Eli Lilly, the maker of blockbuster weight loss and diabetes drugs Zepbound and Mounjaro, said it will invest an additional $27 billion to build four new manufacturing plants in the United States, shoring up domestic manufacturing as President Donald Trump threatens new tariffs on pharmaceuticals.

It comes as companies work to build goodwill with Trump, who has emphasized reshoring manufacturing to the U.S. and reducing reliance on foreign supply chains.

Drugmaker Eli Lilly plans to build four new manufacturing plants in the U.S., a $27 billion investment that the company expects will create 3,000 high-skilled jobs and employ 10,000 construction workers.
