joby’s balance sheet?
The $500 million purchase price is funded with $450 million cash and $50 million stock. Joby held over $1 billion in cash and equivalents as of its last quarterly report, so the cash portion is manageable. The stock component minimizes dilution while aligning incentives.
