Abbott Laboratories has successfully completed its $21 billion acquisition of Exact Sciences, a move aimed at enhancing its presence in personalized precision oncology. However, the company faces over 1,700 lawsuits concerning its Similac infant formula, with claims alleging serious health risks, and has not allocated financial reserves for potential losses. Despite these challenges, Abbott reported strong first quarter sales of $11.16 billion and a growth rate of 13.2% in medical devices, though analysts remain wary, reflected by a Zacks Rank of 4 (Sell) and a declining consensus estimate.
