What ESWIN Computing makes
The prospectus describes ESWIN Computing as a RISC-V-oriented chip product provider. It designs chips, chipsets, circuit boards and supporting software, while outsourcing chip manufacturing, packaging and testing. Its product categories cover human-machine interaction and multimedia processing, as well as interconnectivity and computing. The company also reports IP licensing and technical services in its business activities. These descriptions appear in the company’s prospectus.
As of March 31, 2026, the prospectus counted more than 150 commercialized hardware-software integrated products, more than 620 IP modules and more than 1,740 product-related patent applications.
Customer and supplier concentration
The prospectus reports that ESWIN Computing served 220 customers worldwide during its track-record period. That count describes its reach; the revenue and purchasing shares show how much business was concentrated among a smaller group.
| Reporting period | Largest customer share of revenue | Five largest customers’ share of revenue | Five largest suppliers’ share of purchases |
| 2025 | 64.6% | 89.5% | 54.6% |
| Three months ended March 31, 2026 | 39.3% | 83.1% | 64.4% |
The customer figures measure revenue, while the supplier figures measure purchases. In 2025, one customer accounted for nearly two-thirds of revenue, and the five largest customers together accounted for 89.5%. The supplier figures provide a separate view of the company’s purchasing concentration.
