Struggling retailer Daiei Inc. said Friday its group net profit plunged 98.4 percent to 2.3 billion yen in the business first half due to the absence of a hefty one-time gain booked a year ago.

Revenue fell 14.8 percent to 992.08 billion yen, falling short of the firm's own target by 2.9 billion yen.

Even excluding extraordinary items, Daiei's struggle was apparent during the March-August period.
