Direct Answer
Gilead Sciences reports revenue across 3 geographic regions in its fiscal 2025 Form 10-K. United States is the largest, with $20.9 billion of revenue (71% of the total), followed by Europe at $5.1 billion (17%). 71% of revenue came from the United States.
How Does Gilead Sciences Make Money?
United States supplies 71% of revenue, so Gilead Sciences's results move mostly with that one region; the others matter more for diversification than for the headline number. Between fiscal 2024 and 2025, Europe grew fastest (+9.3%) and Rest of World slowest (-0.7%), so the revenue mix tilts toward Europe while that gap lasts.
| Region | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| United States | $20.9 billion | $20.6 billion | 70.9% | 1.4% |
| Europe | $5.1 billion | $4.6 billion | 17.2% | 9.3% |
| Rest of World | $3.5 billion | $3.5 billion | 11.9% | -0.7% |
What the Segment Figures Do Not Show
The rows above add up to 100% of Gilead Sciences's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.
Where These Numbers Come From
Every figure on this page is a value Gilead Sciences reported in the segment note and revenue disclosures of its Form 10-K filed February 24, 2026 (accession 0000882095-26-000006), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.
Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
