Financial summary
Amgen
Amgen is a cash-generative business with high product gross margins. In fiscal 2025 it reported US$36.8 billion of total revenues, US$7.7 billion of GAAP net income, a 25.8% GAAP operating margin, US$8.1 billion of free cash flow and US$5.1 billion of dividends paid. Its results used to depend on a few large franchises, first Epogen and Aranesp, then Enbrel. As those matured Amgen bought revenue instead: Onyx in 2013, Otezla in 2019 and Horizon Therapeutics for US$27.8 billion in 2023. That last deal is also the main reason for the balance sheet it now carries, with US$54.6 billion of debt outstanding at December 31, 2025, debt leverage of about 3.2 times EBITDA and US$2.8 billion of net interest expense in fiscal 2025.
AstraZeneca
AstraZeneca's Total Revenue fell from $33.6 billion in 2011 to a trough of $22.1 billion in 2018 as Seroquel, Nexium and Crestor lost exclusivity. Under Pascal Soriot the company redirected spending into oncology and specialty medicines, and revenue then grew every year to $58.7 billion in 2025, with profit for the year of $10.2 billion and gross profit of $48.1 billion on cost of sales of $10.6 billion. R&D investment reached $14.2 billion in 2025, about a quarter of Total Revenue, and the $39 billion Alexion acquisition added a rare disease business the company did not have before 2021.

Where the revenue comes from
Amgen
- U.S. product sales
~70% of total revenues
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.
- International product sales
~26% of total revenues
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
~8% of total revenues
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.
- Rare disease portfolio acquired with Horizon
~13% of total revenues
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
~4% of total revenues
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.
AstraZeneca
- Product Sales~95%
Product Sales were $55,573 million in 2025, up 9%, or about 95% of Total Revenue. This is the direct sale of AstraZeneca-manufactured prescription medicines to wholesalers, pharmacies, hospitals and government buyers. Oncology was the largest therapy area at roughly $25.6 billion of revenue, up 17%, followed by Cardiovascular, Renal and Metabolism, with Respiratory and Immunology and Rare Disease making up most of the balance.
- Alliance Revenue~5%
Alliance Revenue was $3,067 million in 2025, up 39%, or about 5% of Total Revenue. It is mostly AstraZeneca's share of profits on co-commercialised medicines, led by the Enhertu and datopotamab deruxtecan antibody-drug conjugates developed with Daiichi Sankyo, plus Tezspire with Amgen and Lynparza and Koselugo with Merck in certain markets.
- Collaboration Revenue<1%
Collaboration Revenue was $99 million in 2025, down 89% from $923 million in 2024, so less than 1% of Total Revenue. It covers upfront fees, milestone payments and royalties on out-licensed assets, and moves sharply year to year because it depends on when individual deals are signed.
Business model and strategy
Amgen
How it makes money
Amgen operates a high-risk, high-reward biopharmaceutical business model. It spends heavily on research to discover and engineer new biologic drugs: US$7.3 billion in fiscal 2025, or 20.7% of product sales. Once a drug is approved by the FDA, Amgen secures a patent, granting them a temporary monopoly to sell the drug at a premium price.
Growth strategy
Amgen's growth plan has two parts: scale the newer medicines and buy what the pipeline does not supply. Recent launches and acquired products drove the 10% revenue growth in fiscal 2025, with Tezspire up 52% to US$1.48 billion, Repatha up 36% to US$3.02 billion, Evenity up 34% to US$2.10 billion, Uplizna up 73% to US$655 million and Imdelltra reaching US$627 million in its second year.
Competitive advantage
Amgen's main competitive advantage is experience making complex biologics at commercial scale, which it has done continuously since Epogen launched in 1989.
AstraZeneca
How it makes money
AstraZeneca discovers, develops and sells prescription medicines, and the economics turn on patent-protected pricing funded by heavy research spending. It invested $14.2 billion in research and development in 2025, about a quarter of Total Revenue, and reported gross profit of $48.1 billion on cost of sales of $10.6 billion.
Growth strategy
AstraZeneca's growth strategy relies on extending its existing cancer drugs into earlier stages of treatment, before the cancer spreads, which increases the number of patients who can be treated. The $39 billion acquisition of Alexion Pharmaceuticals in 2021 also took it into rare diseases, where drugs treat small patient populations, carry high prices and face little generic competition.
Competitive advantage
AstraZeneca's main advantage is the depth of its oncology portfolio and the Phase III evidence behind it. Tagrisso, Imfinzi, Enhertu, Lynparza and Calquence each rest on trials that changed treatment practice, and the company had more than 100 Phase III studies running at the end of 2025 after 16 positive Phase III readouts during the year.
