Business

Hioki E.E. Corporation, founded in 1952 and headquartered in Ueda City, Nagano Prefecture, is a specialist manufacturer of electrical measuring instruments. The company operates as the Electrical Measuring Instruments Business (single segment), offering four product categories: Automated Test Equipment, Recording Instruments, Electronic Measuring Instruments, and Field Measuring Instruments. It operates globally through 14 domestic and overseas sales subsidiaries, with its primary customer base centered on decarbonization- and electrification-related industries such as EVs, ESS, data centers, and renewable energy. In FY2025 (ending December 2025), net sales reached ¥40,532 million, with the overseas sales ratio reaching 63.6%, as the company continues to deepen its international expansion, particularly in China and other parts of Asia.

Business Model

The company creates differentiated products through in-house R&D (with an R&D-to-sales ratio of around 10% or more as a benchmark), and sells them via a customer-focused, solution-oriented approach through 14 domestic and overseas sales subsidiaries. It maintains a fundamentally debt-free management policy, funding all capital expenditures and R&D expenses from its own resources. For FY2025 (ending December 2025), the operating margin remained at a high level of 16.8%, supported by the continuous rollout of high value-added products underpinning its earnings base.

Company Strengths

The company continues to invest with a target of maintaining a research and development expense ratio to sales of 10% or more. In FY2025 (ending December 2025), research and development expenses were ¥3,711 million (9.2% of sales), and including R&D-related capital expenditure, this reached ¥5,693 million (14.0% of sales). The company has a track record demonstrating technological superiority, including the development of the ALDAS-E impedance measurement system for hydrogen energy applications and receipt of a Best Paper Award at an IEEE international conference.

The company operates 14 overseas sales subsidiaries across the United States, China, Europe, Southeast Asia, India, the Middle East, Africa, and other regions. In FY2025 (ending December 2025), overseas sales reached ¥25,794 million (63.6% of sales), maintaining a record-high level. In March 2025, the company newly established a subsidiary in Vietnam, further expanding its sales network in Asia. Sales in China recorded substantial growth of 19.0% year on year.

As of the end of FY2025 (ending December 2025), against total assets of ¥51,492 million, net assets stood at ¥43,956 million, with an equity ratio of approximately 85%, maintaining an extremely sound financial structure. The company held cash and cash equivalents of ¥16,723 million and continues to operate debt-free, funding all capital needs internally. Even large-scale investments, including capital expenditure of ¥4,168 million, are financed with the company's own funds.

ENVALITH's Perspective

In H1 FY2026 (ending December 2026), the company achieved substantial revenue and profit growth, with net sales of ¥24,129 million (up 23.5% year on year), operating profit of ¥5,053 million (up 53.5% year on year), and interim net profit of ¥3,990 million (up 73.7% year on year). Progress against the full-year forecast (net sales of ¥47,700 million, operating profit of ¥9,500 million) stood at a solid 50.6% for net sales and 53.2% for operating profit at the halfway point. Given that orders received for Automated Test Equipment surged 127.3% year on year, an acceleration in revenue recognition in the second half is also expected. There is judged to be a reasonable degree of room for the full-year forecast to be revised upward.

The rapid expansion in performance this interim period has been driven primarily by external factors: increased demand for electronic components stemming from expanding data center investment (Electronic Measuring Instruments sales up 34.9% year on year), and a sharp rise in demand for battery testers for ESS applications amid the expansion of renewable energy. Orders from Taiwan stood out with growth of 204.7% year on year, reflecting a concentration of semiconductor- and AI-related investment. Points requiring continued attention going forward include the sustainability of performance once these external tailwinds subside, as well as the risk of rising logistics costs and component costs stemming from escalating tensions in the Middle East.

Sales to China rose 30.1% year on year to ¥6,940 million, accounting for 28.8% of total sales, with dependence on China trending upward. Should geopolitical risk materialize, the impact on performance would be significant. In addition, escalating tensions in the Middle East stemming from the US and Israeli strikes on Iran have led to continued elevated energy prices and rising logistics costs, and the company itself has noted the possibility that rising costs for raw materials and components could affect full-year operating profit. Given that a substantial foreign exchange loss (¥210 million) occurred in the same period of the previous fiscal year, it will also be necessary to continue monitoring how foreign exchange risk is being managed.

Growth Strategy

A three-pronged strategy under Vision 2030 combining high-value-added product launches, overseas expansion, and achievement of carbon neutrality

In the first half of FY2026, the company launched the CT6704 and CT6705 current probes for high-frequency, high-current measurement, the CT6847A clamp sensor for large vehicles, the ST5680A DC withstand voltage insulation resistance tester, and the PW9006 license for power analyzers, among other products. HIOKI continues to bring high-value-added products to market that address increasingly sophisticated measurement challenges in growth areas such as data centers, EVs, ESS, and power semiconductors.

The Nagoya Technical Center began full-scale operations in April 2026, expanding evaluation facilities for the automotive and battery materials fields. In June 2026, an after-sales service center was opened at the Vietnam subsidiary, establishing a local support system in Japanese, English, and Vietnamese. Toward the mid- to long-term target of a 75% overseas sales ratio, the company is advancing the development of repair and calibration hubs and the rollout of on-site services in each region.

The company obtained third-party verification from SGS Japan for greenhouse gas emissions (Scope 1 and 2) and achieved investment-based carbon neutrality. Verification was also carried out for Scope 3 across all categories. Recycled plastic was adopted for the CT6704 and CT6705 current probes. In the 2025 CDP Supplier Engagement Rating, the company received the highest rating of

The company is promoting efficiency measures such as automating the material weighing process, optimizing production flow lines, and reviewing inspection lines and equipment, thereby reducing man-hours, easing worker burden, and stabilizing processes. The operating margin on sales for the first half of FY2026 (ending March 2026) improved significantly to 20.9%, up from 16.9% in the same period of the previous year, contributing to improved profitability together with the effect of absorbing fixed costs through higher sales.
