China is the largest, with $1.5 billion of revenue (55% of the total), followed by Taiwan at $550 million (20%). 3% of revenue came from the United States. ## How Does Monolithic Power Systems Make Money? No single region supplies a majority of revenue: the largest, China, is 55%, which spreads Monolithic Power Systems's exposure across several demand drivers. Between fiscal 2024 and 2025, South East Asia grew fastest (+88.1%) and Taiwan slowest (-4.8%), so the revenue mix tilts toward South East Asia while that gap lasts. | Region | FY2025 revenue | FY2024 revenue | Share of revenue | Change | | --- | --- | --- | --- | --- | | China | $1.5 billion | $1.2 billion | 55.3% | 31.1% | | Taiwan | $550 million | $578 million | 19.7% | -4.8% | | South Korea | $253 million | $168 million | 9.1% | 50.5% | | South East Asia | $148 million | $79 million | 5.3% | 88.1% | | Europe | $114 million | $87 million | 4.1% | 30.6% | | United States | $97 million | $55 million | 3.5% | 75.1% | | Japan | $84 million | $62 million | 3.0% | 36.9% | | Other Region | $484,000 | $310,000 | 0.0% | 56.1% | ![Bar chart of Monolithic Power Systems revenue by region for fiscal 2025: China 55.3%, Taiwan 19.7%, South Korea 9.1%, South East Asia 5.3%, Europe 4.1%, United States 3.5%, Japan 3.0%, Other Region 0.0%.](https://www.getswoopr.com/images/charts/monolithic-power-systems-business-model-segment-mix.webp) *Monolithic Power Systems revenue by region as a share of total revenue, from the table above.

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 Monolithic Power Systems reported in the segment note and revenue disclosures of its Form 10-K filed February 27, 2026 (accession 0001437749-26-006113), 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. ## Frequently Asked Questions ### What are Monolithic Power Systems's main regions?
