SIM Technology Group's (HKG:2000) revenue from its core business fell 37% to HK$18.7 million in September from HK$29.6 million a year prior, a Monday Hong Kong bourse filing said.
The mobile communications company recorded a total revenue of HK$21.7 million in September, up 12% from HK$19.4 million in August.
For the nine months ended Sept. 30, total revenue reached HK$270.4 million, down 7.6% from HK$292.5 million in the year-ago period.
The changes in revenue were attributed to adjustments by customers in the delivery time of their purchase orders.
