    Question

    Asked for an outlook on new equipment sales by application, focusing on the reasons for the expected recovery in sales to NAND customers in the second half of the fiscal year, and whether new NAND-related applications are driving this trend.

    The executive clarified that while full-fledged NAND investment is expected next year, the current fiscal year's sales outlook is based on long-term investment plans already shared by NAND customers.
