How Amgen Makes Money

United States product sales were US$25.66 billion in fiscal 2025, 73% of the US$35.15 billion product sales total and about 70% of total revenues. The largest domestic contributors were Prolia (US$2.98 billion), Enbrel (US$2.20 billion), Otezla (US$1.84 billion), Tepezza (US$1.76 billion), Repatha (US$1.66 billion), Evenity (US$1.60 billion) and Tezspire (US$1.48 billion). Access depends on formulary placement with the large pharmacy benefit managers and on Medicare and Medicaid reimbursement.

Product sales outside the United States were US$9.49 billion in fiscal 2025, 27% of product sales. The largest were Repatha (US$1.35 billion), Aranesp (US$973 million), XGEVA (US$729 million), Vectibix (US$571 million) and Amgevita (US$549 million). Prices are generally lower than in the United States because of government reference pricing and national formulary negotiation.

Biosimilars sit inside product sales and generated about US$3.0 billion in fiscal 2025: Mvasi (bevacizumab) US$771 million, Pavblu (aflibercept) US$700 million, Amjevita and Amgevita (adalimumab) US$597 million, Wezlana and Wezenla (ustekinumab) US$273 million, and US$683 million across the smaller biosimilars reported within other products. Amjevita sales fell 22% year over year, so segment growth now comes from the newer launches.

Also inside product sales, the medicines acquired with Horizon Therapeutics produced about US$4.6 billion in fiscal 2025: Tepezza US$1.90 billion, Krystexxa US$1.34 billion, Uplizna US$655 million and the ultra-rare products US$719 million. Uplizna grew 73% after approvals in IgG4-related disease and generalized myasthenia gravis, while the ultra-rare group fell 5% as Ravicti met generic competition.

Other revenues, mainly royalties, license income and corporate partner payments, were US$1.60 billion in fiscal 2025, the difference between US$36.75 billion of total revenues and US$35.15 billion of product sales. The line carries high margins but is not a growth priority.
