Bombardier is trading 6.38% down at CA$295.01 after U.S. President Donald Trump threatened on September 7–8, 2026, to ban its aircraft sales in the United States unless manufacturing moves domestically.

  • The U.S. represents more than half of Bombardier’s revenue, and its supply chain already relies heavily on U.S. operations and suppliers.
  • A September 7 agreement with Taiwan’s AIDC to produce Challenger 3500 fuselage components is positive operational news but does not offset the immediate market-access risk.
