(No. 25-250), holding 6-3 that the International Emergency Economic Powers Act (IEEPA) does not grant the President authority to impose tariffs.

In recent days, the Trump administration has proposed additional tariffs, causing further uncertainty for many public companies. As companies approach their current quarterly guidance, we took a data-driven approach to see how large public companies provided guidance in light of tariffs and to see if any patterns emerged.

Two courts this week invalidated the tariffs issued by the President under the International Emergency Economic Powers Act (IEEPA). First, late Wednesday night (May 28), the US Court of International Trade (CIT) in V.O.S. v. United States issued an order gutting seventeen executive orders that imposed tariffs under IEEPA.[1]Before the ink could dry on the order, the government appealed and requested a stay from the CIT. Before the CIT ruled on that request, the Court of Appeals for the Federal C
