Overview of consolidated management indicators, etc. (operating results)

(Millions of yen)

Business environment and the Company's performance summary

• Net sales of construction contract orders received reached a record high due to orders received for large-scale construction projects overseas.

• Net sales of completed construction contracts showed a reactionary decline from the previous period, when large-scale construction projects were underway.

• Gross profit on completed construction contracts increased as profitability improved, supported by greater customer understanding of appropriate price pass-through.

  As a result of the above, we posted higher profits in all profit categories.
