AbbVie Inc. has announced a $380 million investment to expand its U.S. manufacturing capabilities with the construction of two new active pharmaceutical ingredient facilities in North Chicago. This strategic move comes despite a recent downgrade from RBC Capital Markets, shifting its rating from 'Strong' to 'Neutral.' Additionally, AbbVie received FDA approval for a new leukemia treatment, bolstering its oncology portfolio as it pursues a $20 billion acquisition of Revolution Medicines. Despite a 13.6% rise over the past year, concerns linger over stock performance fluctuations and an impending EPS forecast of $3.01.
