The business consists of four segments: the Building Materials Business (building materials for commercial buildings, residential building materials, and exterior products), the Materials Business (aluminum and magnesium casting, extrusion, and processing), the Commercial Facilities Business (store fixtures, signboards, and maintenance), and the International Business (aluminum extrusion in Europe, Thailand, and China). Major customers span construction companies, homebuilders, retailers, and automotive-related manufacturers, and the company supplies materials and products to a wide range of industries both domestically and internationally. Consolidated net sales for FY2025 (ended May 2025) were ¥359,424 million. Listed on the Prime Market of the Tokyo Stock Exchange.

Business Model

In the Materials Business, the company operates an integrated production model spanning aluminum and magnesium casting through extrusion and processing, supplying these materials and extruded shapes internally to the Building Materials Business and International Business while also selling to external customers. In the Building Materials Business, residential, commercial building, and exterior building materials are sold through a nationwide distribution network of agents and sales companies, while the Commercial Facilities Business secures recurring revenue by providing one-stop services from fixture manufacturing to construction and 24/7/365 maintenance. In the International Business, high value-added aluminum extruded products are supplied globally from bases in Europe, Thailand, and China.

Company Strengths

In the Materials Business, the company possesses one of the largest domestic integrated systems encompassing alloy casting, shape extrusion, and processing. Production results for the Materials Business in FY2025 (ended May 2025) totaled ¥51,320 million (110.6% year on year). The company continues aggressive capital investment, including the introduction of extrusion presses and processing lines aimed at expanding into the automotive field (capital investment in this business of ¥4,282 million).

The company holds a top-class share of the industry in both Store Display Fixtures & Showcases and signboards, and has built a maintenance network providing uniform nationwide service along with a 24-hour, 365-day response system. Commercial Facilities Business sales in FY2025 (ended May 2025) reached a record high of ¥44,522 million (up 4.3% year on year), steadily capturing inbound demand.

In 2015, the company acquired the European Aleris extrusion business, and has expanded production bases in Germany, Austria, the United Kingdom, Thailand, China, and Singapore. International Business sales totaled ¥76,145 million (FY2025, ended May 2025). In the ASEAN region, the company has carried out capacity expansion investments (capital investment of ¥4,995 million) in response to robust demand, capturing new demand in fields such as electronic devices.

ENVALITH's Perspective

Net loss attributable to owners of parent for FY2026 (ending May 2026) expanded sharply to ¥13,498 million from the prior period's loss of ¥2,336 million. The main cause was the recognition of an impairment loss of ¥16,761 million on fixed assets in the Building Materials Business, triggered by the surge in aluminum ingot prices amid heightened Middle East tensions. On a non-consolidated basis, the company also posted a net loss of ¥19,712 million, and the equity ratio fell to 22.4%. Retained earnings declined to ¥10,227 million, raising concerns about a shrinking financial buffer.

Operating profit for FY2026 (ending May 2026) came to ¥1,546 million (+0.1% YoY), exceeding the plan (¥1,000 million), but the operating profit margin remained at just 0.4%. Interest expenses of ¥1,998 million exceeded operating profit, and ordinary profit stayed at only ¥882 million (-6.6% YoY). The operating profit margin has remained below 1% for five consecutive periods, calling into question the effectiveness of profit structure reforms.

The consolidated earnings forecast for FY2027 (ending May 2027) projects net sales of ¥390,000 million (+9.1% YoY) and operating profit of ¥4,000 million (+158.7% YoY), anticipating a significant recovery. This assumes a rebound from the pullback following the rush demand ahead of the revised Building Standards Act, as well as a recovery in renovation demand driven by the "Housing Energy Conservation 2026 Campaign." On the other hand, prolonged high aluminum ingot prices stemming from Middle East tensions and delayed recovery at the European subsidiary remain downside risks.

Growth Strategy

Prioritizing revenue structure reform, capturing growth in Materials Business automotive field, European subsidiary reform, and residential energy-saving demand

Promoting cost reduction through revenue structure reform and price optimization including price revisions. In FY2026 (ending May 2026), net sales decreased 6.2% year on year, but operating profit improved significantly to ¥1,069 million (up 352.2% year on year). The company will continue to expand sales of the highly insulated slim window "STINA" and capture renovation demand.

Against the backdrop of demand for lighter vehicle bodies, a new large-scale extrusion line was added at the Shinminato-higashi Plant. Net sales increased 13.3% year on year due to higher sales volume in the transportation sector. However, operating profit decreased 9.6% year on year due to a sharp rise in aluminum ingot and other material prices caused by the situation in the Middle East.

Promoting cost reductions including manufacturing expenses at European subsidiaries that continue to underperform. The International Business operating loss for FY2026 (ending May 2026) was ¥2,433 million, a modest improvement from the previous period (¥2,598 million). A decline in volume in the transportation sector, including automotive, rail, and aviation, remains a challenge. The company has stated that the reform is progressing as planned and it expects a profit contribution in FY2027 (ending May 2027).

Promoting the reduction of fixed and indirect costs, streamlining of operations and organizational structure, and optimization of the manufacturing structure as the five initiatives of the medium-term management plan. In FY2026 (ending May 2026), selling, general and administrative expenses were ¥68,966 million, only a slight increase from the previous period (¥68,219 million), with limited effect from major cost reductions. Further fixed cost reduction is required toward FY2027 (ending May 2027).

Aiming to expand sales of energy-saving building materials such as highly insulated windows, supported by subsidy measures such as the "Housing Energy Conservation 2026 Campaign." The number of newly started housing units in FY2026 is expected to recover from the previous year's decline, which is anticipated to serve as a favorable external environment for the recovery of Building Materials Business net sales.
