Yes—in important contract-manufacturing categories, but the strongest recent quantified evidence is specific to notebook PCs, not the entire electronics manufacturing services (EMS) market. Pegatron’s 2025 annual report records an estimate that Taiwan-headquartered notebook ODM/EMS companies shipped 131 million units, about 71% of global notebook volume. That supports a strong position in notebooks; it does not establish Taiwan-wide dominance across all electronics manufacturing or settle how Taiwanese providers compare with mainland Chinese EMS firms today.
What the latest notebook figures show
Pegatron’s 2025 annual report, published in 2026, cites market research estimating that Taiwan notebook PC ODM/EMS companies shipped 131 million units in 2025—about 71% of global notebook shipments. These are reported estimates for one product category, not an independently measured share of all EMS revenue or production.
| Company | Notebook units in 2025 |
|---|---|
| Quanta | 46.73 million |
| Compal | 25.84 million |
| Wistron | 21.72 million |
| Inventec | 13.5 million |
| Pegatron | 9.1 million |
The company figures are listed in Pegatron’s report; the table identifies major Taiwan providers but does not account for every maker included in the estimated 131 million total. ODM (original design manufacturing) generally involves design work alongside manufacturing, while EMS refers to electronics manufacturing services. Different studies may define the services and market boundaries differently, so figures should not be compared without checking their scope.
Why the Foxconn figure is not a Taiwan-wide market share
Hon Hai Technology Group (Foxconn) says its own EMS market share exceeds 40%, across smart consumer electronics, cloud and networking, computing, and components and other. This is a company-reported claim about Foxconn, not an independent estimate of Taiwan’s national share. It covers a different scope from the notebook shipment estimate and should not be combined with it. Foxconn also reported 2025 revenue of TWD 8.1 trillion on its official company news page; revenue is a measure of company scale, not proof of market share.

What China’s competition evidence does—and does not—establish
The U.S.-China Economic and Security Review Commission’s 2025 Annual Report to Congress describes Chinese semiconductor-capacity expansion and price pressure affecting non-Chinese chip companies. That is relevant context for Taiwan’s broader electronics ecosystem, but it concerns semiconductor competition, not a direct comparison of Taiwanese and Chinese EMS providers. It does not show that mainland Chinese contract manufacturers have displaced Taiwan’s firms.
The U.S. Department of Commerce’s 2022 assessment of critical ICT supply chains includes historical EMS/ODM market-share context. It can inform how the industry looked at that time, but it is too old to serve as a current ranking. The available figures here do not provide a like-for-like, current comparison of Taiwan-headquartered and mainland Chinese providers by product category, services, or revenue.
How to read claims of “dominance”
A market-share claim is meaningful only when its boundaries match the question being asked. Before comparing providers or countries, check:
- Product: notebook PCs, smartphones, servers, or another category.
- Services: assembly alone, or a broader package that includes design, sourcing, testing, and logistics.
- Measure: units shipped, revenue, or share of a defined market.
- Geography: where a company is headquartered versus where its factories operate.
- Time and source: a 2025 reported estimate is not equivalent to a company claim or a 2022 government assessment.
These distinctions matter because a Taiwan-headquartered company can operate globally. Foxconn says it operates in 24 countries, but that footprint alone does not reveal how much production takes place in China or elsewhere.
Why the position matters to the industry
Pegatron’s report describes continued outsourcing and demand for more integrated design, assembly, and testing. It identifies consumer electronics, automotive, and medical applications as potential growth areas and highlights AI, electric vehicles, 5G, and medical electronics. These are the company’s account and outlook, not independently verified market forecasts.
The same report says component shortages and rising prices create uncertainty for 2026 PC shipments, while projecting continued global server-shipment growth, including demand associated with AI inference. Those are forward-looking expectations, not confirmed 2026 results. Pegatron also says geopolitical and supply-chain risks are making regionalized and multisite production more important; its report does not quantify a resulting shift in production locations.
Rank #4
What can be concluded
Taiwan retains substantial scale in notebook ODM/EMS, with Pegatron’s report citing an estimated 71% of global notebook volume in 2025. Foxconn separately reports a large EMS share for its own group. Neither figure answers the broader question of Taiwan’s total share across EMS categories, and the semiconductor competition evidence does not settle the direct contest with Chinese EMS providers. A current comparison would need consistent market definitions, product-level data, and a clear distinction between company headquarters and factory locations.
