General Motors (GM) has withdrawn its earnings guidance for 2025 and temporarily suspended its $4 billion share buyback program, pending a comprehensive evaluation of the impact of US tariffs. Despite surpassing first-quarter earnings expectations, the lingering uncertainty regarding tariffs has compelled the company to take this prudent decision. GM emphasized that withdrawing earnings guidance and suspending share buybacks was a necessary step in light of the unclear ramifications of the US tariffs. This action highlights the significant influence of Trump-era trade policies on the business strategies of American corporations. With the added pressure of import tariffs and the threat of retaliatory actions from trading partners, a growing number of American companies are opting to withdraw their earnings forecasts.
