IC packagers Advanced Semiconductor Engineering (ASE) and Siliconware Precision Industries (SPIL) have reported sequential decreases of 1.7% and 4.3%, respectively, in January consolidated revenues.

ASE's consolidated revenues, which consist of revenues generated by EMS subsidiary Universal Scientific Industrial (USI), fell 9.3% from a year earlier to NT$21.17 billion (US$639.67 million) in January 2016.

ASE's core assembly test and material (ATM) business posted revenues of NT$11.77 billion in January 2016, down 5.4% on month and 8.3% on year.

SPIL announced consolidated revenues for January 2016 declined 3.7% from a year ago to NT$6.63 billion.

ASE said previously that growth would return to the normal seasonal pattern in the first quarter of 2016, as inventory adjustments in the semiconductor industry have come to an end. The company did not provide its revenue guidance for the quarter.

SPIL also believes that inventory correction in the industry supply chain is near its end. Inventory replenishment is expected to take place at the end of first-quarter 2016, company chairman Bough Lin remarked previously.
