Why is Bombardier stock dropping today?

Bombardier's stock took a significant plunge of 6.7% to CA$294.03 following U.S. President Donald Trump's demand on Truth Social for the Canadian private jet manufacturer to stop selling aircraft in the American market unless it shifts manufacturing to U.S. soil. The United States represents over half of Bombardier's revenue, with analysts forecasting a full-year 2026 revenue of around US$10.2 billion.

A ban on selling in the U.S. market could lead to a loss of approximately US$5 billion in annual top-line revenue. Bombardier responded by emphasizing its strong presence in the U.S. with around 3,500 employees, 2,800 U.S.-based suppliers, and over US$2.5 billion in annual supplier spending. However, investors did not seem convinced that the threat could be easily overcome, leading to heavy selling throughout the session.

No specific analyst upgrades or downgrades were noted after the move. The situation was further complicated by Canada's retaliatory tariffs, which take effect on Tuesday and cover up to CA$27.6 billion worth of U.S. imports at rates up to 50%. This escalated trade war alongside a risk-off sentiment in North American equities created a perfect storm of negative factors that pushed Bombardier's stock to its session low of CA$290, a drop from its 52-week high of CA$377.77.
