The 25% tariffs on Canadian and Mexican goods that U.S. President Donald Trump last week was set to impose have clouded the outlook for companies such as Bombardier (BBD.B:CA). The countries agreed to delay tariff actions for 30 days as they negotiate issues including border security.

Bombardier on Thursday reported a fourth-quarter decline in profit and slower-than-expected revenue growth and said it won't provide guidance for 2025 due to the uncertainty posed by the threat of U.S. import tariffs on Canadian goods.

Bombardier separately announced strong results for the fourth quarter, with full-year revenues rising 8 per cent to $8.7bn, driven by a record performance in its services business, and 146 aircraft deliveries. Adjusted earnings before tax were up 11 per cent year-on-year to $1.36bn.

The tariffs would pose big problems for Bombardier, which counts more than 2,800 suppliers across 47 states in the U.S.
