Key Products
Growth Drivers
- Steady trends in private-sector capital investment in growth areas such as semiconductor plants, data centers, and medical facilities
- Continued demand from redevelopment projects centered on major metropolitan areas
- A high-level build-up in the next-period carry-forward backlog to ¥49,431 million, driven by orders received of ¥53,954 million (up 3.9% year on year)
- Stable order intake for renovation work driven by ongoing demand for equipment upgrades and energy-saving renovations in existing buildings
- Promotion of expansion into advanced engineering fields and maximization of stock-type revenue under the new medium-term management plan "LIVZON DREAM 2030 2nd half!"
Risks
- Construction costs remaining at elevated levels due to persistently high materials and equipment prices and rising labor costs
- Constraints on construction capacity due to chronic shortages of engineers and skilled workers
- Ongoing burden of goodwill amortization (¥102 million in the current period)
- The impact of declining real income due to yen depreciation and rising prices on domestic demand and private-sector capital investment
- Impact on materials and equipment procurement costs from unstable international conditions and exchange rate movements
