...AbbVie is a leading global branded biopharmaceutical company with good positions in several therapeutic areas. AbbVie benefits from the same high barriers to entry, good pricing power, strong profitability, and limited sensitivity to the business cycle as other rated Big Pharma peers. The company's scale (2022 revenue of about $58 billion), profitability (adjusted EBITDA margins of 53%), product diversity (top product expected to represent less than 25% of revenues over the next few years, an improvement from prior levels), and therapeutic diversity (top therapeutic area is expected to be in the 43%-50% range) are in line with or better than most peers'.
