The United States Court of Appeals for the Fourth Circuit ruled on July 21, 2026, to revoke the certification of a shareholder class action against Boeing. The lawsuit stemmed from the January 2024 incident where a cabin door detached from an Alaska Airlines Boeing 737 MAX 9 aircraft. Shareholders accused Boeing of issuing misleading statements and falsely claiming safety commitments to inflate stock prices following the 2018-2019 crashes. The district court had previously allowed a class action for shareholders who purchased shares between January 7, 2021, and January 8, 2024. However, the appeals court ruled that shareholders failed to provide an appropriate method for calculating collective damages, overturning the original decision. Boeing expressed satisfaction with the ruling, though the underlying securities fraud allegations were not dismissed. The case will be remanded to the district court for further proceedings, allowing plaintiffs to revise their damages model or explore other legal avenues.
