- Automotive Industry Cost Surge: Automakers such as General Motors and Toyota are facing tariff impacts estimated at up to $9.5 billion, and although the Trump administration has taken steps to alleviate overlapping tariffs, overall costs remain significant, forcing companies to reassess their supply chain strategies.
- Pharmaceutical Sector Stability: Pharmaceutical companies have secured three-year tariff exemptions through pricing agreements with Trump, although new tariffs impose 100% on companies that do not reach agreements, the overall industry is still striving to increase investments in U.S. manufacturing.
