Joby Aviation Acquires Resonant Sciences for $500 Million to Scale Defense Unit
The eVTOL pioneer absorbs the Ohio-based sensor specialist to diversify revenue and isolate its commercial air-taxi certification efforts.
Joby Aviation has entered into a definitive agreement to acquire Resonant Sciences, a defense technology firm, for approximately $500 million in cash and stock. The move establishes a dedicated defense business unit, allowing Joby to scale its military capabilities while insulating its primary commercial goals from operational distractions.
Based in Dayton, Ohio, Resonant Sciences specializes in sensor systems and radio frequency (RF) technology. The company reported $100 million in trailing 12-month revenue. As part of the deal, Resonant Sciences' co-founder and CEO, J. Micah North, will lead Joby's newly formed defense division, which will absorb the acquired company's existing autonomy technology and government projects.
Strategic Diversification
Joby is primarily recognized for its development of electric vertical takeoff and landing (eVTOL) air taxis. However, the path to commercial certification is notoriously expensive and time-consuming. To mitigate these financial pressures, Joby has adopted a strategy of acquiring established, revenue-generating businesses. This latest deal follows a similar pattern to last year's $125 million acquisition of Blade Air Mobility's helicopter rideshare business.
Joby is not new to the defense sector. The company has previously collaborated with L3Harris Technologies on hybrid VTOL aircraft and successfully demonstrated a hydrogen-electric hybrid version of its S4 aircraft in 2024. By integrating a specialized firm like Resonant Sciences, Joby moves beyond experimental collaborations toward a structured corporate entity capable of managing classified government programs.
Industry Implications
This acquisition transforms Joby's defense efforts from a series of disparate projects into a standalone, revenue-generating business unit. By securing Resonant Sciences' RF and sensing expertise, Joby accelerates its ability to deploy autonomous, hybrid-electric aircraft for military applications. This creates a critical secondary income stream that can subsidize the high burn rate associated with the commercial aviation sector.
Furthermore, the structural split ensures that the core engineering team remains focused exclusively on the certification and launch of the commercial electric air taxi. By delegating defense operations to a dedicated unit led by North, Joby reduces the risk of mission creep and ensures that the rigorous requirements of FAA certification are not compromised by the differing demands of military contracts.
Future Outlook
Market reaction to the deal has been mixed, with some reports indicating a dip in Joby's stock price following the announcement. Investors are likely weighing the immediate $500 million expenditure against the long-term benefits of diversified revenue.
Observers will now watch how quickly Joby can integrate Resonant Sciences' sensor technology into its existing S4 platform. The primary question remains whether this defense-first revenue model will provide enough of a cushion to carry the company through the final, most expensive stages of its commercial air-taxi rollout.
