JMACS Japan Co., Ltd.

Business Details

JMACS Corporation is a wire-specialist manufacturer engaged in the manufacture and sale of Fire Prevention Wire, Communication Cable, Instrumentation & Control Cable, and Other Low-Voltage Wire. Its main market is domestic, and its key customer is Senshu Densyo Co., Ltd. (accounting for approximately 39% of sales in FY2026 (ending February 2026)). The company's strength lies in short-lead-time response (speed and technology), and it focuses on winning orders for plant projects, FA (factory automation), and instrumentation cable, as well as improving profit margins. From FY2025 (ending February 2025), it changed to a single segment structure of the "Electric Wire Business."

Recent Overview

Capturing semiconductor and capital investment demand, Q1 net sales and operating profit increased significantly

In the first quarter of FY2027 (ending February 2027) (March–May 2026), the company achieved significant growth in both revenue and profit, with net sales of ¥1,647 million (up 26.5% year on year), operating profit of ¥227 million (up 238.8% year on year), and quarterly net income of ¥161 million (up 209.4% year on year). The company actively captured demand from the substantial expansion of the semiconductor industry and capital investment in domestic factories, with orders for plant projects, FA (factory automation), and instrumentation cable remaining solid. Although concerns continue regarding price increases and material procurement for crude-oil-derived products due to the closure of the Strait of Hormuz, the company leveraged its strength in short-lead-time response to drive performance. There has been no change to the full-year earnings forecast (net sales of ¥6,300 million, operating profit of ¥329 million), and the first-quarter operating profit of ¥227 million represents approximately 69% of the full-year forecast.

Key Products

Growth Drivers

• Increased orders driven by substantial expansion of demand in the semiconductor industry
• Active capture of capital investment demand from domestic factories and other facilities
• Solid trend in orders for plant projects, FA (factory automation), and instrumentation cable
• Differentiation from competitors through strength in short-lead-time response (speed and technology)
• Improved profit margins through cost reduction, multi-skilled workforce development, and productivity improvement
• Expanded orders through capture of active investment demand, including for data centers

Risks

• Risk of sales concentration in the key customer (Senshu Densyo Co., Ltd.), which accounts for approximately 39% of sales
• Risk of price surges and material procurement issues for crude-oil-derived products due to closure of the Strait of Hormuz
• Risk of raw material price increases due to Middle East dependence for naphtha and crude oil
• Demand fluctuations due to geopolitical risks such as US-China tensions, US tariff policy, and Middle East conditions
• Risk of rising production costs due to labor shortages and higher material prices
• Uncertainty over whether the strong first-quarter performance can be sustained through the full year, given the forecast of a significant full-year operating profit decline to ¥329 million (down 34.4% year on year) in FY2027 (ending February 2027)
