Analysis
Boeing agreed to sell three subsidiaries -- Wisk Aero, Insitu and SkyGrid -- to Archer Aviation in an all-stock transaction, receiving newly issued Archer shares equal to 19.75% of Archer's shares outstanding immediately before closing, which works out to roughly a 16.5% stake in the combined company after the deal, plus options to buy more shares over the next four years, according to Boeing's investor relations page and TechCrunch. Archer stock jumped as much as 18% in pre-market trading on the news, while Boeing shares were roughly flat.
Wisk Aero, an autonomous eVTOL developer, was previously majority-owned by Boeing and had actually sued Archer for trade-secret theft in 2021 -- the two companies settled that lawsuit and struck a partnership in 2023. The new deal, announced exactly three years to the day after that settlement, according to The Air Current, turns former legal adversaries into one combined company. Insitu makes small unmanned aircraft systems, and SkyGrid builds digital airspace and air-traffic-management software -- both give Archer capabilities well beyond passenger eVTOL, into defense-relevant drone hardware and the software layer that manages autonomous airspace.
Boeing frames the deal as building "an end-to-end physical AI platform for aerospace and defense," combining decades of autonomy, eVTOL and unmanned-systems work developed separately across Wisk, Insitu and SkyGrid, per Archer's own investor release. For Boeing, the deal is a way to exit three subsidiaries it's struggled to commercialize independently while retaining meaningful upside through equity rather than a straight divestiture -- a structure similar to how Boeing has offloaded other non-core units this cycle.
The risk sits with integration, not strategy. Archer is folding three separate businesses -- passenger eVTOL, small drone hardware, and airspace-management software -- into one company at a moment when none of the three has reached large-scale commercial revenue on its own. Boeing's ~16.5% stake also means its own balance-sheet troubles and strategic priorities now have an outsized say in Archer's cap table, a dependency that cuts both ways if Boeing needs liquidity later.
