(Stock code: 1982)
Earnings Presentation for the First Half of the Fiscal Year Ending March 31, 2026 November 11, 2025Net sales and profit increased YoY.
Orders received remained steady, with large projects secured in every category, including data centers/information, driven by ongoing strategic sales activities.
Net sales increased YoY, due partly to steady progress of projects carried over from the previous fiscal year.
Profit margin increased due to improvements in projected profit at the time of receiving orders, as well as in the profitability of construction projects completed, resulting in a YoY increase in each line-item profit.

Financial Highlights (Consolidated)
To date, no change has been made to the forecast announced on May 13.
Strategic sales activities will continue to be implemented to ensure steady progress toward achieving the full-year
forecast for orders received.
Sales performed well in the first half, but no revision is made to the net sales forecast. This is mainly due to the pull-forward impact of net sales recognized in the first half, and the risk of potential extensions of construction periods.
Profits were healthy in the first half, but forecasts are kept unrevised in consideration of risks in the second half.

8th Medium-term Management Plan Initiatives
The importance of cooling technologies and energy-saving measures in response to hyperscale data center expansion
The expansion of hyperscale data centers is driving higher power consumption, which in turn increases exhaust heat.
Traditional air cooling has reached its technical limits, and energy-saving measures require reconsideration.

Power consumption per rack | 2-4 kVA | 6-8 kVA | 20-150 kVA | max. 200 kVA |

Company Highlights
Continuing to focus on the DC field in line with the expansion of hyperscale DC construction
Trends in DC
Features of DC construction
Driven by digitalization and generative AI, hyperscale DC construction is expanding in the Tokyo metropolitan area and the Kansai region, with strong construction demand expected to continue for the foreseeable future.
Regional data center construction is underway.
The Group's advantage
Leveraging expertise and experience gained through
the construction of telecommunications buildings.
Compared to other property types such as offices and hotels, the share of facility work is higher, and the specifications are more clearly defined.
Construction can be completed in a short period of time especially for the fitting out* process as specifications are mostly set at the outset.
DX (use of BIM etc.) can improve installation efficiency (unit construction method or front-loading approach).

* "Fitting out" refers to construction that makes the interior of a building usable, while "core and shell" refers to the basic structural construction.
Initiatives for Data Center (DC) Construction (1)
Promoting open innovation through the Data Center Trial Field
In November 2024, the Data Center Trial Field was established within the Noda Technical Research Center in partnership with NTT Data as a facility to verify next-generation cooling technologies for data centers and promote open innovation and collaboration.
Challenges faced by hyperscale DCs
Improve cooling efficiency
Reduce energy
Improve reliability and maintainability
Verifying efficient cooling technologies (water and liquid cooling) and energy-saving technologies to respond to the high heat generation and increased power consumption.
Understanding the characteristics of heat sources and server cooling systems, and validating facility/equipment construction
Promoting collaboration with diverse participants
Air conditioner manufacturers
Design and construction companies
Heat source equipment manufacturers
Immersion cooling manufacturers
IT vendors
Piping and materials manufacturers
9 participating companies (as of September 2025)
