Amgen, which has gained Horizon's two key products Tepezza and Krystexxa, said it will provide an updated annual forecast during its third-quarter earnings call.
RBC Capital Markets analyst Gregory Renza expects Amgen's updated forecast to weave in revenue from Horizon's drugs, which could partially offset the company's "maturing product line".
Tepezza could be a "core driver" for Amgen, Renza said, adding that the drug can bring in $3.9 billion in peak sales.
