Business
TESEC Corporation, founded in 1969, is a semiconductor testing equipment specialist that develops, manufactures, and sells Testers, which evaluate the electrical characteristics of semiconductors, and Handlers, which automatically transport and sort devices, as its core products. Based at its domestic headquarters (Higashiyamato City, Tokyo) and Ina Office in Nagano Prefecture, the company conducts global sales and after-sales service through four consolidated subsidiaries in the United States, Malaysia, and China. Its main customers are manufacturers of analog ICs, power semiconductors, and AI-related semiconductors, with overseas sales accounting for approximately 90% of Handler shipments. The company is listed on the Standard Market of the Tokyo Stock Exchange.
Business Model
The company's primary revenue source is the sale of Handlers and Testers, with Handlers—characterized by higher unit prices and larger order lots—serving as the main driver of earnings fluctuations. In addition, the company has a structure in which "Parts, etc." such as Change Kits, based on the number of Handlers in operation, accumulate as stock-type recurring revenue. Working capital and capital expenditures are generally funded through internal resources, maintaining a debt-free management approach. The company has adopted a dividend policy targeting a DOE of 4%, with a stated policy of balancing growth investment with shareholder returns.
Company Strengths
Starting with the development of transistor handlers and testers, the company has a track record of continuous new product development, including MAP Handlers (1999), high/low temperature handlers for power devices (2010), and the DC/UIS one-pass test system (2023). In February 2026, it launched the Lead Frame Strip Test Handler (Tri-Temp) to the market, expanding its product lineup.
The company has consolidated subsidiaries in the US, Malaysia, and China, and has a high degree of overseas dependence, with approximately 90% of handler shipments destined for overseas markets. In the fiscal year ended March 2026, INFINEON TECHNOLOGIES (Malaysia) emerged as a major customer, accounting for 10.7% of net sales (¥596 million), reflecting the company's global customer base.
As of the end of FY2026 (ending March 2026), total assets stood at ¥15,896 million against net assets of ¥14,200 million (net asset ratio of approximately 89%), with zero outstanding borrowings. The company holds a ¥1 billion commitment line contract that remains unused, maintaining financial stability even amid a cyclical market environment. Operating cash flow also remained positive at ¥1,464 million in FY2026 (ending March 2026).
ENVALITH's Perspective
Performance Trend
Revenue peaked at ¥8,743 million in FY2023 (ending March 2023) and declined for two consecutive periods, falling to ¥5,567 million in FY2026 (ending March 2026), a 36% decrease from the peak. Operating profit also fell sharply from ¥2,133 million in FY2023 (ending March 2023) to ¥301 million in FY2026 (ending March 2026), with the operating margin contracting from 24.4% to 5.4%. As an external factor, restrained investment in power semiconductors due to slowing EV demand directly impacted the Testers segment, and while expanding AI-related demand drove a recovery in Handlers, the decline in capacity utilization stemming from the Testers slump and the burden of fixed costs pushed down profit levels. Order intake turned upward in FY2026 (ending March 2026), increasing 35.1% year on year for the first rise in four periods, suggesting that performance has bottomed out.
Growth Strategy
Under the medium-term plan 'Enjoy2.1', the company aims to capture AI and power semiconductor demand, targeting net sales of ¥9,000 million in FY2028 (ending March 2028)
Developing an expanded-application version of MAP Handlers for AI servers. This will enable support for shapes and sizes that were previously difficult to accommodate, strengthening market competitiveness. In parallel with maintaining stable transactions with existing customers, the company will develop new markets, targeting Handler sales of ¥4,100 million in FY2028 (ending March 2028).
Progressing development of a renewed model of the switching tester and expanding the functionality of the wafer parallel tester. With an eye toward the recovery of the EV market, the company will maintain and strengthen the competitiveness of products for next-generation power semiconductors including SiC, targeting Tester sales of ¥3,500 million in FY2028 (ending March 2028).
To respond to expanding demand accompanying the recovery in orders, the company is promoting the standardization and efficiency improvement of production processes to enhance supply stability, along with enhancing the materials procurement system. Securing supply capacity capable of responding to an increase in large-scale projects and short-lead-time orders is positioned as a key priority.
The company has restructured its dividend policy with a target DOE of 4%, implemented share buybacks, introduced a J-ESOP, and raised the incentive rate for the employee stock ownership plan. It will strengthen dialogue with medium- to long-term investors through the introduction of a rolling plan and enhanced IR activities.
The company is promoting digitalization through the development of its next-generation core system (with an investment of ¥112 million in software in process), and is advancing the development of globally capable talent and the restructuring of its organizational structure as a foundational strategy.
