AbbVie Inc. experienced a significant stock decline of over 8% after announcing its first-quarter earnings, which included a revenue of $13.54 billion, falling short of expectations. Despite reporting earnings per share of $3.16, the company lowered its annual adjusted EPS guidance and missed key top-line estimates, raising concerns about growing competition for its blockbuster drug Humira. Analysts suggest there may be a buying opportunity in the dip, yet uncertainty about AbbVie's reliance on Humira amid upcoming patent expirations looms.
