Amgen Inc. is moving ahead with a $650 million expansion of its biologics facility in Juncos, Puerto Rico, despite experiencing a 4% stock decline this week and holding a 72% strong sell rating from analysts. This initiative aims to create nearly 750 new jobs and reinforces the company's commitment to expanding its U.S. manufacturing capabilities. Notably, Amgen reported robust Q2 2025 results, with revenues up 9% year-over-year and a 92% increase in GAAP earnings per share, which helps sustain a positive outlook among analysts despite ongoing stock valuation concerns.
