Archer Aviation filed a countersuit against Joby Aviation accusing it of fraudulent conduct by misrepresenting the origin of certain aircraft materials to evade U.S. import tariffs. The lawsuit alleges Joby concealed supply chain links to China, potentially avoiding regulatory scrutiny and import duties, intensifying a prior trade-secret dispute between the two companies.

Archer was chosen as one of eight participants in the FAA eVTOL Integration Pilot Program to test air taxi operations and shape future National Airspace standards. The selection spurred a roughly 3% gain in Archer's share price, reflecting investor optimism about its role in next-generation air mobility initiatives.
