CoStar, Stride, Vestis, Amentum, and Equifax Shares Plummet, What You Need To Know
A number of stocks fell in the morning session after the Trump administration's announcement of new global tariffs, reignited trade policy uncertainty. The move came swiftly after the Supreme Court ruled the previous week that the president could not use the International Emergency Economic Powers Act (IEEPA) for such duties, a decision that had initially sent markets higher. However, the administration invoked a different authority, the Trade Act of 1974, to impose a 15% global tariff for up to 150 days. The rapid reimposition of trade barriers creates significant uncertainty for companies across multiple sectors that depend on international supply chains and global trade. Investors are now weighing the potential impact of these new duties on corporate earnings and broader economic activity.

Amentum’s Q4 Earnings Call: Our Top 5 Analyst Questions
Amentum’s fourth quarter was marked by a significant revenue decline, missing Wall Street’s expectations due to the impacts of a prolonged U.S. government shutdown and contract transitions. Management acknowledged that these factors, alongside divestitures, led to a challenging revenue environment. CEO John Heller described the quarter as a period where “the longest government shutdown in history impacted performance,” but noted that teams remained focused on delivering for customers. The company’s robust margin performance was attributed to prioritizing higher-margin contracts and disciplined cost control. Despite these operational positives, the market responded negatively to the revenue shortfall and the company’s outlook for modest growth.
