In terms of the consolidated operating results for fiscal 2022, net sales are expected to be 26,500 million yen (down14.0% from the previous forecast) mainly due to the postponement of certain projects to the next fiscal year. With regard
to profit and loss, as there is no change from the previous forecast, operating profit and ordinary profit are both expected
to be 1,200 million yen, and profit attributable to owners of parent for fiscal 2022 is expected to be 700 million yen.
As for the non-consolidated operating results, net sales are expected to be 26,000 million yen (down 14.2% from theprevious forecast) for the same reason as consolidated operating results, while there is no change in profit and loss fromthe previous forecast, with operating profit and ordinary profit both expected to be 1,200 million yen and net profit
expected to be 700 million yen.
