Business

NSK Ltd. (NSK) was founded in 1916 as Japan's first bearing manufacturer, boasting a history of over 100 years. The company operates in three segments: Industrial Machinery Business (bearings for general industry, precision equipment, Condition Monitoring Systems), Automotive Business (Hub Unit Bearings, transmission components, etc.), and Steering Business (electric power steering, etc.). With 90 consolidated subsidiaries and 18 affiliated companies, NSK has built a global manufacturing and sales structure spanning the Americas, Europe, China, ASEAN, and other regions. In September 2025, the company made NSK Steering & Control Corporation a wholly owned subsidiary, bringing the Steering Business into consolidation. Major customers span the industrial sector broadly, including automotive and parts manufacturers, and machine tool and semiconductor manufacturing equipment manufacturers.

Business Model

NSK supplies mechanical components such as bearings, ball screws, and linear guides directly to automotive and industrial machinery manufacturers, underpinned by a global mass-production system based in its own factories. In addition, the company is promoting sales for the aftermarket (repair and replacement parts) and a shift toward a PLM (Product Lifecycle Management) business that combines these with Condition Monitoring Systems. Its structure aims to improve profitability through price pass-through, cost reduction, and enhancing the value-added mix of its product portfolio.

Company Strengths

Since its founding in 1916, the company has accumulated five core technologies: tribology (friction and lubrication), materials technology, analysis technology, mechatronics technology, and production technology. Achievements include the establishment of the "NSK Tribology Collaborative Research Center" with Institute of Science Tokyo (2023) and the commercialization of technology to suppress oxidative degradation of edible oil, among "2025

The company has manufacturing and sales bases in the Americas, Europe, China, ASEAN, India, and other regions, building a global structure comprising 90 consolidated subsidiaries and 18 affiliated companies. It serves diverse industrial customers in Automotive, machine tools, semiconductor manufacturing equipment, energy, and other sectors, diversifying dependence on any specific market. The company has also built up a track record in high-profitability areas such as the Americas aftermarket and semiconductor manufacturing equipment.

In FY2026 (ending March 2026), the net D/E ratio stood at 0.24x, maintaining a sound level well below the target (0.4x or less). The company has obtained an "A" rating from Rating and Investment Information, Inc. and an "A+" rating from Japan Credit Rating Agency, Ltd. It has also secured a ¥40 billion commitment line and a ¥50 billion commercial paper issuance framework, keeping liquidity risk under control.

ENVALITH's Perspective

For FY2026 (ending March 2026), revenue from continuing operations was ¥911,644 million (+14.4% YoY), operating profit was ¥38,812 million (+36.4% YoY), and profit attributable to owners of the parent showed a substantial improvement to ¥22,867 million (+114.8% YoY). However, these results include temporary gains and losses such as a gain on negative goodwill of ¥8,527 million associated with the consolidation of NS&C and a loss on step acquisition of ¥4,662 million, requiring the exclusion of such one-time items to properly assess the underlying earnings level. Restructuring costs in the European business also weighed on operating profit in the Industrial Machinery and Automotive segments.

On May 12, 2026, the company entered into a basic agreement with NTN Corporation regarding a business integration through the establishment of a joint holding company (via share transfer). Both companies, Japan-originated firms centered on bearings with histories spanning over 100 years, decided to integrate in order to respond to a challenging business environment including slowing growth in the Chinese economy, weakness in European manufacturing, and the impact of U.S. tariff policy. Shareholder meeting approval is planned for June 2027, and establishment and listing of the holding company is planned for October 2027; however, uncertainty toward realization remains high, including responses to competition law in various countries, due diligence results, and determination of the share transfer ratio.

The consolidated business forecast for FY2027 (ending March 2027) is revenue of ¥1,000,000 million (+9.7% YoY), operating profit of ¥42,000 million (+8.2% YoY), and profit attributable to owners of the parent of ¥24,000 million (+5.0% YoY). The assumed exchange rates are ¥150 to the US dollar, ¥180 to the euro, and ¥21.0 to the Chinese yuan. As for external factors, while the increase in semiconductor-related capital expenditure driven by expanding AI demand is expected to be a tailwind for the Industrial Machinery Business, the forecast also incorporates risks of decreased sales and rising logistics costs due to escalating tensions in the Middle East; should the impact exceed expectations, a revision to the business forecast may become necessary.

Growth Strategy

Building the growth foundation for the next medium-term management plan through NTN integration, Steering business development, and expansion of AI/EV-compatible products

Entered into a basic agreement in May 2026 to promote management integration through the establishment of a joint holding company (via a share transfer). By combining the technology, quality, and management of both companies, the aim is to build a robust and sustainable business foundation, thereby achieving long-term and profitable growth and securing the position of Japan's industrial base in the world.

In September 2025, NS&C and its subsidiaries were brought into the scope of consolidation, establishing the Steering business as the third reportable segment. In FY2026 (ending March 2026), the Steering business recorded net sales of ¥100,554 million and operating profit of ¥7,730 million (including one-time gains and losses). For FY2027 (ending March 2027), net sales of the Steering business are forecast at ¥170,000 million (+69.1% year on year) with operating profit of ¥4,000 million.

Anticipating increased capital expenditure demand centered on semiconductor-related fields against the backdrop of expanding AI demand, the company is accelerating growth in the Industrial Machinery Business. In addition to steady demand trends in the Americas aftermarket and for semiconductor manufacturing equipment, the company is promoting expanded sales of high-value-added products such as Condition Monitoring Systems. For FY2027 (ending March 2027), net sales of the Industrial Machinery Business are forecast at ¥400,000 million (+6.0% year on year), with operating profit of ¥22,000 million (+75.1% year on year).

Strengthening the profit base of the Automotive Business by expanding EV/HEV-compatible products such as Ball Screws for Electro-Hydraulic Brake Systems and low-torque bearings. Continuing to promote the pass-through of tariffs into selling prices, securing the effect of increased revenue in the Americas. For FY2027 (ending March 2027), net sales of the Automotive Business are forecast at ¥400,000 million (-0.8% year on year), with operating profit of ¥18,000 million (+3.6% year on year).

In response to the deterioration of market conditions in the European manufacturing industry, the company is promoting structural reform of its European business in the Industrial Machinery and Automotive segments. In FY2026 (ending March 2026), one-time expenses were recorded, but the company aims to improve its medium- to long-term profitability through the completion of structural reform. Under the next medium-term management plan (with FY2027 (ending March 2027) as its first year), the company plans to promote further profit improvement and transformation of its product portfolio.
