ASMPT (HKG:0522) posted a net loss of HK$268.6 million, or HK$0.65 per basic share, in the third quarter ended Sept. 30, reversing a net profit of HK$23.8 million a year earlier.

The swing to loss reflected restructuring costs and inventory write-offs totaling HK$370.5 million, mainly linked to the voluntary liquidation of subsidiary ASMPT Equipment (Shenzhen), according to a Tuesday filing to the Hong Kong Stock Exchange.

The chip gear maker's quarterly revenue rose 9.5% year over year to HK$3.66 billion, while bookings increased 14.2% to HK$3.62 billion.

For the fourth quarter, ASMPT expects to generate between $470 million and $530 million in revenue.
