Amgen is a mature-stage biotechnology company: a few large medicines, patent cliffs, and acquisitions to replace them.
The portfolio spans inflammation, oncology, cardiovascular and bone medicines. Several key products have passed or are passing patent expiry, and their revenue declines under biosimilar pressure — while the company itself also markets biosimilars of others' drugs, working both sides of that process.
The replacement strategy is acquisition: buying Horizon Therapeutics added rare-disease medicines, where competition is lower and treatment prices higher. A separate bet is obesity, where the company is developing a medicine with a different delivery mechanism from the market leaders'.
Those deals were debt-financed, so leverage runs above the sector average and the cost of money matters more. Amgen pays a high dividend and raises it, which defines its investor base.
