The analysis highlights Joby's recent test flights in New York and San Francisco, a finalized agreement with Delta Air Lines and Virgin Atlantic for a future UK air taxi service, and its $2.5 billion in cash. However, it notes Joby's higher valuation may lead to greater pressure. Archer, despite a smaller market cap, recently completed a city-to-city flight in California, was chosen as the official air taxi provider for the LA28 Games, and introduced new autonomous aircraft (Thunder and Halo) for defense and commercial applications, supported by $1.8 billion in liquidity. The report concludes Archer's promising opportunities at a more modest valuation make it the preferred investment.
