Business

Sansho Electric Co., Ltd. is a motor and pump specialty manufacturer founded in 1957, listed on the TSE Standard Market. The company is composed of the parent and five consolidated subsidiaries, with its core business being the manufacture and sale of motors, pumps, and motor application products and components. Pumps for Semiconductor Manufacturing Equipment are the main application, and orders have been increasing against the backdrop of growing demand related to generative AI. In addition to domestic manufacturing bases, the company has a local subsidiary in Shanghai, China (Shanghai Sansho Electric Co., Ltd.), supplying products to customers both domestically and internationally. In February 2026, the company newly established Kasai Sansho Electric Co., Ltd., incorporating metal product processing operations, strengthening in-house production within the group. Major customers are centered on industrial equipment and semiconductor equipment manufacturers, including SMC Corporation (11.1% of net sales).

Business Model

A vertically integrated business model that handles everything from motor and pump design to manufacturing and sales. Group companies share responsibilities for parts processing, assembly, stator manufacturing, and other processes, achieving both cost efficiency and quality control. The company's strength lies in its ability to provide custom designs tailored to customer requirements, generating revenue by supplying high-value-added products primarily for semiconductor manufacturing equipment applications. The company places emphasis on the ordinary income to net sales ratio as a key management indicator, and continuously implements selling price revisions and cost reductions.

Company Strengths

The company has continuously expanded the usable liquid temperature range for PDH-type pumps used in semiconductor manufacturing applications, enhancing its ability to respond to new processes in the market. In FY2026 (ending March 2026), orders for pumps for semiconductor manufacturing equipment exceeded expectations, and sales performance in the Pump segment recorded high growth of 118.0% year-on-year.

Multiple consolidated subsidiaries, including Okayama Sansoh Electric, Shingu Sansoh Electric, Sanso Seiko, and Shanghai Sansoh Electric, handle component processing, assembly, and stator manufacturing, establishing an integrated production system within the group. In February 2026, the company newly established Kasai Sansoh Electric Co., Ltd. and incorporated the metal products processing business of Ishino Seisakusho, further strengthening in-house production capabilities.

The company operates a rigorous verification process combining CAE analysis technologies for structural, fluid, and magnetic field analysis with evaluation equipment, achieving the development of products with high reliability even under harsh usage environments. Research and development expenses amounted to ¥470 million in the fiscal year under review, and the company is also advancing technological expansion into new fields such as specialty pumps and application unit products.

ENVALITH's Perspective

Net sales for FY2026 (ending March 2026) reached ¥18,292 million (up 14.1% year on year), and operating profit surged to ¥794 million (roughly 11 times the prior-year level), marking a substantial recovery. The main external driver was that orders for pumps used in semiconductor manufacturing equipment increased beyond expectations amid expanding demand related to generative AI. For FY2027 (ending March 2027), the company forecasts further growth, with net sales of ¥18,800 million (up 2.8% year on year) and operating profit of ¥1,300 million (up 63.6% year on year), though close attention is warranted regarding whether geopolitical risks and uncertainty over U.S. trade policy could affect the sustainability of demand.

The operating profit margin recovered sharply from 0.4% in FY2025 (ended March 2025) to 4.3% in FY2026 (ending March 2026), and is expected to improve further to around 6.9% in the FY2027 (ending March 2027) forecast. On the other hand, the company's high dependence on a specific application and specific customers in the semiconductor manufacturing equipment field has revealed a structural vulnerability whereby performance can swing significantly during downturns in the semiconductor market (operating profit plunged to ¥69 million in FY2025 (ended March 2025)). Diversifying customers and applications is a medium- to long-term challenge.

The annual dividend for FY2026 (ending March 2026) was ¥25 per share (payout ratio of 20.1%), a significant decline from the prior period's 96.2%, normalizing to a level commensurate with earnings. The FY2027 (ending March 2027) forecast maintains the ¥25 dividend (projected payout ratio of 13.5%). The dividend-to-net-assets ratio remains low at 0.9%. Retained earnings stand at a substantial ¥8,788 million, providing ample financial capacity for shareholder returns, but clarifying the policy toward expanding shareholder returns (such as dividend increases or share buybacks) could become a point of investor interest.

Growth Strategy

Capturing growth in the semiconductor market and diversifying revenue through unit products and new customer development

In response to increased capital expenditure by semiconductor manufacturing equipment makers, driven mainly by generative AI–related demand, the company has strengthened its supply capabilities for Pumps for Semiconductor Manufacturing Equipment & Industrial Pumps. In FY2026 (ending March 2026), orders exceeded expectations, achieving a significant recovery in both revenue and profit.

To respond to changes in the business environment, the company has continuously worked on revising sales prices and reducing costs, improving the operating profit margin from 0.4% in FY2025 (ending March 2025) to 4.3% in FY2026 (ending March 2026). The FY2027 (ending March 2027) forecast anticipates further improvement in the profit margin.

Through product planning and development of Motor & Pump Application Unit Products, the company aims to develop new customers and diversify its revenue structure to reduce dependence on specific customers and applications. It continues to promote improved product satisfaction and expansion to new customers.

In preparation for further growth in the semiconductor manufacturing equipment market, the company continues its efforts to strengthen its production system and stabilize procurement of raw materials and components, addressing geopolitical risks and supply disruption risks through procurement stabilization.
