Business

Nippon CMK Corporation is a company listed on the Prime Market of the Tokyo Stock Exchange, primarily engaged in the manufacturing and sale of printed wiring boards. The group, comprising the company along with 11 subsidiaries and 1 affiliated company, operates production and sales facilities across four regions: Japan, China, Southeast Asia (Thailand and Malaysia), and Europe and the United States (Belgium, Germany, and the United States). The domestic Japan segment accounts for approximately 60% of net sales, with major customers including Japanese automotive parts manufacturers such as Denso (net sales of ¥35,155 million for the current period, representing 35.1% of the total). The company has set forth a mid-to-long-term vision of contributing to the realization of a safe and secure automotive society through the development and supply of high-value-added substrates that support ADAS, autonomous driving, and EV adoption.

Business Model

The company has built a role-differentiated global structure centered on the manufacturing of high-value-added products (build-up boards, high heat dissipation substrates, etc.) at domestic factories, complemented by local production in China and Southeast Asia and sales support in Europe and the United States. Based on continuous orders from its major customers, automotive parts manufacturers, it secures earnings by enhancing cost competitiveness through higher value-added products and improved production efficiency. R&D is consolidated in Japan, with R&D expenses for the current period totaling ¥553 million.

Company Strengths

Sales to the major customer Denso reached ¥35,155 million in the current period (¥31,185 million in the previous period), accounting for 35.1% of consolidated net sales. Continued order expansion has been confirmed as a track record, forming a stable customer base that accounts for the majority of the Japan segment's net sales of ¥61,670 million.

Under certification from the Japan Aerospace Exploration Agency (JAXA), the company has established a development and supply system for high-reliability, high environmental-resistance substrates. It is also advancing collaboration with new space-related startups, promoting the sophistication of substrate technology for millimeter-wave radar, ADAS sensors, and control modules for power electronics, and possesses the technical capability to expand into new fields beyond automotive applications.

As a result of the enlargement of production equipment implemented in the previous fiscal year and the integrated management of the two China plants, the China segment profit for the current period reached ¥2,792 million (a 77.3% increase year on year). The promotion of local management led directly to improved profitability through rationalization and reduction of defect rates.

ENVALITH's Perspective

In FY2026 (ending March 2025), construction in progress decreased sharply from ¥33,659 million to ¥12,304 million, while tangible fixed assets (net of buildings and structures) surged from ¥12,832 million to ¥29,846 million, indicating that asset capitalization for the new Thailand plant has moved into full swing. The company itself has explicitly stated that "the depreciation burden from the new Thailand plant is a factor compressing profit," and the FY2027 (ending March 2026) operating profit forecast of ¥3,200 million (up 14.8% year on year) inherently carries the risk of continued losses in the Southeast Asia segment. Early improvement in the utilization rate will be key to earnings recovery.

In FY2026 (ending March 2025), net sales reached a record ¥100,202 million for the first time, while operating profit fell sharply to ¥2,788 million (down 26.8% year on year), with the operating profit margin declining to 2.8% (from 4.0% in the previous period). The cost of sales ratio worsened from 83.6% to 85.1%, and the loss in the Southeast Asia segment (-¥1,476 million) weighed on overall results. The fact that profit attributable to owners of parent secured ¥4,026 million (up 6.2% year on year) depended on an extraordinary gain of ¥1,891 million from the sale of investment securities, making the recovery of core business profitability a key challenge.

Sales dependence on a single customer, Denso, remains high at approximately 35%, and the risk that changes in Denso's procurement policy or fluctuations in automotive demand will directly affect earnings remains significant. As external factors, U.S. tariff policy, energy and raw material supply concerns stemming from conflict in the Middle East, and fluctuations in the yen exchange rate are increasing uncertainty in the business environment. Foreign exchange gains of ¥1,522 million in the current period (compared with ¥1,957 million in the previous period) supported ordinary profit, but there is a structural vulnerability in that ordinary profit could fluctuate significantly depending on changes in the foreign exchange environment. The FY2027 (ending March 2026) earnings forecast assumes an exchange rate of ¥150 to the U.S. dollar, and attention should be paid to downside risk should the yen appreciate further.

Growth Strategy

Achieving mid-term growth through three pillars: full-scale mass production ramp-up at the new Thailand plant, shift toward high-value-added products, and development of new business domains

Construction in progress decreased significantly from ¥33,659 million to ¥12,304 million, reflecting a full-scale shift toward asset capitalization. In the second half of FY2026 (ending March 2026), certain effects of profitability improvement measures were confirmed, but the Southeast Asia segment recorded a full-year loss of ¥1,476 million. In FY2027 (ending March 2026), depreciation burden from the new Thailand plant is expected to be a factor compressing profit, making improvement in capacity utilization and fixed-cost absorption an urgent priority.

In the second half of FY2026 (ending March 2026), an increase in high-value-added products contributed to improved profitability in the Japan segment (segment profit of ¥2,591 million, up 17.1% year on year). The company continues to expand orders for automotive ADAS and driving safety-related products, aiming to reduce the cost-of-sales ratio through improved product mix.

In the Southeast Asia segment, sales of Printed Wiring Boards for Home Appliances performed well (net sales of ¥17,396 million, up 11.6% year on year). The company has explicitly stated its intention to "promote sales expansion into new business areas beyond automotive," positioning the reduction of dependence on the automotive market and diversification of revenue sources as a mid-term challenge.

The larger panel sizes for production equipment and the management integration of the two China plants implemented in the previous fiscal year bore fruit in the current fiscal year, achieving segment profit of ¥2,792 million (up 77.3% year on year). This substantial profit increase, achieved despite headwinds from declining sales to Europe due to reduced EV demand, reflects the results of structural reform, and productivity improvement and cost reduction will continue to be promoted.
