Resonant employs ~250 people, over 90% with security clearances, generates $100m+ in annual revenue at high-teen EBITDA margins, and saw first-half bookings triple year-over-year. Post-close, Resonant becomes Joby's dedicated defence unit, absorbing its existing military programmes. The deal reflects Joby's strategy of acquiring profitable operating businesses while awaiting FAA type certification for its eVTOL aircraft — following last year's $125m acquisition of Blade Air Mobility's helicopter business. Investors reacted negatively, with shares falling roughly 4–6.5%. Joby's liquidity will drop from ~$2.3bn to ~$1.85bn after the cash outlay. ## Full article daily.dev links to this article rather than hosting it.
