According to semiconductor industry sources, ASE's capacity utilization rate will decline slightly in the fourth quarter of this year.

Sources pointed to slow demand for wire bonding and other back-ends for consumer ICs due to inventory adjustments across the consumer electronics industry supply chain.

"The slowdown in consumer electronics demand not only affects second-tier back-end companies, but also leading companies such as ASE. The utilization rate of ASE's main back-end factory in Kaohsiung will drop to between 70%-80% in the fourth quarter of this year." said the source.

ASE has previously said it is too early to comment on the general environment and potential shift in market demand next year.
