Business Details

Enplas's core segment, manufacturing and selling various IC Test Sockets and Burn-in Sockets. It has a global structure combining domestic manufacturing and sales (Enplas Semiconductor Devices Corp., QMS Co., Ltd.) with overseas manufacturing and sales (Singapore, Vietnam sites, etc.). The segment targets server, automotive, and mobile applications as its main focus, with emphasis on sockets for AI servers and products for major GPU manufacturers. Leveraging precision processing technology for engineering plastics as its core strength, it provides solutions to customer challenges in the testing process.

Recent Overview

Sharp increase in AI, server, automotive, and mobile demand led to rapid growth in both net sales and profit

In FY2026 (ending March 2026) full year, demand for server, automotive, and mobile applications increased significantly, resulting in rapid expansion with net sales of ¥23,603 million (up 46.4% year on year) and segment operating profit of ¥4,974 million (up 225.2% year on year). For sockets for AI servers, in addition to major GPU manufacturers, demand related to ASICs for hyperscalers is expected to increase, and the company continues to focus on solution development to strengthen competitiveness as well as technology development and business expansion.

Key Products

product
IC Test Sockets

Sockets for the testing process that inspects the electrical characteristics of various ICs. Deployed for server applications (for AI GPUs and ASICs), automotive applications, and mobile applications. Demand related to ASICs for hyperscalers is expected to increase.

product
Burn-in Sockets

Sockets used for semiconductor reliability testing under high-temperature, high-voltage environments. Demand for server and automotive applications increased significantly. This upward trend is expected to continue over the medium term.

Growth Drivers

  • Expansion of demand for sockets for AI servers (in addition to major GPU manufacturers, ASIC-related demand from hyperscalers is expected to increase)
  • Medium-term increase in demand for test sockets driven by progress in automotive electrification
  • Expansion of demand for mobile applications
  • Aggressive promotion of solution development to strengthen competitiveness
  • Focus on technology development and business expansion for test sockets aimed at future growth

Risks

  • Risk of prolonged adjustment in semiconductor demand
  • Risk of demand fluctuation due to the impact of US trade policy
  • Risk of market contraction due to stagnation in the Chinese economy
  • Demand fluctuations due to timing gaps in customers' transition to next-generation products
  • Risk of rising energy prices and raw material costs due to escalating tensions in the Middle East
  • Foreign exchange fluctuation risk
