Business Details

The Daidan Co., Ltd. Group operates as a single segment in the facility construction business, encompassing the design, supervision, and construction of HVAC & Sanitary Construction and Electrical Construction. Its primary customers include factories, data centers, medical-related facilities, and redevelopment projects, with operations spanning not only Japan but also overseas markets such as Singapore, Thailand, and Vietnam. In FY2026 (ending March 2026), completed construction revenue came to ¥256,228 million (down 2.5% year on year), a slight revenue decline, but operating profit rose to ¥34,479 million (up 49.7% year on year), reaching a record high level on the back of a significant improvement in gross profit margin on completed construction.

Recent Overview

Despite a slight decline in revenue, accelerating profitability improvements drove both operating profit and net profit to record highs

In FY2026 (ending March 2026), completed construction revenue declined slightly to ¥256,228 million (down 2.5% year on year), but gross profit on completed construction rose substantially to ¥56,083 million (up 35.6% year on year). Improved profitability drove a sharp rise in operating margin to 13.5% (from 8.8% in the prior period). Orders received increased significantly to ¥353,102 million (up 25.5% year on year), and the period-end backlog reached a record high of ¥355,273 million (up 37.5% year on year). Orders in the Electrical Construction segment expanded rapidly, up 94.8% year on year, while overseas construction also grew rapidly, with completed construction revenue up 72.8% year on year. Operating cash flow improved significantly to ¥58,437 million (from ¥12,402 million in the prior period), and while short-term borrowings were reduced by ¥20,125 million, the cash balance increased to ¥81,925 million. The dividend policy was revised to "a payout ratio of 40% or more, with a minimum DOE of 4.8%," and the total dividend amount for FY2026 (ending March 2026) increased to ¥10,849 million (from ¥7,032 million in the prior period). For FY2027 (ending March 2027), the company forecasts completed construction revenue of ¥265,000 million and operating profit of ¥36,000 million.

Key Products

service
HVAC & Sanitary Construction

The core segment, accounting for 80.8% (¥206,994 million) of completed construction revenue. It handles air conditioning, water supply and drainage, and sanitary facilities for factories, data centers, medical facilities, and commercial facilities. Orders received expanded to ¥265,798 million (up 12.4% year on year), and the backlog also grew to ¥282,240 million (up 26.3% year on year).

service
Electrical Construction

Accounting for 19.2% (¥49,234 million) of completed construction revenue, this segment grew rapidly, up 31.2% year on year. Orders received nearly doubled to ¥87,303 million (up 94.8% year on year), and the backlog also increased substantially to ¥73,033 million (up 108.9% year on year). The share of the Electrical Construction segment in both orders and backlog is expanding, reflecting an ongoing shift in the business portfolio.

service
Overseas Facility Construction

Completed construction revenue expanded rapidly to ¥33,840 million (up 72.8% year on year), accounting for 13.2% of total completed construction revenue. Orders received reached ¥65,288 million (up 63.7% year on year), and the backlog stood at a high level of ¥66,140 million (up 90.6% year on year). The effect of consolidating Presico Engineering Pte. Ltd. as a subsidiary also contributed.

service
Renewal Construction

Completed construction revenue expanded to ¥108,793 million (up 26.3% year on year), accounting for 42.5% of total completed construction revenue. Orders received came to ¥133,407 million (up 20.2% year on year), and the backlog reached ¥87,984 million (up 38.8% year on year). Stable growth continues, underpinned by demand for the renewal of aging facilities.

service
Industrial Facility Construction

Completed construction revenue was roughly flat at ¥135,163 million (down 1.9% year on year), accounting for 52.8% of total completed construction revenue. Orders received declined to ¥130,501 million (down 19.8% year on year), reflecting the impact of changes in facility plans for large-scale projects. The backlog stood at ¥139,914 million (down 3.2% year on year).

Growth Drivers

  • Contribution to next-period results from the rapid expansion of the Electrical Construction segment (orders received up 94.8% year on year, backlog up 108.9%)
  • Rapid growth in overseas construction (completed construction revenue up 72.8% year on year, backlog up 90.6%) and the continuing consolidation effect of Presico Engineering
  • Expansion of demand for Renewal Construction (completed construction revenue up 26.3% year on year, backlog up 38.8%)
  • Improved visibility into next-period performance due to the buildup in period-end backlog to ¥355,273 million (up 37.5% year on year)
  • Continued improvement in profitability (rising gross margin on completed construction, significant decrease in provision for losses on construction contracts)
  • Continued strong trend in orders for data centers, semiconductor plants, and medical-related facilities
  • Enhanced shareholder returns through a strengthened dividend policy (minimum DOE of 4.8%)

Risks

  • Constraints on construction capacity due to worsening labor shortages (being addressed through increased hiring and investment in training and education)
  • Orders received for Industrial Facility Construction declined 19.8% year on year, posing a risk related to changes in facility plans for large-scale projects
  • Uncertainty over U.S. tariffs and foreign exchange rates affecting facility plans for large-scale projects in the industrial facility segment
  • Risk of rising costs due to increases in material and equipment prices and labor costs
  • A valuation loss on investment securities of ¥570 million was recorded, indicating exposure to fair value fluctuation risk on held securities
  • Cash flow risk inherent to the facility construction business, where expenditures precede receipts (increased advance payments on large-scale projects)
  • Risk of increased burden on construction management and quality control accompanying the rapid buildup in backlog
  • Accounting estimate change risk, as seen in the revision of estimates for asset retirement obligations (¥456 million recorded)
