Business

Yamau Holdings Co., Ltd. is a holding company headquartered in Fukuoka City with 8 consolidated subsidiaries. Centered on its core Concrete Products Manufacturing & Sales Business (Civil Engineering Products, Landscape Products, Resin Concrete Products), the group operates across 7 segments: Sluice Gate & Weir Manufacturing, Construction & Maintenance Business; Geological Survey & Consulting Services and Civil Engineering Construction Business; Expansion Joint Manufacturing, Sales & Installation Business for Bridges and Elevated Roads; Concrete Structure Inspection, Survey & Repair Construction Business; Information Equipment Sales & Maintenance Business; and Real Estate Business. Its main customers are public sector clients such as national and local governments, and it is a comprehensive social infrastructure solutions company that captures demand for disaster prevention, disaster mitigation, and aging infrastructure renewal, with Kyushu as its primary market. It transitioned to a holding company structure in April 2021, and has been promoting stronger group governance and business diversification.

Business Model

Built on a foundation of build-to-forecast production and sales of concrete products, the company provides an integrated offering spanning made-to-order production and construction of sluice gates, bridge expansion joints, and similar products, through to after-sales services such as inspection, repair, and maintenance. With public investment as its primary source of demand, the business structure combines one-off revenue from product sales with recurring, stock-type revenue accumulated through maintenance, inspection, and repair construction work. The Real Estate Leasing Business, which includes intra-group leasing, functions as a stable source of income.

Company Strengths

In FY2026 (ending March 2026), the operating margin of the Concrete Products Manufacturing & Sales Business was 21.4% (up 1.5 points year on year). Through promoting the pass-through of material, raw material, and logistics cost increases to sales prices, along with efforts to reduce manufacturing costs and general administrative expenses, segment profit was secured at ¥2,600 million, up 3.3% year on year, even as net sales declined 3.6% year on year.

The company operates seven segments: Concrete Products, Sluice Gates & Weirs, Geological Survey, Bridge Expansion Joints, Inspection & Repair, Information Equipment, and Real Estate. In FY2026 (ending March 2026), even as the Bridge Expansion Joints segment recorded an operating loss, the Geological Survey segment achieved operating profit growth of 102.0% year on year and the Inspection & Repair segment achieved growth of 92.9% year on year, maintaining consolidated group operating profit at ¥3,544 million.

As of the end of FY2026 (ending March 2026), the company held cash and cash equivalents of ¥4,888 million, while interest-bearing debt remained limited at ¥3,261 million, maintaining a net cash position. Net assets expanded 11.5% year on year to ¥13,791 million, providing capacity to respond to M&A and capital expenditure needs.

ENVALITH's Perspective

In FY2026 (ending March 2026), net sales came to ¥21,244 million (down 7.0% year on year), while operating profit was maintained at ¥3,544 million (down 0.6% year on year), and the operating profit margin improved to 16.7% (from 15.6% in the previous period). The skillful cost management can be evaluated positively. On the other hand, the Expansion Joint Manufacturing, Sales & Installation Business for Bridges and Elevated Roads fell into an operating loss of ¥196 million after goodwill amortization, due to the combined impact of the end of large-scale special demand and road traffic restrictions related to the Osaka-Kansai Expo. The timing of profitability recovery in this business and order trends after the Expo will be key points to watch going forward.

The consolidated business forecast for FY2027 (ending March 2027) calls for net sales of ¥22,200 million (up 4.5% year on year), operating profit of ¥3,520 million (down 0.7% year on year), and net profit of ¥2,250 million (up 1.7% year on year). Sales are expected to recover to the FY2025 (ended March 2025) level, but operating profit is forecast to decline slightly, suggesting a conservative stance. As an external factor, the government's disaster prevention, mitigation, and national resilience budget remains solid, but public investment is expected to gradually decline over the medium to long term, and the risk that trends in public sector order volume in Kyushu, the company's primary market, will affect business performance continues.

In FY2026 (ending March 2026), the company conducted share buybacks totaling ¥152 million (a substantial increase from ¥0.1 million in the previous period), and while the annual dividend was reduced to ¥110 (from ¥119 in the previous period), the payout ratio was maintained at 30.3%. For FY2027 (ending March 2027), the forecast dividend is ¥112, continuing a policy of maintaining a payout ratio of around 30.2%. Net assets per share increased to ¥2,273.71 (from ¥2,019.74 in the previous period), with a net asset dividend rate of 5.1%. The balance between accumulating retained earnings and returning capital to shareholders appears well-managed, but the decline in earnings per share to ¥363.60 (from ¥393.61 in the previous period) warrants close attention.

Growth Strategy

As the 1st Stage of Long-term VISION2035, the company is promoting structural reform, deepening existing business areas, and creating new sources of revenue.

Positioned as the period of "Challenge toward Transformation and Creation," the group is pursuing structural reform and growth strategy. It is advancing groundwork and organizational development aimed at solidifying existing business areas and creating new pillars of profit, targeting net sales of ¥22,200 million and net income of ¥2,250 million in FY2027 (ending March 2027).

Continuing to pass on rising material, raw material, and logistics costs to sales prices. In FY2026 (ending March 2026), despite a decline in sales in the Concrete Products business, segment profit increased 3.3% year on year, and the group's overall operating margin improved by 1.1 points year on year.

An operating loss of ¥196 million after goodwill amortization was recorded in FY2026 (ending March 2026) due to the end of large-scale special demand and the impact of road traffic restrictions from the Osaka-Kansai Expo. Challenges include the recovery of order volumes from local governments in the Osaka area after the Expo ends and improving profitability by promoting the pass-through of material cost increases to sales prices. Recovery in FY2027 (ending March 2027) is a focus area.

Under the "Yamau Group Long-term VISION2035," targeting the year 2035, the company aims not only to deepen existing business areas but also to create new sources of revenue. It is nurturing growth segments such as the Geological Survey & Consulting Services and Civil Engineering Construction Business (profit up 102.0% year on year) and the Concrete Structure Repair business (up 92.9% year on year), aiming to diversify the group's overall revenue base.
