The stable rating outlook on AbbVie Inc. reflects S&P Global Ratings' expectation that AbbVie's revenue will grow at a low- to mid-single-digit rate, supported by relative stability of worldwide sales of immunology drug, Humira, as well as continued growth in the rest of AbbVie's portfolio. We also expect the company's EBITDA margin will remain stable and cash flow generation will remain strong. We expect this will enable AbbVie's leverage to remain between 2x and 3x. We could lower the rating if the company sustained leverage above 3x. This could happen if the company completed another non-accretive debt-funded acquisition or share repurchases approaching $12 billion. In our opinion, a slowdown of growth is unlikely to precipitate a downgrade on its own,
