Shares of automaker Stellantis NV plummeted over 5% in pre-market trading on Tuesday morning. The sharp decline comes amid a combination of analyst concerns over challenges facing the company this year and fears of negative impacts from newly imposed U.S. tariffs on imports from key trade partners.

Citi analysts cut their price target on Stellantis stock to €12 from €13, maintaining a "neutral" rating. They cited expectations of a transitional year for the automaker in 2025 with risks remaining, as earnings are likely to remain weak in the first half ahead of any benefits from new products launching later in the year.

Adding to the stock's woes, U.S. President Trump announced and implemented tariffs of 25% on goods imported from Mexico and Canada, in addition to raising tariffs on Chinese imports by 10%. The move has sparked fears of major supply chain disruptions and retaliatory actions that could hamper U.S. auto exports for integrated automakers like Stellantis that have production spanning North America.
