Archer Aviation Surges 20% After Agreeing to Acquire Boeing's Wisk Aero, SkyGrid and Insitu in All-Stock Deal

Archer Aviation shares jumped roughly 20% to $6.63 on Monday after the California eVTOL startup signed definitive agreements to acquire three Boeing subsidiaries, Wisk Aero, SkyGrid and Insitu, in an all-stock transaction. Boeing will receive a stake in Archer reported variously as 16.5% by the New York Times and 19.75% by other outlets, along with warrants and the right to nominate a director to Archer's board. Wisk Aero develops autonomous eVTOL aircraft, SkyGrid provides air-traffic management software for urban air mobility, and Insitu manufactures high-altitude drones with military applications and generates more than $200 million in annual revenue.

Boeing retains access to Wisk's autonomous flight technology under a long-term collaboration agreement. The transaction is expected to close by year-end 2026 and represents part of Boeing CEO Kelly Ortberg's broader divestiture program. Separately, Archer reported second-quarter earnings after the close, posting revenue of $5.0 million against analyst estimates of $2 million, with GAAP EPS of negative $0.34 in line with expectations, a net loss of $263.2 million and adjusted EBITDA of negative $177.1 million.

The company guided third-quarter adjusted EBITDA to a range of negative $170 million to negative $200 million. Rivals Joby Aviation and EHang did not participate in Monday's rally.
