Roche AG has become the latest pharmaceutical company to respond to the Trump administration’s threat to impose tariffs, saying it will invest $50 billion in drug and diagnostics manufacturing in the U.S. over the next five years. That figure matches a similar commitment by its Basel, Switzerland-based neighbor, Novartis AG, which on April 11 said it would be investing almost $50 billion in the U.S., also over the next five years.
