Business Details

Centered on magnesium, the lightest practical metal, the company maintains an integrated manufacturing system spanning Mold Design & Manufacturing through casting, machining, painting, and assembly. Major customers include Mitsubishi Electric, AXIS COMMUNICATIONS AB, CBC, and Koshin Kogyo. Product applications range across mirrorless cameras, automobiles, network cameras, printers, medical devices, and drones. The company has global production sites in Japan, China, Thailand, and Malaysia, and in September 2025 made E-Cast Industries Sdn. Bhd., an aluminum die-casting manufacturer in Penang, Malaysia, a subsidiary, establishing a two-site structure in Malaysia.

Recent Overview

Net sales increased, but profit declined significantly due to higher SG&A expenses and M&A-related costs

In FY2026 (ending March 2026), net sales reached ¥6,815 million (up 6.1% year on year), but selling, general and administrative expenses swelled to ¥1,282 million (up 23.5% year on year), causing operating profit to fall sharply to ¥337 million (down 30.5% year on year). Declining sales of automotive parts due to weak EV demand affected the standalone results. Meanwhile, in September 2025, the company made E-Cast Industries Sdn. Bhd. (Penang, Malaysia; aluminum die-casting) a wholly owned subsidiary for ¥2,145 million, recording goodwill of ¥650 million. The acquisition was funded through long-term borrowings of ¥2,039 million and the issuance of ¥500 million in preferred shares, expanding total assets to ¥9,639 million (up 44.9% year on year).

Key Products

Growth Drivers

• Aggressive M&A and capital investment strategy aimed at achieving the medium-term management plan "Challenge 100" (final year FY2028, ending March 2028) targets of consolidated net sales of ¥12.0 billion and operating profit of ¥1.2 billion
• Synergy effects from establishing a two-site structure in Malaysia (Penang and Johor) through the E-Cast Industries Sdn. Bhd. subsidiary acquisition, including mutual complementation of production capacity and reduction of outsourcing costs
• Increased orders related to precision equipment at the China site and expanding orders related to network cameras at the Malaysia site
• Growing strategic importance of the Malaysia site amid global supply chain restructuring (production shift from China to ASEAN)
• Medium- to long-term expansion of demand for lightweight automotive parts driven by EV/HV adoption, and increasing demand for precision parts in the semiconductor and electronics fields
• Potential for increased revenue and profit by utilizing E-Cast's spare production capacity (approximately 50%) in its die-casting division
• Active consideration of additional M&A opportunities in Japan and ASEAN, targeting highly profitable companies and business turnaround cases

Risks

• Sharp decline in operating margin (from 7.5% to 4.9%) due to a rapid increase in selling, general and administrative expenses (¥1,282 million in FY2026, up 23.5% year on year)
• Rising financial leverage and increased interest burden (interest expense of ¥87 million) due to a sharp increase in interest-bearing debt (total short- and long-term borrowings of ¥4,708 million) associated with M&A and capital investment
• Risk that the final goodwill amount and amortization burden may change, as the purchase price allocation for E-Cast Industries Sdn. Bhd. has not been finalized (goodwill of ¥650 million is a provisional figure)
• Decline in sales of automotive parts due to weak EV demand (standalone net sales down 3.4% year on year), and recording of an allowance for doubtful accounts related to receivables from the Thai subsidiary
• Impact on the global supply chain from foreign exchange risk (translation losses on overseas subsidiaries' results during yen appreciation) and geopolitical risk (U.S. trade policy, Middle East situation, Russia-Ukraine situation)
• Risk of sales concentration in major customers such as Mitsubishi Electric, AXIS COMMUNICATIONS AB, CBC, and Koshin Kogyo
• Safety management costs stemming from the risk of magnesium ignition and explosion, and the risk of major manufacturers withdrawing from the business
