Joby Is Buying a Defense Company. Archer Plans to Buy 3 From Boeing. Here's Which Pivot Makes More Sense.
Joby Aviation (JOBY) plans to acquire Resonant Sciences for $500M, while Archer Aviation (ACHR) will buy three Boeing subsidiaries for a 16.5% stake. Both companies are diversifying into defense to offset delays in commercial eVTOL aircraft. Joby is ahead in FAA certification, but Archer's defense push may be more critical due to its slower progress in consumer eVTOL. Neither company generates significant eVTOL revenue yet.
