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.
SpaceX
SpaceX revenue grew from $10.387 billion in 2023 to $14.015 billion in 2024 and $18.674 billion in 2025, but heavy Starship, Starlink, and AI spending produced a $4.937 billion FY2025 net loss. In Q2 2026, its first quarter reported as a public company, revenue was $7.8 billion (up 92%), adjusted EBITDA was $3.5 billion, net loss was $541 million, and backlog was $47.5 billion. The IPO raised $85.7 billion and a $25 billion bond sale added more liquidity. In late September 2026 the stock traded near $145, for a market capitalization around $1.9 trillion.

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.
SpaceX
- Launch services
Not formally reported
Commercial, civil, and national-security launches priced by rocket, payload, orbit, and service type.
- Starlink consumer broadband
Not formally reported
Monthly subscriptions and terminals for residential and mobile broadband.
- Enterprise and government connectivity
Not formally reported
Starlink enterprise, aviation, maritime, backup connectivity, Starshield, and government services.
- AI infrastructure
Not formally reported
Compute and cloud services from SpaceX's AI segment, formed through the xAI combination; $2.6B revenue in Q2 2026.
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.
SpaceX
How it makes money
SpaceX earns money in three segments. Space sells launches on Falcon 9 and Falcon Heavy, plus Dragon cargo and crew missions for NASA, the U.S. government, and commercial customers ($962 million in Q2 2026).
Growth strategy
SpaceX's growth plan has four parts: add Starlink subscribers and raise enterprise, aviation, and mobile revenue; launch higher-capacity Starlink V3 satellites on Starship; expand national-security work through Starshield and launch contracts (over $6 billion in U.S. government awards in Q2 2026); and scale AI compute capacity, which grew from 400 megawatts a year earlier to 1.4 gigawatts at the end of Q2 2026.
Competitive advantage
SpaceX's advantage is reusability combined with vertical integration. It builds its own engines, avionics, rockets, and satellites, and reflies Falcon 9 boosters many times, which lowers its marginal launch cost below rivals that still expend most hardware. Being its own largest launch customer lets it deploy Starlink at a cadence no other operator has matched, and Starlink revenue then funds Starship.
