Boeing has pulled out of a $4.2 billion deal to buy Embraer’s commercial jets division.
The move sparked a furious response from its jilted partner, and also left plans for a U.S.-Brazil alliance in ashes.
The deal fell apart hours after a midnight deadline expired with no agreement on how to implement a deal first aired in 2018.
Boeing accuses Embraer of failing to meet conditions for closing the transaction.
