Business

Niterra (formerly NGK Spark Plug), founded in 1936, is a ceramics technology-based manufacturer and global group comprising 62 subsidiaries and 14 affiliates. Its core Automotive-related business supplies spark plugs, glow plugs, and various sensors to automakers worldwide and the aftermarket, accounting for approximately 80% of revenue. The Components & Solutions business handles Cutting Tools, ceramic components for semiconductor production equipment, IC packages, and Medical Oxygen Concentrators, targeting growth in the semiconductor market driven by expanding demand for generative AI. Consolidated revenue for FY2026 (ending March 2026) reached ¥731,207 million, with the company providing high-performance ceramic products to diverse industries through its global manufacturing and sales network.

Business Model

Automotive-related business functions as a cash cow generating revenue of ¥587,505 million and operating profit of ¥135,302 million (operating margin of 23.0%), and this profit serves as the source of funds for capital expenditure and M&A in the Components & Solutions business (ceramic components for SPE, silicon nitride products, etc.). Replacement products have stable demand linked to the number of vehicles in operation, while original equipment products are based on long-term trading relationships with global automakers. The non-automotive segment is currently in the red, but the company aims to achieve profitability through the gradual decline in PPA amortization expenses and expansion of production capacity.

Company Strengths

The Automotive-related business achieved revenue of ¥587,505 million, operating profit of ¥135,302 million, and an operating margin of 23.0% in FY2026 (ending March 2025). The company has established manufacturing and sales subsidiaries across North America, Europe, China, Southeast Asia, and Brazil, securing global market share in both original equipment and replacement products. Replacement products enjoy structurally stable demand linked to the number of vehicles in operation worldwide.

Building on ceramics and inorganic materials technology accumulated since its founding in 1936, the company has developed a broad range of products spanning from Spark Plugs to Semiconductor Production Equipment Components, IC Packages, Fuel Cells, and Silicon Nitride Products. R&D expenses in FY2026 (ending March 2025) reached ¥26,782 million (¥8,678 million for Automotive-related and ¥18,104 million for Components & Solutions), with continued investment in technology development supporting differentiation from competitors.

The company has executed a series of M&A transactions, including the acquisition of Wells Vehicle Electronics in 2015, the acquisition of CAIRE Inc. in 2018, the formation of a joint venture for NTK Cutting Tools in 2023, and the full consolidation of Toshiba Materials (now Niterra Materials) in June 2025. The acquisition of Niterra Materials increased goodwill and intangible assets by ¥117,931 million, bringing in growth areas such as silicon nitride ceramic balls and heat dissipation substrates for power semiconductors.

ENVALITH's Perspective

The Components & Solutions business is expected to continue posting an operating loss in FY2026 (ending March 2026), with a loss of ¥4,580 million (improved from a loss of ¥6,290 million in the previous fiscal year). In addition to recording PPA amortization expenses associated with the acquisition of Niterra Materials, the company recorded an impairment loss in the oxygen concentrator business of CAIRE Inc. The FY2027 (ending March 2026) forecast plans for the segment to return to profitability with operating income of ¥8,392 million, but achievement remains uncertain depending on the pace of decline in PPA amortization expenses and the recovery trend of the medical device business, warranting close monitoring of progress.

While Automotive-related business accounts for over 80% of revenue, the main products—Spark Plugs and Automotive Sensors—depend on vehicles equipped with internal combustion engines. In China, EV production continues to increase while production of internal combustion engine vehicles remains weak, and the progress of electrification as an external environmental factor represents a mid- to long-term downward pressure on demand. The FY2027 (ending March 2026) forecast for Automotive-related revenue projects growth to ¥623,572 million (up 6.1% year on year), but trends in global internal combustion engine vehicle production volumes will continue to function as an upside/downside factor for performance.

Cash flow used in investing activities in FY2026 (ending March 2026) surged to ¥165,531 million (from ¥34,246 million in the previous fiscal year), mainly due to expenditure of ¥147,486 million for the acquisition of subsidiary shares. As a result of raising ¥99,602 million in long-term borrowings, non-current bonds and borrowings expanded to ¥211,037 million (from ¥139,964 million in the previous fiscal year), and the ratio of equity attributable to owners of the parent declined to 62.8% (from 68.1% in the previous fiscal year). Cash flow from operating activities also decreased to ¥109,384 million (from ¥132,921 million), pressured by an increase in inventories and higher tax payments. The pace of recovery in financial soundness will be a key point for future evaluation.

Growth Strategy

Leveraging Automotive-related earnings as a source of funding, the company is expanding its Ceramics technology across the three domains of "Mobility, Semiconductors, and Environment & Energy"

While capturing sales growth in OE (original equipment) products across all global regions (the U.S., Europe, China, and Japan) and steady demand for aftermarket products, the company is improving its revenue mix through expanded sales of high-value-added products such as Automotive Sensors (up 9.2% year on year). For FY2027 (ending March 2027), the company plans revenue of ¥623,572 million (up 6.1% year on year) and operating profit of ¥141,590 million (up 4.6% year on year) for the Automotive-related business.

In June 2025, the company made Toshiba Materials (now Niterra Materials) a consolidated subsidiary, strengthening its business foundation in Silicon Nitride Products, semiconductor packages, and other areas. Through the gradual decline in PPA amortization expenses and the turnaround of the CAIRE Inc. business, the company plans to achieve a turnaround to operating profit of ¥8,392 million in the Components & Solutions business in FY2027 (ending March 2027). The company will continue to invest actively, with capital expenditure of ¥26,660 million (up ¥1,164 million year on year).

In Ceramics components for semiconductor manufacturing equipment (SPE Business), the company continues to capture investment in production capacity expansion driven by generative AI-related applications and the increasing layer counts of advanced logic semiconductors and memory. Sales remained solid in FY2026 (ending March 2026), and for the FY2027 (ending March 2027) forecast, the company continues to expect to capture demand growth for generative AI and advanced investment associated with increasing memory layer counts.

The dividend policy combines a stable dividend portion with a floor of approximately 4% DOE and a performance-linked portion targeting a payout ratio of 10%. In FY2026 (ending March 2026), the company implemented a dividend of ¥205 per share (payout ratio of 35.9%), and for FY2027 (ending March 2027), it plans a dividend of ¥210 per share (forecast payout ratio of 39.3%). Any excess above the appropriate capital level will also be allocated to share buybacks, aiming to normalize the financial leverage that increased due to the acquisition of Niterra Materials.
