These are items the company does not state in this document. We do not leave them blank, nor fill them in from other sources or by inference.

The reasons the company gives

The company's own explanation, not something inferred from the numbers.

The upward revision to the full-year earnings forecast reflects the consolidation of 水ing from the second quarter and a review of business profit. The first quarter's increases in revenue and profit were driven by the integration of 三井住友建設, growth across the businesses, completion of highly profitable projects, higher profit margins at the time of order receipt, and the pass-through of higher prices. The increase in the dividend was attributed to growth in net income and EPS.
