FY ending Mar 2025 → FY ending Mar 2026

Revenue for FY ending Mar 2026 fell 2.2% to ¥487.7B, down from ¥498.6B.
Profits moved the other way: gross profit rose 39.0% to ¥53.2B, and operating income rose 89.5% to ¥27.1B.
Net income attributable to owners rose 114.5% to ¥20.1B, and operating cash flow climbed 203.9% to ¥25B.

In building construction, the drag from loss-making contracts won during the COVID period faded, and newer jobs priced with better margins progressed smoothly.
Sales fell because some subsidiaries had fewer projects on hand and because large projects had moved ahead strongly in the prior year.
Civil engineering sales grew thanks to approved design changes, but its profit fell because the prior year had included some unusually profitable jobs.

If material or labor costs rise after a contract is signed, private-sector clients may not agree to pay more, leaving the company to absorb the extra cost.
A shortage of skilled workers and engineers could push up labor costs and force the company to skip some bids, cutting new orders.
If construction spending in Japan starts to shrink, tougher competition could reduce orders and squeeze project margins.
