Abbott Laboratories

COVID-19 testing continued to drive revenue growth for Abbott Labs in 2021: As of January 2022, the company had distributed about 1.4 billion tests, and those generated $7.7 billion in sales in 2021. Medical devices and nutrition products like Similac and Ensure together account for about two-thirds of Abbott’s revenue. The nutrition division endured a setback in early 2022, however, when Abbott issued a voluntary recall of powdered infant formula manufactured in one of its facilities in Michigan after the plant was linked to a bacterial-infection outbreak; the shutdown contributed to a nationwide formula shortage.
