Joby Aviation has entered into a definitive agreement to acquire Resonant Sciences, a Dayton, Ohio-based defense technology company, for approximately $500 million. The acquisition will represent a significant expansion of Joby’s defense business, delivering immediate scale through a rapidly growing and EBITDA-positive business supporting active U.S. national security programs.
Resonant also brings classified infrastructure, qualified products, established production operations, and longstanding customer relationships, as well as a deeply experienced technical team. By bringing together the companies’ complementary aerospace engineering capabilities, the combination will create a scaled defense growth platform that accelerates autonomy and expands the applications for Joby’s technology.
Joby’s Dedicated Defense Business Unit
Upon closing, Resonant will become Joby’s dedicated defense business and continue to operate under the Resonant Sciences name, led by Co-Founder and CEO J. Micah North. Joby’s existing defense initiatives, built on more than a decade of work with defense and intelligence customers, will be consolidated within the new business unit. These include the development of dual-use turbine-electric and hydrogen-electric aircraft, as well as a dual-use autonomy technology stack.
JoeBen Bevirt, Founder and CEO of Joby Aviation, stated: “Resonant has built an exceptional business that combines advanced technology, vertically integrated production capabilities, and deep customer trust. The combination will pair Resonant’s established capabilities with Joby’s globally leading aircraft propulsion technologies, creating a powerful platform for the next phase of Resonant’s growth. What makes this combination especially compelling is how closely aligned our teams are.”
J. Micah North, Co-Founder and CEO of Resonant Sciences, added: “Demand for advanced defense technology is growing rapidly, and Resonant has built the technology, customer relationships, and manufacturing capabilities required to meet it. Joining Joby gives our team access to additional engineering depth, aircraft platforms, autonomy technology, and production expertise, allowing us to move faster for our existing customers and pursue opportunities that neither company could address alone.”
A High-Growth Defense Business
Founded in 2015, Resonant employs approximately 250 people and designs, manufactures, and delivers advanced RF and mission systems for U.S. national security customers. The company is also a global leader in low-observability technologies, structures, and subsystems, with established capabilities spanning advanced sensing, electronic countermeasures, communications, and autonomous systems. Revenue increased approximately 40 percent year over year to more than $100 million over the last twelve months, with high-teens adjusted EBITDA margins.
Rodrigo Brumana, Chief Financial Officer of Joby Aviation, concluded: “Resonant is a fast-growing business with strong visibility into future revenue, supported by a growing backlog and accelerating demand across its core defense markets. It generates healthy adjusted EBITDA margins, and its technology, customer relationships, and scaled manufacturing make it a strong strategic fit for Joby as we build out our defense business.”
The transaction is expected to close in the first half of 2027, subject to customary closing conditions, including applicable regulatory reviews. Joby expects to fund the transaction with approximately $450 million in cash and $50 million in Joby common stock.
